Temporal trends in tolvaptan use after revision of national heart failure guidelines in Japan.

ABSTRACT: Within no definite diuretic protocol for acute heart failure (AHF) patients and its variation in regional clinical guidelines, the latest national guidelines in Japan commends use of tolvaptan in diuretic-resistant patients. This study aimed to examine trends in tolvaptan usage and associated outcomes of AHF patients requiring hospitalization. Between April, 2018 and October, 2019, 1343 consecutive AHF patients (median 78 [69-85] year-old) were enrolled in a prospective, multicenter registry in Japan. Trends over time in tolvaptan usage, along with the severity of heart failure status based on the Get With The Guideline-Heart Failure [GWTG-HF] risk score, and in-hospital outcomes were investigated. During the study period, tolvaptan usage has increased from 13.0 to 28.7% over time (p for trend = 0.07), and 49.4% started tolvaptan within 3 days after admission. The GWTG-HF risk score in the tolvaptan group has significantly decreased over time, while that in the non-tolvaptan group has unchanged. There were no differences in the in-hospital mortality rate between the patients with and without tolvaptan (6.7% vs. 5.8%). After revision of the Japanese clinical practice guidelines for AHF in March 2018, tolvaptan usage for AHF patients has steadily increased. However, in-hospital outcomes including mortality do not seem to be affected.

Project description:ImportancePrevious studies have described the secular trends of overall heart failure (HF) hospitalizations, but the literature describing the national trends of unique index hospitalizations and readmission visits for the primary management of HF is lacking.ObjectivesTo examine contemporary overall and sex-specific trends of unique primary HF (grouped by number of visits for the same patient in a given year) and 30-day readmission visits in a large national US administrative database from 2010 to 2017.Design, setting, and participantsThis cohort study used data from all adult hospitalizations in the Nationwide Readmission Database from January 1, 2010, to December 31, 2017, with a primary diagnosis of HF. Data analyses were conducted from March to November 2020.ExposuresAdmission for a primary diagnosis of HF at discharge.Main outcomes and measuresUnique and overall hospitalizations with a primary diagnosis of HF and postdischarge readmissions. Unique primary HF hospitalizations were grouped by number of visits for the same patient in a given year.ResultsThere were 8 273 270 primary HF hospitalizations with a single primary HF admission present in 5 092 626 unique patients, and 1 269 109 had 2 or more HF hospitalizations. The mean age was 72.1 (95% CI, 72.0-72.3) years, and 48.9% (95% CI, 48.7-49.0) were women. The primary HF hospitalization rates per 1000 US adults declined from 4.4 in 2010 to 4.1 in 2013 and then increased from 4.2 in 2014 to 4.9 in 2017. The rates per 1000 US adults for postdischarge HF readmissions (1.0 in 2010 to 0.9 in 2014 to 1.1 in 2017) and all-cause 30-day readmissions (0.8 in 2010 to 0.7 in 2014 to 0.9 in 2017) had similar trends.Conclusions and relevanceIn this analysis of a nationally representative administrative data set, for primary HF admissions, crude rates of overall and unique patient hospitalizations declined from 2010 to 2014 followed by an increase from 2014 to 2017. Additionally, readmission visits after index HF hospitalizations followed a similar trend. Future studies are needed to verify these findings to improve policies for HF management.

Project description:Background/objectivesObesity increases with age, is disproportionately prevalent in black populations, and is associated with heart failure with preserved ejection fraction (HFpEF). An "obesity paradox," or improved survival with obesity, has been reported in patients with HFpEF. The aim of this study was to examine whether racial differences exist in the temporal trends and outcomes associated with obesity among older patients with HFpEF.DesignCommunity surveillance of acute decompensated heart failure (ADHF) hospitalizations, sampled by stratified design from 2005 to 2014.SettingAtherosclerosis Risk in Communities Study (NC, MS, MD, MN).ParticipantsA total of 10,147 weighted hospitalizations for ADHF (64% female, 74% white, mean age 77 years), with ejection fraction ≥50%.MeasurementsADHF classified by physician review, HFpEF defined by ejection fraction ≥50%. Body mass index (BMI) calculated from weight at hospital discharge. Obesity defined by BMI ≥30 kg/m2 , class III obesity by BMI ≥40 kg/m2 .ResultsWhen aggregated across 2005-2014, the mean BMI was higher for black compared to white patients (34 vs 30 kg/m2 ; P < .0001), as was prevalence of obesity (56% vs 43%; P < .0001) and class III obesity (24% vs 13%; P < .0001). Over time, the annual mean BMI and prevalence of class III obesity remained stable for black patients, but steadily increased for white patients, with annual rates statistically differing by race (P-interaction = .04 and P = .03, respectively). For both races, a U-shaped adjusted mortality risk was observed across BMI categories, with the highest risk among patients with a BMI ≥40 kg/m2 .ConclusionBlack patients were disproportionately burdened by obesity in this decade-long community surveillance of older hospitalized patients with HFpEF. However, temporal increases in mean BMI and class III obesity prevalence among white patients narrowed the racial difference in recent years. For both races, the worst survival was observed with class III obesity. Effective strategies are needed to manage obesity in patients with HFpEF.

Project description:Importance:Hospitals in the United States have been subject to mandatory public reporting of mortality rates for acute myocardial infarction (AMI) and heart failure (HF) since 2007 and to value-based payment programs for these conditions since 2011. However, whether hospitals with initially poor baseline performance have improved relative to other hospitals under these programs, and whether patterns of improvement differ by condition, is unknown. Understanding trends within public reporting and value-based payment can inform future efforts in these areas. Objective:To examine patterns in 30-day mortality from AMI and HF and determine whether they differ for baseline poor performers (worst quartile in 2009 and 2010 in public reporting, prior to value-based payment) compared with other hospitals. Design, Setting, and Participants:Retrospective cross-sectional study at US acute care hospitals from 2009 to 2015 that included 2751 and 3796 hospitals with publicly reported mortality data for AMI and HF, respectively. Exposures:Public reporting and value-based purchasing. Main Outcomes and Measures:Hospital-level risk-adjusted 30-day mortality rates. Results:We identified 422 and 600 baseline poor-performing hospitals for AMI and HF, respectively. Baseline poor performers for AMI were more often public and for-profit and less often teaching hospitals. Baseline poor performers for HF were less often large hospitals. For AMI, 30-day mortality among baseline poor performers was higher at baseline but improved more over time compared with other hospitals (18.6% in 2009 to 14.6% in 2015; -0.74% per year; P < .001 vs 15.7% in 2009 to 14.0% in 2015; -0.26% per year; P < .001; P for interaction <.001). In contrast, for HF, baseline poor performers improved over time (13.5%-13.0%; -0.12% per year; P < .001), but mean mortality among all other HF hospitals increased during the study period (10.9%-12.0%; 0.17% per year; P < .001; P for interaction, <.001). Conclusions and Relevance:Despite being subject to identical policy pressures, mortality trends for AMI and HF differed markedly between 2009 and 2015.
