    Study Notes

    Defining Adherence

    • Compliance refers to the patient's actions mirroring the prescriber's recommendations.
    • Concordance emphasizes a collaborative discussion between the healthcare professional and the patient, where both agree on therapeutic decisions considering the patient's beliefs and preferences.
    • Adherence lies between compliance and concordance, acknowledging the patient's influence on their medication-taking.

    Importance of Adherence

    • Poor adherence limits the effectiveness of medications.
    • Non-adherence contributes to significant costs, both personally and for public healthcare systems.
    • Non-adherence is linked to an increased risk of hospital admissions due to medication-related issues.
    • Studies have shown a significant relationship between adherence and outcomes, with non-adherent patients in renal transplant cases experiencing higher rates of organ rejection or death compared to adherent patients.
    • Non-adherence can lead to worsening symptoms and overall health deterioration.

    Measuring Adherence

    • Adherence is often measured as a percentage of prescribed doses taken, considering both the number of doses taken and adherence to the prescribed schedule.
    • Defining adequate adherence rates varies across studies, with some aiming for 80% adherence, while others require higher levels, such as above 95% for medications like HIV drugs.
    • Adherence rates exist on a continuum, ranging from 0% to over 100%.

    Causes of Non-Adherence

    • Non-adherence is a multifactorial issue with two main categories:
      • Unintentional (involuntary): Often related to behavioral factors like forgetting to take medication.
      • Intentional (voluntary): Typically driven by cognitive factors like concerns about side effects.
    • Non-adherence is more prevalent in chronic conditions. For example, half of patients on statins discontinue their medication within six months of starting.

    Identifying Poor Adherence

    • Signs of poor adherence can include a patient not responding to treatment as expected.
    • Open communication with patients who may be collecting medication infrequently is crucial.
    • Approaching these conversations non-judgmentally can help patients feel comfortable discussing their adherence challenges.
    • Offering patients a comprehensive understanding of their medication's benefits and potential side effects can improve adherence.

    Direct Methods of Measuring Adherence

    • Direct methods are rarely used and are reserved for situations requiring strict adherence, like highly active anti-retroviral therapy (HAART) or anti-tuberculosis drugs.
    • Direct methods include:
      • Directly Observed Therapy: A healthcare professional directly observes the patient taking their medication.
      • Plasma Drug or Metabolite Measurement: Measuring the concentration of the drug or a breakdown product in the blood.
      • Biological Marker Measurement: Measuring the concentration of a marker added to the medication.
    • While direct methods offer precise measurements, they are expensive, burdensome for patients, and susceptible to manipulation.

    Indirect Methods of Measuring Adherence

    • Indirect methods are commonly used but may not accurately reflect true adherence, potentially overestimating adherence rates.
    • Examples of indirect methods include:
      • Patient Questionnaires/Self-Reports: Simple and inexpensive but prone to errors due to memory lapses or inaccurate reporting.
      • Pill Counts: Objective and quantifiable but susceptible to manipulation through pill dumping.
      • Prescription Refill Rates: Objective and easy to track but only reflect refills, not actual medication ingestion.
      • Assessment of Patient’s Clinical Response: Simple and easy but can be influenced by factors other than adherence.
      • Electronic Medication Monitors: Precise and quantifiable, allowing for tracking of patterns, but expensive and require follow-up visits to download data.
      • Measurement of Physiologic Markers: Easy to measure but can be affected by factors other than adherence.
      • Patient Diaries: Addresses recall limitations of other methods but may be altered by the patient.

    Medication Event Monitoring System (MEMS)

    • MEMS devices track how often a patient opens their medication container and provides insights into their adherence.

    Barriers to Adherence

    • Key barriers and their potential contributing factors:
      • Forgetfulness (30%): Complex medication regimens, other priorities.
      • Other Priorities (16%): Lack of consideration for patient lifestyle and cost of medication.
      • Decision to Omit Doses (11%): Lack of information about medication or condition.
      • Lack of Information About Medicines/Conditions (9%): Failure to thoroughly explain benefits and side effects.
      • Emotional Factors (7%): Emotional challenges impacting adherence.
      • No Reason Given (27%): Possible lack of a strong therapeutic relationship between the healthcare professional and the patient.

    Specific Challenges with Medication Adherence

    • HIV Treatment: Requires high adherence (at least 95%) to highly active anti-retroviral therapy (HAART).
    • Hypertension Treatment: The asymptomatic nature of hypertension and potential side effects of medication can hinder adherence.
    • Psychiatric Illness: High rates of non-adherence to antidepressants.

    Pharmacist's Role in Adherence

    • Education: Pharmacists play a vital role in educating patients about their medications, helping them understand their benefits, potential side effects, and proper administration.
    • Communication: Open and effective communication between the pharmacist and patient can facilitate a trusting relationship and encourage honest conversations about adherence.

    Factors Affecting Behaviour (COM-B Model)

    • The COM-B model is used to understand factors affecting behaviour change, in this case, improved medication adherence.
    • Key elements of the model:
      • Capability: Whether the patient has the physical and psychological ability to take their medication, including factors like opening containers, swallowing medication, and administering eye drops.
      • Opportunity: Factors outside the individual's control that impact their ability to adhere, such as access to transportation, the affordability of medication, and availability of support systems.
      • Motivation: Internal and external factors that influence a patient's desire to adhere to their medication regimen.

    Importance of Health Literacy

    • Health literacy is crucial for patients to manage their health effectively.
    • Limited health literacy:
      • Is associated with poorer overall health.
      • Can hinder adherence to medical regimens.
      • May reduce the use of health screenings.
      • Can lead to delayed diagnoses and presentation in later stages of disease.
      • May increase hospitalization rates.

    Two Key Elements of Health Literacy

    • Understanding health information: The ability to read, understand, and apply health information.
    • Communicating with healthcare professionals: The ability to effectively communicate health concerns and questions with healthcare professionals.

    Health Literacy in Healthcare Settings

    • Patients with limited health literacy often face challenges navigating healthcare systems, accessing information, and understanding instructions from healthcare providers.
    • They may have trouble:
      • Understanding medication labels
      • Following instructions for taking medication
      • Understanding appointment scheduling
      • Filling out forms
      • Advocating for their needs

    Health Literacy Statistics (European Health Literacy Survey 2019-21)

    • Across participating countries: 46% of the population had either inadequate or problematic health literacy.
    • Ireland: 43% of the population had inadequate or problematic health literacy.

    Literacy and Mortality Risk

    • Studies have found a correlation between limited health literacy and increased mortality risk.
    • Patients with limited health literacy experience a steeper decline in health over time.
