Mortality Pattern of Hospitalized Surgical Patients in a Nigerian Tertiary Hospital

There is paucity of reports describing the pattern of surgical mortality in Nigeria. The aim of this study was to determine the incidence and pattern of mortality associated with surgical care in our hospital and to identify areas of improvement. The records of all patients who died after admission for surgical care at the Federal Medical Centre Makurdi between January 2009 and December 2011 were studied retrospectively. Data extracted were patients' demographics, surgical diagnosis, co-morbidity, surgical procedures performed, duration of hospital admission and outcome of treatment. Data were analyzed with SPSS version 17. There were 2,273 admissions into the surgical wards within the study period. During this period, there were 151 deaths with a crude mortality rate of 6.6 %. Ninety-four (62.3 %) patients were males and 57 (37.7 %) were females (M:F = 1.6:1). The age of the patients ranged from 8 days to 95 years with a mean age of 36.1 ± 20.1 years. Acute abdomen (37, 24.5 %), traumatic brain injury (32, 21.2 %) and malignancy (28, 18.5 %) were the commonest surgical diagnosis. Trauma-related deaths accounted for 48 (31.8 %) of all the deaths. Road traffic crash (89.6 %) was the commonest cause of injury. Surgical operations were performed in 75 (49.7 %) of the patients who died, while 76 (50.3 %) did not have any operative intervention. Mortality in patients admitted into the surgical ward was 6.6 %. Trauma-related death was the commonest. Traumatic brain injury, typhoid perforation of the bowel and malignancy were the leading causes of surgical death in our centre.
