Profile, Bacteriology, and Risk Factors for Foot Ulcers among Diabetics in a Tertiary Hospital in Calabar, Nigeria

Abstract EN

Diabetic foot disease is a major medical, social, and economic problem.

This retrospective study assessed the profile of diabetes mellitus patients with foot ulcers in the University of Calabar Teaching Hospital (UCTH), Nigeria.

Admission records of all patients admitted unto the medical wards of UCTH over a 5 year period were analysed.

The records of diabetic patients were retrieved.

Data on patient characteristics and possible risk factors for diabetes mellitus foot ulcers was extracted.

Of the 3,882 patients admitted, 297 (7%) were on account of complications of diabetes mellitus.

Foot ulcers accounted for 63 (21.2%) of all diabetic admissions.

The elderly constituted the majority of patients admitted with foot ulcers.

The average duration of stay of diabetics with foot ulcers was 38.5 days.

Diabetics admitted for other conditions had average duration of admission of 15.8 days.

Staphylococcus aureus was the commonest organism isolated from swabs of foot ulcers.

Most of the organisms identified from ulcer swab cultures were sensitive to quinolones and resistant to penicillins.

These diabetic foot ulcers were significantly associated with peripheral sensory neuropathy, peripheral vascular disease, intermittent claudication, and walking barefoot.

An effective diabetes foot programme is required to address these risk factors and reverse the current trend.
