RESUMEN
Introduction: Asynchronous online message boards (OMBs) allow users to write questions or comments and share them with an online group. While the use of OMBs has been associated with positive outcomes in several educational settings, their use has not been studied in pre-clerkship undergraduate medical education (UME). Methods: This multiyear, observational, longitudinal study examined patterns of OMB use in pre-clerkship UME. Descriptive statistics were used to report the number of students and instructors who logged on and contributed, the number of posts, instructor answers, post views, and the average time to answer. Patterns of use by first- and second-year medical students as well as students undergoing remote versus in-person learning were compared using Wilcoxon signed-rank tests. Results: A total of 9870 posts were made to OMBs, initiated by 3869 student questions. There were 3078 total posts made by instructors and academic support staff and 1024 student answers to student questions. First-year medical students posted significantly more questions (149.83 vs. 83.7, p < 0.001), which resulted in significantly more instructor answers (125.0 vs. 59.1, p < 0.001). Modules during the remote learning period received more student questions (152.0 vs. 96.7, p < 0.001) and produced more instructor answers (123.8 vs. 74.7, p < 0.001) as compared to modules that took place during in-person learning. Discussion: Online message boards represent a readily available tool to stimulate asynchronous discussion in pre-clerkship UME. First-year medical students and students during remote learning were more active on OMBs.
RESUMEN
INTRODUCTION: Fellows in critical care medicine (CCM) routinely help patients and families navigate complex decisions near the end of life. These "late goals of care" (LGOC) discussions require rigorous skills training and impact patient care. Innovation is needed to ensure that fellow training in leading these discussions is centered on reproducible competency-based standards. The aims of this study were to (1) describe the development of a simulation-based mastery learning (SBML) curriculum for LGOC discussions and (2) set a defensible minimum passing standard (MPS) to ensure uniform skill acquisition among learners. INNOVATION: We developed an SBML curriculum for CCM fellows structured around REMAP, a mnemonic outlining foundational components of effective communication around serious illness. A multidisciplinary expert panel iteratively created an LGOC discussion assessment tool. Pilot testing was completed to refine the checklist, set the MPS, and assess skill acquisition. OUTCOMES: The LGOC discussion assessment tool included an 18-item checklist and 6 scaled items. The tool produced reliable data (k ≥ 0.7 and ICC of ≥ 0.7). Using the Mastery Angoff method, the panel set the MPS at 87%. Ten CCM fellows participated in the pilot study. Performance on the checklist significantly improved from a median score of 52% (IQR 44%-72%) at pretest to 96% (IQR 82%-97%) at post-test (P = 0.005). The number of learners who met the MPS similarly improved from 10% during pre-testing to 70% during post-testing (P = 0.02). COMMENT: We describe the development of a LGOC SBML curriculum for CCM fellows which includes a robust communication skills assessment and the delineation of a defensible MPS.

Rationale: Critically ill patients who develop invasive pulmonary aspergillosis (IPA) have high mortality rates despite antifungal therapy. Diagnosis is difficult in these patients. Bronchoalveolar lavage (BAL) fluid galactomannan (GM) is a helpful marker of infection, although the optimal cutoff for IPA is unclear. We aimed to evaluate the BAL fluid GM and fungal culture results, demographics, and outcomes among a large cohort of mechanically ventilated patients with suspected pneumonia. Methods: A single-center cohort study of patients enrolled in the Successful Clinical Response in Pneumonia Therapy (SCRIPT) study from June 2018 to March 2023. Demographics, BAL results, and outcomes data were extracted from the electronic health record and compared between groups of patients who grew Aspergillus on a BAL fluid culture, those who had elevated BAL fluid GM levels (defined as >0.5 or >0.8) but did not grow Aspergillus on BAL fluid culture, and those with neither. Results: Of over 1700 BAL samples from 688 patients, only 18 BAL samples grew Aspergillus. Patients who had a BAL sample grow Aspergillus (n=15) were older (median 71 vs 62 years, p=0.023), had more days intubated (29 vs 11, p=0.002), and more ICU days (34 vs 15, p=0.002) than patients whose BAL fluid culture was negative for Aspergillus (n=672). The BAL fluid galactomannan level was higher from samples that grew Aspergillus on culture than those that did not (median ODI 7.08 vs 0.11, p<0.001), though the elevation of BAL fluid GM varied across BAL samples for patients who had serial sampling. Patients who grew Aspergillus had a similar proportion of underlying immunocompromise compared with the patients who did not, and while no statistically significant difference in overall unfavorable outcome, had longer duration of ventilation and longer ICU stays. Conclusions: In this large cohort of critically ill patients with a high number of BAL samples with GM levels, we found a relatively low rate of Aspergillus growth. Patients who eventually grew Aspergillus had inconsistently elevated BAL fluid GM, and many patients with elevated BAL fluid GM did not grow Aspergillus. These data suggest that the pre-test probability of invasive pulmonary aspergillosis should be considered low in a general ICU population undergoing BAL evaluation to define the etiology of pneumonia. Improved scoring systems are needed to enhance pre-test probability for diagnostic test stewardship purposes.
