In an effort to assess and reduce gender-related quality gaps, the Veterans Health Administration (VHA) has promoted gender-based research. Historically, such appraisals have often relied on secondary databases, with little attention to methodological implications of the fact that VHA provides care to some nonveteran patients.
To determine whether conclusions about gender differences in utilization and cost of VHA care change after accounting for veteran status.
Cross-sectional.
All users of VHA in 2002 (N = 4,429,414).
Veteran status, outpatient/inpatient utilization and cost, from centralized 2002 administrative files.
Nonveterans accounted for 50.7% of women (the majority employees) but only 3.0% of men. Among all users, outpatient and inpatient utilization and cost were far lower in women than in men, but in the veteran subgroup these differences decreased substantially or, in the case of use and cost of outpatient care, reversed. Utilization and cost were very low among women employees; women spouses of fully disabled veterans had utilization and costs similar to those of women veterans.
By gender, nonveterans represent a higher proportion of women than of men in VHA, and some large nonveteran groups have low utilization and costs; therefore, conclusions about gender disparities change substantially when veteran status is taken into account. Researchers seeking to characterize gender disparities in VHA care should address this methodological issue, to minimize risk of underestimating health care needs of women veterans and other women eligible for primary care services.
为了评估并缩小与性别相关的医疗质量差距,退伍军人健康管理局(VHA)推动了基于性别的研究。从历史上看,此类评估通常依赖二手数据库,很少关注VHA为一些非退伍军人患者提供护理这一事实的方法学意义。
确定在考虑退伍军人身份后,关于VHA护理利用情况和成本的性别差异结论是否会改变。
横断面研究。
2002年VHA的所有用户(N = 4,429,414)。
退伍军人身份、门诊/住院利用情况和成本,数据来自2002年的集中管理档案。
非退伍军人占女性用户(大多数为雇员)的50.7%,但仅占男性用户的3.0%。在所有用户中,女性的门诊和住院利用情况及成本远低于男性,但在退伍军人亚组中,这些差异大幅减小,或者在门诊护理的使用和成本方面出现逆转。女性雇员的利用情况和成本非常低;完全残疾退伍军人的女性配偶的利用情况和成本与女性退伍军人相似。
按性别划分,在VHA中,非退伍军人在女性中所占比例高于男性,一些大型非退伍军人群体的利用率和成本较低;因此,在考虑退伍军人身份后,关于性别差异的结论会发生很大变化。试图描述VHA护理中性别差异的研究人员应解决这一方法学问题,以尽量降低低估女性退伍军人和其他有资格获得初级保健服务的女性的医疗需求的风险。
