In late June, 2024, two economists, Zarek Brot-Goldberg and Zack Cooper, from the College of Chicago and Yale respectively, launched an financial evaluation arguing that hospital mergers harm native economies and end in a rise in deaths by suicide and drug overdoses within the markets the place mergers happen. Funded by Arnold Ventures their research characterizes these mergers as “hire searching for actions” by hospitals searching for to make use of their financial energy to extort monetary features from their communities with out offering any worth.
The Brot-Goldberg-Cooper evaluation was a spin-off of a bigger research decrying the dearth of federal anti-trust enforcement relating to hospital mergers. These two research used the identical financial mannequin. The info had been derived from the Healthcare Price Institute, a repository of business insurance coverage claims info from three of the 4 largest business well being insurers, United Healthcare, Humana and Aetna (a subsidiary of struggling pharmacy big CVS) plus Blue Cross/Blue Defend. HCCI’s contributors account for 28% of the business medical health insurance market.
The authors use a fancy econometric mannequin to govern an enormous, multifactorial knowledge base comprising hospital merger exercise, employer well being advantages knowledge, county degree employment knowledge and morbidity and mortality statistics. This knowledge mannequin enabled a raft of regression analyses making an attempt to ferret out “associations” between the assorted domains of those knowledge.
Utilizing HCCI’s knowledge, the authors assemble what they termed a “causal chain” main from hospital mergers to neighborhood harm throughout their research interval–2010 to 2015. It regarded like this: hospital mergers elevate costs for personal insurers-these costs are handed on to employers–who reply by shedding staff–a few of whom find yourself killing themselves. So, in line with the logic, hospital mergers kill folks. Utilizing the identical methodology, the authors argued that between 2007 and 2014, hospital worth will increase of all kinds killed ten thousand folks.
A traditional drawback with correlational research of this type is their failure to make clear the route of causality of information components. The mannequin lacked a management group–comparable communities that didn’t expertise hospital mergers throughout this era–as a result of the authors argued that mergers had been so pervasive they may not find comparable communities that didn’t expertise them.
The mannequin targeted on a subset of 304 hospital mergers from 2010 to 2015, culled from a universe of 484 mergers nationally throughout the identical interval. The authors excluded mergers of hospitals that had been additional than fifty miles aside, in addition to hospitals with low census. The impact of those assumptions was to exclude most rural hospitals and focus the mergers studied in metropolitan areas and cities. The densest cluster was within the I-95 hall between Washington DC and Boston. See the map beneath:
In keeping with the mannequin, these mergers resulted in a median enhance of 1.2% in hospital costs to business insurers, 91% of which had been handed to their employer clients in these markets. This minuscule price enhance had a curiously targeted and outsized impact–a $10,584 enhance within the median employer’s well being spending within the merged hospitals’ market.
In keeping with the mannequin, native employers “responded” to this value enhance by lowering their payrolls by a median quantity of $17,900, all via layoffs–70% greater than the alleged merger value enhance. This massive overage was not defined by the authors. Furthermore, the layoffs came about virtually instantly, in the identical 12 months because the merger-induced will increase, although many medical health insurance contracts are multi-year affairs, and lock hospitals in to charges for that interval.
On the finish of the “causal chain,” 1 in 140 laid off folks in these communities for no matter purpose killed themselves via suicide or drug overdoses. By extrapolation, the authors accuse the perpetrators of general hospital price will increase of killing ten thousand folks within the affected communities throughout seven years overlapping the research interval.
Failing the Take a look at of Actual World Plausibility
It’s tough to know the place to start to unravel this complicated net of “associations”. The largest puzzle is the magnification of influence of a 1.2% “shock”, because the authors time period it, to well being advantages value on employers. To place this in in perspective, the 1.2% common worth enhance is towards a well being profit that quantities to about 9%, on common, of the pattern employers’ complete compensation prices.* So, 1.2% enhance of a 9% value is an precisely one tenth of 1% (.001) enhance in employer’s complete compensation expense. Payroll and advantages are in flip maybe 50-70% of an employer’s complete working expense. A one-tenth of a % enhance in employment prices is a mosquito chunk, not a “shock”.
The authors’ inferred leap from this micro-increase in employer prices to widespread layoffs is indefensible in comparison with actual world managerial conduct. The authors dominated out the obvious value response–cost-shifting to staff by elevating their deductibles or copayments–on the grounds that they discovered no adjustments in Well being Financial savings Account enrollment within the pattern in the course of the 5 12 months research interval. After greater than quadrupling from 2006 to 2011, progress in HSA enrollment levelled off over the last 4 years of the research interval.
But employer value shifting to staff by elevating their out-of-pocket spending limits accelerated throughout the identical interval. In keeping with Kaiser/HRET’s annual survey, from 2010 to 2015, the variety of staff with deductibles and co-insurance greater than $2,000 doubled. Thus, the results of any business medical health insurance price will increase, no matter their measurement, had been probably shared broadly throughout the whole coated inhabitants within the merger-affected markets.
Most employers going through financial challenges bend over backwards to keep away from parting firm with productive, skilled staff. They usually have a variety of choices to keep away from doing so: elevating costs, reducing hourly staff’ hours, shifting staff from workers to contractors (dodging advantages bills altogether), pressuring different suppliers for reductions, enhancing productiveness, discovering new clients, and “shrinkflation” of their product (e.g. a half-ounce smaller Almond Pleasure bar for a similar worth ). None of those responses had been measured or managed for within the mannequin.
Meager Train of Market Energy
If an anti-competitive train of market energy was the objective of the mergers, then a median 1.2% price enhance struck us as a remarkably meager train of that energy. If merging hospitals had been free to cost what they needed as a result of that they had elevated bargaining energy, why not cost 10% or 20% extra after merging? In keeping with colleagues who work in hospital mergers and acquisitions, transaction prices in a merger can run 3-5% of an acquired hospitals’ annual revenues, and the complicated transaction itself is a large trouble.
A 1.2% post-merger price enhance wouldn’t even cowl the transaction prices of the merger (authorized, accounting and actuarial evaluation, deal brokers and funding banker charges, methods integration consultants to get their completely different “situations” of EPIC to speak and out of doors specialists to help in operational enhancements, and many others), not to mention yield any precise money movement to the merged entity.
What Brought about the Deaths?
As for the ultimate leap -that one in 140 of the employees presumably laid off by these employer reductions in pressure kills themselves or overdose on medication–authors made no traceable efforts to tie these deaths to the businesses allegedly shedding staff. Right here, particularly, the absence of management teams makes it unimaginable to find out how a lot contribution, if any, hospital price will increase or mergers made to the general upward pattern of deaths of despair within the affected communities, versus different related communities.
The authors didn’t management for the opposite components that result in deaths of despair within the goal communities and which may introduce “covariance” error–divorces, deaths of family members, broad-based declines in employment alternatives, closures of church buildings, faculties, or neighborhood based mostly companies, declining availability of psychological well being companies or the sudden arrival of lethal fentanyl within the native market.
Keep in mind the authors intentionally oversampled city markets. Most of the city counties coated within the research (Prepare dinner County-Chicago, Nassau County-Queens, Wayne County-Detroit, Philadelphia County e.gs) are each huge and rife with city poverty. To tie deaths of despair in these troubled communities to hospital mergers is an egregious case of victim-blaming. The identical forces that result in deaths of despair–the lack of financial alternative and social assist–are those harming their hospitals and resulting in their mergers or closure.
What Brought about the Mergers within the First Place?
I’m an skilled in hospital technique. In 1980, I wrote a guide referred to as Can Hospitals Survive, which predicted a lot of the following consolidation within the business. In my forty 12 months consulting profession, I labored for greater than a dozen struggling hospitals that needed to retain their independence. In my lengthy business expertise, hospital boards and medical staffs don’t willingly give up their autonomy and historic id except pressured to by financial circumstances.
The truth is most hospital mergers aren’t actually mergers in any respect, they’re acquisitions of a poorly performing impartial hospital or system by a bigger hospital or well being system. No much less an authority on hospital financing than MedPac Chair Michael Chernew discovered that larger ranges of Medicare funding as a proportion of complete predispose hospitals to failure and, subsequently, merger. An extreme focus of Medicaid and uninsured sufferers has an much more adversarial influence. Price shifting to employers, and charging these employers extra is the one means economically challenged hospitals can get well their losses. The authors didn’t measure or assess the position that adversarial payor-mix adjustments performed in hospital price will increase, or analyze its position in inflicting hospitals to merge. They tried, unsuccessfully in my view, to regulate for failing native economies as a reason behind mergers, employer layoffs and deaths of despair by excluding low census hospitals from their merger evaluation in addition to excluding most rural hospital mergers. However many hospitals which are failing are full of publicly funded sufferers whose protection pays 85% or much less of their precise prices, or of sufferers with no insurance coverage in any respect.
Merger or Closure: The Actual Alternative Dealing with Communities
Most significantly for my part, the authors made no effort to check the results of a merger to that of the lack of the hospital itself. Hospitals are sometimes the neighborhood’s largest employer. The authors estimate that merger-induced price will increase elevate the unemployment price within the native market across the merged hospital by maybe a tenth of a proportion level.
In contrast, hospital closure in a rural neighborhood can elevate the unemployment price by 1.6 proportion factors–that may be a sixteen-fold better impact. Measuring the unemployment impact in small or massive metropolitan labor markets is more difficult however the results of hospital closure can run into the numerous lots of of jobs misplaced, not counting the “multiplier” results on suppliers, business companions and neighboring companies.
Whether or not saving these hospitals was well worth the worth paid by a post-merger price enhance is the real-world coverage query. Although this proposition wants empirical testing, I consider that almost all communities would willingly commerce a 1.2% medical health insurance price enhance for avoiding the lack of their hospital. Excluding the low census hospitals from their regression runs was the authors’ failed try and keep away from discussing this tradeoff.
Whatever the situation of the mergee, the authors made a whopping worth judgment in assuming that that the 1.2% common post-merger price enhance was merely extortion, borne of elevated market leverage, not the worth paid for persevering with that hospital’s operations locally. The authors additionally made no effort to measure post-merger service enhancements, corresponding to elevated doctor retention or recruitment, administration or capital enhancements or different tangible advantages.
Although some research the authors cite fail to seek out value discount or high quality advantages accruing from hospital mergers, more moderen analyses (for roughly the identical research interval as Cooper’s) discovered convincing proof {that a} stronger working accomplice leads to a statistically important drop in prices (-2.5%) per adjusted admission at acquired hospitals, which is in line with the hospitals gaining economies of scale post-merger. There was additionally statistically important decline (-3.9%) in income per adjusted admission, which casts doubt upon the ‘mergers result in larger costs’ speculation.
Adequacy of Hospital Capability a Urgent Concern
Through the 1970’s, federal well being coverage in United States targeted on controlling the availability of hospitals and hospital beds within the US, believing that efforts to fill empty beds had been a serious driver of well being value progress, then in double digits. On the time of Can Hospitals Survive, 30% of hospitals had been already a part of methods. Since that point, almost a thousand hospitals have closed, and the proportion of hospitals which are a part of multi-hospital methods has grown to 70% or higher. Hospital inpatient utilization measured by hospital days per thousand has fallen by half since 1980.
In comparison with the Well being Planning statute’s goal of 4 acute care beds per thousand, at the moment the US is at 2.3 beds per thousand. The US now has the twenty sixth lowest ratio of hospital beds to inhabitants of the 28 OECD international locations. Through the pandemic, many communities skilled important shortages of hospital ICU beds, ER capability, and many others. and had been housing sufferers requiring intensive medical companies in tents within the car parking zone.
Confronted with a selection between merging struggling hospitals into bigger methods and dropping these hospitals–each their service capability and their employment–via hospital closure, the US doesn’t have a margin of error. If the surviving multi-hospital well being methods can not show measurable advantages not solely to acquired hospitals but additionally for the communities they serve, there are going to be severe repercussions for the way forward for Medicare and for the nation’s well being.
This leap from a one-tenth of 1 % enhance in employment prices to widespread layoffs and deaths within the affected markets calls into query not solely authors’ methodology but additionally their objectivity. Probably the most charitable clarification for this odd concentrate on layoffs is what behavioral economists name “affirmation bias,” the unconscious tendency all of us need to ignore knowledge or relationships that don’t verify pre-existing expectations.
Investigators succumbing to affirmation bias have a tendency to seek out what they got down to discover.
A much less charitable clarification is that the authors discovered what their funders (e.g. Arnold Ventures) anticipated them to seek out, given the investigators’ previous analysis findings and the funder’s desired coverage conclusion, that anti-competitive conduct damages native economies and must be reined in.
In both case, a rigorous seek for precise causes is circumvented, and readers are misled.
Nobel Laureate economics Ronald Coase as soon as mentioned: “When you torture knowledge lengthy sufficient, it can confess to something.” That maxim appeared absolutely related to the evaluation of merger impacts now we have been discussing. For my part as a very long time participant/observer of the hospital consolidation course of, the authors made no contribution no matter to fixing the issue of find out how to guarantee entry by struggling communities to hospital companies, nor making these companies extra inexpensive to these communities’ residents. Really working in these communities is a helpful antidote towards being hypnotized by econometric fashions. Blaming hospital mergers for damaging their communities’ economies and killing its residents shouldn’t be solely a gratuitous insult to the concerned hospitals and their boards, it additionally strikes us no nearer to a sustainable well being system going ahead.
