This is the main story in a series examining how trends in healthcare ownership are impacting physician practice. Click here for a sidebar on what physician autonomy means today, and here for a sidebar on how private equity in particular is driving employment trends.
Sterling Ransone, Jr., MD, is a third-generation family physician.
But even one generation ago, the practice of medicine was much different.
Though Ransone followed in his father's footsteps as a rural family doctor, he didn't do so in the same shoes.
From 1957 to 1990, his father practiced solo for years, then added a partner, and ultimately returned to a one-doc shop. However, when Ransone finished his residency at a hospital near his Virginia hometown in the mid-90s, he and his wife formed a practice as part of the health system, and started their careers as employed physicians.
"One of my memories that I will never forget was walking into the kitchen listening to my dad and my mom debate having to increase the price of an office visit from $7 to $10," Ransone told 51˶ in an interview in late September, just a few days before beginning his year-long tenure as president of the American Academy of Family Physicians (AAFP). "They were just struggling to justify, but they couldn't see how they could continue to pay the employees, the electricity bill by getting $7 per office visit."
Ransone's parents worried that patients wouldn't show up if they raised the price. But they knew that they couldn't afford to keep the office open if they didn't.
"It's one of those memories that really stuck with me when I came out of residency," Ransone said. "I thought about it a lot."
"I realized that a lot of my training was not business training at all; my training was how to practice medicine," he added. "I didn't feel as confident with the business management aspect of running a practice."
Increasingly, physicians are pursuing a similar path, whether from the get-go, like Ransone, or after experiencing financial or administrative strife. An American Medical Association survey revealed in May that for the first time, the majority of U.S. physicians (50.2%) are now employees -- suggesting the nature of how and where physicians practice is at an inflection point.
That report also showed that the share of physicians who are practice owners dropped to 44%. The statistic represented a drop of almost 10 percentage points from 2012, the AMA said, when 53.2% of doctors were practice owners.
When Ransone completed his residency, about a third of physicians were employed. Currently, about 70% of AAFP's members are employed in some manner. Half of that 70% are employed by a hospital system or a large group. And half are with smaller groups, physician-owned groups, or other entities.
"The number of one- and two-doc shops that we're seeing is probably 10%, or so," Ransone said.
As for AMGA (formerly the American Medical Group Association), the organization told 51˶ that in 2010, 50% of its members were independent medical groups, and 50% were integrated with a health system. Ten years later, in 2020, about 25% of AMGA's members were independent medical groups, and 75% were integrated with a health system.
Physicians as well as economic experts agree that consolidation, financial pressures, changing generational perspectives, and the pandemic will continue to drive and accelerate the trend toward employment. But that doesn't mean an industry-wide shift to one way of practice is what's best for doctors and patients.
"We need to keep an environment where all forms of practice are viable so that we can give our patients the best service they can have," Ransone said.
In order to do so, experts told 51˶ that more attention must be paid to the factors that are driving down the number of independent physicians.
The Big Are Getting Bigger
The concept of sprawling entities expanding their reach isn't new. But, lately, it's gained more steam.
"This has been going on for probably 40 years," said Joseph Sellers, MD, president of the Medical Society of the State of New York. "There has been a change from physicians working in solo practice into group practices, into larger groups, and into groups affiliated or groups owned by a health system, similar to the consolidation of our hospitals from individual hospitals into systems."
In fact, as of this year, the nation's top eight health systems, ranked by number of affiliated clinicians, boasted more than 20,000 providers each (these figures can include nurse practitioners and physician assistants).
Also, the top 25 health systems, ranked by net patient revenue, raked in annual revenues ranging from more than $11 billion to $44 billion. And the largest hospital within each of the top 5 systems pulled in no less than $1 billion.
Hospitals and health systems are constantly looking for ways to increase their leverage in the marketplace, Glenn Melnick, PhD, a healthcare economist at the University of Southern California, told 51˶.
"They're going to do whatever they can to continue to expand their market share in the region, so that when they sit down with [a major insurer] they've got more leverage," Melnick said.
"What that inadvertently means is, to the extent that you're an independent doc, they're going to be doing things that are going to reduce the flow of patients to you, so that patients go to their doctors," he added. "That's going to put more pressure on independent docs."
In July, President Biden to encourage competition in the American economy. In the order, Biden acknowledged that, due to unchecked mergers, the 10 largest health systems control a quarter of the market, and that hospitals in consolidated markets charge far higher prices than those in markets with several competitors.
The FTC has also from insurers and health systems to study the effects of physician practice mergers and hospital acquisitions of physician practices.
"The policymakers are starting to turn their guns towards these issues," Melnick said. "Most of these organizations are winning because the rules are too easy to create market power."
New Bosses: Insurers, Private Equity
However large they may be, health systems aren't the only entities eyeing medical groups and services. The interest has extended to private equity firms, insurers, and contract management groups (CMGs).
For private equity firms, that means maximizing the rate of return on their investments.
"They don't care if it's razor blades or cancer patients," Melnick said.
Though many physicians have acknowledged a need for investment, they've also remained wary when it comes to private equity. They've questioned whether boosting revenues and cutting costs could have a deleterious impact on how they provide patient care. (See sidebar on the impact of private equity in healthcare.)
Additionally, physicians may want to consider the potential threat of monopsony buyers of their services, whether that comes from large health systems or consolidated groups under private equity, Melnick said.
"If there are fewer and fewer entities that control the flow of dollars into my specialty, there eventually could be like a single payer -- instead of government, it's a private entity," Melnick said. "And they're not going to give me a raise next year."
Insurers are also employing physicians, with the most well-known example being United Health Group's Optum subsidiary, which .
Melnick said insurers investing in medical services can make sense from an economic perspective. For example, it can give insurers more control over their financial outlays.
"The worry is [if] they get control of a local market's physician supply are they going to use that to disadvantage competing health plans," Melnick said. "I control all the docs in the county -- I give myself a good price and I charge all the other plans 30% more." Then, "within a couple years, their premiums are going to be way above mine, and I'm going to control the insurance market."
"That's one worry about that vertical integration -- whether it can contaminate other pieces of the market," he said.
On the other hand, if an insurer "runs medical groups efficiently, then it gives them a low-cost benchmark," Melnick said. "And if they run most of their patients through there, it keeps their premiums low, and that's good for everybody."
Other entities circling the market have included CMGs, or staffing firms, which are often backed by private equity.
Emergency medicine physicians in particular, are "increasingly employed through these large, national contract medicine groups," said Mercy Hylton, MD, MBA, an emergency physician in central Indiana. "But there are many other hospital-based specialties -- like anesthesia, hospitalists, intensivists -- that are being bought up by CMGs."
"The reason why CMGs are beating out small groups is because they have economics of scale to lower their overhead costs, their administrative costs," said Hylton, who is also a board member of the advocacy group Physicians for Patient Protection.
"And," from a physician standpoint, "very often they use some questionable staffing practices," Hylton added.
That has included the utilization of non-physician practitioners, such as nurse practitioners, physician assistants, and certified registered nurse anesthetists, she said.
Access to Capital
When it comes to what is driving physicians toward affiliation or integration with larger entities, including health systems, "Number 1 on the list is access to capital," Jerry Penso, MD, MBA, president and CEO of AMGA, told 51˶.
Physician groups need capital for strategic investments to stay competitive in the future, Penso said. They need money to invest in information technology, population health, equipment, and facilities, he said. And they need a partner for that.
"If the move to value-based, risk-based contracts continues, they need reserves if they're going to take on downside risk," Penso said.
Physicians also look to hospital partners for billing, contracting supply chain management, and to help with operational issues, he added. The independent groups that want to move to the next level -- especially if they want to make additional investments -- need a "more robust infrastructure that would be present in most large systems."
Jonathan Slotkin, MD, chief medical officer at Contigo Health -- part of healthcare improvement company Premier -- and a neurosurgeon at Geisinger, concurred.
Slotkin reiterated that the ongoing shift to value-based care has increased the need for new digital technologies, and compliance and adherence, all of which are expensive and federally mandated, and need to be maintained over time.
Those are things that large health systems are just better at doing at scale than smaller providers, Slotkin said.
