Background: Readmissions after in-hospital cardiopulmonary resuscitation (ICPR) are common and contribute to increased health care utilization and costs. This study aimed to estimate the burden and patterns of 30-day readmission after ICPR from the US Nationwide Readmission Database (NRD).Methods: Using International Classification of Diseases-Ninth Revision-Clinical Modification codes, patients who underwent ICPR in the 2014 NRD were included. The incidence, predictors, causes, and costs of 30-day readmission were analyzed with discharge weights to obtain national estimates.Results: Among the 27,278 index admissions that survived to hospital discharge after ICPR, 5439 (20.0%) were readmitted within 30 days. Length of stay (LOS) ≥11 days during index hospitalization, chronic pulmonary disease, congestive heart failure, renal failure, discharge from the teaching metropolitan hospital, Medicare insurance, depression, and diabetes were independent predictors of 30-day readmission. The most common causes of readmission among the 5439 cases were sepsis (13.7%), heart failure (10.9%), and respiratory failure (6.4%). The estimated median costs of readmission were $10,498 (interquartile range, $5797-21,364), which accounted for 25.7% of the total episodes of care (index + readmission). The median LOS of readmission was 5 (3-9) days.Conclusions: Thirty-day readmissions after ICPR were associated with patient comorbidities and significant cost burden. Recognition of these predictors and individualization of care would allow for the provision of appropriate interventions, and reduce readmissions and healthcare costs. [ABSTRACT FROM AUTHOR]

Background: Atrial fibrillation (AF) is the most common arrhythmia in patients undergoing percutaneous coronary intervention (PCI)., Hypothesis: Large administrative data may provide further insight into temporal trends in the prevalence and burden of AF in patients who underwent PCI., Methods: Using the National Inpatient Sample database in the U.S., AF patients ≥18 years who underwent PCI between 2005 and 2014 and were identified by the International Classification of Diseases, ninth revision, Clinical Modification, were examined. In-hospital mortality, morbidity, resource use, and medical costs were evaluated in crude and propensity-matched analyses., Results: Among an estimated 6 272 232 hospitalizations, of patients undergoing PCI, AF prevalence was 9.9% and steadily increased from 8.6% to 12.0% between 2005 and 2014 (P < .001); there was also a greater proportion of comorbidities. There was a marked increase in AF prevalence among those aged ≥65 years and those undergoing elective PCIs. AF was independently associated with higher in-hospital mortality and higher rates of transient ischaemic attack/stroke, bleeding complications, and non-home discharge. Excessive in-hospital mortality, stroke rate, gastrointestinal bleeding, blood transfusion, length of stay, and costs among AF hospitalizations were consistently observed throughout the study period., Conclusion: AF becomes more prevalent in patients undergoing PCI, possibly due to a higher comorbidity, particularly in elderly patients with non-acute indications. Less favorable trends in mortality, bleeding, and stroke among AF patients who underwent PCI were consistent over time. Continuous efforts are needed to improve outcomes and manage strategies for AF patients undergoing PCI., (© 2019 The Authors. Clinical Cardiology published by Wiley Periodicals, Inc.)

Background The contemporary incidence of and reasons for early readmission after infective endocarditis ( IE ) are not well known. Therefore, we analyzed 30-day readmission demographics after IE from the US Nationwide Readmission Database. Methods and Results We examined the 2010 to 2014 Nationwide Readmission Database to identify index admissions for a primary diagnosis of IE with survival at discharge. Incidence, reasons, and independent predictors of 30-day unplanned readmissions were analyzed. In total, 11 217 patients (24.8%) were nonelectively readmitted within 30 days among the 45 214 index admissions discharged after IE . The most common causes of readmission were IE (20.5%), sepsis (8.7%), complications of device/graft (8.1%), and congestive heart failure (7.6%). In-hospital mortality and the valvular surgery rates during the readmissions were 8.1% and 9.1%, respectively. Discharge to home or self-care, undergoing valvular surgery, aged ≥60 years, and having private insurance were independently associated with lower rates of 30-day readmission. Length of stay of ≥10 days, congestive heart failure, diabetes mellitus, renal failure, chronic pulmonary disease, peripheral artery disease, and depression were associated with higher risk. The total hospital costs of readmission were $48.7 million per year (median, $11 267; interquartile range, $6021-$25 073), which accounted for 38.6% of the total episodes of care (index+readmission). Conclusions Almost 1 in 4 patients was readmitted within 30 days of admission for IE . The most common reasons were IE , other infectious causes, and cardiac causes. A multidisciplinary approach to determine the surgical indications and close monitoring are necessary to improve outcomes and reduce complications in in-hospital and postdischarge settings.
