Standing-up COVID-19 monoclonal antibody infusion centers: Infection prevention and control.

This paper describes the creation of outpatient monoclonal antibody (mAb) infusion centers for COVID-19 patients in a large academic medical center. It shows how the early and consistent partnership between infection prevention and the clinical and operational teams to establish and implement policies and procedures led to efficient and safe workflows.

Use of YouTube by academic medical centres during the COVID-19 pandemic: an observational study in Taiwan.

OBJECTIVES: YouTube has been of immense importance in conveying essential information on COVID-19 and promoting the latest healthcare policies during the outbreak. However, there have been few studies that have focused on how healthcare organisations have used YouTube to communicate with the public and increase their awareness during the pandemic, as well as its effectiveness. DESIGN: A nationwide observational study. SETTINGS: We analysed all YouTube video posts culled from the official accounts of all medical centres in Taiwan from December 2019 to August 2021. PARTICIPANTS: All YouTube videos were categorised as either COVID-19 or non-COVID-19 related. The COVID-19-related videos were divided into five categories, and detailed metrics for each video were recorded. For comparison, we also surveyed all YouTube video posts placed by the Ministry of Health and Welfare and the Taiwan Centers for Disease Control (TCDC). RESULTS: We analysed official YouTube channels from 17 academic medical centres, involving a total of 943 videos. We found a relationship between the quantity of YouTube videos uploaded by the TCDC and the trend of confirmed cases (Pearson's correlation coefficient was 0.25, p=0.02). Data from private hospitals revealed that they posted more COVID-19 videos (103 vs 56) when compared with public hospitals. In addition, multivariate linear regression showed that more 'likes' (estimate 41.1, 95% CI 38.8 to 43.5) and longer lengths (estimate 10 800, 95% CI 6968.0 to 14 632.0) of COVID-19-related videos correlated significantly with an increased number of 'views'. CONCLUSIONS: This nationwide observational study, performed in Taiwan, demonstrates well the trend and effectiveness of academic medical centres in promoting sound healthcare advice regarding COVID-19 through YouTube due to the channel's easy accessibility and usability.

Using a Claims-Based Frailty Index to Investigate Frailty, Survival, and Healthcare Expenditures among Older Adults Hospitalized for COVID-19 at an Academic Medical Center.

BACKGROUND: Frailty is associated with mortality in older adults hospitalized with COVID-19, yet few studies have quantified healthcare utilization and spending following COVID-19 hospitalization. OBJECTIVE: To evaluate whether survival and follow-up healthcare utilization and expenditures varied as a function of claims-based frailty status for older adults hospitalized with COVID-19. DESIGN: Retrospective cohort study. PARTICIPANTS: 136 patients aged 65 and older enrolled in an Accountable Care Organization (ACO) risk contract at an academic medical center and hospitalized for COVID-19 between March 11, 2020 - June 3, 2020. MEASUREMENTS: We linked a COVID-19 Registry with administrative claims data to quantify a frailty index and its relationship to mortality, healthcare utilization, and expenditures over 6 months following hospital discharge. Kaplan Meier curves and Cox Proportional Hazards models were used to evaluate survival by frailty. Kruskal-Wallis tests were used to compare utilization. A generalized linear model with a gamma distribution was used to evaluate differences in monthly Medicare expenditures. RESULTS: Much of the cohort was classified as moderate to severely frail (65.4%), 24.3% mildly frail, and 10.3% robust or pre-frail. Overall, 27.2% (n=37) of the cohort died (n=26 during hospitalization, n=11 after discharge) and survival did not significantly differ by frailty. Among survivors, inpatient hospitalizations during the 6-month follow-up period varied significantly by frailty (p=0.02). Mean cost over follow-up was $856.37 for the mild and $4914.16 for the moderate to severe frailty group, and monthly expenditures increased with higher frailty classification (p <.001). CONCLUSIONS: In this cohort, claims-based frailty was not significantly associated with survival but was associated with follow-up hospitalizations and Medicare expenditures.

Challenges in Use of Practice-based Research Networks for a Medical Device Trial to Detect SARS-CoV-2.

INTRODUCTION/OBJECTIVES: Primary care practice-based research networks (PBRNs) participated in a point of care (POC) device study funded by by the National Institutes of Health and led by the University of Massachusetts Chan Medical School (UMass) to speed the development, validation, and commercialization of POC tests to detect SARS-CoV-2. The purposes of this study were to describe the characteristics of participating PBRNs and their respective collaborators in this device trial and describe complications challenging its execution. METHODS: Semi-structured interviews were conducted with lead personnel from participating PBRNs and UMass. RESULTS: Four PBRNs and UMass were invited to participate and 3 PBRNs and UMass participated. This device trial recruited 321 subjects in 6 months; 65 subjects from PBRNs. Each PBRN and the academic medical center site enrolled and recruited subjects differently. Main challenges identified were having adequate clinic personnel to enroll and aid in consent and questionnaire completion, frequently changing inclusion/exclusion criteria, use of the digital electronic data collection platform, and having access to a -80°C freezer to store supplies. DISCUSSION: This trial involved numerous researchers, primary care clinic leaders and staff, and academic center sponsored program staff and attorneys resulting in a resource-intensive endeavor to enroll 65 subjects in the real-world clinical setting of primary care PBRNs with the academic medical center enrolling the rest. Multiple obstacles to standing up the study were encountered by the PBRNS. CONCLUSIONS: Primary care PBRNs rely largely on the goodwill established between academic health centers and participating practices. For future investigations involving device studies, collaborating PBRN leaders should assess whether recruitment criteria may change, obtain detailed lists of equipment needed, and/or know if the study is likely to be halted suddenly to appropriately prepare their member practices.

Severe Increase in Nursing Labor Cost and Effect on Surgical Department Financial Margins at an Academic, Tertiary Medical Center.

BACKGROUND: A pre-existing nationwide nursing shortage drastically worsened during the pandemic, causing a significant increase in nursing labor costs. We examined the financial impact of these changes on department of surgery financial margins. STUDY DESIGN: Operating room, inpatient, and outpatient financial metrics were analyzed. Monthly averages from a 14-month control cohort, January 2019 to February 2020 (pre-COVID-19), were compared with a 21-month cohort, March 2020 to November 2021 (COVID-19). True revenue and cost data from hospital accounting records, not estimates or administrative projections, were analyzed. Statistics were performed with standard Student's t -test and the Anderson-Darling normality test. RESULTS: Monthly surgical nursing costs increased significantly, with concomitant significant decreases in departmental contribution to margin. No significant change was observed in case volume per month, length of stay per case, or surgical acuity, as standardized by the US Centers for Medicare & Medicaid Services Case Mix Index. To obviate insurance payor mix as a variable and standardize cost data, surgical nursing expense per relative value unit was analyzed, demonstrating a significant increase. Hospital-wide agency nursing costs increased from $5.1 to $13.5 million per month (+165%) in 2021. CONCLUSIONS: Our results demonstrate a significant increase in surgical nursing labor costs with a resultant erosion of department of surgery financial margins. Use of real-time accounting data instead of commonly touted administrative approximations or Medicare projections increases both the accuracy and generalizability of the data. The long-term impact of both direct costs from supply chain interruption and indirect costs, such as limited operating room and ICU access, will require further study. Clearly this ominous trend is not viable, and fiscal recovery will require sustained, strategic workforce allocation.

Year two of virtual interviews: longitudinal changes and diverse perspectives.

BACKGROUND: The coronavirus disease (COVID-19) pandemic brought the virtual interview (VI) format to graduate medical education (GME) and the trainee recruitment process. It is unclear if applicants' VI experience is consistent across all demographic groups. Our group collected 2 years of survey data to assess longitudinal changes in applicants' attitudes towards the VI format. In addition, demographic data were collected, and analyses were performed to identify if between-group differences were present amongst a diverse applicant population. METHODS: We distributed an anonymous electronic survey to applicants to the pulmonary disease and critical care medicine fellowship programs at Case Western Reserve University/University Hospitals Cleveland Medical Center and MetroHealth Medical Center for the 2021 and 2022 appointment years. RESULTS: We received 112 responses (20% response rate) for our surveys. Although there was an overall stability of responses between the first 2 years, there were significant gender differences with applicants identifying as female more likely to recommend VI as a future model. Similarly, there were a significant difference in factor importance based on underrepresented minority (URM) status with applicants identifying as URM placing more emphasis on programs' social media presence. CONCLUSIONS: There were no significant change in the responses of applicants between the first 2 years of VI. However, subset analyses revealed multiple significant findings. These differences have implications for future iterations of the VI format.

Comparison of the prevalence of SARS-CoV-2 nucleoprotein antibodies in healthcare workers and an unselected adult and paediatric all-comer patient population: insights from a longitudinal study of healthcare workers and concurrent serial cross-sectional studies of patients at an academic medical centre in Austria.

OBJECTIVES: This study aimed to estimate and compare the prevalence of the virus-specific antibodies against the SARS-CoV-2 nucleoprotein antigen (anti-SARS-CoV-2 N) in healthcare workers and an all-comer paediatric and adult patient population. DESIGN, SETTING AND PARTICIPANTS: A longitudinal study enrolling healthcare professionals and concurrent serial cross-sectional studies of unselected all-comer patients were conducted at an Austrian academic medical centre. Healthcare workers were tested at enrolment and after 1, 2, 3, 6 and 12 months. The cross-sectional studies in patients were conducted at three time periods, which roughly coincided with the times after the first, second and third wave of SARS-CoV-2 in Austria (ie, 24 August-7 September 2020; 8-22 February 2021 and 9-23 November 2021). Anti-SARS-CoV-2 N antibodies were measured using a sandwich electrochemiluminescence assay (Roche). RESULTS: In total, 2735 and 9275 samples were measured in 812 healthcare workers (median age: 40 years, 78% female) and 8451 patients (median age: 55 years, 52% female), respectively. Over the entire study period, anti-SARS-CoV-2 N antibodies were detected in 98 of 812 healthcare workers, resulting in a seroprevalence of 12.1% (95% CI 10.0% to 14.5%), which did not differ significantly (p=0.63) from that of the all-comer patient population at the end of the study period (407/3184; 12.8%, 95% CI 11.7% to 14.0%). The seroprevalence between healthcare workers and patients did not differ significantly at any time and was 1.5-fold to 2-fold higher than the number of confirmed cases in Austria throughout the pandemic. In particular, there was no significant difference in the seroprevalence between paediatric and adult patients at any of the tested time periods. CONCLUSION: Throughout the pandemic, healthcare staff and an adult and paediatric all-comer patient population had similar exposure to SARS-CoV-2.

Clinical and Proteomic Correlates of Plasma ACE2 (Angiotensin-Converting Enzyme 2) in Human Heart Failure.

ACE2 (angiotensin-converting enzyme 2) is a key component of the renin-angiotensin-aldosterone system. Yet, little is known about the clinical and biologic correlates of circulating ACE2 levels in humans. We assessed the clinical and proteomic correlates of plasma (soluble) ACE2 protein levels in human heart failure. We measured plasma ACE2 using a modified aptamer assay among PHFS (Penn Heart Failure Study) participants (n=2248). We performed an association study of ACE2 against ≈5000 other plasma proteins measured with the SomaScan platform. Plasma ACE2 was not associated with ACE inhibitor and angiotensin-receptor blocker use. Plasma ACE2 was associated with older age, male sex, diabetes mellitus, a lower estimated glomerular filtration rate, worse New York Heart Association class, a history of coronary artery bypass surgery, and higher pro-BNP (pro-B-type natriuretic peptide) levels. Plasma ACE2 exhibited associations with 1011 other plasma proteins. In pathway overrepresentation analyses, top canonical pathways associated with plasma ACE2 included clathrin-mediated endocytosis signaling, actin cytoskeleton signaling, mechanisms of viral exit from host cells, EIF2 (eukaryotic initiation factor 2) signaling, and the protein ubiquitination pathway. In conclusion, in humans with heart failure, plasma ACE2 is associated with various clinical factors known to be associated with severe coronavirus disease 2019 (COVID-19), including older age, male sex, and diabetes mellitus, but is not associated with ACE inhibitor and angiotensin-receptor blocker use. Plasma ACE2 protein levels are prominently associated with multiple cellular pathways involved in cellular endocytosis, exocytosis, and intracellular protein trafficking. Whether these have a causal relationship with ACE2 or are relevant to novel coronavirus-2 infection remains to be assessed in future studies.

Building a National Framework to Pair Scientists and Schools During a Global Pandemic.

The coronavirus disease 2019 (COVID-19) pandemic forced the suspension of in-person education in schools serving students in kindergarten through 12th grade (K-12) across the United States. As time passed, teachers, students, and parents struggled with remote education. With limited guidance at the federal level, physicians and school leaders across the country collaborated to develop local solutions for schools. This article describes the lessons learned from the development of 4 academic-community partnerships and collaboration among these partnerships to provide national leadership on managing COVID-19 mitigation in the K-12 environment. In addition, we describe a pathway forward for using academic-community partnerships to improve child health.

Evaluation of a COVID-19 convalescent plasma program at a U.S. academic medical center.

Amidst the therapeutic void at the onset of the COVID-19 pandemic, a critical mass of scientific and clinical interest coalesced around COVID-19 convalescent plasma (CCP). To date, the CCP literature has focused largely on safety and efficacy outcomes, but little on implementation outcomes or experience. Expert opinion suggests that if CCP has a role in COVID-19 treatment, it is early in the disease course, and it must deliver a sufficiently high titer of neutralizing antibodies (nAb). Missing in the literature are comprehensive evaluations of how local CCP programs were implemented as part of pandemic preparedness and response, including considerations of the core components and personnel required to meet demand with adequately qualified CCP in a timely and sustained manner. To address this gap, we conducted an evaluation of a local CCP program at a large U.S. academic medical center, the University of North Carolina Medical Center (UNCMC), and patterned our evaluation around the dimensions of the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework to systematically describe key implementation-relevant metrics. We aligned our evaluation with program goals of reaching the target population with severe or critical COVID-19, integrating into the structure of the hospital-wide pandemic response, adapting to shifting landscapes, and sustaining the program over time during a compassionate use expanded access program (EAP) era and a randomized controlled trial (RCT) era. During the EAP era, the UNCMC CCP program was associated with faster CCP infusion after admission compared with contemporaneous affiliate hospitals without a local program: median 29.6 hours (interquartile range, IQR: 21.2-48.1) for the UNCMC CCP program versus 47.6 hours (IQR 32.6-71.6) for affiliate hospitals; (P<0.0001). Sixty-eight of 87 CCP recipients in the EAP (78.2%) received CCP containing the FDA recommended minimum nAb titer of ≥1:160. CCP delivery to hospitalized patients operated with equal efficiency regardless of receiving treatment via a RCT or a compassionate-use mechanism. It was found that in a highly resourced academic medical center, rapid implementation of a local CCP collection, treatment, and clinical trial program could be achieved through re-deployment of highly trained laboratory and clinical personnel. These data provide important pragmatic considerations critical for health systems considering the use of CCP as part of an integrated pandemic response.

Cross-Institutional Evaluation of the Abbott ARCHITECT SARS-CoV-2 IgG Immunoassay.

OBJECTIVE: To describe a cross-institutional approach to verify the Abbott ARCHITECT SARS-CoV-2 antibody assay and to document the kinetics of the serological response. METHODS: We conducted analytical performance evaluation studies using the Abbott ARCHITECT SARS-CoV-2 antibody assay on 5 Abbott ARCHITECT i2000 automated analyzers at 2 academic medical centers. RESULTS: Within-run and between-run coefficients of variance (CVs) for the antibody assay did not exceed 5.6% and 8.6%, respectively, for each institution. Quantitative and qualitative results agreed for lithium heparin plasma, EDTA-plasma and serum specimen types. Results for all SARS-CoV-2 IgG-positive and -negative specimens were concordant among analyzers except for 1 specimen at 1 institution. Qualitative and quantitative agreement was observed for specimens exchanged between institutions. All patients had detectable antibodies by day 10 from symptom onset and maintained seropositivity throughout specimen procurement. CONCLUSIONS: The analytical performance characteristics of the Abbott ARCHITECT SARS-CoV-2 antibody assay within and between 2 academic medical center clinical laboratories were acceptable for widespread clinical-laboratory use.

Mitigation Tactics Discovered During COVID-19 with Long-Term Report Turnaround Time and Burnout Reduction Benefits.

RATIONALES AND OBJECTIVES: The purpose is to describe a hybrid teleradiology solution utilized in an academic medical center and its outcomes on radiology report turnaround time (RTAT) and physician wellness. MATERIALS AND METHODS: During coronavirus disease 2019, we utilized an alternating teleradiology solution with procedural and education attendings working in the hospital and other faculty remote to keep the worklist clean. RTAT data was collected for remote vs. in house emergency department (ED) and inpatient cases over a 6-month period. Pre and post implementation burnout surveys were administered. RESULTS: RTAT significantly improved for ED and inpatient MR and CT, and inpatient US and radiographs when interpreted remotely compared to in-hospital. Physician wellness scores improved and open-ended comments reflected positive feedback about the hybrid work solution. 74% enjoyed the autonomy and flexibility, and 51% said the solution positively influences my desire to remain in my current institution and improves their clinical and/or academic productivity. CONCLUSION: Hybrid work from home solutions allow faculty autonomy and flexibility with work-life balance, improving wellness. It is important to alternate the at-home faculty to maintain interdepartmental relations, particularly for junior faculty, and prevent isolation. The hybrid solution also demonstrated improved patient care metrics, possibly due to decreased distractions at home compared to the reading room.

Oxygen-Saturation Targets for Critically Ill Adults Receiving Mechanical Ventilation.

BACKGROUND: Invasive mechanical ventilation in critically ill adults involves adjusting the fraction of inspired oxygen to maintain arterial oxygen saturation. The oxygen-saturation target that will optimize clinical outcomes in this patient population remains unknown. METHODS: In a pragmatic, cluster-randomized, cluster-crossover trial conducted in the emergency department and medical intensive care unit at an academic center, we assigned adults who were receiving mechanical ventilation to a lower target for oxygen saturation as measured by pulse oximetry (Spo₂) (90%; goal range, 88 to 92%), an intermediate target (94%; goal range, 92 to 96%), or a higher target (98%; goal range, 96 to 100%). The primary outcome was the number of days alive and free of mechanical ventilation (ventilator-free days) through day 28. The secondary outcome was death by day 28, with data censored at hospital discharge. RESULTS: A total of 2541 patients were included in the primary analysis. The median number of ventilator-free days was 20 (interquartile range, 0 to 25) in the lower-target group, 21 (interquartile range, 0 to 25) in the intermediate-target group, and 21 (interquartile range, 0 to 26) in the higher-target group (P = 0.81). In-hospital death by day 28 occurred in 281 of the 808 patients (34.8%) in the lower-target group, 292 of the 859 patients (34.0%) in the intermediate-target group, and 290 of the 874 patients (33.2%) in the higher-target group. The incidences of cardiac arrest, arrhythmia, myocardial infarction, stroke, and pneumothorax were similar in the three groups. CONCLUSIONS: Among critically ill adults receiving invasive mechanical ventilation, the number of ventilator-free days did not differ among groups in which a lower, intermediate, or higher Spo₂ target was used.

Effectiveness of Virtual Residency Interviews: Interviewer Perspectives.

BACKGROUND AND OBJECTIVES: Virtual residency interviews were widely utilized during the COVID-19 pandemic. Little is known about the effectiveness, advantages, barriers, and acceptability of virtual interviews, casting uncertainty about how interviews should be conducted after the pandemic. We conducted a survey of interviewers to inform future decisions. METHODS: We developed and implemented an online postinterview survey of interviewers representing seven residency programs and two clinical psychology programs at one midsized academic medical center. We analyzed results using descriptive statistics. RESULTS: Of 312 interviewers, 136 completed the survey (44% response rate). A majority rated virtual interviews as very or extremely effective in creating a comfortable setting (79%), answering interviewee questions (86%), establishing a sense of connection (59%), evaluating interviewee strengths (64%), and communicating program culture (51%). About half felt virtual interviews were not effective at all or only slightly effective for evaluating interviewee strengths via informal interactions (51%). A similar portion agreed or strongly agreed that virtual tours (44%) and social environment (50%) information were adequate. The most frequent advantages were time efficiency (81%), reduced carbon footprint (61%) and cost savings (56%). Frequent disadvantages included technological issues (21%) and caregiving duties (18%). Most interviewers (91%) thought some form of virtual interviews should be incorporated postpandemic. CONCLUSIONS: Interviewers found virtual interviews to be effective in most aspects, and identified more advantages than barriers. The vast majority preferred incorporation of virtual interviews in the future. Virtual tours and social activities were areas for improvement.

Healthcare personnel absenteeism, presenteeism, and staffing challenges during epidemics.

OBJECTIVE: Presenteeism is an expensive and challenging problem in the healthcare industry. In anticipation of the staffing challenges expected with the COVID-19 pandemic, we examined a decade of payroll data for a healthcare workforce. We aimed to determine the effect of seasonal influenza-like illness (ILI) on absences to support COVID-19 staffing plans. DESIGN: Retrospective cohort study. SETTING: Large academic medical center in the United States. PARTICIPANTS: Employees of the academic medical center who were on payroll between the years of 2009 and 2019. METHODS: Biweekly institutional payroll data was evaluated for unscheduled absences as a marker for acute illness-related work absences. Linear regression models, stratified by payroll status (salaried vs hourly employees) were developed for unscheduled absences as a function of local ILI. RESULTS: Both hours worked and unscheduled absences were significantly related to the community prevalence of influenza-like illness in our cohort. These effects were stronger in hourly employees. CONCLUSIONS: Organizations should target their messaging at encouraging salaried staff to stay home when ill.
