This study includes interesting descriptive evidence that suggests that men’s use of the ED decreased to a greater extent than women’s during the period immediately following their employers’ switch from an HMO to an HDHP [high deductible health plan]. The pattern of reduction by sex was also quite different by severity of the visit. Womens’ relative reduction in ED use was concentrated in low-severity visits, whereas men’s relative reductions were similar in magnitude in the low and intermediate category but was markedly higher in the high severity category. In addition, there was an immediate reduction in inpatient hospitalizations in the first year among men who worked for employers who switched to HDHPs, followed by what could be interpreted as a reversion to the preperiod level in the second year.
Naturally, there are a number of limitations of the study, upon which Hoceknberry comments. However, the study’s findings are consistent with a body of evidence that men use health care differently than women. The investigators summarize,
[Men] are less likely to seek and receive needed health care. [10–14] Sex differences in health care utilization are well documented; females use more preventive care and prescription medications than males. [12,15,16] Women also use emergency care with greater frequency  and resource intensity than men.  These discrepancies in care patterns may be partially explained by sex differences in health care needs across the age spectrum, and sex-specific types health care services (reproductive health care, sex-specific cancers, etc.). [14,15] But other factors are also at play. Behavioral and attitudinal differences (such as masculinity beliefs) also influence health care use and health seeking behaviors. [13,17–19]
In light of the evidence, Hockenberry suggests we might observe sex-specific sorting into health plans in the new marketplaces (formerly “exchanges”). Offered plans will vary in their degree of cost sharing and deductible levels, but premiums will not vary by gender within plan. Will men preferentially select higher deductible plans? This is just one of many questions that might be studied when the data start flowing. Who’s on it?
