Successful lifestyle modification in older patients with coronary artery disease: results from the RESPONSE-2 trial

Introduction

Interventions to reduce lifestyle-related risk factors (LRFs) such as overweight, physical inactivity and smoking are effective in the secondary prevention of cardiovascular events. However, evidence of the effects of lifestyle-related secondary prevention programmes in older patients with coronary artery disease (CAD) is less conclusive than in younger patients.

Purpose

To compare the treatment effect on lifestyle-related risk factors (LRFs) in older (≥65 years) versus younger (<65 years) patients with CAD in The Randomised Evaluation of Secondary Prevention by Outpatient Nurse SpEcialists 2 (RESPONSE-2) trial.

Methods

The RESPONSE-2 trial was a community-based lifestyle intervention trial (N=824) comparing nurse-coordinated referral to a comprehensive set of three lifestyle interventions (physical activity, weight reduction and/or smoking cessation) to care as usual. The primary outcome was the proportion of patients with improvement at 12 months follow-up (N=711) in at least 1 LRF (without deterioration in the other LRFs). In the current analysis, we assessed if the overall beneficial treatment effect of the RESPONSE-2 intervention varied by age.

Results

At baseline, older patients (n=245, 69.2±3.9) had significantly more serious cardiovascular risk profiles and comorbidities (hypertension, diabetes mellitus and peripheral artery disease) than younger patients (n=579, 53.7±3.9). The overall treatment effect did not vary by age (OR overall 1.67, 95% CI 1.22 - 2.31). However, older patients were more likely to achieve ≥5% weight loss (OR old 5.58, 95% CI 2.77–11.26 vs. OR young 1.57, 95% CI 0.98 - 2.49, P interaction=0.003) and younger patients were more likely to show non-improved individual LRFs (OR old 0.38, 95% CI 0.22–0.67 vs. OR young 0.88, 95% CI 0.61–1.26, P interaction=0.01).

Conclusion

Despite more serious cardiovascular risk profiles and comorbidities among older patients, nurse-coordinated referral to community-based lifestyle interventions was at least as successful in improving LRFs in older as in younger patients. Higher age alone should not be a reason to withhold lifestyle interventions in patients with CAD.

Video-based tools to enhance nurses' geriatric knowledge: A development and pilot study

BACKGROUND

The need for health care professionals with geriatric knowledge is expected to increase due to aging of society. Educational tools that fit the specific learning styles of nurses and nursing students might be useful for this. Serioussoap.nl (available in Dutch and English) is an educational tool that integrates video-based gaming and storytelling, and it might be an effective way to improve the geriatric knowledge of nurses or nursing students.

OBJECTIVES

To investigate the effect of Serioussoap.nl on the geriatric knowledge of nurses and nursing students, and to evaluate its usability.

DESIGN

We conducted a development and an explorative pilot study, using a pretest posttest quantitative design to investigate the effect of Serioussoap.nl on geriatric knowledge. A qualitative approach was used to evaluate its usability.

PARTICIPANTS AND SETTING

Three vocational nursing schools (n = 119 second/third year students), one baccalaureate nursing university (n = 77 first year vocational nurses) and one home-care organization (n = 44 vocational nurses) in the Netherlands participated in the quantitative study, and 94 vocational students participated in the qualitative study.

METHODS

We measured the effect on geriatric knowledge with the Knowledge of Older People Questionnaire (KOP-Q, score 0-30). The qualitative study included observations of 94 participants while they played Serioussoap.nl, four semi-structured focus groups and eleven individual interviews.

RESULTS

The study demonstrated a significant increase of geriatric knowledge of 7.8% (+2.3 score on the KOP-Q, 95% Confidence Interval (1.4-3.2, p < 0.001). The qualitative data showed that Serioussoap.nl contributed to the reflective learning-style and enhanced meaningful learning.

CONCLUSION

Serioussoap.nl increased the students' geriatric knowledge and was perceived as a suitable and effective educational tool for vocational nursing students and nurses.

Readmission and mortality in patients ≥70 years with acute myocardial infarction or heart failure in the Netherlands: a retrospective cohort study of incidences and changes in risk factors over time

Objectives

To determine the risk of first unplanned all-cause readmission and mortality of patients ≥70 years with acute myocardial infarction (AMI) or heart failure (HF) and to explore which effects of baseline risk factors vary over time.

Methods

A retrospective cohort study was performed on hospital and mortality data (2008) from Statistics Netherlands including 5,175 (AMI) and 9,837 (HF) patients. We calculated cumulative weekly incidences for first unplanned all-cause readmission and mortality during 6 months post-discharge and explored patient characteristics associated with these events.

Results

At 6 months, 20.4% and 9.9% (AMI) and 24.6% and 22.4% (HF) of patients had been readmitted or had died, respectively. The highest incidences were found in week 1. An increased risk for 14-day mortality after AMI was observed in patients who lived alone (hazard ratio (HR) 1.57, 95% confidence interval (CI) 1.01–2.44) and within 30 and 42 days in patients with a Charlson Comorbidity Index ≥3. In HF patients, increased risks for readmissions within 7, 30 and 42 days were found for a Charlson Comorbidity Index ≥3 and within 42 days for patients with an admission in the previous 6 months (HR 1.42, 95% CI 1.12–1.80). Non-native Dutch HF patients had an increased risk of 14-day mortality (HR 1.74, 95% CI 1.09–2.78).

Conclusion

The risk of unplanned readmission and mortality in older AMI and HF patients was highest in the 1st week post-discharge, and the effect of some risk factors changed over time. Transitional care interventions need to be provided as soon as possible to prevent early readmission and mortality.

The cardiac care bridge program: design of a randomized trial of nurse-coordinated transitional care in older hospitalized cardiac patients at high risk of readmission and mortality

BACKGROUND

After hospitalization for cardiac disease, older patients are at high risk of readmission and death. Although geriatric conditions increase this risk, treatment of older cardiac patients is limited to the management of cardiac diseases. The aim of this study is to investigate if unplanned hospital readmission and mortality can be reduced by the Cardiac Care Bridge transitional care program (CCB program) that integrates case management, disease management and home-based cardiac rehabilitation.

METHODS

In a randomized trial on patient level, 500 eligible patients ≥ 70 years and at high risk of readmission and mortality will be enrolled in six hospitals in the Netherlands. Included patients will receive a Comprehensive Geriatric Assessment (CGA) at admission. Randomization with stratified blocks will be used with pre-stratification by study site and cognitive status based on the Mini-Mental State Examination (15-23 vs ≥ 24). Patients enrolled in the intervention group will receive a CGA-based integrated care plan, a face-to-face handover with the community care registered nurse (CCRN) before discharge and four home visits post-discharge. The CCRNs collaborate with physical therapists, who will perform home-based cardiac rehabilitation and with a pharmacist who advices the CCRNs in medication management The control group will receive care as usual. The primary outcome is the incidence of first all-cause unplanned readmission or mortality within 6 months post-randomization. Secondary outcomes at three, six and 12 months after randomization are physical functioning, functional capacity, depression, anxiety, medication adherence, health-related quality of life, healthcare utilization and care giver burden.

DISCUSSION

This study will provide new knowledge on the effectiveness of the integration of geriatric and cardiac care.
