The effect of community-based health management on the health of the elderly: a randomized controlled trial from China

Preventive interventions to improve older people's health outcomes: systematic review and meta-analysis

BACKGROUND

Systematic reviews of preventive, non-disease-specific primary care trials for older people often report effects according to what is thought to be the intervention's active ingredient.

AIM

To examine the effectiveness of preventive primary care interventions for older people and to identify common components that contribute to intervention success.

DESIGN AND SETTING

A systematic review and meta-analysis of 18 randomised controlled trials (RCTs) published in 22 publications from 2009 to 2019.

METHOD

A search was conducted in PubMed, MEDLINE, Embase, Web of Science, CENTRAL, CINAHL, and the Cochrane Library. Inclusion criteria were: sample mainly aged ≥65 years; delivered in primary care; and non-disease-specific interventions. Exclusion criteria were: non-RCTs; primarily pharmacological or psychological interventions; and where outcomes of interest were not reported. Risk of bias was assessed using the original Cochrane tool. Outcomes examined were healthcare use including admissions to hospital and aged residential care (ARC), and patient-reported outcomes including activities of daily living (ADLs) and self-rated health (SRH).

RESULTS

Many studies had a mix of patient-, provider-, and practice-focused intervention components (13 of 18 studies). Studies included in the review had low-to-moderate risk of bias. Interventions had no overall benefit to healthcare use (including admissions to hospital and ARC) but higher basic ADL scores were observed (standardised mean difference [SMD] 0.21, 95% confidence interval [CI] = 0.01 to 0.40) and higher odds of reporting positive SRH (odds ratio [OR] 1.17, 95% CI = 1.01 to 1.37). When intervention effects were examined by components, better patient-reported outcomes were observed in studies that changed the care setting (SMD for basic ADLs 0.21, 95% CI = 0.01 to 0.40; OR for positive SRH 1.17, 95% CI = 1.01 to 1.37), included educational components for health professionals (SMD for basic ADLs 0.21, 95% CI = 0.01 to 0.40; OR for positive SRH 1.27, 95% CI = 1.05 to 1.55), and provided patient education (SMD for basic ADLs 0.28, 95% CI = 0.09 to 0.48). Additionally, admissions to hospital in intervention participants were fewer by 23% in studies that changed the care setting (incidence rate ratio [IRR] 0.77, 95% CI = 0.63 to 0.95) and by 26% in studies that provided patient education (IRR 0.74, 95% CI = 0.56 to 0.97).

CONCLUSION

Preventive primary care interventions are beneficial to older people's functional ability and SRH but not other outcomes. To improve primary care for older people, future programmes should consider delivering care in alternative settings, for example, home visits and phone contacts, and providing education to patients and health professionals as these may contribute to positive outcomes.

Addressing pressures on health services in Belo Horizonte, Brazil through community-based care for poor older people: a qualitative study

Background

In low and middle-income countries, there is growing interest in managing pressures on health services through community interventions for older people. Evidence on the effects of such interventions is scarce. We draw on qualitative data to examine these effects for a specific scheme, Programa Maior Cuidado (PMC) in the Brazilian city of Belo Horizonte.

Methods

Building on quantitative findings reported elsewhere, we use qualitative data to develop and test theories of change. These include data from 50 meetings with policymakers, managers and staff in 30 health centres and social assistance posts. Data collection was embedded in key informant interaction and knowledge coproduction. Data include participant and non-participant observation, focus groups and semi-structured interviews with key informants, as well as older people and carers from seven families.

Findings

The data reveal three theories of change. Theory 1 is PMC maintains older people's health which reduces their need for inpatient or outpatient care. We find strong evidence to support this, through effects on use of medication, chronic disease management and risk prevention. Theory 2 is PMC promotes timely intervention by anticipating health problems, thus reducing demand for emergency and acute care. We find some evidence for this, but it was limited by limited availability of timely treatment or referral beyond PMC. Theory 3 is PMC facilitates hospital discharge. We find limited evidence for this, reflecting a lack of formal liaison between PMC and hospitals.

Interpretation

Schemes like PMC have potential to reduce pressures on health service utilisation by older people, if they are well articulated with wider health services.

Dietary outcomes of community-based CVD preventive interventions: a systematic review and meta-analysis

OBJECTIVE

We aimed to synthesise available evidence on the effects of community-based interventions in improving various dietary outcome measures.

DESIGN

Systematic review and meta-analysis.

SETTING

We searched databases including Medline, EMBASE, PSYCINFO, CINAHL and the Cochrane registry for studies reported between January 2000 and June 2022. The methodological quality of the included studies was evaluated using the Cochrane risk of bias tools for each study type. For some of the outcomes, we pooled the effect size using a random-effects meta-analysis.

PARTICIPANTS

A total of fifty-one studies, thirty-three randomised and eighteen non-randomised, involving 100 746 participants were included.

RESULTS

Overall, thirty-seven studies found a statistically significant difference in at least one dietary outcome measure favouring the intervention group, whereas fourteen studies found no statistically significant difference. Our meta-analyses indicated that, compared with controls, interventions were effective in decreasing daily energy intake (MJ/d) (mean difference (MD): -0·25; 95 % CI: -0·37, -0·14), fat % of energy (MD: -1·01; 95 % CI: -1·76, -0·25) and saturated fat % of energy (MD: -1·54; 95 % CI: -2·01, -1·07). Furthermore, the interventions were effective in improving fibre intake (g/d) (MD: 1·08; 95 % CI: 0·39, 1·77). Effective interventions use various strategies including tailored individual lifestyle coaching, health education, health promotion activities, community engagement activities and/or structural changes.

CONCLUSION

This review shows the potential of improving dietary patterns through community-based CVD preventive interventions. Thus, development and implementation of context-specific preventive interventions could help to minimise dietary risk factors, which in turn decrease morbidity and mortality due to CVD and other non-communicable diseases.

Home/Community-Based Medical and Elderly Care Services Utilization in China: A Cross-Sectional Study from the Middle-Aged and Elderly Population

Few studies have analyzed the acceptance of home/community-based medical and elderly care services in China. Therefore, we conducted a cross-sectional study to describe the acceptance of five services among people aged ≥ 45 years in the China mainland, and their influencing factors. The data were obtained from the database China Health and Retirement Longitudinal Study 2018. For each service, a binary logistics regression was adopted. A total of 9719 people were included, of whom 20.12% received services. The numbers of recipients (acceptance rates) of the five services, namely, comprehensive aged care services, regular physical examinations, onsite visits, health management, and entertainment, were 107 (1.10%), 1640 (16.87%), 323 (3.32%), 156 (1.61%), and 245 (2.52%), respectively. About 4% of people had received two or more services. The elderly aged 65-74 and those who were satisfied with the local medical services had higher acceptance of services. Urban hukou having health insurance, two or more chronic diseases, provincial economic welfare, and social welfare were positively associated with the acceptance of regular physical examination services. It is suggested that the government should gradually improve satisfaction with local medical services, and pay more attention to the needs of elderly people aged 65-74 for all kinds of home/community-based medical and elderly care services.

The impact of home and community care services pilot program on healthy aging: A difference-in-difference with propensity score matching analysis from China

BACKGROUND

Home and community care service (HACCS) is an important policy response worldwide to the growing and unmet care needs of the aging population. In China, the government also started to implement a HACCS pilot program in 2016. This study aims to evaluate the association of HACCS utilization with healthy aging in Chinese older adults.

METHODS

This study followed a quasi-experimental design and derived data from the nationwide China Health and Retirement Longitudinal Study (CHARLS) in 2015 and 2018. We employed the propensity score matching with difference-in-difference approach (PSM-DID) to examine the association between HACCS and healthy aging indicators.

RESULTS

A total of 8345 older adults were incorporated for a final sample. The results indicated that HACCS utilization was associated with significantly reduced functional limitations (β for BADL=-0.124, β for IADL=-0.210; P<0.01) and depression (β=-0.386, P<0.05) as well as improved cognitive function (β=0.609, P<0.001), life satisfaction (β=0.083, P<0.01) and social participation (β=0.105, P<0.01) in older people, although its association with reduced disability was non-significant (β=-0.005, P = 0.676). The heterogeneous tests further found that rural older adults and older adults aged<80 were more likely than their counterparts to benefit from the HACCS utilization in specific healthy aging indicators such as cognitive function.

CONCLUSIONS

The implementation of the HACCS program benefited a range of healthy aging domains among older adults in China. Policymakers are encouraged to further expand the program implementation and also continue to improve the services list and care quality of HACCS.

Type and effectiveness of community-based interventions in improving knowledge related to cardiovascular diseases and risk factors: A systematic review

Background: Despite an improvement in the healthcare system, cardiovascular diseases (CVDs) remain the leading cause of morbidity and mortality worldwide. Improving knowledge is a key for behavioral change towards prevention of CVDs. However, up-to-date evidence is limited on the effect of interventions on CVD knowledge. Thus this study aimed to synthesize comprehensive evidence on the type and effectiveness of community-based interventions (CBIs) to improve knowledge related to CVDs. Methods: We performed a systematic review of studies that tested the effectiveness of CBIs in improving CVD knowledge. International databases including MEDLINE, EMBASE, CINAHL, PSYCINFO and Cochrane register of controlled studies were searched for studies published between January 2000 and December 2019. The Cochrane risk of bias tools were used to assess the methodological quality of included studies. Since CVD knowledge was measured using various tools, results were synthesized narratively and reported in line with the reporting guideline for Synthesis Without Meta-analysis (SWiM). The review protocol is registered in the PROSPERO database (CRD42019119885). Results: 7 randomized and 9 non-randomized controlled trials involving 34,845 participants were included. Most of the interventions targeted the general population and majorities delivered the intervention to groups of individuals. Likewise, most of the interventions employed various intervention components including health education using different strategies. Overall, most studies showed that CBIs significantly improved knowledge related to CVDs. Conclusion: Community-based CVD preventive interventions are effective in improving knowledge related to CVD and risk factors. Measures to scale up CBIs are recommended to improve an individual's level of CVD knowledge, which potentially helps to counter the growing burden of CVDs.

Determining the frequency and level of task-sharing for hypertension management in LMICs: A systematic review and meta-analysis

BACKGROUND

Low- and middle-income countries (LMICs) bear a disproportionately higher burden of Cardiovascular Disease (CVD). Team-based care approach adds capacity to improve blood pressure (BP) control. This updated review aimed to test team-based care efficacy at different levels of hypertension team-based care complexity.

METHODS

We searched PubMed, Embase, Cochrane, and CINAHL for newer articles on task-sharing interventions to manage hypertension in LMICs. Levels of tasks complexity performed by healthcare workers added to the clinical team in hypertension control programs were categorized as administrative tasks (level 1), basic clinical tasks (level 2), and/or advanced clinical tasks (level 3). Meta-analysis using an inverse variance weighted random-effects model summarized trial-based evidence on the efficacy of team-based care on BP control, compared with usual care.

FINDINGS

Forty-three RCT articles were included in the meta-analysis: 31 studies from the previous systematic review, 12 articles from the updated search. The pooled mean effect for team-based care was a -4.6 mm Hg (95% CI: -5.8, -3.4, I²  = 80.2%) decrease in systolic BP compared with usual care. We found similar comparative reduction among different levels of team-based care complexity, i.e., administrative and basic clinical tasks (-4.7 mm Hg, 95% CI: -6.8, -2.2; I²  = 79.8%); and advanced clinical tasks (-4.5 mmHg, 95%CI: -6.1, -3.3; I²  = 81%). Systolic BP was reduced most by team-based care involving pharmacists (-7.3 mm Hg, 95% CI: -9.2, -5.4; I²  = 67.2%); followed by nurses (-5.1 mm Hg, 95% CI: -8.0, -2.2; I²  = 72.7%), dieticians (-4.7 mmHg, 95%CI: -7.1, -2.3; I²  = 0.0%), then community health workers (-3.3 mm Hg, 95% CI: -4.8, -1.8; I²  = 77.3%).

INTERPRETATION

Overall, team-based hypertension care interventions consistently contributed to lower systolic BP compared to usual care; the effect size varies by the clinical training of the healthcare team members.

Effectiveness of community-based cardiovascular disease prevention interventions to improve physical activity: A systematic review and meta-regression

Cardiovascular diseases (CVDs) remain a leading cause of morbidity and mortality globally. Despite preventive community-based interventions (CBIs) seem efficacious in reducing CVD risks, a comprehensive up-to-date synthesis on the effectiveness of such interventions in improving physical activity (PA) is lacking. We performed a systematic review and meta-analysis of community-based CVD preventive interventions aimed at improving PA level. MEDLINE, EMBASE, CINAHL, Cochrane register and PSYCINFO databases were searched in October 2019 for studies reported between January 2000 and June 2019. We assessed the methodological quality of included studies using the Cochrane risk of bias tools. We performed a random-effects meta-analysis and meta-regression to pool estimates of various effect measures. Results are reported in line with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guideline. Our study protocol was registered in the PROSPERO database (CRD42019119885). A total of 44 randomized and 20 non-randomized controlled studies involving 98,919 participants were included. Meta-analyses found that CBIs improved the odds of attaining the recommended PA level (at least 150 min of moderate and vigorous PA (MVPA)/week) at 12 month (OR: 1.62; 95%CI: 1.25-2.11) and 18 to 24 months of follow-up (OR: 1.46; 95%CI: 1.12-1.91). Furthermore, interventions were effective in improving metabolic equivalents of task at 12 month (standardized mean difference (SMD): 0.28; 95% CI: 0.03-0.53), MVPA time at 12 to 18 months (SMD: 0.34; 95%CI: 0.05-0.64), steps per day (SMD: 0.32; 95%CI: 0.08-0.55), and sitting time (SMD: -0.25; 95%CI: -0.34 to -0.17). Subgroup analyses found that interventions in low- and middle-income countries showed a greater positive effect on attainment of recommended PA level (OR: 1.40; 95%CI: 1.02-1.92) than those in high-income countries (OR: 1.31; 95%CI: 0.96-1.78). Moreover, interventions targeting high-risk groups showed greater effectiveness than those targeting the general population (OR: 1.76; 95%CI: 1.30-2.39 vs. 1.17; 95%CI: 0.89-1.55). In conclusion, community-based CVD preventive interventions have a positive impact on improving the PA level, albeit that relevant studies in lower-middle and low-income countries are limited. With the rising burden of CVDs, rolling out CBIs targeting the general population and high-risk groups are needed to control the growing CVD-burden.

Community-Based Interventions for Cardiovascular Disease Prevention in Low-and Middle-Income Countries: A Systematic Review

Objectives: To synthesize evidence on the effectiveness of community-based interventions for cardiovascular disease (CVD) prevention in low- and middle-income countries (LMICs) to inform design of effective strategies for CVD prevention. Methods: We searched MEDLINE, EMBASE, CINAHL, Cochrane register of controlled studies and PSYCINFO databases for studies published between January 2000 and June 2019. Other studies were identified from gray literature sources and review of reference lists of included studies. The primary outcomes for the review were those aimed at primary prevention of CVD targeting physical activity, diet, smoking and alcohol consumption. Results: Database searches yielded 15,885 articles and 94 articles were identified through snowball searching. After screening, the articles from LMICs were 32 emanating from 27 studies: 9 cluster randomized trials, eight randomized controlled trials and 10 controlled before and after studies. Community-based interventions successfully improved population knowledge on CVD and risk factors and influenced physical activity and dietary practices. Evidence of interventions on smoking cessation and reduced alcohol consumption was inconsistent. Conclusion: This evidence should inform policy makers in decision-making and prioritizing evidence-based interventions.

Effectiveness of a Female Community Health Volunteer-Delivered Intervention in Reducing Blood Glucose Among Adults With Type 2 Diabetes: An Open-Label, Cluster Randomized Clinical Trial

IMPORTANCE

Female community health volunteers (FCHVs) are frontline community health workers who have been a valuable resource in improving public health outcomes in Nepal, but their value is understudied in diabetes care.

OBJECTIVE

To assess whether an FCHV-delivered intervention is associated with reduced blood glucose levels among adults with type 2 diabetes.

DESIGN, SETTING, AND PARTICIPANTS

This community-based, open-label, 2-group, cluster randomized clinical trial with a 12-month delayed control group design was conducted in 14 clusters of a semiurban setting in Western Nepal. A total of 244 adults with type 2 diabetes were recruited between November 2016 and April 2017. The follow-up assessment was conducted at 12 months after enrollment. Data analysis was performed from January to February 2019.

INTERVENTIONS

Seven clusters were randomized to the FCHV-delivered intervention in which 20 FCHVs provided home visits 3 times a year (once every 4 months) for health promotion counseling and blood glucose monitoring. If participants had blood glucose levels of 126 mg/dL or higher, the FCHVs referred them to the nearest health facility, and if participants were taking antihyperglycemic medication, they were followed up by the FCHVs for adherence to their medication. Seven clusters were randomized to usual care (control group).

MAIN OUTCOMES AND MEASURES

The primary outcome was the change in mean fasting blood glucose from baseline to 12-month follow-up. Secondary outcomes included changes in mean systolic blood pressure, mean diastolic blood pressure, mean body mass index, percentage change in the proportion of low physical activity, harmful alcohol consumption, current smoking, low fruit and vegetable intake, and antihyperglycemic medication status.

RESULTS

Of 244 participants, 120 women (56.6%) and 92 men (43.4%) completed the trial. At baseline, the mean (SD) age was 51.71 (8.77) years; 127 participants were in the intervention group, and 117 participants were in the control group (usual care). At baseline, the mean (SD) fasting blood glucose level was 156.06 (44.48) mg/dL (158.48 [45.50] mg/dL in the intervention group and 153.43 [43.39] mg/dL in the control group). At 12-month follow-up, the mean fasting blood glucose decreased by 22.86 mg/dL in the intervention group, whereas it increased by 7.38 mg/dL in the control group. The mean reduction was 27.90 mg/dL greater with the intervention (95% CI, -37.62 to -18.18 mg/dL; P < .001). In secondary outcome analyses, there was a greater decline in mean systolic blood pressure in the intervention group than in the control group (-5.40 mm Hg; 95% CI, -8.88 to -1.92 mm Hg; P = .002). There was detectable difference in the intake of antihyperglycemic medication between the groups (relative risk, 1.35; 95% CI, 1.1 to 1.74; P = .02).

CONCLUSIONS AND RELEVANCE

These findings suggest that an FCHV-delivered intervention is associated with reduced blood glucose levels among adults with type 2 diabetes in a low-resource setting in Nepal.

Task-sharing interventions for improving control of diabetes in low-income and middle-income countries: a systematic review and meta-analysis

Background

Task-sharing interventions using non-physician health-care workers might be a potential diabetes management strategy in health systems that are constrained by physician shortages, such as those in low-income and middle-income countries (LMICs).

Methods

We did a systematic review and meta-analysis of task-sharing intervention strategies for managing type 2 diabetes in LMICs. We searched PubMed, Embase, and CINAHL from database inception to Sept 25, 2019, for studies that were randomised control trials or cluster randomised trials with task-shifted or task-shared interventions delivered to adults (≥18 years) by non-physician health workers versus usual care, done in LMICs with glycated haemoglobin (HbA_1c) or fasting blood sugar (FBS) as outcome measures. The methodological quality of included studies was assessed using the Cochrane risk of bias tool. Random-effects model meta-analysis was used to estimate the population average pooled mean difference for HbA_1c and FBS with 95% CIs. Our study protocol was registered in the PROSPERO database (CRD42018081015).

Findings

We found 4213 studies from the literature search, of which 46 (1·1%) were eligible for the narrative synthesis, including a total of 16 973 participants. 16 of these studies were excluded from the meta-analysis due to high risk of bias. 24 studies with a total of 5345 participants were included in the meta-analysis of HbA_1c and 18 studies with a total of 3287 participants for FBS. Interventions led to an average reduction in HbA_1c when tasks were delivered by nurses (averaged pooled mean difference −0·54% [95% CI −0·89 to −0·18]; I²=80%) and pharmacists (−0·91% [–1·15 to −0·68]; I²=58%), but not when they were delivered by dietitians (−0·50% [–1·10 to 0·09]; I²=54%) or community health workers (0·05% [0·03 to 0·07]; I²=0%). A reduction in average FBS was also observed when interventions were delivered by pharmacists (average pooled mean difference −36·26 mg/dL [–52·60 to −19·92]; I²=78%) but not nurses (−7·46 mg/dL [–18·44 to 3·52]; I²=79%) or community health workers (−5·41 [–12·74 to 1·92]; I²=71%). Only one study reported on FBS when tasks were delivered by dietitians, with a mean difference of −35·00 mg/dL (−65·96 to −4·04).

Interpretation

Task sharing interventions with non-physician healthcare workers show moderate effectiveness in diabetes management in LMIC settings. Although relatively high heterogeneity limits the interpretation of the overall findings, interventions led by pharmacists and nurses in LMICs with relatively high physician density are effective strategies in the management of diabetes.

Examining inequality in utilisation of health management services for the elderly in rural Henan China

Background

The health management plays an important role in improving the quality of life of the elderly and relieving the pressure of health resource consumption. This study aims to assess the income-related inequality in utilisation of health management services (HMS) for the elderly and the contribution of the related factors to inequality in rural Henan China.

Methods

The data from 2015 Henan Rural Residents Health Survey with 1403 elderly people as the final sample were used for analysis. The concentration index (CI) was used to measure inequality in HMS utilisation for the elderly (no HMS, health assessment, physical examination, auxiliary examination, and health guidance). The decomposition of CI was adopted to explain the contribution of various determinants to inequality in HMS utilisation for the elderly.

Results

No HMS utilisation was disproportionately concentrated among the poor (CI = − 0.0730, p = 0.0155), utilisation of physical and auxiliary examination was disproportionately concentrated among the rich (CI = 0.0575, p = 0.0448; CI = 0.0811, p = 0.0044). In addition, the pro-poor effects of health assessment and guidance utilisation were not statistically significant (CI = − 0.0173, p = 0.4617; CI = − 0.0213, p = 0.3900). The results of CI decomposition revealed that household income and family size made positive contributions to inequality while social medical insurance, gender, marital status, and age made negative contributions to inequality. The improved service satisfaction with village clinics could reduce inequality in HMS utilisation, while the improved service satisfaction with township hospitals could increase inequality in HMS utilisation.

Conclusions

Although HMS for the elderly is provided free of charge, its accessibility remains pro-rich due to various factors. Policy makers should adopt effective interventions to resolve the contradiction between these factors and the utilisation of HMS, and redress inequality in the utilisation of HMS.

Effect of Land Expropriation on Land-Lost Farmers' Health: Empirical Evidence from Rural China

With rapid urbanization and industry development, China has witnessed substantial land acquisition. Using the rural household survey data, this paper examines the impact of land expropriation on land-lost farmers’ self-reported health with the ordered probit model and investigates the possible mechanisms. The results show that the land expropriation puts higher health risks over those land-lost farmers and the health status of land-lost farmers is significantly worse than that of those with land. Land expropriation has a negative impact on the land-lost farmer’s health through income effects and psychological effects. The health status of land-lost farmers can be enhanced through amending current land requisition policies, increasing the amount of compensation, improving the earning capacity of land-lost farmers and strengthening mental health education.

Task sharing with non-physician health-care workers for management of blood pressure in low-income and middle-income countries: a systematic review and meta-analysis

BACKGROUND

Task sharing for the management of hypertension could be useful for understaffed and resource-poor health systems. We assessed the effectiveness of task-sharing interventions in improving blood pressure control among adults in low-income and middle-income countries.

METHODS

We searched the Cochrane Library, PubMed, Embase, and CINAHL for studies published up to December 2018. We included intervention studies involving a task-sharing strategy for management of blood pressure and other cardiovascular risk factors. We extracted data on population, interventions, blood pressure, and task sharing groups. We did a meta-analysis of randomised controlled trials.

FINDINGS

We found 3012 references, of which 54 met the inclusion criteria initially. Another nine studies were included following an updated search. There were 43 trials and 20 before-and-after studies. We included 31 studies in our meta-analysis. Systolic blood pressure was decreased through task sharing in different groups of health-care workers: the mean difference was -5·34 mm Hg (95% CI -9·00 to -1·67, I2=84%) for task sharing with nurses, -8·12 mm Hg (-10·23 to -6·01, I2=57%) for pharmacists, -4·67 mm Hg (-7·09 to -2·24, I2=0%) for dietitians, -3·67 mm Hg (-4·58 to -2·77, I2=24%) for community health workers, and -4·85 mm Hg (-6·12 to -3·57, I2=76%) overall. We found a similar reduction in diastolic blood pressure (overall mean difference -2·92 mm Hg, -3·75 to -2·09, I2=80%). The overall quality of evidence based on GRADE criteria was moderate for systolic blood pressure, but low for diastolic blood pressure.

INTERPRETATION

Task-sharing interventions are effective in reducing blood pressure. Long-term studies are needed to understand their potential impact on cardiovascular outcomes and mortality.

Persistent effect at 30-month post intervention of a community-based randomized trial of KM2H2 in reducing stroke and heart attack among senior hypertensive patients

BACKGROUND

The effect of the Keep Moving toward Healthy Heart and Healthy Brain (KM2H2) program at 6-month post intervention has been assessed.  The purpose of this study is to evaluate the KM2H² program at 30-month post intervention.

METHODS

A total of 450 senior hypertensive patients from 12 community health centers were randomized by center to either receive KM2H² plus standard care (6 centers, n = 232) or standard care only (6 centers, n = 218). Data for outcome measures at 30-month post intervention were analyzed. New cases of stroke and heart attack were verified with medical records; levels of physical activity were assessed using self-reported questionnaire. In addition to comparative analysis, adjusted incidence rate and program effects were determined using mixed effects modeling method.

RESULTS

At the 30-month follow-up, the adjusted incidence rate [95% CI] of stroke was 11.81% [5.90, 17.72] for patients in the intervention group and 19.78% [14.07, 25.50] (p = 0.03) for the control group. The adjusted incidence rate of heart attack was 3.34% [1.91, 8.58] and 6.68% [1.64, 11.73] for the intervention and control groups (p = 0.16), respectively; the proportion and the duration of engaging in regular physical activity were significantly greater for the intervention group than the control group. The reductions in blood pressure between the intervention and the control was not statistically significant.

CONCLUSIONS

The KM2H² program showed a persistent effect up to 30 months post intervention in enhancing physical activity and reducing the risk of cardio-cerebrovascular events, particularly stroke. These findings demonstrate the persistent effect of the KM2H² and suggest the need for a full-scale evaluation of the intervention program for practical use.

Self-Management of Multiple Chronic Conditions by Community-Dwelling Older Adults: A Concept Analysis

The proportion of the aging population living with multiple chronic conditions (MCC) is increasing. Self-management is valuable in helping individuals manage MCC. The purpose of this study was to conduct a concept analysis of self-management in community-dwelling older adults with MCC using Walker and Avant's method. The review included 30 articles published between 2000 and 2017. The following attributes were identified: (a) using financial resources for chronic disease management, (b) acquiring health- and disease-related education, (c) making use of ongoing social supports, (d) responding positively to health changes, (e) ongoing engagement with the health system, and (f) actively participating in sustained disease management. Self-management is a complex process; the presence of these attributes increases the likelihood that an older adult will be successful in managing the symptoms of MCC.

Improved Health Status and Life Satisfaction among Older People following Self-Help Group Intervention in Jakarta

Although self-help group for older people gains the effectiveness, the effect of a nursing intervention using a self-help group model as a guideline for self-monitoring and intervention on the health status and life satisfaction among older people still remains. To determine the effectiveness of this nursing intervention, an experimental design using multistage sampling method was used for this study. The self-help intervention included a single 50-70-minute session once a week for 12 weeks done, using the Life Satisfaction Inventory-A (LSI-A) questionnaire, and SF-36 shows a significant difference. Self-help intervention could be implemented by nurses for older people in the community to improve health and well-being.

Community health service center-based cardiac rehabilitation in patients with coronary heart disease: a prospective study

BACKGROUND

Despite considerable efforts to encourage participation, even in some developed countries, proportion of patients participating in institution-based cardiac rehabilitation (CR) programs remained sub-optimal. The present study was designed to investigate the acceptability of community health service center (CHSC)-based Cardiac Rehabilitation (CR), and examine its effectiveness in terms of changes in quality of life (QOL), psychological state and exercise capacity.

METHODS

A consecutive series of eligible patients was recruited from the health registration system of two CHSCs in Shijiazhuang, Hebei, China. Patients in intervention site were provided with CR (CR-group) while patients in non-intervention site were offered the usual care (UC-group). Data regarding health-related QOL (HRQoL), psychological state and exercise capacity (6-min walk test = 6MWT) were collected and compared at baseline and at 6 months post-intervention.

RESULTS

Among invited patients eligible for CR program, 65.3% participated, while 5.3% of the participants dropped out during follow-up. Patients in CR-group showed significant decrease in the scores for anxiety and depression as per the Hospital Anxiety and Depression Scale (HADS), along with marked increases in the Short-Form Health Survey (SF-12)-based Physical (PCS) and Mental Component Summary (MCS) scores. Moreover, the measurement of 6MWT showed a significant increase of 57.42 m walking distance among CR patients in contrast with a slight increase among UC patients.

CONCLUSIONS

Given the high participation and low withdrawal along with considerable improvements in HRQoL, psychological state and exercise capacity, CHSC was likely to be the optimal setting for implementing CR for patients with CHD in China.

Multiple Risk Factor Interventions for Primary Prevention of CVD in LMIC: A Cochrane Review

This study sought to determine the effectiveness of multiple risk factor interventions aimed at modifying major cardiovascular risk factors for the primary prevention of cardiovascular disease in low- and middle-income countries (LMIC). We searched electronic databases for randomized controlled trials of health promotion interventions to achieve behavior change. The pooled effect indicated a reduction in systolic blood pressure (-6.72 mm Hg; 95% confidence interval [CI]: -9.82 to -3.61; I² = 91%), diastolic blood pressure (-4.40 mm Hg; 95% CI: -6.47 to -2.34; I² = 92%), body mass index (-0.76 kg/m²; 95% CI: -1.29 to -0.22; I² = 80%), and waist circumference (-3.31 cm; 95% CI: -4.77 to -1.86; I² = 55%) in favor of multiple risk factor interventions. There is some evidence that multiple risk factor interventions may lower blood pressure levels and anthropometrics in populations in LMIC settings at high risk of hypertension and diabetes.

Evaluation of a Community Health Service Center-Based Intervention Program for Managing Chronic Heart Failure

BACKGROUND

Although the role of primary care for the management of patients with chronic heart failure (CHF) has been highly recommended, structural involvement of primary care in heart failure (HF) management programs is extremely limited.

AIMS

To examine the feasibility and applicability of two most recommended forms of care delivery mode, home visit and telephone support, for CHF management in the setting of community health service center (CHSC).

STUDY DESIGN

Prospective study.

METHODS

This study was conducted in two CHSCs in Beijing, China. Care delivery was led by trained general practitioners or community nurses via home visits in one CHSC and telephone support in the other. Data regarding the change in mortality and hospitalization rate during 12 months and self-care level at 6 months were prospectively collected and compared across the intervention groups.

RESULTS

A total of 329 patients were included, with 142 in the home visit group and 187 in the telephone support group. Patients in both groups had frequent visits to CHSC (8.1±5.9 in the home visit and 7.7±4.1 in the telephone support group, p=0.45) during the follow-up period. Compared to the telephone support group, patients in the home visit group showed a reduction in all-cause mortality (14.1% versus 20.3%, p=0.14), one or more hospitalizations due to any cause (33.8% versus 44.2%, p=0.12) and one or more hospitalizations due to cardiac cause (17.6% versus 24.6%, p=0.13) in the home visit group. The absolute differences were 6.2% (95% CI: 1.9%, 14.3%), 8.4% (95% CI: 2.1%, 18.9%) and 7.3% (95% CI: 1.5%, 16.1%), respectively, although the results were not statistically significant. After 6 months of intervention, patients in both groups achieved marked improvement in self-care with reference to their own baseline values.

CONCLUSION

Although no statistical difference was observed between the two care delivery approaches regarding the clinical outcomes of interest, given the high participation rates, the acceptable rate of adverse events, frequent CHSC visits and patients' preferences in the current study, it was concluded that CHSC might be the optimal setting for delivering care to CHF patients in China.

The Willingness-to-Pay for General Practitioners in Contractual Service and Influencing Factors among Empty Nesters in Chongqing, China

Background: In 2012, a pilot health policy of contractual service relations between general practitioners and patients was implemented in China. Due to the decline in body and cognitive function, as well as the lack of family care and narrow social support networks, the demand of health services among the elderly is much higher than that among the general population. This study aims to probe into the empty nesters’ willingness-to-pay for general practitioners using a contractual service policy, investigating empty nesters’ payment levels for the service, and analyze the main factors affecting the willingness of empty-nesters’ general practitioners using contractual service supply cost. Methods: This cross-sectional study adopted a multistage stratified sampling method to survey 865, city empty nesters (six communities in three districts of one city) aged 60–85 years. A condition value method was used to infer the distribution of the willingness-to-pay; Cox’s proportional hazards regression model was used to analyze the influencing factors of willingness-to-pay. Results: More than seventy percent (76.6%) of the empty nesters in this city were willing to pay general practitioners using contract service in Chongqing. The level of willingness-to-pay for the surveyed empty nesters was 34.1 yuan per year. The median value was 22.1 yuan per year, which was below the Chongqing urban and rural cooperative medical insurance individual funding level (60 yuan per year) in 2013. Cox’s proportional hazards regression model analysis showed that the higher the education level was, the worse the self-reported health status would be, accompanied by higher family per capita income, higher satisfaction of community health service, and higher willingness-to-pay empty nesters using a contract service. Women had a higher willingness-to-pay than men. Conclusions: The willingness-to-pay for general practitioners by contractual service is high among city empty nesters in Chongqing, thus, individual financing is feasible. However, people are willing to pay less than half of the current personal financing of cooperative medical insurance of urban and rural residents. Education level, family per capita income, and self-reported health status are the main factors affecting the cost sharing intention for general practitioners using contract service supply. According to the existing situation of different empty nesters, it is important to perfect the design of general practitioners using a contractual service policy system, according to differentiated personal financing levels.

Multiple risk factor interventions for primary prevention of cardiovascular disease in low- and middle-income countries

BACKGROUND

In many low- and middle-income countries (LMICs) morbidity and mortality associated with cardiovascular diseases (CVDs) have grown exponentially over recent years. It is estimated that about 80% of CVD deaths occur in LMICs. People in LMICs are more exposed to cardiovascular risk factors such as tobacco, and often do not have access to effective and equitable healthcare services (including early detection services). Evidence from high-income countries indicates that multiple risk factor intervention programmes do not result in reductions in CVD events. Given the increasing incidence of CVDs and lower CVD health awareness in LMICs it is possible that such programmes may have beneficial effects.

OBJECTIVES

To determine the effectiveness of multiple risk factor interventions (with or without pharmacological treatment) aimed at modifying major cardiovascular risk factors for the primary prevention of CVD in LMICs.

SEARCH METHODS

We searched (from inception to 27 June 2014) the Cochrane Library (CENTRAL, HTA, DARE, EED), MEDLINE, EMBASE, Global Health and three other databases on 27 June 2014. We also searched two clinical trial registers and conducted reference checking to identify additional studies. We applied no language limits.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of health promotion interventions to achieve behaviour change (i.e. smoking cessation, dietary advice, increasing activity levels) with or without pharmacological treatments, which aim to alter more than one cardiovascular risk factor (i.e. diet, reduce blood pressure, smoking, total blood cholesterol or increase physical activity) of at least six months duration of follow-up conducted in LMICs.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial eligibility and risk of bias, and extracted data. We combined dichotomous data using risk ratios (RRs) and continuous data using mean differences (MDs), and presented all results with a 95% confidence interval (CI). The primary outcome was combined fatal and non-fatal cardiovascular disease events.

MAIN RESULTS

Thirteen trials met the inclusion criteria and are included in the review. All studies had at least one domain with unclear risk of bias. Some studies were at high risk of bias for random sequence generation (two trials), allocation concealment (two trials), blinding of outcome assessors (one trial) and incomplete outcome data (one trial). Duration and content of multiple risk factor interventions varied across the trials. Two trials recruited healthy participants and the other 11 trials recruited people with varying risks of CVD, such as participants with known hypertension and type 2 diabetes. Only one study reported CVD outcomes and multiple risk factor interventions did not reduce the incidence of cardiovascular events (RR 0.57, 95% CI 0.11 to 3.07, 232 participants, low-quality evidence); the result is imprecise (a wide confidence interval and small sample size) and makes it difficult to draw a reliable conclusion. None of the included trials reported all-cause mortality. The pooled effect indicated a reduction in systolic blood pressure (MD -6.72 mmHg, 95% CI -9.82 to -3.61, I² = 91%, 4868 participants, low-quality evidence), diastolic blood pressure (MD -4.40 mmHg, 95% CI -6.47 to -2.34, I² = 92%, 4701 participants, low-quality evidence), body mass index (MD -0.76 kg/m², 95% CI -1.29 to -0.22, I² = 80%, 2984 participants, low-quality evidence) and waist circumference (MD -3.31, 95% CI -4.77 to -1.86, I² = 55%, 393 participants, moderate-quality evidence) in favour of multiple risk factor interventions, but there was substantial heterogeneity. There was insufficient evidence to determine the effect of these interventions on consumption of fruit or vegetables, smoking cessation, glycated haemoglobin, fasting blood sugar, high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol and total cholesterol. None of the included trials reported on adverse events.

AUTHORS' CONCLUSIONS

Due to the limited evidence currently available, we can draw no conclusions as to the effectiveness of multiple risk factor interventions on combined CVD events and mortality. There is some evidence that multiple risk factor interventions may lower blood pressure levels, body mass index and waist circumference in populations in LMIC settings at high risk of hypertension and diabetes. There was considerable heterogeneity between the trials, the trials were small, and at some risk of bias. Larger studies with longer follow-up periods are required to confirm whether multiple risk factor interventions lead to reduced CVD events and mortality in LMIC settings.
