Improving Medication Adherence: Insights from Research
Medication Adherence in Older Adults: Effective Interventions
Meta-Analysis of Interventions
A comprehensive meta-analysis investigated the effectiveness of various interventions aimed at improving medication adherence (MA) among older adults. The study synthesized data from 33 randomized controlled trials, encompassing 11,827 participants. The results demonstrated that interventions significantly improved MA (effect size [ES] = 0.33), knowledge (ES = 0.48), and diastolic blood pressure (ES = 0.19).
Key Strategies for Enhancing Adherence
The analysis identified several strategies that were particularly effective in enhancing adherence. These included the use of special medication packaging, dose modification, participant monitoring of medication effects and side effects, succinct written instructions, and standardized interventions. Notably, larger adherence effects were observed when a moderate proportion of participants were women, for those taking 3-5 medications, and when adherence was measured by pill count.
Implications for Future Research
The findings underscore the importance of tailored interventions to improve MA in older adults. However, the considerable heterogeneity in the magnitude of effects across studies suggests a need for further empirical research to optimize these interventions.
Understanding Oral Contraceptive Pill Instructions: Challenges and Solutions
Complexity of Missed Pill Instructions
A systematic review evaluated patient understanding of oral contraceptive (OC) pill instructions, particularly related to missed pills. The review highlighted that instructions on managing missed pills are often too complex and confusing, lacking clear definitions and failing to account for variations in estrogen content.
Evidence from Studies
The review included nine studies, revealing that more women knew what to do after missing one pill compared to missing two or three pills. Additionally, women found it difficult to understand missed pill instructions contained in patient package inserts. However, providing written brochures with missed pill instructions alongside contraceptive counseling significantly improved knowledge on managing missed pills.
Effective Communication Strategies
The review found that graphic-based instructions were more effective than text-only instructions, and that less information resulted in better comprehension. Despite clear instructions, many women did not intend to follow the recommended actions, indicating a gap between understanding and adherence.
Conclusion
Improving medication adherence requires a multifaceted approach, particularly among older adults and users of oral contraceptives. Effective strategies include special packaging, dose modifications, and clear, concise instructions. Future research should focus on optimizing these interventions to address the diverse needs of patients and bridge the gap between understanding and adherence.
