The coronavirus disease 2019 (COVID-19) pandemic has forced hospital administrators to implement various operational changes that will redefine health care delivery for the foreseeable future. As operational leaders prepare for an eventual return to prepandemic patient volume, we must balance competing priorities: non–COVID-19 elective patient volume that positively affects the revenue cycle and maintaining optimal surge capacity for future peaks of COVID-19–related illness.
Prior to the current pandemic, emergency department (ED) boarding was an unfortunate reality across the United States that led to well-documented increases in mortality, length of stay, and overall cost for admitted patients.1 Overcrowding in the midst of a respiratory pandemic is a dangerous proposition that affects both patient and provider safety. Lessons learned from the pandemic must empower hospitals to emerge leaner than before.
Surge preparation for COVID-19 necessitated reallocation of resources by increasing intensive care unit (ICU) capacity and temporarily eliminating elective surgeries.2 In most institutions across the United States, and as seen in recently published data from our own institution, the pandemic caused unforeseen declines in demand for emergency services.3 As we debate strategies to reopen service lines, operational leaders must recognize that decreased patient volume was not the only reason for improved ED efficiency during the pandemic.
Institutional missions, often driven by fiscal priorities, have unintentional consequences on patient throughput. Harvey Fineberg, MD, PhD, chair of the White House’s newly established Standing Committee on Emerging Infectious Diseases and 21st Century Health Threats, previously coauthored a piece in The New England Journal of Medicine titled “Smoothing the Way to High Quality, Safety, and Economy”; it discussed the detrimental effects of misguided institutional priorities to perform as many planned surgeries as possible.4 Hospitals earn more for elective admissions than for patients admitted through the ED; for this reason, in many institutions, elective admissions take priority over emergency patients.5,6 Although hospital-scheduled admissions may increase revenue, when adjusted for patient volume, they are counterintuitively less predictable than admissions arriving through the ED.7 So, as administrators reprioritize revenue-generating elective surgeries, we must remain cognizant that preserving optimal patient flow is critical for safe and effective care of patients with COVID-19.
Achieving equilibrium between operational efficiency and revenue growth requires understanding differences between natural and artificial variability, a concept introduced by Eugene Litvak, PhD, in the early 2000s. The components of natural variability within an institution are largely random and include a patient’s clinical presentation and physician expertise levels. Natural variability cannot be eliminated; it must be optimally managed. Artificial variability, on the other hand, is influenced by the aforementioned institutional priorities including scheduled surgical admissions, nonemergent interventional radiology/cardiac cases, and incoming inpatient transfers.8
Limiting artificial variability is integral to efficient use of hospital capacity. As local economies begin to reopen, patients emerge from quarantine, and elective surgical volume increases, we have already started to experience an uptick in boarding times at EDs across our state. This is not surprising, as surges in artificial variability have negative impacts on ED, operating room (OR), and ICU throughput. Work coauthored by Donald Berwick, MD, MPP, president emeritus at the Institute for Healthcare Improvement and a former administrator of CMS, has shown that high volumes of scheduled surgical cases increase ICU diversions.9 This upstream bottleneck increases the likelihood of ED throughput delays, leading to a ripple effect of consequences, including reduced quality of care and increased mortality.10
Understanding this contrast between types of variability illustrates why the COVID-19 pandemic led to decreased ED boarding: (1) average overall hospital census decreased due to decreased patient volume, (2) system capacity increased due to field hospitals and dedicated inpatient units balanced with smooth discharges of non–pandemic-related cases, and (3) peaks in artificial variability decreased, thereby reducing the magnitude and frequency of bottlenecks. In reviewing quality data from our own ED, we observed a statistically significant decrease in boarding hours when comparing peak months during the COVID-19 pandemic with matched months in prior years. At Beth Israel Deaconess Medical Center, at peak surge, we increased our ICU capacity by 73% of our normal capacity, which also contributed to reduced boarding of ED patients bound for the ICU. From conversations with colleagues across the country, we expect this is a consistent pattern across most institutions.
Given the high likelihood of future COVID-19–related volume peaks, we must use this opportunity to prevent a return to prepandemic levels of overcrowding. We propose several solutions to reducing artificial variability that optimize operational efficiency, patient safety, and fiscal responsibility:
As we look beyond the next few months of this pandemic, we should capitalize on relatively low bed occupancies to optimize our health systems. Improving operational efficiency might be the only tool available to enable the much-needed balance between increasing revenue and protecting patient access to care. A situation in which medical professionals are forced to choose between caring for elective admissions and patients with COVID-19 is simply untenable. As clinicians and health care leaders, we are morally compelled to respond to a new reality.
