Processes and outcomes of diabetes mellitus care by different types of team primary care models.
This study compared processes and outcomes of care provided to older patients with diabetes by primary care teams composed of only primary care physicians (PCPs) versus team care that included nurse practitioners (NPs) or physician assistants (PAs). The authors studied 3,524 primary care practices identified via social network analysis and 306,741 patients aged 66 and older diagnosed with diabetes mellitus in or before 2015 from Medicare data. Outcomes looked for was more adherence to guideline-recommended care including eye examination, hemoglobin A1c test, and nephropathy monitoring. Preventable hospitalizations and high-risk medication prescribing rates were also measured. Patients in the team care practices received more guideline-recommended diabetes care than patients in PCP only teams. Patients in team care practices had a slightly higher likelihood of being prescribed high-risk medications. The likelihood of preventable hospitalizations was similar among all types of practices.

Regional supply of medical resources and systemic overuse of health care among Medicare beneficiaries.
The goal of this study was to explore health care system factors associated with regional variation in overuse of resources, as measured by the Johns Hopkins Overuse Index (JHOI). Medicare fee-for-service claims data from beneficiaries age 65 was used to calculate the JHOI for 306 hospital referral regions in the U.S. Regions with a higher density of primary care physicians had a lower JHOI, which indicates less systemic overuse. Regional characteristics associated with higher JHOI included the number of acute care hospital beds per 1000 residents and number of hospital-based anesthesiologists, pathologists, and radiologists. The authors conclude that regional variations in health care resources are associated with the level of systemic overuse of health care, and that the role of primary care doctors in reducing overuse deserves further attention.
