Our friends at the Employee Benefits Research Institute (EBRI) have come out with a new study on consumer-directed health that raises far more questions than it answers. The study was published in Health Affairs, but EBRI also offers an extensive appendix with additional information.
The abstract sums up the lessons thusly –
We explored effects of consumer-directed health plans on health care and preventive care use, using data from two large employers — one that adopted a CDHP in 2007 and another with no CDHP. Our study had mixed results relative to expectations. After four years under the CDHP, there were 0.26 fewer physician office visits per enrollee per year and 0.85 fewer prescriptions filled, but there were 0.018 more emergency department visits. Also, the likelihood of receiving recommended cancer screenings was lower under the CDHP after one year and, even after recovering somewhat, still lower than baseline at the study’s conclusion.
The authors seem to be saying that CDHPs aren’t working all that well and are discouraging the use of preventive services. They also suggest that, by discouraging physician office visits, CDHPs may increase the use of emergency departments. They recommend exempting physician office visits from the deductible.
Maybe, but this research is an awfully thin reed to hang such a recommendation on.
