Cooper Z, Stiegman O, Ndumele CD, Staiger B, Skinner J. (2022). Geographical Variation in Health Spending Across the US Among Privately Insured Individuals and Enrollees in Medicaid and Medicare. JAMA Network Open, 5(7):e2222138. DOI:10.1001/jamanetworkopen.2022.22138.
Key Points. Questions: Is regional health care spending correlated with insurance type (ie, Medicare, Medicaid, and private insurance), are there regions that are low-spending across all 3 payers, and are similar factors correlated with regional spending by payer? Findings: In this cross-sectional study, there was a low correlation in regional spending across the payers, and only 3 regions were simultaneously in the lowest quintile of spending for each payer. There were no regional correlates of spending that went in the same direction and were significant across all payers. Meaning: These findings suggest that payer-specific strategies will likely be necessary to raise efficiency in the US health care system.
