Prevalence and treatment outcomes of skin infections among elderly population: a retrospective cross-sectional study

Abstract

Background

Geriatric population is increasing day by day throughout the world and there is a critical need to provide them the best health services including dermatological care due to their weakened immune system. The main objective of this study is to determine the prevalence and factors affecting the treatment outcomes of skin infections among elderly population.

Methods

A 5-year retrospective cross-sectional study was conducted at the Department of Dermatology, Hospital Pulau Pinang. Patients aged ≥65 years of age with confirmed diagnosis of skin infection were included in the study.

Results

A total of 455 patients were included and the most prevalent skin infections were eczema (27.6%) followed by dermatitis (13.8%), xerosis (13.8%), and bullous pemphigoid (8.8%). Cloxacillin (18%), Tetracycline (7.9%), and Unasyn (Ampicillin and Sulbactam) (5.7%) are the common antibiotics prescribed to treat skin infections. Age, alcohol consumption, polypharmacy, and presence of other co-morbidities are the most important factors that affected the treatment outcomes of skin infections among geriatrics.

Conclusion

Eczema is the most prevalent skin infection among the elderly population. Age, consumption of alcohol, usage of more than five medicines simultaneously, and presence of co-morbidities are the main factors that are involved in better treatment outcomes of skin infections among study population.
