Low-value care at the actionable level of individual health systems.
This study measured and reported low-value care use across and within individual health systems and to identify system characteristics associated with higher use using Medicare administrative data. This retrospective cohort study was conducted using 11,637,763 Medicare beneficiaries in 556 health systems in the AHRQ Compendium of US Health Systems. These Medicare beneficiaries were enrolled in Medicare Parts A and B for at least 12 months in 2016 or 2017. The most common low-value services include preoperative laboratory testing, prostate-specific antigen testing in men older than 70 years, and use of antipsychotic medications in patients with dementia. Forty-one low-value services were measured based on the Milliman MedInsight Health Waste Calculator. In multivariable analysis, the health system characteristics associated with higher use of low-value care were a smaller proportion of primary care physicians for systems with less than the median percentage of primary care physicians vs -0.16 for those with more than the median percentage of primary care physicians; no major teaching hospital without a teaching hospital vs -0.18 with a teaching hospital; larger proportion of non-White patients for systems with >20% of non-White beneficiaries vs -0.06 for systems with ≤20% of non-White beneficiaries; headquartered in the South or West for the South and 0.22 for the West compared with -0.09 for the Northeast and -0.44 for the Midwest;, and serving areas with more health care spending for areas above the median level of spending vs -0.24 for areas below the median level of spending.
