Factors Associated with Reliance on Audio-Only Technology (Telephone) for Completion of Telepsychiatry Visits

Introduction: The ability to access telepsychiatry through audio-video technology versus audio-only (telephone) technology potentially leads to inequitable outcomes. This study examines the characteristics of patients who relied on the telephone to complete outpatient telepsychiatry visits in a large health system. Methods: This is a retrospective analysis of all telepsychiatry outpatient visits conducted from May 1, 2020, to December 31, 2021. Demographic, clinical, and socioeconomic factors were extracted from the electronic health record. Two-sample t tests were used for continuous variables and χ² tests for categorical variables for bivariate analyses. Multiple logistic regression was used to examine the association between only telephone visits and all input variables. Results: Eight hundred ninety-four (8.9%) patients completed all visits only by telephone during the study period. In bivariate analyses, factors associated with telephone-only visits included male sex, non-English primary language, Black race, unmarried status, non-Hispanic ethnicity, older age, Medicare enrollment, uninsured status, and higher social vulnerability index (SVI). Psychiatric diagnoses associated with only telephone visits included substance use disorders and psychotic disorders. In multivariate analyses, factors associated with higher odds of only telephone visits included older age, inactive patient portal, comorbid diabetes, higher SVI, and higher broadband adoption. Psychiatric diagnoses associated with higher odds of completing only telephone visits included psychotic disorders, substance use disorders, or intellectual/developmental disabilities. Conclusions: Several patient-level factors are associated with a reliance on the telephone to complete telepsychiatry appointments.
