[Morbidity and mortality related to obstetrical referral patients to the hospital of Bobo-Dioulasso, Burkina Faso].

Abstract

The obstetrical referral patients admitted to the Sanon Souro hospital in Bobo-Dioulasso (Burkina Faso) during 1991 were retrospectively reviewed. During the study period 741 women were admitted. The median distance between the referring centre and Bobo-Dioulasso was 33 km. Median age was 22 years and median parity was 3. Indications for referral were dominated by obstructed labour, haemorrhages and infections. The proportion of maternal mortality in the study was 5.4% and was not related to maternal age or parity. However, there was a linear trend of increasing mortality according to the distance between the referring centre and Bobo-Dioulasso (X2 for trend: 7.56; p = 0.006). The perinatal mortality rate of 420 p. thousand was not related to maternal age, but a parity exceeding 4 was a risk factor for the occurrence of perinatal death (relative risk: 1.4; 95% C.I.: 1.2-1.7). As for maternal mortality, there was a linear increase of perinatal mortality with the distance from the referring centre (X2: 20.8; p = 0.00001). There was no marked seasonal variation in the number of referrals nor in the mortality rates per month.
