Aims Cannabis is an increasingly common recreational substance used by teenagers. However, there is limited data probing association of cardiac arrhythmias with marijuana use in this population. Methods and Results We provide prevalence trends, disease burden and healthcare utilization of cardiac arrhythmias associated with cannabis use disorder (CUD) in hospitalized teenagers (13–20 years) using a large national administrative database in the United States from 2003–2016. We used partial least square regression analysis for assessing trends in prevalence of cardiac arrhythmias and multiple logistic regression to elucidate independent predictors of arrhythmias associated with CUD. Among all CUD related hospitalizations (n = 876, 431), 0.5% had arrhythmias. Prevalence trends of arrhythmias among CUD increased six-fold during the study period (P < 0.001). CUD was more prevalent in males and older teens (both P < 0.001). There was a significant risk for mortality when CUD was associated with arrhythmia (7.4% vs. 0.1%, P < 0.001). While mean length-of-stay (LOS) was shorter (4.4 vs. 5.4 days, P < 0.001) for patients with CUD, they incurred three times higher mean hospitalization charges when compared to CUD patients without arrhythmia ($45 959 vs. $18 986, P < 0.001). Both LOS and hospitalization charges showed an uptrend during the study period (P < 0.001). Congenital heart disease, congestive heart failure, hypertension, and obesity independently predicted arrhythmias in CUD while other substance abuse did not change the risk of arrhythmia in CUD. Conclusion Arrhythmia burden is increasing among teenagers with CUD, and co-occurrence of arrhythmia and CUD worsens hospital outcomes.

We sought to examine incidence and mortality trends of drowning-related hospitalizations in children aged <20 years and to study the presence of risk factors associated with in-hospital mortality. Retrospective analysis of the 2003-2016 Health Care Cost and Utilization Project National Inpatient Sample and Kids’ Inpatient Database was performed. The estimated annual incidence rate of drowning hospitalizations declined 31.5% from 2.73 to 1.87 per 100 000 population. Most drowning-related hospitalizations were seen in <5-year-old children (66.4%) and in males (65.3%), Caucasians (41.7%), and public insurance (46%). In-hospital mortality declined 46% from an estimated 290 deaths in 2003 to 156 deaths in 2016. On multivariate analysis, age <5 years, Caucasian ethnicity, uninsured status, pool/bathtub or undetermined location, arrhythmia (adjusted odds ratio [aOR] = 1.3, P = .001), acute kidney injury (aOR = 3.4, P < .001), cerebral edema (aOR = 2.8, P < .001), cardiopulmonary resuscitation (aOR = 12.1, P < .001), and invasive mechanical ventilation (aOR = 28.4, P < .001) were found to be independent predictors of mortality.

Objective: To evaluate the national trends in pediatric severe sepsis in the United States from 2003 to 2014. Study design: For this study, we included nonoverlapping years of Kids Inpatient database and National Inpatient Sample database while including hospitalizations of children between 1 and 20 years of age from more than 4200 hospitals across the United States. We identified patient hospitalizations with severe sepsis using specific ICD codes and modified Angus Criteria. Trend analysis of various factors associated with severe sepsis was calculated using the Cochrane–Armitage test. Associated foci of infection and comorbid conditions were identified using specific ICD codes, and a multivariate regression analysis with death as outcome variable was done to evaluate for in hospital predictors of mortality. Results: Totally, 109,026 episodes of severe sepsis were identified during the study period between 2003 and 2014. Incidence of severe sepsis hospitalizations increased by 2.5 times (0.64–1.57 per 10,000 population) over the study period with notable concurrent significant decrease in mortality by more than 50%. Lower age, African American, Hispanic ethnicity, complex neurologic conditions, infective endocarditis, immunodeficient states including primary immunodeficiency disorder, HIV, burns, malignancy and transplant status are associated with mortality. There is a significant increase in use of healthcare resources (P < 0.001) with mean charges of 94,966$ despite a notable decrease in mean length of stay (22 vs. 16 days, P < 0.001) over the study period. Conclusion: Incidence of pediatric severe sepsis is high leading to a significant use of healthcare resources. This study provides a detailed analysis of associated inpatient factors and comorbidities associated with mortality.
