The impact of health insurance expansion on physician treatment choice: Medicare Part D and physician prescribing.
Researchers tested the effect of the introduction of Medicare Part D on physician prescribing behavior using data on physician visits from the National Ambulatory Medical Care Survey (NAMCS). Subjects were patients aged 60-69. The researchers found a 32% increase in the number of prescription drugs prescribed or continued per visit and a 46% increase in the number of generic drugs prescribed or continued for the elderly after the introduction of Medicare Part D.

Changes in the equity of US health care financing in the period 2005-16.
This study examined changes in how households pay for health care spending in the United States from 2005 to 2016. At the start of the study period, households in the bottom 20% of income paid 26.8% of their income for health care compared to about half that amount for those with income in the top 1 percent. By 2016 the percentages had become about the same across all income levels. This result reflected increases in coverage through Medicaid and the Affordable Care Act Marketplaces.

The demand for preventive and restorative dental services among older adults.
This study examined the use of preventive and restorative dental services among older adults. Traditional Medicare does not have dental benefits, and older adults must either be employed, have post-retirement dental benefits or spousal coverage, or enroll in a Medicare Advantage program that includes dental coverage. The authors used 2007-2015 Medical Expenditure Panel Survey and supplemental data on dental care prices to estimate the demand for dental care. Dental service was not sensitive to out-of-pocket prices. Older adults with private dental insurance increased preventive service by 25%, and dental coverage through Medicaid increased basic and major service use by 23% and 36%. Women used dental insurance more than men.
