Economic evaluations of videoconference and telephone consultations in primary care: A systematic review.

INTRODUCTION

Telehealth services using videoconference and telephone modalities have been increasing exponentially in primary care since the coronavirus pandemic. The challenge now is ensuring that these services remain sustainable. This review investigates the cost-effectiveness of videoconference and telephone consultations in primary care settings, by summarizing the available published evidence.

METHODS

A systematic search of PubMed, Embase, Scopus, and CINAHL databases was used to identify articles published from January 2000 to July 2020, using keyword synonyms for telehealth, primary care, and economic evaluation. Databases were searched, and title, abstract, and full-text reviews were conducted. Article reporting quality was assessed using the Consolidated Health Economic Evaluation Reporting Standards checklist.

RESULTS

Twenty articles were selected for inclusion, with 12 describing telephone triage services, seven describing telehealth substitution services, and one describing another telehealth service in primary care. These services were delivered by nurses, doctors, and allied health clinicians. Of the 20 included studies, 11 used cost analyses, five used cost-minimization analyses, and four used one or more methods, including either a cost-consequence analysis, a cost-utility analysis, or a cost-effectiveness analysis.

CONCLUSIONS

Telephone and videoconference consultations in primary care were cost-effective to the health system when deemed clinically appropriate, clinician when time was used efficiently, and when overall demand on health services was reduced. The societal benefits of telehealth consultations should be considered an important part of telehealth planning and should influence funding reform decisions for telehealth services in primary care.
