In an op-ed published Friday on Forbes, Ubel cited a study in the New England Journal which involved 55 Catholic organizations having overhauled their employee health care benefits in 2013.
The organizations used a reference-pricing model to help nudge employees to choose cheaper and equally-effective treatment options.
“The reference pricing plan was hugely influential,” Ubel writes. “The percent of patients choosing the least expensive drug in any particular category of medication rose from around 60% to 70%. By contrast, employees in different companies, who weren’t subject to reference pricing, showed almost no change in purchasing behavior over the same time.”
