Study Notes

Medication Adherence

  • Compliance refers to patient behavior matching the prescriber's recommendations.
  • Concordance involves a two-way exchange between the healthcare professional and patient, incorporating the patient's views and preferences, leading to shared therapeutic decisions.
  • Adherence is the patient's actions meeting the prescriber's recommendations or expectations, taking into account the patient's beliefs, preferences, and prior knowledge.
  • Non-adherence limits the benefits of medicines, resulting in significant personal and public costs.
  • Approximatley 30% (some sources suggest up to 69%) of drug-related hospital admissions are due to non-adherence.
  • In renal transplant patients, 91% of non-adherent patients experienced organ rejection or death, compared to 18% of patients who adhered to their medication regimen.
  • Adherence measurement is expressed as the percentage of prescribed doses taken or the percentage taken at the correct time.
  • Adequate adherence rates vary: some clinical trials aim for 80%, while others aim for over 95%, especially for medications like HIV drugs.
  • Adherence rates are on a continuum from 0% to over 100%.

Non-Adherence

  • Non-adherence is multifactorial, with two main categories:
    • Unintentional (involuntary) or behavioral (forgetting)
    • Intentional (voluntary) or cognitive (concerns about side effects)
  • Non-adherence is more prevalent in chronic conditions.
  • For example, 50% of patients on statins discontinue their medication within 6 months of starting treatment.

Measuring Adherence

  • Indirect methods are most commonly used, but they may overestimate adherence due to potential misrepresentation.
  • A combination of methods maximizes accuracy.

Indirect Adherence Measurement Methods

  • Patient questionnaires and self-reports:
    • Simple and inexpensive.
    • Susceptible to error due to memory lapse, leading to inaccurate results.
  • Pill counts:
    • Objective, quantifiable, and easy to perform.
    • Can be inaccurate due to pill dumping.
  • Prescription refill rates:
    • Objective and easy to monitor.
    • Does not guarantee medication ingestion.
    • Requires a closed pharmacy system.
  • Assessment of patient's clinical response:
    • Simple and easy.
    • Factors other than adherence can affect outcomes.
  • Electronic medication monitors:
    • Precise, quantifiable results with pattern tracking.
    • Expensive and requires return visits to download data.
  • Physiological marker measurements (e.g., heart rate):
    • Easy to measure.
    • Factors other than adherence can influence results.
  • Patient diaries:
    • Helps correct poor recall for other indirect methods.
    • Easily altered by the patient.

Medication Event Monitoring System

  • An objective method to measure adherence.
  • The system tracks the time and date the patient opens the medication container, providing data on medication use.
  • Patients on prophylactic treatments are less likely to be adherent compared to those on active treatments.

Adherence Support from Pharmacists

  • Practical strategies focus on addressing the patient's:
    • Capability to adhere to the medication regimen (COM-B model).
    • Motivation to adhere to the medication regimen.

Clinical Decision Aids - Statins

  • Clinical decision aids are tools that help patients and prescribers make informed decisions about medication use.
  • These aids are often used for treatments with potential risks or side effects.
  • For statins, clinical decision aids might address the potential risks and benefits of medication, helping patients understand the potential consequences of adherence or non-adherence.
  • NICE (National Institute for Health and Care Excellence) provides clinical decision aids for statins.

Health Literacy

  • Health literacy is defined as the cognitive and social skills that enable individuals to access, understand, and use health information to make informed health decisions.
  • Personal health literacy refers to an individual's ability to find, understand, and use health information.
  • Organizational health literacy focuses on healthcare organizations' ability to provide accessible and understandable information to their patients.
  • People with lower health literacy:
    • May report poorer overall health.
    • Have lower adherence to medical regimens.
    • Are less likely to use screening services.
    • Present in later stages of disease.
    • Are more likely to be hospitalized.

Two Elements of Health Literacy

  • Functional health literacy: refers to basic reading and writing skills.
  • Critical health literacy: involves the ability to analyze and interpret health information.

Health Literacy and Patients

  • When patients access health services, they need health literacy skills to:
    • Find and understand information about their health conditions.
    • Communicate effectively with healthcare professionals.
    • Make informed decisions about their care.

Health Literacy Statistics

  • The 2019-2021 European Health Literacy Survey found that 46% of participants across all countries had inadequate or problematic health literacy.
  • In Ireland, this figure is 43%.

Literacy and Mortality Risk

  • Lower health literacy is strongly associated with increased mortality risk.
  • Inadequate health literacy can be a stronger indicator of mortality risk than years of schooling.

Approaches to Health Literacy

  • Universal precautions approach: Aims to ensure all patients receive information in an accessible way and have a good baseline level of support.
  • Health literacy tool shed: Offers resources and tools for improving health literacy.

Knowing Your Audience

  • Consider:
    • Culture and language.
    • Emotions and cognition.
    • Hearing loss.
    • Vision problems.
    • Literacy levels.
    • Older adults.
    • Children and youth.

Signs of Low Health Literacy

  • Possible signs include:
    • Asking for information already displayed in writing.
    • Unwillingness to approach the front desk or counter.
    • Uneasy body language and facial expressions
    • Confusion about illness, medication dosage, and timings.
    • Giving excuses to avoid reading or writing.
    • Reluctance to fill out forms, stopping after name and address.
    • Not filling out forms completely.
    • “My wife looks after that."
    • Responding with “Subtle cues in language.”
    • Not responding to “teach back” techniques.

Health Literacy Approaches

  • Verbal:

    • Use clear and concise language.
    • Avoid jargon.
    • Repeat important information.
    • Use teach-back techniques to ensure understanding.
  • Visual:

    • Use visual aids to illustrate information.
    • Ensure images are culturally appropriate and easy to understand.
    • Limit the amount of text on each page.
    • Use large font sizes.
  • Written:

    • Use plain language and simple sentence structure.
    • Keep materials short and to the point.
    • Use bullet points and headings to make information easy to scan.
    • Provide information in multiple formats (e.g., print, audio, video).
