Insights
Coronary heart disease patients show poor adherence to enhanced external counter pulsation (EECP) after hospital discharge. Improving patient understanding and offering flexible scheduling are key to enhancing EECP treatment adherence.
Area of Science:
- Cardiology
- Rehabilitation Medicine
- Public Health
Background:
- Enhanced external counter pulsation (EECP) is part of cardiac rehabilitation for coronary heart disease (CHD) in China.
- Short hospital stays and unclear post-discharge adherence limit EECP effectiveness.
- This study addresses the low adherence to EECP post-discharge in CHD patients.
Purpose of the Study:
- To investigate adherence rates to EECP among CHD patients after discharge.
- To identify factors influencing EECP adherence in this population.
- To explore reasons for non-adherence to EECP treatment post-discharge.
Main Methods:
- A retrospective mixed-methods study combining quantitative and qualitative approaches.
- Quantitative analysis of 1,304 CHD patients treated with EECP (March 2020 - August 2021).
- Qualitative in-depth interviews with non-adherent patients to explore dropout reasons.
Main Results:
- Only 24.23% of patients adhered to EECP post-discharge.
- Predictors of non-adherence include shorter disease duration, lower education, longer travel distance, older age, female gender, and angina pectoris.
- Higher family income was associated with better adherence.
Conclusions:
- Post-discharge adherence to EECP for CHD is significantly low.
- Interventions like educational materials (brochures, videos) are needed to improve understanding of EECP importance.
- Flexible scheduling (off-hours, weekends) may improve adherence, particularly for younger patients.
Background:
Although enhanced external counter pulsation (EECP) has been included in the cardiac rehabilitation prescription for coronary heart disease (CHD) in China, because the total treatment duration of a course of EECP is 36-36 h, the average hospital stay of CHD patients is short, and the adherence after discharge remains unclear. The purpose of this study is to investigate the adherence to EECP in CHD patients after discharge, and analyze the related influencing factors.
Methods:
A retrospective mixed method study combining qualitative and quantitative methods. Quantitative component included CHD patients who had received EECP treatment between March 2020 and August 2021. The qualitative component included in-depth interviews with patients who did not adhere to EECP after discharge. Binary Logistic regression was used to analyze the predictors of EECP adherence after discharge. In-depth interviews with patients were conducted to explore the reasons for dropping out of the EECP after discharge.
Results:
Among 1,304 patients, only 24.23% adhered to EECP treatment after discharge. Binary logistic regression results showed that patients with disease duration < 2 years (OR = 3.13, 95%CI: 2.31-4.24), high school or below (OR = 2.81, 95%CI: 1.98-4.01), distance between residence and hospital more than 20km (OR = 2.08, 95%CI: 1.47-2.96), age over 60 (OR = 2.00, 95%CI: 1.46-2.74), female (OR = 1.64, 95%CI: 1.78-2.29), and angina pectoris (OR = 1.65, 95%CI: 1.16-2.34) were more likely to not adhere to EECP treatment after discharge. However, patients with monthly family income over 8000¥ (OR = 0.46, 95%CI: 0.28-0.75) were more likely to adhere to EECP treatment after discharge than those with household monthly income below 4,000¥. In the qualitative results, the reasons why patients do not adhere to EECP after discharge mainly include insufficient understanding, restricted objective conditions and psychosocial factors.
Conclusions:
The adherence of CHD patients to EECP treatment after discharge was poor. It is necessary to develop effective intervention measures, such as brochures or videos to improve patients' understanding of the importance of adherence to EECP treatment after discharge. In addition, offering EECP treatment during off-hours and weekends may also improve adherence in more young patients.
