RESUMO
BACKGROUND/OBJECTIVES: To develop and evaluate a post-acute care simulation-based mastery learning (SBML) continuing medical education (CME)/maintenance of certification (MOC) procedure course. DESIGN: Pretest-posttest study of the SBML intervention. SETTING: A 2-day post-acute care procedures course. PARTICIPANTS: Sixteen practicing clinicians (5 physicians,11 advanced practice providers). Participants engaged in a skills pretest on knee aspiration/injection, gastrostomy tube removal/replacement, tracheostomy tube exchange, and basic suturing using a checklist created for each procedure. Participants received a didactic on each procedure followed by deliberate practice with feedback. Using the same checklists, participants completed a skills posttest and were required to meet a minimum passing standard (MPS) to obtain CME/MOC credit. MEASUREMENTS: The MPS for each skills checklist was determined by a multidisciplinary panel of 11 experts. Participants completed surveys on procedure self-confidence and a course evaluation. RESULTS: There was statistically significant improvement between pre- and posttests for all four procedures (p < .001). All participants were able to meet or exceed the MPS for each skill during the 2-day course. Participants' self-confidence regarding each procedure improved significantly (p < .001). CONCLUSION: An SBML training course granting CME/MOC credit for post-acute care providers significantly improves performance of knee aspiration/injection, gastrostomy tube removal/replacement, tracheostomy tube exchange, and basic suturing.

OBJECTIVES: Central venous catheter insertions may lead to preventable adverse events. Attending physicians' central venous catheter insertion skills are not assessed routinely. We aimed to compare attending physicians' simulated central venous catheterinsertion performance to published competency standards. DESIGN: Prospective cohort study of attending physicians' simulated internal jugular and subclavian central venous catheter insertion skills versus a historical comparison group of residents who participated in simulation training. SETTING: Fifty-eight Veterans Affairs Medical Centers from February 2014 to December 2014 during a 2-day simulation-based education curriculum and two academic medical centers in Chicago. SUBJECTS: A total of 108 experienced attending physicians and 143 internal medicine and emergency medicine residents. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: Using a previously published central venous catheter insertion skills checklist, we compared Veterans Affairs Medical Centers attending physicians' simulated central venous catheter insertion performance to the same simulated performance by internal medicine and emergency medicine residents from two academic centers. Attending physician performance was compared to residents' baseline and posttest (after simulation training) performance. Minimum passing scores were set previously by an expert panel. Attending physicians performed higher on the internal jugular (median, 75.86% items correct; interquartile range, 68.97-86.21) and subclavian (median, 83.00%; interquartile range, 59.00-86.21) assessments compared to residents' internal jugular (median, 37.04% items correct; interquartile range, 22.22-68.97) and subclavian (median, 33.33%; interquartile range, 0.00-70.37; both p < 0.001) baseline assessments. Overall simulated performance was poor because only 12 of 67 attending physicians (17.9%) met or exceeded the minimum passing score for internal jugular central venous catheter insertion and only 11 of 47 (23.4%) met or exceeded the minimum passing score for subclavian central venous catheter insertion. Resident posttest performance after simulation training was significantly higher than attending physician performance (internal jugular: median, 96%; interquartile range, 93.10-100.00; subclavian: median, 100%; interquartile range, 96.00-100.00; both p < 0.001). CONCLUSIONS: This study demonstrates highly variable simulated central venous catheter insertion performance among a national cohort of experienced attending physicians. Hospitals, healthcare systems, and governing bodies should recognize that even experienced physicians require periodic clinical skill assessment and retraining.

PURPOSE: Simulation-based mastery learning (SBML) is a rigorous form of competency-based learning. Components of SBML include a pretest, deliberate practice, and a posttest; all learners must meet or exceed a minimum passing standard (MPS) on the posttest before completing training. The authors aimed to explore whether a modified SBML curriculum (without a pretest assessment) was as effective as the standard SBML curriculum (with a pretest assessment). METHOD: The authors performed a randomized controlled trial of internal medicine residents who participated in an internal jugular central venous catheter insertion SBML curriculum at a tertiary care academic medical center in Chicago, Illinois, from December 2018 through December 2021. Residents were randomly assigned to complete the usual SBML intervention (pretest group) or to complete a modified SBML intervention without a pretest (no pretest group). The authors compared initial posttest performance and training time between groups. RESULTS: Eighty-nine of 120 eligible residents (74.1%) completed the study: 43 in the pretest group and 46 in the no pretest group. Median (IQR) initial posttest scores were not statistically different between the pretest group (96.6 [93.1-100]) and the no pretest group (96.6 [92.4-100]). However, all 43 residents (100%) in the pretest group reached the MPS at the initial posttest compared with 41 of the 46 (89%) in the no pretest group ( P = .06). Residents in the pretest group required 16.5 hours more faculty and learning time than the no pretest group. CONCLUSIONS: More residents who completed a pretest reached the MPS at initial posttest. However, incorporating a pretest during the internal jugular central venous catheter SBML curriculum required substantially more learner and faculty time without clear performance benefits.

OBJECTIVES: The aims of the study were to identify perceived barriers and facilitators to central venous catheter (CVC) insertion among healthcare providers and to understand the extent to which an existing Simulation-Based Mastery Learning (SBML) program may address barriers and leverage facilitators. METHODS: Providers participating in a CVC insertion SBML train-the-trainer program, in addition to intensive care unit nurse managers, were purposively sampled from Veterans Administration Medical Centers located in geographically diverse areas. We conducted semistructured interviews to assess perceptions of barriers and facilitators to CVC insertion. Deidentified transcripts were analyzed using a grounded theory approach and the constant comparative method. We subsequently mapped identified barriers and facilitators to our SBML curriculum to determine whether or not the curriculum addresses these factors. RESULTS: We interviewed 28 providers at six Veterans Administration Medical Centers, identifying the following five overarching factors of perceived barriers to CVC insertion: (1) equipment, (2) personnel/staff, (3) setting or organizational context, (4) patient or provider, and (5) time-related barriers. Three overarching factors of facilitators emerged: (1) equipment, (2) personnel, and (3) setting or organizational context facilitators. The SBML curriculum seems to address most identified barriers, while leveraging many facilitators; building on the commonly identified facilitator of nursing staff contribution by expanding the curriculum to explicitly include nurse involvement could improve team efficiency and organizational culture of safety. CONCLUSIONS: Many identified facilitators (e.g., ability to use ultrasound, personnel confidence/competence) were also identified as barriers. Evidence-based SBML programs have the potential to amplify these facilitators while addressing the barriers by providing an opportunity to practice and master CVC insertion skills.

Objectives: Simulation-based mastery learning (SBML) programs have been shown to be beneficial to improve procedural skill acquisition. However, simulated procedure performance can be affected by a host of factors, including stress. This investigation examined the preliminary efficacy of bolstering an established SBML program for medical residents with a brief mindfulness intervention (called a PITSTOP) to reduce procedural stress and improve simulator performance. Design: The study employed a partially blinded, parallel-group, randomized, repeated-measures intention-to-treat design. Participants were blinded to the primary outcome (simulator performance) and instead were informed of the study's secondary outcome (stress prevention). The SBML faculty instructors and study investigators were blinded to participants' group assignment. Settings/location: Northwestern Memorial Hospitals of Chicago. Subjects: Twenty-six postgraduate year (PGY) 1 internal medicine residents enrolled in a required SBML central venous catheter (CVC) insertion training from June 2015 to January 2018 participated in the study. Interventions: SBML consists of a simulated skills pretest, deliberate practice, and a simulated skills post-test (within 1 week of pretest). PGY 1 participants were randomly assigned to the PITSTOP intervention (12-min PITSTOP mindfulness training video) or control group (12-min control video on ways to increase physical activity) before the SBML pretest. Outcome measures: The primary outcome was a comparison of each group's simulator performance during pre- and post-tests. Secondary outcomes were changes in groups' procedural stress during these tests (assessed using self-reported, instructor-rated, and physiologic indicators), and self-reported self-regulation outcomes. Results: Residents who watched the PITSTOP video before their SBML training made fewer procedural errors relative to controls during their pretest for intrajugular CVC insertion (p = 0.03). PITSTOP participants also had lower heart rate (p = 0.03) and less visible trembling (p = 0.003) relative to controls at the post-test. Conclusions: This study provides preliminary evidence that a brief, mindfulness intervention may reduce stress during SBML training.

This article was migrated. The article was marked as recommended. Background Studies show that medical residents do not feel comfortable and lack the skills and confidence to perform common bedside procedures. Regulatory bodies often require a set number of procedures to determine resident competence, yet medical providers' knowledge of competency guidelines are less well known. This study aimed to qualitatively assess existing practices relevant to documentation of competency in central venous catheter (CVC) insertion and explore healthcare providers' awareness and perceptions of those practices at their institutions. Methods The authors performed a qualitative study at Veterans Affairs Medical Centers (VAMCs) from February to December 2014 as part of a larger project related to the dissemination of a simulation-based CVC insertion curriculum. Two authors conducted interviews with hospital staff (including attending physicians, nurses, and residents) at selected VAMCs. Recordings of interviews were transcribed, coded, and analyzed using a grounded theory approach and constant comparative techniques. Results Twenty-six participants were interviewed at six VAMCs. Participants reported varying perspectives regarding their institutions' policies about CVC insertion. Four major themes emerged: (1) knowledge of institutional policy; (2) competency by numbers; (3) documentation of competency; and (4) perceptions of competency measures. Participants reported concern about the reliability of these policies and measures of competence. Conclusions This study demonstrates that healthcare providers' knowledge and perceptions about institutional requirements for procedural competency vary widely. Our findings suggest the need for establishment of consistent competency policies based on evidence-based practices, and highlight the need for increased communication regarding individual institutional policies. Integration of rigorous simulation-based education, implemented consistently across institutions, can provide a reliable mechanism to train and assess procedural competence and ensure patient safety.
RESUMO
Measurement of the increase in digital pulse volume amplitude (PVA) during reactive hyperemia relative to baseline (PVA-RH) is being applied widely as a convenient test of nitric oxide bioavailability. However, evidence linking digital PVA-RH to nitric oxide is currently lacking. Accordingly, we investigated whether nitric oxide is responsible for the increase in digital PVA. During reactive hyperemia, we used a peripheral arterial tonometer to record digital PVA at baseline and during reactive hyperemia. The role of nitric oxide in these responses was investigated in 19 healthy subjects by inhibiting nitric oxide synthesis with N(G)-nitro-L-arginine methyl ester (L-NAME). Ten subjects underwent the identical protocol with saline and five with phenylephrine, a nonspecific vasoconstrictor, instead of L-NAME. The change in digital PVA after drug administration was compared between the three groups. Relative to the response with saline (-5 +/- 2%), baseline PVA was unchanged by L-NAME infusion (-10 +/- 2%), but it decreased significantly with phenylephrine (-50 +/- 12%; P = 0.003). PVA-RH increased slightly with saline infusion (9 +/- 4%). In comparison, PVA-RH was significantly blunted by L-NAME administration (-46 +/- 21%; P = 0.002) and was relatively unchanged by phenylephrine (20 +/- 9%). The present study establishes a central role for nitric oxide in the augmentation of PVA during reactive hyperemia. The measurement of digital PVA-RH may indeed provide a simple means of assessing endothelial function in humans.

Cigarette smoking impairs endothelial function. Hydroxymethylglutaryl (HMG) CoA reductase inhibitors (statins) may favorably affect endothelial function via nonlipid mechanisms. We tested the hypothesis that statins would improve endothelial function independent of changes in lipids in cigarette smokers. Twenty normocholesterolemic cigarette smokers and 20 matched healthy control subjects were randomized to atorvastatin 40 mg daily or placebo for 4 weeks, washed out for 4 weeks, and then crossed-over to the other treatment. Baseline low-density lipoprotein (LDL) levels were similar in smokers and healthy subjects, 103+/-22 versus 95+/-27 mg/dL, respectively (P=NS) and were reduced similarly in smokers and control subjects by atorvastatin, to 55+/-30 and 58+/-20 mg/dL, respectively (P=NS). Vascular ultrasonography was used to determine brachial artery, flow-mediated, endothelium-dependent, and nitroglycerin-mediated, endothelium-independent vasodilation. To elucidate potential molecular mechanisms that may account for changes in endothelial function, skin biopsy specimens were assayed for eNOS mRNA, eNOS activity, and nitrotyrosine. Endothelium-dependent vasodilation was less in smokers than nonsmoking control subjects during placebo treatment, 8.0+/-0.6% versus 12.1+/-1.1%, (P=0.003). Atorvastatin increased endothelium-dependent vasodilation in smokers to 10.5+/-1.3% (P=0.017 versus placebo) but did not change endothelium-dependent vasodilation in control subjects (to 11.0+/-0.8%, P=NS). Endothelium-independent vasodilation did not differ between groups during placebo treatment and was not significantly affected by atorvastatin. Multivariate analysis did not demonstrate any association between baseline lipid levels or the change in lipid levels and endothelium-dependent vasodilation. Cutaneous nitrotyrosine levels and skin microvessel eNOS mRNA, but not ENOS activity, were increased in smokers compared with controls but unaffected by atorvastatin treatment. Atorvastatin restores endothelium-dependent vasodilation in normocholesterolemic cigarette smokers independent of changes in lipids. These results are consistent with a lipid-independent vascular benefit of statins but could not be explained by changes in eNOS message and tissue oxidative stress. These findings implicate a potential role for statin therapy to restore endothelial function and thereby investigate vascular disease in cigarette smokers.
