BackgroundHome telehealth (HT) services have rapidly expanded in the Veterans Health Administration (VHA), but little is known about the real-world impact of the expansion of these services on utilization.ObjectiveTo evaluate the impact of expanding HT diabetes services in VHA on high-cost utilization.DesignThis cohort study used cross-temporal propensity score matching to identify patients with diabetes who would receive HT services (treatment group) with program expansion (treatment group) with a comparison group of patients with diabetes who did not receive HT services (control group) between 2010 and 2018. A difference-in-differences design was used to compare pre-post changes in high-cost utilization between propensity-matched groups. Data used was from the VHA's Corporate Data Warehouse.ParticipantsVHA patients with diabetes, n=7214 in the treatment group who received HT services, and n=1,067,138 in the control group who did not receive HT services.Main Measure(S)Emergency department (ED) visits, all-cause hospitalization, and hospitalizations for ambulatory care sensitive conditions (ACSCs).Key ResultsIn the baseline period, patients in our sample had a mean age of 67 years old (SD=11 years), were 97% male, and 78% had a hemoglobin A1c (HbA1c) < 8%. The increase in HT use was associated with a net increase of ED visits per patient (0.215 95% CI [0.152, 0.279]), all-cause hospitalization (0.053 95% CI [0.032, 0.074]), and ACSC hospitalization (0.032 95% CI [0.019, 0.045]).ConclusionsExpanding HT or remote monitoring services may lead to additional needs being identified for patients, including increased access to in-person care, such as ED or hospital services.© 2024.
