Sub-optimal routine HIV testing rates in an urban HIV and infectious disease clinic.

Background: Routine opt-out HIV testing is central to ending the HIV epidemic, as early case finding improves outcomes and reduces transmission. Despite strong evidence-based guideline recommendations, adoption of routine opt-out testing has been sub-optimal. Methods: A survey of providers and staff at an urban HIV and infectious disease clinic assessed awareness and knowledge of guidelines, screening practices, testing barriers, and possible interventions to improve testing. Responses were compared against actual testing data. Results: 86% of survey responders reported familiarity with guideline recommendations, and 37% reported routinely offering opt-out testing to all patients. A review of presumed HIV-negative patients over a two-year period showed that 7% of eligible patients had HIV screening ordered. Despite reported awareness of recommended routine HIV testing, testing was associated with perceived risk rather than offered uniformly, and potentially hampered by the COVID-19 pandemic and utilization of telemedicine visits. Provider education and electronic reminders, patient education, and rapid HIV test availability were proposed interventions to improve screening rates. Conclusions: Routine HIV testing was underutilized, with tests ordered based on perceived acquisition risk rather than offered uniformly.

Documentation quality of patient-directed discharge and early warning interactions in an adult inpatient service.

Documentation quality of patient-physician discussion, assessment, and intervention at the time of patient-directed discharges (elopement and 'against medical advice' discharges) is found to be poor in available studies and, importantly, may be a proxy for quality of care delivered. Less is known about the patient-physician interactions and documentation at the time a patient vocalizes the desire to leave early ('early warning interaction') prior to a patient-directed discharge. This was a cohort study comprising a retrospective chart review of patients leaving 'against medical advice' from an inpatient internal medicine-infectious disease service at a tertiary medical center from 01 July 2020 to 24 September 2021. Documentation quality was assessed using 11 extractable factors detailing patient-physician conversation elements from the assess, investigate, mitigate, explain, and document framework, plus related interventions pertinent to patient safety and care optimization. Descriptive statistics were mainly utilized with inferential statistics and regression models as appropriate. Fifty-two patients left against medical advice and 49 eloped; 11% had an early warning interaction. Aggregate documentation quality scores at early warning interaction (13%), 'against medical advice' discharge (42%), and at elopement (31%) were low. Half of the suggested documentation elements were recorded in no patients. The overall documentation quality was poor, suggesting the need for further training and interventions to facilitate more thorough documentation.

Factors Leading to Successful Performance on U.S. National Licensure Exams for Medical Students: A Scoping Review.

PURPOSE: To synthesize the evidence of the factors leading to successful performance on knowledge-based national licensure exams (NLEs) for medical students. METHOD: The authors conducted a scoping review to summarize the peer-reviewed empiric literature that used United States Medical Licensing Examination (USMLE) Step 1 or Step 2 Clinical Knowledge or Comprehensive Osteopathic Medical Licensing Examination (COMLEX) Level 1 or Level 2 Cognitive Evaluation scores as outcomes. The authors searched PubMed and Scopus without date restrictions through April 30, 2021. Two reviewers independently screened and selected studies for inclusion. Data were summarized narratively and with descriptive statistics. RESULTS: The authors screened 1,185 unique citations and included 233 full-text studies in their review. Of these, 201 (86%) were studies of USMLE exams, 31 (13%) were studies of COMLEX exams, and 1 (0.4%) reported on both. The authors classified 29 studies (12%) as informing NLE preparation, 163 (70%) as attempting to identify predictive variables, and 76 (33%) as using NLE scores for program evaluation. Preparation studies found that the number of practice test items, practice exam scores, and less time in dedicated preparation correlated with higher NLE scores. Use of other commercial resources or study strategies was not consistently associated with higher scores. Predictive studies found the strongest relationships between individuals' performance on past assessments and their NLE scores. CONCLUSIONS: The factors leading to successful performance on knowledge-based NLEs align with well-known principles from the cognitive sciences. Learners build on existing foundations of knowledge (reflected in their prior academic performance) and are likely to learn more efficiently with testing and spaced learning over time. While commercial test preparation resources are ubiquitous, there is no evidence that a single resource gives students a competitive advantage on NLEs. Developing habits of regular and continuous learning is necessary for clinical practice and successful NLE performance.

Feasibility of Tele-Training to Acquire Sublingual Microcirculatory Images.

Background: Recent advances in device technology and image analysis software used to assess the sublingual microcirculation have expanded clinicians' understanding of hemodynamics beyond assessments of blood pressure and end-organ function to provide unique insight into blood flow at the tissue level. Similarly, significant advances in virtual education and telemedicine have transpired recently, especially during the coronavirus disease (COVID-19) pandemic. However, the training of clinicians to acquire microcirculation images continues to rely on in-person instruction, which can be limited by available local expertise and resources, as well as geographic access to instructors. Objective: Our project aimed to test the feasibility of deploying an online curriculum in combination with tele-guidance versus an in-person guided approach to instruct novices to understand basic principle of microcirculatory function and to acquire sublingual microcirculatory images. Methods: After participating in brief didactics, 14 participants were divided into two groups to acquire microcirculatory images on a healthy volunteer. Each participant either 1) obtained images after an in-person demonstration or 2) obtained images with tele-guidance by using FaceTime technology. We recorded individual microcirculation quality scores, necessary time to acquire each image, percentage of correct theoretical questions on assessments, participant satisfaction with the curriculum, and participants' degree of confidence with image acquisition. Results: Participants' image quality scores (14.7 vs. 23.6, P = 0.3) and time to acquire images (191.2 vs. 199.4 s) did not significantly differ. In addition, participants' scores on theoretical knowledge assessments improved over the course of training (19.0% vs. 54.8%, P < 0.05). Conclusion: This feasibility study provides a novel framework for how to successfully deploy asynchronous education and telemedicine to direct novices to acquire sublingual microcirculatory images. Using technological advances to teach microcirculation may enhance wide-scale adoption of a promising clinical monitoring tool for critically ill patients.

Student well-being during dedicated preparation for USMLE Step 1 and COMLEX Level 1 exams.

BACKGROUND: Nearly all U.S. medical students engage in a 4-8 week period of intense preparation for their first-level licensure exams, termed a "dedicated preparation period" (DPP). It is widely assumed that student well-being is harmed during DPPs, but evidence is limited. This study characterized students' physical, intellectual, emotional, and social well-being during DPPs. METHODS: This was a cross-sectional survey sent electronically to all second-year students at four U.S. medical schools after each school's respective DPP for USMLE Step 1 or COMLEX Level 1 in 2019. Survey items assessed DPP characteristics, cost of resources, and perceived financial strain as predictors for 18 outcomes measured by items with Likert-type response options. Open-ended responses on DPPs' influence underwent thematic analysis. RESULTS: A total of 314/750 (42%) students completed surveys. DPPs lasted a median of 7 weeks (IQR 6-8 weeks), and students spent 70 h/week (IQR 56-80 h/week) studying. A total of 62 (20%) reported experiencing a significant life event that impacted their ability to study during their DPPs. Most reported 2 outcomes improved: medical knowledge base (95%) and confidence in ability to care for patients (56%). Most reported 9 outcomes worsened, including overall quality of life (72%), feeling burned out (77%), and personal anxiety (81%). A total of 25% reported paying for preparation materials strained their finances. Greater perceived financial strain was associated with worsening 11 outcomes, with reported amount spent associated with worsening 2 outcomes. Themes from student descriptions of how DPPs for first-level exams influenced them included (1) opportunity for synthesis of medical knowledge, (2) exercise of endurance and self-discipline required for professional practice, (3) dissonance among exam preparation resource content, formal curriculum, and professional values, (4) isolation, deprivation, and anguish from competing for the highest possible score, and (5) effects on well-being after DPPs. CONCLUSIONS: DPPs are currently experienced by many students as a period of personal and social deprivation, which may be worsened by perceived financial stress more than the amount of money they spend on preparation materials. DPPs should be considered as a target for reform as medical educators attempt to prevent student suffering and enhance their well-being.

Renin Kinetics Are Superior to Lactate Kinetics for Predicting In-Hospital Mortality in Hypotensive Critically Ill Patients.

OBJECTIVES: Whole blood lactate concentration is widely used in shock states to assess perfusion. We aimed to determine if the change in plasma renin concentration over time would be superior to the change in lactate concentration for predicting in-hospital mortality in hypotensive patients on vasopressors. DESIGN: Prospective, observational cohort study. SETTING: Tertiary academic ICU. PATIENTS: Adult patients on vasopressors for greater than 6 hours to maintain a mean arterial pressure greater than or equal to 65 mm Hg during January 2020. INTERVENTIONS: Plasma renin concentrations were measured at enrollment and at 24, 48, and 72 hours. Whole blood lactate measurements were performed according to normal standard of care. Logistic regression was performed to evaluate whether the change in renin or lactate concentration could predict in-hospital mortality. Generalized estimating equations were used to analyze the association between renin and lactate concentration and in-hospital mortality. The area under the receiver operating characteristics curve was performed to measure the discriminative ability of initial and peak renin and lactate concentration to predict mortality. The association between renin and lactate concentration above the upper limit of normal at each timepoint with in-hospital mortality was also examined. MEASUREMENTS AND MAIN RESULTS: The study included 197 renin and 148 lactate samples obtained from 53 patients. The slope of the natural log (ln) of renin concentration was independently associated with mortality (adjusted odds ratio, 10.35; 95% CI, 1.40-76.34; p = 0.022), but the slope of ln-lactate concentration was not (adjusted odds ratio, 4.78; 95% CI, 0.03-772.64; p = 0.55). The generalized estimating equation models found that both ln-renin (adjusted odds ratio, 1.18; 95% CI, 1.02-1.37; p = 0.025) and ln-lactate (adjusted odds ratio, 2.38; 95% CI, 1.05-5.37; p = 0.037) were associated with mortality. Area under the receiver operating characteristics curve analysis demonstrated that initial renin could predict in-hospital mortality with fair discrimination (area under the receiver operating characteristics curve, 0.682; 95% CI, 0.503-0.836; p = 0.05), but initial lactate could not (area under the receiver operating characteristics curve, 0.615; 95% CI, 0.413-0.803; p = 0.27). Peak renin (area under the receiver operating characteristics curve, 0.728; 95% CI, 0.547-0.888; p = 0.01) and peak lactate (area under the receiver operating characteristics curve, 0.746; 95% CI, 0.584-0.876; p = 0.01) demonstrated moderate discrimination. There was no significant difference in discriminative ability between initial or peak renin and lactate concentration. At each study time point, a higher proportion of renin values exceeded the threshold of normal (40 pg/mL) in nonsurvivors than in survivors, but this association was not significant for lactate. CONCLUSIONS: Although there was no significant difference in the performance of renin and lactate when examining the absolute values of each laboratory, a positive rate of change in renin concentration, but not lactate concentration, over 72 hours was associated with in-hospital mortality. For each one-unit increase in the slope of ln-renin, the odds of mortality increased 10-fold. Renin levels greater than 40 pg/mL, but not lactate levels greater than 2 mmol/L, were associated with in-hospital mortality. These findings suggest that plasma renin kinetics may be superior to lactate kinetics in predicting mortality of hypotensive, critically ill patients.

Embryonal Rhabdomyosarcoma with Posttherapy Cytodifferentiation and Aggressive Clinical Course.

Rhabdomyosarcoma is the most common soft tissue sarcoma in children and adolescents. Embryonal rhabdomyosarcoma (ERMS), its most common subtype, is a malignant soft tissue tumor with morphologic and immunophenotypic features of embryonic skeletal muscle. The histologic findings in ERMS typically include a range of differentiation in rhabdomyoblasts from primitive to terminally differentiated forms, and the latter become more prominent after chemotherapy-induced cytodifferentiation. Several reports have shown therapy-related cytodifferentiation to portend a good prognosis in ERMS. We discuss the case of a pediatric patient who presented with ERMS of the orbit. Although her tumor showed extensive posttreatment cytodifferentiation and several other good prognostic clinicopathologic factors, it pursued an aggressive course, resulting in early metastasis and death. This case represents an unusual course and may be instructive as to the clinicopathologic features impacting prognostication, and ultimately the biology, of this aggressive family of tumors.

Safety Matters: A Meta-analysis of Interhospital Transport Adverse Events in Critically Ill Patients.

OBJECTIVE: Interhospital transport (IHT) is common among critically ill patients. Our meta-analysis investigated the prevalence and possible factors associated with adverse events (AEs) during IHT. METHODS: Searching PubMed, Embase, and Scopus databases until February 12, 2021, we included studies that a priori defined AEs for adult medical patients. We excluded case reports, non-full-text, and non-English language studies. We performed a random effects meta-analysis and moderator analyses. RESULTS: We identified 554 studies and included 19 studies (14,969 patients) in our final analysis. The mean patients' (standard deviation) age was 60 (13.7). The pooled medical AEs for IHT was 1,059 (11%, 95% confidence interval, 7.5%-16%). The most common AE (n, %) was hypotension (424, 2.8%). Moderator analyses and meta-regressions suggested that conditions (P < .001) such as respiratory failure from coronavirus infection (88%), stroke (19%), and the need for extracorporeal membrane oxygenation (40%) were associated with higher AE prevalence. Transport by nurses (31%) and physicians (11%) was associated with a higher AE prevalence, whereas transport type did not influence AE prevalence. CONCLUSION: Our study suggests the prevalence of AEs of critically ill patients during IHT is low and likely due to patients' disease severity. Further studies should focus on interventions to mitigate AEs to improve patients' outcomes.

Prevalence of myocardial infarction among patients with chest pain and cocaine use: A systematic review and meta-analysis.

BACKGROUND: Cocaine abuse is a public health burden. Cocaine is known to cause vasospasm and acute myocardial infarction (AMI). The prevalence of AMI in patients presenting with chest pain and concurrent cocaine use (CPCC) varies among studies. We performed a systemic review and meta-analysis to assess the current literature for the prevalence of AMI in patients with CPCC. METHODS: We performed a literature search of PubMed, EMBASE, and Scopus from its beginning to May 18, 2020 and updated this search on February 18, 2021. Full-text studies that assessed the primary outcome (AMI) specifically among patients with CPCC who presented to the emergency department (ED) were included. We excluded studies that were not in English, did not take place in the ED, and case reports, which only reported positive cases and not incidence of AMI. Random effect meta-analysis was performed to assess the prevalence of primary outcome and to examine correlations between risk factors and AMI. Heterogeneity was assessed by I-square value. We also performed subgroup analysis to identify potential sources of heterogeneity. RESULTS: We identified 2178 studies and screened 102 full-text studies to include 16 studies (3269 patients) in our final analysis. The pooled prevalence of AMI was 4.7% (95% CI 0.8-23), I-square of 84%. However, rates among studies of low risk patients were lower (1.1% 95% CI 0.2-5) compared to studies of mixed risk patients (7.7%, 95% 5-11). A meta-regression was used to look at correlation between risk factors and AMI and found that AMI was positively correlated in patients with a history of CAD (correlation coefficient [Corr. Coeff.] 5.6, 96% CI 2.3-8.7), HTN (Corr. Coeff. 2.9, 95% CI 0.9-4.9), DM (Corr. Coeff. 8.0, 95% CI 2.4-14), HLD (Corr. Coeff. 5.9, 95% CI 2.4, 9). Sources of potential heterogeneity included patients' risk as defined by the authors, study designs, publication year, and study sample size. CONCLUSION: The overall prevalence of AMI and death among patients with cocaine-associated chest pain was relatively low, although high risk patients were still associated with high prevalence of AMI. Clinicians should consider risk-stratify these patients and treat them accordingly.

Sublingual Microcirculatory Characteristics of a Case of Profound Chemotherapy-Induced Anemia Treated With a Hemoglobin-Based Oxygen Carrier.

Handheld vital microscopy (HVM) can deepen our understanding of hematologic diseases and therapeutics. However, limited reports have assessed human microcirculation during profound anemia, and response to hemoglobin-based oxygen carriers (HBOCs). A 58-year-old woman presented with constitutional symptoms and was diagnosed with acute myeloblastic leukemia. Subsequently, the patient clinically decompensated and was found to have a hemoglobin of 1.9 g/dL. Human blood product administration was not consistent with her beliefs, and she received supportive care with HBOC-201. Concomitantly, her sublingual microcirculation revealed a markedly low microvascular flow index (2.59±0.26), proportion perfused vessels (66.8±18.8%), perfused vessel density (4.41±0.56 mm/mm2), and total vessel density (6.93±1.91 mm/mm2). HVM imaging is a promising point-of-care device for various hematologic conditions, with the potential to understand tissue-level perfusion in novel clinical scenarios, including profound anemia and HBOC administration, as illustrated in this case report.

Survey of the American Pediatric Surgical Association on cannulation practices in pediatric ECMO.

AIMS: Extracorporeal membrane oxygenation (ECMO) is a commonly used modality of life support for children with cardiopulmonary failure. Consensus on pediatric cannulation strategies and management does not currently exist. The goal of this study was to investigate individual surgeon approaches towards ECMO cannulations in children. METHODS: A 21-question online survey was developed and disseminated to the American Pediatric Surgical Association (APSA) membership. Participant responses were summarized as counts and percentages. Effect of ECMO volume and surgeon experience on responses was assessed. RESULTS: There were 252 APSA members who participated in this study for a response rate of 21%, with 225 (89.3%) performing ECMO. Sixty respondents (28.3%) reported using neck vessels exclusively for cannulation regardless of age or weight of the patient. After neck decannulation, 13 (6.6%) repaired the carotid artery for all patients, and 21 (10.7%) repaired only for children older than 5years. Of those performing femoral cannulation, 56 (26.4%) would perform at 5years or older and 66 (31.1%) at 12years. The most common challenge for femoral cannulation was the need for distal perfusion (n=119; 59.8%). Assistance from vascular surgery was requested by 32 (16.4%) for distal perfusion catheter placement, and by 79 (40.5%) for decannulation. Regarding femoral cannulation, lack of training was more likely to be a challenge if performing <5 cannulations per year (25.2% vs 12.5%; p=0.03). Surgeons with <10years of experience were more likely to consult vascular surgery compared to those with >10years of experience (18.5% vs 8%; p=0.03). CONCLUSION: Considerable variation exists in individual surgeon cannulation practices in pediatric ECMO, in particular in the management of school age and adolescent VA ECMO. Mixed approaches across several ECMO management case study questions indicate that further work is needed to evaluate specific risks with cannulations in children. LEVEL OF EVIDENCE: IV.
