Addressing the Labor Challenge in Healthcare: An Overview
One of the major concerns top players in the healthcare market like UnitedHealth Group Inc. (NYSE:UNH), CVS Health Corporation (NYSE:CVS), and Eli Lilly and Company (NYSE:LLY) are facing are gross labor shortages, primarily due to a surge in early retirements post the pandemic. This new shift in the labor pool puts enormous pressure on hospitals and healthcare providers, especially since skilled medical professionals are critical in processing and carrying out exorbitant amounts of medical and surgical procedures to deal with some of the leading causes of death in the world. According to a report by BlackRock, 1 in 5 healthcare workers in the US have quit their jobs since the onset of the pandemic. 2 out of 3 of those who have quit decided to forego the industry entirely and set up shop elsewhere. This is an enormous dent to the healthcare industry as staffing challenges are having adverse impacts on the production, development and distribution of medical devices and supplies. The declining number of medical professionals available to use advanced medical devices for surgical procedures and other complex medical care have resulted in a depreciation of demand for more advanced product lines. Although the report predicts that the current labor crisis has reached its peak and will settle in the coming years, healthcare companies like UnitedHealth Group Inc. (NYSE:UNH), CVS Health Corporation (NYSE:CVS), and Eli Lilly and Company (NYSE:LLY) will be needing to look out for opportunities and areas of potential to gain strategic advantages over their competitors in an already tight market environment.

The Value in Consumer Centricity: An Analysis
According to a report by McKinsey, the concept of consumer centricity is garnering increasing traction in nearly all consumer-facing industries, with healthcare being no exception. In this vein, top players in the industry like UnitedHealth Group Inc. (NYSE:UNH), CVS Health Corporation (NYSE:CVS), and Eli Lilly and Company (NYSE:LLY) are confronting an imperative of catering to skyrocketing demand and shifting consumer preferences across the end-to-end healthcare journey, in addition to feeling the need to mirror the experiences consumers most enjoy about interacting with other companies. According to research by McKinsey, consumers express greater satisfaction with respect to healthcare they received in the past and have exhibited increasing frustration over the state of the industry today. Healthcare companies are struggling to adopt more consumer-centric practices to try to change this perception owing to core industry dynamics and a swiftly transforming care and coverage landscape.
According to the article, addressing the dynamic nature of consumer expectations and preferences is an incredibly challenging task in that it demand reimagining traditional healthcare journey offerings. To shift current perceptions, healthcare providers could target a future with a dramatically healthier population, with more affordable healthcare, and timely access to the kind of care they require. Healthcare companies like UnitedHealth Group Inc. (NYSE:UNH), CVS Health Corporation (NYSE:CVS), and Eli Lilly and Company (NYSE:LLY) are already diverting increased investments in improving performance through a more affordable product and service lineup, higher-quality care and experiences, an increase in the number of consumers catered to, and more encouraging and incentivizing more consumer loyalty to their improved brands. Furthermore, these companies are making additional efforts to identify customer pain points to unlock improved outcomes, especially with respect to the leading causes of death in the world. According to the report, consumers who are satisfied with their healthcare providers report deferring care more than 10% less, seek out routine care 14% more, and opt for inpatient care options 13% less than unsatisfied customers. Additionally, consumers who have higher levels of engagement tend to persist with their current insurer and provider.
Certain companies have been able to deliver distinctive and innovative solutions at scale which cater to the dynamic nature of consumer preferences better and drive additional value for the health system at large. One such area where companies are investing is in transparent healthcare billing. Nearly all consumers point to the payment experience as one of the most important factors in deciding which healthcare provider to opt for or persist with. Industry innovators have built on the billing journey by prioritizing cost transparency throughout the healthcare experience and by integrating a payer-provider dynamic to encourage a seamless and personalized payment process. One industry leader reported an 88% patient satisfaction and a 30% average lift in patient payments after incorporating the aforementioned mechanisms into their daily operations. Companies like UnitedHealth Group Inc. (NYSE:UNH), CVS Health Corporation (NYSE:CVS), and Eli Lilly and Company (NYSE:LLY) have begun to divert greater investments in delivering customized, at-home care plans via digital pathways to improve upon consumer empowerment and enhance engagement. In a case study conducted by JF Bailey in 2020, more than 75% of consumers enrolled in a company's comprehensive musculoskeletal digital care program experienced considerable reductions in pain and a more seamless healthcare experience.
