Abstract
Purpose of study:
To analyse the bacteriological spectrum, identify most appropriate antibiotics for hand infections, and to characterize patterns and sites of hand infections. This information was collected against the background of a high prevalence of HIV infected patients and increasing antibiotic resistance.
Description of methods:
This was a prospective, cross-sectional, analytical study done on 66 patients presenting with hand infections at a public hospital from January to June 2009. A standardised treatment protocol was followed in managing these patients. Data was collected from each participant, and laboratory reports were followed up for the identity and antibiotic susceptibility of causative organisms. All patients were counselled for HIV status and consenting participants were tested.
Summary of results:
Staphylococcus aureus was the commonest isolate. Results show that Cloxacillin is still an effective first line antibiotic for community acquired hand infections in the absence of immunosuppression. Alternative empiric therapy would be Clindamycin – especially in the B-lactamase intolerant patient. HIV infection played a significant role in the bacteriology of hand infections with an increased incidence of polymicrobial and gram negative infections. Data regarding age, gender, types of infection, mechanism of injury, x-ray findings and laboratory values are also reported.
Conclusion:
Hand infections are common conditions that have significant morbidity. Referral is often delayed and infections present late. Immunosuppression seems to play a role in the bacteriology, the incidence of polymicrobial infections and the antibiotic sensitivity. Cloxacillin seems to be an adequate first line treatment for acute community acquired bacterial hand infections in immunocompetent patients in our institution, excluding human bites and farm yard injuries.
