For 2016, PwC forecasts a 6.5 percent health spending increase based upon current plan designs, with an alternative 4.5 percent increase after anticipated plan design changes are factored in.

Cost sharing has either been implemented or will be soon, said 85 percent of the employers responding to the survey. Virtual medical care will come into its own next year, the report says, offering another way to contain the cost of care.

But too much cost-sharing will undermine the point of health insurance: to keep employees healthy. More than a quarter of covered employees said they did not seek recommended medical care because they felt their share of the cost was too high.

Thus PwC foresees a shift in cost containment that will balance cost of care to the insured with ensuring that people use insurance to stay healthy, since a healthy population is actually the biggest factor in containing medical care cost escalation.

Here’s the report summary:

“In this year’s report, we identified the following factors expected to “deflate,” or reduce, the healthcare growth rate in 2016:

• Looming “Cadillac tax” accelerates cost shift

• Virtual care

• New health advisers

Going the other way, there are two factors expected to “inflate,” or boost, the spending trajectory in 2016:

• Specialty drugs

• Cyber security

“More Americans with health insurance and an improving economy have not increased the medical spending trajectory. Structural changes have helped keep costs in check. But there is still much to be done as long as health spending continues to outpace gross domestic product and individual consumers and companies struggle to afford services,” the report says.

“Health companies must restrain costs when bringing new cures and technology to consumers. … Employers must pursue strategies that not only strengthen their bottom line but better equip workers to make informed health decisions – or they will all pay a high cost in the long run.
