Introduction: Cost-effectiveness analyses help policymakers make informed decisions regarding funding allocation of health care resources. Cost-effectiveness analysis of technology-enabled models of health care delivery is necessary to assess sustainability of novel online, patient-centered health care models. Objective: We sought to compare cost-effectiveness of conventional in-office care with a patient-centered, online model for follow-up treatment of patients with psoriasis. Methods: Cost-effectiveness analysis was performed from a societal perspective on a randomized controlled trial comparing a patient-centered online model with in-office visits for treatment of patients with psoriasis during a 24-week period. Quality-adjusted life expectancy was calculated using the life table method. Costs were generated from the original study parameters and national averages for salaries and services. Results: No significant difference existed in the mean change in Dermatology Life Quality Index scores between the two groups (online: 3.51 ± 4.48 and in-office: 3.88 ± 6.65, P value =.79). Mean improvement in quality-adjusted life expectancy was not significantly different between the groups (P value =.93), with a gain of 0.447 ± 0.48 quality-adjusted life years for the online group and a gain of 0.463 ± 0.815 quality-adjusted life years for the in-office group. The cost of follow-up psoriasis care with online visits was 1.7 times less than the cost of in-person visits ($315 vs $576). Limitations: Variations in travel time existed among patients depending on their distance from the dermatologist's office. Conclusion: From a societal perspective, the patient-centered online care model appears to be cost saving, while maintaining similar effectiveness to standard in-office care.
