Discharge Clinical Characteristics and Post-Discharge Events in Patients with Severe COVID-19: A Descriptive Case Series.

BACKGROUND: As the SARS-CoV-2 pandemic continues, little guidance is available on clinical indicators for safely discharging patients with severe COVID-19. OBJECTIVE: To describe the clinical courses of adult patients admitted for COVID-19 and identify associations between inpatient clinical features and post-discharge need for acute care. DESIGN: Retrospective chart reviews were performed to record laboratory values, temperature, and oxygen requirements of 99 adult inpatients with COVID-19. Those variables were used to predict emergency department (ED) visit or readmission within 30 days post-discharge. PATIENTS (OR PARTICIPANTS): Age ≥ 18 years, first hospitalization for COVID-19, admitted between March 1 and May 2, 2020, at University of California, Los Angeles (UCLA) Medical Center, managed by an inpatient medicine service. MAIN MEASURES: Ferritin, C-reactive protein, lactate dehydrogenase, D-dimer, procalcitonin, white blood cell count, absolute lymphocyte count, temperature, and oxygen requirement were noted. KEY RESULTS: Of 99 patients, five required ED admission within 30 days, and another five required readmission. Fever within 24 h of discharge, oxygen requirement, and laboratory abnormalities were not associated with need for ED visit or readmission within 30 days of discharge after admission for COVID-19. CONCLUSION: Our data suggest that neither persistent fever, oxygen requirement, nor laboratory marker derangement was associated with need for acute care in the 30-day period after discharge for severe COVID-19. These findings suggest that physicians need not await the normalization of laboratory markers, resolution of fever, or discontinuation of oxygen prior to discharging a stable or improving patient with COVID-19.

To scan or not to scan? DXA in postmenopausal women.

Fracture is a major cause of morbidity and death in postmenopausal women. Dual-energy x-ray absorptiometry (DXA) measures bone mineral density, which helps in estimating fracture risk and in identifying those who may benefit from treatment. Although screening guidelines differ somewhat for postmenopausal women under age 65, in general, DXA is indicated if the patient has a high risk for fracture.

A machine learning algorithm to increase COVID-19 inpatient diagnostic capacity.

Worldwide, testing capacity for SARS-CoV-2 is limited and bottlenecks in the scale up of polymerase chain reaction (PCR-based testing exist. Our aim was to develop and evaluate a machine learning algorithm to diagnose COVID-19 in the inpatient setting. The algorithm was based on basic demographic and laboratory features to serve as a screening tool at hospitals where testing is scarce or unavailable. We used retrospectively collected data from the UCLA Health System in Los Angeles, California. We included all emergency room or inpatient cases receiving SARS-CoV-2 PCR testing who also had a set of ancillary laboratory features (n = 1,455) between 1 March 2020 and 24 May 2020. We tested seven machine learning models and used a combination of those models for the final diagnostic classification. In the test set (n = 392), our combined model had an area under the receiver operator curve of 0.91 (95% confidence interval 0.87-0.96). The model achieved a sensitivity of 0.93 (95% CI 0.85-0.98), specificity of 0.64 (95% CI 0.58-0.69). We found that our machine learning algorithm had excellent diagnostic metrics compared to SARS-CoV-2 PCR. This ensemble machine learning algorithm to diagnose COVID-19 has the potential to be used as a screening tool in hospital settings where PCR testing is scarce or unavailable.

Comparing the effectiveness of a hybrid simulation/lecture session versus simulation alone in teaching crew resource management (CRM) skills: a randomised controlled trial.

Introduction: Various methods have been used to teach crew resource management (CRM) skills, including high-fidelity patient simulation. It is unclear whether a didactic lecture added on to a simulation-based curriculum can augment a learner's education. Methods: Using an already existing simulation-based curriculum for interdisciplinary teams composed of both residents and nurses, teams were randomised to an intervention or control arm. The intervention arm had a 10 min didactic lecture after the first of three simulation scenarios, while the control arm did all three simulation scenarios without any didactic component. The CRM skills of teams were then scored, and improvement was compared between the two arms using general estimating equations. Results: The differences in mean teamwork scores between the intervention and control arms in scenarios 2 and 3 were not statistically significant. Mean scores in the intervention arm were lower than in the control arm (-0.57, p=0.78 for scenario 2; -3.12, p=0.13 for scenario 3), and the increase in scores from scenario 2 to 3 was lower in the intervention arm than in the control arm (difference in differences: -2.55, p=0.73). Conclusions: Adding a didactic lecture to a simulation-based curriculum geared at teaching CRM skills to interdisciplinary teams did not lead to significantly improved teamwork.

Cangrelor Bridging Within 6 Months of a Drug-Eluting Stent in a Patient for Emergency Cervical Spine Surgery: A Case Report.

The recommended duration of dual antiplatelet therapy after drug-eluting stent placement presents a dilemma for patients with recent stenting who require urgent or emergency noncardiac surgery. We present the case of a patient with recent drug-eluting stent placement (<6 months) on dual antiplatelet therapy who underwent successful emergency cervical spine surgery with antiplatelet therapy bridged using cangrelor, an intravenous P2Y12 inhibitor antiplatelet agent. Our experience illustrates the multidisciplinary approach to a patient with high thrombotic and bleeding risk who underwent neurosurgery off both aspirin and a P2Y12 inhibitor.

Competency-based Standard Setting for a High-stakes Objective Structured Clinical Examination (OSCE): Validity Evidence.

This article was migrated. The article was marked as recommended. Introduction Medical educators need to demonstrate that their trainees meet expected competency levels when progressing through medical education. This study aimed to develop competency-based pass/fail cut-scores for a graduation required Objective Structured Clinical Examination (OSCE), and examine validity evidence for new standards. Methods Six clinicians used the modified Angoff method to determine the cut-scores for an 8-station OSCE. The clinicians estimated the percentage of minimally competent students who would answer each checklist item correctly. Inter-rater reliability, differences in other academic achievements between pass/fail groups, educational impact, and response process were examined. Results One hundred seventy-four rising 4th-year medical students participated in the OSCE. The cut-scores determined for the OSCE resulted in a substantially lower failure rate (5% vs. 29% of the previous year). The inter-rater reliability across domains and cases was .98 (95% CI = .97 - .99). The pass/fail groups significantly differed in six of the eight measures of academic achievements included in the study. Discussion The impact of the standards setting was substantial as it significantly reduced the failure rate and burdens of remediation for both students and faculty. The very high inter-rater reliability indicates that the modified Angoff method produced reliable cut-scores. The significant differences between the pass/fail groups in other measures support external validity of the standards and ensure no false passes. The study also supports response process validity by including discussion among judges and check of previous student performances, as well as recruiting and training multiple clinician educators experienced in medical student teaching. Conclusion Findings of the study provide strong evidence supporting validity of the new cut-scores from a wide spectrum of validity metrics, including response process, internal structure, relations to other variables, and consequences. The study also added to the literature the value of the modified Angoff method in determining competency-based standards for OSCEs.

Mental health care for adults with suicide ideation.

OBJECTIVE: To estimate mental health and substance abuse services use for adults with and without suicide ideation. METHOD: 2000-2001 follow-up of respondents to a nationally representative survey. Measures include self-reports of suicide ideation, specialty and primary care mental health services use, past year counseling, psychotropic medications and perceived need. RESULTS: The percentage of respondents who reported suicide ideation was 3.6%; 74% of them had a probable psychiatric disorder for which effective treatments exist. Nearly half of those with suicide ideation did not perceive a need for care, including some who received care. Of those with suicide ideation and a probable disorder, almost 40% received no treatment. Of those with suicide ideation who perceived a need for alcohol, drug or mental health (ADM) care, almost 40% received no care or inadequate care. In a multivariate model, having a probable psychiatric disorder, perceived need and being white were associated with increased likelihood of treatment use, among persons with suicide ideation. CONCLUSIONS: Many adults with suicide ideation do not perceive a need for care or receive treatment in the same year. Even among those perceiving a need for care, many experience difficulties in obtaining it. It is critical to understand barriers to treatments for this high-risk group.

Prenatal detection of cardiac anomalies in fetuses with single umbilical artery: diagnostic accuracy comparison of maternal-fetal-medicine and pediatric cardiologist.

AIM: To determine agreement of cardiac anomalies between maternal fetal medicine (MFM) physicians and pediatric cardiologists (PC) in fetuses with single umbilical artery (SUA). METHODS: A retrospective review of all fetuses with SUA between 1999 and 2008. Subjects were studied by MFM and PC, delivered at our institution, and had confirmation of SUA and cardiac anomaly by antenatal and neonatal PC follow-up. Subjects were divided into four groups: isolated SUA, SUA and isolated cardiac anomaly, SUA and multiple anomalies without heart anomalies, and SUA and multiple malformations including cardiac anomaly. RESULTS: 39,942 cases were studied between 1999 and 2008. In 376 of 39,942 cases (0.94%), SUA was diagnosed. Only 182 (48.4%) met inclusion criteria. Cardiac anomalies were found in 21% (38/182). Agreement between MFM physicians and PC in all groups combined was 94% (171/182) (95% CI [89.2, 96.8]). MFM physicians overdiagnosed cardiac anomalies in 4.4% (8/182). MFM physicians and PC failed to antenatally diagnose cardiac anomaly in the same two cases. CONCLUSIONS: Good agreement was noted between MFM physicians and PC in our institution. Studies performed antenatally by MFM physicians and PC are less likely to uncover the entire spectrum of cardiac abnormalities and thus neonatal follow-up is suggested.
