Emergency physicians may be taken out of the workforce because of respiratory symptoms or pending severe acute respiratory syndrome coronavirus 2 test results. Vulnerable emergency physician populations with increased risk of serious disease and death from COVID‐19 include physicians at older ages; those with chronic medical conditions, including cardiac and pulmonary diseases and immunosuppression; and potentially pregnancy. We present our approach to planning for staffing issues through precision scheduling. We describe the actions taken to protect our vulnerable physicians and maximize our physician coverage. Measures include optimizing workforce; increasing backup call system; adjusting shifts based on patient arrival times, volume, and surge predictions; minimizing exposure to COVID‐19 and reduce personal protective equipment use through telemedicine, huddles, and, creating lower risk emergency department care areas; and standardizing intubations to limit exposure. for COVID-19 from unprotected exposure or repeated exposure; risk can be mitigated with personal protective equipment (PPE) measures. 4 Prolonged exposure to patients with COVID-19 directly increased the risk of infection in healthcare workers. 5 With respiratory pandemics, emergency physicians are also at increased risk of transmission from aerosolizing procedures such as intubation. [6] [7] [8] Approximately 3.2% of patients with COVID-19 will require intubation from respiratory failure. 9 We present precision scheduling concepts and strategies that can be used to optimize the emergency physician workforce and minimize exposure to patients with COVID-19. We provide a general concept that is illustrated by a specific example from our ED followed by suggestions for precision scheduling in other ED settings. A subpopulation of emergency physicians are at increased risk for serious disease and death from COVID-19 as a result of older age, comorbid conditions including being immunocompromised, and potentially pregnancy. Approximately 34.8% of emergency physicians in the United States are older than 55 years of age. 10 In the United States, among patients with COVID-19, fatality increased with age. 11 Adults with chronic medical conditions are at increased risk of severe disease from COVID-19. A meta-analysis demonstrated that hypertension, respiratory diseases such as chronic obstructive pulmonary disease, and cardiovascular disease were the leading comorbidities in severe cases of COVID-19 compared with non-severe cases. 12 which was consistent with county-wide positivity data. 14, 15 The percentage of ED patients who tested positive for SARS-CoV-2 and were admitted to the hospital ranged from 8%-46% with a mean and median of 27%. By temporarily adjusting and decreasing our ED staffing, we minimized the number of physicians exposed to patients with COVID-19. APPs in the hospital can be flexed to meet hospital and department needs. Before the epidemic, 1-2 APPs primarily staffed the ED observation unit. At that time, the hospital policy excluded PUIs and patients positive for SARS-CoV-2 from being admitted to the ED observation unit. The lower ED volume led to decreased census in the ED observation unit. The second APP was re-assigned to see low-acuity patients in the ED area that had the least number of emergency physician residents. APPs who typically work other parts of the hospital can be trained to work in areas in the hospital that are impacted by COVID-19 such as the ED and inpatient wards. Given the uncertainty of the COVID-19 surge, the emergency medicine residency made several adjustments to the resident staffing and curriculum. Similar to the attendings, emergency medicine residents with fever or respiratory symptoms regardless of exposure to patients with COVID-19 were considered PUIs and had to be tested by occupational health before returning to work. The emergency medicine residency activated the backup call resident 3 times more than usual during the first month of the pandemic. Resident staffing was decreased to minimize the number of physicians in the ED. Emergency medicine residents with cancelled shifts were placed on the backup call schedule. Emergency medicine residents were reassigned to work in areas to maximize their skills. The emergency medicine residency program collaborated with other programs less affected by COVID-19. The pediatrics residency and pediatric emergency medicine fellowship covered shifts in the pediatric ED that were previously scheduled for emergency medicine residents. This allowed emergency medicine residents to be available for the anticipated surge of patients with COVID-19 in the adult ED. 16 When the predicted surge did not occur in our local area, the emergency medicine interns were given priority to restart their pediatric ED shifts as soon as possible, and senior emergency medicine residents were incorporated back into the pediatric ED schedule. This period lasted approximately 8-10 weeks of the 4-year emergency physician residency curriculum. In other settings impacted by increased volume of patients with COVID-19, residents from other residency programs may rotate in the ED or staff the inpatient wards and intensive care unit. With increased availability of SARS-CoV-2 testing, the recommendations for testing healthcare professionals broadened, which led to an increased number of emergency physicians considered to be PUIs who had to wait for a negative test to return back to work. To account for the increased backup call activations, it was necessary to build a robust backup call coverage system. Before the pandemic, we had a backup emergency attending physician scheduled each day to cover a 24-hour period. The backup call physician could be activated at any time and was expected to be within a 1-hour travel distance from the ED. To Patient volume decreased significantly during the shelter in place, and the number of scheduled shifts were changed based on patient volume. To adjust the shifts, each week we examined hourly arrival and census curves broken down by Emergency Severity Index and by PUI status. The Emergency Severity Index is a 5-level triage tool to classify patients based on patient acuity and expected resource needs. 17 We are able to determine the resources needed each hour of the day based on patient arrivals. We used a 3-day moving average with a day-of-the-week modifier to project the next day's volume. Moving average is a way to analyze trends in data. For the day-of-the-week modifier, we looked at how much that day of the week varied from the average volume from the previous week and applied it to the moving average. In response to these data, we decreased our attending physician schedule from 20 shifts to 14 shifts during the lowest patient volume time period. We removed shifts dedicated to low-acuity areas, including the walk-in clinic, the second attending shift in the pediatric ED, and 1 float/resource shift and closed 1 of the ED areas completely. Physicians with cancelled shifts were placed on a sick-call schedule. We used this information to remove an additional For PUI or patients with COVID-19, we used telemedicine to minimized exposure to healthcare professionals and reduced PPE use. Many of the ED patient rooms had telemedicine capability through the television in the patient room, which was connected to the physician workstation computer. However, many rooms were not equipped with this type of telemedicine. We decided a new telemedicine system was needed, and it took 8 days to implement a new system using iPads and teleconferencing software. An iPad with teleconferencing software was assigned to a meeting room with an auto-answer feature and was placed in each patient room. The iPad gave a notification beep to the patient and a few seconds later connected to the virtual meeting room without the patient having to touch the iPad. A central iPad was located in the physician work area, which could call the iPad in each patient room. Healthcare professionals who entered rooms with PUIs were minimized. In the ED, after a patient had been triaged, the triage nurse who had donned PPE brought the patient into the room and turned on the iPad or the telemedicine software on the room television screen. Residents and attending physicians used these telemedicine options to obtain the initial history from patients as well as update patients on laboratory and radiology results, next steps, and disposition plans without having to go into the room. Patients in isolation rooms only had one physician perform the physical examination portion of the visit. To distribute exposure and reduce PPE usage, the attending and resident alternated who performed the physical examination depending on the size of the team. If the resident performed the examination, the attending watched the resident perform the examination through telemedicine. In EDs that do not have access to iPads or teleconferencing services, another option would be to call the patient's cell phone, the room's intercom system, or use other free video chat services to talk with the patient to minimize the time healthcare professionals are spending in the room when direct patient contact is not required. Physicians and nurses used huddles to minimize the number of times healthcare professionals entered the room. During the huddles, team members discussed orders and potential next steps. Nurses also used telemedicine to communicate with patients or with staff when they needed an item that was not in the room (eg, tube for blood draw, ECG machine). Using these strategies, we estimate that we have reduced daily PPE use by 80-120 sets. Lower risk areas can be created within the ED to reduce exposure to patients with COVID-19. Before the pandemic, all patients regardless of ESI level could be seen in any ED room including respiratory patients. During the pandemic, we clustered patients to create 2 lower risk areas for vulnerable emergency physicians. One area saw lower acuity patients without fever or respiratory symptoms. The second area used telemedicine exclusively to evaluate well-appearing patients who require SARS-CoV-2 testing and was considered a no-risk zone. The no-risk zone was a temporary drive-thru model that was set up in the garage adjacent to the ED for patients who were coming to the ED for SARS-CoV-2 testing only. Residents and attending physicians were asked to self-identify as higher risk for severe illness after COVID-19 exposure using the following criteria: age >65 years, chronic medical conditions or on immunosuppressant medications, or pregnancy. Physicians who were considered higher risk were given the option to be taken off the schedule or to be assigned to work in one of the lower risk areas of the ED. Physicians who were at higher risk for severe illness after COVID-19 exposure were excluded from performing intubations. EDs who are limited by physical space can explore expanding the ED outside of the normal footprint temporarily such as parking lots, waiting rooms, hallways near the ED, medical tents, and so on depending on the rules and regulations of the hospital and local public health department. Standardizing aerosolizing procedures such as intubation reduced Since March 1, 2020, only 2 physicians (1.2%) were diagnosed with COVID-19 of 13 APPs, 62 emergency physician residents, and 88 emergency attending physicians and fellows. These 2 infections occurred in March during the first 3 weeks of the pandemic. The positivity rate in the 2 adjacent counties were 3%-5%. 14,15 The COVID-19 pandemic has created a unique situation and a need to optimize the emergency physician workforce. We present our approach to precision scheduling to maximize our physician coverage and reduce exposure. We optimized APPs, residents, and attending physician coverage in the ED and created a robust backup call system to cover physicians with COVID-19 or those unable to work as a result of testing. We adjusted the number of ED shifts and hours that areas were open based on the patient volume. We minimized exposure to COVID-19 and reduced PPE usage through telemedicine, huddles, and creating new lower risk areas in the ED. We asked physicians to self-identify as being higher risk for severe illness and rescheduled these physicians to work into lower risk areas. A COVID-19 intubation protocol reduced the number of healthcare professionals exposed during aerosolizing procedures. These strategies may be considered by other EDs during the COVID-19 pandemic.
