Behavioral Health Diagnoses and Health Care Use Before and During the COVID-19 Pandemic

Objective: Emerging evidence has suggested a population-wide worsening of psychiatric symptoms during the COVID-19 pandemic, particularly among individuals with preexisting mental health conditions. The authors investigated whether reported behavioral health problems are being identified and treated. Methods: This observational cohort study retrospectively compared Medicaid data of patients from the first year of the pandemic (2020) in the United States (N=1,589,111 patients) with the corresponding data from the year before (2019; N=1,715,872 patients). Outcome measures included several behavioral health diagnoses and health care utilization. Results: During the pandemic period examined, the numbers of patients served, adults receiving a new diag-nosis of anxiety, and children receiving a new diagnosis of depression all increased. Across all age groups, nonbe-havioral health emergency department visits significantly decreased. Conclusions: These findings support reports of increases in psychiatric morbidity but do not provide evidence for in-creased demand for health care services.
