Hospitals can prepare for a surge of patients critically ill with COVID-19, but it will require hospital leaders, practitioners and regional officials to adopt drastic measures that challenge the standard way of providing care, according to a new RAND Corporation report.
The analysis summarizes a range of evidence-based and promising strategies for creating critical care capacity in the nation’s hospitals, and includes a simple online tool that allows decision-makers at all levels — hospitals, healthcare systems, states and regions — to estimate current critical care capacity and rapidly explore strategies for increasing it.
Because the healthcare system is already stretched close to its limits, creative thinking will be needed to carve out the necessary critical care capacity to address the surge in COVID-19 patients, the analysis found.
It’s based on a review of research about experiences during past outbreaks (including SARS, MERS and others), a survey of front-line clinicians conducted in collaboration with the American College of Emergency Physicians, and two roundtables conducted via conference call with leading emergency and critical care physicians and public health and preparedness experts from around the country.
WHAT’S THE IMPACT
The research identified two tiers of activities that hospitals can take to expand critical care capacity.
The first tier includes strategies to expand critical care capacity without significantly impacting the ability to provide other medical care. Those approaches include things such as acquiring additional ventilators from stockpiles — which is much easier said than done — and converting some operating rooms to critical care units.
The second tier focuses on crisis capacity strategies that are likely to significantly impact routine care delivery and operations. This might include turning regular hospital beds into critical care beds and re-opening shuttered hospitals. It also includes items such as changing staffing and supervisory ratios, altering standards of care.
To illustrate the possible impact of the strategies on capacity, researchers used publicly available data on the 10 Federal Emergency Management Agency Regions to estimate the number of patients that could be accommodated, given the number of available critical care doctors and nurses, respiratory therapists, ventilators, and beds.
The analysis found the number of ventilators is the most common limiting factor, followed by the number of critical care doctors. The number of nurses, respiratory therapists, or beds were not the limiting factor in any FEMA region.
As expected, the capability to move to higher tiers increases capacity. But the degree of increase in critical care surge depends on both the amount of resources available and the specific combinations. In most situations, the Tier 2 options produce considerably more capacity than Tier 1 options, but in some cases, there is little additional gain.
In the survey of 343 physicians conducted nationally on March 13, the most-cited concerns were shortages in diagnostic kits, a shortage of negative pressure room capacity, and a shortage of N95 masks.
Roundtable participants emphasized the need for real-time information sharing to increase situational awareness of critical care surge capacity among hospitals and across regions.
THE LARGER TREND
In addition to critical care challenges, hospitals are struggling with supply. A survey conducted last week confirmed that most doctors are short on medical supplies and COVID-19 tests, with 73% of physicians saying they can’t treat patients for coronavirus quickly and easily. Close to 60% said there were not enough coronavirus precautions in their clinical setting.
