When Duty Calls, Resident Physicians Answer: Learning to Take Transfer Calls.

BACKGROUND AND OBJECTIVE: Transitions of care are error-prone. Standardized handoffs at transitions improve safety. There are limited published curricula teaching residents to perform interfacility transfer calls or providing a framework for performance evaluation. The objective of this study was to measure the impact of a workshop utilizing a standardized handoff tool on resident-reported confidence in taking transfer calls and observed behavioral change in a simulated environment. METHODS: A pre- and posteducational intervention trial was performed at a large children's hospital in March 2021. A 1-hour session highlighting the importance of phone communication, outlining an evidence-based handoff tool, and reviewing cases was delivered to 44 of 75 residents who attended scheduled didactics. The workshop's effectiveness was measured by rating behavioral change in a simulated environment. Calls were scored by using a 0 to 24 summative score checklist created from the handoff tool. A paired t test was used to analyze the differences in pre- and postintervention scores. Resident confidence, knowledge of the call process, and perceived importance of skill were measured with an internally developed retrospective pre- and postsurvey. The survey results were analyzed with a Wilcoxon rank test and Kruskal-Wallis test. RESULTS: Behaviors in a simulated environment, measured by an average score on the grading checklist, had a mean score increase of 6.52 points (P <.0001). Of the participants, 95% completed the survey, which revealed that reported confidence, knowledge of the transfer call process, and importance of transfer call skills increased significantly (P <.0001). CONCLUSIONS: This workshop improved resident behaviors in a simulated environment, confidence, and knowledge of the transfer call process, demonstrating the utility of providing a standardized tool and education to improve transitions of care.

Ion track etching of polycarbonate membranes monitored by in situ small angle X-ray scattering.

In situ small angle X-ray scattering (SAXS) measurements of ion track etching in polycarbonate foils are used to directly monitor the selective dissolution of ion tracks with high precision, including the early stages of etching. Detailed information about the track etching kinetics and size, shape, and size distribution of an ensemble of nanopores is obtained. Time resolved measurements as a function of temperature and etchant concentration show that the pore radius increases almost linearly with time for all conditions and the etching process can be described by an Arrhenius law. The radial etching shows a power law dependency on the etchant concentration. An increase in the etch rate with increasing temperature or concentration of the etchant reduces the penetration of the etchant into the polymer but does not affect the pore size distribution. The in situ measurements provide an estimate for the track etch rate, which is found to be approximately three orders of magnitude higher than the radial etch rate. The measurement methodology enables new experiments studying membrane fabrication and performance in liquid environments.

Recurrent Coarctation After Neonatal Univentricular and Biventricular Norwood-Type Arch Reconstruction.

BACKGROUND: Previous studies have evaluated recurrent coarctation after the Norwood procedure (NP) in patients with single-ventricle (SV) anatomy. Extended patch augmentation of the aorta, a Norwood-type arch reconstruction (NTAR), is also used in patients with 2 ventricles and a diffusely hypoplastic arch; however, outcomes after NTAR in these patients are not well described. METHODS: A retrospective review was performed of neonates with SV and 2-ventricle (2V) anatomy who underwent an NP or NTAR at our institution from 2000 to 2010. The incidence of recurrent coarctation requiring intervention and associated risk factors were evaluated. RESULTS: Overall, 101 patients with 2V anatomy and 361 patients with SV anatomy were included. Eighteen patients with 2V anatomy (17.8%) and 35 patients with SV anatomy (9.7%) required intervention for recurrent coarctation at a median of 0.5 years (interquartile range [IQR], 0.3-1.2 years) after the initial operation. Independent risk factors associated with recurrent coarctation in patients with 2V anatomy included weight less than 2.5 kg (hazard ratio [HR], 6.05; p = 0.001) and peak aortic arch gradient (PAAG) on the discharge echocardiogram greater than 10 mm Hg (HR, 3.07; p = 0.03). In patients with SV anatomy, shunt type (HR, 6.42; p < 0.0001 for right ventricle to pulmonary artery [RV-PA] shunt compared with others) and peak gradient on the discharge echocardiogram greater than 10 mm Hg were found to be significant (HR, 7.40; p < 0.0001). There was no survival difference in patients with and those without recurrent coarctation. CONCLUSIONS: Recurrent coarctation is common after NTAR. Small patient size and shunt type were found to be independent risk factors for recurrent coarctation in the 2V and SV populations, respectively, and discharge aortic arch gradient was a significant risk factor in both populations.

Risk of suicidal ideation in adolescents with both self-asphyxial risk-taking behavior and non-suicidal self-injury.

This study examined adolescent participation in self-asphyxial risk-taking behaviors (SAB), sometimes known as the "choking game," and its relationship with other adolescent risk behaviors, including non-suicidal self-injury (NSSI). Researchers proposed that participation in SAB and NSSI would be associated with suicidal behavior, disordered eating, and substance use. Using a large community-based sample, results revealed preliminary associations between SAB and other risk-taking behaviors. Adolescents who had engaged in both SAB and NSSI reported more concurrent risk behaviors than adolescents who participated in only one of the behaviors or neither behavior. Results indicate that greater awareness of SAB is important, and continued research can evaluate the possible link between the behavior and risk for suicide.
