    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 Telemonitoring of patients with chronic heart failure ( CHF ) is an emerging concept to detect early warning signs of impending acute decompensation in order to prevent hospitalization . Objective The goal of the MOBIle TELemonitoring in Heart Failure Patients Study ( MOBITEL ) was to evaluate the impact of home-based telemonitoring using Internet and mobile phone technology on the outcome of heart failure patients after an episode of acute decompensation . Methods Patients were r and omly allocated to pharmacological treatment ( control group ) or to pharmacological treatment with telemedical surveillance for 6 months ( tele group ) . Patients r and omized into the tele group were equipped with mobile phone – based patient terminals for data acquisition and data transmission to the monitoring center . Study physicians had continuous access to the data via a secure Web portal . If transmitted values went outside individually adjustable borders , study physicians were sent an email alert . Primary endpoint was hospitalization for worsening CHF or death from cardiovascular cause . Results The study was stopped after r and omization of 120 patients ( 85 male , 35 female ) ; median age was 66 years ( IQR 62 - 72 ) . The control group comprised 54 patients ( 39 male , 15 female ) with a median age of 67 years ( IQR 61 - 72 ) , and the tele group included 54 patients ( 40 male , 14 female ) with a median age of 65 years ( IQR 62 - 72 ) . There was no significant difference between groups with regard to baseline characteristics . Twelve tele group patients were unable to begin data transmission due to the inability of these patients to properly operate the mobile phone ( “ never beginners ” ) . Four patients did not finish the study due to personal reasons . Intention-to-treat analysis at study end indicated that 18 control group patients ( 33 % ) reached the primary endpoint ( 1 death , 17 hospitalizations ) , compared with 11 tele group patients ( 17 % , 0 deaths , 11 hospitalizations ; relative risk reduction 50 % , 95 % CI 3 - 74 % , P = .06 ) . Per- protocol analysis revealed that 15 % of tele group patients ( 0 deaths , 8 hospitalizations ) reached the primary endpoint ( relative risk reduction 54 % , 95 % CI 7 - 79 % , P= .04 ) . NYHA class improved by one class in tele group patients only ( P < .001 ) . Tele group patients who were hospitalized for worsening heart failure during the study had a significantly shorter length of stay ( median 6.5 days , IQR 5.5 - 8.3 ) compared with control group patients ( median 10.0 days , IQR 7.0 - 13.0 ; P= .04 ) . The event rate of never beginners was not higher than the event rate of control group patients . Conclusions Telemonitoring using mobile phones as patient terminals has the potential to reduce frequency and duration of heart failure hospitalizations . Providing elderly patients with an adequate user interface for daily data acquisition remains a challenging component of such a concept OBJECTIVES We sought to determine whether a multidisciplinary outpatient management program decreases  chronic heart failure ( CHF )  hospital readmissions and mortality over a six-month period . BACKGROUND Hospital admission for CHF is an important problem amenable to improved outpatient management . METHODS Two hundred patients hospitalized with CHF at increased risk of hospital readmission were r and omized to a multidisciplinary program or usual care . A study cardiologist and a CHF nurse evaluated each patient and made recommendations to the patient 's primary physician before r and omization . The intervention team consisted of a cardiologist , a CHF nurse , a telephone nurse coordinator and the patient 's primary physician . Contact with the patient was on a prespecified schedule . The CHF nurse followed an algorithm to adjust medications . Patients in the nonintervention group were followed as usual . The primary outcome was the composite of the number of CHF hospital admissions and deaths over six months , compared by using a log transformation t test by intention-to-treat analysis . RESULTS The median age of the study patients was 63.5 years , and 39.5 % were women . There were 43 CHF hospital admissions and 7 deaths in the intervention group , as compared with 59 CHF hospital admissions and 13 deaths in the nonintervention group ( p = 0.09 ) . The quality -of-life score , percentage of patients on target vasodilator therapy and percentage of patients compliant with diet recommendations were significantly better in the intervention group . Cost per patient , in 1998 U.S. dollars , was similar in both groups . CONCLUSIONS This study demonstrates that a six-month , multidisciplinary approach to CHF management can improve important clinical outcomes at a similar cost in recently hospitalized high-risk patients with CHF Remote monitoring ( RM ) of homebound heart failure ( HF ) patients has previously been shown to reduce hospital admissions . We conducted a pilot trial of ambulatory , non-homebound patients recently hospitalized for HF to determine whether RM could be successfully implemented in the ambulatory setting . Eligible patients from Massachusetts General Hospital ( n = 150 ) were r and omized to a control group ( n = 68 ) or to a group that was offered RM ( n = 82 ) . The participants transmitted vital signs data to a nurse who coordinated care with the physician over the course of the 6-month study . Participants in the RM program had a lower all-cause per person readmission rate ( mean = 0.64 , SD ± 0.87 ) compared to the usual care group ( mean = 0.73 , SD ± 1.51 ; P-value = .75 ) although the difference was not statistically significant . HF-related readmission rate was similarly reduced in participants . This pilot study demonstrates that RM can be successfully implemented in non-homebound HF patients and may reduce readmission rates BACKGROUND Few studies have examined the potential benefits of specialist nurse-led programs of care involving home and clinic-based follow-up to optimise the post-discharge management of chronic heart failure ( CHF ) . OBJECTIVE To determine the effectiveness of a hybrid program of clinic plus home-based intervention ( C+HBI ) in reducing recurrent hospitalisation in CHF patients . METHODS CHF patients with evidence of left ventricular systolic dysfunction admitted to two hospitals in Northern Engl and were assigned to a C+HBI lasting 6 months post-discharge ( n=58 ) or to usual , post-discharge care ( UC : n=48 ) via a cluster r and omization protocol . The co- primary endpoints were death or unplanned readmission ( event-free survival ) and rate of recurrent , all-cause readmission within 6 months of hospital discharge . RESULTS During study follow-up , more UC patients had an unplanned readmission for any cause ( 44 % vs. 22 % : P=0.019 , OR 1.95 95 % CI 1.10 - 3.48 ) whilst 7 ( 15 % ) versus 5 ( 9 % ) UC and C+HBI patients , respectively , died ( P = NS ) . Overall , 15 ( 26 % ) C+HBI versus 21 ( 44 % ) UC patients experienced a primary endpoint . C+HBI was associated with a non-significant , 45 % reduction in the risk of death or readmission when adjusting for potential confounders ( RR 0.55 , 95 % CI 0.28 - 1.08 : P=0.08 ) . Overall , C+HBI patients accumulated significantly fewer unplanned readmissions ( 15 vs. 45 : P<0.01 ) and days of recurrent hospital stay ( 108 vs. 459 days : P<0.01 ) . C+HBI was also associated with greater uptake of beta-blocker therapy ( 56 % vs. 18 % : P<0.001 ) and adherence to Na restrictions ( P<0.05 ) during 6-month follow-up . CONCLUSION This is the first r and omised study to specifically examine the impact of a hybrid , C+HBI program of care on hospital utilisation in patients with CHF . Its beneficial effects on recurrent readmission and event-free survival are consistent with those applying either a home or clinic-based approach OBJECTIVE To assess the effect of a telephone intervention to improve quality of life among patients with congestive heart failure ( CHF ) . STUDY DESIGN Prospect i ve r and omized study . METHODS Single-site recruitment of 458 patients using Veterans Health Administration care into a r and omized controlled trial with a 1-year preintervention data collection period and a 1-year intervention and follow-up period . To compensate for imbalanced study groups , propensity scores were included in adjusted models of quality of life , satisfaction with care , inpatient utilization , survival , and costs of care . RESULTS Patients aged 45 to 95 years participated in the study ; 22 % were of Hispanic race/ethnicity , and 7 % were African American . All but 5 were male , consistent with the older population among veterans . At baseline , 40 % were in Goldman Specific Activity Scale class I , 42 % were in class III , 6 % were in class II or IV , and 12 % were unclassified . Patients scored a mean ( SD ) of 14 ( 1.5 ) points below the norm on the physical component score . After the yearlong intervention , no differences in clinical outcomes were noted between the intervention group and the control group . The CHF-related costs were higher for the intervention group , as were overall costs that included the cost of the intervention . Intervention group patients reported better compliance with weight monitoring and exercise recommendations . CONCLUSIONS A risk-stratified intervention for patients with CHF result ed in potential behavioral improvements but no survival benefit . A high-cost high-intensity intervention may be required to improve survival for patients with CHF . Inclusion of the costs of interventions is recommended for future research ers The aim of this study was to determine whether using a teleheath system after discharge from formal home health services would improve clinical outcomes and self-management behaviors .  Patients were recruited from 10 home health agencies ( HHAs ) across the United States . All patients used the Health Buddy telehealth system  during formal home health services . Patients were r and omly assigned to either the telehealth group or the control group  upon
