Background Digital health interventions ( DHI ) have been shown to improve intermediates of cardiovascular health , but their impact on cardiovascular ( CV ) outcomes has not been fully explored . The aim of this study was to determine whether DHI administered during cardiac rehabilitation ( CR ) would reduce CV‐related emergency department ( ED ) visits and rehospitalizations in patients after percutaneous coronary intervention ( PCI ) for acute coronary syndrome ( ACS ) . Methods We r and omized patients undergoing CR following ACS and PCI to st and ard CR ( n = 40 ) or CR + DHI ( n = 40 ) for 3 months with 3 patients withdrawing from CR prior to initiation in the treatment arm and 6 in the control group . The DHI incorporated an online and smartphone‐based CR platform asking the patients to report of dietary and exercise habits throughout CR as well as educational information toward patients ' healthy lifestyles . We obtained data regarding ED visits and rehospitalizations at 180 days , as well as other metrics of secondary CV prevention at baseline and 90 days . Results Baseline demographics were similar between the groups . The DHI + CR group had improved weight loss compared to the control group ( −5.1 ± 6.5 kg vs. −0.8 ± 3.8 kg , respectively , P = .02 ) . Those in the DHI + CR group also showed a non‐significant reduction in CV‐related rehospitalizations plus ED visits compared to the control group at 180 days ( 8.1 % vs 26.6 % ; RR 0.30 , 95 % CI 0.08‐1.10 , P = .054 ) . Conclusions The current study demonstrated that complementary DHI  significantly improves weight loss , and might offer a method to reduce CV‐related ED visits plus rehospitalizations in patients after ACS undergoing CR . The study suggests a role for DHI as an adjunct to CR to improve secondary prevention of CV disease . Trial registration This trial is registered at clinical trials.gov ( NCT01883050 ) BACKGROUND Primary prevention of cardiovascular disease (CVD),by identifying individuals at risk is a well-established , but costly strategy when based on measurements that depend on laboratory analyses . A non-laboratory , paper-based CVD risk assessment chart tool has previously been developed to make screening more affordable in developing countries . Task shifting to community health workers ( CHWs ) is being investigated to further scale CVD risk screening . This study aim ed to develop a mobile phone CVD risk assessment application and to evaluate its impact on CHW training and the duration of screening for CVD in the community by CHWs . METHODS A feature phone application was developed using the open source online platform , CommCare ( © ) . CHWs ( n=24 ) were trained to use both paper-based and mobile phone CVD risk assessment tools . They were r and omly allocated to using one of the risk tools to screen 10 - 20 community members and then crossed over to screen the same number , using the alternate risk tool . The impact on CHW training time , screening time and margin of error in calculating risk scores was recorded . A focus group discussion evaluated experiences of CHWs using the two tools . RESULTS The training time was 12.3h for the paper-based chart tool and 3h for the mobile phone application . 537 people were screened . The mean screening time was 36 min ( SD=12.6 ) using the paper-base chart tool and 21 min ( SD=8.71 ) using the mobile phone application , p=<0.0001 . Incorrect calculations ( 4.3 % of average systolic BP measurements , 10.4 % of BMI and 3.8 % of CVD risk score ) were found when using the paper-based chart tool while all the mobile phone calculations were correct . Qualitative findings from the focus group discussion corresponded with the findings of the pilot study . CONCLUSION The reduction in CHW training time , CVD risk screening time , lack of errors in calculation of a CVD risk score and end user satisfaction when using a mobile phone application , has implication s in terms of adoption and sustainability of this primary prevention strategy to identify people with high CVD risk who can be referred for appropriate diagnoses and treatment OBJECTIVE The Diabetes Care Protocol ( DCP ) , a multifaceted computerized decision support diabetes management intervention , reduces cardiovascular risk of type 2 diabetic patients . We performed a cost-effectiveness analysis of DCP from a Dutch health care perspective . RESEARCH DESIGN AND METHODS A cluster r and omized trial provided data of DCP versus usual care . The 1-year follow-up patient data were extrapolated using a modified Dutch microsimulation diabetes model , computing individual lifetime health-related costs , and health effects . Incremental costs and effectiveness ( quality -adjusted life-years [ QALYs ] ) were estimated using multivariate generalized estimating equations to correct for practice -level clustering and confounding . Incremental cost-effectiveness ratios ( ICERs ) were calculated and cost-effectiveness acceptability curves were created . Stroke costs were calculated separately . Subgroup analyses examined patients with and without cardiovascular disease ( CVD+ or CVD− patients , respectively ) . RESULTS Excluding stroke  , DCP patients lived longer ( 0.14 life-years , P = NS ) , experienced more QALYs ( 0.037 , P = NS ) , and incurred higher total costs ( € 1,415 , P = NS ) , result ing in an ICER of € 38,243 per QALY gained . The likelihood of cost-effectiveness given a willingness-to-pay threshold of € 20,000 per QALY gained is 30 % . DCP had a more favorable effect on CVD+ patients ( ICER = € 14,814 ) than for CVD− patients ( ICER = € 121,285 ) . Coronary heart disease costs were reduced ( € −587 , P < 0.05 ) . CONCLUSIONS DCP  reduces cardiovascular risk , result ing in only a slight improvement in QALYs , lower CVD costs , but higher total costs , with a high cost-effectiveness ratio . Cost-effective care can be achieved by focusing on cardiovascular risk factors in type 2 diabetic patients with a history of CVD We used outcome data from a r and omized work site intervention trial to examine the cost-effectiveness of four cardiovascular disease ( CVD ) risk reduction programs : health risk assessment ( HRA ) , risk factor education ( RFE ) , behavioral counseling ( BC ) , and behavioral counseling plus incentives ( BCI ) . Composite CVD risk scores were derived from measures of serum total cholesterol , blood pressure , number of cigarettes smoked , body mass index , and aerobic capacity . The economic evaluation of the programs focused on the subset of costs most sensitive to the differences between the interventions , and a sensitivity analysis examined some of the relevant cost variations . At the 6-month follow-up ( i.e. , the " action " or initiation stage of lifestyle change ) , the RFE , BC , and BCI interventions produced a significant reduction in cardiovascular risk . Incremental analyses demonstrated RFE to be more cost-effective , but not as clinical ly effective as BC ; BC was more cost-effective than RFE when assessment costs were included , and BCI was judged to be the least cost-effective . At the 12-month follow-up ( i.e. , the " maintenance " stage of lifestyle of change ) , BC was the only program found to produce a significant reduction in CVD risk .  Individualized behavioral counseling was found to be a cost-effective strategy for the initiation and maintenance of CVD risk factor reduction Introduction While a number of strategies are being implemented to control cardiovascular diseases ( CVDs ) and type 2 diabetes mellitus ( T2DM ) , the cost-effectiveness of these in the South Asian context has not been systematic ally evaluated . We aim to systematic ally review the economic ( cost-effectiveness ) evidence available on the individual- , group- and population -level interventions for control of CVD and T2DM in South Asia . Methods and analysis This review will consider all relevant economic evaluations , either conducted alongside r and omised controlled trials or based on decision modelling estimates . These studies must include participants at risk of developing CVD/T2DM or with established disease in one or more of the South Asian countries ( India , Bangladesh , Pakistan , Sri Lanka , Nepal , Maldives , Bhutan and Afghanistan ) . We will identify relevant papers by systematic ally search ing all major data bases and registries . Selected articles will be screened by two independent research ers . Method ological quality of the studies will be assessed using a modified Drummond and a Phillips checklist . Cochrane guidelines will be followed for bias assessment in the effectiveness studies . Results Results will be presented in line with the PRISMA ( Preferred Reporting Items for Systematic review and Meta- analysis ) checklist , and overall quality of evidence will be presented as per the GRADE ( Grade s of Recommendation , Assessment , Development and Evaluation ) approach . Ethics and dissemination The study has received ethics approval from the All India Institute of Medical Sciences , New Delhi , India . The results of this review will provide policy-relevant recommendations for the uptake of cost-effectiveness evidence in prioritising decisions on essential chronic disease care packages for South Asia . Study registration number PROSPERO CRD42013006479 Objectives To investigate the long-term cost-effectiveness ( measured as the ratio of incremental NHS cost to incremental quality -adjusted life years ) of a telehealth intervention for patients with raised cardiovascular disease ( CVD ) risk . Design A cohort simulation model developed as part of the economic evaluation conducted alongside the Healthlines r and omised controlled trial . Setting Patients recruited through primary care , and intervention delivered via telehealth service .  Participants Participants with a 10-year CVD risk ≥20 % , as measured by the QRISK2 algorithm , and with at least 1 modifiable risk factor , individually r and omised from 42 general practice s in Engl and . Intervention A telehealth service delivered over a 12-month period . The intervention involved a series of responsive , theory-led encounters between patients and trained health information advisors who provided access to information re sources and supported medication adherence and coordination of care . Primary and secondary outcome measures Cost-effectiveness measured by net monetary benefit over the simulated lifetime of trial participants from a UK National Health Service perspective . Results The probability that the intervention was cost-effective depended on the duration of the effect of the intervention . The intervention was cost-effective with high probability if effects persisted over the lifetime of intervention recipients . The probability of cost-effectiveness was lower for shorter duration s of effect . Conclusions The intervention was likely to be cost-effective under a lifetime perspective . Trial registration number IS RCT N27508731 ; Results Background Large gaps exist in the implementation of guideline recommendations for cardiovascular disease ( CVD ) risk management .  Electronic decision support ( EDS ) systems are promising interventions to close these gaps but few have undergone clinical trial evaluation in Australia . We have developed HealthTracker , a multifaceted EDS and quality improvement intervention to improve the management of CVD risk . Methods / design It is hypothesised that the use of HealthTracker over a 12-month period will result in : ( 1 ) an increased proportion of patients receiving guideline -indicated measurements of CVD risk factors and ( 2 ) an increased proportion of patients at high risk will receive guideline -indicated prescriptions for lowering their CVD risk . Sixty health services ( 40 general practice s and 20 Aboriginal Community Controlled Health Services ( ACCHSs ) will be r and omised in a 1:1 allocation to receive either the intervention package or continue with usual care , stratified by service type , size and participation in existing quality improvement initiatives . The intervention consists of point-of-care decision support ; a risk communication interface ; a clinical audit tool to assess performance on CVD-related indicators ; a quality improvement component comprising peer-ranked data feedback and support to develop strategies to improve performance .  The control arm will continue with usual care without access to these intervention components . Quantitative data will be derived from cross-sectional sample s at baseline and end of study via automated data extraction . Detailed process and economic evaluations will also be conducted . Ethics and dissemination The general practice component of the study is approved by the University of Sydney Human Research Ethics Committee ( HREC ) and the ACCHS component is approved by the Aboriginal Health and Medical Research Council HREC . Formal agreements with each of the participating sites have been signed . In addition to the usual scientific forums , results will be disseminated via newsletters , study websites , face-to-face feedback forums and workshops . Trial registration The trial is registered with the Australian Clinical Trials Registry ACTRN 12611000478910 BACKGROUND To evaluate the long-term cost-effectiveness of two home-based cardiac rehabilitation ( CR ) interventions ( Healthy Weight ( HW ) and Physical Activity ( PA ) ) for patients with cardiovascular disease ( CVD ) , who had been referred to cardiac rehabilitation ( CR ) but had not attended . The interventions consisted of pedometer-based telephone coaching sessions on weight , nutrition and physical activity ( HW group ) or physical activity only ( PA group ) and were compared to a control group who received information brochures about physical activity . METHODS A cost-effectiveness analysis was conducted using data from two r and omised controlled trials . One trial compared HW to PA ( PANACHE study ) , and the second compared PA to usual care . A Markov model was developed which used one risk factor , body mass index ( BMI ) to determine the CVD risk level and mortality . Patient-level data from the trials were used to determine the transitions to CVD states and healthcare related costs . The model was run for separate cohorts of males and females . Univariate and probabilistic sensitivity analysis were conducted to test the robustness of the results . RESULTS Given a willingness-to-pay threshold of $ 50,000/QALY , in the long run , both the HW and PA interventions are cost-effective compared with usual care . While the HW intervention is more effective , it also costs more than both the PA intervention and the control group due to higher intervention costs . However , the HW intervention is still cost-effective relative to the PA intervention for both men and women . Sensitivity analysis suggests that the results are robust . CONCLUSION The results of this paper provide evidence of the long-term cost-effectiveness of home-based CR interventions for patients who are referred to CR but do not attend . Both the HW and PA interventions can be recommended as cost-effective home-based CR programs , especially for people lacking access to hospital services or who are unable to participate in traditional CR programs BACKGROUND Computerized decision support systems ( CDSSs ) are believed to enhance patient care and reduce healthcare costs ; however the current evidence is limited and the cost-effectiveness remains unknown . OBJECTIVE To estimate the long-term cost-effectiveness of a CDSS linked to evidence -based treatment recommendations for type 2 diabetes . METHODS Using the Ontario Diabetes Economic Model , changes in factors ( eg , HbA1c ) from a r and omized controlled trial were used to estimate cost-effectiveness . The cost of implementation , development , and maintenance of the core data set , and projected diabetes-related complications were included . The base case assumed a 1-year treatment effect , 5 % discount rate , and 40-year time horizon . Univariate , one-way sensitivity analyses were carried out by altering different parameter values . The perspective was the Ontario Ministry of Health and costs were in 2010 Canadian dollars . RESULTS The cost of implementing the intervention was $ 483,699 . The one-year intervention reduced HbA1c by 0.2 and systolic blood pressure by 3.95 mm Hg , but increased body mass index by 0.02 kg/m² , result ing in a relative risk reduction of 14 % in the occurrence of amputation . The model estimated that the intervention result ed in an additional 0.0117 quality -adjusted life year ; the incremental cost-effectiveness ratio was $ 160,845 per quality -adjusted life-year . CONCLUSION The web-based prototype decision support system slightly improved short-term risk factors . The model predicted moderate improvements in long-term health outcomes . This disease management program will need to develop considerable efficiencies in terms of costs and processes or improved effectiveness to be considered a cost-effective intervention for treating patients with type 2 diabetes BACKGROUND Diabetes is a chronic disease , with high prevalence across many nations , which is characterized by elevated level of blood glucose and risk of acute and chronic complication . The Kingdom of Saudi Arabia ( KSA ) has one of the highest levels of diabetes prevalence globally . It is well-known that the treatment of diabetes is complex process and requires both lifestyle change and clear pharmacologic treatment plan . To avoid the complication from diabetes , the effective behavioural change and extensive education and self-management is one of the key approaches to alleviate such complications . However , this process is lengthy and expensive . The recent studies on the user of smart phone technologies for diabetes self-management have proven to be an effective tool in controlling hemoglobin ( HbA1c ) levels especially in type-2 diabetic ( T2D ) patients . However , to date no reported study addressed the effectiveness of this approach in the in Saudi patients . This study investigates the impact of using mobile health technologies for the self-management of diabetes in Saudi Arabia . METHODS In this study , an intelligent mobile diabetes management system ( SAED ) , tailored for T2D patients in KSA was developed . A pilot study of the SAED system was conducted in Saudi Arabia with 20 diabetic patients for 6 months duration . The patients were r and omly categorized into a control group who did not use the SAED system and an intervention group whom used the SAED system for their diabetes management during this period . At the end of the follow-up period , the HbA1c levels in the patients in both groups were measure together with a diabetes knowledge test was also conducted to test the diabetes awareness of the patients . RESULTS The results of SAED pilot study showed that the patients in the intervention group were able to significantly decrease their HbA1c levels compared to the control group . The SAED system also enhanced the diabetes awareness amongst the patients in the intervention group during the trial period . These outcomes confirm the global studies on the effectiveness of smart phone technologies in diabetes management . The significance of the study is that this was one of the first such studies conducted on Saudi patients and of their acceptance for such technology in their diabetes self-management treatment plans . CONCLUSIONS The pilot study of the SAED system showed that a mobile health technology can significantly improve the HbA1C levels among Saudi diabetic and improve their disease management plans . The SAED system can also be an effective and low-cost solution in improving the quality of life of diabetic patients in the Kingdom considering the high level of prevalence and the increasing economic burden of this disease AIMS Cardiovascular disease ( CVD ) is the leading cause of morbidity and mortality in people with diabetes in South Asia . The CARRS Translation Trial tests the effectiveness , cost-effectiveness , and sustainability of a clinic-based multi-component CVD risk reduction intervention among people with diabetes in India and Pakistan . METHODS We r and omly assigned 1146 adults with diabetes recruited from 10 urban clinic sites , to receive usual care by physicians or to receive an integrated multi-component CVD risk reduction intervention . The intervention involves electronic health record management , decision-support prompts to the healthcare team , and the support of a care coordinator to actively facilitate patient and provider adherence to evidence -based guidelines . The primary outcome is a composite of multiple CVD risk factor control ( blood glucose and either blood pressure or cholesterol , or all three ) . Other outcomes include control of the individual CVD risk factors , process and patient-centered measures , cost-effectiveness , and acceptability/feasibility . CONCLUSION The CARRS Translation Trial tests a low-cost diabetes care delivery model in urban South Asia to achieve comprehensive cardio-metabolic disease case-management of high-risk patients ( clinical trials.gov number : NCT01212328 ) AIMS The rapidly increasing prevalence of chronic diseases is an important challenge to healthcare systems worldwide . To improve the quality and efficiency of chronic disease care , we investigated the effectiveness and applicability of the Ubiquitous Chronic Disease Care ( UCDC ) system using cellular phones and the internet for overweight patients with both Type 2 diabetes and hypertension . METHODS We conducted a r and omized , controlled clinical trial over 3 months that included 123 patients at a university hospital and a community public health centre . RESULTS After 12 weeks , there were significant improvements in HbA(1c ) in the intervention group ( 7.6 + /- 0.9 % to 7.1 + /- 0.8 % , P < 0.001 ) compared with the control group ( 7.4 + /- 0.9 % to 7.6 + /- 1.0 % , P = 0.03 ) . Furthermore , we observed a significant reduction in systolic and diastolic blood pressure , as well as improvements in total cholesterol , low-density lipoprotein-cholesterol and triglyceride levels in the intervention group . Furthermore , there was a significant increase in adiponectin levels in the intervention group compared with the control group , although high-sensitivity C-reactive protein and interleukin-6 levels did not change in either group . CONCLUSIONS The novel UCDC system presented in this paper improved multiple metabolic parameters simultaneously in overweight patients with both Type 2 diabetes and hypertension Mainstream preventive interventions often fail to reach poor population s with a high risk of cardiovascular diseases ( CVDs ) in Pakistan . A community-based CVD primary prevention project aim ed at developing approaches to reduce risk factors in such population s was established by Heartfile in collaboration with the National Rural Support Program in the district of Lodhran . The project implemented a range of activities integrated with existing social and health service mechanisms during a three year intervention period 2000/01 - 03/04 . These were targeted in 4 key setting s : community health education , mass media interventions , training of health professionals and health education through Lady Health Workers . The project received support from the Department for International Development , UK . At the community level , a pre-test-post-test quasi-experimental design was used for examining project outcomes related to the community component of the intervention . Pre and post-intervention ( training ) evaluations were conducted involving all health care providers in r and omly selected workshops in order to determine baseline levels of knowledge and the impact of training on knowledge level . In order to assess practice s of physician and non-physician health care providers patient interviews , with control comparisons were conducted at each health care facility . Significant positive changes were observed in knowledge levels at a community level in the district of intervention compared with baseline knowledge levels particularly in relation to a heart healthy diet , beneficial level of physical activity , the causes of high blood pressure and heart attack and the effects of high blood pressure and active and passive smoking on health . Significant changes in behaviors at a practice level were not shown in the district of intervention . However the project played a critical role in spurring national action for the prevention and control of non-communicable diseases and introducing sustainable public health interventions for poor communities in Pakistan Background Cardiovascular disease ( CVD ) is the leading cause of death worldwide . Cardiac rehabilitation ( CR ) is aim ed at improving health behaviors to slow or reverse the progression of CVD disease . Exercise is a central element of CR . Technologies such as mobile phones and the Internet ( mHealth ) offer potential to overcome many of the psychological , physical , and geographical barriers that have been associated with lack of participation in exercise-based CR . We aim to trial the effectiveness of a mobile phone delivered exercise-based CR program to increase exercise capacity and functional outcomes compared with usual CR care in adults with CVD . This paper outlines the rationale and methods of the trial . Methods A single-blinded parallel two-arm r and omized controlled trial is being conducted . A total of 170 people will be r and omized at 1:1 ratio either to receive a  mHealth CR program  or usual care .  Participants are identified by CR nurses from two metropolitan hospitals in Auckl and , New Zeal and through outpatient clinics and existing data bases . Consenting participants are contacted to attend a baseline assessment . The intervention consists of a theory-based , personalized , automated package of text and video message components via participants ' mobile phones and the Internet to increase exercise behavior , delivered over six months . The control group will continue with usual CR . Data collection occurs at baseline and 24 weeks ( post-intervention ) . The primary outcome is change in maximal oxygen uptake from baseline to 24 weeks . Secondary outcomes include post-intervention measures on self-reported physical activity ( IPAQ ) , cardiovascular risk factors ( systolic blood pressure , weight , and waist to hip ratio ) , health related quality of life ( SF-36 ) , and cost-effectiveness . Discussion This manuscript presents the protocol for a r and omized controlled trial of a mHealth exercise-based CR program . Results of this trial will provide much needed information about physical and psychological well-being , and cost-effectiveness of an automated telecommunication intervention . If effective , this intervention has enormous potential to improve the delivery of CR and could easily be scaled up to be delivered nationally ( and internationally ) in a very short time , enhancing the translational aspect of this research . It also has potential to extend to comprehensive CR ( nutrition advice , smoking cessation , medication adherence).Trial Registration Background Very few studies having decision support systems as an intervention report on patient outcomes for cardiovascular disease in the Western world . The potential role of decision support system for the management of blood pressure among Indian hypertensives remains unclear . We propose a cluster r and omised trial that aims to test the effectiveness and cost effectiveness of DSS among Indian hypertensive patients . Methods The trial design is a cluster r and omised community intervention trial , in which the participants would be adult male and female hypertensive patients , in the age group of 35 to 64 years , reporting to the Primary Health Care centres of Mahabubnagar district , And hra Pradesh , India . The objective of the study is to test the effectiveness and compare the cost effectiveness and cost utility among hypertensive subjects r and omized to receive either decision support system or a chart based algorithmic support system in urban and rural areas of a district in the state of And hra Pradesh , India ( baseline versus 12 months follow up ) . The primary outcome would be a comparison of the systolic blood pressure at 0 and 12 months among hypertensive patients r and omized to receive the decision support system or the chart based algorithmic support system . Computer generated r and omisation and an investigator and analyser blinded method would be followed . 1600 participants ; 800 to each arm ; each arm having eight clusters of hundred participants each have been recruited between 01 August 2011 - 01 March 2012 . A twelve month follow up will be completed by March 2013 and results are expected by April 2013 . Discussion This cluster r and omized community intervention trial on DSS will enable policy makers to find out the effectiveness , cost effectiveness and cost utility of decision support system for management of blood pressure among hypertensive patients in India . Most of the previous studies on decision support system have focused on physician performance , adherence and on preventive care reminders . The uniqueness of the proposed study lies in finding out the effectiveness of a decision support system on patient related outcomes .Trial registration CTRI/2012/03/002476 , Clinical Trial Registry - India Introduction : A large proportion of the cardiovascular disease ( CVD ) burden can potentially be prevented by primary prevention programs addressing major causal risk factors . A Web-based health risk assessment ( HRA ) with tailored feedback for individual health promotion is a promising strategy . We evaluated the effect on CVD risk of such a program among employees of a Dutch worksite . Methods : We conducted a prospect i ve follow-up study among 368 employees who voluntarily participated in a Web-based HRA program at a single Dutch worksite in 2008 . The program included a multicomponent HRA through a Web-based electronic question naire , biometrics , and laboratory evaluation . The results were combined with health behavior change theory to generate tailored motivational and educational health advice . On request , a health counseling session with the program physician was available . Follow-up data on CVD risk were collected 1 year after initial participation . The primary outcome was a change in Framingham CVD risk at 6 months relative to baseline . We checked for a possible background effect of an increased health consciousness as a consequence of program introduction at the worksite by comparing baseline measurements of early program participants with baseline measurements of participants who completed the program 6 months later . Results : A total of 176 employees completed follow-up measurements after a mean of 7 months . There was a grade d relation between CVD risk changes and baseline risk , with a relative reduction of 17.9 % ( P = 0.001 ) in the high-risk category ( baseline CVD risk ≥20 % ) . Changes were not explained by additional health counseling , medication , or an increase in health consciousness within the company . Conclusions : Voluntary participation in a Web-based HRA with tailored feedback at the worksite reduced CVD risk by nearly 18 % among participants at high CVD risk and by nearly 5 % among all participants . Web-based HRA could improve CVD risk in similar population s. Future research should focus on the persistence of the effects underlying the CVD risk reduction Background Mobile phone technologies including SMS ( short message service ) have been used to improve the delivery of health services in many countries . However , data on the effects of mobile health technology on patient outcomes in re source -limited setting s are limited . The aim of this study therefore is to measure the impact of a mobile phone SMS service  on treatment success of newly diagnosed type 2 diabetes in an urban area of Bangladesh . Methods / design This is a single-centred r and omized controlled intervention trial ( prospect i ve ) comparing st and ard-of-care with st and ard-of-care plus a mobile phone-based SMS intervention for 6 months . A total of 216 participants with newly diagnosed type 2 diabetes will be recruited . Data will be collected at the outpatient department of Bangladesh Institute of Health Science ( BIHS ) hospital at baseline and after 6 months . The primary outcome measure will be change in HbA1c between baseline and 6 months . The secondary outcome measures are self-reported medication adherence , clinic attendance , self-reported adoption of healthy behaviours , diabetes knowledge , quality of life and cost effectiveness of the SMS intervention .  The inclusion criteria will be as follows : diagnosed as patients with type 2 diabetes by the BIHS physician , using oral medication therapy , living in Dhaka city , registered with the BIHS hospital , using a mobile phone , willing to return for follow up after 6 months and providing written informed consent . Participants will be allocated to control and intervention arms after recruitment using a r and omization software . Data will be collected on socio-demographic and economic information , mobile phone use and habits , knowledge of prevention , management and complications of diabetes , self-perceived quality of life assessment , self-reported diseases , medical history , family history of diseases , medication history , medication adherence , health seeking behaviour , tobacco use , physical activity , diet , mental health status , life events and disability , anthropometric measurements of weight , height , blood pressure and blood tests for HbA1c . Discussion Mobile phone SMS services have the potential to communicate with diabetes patients and to build awareness about the disease , improve self-management and avoid complications also in re source -limited setting . If this intervention proves to be efficient and cost-effective in the current trial , large-scale implementation could be undertaken . Trial registration DRKS00005188
This study is the first systematic review of decision analytic model-based cost-effectiveness analyses of DHIs in the management of CVDs .
All the included studies found the DHIs to be cost-effective
BACKGROUND With the advancement in information technology and mobile internet , digital health interventions ( DHIs ) are improving the care of cardiovascular diseases ( CVDs ) .
The impact of DHIs on cost-effective management of CVDs has been examined using the decision analytic model-based health technology assessment approach .
OBJECTIVE The aim of this study was to perform a systematic review of the decision analytic model-based studies evaluating the cost-effectiveness of DHIs on the management of CVDs .
