Abstract

OBJECTIVE:

To determine the healthcare utilization and medical care costs of women with a history of intimate partner violence (IPV) compared to women without a history of IPV.

DESIGN:

Longitudinal cohort study.

SETTING:

Mixed-model health maintenance organization.

PARTICIPANTS:

Over 3000 (3333) women aged 18 to 64 years with > or = 3 year's cumulative enrollment prior to the survey, at least 1 year of which was after the 18th birthday.

MAIN EXPOSURE:

IPV since age 18 as determined from responses to telephone interview using questions from the Behavioral Risk Factor Surveillance System and also the Women's Experience with Battering Scale.

OUTCOME MEASURES:

Healthcare utilization and costs (from automated data) during the time that IPV occurred and following its cessation, compared to healthcare utilization for women who did not report IPV since age 18.

RESULTS:

A total of 1546 women reported IPV in their lifetime; at the time of interview, IPV had ceased in 87% of women, on average 16.0 years prior to interview. Healthcare utilization was higher for all categories of service during IPV compared to women without IPV, and decreased over time after cessation of IPV. However, healthcare utilization was still 20% higher 5 years after women's abuse ceased compared to women without IPV. Adjusted annual total healthcare costs were 19% higher in women with a history of IPV (amounting to $439 annually) compared to women without IPV. Based on prevalence for IPV of 44%, the excess costs due to IPV are approximately $19.3 million per year for every 100,000 women enrollees aged 18-64.

CONCLUSIONS:

Women with a history of IPV had significantly higher healthcare utilization and costs, continuing long after IPV ended. Given its high prevalence, IPV has a major impact on medical care resource utilization and efforts to prevent its occurrence and consequences are clearly indicated.
