ABSTRACT Disease management is effective in the general population, but it has not been tested prospectively in a sample of solely Hispanics with heart failure (HF). We tested the effectiveness of telephone case management in decreasing hospitalizations and improving health-related quality of life (HRQL) and depression in Hispanics of Mexican origin with HF.
Hospitalized Hispanics with chronic HF (n = 134) were enrolled and randomized to intervention (n = 69) or usual care (n = 65). The sample was elderly (72 +/- 11 years), New York Heart Association class III/IV (81.3%), and poorly educated (78.4% less than high school education). Most (55%) were unacculturated into US society. Bilingual/bicultural Mexican-American registered nurses provided 6 months of standardized telephone case management. Data on hospitalizations were collected from automated systems at 1, 3, and 6 months after the index hospital discharge. Health-related quality of life and depression were measured by self-report at enrollment, 3, and 6 months. Intention to treat analysis was used. No significant group differences were found in HF hospitalizations, the primary outcome variable (usual care: 0.49 +/- 0.81 [CI 0.25-0.73]; intervention: 0.55 +/- 1.1 [CI 0.32-0.78] at 6 months). No significant group differences were found in HF readmission rate, HF days in the hospital, HF cost of care, all-cause hospitalizations or cost, mortality, HRQL, or depression.
These results have important implications because of the current widespread enthusiasm for disease management. Although disease management is effective in the mainstream HF patient population, in Hispanics this ill, elderly, and poorly educated, a different approach may be needed.

    ABSTRACT: Previous studies on telemedicine have either focused on its role in the management of chronic diseases in general or examined its effectiveness in comparison to standard post-discharge care. Little has been done to determine the comparative impact of different telemedicine options for a specific population such as individuals with heart failure (HF). Systematic reviews (SR) of randomized controlled trials (RCTs) that examined telephone support, telemonitoring, video monitoring or electrocardiographic monitoring for HF patients were identified using a comprehensive search of the following databases: MEDLINE, EMBASE, CINAHL and The Cochrane Library. Studies were included if they reported the primary outcome of mortality or any of the following secondary outcomes: all-cause hospitalization and heart failure hospitalization. Thirty RCTs (N = 10,193 patients) were included. Compared to usual care, structured telephone support was found to reduce the odds of mortality(Odds Ratio 0.80; 95% Credible Intervals [0.66 to 0.96]) and hospitalizations due to heart failure (0.69; [0.56 to 0.85]). Telemonitoring was also found to reduce the odds of mortality(0.53; [0.36 to 0.80]) and reduce hospitalizations related to heart failure (0.64; [0.39 to 0.95]) compared to usual post-discharge care. Interventions that involved ECG monitoring also reduced the odds of hospitalization due to heart failure (0.71; [0.52 to 0.98]). Much of the evidence currently available has focused on the comparing either telephone support or telemonitoring with usual care. This has therefore limited our current understanding of how some of the less common forms of telemedicine compare to one another. Compared to usual care, structured telephone support and telemonitoring significantly reduced the odds of deaths and hospitalization due to heart failure. Despite being the most widely studied forms of telemedicine, little has been done to directly compare these two interventions against one another. Further research into their comparative cost-effectiveness is also warranted.

    ABSTRACT: IMPORTANCE Reducing early (<30 days) hospital readmissions is a policy priority aimed at improving health care quality. The cumulative complexity model conceptualizes patient context. It predicts that highly supportive discharge interventions will enhance patient capacity to enact burdensome self-care and avoid readmissions. OBJECTIVE To synthesize the evidence of the efficacy of interventions to reduce early hospital readmissions and identify intervention features-including their impact on treatment burden and on patients' capacity to enact postdischarge self-care-that might explain their varying effects. DATA SOURCES We searched PubMed, Ovid MEDLINE, Ovid EMBASE, EBSCO CINAHL, and Scopus (1990 until April 1, 2013), contacted experts, and reviewed bibliographies. STUDY SELECTION Randomized trials that assessed the effect of interventions on all-cause or unplanned readmissions within 30 days of discharge in adult patients hospitalized for a medical or surgical cause for more than 24 hours and discharged to home. DATA EXTRACTION AND SYNTHESIS Reviewer pairs extracted trial characteristics and used an activity-based coding strategy to characterize the interventions; fidelity was confirmed with authors. Blinded to trial outcomes, reviewers noted the extent to which interventions placed additional work on patients after discharge or supported their capacity for self-care in accordance with the cumulative complexity model. MAIN OUTCOMES AND MEASURES Relative risk of all-cause or unplanned readmission with or without out-of-hospital deaths at 30 days postdischarge. RESULTS In 42 trials, the tested interventions prevented early readmissions (pooled random-effects relative risk, 0.82 [95% CI, 0.73-0.91]; P < .001; I2 = 31%), a finding that was consistent across patient subgroups. Trials published before 2002 reported interventions that were 1.6 times more effective than those tested later (interaction P = .01). In exploratory subgroup analyses, interventions with many components (interaction P = .001), involving more individuals in care delivery (interaction P = .05), and supporting patient capacity for self-care (interaction P = .04) were 1.4, 1.3, and 1.3 times more effective than other interventions, respectively. A post hoc regression model showed incremental value in providing comprehensive, postdischarge support to patients and caregivers. CONCLUSIONS AND RELEVANCE Tested interventions are effective at reducing readmissions, but more effective interventions are complex and support patient capacity for self-care. Interventions tested more recently are less effective.

    ABSTRACT: Cardiovascular disease is the leading cause of death globally. Despite a greater burden of disease, ethnocultural minorities in both the United States and Canada are significantly less likely to access cardiac rehabilitation (CR). Without equitable access to CR, these patients may be more likely to experience recurrent cardiac events and unnecessarily premature death. In this article, the current state of ethnocultural diversity in CR patients and unique barriers that ethnocultural minority patients face are reviewed. Strategies for CR program delivery and diversity of CR program staff are considered. Guidance on ethnocultural considerations in American and Canadian associations of CR is also reviewed. Lower rates of access to CR are seen among ethnocultural minorities in both American and Canadian CR programs. Only 2 studies evaluating ethnoculturally tailored CR could be identified in the literature. American CR staff are predominantly white (∼96%), whereas ethnocultural data are not collected from Canadian CR professionals. American guidelines emphasize the importance of ethnocultural competency. Meanwhile, Canadian guidelines underscore the low use of CR services among ethnocultural minorities, and support ethnoculturally informed CR delivery. The American and Canadian populations are rapidly diversifying, yet the CR workforce is not, and ethnocultural minorities continue to be underrepresented in our programs. Although recent CR guidelines have made some preliminary recommendations to overcome these discrepancies, more focused efforts are needed. Thirteen points of action are proposed for the CR community with the goal of promoting the development and delivery of more ethnoculturally sensitive CR services.
