Psychosocial components of cardiac recovery and rehabilitation attendance

Factors that predict compliance in a virtual cardiac rehabilitation program

BACKGROUND

Despite the well-established benefits of cardiac rehabilitation (CR) for patients with cardiovascular disease (CVD), participation in CR remain low. Virtual CR programs present a unique opportunity to promote utilization. To date, few virtual CR cohorts have been analyzed for compliance. This study aims to determine factors that predict compliance within a large virtual CR program in the United States.

METHODS

We analyzed 1409 patients enrolled in the Kaiser Permanente Mid-Atlantic States Virtual CR program that consists of 12 CR sessions via telephone. Demographic characteristics, as well as body weight, blood pressure, HbA1c level, and smoking status were collected at admission. Patients were further classified by CVD diagnosis codes. Compliance was defined as at least 75% (9/12 sessions) attendance. Data was analyzed using simple and multiple regression models with significance defined as P < 0.05.

RESULTS

Age was the single strongest predictor for virtual CR compliance (adjusted R2 = 0.58; P < 0.001), and non-compliant patients were younger. HbA1C level, CVD diagnosis codes, and smoking status each moderately predicted compliance (adjusted R2 = 0.48, 0.42, and 0.31, respectively; P < 0.001). Smoking and HbA1C level combined in a multiple regression model significantly improved prediction of compliance (adjusted R2 = 0.79, P < 0.01). Sex, baseline weight or hypertension were not significant predictors of CR compliance.

CONCLUSIONS

Age, diabetes, CVD diagnoses, smoking status at admission are independent predictors of compliance in a large virtual CR program. Targeted intervention could be designed accordingly to improve CR compliance.

Effects of telecardiac rehabilitation on coronary heart disease: A PRISMA-compliant systematic review and meta-analysis

BACKGROUND

We performed a meta-analysis to investigate the effectiveness of telecardiac rehabilitation compared to center-based rehabilitation on cardiorespiratory fitness, blood pressure, blood lipids, body composition, and quality of life in patients with coronary heart disease.

METHODS

We searched the Medical Literature Analysis and Retrieval System Online, Cumulative Index to Nursing and Allied Health Literature, Cochrane, Embase, and Scopus databases and retrieved studies published until October 8, 2021. Randomized controlled trials were included to evaluate cardiorespiratory fitness, blood pressure, blood lipids, body composition, and quality of life after telecardiac rehabilitation and center-based rehabilitation in patients with coronary heart disease. The criteria of the Cochrane Handbook for Systematic Reviews of Interventions were used to evaluate the methodological quality of the studies. Funnel plot analysis and Egger test were performed to confirm the publication bias.

RESULTS

A total of 8 studies, including 750 participants, reported the effectiveness of the telecardiac rehabilitation and center-based rehabilitation included in the analysis. Except for total cholesterol and mental quality of life (P < .05), all parameters were not significantly different between telecardiac rehabilitation and center-based rehabilitation (P > .05).

CONCLUSION

Telecardiac rehabilitation was similar to the effects of center-based rehabilitation. The overall prognosis of patients with coronary heart disease can be improved by increasing patients' participation in cardiac rehabilitation through telerehabilitation.

Strategic Moments: IDENTIFYING OPPORTUNITIES TO ENGAGE CLIENTS IN ATTENDING CARDIAC REHABILITATION AND MAINTAINING LIFESTYLE CHANGES

PURPOSE

There has been extensive investigation of attendance rates at cardiac rehabilitation (CR) but little attention to client reasoning around attendance. This study explored decision-making drivers for attendance or nonattendance at CR programs in rural Victoria, Australia.

METHODS

All new patients referred to the CR programs at either the local hospital or community health service over a 6-month period were invited to participate and were interviewed before, after, and at 6 months post-CR. Content analysis was used to identify and group common themes that emerged from the semistructured interviews.

RESULTS

Eighty-four of the 114 patients referred agreed to participate in the study. Multiple barriers or facilitators affected the decisions of all clients. Three themes were identified that reflected the participant decision-making experience: (1) invitation and information about participation in CR; (2) person-centered approach to CR provision; and (3) ongoing support needs. Significant decision-making points identified were after the cardiac event; before and after hospital-based CR; before and after community-based CR; and at 6 months after the cardiac event. At any time there is a risk that the client can become lost or disengaged in the service system, but providing contact at these points can allow them to reengage.

CONCLUSIONS

This study provided the opportunity to hear participant voices, describing their decisions around CR attendance after a cardiac event. They highlighted the complexity of issues confronting them and suggested improvements to optimize their attendance and to maintain lifestyle changes.

Exercise Capacity and Self-Efficacy are Associated with Moderate-to-Vigorous Intensity Physical Activity in Children with Congenital Heart Disease

This study sought to determine whether exercise capacity, self-efficacy, and gross motor skills are associated with moderate-to-vigorous physical activity (MVPA) levels in children, and if these associations differ by congenital heart disease (CHD) type. Medical history was abstracted from chart review. We assessed MVPA levels (via accelerometry), percent-predicted peak oxygen consumption ([Formula: see text] cardiopulmonary exercise test), gross motor skill percentiles (test of gross motor development version-2), and self-efficacy [children's self-perceptions of adequacy and predilection for physical activity scale (CSAPPA scale)]. CHD patients (n = 137, range 4-12 years) included children with a repaired atrial septal defect (n = 31, mean ± standard deviation MVPA = 454 ± 246 min/week), transposition of the great arteries after the arterial switch operation (n = 34, MVPA = 423 ± 196 min/week), tetralogy of Fallot after primary repair (n = 37, MVPA = 389 ± 211 min/week), or single ventricle after the Fontan procedure (n = 35, MVPA = 405 ± 256 min/week). MVPA did not differ significantly between CHD groups (p = 0.68). Higher MVPA was associated with a higher percent-predicted [Formula: see text] (EST[95% CI] = 16.9[-0.2, 34] MVPA min/week per 10% increase in percent-predicted [Formula: see text] p = 0.05) and higher self-efficacy (EST[95% CI] = 5.2[1.0, 9.3] MVPA min/week per 1-unit increase in CSAPPA score, p = 0.02), after adjustment for age, sex, and testing seasonality, with no association with CHD type. Higher MVPA was not associated with gross motor skill percentile (p = 0.92). There were no significant interactions between CHD type and percent-predicted [Formula: see text] self-efficacy scores, and gross motor skill percentiles regarding their association with MVPA (p > 0.05 for all). Greater MVPA was associated with higher exercise capacity and self-efficacy, but not gross motor skills.

Direct to consumer advertising of robotic heart bypass surgery: effectiveness, patient satisfaction and clinical outcomes

Purpose

Robotic coronary artery bypass (rCABG) is a relatively novel and less invasive form of surgery. A yearlong direct-to-consumer advertising (DTCA) campaign was initiated to provide the community with information regarding rCABG, increase awareness and recruit patients. To optimize information content and ensure appropriate messaging for future campaigns, this study aims to analyze the campaign effectiveness and compared service quality perceptions and clinical outcomes, following surgery across DTCA-responder and control groups.

Design/methodology/approach

The institution initiated an rCABG program and one-year DTCA campaign. The authors prospectively documented all rCABG referrals prompted by these ads (DTCA-responder group) and concurrent referrals from medical providers (controls). Groups were compared according to baseline characteristics, perioperative outcomes, patient satisfaction (HCAHPS survey) and functional capacity at three weeks (Duke Activity Status Index). At six months, both groups were surveyed for patient satisfaction and unmet expectations.

Findings

There were 103 DTCA responders and 77 controls. The subset of responders that underwent rCABG (n = 54) had similar characteristics to controls, except they were younger, less likely to have lung disease or to be scheduled as an urgent case. Both groups had similar 30-day clinical outcomes, functional capacity recovery and overall satisfaction at three weeks. Follow-up interviews at six months and four years revealed that the DTCA group reported more unmet expectations regarding the “size of the skin incisions” and “recovery time” but no concern about “expertise of their surgeon”.

Practical implications

The DTCA campaign was effective at recruiting patients. The specific focus of the ads and narrow timeframe for decision-making about CABG lends confidence that the incremental cases seen during the campaign were prompted primarily by DTCA. However, differences in unmet expectations underscore the need to better understand the impact of message content on patients recruited via DTCA campaigns.

Originality/value

This is one of the first studies to provide real-world direct empirical evidence of patients’ clinical and attitudinal outcomes for DTCA campaigns. Furthermore, the findings contradict prevailing beliefs that DTCA is ineffective for prompting surgical referrals.

Cardiac rehabilitation programmes: predictors of non-attendance and drop-out

BACKGROUND

Despite evidence of its benefits, attendance at cardiac rehabilitation (CR) programmes is poor. Past studies to identify predictors of non-attendance have been limited by their small sample size, particularly for female patients. The present study was designed to identify socio-demographic and clinical predictors of non-attendance and drop-out separately for men and women automatically referred to CR programmes.

METHOD AND SUBJECTS

Prospective study of CR programme attendance amongst 808 patients consecutively admitted over an 11-month period to one of two hospitals in Melbourne, Australia, after acute myocardial infarction (AMI), or to undergo coronary artery bypass graft surgery (CABGS) or percutaneous coronary intervention (PCI).

RESULTS

Of the 652 eligible patients, 573 (88%) were successfully tracked at 4 months. Of these, 284 (49.6%) had attended a CR programme, while 272 (47.5%) had not. Using logistic regression, the significant predictors of programme non-attendance among men were having had a PCI, being a non-driver, and being aged 70 or more. The only factor predictive of non-attendance for women was being aged 70 or more. Amongst attenders, 67 (23.6%) patients discontinued the programme. Being a smoker, having diabetes and being unemployed at the time of hospital admission were predictive of programme drop-out by men. Being physically inactive at admission was predictive of programme drop-out by women.

CONCLUSIONS

The present study demonstrated a relatively high rate of CR programme attendance. Special attention needs to be directed towards males who are older, PCI patients, smokers, unemployed or non-drivers, and females who are older or inactive.

Improving Cardiac Rehabilitation: A View from the United Kingdom

Cardiac rehabilitation has assumed more prominence over the past decade, due largely to an increase in user demand, an improvement in the evidence base and an enhancement of its status. This paper presents a view from the United Kingdom and suggests some ways in which cardiac rehabilitation can be improved by focusing on a number of key issues: service organisation and delivery, process and outcome measurement, performance management, and education, training and continuing professional development. The paper concludes that there is a need to make cardiac rehabilitation more widely available using creative and flexible approaches to enhance access, participation and adherence.

Factors Associated with Non-Attendance at a Secondary Prevention Clinic for Cardiac Patients

Background: A randomised controlled trial was undertaken to test the effectiveness of a secondary prevention clinic. Secondary prevention programs can improve prognosis after an acute cardiac illness. It is therefore important to encourage high participation rates. Aim: The present study was a post-hoc analysis to identify factors associated with patients’ non-attendance at the clinic. Methods: We compared the baseline socio-demographic and clinical characteristics of 83 (73.5% male) non-attending patients and a random sample of 96 (85.4% male) attending patients. Self-reported data were gathered during interviews conducted on an average of 30 months after hospital admission to investigate long-term outcomes of the clinic. Results: Using logistic regression analysis, we found that non-attendance was significantly and independently associated with being female, being under 60 years of age, having no history of high cholesterol and having no angina prior to the event. In bivariate analyses, non-attendance was also associated with being born overseas and not having private health insurance. Conclusions: Likely non-attending patients should be identified early and more effective strategies should be devised to facilitate their participation in secondary prevention programs.

Evaluation of an intervention to increase self-efficacy for independent exercise in cardiac rehabilitation

Adherence to independent exercise is an essential outcome of cardiac rehabilitation (CR), yet limited theory-based interventions to improve adherence exist. This study tested the effects of an intervention based on Bandura's conceptualization of self-efficacy. The self-efficacy coaching intervention (SCI), a supplement to standard care, was designed to increase self-efficacy for independent exercise and independent exercise behavior in CR. We examined whether the SCI vs. attention control (AC) resulted in improved exercise self-efficacy (ESE), barriers self-efficacy (BARSE), and minutes of independent exercise for CR participants (n = 65). While between-group differences did not reach significance (p > .10) for any of the outcome measures, significant within-group changes were noted in BARSE scores and independent exercise (p < .001) for the SCI group. Change in independent exercise for the AC group was also significant (p =. 006). Further study is needed to explore whether short-term changes translate into maintenance of independent exercise participation after program completion.

Gender, race and cardiac rehabilitation in the United States: is there a difference in care?

Coronary heart disease is the leading cause of death within the United States, involving both genders and among all races and ethnic populations. Cardiac rehabilitation (CR) has been shown to significantly improve morbidity and mortality, and these benefits extend to individuals of both genders and all ages with coronary heart disease. Despite this, referral and participation rates remain surprisingly low. Furthermore, women and minorities have even lower referral rates than do their male and white counterparts. Over the course of this article, we will review CR referral and participation among women, as well as racial and ethnic minorities in the United States. We will also examine barriers to CR participation among these subgroups.

A systematic review of patient reported factors associated with uptake and completion of cardiovascular lifestyle behaviour change

BACKGROUND

Healthy lifestyles are an important facet of cardiovascular risk management. Unfortunately many individuals fail to engage with lifestyle change programmes. There are many factors that patients report as influencing their decisions about initiating lifestyle change. This is challenging for health care professionals who may lack the skills and time to address a broad range of barriers to lifestyle behaviour. Guidance on which factors to focus on during lifestyle consultations may assist healthcare professionals to hone their skills and knowledge leading to more productive patient interactions with ultimately better uptake of lifestyle behaviour change support. The aim of our study was to clarify which influences reported by patients predict uptake and completion of formal lifestyle change programmes.

METHODS

A systematic narrative review of quantitative observational studies reporting factors (influences) associated with uptake and completion of lifestyle behaviour change programmes. Quantitative observational studies involving patients at high risk of cardiovascular events were identified through electronic searching and screened against pre-defined selection criteria. Factors were extracted and organised into an existing qualitative framework.

RESULTS

374 factors were extracted from 32 studies. Factors most consistently associated with uptake of lifestyle change related to support from family and friends, transport and other costs, and beliefs about the causes of illness and lifestyle change. Depression and anxiety also appear to influence uptake as well as completion. Many factors show inconsistent patterns with respect to uptake and completion of lifestyle change programmes.

CONCLUSION

There are a small number of factors that consistently appear to influence uptake and completion of cardiovascular lifestyle behaviour change. These factors could be considered during patient consultations to promote a tailored approach to decision making about the most suitable type and level lifestyle behaviour change support.

Motivational factors of adherence to cardiac rehabilitation

BACKGROUND

Main suggested theories about patients' adherence to treatment regimens recognize the importance of motivation in positive changes in behaviors. Since cardiac diseases are chronic and common, cardiac rehabilitation as an effective prevention program is crucial in management of these diseases. There is always concern about the patients' adherence to cardiac rehabilitation. The aim of this study was to describe the motivational factors affecting the patients' participation and compliance to cardiac rehabilitation by recognizing and understanding the nature of patients' experiences.

MATERIALS AND METHODS

The participants were selected among the patients with cardiac diseases who were referred to cardiac rehabilitation in Isfahan Cardiovascular Research Center, Iran. The purposive sampling method was used and data saturation achieved after 8 semi-structured interviews.

FINDINGS

The three main concepts obtained from this study are "beliefs", "supporters" and "group cohesion".

CONCLUSIONS

In cardiac rehabilitation programs, emphasis on motivational factors affects the patient's adherence. It is suggested that in cardiac rehabilitation programs more attention should be paid to patients' beliefs, the role of patients' supporters and the role of group-based rehabilitation.

Perceptions of risk factors of cardiovascular disease and cardiac rehabilitation: a cross-sectional study targeting the Chinese population in the Midlands, UK

OBJECTIVES

To find out and explore the knowledge and opinion of Chinese people on cardiovascular disease and awareness of cardiac rehabilitation.

DESIGN

A cross-sectional study using 14-item bilingual (Chinese and English) questionnaires that include information on demographics, health status, cardiovascular disease related knowledge and perception, and awareness and understanding of the cardiac rehabilitation programme.

SETTING

Chinese community groups in the Midlands, UK from January to April 2008.

PARTICIPANTS

436 questionnaires from Chinese adults over 18 were obtained.

MAIN OUTCOME MEASURES

Current knowledge and attitude towards cardiovascular disease and awareness of cardiac rehabilitation.

RESULTS

Obesity was the most common risk factor identified by 80.7% of participants. Those originated from China had significantly less knowledge compared with subjects from other countries (p<0.001). People who have had exposure or experience of cardiac disease rated a higher risk of cardiac disease for Chinese living in the UK than people without experience. A majority (81.7%) used orthodox medicine and perceived it to be most effective against cardiac disease. Only 30% of participants were aware of cardiac rehabilitation.

CONCLUSION

The coronary artery disease (CAD) risk factors of Chinese population have increased significantly in the last decade. Cardiac rehabilitation awareness was poor among the sample population of this study and language barrier is still a problem. More large studies on Chinese population assessing CAD risk should be done to provide more evidence on CAD prevention for this growing population in the Western world.

Gender differences in recovery goals in patients after acute myocardial infarction

PURPOSE

: While cardiac rehabilitation has been established as an essential part of comprehensive cardiac care, participation rates for female patients are substantially lower than for male patients. Lower referral rates and higher ages of female patients partly explain this underutilization. Gender differences in recovery goals of cardiac patients have not been examined.

METHODS

: Five hundred ninety patients (22.2% women) admitted to the hospital because of an acute myocardial infarction answered a questionnaire regarding 24 goals in 5 domains of recovery (physical functioning, risk-factor modification, psychological well-being, independence in daily life, and return to work). In addition, psychological symptoms and medical data were assessed. Gender differences were tested by using χ and Student t tests, as well as multivariate logistic and linear regression models.

RESULTS

: Gender differences were found in 7 of the 24 recovery goals. After adjustment for psychosocial and clinical characteristics, women still reported a higher importance of "performance of household duties" (odds ratio [OR] = 8.62; 95% confidence interval [CI], 5.43-13.66), "independence in activities of daily living" (OR = 2.38; CI, 1.58-3.59), and "emotional equilibrium" (OR = 1.58, CI, 1.01-2.46). Men rated "physical endurance" and "reducing strain at workplace" as more important goals (OR = 0.64; CI, 0.42-0.97 and OR = 0.39; CI, 0.17-0.93). Except for psychological distress, gender differences in health status were not related to differences in goals.

CONCLUSIONS

: Gender roles and differences in social-life conditions may have an important influence on the recovery goals of patients after an acute myocardial infarction. Recovery goals should be explored when planning intervention programs for individual patients.

The Impact of High-Calorie-Expenditure Exercise on Quality of Life in Older Adults With Coronary Heart Disease

The acceptability of a high-calorie-expenditure (HCE) exercise program in older coronary heart disease patients participating in a behavioral weight-control program was evaluated. Seventy-four overweight patients (median age 63 yr) were randomly assigned to a 5-mo intervention of HCE exercise (3,000–3,500 kcal/wk daily walking) or standard cardiac-rehabilitation (CR) exercise (700–800 kcal/wk). Both groups received counseling to achieve a dietary caloric deficit of 3,500 kcal/ wk. Assessments at baseline and 5 mo included self-reported measures of quality of life and psychosocial variables. The HCE group experienced significantly greater weight loss (8.2 ± 4 vs. 3.7 ± 5 kg,p< .001). Changes from baseline to 5 mo on scores of physical, emotional, and social functioning were greater for the HCE than CR group (p< .05). HCE exercise also resulted in greater positive change in exercise enjoyment (p= .05), which was mediated by weight change. Even high-risk older adults can be successful in an HCE exercise program and experience no adverse physical or emotional changes.

Predicting cardiac rehabilitation attendance in a gender-tailored randomized clinical trial

PURPOSE

This study compared attendance of women participating in a motivationally enhanced, gender-tailored cardiac rehabilitation (CR) program with that of women attending a traditional outpatient CR program. We also sought to determine the significant baseline predictors of attendance of the exercise and education components of the interventions.

METHODS

Data from 252 women with CHD in the randomized clinical trial, the Women's-Only Cardiac Rehabilitation Program, were used in this study. The experimental design used 2 treatment groups: both receiving a comprehensive, 12-week, CR program, with 1 group receiving a gender-tailored, stage-of-change matched, behavioral enhancement using individualized motivational interviewing.

RESULTS

Compared with women in the traditional CR program, women in the gender-tailored program attended significantly more of the prescribed exercise (90% vs 77%) and education sessions (87% vs 56%). Group assignment accounted for about 5% of the variance in exercise attendance (F1,250 = 12.755, P < .001) and about 24% of the variance in education attendance (F1,250 = 77.942, P < .001). After controlling for group assignment, the baseline characteristics of smoking status, marital status, and anxiety accounted for about 17% of the variance in exercise attendance (F5,245 = 10.494, P < .001). Smoking status and marital status were significant baseline predictors of education attendance (F5,245 = 6.115, P < .001) after controlling for group assignment.

CONCLUSIONS

The long-standing, poor attendance of women in CR continues to be an unresolved international challenge. Gender-tailored, stage-matched, CR programs hold promise for enhancing attendance to prescribed protocols. Additional research examining the efficacy of gender-sensitive, motivationally enhanced CR for women compared with generic CR programs is warranted.

Examining the challenges of recruiting women into a cardiac rehabilitation clinical trial

PURPOSE

To examine the challenges of recruiting women for a 5-year cardiac rehabilitation randomized clinical trial; the aims of the study were to describe the range of recruitment sources, examine the myriad of factors contributing to ineligibility and nonparticipation of women during protocol screening, and discuss the challenges of enrolling women in the trial.

METHODS

The Women's-Only Phase II Cardiac Rehabilitation program used an experimental design with 2 treatment groups. Eligible participants included women who were (1) diagnosed with a myocardial infarction or stable angina or had undergone coronary revascularization within the last 12 months; (2) able to read, write, and speak English; and (3) older than 21 years. Responses to multiple recruitment strategies including automatic hospital referrals, physician office referrals, mass mailings, media advertisements, and community outreach are described. Reasons for ineligibility and nonparticipation in the trial are explored.

RESULTS

Automatic hospital order was the largest source of referral (n = 1,367, 81%) accounting for the highest enrollment rate of women (n = 184, 73%). The barriers to enrollment into the cardiac rehabilitation clinical trial included patient-oriented, provider-oriented, and programmatic factors. Of the referral sources, 52% were screened ineligible for provider-oriented reasons, 31% were ineligible due to patient-oriented factors, and 17.4% were linked to the study protocol. Study nonparticipation of those eligible (73.8%) was largely associated with patient-oriented factors (65.2%), with far less due to provider-related factors (4%) or study-related factors (3.4%).

CONCLUSION

Standing hospital orders facilitated enrollment to the cardiac rehabilitation clinical trial, yet women failed to participate predominantly due to significant patient-oriented biopsychosocial barriers.

Examining Oral Intake Temperature in Cardiac Surgery Patients

The effect of restricting the temperature of cardiac surgery patients' oral intake to room temperature or warmer, over the first 3 postoperative days, on gastrointestinal (GI) symptoms was examined. In all, 57 patients were randomly assigned to receive the intervention or usual care. GI symptoms were measured daily over the first 5 postoperative days. Following hospital discharge, GI symptoms and return to function data were collected over 4 postoperative weeks. On Postoperative Day 1, 41% of patients reported having GI symptoms, and they were significantly associated with higher cross-clamp time. Symptoms dissipated over time. There were no differences between the study groups in GI symptoms or return to function. Nearly 70% of patients who withdrew from the study were randomized to the intervention group. Difficulty associated with adhering to the study protocol was their primary reason for withdrawing. Given these findings, a large-scale clinical trial may not be warranted.

Self-efficacy for exercise in cardiac rehabilitation: review and recommendations

Despite the numerous physical and psychosocial benefits of exercise for coronary heart disease survivors, non-adherence to cardiac rehabilitation (CR) exercise is a major problem. Adherence to the lifestyle behavior change associated with CR involves both physical and self-regulatory skills. While self-regulatory efficacy is clearly linked to exercise adherence and adjustment, the literature on the relationship between self-efficacy and exercise among CR participants has not been systematically reviewed. A search of relevant databases identified 41 CR studies. Few studies measured self-regulatory efficacy for actions that facilitate adherence. Most studies examined self-efficacy during the intensive center-based phase of CR, with little attention to long-term maintenance. The CR literature could benefit by examining (a) self-efficacy as a major rehabilitation outcome, (b) measurement of self-regulatory efficacy for behavior change, (c) suspected moderators of self-efficacy (i.e. gender, age), and (d) self-efficacy relative to maintenance.

Perspectives of patients with type 2 diabetes following a critical cardiac event - an interpretative approach

AIM

This study aimed to gain in-depth understanding of the actual hospital and home experience of patients with diabetes and a critical cardiac event to assist in developing a pertinent diabetes self-management programme.

BACKGROUND

Type 2 diabetes can lead to cardiac complications requiring critical nursing care. Patients with diabetes and a history of cardiac disease are at greater risk of a further cardiac event. Greater self-efficacy or confidence in regulating diabetes and reducing the risk of a further cardiac event can be achieved through self-management programmes. However, the start of such a programme within the critical care environment presents challenges to critical care staff. It is important to understand patients' experiences and needs to improve quality of care.

DESIGN

An interpretive approach comprising open-ended interviews was used to collect data from patients with type 2 diabetes experiencing a cardiac event who had a coronary care unit admission in 2002-2003.

FINDINGS

The findings revealed that patients with diabetes who had a critical cardiac event experienced considerable feelings of hopelessness and fatigue. Patients also had concerns in the areas of self-confidence and confidence in health professionals. Patients indicated that greater self-confidence and confidence in health professionals would help their ability to manage their daily lives.

CONCLUSION

This paper provides in-depth understanding of the perspectives of patients with type 2 diabetes who have also been hospitalized for a critical cardiac event. This study concluded that further research is needed to fully explore whether enhancing self-confidence for these patients will lead to improved diabetes management, reduced negative feelings and more positive health outcomes.

RELEVANCE TO CLINICAL PRACTICE

The themes identified in this study provide direction and strategies for nursing staff to improve patients' confidence levels and reduce their feelings of hopelessness and fatigue.

Predictors of drop-out from an outpatient cardiac rehabilitation programme

OBJECTIVE

To investigate the prevalence and predictors of early drop-out from a cardiac rehabilitation programme and also whether completers and drop-out patients differed in relation to their illness cognitions, gender and psychological distress and quality of life.

DESIGN

A six-week outpatient cardiac rehabilitation programme.

SETTING

A university teaching hospital.

SUBJECTS

One hundred and eighty-nine patients were recruited from a consecutive series of outpatient referrals prior to a six-week comprehensive cardiac rehabilitation programme.

OUTCOME MEASURES

The revised Illness Perception Questionnaire, Quality of Life after Myocardial Infarction Questionnaire and the Hospital Anxiety and Depression Scale.

RESULTS

One hundred and forty-seven cardiac patients completed the cardiac rehabilitation programme. Forty-two (22%) patients dropped out in the first two weeks. Factors predicting early drop-out were female gender, younger age, higher Hospital Anxiety Depression Scale score, lower illness perception consequences and higher illness perception personal control and lower illness perception treatment control (all P < 0.05).

CONCLUSION

Over a fifth of the patients did not complete this typical cardiac rehabilitation programme. Female patients are more likely to drop out from cardiac rehabilitation than men. Psychological distress, younger age and lower perceptions of consequences, higher perception personal control and lower illness perception of treatment control were predictors of early drop-out from a cardiac rehabilitation programme.

Perceived control and change in physical functioning after coronary artery bypass grafting: A prospective study

We determined if perceived general and health-related control predicted change in physical functioning after coronary artery bypass grafting (CABG) in 1,038 patients. Control and physical functioning were assessed prior to hospital discharge and physical functioning also was assessed 6 weeks and 6 months later. The repeated measures outcome was modeled using a one-way analysis of covariance with interaction terms for General and Health-Related Control x Time. The sample was primarily composed of Caucasian (94%) men (73%) with a mean age of 65 +/- 11 years. Increasing health-related control was an independent predictor of positive change in physical functioning with a stronger effect in women. There was a nearly significant association between increasing general control and positive physical functioning change. Lack of significant interactions with time indicate that higher control has a beneficial impact on physical functioning change at 6 weeks and 6 months. Assessing control may help clinicians predict post-CABG physical functioning and may shape intervention efforts.

Pre-Coronary Artery Bypass Graft Measures and Enrollment in Cardiac Rehabilitation

PURPOSE

The aim of this study was to examine the relationship between exercise tolerance, functional status, exercise behavior, and enrollment in cardiac rehabilitation (CR), preoperatively in individuals undergoing coronary artery bypass graft (CABG) surgery.

METHODS

Seventy-eight individuals undergoing CABG were evaluated 1 to 7 days preoperatively using the following measures: 2-minute walk test (2MWT), Duke Activity Status Index (DASI), Cardiac Exercise Self-Efficacy Instrument (CESEI), Stages of Change Questionnaire (SCQ), Short-Form 12 (SF-12), Hospital Anxiety Depression scale, location of residence, and education level. Participants were contacted via telephone 10 to 12 weeks postoperatively to determine if they were referred and enrolled in CR. Participants completed mailed questionnaires for follow-up. In subsequent telephone interviews, individuals who were not enrolled in CR were asked to provide reasons for nonenrollment.

RESULTS

Overall enrollment in CR was 46%. No significant differences were found in 2MWT, CESEI, and DASI scores between enrolled and nonenrolled participants. Fifty-seven percent of urban-dwelling participants enrolled in CR compared to 29% of rural-dwelling participants (P < .01). Similarly, 65% of individuals with post-secondary education enrolled in CR compared to 38% of individuals without a post-secondary education (P = .05). The primary reasons for nonenrollment were behavioral intentions toward exercise and CR, accessibility, and healthcare team recommendation. Individuals who enrolled in CR demonstrated a larger postoperative improvement in CESEI score.

CONCLUSIONS

Location of residence and education level predicted CR enrollment, whereas preoperative exercise tolerance, functional status, and exercise attitudes did not predict enrollment.

Acute coronary syndromes: cardiac rehabilitation programmes and quality of life

AIMS

This paper reports a study examining the quality of life of clients following hospital admission with acute coronary syndrome in Hong Kong and their use of cardiac rehabilitation.

BACKGROUND

Coronary heart disease is a major source of mortality and morbidity in Hong Kong. Western studies have suggested that participation in cardiac rehabilitation improves the quality of life of clients with coronary heart disease yet the use of cardiac rehabilitation has been reported to be low. Better understanding is needed of the psychosocial status of these clients in Hong Kong and their use of cardiac rehabilitation services.

METHODS

A prospective, pretest-post-test study was carried out, with data collected over a period of 6 months with convenience sample of 182 participants. Baseline data were obtained within one week after hospital admission for individuals experiencing ACS. The second phase of data collection commenced at 6 months after hospital discharge. Total period of data collection took over 12 months between 2002 and 2003. The Chinese version of the SF-36 was used to assess quality of life, and demographic data and the extent to which clients participated in the cardiac rehabilitation programme were assessed.

RESULTS

Only 25% of the participants attended at least one session of the cardiac rehabilitation programme. Significant improvement occurred in all clients' perceived quality of life 6 months following initial hospital admission. No significant group differences in perceived quality of life were found according to whether or not clients used the cardiac rehabilitation services.

CONCLUSION

Improvement in perceived health-related quality of life was evident over a 6-month period. Yet our findings suggested that participation in the cardiac rehabilitation programme did not have any apparent effects in subjects' perceived quality of life. Further studies using both generic and disease-specific health-related quality of life instruments, as well as the inclusion of control group, are recommended. Continual improvement in cardiac rehabilitation programmes, and consideration of alternative modes of delivery other than the traditional attendance at hospital outpatient services, are also recommended.

Getting the most out of cardiac rehabilitation: a review of referral and adherence predictors

Comprehensive cardiac rehabilitation reduces mortality and morbidity but is utilised by only a fraction of eligible cardiac patients, with the participation rate of women being only about half that of men. This quantitative review assesses 32 studies meeting inclusion criteria, describing 16,804 patients, 5882 of whom were female. It was found that the main predictor of referral to a cardiac rehabilitation programme was the physician's endorsement of the effectiveness of such a programme. Patients were more likely to participate in rehabilitation programmes when they were actively referred, educated, married, possessed high self efficacy, and when the programmes were easily accessible. Patients were less likely to participate when they had to travel long distances to participate in a cardiac rehabilitation programme, or experienced guilt over family obligations. Women were less often referred and participated less often even after referral. In conclusion, many of the observed predictors, including those particular to women, are potentially modifiable with the help of health professionals.

Nursing Outcomes in Coronary Heart Disease

Nursing research has contributed to our knowledge of patients with coronary heart disease (CHD), although much of the research has focused on acute cardiac events. Active and ongoing programs of research into CHD patient outcomes are essential as significant gaps remain. Consistently effective strategies to help patients change risk behaviors, recognize salient symptoms, manage their CHD and ischemic symptoms, improve function and quality of life, and prevent subsequent coronary events are needed, especially in the elderly and those with multiple comorbidities.

Promoting participation in cardiac rehabilitation: patient choices and experiences

BACKGROUND

Cardiac rehabilitation can be an effective means for the secondary prevention of coronary heart disease, but a majority of eligible individuals fail to attend or drop out prematurely. Little research has examined patients' decisions about attendance.

AIMS

This paper reports a study examining patients' beliefs and decision-making about cardiac rehabilitation attendance.

METHODS

A purposive sample of patients from a mixed urban-rural region of Scotland was studied in 2001 using focus groups. Those who were eligible for a standardized 12-week cardiac rehabilitation programme were compared, with separate focus groups held for individuals with high attendance (>60% attendance; n = 27), high rates of attrition (<60% attendance; n = 9) and non-attendance (0% attendance; n = 8). A total of 44 patients (33 men; 11 women) took part in eight focus groups.

RESULTS

Participants from all groups held sophisticated and cohesive frameworks of beliefs that influenced their attendance decisions. These beliefs related to the self, coronary heart disease, cardiac rehabilitation, other attending patients, and health professionals' knowledge base. An enduring embarrassment about group or public exercise also influenced attendance. Those who attended reported increased faith in their bodies, a heightened sense of fitness and a willingness to support new patients who attended.

CONCLUSIONS

Reassurance to ease exercise embarrassment should be given before and during the early stages of programmes, and this could be provided by existing patients. Strategies to promote inclusion should address the inhibiting factors identified in the study, and should present cardiac rehabilitation as a comprehensive programme of activities likely to be of benefit to the individual irrespective of personal characteristics, such as age, sex or exercise capacity.

Psychosocial distress and impaired quality of life ??? targets neglected in the secondary prevention in women with ischaemic heart disease

BACKGROUND

Secondary prevention in patients with ischaemic heart disease (IHD) focusing on classical risk factors has been less successful in women than in men. Previous studies have suggested that psychosocial factors may be new targets for secondary prevention. In the present study, psychosocial factors have been compared in women with and without IHD.

METHODS AND SUBJECTS

Using a cross-sectional comparison, classical cardiovascular risk factors and self-rated stress behaviour, vital exhaustion, stressful life events and quality of life were assessed in 198 women (age 35-77 years) who had IHD and a population-based sample of 206 women (age 45-74 years) without IHD.

RESULTS

Control of classical risk factors was most often adequate in women with IHD. The prevalence of smoking was 9% in women with versus 18% in women without IHD (P<0.001), blood pressure levels were similar, and a very large share of women with IHD were on treatment with anti-thrombotic, anti-hypertensive and/or lipid-lowering drugs (P<0.001 compared with women free of IHD). In contrast, women with IHD scored significantly worse than women without IHD in self-rated stress behaviour (P=0.003 after adjustment for other possible determinants), and in vital exhaustion (P=0.003). In univariate analyses, quality of life was significantly worse in women with IHD. Stressful life events did not differ between the two groups.

CONCLUSIONS

In this group of women with IHD, control of classical risk factors was good, whereas control of psychosocial risk factors was clearly inadequate. Secondary prevention by psychosocial intervention in women with IHD should be evaluated in randomized controlled trials.

Why are women missing from outpatient cardiac rehabilitation programs? A review of multilevel factors affecting referral, enrollment, and completion

OBJECTIVES

The objectives of this paper are to (1) systematically review the evidence for patient, provider, and programmatic factors that may influence women's referral to, enrollment in, and completion of outpatient cardiac rehabilitation and (2) make empirically based recommendations for future women's health research.

METHODS

Using a defined inclusion/exclusion criteria, this review involved a systematic review and description analysis of the published peer-review literature.

RESULTS

The review yielded 23 studies described in 25 publications. Although gaps in the knowledge base exist and several methodological concerns limit the evidence, this body of work suggests that age, personal resources, low rates of physician referral, and weak recommendations to participate in rehabilitation may explain why women are missing from this life-saving intervention.

CONCLUSIONS

Practitioners engaged in the care of eligible cardiac patients should be aware of the evidence for the effectiveness of cardiac rehabilitation, and researchers should examine programmatic and provider factors that affect women's participation.

'I'm still waiting...': barriers to accessing cardiac rehabilitation services

BACKGROUND

The United Kingdom (UK) National Service Framework for coronary heart disease challenges health services to address existing problems regarding the quality and content of cardiac rehabilitation services. Concern also exists regarding inequalities in access to services. The South Yorkshire Coalfields Health Action Zone (SYCHAZ) funded this study to harness the views and experiences of staff and patients regarding existing services. The intention is to use the information gained to develop acceptable and accessible services for the future.

AIMS

To explore what barriers exist for patients in accessing cardiac rehabilitation services within the South Yorkshire Coalfield locality.

ETHICAL ISSUES AND APPROVAL

Patients were identified and recruited with the assistance of staff responsible for their care. Informed consent was obtained prior to participation. Approval was obtained from the relevant Ethics Committees.

METHODS

Qualitative methods were used, including semi-structured interviews and Framework Analysis techniques. Purposive sampling was used to select participants.

INSTRUMENTS

Semi-structured individual interviews of 15 staff and 20 postmyocardial infarction patients. One group interview with seven health visitors and two with lay members of heart support groups.

OUTCOMES

Barriers to accessing cardiac rehabilitation.

RESULTS

This study revealed a limited service capacity. Big gaps exist between patches of service activity that most patients appear to slip through. Problems in accessing the service were categorized into five themes: absence, waiting, communication, understanding, and appropriateness. Some groups fared worse in terms of access to services, for example women, the elderly and those in traditional working class coalfields communities. Professional and more affluent participants appeared better able to negotiate their way around the system by seeking out advice or 'going private'.

LIMITATIONS

The omission of medical staff and ethnic minority patients.

CONCLUSIONS

Cardiac rehabilitation in the policy targets in UK will only be met with substantial investment to address the barriers identified here.

Preparing for change in the secondary prevention of coronary heart disease: a qualitative evaluation of cardiac rehabilitation within a region of Scotland

BACKGROUND

Secondary prevention of Coronary Heart Disease (CHD) is often poorly managed and its benefits attained in only a minority of those with CHD. Guidelines developed in the United Kingdom and North America suggest that in future cardiac rehabilitation programmes should provide services through individualized programmes that cater for a wide range of conditions associated with CHD. This will involve substantial and costly changes to current programmes that are mostly standardized and for postmyocardial infarction patients. Based on change theory, this study examined the dynamics, strengths and weaknesses of an existing programme in a Scottish region which was due to undergo the changes suggested by guidelines.

AIM

To examine the perceived provision of secondary prevention services for CHD from the perspectives of health professionals within one region in the West of Scotland.

METHODS

A purposive sample of 14 health professionals (eight primary and six secondary care health professionals) was selected to cover a range of professional roles including both specialists and generalists. Separate focus group discussions (2) were held with primary care and secondary care professionals.

FINDINGS

Whilst the health professionals were enthusiastic about CHD prevention and their involvement, they perceived barriers to the success of the existing service as being complex and multifactorial, including patient, social and service-related factors. Although both groups identified motivation as the most influential personal factor, secondary care staff tended to focus on the importance of patient factors in influencing motivation to change, whereas the primary care staff referred more to the cumulative effects of social and cultural factors. Professionals highlighted weaknesses in the transition between hospital and community-based services with regard to the information flow between primary and secondary care.

CONCLUSIONS

Although the study has immediate relevance for the local area, it highlighted issues of more general relevance to cardiac rehabilitation programme development and intersectoral working, such as communications and role perceptions in multi-professional working and the need to adapt services to local socio-economic conditions.

Factors associated with cardiac rehabilitation attendance: a systematic review of the literature

BACKGROUND

Many eligible patients fail to attend cardiac rehabilitation courses.

OBJECTIVE

To undertake a systematic literature review of studies that have investigated factors associated with cardiac rehabilitation attendance.

METHODS

Literature published between 1978 and 2001 was searched using the MEDLINE, PSYCINFO and CINAHL computerized databases. Studies were sought that examined course attendance in eligible patient samples. Studies had to include at least one baseline predictor variable.

RESULTS

Fifteen studies were identified and predictor variables were usually categorized as sociodemographic, medical and psychological. Nonattenders are more likely to be older, to have lower income/greater deprivation, to deny the severity of their illness; they are less likely to believe they can influence its outcome or to perceive that their physician recommends cardiac rehabilitation. Job status, gender and health concerns play an indirect role in attendance behaviour. Comparison of results between studies could be influenced by different case-mix, measurement instruments and country of origin.

CONCLUSION

A number of factors predict cardiac rehabilitation attendance and some of these are potentially modifiable.

Impact of in-home defibrillators on postmyocardial infarction patients and their significant others: an interview study

OBJECTIVE

To investigate the impact of automated external defibrillator (AED) placement in the homes of postmyocardial infarction (MI) patients and their significant others.

DESIGN

This qualitative study used a semistructured interview to examine a nonrandomized convenience sample recruited from a larger study of home AEDs.

SETTING AND PARTICIPANTS

Patients (and their significant others) were recruited from an ongoing study of AED use in the home. Seventeen interviews with 15 patients (14 men, 1 woman) and 16 significant others (1 man, 15 women) aged 39 to 80 years were performed in patients' homes.

METHODS

Verbatim transcripts of audiotaped interviews were reviewed, and responses were categorized. Other data were obtained from hospital chart abstraction.

RESULTS

The majority of subjects noted only positive effects of the presence of home AEDs (eg, giving them feelings of security and control). There was no evidence that AED presence in the home caused excessive anxiety or stress either in patients or their significant others, nor were they perceived to cause relationship stress. On average, patients and their significant others estimated a 38% and 43% (respectively) risk of cardiac arrest and a 92% and 87% likelihood of a successful resuscitation with the use of the AED. Subjects' perceived risk of cardiac arrest were subjectively related to their estimate of current health status, size of infarction, and symptoms during their MI. Subjects also related their estimates of risk to their likelihood of traveling with their AED and whether they would consider purchasing one. Significant others had high confidence in their ability to properly use the AED.

CONCLUSIONS

AEDs were valued highly by subjects and enhanced their perceived control over their heart disease. This was especially true for subjects who believed that their risk of cardiac arrest was high. The possible effects of providing education regarding expert estimates of the likelihood of cardiac arrest and of a successful resuscitation at the time of AED placement are discussed.
