PBMs and pharmacists have the same goals when it comes to chronic disease management: reducing adverse events, improving medication adherence, achieving better quality outcomes, and ultimately, reducing costs for their payer-customers.
Diabetes management sits at the heart of these goals as one of healthcare’s greatest challenges. The reality is that approximately 50% of all drug errors involve insulin, according to the U.S. Pharmacopeia Medication Errors Reporting Program. The costs in the United States alone are staggering—$176 billion annually to treat more than 29.1 million patients.
For many pharmacists and PBMs, this statistic probably comes as no surprise, as they see the complexities of daily insulin management—a task that rests primarily with patients. Patients try to make the right dosage calculations, but the reality is that more than 97% of insulin overdoses occur at home, opening the door to adverse drug events (ADEs) and hospitalizations. In fact, fear of making a mistake is one of the primary causes of noncompliance with insulin therapies. One study reveals that only 60% of patients with type 2 diabetes take their prescribed medications.
Both pharmacists and PBMs are challenged in their present roles to have a positive impact on insulin management. Pharmacists at the counter can talk to patients when they pick up their medications and initiate follow-up calls to assess side effect and adherence. But without the right tools, they simply don’t have enough information to help patients circumvent adverse events.
In the same way, PBMs can reach out to health plans to ensure the right brand of insulin is chosen to match the insurance formulary, but ensuring proper day-to-day dosing is just too burdensome. Additionally, while many pharmacists at a PBM may have the skill and knowledge to adjust medications, they often lack the authority to direct patients to optimal medication choices. And even if they have the authority to adjust medications, without the proper engagement from patients, these clinical pharmacists are left without the necessary data to make informed decisions.
The good news is that telemedicine tools can improve this outlook by providing a real-time feedback loop that empowers patients to follow treatment plans correctly. Even better, these same tools allow clinical pharmacists to track that data in real time—including glucose levels, insulin doses, and adherence rates. These advanced solutions not only help patients successfully self-manage their condition and promote patient engagement, but also enable clinical pharmacists to intervene with their patients, effecting positive behavior changes and dosage titrations that lower, but maintain, healthy A1c levels.
Understanding the Insulin Challenge
Effective management of diabetes requires that providers and patients continually monitor the condition and address the various facets that alter insulin levels. For instance, s patient must calculate each insulin dose based on current blood sugar, the time of day, food that will be consumed or activity performed. If the calculation is inaccurate, the result could lead to further deterioration (hyperglycemia) or an ADE (hypoglycemia).
Many patients struggle to self-manage their condition and make less-than-optimal choices that lead to daily fluctuations in glucose levels. Left to their own devices to calculate the correct insulin dose, industry statistics reveal that up to 50% of patients forget instructions given to them. Physicians and pharmacists know how to do it, but for patients, it’s a hefty responsibility.
Insulin doses can be adjusted frequently based on an aggregate of previous days’ glucose values, by “dialing in” to the right dose or carbohydrate ratio. If clinical pharmacists provided through a PBM stay connected to patient data, they can easily determine the right insulin dose. That’s where telemedicine tools can help. By leveraging technology to translate complex dosing regimens into simple instructions using real-time feedback, patients know what to do in the moment. The challenge for PBMs is finding which tools actually deliver, then determining how best to allocate limited resources, such as time and personnel.
