Canary in a Coal Mine? A Look at Initial Data on COVID-19’s Impact on U.S. Hospitals

hospital during COVID
  • U.S. hospitals experienced a decline in first-quarter revenue and profitability as a result of the COVID-19 pandemic, a new study shows

  • Hospital declines in service volumes, profits, and market value since the pandemic began could indicate trouble on the horizon for other health systems

  • Issue: During the first three months of the COVID-19 pandemic, hospitals faced significant financial and operating pressure due to their necessary response to the public health crisis. In addition to incurring increased expenses to prepare for and treat COVID-19 patients, hospitals lost revenue for care that was canceled, postponed, or forgone. The federal government has responded with emergency financial relief, but state and federal policymakers still struggle to understand the magnitude of the impact on hospitals because of limited data on hospital financial metrics during the pandemic.
  • Goal: To understand the impact of COVID-19 on hospital utilization, revenue, and profitability.
  • Methods: Study of quarterly financial disclosures, earnings calls, and stock performance of the four largest publicly traded for-profit hospital systems.
  • Key Findings: Admissions, surgeries, and emergency department visits of the four for-profit hospital systems dropped 20 percent to 40 percent during the last two weeks of March 2020 and 30 percent to 70 percent in April 2020. Their first quarter operating profits dropped 13.5 percent (though remained positive), and their market value dropped 52 percent from February 3 to March 18, 2020.
  • Conclusion: COVID-19 affected hospital systems’ revenue and profitability. The necessity of providing congressional relief to hospitals remains ambiguous and varies with individual systems.


To help hospitals adjust to the financial pressures caused by the COVID-19 pandemic, Congress has provided $175 billion in financial relief to hospitals and other providers through the Coronavirus Aid, Relief, and Economic Security (CARES) Act and the Paycheck Protection Program and Health Care Enhancement Act.1 In addition, the CARES Act, among other things, authorized a 20 percent increase in Medicare payments for COVID-19 patients. The two acts were designed to help hospitals adjust to higher expenses and lost revenue, given the concern that hospitals were cancelng elective procedures at the same time they were spending more on personal protective equipment, testing, ventilators, and additional treatment capacity.

When Congress was making relief fund allocation decisions, the operational and financial impact of COVID-19 on U.S. hospitals was unknown. To date, there are only projections,2 estimations,3 anecdotal evidence,4 and survey results from some hospitals.5 To better understand the financial impact on hospitals, we studied evidence from the four largest publicly traded for-profit hospital systems: HCA Healthcare (HCA), Tenet Healthcare Corporation (Tenet), Community Health Systems, Inc. (CHS), and Universal Health Services, Inc. (UHS). We chose to look at these publicly traded for-profit systems because they are required to report financial information on a timely basis. While our sample is not representative of all hospitals, it provides timely empirical data long before any national hospital financial information has become available, and because they must conform to nationally accepted accounting standards, the data are not subject to the response bias that potentially exists in survey studies.

HCA, Tenet, CHS, and UHS are the only four companies in the acute hospital care industry that were publicly listed on May 8, 2020. Combined, they have 88,638 beds and account for approximately 13 percent of the U.S. private hospital market share and 68 percent of the for-profit hospital market share6 (Exhibit 1). Between April 21 and May 4, the four systems filed first-quarter (Q1) 2020 10-Q forms, the Security and Exchange Commission’s mandatory quarterly financial disclosure for all publicly traded companies in the United States. They also conducted quarterly conference calls to explain past earnings and performance, provide future prognostications, and answer questions from the investment community. These call transcripts provided information on performance and specific actions the hospital systems had taken.


Impact on Service Volume

One aim of the congressional funding for hospitals was to provide financial relief for lost revenues due to COVID-19. Thirty states and the District of Columbia issued executive orders requiring that elective procedures be canceled or postponed.7 Patients, concerned about possible COVID-19 infection, are also limiting hospital visits. Compared with the same period in 2019, admissions, surgeries, and emergency department (ED) visits at HCA declined substantially in the last two weeks of March 2020 (20%, 26%, and 30%, respectively), and the decline intensified in April (30%, 63%, and 50%, respectively). Tenet reported similar trends. CHS reported a 70 percent drop in surgeries in April, and UHS had a 29 percent decline in admissions in the first quarter of 2020 (Exhibit 2).

Impact on Revenue, Expenses, and Profit

All hospital systems reported revenues, three components of operating expenses (salary and compensation, supplies, and other operating expenses), and operating profit (revenue minus the sum of the three components of operating expenses). While all four hospital systems maintained positive operating profits in Q1 2020, their aggregated operating profits dropped by 13.5 percent (Exhibit 3). Compared to Q1 2019, HCA, CHS, and UHS experienced little change in revenue in Q1 2020, but saw increases in salary and compensation expenses, supply expenses (not UHS), and other operating expenses. Tenet had a 10.4 percent decrease in revenue and reduced all three components of operating expenses. In the conference call, Tenet attributed its $83 million drop in operating profit to COVID-19, suggesting that during the last few weeks of March, COVID-19 caused a $125 million operating loss.

Impact on Cash and Cash Equivalents

Another aim of congressional funding was to provide liquidity for hospitals’ cash flows. We used the amount of cash and cash equivalents to assess liquidity. Cash equivalents refer to short-term securities with high liquidity and credit quality, such as treasury bonds, commercial papers, and money market funds. We found that for-profit hospital systems took preemptive actions to improve liquidity. The total cash and cash equivalents of the hospital systems increased by 42 percent between Q4 2019 and Q1 2020, from $1.2 billion to $1.6 billion. Except for UHS, all systems increased their cash positions (Exhibit 4). These changes were unrelated to any federal financial relief pertaining to COVID-19 provided to these hospitals. Tenet reduced capital expenditures by $300 million, borrowed $700 million in secured loans, and raised its revolving credit commitment by $400 million. HCA and UHS suspended stock repurchases and dividend payments.

Impact on Stock Performance

We also analyzed the impact of COVID-19 on the stock prices of the four for-profit systems compared to other U.S. companies. To do this, we calculated the combined market value of the four systems and compared it against the S&P 500 Index, which is widely used to indicate the overall stock market, and the Vanguard Health Care Index Fund (Health Care Index), which represents the overall health care sector and is heavily weighted to pharmaceuticals, biotechnology, and health care equipment. We also reviewed financial media reports to understand their perception of the relationship between stock price volatility and major events related to COVID-19.

The stock prices of the hospital systems appear to have responded to government actions and key COVID-19 related news (Exhibit 5):

  • From February 3 to March 18, the combined market value of the four hospital systems dropped by 52 percent, substantially greater than the Health Care Index (20%) or the S&P 500 Index (26%).
  • On the evening of March 18, the second major COVID-19 relief package was signed into law.8 The next day, the Health Care Index and the S&P 500 Index stayed stable, but the market value of the four hospital systems increased by 23 percent.
  • On April 8, Dr. Anthony Fauci, director of the Institute of Allergy and Infectious Diseases, announced that new COVID-19 cases were approaching their peak.9 The hospital systems’ market value increased by 10 percent on that day, but the Health Care Index and the S&P 500 Index increased by only 3 percent and 4 percent, respectively.

As of May 8, the Health Care Index and the S&P 500 Index had largely recovered all of their value relative to that of February 3 (101% and 90%). However, the market value of the hospital systems was still only at 75 percent of their February 3 level.

Study Limitations

First, we only provided evidence of four large for-profit hospital systems. For-profit hospitals are located disproportionately in southern states and outside of urban areas, which have the greatest concentration of COVID-19 patients. They also differ from other types of hospitals in various aspects,10 such as service mix11 and responsiveness to external changes.12 Second, the financial information obtained from Form 10-Q does not differentiate domestic operations from international operations. In our analysis, we were unable to exclude any finances connected with overseas hospitals that these hospital systems may have. Third, stock prices reflect all signals available to the market; thus, the specific impacts of COVID-19 and the effect of government actions or other events on stock prices cannot be accurately quantified.


The mandatory financial disclosure of for-profit hospital systems provides important signals about the impact of COVID-19 on U.S. hospitals — the canary in the coal mine. While the hospitals studied are not nationally representative and many are located outside of COVID-19 hotspots, their declines in service volumes, profits, and market value as a result of COVID-19 are likely to be seen in other health systems.

The necessity of congressional relief for providers remains ambiguous, however. Hospital systems, when possible, have taken proactive measures to maintain cash positions and limit spending. Different systems have varying solvency risks and access to capital. The allocations of relief funds have been based on metrics such as revenue, expenses, or admissions,13 without considering individual hospitals’ financial vulnerability or profitability. None of the hospitals studied reported operating losses during the time period studied, which may not be the case in other geographies and hospitals serving different patient populations. As a result, hospitals in more precarious positions might not receive sufficient funds to remain viable after the pandemic, while hospitals with strong financial resilience might receive substantial support.
