Effect of a Pharmacist-led, Collaborative Practice on Clinical Outcomes in Persons With Diabetes
Diabetes is a complex chronic illness known for its high prevalence (11.3% in the United States), significant healthcare burdens in terms of cost and management, and high mortality rate (seventh leading cause of death in the United States in 2019). Diabetes-related complications including ischemic heart disease, stroke, hyperglycemic crises, amputations, and hypoglycemia accounted for 8.25 million hospital discharges and 25.9% of emergency department visits, contributing towards the $327 billion total cost of diabetes in 2017. Proper treatment of diabetes is integral to reduce a patient's risk of developing complications; however, a number of barriers can create additional burdens for persons with diabetes.
Several studies have also demonstrated reductions in hospitalizations and/or ED visits for patients enrolled in pharmacist-led collaborative practice models. While the literature as a whole clearly describes the impact of ambulatory pharmacist intervention in achieving guideline-based clinical goals (i.e., HbA1c, blood pressure), few studies have reported on adherence with guideline-driven pharmacotherapy pre- and post-pharmacist intervention, or on pharmacist impact in reducing medication burden.

Detailed Description
Diabetes is a complex chronic illness known for its high prevalence (11.3% in the United States), significant healthcare burdens in terms of cost and management, and high mortality rate (seventh leading cause of death in the United States in 2019). Diabetes-related complications including ischemic heart disease, stroke, hyperglycemic crises, amputations, and hypoglycemia accounted for 8.25 million hospital discharges and 25.9% of emergency department (ED) visits, contributing towards the $327 billion total cost of diabetes in 2017. Proper treatment of diabetes is integral to reduce a patient's risk of developing complications; however, a number of barriers can create additional burdens for persons with diabetes (PWD). The root of these barriers affecting diabetes care is a topic of significant discussion especially given the emergence of conversations surrounding social determinants of health (SDOH) in recent years. A 2019 article from Annual Review of Public Health suggests that PWD experience health disparity, which are preventable differences in quality of healthcare and outcomes. This article discusses that health disparity is largely due to SDOH which are defined as the economic, environmental, political, and social conditions in which people live. Unfortunately, published research thus far has not identified strategies to reduce diabetes-related health inequity across the entire population. When providers recognize and discuss non-medical factors that influence PWD's health outcomes (e.g., food security, housing stability, transportation access, and financial security), they are able to promote health equity within their practice. Realistically, many providers have limited time to devote to individual patient encounters which often focus on immediate medical issues and eclipse discussions of non-medical issues, pharmacotherapy, and lifestyle changes. Thus, multidisciplinary care teams, including dieticians, nurses, and pharmacists, are recommended by the American Diabetes Association's (ADA) Standard of Care in Diabetes to ensure PWD receive the comprehensive care they need.
Within these teams, ambulatory care pharmacists are uniquely equipped to utilize their strong background in pharmacotherapy to provide chronic disease state medication management services for core primary care disease states, such as diabetes, hypertension, and hyperlipidemia. In many settings, ambulatory care pharmacists work under collaborative practice agreements (CPA), which are legal arrangements between pharmacists and physicians that allow for expanded services. The additional abilities granted within CPAs allow clinical pharmacists to assume professional responsibility by performing patient assessments, counseling, and referrals; ordering laboratory tests; administering drugs; and selecting, initiating, monitoring, continuing, and adjusting drug regimens. By allowing pharmacists to take on this prescribing role within a multidisciplinary team, patients receive more individualized, patient-centered care as recommended by ADA's Standard of Care in Diabetes and there is reduced clinical inertia (i.e., lack of treatment intensification in a patient not at evidence-based goals for care). In fact, patients receiving care from pharmacists under CPA were shown to have significantly better outcomes compared to patients receiving "usual care" without pharmacist intervention. Studies in a variety of ambulatory settings have illustrated that pharmacist intervention can significantly improve clinical outcomes in terms of hemoglobin A1C (HbA1c) level, blood pressure control, lipid panels, and body mass index. One study of a pharmacist-driven type 2 diabetes mellitus (T2DM)-targeted collaborative practice in an urban underserved clinic demonstrated significant improvements not only in HbA1c and tobacco cessation but also in guideline recommended utilization of statins and angiotensin-converting enzyme inhibitor/angiotensin receptor blockers. Several studies have also demonstrated reductions in hospitalizations and/or ED visits for patients enrolled in pharmacist-led collaborative practice models. While the literature as a whole clearly describes the impact of ambulatory pharmacist intervention in achieving guideline-based clinical goals (i.e., HbA1c, blood pressure), few studies have reported on adherence with guideline-driven pharmacotherapy pre- and post-pharmacist intervention, or on pharmacist impact in reducing medication burden.
