Background Reducing hospital readmissions has attracted attention from many stakeholders. However, the characteristics of 30-day readmissions after asthma-related hospital admissions in adults are ...not known. It is also unclear whether older adults are at higher risk of 30-day readmission. Objectives To investigate the rate, timing, and principal diagnosis of 30-day readmissions in adults with asthma and to determine age-related differences. Methods Retrospective cohort study of adults hospitalized for asthma exacerbation using the population-based inpatient samples of three states (California, Florida, and Nebraska) from 2005 through 2011. Patients were categorized into three age groups: younger (18-39 years), middle aged (40-64 years), and older (≥ 65 years) adults. Outcomes were 30-day all-cause readmission rate, timing, and principal diagnosis of readmission. Results Of 301,164 asthma-related admissions at risk for 30-day readmission, readmission rate was 14.5%. Compared with younger adults, older adults had significantly higher readmission rates (10.1% vs 16.5%; OR, 2.15 95% CI, 2.07-2.23; P < .001). The higher rate attenuated with adjustment (OR, 1.19 95% CI, 1.13-1.26; P < .001), indicating that most of the age-related difference is explained by sociodemographics and comorbidities. For all age groups, readmission rate was highest in the first week after discharge and declined thereafter. Overall, only 47.1% of readmissions were assigned respiratory diagnoses (asthma, COPD, pneumonia, and respiratory failure). Older adults were more likely to present with nonrespiratory diagnoses (41.7% vs 53.8%; P < .001). Conclusions After asthma-related admission, 14.5% of patients had 30-day readmission with wide range of principal diagnoses. Compared with younger adults, older adults had higher 30-day readmission rates and proportions of nonrespiratory diagnoses.
Background Research on nonsurgical weight loss interventions has failed to demonstrate consistent efficacy on asthma control, although these interventions resulted in only modest weight reductions. ...Objective We sought to test the hypothesis that bariatric surgery is associated with a rapid and sustained decrease in risk of asthma exacerbation. Methods We performed a self-controlled case series study of 2261 obese patients with asthma aged 18 to 54 years who underwent bariatric surgery using the population-based emergency department (ED) and inpatient sample in 3 states (California, Florida, and Nebraska). The primary outcome was an ED visit or hospitalization for asthma exacerbation from 2005 through 2011. We used conditional logistic regression to compare each patient's risk of the outcome event during sequential 12-month periods using presurgery months 13 to 24 as the reference period. Results During the reference period, 22.0% (95% CI, 20.3% to 23.7%) of patients had an ED visit or hospitalization for asthma exacerbation. In the subsequent 12-month presurgery period, the risk did not materially change (21.7%; 95% CI, 20.0% to 23.4%), with an odds ratio (OR) of 0.98 (95% CI, 0.85-1.13) compared with the reference period. By contrast, significantly fewer ED visits or hospitalizations for asthma exacerbation occurred within 12 months after bariatric surgery (10.9%; 95% CI, 9.6% to 12.2%), corresponding to an OR of 0.42 (95% CI, 0.35-0.50). Similarly, in the subsequent period of 13 to 24 months after bariatric surgery, the risk remained significantly lower (10.9%; 95% CI, 9.6% to 12.2%), corresponding to an OR of 0.42 (95% CI, 0.35-0.50). Conclusion In obese patients the risk of an ED visit or hospitalization for asthma exacerbation decreased by half after bariatric surgery. This reduction suggests the effectiveness of significant weight loss on asthma morbidity.

To evaluate the rate of emergency department (ED) visits for opioid overdose and to examine whether frequent ED visits for opioid overdose are associated with more hospitalizations, near-fatal ...events, and health care spending.
Retrospective cohort study of adults with at least 1 ED visit for opioid overdose between January 1, 2010, and December 31, 2011, derived from population-based data of State Emergency Department Databases and State Inpatient Databases for 2 large and diverse states: California and Florida. Main outcome measures were hospitalizations for opioid overdose, near-fatal events (overdose involving mechanical ventilation), and hospital charges during the year after the first ED visit.
The analytic cohort comprised 19,831 unique patients with 21,609 ED visits for opioid overdose. During a 1-year period, 7% (95% CI, 7%-7%; n=1389 patients) of the patients had frequent (2 or more) ED visits, accounting for 15% (95% CI, 14%-15%; n=3167) of all opioid overdose ED visits. Middle age, male sex, public insurance, lower household income, and comorbidities (such as chronic pulmonary disease and neurological diseases) were associated with frequent ED visits (all P<.01). Overall, 53% (95% CI, 52%-54%; n=11,412) of the ED visits for opioid overdose resulted in hospitalizations; patients with frequent ED visits for opioid overdose had a higher likelihood of hospitalization (adjusted odds ratio, 3.98; 95% CI, 3.38-4.69). In addition, 10.0% (95% CI, 10%-10%; n=2161) of the ED visits led to near-fatal events; patients with frequent ED visits had a higher likelihood of a near-fatal event (adjusted odds ratio, 2.27; 95% CI, 1.96-2.66). Total charges in Florida were $208 million (95% CI, $200-$219 million).
In this population-based cohort, we found that frequent ED visits for opioid overdose were associated with a higher likelihood of future hospitalizations and near-fatal events.
Objective To examine temporal trends in the US incidence of childhood asthma hospitalizations, in-hospital mortality, mechanical ventilation use, and hospital charges between 2000 and 2009. Study ...design This was a serial, cross-sectional analysis of a nationally representative sample of children hospitalized with acute asthma. The Kids Inpatient Database was used to identify children aged <18 years with asthma by International Classification of Diseases, Ninth Revision, Clinical Modification code 493.xx. Outcome measures were asthma hospitalization incidence, in-hospital mortality, mechanical ventilation use, and hospital charges. We examined temporal trends of each outcome, accounting for sampling weights. Hospital charges were adjusted for inflation to 2009 US dollars. Results The 4 separate years (2000, 2003, 2006, and 2009) of national discharge data included a total of 592 805 weighted discharges with asthma. Between 2000 and 2009, the rate of asthma hospitalization in US children decreased from 21.1 to 18.4 per 10 000 person-years (13% decrease; Ptrend < .001). Mortality declined significantly after adjusting for confounders (OR for comparison of 2009 with 2000, 0.37; 95% CI, 0.17-0.79). In contrast, there was an increase in the use of mechanical ventilation (from 0.8% to 1.0%, a 28% increase; Ptrend < .001). Nationwide hospital charges also increased from $1.27 billion to $1.59 billion (26% increase; Ptrend < .001); this increase was driven by a rise in the geometric mean of hospital charges per discharge, from $5940 to $8410 (42% increase; Ptrend < .001). Conclusion Between 2000 and 2009, we found significant declines in asthma hospitalization and in-hospital mortality among US children. In contrast, mechanical ventilation use and hospital charges for asthma increased significantly over this same period.

Little is known about the quality of acute asthma care in emergency departments (EDs) outside of North America.
We evaluated concordance of acute asthma management in Japanese EDs with ...recommendations in the 2007 National Institutes of Health asthma guidelines and investigated whether guideline concordance was associated with risk of hospital admission.
We conducted a multicenter chart review study in 23 EDs across Japan. We identified ED patients aged 18 to 54 years with acute asthma between 2009 and 2011. Concordance with evidence-based guideline recommendations was evaluated by using item-by-item quality measures and composite concordance scores both at patient and ED levels. These scores ranged from 0 to 100.
Among 1380 patients, the median age was 35 years and 11% were hospitalized. Overall guideline concordance score was suboptimal both at the patient level (mean ± SD, 72 ± 14) and ED level (mean ± SD, 72 ± 6). Specifically, asthma care at the patient level was suboptimal in several areas: inhaled anticholinergics in ED (2%), systemic corticosteroid in ED (56%) and at discharge (36%), and peak flow assessment (9%). A multivariable model that adjusted for severity at presentation and several ED characteristics showed that higher guideline concordance was associated with significantly lower risk of hospital admission (odds ratio, 0.70 per 10-unit increase in composite score; 95% CI, 0.62-0.79 per 10-unit increase in composite score).
The management of acute asthma in Japanese EDs is suboptimal. Greater concordance with guideline-recommended management might reduce unnecessary hospitalizations. Knowledge translation initiatives are warranted to increase adherence with best practice in acute asthma management.
Abstract Background The United States is battling obesity and heart failure (HF) epidemics. Although studies have suggested relationships between obesity and HF morbidity, little is known regarding ...the effects of substantial weight reduction in obese patients with HF. Objectives This study investigated whether bariatric surgery is associated with a decreased rate of HF exacerbation. Methods We performed a self-controlled case series study of obese patients with HF who underwent bariatric surgery, using the population-based emergency department (ED) and inpatient sample in California, Florida, and Nebraska. Primary outcome was ED visit or hospitalization for HF exacerbation from 2005 to 2011. We used conditional logistic regression to compare the outcome event rate during sequential 12-month periods, using pre-surgery months 13 to 24 as the reference period. Results We identified 524 patients with HF who underwent bariatric surgery. During the reference period, 16.2% of patients had an ED visit or hospitalization for HF exacerbation. The rate remained unchanged in the subsequent 12-month pre-surgery period (15.3%; p = 0.67). In the first 12-month period after bariatric surgery, we observed a nonsignificantly reduced rate (12.0%; p = 0.052). However, the rate was significantly lower in the subsequent 13 to 24 months after bariatric surgery (9.9%; adjusted odds ratio: 0.57; p = 0.003). By contrast, there was no significant reduction in the rate of HF exacerbation among obese patients who underwent nonbariatric surgery (i.e., cholecystectomy, hysterectomy). Conclusions Our findings indicate that bariatric surgery is associated with a decline in the rate of HF exacerbation requiring ED evaluation or hospitalization among obese patients with HF.

Objective: We sought to examine whether the outcomes of patients who receive a surgical procedure on Friday the 13th differ from patients who receive surgery on flanking Fridays. Background: Numerous ...studies have demonstrated that increased anxiety from the provider or patient around the time of surgery can lead to worse outcomes. Superstitious patients often express significant concern and anxiety when undergoing a surgical procedure on Friday the 13th. Methods: A retrospective, population-based cohort study of 19,747 adults undergoing 1 of 25 common surgical procedures on Friday the 13th or flanking control Fridays (Friday the 6th and Friday the 20th) between January 1, 2007, and December 31, 2019, with 1 year of follow-up. The main outcomes included death, readmission, and complications at 30 days (short-term), 90 days (intermediate-term), and 1 year (long-term). Results: A total of 7,349 (37.2%) underwent surgery on Friday the 13th, and 12,398 (62.8%) underwent surgery on a flanking Friday during the study period. Patient characteristics were similar between the 2 groups. We found no evidence that patients receiving surgery on Friday the 13th group were more likely to experience the composite primary outcome at 30 days adjusted odds ratio (aOR) = 1.02 (95% CI = 0.94–1.09), 90 days aOR = 0.97 (95% CI = 0.90–1.04), and 1 year aOR = 0.99 (95% CI = 0.94–1.04) after surgery. Conclusion: Patients receiving surgery on Friday the 13th do not appear to fare worse than those treated on ordinary Fridays with respect to the composite outcome.
Background It remains unclear whether the quality of acute asthma care in US emergency departments (EDs) has improved over time. Objectives We investigated changes in concordance of ED asthma care ...with 2007 National Institutes of Health guidelines, identified ED characteristics predictive of concordance, and tested whether higher concordance was associated with lower risk of hospitalization. Methods We performed chart reviews in ED patients aged 18 to 54 years with asthma exacerbations in 48 EDs during 2 time periods: 1997-2001 (2 prior studies) and 2011-2012 (new study). Concordance with guideline recommendations was evaluated by using item-by-item quality measures and composite concordance scores at the patient and ED levels; these scores ranged from 0 to 100. Results The analytic cohort comprised 4039 patients (2119 from 1997-2001 vs 1920 from 2011-2012). Over these 16 years, emergency asthma care became more concordant with level A recommendations at both the patient and ED levels (both P < .001). By contrast, concordance with non–level A recommendations (peak expiratory flow measurement and timeliness) decreased at both the patient (median score, 75 interquartile range, 50-100 to 50 interquartile range, 33-75, P < .001) and ED (mean score, 67 SD, 7 to 50 SD, 16, P < .001) levels. Multivariable analysis demonstrated ED concordance was lower in Southern and Western EDs compared with Midwestern EDs. After adjusting for severity, guideline-concordant care was associated with lower risk of hospitalization (odds ratio, 0.37; 95% CI, 0.26-0.53). Conclusions Between 1997 and 2012, we observed changes in the quality of emergency asthma care that differed by level of guideline recommendation and substantial interhospital and geographic variations. Greater concordance with guideline-recommended management might reduce unnecessary hospitalizations.

Background Little is known about the longitudinal change in the quality of acute asthma care for hospitalized children and adults in the United States. We investigated whether the concordance of ...inpatient asthma care with the national guidelines improved over time, identified hospital characteristics predictive of guideline concordance, and determined whether guideline-concordant care is associated with a shorter hospital length of stay (LOS). Methods This study was an analysis of data from two multicenter chart review studies of hospitalized patients aged 2 to 54 years with acute asthma during two time periods: 1999-2000 and 2012-2013. Outcomes were guideline concordance at the patient and hospital levels, and association of patient composite concordance with hospital LOS. Results The analytic cohort for the comparison of guideline concordance comprised 1,634 patients: 834 patients from 1999-2000 vs 800 patients from 2012-2013. Over these 15 years, inpatient asthma care became more concordant at the hospital-level, with the mean composite score increasing from 74 to 82 ( P < .001). However, during 2012-2013, wide variability in guideline concordance of acute asthma care remained across hospitals, with the greatest variation in provision of individualized written action plan at discharge (SD, 36). Guideline concordance was significantly lower in Midwestern and Southern hospitals compared with Northeastern hospitals. After adjusting for severity, patients who received care perfectly concordant with the guidelines had significantly shorter hospital LOS (–14% 95% CI, –23 to –4; P = .009). Conclusions Between 1999 and 2013, the guideline concordance of acute asthma care for hospitalized patients improved. However, interhospital variability remains substantial. Greater concordance with evidence-based guidelines was associated with a shorter hospital LOS.
