A Cross-Sectional Study on the Occurrence of Maternal Mortality in Some Selected Hospitals in Kumasi Metropolis Using Zero-Inflated Negative Binomial

Background: Maternal mortality is one of the most devastating and emotionally distressing occurrences that can be experienced by a family or society. The objective of the study was to investigate the risk factors associated with maternal mortality across the various sub-metros using zero-inflated models.Methods: The study used secondary data obtained from eight health facilities within Kumasi metropolis from 2018 to 2022. The zero-inflated negative binomial (ZINB) is useful when dealing with count outcomes that show greater variability than would be expected in a standard Poisson distribution, a phenomenon known as overdispersion.Results: The maternal mortality rates (MMRs) for 2018 to 2022 were 427.53, 385.68, 284.21, 323.74, and 440.78 per 100,000 live births, respectively, in the Kumasi metropolis. The study found unsafe abortion, sepsis, tuberculosis, hemorrhage, and hypertension to be significantly associated with maternal mortality.Conclusion: We recommend a continuous health education campaign to encourage pregnant women to seek prompt medication when they suspect sepsis, hypertension, tuberculosis, and hemorrhage. Also, awareness about the risk associated with unsafe abortions should be promoted.
