Hospital and Healthcare Industry: An Analysis
The hospital market has been growing at an unprecedented rate. The size of hospital industry was $820 billion in 2021 and is anticipated to reach the $2 trillion figure by 2028 with a Compound Annual Growth Rate (CAGR) of 12.5% according to a report published by Facts and Factors. The report highlights aging population, rise in chronic diseases, improved reimbursement policies, advances in medical science and technology as the key drivers of growth in the hospital industry but also stresses that high service charges and operational costs at private hospitals is a limiting factor in the industry’s growth. The report acknowledged the role Covid-19 pandemic could play in widening the increase in hospital market size.
The recent pandemic showed just how important a role hospitals play in the times of emergency, especially when lives are at stake. The role of hospitals as primary care centers was put to the test during the peak Covid-19 waves in 2020. Approximately 4.6 million people were hospitalized in the US due to Covid-19 according to American Hospital Association report of 2022. Hospitals with proper and surplus equipment as well as well-trained staff played a significant role in flattening the curve around the world while many people lost their lives wherever there was shortage of hospital staff or equipment.
However, it is also noteworthy that hospital industry was under significant financial stress in the short term during the height of the pandemic. The hospitals’ management had to form strategies to increase ICU capacity by re-purposing hospital beds and reassigning nurses and clinicians to staff Covid-19 emergency wings either voluntarily or due to government mandates, leading to a decline in treating non-critical medical problems.
This was coupled with expenses related to unbudgeted procurement of Personal Protective Equipment (PPE) to protect staff, overtime-pay for front-line caregivers as well as procurement of surplus drugs and ventilators to care for the desperately ill constantly coming in. By the end of 2021, drug and ICU expenses incurred by hospitals were 28% and 31% higher than pre-pandemic levels respectively according to the American Hospital Association report.
All of the capital spending and laying-off of non-essential staff and hiring of additional essential staff among other measures led to a dramatic decline in profitability. As a result, hospitals had to suffer significant revenue loss and had to cut expenditures in other areas of medical service. The American Hospital Association report highlighted that 33% hospitals were operating on negative margins due to pandemic stress.
However, with the vaccination drive in full swing, hospitals are set to recover to normal operations and hospital companies could soon see significant inflow of investment. In fact, the larger healthcare industry is already performing significantly better than the past couple of years. Its intraday returns on May 13 were at 1.05%.
Pfizer Inc. (NYSE:PFE), Tenet Healthcare Corporation (NYSE:THC) and HCA Healthcare, Inc. (NYSE:HCA) were some of the prominent names that were in the spotlight in the US in the wake of the pandemic. The last two of these are hospital companies that are included in the list of 10 biggest hospital companies in the world.
