Maternal deaths attributable to hypertensive disorders in a tertiary hospital in Ghana.

OBJECTIVE

To determine the contribution of hypertensive disorders of pregnancy to maternal deaths at Korle Bu Teaching Hospital (KBTH) in Accra, Ghana.

METHODS

The retrospective descriptive study conducted at KBTH during 2010-2011 involved a comprehensive review of all maternal deaths attributable to hypertensive disorders.

RESULTS

There were 21 385 deliveries, 21742 live births, and 199 maternal deaths, resulting in a maternal mortality ratio of 915.3 per 100000 live births. In total, 63 (31.7%) maternal deaths were attributable to hypertensive disorders with a case fatality rate of 3.9%. The incidence of hypertensive disorders of pregnancy was 7.6%. Hypertensive disorders were the most common direct cause of maternal death followed by obstetric hemorrhage (26.6%), unsafe abortion (11.1%), and puerperal sepsis (3.5%). Most (38.1%) hypertension-related maternal deaths occurred within 24hours of admission and the majority (79.4%) had been referred. Eclampsia was the leading immediate cause of hypertension-related death (23.8%), followed by acute renal failure (20.6%), intracerebral hemorrhage (15.9%), and pulmonary edema (12.7%).

CONCLUSION

Hypertensive diseases are the leading cause of maternal death at KBTH, having overtaken obstetric hemorrhage, with eclampsia, acute renal failure, intracerebral hemorrhage, and pulmonary edema representing the major immediate causes of hypertension-related maternal death.
