Surgical operations performed at Ombo Hospital in Western Kenya from J
anuary to December 1989 were studied and annual surgical rates were ca
lculated based on the estimated catchment area population. The total a
nnual rate of major surgery at this church-supported hospital was 207
operations per 100 000 people. This rate is similar to those at other
East African hospitals while rates in industrialized countries are 20-
35 times higher. The most common major procedures were Caesarean secti
on, laparotomy, hernia repair and salpingectomy. The 1989 rate of mino
r operations at the hospital was 1286 per 100 000 people with tooth ex
traction, wound suture, incision and drainage, evacuation of the uteri
ne cavity and closed reduction of fracture as the most frequent proced
ures. Major operations were performed exclusively by doctors while min
or surgery was carried out mainly by clinical officers, nurses and oth
er auxiliary staff.
