    Input: OBJECTIVE To assess the impact and cost-effectiveness of two information-based provider reminder interventions design ed to improve self-care management and outcomes of heart failure ( HF ) patients . DATA SOURCES / STUDY SETTING Interview and agency administrative data on 628 home care patients with a primary diagnosis of HF . STUDY DESIGN Patients were treated by nurses r and omly assigned to usual care or one of two intervention groups . The basic intervention was an e-mail to the patient 's nurse highlighting six HF-specific clinical recommendations . The augmented intervention supplemented the initial nurse reminder with additional clinician and patient re sources . DATA COLLECTION Patient interviews were conducted 45 days post admission to measure self-management behaviors , HF-specific outcomes ( Kansas City Cardiomyopathy Question naire-KCCQ ) , health-related quality of life ( EuroQoL ) , and service use . PRINCIPAL FINDINGS Both interventions improved the mean KCCQ summary score ( 15.3 and 12.9 percent , respectively ) relative to usual care ( p < or = .05 ) . The basic intervention also yielded a higher EuroQoL score relative to usual care ( p < or = .05 ) . In addition , the interventions had a positive impact on medication knowledge , diet , and weight monitoring . The basic intervention was more cost-effective than the augmented intervention in improving clinical outcomes . CONCLUSIONS This study demonstrates the positive impact of targeting evidence -based computer reminders to home health nurses to improve patient self-care behaviors , knowledge , and clinical outcomes . It also advances the field 's limited underst and ing of the cost-effectiveness of selected strategies for translating research into practice BACKGROUND There is increased pressure on primary care physicians to monitor oral anticoagulation . OBJECTIVE To test the null hypothesis that oral anticoagulation care can be provided at least as well in primary care through a nurse-led clinic , involving near-patient testing and computerized decision support software , compared with routine hospital management based on a variety of clinical outcome measures . METHODS A r and omized , controlled trial in 12 primary care practice s in Birmingham , Engl and ( 9 intervention and 3 control ) . Two control population s were used :  patients individually r and omly allocated as controls in the intervention practice s ( intra practice controls ) and all patients in control practice s ( inter practice controls ) . Intervention practice s ' patients were r and omized to the intervention ( practice -based anticoagulation clinic ) or control ( hospital clinic ) group . The main outcome measure was therapeutic control of the international normalized ratio . RESULTS Three hundred sixty-seven patients were recruited ( 122 intervention patients , 102 intra practice control patients , and 143 inter practice control patients ) . St and ard measures of control of the international normalized ratio ( point prevalence ) showed no significant difference between the intervention and control groups . Data on proportion of time spent in the international normalized ratio range showed significant improvement for patients in the intervention group ( paired t test , P = .008 ) . CONCLUSIONS Nurse-led anticoagulation clinics can be implemented in novice primary care setting s by means of computerized decision support software and near-patient testing . Care given by this model is at least as good as routine hospital follow-up . The model is generalizable to primary health care centers operating in developed health care systems A system has been constructed to evaluate the design , implementation , and analysis of  r and omized control trials ( RCT ) . The degree of quadruple blinding ( the r and omization process , the physicians and patients as to therapy , and the physicians as to ongoing results ) is considered to be the most important aspect of any trial . The analytic techniques are scored with the same emphasis as is placed on the control of bias in the planning and implementation of the studies . Description of the patient and treatment material s and the measurement of various controls of quality have less weight . An index of quality of a RCT is proposed with its pros and cons . If published papers were to approximate these principles , there would be a marked improvement in the quality of r and omized control trials . Finally , a reasonable st and ard design and conduct of trials will facilitate the interpretation of those with conflicting results and help in making valid combinations of undersized trials We conducted a prospect i ve study of an electronic clinical reminder system in an academic medical center-based human immunodeficiency virus ( HIV ) specialty clinic . Published performance indicators were used to examine adherence to HIV practice guidelines before and after its implementation for 1204 patients . More than 90 % of patients received  CD4 cell count and HIV type 1 ( HIV-1 ) RNA level monitoring  every 3 - 6 months during both time periods , and approximately 80 % of patients with a CD4 cell count nadir of < 350 cells/mm(3 ) received highly active antiretroviral therapy . Patients were significantly more likely to receive prophylaxis against Mycobacterium avium complex ( hazard ratio , 3.84 ; 95 % confidence interval [ CI ] , 1.58 - 9.31 ; P=.003 ) , to undergo annual cervical carcinoma screening ( OR , 2.09 ; 95 % CI , 1.04 - 4.16 ; P=.04 ) , and to undergo serological screening for Toxoplasma gondii ( odds ratio [ OR ] , 1.86 ; 95 % CI , 1.05 - 3.27 ; P=.03 ) and syphilis infection ( OR , 3.71 ; 95 % CI , 2.37 - 5.81 ; P<.0001 ) . HIV clinical reminders delivered at the time that HIV care is provided were associated with more timely initiation of recommended practice BACKGROUND We compared the efficacy of a computer-generated prompt sheet placed on the front of patients ' charts with a patient-carried prompt card to remind physicians to perform selected health maintenance items . METHODS A r and omized prospect i ve single-blind study was performed in private practice offices in rural eastern North Carolina , with 28 family practitioners and nine general internists participating . Twenty-two physicians were r and omized to the computer prompt group and 22 to the card prompt group .  Four physicians in the computer group did not complete the study because of computer software problems , and three physicians did not complete the study because their limited staff was unable to enter patient data into the computer . Before the intervention , 20 patient charts ( 10 males and 10 females ) from each physician were audited for the performance of influenza vaccinations , stool for occult blood , pap smears , breast examinations performed by the physicians , and mammograms . One year after the intervention was instituted , chart audits for the above five items were done again on 20 different patient charts for each physician . RESULTS There was a 7 % increase in the performance of influenza vaccinations  in the card group ( 17 % vs 24 % ) compared with a 6 % increase in the computer group ( 20 % vs 26 % ) . There was a 5 % decrease in the performance of stool for occult blood in the card group ( 28 % vs 23 % ) compared with a 1 % increase in the computer group ( 30 % vs 31 % ) . There was an 11 % decrease in the performance of pap smears in the card group ( 26 % vs 15 % ) compared with a 3 % increase in the computer group ( 23 % vs 26 % ) . There was a 2 % decrease in the performance of breast examinations by the physician in the card group ( 35 % vs 33 % ) compared with a 3 % increase in the computer group ( 30 % vs 33 % ) . Finally , there was a 3 % increase in the performance of mammograms in the card group ( 22 % vs 25 % ) compared with an 11 % increase in the computer group ( 15 % vs 26 % ) . CONCLUSIONS Our data show a greater increase in performance of health maintenance items in the computer-prompted group . The performance of stool for occult blood , pap smears , breast examinations performed by the physician , and mammograms were increased more in the computer-prompted group than in the card group . However , there was not a statistically significant difference after intervention for any of the audited health maintenance items for either the computer group or the card group . Overall , health maintenance measures were performed in only a minority of appropriate patients OBJECTIVE To assess the impact of an automated intraoperative alert to redose prophylactic antibiotics in prolonged cardiac operations . DESIGN R and omized , controlled , evaluator-blinded trial . SETTING University-affiliated hospital . PATIENTS Patients undergoing cardiac surgery that lasted more than 4 hours after the preoperative administration of cefazolin , unless they were receiving therapeutic antibiotics at the time of surgery . INTERVENTION R and omization to an audible and visual reminder on the operating room computer console at 225 minutes after the administration of preoperative antibiotics ( reminder group , n = 137 ) or control ( n = 136 ) . After another 30 minutes , the circulating nurse was required to indicate whether a follow-up dose of antibiotics had been administered . RESULTS Intraoperative redosing was significantly more frequent in the reminder group ( 93 of 137 ; 68 % ) than in the control group ( 55 of 136 ; 40 % ) ( adjusted odds ratio , 3.31 ; 95 % confidence interval , 1.97 to 5.56 ; P < .0001 ) . The impact of the reminder was even greater when compared with the 6 months preceding the study period ( 129 of 480 ; 27 % ; P < .001 ) , suggesting some spillover effect on the control group . Redosing was formally declined for 19 of the 44 patients in the reminder group without redosing . The rate of surgical-site infection in the reminder group ( 5 of 137 ; 4 % ) was similar to that in the control group ( 8 of 136 ; 6 % ; P = .42 ) , but significantly lower than that in the pre- study period ( 48 of 480 ; 10 % ; P = .02 ) . CONCLUSION The use of an automatic reminder system in the operating room improved compliance with guidelines on perioperative antibiotic prophylaxis Abstract Objectives : To investigate the effect of a computer based clinical decision support system and a risk chart on absolute cardiovascular risk , blood pressure , and prescribing of cardiovascular drugs in hypertensive patients . Design : Cluster r and omised controlled trial . Setting : 27 general practice s in Avon . Participants : 614 patients aged between 60 and 79 years with high blood pressure . Interventions : Patients were r and omised to computer based clinical decision support system plus cardiovascular risk chart ; cardiovascular risk chart alone ; or usual care . Main outcome measures : Percentage of patients in each group with a five year cardiovascular risk≥10 % , systolic blood pressure , diastolic blood pressure , prescribing of cardiovascular drugs . Results : Patients in the computer based clinical decision support system and chart only groups were no more likely to have cardiovascular risk reduced to below 10 % than patients receiving usual care . Patients in the computer based clinical decision support group were more likely to have a cardiovascular risk≥10 % than chart only patients , odds ratio 2.3 ( 95 % confidence interval 1.1 to 4.8 ) . The chart only group had significantly lower systolic blood pressure compared with the usual care group ( difference in means−4.6 mm Hg ( 95 % confidence interval−8.4 to−0.8 ) . Reduction of diastolic blood pressure did not differ between the three groups . The chart only group were twice as likely to be prescribed two classes of cardiovascular drugs and over three times as likely to be prescribed three or more classes of drugs compared with the other groups . Conclusions : The computer based clinical decision support system did not confer any benefit in absolute risk reduction or blood pressure control and requires further development and evaluation before use in clinical care can be recommended . Use of chart guidelines are associated with a potentially important reduction in systolic blood pressure AIMS --To compare the effectiveness of three computerised systems that are currently used for assisting warfarin control in out patients with the customary dosing method used by experienced medical staff . METHODS --A pilot r and omised study of three systems with a follow up independently r and omised study of two of these was made on 186 patients receiving long term treatment or who had recently started warfarin treatment and had been discharged from hospital . RESULTS --All three computerised systems seemed to give satisfactory control compared with the traditional dosing method . For patients receiving more intensive treatment with an assigned target range of 3.0 - 4.5 computerised dosage programs achieved significantly better control ; the medical staff undertreated such patients almost 50 % of the time . CONCLUSION --Computer based programs can assist outpatient anticoagulant control with warfarin during both early and long term treatment . For most patients the control achieved is as good as that obtained by the customary method of dosing , by experienced clinic doctors , although the latter tend to be too conservative when dosing patients within the intense target range of 3.0 to 4.5 International Normalised Ratio ( INR ) . The computers were significantly more successful in this higher range OBJECTIVE To evaluate whether an electronic reminder integrated into a routine computer system increases the use of antiplatelet drugs  for diabetic patients among Italian general practitioners ( GPs ) . RESEARCH DESIGN AND METHODS A r and omized controlled trial was carried out among 300 GPs and their patients selected from the Health Search Data base . Among these , 150 GPs ( intervention group ) received instructions to activate an electronic reminder plus a letter summarizing the beneficial effects of antiplatelet drugs in diabetic patients with at least one additional cardiovascular risk factor ( " high risk " ) , whereas the other 150 GPs ( control group ) received only the letter . The electronic reminder , integrated into a
