What are medical devices? they’re the hardware used by surgeons and clinicians in curing, cobbling together, stabilizing, and managing patients’ medical challenges. They cover orthopedics, interventional cardiology, cardiovascular surgery, and neurosurgery. The technologies represented here are collectively known as “physician preference items.” They can account for one-third of overall hospital supply costs and are growing as a percent of total costs according to the Financial Leadership Council of the Advisory Board. They have an FDA-designed life cycle, as shown in the figure.
Robinson identified several factors that cause market failure for value-based purchasing of medical devices:
- Physicians’ weak business relationships with their hospitals;
- Physicians’ strong bonds with medical device companies; and,
- Shifts of surgical facilities to competing sites (e.g., physician-owned heart hospitals).
There’s also lack of price transparency in medical device negotiations and the need for performance data of the devices in real patients (in other words, useful outcomes data).
Robinson found that the “demand side of the market” lacks the price and performance data that would bolster a healthy market and drive a buoyant, high quality supply side of devices. Complicating the market are intermediaries, such as group purchasing organizations and insurance plans that may mis-align incentives and skew the market away from true patient value.
Health Populi’s Hot Points: Among many smart observations of Robinson’s, one is particularly striking: that a hospital’s and medical staff’s ability to adapt to a changing technological environment is a “larger organizational ability to evaluate and improve the many processes of hospital care.”
What could address this misalignment and mis-cuing of the medical device market that would move it toward value-based purchasing? Price transparency; studies into clinical effectiveness comparing existing technologies with new; and rational reimbursement based on the studies. Robinson also suggests transparency of physician relationships with device firms in terms of consulting fees and other financial relationships; and, aligning incentives such that physicians’ clinical services (and not their own pocketbooks) would be rewarded for using the devices with highest patient value.
As medical device spending is a major health cost driver, adopting these strategies could go a long way to reducing the rate of health cost inflation in the U.S.
