RESUMO

Guideline-directed medical therapies and guideline-directed nonpharmacological therapies improve quality of life and survival in patients with heart failure (HF), but eligible patients, particularly women and individuals from underrepresented racial and ethnic groups, are often not treated with these therapies. Implementation science uses evidence-based theories and frameworks to identify strategies that facilitate uptake of evidence to improve health. In this scientific statement, we provide an overview of implementation trials in HF, assess their use of conceptual frameworks and health equity principles, and provide pragmatic guidance for equity in HF. Overall, behavioral nudges, multidisciplinary care, and digital health strategies increased uptake of therapies in HF effectively but did not include equity goals. Few HF studies focused on achieving equity in HF by engaging stakeholders, quantifying barriers and facilitators to HF therapies, developing strategies for equity informed by theory or frameworks, evaluating implementation measures for equity, and titrating strategies for equity. Among these HF equity studies, feasibility was established in using various educational strategies to promote organizational change and equitable care. A couple include ongoing randomized controlled pragmatic trials for HF equity. There is great need for additional HF implementation trials designed to promote delivery of equitable guideline-directed therapy.

RESUMO

Despite significant progress in medical research and public health efforts, gaps in knowledge of women's heart health remain across epidemiology, presentation, management, outcomes, education, research, and publications. Historically, heart disease was viewed primarily as a condition in men and male individuals, leading to limited understanding of the unique risks and symptoms that women experience. These knowledge gaps are particularly problematic because globally heart disease is the leading cause of death for women. Until recently, sex and gender have not been addressed in cardiovascular research, including in preclinical and clinical research. Recruitment was often limited to male participants and individuals identifying as men, and data analysis according to sex or gender was not conducted, leading to a lack of data on how treatments and interventions might affect female patients and individuals who identify as women differently. This lack of data has led to suboptimal treatment and limitations in our understanding of the underlying mechanisms of heart disease in women, and is directly related to limited awareness and knowledge gaps in professional training and public education. Women are often unaware of their risk factors for heart disease or symptoms they might experience, leading to delays in diagnosis and treatments. Additionally, health care providers might not receive adequate training to diagnose and treat heart disease in women, leading to misdiagnosis or undertreatment. Addressing these knowledge gaps requires a multipronged approach, including education and policy change, built on evidence-based research. In this chapter we review the current state of existing cardiovascular research in Canada with a specific focus on women.


En dépit des avancées importantes de la recherche médicale et des efforts en santé publique, il reste des lacunes dans les connaissances sur la santé cardiaque des femmes sur les plans de l'épidémiologie, du tableau clinique, de la prise en charge, des résultats, de l'éducation, de la recherche et des publications. Du point de vue historique, la cardiopathie a d'abord été perçue comme une maladie qui touchait les hommes et les individus de sexe masculin. De ce fait, la compréhension des risques particuliers et des symptômes qu'éprouvent les femmes est limitée. Ces lacunes dans les connaissances posent particulièrement problème puisqu'à l'échelle mondiale la cardiopathie est la cause principale de décès chez les femmes. Jusqu'à récemment, la recherche en cardiologie, notamment la recherche préclinique et clinique, ne portait pas sur le sexe et le genre. Le recrutement souvent limité aux participants masculins et aux individus dont l'identité de genre correspond au sexe masculin et l'absence d'analyses de données en fonction du sexe ou du genre ont eu pour conséquence un manque de données sur la façon dont les traitements et les interventions nuisent aux patientes féminines et aux individus dont l'identité de genre correspond au sexe féminin, et ce, de façon différente. Cette absence de données a mené à un traitement sous-optimal et à des limites de notre compréhension des mécanismes sous-jacents de la cardiopathie chez les femmes, et est directement reliée à nos connaissances limitées, et à nos lacunes en formation professionnelle et en éducation du public. Le fait que les femmes ne connaissent souvent pas leurs facteurs de risque de maladies du cœur ou les symptômes qu'elles peuvent éprouver entraîne des retards de diagnostic et de traitements. De plus, le fait que les prestataires de soins de santé ne reçoivent pas la formation adéquate pour poser le diagnostic et traiter la cardiopathie chez les femmes les mène à poser un mauvais diagnostic ou à ne pas traiter suffisamment. Pour pallier ces lacunes de connaissances, il faut une approche à plusieurs volets, qui porte notamment sur l'éducation et les changements dans les politiques, et qui repose sur la recherche fondée sur des données probantes. Dans ce chapitre, nous passons en revue l'état actuel de la recherche existante sur les maladies cardiovasculaires au Canada, plus particulièrement chez les femmes.

RESUMO

BACKGROUND: Guideline-directed medical therapies (GDMTs) are the mainstay of treatment for heart failure with reduced ejection fraction (HFrEF), but they are underused. Whether sex differences exist in the initiation and intensification of GDMT for newly diagnosed HFrEF is not well established. METHODS: Patients with incident HFrEF were identified from the 2016 to 2020 Optum deidentified Clinformatics Data Mart Database, which is derived from a database of administrative health claims for members of large commercial and Medicare Advantage health plans. The primary outcome was the use of optimal GDMT within 12 months of HFrEF diagnosis. Consistent with the guideline recommendations during the time period of the study, optimal GDMT was defined as ≥50% of the target dose of evidence-based beta-blocker plus ≥50% of the target dose of angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, or any dose of angiotensin receptor neprilysin inhibitor plus any dose of mineralocorticoid receptor antagonist. The probability of achieving optimal GDMT on follow-up and predictors of optimal GDMT were evaluated with time-to-event analysis with adjusted Cox proportional hazard models. RESULTS: The study cohort included 63 759 patients (mean age, 71.3 years; 15.2% non-Hispanic Black race; 56.6% male). Optimal GDMT use was achieved by 6.2% of patients at 12 months after diagnosis. Female (compared with male) patients with HFrEF had lower use across every GDMT class and lower use of optimal GDMT at each time point at follow-up. In an adjusted Cox model, female sex was associated with a 23% lower probability of achieving optimal GDMT after diagnosis (hazard ratio [HR], 0.77 [95% CI, 0.71-0.83]; P<0.001). The sex disparities in GDMT use after HFrEF diagnosis were most pronounced among patients with commercial insurance (females compared with males; HR, 0.66 [95% CI, 0.58-0.76]) compared with Medicare (HR, 0.85 [95% CI, 0.77-0.92]); Pinteraction sex×insurance status=0.005) and for younger patients (age <65 years: HR, 0.65 [95% CI, 0.58-0.74]) compared with older patients (age ≥65 years: HR, 87 [95% CI, 80-96]) Pinteraction sex×age=0.009). CONCLUSIONS: Overall use of optimal GDMT after HFrEF diagnosis was low, with significantly lower use among female (compared with male) patients. These findings highlight the need for implementation efforts directed at improving GDMT initiation and titration.

RESUMO

BACKGROUND: Utilization patterns of bariatric surgery among older patients with heart failure (HF), and the associations with cardiovascular outcomes, are not well known. METHODS: Medicare beneficiaries with HF and at least class II obesity from 2013 to 2020 were identified with Medicare Provider Analysis and Review 100% inpatient files and Medicare 5% outpatient files. Patients who underwent bariatric surgery were matched to controls in a 1:2 ratio (matched on exact age, sex, race, body mass index, HF encounter year, and HF hospitalization rate pre-surgery/matched period). In an exploratory analysis, patients prescribed pharmacotherapies with weight loss effects (semaglutide, liraglutide, naltrexone-bupropion, or orlistat) were identified and matched to controls with a similar strategy in addition to HF medical therapy data. Cox models evaluated associations between weight loss therapies (as a time-varying covariate) and mortality risk and HF hospitalization rate (calculated as the rate of HF hospitalizations following index HF encounter per 100 person-months) during follow-up. RESULTS: Of 298 101 patients with HF and body mass index ≥35 kg/m2, 2594 (0.9%) underwent bariatric surgery (45% men; mean age, 56.2 years; mean body mass index, 51.5 kg/m2). In propensity-matched analyses over a median follow-up of 4.7 years, bariatric surgery was associated with lower risk of all-cause mortality (HR, 0.55 [95% CI, 0.49-0.63]; P<0.001), greater reduction in HF hospitalization rate (rate ratio, 0.72 [95% CI, 0.67-0.77]; P<0.001), and lower atrial fibrillation risk (HR, 0.78 [95% CI, 0.65-0.93]; P=0.006). Use of pharmacotherapies with weight loss effects was low (4.8%), with 96.3% prescribed GLP-1 (glucagon-like peptide-1) agonists (semaglutide, 23.6%; liraglutide, 72.7%). In propensity-matched analysis over a median follow-up of 2.8 years, patients receiving pharmacotherapies with weight loss effects (versus matched controls) had a lower risk of all-cause mortality (HR, 0.82 [95% CI, 0.71-0.95]; P=0.007) and HF hospitalization rate (rate ratio, 0.87 [95% CI, 0.77-0.99]; P=0.04). CONCLUSIONS: Bariatric surgery and pharmacotherapies with weight loss effects are associated with a lower risk of adverse outcomes among older patients with HF and obesity; however, overall utilization remains low.

RESUMO

Hospital at home (HaH) is an innovative care model that may be particularly suited for heart failure (HF). Outpatient visits and inpatient care have been the 2 traditional settings for HF care, yet may not match the social and medical needs of patients at all times. Alternative models such as HaH may represent an effective and patient-centered option for select patients with worsening HF. To date, limited research in HF and other disease states has supported HaH as being safe and lower cost than traditional inpatient admission. Supporting HaH are new payment structures, such as Medicare's Acute Hospital Care at Home waiver program. In combination with outpatient visits, outpatient intravenous diuretic clinics, inpatient care, and cardiac intensive care, HaH could be a core component of a comprehensive care model with the potential to match resource utilization with the needs of patients across the spectrum of HF severity, and improve patient outcomes.

RESUMO

AIMS: Heart failure with reduced ejection fraction (HFrEF) is treatable but guideline-directed medical therapy (GDMT) may not be affordable or accessible to people living with the disease. METHODS AND RESULTS: In this cross-sectional survey, we investigated the price, affordability, and accessibility of four pivotal classes of HFrEF GDMT: angiotensin-converting enzyme inhibitors (ACEi), angiotensin receptor blockers (ARB) or angiotensin-neprilysin inhibitors (ARNI); beta-blockers; mineralocorticoid receptor antagonists (MRA); and sodium glucose co-transporter 2 inhibitors (SGLT2i). We sampled online or community pharmacies in 10 countries across a range of World Bank income groups, assessing mean 30 day retail prescription prices, affordability relative to gross national income per capita per month, and accessibility. We reported median price ratios relative to the International Reference Standard. We performed a literature review to evaluate accessibility to GDMT classes through publicly funded drug programmes in each country. HFrEF GDMT prices, both absolute and relative to the international reference, were highest in the United States and lowest in Pakistan and Bangladesh. The most expensive drug was the ARNI, sacubitril/valsartan, with a mean (standard deviation, SD) 30 day price ranging from $11.06 (0.81) in Pakistan to $611.50 (3.54) in United States. The least expensive drug was the MRA, spironolactone, with a mean (SD) 30 day price ranging from $0.18 (0.00) in Pakistan to $12.32 (0.00) in England. Affordability (SD) of quadruple therapy-ARNI, beta-blockers, MRA, and SGLT2i-was best in high-income and worst in low-income countries, ranging from 1.49 (0.00)% of gross national income per capita per month in England to 232.47 (31.47)% in Uganda. Publicly funded drug programmes offset costs for eligible patients, but ARNI and SGLT2i were inaccessible through these programmes in low- and middle-income countries. Price, affordability, and access were substantially improved in all countries by substituting ARNI for ACEi/ARB. CONCLUSIONS: There was marked variation between countries in the retail price of HFrEF GDMT. Despite higher prices in high-income countries, GDMT was more accessible and affordable than in low- and middle-income countries. Publicly funded drug programmes in lower income countries increased affordability but limited access to newer HFrEF GDMT classes. Pharmaco-disparities must be addressed to improve HFrEF outcomes globally.

RESUMO

Heart failure (HF) is a global public health concern that affects millions of people worldwide. While there have been significant therapeutic advancements in HF over the last few decades, there remain major disparities in risk factors, treatment patterns and outcomes across race, ethnicity, socioeconomic status, country and region. Recent research has provided insight into many of these disparities, but there remain large gaps in our understanding of worldwide variations in HF care. Although the majority of the global population resides across Asia, Africa and South America, these regions remain poorly represented in epidemiological studies and HF trials. Recent efforts and registries have provided insight into the clinical profiles and outcomes across HF patterns globally. The prevalence of HF and associated risk factors has been reported and varies by country and region ranges, with minimal data on regional variations in treatment patterns and long-term outcomes. It is critical to improve our understanding of the different factors that contribute to global disparities in HF care so we can build interventions that improve our general cardiovascular health and mitigate the social and economic cost of HF. In this narrative review, we hope to provide an overview of the global and regional variations in HF care and outcomes.

RESUMO

This chapter summarizes the sex- and gender-specific diagnosis and treatment of acute/unstable presentations and nacute/stable presentations of cardiovascular disease in women. Guidelines, scientific statements, systematic reviews/meta-analyses, and primary research studies related to diagnosis and treatment of coronary artery disease, cerebrovascular disease (stroke), valvular heart disease, and heart failure in women were reviewed. The evidence is summarized as a narrative, and when available, sex- and gender-specific practice and research recommendations are provided. Acute coronary syndrome presentations and emergency department delays are different in women than they are in men. Coronary angiography remains the gold-standard test for diagnosis of obstructive coronary artery disease. Other diagnostic imaging modalities for ischemic heart disease detection (eg, positron emission tomography, echocardiography, single-photon emission computed tomography, cardiovascular magnetic resonance, coronary computed tomography angiography) have been shown to be useful in women, with their selection dependent upon both the goal of the individualized assessment and the testing resources available. Noncontrast computed tomography and computed tomography angiography are used to diagnose stroke in women. Although sex-specific differences appear to exist in the efficacy of standard treatments for diverse presentations of acute coronary syndrome, many cardiovascular drugs and interventions tested in clinical trials were not powered to detect sex-specific differences, and knowledge gaps remain. Similarly, although knowledge is evolving about sex-specific difference in the management of valvular heart disease, and heart failure with both reduced and preserved ejection fraction, current guidelines are lacking in sex-specific recommendations, and more research is needed.


Ce chapitre présente un résumé sur le diagnostic et le traitement des tableaux cliniques aigus/instables et non aigus/stables des maladies cardiovasculaires chez les femmes, et les différences propres à chacun des deux sexes. Les lignes directrices, les énoncés scientifiques, les revues systématiques/méta-analyses et les études de recherche originale sur le diagnostic et le traitement des coronaropathies, des maladies vasculaires cérébrales (AVC), des valvulopathies cardiaques et de l'insuffisance cardiaque chez les femmes ont été examinés. Les données probantes sont résumées sous forme narrative et, lorsqu'elles sont disponibles, des recommandations en matière de pratique et de recherche pour chacun des deux sexes sont présentées. Les tableaux cliniques du syndrome coronarien aigu et les délais d'attente à l'urgence sont différents selon qu'une femme ou un homme en est atteint. L'angiographie coronarienne reste l'examen de référence pour le diagnostic des coronaropathies obstructives. D'autres examens d'imagerie diagnostique (p. ex. la tomographie par émission de positons, l'échocardiographie, la tomographie d'émission à photon unique, la résonance magnétique cardiovasculaire, l'angiographie coronarienne par tomodensitométrie) se sont avérés utiles pour la détection des cardiopathies ischémiques chez les femmes. Le recours à ces modalités dépend de l'objectif de l'évaluation personnalisée et des ressources disponibles. La tomodensitométrie sans agent de contraste et l'angiographie par tomodensitométrie sont utilisées pour le diagnostic des AVC chez les femmes. Malgré les différences entre les sexes quant à l'efficacité des traitements de référence des divers tableaux cliniques du syndrome coronarien aigu, bon nombre des médicaments et des interventions cardiovasculaires qui ont fait l'objet d'essais cliniques n'avaient pas la puissance statistique nécessaire pour détecter des différences selon les sexes, de sorte que les connaissances restent fragmentaires sur ce sujet. De même, malgré l'évolution des connaissances sur les différences sexuelles quant à la prise en charge des valvulopathies cardiaques et de l'insuffisance cardiaque avec fraction d'éjection réduite ou préservée, on ne trouve pas de recommandations pour chaque sexe dans les lignes directrices actuelles, d'où la pertinence d'études supplémentaires portant sur cette question.

RESUMO

BACKGROUND: In 2018, United Network for Organ Sharing (UNOS) extended the radius for which a heart transplant candidate can match with a donor, and outcomes across population densities are unknown. We sought to determine whether the policy change was associated with differences in heart transplant waitlist time or death post-transplant for patients from rural, micropolitan, and metropolitan settings. METHODS: Using the Scientific Registry of Transplant Recipients, we evaluated U.S. adult patients listed for heart transplant from Janurary 2017 to September 2019 with follow-up through March 2020. Patients were stratified by home zip-codes to either metropolitan, micropolitan, or rural settings. Fine and Gray and Cox models were respectively used to estimate Sub-distribution hazard ratios (SHR) of heart transplant with death or removal from transplant list as a competing event, and HR of death post-transplant within population densities after versus before the UNOS policy change date, October 18, 2018. Analyses were adjusted for demographics, comorbidities, and labs. RESULTS: Among 8,747 patients listed for heart transplant, 84.7% were from metropolitan, 8.6% micropolitan, and 6.6% rural settings. The 2018 UNOS policy was associated with earlier receipt of heart transplant for metropolitan [SHR 1.56 (95% CI: 1.46-1.66)] and micropolitan [SHR 1.48 (95% CI: 1.21-1.82)] populations, but not significantly for rural [SHR 1.20 (95% CI: 0.93-1.54)]; however, the interaction between policy and densities was not significant (p = .14). Policy changes were not associated with risk of death post-transplant [metropolitan: HR 1.04 (95% CI: 0.80-1.34); micropolitan: HR 1.10 (95% CI: 0.55-2.23); rural: HR 1.04 (95% CI: 0.52-2.08); interaction p = .99]. CONCLUSIONS: The 2018 UNOS heart transplant policy was associated with earlier receipt of heart transplant and no difference in post-transplant survival within population densities. Additional follow-up is needed to determine whether improvements are sustained.

RESUMO

This Atlas chapter summarizes sex- and some gender-associated, and unique aspects and manifestations of cardiovascular disease (CVD) in women. CVD is the primary cause of premature death in women in Canada and numerous sex-specific differences related to symptoms and pathophysiology exist. A review of the literature was done to identify sex-specific differences in symptoms, pathophysiology, and unique manifestations of CVD in women. Although women with ischemic heart disease might present with chest pain, the description of symptoms, delay between symptom onset and seeking medical attention, and prodromal symptoms are often different in women, compared with men. Nonatherosclerotic causes of angina and myocardial infarction, such as spontaneous coronary artery dissection are predominantly identified in women. Obstructive and nonobstructive coronary artery disease, aortic aneurysmal disease, and peripheral artery disease have worse outcomes in women compared with men. Sex differences exist in valvular heart disease and cardiomyopathies. Heart failure with preserved ejection fraction is more often diagnosed in women, who experience better survival after a heart failure diagnosis. Stroke might occur across the lifespan in women, who are at higher risk of stroke-related disability and age-specific mortality. Sex- and gender-unique differences exist in symptoms and pathophysiology of CVD in women. These differences must be considered when evaluating CVD manifestations, because they affect management and prognosis of cardiovascular conditions in women.


Dans le présent chapitre d'Atlas sont récapitulés les aspects et les manifestations uniques, associés au sexe et certains associés au genre, des maladies cardiovasculaires (MCV) chez les femmes. Les MCV sont la cause principale de décès prématurés chez les femmes au Canada. De nombreuses différences quant aux symptômes et à la physiopathologie existent entre les sexes. Nous avons réalisé une revue de la littérature pour déterminer les différences entre les sexes dans les symptômes et la physiopathologie, et les manifestations uniques des MCV chez les femmes. Bien que les femmes atteintes d'une cardiopathie ischémique puissent éprouver des douleurs thoraciques, la description des symptômes, le délai entre l'apparition des symptômes et l'obtention de soins médicaux, et les symptômes prodromiques sont souvent différents de ceux des hommes. Les causes de l'angine et de l'infarctus du myocarde non liées à l'athérosclérose telles que la dissection spontanée de l'artère coronaire sont principalement observées chez les femmes. La coronaropathie obstructive et non obstructive, l'anévrisme aortique et la maladie artérielle périphérique montrent de plus mauvaises issues chez les femmes que chez les hommes. Des différences entre les sexes sont observées dans la cardiopathie valvulaire et les cardiomyopathies. Le diagnostic d'insuffisance cardiaque avec fraction d'éjection préservée est plus souvent posé chez les femmes qui présentent un meilleur taux de survie après un diagnostic d'insuffisance cardiaque. L'accident vasculaire cérébral (AVC) pourrait survenir tout au long de la vie des femmes, qui sont exposées à un risque plus élevé d'incapacités liées à l'AVC et de mortalité par âge. Il existe des différences uniques entre les sexes et les genres pour ce qui est des symptômes et de la physiopathologie des MCV chez les femmes. Lors de l'évaluation des manifestations des MCV, il faut tenir compte de ces différences puisqu'elles influencent la prise en charge et le pronostic des maladies cardiovasculaires chez les femmes.

RESUMO

BACKGROUND: Deaths in the first year of the Coronavirus Disease 2019 (COVID-19) pandemic in England and Wales were unevenly distributed socioeconomically and geographically. However, the full scale of inequalities may have been underestimated to date, as most measures of excess mortality do not adequately account for varying age profiles of deaths between social groups. We measured years of life lost (YLL) attributable to the pandemic, directly or indirectly, comparing mortality across geographic and socioeconomic groups. METHODS AND FINDINGS: We used national mortality registers in England and Wales, from 27 December 2014 until 25 December 2020, covering 3,265,937 deaths. YLLs (main outcome) were calculated using 2019 single year sex-specific life tables for England and Wales. Interrupted time-series analyses, with panel time-series models, were used to estimate expected YLL by sex, geographical region, and deprivation quintile between 7 March 2020 and 25 December 2020 by cause: direct deaths (COVID-19 and other respiratory diseases), cardiovascular disease and diabetes, cancer, and other indirect deaths (all other causes). Excess YLL during the pandemic period were calculated by subtracting observed from expected values. Additional analyses focused on excess deaths for region and deprivation strata, by age-group. Between 7 March 2020 and 25 December 2020, there were an estimated 763,550 (95% CI: 696,826 to 830,273) excess YLL in England and Wales, equivalent to a 15% (95% CI: 14 to 16) increase in YLL compared to the equivalent time period in 2019. There was a strong deprivation gradient in all-cause excess YLL, with rates per 100,000 population ranging from 916 (95% CI: 820 to 1,012) for the least deprived quintile to 1,645 (95% CI: 1,472 to 1,819) for the most deprived. The differences in excess YLL between deprivation quintiles were greatest in younger age groups; for all-cause deaths, a mean of 9.1 years per death (95% CI: 8.2 to 10.0) were lost in the least deprived quintile, compared to 10.8 (95% CI: 10.0 to 11.6) in the most deprived; for COVID-19 and other respiratory deaths, a mean of 8.9 years per death (95% CI: 8.7 to 9.1) were lost in the least deprived quintile, compared to 11.2 (95% CI: 11.0 to 11.5) in the most deprived. For all-cause mortality, estimated deaths in the most deprived compared to the most affluent areas were much higher in younger age groups, but similar for those aged 85 or over. There was marked variability in both all-cause and direct excess YLL by region, with the highest rates in the North West. Limitations include the quasi-experimental nature of the research design and the requirement for accurate and timely recording. CONCLUSIONS: In this study, we observed strong socioeconomic and geographical health inequalities in YLL, during the first calendar year of the COVID-19 pandemic. These were in line with long-standing existing inequalities in England and Wales, with the most deprived areas reporting the largest numbers in potential YLL.

RESUMO

Importance: Digital health programs may have the potential to prevent hospitalizations among patients with chronic diseases by supporting patient self-management, symptom monitoring, and coordinated care. Objective: To compare the effect of an internet-based self-management and symptom monitoring program targeted to patients with 2 or more chronic diseases (internet chronic disease management [CDM]) with usual care on hospitalizations over a 2-year period. Design, Setting, and Participants: This single-blinded randomized clinical trial included patients with multiple chronic diseases from 71 primary care clinics in small urban and rural areas throughout British Columbia, Canada. Recruitment occurred between October 1, 2011, and March 23, 2015. A volunteer sample of 456 patients was screened for eligibility. Inclusion criteria included daily internet access, age older than 19 years, fluency in English, and the presence of 2 or more of the following 5 conditions: diabetes, heart failure, ischemic heart disease, chronic kidney disease, or chronic obstructive pulmonary disease. A total of 230 patients consented to participate and were randomized to receive either the internet CDM intervention (n = 117) or usual care (n = 113). One participant in the internet CDM group withdrew from the study after randomization, resulting in 229 participants for whom data on the primary outcome were available. Interventions: Internet-based self-management program using telephone nursing supports and integration within primary care compared with usual care over a 2-year period. Main Outcomes and Measures: The primary outcome was all-cause hospitalizations at 2 years. Secondary outcomes included hospital length of stay, quality of life, self-management, and social support. Additional outcomes included the number of participants with at least 1 hospitalization, the number of participants who experienced a composite outcome of all-cause hospitalization or death, the time to first hospitalization, and the number of in-hospital days. Results: Among 229 participants included in the analysis, the mean (SD) age was 70.5 (9.1) years, and 141 participants (61.6%) were male; data on race and ethnicity were not collected because there was no planned analysis of these variables. The internet CDM group had 25 fewer hospitalizations compared with the usual care group (56 hospitalizations vs 81 hospitalizations, respectively [30.9% reduction]; relative risk [RR], 0.68; 95% CI, 0.43-1.10; P = .12). The intervention group also had 229 fewer in-hospital days compared with the usual care group (282 days vs 511 days, respectively; RR, 0.52; 95% CI, 0.24-1.10; P = .09). Components of self-management and social support improved in the intervention group. Fewer participants in the internet CDM vs usual care group had at least 1 hospitalization (32 of 116 individuals [27.6%] vs 46 of 113 individuals [40.7%]; odds ratio [OR], 0.55; 95% CI, 0.31-0.96; P = .03) or experienced the composite outcome of all-cause hospitalization or death (37 of 116 individuals [31.9%] vs 51 of 113 individuals [45.1%]; OR, 0.57; 95% CI, 0.33-0.98; P = .04). Participants in the internet CDM group had a lower risk of time to first hospitalization (hazard ratio, 0.62; 95% CI, 0.39-0.97; P = .04) than those in the usual care group. Conclusions and Relevance: In this study, an internet-based self-management program did not result in a significant reduction in hospitalization. However, fewer participants in the intervention group were admitted to the hospital or experienced the composite outcome of all-cause hospitalization or death. These findings suggest the internet CDM program has the potential to augment primary care among patients with multiple chronic diseases.

RESUMO

BACKGROUND: There is limited evidence on the influence of sex on the decision to implant a cardiac resynchronization therapy device with pacemaker (CRT-P) or defibrillator (CRT-D) and the existence of sex-dependent differences in complications that may affect this decision. METHODS: All patients undergoing de novo CRT implantation (2004-2014) in the United States National Inpatient Sample were included and stratified by device type (CRT-P and CRT-D). Multivariable logistic regression models were conducted to assess the association of female sex with receipt of CRT-D and periprocedural complications. RESULTS: Out of 400,823 weighted CRT procedural records, the overall percentages of women undergoing CRT-P and CRT-D implantations were 41.5% and 27.8%, respectively, and these percentages increased compared with men over the study period. Women were less likely to receive CRT-D (odds ratio 0.66, 95% confidence interval 0.64-0.67), and this trend remained stable throughout the study period (P = 0.06). Furthermore, compared with men, women were associated with increased odds of procedure-related complications (bleeding, thoracic, and cardiac) in the CRT-D group but not in the CRT-P group. Factors such as atrial fibrillation, malignancies, renal failure, advanced age (> 60 years), and admission to nonurban/small hospitals favoured the receipt of CRT-P over CRT-D, whereas history of ischemic heart disease, cardiac arrest ,or ventricular arrhythmias favoured the receipt of CRT-D over CRT-P. CONCLUSIONS: Women were associated with persistently reduced odds of receipt of CRT-D compared with men over an 11-year period. This study identifies important factors that predict the choice of CRT device offered to patients in the United States.

RESUMO

Background Patients with chronic disease prefer an adequately supported death at home, but often die in the hospital. We assessed temporal trends and sex differences in healthcare intensity and location of death among decedents with heart failure. Methods and Results This was a retrospective cohort study of adults with heart failure who died between April 1, 2004 and March 31, 2017 in Ontario, Canada. We used population-based administrative databases to assess healthcare utilization during the last 6 months of life and applied multilevel multivariable logistic regression to assess whether sex was independently associated with location of death. Among 396 024 decedents with heart failure, mean (SD) age was 81.8 (10.7) years, 51.5% were women, and 53.4% had in-hospital deaths. From 2004 to 2016, there was an increase in patients receiving mechanical ventilation (15.1%-19.6%), hemodialysis (5.2%-6.8%), and cardiac revascularization (1.7%-2.3%). Relative to men, women spent fewer days in a hospital (mean, 16.4 versus 18.3; mean difference, 1.9; 95% CI, 1.7-2.0; P<0.001) and in an intensive care unit (mean, 2.1 versus 3.0; mean difference, 0.9; 95% CI, 0.8-0.9; P<0.001); and less commonly received mechanical ventilation (15.5% versus 20.8%; P<0.001); hemodialysis (4.8% versus 7.7%; P<0.001); or cardiac catheterization (2.8% versus 4.6%; P<0.001). Female sex was independently associated with lower odds of in-hospital death (odds ratio, 0.88; 95% CI, 0.87-0.89). Mean (SD) 6-month direct healthcare cost was greater for in-hospital ($52 349 [$55 649]) than out-of-hospital ($35 998 [$31 900]) death. Conclusions Among decedents with heart failure, invasive care in the last 6 months increased in prevalence over time but was less common in women, who had lower odds of dying in a hospital.

RESUMO

BACKGROUND: Heart failure hospitalizations are a major financial cost to healthcare systems. This study aimed to evaluate the costs associated with inpatient hospitalization. METHODS: Patients with a primary diagnosis of heart failure during a hospital admission between 2010 and 2014 in the U.S. Nationwide Readmission Database were included. The primary outcome was total cost defined by direct cost of index admission and first readmission within 30-days. RESULTS: A total of 2,645,336 patients with primary heart failure were included in the analysis. The mean ± SD total cost overall was $13,807 ± 24,145; with mean total costs of $15,618 ± 25,264 for patients with 30-day readmission and $11,845 ± 22,710 for patients without a readmission. The comorbidities strongly associated with increased cost were pulmonary circulatory disorder (OR 26.24 95% CI 20.06-34.33), valvular heart disease (OR 25.42 95% CI 20.65-31.28) and bleeding (OR 5.96 95% CI 5.47-6.50). Among hospitalized patients, 12.6% underwent an invasive diagnostic procedure or treatment. The mean cost for patients without invasive care was $10,995. This increased by $129,547, $119,769, $251,110 and $293,575 for receipt of circulatory support, intra-aortic balloon pump, LV assist device and heart transplant. The greatest mean additional cost annually was associated with receipt of coronary angiogram ($26,282 per person for a total of ($728.5 million) and mechanical ventilation ($54,529 per person for a total of $501.7 million). CONCLUSION: In conclusion, the costs associated with inpatient heart failure care are significant, and the major contributors to inpatient costs are comorbidities, invasive procedures and readmissions.

RESUMO

BACKGROUND: Little is known about frailty amongst patients hospitalized with heart failure (HF) on a national level. METHODS: We conducted a retrospective cohort study of patients admitted to hospital for HF in the United States. We examined how low, intermediate and high risk of frailty as defined by the Hospital Frailty Risk Score has changed over time and how it is related to inpatient mortality, length of stay, cost and discharge location. RESULTS: We included 11,626,400 inpatient episodes for HF. The proportions of patients that had low risk, intermediate and high risk of frailty were 80.0% (n = 9,300,873), 19.9% (n = 2,314,001) and 0.1% (n = 11,526). Intermediate or high risk of frailty increased from 9.9% in 2004 to 31.7% in 2014. Length of stay in hospital was greater in the high compared to low risk groups (11.3 days vs 4.6 days, respectively). The cost of admission was also greater in the high risk group ($23,084 ±â€¯39,681) compared to the low risk group ($9103 ±â€¯12,768). Intermediate and high risk of frailty groups were associated with increased in odds of mortality (OR 2.38 95% CI 2.22-2.34, p < 0.001 and OR 3.05 95%CI 2.57-3.62, p < 0.001, respectively) and discharge to nursing facilities (intermediate risk OR 1.52 95%CI 1.50-1.54, p < 0.001 and high risk OR 1.60 95%CI 1.35-1.90, p < 0.001). CONCLUSIONS: Frailty is significant and increasing in a national cohort of patients with HF in the United States. Patients at higher risk of frailty have increased in-hospital mortality, length of stay and inpatient costs, and a greater proportion are discharged to nursing home.

RESUMO

OBJECTIVES: To identify factors that differentiate between effective and ineffective computerised clinical decision support systems in terms of improvements in the process of care or in patient outcomes. DESIGN: Meta-regression analysis of randomised controlled trials. DATA SOURCES: A database of features and effects of these support systems derived from 162 randomised controlled trials identified in a recent systematic review. Trialists were contacted to confirm the accuracy of data and to help prioritise features for testing. MAIN OUTCOME MEASURES: "Effective" systems were defined as those systems that improved primary (or 50% of secondary) reported outcomes of process of care or patient health. Simple and multiple logistic regression models were used to test characteristics for association with system effectiveness with several sensitivity analyses. RESULTS: Systems that presented advice in electronic charting or order entry system interfaces were less likely to be effective (odds ratio 0.37, 95% confidence interval 0.17 to 0.80). Systems more likely to succeed provided advice for patients in addition to practitioners (2.77, 1.07 to 7.17), required practitioners to supply a reason for over-riding advice (11.23, 1.98 to 63.72), or were evaluated by their developers (4.35, 1.66 to 11.44). These findings were robust across different statistical methods, in internal validation, and after adjustment for other potentially important factors. CONCLUSIONS: We identified several factors that could partially explain why some systems succeed and others fail. Presenting decision support within electronic charting or order entry systems are associated with failure compared with other ways of delivering advice. Odds of success were greater for systems that required practitioners to provide reasons when over-riding advice than for systems that did not. Odds of success were also better for systems that provided advice concurrently to patients and practitioners. Finally, most systems were evaluated by their own developers and such evaluations were more likely to show benefit than those conducted by a third party.
