Abstract

Background

Women from low-income settings have higher risk of maternal near miss (MNM) and suboptimal care than natives in high-income countries. Iran is the second largest host country for Afghan refugees in the world. Our aim was to investigate whether care quality for MNM differed between Iranians and Afghans and identify potential preventable attributes of MNM.

Methods

An MNM audit study was conducted from 2012 to 2014 at three university hospitals in Tehran. Auditors evaluated the quality of care by reviewing the hospital records of 76 MNM cases (54 Iranians, 22 Afghans) and considering additional input from interviews with patients and professionals. Main outcomes were frequency of suboptimal care and the preventable attributes of MNM. Crude and adjusted odds ratios with confidence intervals for the independent predictors were examined.

Results

Afghan MNM faced suboptimal care more frequently than Iranians after adjusting for educational level, family income, and insurance status. Above two-thirds (71%, 54/76) of MNM cases were potentially avoidable. Preventable factors were mostly provider-related (85%, 46/54), but patient- (31%, 17/54) and health system-related factors (26%, 14/54) were also important. Delayed recognition, misdiagnosis, inappropriate care plan, delays in care-seeking, and costly care services were the main potentially preventable attributes of MNM.

Conclusions

Afghan mothers faced inequality in obstetric care. Suboptimal care was provided in a majority of preventable near-miss events. Improving obstetric practice and targeting migrants’ specific needs during pregnancy may avert near-miss outcomes.

Background

Disparities in maternal outcomes between migrants from low-income settings and natives in high-income countries are well documented in the literature [1, 2]. Migrants’ vulnerability to poor pregnancy outcomes is partly explained by individual high-risk profiles such as comorbidities and socioeconomic disadvantages [3, 4]. Furthermore, suboptimal care due to incongruent language and communication barriers, and unequal access to obstetric services are more frequent in migrant populations than European natives [3, 5].

Iran, with 79 million inhabitants, hosts refugees from neighbouring countries and accommodates an estimated one million registered and over two million unregistered migrants from Afghanistan [6, 7]. Essential interventions have been scaled up in this country and institutional delivery of 95% and a 75% reduction in maternal mortality ratio (25 per 100,000 live births) between 1990 and 2015 indicate healthcare achievements [8, 9]. Iran has faced international sanctions and financial constraints in recent decades and health resources have been inadequate to provide universal coverage for public health [10]. Therefore, in-patient care was covered by health insurance for 90% of Iranians, while migrants were uninsured before the initiation of the new health system reform and public access to the Salamat Insurance Scheme in 2015 [7, 10]. Our recent study in Tehran showed an increased risk of maternal near miss (MNM) among Afghan migrants through a lack of health insurance [11]. Iranians and Afghans have similar religious backgrounds and the majority of Afghans speak a language (Dari) similar to that of their hosts (Farsi). Therefore, the communication barriers to optimal care for migrants described in high-income settings appear to be less applicable in this context [3, 12].

MNM is defined as a woman who survives life-threatening conditions during pregnancy, childbirth, or within six weeks postpartum [13]. As high-quality care is crucial in saving lives, World Health Organization (WHO) developed a MNM audit approach in 2011 to routinely evaluate obstetric care quality in health facilities [13].

This study aimed at evaluating whether care quality differed between Iranian and Afghan mothers with near-miss morbidity using the WHO approach. Additionally, we sought to identify potentially preventable factors predisposing to MNM.

Methods

This audit study was part of an MNM project that was conducted between March 2012 and May 2014 at three hospitals affiliated with the Shahid Beheshti University of Medical Sciences in Tehran. Approximately 140 public and private hospitals provide care services in Tehran and the caesarean section (CS) rate stands at 74% [14]. Antenatal visits are included in primary health care and are provided free of charge for both natives and migrants.

Study sites were a secondary hospital with over 4,500 annual births and two tertiary referral hospitals with over 600 and 1,000 deliveries per year, respectively. The obstetric wards were staffed with 21 consultants and 68 residents in obstetrics and gynaecology, and 46 midwives. Consultants, residents, and midwives provide 24-hour medical staffing using national and local guidelines for obstetric care provision. Residents, under supervision of consultants, are responsible for all deliveries regardless of risk and nationality. The study hospitals provided intensive care services for adults and neonates.

At each hospital, one consultant and one resident were selected as research group members. The residents identified MNM cases under supervision of the consultants during daily morning reports. The WHO MNM criteria were used to identify cases prospectively during the first phase of the MNM project [13]. However, these criteria were modified slightly in the case of two indicators in order to minimise inappropriate exclusion of women whose lives were seriously endangered due to obstetric complications but who did not fulfil the WHO criteria due to a limited institutional resources [13]. As the secondary hospital had limited access to blood products (Rh-negative blood types in particular), modified criteria were the administration of four or more units of blood products and a rapid reduction of platelet count to below 75,000 platelets/ml. An acute decrease of ≥4 g/dl in the haemoglobin concentration was also applied as a near-miss criterion. Figure 1 shows the study population.

Maternal age (<20, 20–34, ≥35 years), parity (0, 1–2, ≥3 para), and body mass index (BMI) (<18.5: underweight, 18.5–24.9: normal weight, ≥25: overweight and obese) were considered as maternal factors. Level of education (illiteracy and primary, secondary and higher), family income (low if it barely covered household expenditures, medium if it paid such bills, and high if it was more than self-reported expenses), health insurance (representing occupational status of the woman or her husband), and nationality (Iranian and Afghan according to country of birth) were identified as socioeconomic factors. Antenatal care coverage (at least four visits), timing of the near-miss event (upon or after arrival), admission status (primary or referral), previous CS, CS delivery in present pregnancy, night-shift delivery (2 o’clock pm till 8 o’clock am), severe anaemia (haemoglobin ≤10 g/dl), and comorbidity (diabetes, chronic hypertension, haematological disorders, previous pelvic operation) were assessed as medical factors.

Audit procedure

The main researcher primarily reviewed patients’ records, including admission, operation, and nurses’ notes, ordering sheets, laboratory and pathology reports, and summary notes. For each case, a research form was completed with all background data including obstetric history, and clinical data related to near-miss events, as well as a copy of cardiotocoghraphy (CTG) traces and other available documents.

Three auditors, a Maternal Foetal Medicine physician and two board-certified obstetricians, comprised the audit team. During the study period, the main researcher organised audit panels and presented case histories anonymously (in terms of identity, nationality, and the hospital) to these panels. Auditors used a conceptual framework (Fig. 2) and performed individual case note review to evaluate obstetric care quality and preventability of near-miss events. Additionally, when documentation was insufficient for making clinical judgments, the main researcher interviewed those professionals identified as being the care providers responsible for the particular case to obtain clinical information. Thirdly, 24 near-miss mothers (16 in-person and 8 phone calls) were interviewed to provide additional ideas and input. For each case, the quality of eight care items was audited and the final decision was achieved by consensus among the three auditors (case exemplars are shown in Tables 1, 2 and 3). Antenatal care and referral systems (two items) were assessed to evaluate the quality of pre-hospital care. The quality of hospital care was analysed using a systematic approach based on six items: initial assessment, recognition, appropriate care plan, monitoring of critical conditions, provision of adequate information to women at discharge and planned follow-up, as well as proper documentation [15]. Pre-hospital obstetric care was labelled suboptimal if either antenatal care or referral system was inadequate (≥50% of items). Hospital care was considered suboptimal when three or more of those six items (≥50%) were inadequate. It was possible for one woman with near-miss morbidity to experience several inadequate items and preventable factors during the period of her hospitalisation.

In addition, auditors discussed preventability of near-miss events and agreed on the potential factors that could have prevented MNM or minimised the severity of the events at three levels: provider, patient, and health system [16, 17].

Statistical analysis

Chi-square test was used to examine and compare background factors, severe complications, and near-miss events between Iranians and Afghans. Statistical Package for the Social Sciences software, Version 21, was used for statistical analysis. Differences were considered significant where a probability of less than 0.05 was found. The association between suboptimal care and those factors that were significantly different between Iranians and Afghans was assessed by crude and adjusted odds ratios (OR, AOR) in three models. Health insurance was found protective against MNM and all Afghans and a number of Iranians were uninsured [11]. Therefore, a new independent variable was created and named “insurance-nationality” with three categories: insured Iranian, uninsured Iranian, and uninsured Afghan to examine the effect of lacking insurance on receiving suboptimal care for both nationalities. Model 1 represented crude associations between suboptimal care and maternal education, family income, nationality, insurance, and insurance-nationality. In Model 2, maternal education, family income, and nationality were taken into account to identify independent predictors of suboptimal care. In Model 3, “insurance-nationality” was added as a substitute for “nationality” in Model 2. The independent variables were controlled for collinearity.

Results

Table 1 and 2 show a comparison between women’s background factors and severe obstetric complications as well as near-miss events for Iranians and Afghans. Socioeconomic factors in women’s background variables of 76 cases, differed significantly between Iranians and Afghans. Severe postpartum haemorrhage and severe preeclampsia/eclampsia were the most frequent obstetric complications that both MNM groups experienced. On average, each Iranian and Afghan woman developed 2.3 and 2.6 near-miss events, respectively.

Audit findings

Generally, inadequate care items were identified in 85% (65/76) of cases. The majority of cases (62%, 47/76) had already developed a critical condition upon arrival or developed a near-miss event within six hours of admission. The proportion of inadequate items for pre-hospital care was similar for both nationalities. However, inadequate items for hospital care were more frequent among Afghan cases than Iranians [OR 2.7, 95% confidence interval (CI): 1.8–4.1].

Suboptimal care was identified in 70% (38/54) of Iranians and 86% (19/22) of Afghans. While suboptimal care at pre-hospital level was similar for both nationalities (OR 2.2, 95% CI: 0.8–6.0), at the hospital it was disproportionately more common in Afghan cases (OR 4.5, CI: 1.3–15.0). Model 1 in Table 3 shows that being illiterate or having primary education, low-income status, and being Afghan increased odds of receiving suboptimal care. On the contrary, health insurance protected mothers against suboptimal care. The association between suboptimal hospital care and Afghan nationality remained significant after adjusting for maternal education and income (Model 2 in Table 3) and even after additional adjustment for the effect of health insurance (Model 3 in Table 3).

Auditors determined that 71% (54/76) of MNM cases had at least one near-miss event that could have potentially been prevented. Preventability of near-miss events was not different between Iranians and Afghans (67%, 36/54 versus 81%, 18/22; p-value: 0.2). As Table 4 shows, although provider-related factors were involved in majority of cases with preventable events, patient— and health system-related factors could also prevent the development of MNM. The following sections describe related examples of missed opportunities to optimal care.

In 82% (23/28) of MNM cases of severe postpartum haemorrhage, the amount of blood loss was neither estimated nor adequately assessed. Moreover, delayed recognition of the severity of haemorrhage and inadequate stepwise management were identified in 57% (16/28) of cases. Initial assessment in 61% (16/26) of MNM cases of hypertensive disorders was inadequate. Emergency CS due to severe pre-eclampsia was performed in 21 cases, of which 71% (15/21) occurred before stabilisation and treatment of severe hypertension. While placenta previa was the third most common obstetric complication (10%, 8/76) that led to near-miss morbidity, pre-surgical evaluation and the decision process for adopting a surgical approach was missed in 50% of cases.

Three women with preterm pregnancy and co-existing epilepsy arrived at hospital with uncontrollable fits due to either discontinuation of treatment or irregular use of anticonvulsive therapy. They were delivered by emergency CS on suspicion of eclampsia while adequate history taking and initial assessment did not take place. Audits of CTG traces could only confirm abnormal CTG in 20% of those near-miss cases that delivered by CS due to foetal distress. There was no CTG documentation confirming foetal distress in 60% of cases and the opportunity for adequate assessment of CTG trace was missed in the remaining 20%. Tables 5, 6 and 7 present examples of MNM cases and the related clinical judgements.
Table 5

Example of missed opportunities linked to care items for obstetric haemorrhage

Case 1

A 21-year-old Afghan mother, 0P, in 38 weeks of gestation, was admitted to hospital with labour pains in latent phase. She was delivered by emergency CS due to foetal distress on the day shift. Ten hours after operation she was pale, had pre-shock status, and the reported haemoglobin level was 7.4 g/dl. Re-operation was performed, a very large hematoma in left broad ligament was detected, and 12 units of different blood products were transfused. She went back to the hospital two weeks after discharge due to fever and haematuria. Further examination revealed left ureter injury.

Care items

Audit findings

Initial assessment

Foetal heart rates were monitored and assessed inadequately.

Recognition

No evidence was found to agree foetal distress.

Intra-abdominal hematoma was recognised with delay.

Care plan

The indicated evidence for emergency CS was missing.

Monitoring

Postpartum controls early after CS were not documented and were inadequate for early detection of intra-abdominal bleeding.

Preventability

Near-miss events (decreased haemoglobin, re-operation, blood transfusion) and the injured ureter could have potentially been prevented by better obstetric practice (provider-related).

Table 6

Example of missed opportunities linked to care items for placenta previa

Case 2

A 36-year-old native mother, 2P, with two previous CS was admitted to hospital due to low back pain in 39 + 3 weeks of gestation. According to ultrasound examinations during antenatal visits, she had low-lying placenta previa. Emergency CS was performed two hours after admission on the night shift and the operation ended up with CS hysterectomy due to abnormal invasive placenta. More than 20 units of blood products were transfused, the mother was admitted at intensive care unit and had long-lasting intubation. Pathologic examination of uterus specimen revealed placenta increta.

Care items

Audit findings

Antenatal care

Despite two previous CS and low-lying placenta previa, examination of placental orientation for better obstetric plan during pregnancy was not conducted.

Despite repeat CS and previa, no elective surgery was planned.

Referral system

No timely referral from antenatal clinic to the hospital was made.

Initial assessment

Despite risk for abnormal invasive placenta, no assessment at hospital was performed.

Recognition

Recognition of abnormally invasive placenta in a high-risk mother was missed before operation room.

Care plan

No evidence was found indicating acute CS on the night shift for a high-risk surgery.

Documentation

Estimation of blood loss during operation was not documented.

Near-miss events such as the amount of administered blood, admission to intensive care unit, and long-lasting intubation were not documented in summary notes.

Preventability

The near-miss events could have potentially become less critical and traumatic for woman and her family by better obstetric practice (provider-related).

Table 7

Example of missed opportunities linked with sepsis and postpartum haemorrhage

Case 3

A 24-year-old Afghan mother, 3P, was admitted to hospital one week after home delivery with long-lasting bleeding, weakness, and high fever. She was in pre-shock status and the reported haemoglobin level was 5.6 g/dl. She was resuscitated with blood transfusion and was treated with intravenous antibiotic due to postpartum endometritis. Ultrasound examination was done after three days and retained placenta was detected. Fever went down after evacuation and curettage and she chose to leave the hospital before doctor’s recommendation. She was interviewed afterward and said that the family could not afford the cost of hospital obstetric services.

Care items

Audit findings

Initial assessment

Despite home delivery and the risk of retained placenta, history taking and initial examination of uterus cavity were incomplete.

Recognition

Delayed recognition of retained placenta in a mother with anaemia and postpartum endometritis was identified.

Care plan

The management of postpartum endometritis and retained placenta were inappropriate.

Documentation

Previous obstetric history and risk of postpartum haemorrhage, antenatal visits and delivery process at home for index pregnancy were not documented.

Preventability

The near-miss events could have potentially prevented by affordable safe childbirth (health system) and timely care-seeking (patient). Hospital care was also suboptimal.

Discussion

Our findings demonstrate that obstetric care at hospital was more suboptimal for Afghan MNMs than Iranians. Moreover, care providers by optimal performance could potentially prevent a majority of near-miss events.

In contrary to literature, differences in background profiles, socioeconomic factors, language, and religion between Iranians and Afghans could hardly explain our findings [4, 16, 18]. Having a low level of education is a well-known association with increased risk of adverse maternal outcomes by delayed care-seeking and poor compliance with treatments [19]. All Afghans in the present study were uninsured and had a lower level of education compared to Iranians; however, the proportion of near misses upon arrival did not differ between Iranians and Afghans. While suboptimal care was more probable for uninsured Afghans, this probability was not found for uninsured Iranians. Moreover, having insurance coverage in European countries is inadequate to protect immigrants from disproportionate suboptimal care [5, 12]. Social differentiation, isolation, and women’s self-perceptions can dissociate mothers from adequate care [20]. These factors among Afghans could affect obstetric care quality but this study was unable to elaborate on such factors.

In accordance with prior studies, we found that care providers had fundamental roles in the prevention of near-miss morbidity by making timely diagnosis and successful management of obstetric complications [16, 21]. Auditors noticed that although guidelines were accessible to care professionals, medical management poorly adhered to them. Literature suggests that in addition to establishing guidelines, optimal care provision requires providers’ beliefs and institutional support [22]. Conducting audits in obstetrics can provide practical measures for tackling care deficiencies and may stimulate tailored interventions to improve maternal care quality [23, 24].

In agreement with other publications, we found that patient- and health system-related factors were involved in preventable near-miss events [3, 16]. For instance, home delivery or delayed care-seeking that may result from financial constraints at patient level could have been avoided by insurance coverage at the level of health system. Although healthy motherhood is part of women’s rights to health and life, poverty seriously affects these rights when the needed care is available but unaffordable [25].

To our knowledge, the present study is the first attempt to apply the WHO MNM audit in Iran to evaluate care quality within a migration perspective. Using the WHO criteria was feasible to identify MNM cases prospectively in our setting, while the MNM tool failed to identify all eligible cases within a national data in the Netherlands, retrospectively [26]. Collecting first-hand data from near-miss survivors and care providers was a real strength in our study and disclosed valuable inputs that might not have been identified by reviewing the case notes alone. The audit framework enabled us to identify major obstacles to optimal care provision and facilitated determining barriers against accessing to such care. Moreover, the classification of potential preventable attributes of MNM into provider-, patient-, and health system-related factors might have a qualitative value in revealing where and how the tailored interventions could avert near-miss outcomes [17]. As missed opportunities to better manage severe complications were found repeatedly at all of the study hospitals, the identified quality might mirror those of other university hospitals in Tehran.

The main limitation of this audit study is that our findings are based on a small sample of MNM cases. As the WHO near-miss approach underlines, the optimum number of cases for evaluating care quality has not been established [13]. Our small sample could be an explanation for the non-significance of preventable factors between Iranians and Afghans. Another limitation is improper documentation. For instance, no records from the first institute or from professionals who referred patients to the tertiary hospitals were found, and antenatal cards were mostly unavailable. The quality of pre-hospital care was assessed based on the information extracted from the hospital admission notes and the additional input that was given by a few survivors and could thus be underestimated. We were unable to make contact with a majority of near-miss mothers for interviews. Furthermore, an interviewer who was not an obstetric professional could have received other responses or provided other input to the audits. Two auditors worked as consultant obstetricians at the study sites, one in tertiary and one in the secondary hospital, and this may have impacted on their judgements of care quality at their hospitals. However, MNM cases were presented anonymously at panels and auditors were unaware of the cases’ nationality or the place in which they were treated.

Conclusion

Inequalities in maternal care between Iranians and Afghan migrants were identified. The majority of near-miss events were considered preventable and audits suggested areas for improvements. The results may draw the attention of policy makers for adopting a maternal morbidity surveillance and response system to tackle care disparities and address obstacles in obstetrics. Afghan women affected by many socioeconomic and humanitarian challenges that should gain additional attention within antenatal visits.
