A 5 - year surveillance of wound infections at a rural tertiary hospital in Nigeria.
BACKGROUND
Wound infections are associated with increased morbidity and mortality.


OBJECTIVE
To determine the prevalence, aetiology and susceptibility profile of bacterial agents of wound infection among in- and- out patients at a rural tertiary hospital in Nigeria, within a 5 year period.


METHODS
Wound swabs collected from 156 out-patients and 353 in-patients were, cultured and microbial isolates identified using standard methods. Antibiotic susceptibility testing was done on bacterial isolates.


RESULTS
The prevalence of wound infection in 2006, 2007, 2008, 2009 and 2010 was 71.4%, 76.2%, 74.5%, 61.5%, and 67.0% respectively. The overall prevalence of wound infection was 70.1%. In all the years studied, out-patients had a higher prevalence of wound infection, but this was significant in 2007, 2009, and 2010 only. Staphylococcus aureus was the most prevalent pathogen in both in- and out - patients with the exception of 2009 where both Staphylococcus aureus and Pseudomonas aeruginosa had the same prevalence (24.4%) among in - patients. The flouroquinolones were the most potent antimicrobial agents against bacterial isolates from both in - and out -patients.


CONCLUSIONS
Staphylococcus aureus was the most predominant etiologic agent of wound infection among in and out patients. A generally higher resistance pattern was observed among nosocomial bacterial pathogens. Prudent use of antibiotics is recommended.
