Differences in Telemedicine Use Between People With and Without an Intellectual or Other Developmental Disability During the COVID-19 Pandemic

Abstract

Telemedicine utilization of people with an Intellectual or Other Developmental Disability (IDD) during the COVID-19 Pandemic is not well known. This study compares telemedicine utilization of those with and without IDD prior to the pandemic to after it began. Using the Utah All Payers Claims Database from 2019 to 2021, the study identified telemedicine utilization of adults aged 18 to 62 years old in 2019. Propensity score matching was used to minimize observed confounders of subjects with and without IDD in 2019. Negative binomial regression was used to identify factors that were associated with telemedicine utilization. The final number of subjects in the analysis was 18 204 (IDD: n = 6068, non-IDD: n = 12 136 based on 1:2 propensity score matching). The average (SD) age of the subjects was 31 (11.3) years old in 2019. Forty percent of the subjects were female, about 70% of subjects were covered by Medicaid in 2019. Average (SD) number of telemedicine use in 2020 (IDD: 1.96 (5.97), non-IDD: 1.18 (4.90); P < .01) and 2021 (IDD: 2.24 (6.78) vs 1.37 (5.13); P < .01) were higher for the IDD group than the non-IDD group. The regression results showed that the subjects with IDD had 56% more telemedicine encounters than those in the non-IDD group (Incidence Rate Ratio (IRR) = 1.56, P < .01). The growth of telemedicine during the COVID-19 pandemic has the potential to reduce persistent healthcare disparities in individuals with IDD. However, quality of telemedicine should be considered when it is provided to improve health of subjects with IDD.
