    Input: BACKGROUND Heart failure treatment guidelines emphasize daily weight monitoring for patients with heart failure , but data to support this practice are lacking . Using a technology-based heart failure monitoring system , we determined whether daily reporting of weight and symptoms in patients with advanced heart failure would reduce rehospitalization and mortality rates despite aggressive guideline -driven heart failure care . METHODS This was a r and omized , controlled trial . Patients hospitalized with New York Heart Association class III or IV heart failure , with a left ventricular ejection fraction < or = 35 % were r and omized to receive heart failure program care or heart failure program care plus the AlereNet system ( Alere Medical , Reno , Nev ) and followed-up for 6 months . The primary end point was 6-month hospital readmission rate . Secondary end points included mortality , heart failure hospitalization readmission rate , emergency room visitation rate , and quality of life . RESULTS Two hundred eighty patients from 16 heart failure centers across the United States were r and omized : 138 received the  AlereNet system and 142 received st and ard care .  Mean age was 59 + /- 15 years and 68 % were male . The population had very advanced heart failure , New York Heart Association class III ( 75 % ) or IV ( 25 % ) , as evidence d by serum norepinepherine levels , 6-minute walk distance and outcomes .  No differences in hospitalization rates were observed . There was a 56.2 % reduction in mortality ( P < .003 ) for patients r and omized to the AlereNet group . CONCLUSIONS This is the largest multicenter , r and omized trial of a technology-based daily weight and symptom-monitoring system for patients with advanced heart failure . Despite no difference in the primary end point of rehospitalization rates , mortality was significantly reduced for patients r and omized to the AlereNet system without an increase in utilization , despite specialized and aggressive heart failure care in both groups BACKGROUND Case management is believed to promote continuity of care and decrease hospitalization rates , although few controlled trials have tested this approach . OBJECTIVE To assess the effectiveness of a st and ardized telephonic case-management intervention in decreasing re source use in patients with chronic heart failure . METHODS A r and omized controlled clinical trial was used to assess the effect of telephonic case management on re source use .  Patients were identified at hospitalization and assigned to receive 6 months of intervention ( n = 130 ) or usual care ( n = 228 ) based on the group to which their physician was r and omized .  Hospitalization rates , readmission rates , hospital days , days to first rehospitalization , multiple readmissions , emergency department visits , inpatient costs , outpatient re source use , and patient satisfaction were measured at 3 and 6 months . RESULTS The heart failure hospitalization rate was 45.7 % lower in the intervention group at 3 months ( P = .03 ) and 47.8 % lower at 6 months ( P = .01 ) . Heart failure hospital days ( P = .03 ) and multiple readmissions ( P = .03 ) were significantly lower in the intervention group at 6 months . Inpatient heart failure costs were 45.5 % lower at 6 months ( P = .04 ) . A cost saving was realized even after intervention costs were deducted . There was no evidence of cost shifting to the outpatient setting . Patient satisfaction with care was higher in the intervention group . CONCLUSIONS The reduction in hospitalizations , costs , and other re source use achieved using st and ardized telephonic case management in the early months after a heart failure admission is greater than that usually achieved with pharmaceutical therapy and comparable with other disease management approaches Background — The long-term impact of chronic heart failure management programs over the typical life span of affected individuals is unknown . Methods and Results — The effects of a nurse-led , multidisciplinary , home-based intervention ( HBI ) in a typically elderly cohort of patients with chronic heart failure initially r and omized to either HBI ( n=149 ) or usual postdischarge care ( UC ) ( n=148 ) after a short-term hospitalization were studied for up to 10 years of follow-up ( minimum 7.5 years of follow-up ) . Study end points were all-cause mortality , event-free survival ( event was defined as death or unplanned hospitalization ) , recurrent hospital stay , and cost per life-year gained . Median survival in the HBI cohort was almost twice that of UC ( 40 versus 22 months ; P<0.001 ) , with fewer deaths overall ( HBI , 77 % versus 89 % ; adjusted relative risk , 0.74 ; 95 % CI , 0.53 to 0.80 ; P<0.001 ) . HBI was associated with prolonged event-free survival ( median , 7 versus 4 months ; P<0.01 ) . HBI patients had more unplanned readmissions ( 560 versus 550 ) but took 7 years to overtake UC ; the rates of readmission ( 2.04±3.23 versus 3.66±7.62 admissions ; P<0.05 ) and related hospital stay ( 14.8±23.0 versus 28.4±53.4 days per patient per year ; P<0.05 ) were significantly lower in the HBI group . HBI was associated with 120 more life-years per 100 patients treated compared with UC ( 405 versus 285 years ) at a cost of $ 1729 per additional life-year gained when we accounted for healthcare costs including the HBI . Conclusions — In altering the natural history of chronic heart failure relative to UC ( via prolonged survival and reduced frequency of recurrent hospitalization  ) , HBI is a remarkably cost- and time-effective strategy over the longer term Background Structured care is proposed as a lever for improving care for patients with chronic conditions . The purpose of this study was to explore the associations of structured care characteristics , derived from the Chronic Care Model , with health-related quality of life ( HRQOL ) and optimal clinical management in chronic heart failure ( CHF ) patients in primary care , as well as the association between optimal management and HRQOL . Methods Cross-sectional observational study using multi-level r and om-coefficient analyses of a representative sample of 357 patients diagnosed with CHF from 42 primary care practice s in the Netherl and s. We combined individual medical record data with patient and physician question naires . Results There was large variation in the levels and presence of structured care elements . A 91 % of physicians indicated that next appointments for CHF patients were made immediately after visits , while 11 % indicated that reminders on CHF management were periodically received in their practice . Few associations were found between the organizational characteristics and optimal treatment or HRQOL . Optimal pharmacological treatment  related to better quality of life ( β = -11.5 , P < .0001 ) . Also , more lifestyle advice  was given in practice s with an appointment system allowing contact with more than one professional during the encounter ( β = 1.0 , P = .04 ) . Conclusion HRQOL and treatment quality in CHF patients were not consistently associated with characteristics of structured care in primary care practice AIMS To test the effect of education and support by a nurse on self-care and re source utilization in patients with heart failure . METHODS A total of 179 patients ( mean age 73 , 58 % male , NYHA III-IV ) hospitalized with heart failure were evaluated prospect ively . Patients were r and omized to the study intervention or to ' care as usual '  . The supportive educative intervention consisted of intensive , systematic and planned education by a study nurse about the consequences of heart failure in daily life , using a st and ard nursing care plan developed by the research ers for older patients with heart failure . Education and support took place during the hospital stay and at a home visit within a week of discharge . Data were collected on self-care abilities , self-care behaviour , readmissions , visits to the emergency heart centre and use of other health care re sources . RESULTS Education and support from a nurse in a hospital setting and at home significantly increases self-care behaviour in patients with heart failure . Patients from both the intervention and the control group increased their self-care behaviour within 1 month of discharge , but the increase in the intervention group was significantly more after 1 month . Although self-care behaviour in both groups decreased during the following 8 months , the increase from baseline remained statistically significant in the intervention group , but not in the control group . No significant effects on re source utilization were found . CONCLUSIONS Intensive , systematic , tailored and planned education and support by a nurse results in an increase in patients ' self-care behaviour . No significant effects were found on use of health care re sources . Additional organisational changes , such as longer follow-up and the availability of a heart failure specialist would probably enhance the effects of education and support Background .The high cost of caring for patients with congestive heart failure ( CHF ) results primarily from frequent hospital readmissions for exacerbations . Home nurse visits after discharge can reduce readmissions , but the intervention costs are high . Objectives .To compare the effectiveness of three hospital discharge care models for reducing CHF-related readmission charges : 1 ) home telecare delivered via a 2-way video-conference device with an integrated electronic stethoscope ; 2 ) nurse telephone calls ; and 3 ) usual outpatient care . Research Design . One-year r and omized trial . Subjects . English-speaking patients 40 years of age and older with a primary hospital admission diagnosis of CHF . Measures .Our primary outcome was CHF-related readmission charges during a 6-month period after r and omization . Secondary outcomes included all-cause readmissions , emergency department ( ED ) visits , and associated charges . Results .Thirty-seven subjects were r and omized : 13 to home telecare , 12 each telephone care and 12 to usual care .  Mean CHF-related readmission charges were 86 % lower in the telecare group ( $ 5850 , SD $ 21,094 ) and 84 % lower in the telephone group ( $ 7320 , SD $ 24,440 ) than in the usual care group ( $ 44,479 , SD $ 121,214 ) . However , the between-group difference was not statistically significant . Both intervention groups had significantly fewer CHF-related ED visits ( P = 0.0342 ) and charges ( P = 0.0487 ) than the usual care group . Trends favoring both interventions were noted for all other utilization outcomes . Conclusions .Substantial reductions in hospital readmissions , emergency visits , and cost of care for patients with CHF might be achieved by widespread deployment of distance technologies to provide posthospitalization monitoring . Home telecare may not offer incremental benefit beyond telephone follow-up and is more expensive Abstract Objectives : To determine whether specialist nurse intervention improves outcome in patients with chronic heart failure . Design : R and omised controlled trial . Setting : Acute medical admissions unit in a teaching hospital . Participants : 165 patients admitted with heart failure due to left ventricular systolic dysfunction . The intervention started before discharge and continued thereafter with home visits for up to 1 year . Main outcome measures : Time to first event analysis of death from all causes or readmission to hospital with worsening heart failure . Results : 31 patients ( 37 % ) in the intervention group died or were readmitted with heart failure compared with 45 ( 53 % ) in the usual care group ( hazard ratio=0.61 , 95 % confidence interval 0.33 to 0.96).Compared with usual care , patients in the intervention group had fewer readmissions for any reason ( 86 v 114 , P=0.018 ) , fewer admissions for heart failure ( 19 v 45 , P<0.001 ) and spent fewer days in hospital for heart failure ( mean 3.43 v 7.46 days , P=0.0051 ) . Conclusions : Specially trained nurses can improve the outcome of patients admitted to hospital with heart failure . What is already known on this topic Studies have suggested that nurse intervention may reduce readmission in patients with heart failure What this study adds Home based intervention from nurses reduces readmissions for worsening heart failure Regular contact to review treatment and patient education are likely to contribute to this OBJECTIVE This study compared the effectiveness and cost/utility ratio between a heart failure ( HF ) management program delivered by day-hospital ( DH ) and usual care in chronic heart failure ( CHF ) out patients . BACKGROUND Previous studies showed that about 50 % of readmissions for CHF can be prevented by a multidisciplinary approach . However , the performance , effectiveness , and cost/utility ratio of a process of HF outpatient management related to evidence -based medicine have not been considered . METHODS A total of 234 prospect i ve patients discharged by a HF Unit were r and omized to two management strategies : 122 patients to usual community care and 112 patients to a HF management program delivered by the DH .  Management ( rate of readmissions , therapeutic interventions ) , functional parameters ( New York Heart Association [ NYHA ] functional class , left ventricular diameters , and ejection fraction , deceleration time of early diastolic mitral flow , peak oxygen uptake , and mitral regurgitation ) and hard outcomes ( cardiac death and urgent cardiac transplantation ) were evaluated . The cost/utility ratios of the two strategies were compared . RESULTS After 12 + /- 3 months of follow-up , the individual rate access in DH was 5.5 + /- 3.8 days . The DH subjects were readmitted to the hospital less frequently than were the usual-care group patients ( 13 vs. 78 , p < 0.00001 ) . Patients allocated to usual-care management showed heterogeneous changes in NYHA functional class ( 13 % improved and 16 % worsened p = NS ) ; In contrast , the DH group showed significant changes in NYHA functional class ( 23 % improved and 11 % worsened , p < 0.0 
    Output:
    
The individual CAS characteristics associated with CHF intervention effectiveness were learning , self-organization , and co-evolution , a finding different from our previously published analysis of interventions for diabetes .
We suggest this difference may be related to the degree of uncertainty involved in caring for patients with diabetes versus CHF .
