    Input: 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 Heart failure ( HF ) is a major public health problem . Case management by nurses using telephone follow-up has been suggested as a convenient and effective mechanism to promote the self-management of HF . Similarly , a patient empowerment approach to the management of chronic disease has been suggested as one that may nurture self-management in individuals with chronic illness . OBJECTIVE The purpose of this study was to examine the effects of a telephone-delivered empowerment intervention ( EI ) on clinical ly and theoretically relevant outcomes in patients with HF , including purpose ful participation in goal attainment , self-management of HF , and perception of functional health . The EI was guided by Rogers ' Science of Unitary Human Beings person-environment process . METHODS A convenience sample of men and women aged 21 years and older with a clinical diagnosis of HF was obtained from a metropolitan hospital located in the southwestern United States . The participants were r and omly assigned to the control group ( n = 45 ) or EI group ( n = 45 ) . All participants received st and ardized HF patient education ; the intervention group also received an EI delivered through telephone follow-up calls from a registered nurse . Repeated- measures analysis of variance was used to evaluate intervention effects . RESULTS The telephone-delivered EI  facilitated self-management of HF through self-care activities in EI group members . CONCLUSION The knowledge gained from this study provides a beginning underst and ing of strategies to enhance health care providers ' ability to facilitate self-management of HF among patients diagnosed with HF 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 While there are data to support the use of comprehensive non-pharmacological intervention programs in patients with heart failure ( HF ) , other studies have not confirmed these positive findings . Substantial differences in the type and intensity of disease management programs make it impossible to draw definitive conclusions about the effectiveness , optimal timing and frequency of interventions . AIMS 1 . To determine the effectiveness of two interventions ( basic support vs. intensive support ) compared to ' care as usual ' in HF patients , on time to first major event ( HF readmission or death ) , quality of life and costs . 2 . To investigate the role of underlying mechanisms ( knowledge , beliefs , self-care behaviour , compliance ) on the effectiveness of the two interventions . METHODS This is a r and omised controlled trial in which 1050 patients with heart failure will be r and omised into three treatment arms : care as usual , basic education and support or intensive education and support . Outcomes of this study are ; time to first major event ( HF hospitalisation or death ) , quality of life ( Minnesota Living with HF Question naire , R AND 36 and Ladder of Life ) and costs . Data will be collected during initial admission and then 1 , 6 , 12 , and 18 months after discharge . In addition , data on knowledge , beliefs , self-care behaviour and compliance will be collected . RESULTS The study started in January 2002 and results are expected at the end of 2005 . CONCLUSIONS This study will help health care providers in future to make rational and informed choices about which components of a HF management program should be exp and ed and which components can possibly be deleted 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 and Research Objective : Heart failure ( HF ) patients experience frequent episodes of decompensation . While medication and behavior change play a major role in maintaining physiological stability , patient adherence to self-care recommendations is not optimal . The Theory of Heart Failure Self-care helped to underst and the concepts of self-care and chose a model of intervention . Conviction and confidence are central factors in facilitating self-care . Motivational interviewing ( MI ) , which aims to strengthen conviction and confidence , has been shown to improve self-care . In addition , the Transtheoretical Model , based on patients ' readiness to change , also has proven efficacy . The MI based on the stages of change ( MISC ) , a combination of MI and Transtheoretical Model , offers promise for improving self-care . The goal of this pilot study was to evaluate the preliminary effect of an MISC intervention on HF patients ' self-care behaviors . Subjects and Method : Thirty patients were recruited from an HF clinic and r and omly assigned to an experimental ( EG ) or control group ( n = 15/group ) . Patients from the EG received 3 interventions ( 1 in person , 2 on the phone ) . Data were collected at baseline and at 1 month after r and omization . The effect of the intervention was assessed on 5 self-care outcomes using analysis -of-covariance models . Results and Conclusion : Significant results were obtained regarding the confidence in performing self-care behaviors specific to HF ( P = .005 ) . Although the results of the other hypotheses were not statistically significant , for the majority , trends were in the expected direction in favor of the EG . The study suggests that an MISC intervention is useful to increase patients ' confidence in HF self-care and has potential to improve self-care . Further research is needed Background Self-management programs for patients with heart failure can reduce hospitalizations and mortality . However , no programs have analyzed their usefulness for patients with low literacy . We compared the efficacy of a heart failure self-management program design ed for patients with low literacy versus usual care .  Methods We performed a 12-month r and omized controlled trial . From November 2001 to April 2003 , we enrolled participants aged 30–80 , who had heart failure and took furosemide .  Intervention patients received education on self-care emphasizing daily weight measurement , diuretic dose self-adjustment , and symptom recognition and response . Picture-based educational material s , a digital scale , and scheduled telephone follow-up were provided to reinforce adherence . Control patients received a generic heart failure brochure and usual care . Primary outcomes were combined hospitalization or death , and heart failure-related quality of life . Results 123 patients ( 64 control , 59 intervention ) participated ; 41 % had inadequate literacy . Patients in the intervention group had a lower rate of hospitalization or death ( crude incidence rate ratio ( IRR ) = 0.69 ; CI 0.4 , 1.2 ; adjusted IRR = 0.53 ; CI 0.32 , 0.89 ) . This difference was larger for patients with low literacy ( IRR = 0.39 ; CI 0.16 , 0.91 ) than for higher literacy ( IRR = 0.56 ; CI 0.3 , 1.04 ) , but the interaction was not statistically significant . At 12 months , more patients in the intervention group reported monitoring weights daily ( 79 % vs. 29 % , p < 0.0001 ) . After adjusting for baseline demographic and treatment differences , we found no difference in heart failure-related quality of life at 12 months ( difference = -2 ; CI -5 , + 9 ) . Conclusion A primary care-based heart failure self-management program design ed for patients with low literacy
