Medicare Part D Prescription Trends for Antipsychotics (2013-2023)

A recent study in JAMA Network Open from the University of Texas Health Science Center at Houston highlights a significant shift in Medicare Part D prescription trends for antipsychotics from 2013 to 2023. Notably, while prescriptions from psychiatrists and primary care physicians declined annually by 3.2% and 2.6% respectively, advanced practice nurses and physician assistants experienced an 11.8% yearly increase. This suggests evolving roles in the healthcare provider landscape.

The study detailed declines in prescriptions from psychiatrists (48.4% to 32.4%) and primary care physicians (33% to 23.8%), contrasted by a rise from advanced practice clinicians (13.8% to 39.6%). These changes are possibly due to psychiatrist shortages and an 8% Medicare opt-out rate within the specialty. While total antipsychotic claims grew from 22.4 million to 24.1 million, the rate per enrollee decreased from 0.63 to 0.46, possibly impacting payer strategies and regulatory compliance.

Furthermore, the study did not explore specific prescribing patterns or compare the prescribing tendencies of nonphysician clinicians with physicians. However, it notes the expanded roles for nonphysician clinicians, particularly in nursing homes, where 15% of Medicare enrollees over age 75 receive antipsychotics, a noteworthy figure compared to the 3% of community-dwelling adults. These trends may influence future practices in risk management and care delivery within the insurance sector.
