Use of an Asynchronous Discussion Platform During the Pre-clerkship Curriculum: A Multiyear Retrospective Study.

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.

Description of the Novel Networking, Open Discussion, Engagement, and Self-Promotion (NODES) Framework for the Advancement of Women Physicians on Social Media.

The Networking, Open Discussion, Engagement, and Self-Promotion (NODES) framework is a strategy that women in medicine can deploy at conferences to broaden their professional networks and engage with colleagues. The NODES framework was designed and implemented for use at the Women in Medicine Summit, an annual conference that unites women to combat gender inequality in medicine. Intentional use of social media at conferences using the NODES framework by women in medicine can increase the visibility of research projects and may lead to speaking engagements and awards.

Physician and Biomedical Scientist Harassment on Social Media During the COVID-19 Pandemic.

This survey study assesses the frequency and nature of harassment on social media experienced by physicians, biomedical scientists, and trainees during the COVID-19 pandemic.

Barriers to enrollment in a pediatric critical care biorepository.

BACKGROUND: Individuals of minority race/ethnicity have lower rates of participation in genomic research. This study evaluated sociodemographic characteristics associated with decisions to enroll in a pediatric critical care biorepository. METHODS: Parents of children admitted to the PICU between November 2014 and May 2017 were offered to enroll their child in a biorepository using a single-page opt-in consent. Missed enrollment was assessed by failure to complete the form or declining consent on the form. We conducted a retrospective chart review for sociodemographic and clinical information. Bivariate and multivariable regression analyses were performed. RESULTS: In 4055 encounters, representing 2910 patients with complete data, 1480 (50%) completed the consent form and 1223 (83%) enrolled. We found higher odds of incomplete consent for non-English-speaking parents (OR = 2.1, p < 0.0001) and parents of children of all races except non-Hispanic white (OR = 1.27-1.99, p < 0.0001). We found higher odds of declined consent in patients with Medicaid (OR = 1.67, p = 0.003) and parents of children of all races except non-Hispanic white (OR = 1.32-2.9, p < 0.0001). CONCLUSION: Inability to enroll patients in a critical care biorepository may be associated with several sociodemographic factors at various points in recruitment/enrollment. IMPACT: Individuals of minority race/ethnicity are less likely to enroll in genomic research and in critical care research. This study evaluated sociodemographic characteristics associated with decisions to enroll a child in a pediatric critical care biorepository. Sociodemographic factors including race/ethnicity, primary language, and insurance status and patient clinical characteristics are associated with differential enrollment into a pediatric critical care biorepository. More research is needed to understand how study team-participant interactions may play a role in differential enrollment. Barriers to enrollment occur both at the time of approaching and consenting for enrollment.

Heart rate variability is associated with encephalopathy and outcomes in pediatric acute liver failure.

BACKGROUND: More than half of children with pediatric acute liver failure (PALF) experience hepatic encephalopathy (HE), which is related to poor outcomes; however, HE is difficult to diagnose in children. The objective of this study was to evaluate if heart rate variability (HRV), a continuous measure of autonomic nervous system function, was related to the presence and severity of HE as well as clinical outcomes in children with PALF. METHODS: We conducted a retrospective observational cohort study of 38 critically ill children with PALF to examine the association between HRV and HE severity and clinical outcome. HRV was estimated using the integer HRV (HRVi). Categorical variables were compared using the Fisher Exact test and continuous variables were compared using Kruskal-Wallis tests. Associations between grades of HE and minimum and median HRVi were evaluated with Pearson's correlation, with p values <0.05 considered significant. RESULTS: A more negative median and minimum HRVi, indicating poorer autonomic nervous system function, was significantly associated with abnormal EEG findings, presence of HE, and poor outcomes (death or listing for transplant). CONCLUSIONS: Heart rate variability may hold promise to predict outcomes in children with PALF, but these findings should be replicated in a larger sample. IMPACT: The findings of our study suggest that heart rate variability is associated with clinical outcomes in children with acute liver failure, a cohort for which prognostics are challenging, especially in young children and infants. Use of heart rate variability in the clinical setting may facilitate earlier detection of children with pediatric acute liver failure (PALF) at high risk for severe hepatic encephalopathy and poor outcomes. Identification of children with PALF at high risk of decompensation may assist clinicians in making decisions about liver transplantation, an important, but resource-limited, treatment of PALF.

Use of Twitter Amplifiers by Medical Professionals to Combat Misinformation During the COVID-19 Pandemic.

Social media is an important tool for disseminating accurate medical information and combating misinformation (ie, the spreading of false or inaccurate information) and disinformation (ie, spreading misinformation with the intent to deceive). The prolific rise of inaccurate information during a global pandemic is a pressing public health concern. In response to this phenomenon, health professional amplifiers such as IMPACT (Illinois Medical Professional Action Collaborative Team) have been created as a coordinated response to enhance public communication and advocacy around the COVID-19 pandemic.

Ethical Principles in Personal Protective Equipment Inventory Management Decisions and Partnerships Across State Lines During the COVID-19 Pandemic.

The COVID-19 pandemic created unprecedented strain on the personal protective equipment (PPE) supply chain. Given the dearth of PPE and consequences for transmission, GetMePPE Chicago (GMPC) developed a PPE allocation framework and system, distributing 886 900 units to 274 institutions from March 2020 to July 2021 to address PPE needs. As the pandemic evolved, GMPC made difficult decisions about (1) building reserve inventory (to balance present and future, potentially higher clinical acuity, needs), (2) donating to other states/out-of-state organizations, and (3) receiving donations from other states. In this case study, we detail both GMPC's experience in making these decisions and the ethical frameworks that guided these decisions. We also reflect on lessons learned and suggest which values may have been in conflict (eg, maximizing benefits vs duty to mission, defined in the context of PPE allocation) in each circumstance, which values were prioritized, and when that prioritization would change. Such guidance can promote a values-based approach to key issues concerning distribution of PPE and other scarce medical resources in response to the COVID-19 pandemic and related future pandemics.

Derivation and Validation of Novel Phenotypes of Multiple Organ Dysfunction Syndrome in Critically Ill Children.

Importance: Multiple organ dysfunction syndrome (MODS) is a dynamic and heterogeneous process associated with high morbidity and mortality in critically ill children. Objective: To determine whether data-driven phenotypes of MODS based on the trajectories of 6 organ dysfunctions have prognostic and therapeutic relevance in critically ill children. Design, Setting, and Participants: This cohort study included 20 827 pediatric intensive care encounters among 14 285 children admitted to 2 large academic pediatric intensive care units (PICUs) between January 2010 and August 2016. Patients were excluded if they were older than 21 years or had undergone cardiac surgery. The 6 subscores of the pediatric Sequential Organ Failure Assessment (pSOFA) score were calculated for the first 3 days, including the subscores for respiratory, cardiovascular, coagulation, hepatic, neurologic, and renal dysfunctions. MODS was defined as a pSOFA subscore of at least 2 in at least 2 organs. Encounters were split in a 80:20 ratio for derivation and validation, respectively. The trajectories of the 6 subscores were used to derive a set of data-driven phenotypes of MODS using subgraph-augmented nonnegative matrix factorization in the derivation set. Data analysis was conducted from March to October 2019. Exposures: The primary exposure was phenotype membership. In the subset of patients with vasoactive-dependent shock, the interaction between hydrocortisone and phenotype membership and its association with outcomes were examined in a matched cohort. Main Outcomes and Measures: The primary outcome was in-hospital mortality. Secondary outcomes included persistent MODS on day 7, and vasoactive-free, ventilator-free, and hospital-free days. Regression analysis was used to adjust for age, severity of illness, immunocompromised status, and study site. Results: There were 14 285 patients with 20 827 encounters (median [interquartile range] age 5.2 years [1.5-12.7] years; 11 409 [54.8%; 95% CI, 54.1%-55.5%] male patients). Of these, 5297 encounters (25.4%; 95% CI, 24.8%-26.0%) were with patients who had MODS, of which 5054 (95.4%) met the subgraph count threshold and were included in the analysis. Subgraph augmented nonnegative matrix factorization uncovered 4 data-driven phenotypes of MODS, characterized by a combination of neurologic, respiratory, coagulation, and cardiovascular dysfunction, as follows: phenotype 1, severe, persistent encephalopathy (1019 patients [19.2%]); phenotype 2, moderate, resolving hypoxemia (1828 patients [34.5%]); phenotype 3, severe, persistent hypoxemia and shock (1012 patients [19.1%]); and phenotype 4, moderate, persistent thrombocytopenia and shock (1195 patients [22.6%]). These phenotypes were reproducible in a validation set of encounters, had distinct clinical characteristics, and were independently associated with outcomes. For example, using phenotype 2 as reference, the adjusted hazard ratios (aHRs) for death by 28 days were as follows: phenotype 1, aHR of 3.0 (IQR, 2.1-4.3); phenotype 3, aHR of 2.8 (IQR, 2.0-4.1); and phenotype 4, aHR of 1.8 (IQR, 1.2-2.6). Interaction analysis in a matched cohort of patients with vasoactive-dependent shock revealed that hydrocortisone had differential treatment association with vasoactive-free days across phenotypes. For example, patients in phenotype 3 who received hydrocortisone had more vasoactive-free days than those who did not (23 days vs 18 days; P for interaction < .001), whereas patients in other phenotypes who received hydrocortisone either had no difference or had less vasoactive-free days. Conclusions and Relevance: In this study, data-driven phenotyping in critically ill children with MODS uncovered 4 distinct and reproducible phenotypes with prognostic relevance and possible therapeutic relevance. Further validation and characterization of these phenotypes is warranted.

Reducing Social Isolation of Seniors during COVID-19 through Medical Student Telephone Contact.

Social isolation has been associated with many adverse health outcomes in older adults. We describe a phone call outreach program in which health care professional student volunteers phoned older adults, living in long-term care facilities and the community, at risk of social isolation during the COVID-19 pandemic. Conversation topics were related to coping, including fears or insecurities, isolation, and sources of support; health; and personal topics such as family and friends, hobbies, and life experiences. Student volunteers felt the calls were impactful both for the students and for the seniors, and call recipients expressed appreciation for receiving the calls and for the physicians who referred them for a call. This phone outreach strategy is easily generalizable and can be adopted by medical schools to leverage students to connect to socially isolated seniors in numerous settings.

Surrogate Decision Making for Children: Who Should Decide?

OBJECTIVE: To identify caregivers' views on preferred surrogate decision makers for their children. STUDY DESIGN: A respondent-anonymous survey was distributed to a convenience sample of adults who accompanied a child to general and subspecialty pediatric care at 2 different institutions or were at the bedside of a child in the pediatric intensive care unit at a third institution in Chicago. RESULTS: We collected 462 valid surveys. The average age of the legal guardian and accompanying child was 36.8 years and 6.6 years, respectively. Most legal guardians designated "other parent with legal authority" as their first choice surrogate decision maker (70%). Respondent's sex, respondent's age, child's age, and child's ethnicity had no effect on first choice surrogate decision maker. "Other parent with legal authority" was less likely to be first choice surrogate if respondents had Medicaid insurance, less than a college degree, or lived in a non-nuclear household (P<.01 for all factors). The surrogacy ladder selected by 31% of legal guardians was "other parent with legal authority," "child's grandparent(s)," and "child's aunt(s) or uncle(s)." No other sequence received more than 10% designation. Study site had no effect on surrogate preference (P = .30). CONCLUSIONS: A surrogacy priority ladder for minors needs to include relatives who are often not included in state surrogacy statutes (eg, grandparents, aunts and uncles). The most popular surrogacy ladder will not be ideal for many families. Parents need to be informed and empowered to choose alternate surrogates, and documented preferences must be easily and widely accessible.

Validity of the WHIPLASHED as a tool to identify bipolar disorder in women.

BACKGROUND: The aim of this study was to investigate the validity of the WHIPLASHED clinician-administered interview, a mnemonic of questions on clinical factors and illness course used to screen for bipolar disorder, as a self-report questionnaire. METHODS: Participants (n = 82) were females recruited from an outpatient academic women's mental health clinic. Relevant symptom data were extracted from a self-report questionnaire designed to parallel the WHIPLASHED interview questions. A score of ≥5 on WHIPLASHED was defined as a positive screen for bipolar spectrum disorder by its developer. We examined the capacity of self-reported WHIPLASHED scores ≥5 to differentiate bipolar from unipolar depression in women. Diagnostic assessments were conducted with the Mini International Neuropsychiatric Interview. RESULTS: Women were diagnosed with unipolar (n = 54) and bipolar (n = 28) depression. The majority of subjects were white (67%), employed (68%) and married (57%) with a mean age of 36.8 years. The receiver operating characteristic curve demonstrated that WHIPLASHED had strong predictive ability (AUC = 0.877) in differentiating bipolar from unipolar depression. A cutoff score of ≥5 generated 96% sensitivity and 52% specificity, while raising the threshold to 6 generated 89% sensitivity and 76% specificity for a bipolar disorder diagnosis. LIMITATIONS: Our sample was small and composed of female patients at a single treatment center. CONCLUSIONS: In this sample, WHIPLASHED was a valid screening tool to differentiate bipolar from unipolar depression. While existing instruments focus on primary symptoms of bipolar disorder, the WHIPLASHED is useful in exploring subtypes of bipolar disorder in which depression dominates the clinical course.
