Inpatient Hospital Factors and Resident Time With Patients and Families.

OBJECTIVES: To define hospital factors associated with proportion of time spent by pediatric residents in direct patient care. METHODS: We assessed 6222 hours of time-motion observations from a representative sample of 483 pediatric-resident physicians delivering inpatient care across 9 pediatric institutions. The primary outcome was percentage of direct patient care time (DPCT) during a single observation session (710 sessions). We used one-way analysis of variance to assess a significant difference in the mean percentage of DPCT between hospitals. We used the intraclass correlation coefficient analysis to determine within- versus between-hospital variations. We compared hospital characteristics of observation sessions with ≥12% DPCT to characteristics of sessions with <12% DPCT (12% is the DPCT in recent resident trainee time-motion studies). We conducted mixed-effects regression analysis to allow for clustering of sessions within hospitals and accounted for correlation of responses across hospital. RESULTS: Mean proportion of physician DPCT was 13.2% (SD = 8.6; range, 0.2%-49.5%). DPCT was significantly different between hospitals (P < .001). The intraclass correlation coefficient was 0.25, indicating more within-hospital than between-hospital variation. Observation sessions with ≥12% DPCT were more likely to occur at hospitals with Magnet designation (odds ratio [OR] = 3.45, P = .006), lower medical complexity (OR = 2.57, P = .04), and higher patient-to-trainee ratios (OR = 2.48, P = .05). CONCLUSIONS: On average, trainees spend <8 minutes per hour in DPCT. Variation exists in DPCT between hospitals. A less complex case mix, increased patient volume, and Magnet designation were independently associated with increased DPCT.

AKI in hospitalized children: epidemiology and clinical associations in a national cohort.

BACKGROUND AND OBJECTIVES: Although AKI is common among hospitalized children, comprehensive epidemiologic data are lacking. This study characterizes pediatric AKI across the United States and identifies AKI risk factors using high-content/high-throughput analytic techniques. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: For the cross-sectional analysis of the 2009 Kids Inpatient Database, AKI events were identified using International Classification of Diseases, Ninth Revision, Clinical Modification codes. Demographics, incident rates, and outcome data were analyzed and reported for the entire AKI cohort as well as AKI subsets. Statistical learning methods were applied to the highly imbalanced dataset to derive AKI-related risk factors. RESULTS: Of 2,644,263 children, 10,322 children developed AKI (3.9/1000 admissions). Although 19% of the AKI cohort was ≤ 1 month old, the highest incidence was seen in children 15-18 years old (6.6/1000 admissions); 49% of the AKI cohort was white, but AKI incidence was higher among African Americans (4.5 versus 3.8/1000 admissions). In-hospital mortality among patients with AKI was 15.3% but higher among children ≤ 1 month old (31.3% versus 10.1%, P<0.001) and children requiring critical care (32.8% versus 9.4%, P<0.001) or dialysis (27.1% versus 14.2%, P<0.001). Shock (odds ratio, 2.15; 95% confidence interval, 1.95 to 2.36), septicemia (odds ratio, 1.37; 95% confidence interval, 1.32 to 1.43), intubation/mechanical ventilation (odds ratio, 1.2; 95% confidence interval, 1.16 to 1.25), circulatory disease (odds ratio, 1.47; 95% confidence interval, 1.32 to 1.65), cardiac congenital anomalies (odds ratio, 1.2; 95% confidence interval, 1.13 to 1.23), and extracorporeal support (odds ratio, 2.58; 95% confidence interval, 2.04 to 3.26) were associated with AKI. CONCLUSIONS: AKI occurs in 3.9/1000 at-risk US pediatric hospitalizations. Mortality is highest among neonates and children requiring critical care or dialysis. Identified risk factors suggest that AKI occurs in association with systemic/multiorgan disease more commonly than primary renal disease.
