Expansion of transcatheter aortic valve replacement in the United States.

BACKGROUND: Patterns of diffusion of TAVR in the United States (U.S.) and its relation to racial disparities in TAVR utilization remain unknown. METHODS: We identified TAVR hospitals in the continental U.S. from 2012-2017 using Medicare database and mapped them to Hospital Referral Regions (HRR). We calculated driving distance from each residential ZIP code to the nearest TAVR hospital and calculated the proportion of the U.S. population, in general and by race, that lived <100 miles driving distance from the nearest TAVR center. Using a discrete time hazard logistic regression model, we examined the association of hospital and HRR variables with the opening of a TAVR program. RESULTS: The number of TAVR hospitals increased from 230 in 2012 to 540 in 2017. The proportion of the U.S. population living <100 miles from nearest TAVR hospital increased from 89.3% in 2012 to 94.5% in 2017. Geographic access improved for all racial and ethnic subgroups: Whites (84.1%-93.6%), Blacks (90.0%- 97.4%), and Hispanics (84.9%-93.7%). Within a HRR, the odds of opening a new TAVR program were higher among teaching hospitals (OR 1.48, 95% CI 1.16-1.88) and hospital bed size (OR 1.44, 95% CI 1.37-1.52). Market-level factors associated with new TAVR programs were proportion of Black (per 1%, OR 0.78, 95% CI 0.69-0.89) and Hispanic (per 1%, OR 0.82, 95% CI 0.75-0.90) residents, the proportion of hospitals within the HRR that already had a TAVR program (per 10%, OR 1.07, 95% CI 1.03-1.11), P <.01 for all. CONCLUSION: The expansion of TAVR programs in the U.S. has been accompanied by an increase in geographic coverage for all racial subgroups. Further study is needed to determine reasons for TAVR underutilization in Blacks and Hispanics.

Cardiac rehabilitation in Portugal: Results from the 2013-14 national survey. / Reabilitação cardíaca em Portugal. Inquérito 2013­2014.

INTRODUCTION: In recent years, cardiac rehabilitation (CR) programs have evolved from being limited to exercise training to comprehensive secondary prevention programs. Given the solid scientific evidence supporting them, they are given a class I recommendation in the American and European guidelines for various cardiovascular diseases, but they continue to be underused in Portugal. OBJECTIVE: To analyze the situation of CR programs in Portugal in 2013-14 and to assess developments in recent years. METHODS: In November 2014, a questionnaire was sent to the centers offering CR programs that included the following items: name of the center; composition of the team; phases and components; number of participants and diagnoses; and funding bodies. The percentage of patients with myocardial infarction admitted to phase II CR programs in 2013 was calculated based on data from the Directorate-General of Health (DGS). RESULTS: Twenty-three centers offering CR programs were identified, 12 public and 11 private. The number of centers rose from 16 in 2007 to 23 in 2014. In 2013, 1927 patients participated in phase II programs, nearly three times the number rehabilitated in 2007 (638 patients). Myocardial infarction was the referral diagnosis in 999 patients, accounting for 51.8% of admissions. On the basis of DGS data, 8% of patients with myocardial infarction were admitted to phase II CRPs in 2013, as opposed to 3% in 2007. CONCLUSION: The number of patients admitted to CR programs, as well as the number of centers, increased considerably between 2007 and 2014 in Portugal. Despite these favorable developments, further improvements are still needed.

Organizational culture in cardiovascular care in Chinese hospitals: a descriptive cross-sectional study.

BACKGROUND: Organizational learning, the process by which a group changes its behavior in response to newly acquired knowledge, is critical to outstanding organizational performance. In hospitals, strong organizational learning culture is linked with improved health outcomes for patients. This study characterizes the organizational learning culture of hospitals in China from the perspective of a cardiology service. METHODS: Using a modified Abbreviated Learning Organization Survey (27 questions), we characterized organizational learning culture in a nationally representative sample of 162 Chinese hospitals, selecting 2 individuals involved with cardiovascular care at each hospital. Responses were analyzed at the hospital level by calculating the average of the two responses to each question. Responses were categorized as positive if they were 5+ on a 7-point scale or 4+ on a 5-point scale. Univariate and multiple regression analyses were used to assess the relationship between selected hospital characteristics and perceptions of organizational learning culture. RESULTS: Of the 324 participants invited to take the survey, 316 responded (98 % response rate). Perceptions of organizational learning culture varied among items, among domains, and both among and within hospitals. Overall, the median proportion of positive responses was 82 % (interquartile range = 59 % to 93 %). "Training," "Performance Monitoring," and "Leadership that Reinforces Learning" were characterized as the most favorable domains, while "Time for Reflection" was the least favorable. Multiple regression analyses showed that region was the only factor significantly correlated with overall positive response rate. CONCLUSIONS: This nationally representative survey demonstrated variation in hospital organizational learning culture among hospitals in China. The variation was not substantially explained by hospital characteristics. Organizational learning culture domains with lower positive response rates reveal important areas for improvement.

Trends in utilization of specialty care centers in California for adults with congenital heart disease.

The American College of Cardiology and American Heart Association guidelines recommend that management of adult congenital heart disease (ACHD) be coordinated by specialty ACHD centers and that ACHD surgery for patients with moderate or complex congenital heart disease (CHD) be performed by surgeons with expertise and training in CHD. Given this, the aim of this study was to determine the proportion of ACHD surgery performed at specialty ACHD centers and to identify factors associated with ACHD surgery being performed outside of specialty centers. This retrospective population analysis used California's Office of Statewide Health Planning and Development's discharge database to analyze ACHD cardiac surgery (in patients 21 to 65 years of age) in California from 2000 to 2011. Designation as a "specialty ACHD center" was defined on the basis of a national ACHD directory. A total of 4,611 ACHD procedures were identified. The proportion of procedures in patients with moderate and complex CHD delivered at specialty centers increased from 46% to 71% from 2000 to 2011. In multivariate analysis among those discharges for ACHD surgery in patients with moderate or complex CHD, performance of surgery outside a specialty center was more likely to be associated with patients who were older, Hispanic, insured by health maintenance organizations, and living farther from a specialty center. In conclusion, although the proportion of ACHD surgery for moderate or complex CHD being performed at specialty ACHD centers has been increasing, 1 in 4 patients undergo surgery at nonspecialty centers. Increased awareness of ACHD care guidelines and of the patient characteristics associated with differential access to ACHD centers may help improve the delivery of appropriate care for all adults with CHD.

King's College London, a cardiac centre of excellence: will it only be possible to deliver the best cardiovascular medicine in 'capital cities' in the future?

New developments at King's College, London, suggest that the complexity of modern cardiovascular medicine, and the enormous prospects for future advances, means that smaller cities will find it hard to compete, reports Barry Shurlock, MA, PhD.

Status and future needs of regional adult congenital heart disease centers in Japan.

BACKGROUND: Although the prevalence of adult congenital heart disease (ACHD) in Japan continues to rise, the number and geographic distribution of facilities potentially serving as regional ACHD centers remains unknown. We examined trends in ACHD care in Japan to identify needs and to determine potential regional responses to this growing patient population. METHODS AND RESULTS: A descriptive, cross-sectional, nationwide survey was conducted to assess the status and needs of cardiology specialists related to providing ACHD care. Questionnaires were mailed to 138 cardiology departments located in 8 geographical regions throughout Japan; respondents were asked to document the status and future direction of ACHD care for each facility. Of the 109 facilities that responded, approximately one-third currently treat or plan to treat all ACHD patients. Fourteen facilities (12.8%) fulfilled all criteria for becoming regional ACHD centers. Although each regional center was projected to serve a population of 9.1 million, in 2 regions, no centers possessed the necessary care structure. CONCLUSIONS: Our findings revealed a shortage of adult cardiologists dedicated to ACHD care. Moreover, basic as well as formal fellowship ACHD training was deemed necessary. In Japan, the number of potential regional ACHD centers has just reached international standards. However, based on the geographic gaps documented here, a strategy other than regional centralization might be required to deliver adequate ACHD care to rural areas.

[Evolution of cardiovascular surgery at the Instituto do Coração: analysis of 71,305 surgeries].

BACKGROUND: Cardiovascular surgery has been undergoing transformations due to the advancement of percutaneous techniques, clinical treatment and primary prevention. OBJECTIVE: Evaluation of incidence and mortality of heart surgeries performed at the Instituto do Coração (InCor-HCFMUSP). METHODS: Using database from the Instituto do Coração, analysis was carried out on cardiovascular surgeries performed between 1984 and 2007, taking into consideration trends of main procedures and of mortality rates. RESULTS: In 24 years, 71,305 heart surgeries were performed, with an annual average of 2971 procedures. The number of coronary artery bypass graft surgeries, which in the 1980s had an average of 856/year, is currently around 1.106/year. Heart valve procedures increased from 400 to 597 surgeries per year, growing 36.7%, when compared to the 1990s. Repair of congenital heart disease also had a significant increase of 50.8% in relation to the last decade. Global mortality average rate, which at baseline was 7.5%, is currently at 7.0% and 4.9% among elective procedures. In coronary artery bypass graft surgery, current average mortality rate is 4.8% and 8.5% in valve surgery. Repair of congenital heart disease accounts for 5.3%. CONCLUSION: Cardiovascular surgery continues increasing. The coronary artery bypass graft is still the most commonly performed surgery. However, profile of procedures has been undergoing changes with the largest increase of approach to cardiac valves and congenital heart disease. Mortality rates are higher when compared to international rates, reflecting the high complexity presented in tertiary service of national reference.

The return of the heart hospital. A hospital that specializes in providing cardiovascular services can meet community needs but will compete with existing community hospitals for market share.

A hospital that provides cardiovascular services and embraces a heart-hospital brand and strategy can achieve competitive advantage. Providers that want to compete aggressively for cardiovascular services are developing a specialty-based carve-out strategy. A heart-hospital initiative can cannibalize revenues from a hospital's other programs and services. A successful heart-hospital strategy requires physician buy-in. A heart hospital needs a brand that customers will value.

15 years of experience with cardiopulmonary resuscitation in the Kingdom of Saudi Arabia: a critical analysis.

The objective of this review is to establish a framework about the educational activities of the Cardiopulmonary Resuscitation (CPR) National Committee of the Saudi Heart Association (SHA) and determine if it has had any effect on the survival rate in daily hospital work. Further, the review puts forward recommendations regarding the key to success for future implementations and improvement in the outcome of heart attacks in the Kingdom of Saudi Arabia (KSA). Cardiopulmonary resuscitation (CPR) was introduced into the Kingdom of Saudi Arabia in the 1980s. The birth of CPR in the Kingdom was conducted by the American Heart Association (AHA) provision of the first instructor course in Basic Cardiac Life Support (BCLS) and Advanced Cardiac Life Support (ACLS) in the spring of 1984. This educational activity was initiated by the Postgraduate Center of the College of Medicine and currently is a function of the Saudi Heart Association (SHA). The National Heart Center (NHC) continually expands its activities. The number of courses organized, conducted, and reported herein totaled 459 for providers and instructors in BCLS and ACLS. This resulted in certification of 916 and 204 instructors in basic and advanced CPR respectively. There were 80 centers established in the Kingdom over the span of 15 years. They all provide BCLS courses; only 13 provide ACLS courses. The SHA issued a total of 84,659 certificates.
