AbstractThe COVID-19 pandemic led to a significant disruption, then recovery, of health care services use. Prior research has not examined the relative rates of resumption of high-value and low-value care. We examined the use of 6 common low-value services that received a D grade from the US Preventive Services Task Force compared with clinically comparable high-value services in a large commercially insured population nationwide from before the pandemic to April 1, 2021. We found that, overall, low-value services and high-value services were disrupted similarly. In aggregate, low-value care declined to 56.2% and high-value care to 53.2% in the initial month of the pandemic (April 2020) relative to baseline (number of visits in 2019 normalized by relevant enrolled population), then rebounded to 83.1% of baseline for low-value services and 95.0% of baseline for high-value services by January 2021. Substantial heterogeneity appeared across clinical contexts, such as prostate cancer screening for men 70 years and older rebounding to 111.8% of baseline and asymptomatic chronic obstructive pulmonary disease screening remaining at 38.5% of baseline in January 2021. This suggests that although, on average, resuming lower-value services may have been perceived to be a lesser priority by providers and patients, the pandemic may have had heterogeneous effects on consumer and provider decision-making along the dimension of clinical value. This enhances our understanding of how disruptions affect the relationship between clinical value and usage of different services and suggests the need for more targeted interventions to reduce low-value care.
