Insights
Nurse-led chronic disease management significantly improved medication adherence and blood pressure control in hypertension patients. This approach enhances treatment compliance and patient outcomes.
Area of Science:
- Cardiology
- Pharmacology
- Public Health
Context:
- Hypertension management requires consistent pharmacological treatment adherence.
- Chronic disease management programs are crucial for long-term patient care.
- Assessing adherence and identifying influencing factors is vital for effective hypertension control.
Purpose:
- To evaluate the effectiveness of a nurse-led chronic disease management program on pharmacological treatment adherence in hypertension patients.
- To identify variables associated with improved adherence to antihypertensive medications.
- To assess the impact of enhanced adherence on blood pressure control.
Summary:
- A 17-month longitudinal study of 283 hypertension patients (mean age 73.4 years, 62.5% women) utilized nurse-led interventions including telephone advice and home visits.
- The program resulted in a significant increase in treatment adherence (25.1% to 85.5%) and a decrease in blood pressure (p<0.05).
- Adherence was higher in patients with hypertension and chronic renal failure, and those on angiotensin-converting enzyme inhibitors, but lower with angiotensin receptor blockers (p<0.05).
Impact:
- Nurse-performed chronic disease management strategies effectively increase adherence to antihypertensive treatments.
- Improved adherence contributes to better blood pressure control, thereby reducing morbidity in hypertensive patients.
- This model demonstrates a successful intervention for enhancing medication compliance and health outcomes in a chronic disease population.
Objective:
This study assessed pharmacological treatment adherence using the Morisky-Green Test and identified related variables.
Method:
A longitudinal and retrospective study examined 283 patients with hypertension (62.5% women, 73.4 [10.9] years old) who were being monitored by a chronic disease management program for 17 months between 2011 and 2012. Nurses performed all the actions of the program, which consisted of advice via telephone and periodic home visits based on the risk stratification of the patients.
Results:
A significant increase in treatment adherence (25.1% vs. 85.5%) and a decrease in blood pressure were observed (p<0.05). Patients with hypertension and chronic renal failure as well as those treated using angiotensin-converting enzyme inhibitors were the most adherent (p<0.05). Patients with hypertension who received angiotensin receptor blockers were less adherent (p<0.05).
Conclusions:
Strategies such as nurse-performed chronic disease management can increase adherence to anti-hypertensive treatment and therefore contribute to the control of blood pressure, minimizing the morbidity profiles of patients with hypertension.
