Impact of a maternal and newborn health results-based financing intervention (RBF4MNH) on stillbirth: a cross-sectional comparison in four districts in Malawi

BMC Pregnancy and Childbirth, Volume 21, No. 1, Year 2021

Interpretação

Background: Malawi implemented a Results Based Financing (RBF) model for Maternal and Newborn Health, “RBF4MNH” at public hospitals in four Districts, with the aim of improving health outcomes. We used this context to seek evidence for the impact of this intervention on rates of antepartum and intrapartum stillbirth, taking women’s risk factors into account. Methods: We used maternity unit delivery registers at hospitals in four districts of Malawi to obtain information about stillbirths. We purposively selected two districts hosting the RBF4MNH intervention and two non-intervention districts for comparison. Data were extracted from the maternity registers and used to develop logistic regression models for variables associated with fresh and macerated stillbirth. Results: We identified 67 stillbirths among 2772 deliveries representing 24.1 per 1000 live births of which 52% (n = 35) were fresh (intrapartum) stillbirths and 48% (n = 32) were macerated (antepartum) losses. Adjusted odds ratios (aOR) for fresh and macerated stillbirth at RBF versus non-RBF sites were 2.67 (95%CI 1.24 to 5.57, P = 0.01) and 7.27 (95%CI 2.74 to 19.25 P < 0.001) respectively. Among the risk factors examined, gestational age at delivery was significantly associated with increased odds of stillbirth. Conclusion: The study did not identify a positive impact of this RBF model on the risk of fresh or macerated stillbirth. Within the scientific limitations of this non-randomised study using routinely collected health service data, the findings point to a need for rigorously designed and tested interventions to strengthen service delivery with a focus on the elements needed to ensure quality of intrapartum care, in order to reduce the burden of stillbirths. This was a quantitative cross-sectional study which used routinely collected hospital data in the referral hospitals serving the districts of Ntcheu, Dedza, Salima (Central region) and Thyolo (Southern region). These district hospitals provide a secondary level of care and serve as the referral hospitals for all the primary health centres in their respective districts. The RBF districts were purposively selected because of ready access to hospital records. The non-RBF comparison districts were randomly selected by applying a random number table to a list of Malawi districts. The primary outcome for analysis was stillbirth, defined as an infant born with no signs of life at or after 28 weeks gestation [13]. A power calculation to determine the sufficiency of the number of register records was performed using Open Epi version 3 resulting in a sample of 2800 with a power of 90%, at a statistical significance level of 5%. This was based on anticipated stillbirth rates of 15 per 1000 live births in the combined population of the intervention hospitals and 34 per 1000 in the combined population in the non-intervention hospitals. These assumptions were based on initial scrutiny of District Health Management Information System (DHIS-2) returns. Data were extracted from the registers which are used in maternity units to prepare routine monthly reports. Data collected included maternal age, gravidity (number of pregnancies), and gestational age in weeks, preeclampsia, low birth weight and stillbirths. We used assessment of gestational age and birth weight recorded in the registers following the routine practice of health facilities. In Malawi, most women do not undergo sonography to confirm gestational age. In these hospitals, weighing of the newborns is done by the midwives using routinely available hospital weighing scales. A prepared data extraction tool in the form of a register was used. Data were entered into Microsoft Excel and checked for accuracy, consistency, and completeness. Analysis was undertaken using STATA version 14. For continuous variables, means and standard deviations were considered and presented. Logistic regression models were developed to determine the odds ratio for stillbirth under intervention and non-intervention conditions, and to assess whether the statistical relationship was confounded by other factors. The possible confounders included in the multivariable models were; low birth weight, gestational age, gravidity and a diagnosis of pre-eclampsia, based on findings in two previous local studies [6, 7]. The study was approved on a waiver of the need for individual participant consent by the nationally mandated College of Medicine Research and Ethics Committee (COMREC) and administrative permission for access was granted by the Hospital authorities.
