Utilization and Costs by Primary Care Provider Type: Are There Differences Among Diabetic Patients of Physicians, Nurse Practitioners, and Physician Assistants?

OBJECTIVE: The objective of this study was to compare health care utilization and costs among diabetes patients with physician, nurse practitioner (NP), or physician assistant (PA) primary care providers (PCPs). RESEARCH DESIGN AND METHODS: Cohort study using Veterans Affairs (VA) electronic health record data to examine the relationship between PCP type and utilization and costs over 1 year in 368,481 adult, diabetes patients. Relationship between PCP type and utilization and costs in 2013 was examined with extensive adjustment for patient and facility characteristics. Emergency department and outpatient analyses used negative binomial models; hospitalizations used logistic regression. Costs were analyzed using generalized linear models. RESULTS: PCPs were physicians, NPs, and PAs for 74.9% (n=276,009), 18.2% (n=67,120), and 6.9% (n=25,352) of patients respectively. Patients of NPs and PAs have lower odds of inpatient admission [odds ratio for NP vs. physician 0.90, 95% confidence interval (CI)=0.87-0.93; PA vs. physician 0.92, 95% CI=0.87-0.97], and lower emergency department use (0.67 visits on average for physicians, 95% CI=0.65-0.68; 0.60 for NPs, 95% CI=0.58-0.63; 0.59 for PAs, 95% CI=0.56-0.63). This translates into NPs and PAs having ~$500-$700 less health care costs per patient per year (P<0.0001). CONCLUSIONS: Expanded use of NPs and PAs in the PCP role for some patients may be associated with notable cost savings. In our cohort, substituting care patterns and creating similar clinical situations in which they practice, NPs and PAs may have reduced costs of care by up to 150-190 million dollars in 2013.

Impact Of Physicians, Nurse Practitioners, And Physician Assistants On Utilization And Costs For Complex Patients.

Because of workforce needs and demographic and chronic disease trends, nurse practitioners (NPs) and physician assistants (PAs) are taking a larger role in the primary care of medically complex patients with chronic conditions. Research shows good quality outcomes, but concerns persist that NPs' and PAs' care of vulnerable populations could increase care costs compared to the traditional physician-dominated system. We used 2012-13 Veterans Affairs data on a cohort of medically complex patients with diabetes to compare health services use and costs depending on whether the primary care provider was a physician, NP, or PA. Case-mix-adjusted total care costs were 6-7 percent lower for NP and PA patients than for physician patients, driven by more use of emergency and inpatient services by the latter. We found that use of NPs and PAs as primary care providers for complex patients with diabetes was associated with less use of acute care services and lower total costs.

Building Capacity in a Rural North Carolina Community to Address Prostate Health Using a Lay Health Advisor Model.

Background Prostate cancer is a critical concern for African Americans in North Carolina (NC), and innovative strategies are needed to help rural African American men maximize their prostate health. Engaging the community in research affords opportunities to build capacity for teaching and raising awareness. Approach and Strategies A community steering committee of academicians, community partners, religious leaders, and other stakeholders modified a curriculum on prostate health and screening to include interactive knowledge- and skill-building activities. This curriculum was then used to train 15 African American lay health advisors, dubbed Prostate Cancer Ambassadors, in a rural NC community. Over the 2-day training, Ambassadors achieved statistically significant improvements in knowledge of prostate health and maintained confidence in teaching. The Ambassadors, in turn, used their personal networks to share their knowledge with over 1,000 individuals in their community. Finally, the Ambassadors became researchers, implementing a prostate health survey in local churches. Discussion and Conclusions It is feasible to use community engagement models for raising awareness of prostate health in NC African American communities. Mobilizing community coalitions to develop curricula ensures that the curricula meet the communities' needs, and training lay health advisors to deliver curricula helps secure community buy-in for the information.
