Abstract
Background: The issue of nosocomial infection constitute
a significant burden on any health care facility particularly
in resource constrained centers of many developing
countries.
Objectives : A prospective cross sectional study was
designed to determine the baseline surgical site infection
rate following abdominal surgeries, determine the
influence of various factors on infection rates, evaluate
the predictive value of the ASA, SENIC, NNIS indices on
infection rates and identify the common aerobic and
anaerobic organisms responsible for such infections .
Methods: One hundred and forty four consecutive patients
who had abdominal surgeries were studied at the Lagos
University, Teaching Hospital over a one year period .
Demographic, clinical and other parameters were obtained
with aid of a proforma. Those who developed surgical site
infection had swabs taken for aerobic, anaerobic cultures
and antimicrobial sensitivity .
Results: Wound infection rate was 17.40/o. Surgeries
involving the small bowels and the colon made up 75o/o of
all infected cases. The predominant organisms isolated
were Pseudomonas, enterobacter, proteus species
Bacteroides was the most frequently isolated anaerobic
organism. The predictive factors for infection were long
surgeries, surgical procedures classified as contaminated
or dirty, high ASA(American society of Anaesthesilogist)
scores, SENIC(Study of Efficacy of Nosocomial Infection
control), NNIS( National Nosocomial Infection
Surveillance index) scores.
Conclusion: The predictive scores can be utilized to
identify high risk surgeries and institute appropriate
measures to reduce surgical site infections.
