Infection Prevention Considerations for a Multi-Mission Convention Center Field Hospital in Baltimore, Maryland, During the COVID-19 Pandemic.

The state of Maryland identified its first case of coronavirus disease 2019 (COVID-19) on March 5, 2020. The Baltimore Convention Center (BCCFH) quickly became a selected location to set up a 250-bed inpatient field hospital and alternate care site. In contrast to other field hospitals throughout the United States, the BCCFH remained open throughout the pandemic and took on additional COVID-19 missions, including community severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diagnostic testing, monoclonal antibody infusions for COVID-19 outpatients, and community COVID-19 vaccinations.To prevent the spread of pathogens during operations, infection prevention and control guidelines were essential to ensure the safety of staff and patients. Through multi-agency collaboration, use of infection prevention best practices, and answering what we describe as PPE-ESP, an operational framework was established to reduce infection risks for those providing or receiving care at the BCCFH during the COVID-19 pandemic.

Recruitment, Readiness, and Retention of Providers at a Field Hospital during the Pandemic.

In response to the coronavirus disease 2019 (COVID-19) pandemic, the State of Maryland established a 250-bed emergency response field hospital at the Baltimore Convention Center to support the existing healthcare infrastructure. To operationalize this hospital with 65 full-time equivalent (FTE) clinicians in less than four weeks, more than 300 applications were reviewed, 186 candidates were interviewed, and 159 clinicians were credentialed and onboarded. The key steps to achieve this undertaking involved employing multidisciplinary teams with experienced personnel, mass outreach, streamlined candidate tracking, pre-interview screening, utilizing all available expertise, expedited credentialing, and focused onboarding. To ensure staff preparedness, the leadership developed innovative team models, applied principles of effective team building, and provided 'just in time' training on COVID-19 and non-COVID-19 related topics to the staff. The leadership focused on staff safety and well-being, offered appropriate financial remuneration and provided leadership opportunities that allowed retention of staff.

High Sensitivity and NPV for BinaxNOW Rapid Antigen Test in Children at a Mass Testing Site during Prevalent Delta Variant Period.

SARS-CoV-2 continues to develop new, increasingly infectious variants including delta and omicron. We evaluated the efficacy of the Abbott BinaxNOW Rapid Antigen Test against Reverse Transcription PCR (RT-PCR) in 1,054 pediatric participants presenting to a high-volume Coronavirus Disease 2019 (COVID-19) testing site while the delta variant was predominant. Both tests utilized anterior nares swabs. Participants were grouped by COVID-19 exposure and symptom status. 5.2% of samples tested positive by RT-PCR for SARS-CoV-2. For all participants, sensitivity of the BinaxNOW was 92.7% (95% CI 82.4%-98.0%), and specificity was 98.0% (95% CI 97.0%-98.8%). For symptomatic participants, positive predictive value (PPV) was 72.7% (95% CI 54.5%-86.7%) and negative predictive value (NPV) was 99.2% (95% CI 98.2%-100%). Among asymptomatic participants, PPV was 71.4% (95% CI 53.7%-85.4%) and NPV was 99.7% (95% CI 99.0%-100%). Our reported sensitivity and NPV are higher than other pediatric studies, potentially because of higher viral load from the delta variant, but specificity and PPV are lower. IMPORTANCE The BinaxNOW rapid antigen COVID-19 test had a sensitivity of nearly 92% in both symptomatic and asymptomatic children when performed at a high-throughput setting during the more transmissible delta variant dominant period. The test may play an invaluable role in asymptomatic screening and keeping children safe in school.

Implementation and Accuracy of BinaxNOW Rapid Antigen COVID-19 Test in Asymptomatic and Symptomatic Populations in a High-Volume Self-Referred Testing Site.

Rapid antigen tests are simple to perform and provide results within 15 min. We describe our implementation and assess performance of the BinaxNOW COVID-19 Antigen Test (Abbott Laboratories) in 6,099 adults at a self-referred walk-up testing site. Participants were grouped by self-reported COVID-19 exposure and symptom status. Most (89%) were asymptomatic, of whom 17% reported potential exposure. Overall test sensitivity compared with reference laboratory reverse-transcription [RT] PCR testing was 81% (95% confidence interval [CI] 75%, 86%). It was higher in symptomatic (87%; 95% CI 80%, 91%) than asymptomatic (71%; 95% CI 61%, 80%) individuals. Sensitivity was 82% (95% CI 66%, 91%) for asymptomatic individuals with potential exposure and 64% (95% CI 51%, 76%) for those with no exposure. Specificity was greater than 99% for all groups. BinaxNOW has high accuracy among symptomatic individuals and is below the FDA threshold for emergency use authorization in asymptomatic individuals. Nonetheless, rapid antigen testing quickly identifies positive among those with symptoms and/or close contact exposure and could expedite isolation and treatment. IMPORTANCE The BinaxNOW rapid antigen COVID-19 test had a sensitivity of 87% in symptomatic and 71% asymptomatic individuals when performed by health care workers in a high-throughput setting. The performance may expedite isolation decisions or referrals for time-sensitive monoclonal antibody treatment in communities where timely COVID PCR tests are unavailable.

Lessons Learned From Implementing Rehabilitation at a COVID-19 Field Hospital.

ABSTRACT: Rehabilitation experts play an important role in preventing hospital-acquired debility, increasing patients' abilities to safely perform activities of daily living, and facilitating discharge to the home setting for patients with COVID-19. Surges in COVID-19 hospitalization rates combined with increases in length of hospital stay and decreases in postacute care placements have necessitated the opening of COVID-19 field hospitals around the country. Most field hospitals lack the resources to offer a full suite of rehabilitation services, but there are opportunities for small teams of rehabilitation experts to increase their reach by using innovative strategies. This article describes the implementation of a small team of rehabilitation experts in a COVID-19 field hospital and strategies used by this team to maximize patient activity and mobility, facilitate timely discharge, and maximize the number of patients discharged to the home setting. Strategies include training nonclinical staff to assist with activity and mobility promotion and using a rehabilitation triage system to determine needs of individual patients and facilitate efficient resource utilization. The authors reflect on successful aspects of these strategies, as well as barriers to rehabilitation implementation, and make recommendations for other field hospitals seeking to implement rehabilitation during the COVID-19 pandemic or future health crises.

The Impact of the COVID-19 Pandemic on Elective Inpatient Surgical Admissions: Evidence From Maryland.

BACKGROUND: The COVID-19 pandemic led to large-scale cancellation and deferral of elective surgeries. We quantified volume declines, and subsequent recoveries, across all hospitals in Maryland. MATERIALS AND METHODS: Data on elective inpatient surgical volumes were assembled from the Maryland Health Service Cost Review Commission for years 2019-2020. The data covered all hospitals in the state. We compared the volume of elective inpatient surgeries in the second (Q2) and fourth quarters (Q4) of 2020 to those same quarters in 2019. Analysis was stratified by patient, hospital, and service characteristics. RESULTS: Surgical volumes were 55.8% lower in 2020 Q2 than in 2019 Q2. Differences were largest for orthopedic surgeries (74.3% decline), those on Medicare (61.4%), and in urban hospitals (57.3%). By 2020 Q4, volumes for most service lines were within 15% of volumes in 2019 Q4. Orthopedic surgery remained most affected (44.5% below levels in 2019 Q4) and Plastic Surgery (21.9% lower). CONCLUSIONS: COVID-19 led to large volume declines across hospitals in Maryland followed by a partial recovery. We observed large variability, particularly across service lines. These results can help contextualize case-specific experiences and inform research studying potential health effects of these delays and cancellations.

How We Do It: Modified Residency Programming and Adoption of Remote Didactic Curriculum During the COVID-19 Pandemic.

OBJECTIVE: To describe the modified operational plan we implemented for residents and faculty in our orthopedic surgery department to allow continuation of resident education and other core activities during the novel coronavirus (COVID-19) pandemic. DESIGN: Description of educational augmentation and programming modifications. SETTING: The Johns Hopkins Hospital and Johns Hopkins Bayview Medical Center, Baltimore, MD. PARTICIPANTS: Residents and faculty, Department of Orthopaedic Surgery. METHODS: In response to the COVID-19 pandemic, we developed and implemented a modified operational schedule and remote curriculum in the orthopedic surgery department of our health system. Our plan was guided by the following principles: protecting the workforce while providing essential clinical care; maintaining continuity of education and research; and promoting social distancing while minimizing the impact on team psychosocial well-being. RESULTS: The operational schedule and remote curriculum have been implemented successfully and allow resident education and other core departmental functions to continue as our health care system responds to the pandemic. CONCLUSIONS: We have been proactive and deliberate in implementing these operational changes, without compromise of our workforce. This experience provides residents exposure to real-life systems-based practice. We hope that our early experience will provide a framework for other surgical residency programs facing this crisis.

Departmental Experience and Lessons Learned With Accelerated Introduction of Telemedicine During the COVID-19 Crisis.

Despite the use of digital technology in healthcare, telemedicine has not been readily adopted. During the COVID-19 pandemic, healthcare systems have begun crisis management planning. To appropriately allocate resources and prevent virus exposure while maintaining effective patient care, our orthopaedic surgery department rapidly introduced a robust telemedicine program during a 5-day period. Implementation requires attention to patient triage, technological resources, credentialing, education of providers and patients, scheduling, and regulatory considerations. This article provides practical instruction based on our experience for physicians who wish to implement telemedicine during the COVID-19 pandemic. Between telemedicine encounters and necessary in-person visits, providers may be able to achieve 50% of their typical clinic volume within 2 weeks. When handling the massive disruption to the routine patient care workflow, it is critical to understand the key factors associated with an accelerated introduction of telemedicine for the safe and effective continuation of orthopaedic care during this pandemic.
