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.

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.

Prevalence of potentially inappropriate medication use in older adults using the 2012 Beers criteria.
The purpose of this study was to use the most recently available population-based data to estimate potentially inappropriate medication (PIM) prevalence under the 2012 update of the Beers list of PIMs and to provide a benchmark from which to measure future changes. It found that despite the overall high use of PIMs, there has been a decline observed in recent years.

Dental use and expenditures for older uninsured Americans: the simulated impact of expanded coverage.
The purpose of this paper is to empirically determine if insurance alone would close the current gaps in dental use and expenditures between insured and uninsured older Americans. Comparing simulated dental use and expenditures rates of newly insured persons against the corresponding rates for those previously insured, the authors found that it would close previous gaps in use and expense.
