    Input: Objective The aim of this study was to evaluate the impact of a home based intervention program ( HBIP ) on health related quality of life ( HRQoL )  after coronary artery bypass grafting ( CABG ) .  To strengthen the clinical interpretation , HRQoL data were compared to the general population . Methods In a r and omised controlled trial ( RCT ) , a total of 185 CABG patients ( 93 vs 92 ) completed the study . The intervention group received a HBIP 2 and 4 weeks after surgery .  HRQoL was measured by the Seattle Angina Question naire ( SAQ ) and the Short Form 36 ( SF-36 ) in both patient groups before surgery , at 6 weeks and 6 months after surgery . Results Significant improvements were found in both groups for the majority of subscales of HRQoL at 6-week and 6-month follow-up . However , these improvements did not differ significantly between the groups . Compared to the general population , significant differences ( P < 0.05 ) were found for the SF-36 subscales : role physical , role emotional and bodily pain . Conclusions HRQoL after CABG improved markedly over time , but no significant or clinical ly important differences were found when compared with controls . Thus , work to further develop and test the effect of a HBIP on HRQoL in patients undergoing rehabilitation following CABG is warranted Findings of systematic review s incorporating meta analysis are by nature hypothesis generating and should be carefully and judiciously interpreted . This need is epitomized by two of the largest review s of interventions to support risk factor reduction after a diagnosis of coronary heart disease ( Table 1 ) . These review s both included r and omized trials published in a similar timeframe ( up to 2003 or 2004 ) that compared the effects of various risk factor reduction programmes for patients with confirmed coronary heart disease to usual care . In 2004 , a Cochrane review found that supervised and unsupervised exercise-based cardiac rehabilitation provided to patients with different forms of coronary heart disease lowered all cause total mortality by 20 % and cardiac mortality by 26 % in 48 trials of 8940 patients . The review ers concluded that there was ‘ no difference in mortality effect between exercise-only cardiac rehabilitation and comprehensive cardiac rehabilitation , or by exercise dose or duration of followup ’ . Also , the exercise-based programmes did not reduce recurrent myocardial infa rct ion and the need for repeat coronary revascularization to statistically significant levels . Around the same time , a second review of 63 trials involving 21,295 patients who had undergone secondary cardiac prevention programmes found reductions of total mortality of 15 % and of acute myocardial infa rct ion of 17 % . However , in contrast to the previous review , the secondary prevention programmes significantly reduced the rate of recurrent heart attacks . Also , benefits did not differ between programmes ‘ that incorporated education and counselling about coronary risk factors with a supervised exercise programme , those that included risk factor education or counselling but no exercise component , and those that consisted of only a structured exercise programme ’ . On first reading , these review s appear to offer different conclusions on effects on cardiovascular morbidity and regarding the benefits of supervised exercise . Either could be cited selectively to support or refute the benefits of exercise programmes for morbidity or to support or refute the incorporation of supervised exercise into services . Why might these different conclusions have come about and how should they be interpreted ? Firstly , it is unlikely that the different conclusions arise from differences in quality as both review s were of high quality as defined by PRISMA criteria and included many of the same trials : 37 of the 48 ( 77 % ) exercise-based trials were included in the 63 ( 59 % ) secondary prevention trials . Rather , issues of statistical power can explain the differences noted in morbidity . The forest plot analyses showed that , although exercise-based programmes in the Cochrane review did not reach statistically significant headline ‘ effect sizes ’ , there was a tendency towards reduced recurrent myocardial infa rct ion and the need for repeat coronary revascularization . The larger review of secondary prevention programmes considered over twice the number of events in the analysis of recurrent myocardial infa rct ion and found that secondary prevention programmes significantly reduced the rate of recurrent heart attacks . Hence , focusing only on the presence or absence of Medicare beneficiaries in fee-for-service ( FFS ) who had chronic illnesses and volunteered to participate in 15 care coordination programs were r and omized to treatment or control status .  Nurses provided patient education ( mostly by telephone ) to improve adherence and ability to communicate with physicians . Patients were contacted an average of two times per month . The findings after 2 years are not encouraging . Few programs improved patient behaviors , health , or quality of care . The treatment group had significantly fewer hospitalizations in only one program ; no program reduced gross or net expenditures . However , effects may be observed when 4 years of followup are available and sample sizes increase AIMS In a multifactorial lifestyle behaviour programme , of 2 years duration , to study the maintenance of achieved behaviour and risk factor-related changes . METHODS AND RESULTS Out of a consecutive population of 151 patients treated with percutaneous transluminal angioplasty under 65 years of age , 87 were r and omly allocated to an intervention group ( n=46 ) or to a control group ( n=41 ) . The programme started with a 4 week residential stay , which was focused on health education and the achievement of  behaviour change .  During the first year of follow-up , a maintenance programme included regular contacts with a nurse , while no further rehabilitative efforts were offered during the second year . One patient died ( control ) . During the second year the proportion of hospitalized patients was lower in the intervention group ( 4 % vs 20%;P<0.05 ) . Patients in the intervention group improved several lifestyle dependent behaviours : diet ( index at 0 , 12 and 24 months ) : 10.5+/-3 . 4 , 12.9+/-2.5 and 12.4+/-2.6 in the intervention group ( I ) vs 10 . 1+/-3.2 , 10.7+/-3.0 and 11.8+/-3.2 in the control group (C);P<0.05 , exercise sessions per week : 2.5+/-2.3 , 4.5+/-1.9 and 4.4+/-2.1 ( I ) vs 3.1+/-2.2 , 3.5+/-2.3 and 3.7+/-2.7 (C);P<0.05 , and smoking ; 18 % , 6 % and 9 % ( I ) vs 12 % , 21 % and 18 % (C);P<0.05 . This corresponded to improvement in exercise capacity ( 0 , 12 and 24 months ) : 156+/-42 , 174+/-49 and 165+/-47 W ( I ) vs 164+/-40 , 163+/-49 and 156+/-48 watts (C);P<0.05 . There were no significant differences between the two groups with regard to serum cholesterol levels at 0 and 24 months : 5 . 4+/-0.8 and 5.2+/-0.9 mmol . l(-1)(I ) vs 5.4+/-1.0 and 4.9+/-0.9 mmol . l(-1)(C ) ; ns , low density lipoprotein cholesterol level : 3.6+/-0.8 and 3.4+/-0.8 mmol . l(-1)(I ) vs 3.7+/-0.9 and 3.3+/-0.7 mmol . l(-1)(C ) ; ns , triglyceride level : 2.2+/-1.6 and 1.8+/-1.3 mmol . l(-1)(I ) vs 2.2+/-1.4 and 1.6+/-0.6 mmol . l(-1)(C ) ; ns , body mass index ( 0 , 12 and 24 months ) : 27.5+/-4.5 , 27.0+/-4.3 and 27.4+/- 4.5 kg . m(-2)(I ) vs 26.8+/-2.8 , 26.9+/-2.7 and 26.9+/- 3.2 kg . m(-2)(C ) ; ns , waist/hip ratio or blood pressure . The two groups did not differ in quality of life , or psychological factors . Return to work after 12 and 24 months was 74 % and 78 % ( I ) vs 68 % and 61 % ( C ) ; ns . CONCLUSION This rehabilitation programme influenced important lifestyle behaviour and reduced some , but not all , important risk The LifeMasters Supported SelfCare demonstration program provides disease management ( DM ) services to Florida Medicare beneficiaries who are also enrolled in Medicaid and have congestive heart failure ( CHF ) , diabetes , or coronary artery disease ( CAD ) . The population -based program provides primarily telephonic patient education and monitoring services . Findings from the r and omized , intent-to-treat design over the first 18 months of operations show virtually no overall impacts on hospital or emergency room ( ER ) use , Medicare expenditures , quality of care , or prescription drug use for the 33,000 enrollees . However , for beneficiaries with CHF who resided in high-cost South Florida counties , the program reduced Medicare expenditures by 9.6 percent OBJECTIVES This study involving 570 women aged 60 years or older with heart disease , assessed the effects of a disease management program on physical functioning , symptom experience , and psychosocial status . METHODS Women were r and omly assigned to control or program groups . Six to eight women met weekly with a health educator and peer leader over 4 weeks to learn self-regulation skills with physical activity as the focus . Evaluative data were collected through telephone interviews , physical assessment s , and medical records at baseline and 4 and 12 months post baseline . RESULTS At 12 months , compared with controls , program women were less symptomatic ( p < .01 ) , scored better on the physical dimension of the Sickness Impact Profile ( SIP ; p < 0.05 ) , had improved ambulation as measured by the 6-minute walk ( p < 0.01 ) , and lost more body weight ( p < .001 ) . No differences related to psychosocial factors as measured by the SIP were noted . CONCLUSION A self-regulation-based program that was provided to older women with heart disease and that focused on physical activity and disease management problems salient to them , improved their physical functioning and symptom experience . Psychosocial benefit was not evident and may be a result of measurement error or due to insufficient program time spent on psychosocial aspects of functioning Abstract Objective : To assess the value of health education for patients with angina in reducing risk factors for cardiovascular disease and lessening the effect of angina on everyday activities . Design : R and omised controlled trial of personal health education given every four months . Setting : 18 general practice s in the greater Belfast area . Subjects : 688 patients aged less than 75 years and known to have had angina for at least six months ; 342 r and omised to receive education and 346 to no education .  Main outcome measures : Restriction of everyday activities , dietary habit , smoking habit , frequency of physical exercise ; blood pressure , body mass index , and serum total cholesterol concentration at entry to trial and after two years . Results : 317 in the intervention group and 300 in the control group completed the trial . At the two year review more of the intervention group ( 140 , 44 % ) reported taking daily physical exercise than the control group ( 70 , 24 % ) . The intervention group also reported eating a healthier diet than the control group and less restriction by angina in any everyday activity . No significant differences were found between the groups in smoking habit , systolic or diastolic blood pressure , cholesterol concentration , or body mass index . Conclusion : Despite having no significant effect on objective cardiovascular risk factors , personal health education of patients with angina seems to increase exercise and improve dietary habits and is effective in lessening the restriction of everyday activities Background Providing information is an important part of st and ard care and treatment for acute myocardial infa rct ion in patients . Evidence exists indicating that acute myocardial infa rct ion patients experience an information gap in the period immediately after discharge from the hospital . The aim of this study was to assess the short-term effects of a nurse-led telephone follow-up intervention to provide information and support to patients with acute myocardial infa rct ion after their discharge from hospital . Design and method A prospect i ve r and omized , controlled trial with a 6-month follow-up was conducted . A total of 288 patients were allocated to either an intervention group ( n = 156 ) or a control group ( n = 132 ) . The latter received routine post-discharge care . The primary endpoint measured at 3 and 6 months after discharge was the health-related quality of life using the 36-item Short Form Health Survey . Secondary endpoints included smoking and exercise habits . Results In both groups , health-related quality of life improved significantly over time on most subscales . A statistically significant difference in favour of the intervention group was found on the 36-item Short Form Health Survey Physical Health Component Summary Scale ( P=0.034 ) after 6 months . No difference was found between the groups on the Mental Health Component Summary Scale . We found a significant difference with respect to frequency of physical activity in favour of the intervention group after 6 months ( P=0.004 ) . More participants in the intervention group than the control group had ceased smoking at the 6-month follow-up ( P=0.055 ) . Conclusion A nurse-led systematic telephone follow-up intervention significantly improved the physical dimension of health-related quality of life in patients in the intervention group compared with usual care patients .

There was evidence to suggest that education can improve HRQoL and decrease healthcare costs by reductions in downstream healthcare utilization .
Conclusions : Our review had insufficient power to exclude clinical ly important effects of education on mortality and morbidity .
