Family Presence at the PICU Bedside and Pediatric Patient Delirium: Retrospective Analysis of a Single-Center Cohort, 2014–2017

OBJECTIVES: To examine the association between family presence at the PICU bedside and daily positive delirium screening scores. DESIGN: Retrospective cohort study. SETTING: Tertiary children's hospital PICU. SUBJECTS: Children younger than 18 years old with PICU length of stay greater than 36 hours enrolled in the Seattle Children's Hospital Outcomes Assessment Program from 2014 to 2017. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: In the dataset, delirium screening had been performed bid using the Cornell Assessment of Pediatric Delirium, with scores greater than or equal to 9 classified as positive. Family presence was documented every 2 hours. Among 224 patients, 55% ( n = 124/224) had positive delirium screening on 44% ( n = 408/930) of PICU days. Family presence at the bedside during PICU stay (< 90% compared with ≥ 90%) was associated with higher proportion of ever (as opposed to never) being screened positive for delirium (26/37 vs. 98/187; difference, 17.9% 95% CI, 0.4-32.1%; p = 0.046). On univariate analysis, each additional decile of increasing family presence was associated with lower odds of positive delirium screening on the same day (odds ratio OR, 0.87 95% CI, 0.77-0.97) and subsequent day (OR, 0.84 95% CI, 0.75-0.94). On multivariable analysis after adjustments, including baseline Pediatric Cerebral Performance Category (PCPC), higher family presence was associated with lower odds of subsequent-day positive delirium screening (OR, 0.89 95% CI, 0.81-0.98). Among patients with PCPC less than or equal to 2, each additional decile of increasing family presence was independently associated with lower odds of both same-day (OR, 0.90 95% CI, 0.81-0.99) and subsequent-day (OR, 0.85 95% CI, 0.76-0.95) positive delirium screening. CONCLUSIONS: In our 2014-2017 retrospective cohort, greater family presence was associated with lower odds of delirium in PICU patients. Family presence is a modifiable factor that may mitigate the burden of pediatric delirium, and future studies should explore barriers and facilitators of family presence in the PICU.
