To evaluate whether delirium during pediatric critical illness is associated with post-discharge health-related quality of life. DESIGN: Retrospective cohort study. SETTING: Academic tertiary care center. PATIENTS: Children 1 month to 18 years old admitted to the PICU or cardiac ICU and enrolled in the Seattle Children's Hospital Outcomes Assessment Program. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS:Delirium was assessed twice daily using the Cornell Assessment of Pediatric Delirium; a score greater than or equal to 9 (with fluctuating level of arousal for children with developmental disability) indicated delirium. Baseline (pre-admission) and post-discharge health-related quality of life were assessed by the Pediatric Quality of Life Inventory (Mapi Research Trust, Lyon, France) or the Functional Status II-R (for children with developmental disability). Among 534 patients, delirium was common (44%), as was clinically important decline in health-related quality of life (≥ 4.5 points) from baseline to follow-up (22%), measured at median 6.6 weeks post-hospital discharge (interquartile range, 5.1-8.5). On univariate analysis, children with delirium had similar likelihood of health-related quality of life decline compared with those without (25.5% vs 19.7%; p = 0.1). Using multivariable logistic regression adjusting for age, medical complexity, predicted risk of mortality, admission diagnosis, receipt of noninvasive ventilation, hospital length of stay, time to follow-up, and parent age, delirium was independently associated with health-related quality of life decline among children assessed by the Pediatric Quality of Life Inventory (adjusted odds ratio, 2.0; 95% CI, 1.1-3.5). Among children evaluated with the Functional Status II-R, delirium was not independently associated with health-related quality of life decline (odds ratio, 1.4; 95% CI, 0.6-3.2). In both groups, longer time to follow-up was also independently associated with improvements in health-related quality of life.CONCLUSIONS: Delirium during the ICU stay is associated with decline in health-related quality of life from baseline to post-discharge follow-up among children assessed by the Pediatric Quality of Life Inventory, who were generally characterized by normal baseline cognitive function and less medical comorbidity. This association was not present among children assessed by the Functional Status II-R, potentially due to their higher overall risk of health-related quality of life decline, or other clinical differences that modify the effects of delirium in this group. KEY WORDS: critical care outcomes; delirium; developmental disabilities; follow-up studies; health-related quality of life; intensive care units, pediatric C hildren surviving critical illness commonly experience new morbidity following the ICU stay (1, 2). Post-ICU morbidity is multifaceted, including effects on physical, cognitive, and psychosocial functioning (3, 4). These effects are important to both patients and clinicians
Background Ongoing measures to improve pediatric continuous kidney replacement therapy (CKRT) have lowered mortality rates, shifting the focus to survivor functional status. While septic acute kidney injury generates new morbidity in pediatric critically ill patients, acquired morbidities and functional status of CKRT population are unknown. We predicted that CKRT survivors are at risk for new morbidity and would have worse functional status at PICU discharge compared to baseline, and aimed to describe associated factors. Methods Retrospective cohort study over 24 months of CKRT patients surviving to PICU discharge in a quaternary children’s hospital. Functional outcome was determined by Functional Status Scale (FSS). Results FSS scores were higher at PICU and hospital discharge compared to baseline. Of 45 CKRT survivors, 31 (69%) had worse FSS score at PICU discharge and 51% had new morbidity (≥3 increase in FSS); majority qualified as moderate to severe disability (FSS ≥10). Four patients (9%) had new tracheostomy, 3 (7%) were ventilator dependent, and 10 (22%) were dialysis dependent. Most (23/45, 51%) required outpatient rehabilitation. Cumulative days on sedation, controlled for illness severity, were independently associated with worse FSS at PICU discharge (aOR 25.18 (3.73, 169.92)). In adjusted analyses, duration of sedation was associated with new morbidity, while neurologic comorbidity, percent fluid overload at CKRT start, and nonrenal comorbidity were associated with moderate to severe disability at PICU discharge when controlled for baseline FSS. Conclusions CKRT survivors, with new morbidity and worse functional outcomes at PICU discharge, are a newly described vulnerable population requiring targeted follow-up. Deliberate decrease of sedation exposure in patients with decreased clearance due to organ dysfunction needs to be studied as a modifiable risk factor.
