Tracking Cardiac Rehabilitation Utilization in Medicare Beneficiaries: 2017 UPDATE.

PURPOSE: This study updates cardiac rehabilitation (CR) utilization data in a cohort of Medicare beneficiaries hospitalized for CR-eligible events in 2017, including stratification by select patient demographics and state of residence. METHODS: We identified Medicare fee-for-service beneficiaries who experienced a CR-eligible event and assessed their CR participation (≥1 CR sessions in 365 d), engagement, and completion (≥36 sessions) rates through September 7, 2019. Measures were assessed overall, by beneficiary characteristics and state of residence, and by primary (myocardial infarction; coronary artery bypass surgery; heart valve repair/replacement; percutaneous coronary intervention; or heart/heart-lung transplant) and secondary (angina; heart failure) qualifying event type. RESULTS: In 2017, 412 080 Medicare beneficiaries had a primary CR-eligible event and 28.6% completed ≥1 session of CR within 365 d after discharge from a qualifying event. Among beneficiaries who completed ≥1 CR session, the mean total number of sessions was 25 ± 12 and 27.6% completed ≥36 sessions. Nebraska had the highest enrollment rate (56.1%), with four other states also achieving an enrollment rate >50% and 23 states falling below the overall rate for the United States. CONCLUSIONS: The absolute enrollment, engagement, and program completion rates remain low among Medicare beneficiaries, indicating that many patients did not benefit or fully benefit from a class I guideline-recommended therapy. Additional research and continued widespread adoption of successful enrollment and engagement initiatives are needed, especially among identified populations.

Traditional vs Extended Hybrid Cardiac Rehabilitation Based on the Continuous Care Model for Patients Who Have Undergone Coronary Artery Bypass Surgery in a Middle-Income Country: A Randomized Controlled Trial.

OBJECTIVE: To compare traditional (1-month supervised) vs hybrid cardiac rehabilitation (CR; usual care) with an additional 3 months offered remotely based on the continuous care model (intervention) in patients who have undergone coronary artery bypass graft (CABG). DESIGN: Randomized controlled trial, with blinded outcome assessment. SETTING: A major heart center in a middle-income country. PARTICIPANTS: Of 107 eligible patients who were referred to CR during the period of study, 82.2% (N=88) were enrolled (target sample size). Participants were randomly assigned 1:1 (concealed; 44 per parallel arm). There was 92.0% retention. INTERVENTIONS: After CR, participants were given a mobile application and communicated biweekly with the nurse from months 1-4 to control risk factors. MAIN OUTCOME MEASURES: Quality of life (QOL, Short Form-36, primary outcome); functional capacity (treadmill test); and the Depression, Anxiety and Stress Scale were evaluated pre-CR, after 1 month, and 3 months after CR (end of intervention), as well as rehospitalization. RESULTS: The analysis of variance interaction effects for the physical and mental component summary scores of QOL were <.001, favoring intervention (per protocol); there were also significant increases from pre-CR to 1 month, and from 1 month to the final assessment in the intervention arm (P<.001), with change in the control arm only to 1 month. The effect sizes were 0.115 and 0.248, respectively. Similarly, the interaction effect for functional capacity was significant (P<.001), with a clinically significant 1.5 metabolic equivalent of task increase in the intervention arm. There were trends for group effects for the psychosocial indicators, with paired t tests revealing significant increases in each at both assessment points in the intervention arm. At 4 months, there were 4 (10.3%) rehospitalizations in the control arm and none in intervention (P=.049). Intended theoretical mechanisms were also affected by the intervention. CONCLUSIONS: Extending CR in this accessible manner, rendering it more comprehensive, was effective in improving outcomes.

The challenge of non-adherence to early rehabilitation after coronary artery bypass surgery: Secondary results from the SheppHeartCABG trial.

BACKGROUND: Attending and maintaining a cardiac rehabilitation programme is a challenge. AIMS: The purpose of this study was to explore associations between non-adherence to early coronary artery bypass graft rehabilitation and sociodemographic and clinical baseline data. METHODS: Coronary artery bypass graft patients were randomised 1:1 to either four weeks of comprehensive early rehabilitation or usual care. Outcomes were assessed at three time-points points: baseline, discharge and four weeks post-coronary artery bypass graft. Differences in sociodemographic and clinical baseline data in adherent versus non-adherent patients were tested using the Pearson χ2 test for categorical variables. To test associations between non-adherence to exercise training and sociodemographic and clinical baseline data, multivariate logistic regression was used to estimate the odds ratio for in-hospital training and post-discharge training adjusted for age, sex and left ventricular ejection fraction. RESULTS: Non-adherence to in-hospital versus post-discharge exercise training was 31% (n=48) versus 53% (n=81). Female non-adherence was 20% versus 70%. Non-adherence to in-hospital versus post-discharge mindfulness was 87% versus 70%. Male non-adherence to mindfulness was 85% versus 70%. Non-adherence to psycho-educational consultations was 3%, most of whom were men. Patients with university level education were more adherent to in-hospital exercise training than patients with lower educational level (odds ratio=3.14 (95% confidence interval; 1.16-8.51), p=0.02). Diabetic patients were more non-adherent to exercise training after discharge (3.74 (1.54-9.08), p=0.004) as were overweight patients (0.37 (0.17-0.80), p=0.01). CONCLUSIONS: This study demonstrated wide acceptance of psycho-educational consultations in post-coronary artery bypass graft patients. Adherence to physical rehabilitation was low especially after discharge from hospital and the opportunity to attend a mindfulness programme was not used.

Financial Incentives to Increase Cardiac Rehabilitation Participation Among Low-Socioeconomic Status Patients: A Randomized Clinical Trial.

OBJECTIVES: This study sought to examine the efficacy of financial incentives to increase Medicaid patient participation in and completion of cardiac rehabilitation (CR). BACKGROUND: Participation in CR reduces morbidity, mortality, and hospitalizations while improving quality of life. Lower-socioeconomic status (SES) patients are much less likely to attend and complete CR, despite being at increased risk for recurrent cardiovascular events. METHODS: A total of 130 individuals enrolled in Medicaid with a CR-qualifying cardiac event were randomized 1:1 to receive financial incentives on an escalating schedule ($4 to $50) for completing CR sessions or to receive usual care. Primary outcomes were CR participation (number of sessions completed) and completion (≥30 sessions completed). Secondary outcomes included changes in sociocognitive measurements (depressive/anxious symptoms, executive function), body composition (waist circumference, body mass index), fitness (peak VO2) over 4 months, and combined number of hospitalizations and emergency department (ED) contacts over 1 year. RESULTS: Patients randomized to the incentive condition completed more sessions (22.4 vs. 14.7, respectively; p = 0.013) and were almost twice as likely to complete CR (55.4% vs. 29.2%, respectively; p = 0.002) as controls. Incentivized patients were also more likely to experience improvements in executive function (p < 0.001), although there were no significant effects on other secondary outcomes. Patients who completed ≥30 sessions had 47% fewer combined hospitalizations and ED visits (p = 0.014), as reflected by a nonsignificant trend by study condition with 39% fewer hospital contacts in the incentive condition group (p = 0.079). CONCLUSIONS: Financial incentives improve CR participation among lower-SES patients following a cardiac event. Increasing participation among lower-SES patients in CR is critical for positive longer-term health outcomes. (Increasing Cardiac Rehabilitation Participation Among Medicaid Enrollees; NCT02172820).

Assessment of Physical Activity by Wearable Technology During Rehabilitation After Cardiac Surgery: Explorative Prospective Monocentric Observational Cohort Study.

BACKGROUND: Wearable technology is finding its way into clinical practice. Physical activity describes patients' functional status after cardiac surgery and can be monitored remotely by using dedicated trackers. OBJECTIVE: The aim of this study was to compare the progress of physical activity in cardiac rehabilitation by using wearable fitness trackers in patients undergoing coronary artery bypass surgery by either the conventional off-pump coronary artery bypass (OPCAB) or the robotically assisted minimally invasive coronary artery bypass (RA-MIDCAB). We hypothesized faster recovery of physical activity after RA-MIDCAB in the first weeks after discharge as compared to OPCAB. METHODS: Patients undergoing RA-MIDCAB or OPCAB were included in the study. Each patient received a Fitbit Charge HR (Fitbit Inc, San Francisco, CA) physical activity tracker following discharge. Rehabilitation progress was assessed by measuring the number of steps and physical activity level daily. The physical activity level was calculated as energy expenditure divided by the basic metabolic rate. RESULTS: A total of 10 RA-MIDCAB patients with a median age of 68 (min, 55; max, 83) years and 12 OPCAB patients with a median age of 69 (min, 50; max, 82) years were included. Baseline characteristics were comparable except for body mass index (RA-MIDCAB: 26 kg/m²; min, 22; max, 28 versus OPCAB: 29 kg/m²; min, 27; max, 33; P<.001). Intubation time (P<.05) was significantly lower in the RA-MIDCAB group. A clear trend, although not statistically significant, was observed towards a higher number of steps in RA-MIDCAB patients in the first week following discharge. CONCLUSIONS: RA-MIDCAB patients have an advantage in recovery in the first weeks of revalidation, which is reflected by the number of steps and physical activity level measured by the Fitbit Charge HR, as compared to OPCAB patients. However, unsupervised assessment of daily physical activity varied widely and could have consequences with regard to the use of these trackers as research tools.

Interventions to promote patient utilisation of cardiac rehabilitation.

BACKGROUND: International clinical practice guidelines routinely recommend that cardiac patients participate in rehabilitation programmes for comprehensive secondary prevention. However, data show that only a small proportion of these patients utilise rehabilitation. OBJECTIVES: First, to assess interventions provided to increase patient enrolment in, adherence to, and completion of cardiac rehabilitation. Second, to assess intervention costs and associated harms, as well as interventions intended to promote equitable CR utilisation in vulnerable patient subpopulations. SEARCH METHODS: Review authors performed a search on 10 July 2018, to identify studies published since publication of the previous systematic review. We searched the Cochrane Central Register of Controlled Trials (CENTRAL); the National Health Service (NHS) Centre for Reviews and Dissemination (CRD) databases (Health Technology Assessment (HTA) and Database of Abstracts of Reviews of Effects (DARE)), in the Cochrane Library (Wiley); MEDLINE (Ovid); Embase (Elsevier); the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (EBSCOhost); and Conference Proceedings Citation Index - Science (CPCI-S) on Web of Science (Clarivate Analytics). We checked the reference lists of relevant systematic reviews for additional studies and also searched two clinical trial registers. We applied no language restrictions. SELECTION CRITERIA: We included randomised controlled trials (RCTs) in adults with myocardial infarction, with angina, undergoing coronary artery bypass graft surgery or percutaneous coronary intervention, or with heart failure who were eligible for cardiac rehabilitation. Interventions had to aim to increase utilisation of comprehensive phase II cardiac rehabilitation. We included only studies that measured one or more of our primary outcomes. Secondary outcomes were harms and costs, and we focused on equity. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the titles and abstracts of all identified references for eligibility, and we obtained full papers of potentially relevant trials. Two review authors independently considered these trials for inclusion, assessed included studies for risk of bias, and extracted trial data independently. We resolved disagreements through consultation with a third review author. We performed random-effects meta-regression for each outcome and explored prespecified study characteristics. MAIN RESULTS: Overall, we included 26 studies with 5299 participants (29 comparisons). Participants were primarily male (64.2%). Ten (38.5%) studies included patients with heart failure. We assessed most studies as having low or unclear risk of bias. Sixteen studies (3164 participants) reported interventions to improve enrolment in cardiac rehabilitation, 11 studies (2319 participants) reported interventions to improve adherence to cardiac rehabilitation, and seven studies (1567 participants) reported interventions to increase programme completion. Researchers tested a variety of interventions to increase utilisation of cardiac rehabilitation. In many studies, this consisted of contacts made by a healthcare provider during or shortly after an acute care hospitalisation.Low-quality evidence shows an effect of interventions on increasing programme enrolment (19 comparisons; risk ratio (RR) 1.27, 95% confidence interval (CI) 1.13 to 1.42). Meta-regression revealed that the intervention deliverer (nurse or allied healthcare provider; P = 0.02) and the delivery format (face-to-face; P = 0.01) were influential in increasing enrolment. Low-quality evidence shows interventions to increase adherence were effective (nine comparisons; standardised mean difference (SMD) 0.38, 95% CI 0.20 to 0.55), particularly when they were delivered remotely, such as in home-based programs (SMD 0.56, 95% CI 0.37 to 0.76). Moderate-quality evidence shows interventions to increase programme completion were also effective (eight comparisons; RR 1.13, 95% CI 1.02 to 1.25), but those applied in multi-centre studies were less effective than those given in single-centre studies, leading to questions regarding generalisability. A moderate level of statistical heterogeneity across intervention studies reflects heterogeneity in intervention approaches. There was no evidence of small-study bias for enrolment (insufficient studies to test for this in the other outcomes).With regard to secondary outcomes, no studies reported on harms associated with the interventions. Only two studies reported costs. In terms of equity, trialists tested interventions designed to improve utilisation among women and older patients. Evidence is insufficient for quantitative assessment of whether women-tailored programmes were associated with increased utilisation, and studies that assess motivating women are needed. For older participants, again while quantitative assessment could not be undertaken, peer navigation may improve enrolment. AUTHORS' CONCLUSIONS: Interventions may increase cardiac rehabilitation enrolment, adherence and completion; however the quality of evidence was low to moderate due to heterogeneity of the interventions used, among other factors. Effects on enrolment were larger in studies targeting healthcare providers, training nurses, or allied healthcare providers to intervene face-to-face; effects on adherence were larger in studies that tested remote interventions. More research is needed, particularly to discover the best ways to increase programme completion.

Cardiac rehabilitation for patients having cardiac surgery: a systematic review.

INTRODUCTION: Cardiac rehabilitation (CR) is recommended for all cardiac patients including patients after cardiac surgery. Since the effect of CR after cardiac surgery has not been well established yet, we conducted a systematic review on the effects of CR for patients after cardiac surgery compared to treatment as usual. EVIDENCE ACQUISITION: A systematic review of randomized clinical trials (RCTs), quasi-randomized and prospective observational studies in The Cochrane Library, PubMed/MEDLINE and EMBASE was undertaken until October 18th, 2017. Adults after any kind of cardiac surgery were included. Primary outcome was all-cause mortality, other outcomes were serious adverse events, health-related quality of life, work participation, functioning and costs/cost-effectiveness. Risk of bias was evaluated, and the quality of evidence was assessed by the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) criteria. EVIDENCE SYNTHESIS: Eighteen RCTs and 15 observational studies were included. Low risk of bias was only observed in one observational study. Meta-analysis of RCTs suggested no significant difference of CR compared to control on mortality (random-effects relative risk (RR) 0.93 (95% CI: 0.40-1.81), while observational studies suggested statistically significant beneficial effect associated with CR (random-effects RR=0.49, 95% CI: 0.35 - 0.68). CR did not significantly affect any of the other outcomes. Due to the limited data TSA could not be performed. CONCLUSIONS: The body of evidence does not allow us to reach any reliable conclusions about the effectiveness of CR following cardiac surgery. Future trials need to be conducted with low risks of bias and clearly defined outcomes.

Referral to Cardiac Rehabilitation After Percutaneous Coronary Intervention, Coronary Artery Bypass Surgery, and Valve Surgery: Data From the Clinical Outcomes Assessment Program.

BACKGROUND: Despite guideline recommendations that patients undergoing percutaneous coronary intervention (PCI), coronary artery bypass surgery, or valve surgery be referred to cardiac rehabilitation, cardiac rehabilitation is underused. The objective of this study was to examine hospital-level variation in cardiac rehabilitation referral after PCI, coronary artery bypass surgery, and valve surgery. METHODS AND RESULTS: We analyzed data from the Clinical Outcomes Assessment Program, a registry of all nonfederal hospitals performing PCI and cardiac surgery in Washington State. We included eligible PCI, coronary artery bypass surgery, and valve surgery patients from 2010 to 2015. We analyzed PCI and cardiac surgery separately by performing multivariable hierarchical logistic regression for the outcome of cardiac rehabilitation referral at discharge, clustered by hospital. Patient-level covariates included age, sex, race/ethnicity, comorbidities, and procedure indication/status. Cardiac rehabilitation referral was reported in 48% (34 047/71 556) of PCI patients and 91% (21 831/23 972) of cardiac surgery patients. The hospital performing the procedure was a stronger predictor of referral than any individual patient characteristic for PCI (hospital referral range 3%-97%; median odds ratio, 5.94; 95% confidence interval, 4.10-9.49) and cardiac surgery (range 54%-100%; median odds ratio, 7.09; 95% confidence interval, 3.79-17.80). Hospitals having an outpatient cardiac rehabilitation program explained only 10% of PCI variation and 0% of cardiac surgery variation. CONCLUSIONS: Cardiac rehabilitation referral at discharge was less prevalent after PCI than cardiac surgery. The strongest predictor of cardiac rehabilitation referral was the hospital performing the procedure. Efforts to improve cardiac rehabilitation referral should focus on increasing referral after PCI, especially in low referral hospitals.

Medicare Program; Advancing Care Coordination Through Episode Payment Models (EPMs); Cardiac Rehabilitation Incentive Payment Model; and Changes to the Comprehensive Care for Joint Replacement Model (CJR). Final rule.

This final rule implements three new Medicare Parts A and B episode payment models, a Cardiac Rehabilitation (CR) Incentive Payment model and modifications to the existing Comprehensive Care for Joint Replacement model under section 1115A of the Social Security Act. Acute care hospitals in certain selected geographic areas will participate in retrospective episode payment models targeting care for Medicare fee-forservice beneficiaries receiving services during acute myocardial infarction, coronary artery bypass graft, and surgical hip/femur fracture treatment episodes. All related care within 90 days of hospital discharge will be included in the episode of care. We believe these models will further our goals of improving the efficiency and quality of care for Medicare beneficiaries receiving care for these common clinical conditions and procedures.

Predictors of early return to work after a coronary artery bypass graft surgery (CABG).

OBJECTIVES: Identifying factors predictive of early return to work in patients who underwent a coronary artery bypass graft surgery (CABG). MATERIAL AND METHODS: Two hundred twenty-six working patients who volunteered and underwent a primary coronary artery bypass surgery between September 2013 and May 2014 were selected for the study and followed up for 6 months. Predictors of early return to work (RTW) (within 2 months) were analyzed from variables in a prospectively collected database and the 36-Item Short Form Health Survey (SF-36) questionnaire carried out in the hospital and rehabilitation center as well as from the follow-up performed via the phone. RESULTS: One hundred and two (45.1%) and 155 (68.9%) patients returned to work within 2 and 3 months after the surgery, respectively. Furthermore, 196 patients (87.1%) returned to work within 6 months after the surgery. In the univariate analysis, demographic or socioeconomic factors (such as age, level of education, income), occupational factors (such as occupation type, working hours per week, duration of the preoperative absence from work), psychological factors (such as a patient's concern about adverse health effects of RTW, feeling depressed, a patient's attitude towards his/her ability to RTW and a patient's perception of his/her job stress level) and medical factors (such as serum troponin T and creatine kinase MB (CKMB) level, pump time in surgery, co-surgery and dyslipidemia history) had a statistically significant correlation with early return to work. The patients who early returned to work had significantly higher scores in 3 domains on the SF-36 questionnaire (used for assessing the patients' quality of life), compared to those who did not return to work early (including physical functioning, role limitations due to physical health and pain). CONCLUSIONS: In the present study we identified 4 new medical factors that could be used as predictors of early return to work after CABG. These factors are: normal serum troponin T level, shorter pump time in surgery, normal mean arterial pressure (MAP) before the surgery and higher serum magnesium (Mg) levels.

Cardiac Rehabilitation: Improving Function and Reducing Risk.

Cardiac rehabilitation is a comprehensive multidisciplinary program individually tailored to the needs of patients with cardiovascular disease. The overall goals focus on improving daily function and reducing cardiovascular risk factors. Cardiac rehabilitation includes interventions aimed at lowering blood pressure and improving lipid and diabetes mellitus control, with tobacco cessation, behavioral counseling, and graded physical activity. The physical activity component typically involves 36 sessions over 12 weeks, during which patients participate in supervised exercise under cardiac monitoring. There are also intensive programs that include up to 72 sessions lasting up to 18 weeks, although these programs are not widely available. Additional components of cardiac rehabilitation include counseling on nutrition, screening for and managing depression, and assuring up-to-date immunizations. Cardiac rehabilitation is covered by Medicare and recommended for patients following myocardial infarction, bypass surgery, and stent placement, and for patients with heart failure, stable angina, and several other conditions. Despite proven benefits in mortality rates, depression, functional capacity, and medication adherence, rates of referral for cardiac rehabilitation are suboptimal. Groups less likely to be referred are older adults, women, patients who do not speak English, and persons living in areas where cardiac rehabilitation is not locally available. Additionally, primary care physicians refer patients less often than cardiologists and cardiothoracic surgeons.

On occupational fitness examination of workers exposed to occupational hazards after coronary artery bypass grafting.

Myocardium revascularization in coronary heart disease patients is one of the most important treatment modalities. Considerable improvement of somatic state after surgery for IHD is seen in 82-83% of patients in average, whereas only hardly more than a half return to occupational activity without decrease in preoperative level of qualification and performance. In occupational therapy and industrial medicine clinic with FBSI <>, examination covered 68 workers of Perm' area enterprises, derected for occupational fitness study after coronary artery bypass grafting and 100 workers at various terms after myocardium infarction, with verified IHD. Risk factors evaluation demonstrated that after coronary artery bypass grafting 75% of patients are motivated to maintain healthy lifestyle and compliance to treatment over 5 years; positive changes in a year according to functional study were seen in 75% of cases; level of blood pressure in office 127.8±9.4 mm Hg; dyslipidemia, hypercholesterolemia remain in 11.7% of cases. At first stage, criteria of permit-to-work are: decrease in functional class of chronic cardiac failure to 0-II degrees from initial one; absence of exertional stenocardia or exertional stenocardia less than II degree, absence of ventricular arrhythmias of high grade.

Statin use following hospitalization among Medicare beneficiaries with a secondary discharge diagnosis of acute myocardial infarction.

BACKGROUND: Patients with coronary heart disease are recommended to use statins following hospital discharge. Acute myocardial infarction (AMI) is a common complication of hospitalization, but the use of statins following discharge among patients who were not initially hospitalized for AMI has not been assessed adequately. METHODS AND RESULTS: Using the Medicare 5% national random sample, we determined statin use among beneficiaries who were hospitalized and who had a secondary discharge diagnosis of AMI and among beneficiaries who had a primary discharge diagnosis of AMI, coronary artery bypass grafting, or percutaneous coronary intervention in 2007-2009. Statin use was defined by a pharmacy (Medicare Part D) claim within 90 days following discharge. Of 8175 Medicare beneficiaries who did not take statins prior to hospitalization, 31.2% with AMI as a secondary discharge diagnosis, 60.5% with AMI as the primary discharge diagnosis, 67.6% with coronary artery bypass grafting, and 63.9% with a percutaneous coronary intervention initiated statins. After multivariable adjustment, the risk ratio for statin initiation comparing beneficiaries with a secondary versus primary discharge diagnosis of AMI was 0.59 (95% CI 0.54 to 0.65). Among 5468 Medicare beneficiaries taking statins prior to hospitalization, statin use following discharge was lower for those with AMI as a secondary discharge diagnosis (71.8%) compared with their counterparts with AMI, coronary artery bypass grafting, and percutaneous coronary intervention (84.1%, 83.8%, and 87.3%, respectively) as the primary discharge diagnosis. CONCLUSION: Medicare beneficiaries with a secondary hospital discharge diagnosis of AMI were less likely to fill statins compared with those with other coronary heart disease events.

Hospital-based versus hybrid cardiac rehabilitation program in coronary bypass surgery patients in western Iran: effects on exercise capacity, risk factors, psychological factors, and quality of life.

PURPOSE: The efficacy of alternative delivery models for a cardiac rehabilitation program (CRP) in low- and middle-income countries is not well documented. This study compared the traditional hospital-based CRP with a hybrid CRP in western Iran. METHODS: This observational study was conducted with postcoronary surgery patients in Imam-Ali Hospital in Kermanshah, Iran. Both program models included 2 phases: (1) a common preliminary phase (2-4 weeks) involving exercise training and a plan to control cardiac risk factors; and (2) a complementary phase (8 weeks) consisting of group educational classes and exercise training conducted 3 times a week in the hospital or once a week accompanied by phone calls in the hybrid program. Changes in exercise capacity, blood pressure, lipids, resting heart rate, body mass index, waist circumference, smoking, depression, anxiety, and quality of life as well as differences in attendance at hospital sessions were investigated. RESULTS: From a total of 887 patients, 780 (87.9%) completed the programs. There was no association between course completion and type of CRP. Mean age of patients completing the programs was 55.6 ± 8.7 years and 23.8% were female. The hospital-based (n = 585) and hybrid (n = 195) programs resulted in a significant increase in exercise capacity (P < .001 for both). Additional improvements in other outcomes were noted and attendance rates were similar in both CRPs. CONCLUSIONS: A well-designed hybrid CRP can be a viable alternative for hospital-based CRP in low- and middle-income countries where there are no appropriate health facilities in remote areas.

Promoting patient uptake and adherence in cardiac rehabilitation.

BACKGROUND: Cardiac rehabilitation is an important component of recovery from coronary events but uptake and adherence to such programs are below recommended levels. In 2010, our Cochrane review identified some evidence that interventions to increase uptake of cardiac rehabilitation can be effective but there was insufficient evidence to provide recommendations on intervention to increase adherence. In this review, we update the previously published Cochrane review. OBJECTIVES: To determine the effects, both harms and benefits, of interventions to increase patient uptake of, or adherence to, cardiac rehabilitation. SEARCH METHODS: We performed an updated search in January 2013 to identify studies published after publication of the previous systematic review. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 12, 2012), MEDLINE (Ovid), EMBASE (Ovid), CINAHL EBSCO, Conference Proceedings Citation Index - Science (CPCI-S) on Web of Science (Thomson Reuters), and National Health Service (NHS) Centre for Reviews and Dissemination (CRD) databases (Health Technology Assessment (HTA) and Database of Abstracts of Reviews of Effects (DARE)) on The Cochrane Library (Issue 4, 2012). We also checked reference lists of identified systematic reviews and randomised controlled trials (RCTs) for additional studies. We applied no language restrictions. SELECTION CRITERIA: Adults with myocardial infarction, coronary artery bypass graft, percutaneous transluminal coronary angioplasty, heart failure, angina, or coronary heart disease eligible for cardiac rehabilitation and RCTs or quasi-randomized trials of interventions to increase uptake or adherence to cardiac rehabilitation or any of its component parts. We only included studies reporting a primary outcome. DATA COLLECTION AND ANALYSIS: At least three authors independently screened titles and abstracts of all identified references for eligibility and obtained full papers of potentially relevant trials. At least two authors checked the selection. Three authors assessed included studies for risk of bias. MAIN RESULTS: The updated search identified seven new studies (880 participants) of interventions to improve uptake of cardiac rehabilitation and one new study (260 participants) of interventions to increase adherence. When added to the previous version of this review, we included 18 studies (2505 participants), 10 studies (1338 participants) of interventions to improve uptake of cardiac rehabilitation and eight studies (1167 participants) of interventions to increase adherence. We assessed the majority of studies as having high or unclear risk of bias. Meta-analysis was not possible due to multiple sources of heterogeneity. Eight of 10 studies demonstrated increased uptake of cardiac rehabilitation. Successful interventions to improve uptake of cardiac rehabilitation included: structured nurse- or therapist-led contacts, early appointments after discharge, motivational letters, gender-specific programs, and intermediate phase programs for older patients. Three of eight studies demonstrated improvement in adherence to cardiac rehabilitation. Successful interventions included: self monitoring of activity, action planning, and tailored counselling by cardiac rehabilitation staff. Data were limited on mortality and morbidity but did not demonstrate a difference in cardiovascular events or mortality except for one study that noted an increased rate of revascularization in the intervention group. None of the studies found a difference in health-related quality of life and there was no evidence of adverse events. No studies reported on costs or healthcare utilization. AUTHORS' CONCLUSIONS: We found only weak evidence to suggest that interventions to increase the uptake of cardiac rehabilitation are effective. Practice recommendations for increasing adherence to cardiac rehabilitation cannot be made. Interventions targeting patient-identified barriers may increase the likelihood of success. Further high-quality research is still needed. 

Effectiveness of inpatient and outpatient strategies in increasing referral and utilization of cardiac rehabilitation: a prospective, multi-site study.

BACKGROUND: Despite the evidence of benefit, cardiac rehabilitation (CR) remains highly underutilized. The present study examined the effect of two inpatient and one outpatient strategy on CR utilization: allied healthcare provider completion of referral (a policy that had been endorsed and approved by the cardiac program leadership in advance; PRE-APPROVED); CR intake appointment booked before hospital discharge (PRE-BOOKED); and early outpatient education provided at the CR program shortly after inpatient discharge (EARLY ED).In this prospective observational study, 2,635 stable cardiac inpatients from 11 Ontario hospitals completed a sociodemographic survey, and clinical data were extracted from charts. One year later, participants were a mailed survey that assessed CR use. Participating inpatient units and CR programs to which patients were referred were coded to reflect whether each of the strategies was used (yes/no). The effect of each strategy on participants' CR referral and enrollment was examined using generalized estimating equations. RESULTS: A total of 1,809 participants completed the post-test survey. Adjusted analyses revealed that the implementation of one of the inpatient strategies was significantly related to greater referral and enrollment (PRE-APPROVED: OR = 1.96, 95%CI = 1.26 to 3.05, and OR = 2.91, 95%CI = 2.20 to 3.85, respectively). EARLY ED also resulted in significantly greater enrollment (OR = 4.85, 95%CI = 2.96 to 7.95). CONCLUSIONS: These readily-implementable strategies could significantly increase access to and enrollment in CR for the cardiac population. The impact of these strategies on wait times warrants exploration.

Recent Trends in Adherence to Secondary Prevention Guidelines for Patients Undergoing Coronary Revascularization in Washington State: An Analysis of the Clinical Outcomes Assessment Program (COAP) Registry.

BACKGROUND: Previous studies indicated that patients undergoing coronary artery bypass graft (CABG) surgery are less likely to receive guideline-based secondary prevention therapy than are those undergoing percutaneous coronary intervention (PCI) after an acute myocardial infarction. We aimed to evaluate whether these differences have persisted after the implementation of public reporting of hospital metrics. METHODS AND RESULTS: The Clinical Outcomes Assessment Program (COAP) database was analyzed retrospectively to evaluate adherence to secondary prevention guidelines at discharge in patients who underwent coronary revascularization after an acute ST-elevation myocardial infarction in Washington State. From 2004 to 2007, 9260 patients received PCI and 692 underwent CABG for this indication. Measures evaluated included prescription of aspirin, ß-blockers, angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers, or lipid-lowering medications; cardiac rehabilitation referral; and smoking-cessation counseling. Composite adherence was lower for CABG than for PCI patients during the period studied (79.6% versus 89.7%, P<0.01). Compared to patients who underwent CABG, patients who underwent PCI were more likely to receive each of the pharmacological therapies. There was no statistical difference in smoking-cessation counseling (91.7% versus 90.3%, P=0.63), and CABG patients were more likely to receive referral for cardiac rehabilitation (70.9% versus 48.3%, P<0.01). Adherence rates improved over time among both groups, with no significant difference in composite adherence in 2006 (85.6% versus 87.6%, P=0.36). CONCLUSIONS: Rates of guideline-based secondary prevention adherence in patients with ST-elevation myocardial infarction who underwent CABG surgery have been improving steadily in Washington State. The improvement possibly is associated with the implementation of public reporting of quality measures.

Avaliação da ventilação não-invasiva com dois níveis de pressão positiva nas vias aéreas após cirurgia cardíaca / Assessment of noninvasive ventilation with two levels of positive airway pressure in patients after cardiac surgery

INTRODUÇÃO: A aplicação de ventilação por dois níveis de pressão positiva (BiPAP®) associada à fisioterapia respiratória convencional (FRC) no pós-operatório (PO) imediato de cirurgia cardíaca pode contribuir para a diminuição das complicações pulmonares. OBJETIVO: Avaliar a segurança e a adesão da aplicação preventiva do BiPAP® associado a FRC no PO imediato de revascularização do miocárdio. MÉTODOS: Vinte e seis pacientes submetidos a revascularização do miocárdio foram aleatoriamente alocados. O Grupo Controle (GC) foi tratado com FRC, o Grupo BiPAP (GB) foi submetido a 30 minutos de BiPAP®, duas vezes ao dia, associado à FRC. A FRC foi realizada em ambos os grupos, duas vezes ao dia. Todos os pacientes foram avaliados quanto: capacidade vital, permeabilidade das vias aéreas, pressões respiratórias máximas, saturação de oxigênio, frequência cardíaca, frequência respiratória, volume minuto, volume corrente, pressões arteriais sistólica e diastólica. As avaliações foram realizadas durante a internação no pré-operatório, imediatamente após a extubação, e na 24ª e 48ª horas após extubação. RESULTADOS: No GC, 61,5 por cento dos pacientes tiveram algum grau de atelectasias, no GB, 54 por cento (P=0,691). A capacidade vital foi estatisticamente maior no GB no PO (P<0,015). Todos os outros parâmetros de ventilometria, gasometria, manovacuometria e hemodinâmicos foram semelhantes entre os grupos. CONCLUSÃO: A cirurgia de revascularização do miocárdio leva à degradação da função respiratória no PO, e a aplicação da ventilação com pressão positiva (BiPAP®) pode ser benéfica para reestabelecer a função pulmonar mais rapidamente, principalmente a capacidade vital, de forma segura, sendo bem aceita pelos paciente, devido ao maior conforto em relação à sensação de dor durante a execução da fisioterapia respiratória.

INTRODUCTION: The application of two levels of ventilation by positive pressure (BiPAP®) associated with conventional respiratory therapy (CRT) in postoperative periord of cardiac surgery may contribute to reduction of pulmonary complications. OBJECTIVES: To evaluate the safety and compliance of preventive application of BiPAP® CRT associated with immediate postoperative myocardial revascularization. METHODS: 26 patients undergoing coronary artery bypass grafting were randomly allocated in one of the groups. Patients of the Control Group (CG) were treated only with conventional respiratory therapy, compared to BiPAP group (BG) (in addition to conventional respiratory therapy the patients were subjected to 30 minutes of ventilation by two levels twice a day). The conventional respiratory therapy was held in both groups, twice a day. All patients were evaluated for vital capacity, airway permeability, maximal respiratory pressures, oxygen saturation, heart rate, respiratory frequency, Volume Minute, tidal volume, systolic and diastolic blood pressure. Evaluations were performed during hospitalization preoperatively, immediately after extubation, 24h and 48h after extubation. RESULTS: In CG 61.5 percent of patients had some degree of atelectasias, in comparison to 54 percent of BG (P=0.691). The vital capacity was higher in the GB postoperatively (P<0.015). All the other ventilometric, gasometric, hemodynamic and manometric parameters were similar between groups. CONCLUSION: Coronary artery bypass grafting leads to deterioration of respiratory function postoperatively, and the application of positive pressure ventilation (BiPAP®) may be beneficial to restore lung function more quickly, especially vital capacity, safely, and well accepted by patients due to greater comfort with the sensation of pain during the execution of respiratory therapy.

[REDIA--impacts of DRG introduction in the acute sector on medical rehabilitation]. / REDIA - Auswirkungen der DRG-Einführung auf die Rehabilitation.

The REDIA study is the only long-term (2003-2009), prospective, multicentre study analyzing the impact of the DRG system on quality and costs in rehabilitation facilities. In 2004, Diagnosis Related Groups (DRG) were implemented on a mandatory basis in the German healthcare system as a reimbursement scheme for hospitals based on administered prices for procedures. Experiences from other countries revealed that introduction of DRG does not only have a significant impact on hospitals but also on rehabilitation facilities. The study approach ensures a comprehensive analysis as it considers major clinical, therapeutic, psychological and economic aspects. The REDIA study is the only nationwide empirical study that includes all stages of the implementation process: before DRG implementation, during the convergence phase and following implementation. An indication-specific comparison of the phases showed significantly shorter stays in the acute sector as well as shorter transition times between the sectors, resulting in admission of patients into rehabilitative care at an earlier stage of their recovery process. Significant diversions of treatment efforts from the acute sector to the rehabilitative sector have been proven in terms of increased nursing efforts and potential changes in the therapeutic and medical treatments to be provided.

[Health valuations for patients with chronic ischemic heart disease]. / Gesundheitsbewertungen bei Patienten mit chronisch-ischämischer Herzkrankheit.

OBJECTIVE OF THE STUDY: The study deals with the question of how patients with chronic ischemic heart disease assess different health situations that can be achieved by rehabilitation. Furthermore it examines which factors influence these health valuations and whether the predictors vary depending on the level of education. METHODS: The health valuations of n = 331 patients with chronic ischemic heart disease are compiled using visual analogue scales (VAS). In addition to sociodemographic questions, generic and illness-specific scales (SF-12, MacNew) for the health-related quality of life (HRQOL) are used as potential predictors of the health valuations. Additional basic medical data were provided by the physician. Hierarchical regression analyses are conducted; the sociodemographic, medical and HRQOL variables are included stepwise. Since many variables are observed for the regression models, an imputation of missing values is made. RESULTS: The health dimensions "Self-care and domestic life" and "Mobility" are assigned the highest values on the VAS. The lowest preference is assigned to the dimensions "Reduction of symptoms" and "Information about the disease". The differences between the health dimensions are statistically significant. Sociodemographic variables explain up to 3.6% of the variance of health valuations, with level of education and living with a partner being the most important predictors. The medical variables included in the second step explain between 2.1 and 6.8% incremental variance; the most important predictor is the operation performed prior to rehabilitation (bypass, heart valve). The HRQOL variables in the third block provide 7.1-24.9% incremental explanation of variance, by far the highest percentage. This is mainly achieved using the 3 MacNew scales (emotional, social and physical functioning). The overall explanation of variance for the health valuations is 17.1-28.8%. For patients with a higher level of education, the total explanation of variance is about 9.2% higher on average than for the total sample and lies between 21.2 and 44.1%. DISCUSSION: The health dimensions examined are assessed quite differently by the patients. The most significant factor of influence is the HRQOL. In the subgroup of patients with a higher level of education, the predictive strength of the variables examined is considerably higher in comparison with the total sample. Since the health valuations can be predicted to a limited extent only using other data arising during routine care, it is necessary to implement special methods for compiling health valuations.
