Insights
Older adults with hypertension living with family and high blood pressure are at greater risk for poor medication adherence. Conversely, those without hypertension complications or falls show better adherence. This aids in identifying at-risk patients.
Area of Science:
- Gerontology
- Cardiovascular Medicine
- Pharmacology
Background:
- Hypertension is a prevalent chronic condition in older adults.
- Medication adherence is crucial for managing hypertension and preventing complications.
- Identifying risk factors for non-adherence is essential for improving patient outcomes.
Purpose of the Study:
- To investigate the factors associated with poor medication adherence in elderly hypertensive patients.
- To identify predictors of non-adherence to antihypertensive medications in this population.
Main Methods:
- A cross-sectional study design was employed.
- A self-report questionnaire assessed demographic characteristics and adherence using the Morisky Medication Adherence Scale.
- STROBE checklist guidelines were followed for reporting.
Main Results:
- Univariate analysis revealed associations between adherence and education, co-living, hypertension complications, admission blood pressure, and falls.
- Multivariable analysis identified living with spouse/offspring and high admission blood pressure as predictors of poor adherence.
- Absence of hypertension complications and falls were associated with lower risk of poor adherence.
Conclusions:
- Findings help identify older adults at high risk for poor medication adherence.
- Nurses can use this information for timely identification and intervention to improve medication management.
- Targeted interventions can be developed based on identified risk factors.
Aims:
To explore the risk factors for poor medication adherence in older people with hypertension.
Design:
A cross-sectional study.
Methods:
Participants were administered with a self-report questionnaire about their demographic characteristics; additionally, their four-item Morisky Medication Adherence Scale scores were calculated. The STROBE checklist was applied as the reporting guideline for this study (File S1).
Results:
Univariate analysis indicated that the following five factors were statistically significantly associated with medication adherence: education level (χ2 = 8.073, p = .045), co-living (χ2 = 11.364, p = .010), hypertension complications (χ2 = 10.968, p = .001), admission blood pressure (χ2 = 8.876, p = .003), and falls (χ2 = 6.703, p = .010). Multivariable binary logistic regression analysis showed that there were four statistically significant predictors, such as people who lived with spouses and offspring (OR = 3.004, p = .017), and those who had high admission blood pressure (OR = 1.910, p = .003) had a greater risk of poor medication adherence, whereas those without hypertension complications (OR = 0.591, p = .026) and those without falls (OR = 0.530, p = .046) had a lower risk.
Relevance To Clinical Practice:
We believe that these findings contribute to the identification of high-risk people with poor adherence, allowing nurses to identify people with poor adherence in a timely manner, and pay attention to the people's medication.
