Background: Population based mortality data are scarce
especially in developing countries including Nigeria.
Despite its limitations, hospital mortality analysis
assesses the quality of health-care delivery and provides
a proximate measure of mortality. We reviewed the
magnitude and causes of death among in-patients in a
tertiary hospital in northern Nigeria.
Methods: Analysis of mortality rate and causes of death
for the period 20052008 (inclusive) in Aminu Kano
Teaching Hospital. Causes of death were prospectively
entered on a database and classified according to the
International Classification of Diseases (ICD-10).
Results: Out of 51,975 patients admitted to the hospital,
4,029 of them died. This gives a mortality rate of 7.8%
(95% Confidence Interval of 7.5% to 8.0%). Specifically, of
the 15,484 males admitted, 2,361 died giving a mortality
rate of 15.2% while of the 36,491 females admitted, 1,668
died giving a mortality rate of 4.6%. The median age for all
patients that died was 32.4 years (range: less than 1 day
to 101 years), but 36.1 years (range: less than 1 day to
101 years) for the male and 29.3 (range: less than 1 day to
87 years) for the female subsets. The ten most common
causes of mortality were HIV/AIDS (8.3%), Septicaemia
(6.8%), cerebrovascular disease (6.3%), chronic renal
failure (3.9%) chronic liver disease (3.3%), diabetes
mellitus (3.2), neonatal jaundice (2.9%), severe birth
asphyxia (2.6%), prematurity (2.5%) and
bronchopneumonia (2.4%).
Conclusion: The mortality rate and causes of death are
comparable to similar centres. Regular mortality audits
could identify management errors and prevent recurrence
of avoidable deaths.
