A B S T R A C TOBJECTIVES: Children with medical complexity (CMC) are commonly assisted by medical devices to support essential body functions, although complications may lead to preventable emergency department (ED) and hospital use. Our objective was to identify predictors of device-complicated ED visits and hospitalizations.METHODS: This single-center retrospective cohort study included patients referred to a Pediatric Complex Care Program between April 1, 2014, and April 30, 2016, assisted by at least 1 medical device. Hospitalizations and ED visits in the year before enrollment were rated for likelihood for being due to device complications. Interrater reliability among 3 independent reviewers was assessed. Bivariate followed by multivariate logistic regression clustered by patient helped us identify associations between demographic, clinical, and device characteristics associated with device-complicated ED or hospital encounters. RESULTS:Interrater reliability was high (k 5 0.92). Among 98 CMC, device-complicated encounters represented 17% of 258 hospitalizations and 31% of 228 ED visits. Complications of 3 devices (central venous catheters, enteral tubes, and tracheostomy tubes) accounted for 13% of overall hospitalizations and 28% of overall ED visits. Central venous catheter presence (adjusted odds ratio [aOR] 3.2 [95% confidence interval (CI) 1.1-9.5]) was associated with device-complicated ED visits. Gastrojejunostomy/jejunostomy tube presence (aOR 3.3 [95% CI 1.5-7.5]) or tracheostomies with (aOR 8.1 [95% CI 2.3-28.5]) or without (aOR 4.5 [95% CI 1.7-7.5]) ventilator use was associated with device-complicated hospitalizations. Clinical variables were poor predictors of device-complicated encounters.CONCLUSIONS: Device-complicated ED visits and hospitalizations comprised a substantial proportion of total hospital and ED use. Developing interventions to prevent device complications may be a promising strategy to reduce overall CMC use.

Introduction: Medical device-related complications often lead to emergency department (ED) visits and hospitalizations for children with medical complexity (CMC), and pediatric complex care programs may be one way to decrease unnecessary encounters. Methods: A retrospective cohort study comparing ED and inpatient encounters due to device complications of 2 cohorts of CMC at a single children's hospital during 2014-2016; 99 enrolled in a complex care program and 244 in a propensity-matched comparison group. Structured chart reviews identified ED and inpatient encounters due to device complications. The outcome was a change in the frequency of these encounters from the year before to the year after enrollment in the hospital's complex care program. Program effects were estimated with weighted difference-in-differences (DiDs), comparing the change in mean encounter frequency for CMC enrolled in the program with change for propensity-matched children not enrolled in the program. Results: Mean encounters related to device complications decreased for both groups. Complication-related ED encounters per year decreased from a weighted mean (SD) of 0.74 (0.85) to 0.30 (0.44) in enrolled children and 0.26 (0.89) to 0.12 (0.56) in comparison children, a DiD of 0.30 fewer [95% confidence interval (CI) −0.01 to 0.60]. The largest reductions in device complication ED visits were among those with enteral tubes [0.36 fewer (95% CI 0.04-0.68)]. Hospitalizations decreased over time, but DiDs were not significantly different between groups. Conclusions: Acute care use from device complications decreased with time. Complex care program enrollment may be associated with more substantial reductions in device complication ED visits, and effects may be most pronounced for CMC with enteral tubes.
