Abstract Aims Haematopoietic stem cell transplantation (HSCT) is a potentially curative therapy for several malignant and non-malignant haematologic conditions. Patients undergoing HSCT are at an increased risk of developing atrial fibrillation (AF). We hypothesized that a diagnosis of AF would be associated with poor outcomes in patients undergoing HSCT. Methods and results The National Inpatient Sample (2016–19) was queried with ICD-10 codes to identify patients aged >50 years undergoing HSCT. Clinical outcomes were compared between patients with and without AF. A multivariable regression model adjusting for demographics and comorbidities was used to calculate the adjusted odds ratio (aOR) and regression coefficients with corresponding 95% confidence intervals and P-values. A total of 50 570 weighted hospitalizations for HSCT were identified, out of which 5820 (11.5%) had AF. Atrial fibrillation was found to be independently associated with higher inpatient mortality (aOR 2.75; 1.9–3.98; P < 0.001), cardiac arrest (aOR 2.86; 1.55–5.26; P = 0.001), acute kidney injury (aOR 1.89; 1.6–2.23; P < 0.001), acute heart failure exacerbation (aOR 5.01; 3.54–7.1; P < 0.001), cardiogenic shock (aOR 7.73; 3.17–18.8; P < 0.001), and acute respiratory failure (aOR 3.24; 2.56–4.1; P < 0.001) as well as higher mean length of stay (LOS) (+2.67; 1.79–3.55; P < 0.001) and cost of care (+67 529; 36 630–98 427; P < 0.001). Conclusion Among patients undergoing HSCT, AF was independently associated with poor in-hospital outcomes, higher LOS, and cost of care.

AbstractIntroductionMost patients undergoing a left atrial appendage occlusion (LAAO) procedure are admitted for overnight observation. A same‐day discharge strategy offers the opportunity to improve resource utilization without compromising patient safety. We compared the patient safety outcomes and post‐discharge complications between same‐day discharge versus hospital admission (HA) (>1 day) in patients undergoing LAAO procedure.MethodsA systematic search of MEDLINE and Embase was conducted. Outcomes of interest included peri‐procedural complications, re‐admissions, discharge complications including major bleeding and vascular complications, ischemic stroke, all‐cause mortality, and peri‐device leak >5 mm. Mantel–Haenszel risk ratios (RRs) with 95% CIs were calculated.ResultsA total of seven observational studies met the inclusion criteria. There was no statistically significant difference between same‐day discharge versus HA regarding readmission (RR: 0.61; 95% confidence interval [CI]: [0.29–1.31]; p = .21), ischemic stroke after discharge (RR: 1.16; 95% CI: [0.49–2.73]), peri‐device leak >5 mm (RR: 1.27; 95% CI: [0.42–3.85], and all‐cause mortality (RR: 0.60; 95% CI: [0.36–1.02]). The same‐day discharge study group had significantly lower major bleeding or vascular complications (RR: 0.71; 95% CI: [0.54–0.94]).ConclusionsThis meta‐analysis of seven observational studies showed no significant difference in patient safety outcomes and post‐discharge complications between same‐day discharge versus HA. These findings provide a solid basis to perform a randomized control trial to eliminate any potential confounders.

AbstractBackgroundRepresentation trends of women, older adults, and ethnic/racial minorities in randomized controlled trials (RCTs) of atrial fibrillation (AF) are uncertain.MethodsWe systematically reviewed 134 AF related RCTs (phase II and III) encompassing 149,162 participants using Medline and ClinicalTrials.gov through April 2019 to determine representation trends of women, older patients (≥75 years), and ethnic/racial minorities. Weighted data on the prevalence of AF from epidemiological studies were used to compare the representation of the studied groups of interest in AF RCTs to their expected burden of the disease.ResultsOnly 18.7% of the RCTs reported proportion of older patients, and 12.7% RCTs reported ethnic/racial minorities. The proportions of women in RCTs versus general population were 35.2% and 35.1%, of Hispanics were 11.9% and 5.2%, of Blacks were 1.2% and 5.7%, of American Indian/Alaskans were 0.2% and 0.2%, of Asians were 14.2% and 2.4%, of native Hawaiian/Pacific Islanders were 0.05% and 0.1% and of non‐Whites were 19.5% and 22.5%, respectively. The weighted mean age (SD) across the trials was 65.3 (3.2) years which was less than the corresponding weighted mean age of 71.1 (4.5) years in the comparative epidemiological data.ConclusionThe reporting of older patients and ethnic/racial minorities was poor in RCTs of AF. The representation of women and American Indian/Alaskan natives matched their expected population share of disease burden. Hispanics and Asians were over‐represented and Blacks, native Hawaiian/Pacific Islanders and non‐Whites were under‐represented in RCTs of AF.

AbstractObjectives and BackgroundThere is insufficient current evidence about whether sex impacts outcomes of percutaneous left atrial appendage occlusion (LAAO). The aim of this study was to investigate the association between sex and short‐term outcomes of LAAO.MethodsPatients who were hospitalized and underwent LAAO from October 2015 to December 2017 in the National Readmission Database were queried. The primary endpoint of interest was major in‐hospital adverse events. Secondary endpoints included, 30‐day readmission rate, nonhome discharge, and cost of hospitalization. Propensity score matching (1:1) was performed to compare the outcomes among women and men.ResultsA total of 9,281 patients were included in the current analysis [women = 3,659 (39%); men = 5,622 (61%)]. Comparing women to men, women had lower prevalence of diabetes mellitus (30.6% vs 35.7%, p < .01), heart failure (28.6% vs 30.8%, p = .03), vascular disease (55.5% vs 69.6%, p < .01) and renal failure (18.3% vs 21.2%, p < .01), and higher CHA2DS2VASc score (5 [IQR4‐6] vs 4 [IQR3‐6], p < .01). After propensity‐score matching, women had higher rate of major in‐hospital adverse events (2.8% vs 1.9%; p < .01), and nonhome discharges (11.4% vs 6.7%; p < .01). Additionally, 30‐day readmission rate was higher among women (10% vs 8.6%, p = .03).ConclusionAmong hospitalized patients undergoing LAAO, women carry higher risk for major in‐hospital adverse events, nonhome discharge, and 30‐day readmission rates.

Background: Representation trends of women, older adults, and ethnic/racial minorities in randomized controlled trials (RCTs) of atrial fibrillation (AF) are uncertain. Methods: We systematically reviewed 134 AF related RCTs (phase II and III) encompassing 149,162 participants using Medline and ClinicalTrials.gov through April 2019 to determine representation trends of women, older patients (≥ 75 years), and ethnic/racial minorities. Weighted data on the prevalence of AF from epidemiological studies were used to compare the representation of the studied groups of interest in AF RCTs to their expected burden of the disease. Results: Only 18.7% of the RCTs reported proportion of older patients, and 12.7% RCTs reported ethnic/racial minorities. In RCTs, proportions of women, Hispanics, Blacks, American Indian/Alaskan patients, Asians, native Hawaiian/Pacific Islanders and non-Whites were 35.2%, 11.9%, 1.2%, 0.2%, 14.2%, 0.05%, and 19.5%, respectively. The corresponding proportions in general population were 35.1%, 5.2%, 5.7%, 0.2%, 2.4%, 0.1%, and 22.5%, respectively. The weighted mean age (SD) across the trials was 65.3 (3.2) years which was less than the corresponding weighted mean age of 71.1 (4.5) years in the comparative epidemiological data. Conclusion: The reporting of older patients and ethnic/racial minorities was poor in RCTs of AF. The representation of women and American Indian/Alaskan natives matched their expected population share of disease burden. Hispanics and Asians were over-represented and Blacks, native Hawaiian/Pacific Islanders and non-Whites were under-represented in RCTs of AF. In nearly all studied RCTs, the reporting of racial demographics did not start until later part of last decade.
