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 Clinical decision support systems ( CDSSs ) differ from other health information systems in their aim to directly influence the decision-making behaviour of healthcare professionals . As a result , CDSSs face additional challenges with respect to user acceptance . The objective of this study was to investigate subjective usability of a guideline -based CDSS for outpatient cardiac rehabilitation . The system , named CARDSS , was previously found to be effective in improving guideline adherence of rehabilitation professionals in a cluster r and omized trial . To assess  CARDSS ' usability , a modified version of the IBM Computer System Usability Question naire was sent to all 68 professionals from the 28 outpatient clinics that participated in the trial . The question naire was returned by 63 respondents ( 93 % ) from 27 clinics . Factors that influenced  CARDSS ' usability were identified using linear regression analysis . Analysis showed that professionals who managed to smoothly integrate the system with their daily routine were more satisfied with ease of system use . Furthermore , a positive attitude of respondents towards CDSSs in general and a better agreement with the content of the national guidelines were positively correlated to satisfaction with CARDSS ' overall usability and each of its sub-domains OBJECTIVE Computer-based clinical decision support systems ( CDSSs ) vary greatly in design and function . Using a taxonomy that we had previously developed , we describe the characteristics of CDSSs reported in the literature . METHODS We search ed PubMed and the Cochrane Library for r and omized controlled trials ( RCTs ) published in English between 1998 and 2003 that evaluated CDSSs .  We coded each CDSS using our taxonomy . RESULTS 58 studies met our inclusion criteria . The 74 reported CDSSs varied greatly in context of use , knowledge and data sources , nature of decision support offered , information delivery , and workflow impact . Two distinct subsets of CDSSs were seen : patient-directed systems that provided decision support for preventive care or health-related behaviors via mail or phone ( 38 % of systems ) , and inpatient systems targeting clinicians with online decision support and direct online execution of the recommendations ( 18 % ) . 84 % of the CDSSs required extra staffing for h and ling CDSS-related input or output . CONCLUSION Reported CDSSs are heterogeneous along many dimensions . Caution should be taken in generalizing the results of CDSS RCTs to different clinical or workflow setting BACKGROUND Computerized decision support systems ( CDSSs ) linked with electronic medical records ( EMRs ) are promoted as an effective means of improving patient care . However , very few high- quality studies are set in routine , community-based clinical care , and no consistent evidence of an effect on patient outcomes has been found . METHODS A r and omized controlled trial among EMR-using primary care practice s in Ontario , Canada . Patients 55 years or older with previous vascular events , diabetes mellitus , hypertension , or hypercholesterolemia were r and omized to the Computerization of Medical Practice s for the Enhancement of Therapeutic Effectiveness ( COMPETE III ) CDSS intervention or to usual care . The intervention included personally tailored electronic vascular risk monitoring and treatment advice shared between the physician and patient , risk calculation , and a clinical re source . The primary outcome was a composite score of 8 recommended process outcomes at 1 year . Data collectors were blinded to group allocation . Analysis used the intention-to-treat principle with multiple imputation for missing data . RESULTS We r and omized and included in the analysis 1102 patients in 49 community-based physician practice s ( 53.4 % female ; mean age , 69.1 years ; 28.0 % with a previous vascular event ) . The intervention group ( 545 [ 49.5 % ] ) had a significantly greater improvement in mean process composite , with a difference of 4.70 ( P < .001 ) on a 27-point scale . Intervention patients had significantly higher odds of rating their continuity of care ( 4.18 ; P < .001 ) and their ability to improve their vascular health ( 3.07 ; P < .001 ) as improved . Despite this improvement , the clinical outcomes -vascular events , clinical variables , and quality of life-were not improved . CONCLUSION Despite favorable review s and important improvements in the complex processes required to reduce vascular risk , clinical outcomes remain unchanged Background The gap between the level of care recommended by evidence -based clinical practice guidelines and the actual care delivered to patients in practice has been well established . The Canadian Diabetes Association ( CDA ) created an implementation strategy to improve the implementation of its 2008 guidelines . This study will evaluate the impact of the strategy to improve cardiovascular disease ( CVD ) screening , prevention and treatment for people with diabetes . Design A pragmatic cluster-r and omized trial will be conducted to evaluate the CDA 's CVD Toolkit .  All family physicians in Ontario , Canada were r and omly allocated to receive the Toolkit , which includes several printed educational material s targeting CVD screening , prevention and treatment , either in spring 2009 ( intervention arm ) or in spring 2010 ( control arm ) . R and omization occurred at the level of the practice . Forty family physicians from each arm will be recruited to participate , and the medical records for 20 of their diabetic patients at high risk for CVD will be retrospectively review ed . Outcome measures will be assessed for each patient between July 2009 and March 2010 . The primary outcome will be that the patient is receiving a statin .  Secondary outcomes will include 1 ) the receipt of an angiotensin converting enzyme inhibitor or angiotensin receptor blocker , 2 ) various intermediate measures ( A1c , blood pressure , LDL-cholesterol , total-/HDL-cholesterol ratio , body mass index and waist circumference ) , and 3 ) clinical inertia ( the failure to change therapy in response to an abnormal A1c , blood pressure or cholesterol reading ) . The analysis will be carried out using multilevel hierarchical logistic regression models to account for the clustered nature of the data . The group assignment will be a physician-level variable . In addition , a process evaluation study with six focus groups of family physicians will assess the acceptability of the CDA 's Toolkit and will explore factors contributing to any change or lack of change in behaviour , from the perspectives of family physicians . Discussion Printed educational material s for physicians have been shown to exert small-to-moderate changes in patient care . The CDA 's CVD Toolkit is an example of a practice guideline implementation strategy that can be disseminated to a wide audience relatively inexpensively , and so demonstrating its effectiveness at improving diabetes care could have important consequences for guideline developers , policy makers and clinicians . Trial Registration The trial is registered with http://www . clinical trials.gov , ID # Background Cardiovascular disease ( CVD ) is a major cause of death in China . Despite government efforts , the majority of hypertensive and diabetic patients in China do not receive proper treatment . Reducing CVD events requires long-term care that is proactive , patient-centred , community-based , and sustainable . We have design ed a package of interventions for patients at high risk of CVD to be implemented by family doctors based in township hospitals ( providers of primary care ) in rural Zhejiang , China . This trial aims to determine whether the systematic CVD risk reduction package results in reduced CVD events among patients at risk of CVD compared with usual care , and whether the package is cost-effective and suitable for routine implementation and scale-up . Methods / Design This is a prospect i ve , open-label , cluster r and omized controlled trial ( RCT ) with blinded data analysis . The trial will r and omize 67 township hospitals with 31,708 participants in three counties in Zhejiang Province . Participants will be identified from existing health records and will comprise adults aged 50 to 74 years , with a calculated 10-year CVD risk of 20 % or higher , or diabetes . In the intervention arm , participants will receive a package of interventions including : 1 ) healthy lifestyle counseling ( smoking cessation , and salt , oil , and alcohol reduction ) ; 2 ) prescription of a combination of drugs ( antihypertensives , aspirin , and statin ) ; and 3 ) adherence support for drug compliance and healthy lifestyle change . In the control arm , participants will receive usual care for hypertension and diabetes management at individual clinicians ’ discretion . The primary outcome is the incidence of severe CVD events over 24 months of follow-up . All CVD events will be defined according to the World Health Organization ( WHO ) monitoring of trends and determinants in cardiovascular disease ( MONICA ) definitions , diagnosed at the county hospital or higher level , and reported by the Zhejiang surveillance system . Secondary outcomes include : mean systolic and diastolic blood pressure , blood glucose , serum total cholesterol ( TC ) , and adherence to appointments , and drugs and lifestyle changes . Discussion This trial focuses on risk reduction of CVD rather than specific diseases . It is not design ed to compare therapeutic and healthy lifestyle interventions , but rather their combined effects in primary care setting s. Through the trial , we intend to underst and the effectiveness of the comprehensive CVD reduction package in routine practice . We also intend to underst and the barriers and facilitators to implementing the package , and thus to advise on policy and practice change . Trial registration Current Controlled Trials : IS RCT BACKGROUND Exposure to combination antiretroviral therapy ( cART ) can lead to important metabolic changes and increased risk of coronary heart disease ( CHD ) . Computerized clinical decision support systems have been advocated to improve the management of patients at risk for CHD but it is unclear whether such systems reduce patients ' risk for CHD . METHODS We conducted a cluster trial within the Swiss HIV Cohort Study ( SHCS ) of HIV-infected patients , aged 18 years or older , not pregnant and receiving cART for > 3 months . We r and omized 165 physicians to either guidelines for CHD risk factor management alone or guidelines plus CHD risk profiles . Risk profiles included the Framingham risk score , CHD drug prescriptions and CHD events based on biannual assessment s , and were continuously up date d by the SHCS data centre and integrated into patient charts by study nurses . Outcome measures were total cholesterol , systolic and diastolic blood pressure and Framingham risk score . RESULTS A total of 3,266 patients ( 80 % of those eligible ) had a final assessment of the primary outcome at least 12 months after the start of the trial . Mean ( 95 % confidence interval ) patient differences where physicians received CHD risk profiles and guidelines , rather than guidelines alone , were total cholesterol -0.02 mmol/l ( -0.09 - 0.06 ) , systolic blood pressure -0.4 mmHg ( -1.6 - 0.8 ) , diastolic blood pressure -0.4 mmHg ( -1.5 - 0.7 ) and Framingham 10-year risk score -0.2 % ( -0.5 - 0.1 ) . CONCLUSIONS Systemic computerized routine provision of CHD risk profiles in addition to guidelines does not significantly improve risk factors for CHD in patients on cART Background There is nonoptimal adherence of general practitioners ( GPs ) and patients to cardiovascular risk reducing interventions . GPs find it difficult to assimilate multiple risk factors into an accurate assessment of cardiovascular risk . In addition , communicating cardiovascular risk to patients has proved to be difficult . Aims Improving primary prevention of cardiovascular disease ( CVD ) in primary care by enhancing patient involvement in the use of a decision support tool . Design Cluster r and omized trial . Methods Thirty-four GPs included patients ( 40 - 75 years old ) without CVD . In an interactive , small group training session lasting 4h , the GPs in the intervention group were trained to use the guidelines on cardiovascular risk and a decision support tool . The control group received educational material s about the guidelines on paper .  GPs ’ clinical performance and patients ’ risk perception and self-reported lifestyles were measured at baseline and after 6 months . Results Thirty-four GPs recorded 490 consultations , 276 in the intervention and 214 in the control group . After 6 months , no significant effect of the intervention on the GPs ’ performance or the patients ’ risk perception was found . There was only an effect on self-reported lifestyle , in that more men in the intervention group than in the control group increased their physical activity ( odds ratio 3.8 , 95 % confidence interval 1.7–8.7 ) . Conclusion The 4-h interactive , small group training did not guarantee correct application of the decision support tool and as such failed to improve GPs ’ performance or correct patients ’ risk perception . The positive effect on physical activity justifies further research on patient involvement . Eur J Cardiovasc Prev Rehabil 14 : 44 - 50 © 2007 The European Society of 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 Background Trials evaluating the effects of interventions usually provide little insight into the factors responsible for ( lack of ) changes in desired outcomes . A process evaluation alongside a trial can shed light on the mechanisms responsible for the outcomes of a trial . The aim of this study was to investigate exposure to and experiences with a computerized decision support system ( CDSS ) intervention , in order to gain insight into the intervention ’s impact and to provide suggestions for improvement . Methods A process evaluation was conducted as part of a large-scale cluster-r and omized controlled trial investigating the effects of the CDSS NHGDoc on quality of care . Data on exposure to and experiences with the intervention were collected during the trial period among participants in both the intervention and control group - whenever applicable - by means of the NHGDoc server and an electronic question naire . Multiple data were analyzed using descriptive statistics . Results Ninety-nine percent ( n = 229 ) of the included practice s generated data for the NHGDoc  server and 50 % ( n = 116 ) responded to the question naire : both general practitioners ( GPs ; n = 112 ; 49 % ) and practice nurses ( PNs ; n = 52 ; 37 % ) participated . The actual exposure to the NHGDoc system and specific heart failure module was limited with 52 % of the GPs and 42 % of the PNs reporting to either never or rarely use the system . Overall , users had a positive attitude towards CDSSs . The most perceived barriers to using NHGDoc were a lack of learning capacity of the system , the additional time and work it requires to use the CDSS , irrelevant alerts , too high intensity of alerts and insufficient knowledge regarding the system . Conclusions Several types of barriers may have negatively affected the impact of the intervention . Although users are generally positive about CDSSs , a large share of them is insufficiently aware of the functions of NHGDoc and , finds the decision support not always useful or relevant and difficult to integrate into daily practice . In design ing CDSS interventions we suggest to more intensely involve the end-users and increase the system ’s flexibility and learning capacity . To improve implementation a proper introduction of a CDSS among its target group including adequate training is advocated . Trial registration Clinical trials NCT01773057 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 OBJECTIVE To evaluate the implementation of clinical guidelines for hypertension in general practice by use of a computer-based clinical decision support system ( CDSS ) and a specific implementation strategy . Evaluation of patient outcome . DESIGN R and omised study with health centres as units . The intervention group had the CDSS installed and made ready for use , doctors and assistants were trained and received a user-manual , the doctors were offered telephone repetitions , a seminar in risk intervention and , at the same seminar , further demonstration of the CDSS . The doctors received baseline registration s with information of how they treated their own hypertensive patients , and use of the CDSS was checked repeatedly . SETTING General practice in Sør- and Nord-Trøndelag counties in Norway , 380,000 inhabitants . PARTICIPANTS Seventeen health centres with 24 doctors and 984 patients in the intervention group . Data from 879 patients used in the final analyses . Twelve health centres with 29 doctors and 1255 patients in the control group . Data from 1119 patients used in the final analyses . MAIN OUTCOME MEASURES After an intervention period of 18 months , group differences in level of systolic and diastolic blood pressure , serum cholesterol , body mass index , and risk score for myocardial infa rct ion were calculated , as well as group differences in fractions of smokers . RESULTS Significant group difference in favour of intervention group : diastolic blood pressure 1 mmHg ( 95 % CI -1.89 , -0.17 ) . However , a significant baseline difference in systolic blood pressure in favour of control group of 2.7 mmHg ( 95 % CI 1.0 , 4.5 ) had been reduced to 1.2 mmHg ( 95 % CI -0.6 , 3.0 ) after intervention . CONCLUSION Implementation of clinical guidelines in the treatment of hypertensive patients in general practice by means of a CDSS and several other procedures for implementation did not affect patient outcome in any clinical ly significant way Background Cardiovascular diseases ( CVD ) are responsible for significant morbidity , premature mortality , and economic burden . Despite established evidence that supports the use of preventive medications among patients at high CVD risk , treatment gaps remain . Building on prior evidence and a theoretical framework , a complex intervention has been design ed to address these gaps among high-risk , under-treated patients in the Australian primary care setting . This intervention comprises a general practice quality improvement tool incorporating clinical decision support and audit/feedback capabilities ; availability of a range of CVD polypills ( fixed-dose combinations of two blood pressure lowering agents , a statin ± aspirin ) for prescription when appropriate ; and access to a pharmacy-based program to support long-term medication adherence and lifestyle modification . Methods Following a systematic development process , the intervention will be evaluated in a pragmatic cluster r and omized controlled trial including 70 general practice s for a median period of 18 months . The 35 general practice s in the intervention group  will work with a nominated partner pharmacy , whereas those in the control group will provide usual care without access to the intervention tools . The primary outcome is the proportion of patients at high CVD risk who were inadequately treated at baseline who achieve target blood pressure ( BP ) and low-density lipoprotein cholesterol ( LDL-C ) levels at the study end . The outcomes will be analyzed using data from electronic medical records , utilizing a vali date d extraction tool . Detailed process and economic evaluations will also be performed . Discussion The study intends to establish evidence about an intervention that combines technological innovation with team collaboration between patients , pharmacists , and general practitioners ( GPs ) for CVD prevention . Trial registration Australian New Zeal and Clinical Trials Registry 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 To examine the performance of ' the Framingham 's general CVD algorithm ' in estimating 5-year risk of cardiovascular disease ( CVD ) and coronary heart disease ( CHD )  in an adult Middle Eastern community . METHODS In a population -based prospect i ve cohort , the Tehran Lipid and Glucose Study ( TLGS ) , CVD risk estimates were calculated for 3838 individuals ( 2183 women ) free of CVD at baseline . RESULTS Over 8.6 years , there were 119 CVD ( 106 CHD ) events among women , and 164 ( 137 ) among men aged ≥ 30 years . St and ard risk factors [ age , systolic blood pressure ( SBP ) , antihypertensive treatment , total and high-density lipoprotein cholesterol , smoking and diabetes mellitus ] , measured at baseline , were significantly related to the incidence of CVD . The only exception , lack of significance for coefficients of SBP among women , was attributable to collinearity between age and SBP . For most risk factors , hazard ratios ( HRs ) for CVD were similar for the TLGS and the Framingham cohorts ' participants . Few exceptions were lower HR for SBP among TLGS ' women and lower HR for age among TLGS ' men . The Framingham equations quite correctly discriminated participants [ C statistic : CVD , 0.818 ( women ) and 0.774 ( men ) ; CHD : 0.822 ( women ) and 0.751 ( men ) ] with good calibration ( all calibration χ(2 ) values < 15 , ps > 0.1 ) . DISCUSSION AND CONCLUSIONS The Framingham 's CVD algorithm was effective at ranking individuals and could be used to quantify risk and to guide preventive care in Iranian adults . For regions without established cohort , recalibration using risk factors and CVD ( CHD ) rates may be an effective method to develop CVD ( CHD ) risk prediction algorithms for local practice Background A pilot project cardiovascular prevention was implemented in S and well ( West Midl and s , UK ) . This used electronic primary care records to identify untreated patients at high risk of cardiovascular disease then invited these high risk patients for assessment by a nurse in their own general practice . Those found to be eligible for treatment were offered treatment . During the pilot a higher proportion of high risk patients were started on treatment in the intervention practice s than in control practice s. Following the apparent success of the prevention project , it was intended to extend the service to all practice s across the S and well area . However the pilot project was not a robust evaluation . There was a need for an efficient evaluation that would not disrupt the planned rollout of the project . Methods / design Project nurses will sequentially implement targeted cardiovascular case finding in a phased way across all general practice s , with the sequence of general practice s determined r and omly . This is a stepped wedge r and omised controlled trial design . The target population is patients aged 35 to 74 , without diabetes or cardiovascular disease whose ten-year cardiovascular risk , ( determined from data in their electronic records ) is ≥20 % . The primary outcome is the number of high risk patients started on treatment , because these data could be efficiently obtained from electronic primary care records . From this we can determine the effects of the case finding programme on the proportion of high risk patients started on treatment in practice s before and after implementation of targeted case finding . Cost-effectiveness will be modelled from the predicted effects of treatments on cardiovascular events and associated health service costs . Alongside the implementation it is intended to interview clinical staff and patients who participated in the programme in order to determine acceptability to patients and clinicians . Practical considerations meant that 26 practice s in S and well could be r and omised , including about 6,250 patients at high risk of cardiovascular disease . This gives sufficient power for evaluation . Discussion It is possible to design a stepped wedge r and omised controlled trial using routine data to determine the primary outcome to evaluate implementation of a cardiovascular prevention programme Introduction : The promise of Clinical Decision Support ( CDS ) has always been to transform patient care and improve patient outcomes through the delivery of timely and appropriate recommendations that are patient specific and , more often than not , are appropriately actionable . However , the users of CDS — providers — are frequently bombarded with inappropriate and inapplicable CDS that often are not informational , not integrated into the workflow , not patient specific , and that may present out of date and irrelevant recommendations . Methods : The integrated clinical prediction rule ( iCPR ) project was a r and omized clinical trial ( RCT ) conducted to determine if a novel form of CDS , i.e. , clinical prediction rules ( CPRs ) , could be efficiently integrated into workflow and result in changes in outcomes ( e.g. , antibiotic ordering ) when embedded within a commercial electronic health record ( EHR ) . We use the lessons learned from the iCPR project to illustrate a framework for constructing usable , useful , and effective actionable CDS while employing off-the-shelf functionality in a production system . Innovations that make up the framework combine the following : ( 1 ) active and actionable decision support , ( 2 ) multiple rounds of usability testing with iterative development for user acceptance , ( 3 ) numerous context sensitive triggers , ( 4 ) dedicated training and support for users of the CDS tool for user adoption , and ( 5 ) support from clinical and administrative leadership . We define “ context sensitive triggers ” as being workflow events ( i.e. , context ) that result in a CDS intervention . Discussion : Success of the framework can be measured by CDS adoption ( i.e. , intervention is being used ) , acceptance ( compliance with recommendations ) , and clinical outcomes ( where appropriate ) . This framework may have broader implication s for the deployment of Health Information Technology ( HIT ) . Results and Conclusion : iCPR was well adopted(57.4 % of users ) and accepted ( 42.7 % of users ) . Usability testing identified and fixed many issues before the iCPR RCT . The level of leadership support and clinical guidance for iCPR was key in establishing a culture of acceptance for both the tool and its recommendations contributing to adoption and acceptance . The dedicated training and support lead to the majority of the residents reporting a high level of comfort with both iCPR tools strep pharyngitis ( 64.4 percent ) and pneumonia ( 62.7 percent ) as well as a high likelihood of using the tools in the future . A surprising framework addition result ed from usability testing : context sensitive triggers
Results were inconsistent for changes in CVD risk factors such as systolic and diastolic blood pressure , total and low-density lipoprotein cholesterol , and hemoglobin A1C levels .
CONCLUSIONS CDSSs are effective in improving clinician practice s related to screening and other preventive care services , clinical tests , and treatments .
CONTEXT Clinical decision support systems ( CDSSs ) can help clinicians assess cardiovascular disease ( CVD ) risk and manage CVD risk factors by providing tailored assessment s and treatment recommendations based on individual patient data .
The goal of this systematic review was to examine the effectiveness of CDSSs in improving screening for CVD risk factors , practice s for CVD-related preventive care services such as clinical tests and prescribed treatments , and management of CVD risk factors .
