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.
