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.

Digoxin use and associated adverse events among older adults.
The authors describe national-level trends of digoxin use, hospitalizations for toxicity, and subsequent outcomes over the past two decades. They found that, while digoxin prescriptions have decreased, the drug is still widely prescribed. However, the rate of hospitalizations for digoxin toxicity and adverse outcomes associated with these hospitalizations have decreased. They concluded that these findings reflect the changing clinical practice of digoxin use, aligned with the changes in clinical guidelines.

Trends in testosterone prescribing for age-related hypogonadism in men with and without heart disease.
A study in 2010 (Basaria et al) revealed more cardiovascular events in men randomized to take testosterone than among men receiving a placebo. By 2015 the FDA had revised testosterone labels to highlight lack of efficacy evidence and possible increased cardiovascular risk. This study examines trends in testosterone use among Medicare-insured men over the age of 50 with and without coronary artery disease (CAD). A random sample was used of Medicare fee-for-service recipients from January 1, 2007 to December 31, 2016 using prescription fills under Medicare Parts B and D. Results showed that testosterone use was consistently higher among men with CAD than for men without CAD. Prescription rates had lowered after the warnings in 2013 but has remained higher than in 2007 and was largely off-label.
