Abstract [en]

To study the decision-making model behind how physicians making prescribing decisions, we studied the effects of the introduction of Medicare Part D in 2006 on numbers and characteristics of medications prescribed by physicians. We identified a significant increase in overall number of medications prescribed due to Medicare Part D but did not find any effects on the number of antibiotics. The result suggests there exist factors distinguishing antibiotics from other medications that led to a change in incentives to prescribe antibiotics, such as costs of antibiotics resistances. . We also identified the heterogeneity responses to Medicare Part D with respect to physician’s employment status, primary care relationship and patient’s gender and diagnostic categories.
