Trends in bronchiolitis hospitalizations in the United States, 2000-2009.

ABSTRACT:

Objective

To examine temporal trend in the national incidence of bronchiolitis hospitalizations, use of mechanical ventilation, and hospital charges between 2000 and 2009.

Methods

We performed a serial, cross-sectional analysis of a nationally representative sample of children hospitalized with bronchiolitis. The Kids Inpatient Database was used to identify children <2 years of age with bronchiolitis by International Classification of Diseases, Ninth Revision, Clinical Modification code 466.1. Primary outcome measures were incidence of bronchiolitis hospitalizations, mechanical ventilation (noninvasive or invasive) use, and hospital charges. Temporal trends were evaluated accounting for sampling weights.

Results

The 4 separated years (2000, 2003, 2006, and 2009) of national discharge data included 544?828 weighted discharges with bronchiolitis. Between 2000 and 2009, the incidence of bronchiolitis hospitalization decreased from 17.9 to 14.9 per 1000 person-years among all US children aged <2 years (17% decrease; P(trend) < .001). By contrast, there was an increase in children with high-risk medical conditions (5.9%-7.9%; 34% increase; P(trend) < .001) and use of mechanical ventilation (1.9%-2.3%; 21% increase; P(trend) = .008). Nationwide hospital charges increased from $1.34 billion to $1.73 billion (30% increase; P(trend) < .001); this increase was driven by a rise in the geometric mean of hospital charges per case from $6380 to $8530 (34% increase; P(trend) < .001).

Conclusions

Between 2000 and 2009, we found a significant decline in bronchiolitis hospitalizations among US children. By contrast, use of mechanical ventilation and hospital charges for bronchiolitis significantly increased over this same period.

Project description:BackgroundCardiac arrhythmias are associated with increased maternal morbidity. There are limited data on trends of arrhythmias among women hospitalized for delivery.Materials and methodsWe used the National Inpatient Sample (NIS) database to identify delivery hospitalizations for individuals aged 18-49 years between 2009 to 2019 and utilized coding data from the 9th and 10th editions of the International Classification of Diseases to identify supraventricular tachycardias (SVT), atrial fibrillation (AF), atrial flutter, ventricular tachycardia (VT), and ventricular fibrillation (VF). Arrhythmia trends were analyzed by age, race-ethnicity, hospital setting, and hospital geographic regions. Multivariable logistic regression was used to evaluate the association of demographic, clinical, and socioeconomic characteristics with arrhythmias.ResultsAmong 41,576,442 delivery hospitalizations, the most common arrhythmia was SVT (53%), followed by AF (31%) and VT (13%). The prevalence of arrhythmia among delivery hospitalizations increased between 2009 and 2019. Age > 35 years and Black race were associated with a higher arrhythmia burden. Factors associated with an increased risk of arrhythmias included valvular disease (OR: 12.77; 95% C1:1.98-13.61), heart failure (OR:7.13; 95% CI: 6.49-7.83), prior myocardial infarction (OR: 5.41, 95% CI: 4.01-7.30), peripheral vascular disease (OR: 3.19, 95% CI: 2.51-4.06), hypertension (OR: 2.18; 95% CI: 2.07-2.28), and obesity (OR 1.69; 95% CI: 1.63-1.76). Delivery hospitalizations complicated by arrhythmias compared with those with no arrhythmias had a higher proportion of all-cause in-hospital mortality (0.95% vs. 0.01%), cardiogenic shock (0.48% vs. 0.00%), preeclampsia (6.96% vs. 3.58%), and preterm labor (2.95% vs. 2.41%) (all p < 0.0001).ConclusionPregnant individuals with age > 35 years, obesity, hypertension, valvular heart disease, or severe pulmonary disease are more likely to have an arrhythmia history or an arrhythmia during a delivery hospitalization. Delivery hospitalizations with a history of arrhythmia are more likely to be complicated by all-cause in-hospital mortality, cardiovascular, and adverse pregnancy outcomes (APOs). These data highlight the increased risk associated with pregnancies among individuals with arrhythmias.
