Monitoring intrapartum fetal heart rates by mothers in labour in two public hospitals: an initiative to improve maternal and neonatal healthcare in Liberia
BMC Pregnancy and Childbirth volume 20, Article number: 362 (2020)
In low-resource settings with few health workers, Fetal Heart Rate (FHR) monitoring in labour can be inconsistent and unreliable. An initiative to improve fetal monitoring was implemented in two public hospitals in rural Liberia; the country with the second lowest number of midwives and nurses in the world (1.007 per 10,000 of the population). The initiative assessed the feasibility of educating women in labour to monitor their own FHR and alert a midwife of changes detected.
Four hundred seventy-four women admitted in labour without obstetric complications were approached. Four hundred sixty-one consented to participate (97%) and 13 declined. Those consenting were trained to monitor their FHR using a sonicaid for approximately 1 minute immediately following the end of every uterine contraction and to inform a midwife of changes. If changes were confirmed, standard clinical interventions for fetal distress (lateral tilt, intravenous fluids and oxygen) were undertaken and, when appropriate, accelerated delivery by vacuum or Caesarean section. Participants provided views on their experiences; subsequently categorized into themes. Neonatal outcomes regarding survival, need for resuscitation, presence of birth asphyxia, and treatment were recorded.
Four hundred sixty-one out of 474 women gave consent, of whom 431 of 461 (93%) completed the monitoring themselves. Three hundred eighty-seven of 400 women who gave comments, reported positive and 13 negative experiences. FHR changes were reported in 28 participants and confirmed in 26. Twenty-four of these 26 FHR changes were first identified by mothers. Fetal death was identified on admission during training in one mother. Thirteen neonates required resuscitation, with 12 admitted to the neonatal unit. One developed temporary seizures suggesting birth asphyxia. All 26 neonates were discharged home apparently well. In 2 mothers, previously unrecognized obstetric complications (cord prolapse and Bandl’s ring with obstructed labour) accompanied FHR changes. Resuscitation was needed in 8 neonates without identified FHR changes including one of birth weight 1.3 Kg who could not be resuscitated. There were no intrapartum stillbirths in participants.
Women in labour were able to monitor and detect changes in their FHR. Most found the experience beneficial. The absence of intrapartum stillbirths after admission and the low rate of poor neonatal outcomes are promising and warrant further investigation.
The need to improve identification and management of intrapartum placental insufficiency and fetal distress is particularly relevant in low-income countries, such as Liberia. Yet it is in such settings that the methods and means to do so are severely limited by the lack of health workers and by material poverty. Challenges include the lack of suitably skilled birth attendants, particularly in rural settings; the high workload with each attendant often having to care for several women in active labour, especially during the night; and the lack of resources to fund, maintain and interpret fetal monitoring devices. As quoted by The Lancet Every Newborn Study group: “Sensitive, specific, and simpler methods for detection of fetal compromise during labour could have a major effect on intrapartum stillbirths and early neonatal deaths, as long as linked with emergency obstetric care” .
The scale of the shortage of suitably trained health workers, such as nurses and midwives to undertake any fetal monitoring is highlighted in Table 1, which shows the numbers of nurses and midwives per 10,000 of the population as determined by WHO in 2019 in its Global Health Observatory Data Repository . Seventeen out of 194 countries had < 5.0 midwives and nurses per 10,000 of the population and 15 out of 194 countries had > 100 midwives and nurses per 10,000 of the population.
The two countries with the lowest numbers of midwives and nurses currently recorded by WHO are Somalia and Liberia. Both countries have experienced recent armed conflict. Between 2014 and 2015, Liberia also experienced an Ebola outbreak, which killed many healthcare staff. Unfortunately, since recovery from Ebola, the international community’s statements that they would improve the public health infrastructure of Liberia have not materialized .
Table 1 also shows that high-income countries have more than 100 times the numbers of midwives and nurses than Liberia, available to attend pregnant women and their babies.
Moreover, as a result of increasing inflation in Liberia, (7.4% in 2009 to 22.3% in 2019)  and worsening poverty, the employment of midwives in the public hospitals has reduced, their salaries have decreased, and sometimes, they may not be paid for several consecutive months. Consequently, their morale has fallen, and partographs are infrequently completed according to WHO recommendations. Although the Ministry of Health has made great efforts to educate midwives to recommended international standards , the lack of funds available to the national health service facilities, frequent absence of essential drugs, medical and surgical supplies, together with a lack of international funding, make providing high quality health care difficult to achieve, especially in rural areas where attracting health workers of all levels is difficult.
Labour wards in rural Liberian hospitals are frequently over-crowded with patients and it is unusual for any mother in labour to be accompanied by a relative or for them to receive the levels of attention and care, both to themselves and to their unborn babies, which are essential to prevent and / or treat intrapartum complications.
A study conducted in 2010 in a Liberian referral hospital showed that out of 1656 deliveries in 1 year, there were 196 perinatal deaths; 143 classified as stillbirth and 53 classified as early neonatal death . The majority of stillbirths (56.6%) presented as antenatal stillbirths with no fetal heart sounds documented on admission. Thirty-seven (25.9%) had documented fetal heart rates upon admission with the stillbirth occurring during the intrapartum period. There was no documentation of presence or absence of fetal heart rates in 25 of the stillbirth records (17.5%). Thirty-one percent of cases had no maternal or obstetrical diagnosis recorded in the chart when a stillbirth occurred. Of the 53 early neonatal deaths, 47.2% occurred on the first day of life. The largest single contributor to early neonatal death in the sample was birth asphyxia identified by poor Apgar scores (< 4 at 5 min). Seventeen of the 53 early neonatal deaths (32%) were due to birth asphyxia .
After this health improvement initiative / feasibility study began in July 2017, in February 2018, WHO produced an updated guideline concerning intermittent FHR auscultation during labour using either a Doppler ultrasound device or a Pinard fetal stethoscope  This WHO expert group reported that monitoring of the fetal heart rate during labour was inadequate in many low- and middle-income country (LMIC) settings, and that this problem needed to be strongly addressed through quality improvement initiatives in these settings. A review of qualitative studies exploring women’s experiences of labour and childbirth, suggested that women would prefer a more hands-on, woman-centred approach to care and were likely to favour any technique that allows for this approach,  WHO have also pointed out that Doppler monitoring allows a woman to hear the fetal heartbeat, which provides reassurance and could add to its appeal over Pinard auscultation. WHO’s 2015 State of inequality report , indicates that women who are poor, least educated, and residing in rural and remote areas have lower access to healthcare intervention coverage than more advantaged women. The 2018 WHO guideline  also emphasised studies reporting that adequate monitoring of labour progress is often lacking in such settings, and that the FHR may only rarely be auscultated [10, 11].
Such inadequate FHR monitoring represented the situation in rural public hospitals in Liberia in 2017, which led to the design and implementation of this present initiative.
Globally, intrapartum-related complications are reported to cause an annual 1.2 million stillbirths, 700,000 term newborn deaths, and an estimated 1.2 million newborn babies developing neonatal encephalopathy (birth asphyxia) with 233,000 survivors developing moderate or severe neurodevelopmental impairment . The countries with the highest stillbirth and neonatal mortality rates are in Sub-Saharan Africa , where between 25.1 and 34.2 stillbirths occurring for every 1000 births, with an estimated 51% of these deaths happening intrapartum . For example, in a rural hospital in Tanzania, the stillbirth rate was 27/1000 live births, with 16/1000 occurring intrapartum  and 27% of deaths in the first 6 days of life related to intrapartum causes.
Compared with well-resourced countries, intrapartum-related neonatal mortality rates are 25-fold higher and intrapartum stillbirth rates up to 50 times higher in the lowest-income countries  where rehabilitation services for children with neuro-developmental impairments are poor or absent.
The integration of obstetric and neonatal care to manage complications for both mother and fetus during labour  is critically important with task-sharing being particularly relevant in low resource settings. To the best of our knowledge, mothers have not previously participated in FHR monitoring during labour. Their contribution (as a form of task-sharing) could be valuable for the wellbeing of both themselves and their babies and could be of assistance to overworked health care professionals who are too busy to undertake regular fetal monitoring. WHO recommendations for intrapartum fetal monitoring by midwives may be possible to achieve in well-resourced countries (100–180 nurses and midwives per 10,000 population ) but may be aspirational in poorly resourced countries, such as Liberia, which has 1.007 nurses and midwives per 10,000 population .) As part of a maternal and neonatal health care improvement initiative, we assessed whether maternal participation in monitoring the FHR during labour is a potentially feasible, effective, and sustainable approach to improving intrapartum and neonatal survival in situations with few and overworked skilled birth attendants.
We have used and adhered to the revised standards for quality improvement reporting excellence (SQUIRE 2.0) to report this initiative .
Given the major shortage of midwives in Liberia, the first aim of this initiative, was to assess the feasibility of educating women in labour to assess their FHRs with a portable doppler monitor and to alert the midwife if they detected changes in the FHR which might indicate fetal distress.
The second aim of this initiative was to facilitate system changes to educate and enable the attending midwife, who would likely be caring for several individual women in labour, to initiate an immediate remedial course of action should she/he be alerted by a woman in labour who detected changes in her FHR. The questions posed, and the measured outcomes of this intervention, are shown in Table 2.
In Liberia, over the past 6 years, a partnership between the Ministry of Health and Social Welfare (MOHSW), The World Health Organization (WHO), The United Nations Population Fund (UNFPA), the Liberian Board for Nursing and Midwifery (LBNM) and the registered charity (not-for profit organization), Maternal and Childhealth Advocacy International (known as MCAI), has been established to train senior birth attendants (19 midwives and 2 physician assistants) in advanced obstetrics to become obstetric clinicians, able to undertake emergency clinical procedures to expedite the delivery of a distressed fetus, such as vacuum delivery and Caesarean section . Currently, 10 obstetric clinicians have completed training, 10 more are currently in their final year of training and 9 more have just been appointed following an examination and interview.
More recently, the partnership initiated a new programme to improve neonatal resuscitation and hospital neonatal care by training selected nurses and midwives to become advanced neonatal nurse practitioners (neonatal clinicians) and is now based in both of the two hospitals involved. Currently three have completed their training, 6 are in their final year and 8 have just been appointed following an examination and interview.
The fetal monitoring initiative took place in CB Dunbar Hospital in Bong County and CH Rennie Hospital in Margibi County. The main training hospital for both obstetric clinicians and advanced neonatal nurse practitioners (neonatal clinicians) is CB Dunbar Maternity Hospital. During this initiative and working in these two hospitals, there was one fully qualified and licensed obstetric clinician, 4 trainee obstetric clinicians and 9 trainee neonatal clinicians at CB Dunbar Hospital. There were 5 trainee obstetric clinicians at CH Rennie Hospital but no neonatal clinicians at the time of this feasibility study.
Management committee for this health care improvement initiative
This initiative represented an integrated project between obstetrics and neonatology. Both qualified and trainee obstetric clinicians and trainee neonatal clinicians and their trainers were involved.
The management committee oversaw the day to day running of the initiative and was responsible for the data analysis. If there were any problems identified, in particular involving the need for improving the recording methods, the management committee would make the necessary changes to the initiative as appropriate.
As members of the management committee, two trainee Obstetric Clinicians (KP and NJ), and the international advanced neonatal nurse practitioner (AK) managing the recently established neonatal intensive care unit, led the day to day running of the fetal monitoring component of this initiative.
The fetal monitoring project started as a service delivery intervention; when authors realized the possible significance of the outcomes, we decided to approach the work from a research angle for publication. As a programmatic intervention, it was fully within the domain of the Ministry of Health to implement. Re-framed as a research project, it was relevant to seek National Research Ethics Board approval.
Because of poverty and complex social circumstances, it is common for mothers in Liberia to be aged under 16 years. Also, young mothers frequently attend the hospitals in labour by themselves, with no legally assigned family members in attendance and sometimes only a traditional birth attendant for support. Many women and adolescent girls do not know their age, and the illiteracy rate in Liberia is high (63%) .
Over a 15-month period (from 31 July 2017 to 24 October 2018), 474 women admitted in the active first stage or second stages of labour, who were not experiencing any complications such as haemorrhage, severe pre-eclampsia or obstructed labour, were invited to participate. Before participation, each mother was asked to give her informed consent by a trainee or fully trained obstetric clinician. Initially (given a female literacy rate from UNICEF data 2011–2016  of those aged 15 to 24 years of approximately 37%) this consent was requested verbally and recorded and later (after 27th April 2018) a dedicated consent form was signed (either by fingerprint or in writing).
From the start, all authors considered this work as the implementation of a new project that would improve health service delivery, in particular regarding fetal monitoring during labour. The severe lack of midwives and the infrequency of adequate completion of the partograph, indicated to the authors that this project was an essential part of health service delivery rather than a research study. The project had the prior approval of the Liberian Ministry of Health. As the focus was improved health service delivery and did not involve any invasive procedures, authors initially sought verbal consent from all potential participants. However, as the initial results of the project were so encouraging, authors recognised the value in sharing our experience of this project through a peer-reviewed publication and so changed the consent process to require written consent from all participants. Informed consent, written or verbal, was therefore obtained from all participants.
Throughout, this non-invasive project was supervised by the Liberian Ministry of Health (the original Minister of Health, BD, up to January 2018 and current Minister, WJ, from January 2018 are both authors of this paper).
The seeking of consent, whether verbal or written, was dependent on each woman understanding what was being requested of her. The consent form (part of the Additional File 1) was read out and discussed with each woman before she was enrolled in the study. Only women or adolescent girls (those potential participants aged under 18 years) who fully understood what they were being asked to undertake were recruited. The obstetric clinicians who gained consent were skilled health workers with years of experience in managing pregnant women in Liberian public hospitals. All had undergone a medical ethics and professional standards course as part of their training. Therefore, these health workers were well placed to ascertain if each woman who was invited to participate understood what was required. Each woman could change her mind at any time, and her wishes were always respected.
Plan of investigation
Between contractions, each participating woman was shown and educated by an obstetric clinician in how to use a re-chargeable, battery operated, fetal doppler heart sound monitoring device (a sonicaid), including the best position to place the probe on the mother’s abdomen. This training usually lasted between 10 and 15 min. The mother was also educated in what was a normal heart rate and what was slow or fast, by tapping out a rhythm. Mothers were asked to monitor for approximately a 60 s period immediately following the end of every contraction. However, it wasn’t, in the authors’ opinion, of crucial importance or appropriate to insist that participating women monitor for exactly 60 s, which may be difficult. In addition, it is/was the beginning of the 60 s period that we considered of most clinical relevance to detecting changes in the FHR that might indicate fetal distress.
Having determined what was a normal rate, the mother was then asked to identify and immediately inform a midwife of any changes in the FHR that she detected. In the ward areas in the hospitals undertaking this initiative, there is no buzzer or bell alert and so if a participating woman thought that she had detected a change in FHR, she called out for a midwife or obstetric clinician to come and confirm possible changes. As the labour wards in both hospitals were small, this system worked well. Sometimes, the mothers reported actual heart rates (if literate) but mostly identified a fall or increase in heart rates without counting the numbers involved. The midwives and obstetric clinicians who responded to the mother, recorded and reported the actual heart rates. Additional File 1 contains the form that was used for the recording process which was completed as soon as possible after delivery.
Additional file 2 is a Table containing the comments made on the monitoring process by the mother, either written directly or transcribed for illiterate mothers by the obstetric clinician completing the form. To help with anonymity, age groups for each participant have been used instead of actual ages.
In all participating women, the partograph was supposed to be completed according to WHO recommendations by a midwife on the labour ward every 30 min during the first stage and every 5 min during the second stage of labour [20, 21]. However, in reality, the fetal section of the partograph was inconsistent and rarely completed due to time pressures on the small number of midwives available.
If a participating woman decided that she could not continue to monitor the FHR, for whatever reason, her wishes were respected and documented. If a woman’s condition during labour made it difficult for her to continue making recordings, a midwife or obstetric clinician would, if possible, and if time allowed, assist or take over the monitoring from her with the woman’s permission.
If a woman declined to undertake the monitoring herself but still wanted her fetus to be monitored, with the mother’s permission, the monitoring could be done by a midwife or by an obstetric clinician, provided they had time available given their heavy workloads.
Actions by midwives and/or obstetric clinicians
The midwives working in the two hospitals were informed of the plans and scope of the initiative by the management committee team and educated in their role and responsibilities regarding the initiative, especially that they must, if possible, respond immediately when alerted by the participating women to a change in FHR and to examine the woman. If the FHR was potentially of concern, the midwife would then immediately notify the obstetric clinician and/or doctor on duty who would assist the midwife in the management of labour until the FHR had either recovered or the baby was safely delivered (as per the birth asphyxia prevention protocol: see below). This remedial protocol was already in place on the maternity units should potential fetal distress be detected. However, unfortunately, FHR monitoring as part of the partograph was rarely undertaken prior to this initiative for reasons outlined in the earlier “Background” to this project. At CB Dunbar Hospital, the neonatal clinician on duty would also be asked to be present at the delivery to resuscitate the neonate if necessary.
The birth asphyxia prevention protocol
if a participating woman in labour detected a possible FHR change (bradycardia or tachycardia) she immediately notified an available midwife.
The midwife checked the FHR and the mother’s condition.
If a bradycardia (< 120 beats/minute) or tachycardia (> 160 beats/minute) were present, the midwife immediately notified the obstetric clinician or doctor on duty.
If the FHR was normal, the midwife immediately began a period of continuous fetal monitoring including the time up to the next contraction. She / he also listened to the FHR during the whole of the next contraction and immediately following that contraction.
If a suspicious FHR was detected during the 1 minute following the next contraction, the midwife took the following actions:
ensured the mother was not lying flat on her back by providing left lateral tilt, examined the liquor if membranes had ruptured, and noted whether meconium staining of amniotic fluid was present.
ensured that the obstetric clinician and/or doctor on duty was present.
provided additional inspired oxygen (when available), secured an intravenous cannula and gave a bolus of either 0.9% saline or Ringer Lactate solution and where there was suspicion of ketosis, added a bolus of 50% dextrose to the IV infusion .
If there was evidence of fetal distress (late decelerations, persistent bradycardia, persistent tachycardia, meconium stained liquor) then the mother was assessed by the obstetric clinician or doctor to manage any maternal obstetric problem that could be responsible for the fetal bradycardia/tachycardia and assess for urgent immediate delivery as follows:
If the cervix was fully dilated and there were no contraindications, a vacuum delivery was undertaken.
if the cervix was not fully dilated, then the woman was prepared for an emergency Caesarean section (CS) and taken to the operating theatre where she was re-examined. If the fetus was still alive and the cervix still not fully dilated, a CS was performed. An abdominal ultrasound scan was often helpful at this time, not only to check whether the fetus was still alive, but also related to other clinically relevant issues, such as to determine the lie and position of the fetus and confirm the position of the placenta.
Under either circumstance outlined in 6 above, a neonatal clinician or midwife experienced in neonatal resuscitation, was immediately made available for when the baby is delivered. She/he would ensure that the equipment needed for resuscitation was available and functioning.
The outcome for the mother and baby
The clinical condition of the baby at birth, the need for neonatal resuscitation, admission to the neonatal unit and any signs of subsequent birth asphyxia (also known as Hypoxic Ischaemic Encephalopathy: HIE) were documented. A clinical summary of the pregnancy and delivery was also documented.
The views of the mothers on the fetal monitoring process
From 23rd October 2017, through written or verbal comments (the latter transcribed by the midwife or obstetric clinician), mothers were asked for their views on the monitoring process.
One hundred fifty-three out of 154 participants who had consented at CH Rennie hospital (where the project started on 21st March 2018) were approached for comment (on admission one potential participant’s fetus was found to be dead during her training in monitoring).
This request for comments was not in place for the 33 of the consented mothers, who had enrolled before 23rd September 2017 at CB Dunbar Hospital.
Two authors (DS and RM), categorized the comments retrospectively by first agreeing the common themes after reading all of the comments provided by the participating women. Any discrepancies between DS and RM were discussed and agreed by consensus.
The comments in Table 3 were selected as being representative of the basic themes, as subjectively agreed by the two authors RM and DS. The full set of comments from all participants are available in the Supplementary Information (Additional file 2).
MCAI was responsible for the data analysis and undertook a descriptive analysis.
The lead obstetric clinician in each hospital (KP and NJ) was responsible for charging the batteries and for ensuring gel, consent, and monitoring forms were constantly available. Forms were scanned and sent to the UK by MCAI programme and finance managers in Liberia (Fig. 1).
The project meanwhile, at the time of this publication, continues in both hospitals (see Fig. 2).
Consent and monitoring (see flow chart Fig. 3)
Over 15 months from 31 July 2017 until 24 October 2018, 474 women (157 from CH Rennie and 317 from CB Dunbar Hospitals) admitted in the first or second stages of labour and without obstetric complications were approached. Four hundred sixty-one gave their informed consent to participate in the FHR monitoring (97%) and 13 declined.
CH Rennie hospital data
At CH Rennie Hospital, data were collected from 21 March 2018 until 24 October 2018. One hundred fifty-seven mothers were approached for consent. Three declined [one because of too much pain); for two no reasons were given. In the 3 women who declined, only fetal monitoring as part of the partograph, continued to be undertaken when staff time was available.
Three participants had consented but, after monitoring for 12, 8 and 36 contractions respectively, stopped monitoring because of pain and tiredness.
CB Dunbar hospital data
At CB Dunbar Hospital, data were collected from 31 July 2017 until 24 October 2018. Three hundred seventeen mothers were approached for consent. Three hundred gave their informed consent and 17 declined. In 7 of the 17 who declined, the mothers subsequently changed their minds and undertook monitoring for the rest of their labour. In one of these latter cases, the mother shared her monitoring with her midwife and obstetric clinician. Three hundred and seven mothers thus continued with monitoring their fetus and 10 declined. In 4 of these 10 cases, where the mother said her pain was too much to allow her to do it, and with the woman’s permission, the obstetric clinician and/or midwife continued to undertake the monitoring with the sonicaid. In one of these latter 4 cases a student midwife undertook all of the monitoring and identified a change in FHR (see Table 4). In the other 6 cases, no FHR monitoring was undertaken except as part of the partograph when staff time was available.
Out of the 307 mothers who continued monitoring (see Fig. 3) and in an additional 7 cases, the mothers subsequently stopped monitoring (1 through tiredness, 1 because of pain, 4 with no reasons given and 1 because she “was worried about delivering on time”).
In an additional 20 of the 307 cases where mothers had consented, but then stopped monitoring, a midwife or obstetric clinician took over (19 cases) until delivery or shared the monitoring with the mother (1 case). Of these 20 cases, 15 gave pain and 5 gave tiredness or weakness as the reasons.
Four hundred thirty-one of 474 (91%) mothers approached for consent were able to complete the monitoring themselves (151 from CH Rennie Hospital and 280 from CB Dunbar Hospital): see Fig. 3.
Maternal age was available for 416 of 461 participants. 51 (12%) were aged under 18 years (24 mothers aged 17; 18 mothers aged 16; 5 mothers aged 15; 3 mothers aged 14; and one mother aged 13 years).
Maternal experiences and comments (see Fig. 3)
Four hundred participants provided written or verbal (transcribed) comments on their experiences of the monitoring. Their comments included reference to the lack of any pain control, which was not available during labour in any of the public hospitals in Liberia at the time of this initiative.
Three hundred eighty-seven mothers found listening to their unborn baby a positive experience expressing one or more of the following words or phrases: alright, not bad, good, fine, helpful, loved or liked it, happy, comfortable, gives me joy, or other positive comments such as “Thank you”. A selection of these comments is shown in Tables 3, 4, 5 and 6, including some from mothers who identified changes in FHR. The complete set of comments from all participants are available in the supplementary information (Additional file 2).
Thirteen participants reported only negative comments: 5 reported weakness or tiredness (including feeling nauseated in one case), 6 reported pain (which in 3 interfered with the monitoring), 1 said it was not easy and 1 said it was bad.
Out of the 387 providing positive comments, 86 also reported how much they were affected by pain or severe pain. This pain interfered with their ability to undertake the monitoring in 52 of the 86 (60%).
Within the 387 with positive comments, 44 women also reported discomfort, 5 reported tiredness and weakness and 4 reported difficulties applying the sonicaid.
Three mothers said that they would hope that monitoring would be available during their future pregnancies. Six mothers said they would return to the hospitals to deliver in the future as a result of the project. An additional 6 mothers said they would hope that monitoring will continue to be available so that other mothers can benefit and 5 said they would encourage other mothers to participate. Nine participants said monitoring helped them to cope with labour pain.
Technical and administrative problems identified
As the forms were to be completed by busy obstetric clinicians, not dedicated researchers, forms were designed to record the most relevant information for the purposes of the study objectives rather than detailed information which, although useful, was not necessary for the purposes of this initiative and could have taken the health workers away from their clinical work.
The initial design of the tick sheet documenting each contraction monitored did not always allow enough space to record every contraction and obtaining extension sheets was sometimes a logistic problem. To minimise the workload of the scarce midwifery workforce, forms were also re-designed to record clinical data that were appropriate but not excessive given time restraints.
Due to a communication problem, 57 mothers at CB Dunbar Hospital (between 19 Feb 2018 and 8 May 2018) incorrectly monitored their FHR every 30 min (similar to the partograph). However, unlike the partograph, monitoring was always undertaken for approximately 60 s immediately following the nearest contraction to each 30-min window. We did not identify any clinical differences or differences in experiences between the 57 women who monitored the fetal heart every 30 min and the women who monitored after every contraction.
In 474 mothers approached for consent, there were 33 caesarean sections (7.0 %) including 14 with FHR changes. There were 20 vacuum deliveries (4.2 %) including 8 with FHR changes, (the latter included a mother with a stillborn baby identified during the training in the use of the sonicaid, confirmed by ultrasound scan).
Clinical information and outcomes where FHR changes were identified by monitoring Table 4.
Fetal death was identified on admission during training in the use of the sonicaid in one mother (see Table 4 below).
Table 4 describes the clinical information and outcomes relating to identified FHR changes. Changes in FHR were reported in 28 of 461 participants (6.1%,) which in two cases were not confirmed by the attending midwife, giving 26 confirmed cases (5.6%). Twenty-four of these FHR changes were first identified by their mothers. In 23 of the 26 confirmed cases, the FHR decreased and in 3 the FHR increased. Two changes related to unrecognized obstetric complications, with one mother found to have Bandl’s ring with obstructed labour and the other, cord prolapse.
All 26 neonates with changes identified in FHR survived, including 13 requiring resuscitation at birth. Twelve neonates were admitted to the neonatal unit. One neonate developed birth asphyxia/HIE but the immediate clinical outcomes of the 25 other neonates were good and all 26 were discharged home apparently well.
One of the 26 changes in FHR was identified by a midwife who had taken-over monitoring from a mother who became too tired to continue. In a second case, the mother had declined to undertake monitoring herself but had consented to the monitoring being undertaken by a student midwife.
In 16 of the 26 with confirmed FHR changes, plus 1 intrauterine fetal death detected on admission, there was accompanying meconium-stained liquor.
Thirteen of the 26 (50%) neonates with prior FHR changes had low Apgar scores and needed resuscitation. There were no deaths following resuscitation. One baby had convulsions managed with Phenobarbital, recovered, and was feeding normally at discharge home aged 7 days. None of the other 26 neonates developed birth asphyxia (also known as Hypoxic Ischaemic encephalopathy-HIE). However, long-term infant follow-up was not undertaken.
Seven of the 26 neonates with confirmed FHR changes, plus 1 who had suffered intrauterine fetal death, were born by vacuum, 14 by Caesarean Section (CS) and 5 by vaginal delivery. In one case, CS followed a failed vacuum delivery.
Clinical information and outcomes in 3 newborn infants needing resuscitation at birth where mothers had declined to participate in FHR monitoring. Table 5.
In one such case, the baby was born with Apgar scores of 2 at 1 min and 3 at 5 min and, despite resuscitation, died of HIE in the neonatal unit aged 2 days. In 2 other cases, there were low Apgar scores at 1 and 5 min (4 and 6; and 2 and 6) and the babies needed resuscitation. Both were admitted to the neonatal unit. One responded well to resuscitation with no evidence of HIE and was discharged home well. The other died aged 3 days from birth asphyxia/HIE.
Clinical information and outcomes in newborn infants needing resuscitation at birth where monitoring had not identified any FHR changes. Table 6.
In addition to the neonates requiring resuscitation where FHR changes had been detected, 8 other neonates without detected changes in the FHR required resuscitation (Table 6). Two were of low-birth weight (1.8 and 1.3 Kg). Despite resuscitation for 25 min one of the low birth weight babies died at birth. None of the 7 babies who survived showed evidence of birth asphyxia/HIE.
In one mother, a vacuum delivery was undertaken for inability to push during the second stage of labour., Apgar scores were 5 and 8 and the baby required 10 min of bag and mask ventilation. He was discharged home aged 7 days well. No evidence of birth asphyxia/HIE was evident on clinical assessment.
Three cases were born following vacuum delivery and 5 cases by vaginal delivery. In one mother progress of her fetus was arrested at the perineum and an episiotomy was undertaken to expedite vaginal delivery.
Three of these 8 neonates had been monitored in utero only every 30 min in a temporary deviation to the protocol because of a communication problem with one of the trainee obstetric clinicians but none developed birth asphyxia/HIE.
Costs associated with collecting data
The costs of the project were low. The fetal doppler monitors (Sonicaids: 12 in total) cost USD 40 each. Rechargeable AA batteries were used. Additional costs included paper and printing for the consent, data collection and monitoring forms including the internet costs of scanning and sending them to MCAI for analysis, and KY jelly (or locally available clear hair gel) for interfacing the ultrasound probe with the abdomen: commercial ultrasound gel was too expensive.
Because of problems with the completion of medical records and the work pressure on the health workers involved, it was sometimes difficult to fill the gaps of any missing information, such as birth weights, retrospectively. Every effort was made by the management committee to minimise missing data, especially regarding maternal and neonatal outcomes.
This initiative aimed to assess whether mothers were able to undertake fetal heart rate monitoring of their unborn babies immediately following the end of every contraction during labour in two rural public hospitals in Liberia, a country with extremely poor resources (both human and material). As 93% of consenting mothers were able to undertake the monitoring themselves until their baby was born, the results suggest that this approach is feasible.
The comments and feedback from the participating women and adolescent girls (not just those selected in the Maternal Comment sections of the tables but also the complete set of comments provided in Additional File 2 as supplementary information), showed that the overwhelming response (387 out of 400) was positive, with several comments reflecting how the monitoring helped a women/ adolescent girl “feel strong”, cope with the pain of labour, or made her feel closer to her baby.
In our experience, it is most unusual for mothers in Liberia (as in many other low-resource settings where the hospital workforce is so limited and stretched) to be asked for their opinions on their experiences of labour and how it was managed. We asked for their opinions in an open way and did not raise the question as to whether they would prefer any alternative approaches to fetal monitoring, as stretched resources, lack of health workers, and subsequent high workloads, made such alternative approaches unfeasible. Also, as explained in our Background, without this approach, many women would not have had her fetus routinely monitored because of the scarcity and high workload of midwives.
To go through a pregnancy only to have a fetus or baby die because of a preventable condition that might have been detected by adequate fetal monitoring is a tragic and traumatic experience. This initiative may have helped to prevent some deaths, while helping women/adolescent girls feel involved in what was happening to them and their babies during labour.
Studies of mothers assisting midwives in monitoring the FHRs of their unborn babies have not been previously reported, as far as we can identify, so it is difficult to compare our results with other studies.
This initiative confirmed that midwives responded to alerts from mothers regarding changes in FHR in a timely fashion and that trained, senior, health professionals (obstetric clinicians and doctors) were able to intervene appropriately and promptly. In 26 out of 461 women undertaking monitoring (in one undertaken with consent by a student midwife and the other by the midwife who took over from the mother who became tired), confirmed changes in fetal heart rates were identified. Actions to improve the placental circulation (such as lateral tilt, oxygen and intravenous fluids), and, where possible, expedited delivery by vacuum or Caesarean section were undertaken following standard obstetric management as recommended by WHO .
All 26 neonates with changes in FHR survived, including 13 requiring resuscitation at birth. Ten neonates were admitted to the neonatal unit. One neonate developed birth asphyxia/HIE, but the immediate clinical outcomes of the 25 other neonates were good and all 26 were discharged home apparently well. However, long-term infant follow-up was not undertaken and should be in the future. The presence of neonatal clinicians and a functioning neonatal unit at CB Dunbar hospital were particularly valuable. Neonatal units that can provide advanced neonatal care by appropriately trained nursing staff (also a form of task-sharing) have now been established at 2 other rural county hospitals in Liberia.
In two mothers, the identification of FHR changes revealed previously unrecognized life-threatening obstetric complications. More experience may identify whether maternal FHR monitoring can consistently identify obstetric complications. Our results support Hofmeyr and colleagues  who stressed the importance of task-sharing in the integration of obstetric and neonatal care. Rapid access to effective obstetric management if FHR changes are identified must be ensured. Fetal monitoring in isolation has little value without an available health support system so that appropriate clinical intervention can be promptly undertaken. This situation may not be the case in some resource-limited settings, limiting the applicability of maternal fetal monitoring.
Comparing figures with those from Tanzania  and from Sub-Saharan African countries [1, 12, 13, 15], the absence of intrapartum stillbirths in the 461 fetuses monitored is encouraging, as is the low prevalence of birth asphyxia/HIE. However, given no comparator, we cannot conclude that stillbirths and birth asphyxia/HIE can be prevented or reduced by maternal FHR monitoring. However, in reality, the lack of comparator data is represented by almost no fetal monitoring in public health hospitals in Liberia. We considered having a control group for this study, but decided that given the situation described in the “Background”, such an approach would have been difficult. However, partway through this initiative, data on neonatal deaths and intrapartum stillbirths began to be collected by the Ministry of Health in Liberia. In the future, such data may provide control information for those maternity facilities where maternal FHR monitoring has not yet been undertaken.
Since we do not have robust baseline (comparator) data we cannot at this stage comment on whether Caesarean Section or operative vaginal delivery rates were increased or decreased by maternal FHR monitoring.
This initiative was conducted in a “real world” setting and suggests that maternal fetal monitoring can be incorporated into the daily work of a busy hospital maternity unit. The constant presence of obstetric clinicians was of considerable assistance, but such experienced health professionals may not always be available and alternative plans to address the health-workforce-shortage may be needed. Even with this additional cadre, communication and adherence to the study protocol were sometimes difficult, depending on the enthusiasm and involvement of all health professionals. Feedback of results to the midwifery workforce appeared helpful. Although we did not explicitly seek the views of attending midwives, which was a major limitation, the finding that midwives sometimes took over the monitoring if a woman was too tired or in too much pain to do it herself, shows their engagement in the process. More information from midwives could also be useful in helping to improve this technique, make it more sustainable, and give a further guide to the additional time needed to undertake maternal-fetal monitoring.
The potential for blaming mothers if there is an adverse outcome for their baby due to perceived failings in their self-monitoring is a very important consideration. However, there was no evidence that this situation happened, and, in our view, potential blame is unlikely as sadly, neonatal death and stillbirths are such common experiences in Liberia, that such events are almost expected.
We appreciate the frequency of monitoring can be onerous for some women, but there was no provision for birth partners or other relatives to be with women during labour, because of shortage of space and lack of privacy. We are planning to address this situation in the future.
Developments and possible ways forward
The long-term solution to fetal monitoring and improving the care of women in labour and their babies is undoubtedly to increase the availability of trained midwives. However, as explained in the “Background” to this paper, and especially the Global WHO/World Bank data concerning midwives and nurses , given the current situation in Liberia and many other low income settings with minimal midwives and nurses, a vast amount of resources and an increase is suitably trained health workers would be necessary to meet this goal, which is not possible in the short-term. However, once and if this situation is achieved, given the positive responses of participating mothers, we would continue to consider that the involvement of mothers in fetal monitoring may work well in collaboration with the enhanced role of skilled birth attendants.
The need for resuscitation in 8 of 461 (1.7%) of babies born without FHR changes identified by maternal monitoring, requires future research to ascertain whether changes are being missed or whether in some cases there are no measurable FHR changes identifiable by this monitoring technique in fetuses who subsequently require resuscitation. In particular, it is important to know whether mothers and/or midwives can monitor reliably after every contraction with the same quality during the end of the first and second stages of labour when contractions can be much more painful.
When appropriately undertaken and documented, with timely responses by care givers, the partograph is of major value in monitoring the progress of labour and safety of mother and her fetus. In support of Hofmeyr et al.  who stressed the importance of task-sharing (in this case involving mothers), our findings show that it is feasible for pregnant women to undertake fetal heart monitoring during labour so that changes in FHR in relation to the end of every contraction are monitored. A decrease in FHR that persists after the end of a contraction, or continues after a contraction, is more likely to be pathological (Type 2 decelerations). WHO recommendations in place at the beginning this initiative [20, 21] specified FHR documentation on the partograph every 30 min in the first stage and every 5 min in the second stage of labour and not with every uterine contraction, as in our initiative. Moreover, in these earlier guidelines , WHO had recommended that the FHR be listened to immediately following the end of a contraction ONLY during 1) the initial assessment of the mother during labour; 2) when malpresentation or malposition are present; and 3) when inducing or augmenting labour. However, during the implementation of this initiative, in February 2018, WHO updated its guidelines on intermittent FHR auscultation in labour, now recommending auscultation every 15–30 min during the first stage, and every 5 min during the second stage of labour stating that auscultation should begin during a contraction and continue for at least 30 s after the contraction has ended . These latest guidelines also recommend that if the FHR is not always within the normal range (110–160 bpm), auscultation should be prolonged to cover at least 3 contractions and also recommend recording the baseline FHR and the presence or absence of accelerations and decelerations . These updates in guidelines are welcome but, in our opinion, are quite complex, difficult to implement in facilities where there are few midwives, and do not concentrate on the most important time for intermittent auscultation, that is, at the end of every contraction. Our approach which involved auscultation from the end of every contraction, was relatively easy to teach, convenient and feasible for individual mothers to undertake, and covered the most critical time for monitoring. For low resource settings, this approach may merit consideration by WHO and the wider international community.
Future expansion of the project to include the possible role of female relatives and traditional birth attendants in supporting the mothers during monitoring, especially at times when contractions are particularly frequent and painful around the end of the first stage and during the second stages of labour, could be helpful. Unfortunately, the lack of space, privacy and resources such as toilets in the labour and delivery wards at present does not readily support this approach. Helpers such as traditional birth attendants or nurse aides may also be of value in collecting baseline/comparative data, and feedback from midwives.
An introduction to self-fetal monitoring during labour at antenatal visits would be beneficial, noting that a significant proportion of pregnant women in rural Liberia do not always attend their assigned antenatal clinics.
The mothers’ comments on the lack of any pain control were of great concern and several mothers were clear about the need for pain control during labour. We have now followed up on the need for adequate pain control during labour within the Liberian Ministry of Health and Social Welfare and have started a clinical audit on the use of intravenous paracetamol at CB Dunbar Hospital.
Some mothers stated that they would encourage relatives and friends to attend the hospitals involved in this initiative so that they might benefit from the fetal monitoring process. Given the encouraging findings of this study, we suggest that other hospitals in low resource settings, where there are few midwives and consequently, inconsistent fetal monitoring on the partograph, consider introducing maternal FHR monitoring, possibly assisted by relatives where circumstances allow. Although a small minority of mothers expressed negative comments, there does not appear, to the best of our knowledge, to have been have any negative clinical consequences to maternal fetal monitoring. Given the circumstances in countries where there are so few nurses and midwives, this approach supports realizing the rights of adolescent girls and women by enabling them to become more involved in their health care and the welfare of themselves and their unborn babies.
This initiative is continuing in both CH Rennie and CB Dunbar hospitals with further expansion planned in the near future to three additional rural maternity hospitals in Liberia.
The most promising findings of this initiative were the ability of the mothers to detect fetal heart rate changes and for midwives, obstetric clinicians and doctors to urgently respond to confirmed changes with appropriate clinical actions. The absence of intrapartum stillbirths, and the low rates of resuscitation and subsequent birth asphyxia/HIE in neonates who had been monitored are encouraging. A welcome finding was the positive comments made by 387 of 400 mothers about their involvement in the monitoring of their own unborn babies. If further studies in other settings, involving much larger numbers, continue to show these benefits, this new approach may help to reduce the devastating problems of intrapartum stillbirth and birth asphyxia / HIE that are so prevalent in low resource settings.

Ethics approval and consent to participate
Informed consent, written or verbal, was obtained from all participants in this project.
In accordance with 45 CFR 46 the research was approved by the National Research Ethics Board (NREB) of Liberia through a full board review. The federal wide assurance number of the NREB is 000 21658 and organisation number 000 8374. This approval was given after reviewing the documents relating to the initiative FHR monitoring project, which included the protocol stipulation that all mothers in labour (themselves individually and whatever their ages) would give their informed consent to be involved in the initiative (FHR monitoring project).
Because of poverty and complex social circumstances, it is common for mothers in Liberia to be aged under 16 years. Also, young mothers frequently attend the hospitals in labour by themselves, with no legally assigned family members in attendance and sometimes only a traditional birth attendant for support. Many women and adolescent girls do not know their age. Nine participants were aged under 16 years; despite their age, these young participants were deemed to be competent to give informed consent to be involved in the monitoring project as per the approved study protocol. Further consent from their parents or guardians was not sought.
Consent for publication
Written consent for publication was obtained from the participant included in Fig. 1, as stated in the Legend to this figure in the Methods section. This was obtained using an MCAI consent form and is available on request.

Additional file 1. Master copy of the consent form, fetal heart rate monitoring and data collection and maternal comment form. This form describes the way in which data were documented and collected on each participant. The consent form provides the information that was either read by each participating mother, if literate, or read to the mother by the obstetric clinician. The form could either be signed by the mother or she could provide her fingerprint from an ink pad. The FHR monitoring form was given to each mother who was asked to tick each time she listened to the FHR for approximately one minute following the end of every uterine contraction. If the mother considered that the FHR had changed, she would notify the midwife caring for her who would check the FHR, count it, and write down her own findings on this chart. If the midwife considered that there was a potentially clinically relevant change in FHR she/he immediately notified the on-call obstetric clinician or doctor. The data collection form recorded a summary of potentially relevant clinical data on the labour, delivery, neonatal Apgar Scores at 1 and 5 min, and any resuscitation given to the baby. Recorded on this form was any admission of the neonate to the neonatal unit and any treatment given to the baby. The form also includes a section in which the comments made by mothers on their experience of the monitoring were recorded either by themselves or as transcribed by the attending midwife or obstetric clinician.
Additional file 2. Table of all maternal comments on their experience of undertaking monitoring of their unborn babies during labour categorised by age groups. This file describes the actual comments made on the monitoring process by each mother, either written directly or transcribed for illiterate mothers by the attending obstetric clinician.
