Diabetes Medication Adherence

Understanding the Challenges to Improve Health Outcomes

What is Medication Adherence?

Simply put, medication adherence means taking medications correctly. It is the extent to which patients take medication as prescribed by their doctors. Taking medication correctly incorporates several different aspects, including:

  • Getting prescriptions filled
  • Understanding the medications’ directions
  • Taking the correct dosage
  • Taking medication at the right frequency
  • Being persistent and consistent with taking medication

For people living with diabetes, medication adherence is a critical aspect of managing the condition and living healthier lives.

Positive Clinical Outcomes

The most important outcome of increased medication adherence is, of course, healthier people with improved qualities of life. But the benefits of diabetes medication adherence can also be seen across the health system, from medical professionals to insurance providers to the pharmaceutical and device industries.

  • Adherence is linked to positive clinical outcomes
  • Adherence can lead to lower per-patient costs as positive health outcomes increase
  • Low adherence leads to increased morbidity and mortality
  • Low adherence is associated with greater risk of major adverse cardiac event

Non-Adherence

Nonadherence is not as simple as patients choosing not to take their medications. There is a difference between nonintentional and intentional nonadherence. Many different factors, including socioeconomic factors, health care system factors, and medical comorbidities, can all impact adherence. Non-adherence can take several different forms:

  • Initiation: the individual fails to fill their prescription or begin their treatment
  • Implementation: the patient doesn’t take the medication as prescribed (delayed or incorrect dosages), making the medication then appear ineffective
  • Persistence: The individual starts out taking their medication, but eventually discontinues their treatment 
Estimated $637 billion revenue is lost globally by pharmaceutical companies due to medication non-adherence. (Source).

Diabetes Medication Adherence Statistics

Various studies on diabetes medication adherence show the true scope of the issue. The following diabetes medication adherence statistics help to provide a context through which to view the impact of noncompliance.

Barriers to Adherence

Each individual faces unique barriers when it comes to diabetes medication adherence. Understanding those barriers enables the entire health system—from medical professionals to insurance providers to the pharmaceutical industry—more easily help patients overcome those barriers. Here are some of the most common barriers to medication adherence faced by diabetes patients.

Lack of acceptance of the diagnosis

People who are struggling to accept their diabetes are much less likely to initiate and adhere to their medication. There are many reasons why someone may initially not accept their diabetes diagnosis. Here are some common reasons for a lack of acceptance:

  • The person is asymptomatic or rarely experiences symptoms.
  • The person is not educated about diabetes.
  • They feel a loss of independence and ability to live life on their terms, so they simply decide to live as if they do not have diabetes.

Feeling fearful or overwhelmed

Another common emotion patients experience after receiving a diabetes diagnosis is fear. The fear can take many shapes, including:

  • Fear of the unknown—what is going to happen to me?
  • Fear of managing their condition
  • Fear of administering their medication or checking their blood sugar levels
  • Fear of increased doctor visits
  • Fear of side effects
Feeling fearful or overwhelmed

Incorrect perceptions of condition or medication

Often, general practitioners who don’t specialize in diabetes don’t have the time or training to properly educate patients on their condition. This can lead the patient to develop misconceptions about their disease.

One common misconception is that insulin only needs to be taken when the person is experiencing symptoms or when their blood tests raise a red flag. Patients may gauge the necessity of treatment based on their perception of their current state, rather than following the recommendations of a health professional.

While fear or denial can play a role in this pattern, a more common challenge is the patient not fully understanding either the prescription instructions or the purpose of the medication they are taking.

Struggling with financial resources

Diabetes is a disease that disproportionately affects low-income individuals. At the same time, diabetes self-management presents some of the biggest challenges for people who struggle with financial resources.

A low-income status affects nearly every aspect of diabetes self-management. Low-income individuals may not always have reliable access to their medications. Other potential barriers that can affect adherence include food insecurity, lack of access to safe and affordable exercise, and low health literacy.

Struggling with financial resources

Literacy or language barrier

High-risk populations of diabetes patients may face barriers of comprehension when it comes to adhering to their medication. Low literacy or a language barrier with a care provider can lead to a lack of understanding of the importance of medication and how it affects diabetes management, including:

  • Purpose of the medication
  • Prescribed dosage amounts and timing
  • Medication identification: differentiating between different medications and their functions
  • Reducing/skipping doctor or pharmacy visits (feeling that the lack of understanding makes these visits pointless)

Challenges with lifestyle changes

When faced with a life-altering diagnosis, it can often be difficult to accept that certain lifestyle changes need to be made to properly manage the condition. Many diabetes patients struggle with changing their diets and exercise habits when first faced with the diagnosis. This challenge also extends to taking their medication. It can be difficult for a newly diagnosed diabetes patient to incorporate a new daily medication regimen into their routine, and get used to keeping the necessary supplies with them at all times.

Access to care

For a variety of different reasons, many people living with diabetes struggle with access to the necessary care to properly manage their conditions. Lack of access to care can include:

  • Lack of availability of services
  • Prohibitive healthcare and prescription costs
  • Lack of patient mobility
  • Difficulty getting to the doctor or pharmacy

How to Increase Diabetes Medication Adherence

Clearly, the issue of medication adherence for people living with diabetes is deep, complex, and multifaceted. The most important thing for anyone within the healthcare system to bear in mind is that diabetes medication adherence isn’t only a metric or statistic to be tracked and monitored; it affects real people living in the world every day—people with hopes, fears, goals, and challenges who are struggling to manage a chronic illness.

Medication adherence is most challenging for at-risk and underserved populations. These are the people who face the most barriers when it comes to adherence for diabetes medication.

Approximately 50% of patients do not take their medications as prescribed (Source).

Achieving positive health outcomes requires more than education; it requires deep behavioral and mindset changes. But as we have seen, making these changes is challenging for a wide variety of reasons. Only through the caring experience of human connection can underserved diabetes populations begin to self-manage their conditions.

Certified Diabetes Educators

Certified Diabetes Educators (CDEs) are health professionals who work one-on-one with patients to help identify their personal barriers and teach strategies for overcoming them. CDEs educate, support, and advocate for people affected by diabetes, as well as promote self management to achieve individualized behavior and treatment goals.

CDEs can help people living with diabetes in many ways. Successful self-management involves a broad range of topics, and it is the CDE’s goal to identify the key areas for improvement facing each individual. CDEs can help individuals focus on:

  • Medication
  • Nutrition
  • Exercise
  • Coping skills

With a personalized approach, people living with diabetes can become empowered to improve their lives and achieve measurably improved health outcomes.
