Maternal Mortality in a Rural District of Pakistan and Contributing Factors.

INTRODUCTION

Pakistan is among the ten countries that account for 60% of global maternal mortality. Lack of accurate data on maternal mortality and a complex interrelation of access and quality of healthcare services, healthcare delivery system, and socio-economic and demographic factors contribute significantly to inadequate progress in reducing maternal mortality.

MATERIAL AND METHODS

A population-based prospective cohort study was conducted in a rural district of Pakistan using data obtained from an enhanced surveillance system. A total of 7572 pregnancies and their outcomes were recorded by 273 Lady Health Workers and 73 Community Health Workers over 2016-2017. Logistic regression was used to calculate the unadjusted and adjusted odds ratios (OR) for maternal mortality for each risk factor. Population Attributable Fraction (PAF) was derived from the ORs and risk factor prevalence.

RESULTS

The study recorded 18 maternal deaths. The maternal mortality rate was estimated at 238/100,000 pregnancies (95% CI 141-376), and the maternal mortality ratio was 247/100,000 live births (95% CI 147-391). Half of the maternal deaths (9) were from obstetric hemorrhage, and 28% (5) from puerperal sepsis. Postpartum hemorrhage was associated with a 17-fold higher risk of maternal mortality (PAF = 40%) and puerperal sepsis with a 12-fold higher mortality risk (PAF = 29%) compared to women without these conditions. Women delivered by unskilled birth attendants had a three-fold (PAF = 21%), and women having prolonged labour had a fourfold risk of maternal mortality compared to those with these conditions. Women with leg swelling (47%) and pre-eclampsia (26%) are at seven times the risk of maternal mortality compared to those without these conditions. Mortality in women delivered by unskilled birth attendants was three times higher than with skilled attendants.

CONCLUSION

The study, among a few large-scale prospective cohort studies conducted at the community level in a rural district of Pakistan, provides a better understanding of the risk factors determining maternal mortality in Pakistan. Poverty emerged as a significant risk factor for maternal mortality in the study area and contributes to the underutilization of health facilities and skilled birth attendants. Incorporating poverty reduction strategies across all sectors, including health, is urgently required to address higher maternal mortality in Pakistan. A paradigm shift is required in Maternal and Child health related programs and interventions to include poverty estimation and measuring mortality through linking mortality surveillance with the Civil Registration and Vital Statistics system. Accelerated efforts to expand the coverage and completeness of mortality data with risk factors to address inequalities in access and utilization of health services.
