Abstract

Background

Store-and-forward (SAF) teledermatology (TD) has the potential to increase access to timely, high-quality care for underserved populations. However, the cost-effectiveness of TD for underserved populations is uncertain.

Objective

This study evaluates the potential cost savings associated with a SAF TD program implemented for an underserved population in the city health clinics of urban Philadelphia.

Methods

We performed a retrospective analysis of SAF TD consultations for 700 outpatients managed in 12 Philadelphia primary care clinics. Primary care providers (PCPs) were asked to specify a treatment plan, as well as the type of care for the patient, in the absence of the TD service. Analysis compared cost of each patient case using the TD consult model versus conventional care.

Results

Twenty-seven percent (189/700) of in-person dermatology clinic visits and 3.29% (23/700) of emergency room (ER) visits were avoided using TD. Compared to conventional care, mean expected cost savings were $10.00-$52.65 per TD consult. In sensitivity analyses, these estimated savings remained positive across a range of parameters.

Limitations

The cost analysis relies on several assumptions regarding the cost of care, and indirect costs were not included.

Conclusion

Teledermatology can be a cost saving model while increasing access to dermatologic care.
