Abstract
BACKGROUND AND AIMS Knowledge of quantifiable cardiovascular disease (CVD) risk may improve health outcomes and trigger behavioural change in patients or clinicians. This review aimed to investigate the impact of CVD risk communication on patient-perceived CVD risk and changes in CVD risk factors. METHODS PubMed, Embase, and PsycINFO databases were searched from inception to 6 June 2023, supplemented by citation analysis. Randomized trials that compared any CVD risk communication strategy versus usual care were included. Paired reviewers independently screened the identified records and extracted the data; disagreements were resolved by a third author. The primary outcome was the accuracy of risk perception. Secondary outcomes were clinician-reported changes in CVD risk, psychological responses, intention to modify lifestyle, and self-reported changes in risk factors and clinician prescribing of preventive medicines. RESULTS Sixty-two trials were included. Accuracy of risk perception was higher among intervention participants (odds ratio = 2.31, 95% confidence interval = 1.63 to 3.27). A statistically significant improvement in overall CVD risk scores was found at 6-12 months (mean difference = -0.27, 95% confidence interval = -0.45 to -0.09). For primary prevention, risk communication significantly increased self-reported dietary modification (odds ratio = 1.50, 95% confidence interval = 1.21 to 1.86) with no increase in intention or actual changes in smoking cessation or physical activity. A significant impact on patients' intention to start preventive medication was found for primary and secondary prevention, with changes at follow-up for the primary prevention group. CONCLUSIONS In this systematic review and meta-analysis, communicating CVD risk information, regardless of the method, reduced the overall risk factors and enhanced patients' self-perceived risk. Communication of CVD risk to patients should be considered in routine consultations.

Heliyon 2023; 9:e19178. [PMID: 37636382 PMCID: PMC10458331 DOI: 10.1016/j.heliyon.2023.e19178] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 08/10/2023] [Accepted: 08/15/2023] [Indexed: 08/29/2023] Open
Abstract
Following Ghana's decentralisation policy, the District Assemblies, in consultation with communities, are required to prepare and implement Medium-Term Development Plans [MTDPs] to ensure the overall development of their respective jurisdictions. However, little consideration has been given to the participation of grassroots stakeholders in the development of MTDPs. Consequently, this study investigates the participation of grassroots stakeholders in developing MTDPs. A cross-sectional survey involving 139 respondents was deployed. The data were gathered using a questionnaire and an interview guide, and it was analyzed using descriptive statistics, Spearman's Rank Correlation, and thematic analysis. Results indicated that grassroots stakeholders were aware of their right to participate in the preparation of MTDPs. As such, they actively participated in the process that led to developing such plans addressing community needs. Additionally, awareness of MTDP, involvement, level of influence, satisfaction with the preparation of MTDPs, satisfaction with the quality of participation in the area council, level of confidence in the preparation of MTDP, representation adequacy, and capture of community needs had statistically significant associations at the 1% level with the associations being positive. Nonetheless, the implementation of MTDPs is jeopardised by limited funding, stakeholder commitment, and human capacity. To ensure the smooth implementation of the MTDPs, the Assembly must intensify its revenue mobilisation efforts, depoliticise the MTDP process, and build staff capacity on the involvement of the grassroots stakeholders.

Abstract
Land formalisation and commoditisation are influencing peri-urban growth in secondary cities. This notwithstanding, studies on peri-urbanisation have not prioritized secondary cities and how land transactions shape city expansion and engender livelihood diversification. Few perspectives in urban theory and practice are derived from such secondary cities, while trajectories indicate that such cities are becoming the new face of urbanisation in the Global South. Drawing evidence from Wa, Ghana, the study explores the dynamics of peri-urbanisation, and livelihood diversification through the lenses of land formalisation and a sustainable livelihood framework. Primary data were sourced from randomly selected households using questionnaires together with key informant interviews, focus group discussions and observation. To understand the spatial characteristics of peri-urban areas, Landsat satellite data were employed in analysing the land use land cover (LULC) change in Wa Municipality from 1986 to 2019. Descriptive statistics, thematic analysis and content analysis were deployed to analyse the quantitative and qualitative primary data gathered. The findings show substantial physical urban development and transition from the inner urban enclave into the periphery from the 1980s–2010s. The observed urban transformation was primarily motivated by land sales in the peri-urban areas. Despite the significant land conversion from agricultural to other uses, it was revealed that farming remained an integral livelihood activity for peri-urban households. The results indicate that embracing and applying the ideals of negotiated planning will be imperative in shaping the sustainable transformation in secondary cities.

Abstract
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.

Abstract
OBJECTIVES To evaluate the effectiveness of interventions used to support self-management, and to explore patients' experiences after acute coronary syndrome in relation to self-management. DESIGN Scoping review. DATA SOURCES Keyword search of CINAHL Plus, Medline, the Cochrane Library, and PsycINFO databases for studies conducted with adult population and published in English between 1993 and 2014. REVIEW METHODS From title and abstract review, duplicated articles and obviously irrelevant studies were removed. The full texts of the remaining articles were assessed against the selection criteria. Studies were included if they were original research on: (1) effectiveness of self-management interventions among individuals following acute coronary syndrome; or (2) patients' experience of self-managing recovery from acute coronary syndrome. RESULTS 44 articles (19 quantitative and 25 qualitative) were included. Most studies were conducted in western countries and quantitative studies were UK centric. Self-management interventions tended to be complex and include several components, including education and counselling, goal setting and problem solving skills which were mainly professional-led rather than patient-led. The review demonstrated variation in the effectiveness of self-management interventions in main outcomes assessed - anxiety and depression, quality of life and health behavioural outcomes. For most participants in the qualitative studies, acute coronary syndrome was unexpected and the recovery trajectory was a complex process. Experiences of making adjustment and adopting lifestyle changes following acute coronary syndrome were influenced by subjective life experiences and individual, sociocultural and environmental contexts. Participants' misunderstandings, misconceptions and confusion about disease processes and management were another influential factor. They emphasised a need for ongoing input and continued support from health professionals in their self-management of rehabilitation and recovery, particularly during the initial recovery period following hospital discharge. CONCLUSIONS Evidence of the effectiveness of self-management interventions among people with acute coronary syndrome remains inconclusive. Findings from the patients' experiences in relation to self-management following acute coronary syndrome provided important insights into what problems patients might have encountered during self-managing recovery and what support they might need, which can be used to inform the development of self-management interventions. Theoretical or conceptual frameworks have been minimally employed in these studies and should be incorporated in future development and evaluation of self-management interventions as a way of ensuring clarity and consistency related to how interventions are conceptualised, operationalised and empirically studied. Further research is needed to evaluate self-management interventions among people following acute coronary syndrome for sustained effect and within different health care contexts.

Abstract
PURPOSE The transtheoretical model (TTM) was used to provide tailored nursing for lifestyle management such as diet, physical activity, and smoking cessation. The present study aims to assess the provision of intervention delivery methods, intervention elements, and stage-matched interventions, in order to identify ways in which information technology is used in the TTM-based research. METHODS The relevant literature was selected by two researchers using inclusion criteria after searching for "TTM (transtheoretical or stage of change)" and "nursing" from the databases PubMed and CINAHL. The selected studies were categorized in terms of study characteristics, intervention delivery method, intervention element, and use and level of stage-matched intervention. RESULTS A total of 35 studies were selected including eight studies that used information communication technology (ICT). Nine different intervention delivery methods were used, of which "face-to-face" was the most common at 24 times. Of the 35 studies, 26 provided stage-matched interventions. Seven different intervention elements were used, of which "counseling" was the most common at 27 times. Of all the intervention elements, tailored feedback used ICT the most at seven instances out of nine, and there was a significant difference in the rate of ICT usage among intervention elements. CONCLUSIONS ICT is not yet actively used in the TTM-based nursing interventions. Stage-matched interventions and TTM concepts were shown to be in partial use also in the TTM-based interventions. Therefore, it is necessary to develop a variety of ways to use ICT in tailored nursing interventions and to use TTM frameworks and concepts.

Abstract
We conducted a literature review of telerehabilitation interventions on cardiac patients. We searched for studies evaluating some form of telerehabilitation in cardiac patients. A total of 116 publications were screened initially, of which 37 publications were eligible for further review. We assessed study strength, based on the level of evidence and the quality of the intervention. The majority of the articles (70%) represented the highest level of evidence. Most interventions were of good (46%) or fair (51%) quality. Most studies evaluated the efficacy of the telerehabilitation interventions (84%), while 38% reported on feasibility and acceptance. Most studies did not include safety and/or cost-benefit analyses. Most telerehabilitation interventions (90%) employed only one or two core components of cardiac rehabilitation (CR). Of the CR core components, physical activity was most frequently evaluated. Telerehabilitation appears to be a feasible and effective additional and/or alternative form of rehabilitation, compared to conventional in-hospital CR. Evaluations of telerehabilitation programmes taking into account patient safety and health economics are now required.

Abstract
BACKGROUND Obesity is a global public health threat. The transtheoretical stages of change (TTM SOC) model has long been considered a useful interventional approach in lifestyle modification programmes, but its effectiveness in producing sustainable weight loss in overweight and obese individuals has been found to vary considerably. OBJECTIVES To assess the effectiveness of dietary intervention or physical activity interventions, or both, and other interventions based on the transtheoretical model (TTM) stages of change (SOC) to produce sustainable (one year and longer) weight loss in overweight and obese adults. SEARCH METHODS Studies were obtained from searches of multiple electronic bibliographic databases. We searched The Cochrane Library, MEDLINE, EMBASE and PsycINFO. The date of the last search, for all databases, was 17 December 2013. SELECTION CRITERIA Trials were included if they fulfilled the criteria of randomised controlled clinical trials (RCTs) using the TTM SOC as a model, that is a theoretical framework or guideline in designing lifestyle modification strategies, mainly dietary and physical activity interventions, versus a comparison intervention of usual care; one of the outcome measures of the study was weight loss, measured as change in weight or body mass index (BMI); participants were overweight or obese adults only; and the intervention was delivered by healthcare professionals or trained lay people at the hospital and community level, including at home. DATA COLLECTION AND ANALYSIS Two review authors independently extracted the data, assessed studies for risk of bias and evaluated overall study quality according to GRADE (Grading of Recommendations Assessment, Development and Evaluation). We resolved disagreements by discussion or consultation with a third party. A narrative, descriptive analysis was conducted for the systematic review. MAIN RESULTS A total of three studies met the inclusion criteria, allocating 2971 participants to the intervention and control groups. The total number of participants randomised to the intervention groups was 1467, whilst 1504 were randomised to the control groups. The length of intervention was 9, 12 and 24 months in the different trials. The use of TTM SOC in combination with diet or physical activity, or both, and other interventions in the included studies produced inconclusive evidence that TTM SOC interventions led to sustained weight loss (the mean difference between intervention and control groups varied from 2.1 kg to 0.2 kg at 24 months; 2971 participants; 3 trials; low quality evidence). Following application of TTM SOC there were improvements in physical activity and dietary habits, such as increased exercise duration and frequency, reduced dietary fat intake and increased fruit and vegetable consumption (very low quality evidence). Weight gain was reported as an adverse event in one of the included trials. None of the trials reported health-related quality of life, morbidity, or economic costs as outcomes. The small number of studies and their variable methodological quality limit the applicability of the findings to clinical practice. The main limitations include inadequate reporting of outcomes and the methods for allocation, randomisation and blinding; extensive use of self-reported measures to estimate the effects of interventions on a number of outcomes, including weight loss, dietary consumption and physical activity levels; and insufficient assessment of sustainability due to lack of post-intervention assessments. AUTHORS' CONCLUSIONS The evidence to support the use of TTM SOC in weight loss interventions is limited by risk of bias and imprecision, not allowing firm conclusions to be drawn. When combined with diet or physical activity, or both, and other interventions we found very low quality evidence that it might lead to better dietary and physical activity habits. This systematic review highlights the need for well-designed RCTs that apply the principles of the TTM SOC appropriately to produce conclusive evidence about the effect of TTM SOC lifestyle interventions on weight loss and other health outcomes.

Abstract
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.

Abstract
Sample size is an element of research design that significantly affects the validity and clinical relevance of the findings identified in research studies. Factors that influence sample size include the effect size, or difference expected between groups or time points, the homogeneity of the study participants, the risk of error that investigators consider acceptable and the rate of participant attrition expected during the study. Appropriate planning in regard to each of these elements optimises the likelihood of finding an important result that is both clinically and statistically meaningful.

Abstract
BACKGROUND As lifestyle adherence and risk factor management following completion of cardiac rehabilitation (CR) have been shown to be problematic, we developed a brief self-regulation lifestyle programme for post-CR patients. DESIGN Randomized-controlled trial. METHODS Following completion of CR 210 patients were randomized to receive either a lifestyle maintenance programme (n = 112) or standard care (n = 98). The programme was based on self-regulation principles and consisted of a motivational interview, seven group sessions, and home assignments. Risk factors and health behaviours were assessed at baseline (end of CR) and 6 months thereafter. RESULTS ANCOVAs showed a significant effect of the lifestyle programme after 6 months on blood pressure, waist circumference, and exercise behaviour. CONCLUSION This trial indicates that a relatively brief intervention based on self-regulation theory is capable of instigating and maintaining beneficial changes in lifestyle and risk factors after CR.

Abstract
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.

Abstract
BACKGROUND Obesity is a global public health threat. The transtheoretical model stages of change (TTM SOC) model has long been considered a useful interventional approach in lifestyle modification programmes, but its effectiveness in producing sustainable weight loss in overweight and obese individuals has been found to vary considerably. OBJECTIVES To assess the effectiveness of dietary and physical activity interventions based on the transtheoretical model, to produce sustainable weight loss in overweight and obese adults. SEARCH STRATEGY Studies were obtained from searches of multiple electronic bibliographic databases. Date of last search for The Cochrane Library was issue 10, 2010, for MEDLINE Dezember 2010, for EMBASE January 2011 and for PSYCHINFO Januar 2011. SELECTION CRITERIA Trials were included if they fulfilled the following criteria: randomised controlled clinical trials using TTM SOC as a model, theoretical framework or guideline in designing lifestyle modification strategies, mainly dietary and physical exercise versus a comparison intervention of usual care; one of the outcome measures of the study was weight loss; and participants were overweight or obese adults. DATA COLLECTION AND ANALYSIS Two researchers independently applied the inclusion criteria to the identified studies and assessed risk of bias. Disagreement was resolved by discussion or by intervention of a third party. Descriptive analysis was conducted for the review. MAIN RESULTS A total of five studies met the inclusion criteria and a total of 3910 participants were evaluated. The total number of participants randomised to intervention groups was 1834 and 2076 were randomised to control groups. Overall risk of bias was high. The trials varied in length of intervention from six weeks to 24 months, with a median length of nine months. The intervention was found to have limited impact on weight loss (about 2 kg or less) and other outcome measures. There was no conclusive evidence for sustainable weight loss. However, TTM SOC and a combination of physical activity, diet and other interventions tended to produce significant outcomes (particularly change in physical activity and dietary intake). TTM SOC was used inconsistently as a theoretical framework for intervention in the trials. Death and weight gain are the two adverse events reported by the included trials. None of the trials reported health-related quality of life, morbidity, and costs as outcomes. AUTHORS' CONCLUSIONS TTM SOC and a combination of physical activity, diet and other interventions resulted in minimal weight loss, and there was no conclusive evidence for sustainable weight loss. The impact of TTM SOC as theoretical framework in weight loss management may depend on how it is used as a framework for intervention and in combination with other strategies like diet and physical activities.

Abstract
BACKGROUND Nurse-led telephone follow-up offers a relatively inexpensive method of delivering education and support for assisting recovery in the early discharge period; however, its efficacy is yet to be determined. AIM To perform a critical integrative review of the research literature addressing the effectiveness of nurse-led telephone interventions for people with coronary heart disease (CHD). METHODS A literature search of five health care databases; Sciencedirect, Cumulative Index to Nursing and Allied Health Literature, Pubmed, Proquest and Medline to identify journal articles between 1980 and 2009. People with cardiac disease were considered for inclusion in this review. The search yielded 128 papers, of which 24 met the inclusion criteria. RESULTS A total of 8330 participants from 24 studies were included in the final review. Seven studies demonstrated statistically significant differences in all outcomes measured, used two group experimental research design and valid and reliable instruments. Some positive effects were detected in eight studies in regards to nurse-led telephone interventions for people with cardiac disease and no differences were detected in nine studies. DISCUSSION Studies with some positive effects generally had stronger research designs, large samples, used valid and reliable instruments and extensive nurse-led educative interventions. CONCLUSION The results suggest that people with cardiac disease showed some benefits from nurse-led/delivered telephone interventions. More rigorous research into this area is needed.
