Much of the public commentary around the U.S. healthcare system is focused on the
role of government and an unsustainable cost trajectory. Politics aside, a more clinical
assessment reveals a number of private sector initiatives underway that are driving
meaningful cost reductions and improving profitability for healthcare companies.
Despite some structural flaws, the healthcare ecosystem provides investment
opportunities with less cyclical cashflows. TCW sees evidence of private sector
innovation shifting the healthcare landscape and presenting opportunity for investors.
Strong Vitals
The U.S. healthcare sector has grown more rapidly than the broader economy,
accounting for 17.9% of GDP as of 2016. While some portion of this growth results
from the demands of an aging population, structural flaws have enabled unchecked
pricing power by some service providers and excessive use of medical services (excess
utilization) by insurance policy holders.

Cost Ailments
Prescription drug costs attract substantial media attention, yet pharmaceuticals
account for only 10% of U.S. health expenditures. Hospitals and physician services,
referred to as “provider care,” are actually the more significant portion of health
spending, accounting for 52% of costs on a combined basis.
The provider care subsectors are plagued by inefficiencies, and thus have invited
innovation and competition.

Market Remedies
Despite industry growth above that of the Consumer Price Index, healthcare cost inflation has actually been decreasing in recent years.

We attribute improvements in the cost trend to several developments from both the payments side and the provider side.
Payer Evolution
On the payments side, publicly traded health insurance companies have grown substantially through mergers and acquisitions.
Facing the problem of above-market cost inflation, these companies have pursued consolidation to achieve economies of scale and to
improve negotiating leverage vis-à-vis hospitals and physicians.
Hospital prices for everything from a simple check-up to a complex surgery are set on a bespoke, negotiated basis. Hospitals maintain
a “charge master” that lists a sticker price for every procedure and diagnosis code. Health insurers must negotiate volume discounts
off of these sticker prices, based on the ability to deliver patients through an approved network arrangement.
Consolidation has gradually improved the relative negotiating leverage of the health insurers, while the provider side of the equation
has remained highly fragmented by comparison.

In addition, the widespread adoption of electronic health records has enabled insurers to more directly address excess
utilization. Real time claims data have enhanced negotiating leverage, and led to interventional measures such as “prior
authorization approvals.”
Health insurance companies have also passed the burden of medical cost inflation onto plan members. The increasing
prevalence of high deductible health plans has cultivated a consumer awareness of the price/value trade-off associated with
medical care. As healthcare becomes more consumer-oriented, we see a rising demand for cheaper and more accessible
treatment options.
This consumer price sensitivity has been met with private sector investment in lower cost, alternative care settings.
Provider Evolution
Advancements in medical technology have allowed many forms of surgery to be safely performed outside of a traditional hospital
setting. Without the fixed costs associated with operating a multi-disciplinary hospital, a stand-alone surgical center can accept
lower prices on a per-procedure basis.
Free standing surgery centers have thus emerged as a lower cost option for many common procedures, putting downward
pressure on aggregate health expenditures.

In addition to surgery centers, substantial investment has been made in urgent care facilities, and retail clinics as well.

Hospital emergency rooms historically faced little competition for the full spectrum of patient volumes. Lack of competition, along
with an implicit subsidy of uninsured patients, resulted in excessive pricing for the treatment of many minor conditions.

In many cases, an urgent care center can provide the exact same treatment as a hospital at only 10%-20% of the cost.

When considering the cost and unpleasant experience associated with a hospital emergency room visit, it is no wonder that a
consumer would opt for an alternative treatment option.
As a result, traditional hospital business models now confront a new paradigm – reduced pricing power and heightened
competition for patients.
A Prescription for Success
TCW sees opportunity in today’s healthcare sector as companies implement effective cost containment strategies. In particular,
TCW continues to have a favorable view of those pursuing an “integrated care” approach, whereby an insurer owns provider-side
assets in order to more holistically manage total healthcare spending.
Various organizations have approached the integrated model in different ways:
- Kaiser Permanente (a non-profit) is the clearest example of a fully formed integrated care organization, owning a health insurer
as well as a full suite of provider assets.
- United Healthcare has approached this from the payer side as well, gradually adding provider assets to help internalize the cost
of care for health plan members.
- HCA and Tenet Healthcare have approached this from provider side origins. As hospital volumes have stagnated, these
companies have added lower cost treatment centers in order to remain competitive.
- Recently announced mergers between CVS Health and Aetna, Humana and Walmart (rumored), and Cigna and Express Scripts
have each sought to add capabilities to more fully serve the healthcare continuum.

While TCW takes a more cautious view of those focused solely on the provider side, we do see enduring demand for differentiated
assets in areas such as oncology and complex surgery. Opportunity remains for providers that are able to distinguish themselves
either through specialization, or by offering lower cost care.
The role of government in the healthcare system is not to be taken lightly, as regulations create operating challenges as well
as barriers to entry. TCW focuses primarily on the economic characteristics of this industry; where a history of innovation and
relatively non-cyclical cashflows can offer solid returns on capital for the careful investor.
