Diagnostic agreement between a primary care physician and a teledermatologist for common dermatological conditions in North India

Abstract

Background:

Primary care physicians (PCPs) encounter a large number of patients with dermatological diseases. However, delivering appropriate management is a challenge considering the inadequate dermatology training offered during the undergraduate medical curriculum. Teledermatology is the clinical evaluation of skin lesions by dermatologists and allows patients to be diagnosed and treated from a distant site. It is seen as a potential solution to the shortage of specialists and providing equitable service in remote areas.

Aim:

The study was aimed at estimating the diagnostic agreement of common dermatological conditions between a PCP and a teledermatologist.

Materials and Methods:

Consecutive patients with dermatological ailments who attended a primary health care clinic were recruited into the study, examined by the PCP and offered a diagnosis. The clinical images and patients’ history were collected and transferred to a dermatologist at a tertiary center who also made a diagnosis. Agreement between diagnosis made by the PCPs and the teledermatologist was measured using kappa (κ) statistics.

Results:

Overall agreement between the diagnoses made by a PCP and the dermatologist was found to be 56%. Poor κ agreement (<0.4) was seen in the diagnosis of psoriasis and eczema.

Conclusion:

Teledermatology can supplement specialist dermatology service in remote areas. There was poor agreement in the diagnosis of psoriasis, classifying various types of eczematous conditions and fungal infections. Scarce manpower in dermatology at the primary health care level compounded by the burden of skin ailments necessitates training of PCPs in common dermatological conditions.
