Alternative models of cardiac rehabilitation: a systematic review

The traditional hospital-based model of cardiac rehabilitation faces substantial challenges, such as cost and accessibility. These challenges have led to the development of alternative models of cardiac rehabilitation in recent years. The aim of this study was to identify and critique evidence for the effectiveness of these alternative models. A total of 22 databases were searched to identify quantitative studies or systematic reviews of quantitative studies regarding the effectiveness of alternative models of cardiac rehabilitation. Included studies were appraised using a Critical Appraisal Skills Programme tool and the National Health and Medical Research Council’s designations for Level of Evidence. The 83 included articles described interventions in the following broad categories of alternative models of care: multifactorial individualized telehealth, internet based, telehealth focused on exercise, telehealth focused on recovery, community- or home-based, and complementary therapies. Multifactorial individualized telehealth and community- or home-based cardiac rehabilitation are effective alternative models of cardiac rehabilitation, as they have produced similar reductions in cardiovascular disease risk factors compared with hospital-based programmes. While further research is required to address the paucity of data available regarding the effectiveness of alternative models of cardiac rehabilitation in rural, remote, and culturally and linguistically diverse populations, our review indicates there is no need to rely on hospital-based strategies alone to deliver effective cardiac rehabilitation. Local healthcare systems should strive to integrate alternative models of cardiac rehabilitation, such as brief telehealth interventions tailored to individual’s risk factor profiles as well as community- or home-based programmes, in order to ensure there are choices available for patients that best fit their needs, risk factor profile, and preferences.

Impact of a regionalised clinical cardiac support network on mortality among rural patients with myocardial infarction.

Objective: To evaluate the impact of the regionalised Integrated Cardiovascular Clinical Network (ICCNet) on 30‐day mortality among patients with myocardial infarction (MI) in an Australian rural setting.

A comparison of Australian rural and metropolitan cardiovascular risk and mortality: the Greater Green Triangle and North West Adelaide population surveys

Objectives Cardiovascular (CVD) mortality disparities between rural/regional and urban-dwelling residents of Australia are persistent. Unavailability of biomedical CVD risk factor data has, until now, limited efforts to understand the causes of the disparity. This study aimed to further investigate such disparities. Design Comparison of (1) CVD risk measures between a regional (Greater Green Triangle Risk Factor Study (GGT RFS, cross-sectional study, 2004–2006) and an urban population (North West Adelaide Health Study (NWAHS, longitudinal cohort study, 2004–2006); (2) Australian Bureau of Statistics (ABS) CVD mortality rates between these and other Australian regions; and (3) ABS CVD mortality rates by an area-level indicator of socioeconomic status, the Index of Relative Socioeconomic Disadvantage (IRSD). Setting Greater Green Triangle (GGT, Limestone Coast, Wimmera and Corangamite Shires) of South-Western Victoria and North-West Adelaide (NWA). Participants 1563 GGT RFS and 3036 NWAHS stage 2 participants (aged 25–74) provided some information (self-administered questionnaire +/− anthropometric and biomedical measurements). Primary and secondary outcome measures Age-group specific measures of absolute CVD risk, ABS CVD mortality rates by study group and Australian Standard Geographical Classification (ASGC) region. Results Few significant differences in CVD risk between the study regions, with absolute CVD risk ranging from approximately 5% to 30% in the 35–39 and 70–74 age groups, respectively. Similar mean 2003–2007 (crude) mortality rates in GGT (98, 95% CI 87 to 111), NWA (103, 95% CI 96 to 110) and regional Australia (92, 95% CI 91 to 94). NWA mortality rates exceeded that of other city areas (70, 95% CI 69 to 71). Lower measures of socioeconomic status were associated with worse CVD outcomes regardless of geographic location. Conclusions Metropolitan areas do not always have better CVD risk factor profiles and outcomes than rural/regional areas. Needs assessments are required for different settings to elucidate relative contributions of the multiple determinants of risk and appropriate cardiac healthcare strategies to improve outcomes.

Relationship between elevated preoperative troponin T and adverse outcomes following cardiac surgery

Background:  The prognostic value of troponin T (TnT) has been demonstrated in patients following a myocardial infarction. There are limited data regarding the prognostic utility of preoperative TnT in patients undergoing cardiac surgery. The aim of the present study was to determine if elevated preoperative TnT is a predictor of more complex recovery outcomes in the cardiac surgical setting.

Chronic disease risk factors in rural Australia: results from the greater green triangle risk factor surveys.

The aim of this article was to assess the level and prevalence of major chronic disease risk factors among rural adults. Two cross-sectional surveys were carried out in 2004 and 2005 in the southeast of South Australia and the southwest of Victoria. Altogether 891 randomly selected persons aged 25 to 74 years participated in the studies. Surveys included a self-administered questionnaire, physical measurements, and a venous blood specimen for lipid analyses. Two thirds of participants had cholesterol levels ≥5.0 mmol/L. The prevalence of high diastolic blood pressure (≥90 mm Hg) was 22% for men and 10% for women in southeast of South Australia, and less than 10% for both sexes in southwest of Victoria. Two thirds of participants were overweight or obese (body mass index ≥25 kg/m2). About 15% of men and slightly less women were daily smokers. The abnormal risk factor levels underline the need for targeted prevention activities in the Greater Green Triangle region. Continuing surveillance of levels and patterns of risk factors is fundamentally important for planning and evaluating preventive activities.

A Pilot Study of the Feasibility of an Internet-based Electronic Outpatient Cardiac Rehabilitation (eOCR) Program in Rural Primary Care

BACKGROUND Interventions that facilitate access to cardiac rehabilitation and secondary prevention programs are in demand. METHODS This pilot study used a mixed methods design to evaluate the feasibility of an Internet-based, electronic Outpatient Cardiac Rehabilitation (eOCR). Patients who had suffered a cardiac event and their case managers were recruited from rural primary practices. Feasibility was evaluated in terms of the number of patients enrolled and patient and case manager engagement with the eOCR website. RESULTS Four rural general practices, 16 health professionals (cardiologists, general practitioners, nurses and allied health) and 24 patients participated in the project and 11 (46%) completed the program. Utilisation of the website during the 105 day evaluation period by participating health professionals was moderate to low (mean of 8.25 logins, range 0-28 logins). The mean login rate for patients was 16 (range 1-77 logins), mean time from first login to last (days using the website) was 51 (range 1-105 days). Each patient monitored at least five risk factors and read at least one of the secondary prevention articles. There was low utilisation of other tools such as weekly workbooks and discussion boards. CONCLUSIONS It was important to evaluate how an eOCR website would be used within an existing healthcare setting. These results will help to guide the implementation of future internet based cardiac rehabilitation programs considering barriers such as access and appropriate target groups of participants.

Assessing agreement between point of care and laboratory results for lipid testing from a clinical perspective.

OBJECTIVES Investigate agreement between lipid pathology results from point-of-care testing (PoCT) devices and laboratories. DESIGN AND METHODS Agreement was assessed using the Bland-Altman method. RESULTS : Mean difference (limits of agreement) were: -0.28 mmol/L (-1.04, 0.48) for total cholesterol, -0.09 mmol/L, (-0.55, 0.36) for HDL-C. Median difference (nonparametric limits of agreement) were 0.07 mmol/L, (-0.40, 3.04) for triglycerides. CONCLUSIONS The clinical acceptability of the variation between lipid PoCT and laboratory test results is debatable but our work provides baseline data for further research.

Development of an accreditation program for Point of Care Testing (PoCT) in general practice.

OBJECTIVES To describe the development and evaluation of an accreditation program for Point of Care Testing (PoCT) in general practice, which was part of the PoCT in general practice (GP) Trial conducted in 2005-07 and funded by the Australian Government. SETTING AND PARTICIPANTS Thirty general practices based in urban, rural and remote locations across South Australia, New South Wales and Victoria, which were in the intervention arm of the PoCT Trial were part of the accreditation program. A PoCT accreditation working party was established to develop an appropriate accreditation program for PoCT in GP. A multidisciplinary accreditation team was formed consisting of a medical scientist, a general practitioner or practice manager, and a trial team representative. METHODOLOGY AND SEQUENCE OF EVENTS: To enable practices to prepare for accreditation a checklist was developed describing details of the accreditation visit. A guide for surveyors was also developed to assist with accreditation visits. Descriptive analysis of the results of the accreditation process was undertaken. OUTCOMES Evaluation of the accreditation model found that both the surveyors and practice staff found the process straightforward and clear. All practices (i.e. 100%) achieved second-round accreditation. DISCUSSION AND LESSONS LEARNED The accreditation process highlighted the importance of ongoing education and support for practices performing PoCT.
