Abstract
Background: Acute Intestinal
Obstruction (AIO) is a common life
threatening emergency in all general
hospitals all over the world. This study
provides a population based incidence of
acute intestinal obstruction derived from
hospital data within a period of seven
years preceding the year of the study
(2008/9). Inpatient records can provide
a fairly accurate data on the incidence of
acute intestinal obstruction since almost
all the cases are admitted in hospitals.
Objectives: This study aims at
determining the incidence and other
epidemiological characteristics of
AIO in Uasin Gishu County based on
the hospital records and the national
population census.
Methods: The study was conducted in
twelve hospitals (six within Uasin Gishu
County) and six from the surrounding
counties. Patient records for seven
years preceding the period of study
(2008) were retrieved and demographic
information of the disease and treatment
outcome (mortality) were analyzed
against the projected population for the
seven year period covered by the study
(2001-2007). The population projections
(the denominators) were based on Kenya
population census and housing survey,
1999.
Results: There were 444 cases of AIO
from Uasin Gishu County during the
seven year period of the study (2001-
2007). There were 319 males (71.8%)
and 125 females (28.1%) (male/female
ratio =2.6/1). The mean age was 31.4
years and the median age was 29 years.
The population of Uasin Gishu County
(1999 census) on which the population
growth projections was based was
622,705. Mean annual incidence for the
seven year period was 8.8 per 100,000
persons and this was significantly related
to age and gender (p-values = 0.0001).
Recovery (survival) rate was 93.5% and
mortality (case fatality) rate was 6.5%.
Mortality rate was not significantly
related to age and gender (p-value>0.05).
Conclusion: The observed annual
incidence of acute intestinal obstruction
in Uasin Gishu County was very low
compared to available global data. Our
findings could be a pointer to the general
burden of AIO in Kenya (given the
similarity of Uasin Gishu County and rest
of the country in relation to demography,
infrastructure and the state of health
care services). The incidence increased
exponentially with age. A prospective
population based study on incidence
could shed more light and confirm the
low incidence found in this study.
