Study design, setting, and period
This Facility based comparative cross-sectional study was conducted in Bahir Dar city from April to May 2018. The city is located in Amhara Regional State North West Ethiopia, which is 565 km apart from Addis Ababa, the capital city of Ethiopia. Based on the 2017 population projection, the city had a total population of 321, 343 of which 108, 295 were females. The total number of non-pregnant reproductive age women (15–49 years) was 42,957. There are 9 sub-cities in Bahir Dar city. According to the City Health Department, the health infrastructure of the zone is organized by one governmental specialized referral hospital, one primary hospital, and ten health centers. There are also two private hospitals and ten private clinics. There are four hospitals, one health center and one non-governmental clinic that provides both delivery care services [12].
Population
All term pregnant mothers who visited dual delivery care health facilities were the source population. And term mothers who visited these health facilities during the data collection period were the study population.
Sample size determination
The sample size was calculated using the formula for two population proportions with the level of women’s satisfaction between vaginal and cesarean section among the study participants in previous studies was not known; thus, the 10% difference in the proportions between vaginal delivery (P1 = 50%) and cesarean delivery (P2 = 40%), 1:1 ratio between vaginal and cesarean delivery, power = 80%, confidence level = 95% (1.96) was assumed. The formula can be seen below.
$$ {\mathrm{n}}_1=\frac{{\left[{Z}_{\frac{\alpha }{2}}\sqrt{\left(1+\frac{1}{r}\right)P\left(1-P\right)+{Z}_{\beta}\sqrt{P_1\left(1-{P}_1\right)+\frac{P_2\left(1-{P}_2\right)}{r}}}\right]}^2}{{\left({P}_1-{P}_2\right)}^2} $$
By considering a 10% non-response rate, the final sample size was 896.
Sampling procedure
Mothers who delivered in one of the six dual delivery care, providing health facilities were selected for the study. Proportion to size allocation was made to determine the required sample size from each health facility based on the previous 3 months delivery care attendants. The systematic random sampling technique was used until the required sample size was achieved in each health facility. The Kth value was calculated based on the number of registered for delivery care on the day divided by expected sample a day (in each health facility). The total number of mothers who gave birth in the study period was 2481, (640 via cesarean section and 1841 via the vaginal route). From the first Kth values, one mother was selected by lottery method. The consecutive delivering mother was recruited by every Kth value. Finally, from each 896 delivering mothers (448 from the vaginal and 448 from the cesarean section) were selected (Fig. 1).
Exclusion criteria
Mothers who had a preterm delivery, who lost her consciousness during/after giving birth, and/or who was unable to speak the Amharic language were excluded.
Variables of the study
Dependent variable
Mothers’ satisfaction of delivery care services.
Independent variables
Socio-demographic characteristics
Age, ethnicity, religion, marital status, educational status, occupation, residence, monthly income.
Obstetric related characteristics
Parity, planned current pregnancy, reason to visit the health facility, mode of delivery, fetal birth outcome, and ANC follow up.
Maternal delivery service related characteristics
Time spent to get health professionals, presence of waiting area, gender privacy during physical examination, maternal HIV status, mother’s health status after delivery, sex of the baby, the sex of the health professional, greeting during health care provision, respectful practice of professional during delivery, birth weight of the baby, and distance from the health facility.
Operational definitions
Satisfied
We took the Likert scale to measure the satisfaction status of mothers on delivery care services. Each satisfaction assessing question rated from 1 up to 5. Then, we sum up these ten variables altogether. Then, we computed the 75th percentile for the ten variables. Finally, those mothers who scored the value of 75th percentile or more of the satisfaction assessing questions were considered as satisfied of the delivery care services. However, mothers who scored less than the value of 75th percentile were considered as dissatisfied on the delivery care service [9].
Vaginal delivery
Vaginal delivery service encompasses spontaneous vaginal, forceps and vacuum delivery.
Data collection procedure and quality control
Data were collected using a structured questionnaire. The questionnaire was adapted from similar studies. The questionnaire consisted of questions about social-demographic, obstetric, health facility, the health provider and service delivery related questions (attached in the supplementary file portion). Questions related to delivery service satisfaction comprised 10 items with 5 scales Likert type (1- Very Dissatisfied, 2- Dissatisfied, 3-Neutral, 4- Satisfied, 5- Very Satisfied) Before the data collection, the questionnaire was translated into Amharic (national working language) by the independent translator (Ph.D. in linguistics) and then back to English to check for consistency. Finally, the Amharic version was used. The data collectors were two female BSc nurses working in non-selected health facilities and the supervisors were two female health officers working in a private medical college. Then, they took training for 2 days. Pre-test of the questionnaire was done on 85 of delivered mothers in two hospitals having dual delivery care services in the West Gojjam zone. The questionnaire was assessed for clarity, length, and completeness. Then, some adjustment was made in the questionnaire and extra briefing was made to the data collectors.
Then, the actual data were collected over 6 h of giving birth, and a similar questionnaire was administered to both modes of deliveries. The delivery service was assisted by using local (lidocaine) or regional/spinal (mainly bupivacaine) anesthesia.
The daily meeting was held between the principal investigator and the data collectors to detect any problems that had arisen. In addition, inspection for completeness and quality of data collection was carried out daily by supervisors and detailed feedback was provided to data collectors.
Data processing and analysis
The collected data were checked for completeness and consistency by the principal investigator. Then, they were cleaned, coded and entered into EPI- Data and exported into SPSS Version 20.0 for analysis. Descriptive statistics were computed and Logistic regression model was used to identify the association between explanatory and outcome variables. Adjusted Odds ratio (OR) with 95% CI was used to measure the strength of association between explanatory variables and the outcome variable. The model fitness was checked using Hosmer and Lemeshow goodness of fit (P > 0.05). A p-value < 0.2 at bivariate analysis was considered for variables to be candidates for multivariable logistic regression analysis. Variables with a p-value of < 0.05 at multivariate analysis were considered as statistically significant predictors of mothers’ satisfaction.
Ethics approval and consent to participate
Ethical approval was obtained from Research and Publication Office of GAMBY Medical and Business College, and the approval letter was obtained from the Amhara public health institute. The college ethics committee approved the procedure for verbal consent as the study is not a sensitive and privacy issue, rather assessing the satisfaction level of delivering mothers in the delivery services they got. The purpose of the study was explained to the respondents and verbal informed consent was obtained from them in the Amharic language. Confidentiality of information was maintained by omitting any personal identifier from the questionnaires. The study participant information sheet was attached to the front page of the questionnaire and before the actual data collection process, the participants were well informed and the data collection was on a voluntary basis. Because we obtained verbal consent, documentation of consent was not required. However, the information provided by each respondent was kept confidential in a secure place.
