Changes in functional health status of older women with heart disease: evaluation of a program based on self-regulation

Social network interventions to support cardiac rehabilitation and secondary prevention in the management of people with heart disease

BACKGROUND

Globally, cardiovascular diseases (CVD, that is, coronary heart (CHD) and circulatory diseases combined) contribute to 31% of all deaths, more than any other cause. In line with guidance in the UK and globally, cardiac rehabilitation programmes are widely offered to people with heart disease, and include psychosocial, educational, health behaviour change, and risk management components. Social support and social network interventions have potential to improve outcomes of these programmes, but whether and how these interventions work is poorly understood.  OBJECTIVES: To assess the effectiveness of social network and social support interventions to support cardiac rehabilitation and secondary prevention in the management of people with heart disease. The comparator was usual care with no element of social support (i.e. secondary prevention alone or with cardiac rehabilitation).  SEARCH METHODS: We undertook a systematic search of the following databases on 9 August 2022: CENTRAL, MEDLINE, Embase, and the Web of Science. We also searched ClinicalTrials.gov and the WHO ICTRP. We reviewed the reference lists of relevant systematic reviews and included primary studies, and we contacted experts to identify additional studies.  SELECTION CRITERIA: We included randomised controlled trials (RCTs) of social network or social support interventions for people with heart disease. We included studies regardless of their duration of follow-up, and included those reported as full text, published as abstract only, and unpublished data.

DATA COLLECTION AND ANALYSIS

Using Covidence, two review authors independently screened all identified titles. We retrieved full-text study reports and publications marked 'included', and two review authors independently screened these, and conducted data extraction. Two authors independently assessed risk of bias, and assessed the certainty of the evidence using GRADE. Primary outcomes were all-cause mortality, cardiovascular-related mortality, all-cause hospital admission, cardiovascular-related hospital admission, and health-related quality of life (HRQoL) measured at > 12 months follow-up.  MAIN RESULTS: We included 54 RCTs (126 publications) reporting data for a total of 11,445 people with heart disease. The median follow-up was seven months and median sample size was 96 participants. Of included study participants, 6414 (56%) were male, and the mean age ranged from 48.6 to 76.3 years. Studies included heart failure (41%), mixed cardiac disease (31%), post-myocardial infarction (13%), post-revascularisation (7%), CHD (7%), and cardiac X syndrome (1%) patients. The median intervention duration was 12 weeks. We identified notable diversity in social network and social support interventions, across what was delivered, how, and by whom.  We assessed risk of bias (RoB) in primary outcomes at > 12 months follow-up as either 'low' (2/15 studies), 'some concerns' (11/15), or 'high' (2/15). 'Some concerns' or 'high' RoB resulted from insufficient detail on blinding of outcome assessors, data missingness, and absence of pre-agreed statistical analysis plans. In particular, HRQoL outcomes were at high RoB. Using the GRADE method, we assessed the certainty of evidence as low or very low across outcomes. Social network or social support interventions had no clear effect on all-cause mortality (risk ratio (RR) 0.75, 95% confidence interval (CI) 0.49 to 1.13, I2 = 40%) or cardiovascular-related mortality (RR 0.85, 95% CI 0.66 to 1.10, I2 = 0%) at > 12 months follow-up. The evidence suggests that social network or social support interventions for heart disease may result in little to no difference in all-cause hospital admission (RR 1.03, 95% CI 0.86 to 1.22, I2 = 0%), or cardiovascular-related hospital admission (RR 0.92, 95% CI 0.77 to 1.10, I2 = 16%), with a low level of certainty. The evidence was very uncertain regarding the impact of social network interventions on HRQoL at > 12 months follow-up (SF-36 physical component score: mean difference (MD) 31.53, 95% CI -28.65 to 91.71, I2 = 100%, 2 trials/comparisons, 166 participants; mental component score MD 30.62, 95% CI -33.88 to 95.13, I2 = 100%, 2 trials/comparisons, 166 participants).  Regarding secondary outcomes, there may be a decrease in both systolic and diastolic blood pressure with social network or social support interventions. There was no evidence of impact found on psychological well-being, smoking, cholesterol, myocardial infarction, revascularisation, return to work/education, social isolation or connectedness, patient satisfaction, or adverse events.  Results of meta-regression did not suggest that the intervention effect was related to risk of bias, intervention type, duration, setting, and delivery mode, population type, study location, participant age, or percentage of male participants.  AUTHORS' CONCLUSIONS: We found no strong evidence for the effectiveness of such interventions, although modest effects were identified in relation to blood pressure. While the data presented in this review are indicative of potential for positive effects, the review also highlights the lack of sufficient evidence to conclusively support such interventions for people with heart disease. Further high-quality, well-reported RCTs are required to fully explore the potential of social support interventions in this context. Future reporting of social network and social support interventions for people with heart disease needs to be significantly clearer, and more effectively theorised, in order to ascertain causal pathways and effect on outcomes.

What is the volume, diversity and nature of recent, robust evidence for the use of peer support in health and social care? An evidence and gap map

Background

Peer support interventions involve people drawing on shared personal experience to help one another improve their physical or mental health, or reduce social isolation. If effective, they may also lessen the demand on health and social care services, reducing costs. However, the design and delivery of peer support varies greatly, from the targeted problem or need, the setting and mode of delivery, to the number and content of sessions. Robust evidence is essential for policymakers commissioning peer support and practitioners delivering services in health care and community settings. This map draws together evidence on different types of peer support to support the design and delivery of interventions.

Objectives

The aim of this map was to provide an overview of the volume, diversity and nature of recent, high quality evidence on the effectiveness and cost-effectiveness of the use of peer support in health and social care.

Search Methods

We searched MEDLINE, seven further bibliographic databases, and Epistemonikos for systematic reviews (in October 2020), randomised controlled trials (in March 2021) and economic evaluations (in May 2021) on the effectiveness of peer support interventions in health and social care. We also conducted searches of Google Scholar, two trial registers, PROSPERO, and completed citation chasing on included studies.

Selection Criteria

Systematic reviews, randomised controlled trials and economic evaluations were included in the map. Included studies focused on adult populations with a defined health or social care need, were conducted in high-income countries, and published since 2015. Any measure of effectiveness was included, as was any form of peer support providing the peer had shared experience with the participant and a formalised role.

Data Collection and Analysis

Data were extracted on the type of peer support intervention and outcomes assessed in included studies. Standardised tools were used to assess study quality for all studies: assessing the methodological quality of systematic reviews 2 for systematic reviews; Cochrane risk of bias tool for randomised controlled trials; and consensus health economic criteria list for economic evaluations.

Main Results

We included 91 studies: 32 systematic reviews; 52 randomised controlled trials; and 7 economic evaluations. Whilst most included systematic reviews and economic evaluations were assessed to be of low or medium quality, the majority of randomised controlled trials were of higher quality. There were concentrations of evidence relating to different types of peer support, including education, psychological support, self-care/self-management and social support. Populations with long-term health conditions were most commonly studied. The majority of studies measured health-related indicators as outcomes; few studies assessed cost-effectiveness. Studies were unevenly distributed geographically, with most being conducted in the USA. Several gaps were evident regarding the delivery of peer support, particularly the integration of peers and professionals in delivering support and interventions of longer duration.

Authors' Conclusions

Although there is evidence available to inform the commissioning and delivery of peer support in health and social care, there are also clear gaps that need to be addressed to further support provision, particularly regarding cost-effectiveness. The effectiveness of peer support in different countries, with varying health and social care systems, is a priority for future research, as is the integration of peers with professionals in delivering peer support.

Clinical Effectiveness of a Self-Regulation Theory-Based Self-Management Intervention for Adults With Knee Osteoarthritis: A Long-Term Follow-Up

PURPOSE

To determine if there are long-term effects of a self-management intervention guided by self-regulation theory for adults with knee osteoarthritis at 6 and 12 months after completing the intervention.

DESIGN

This long-term follow-up study used a longitudinal quasi-experimental design with repeated measures.

METHODS

A convenience sample of 127 patients with knee osteoarthritis who were 45 to 64 years of age were recruited from outpatient clinics in Taiwan. The Self-Management Needs of Knee Osteoarthritis Scale was used to assess self-management needs at enrollment (baseline). To evaluate the long-term effects, participants were reassessed at 6 and 12 months after the intervention using the following questionnaires: The Knee Injury and Osteoarthritis Outcome Score, Healthcare Outcomes, and the Short-Form Health Survey. Generalized estimating equations compared assessments at baseline with scores at 6 and 12 months following completion of the intervention. Multiple regression was used to examine significant factors associated with the assessments.

FINDINGS

Participants had moderate levels of self-management needs. When assessments at 6 months were compared with baseline, scores for knee symptoms and physical function and quality of life showed significant improvements; significant reductions were seen in body mass index, unplanned medical consultations, and pain medication doses. Assessments at 12 months compared with baseline measures indicated these improvements were maintained. These improvements were significant from baseline measures at both 6 months and 12 months after adjustments were made for time and other significant variables.

CONCLUSIONS

Twelve months after completion of the intervention, the significant improvements seen at 6 months were maintained. Our findings demonstrate that the self-management intervention had significant long-term effects on knee symptoms and physical function, body mass index and pain medication doses, and overall quality of life for patients with moderate self-management needs of knee osteoarthritis.

CLINICAL RELEVANCE

Clinical care of knee osteoarthritis that includes a self-regulation theory-based self-management intervention could provide long-term benefits to patients.

The effects of a self-regulation programme on self-care behaviour in patients with heart failure: A randomized controlled trial

BACKGROUND

Self-care behaviour is important for patients with heart failure to prevent disease progression. More than half of patients have poor self-care behaviour. Self-regulation theory emphasizes that patients need to initiate monitoring of their symptoms, identify their own problems, and perform appropriate self-care behaviour. However, studies focused on interventions based on self-regulation theory for patients with heart failure are limited.

OBJECTIVES

To investigate the effects of a self-regulation programme on self-care behaviour in patients with heart failure.

DESIGN

A randomized controlled trial.

PARTICIPANTS AND SETTING

Eighty-two patients with heart failure were recruited from a cardiovascular outpatient department at a teaching hospital in northern Taiwan.

METHODS

Participants were randomly assigned to the intervention (n = 41) or control group (n = 41). The intervention group participated in a 4-week self-regulation programme, including one 20-to-30-min, face-to-face individual self-regulation education session and 15- to 20-min telephone follow-up counselling sessions twice per week for four weeks. The control group received only routine outpatient care. Self-care behaviour was measured by the Self-Care of Heart Failure Index at baseline, 4 weeks and 8 weeks after patients were enroled.

RESULTS

The intervention group reported improvements in self-care behaviours, including self-maintenance and self-confidence subscale scores, after four weeks of the self-regulation programme. In contrast, the control group showed no significant differences. Compared with the control group, the intervention group exhibited significantly greater improvements in self-care maintenance (B = 3.74, p = 0.01), self-care management (B = 6.33, p = 0.004), and self-care confidence (B = 5.15, p = 0.003) at four weeks but showed significantly greater improvements only in self-care management (B = 6.97, p = 0.03) and self-care confidence (B = 6.24, p = 0.001) at 8 weeks.

CONCLUSIONS

This study confirmed that a self-regulation programme could effectively improve self-care behaviour in patients with heart failure. Further studies with multicentre randomized controlled trials and larger populations of heart failure patients are necessary to evaluate the effect of this self-regulation programme in various regions and countries. Tweetable abstract: A home-based self-regulation programme could effectively improve self-care behaviour in patients with heart failure.

Comparative Effectiveness of the Core Components of Cardiac Rehabilitation on Mortality and Morbidity: A Systematic Review and Network Meta-Analysis

A systematic review and network meta-analysis (NMA) of randomized controlled trials (RCTs) evaluating the core components of cardiac rehabilitation (CR), nutritional counseling (NC), risk factor modification (RFM), psychosocial management (PM), patient education (PE), and exercise training (ET)) was undertaken. Published RCTs were identified from database inception dates to April 2017, and risk of bias assessed using Cochrane's tool. Endpoints included mortality (all-cause and cardiovascular (CV)) and morbidity (fatal and non-fatal myocardial infarction (MI), coronary artery bypass surgery (CABG), percutaneous coronary intervention (PCI), and hospitalization (all-cause and CV)). Meta-regression models decomposed treatment effects into the main effects of core components, and two-way or all-way interactions between them. Ultimately, 148 RCTs (50,965 participants) were included. Main effects models were best fitting for mortality (e.g., for all-cause, specifically PM (hazard ratio HR = 0.68, 95% credible interval CrI = 0.54⁻0.85) and ET (HR = 0.75, 95% CrI = 0.60⁻0.92) components effective), MI (e.g., for all-cause, specifically PM (hazard ratio HR = 0.76, 95% credible interval CrI = 0.57⁻0.99), ET (HR = 0.75, 95% CrI = 0.56⁻0.99) and PE (HR = 0.68, 95% CrI = 0.47⁻0.99) components effective) and hospitalization (e.g., all-cause, PM (HR = 0.76, 95% CrI = 0.58⁻0.96) effective). For revascularization (including CABG and PCI individually), the full interaction model was best-fitting. Given that each component, individual or in combination, was associated with mortality and/or morbidity, recommendations for comprehensive CR are warranted.

Optimal Gender-Specific Strategies for the Secondary Prevention of Heart Disease in Women: A SYSTEMATIC REVIEW

BACKGROUND

There is a paucity of evidence on gender-specific, individually tailored secondary prevention (cardiac rehabilitation [CR]) services for women with heart disease. Women participate less in CR programs, thus increasing their risk of further cardiac events. This review aims to (1) determine the effectiveness of gender-specific interventions specifically designed for women with heart disease, delivered in outpatient CR settings; and (2) classify key elements of effective CR strategies/models for women with heart disease.

METHODS

Using the PRISMA guidelines, this is a systematic review of CR models tailored to women to improve cardiovascular risk. Four databases were searched for randomized controlled trials (RCTs) between January 1974 and July 2017 published in peer-reviewed English language journals.

RESULTS

Three RCTs comprising 725 women of gender-specific CR strategies were identified. Significant improvements were found in one-third (1 study) of the included multicomponent CR strategies for outcomes including general health, social functioning, vitality, mental health, depression, and quality of life.

CONCLUSION

Further large-scale RCTs are required to replicate positive findings and accurately assess the capacity for gender-specific multicomponent CR programs that incorporate participant-driven collaborative models to moderate psychological risk and improve functional capacity and quality of life for women with heart disease.

Patient education in the management of coronary heart disease

BACKGROUND

Coronary heart disease (CHD) is the single most common cause of death globally. However, with falling CHD mortality rates, an increasing number of people live with CHD and may need support to manage their symptoms and improve prognosis. Cardiac rehabilitation is a complex multifaceted intervention which aims to improve the health outcomes of people with CHD. Cardiac rehabilitation consists of three core modalities: education, exercise training and psychological support. This is an update of a Cochrane systematic review previously published in 2011, which aims to investigate the specific impact of the educational component of cardiac rehabilitation.

OBJECTIVES

1. To assess the effects of patient education delivered as part of cardiac rehabilitation, compared with usual care on mortality, morbidity, health-related quality of life (HRQoL) and healthcare costs in patients with CHD.2. To explore the potential study level predictors of the effects of patient education in patients with CHD (e.g. individual versus group intervention, timing with respect to index cardiac event).

SEARCH METHODS

We updated searches from the previous Cochrane review, by searching the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library, Issue 6, 2016), MEDLINE (Ovid), Embase (Ovid), PsycINFO (Ovid) and CINAHL (EBSCO) in June 2016. Three trials registries, previous systematic reviews and reference lists of included studies were also searched. No language restrictions were applied.

SELECTION CRITERIA

1. Randomised controlled trials (RCTs) where the primary interventional intent was education delivered as part of cardiac rehabilitation.2. Studies with a minimum of six-months follow-up and published in 1990 or later.3. Adults with a diagnosis of CHD.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened all identified references for inclusion based on the above inclusion criteria. One author extracted study characteristics from the included trials and assessed their risk of bias; a second review author checked data. Two independent reviewers extracted outcome data onto a standardised collection form. For dichotomous variables, risk ratios and 95% confidence intervals (CI) were derived for each outcome. Heterogeneity amongst included studies was explored qualitatively and quantitatively. Where appropriate and possible, results from included studies were combined for each outcome to give an overall estimate of treatment effect. Given the degree of clinical heterogeneity seen in participant selection, interventions and comparators across studies, we decided it was appropriate to pool studies using random-effects modelling. We planned to undertake subgroup analysis and stratified meta-analysis, sensitivity analysis and meta-regression to examine potential treatment effect modifiers. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to evaluate the quality of the evidence and the GRADE profiler (GRADEpro GDT) to create summary of findings tables.

MAIN RESULTS

This updated review included a total of 22 trials which randomised 76,864 people with CHD to an education intervention or a 'no education' comparator. Nine new trials (8215 people) were included for this update. We judged most included studies as low risk of bias across most domains. Educational 'dose' ranged from one 40 minute face-to-face session plus a 15 minute follow-up call, to a four-week residential stay with 11 months of follow-up sessions. Control groups received usual medical care, typically consisting of referral to an outpatient cardiologist, primary care physician, or both.We found evidence of no difference in effect of education-based interventions on total mortality (13 studies, 10,075 participants; 189/5187 (3.6%) versus 222/4888 (4.6%); random effects risk ratio (RR) 0.80, 95% CI 0.60 to 1.05; moderate quality evidence). Individual causes of mortality were reported rarely, and we were unable to report separate results for cardiovascular mortality or non-cardiovascular mortality. There was evidence of no difference in effect of education-based interventions on fatal and/or non fatal myocardial infarction (MI) (2 studies, 209 participants; 7/107 (6.5%) versus 12/102 (11.8%); random effects RR 0.63, 95% CI 0.26 to 1.48; very low quality of evidence). However, there was some evidence of a reduction with education in fatal and/or non-fatal cardiovascular events (2 studies, 310 studies; 21/152 (13.8%) versus 61/158 (38.6%); random effects RR 0.36, 95% CI 0.23 to 0.56; low quality evidence). There was evidence of no difference in effect of education on the rate of total revascularisations (3 studies, 456 participants; 5/228 (2.2%) versus 8/228 (3.5%); random effects RR 0.58, 95% CI 0.19 to 1.71; very low quality evidence) or hospitalisations (5 studies, 14,849 participants; 656/10048 (6.5%) versus 381/4801 (7.9%); random effects RR 0.93, 95% CI 0.71 to 1.21; very low quality evidence). There was evidence of no difference between groups for all cause withdrawal (17 studies, 10,972 participants; 525/5632 (9.3%) versus 493/5340 (9.2%); random effects RR 1.04, 95% CI 0.88 to 1.22; low quality evidence). Although some health-related quality of life (HRQoL) domain scores were higher with education, there was no consistent evidence of superiority across all domains.

AUTHORS' CONCLUSIONS

We found no reduction in total mortality, in people who received education delivered as part of cardiac rehabilitation, compared to people in control groups (moderate quality evidence). There were no improvements in fatal or non fatal MI, total revascularisations or hospitalisations, with education. There was some evidence of a reduction in fatal and/or non-fatal cardiovascular events with education, but this was based on only two studies. There was also some evidence to suggest that education-based interventions may improve HRQoL. Our findings are supportive of current national and international clinical guidelines that cardiac rehabilitation for people with CHD should be comprehensive and include educational interventions together with exercise and psychological therapy. Further definitive research into education interventions for people with CHD is needed.

Longitudinal Effects of Social Support on the Health and Functioning of Older Women with Heart Disease

This study examined the effects of: 1) four dimensions of social support, 2) the number of close social ties, and 3) marital status on the physical and psychological health and functioning of 471 women aged 60 years and over with heart disease. Linear mixed models were used to assess the impact of each baseline social relations predictor on health outcomes at four-, 12-, and 18-month follow-up intervals. A second set of models examined the association between change in support variables over time with concomitant change in health outcomes. Results indicated that baseline emotional/informational support, positive social interaction, affectionate support, tangible support, number of close friends and relatives, and marital status all significantly predicted ( p < .05) one or more health outcomes over time. Increases in positive social interaction and emotional support over time were significantly associated with concurrent improvement in all self-reported physical and psychological health outcomes. Interventions that enhance the availability of emotional/informational support and promote social interaction are needed for this population.

The Evolution of an Innovative Heart Disease Management Program for Older Women: Integrating Quantitative and Qualitative Methods in Practice

Few studies in the literature describe how to combine quantitative and qualitative methods to enhance the development of health education interventions. This article describes the evolution and refinement of an innovative disease management program “take PRIDE” for older adults with heart disease. Over 15 years, information obtained from data collection methods including telephone interviews, focus groups, face-to-face interviews, and program process data illuminated and guided subsequent refinement of the program and led to new iterations for different participants. Qualitative and quantitative data were incorporated into the two key areas of program development (theoretical framework, objectives, format, and content) and evaluation (evaluation design, sampling, and measurement). Combining both types of data enhanced the opportunity to detect needed program changes, to increase understanding of the mechanisms by which the program effects were produced, and to enhance the relevance of the program to different groups of program participants.

Evaluation of Health Promotion Programs for Older Adults: An Introduction

This article provides an overview of the evaluation of evidence-based health promotion programs for older adults and introduces an upcoming series of related articles in the Journal of Applied Gerontology. With an aging population, a growing demand for health promotion and chronic disease self-management programs, and limited resources, evaluators must provide leadership to identify positive outcomes for adult older clients, inform program planning, and provide accountability to funders. The article addresses the following topics: the need for assessing the effectiveness of programs; research-based foundations for evaluation, specifically the RE-AIM model; the role of the evaluator; and guiding principles for evaluation and theoretical models that drive measurement. It concludes with the description of a process for conducting program evaluation based on the Center for Disease Control's framework for program evaluation, which actively engages program and community stakeholders in tailoring evaluation to the unique needs, characteristics, and barriers present in a community.

Perceptions and Experiences of Heart Disease: A Literature Review and Identification of a Research Agenda in Older Women

BACKGROUND

Following diagnosis of heart disease women have poorer health related outcomes compared with men. Nursing science lacks well-evaluated interventions to address the specific rehabilitative needs of older women with heart disease. This paper seeks to inform the development of nursing intervention studies by a review of published studies on the experiences and rehabilitative needs of older women with heart disease.

METHODS

The CINAHL, MEDLINE, FAMILY and PsychINFO databases were searched, identifying literature published from 1982 and written in English. Keywords used were women, old* (old, older) women, elderly women and: heart disease, heart failure, cardiac and rehabilitation. Hand searching of nursing and medical textbooks also occurred. These searches resulted in over 120 articles that met the criteria of describing experiences, perceptions, psychological responses and support rehabilitative needs of older women.

RESULTS

Older women present with symptoms that are different from those derived from a male-dominated research agenda and further there is a paucity of data related to evaluation of interventions tailored to the needs of women. Key themes emerging from the literature review include not only that older women compared with men have a poorer prognosis and experience greater disability moreover they: (1). are at a higher risk of psychosocial distress; (2). have a greater need for instrumental support and social support; (3). have an altered perception of risk; and (4). demonstrate the need for specific rehabilitation programs, tailored to their needs.

CONCLUSION

Future research should develop and evaluate intervention studies that better meet the unique needs of older women with heart disease. Particular emphasis needs to be on psychosocial aspects, given evidence that identify these are major concerns for women.

The effects of self-management intervention among middle-age adults with knee osteoarthritis

AIM

The aim of this study was to explore the effects of a self-management intervention for middle-aged adults with knee osteoarthritis.

BACKGROUND

Knee osteoarthritis is a common cause of lower limb disability in middle-aged and older adults. Use of self-management interventions that apply the self-regulation theory have not been reported for patients with knee osteoarthritis.

DESIGN

A quasi-experimental design was applied.

METHODS

Knee osteoarthritis patients were recruited from two medical centres in northern Taiwan by convenience sampling between July 2013-May 2014. We developed a self-management intervention programme for knee osteoarthritis; participants began an individualized programme 4 weeks after recruitment. Effectiveness of the intervention was evaluated using the Knee Injury and Osteoarthritis Outcome Score, Health Care Questionnaire and the Short-Form Health Survey. A generalized estimating equation compared assessment scores for 105 participants after the intervention (10 and 18 weeks) with scores at 4 weeks.

RESULTS

Knee symptoms and physical function scores significantly improved and quality-of-life scores significantly increased while body mass index, unplanned medical consultations and doses of pain medication significantly decreased at 10 and 18 weeks compared with 4 weeks. After adjusting for the effect of time- and significant-related factors, knee symptoms and physical function, body mass index and quality of life significantly improved at 10 and 18 weeks compared with 4 weeks.

CONCLUSIONS

The self-management intervention based on self-regulation theory, improved participants' symptoms and functions of knee osteoarthritis, overall health and quality of life. Offering self-management interventions in clinical practice can be beneficial for patients with knee osteoarthritis.

Intermediate outcomes of chronic disease self-management program offered by members of the Healthy Aging Regional Collaborative in South Florida

Currently, 80% of adults over the age of 65 have at least one chronic disease. The Chronic Disease Self-management Program (CDSMP) focuses on increasing self-efficacy for managing chronic disease. Few studies have evaluated the effectiveness of CDSMP when offered by multiple agencies, as a collaborative effort, in community-based settings. Seven agencies delivered 108 CDSMP workshops at 81 sites from October 1, 2008, to December 31, 2010. A total of 811 participants were eligible for analysis. Participants completed surveys at baseline and week 6, the end of instruction. Controlling for agency effect and general health at baseline, the general linear model was used to assess the significance of outcomes at 6 weeks. Outcomes showing significant improvement included self-efficacy to manage disease (p = .001), self-efficacy to manage emotions (p = .026), time spent walking (p = .008), and perceived social/role activities limitations (p = .001). Findings showed that CDSMP is an effective program at improving self-efficacy, increasing physical activity, and decreasing limitations.

Heart disease management by women: does intervention format matter?

A randomized controlled trial of two formats of a program (Women Take PRIDE) to enhance management of heart disease by patients was conducted. Older women (N = 575) were randomly assigned to a group or self-directed format or to a control group. Data regarding symptoms, functional health status, and weight were collected at baseline and at 4, 12, and 18 months. The formats produced different outcomes. At 18 months, the self-directed format was better than the control in reducing the number (p ≤ .02), frequency (p ≤ .03), and bothersomeness (p ≤ .02) of cardiac symptoms. The self-directed format was also better than the group format in reducing symptom frequency of all types (p ≤ .04). The group format improved ambulation at 12 months (p ≤ .04) and weight loss at 18 months (p ≤ .03), and group participants were more likely to complete the program (p ≤ .05). The availability of different learning formats could enhance management of cardiovascular disease by patients.

Results of a community translation of the "Women Take PRIDE" heart disease self-management program

This article reports the results of a community demonstration of an evidence-based heart disease self-management program for older women. Women Take PRIDE (WTP) is a group-based education and behavior modification program, based on social cognitive theory, designed to enhance heart disease self-management among older women. We implemented the program in community settings with 129 participants. Evaluation data was collected at baseline and at 4- and 12-month follow-ups. Outcomes included general health status, functional health status, and knowledge. Results showed significant improvements in self-rated health, energy, social functioning, knowledge of community resources, and number, frequency, and bother of cardiac symptoms. These results demonstrate that an evidence-based heart disease self-management program can be effective at improving health and quality of life among older women with heart disease when implemented in community settings.

Effects of a self-management program on patients with early-stage chronic kidney disease: a pilot study

BACKGROUND

Without intervention, renal function deteriorates in patients with chronic kidney disease (CKD).

AIM

This pilot study aimed to develop a self-management education program based on self-regulation theory and to evaluate its effects on self-efficacy, self-management behavior, and CKD progression among patients with early-stage CKD.

METHODS

In this single-group, pretest-posttest, repeated-measures, longitudinal study, participants underwent baseline pretesting (T0) and posttesting at 3 (T1), 6 (T2), and 12 (T3) months after a 5-week group-session self-management program.

RESULTS

Self-efficacy increased significantly at T2 (χ(2)=8.97, p=.02) and T3 (χ(2)=10.71, p=.01) compared with T0, but self-management behavior did not. A marginally significant decrease in serum creatinine levels was observed from T0 to T3 (χ(2)=6.29, p=.07) but estimated glomerular filtration rates remained stable throughout the 12-month period.

CONCLUSIONS

The results of this empirical study suggest that the theory-based intervention is feasible and has potential efficacy in retarding CKD progression.

Meta-analysis of the effect of cardiac rehabilitation interventions on depression outcomes in adults 64 years of age and older

Heart disease is a major cause of hospitalization and is associated with greater impairment than arthritis, diabetes mellitus, or lung disease. Depression is prevalent and a serious co-morbidity in heart disease with negative consequences including higher levels of chronic physical illness, decreased psychological well-being, and increased health care costs. The objective of the study was to examine with meta-analysis the impact of community-based cardiac rehabilitation (CR) treatment on depression outcomes in older adults. Randomized controlled trials comparing patients (≥64 years old) receiving CR to cardiac controls were considered. Meta-analyses were based on 18 studies that met inclusion criteria, comprising 1,926 treatment participants and 1,901 controls. Effect sizes (ESs) ranged from -0.39 (in favor of control group) to 1.09 (in favor of treatment group). Mean weighted ES was 0.28, and 11 studies showed positive ESs. Meta-analysis suggests that most CR programs delivered in the home can significantly mitigate depression symptoms. Tailored interventions combined with psychosocial interventions are likely to be more effective in decreasing depression in older adults with heart disease than usual care.

Effect of patient education in the management of coronary heart disease: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

To assess the effects of patient education on mortality, morbidity, health-related quality of life (HRQoL), and healthcare costs in people with coronary heart disease (CHD).

DESIGN

Systematic review and meta-analysis.

METHODS

Data sources were Cochrane Library, Medline, Embase, PsycINFO, CINAHL, and ongoing trial registries until August 2010. We also checked study references. The study selection was based on design (randomized controlled trials with follow up of at least 6 months, published from 1990 onwards), population (adults with CHD), intervention (patient education stated to be the primary intervention), and comparators (usual care or no educational intervention).

RESULTS

Thirteen studies (68,556 people with CHD) were included. Educational interventions ranged from two visits to a 4-week residential stay with 11 months of reinforcement sessions. Compared to no educational intervention, there was weak evidence that education reduced all-cause mortality (pooled relative risk (RR) 0.79, 95% CI 0.55 to 1.13) and cardiac morbidity outcomes: myocardial infarction (pooled RR 0.63, 95% CI 0.26 to 1.48), revascularization (pooled RR 0.58, 95% CI 0.19 to 1.71), and hospitalization (pooled RR 0.83, 95% CI 0.65 to 1.07) at median 18-months follow up. There was evidence to suggest that education can improve HRQoL and decrease healthcare costs by reductions in downstream healthcare utilization.

CONCLUSIONS

Our review had insufficient power to exclude clinically important effects of education on mortality and morbidity. Nevertheless it supports the practice of CHD secondary prevention and rehabilitation programmes including education as an intervention. Further research is needed to determine the most effective and cost-effective format, duration, timing, and methods of education delivery.

Patient education in the management of coronary heart disease

BACKGROUND

Cardiac rehabilitation (CR) is a complex multifaceted intervention consisting of three core modalities: education, exercise training and psychological support. Whilst exercise and psychological interventions for patients with coronary heart disease (CHD) have been the subject of Cochrane systematic reviews, the specific impact of the educational component of CR has not previously been investigated.

OBJECTIVES

1. Assess effects of patient education on mortality, morbidity, health-related quality of life (HRQofL) and healthcare costs in patients with CHD.2. Explore study level predictors of the effects of patient education (e.g. individual versus group intervention, timing with respect to index cardiac event).

SEARCH METHODS

The following databases were searched: The Cochrane Library, (CENTRAL, CDSR, DARE, HTA, NHSEED), MEDLINE (OVID), EMBASE (OVID), PsycINFO (EBSCOhost) and CINAHL (EBSCOhost). Previous systematic reviews and reference lists of included studies were also searched. No language restrictions were applied.

SELECTION CRITERIA

1. Randomised controlled trials (RCTs) where the primary interventional intent was education.2. Studies with a minimum of six-months follow-up and published in 1990 or later.3. Adults with diagnosis of CHD.

DATA COLLECTION AND ANALYSIS

Two review authors selected studies and extracted data. Attempts were made to contact all study authors to obtain relevant information not available in the published manuscript. For dichotomous variables, risk ratios and 95% confidence intervals (CI) were derived for each outcome. For continuous variables, mean differences and 95% CI were calculated for each outcome.

MAIN RESULTS

Thirteen RCTs involving 68,556 subjects with CHD and follow-up from six to 60 months were found. Overall, methodological quality of included studies was moderate to good. Educational 'dose' ranged from a total of two clinic visits to a four-week residential stay with 11 months of follow-up sessions. Control groups typically received usual medical care. There was no strong evidence of an effect of education on all-cause mortality (Relative Risk (RR): 0.79, 95% CI 0.55 to 1.13), cardiac morbidity (subsequent myocardial infarction RR: 0.63, 95% CI 0.26 to 1.48, revascularisation RR: 0.58, 95% CI 0.19 to 1.71) or hospitalisation (RR: 0.83, 95% CI:0.65 to 1.07). Whilst some HRQofL domain scores were higher with education, there was no consistent evidence of superiority across all domains. Different currencies and years studies were performed making direct comparison of healthcare costs challenging, although there is evidence to suggest education may be cost-saving by reducing subsequent healthcare utilisation.This review had insufficient power to exclude clinically important effects of education on mortality and morbidity of patients with CHD.

AUTHORS' CONCLUSIONS

We did not find strong evidence that education reduced all cause mortality, cardiac morbidity, revascularisation or hospitalisation compared to control. There was some evidence to suggest that education may improve HRQofL and reduce overall healthcare costs. Whilst our findings are generally supportive of current guidelines that CR should include not only exercise and psychological interventions, further research into education is needed.

Psychometric properties of the patient activation measure among multimorbid older adults

OBJECTIVES

The Patient Activation Measure (PAM) quantifies the extent to which people are informed about and involved in their health care. Objectives were to determine the psychometric properties of PAM among multimorbid older adults and evaluate a theoretical, four-stage model of patient activation. Methods. A cross-sectional analysis was used to assess the psychometric properties of PAM. Internal consistency was assessed using Cronbach α. Construct validity was evaluated using general linear modeling to compute associations between PAM scores and health-related behaviors, functional status, and health care quality. Latent class analysis was used to evaluate the theoretical four-stage structure of patient activation.

STUDY SETTING

Participants in a randomized trial of Guided Care (N = 855), a model of comprehensive health care for older adults with chronic conditions that put them at risk of using health services heavily during the coming year.

PRINCIPAL FINDINGS

Higher PAM activation scores and stage were positively associated with higher functional status, health care quality, and adherence to some health behaviors. Latent class analysis supported the multistage theory of patient activation.

CONCLUSIONS

The PAM is a reliable, valid, and potentially clinically useful measure of patient activation for multimorbid older adults.

Psychosocial interventions for the prevention of depression in older adults: systematic review and meta-analysis

OBJECTIVE

To assess the effectiveness of psychosocial interventions for the prevention of depression in older people.

METHOD

Systematic review and meta-analysis of prospective controlled trials.

RESULTS

Thirty studies were included. Overall, psychosocial interventions had a small but statistically significant effect on depressive symptoms (17 trials, standardized mean difference = -0.17, 95% CI = -0.31 to -0.03). In comparison with no-intervention controls, social activities were effective in reducing depressive symptoms, but results should be interpreted with caution due to the small number of trials. No statistically significant effect on depressive symptoms was found for physical exercise, skill training, reminiscence, or for multicomponent interventions.

DISCUSSION

Psychosocial interventions have a small but statistically significant effect in reducing depressive symptoms among older adults. The current evidence base for psychosocial interventions for primary prevention of depression in older people is weak, and further trials warranted especially for the most promising type of interventions evaluated, that is, social activities.

A meta-analysis of randomized control trials of home-based secondary prevention programs for coronary artery disease

BACKGROUND

A variety of different types of secondary prevention programs for coronary heart disease (CHD) exist. Home-based programs have become more common and may be more accessible or preferable to some patients. This review compared the benefits and costs of home-based programs with usual care and cardiac rehabilitation.

METHODS

A meta-analysis following a systematic search of 19 databases, existing reviews, and references was designed. Studies evaluated home-based interventions that addressed more than one main CHD risk factor using a randomized trial with a usual care or cardiac rehabilitation comparison group with data extractable for CHD patients only and reported in English as a full article or thesis.

RESULTS

Thirty-nine articles reporting 36 trials were reviewed. Compared with usual care, home-based interventions significantly improved quality of life [weighted mean difference: 0.23; 95% confidence interval (95% CI): 0.02-0.45], systolic blood pressure (weighted mean difference: -4.36 mmHg; 95% CI: -6.50 to -2.22), smoking cessation (difference in proportion: 14%; 95% CI: 0.02-0.26), total cholesterol (standardized mean difference: -0.33; 95% CI: -0.57 to -0.08), and depression (standardized mean difference: -0.33; 95% CI: -0.59 to -0.07). Effect sizes were small to moderate and trials were of low-to-moderate quality. Comparisons with cardiac rehabilitation could not be made because of the small number of trials and high levels of heterogeneity.

CONCLUSION

Home-based secondary prevention programs for CHD are an effective and relatively low-cost complement to hospital-based cardiac rehabilitation and should be considered for stable patients less likely to access or adhere to hospital-based services.

From the female perspective: Long-term effects on quality of life of a program for women with asthma

BACKGROUND

Although, among adults, asthma predominates in women, the role of sex and gender in asthma has only recently been studied. Moreover, only one study has focused on the management of asthma by women, reporting that 1 year subsequent to an intervention addressing sex and gender role factors, women's asthma status was improved.

OBJECTIVE

Data from a 2-year postintervention follow-up were assessed to determine whether there were longer-term effects on the asthma status and quality of life (QoL) of the participants.

METHODS

A randomized controlled design was used in which female patients with asthma, who were receiving services at the University of Michigan Health System, Ann Arbor, Michigan (2002-2006), were assigned to either a control group or a female-oriented intervention group that focused on management challenges related to sex and gender role factors. Data were collected at baseline and 2 years' postintervention (2008) by telephone interview and review of medical records. Measures included asthma-related QoL, health care and medication use for asthma, level of self-regulation, self-confidence in managing the condition, sex and gender role-related asthma problems, and days of missed work or school because of asthma. Data were analyzed using both generalized estimating equations logistic regression and log-linear regression.

RESULTS

The mean (SD) age of the 808 women participating in the study was 48.2 (13.1) years in the intervention group and 48.7 (14.3) years in the control group, and the percentage of minority participants was 15.8% and 16.3%, respectively. Despite randomization, women in the intervention group had more persistent asthma at baseline. At 2 years' postrandomization, the only significant difference in health care use was associated with scheduled office visits; no other significant health care use differences were evident. However, the women in the intervention group had a significantly greater decrease of asthma symptoms with sexual activity (P = 0.01) and greater reduction in days of work/school missed for asthma in winter months (P = 0.03), were better able to self-regulate (P = 0.01), were more confident in managing their asthma (P = 0.01), and had higher levels of asthma-related QoL (P = 0.02). They also had a greater reduction in the use of short-acting bronchodilators (ie, rescue medications) than did women in the control group (P < or = 0.05).

CONCLUSION

An intervention that focuses on female-specific aspects of asthma management may result in improved QoL and health status for women with asthma, as was evident 2 years' postintervention in this study.

Using Alternative Therapies to Manage Chronic Illness Among Older Adults: An Examination of the Health Context, Predisposing and Enabling Processes

This paper examines use of alternative therapies to manage a chronic illness among older adults with at least one of three major conditions: arthritis, heart disease, and hypertension. Drawing from developments in the health utilization literature, a focus is placed on the illness context, predisposing factors, and several factors deemed to enable persons to use complementary medicine. The baseline data (n = 879) from the 1995–96 North Shore Self-Care Study conducted in Vancouver, Canada were used for this study. Two dependent variables were analysed using logistic regression techniques – the first is based on a comprehensive question about using alternative therapies (such as herbal remedies, acupuncture, massage therapy, etc.) to manage a chronic condition; and the second uses a more specific question pertaining to meditation or praying. The results from the first analysis show that being younger, suffering from arthritis compared to hypertension, comorbidity, taking fewer medications, lower income, reading on the chronic condition, and the interaction between reading and illness self-efficacy are associated with trying alternative therapies. The findings for the second analysis show that being female, being younger, and not married, as well as reporting a more serious condition, illness duration and the interaction between having moderate levels of mutual aid and number of confidants result in a greater likelihood of trying meditation/prayer. Implications of these results are discussed in terms of their theoretical import, and their relevance for the degree to which unconventional and conventional medicine are complementary.

Service organisation for the secondary prevention of ischaemic heart disease in primary care

BACKGROUND

Ischaemic heart disease (IHD) is a major cause of mortality and morbidity and its prevalence is set to increase. Secondary prevention aims to prevent subsequent acute events in people with established IHD. While the benefits of individual medical and lifestyle interventions is established, the effectiveness of interventions which seek to improve the way secondary preventive care is delivered in primary care or community settings is less so.

OBJECTIVES

To assess the effectiveness of service organisation interventions, identifying which types and elements of service change are associated with most improvement in clinician and patient adherence to secondary prevention recommendations relating to risk factor levels and monitoring (blood pressure, cholesterol and lifestyle factors such as diet, exercise, smoking and obesity) and appropriate prophylactic medication.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2007, Issue 4), MEDLINE (1966 to Feb 2008), EMBASE (1980 to Feb 2008), and CINAHL (1981 to Feb 2008). Bibliographies were checked. No language restrictions were applied.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials of service organisation interventions in primary care or community settings in populations with established IHD.

DATA COLLECTION AND ANALYSIS

Analyses were conducted according to Cochrane recommendations and Odds Ratios (with 95% confidence intervals) reported for dichotomous outcomes, mean differences (with 95% CIs) for continuous outcomes.

MAIN RESULTS

Eleven studies involving 12,074 people with IHD were included. Increased proportions of patients with total cholesterol levels within recommended levels at 12 months, OR 1.90 (1.04 to 3.48), were associated with interventions that included regular planned appointments, patient education and structured monitoring of medication and risk factors, but significant heterogeneity was apparent. Results relating to blood pressure within target levels bordered on statistical significance. There were no significant effects of interventions on mean blood pressure or cholesterol levels, prescribing, smoking status or body mass index. Few data were available on the effect on diet. There was some suggestion of a "ceiling effect" whereby interventions have a diminishing beneficial effect once certain levels of risk factor management are reached.

AUTHORS' CONCLUSIONS

There is weak evidence that regular planned recall of patients for appointments, structured monitoring of risk factors and prescribing, and education for patients can be effective in increasing the proportions of patients within target levels for cholesterol control and blood pressure. Further research in this area would benefit from greater standardisation of the outcomes measured.

A systematic review of community-based health interventions on depression for older adults with heart disease

PURPOSE

This systematic review examined the effectiveness of community-based heart-health interventions on depression outcomes among homebound elderly (64 years and older) with heart disease.

DESIGN AND METHODS

A comprehensive literature search and meta analysis was performed to evaluate randomized controlled trials examining outpatient or home-based interventions. Methodological quality was assessed by standard criteria developed by the Cochrane Collaborative Initiative.

RESULTS

Fifteen studies met our inclusion criteria and all measured depression outcomes. Studies differed in scope and methodological rigor and sample sizes varied widely. Problems in treatment fidelity and masking of group assignment were noted. Great variability was found in depression outcomes due to the differences in methodology and intervention. Five studies reported significant treatment effect on depression; three of those employed home-based interventions and two were outpatient-clinic interventions. Ten studies were included in the meta analysis and the effect sizes (ESs) ranged from -0.39 (in favor of control group) to 0.65 (in favor of treatment group). The mean weighted ES was 0.11 and six studies showed positive ESs.

IMPLICATIONS

Mixed evidence for community-based heart disease interventions on depression outcomes was found. Future research should include sub-analysis of ESs of interventions on depression outcomes by different demographic characteristics of the study sample, common depression outcome measures, and different follow-up periods.

Pain catastrophizing in patients with noncardiac chest pain: relationships with pain, anxiety, and disability

OBJECTIVE

To examine the contributions of chest pain, anxiety, and pain catastrophizing to disability in 97 patients with noncardiac chest pain (NCCP) and to test whether chest pain and anxiety were related indirectly to greater disability via pain catastrophizing.

METHODS

Participants completed daily diaries measuring chest pain for 7 days before completing measures of pain catastrophizing, trait anxiety, and disability. Linear path model analyses examined the contributions of chest pain, trait anxiety, and catastrophizing to physical disability, psychosocial disability, and disability in work, home, and recreational activities.

RESULTS

Path models accounted for a significant amount of the variability in disability scales (R(2) = 0.35 to 0.52). Chest pain and anxiety accounted for 46% of the variance in pain catastrophizing. Both chest pain (beta = 0.18, Sobel test Z = 2.58, p < .01) and trait anxiety (beta = 0.14, Sobel test Z = 2.11, p < .05) demonstrated significant indirect relationships with physical disability via pain catastrophizing. Chest pain demonstrated a significant indirect relationship with psychosocial disability via pain catastrophizing (beta = 0.12, Sobel test Z = 1.96, p = .05). After controlling for the effects of chest pain and anxiety, pain catastrophizing was no longer related to disability in work, home, and recreational activities.

CONCLUSIONS

Chest pain and anxiety were directly related to greater disability and indirectly related to physical and psychosocial disability via pain catastrophizing. Efforts to improve functioning in patients with NCCP should consider addressing pain catastrophizing.

Harvest health: translation of the chronic disease self-management program for older African Americans in a senior setting

PURPOSE

We describe the translation of K. R. Lorig and colleagues' Chronic Disease Self-Management Program (CDSMP) for delivery in a senior center and evaluate pre-post benefits for African American participants.

DESIGN AND METHODS

Modifications to the CDSMP included a name change; an additional introductory session; and course augmentations involving culturally relevant foods, stress reduction techniques, and communicating with racially/ethnically diverse physicians. We recruited participants from senior center members, area churches, and word of mouth. We conducted baseline and 4-month post-interviews.

RESULTS

A total of 569 African American elders attended an introductory session, with 519 (91%) enrolling in the 6-session program. Of the 519, 444 (86%) completed >/=4 sessions and 414 (79%) completed pre-post interviews. We found small but statistically significant improvements for exercise (p =.001), use of cognitive management strategies (p =.001), energy/fatigue (p =.001), self-efficacy (p =.001), health distress (p =.001), and illness intrusiveness in different life domains (probabilities from.001-.021). We found no changes for health utilization. Outcomes did not differ by gender, number of sessions attended, number and type of chronic conditions, facilitator, leader, or recruitment site.

IMPLICATIONS

The CDSMP can be translated for delivery by trained senior center personnel to African American elders. Participant benefits compare favorably to original trial outcomes. The translated program is replicable and may help to address health disparities.

Heart disease management by women: does intervention format matter?

A randomized controlled trial of two formats of a program (Women Take PRIDE) to enhance management of heart disease by patients was conducted. Older women (N = 575) were randomly assigned to a group or self-directed format or to a control group. Data regarding symptoms, functional health status, and weight were collected at baseline and at 4, 12, and 18 months. The formats produced different outcomes. At 18 months, the self-directed format was better than the control in reducing the number (p < or = .02), frequency (p < or = .03), and bothersomeness (p < or = .02) of cardiac symptoms. The self-directed format was also better than the group format in reducing symptom frequency of all types (p < or = .04). The group format improved ambulation at 12 months (p < or = .04) and weight loss at 18 months (p < or = .03), and group participants were more likely to complete the program ( p < or = .05). The availability of different learning formats could enhance management of cardiovascular disease by patients.

A randomized trial of a self-regulation intervention for women with asthma

BACKGROUND

Women with asthma have greater mortality and morbidity than men in the United States. To date, there has been no rigorous evaluation of an intervention focused on the particular problems in asthma management faced by women. This study was a randomized clinical trial of a self-regulation, telephone counseling intervention emphasizing women's concerns, and sex and gender role factors in their management of asthma.

METHODS

A total of 808 women with diagnosed asthma were randomly assigned to the intervention group or a usual-care control group, including conventional asthma education. Interviews and medical record data were collected to assess psychosocial factors, and the behavioral factors of functioning, quality of life, symptoms, and health-care use at baseline and the subsequent 1 year. Generalized estimating equations, identity link, logit link, and log link were employed to analyze the data.

RESULTS

Compared to control subjects, the women receiving treatment had greater annual reductions in the average number of nights with asthma symptoms (p = 0.04), days of missed work/school (p = 0.03), emergency department visits (p = 0.04), unscheduled office visits (p = 0.01), and scheduled office visits (p = 0.04). They had greater recognition of asthma symptoms during the menstrual cycle (p = 0.0003), had decreased asthma symptoms with sexual activity (p = 0.008), and had greater improvement in quality of life (p = 0.0005), self-regulation (p = 0.03), and self-confidence to manage asthma (p = 0.001).

CONCLUSION

The intervention improved women's clinical status, functioning, quality of life, and health-care use. A program with a focus on asthma management problems particular to women can significantly assist female asthma patients.

Tai chi and perceived health status in older adults who are transitionally frail: a randomized controlled trial

BACKGROUND AND PURPOSE

Tai chi, a Chinese exercise derived from martial arts, while gaining popularity as an intervention for reducing falls in older adults, also may improve health status. The purpose of this study was to determine whether intense tai chi (TC) exercise could improve perceived health status and self-rated health (SRH) more than wellness education (WE) for older adults who are transitionally frail.

SUBJECTS

Study subjects were 269 women who were >or=70 years of age and who were recruited from 20 congregate independent senior living facilities.

METHODS

Participants took part in a 48-week, single-blind, randomized controlled trial. They were randomly assigned to receive either TC or WE interventions. Participants were interviewed before randomization and at 1 year regarding their perceived health status and SRH. Perceived health status was measured with the Sickness Impact Profile (SIP).

RESULTS

Compared with WE participants, TC participants reported significant improvements in the physical dimension and ambulation categories and borderline significant improvements in the body care and movement category of the SIP. Self-rated health did not change for either group.

DISCUSSION AND CONCLUSION

These findings suggest that older women who are transitionally frail and participate in intensive TC exercise demonstrate perceived health status benefits, most notably in ambulation.

Taking CHARGE: A self-management program for women following breast cancer treatment

The purpose of the study was to develop and evaluate Taking CHARGE, a self-management intervention designed to facilitate successful transitions to survivorship after breast cancer treatment. The Taking CHARGE intervention involves a two-pronged approach building on self-regulation principles to (1) equip women with self-management skills to address concerns following breast cancer treatment, and (2) provide information about common survivorship topics. The program involved four intervention contacts, two small group meetings and two individualized telephone sessions, delivered by nurse/health educators. This paper focuses on the process evaluation findings from a preliminary test of the Taking CHARGE intervention conducted with 25 women, aged 34-66 years, completing breast cancer treatment, who were randomly assigned to the intervention group. The process evaluation was conducted to obtain systematic information about the relevance and usefulness of the self-regulation approach, informational aspects, and program delivery. The findings indicated that intervention group participants found the Taking CHARGE program to be timely, relevant, and to have high utility in dealing with concerns that exist following breast cancer treatment. The process evaluation findings provide early evidence of the usefulness of the Taking CHARGE intervention for successful transition to survivorship following breast cancer treatment.

How good is assisted living? Findings and implications from an outcomes study

OBJECTIVES

The objective of this work was to determine 1-year medical outcomes, nursing home transfer, and functional change of assisted living (AL) residents and their relationship to care.

METHODS

On-site interviews and observations regarding the status and care of 2,078 residents in 193 facilities across four states were conducted; follow-up was by telephone interview with care providers.

RESULTS

Annual mortality and transfer rates were 14.4 and 21.3 per 100 residents. The probability of hospitalization and new/worsening morbidities over a standardized quarter per 100 residents was 12.7 and 22.7. Standardized change in function was notable among those who were transferred or died and small among others. Facility characteristics did not generally relate to medical outcomes and transfer, and those that related to functional change were small and occurred across multiple functions. Facilities that are affiliated with another level of care were more likely to transfer; nurse staffing was favorable for hospitalization but not transfer; and aide turnover was protective for mortality.

DISCUSSION

No single component defines "good" AL care. Predictors and outcomes are inconsistent, and effect sizes are small. Therefore, practice and policy should not focus narrowly on any one area or restrict the type of care-this being welcome news that supports diversity to accommodate individual preferences.

Understanding and Reducing Stress and Psychological Distress in Older Women with Heart Disease

Stress and psychological distress were assessed in 457 older women who were subsequently randomized to a six-week heart disease management program ("Women take PRIDE") or to a "usual care" control group. Baseline distress was significantly associated with age, symptoms, physical functioning, social support, optimism, and self-esteem (p < .05). Only 20% of women reported their physician had recommended reducing stress. At four months follow-up, intervention women compared to controls were significantly more likely to report reductions in stress levels (p = 0.02) and also showed improvement in emotional behavior (p = 0.09).

Can a disease self-management program reduce health care costs? The case of older women with heart disease

BACKGROUND

There is increasing interest in the potential for chronic disease self-management interventions to provide health benefits while reducing health care costs.

OBJECTIVES

To assess the impact of a heart disease management program on use of hospital services; to estimate associated hospital cost savings; and to compare potential cost savings with the cost of delivering the program.

RESEARCH DESIGN

Randomized, controlled study design. Data were collected from hospital billing records during a 36 month period. Multivariate models were used to compare health care use with cost between treatment and control groups. Estimated differences were then compared with the program costs to determine cost-effectiveness.

SUBJECTS

Participants were recruited from 6 hospital sites. Screening criteria included: female, 60 years or older, diagnosed cardiac disease, and seen by a physician approximately every 6 months. The study included 233 women in the intervention group and 219 in the control group. The "Women Take PRIDE" program utilizes a self-regulation process for addressing a problematic area of the heart regimen recommended by each woman's physician. It is tailored to the unique needs of older women.

MEASURES

Hospital admissions, in-patient days, emergency department visits.

RESULTS

Program participants experienced 46% fewer in-patient days (P <0.05) and 49% lower in-patient costs (P <0.10) than women in the control group. No significant differences in emergency department utilization were found. Hospital cost savings exceeded program costs by a ratio of nearly 5-to-1.

CONCLUSIONS

A heart disease self-management program can reduce health care utilization and potentially yield monetary benefits to a health plan.

The influence of social support on chronic illness self-management: a review and directions for research

A review of the empirical literature examining the relationship between social support and chronic illness self-management identified 29 articles, of which 22 were quantitative and 7 were qualitative. The majority of research in this area concerns diabetes self-management, with a few studies examining asthma, heart disease, and epilepsy management. Taken together, these studies provide evidence for a modest positive relationship between social support and chronic illness self-management, especially for diabetes. Dietary behavior appears to be particularly susceptible to social influences. In addition, social network members have potentially important negative influences on self-management There is a need to elucidate the underlying mechanisms by which support influences self-management and to examine whether this relationship varies by illness, type of support, and behavior. There is also a need to understand how the social environment may influence self-management in ways other than the provision of social support

The role of choice in health education intervention trials: a review and case study

Although the randomized, controlled trial (RCT) is considered the gold standard in research for determining the efficacy of health education interventions, such trials may be vulnerable to "preference effects"; that is, differential outcomes depending on whether an individual is randomized to his or her preferred treatment. In this study, we review theoretical and empirical literature regarding designs that account for such effects in medical research, and consider the appropriateness of these designs to health education research. To illustrate the application of a preference design to health education research, we present analyses using process data from a mixed RCT/preference trial comparing two formats (Group or Self-Directed) of the "Women take PRIDE" heart disease management program. Results indicate that being able to choose one's program format did not significantly affect the decision to participate in the study. However, women who chose the Group format were over 4 times as likely to attend at least one class and were twice as likely to attend a greater number of classes than those who were randomized to the Group format. Several predictors of format preference were also identified, with important implications for targeting disease-management education to this population.

[Intervention study using a fall prevention program to prevent functional decline of old-old elderly in a rural community]

The purpose of this study was to determine the effects of a fall prevention program for old-old elderly in a rural community in Japan. The subjects were 71 inhabitants aged 75 and over who used community health and welfare services such as day services and social activity classes. They were divided into two groups: 34 in the experimental group, and 37 controls. Physical therapists and care staff instructed the experimental group in fall prevention exercises once per two weeks from December 2000 to March 2001. The control group utilized the usual services without any special instructions. All subjects were evaluated by physical performance tests and a self-administered questionnaire before and after 4 months following the intervention. Collected data were analyzed by two-way ANOVA using intervention and time as independent variables, and physical performance tests as dependent variables. Twenty-three of the experimental group and 26 of the control group completed both baseline and follow-up surveys. There were no significant differences in physical ability between the two groups at the time of the baseline survey. The experimental group showed excellent compliance and participated in all sessions during the intervention period. Interaction effects on body mass index and Timed Up and Go Test were shown to be significant (F = 5.623, P < 0.01: F = 6.541, P < 0.05). There were no changes in terms of other physical and psychological factors. Our results showed specific exercises could improve some aspects of physical performance. Since the group exercise program can be effective for old-old elderly, it might contribute to decreasing falls and prolong independent living.

Strengthening asthma education to enhance disease control

This article focuses on reducing the barriers to effectively applying what is known about asthma patient education. One barrier to effective asthma control in individuals and populations is failure to recognize the range of influences on patients trying to manage their disease, including actions of family, clinicians, friends and neighbors, work or school mates, and significant people and organizations in the wider social environment. Another deterrent is failing to assist patients in developing their self-regulation skills. Other barriers are the lack of attention to the patients' asthma management goals (as opposed to clinical objectives) and overlooking signs that indicate follow-up education is needed. Five actions taken by health-care professionals could significantly enhance the effectiveness of asthma education: (1) make messages to patients and core skills taught consistent with national asthma guidelines; (2) focus on developing the patient's ability to self-regulate; (3) develop comprehensive plans for treatment and education that assign clinicians to appropriate educative roles; (4) use clinician communication techniques demonstrated to enhance asthma management by patients; and (5) ensure that all providers of education are themselves trained to achieve actions 1 to 4.

Cardiovascular health and physical activity in older adults: an integrative review of research methodology and results

PURPOSE OF THE PAPER: The purpose of this article is to review the literature on physical activity and its relationship to cardiovascular risk factors and mortality in older adults, in an effort to clarify the specific benefits and optimal level of physical activity for cardiovascular health in the older adult population.

BACKGROUND/RATIONALE

Despite physical activity being recognized as an important factor in the quality of life of older adults, there is a lack of clarity about the optimal level of physical activity that results in positive cardiovascular health benefits.

DESIGN/METHODS

An integrative review of the literature using the MEDLINE and CINAHL databases from 1990 through August 2000 was conducted identifying articles related to physical activity and cardiac risk factors, cardiovascular health, or mortality in the older adult.

RESULTS/FINDINGS

Forty-four research articles were reviewed. The intervention studies generally provided support for positive cardiovascular changes with exercise, but the results were inconsistent, sample sizes were small, and the outcomes, interventions, and measures of physical activity differed between studies. There was wide variation in the method of measurement of physical activity in the studies. Studies showed an increase in mortality in those who had a sedentary lifestyle compared to those who were more physically active. Results were mixed related to plasma lipids levels. Three studies showed a positive effect of physical activity on blood pressure (BP), while three studies showed no relationship. Each of the studies that evaluated the relationship between physical activity and pulse rate showed a decreased rate with increased physical activity.

CONCLUSIONS

The quantity and type of physical activity that should be recommended to bring about positive effects on cardiovascular health and mortality is unclear. There is support, however, that an active lifestyle decreases mortality. There is conflicting evidence to support positive effects of physical activity on cardiac risk factors. Further research is needed with larger sample sizes, better control of extraneous variables, and using measurements of physical activity that have undergone adequate psychometric testing.

The relative importance of physician communication, participatory decision making, and patient understanding in diabetes self-management

OBJECTIVE

Patients' self-management practices have substantial consequences on morbidity and mortality in diabetes. While the quality of patient-physician relations has been associated with improved health outcomes and functional status, little is known about the impact of different patient-physician interaction styles on patients' diabetes self-management. This study assessed the influence of patients' evaluation of their physicians' participatory decision-making style, rating of physician communication, and reported understanding of diabetes self-care on their self-reported diabetes management.

DESIGN

We surveyed 2,000 patients receiving diabetes care across 25 Veterans' Affairs facilities. We measured patients' evaluation of provider participatory decision making with a 4-item scale (Provider Participatory Decision-making Style [PDMstyle]; alpha = 0.96), rating of providers' communication with a 5-item scale (Provider Communication [PCOM]; alpha = 0.93), understanding of diabetes self-care with an 8-item scale (alpha = 0.90), and patients' completion of diabetes self-care activities (self-management) in 5 domains (alpha = 0.68). Using multivariable linear regression, we examined self-management with the independent associations of PDMstyle, PCOM, and Understanding.

RESULTS

Sixty-six percent of the sample completed the surveys (N = 1,314). Higher ratings in PDMstyle and PCOM were each associated with higher self-management assessments (P < .01 in all models). When modeled together, PCOM remained a significant independent predictor of self-management (standardized beta: 0.18; P < .001), but PDMstyle became nonsignificant. Adding Understanding to the model diminished the unique effect of PCOM in predicting self-management (standardized beta: 0.10; P =.004). Understanding was strongly and independently associated with self-management (standardized beta: 0.25; P < .001).

CONCLUSION

For these patients, ratings of providers' communication effectiveness were more important than a participatory decision-making style in predicting diabetes self-management. Reported understanding of self-care behaviors was highly predictive of and attenuated the effect of both PDMstyle and PCOM on self-management, raising the possibility that both provider styles enhance self-management through increased patient understanding or self-confidence.
