Virtual Care Expansion and Physician Follow-Up Among Youth With First Mental Health Contact Through a Hospital: Population-Based Repeated Cross-Sectional Study

Le résumé fourni par la source

BACKGROUND: Timely follow-up is crucial for youth whose first mental health contact is through a hospital; virtual care could facilitate this. OBJECTIVE: This study aimed to examine the association between the significant expansion of virtual care in Ontario, Canada, and follow-up mental health care rates for these youths. METHODS: We conducted a population-based repeated cross-sectional study using linked health administrative databases. We identified first-contact emergency department (ED) visits or hospital admissions for self-harm, mood disorders, or psychosis from March 1, 2009, to February 29, 2024, among Ontario youth (aged 10-24 years). Virtual care was expanded in March 2020; we examined 2 expansion stages (temporary and permanent). Autoregressive integrated moving average analyses estimated level and slope changes (vs before virtual care) in age- and sex-standardized monthly rates of 7-day mental health follow-up. Subgroup analyses examined rurality and socioeconomic status. RESULTS: We identified 42,208 first-contact ED visits and 17,701 first-contact hospital admissions. Pre-virtual care mean follow-up rates were 17.64 (SD 2.97) per 100 first-contact ED visits and 21.90 (SD 5.05) per 100 first-contact hospital admissions. Temporary expansion was associated with immediate increases in follow-up that declined (level changes: 4.81, 95% CI 2.82-6.81 for ED visits and 7.51, 95% CI 4.41-10.60 for hospital admissions; slope changes: -0.31, 95% CI -0.42 to -0.21 for ED visits and -0.32, 95% CI -0.48 to -0.15 for hospital admissions). Permanent expansion was associated only with an immediate decrease in ED visit follow-up (level change: -3.81, 95% CI -6.70 to -0.92) that was significant in rural (-1.06, 95% CI -1.93 to -0.184) but not urban (0.44, 95% CI -0.179 to 1.06) areas; results were otherwise similar between subgroups. CONCLUSIONS: Virtual care was not associated with sustained changes or equity improvements in mental health follow-up for high-acuity youth, representing a missed opportunity to extend physician reach and address barriers. Further research and quality improvement are needed.
