They are accessible to patients, help identify risk factors, provide lifestyle education, and offer medication management.

Diabetes affects about 30.3 million individuals in the United States, according to the CDC’s most recent estimate.1,2 In addition, the CDC estimates that among people aged 18 and older, about 84.1 million have prediabetes, a condition characterized by blood sugar levels higher than normal but not high enough for a diabetes diagnosis (eg, fasting plasma glucose, 100-125 mg/dL; glycated hemoglobin [A1C], 5.7%-6.4%).1,2 Individuals with prediabetes are also more prone to heart disease, stroke, and type 2 diabetes (T2D).

Diabetes, a group of diseases characterized by high blood sugar, is the seventh-leading cause of death in the United States, and complications from uncontrolled diabetes can also cause gum and kidney disease, vision loss, and peripheral diabetic neuropathy, potentially resulting in foot problems.2 Comorbid conditions, such as heart disease and stroke, are also more common in people with diabetes.

The American Diabetes Association (ADA) recommends a team-based approach to managing a patient’s diabetes.3 Findings from many studies back up the contributions that clinical pharmacists make as part of

the interdisciplinary team treating patients with diabetes.4-7

In particular, the Asheville Project highlighted the effectiveness of pharmacists in diabetes management. After 1 year, participants had significantly reduced their A1C and low-density lipoprotein cholesterol levels, a reduction that was sustained 5 years later.4 To piggyback on the success of the Asheville Project, the American Pharmacists Association (APhA) Foundation established the Diabetes 10-City Challenge as a program for communities and employers to fight diabetes and manage health care costs.5

COST BENEFIT

The results of a US Department of Veterans Affairs (VA) study found that getting patients with T2D to their A1C goal cost between $115 and $164, which is a small expense with a big payoff, considering that the estimated 3-years savings per patient to the VA hospital was $9000.8 The Asheville Project and Diabetes 10-City Challenge have also shown great cost benefit, with the latter saving about $918 per employee in health care costs during the first year of implementation.4,5 There are other cost benefits when metrics such as A1C, blood pressure (BP), and low-density lipoprotein levels improve.7

HOW PHARMACISTS CAN CONTRIBUTE

Accessibility

Despite heavy workloads and short staffing, pharmacists are available to answer patient questions, for counseling, and to dispense medications. Because of these frequent patient encounters, pharmacists are likely to see many people with prediabetes and can be instrumental in the education and screening process.

Identifying Risk Factors

As part of their accessibility in clinics, in the community, and during hospital rounds, pharmacists can help with risk-factor assessment, whether it is asking about family history, physical inactivity, and weight, and work with health care providers to obtain BP and cholesterol panels.

Lifestyle Education

Not only can pharmacists effectively counsel on specific diabetes medications, they can also educate patients on lifestyle modifications and other facets of diabetes management.6,9 For example, the ADA emphasized in its 2019 guidelines how technology is continually expanding and that self-monitoring of blood glucose is extremely important, especially among patients on insulin therapy.3 Pharmacists can help patients set up their glucometers, explain to them the importance of not having expired test strips, and help them develop a log to monitor their blood glucose.

Counseling on diet, exercise, and smoking cessation and helping select appropriate therapy for each individual can benefit clinics and community settings.6 And following up with these patients regularly can help eliminate or mitigate the adverse effects (AEs) caused by uncontrolled diabetes.

Medication Management

For patients with a new diagnosis, administering insulin, managing their diet and medications, and taking their blood sugar can be an overwhelming process. Strategies for staffing should be in place to ensure that pharmacists are available to assist patients and that no pharmacist is too busy filling prescriptions to answer questions and provide the necessary care and education for patients with diabetes. Medication nonadherence is a common issue, because of the complexity and lifelong nature of therapy and should frequently be discussed at visits.6 Patients on insulin need to be counseled on insulin storage, the signs and symptoms of hyper- or hypoglycemia, technique, and what to do in case of an event. Routine counseling on AEs, drug interactions, and duplicate therapy should also be a mainstay of care.

Monitoring

A large part of managing the adherence of patients and the effectiveness of treatment is monitoring. Daily logs for patients on insulin are important, as is measuring their A1C and other markers that can contribute to comorbid conditions, such as cholesterol and high BP. In clinics where pharmacists have collaborative practice agreements, they can work with a team to obtain and utilize these numbers. Clinical pharmacists in hospitals can discuss this on rounds, and community pharmacists can educate patients about the importance of showing up to their follow-up visits.

Prevention Screening

Not every diabetes case is textbook. Some cases are not revealed until a patient presents in an emergency state. A routine screening at a health clinic or pharmacy may be an efficient way to identify patients with a potential diagnosis among those with risk factors. A blood glucose draw, a referral to a physician, or a risk-factor assessment test are all methods by which this can be done. Social barriers should also be assessed when screening to determine if patients have the financial stability to afford medications, to ensure that they have healthy food available, and to see if they have community support.

Quality Improvement

Along with costs, many government programs focus on value-based care and outcomes as conditions. Because value-based care, along with reimbursement, is so important to patient care, clinical pharmacists can be a valuable resource in achieving quality and cost benchmarks.6,10

Transitions of Care

Reconciling medications through the discharge process and health care transitions ensures that duplicate therapy is eliminated and medications that were discontinued are not reordered. Pharmacists can follow patient care through physician visits, using clinical expertise to manage and monitor diabetes care plans, and educate on adherence, disease, and lifestyle.10

AVAILABLE RESOURCES

The National Diabetes Prevention Program (DPP) is a partnership of private and public organizations working together to build the infrastructure for the nationwide delivery of an evidence-based lifestyle program to delay or prevent the onset of T2D in adults with prediabetes.10 This program is based on the science of the DPP research study and several others, which found that making small behavioral changes helped people with prediabetes to lose 5% to 7% of their body weight and reduced their risk of developing T2D by 58%.10 Other resources for pharmacists include a certificate program set up through the APhA and becoming a certified diabetes educator.

CONCLUSION

The value added by having a pharmacist on the care team, whether in the clinic or in a community pharmacy, is significant. It is important for those leading diabetes programs—in a clinic, community, or hospital—to move beyond the traditional product focus of pharmacy services and recognize and integrate pharmacists into this important role.

With the prevalence of diabetes rising in the United States, increasing patient access to health care providers who can facilitate improved diabetes self-management is important. Pharmacists are a significant resource, and adding them to diabetes care teams can improve the outcomes of patients with diabetes, as well as prevent complications and reduce costs.

There is often a limited understanding of the services and value that pharmacists provide. It is important to take the time to educate providers and staff members about the certifications, educational background, and postgraduate training that allow pharmacists to operate in their unique role. This education, along with cost-analysis, could be paramount in creating new positions for pharmacists in clinics and other settings.
