Study Notes
Medication Adherence
- Adherence refers to how well a patient's behavior aligns with healthcare provider recommendations.
- Compliance specifically measures how well patients follow prescriber's advice.
- Treatment effectiveness relies significantly on both patient adherence and drug efficacy.
- Patient literacy is crucial for achieving adherence; cooperation from the patient is essential for optimal therapeutic outcomes.
Non-adherence
- Primary Non-adherence (Initiation): Involves patients failing to fill prescriptions and is associated with the initiation and refilling of medications.
- Secondary Non-adherence (Implementation): Occurs when patients do not take medications as prescribed, impacting clinical outcomes and healthcare costs.
Causes of Medication Non-adherence
- Patient-related factors: Age, gender, education, physical disabilities, cultural attitudes, economic factors, and severity of the disease.
- Doctor-related factors: Multiple drug regimens and poor patient-doctor interactions hinder adherence.
- Pharmacist-related factors: Lack of patient education and insufficient counseling.
- Health system-related factors: Issues such as long waiting times, uncaring staff, inaccessibility, and prescription-related problems including illegibility.
Role of Pharmacist in Patient Adherence
- Simplifying medication regimens by minimizing unnecessary drugs.
- Connecting dosing times to patients' daily routines.
- Providing thorough patient education using various teaching methods.
- Offering tools like medication calendars and reminder charts.
- Introducing improved dosage forms, such as transdermal patches.
- Ensuring follow-up for medication refills.
Methods to Measure Adherence
- Direct Methods: Involve observing therapy directly and detecting drugs/metabolites in body fluids, though these can be costly and may yield inaccurate results due to metabolic variations.
- Secondary Database Analysis: Utilizes patterns derived from prescription services or pharmacy claims for quantifying adherence.
Types of Secondary Database Metrics
- Medication Possession Ratio (MPR): Compares days' supply obtained against refill intervals.
- Dichotomous Variable: Uses arbitrary cutoffs for adherence measurement.
- Continuous, Multiple Interval Measures: Include cumulative measurement of days’ supply obtained over intervals.
- Continuous Single Interval Measures: Focus on specific intervals to assess medication acquisition and gaps.
- Pill Count Method: Calculates adherence based on the difference between dispensed dosage units and remaining units compared to prescribed amounts.
