A Program of Assessment Model for Point-of-Care Ultrasound Training for Pediatric Critical Care Providers: A Comprehensive Approach to Enhance Competency-Based Point-of-Care Ultrasound Training.

Point-of-care ultrasound (POCUS) is increasingly accepted in pediatric critical care medicine as a tool for guiding the evaluation and treatment of patients. POCUS is a complex skill that requires user competency to ensure accuracy, reliability, and patient safety. A robust competency-based medical education (CBME) program ensures user competency and mitigates patient safety concerns. A programmatic assessment model provides a longitudinal, holistic, and multimodal approach to teaching, assessing, and evaluating learners. The authors propose a fit-for-purpose and modifiable CBME model that is adaptable for different institutions' resources and needs for any intended competency level. This educational model drives and supports learning, ensures competency attainment, and creates a clear pathway for POCUS education while enhancing patient care and safety.

Inter-Rater Reliability of Delirium Screening of Infants in the Cardiac ICU: A Prospective, Observational Study.

OBJECTIVES: To determine the inter-rater reliability (IRR) of the Cornell Assessment for Pediatric Delirium (CAP-D) in infants admitted to a cardiac ICU (CVICU) and to explore the impact of younger age and mechanical ventilation on IRR. DESIGN: Prospective cross-sectional study of delirium screening performed by bedside CVICU nurses. We collected data from September 2020 to April 2021. We evaluated IRR with intraclass correlation coefficient (ICC) one-way random effects and Fleiss kappa for multiple raters. SETTING: Eighteen-bed academic pediatric CVICU. PARTICIPANTS: Subjects: Infants 1 day to 1 year old admitted to the CVICU, stratified in two age groups (≤ 9 wk and 9 wk to < 1 yr). Exclusion criteria were patients' immediate postoperative day, State Behavioral Scale score less than or equal to -2, or at risk for hemodynamic instability with assessment. Raters: CVICU nurses working in the unit during study days. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Groups of four raters performed 91 assessments, a total of 364 CAP-D screens. Forty-five of 91 (49%) were in patients less than or equal to 9 weeks old and 43 of 91 (47%) in mechanically ventilated patients. Sixty-eight of 81 nurses (81%) participated. In infants less than or equal to 9 weeks old, ICC was 0.59 (95% CI 0.44-0.71), poor to moderate reliability, significantly lower than the ICC in infants greater than 9 weeks and 0.72 (95% CI 0.61-0.82), moderate to good reliability. In mechanically ventilated infants, ICC was 0.5 (95% CI 0.34-0.65), poor to moderate reliability, significantly lower than the ICC in nonmechanically ventilated infants and 0.69 (95% CI 0.57-0.8), moderate to good reliability. Fleiss kappa for all infants was 0.47 (95% CI 0.34-0.6), slight to fair agreement. Use of anchor points did not improve reliability. CONCLUSIONS: In the youngest, most vulnerable infants admitted to the CVICU, further evaluation of the CAP-D tool is needed.

Prophylactic Enoxaparin Against Catheter-Associated Thrombosis in Postoperative Cardiac Children: An Interrupted Time Series Analysis.

OBJECTIVES: The effectiveness of pharmacologic prophylaxis against catheter-associated thrombosis in children is unclear. We evaluated the compliance and outcomes associated with a prophylactic enoxaparin protocol in postoperative cardiac children. DESIGN: The protocol was implemented as a quality improvement initiative and then analyzed using interrupted time series method. Data collected from November 2014 to December 2018 were divided into preprotocol (period 1), protocol implementation (period 2), and protocol revision (period 3). SETTING: A 12-bed academic pediatric cardiac ICU. PATIENTS: Children less than or equal to 18 years old with congenital heart disease admitted postoperatively with central venous catheter in situ for greater than or equal to 1 day. INTERVENTIONS: Before 2016, prophylactic enoxaparin was administered according to physician preference. In January 2016, an enoxaparin protocol was implemented with a goal anti-Xa range of 0.25-0.49 international units/mL. Protocol was revised in February 2017 to increase the starting dose by 25% for infants less than 1 year old. MEASUREMENTS AND MAIN RESULTS: We analyzed 780 hospitalizations from 636 children. Median percentage of catheter-days on prophylactic enoxaparin was 33% (interquartile range [IQR], 23-47%), 42% (IQR, 30-51%), and 38% (IQR, 35-52%) in periods 1-3, respectively. Percentage of catheter-days on enoxaparin showed immediate increase of 90% (95% CI, 17-210%) between periods 1 and 2 and sustained increase of 2% (95% CI, 0.3-4%) between periods 2 and 3. Median rates of thrombosis per 1,000 catheter-days were 5.8 (IQR, 0-9.3), 3.8 (IQR, 0-12), and 0 (IQR, 0-5.3) in periods 1-3, respectively. Rate of thrombosis showed immediate decrease of 67% (95% CI, 12-87%) between periods 1 and 2 and sustained decrease of 11% (95% CI, 2-18%) between periods 1 and 3. CONCLUSIONS: The temporal association between increase in percentage of catheter-days on enoxaparin and decrease in rate of thrombosis suggests the effectiveness of prophylactic enoxaparin.
