In light of the recent studies, we will suggest that the interaction of visual and executive loops could strengthen or weaken learned associations following different reward values. Furthermore, we speculate that the overlap of the visual and executive loops can account for the switching between the associative vs. rule-based category learning systems.

In 2018, the ACGME (Accreditation Council for Graduate Medical Education) made a change to the maximum permissible number of consecutive nights a resident trainee can be on "night float," from six to seven nights. To our knowledge, although investigators have studied overall discrepancy rates and discrepancy rates as a function of shift length or perceived workload of a particular shift, no study has been performed to evaluate resident-faculty discrepancy rates as a quality/performance proxy, to see whether resident performance declines as a function of the number of consecutive nights. Our hypothesis is that we would observe a progressive increase in significant overnight resident- attending discrepancies over the 7days' time.

A total of 8,488 reports were extracted between 4/26/2019 to 8/22/2019 retrospectively. Data was obtained from the voice dictation system report server. selleck compound Exported query was saved as a .csv file format and analyzed using Python packages. A "discrepancy checker" was created to search he course of the week.

Our results reveal no convincing trend in terms of overnight report discrepancies between the preliminary report generated by the night float resident and the final report issued by a faculty the following morning. These results are in support of the ACGME's recent change in the permissible number of consecutive nights on night float. We did not prove our hypothesis that resident performance on-call in the domain of report accuracy would diminish over seven consecutive nights while on the night float rotation. Our results found that performance remained fairly uniform over the course of the week.

Few studies describe the impact of antimicrobial stewardship programs (ASPs) on recognizing and preventing diagnostic errors. Handshake stewardship (HS-ASP) is a novel ASP model that prospectively reviews hospital-wide antimicrobial usage with recommendations made in person to treatment teams. The purpose of this study was to determine if HS-ASP could identify and intervene on potential diagnostic errors for children hospitalized at a quaternary care children's hospital.

Previously self-identified "Great Catch" (GC) interventions by the Children's Hospital Colorado HS-ASP team from 10/2014 through 5/2018 were retrospectively reviewed. Each GC was categorized based on the types of recommendations from HS-ASP, including if any diagnostic recommendations were made to the treatment team. Each GC was independently scored using the "Safer Dx Instrument" to determine presence of diagnostic error based on a previously determined cut-off score of≤1.50. Interrater reliability for the instrument was measured using a randomized subset of one third of GCs.

During the study period, there were 162GC interventions. Of these, 65 (40%) included diagnostic recommendations by HS-ASP and 19 (12%) had a Safer Dx Score of≤1.50, (Κ=0.44; moderate agreement). Of those GCs associated with diagnostic errors, the HS-ASP team made a diagnostic recommendation to the primary treatment team 95% of the time.

Handshake stewardship has the potential to identify and intervene on diagnostic errors for hospitalized children.

Currently, NICE recommends the use of faecal immunochemical test (FIT) at faecal haemoglobin concentrations (f-Hb) of 10μg Hb/g faeces to stratify for colorectal cancer (CRC) risk in symptomatic populations. This f-Hb cut-off is advised across all analysers, despite the fact that a direct comparison of analyser performance, in a clinical setting, has not been performed.

Two specimen collection devices (OC-Sensor, OC-S; HM-JACKarc, HM-J) were sent to 914 consecutive individuals referred for follow up due to their increased risk of CRC. Agreement of f-Hb around cut-offs of 4, 10 and 150µg Hb/g faeces and CRC detection rates were assessed. Two OC-S devices were sent to a further 114 individuals, for within test comparisons.

A total of 732 (80.1%) individuals correctly completed and returned two different FIT devices, with 38 (5.2%) CRCs detected. Median f-Hb for individuals diagnosed with and without CRC were 258.5 and 1.8µg Hb/g faeces for OC-S and 318.1 and 1.0µg Hb/g faeces for HM-J respectively. Correlation of f-Hb results between OC-S/HM-J over the full range was rho=0.74, p<0.001. Using a f-Hb of 4µg Hb/g faeces for both tests found an agreement of 88.1%, at 10µg Hb/g faeces 91.7% and at 150µg Hb/g faeces 96.3%. A total of 114 individuals completed and returned two OC-S devices; correlation across the full range was rho=0.98, p<0.001.

We found large variations in f-Hb when different FIT devices were used, but a smaller variation when the same FIT device was used. Our data suggest that analyser-specific f-Hb cut-offs are applied with regard to clinical decision making, especially at lower f-Hb.

Biotin >20ng/mL may interfere with the Elecsys

Troponin T-high sensitive assay (cTnT-hs; Roche Diagnostics International Ltd). We evaluated the performance of an updated assay, cTnT-hs*, which was designed to reduce biotin interference.

cTnT-hs* assay performance was assessed using up to two applications (18min/9min) on three analyzers (cobas e 411/cobas e 601/cobas e 801). Biotin interference was determined by measuring recovery in an 11-sample series dilution with biotin ranging from 0-3600ng/mL. Repeatability/reproducibility were evaluated in five serum sample pools (n=75 each). Method comparisons tested cTnT-hs* vs. cTnT-hs (18min/cobas e 601); cTnT-hs* assay 18 vs. 9min (cobas e 601); cTnT-hs* (18min) on cobas e 601 vs. cobas e 411 and cobas e 601 vs. cobas e 801. Concordance at the 99th percentile decision limit between cTnT-hs* and cTnT-hs (9min/cobas e 601) was calculated using 300 lithium-heparin plasma samples and a 14ng/L assay cutoff.

cTnT-hs* assay (18min/cobas e 601) recovery was≥96% for biotin≤1250ng/mL.
