Changes in health care costs over time following the cessation of intimate partner violence.

BACKGROUND: Research has documented greater health care costs attributable to intimate partner violence (IPV) among women during and after exposure. However, no studies have determined whether health care costs for abused women return to baseline levels at some point after their abuse ceases. OBJECTIVE: We examine whether health care costs among women exposed to IPV converge with those of non-abused women during a 10-year period following the end of exposure. DESIGN: Retrospective cohort analysis. SETTING: Group Health Cooperative, a large integrated health care system in the Pacific Northwest. PARTICIPANTS: Random sample of English-speaking women aged 18-64 enrolled within Group Health and who participated in a telephone survey between June 2003 and August 2005. MEASUREMENTS: Total health care costs over an 11-year period from January 1, 1992 to December 31, 2002 were compiled using automated health plan data and comparisons made among women exposed to IPV since age 18 and those who never experienced IPV. IPV included physical, sexual, or psychological violence involving an intimate partner, and was assessed using five questions from the Behavioral Risk Factor Surveillance System. RESULTS: Relative to women with no IPV history, total health care costs were significantly higher during IPV exposure, costs that were sustained for 3 years following the end of exposure. By the 4th year following the end of exposure to IPV, health care costs among IPV-exposed women were similar to non-abused women, and this pattern held for the remainder of the 10-year study period. CONCLUSIONS: Policy makers should consider the ongoing needs of victims following abuse exposure. Interventions to reduce the prevalence of IPV or to mitigate the impact of IPV have the potential to reduce the rate of growth of health care costs.

Preferred modes of travel among older adults: what factors affect the choice to walk instead of drive?

INTRODUCTION: There are many factors that influence older adults' travel choices. This paper explores the associations between mode of travel choice for a short trip and older adults' personal characteristics. METHODS: This study included 406 drivers over the age of 64 who were enrolled in a large integrated health plan in the United States between 1991 and 2001. Bivariate analyses and generalized linear modeling were used to examine associations between choosing to walk or drive and respondents' self-reported general health, physical and functional abilities, and confidence in walking and driving. RESULTS: Having more confidence in their ability to walk versus drive increased an older adult's likelihood of walking to make a short trip by about 20% (PR=1.22; 95% CI: 1.06-1.40), and walking for exercise increased the likelihood by about 50% (PR=1.53; 95% CI=1.22-1.91). Reporting fair or poor health decreased the likelihood of walking, as did cutting down on the amount of driving due to a physical problem. DISCUSSION: Factors affecting a person's decision to walk for exercise may not be the same as those that influence their decision to walk as a mode of travel. It is important to understand the barriers to walking for exercise and walking for travel to develop strategies to help older adults meet both their exercise and mobility needs. IMPACT ON INDUSTRY: Increasing walking over driving among older adults may require programs that increase confidence in walking and encourage walking for exercise.

Physicians' and women's views on hormone therapy and breast cancer risk after the WHI: a qualitative study.

BACKGROUND: The use of menopausal hormone therapy (HT) has significantly declined since the release of the Women's Health Initiative findings, but to what extent physicians' and women's concerns about breast cancer contributed to this change is unknown. Our study explored physicians' and women's beliefs about hormone therapy and breast cancer risk. METHODS: We conducted qualitative in-depth interviews with 22 primary care physicians and 45 female patients at two large integrated health care delivery systems in Washington State and Massachusetts. RESULTS: Concerns about breast cancer risk weighed into the decision-making process for physicians and women in initiating and continuing hormone therapy. For women, control of menopausal symptoms was important and possibly outweighed their concerns about the potential risks of breast cancer. Though concerned about its association with increasing breast cancer risk, physicians were willing to consider hormone therapy to manage women's menopausal symptoms but were frustrated about the lack of available non-hormone therapy alternatives. Most physicians and some women were aware of the Women's Health Initiative, and its findings appeared to influence their beliefs about hormone therapy and breast cancer risk, though doubts remained among both groups about the study findings and implications. CONCLUSIONS: Our qualitative study suggests that after the Women's Health Initiative, concerns about breast cancer risk weighed into decisions to initiate and continue hormone therapy for both physicians and women, but menopausal symptoms often directed use.

Intimate partner violence among men prevalence, chronicity, and health effects.

CONTEXT: The breadth and depth of intimate partner violence (IPV) experienced by men have not been fully documented. OBJECTIVES: To describe the prevalence, chronicity, and severity of IPV, and the health outcomes associated with IPV, in adult men with healthcare insurance. DESIGN: A retrospective telephone cohort study conducted from 2003 to 2005. The setting was an integrated healthcare system in Washington State and Idaho. PARTICIPANTS: English-speaking men aged 18 and older (N=420) enrolled in the healthcare system for 3 or more years. MAIN OUTCOME MEASURES: Physical, psychological, and sexual IPV were assessed using five questions from the Behavioral Risk Factor Surveillance Survey. Health was measured using the Short Form-36, version 2 (SF-36v2) survey, the Center for Epidemiological Studies Depression Scale, and the National Institute of Mental Health Presence of Symptoms Survey. RESULTS: Men experienced IPV at a rate of 4.6% in the past year, 10.4% in the past 5 years, and 28.8% over their lifetimes. While overall rates of physical and nonphysical IPV were similar, men aged 18-55 were twice as likely to be recently abused (14.2%, SE=2.6%) than were men aged 55 and older (5.3%, SE=1.6%). Abuse was typically nonviolent or mildly violent, occurred on multiple occasions, and was initiated by only one intimate partner. Compared to men with no IPV, older men who experienced IPV had more depressive symptoms (prevalence ratios=2.61 and 2.80 for nonphysical and physical abuse) and had lower SF-36v2 mental health subscales (range=-3.21 to -5.86). CONCLUSIONS: Men experience IPV at moderate rates, and poor mental health outcomes are associated with such experiences.

Health care utilization and costs associated with childhood abuse.

BACKGROUND: Physical and sexual childhood abuse is associated with poor health across the lifespan. However, the association between these types of abuse and actual health care use and costs over the long run has not been documented. OBJECTIVE: To examine long-term health care utilization and costs associated with physical, sexual, or both physical and sexual childhood abuse. DESIGN: Retrospective cohort. PARTICIPANTS: Three thousand three hundred thirty-three women (mean age, 47 years) randomly selected from the membership files of a large integrated health care delivery system. MEASUREMENTS: Automated annual health care utilization and costs were assembled over an average of 7.4 years for women with physical only, sexual only, or both physical and sexual childhood abuse (as reported in a telephone survey), and for women without these abuse histories (reference group). RESULTS: Significantly higher annual health care use and costs were observed for women with a child abuse history compared to women without comparable abuse histories. The most pronounced use and costs were observed for women with a history of both physical and sexual child abuse. Women with both abuse types had higher annual mental health (relative risk [RR] = 2.07; 95% confidence interval [95%CI] = 1.67-2.57); emergency department (RR = 1.86; 95%CI = 1.47-2.35); hospital outpatient (RR = 1.35 = 95%CI = 1.10-1.65); pharmacy (incident rate ratio [IRR] = 1.57; 95%CI = 1.33-1.86); primary care (IRR = 1.41; 95%CI = 1.28-1.56); and specialty care use (IRR = 1.32; 95%CI = 1.13-1.54). Total adjusted annual health care costs were 36% higher for women with both abuse types, 22% higher for women with physical abuse only, and 16% higher for women with sexual abuse only. CONCLUSIONS: Child abuse is associated with long-term elevated health care use and costs, particularly for women who suffer both physical and sexual abuse.

Intimate partner violence and health care costs and utilization for children living in the home.

OBJECTIVE: The goal was to determine whether differences in health care costs and utilization exist for children whose mothers experienced intimate partner violence versus those who did not. METHODS: A longitudinal cohort study was performed in an integrated health care delivery organization with 760 children of mothers with no history of intimate partner violence and 631 children of mothers with a history of intimate partner violence since age 18. Health care utilization and costs for children before, during, and after intimate partner violence exposure were compared with utilization and costs for children with nonabused mothers. RESULTS: Health care utilization and health care costs were higher in most categories of care for children of mothers with a history of intimate partner violence, with significantly higher values for mental health services, primary care visits, primary care costs, and laboratory costs. Children of mothers with a history of intimate partner violence that ended before the child was born had significantly greater utilization of mental health, primary care, specialty care, and pharmacy services than did children of mothers who reported no intimate partner violence. Children exposed directly to intimate partner violence (after birth) had greater emergency department and primary care use during the intimate partner violence and were 3 times as likely to use mental health services after the intimate partner violence ended. CONCLUSIONS: Children whose mothers experienced intimate partner violence have higher health care utilization and costs, even if their mothers' abuse stopped before they were born. Screening of women for intimate partner violence should be a routine part of their health care, and interventions for both the women and their children are likely necessary to minimize the effects of intimate partner violence in the family.

Concordance of population-based estimates of mammography screening.

OBJECTIVE: Estimates of adherence to mammography screening guidelines vary, in part, due to lack of consensus on defining adherence. This study estimated adherence to repeat (two successive on-time screenings) and regular screening (three or more successive screenings) and evaluated the impact of varying operational definitions and evaluation periods. METHODS: The study included women aged 50-80 without a history of breast cancer who: were on a biennial screening cycle and due for a screening mammogram between 1995 and 1996; underwent screening (index date) in response to a reminder letter; and belonged to Group Health, an integrated health care delivery system in Washington State, for 6 or more years after the index date. Automated records provided information on enrollment, health care utilization, and procedures. RESULTS: Among 1336 women, 67-82% experienced a repeat screen. Adherence to regular screening over the 6-year evaluation period was 42-84%--and higher with longer allowable intervals between screenings, when definitions did not require on-schedule screenings, when intervals were reset after a diagnostic mammogram, and for shorter evaluation periods. CONCLUSION: Estimates of adherence to screening guidelines varied by the operational definition of "success" and time period of evaluation. Consensus in definitions and terminology is needed to compare evaluations.

How the Women's Health Initiative (WHI) influenced physicians' practice and attitudes.

BACKGROUND: The landmark Women's Health Initiative (WHI) Postmenopausal Hormone Therapy Trial published in 2002 showed that the health risks of combination hormone therapy (HT) with estrogen and progestin outweighed the benefits in healthy postmenopausal women. Dissemination of results had a major impact on prescriptions for, and physician beliefs about HT. No study has fully examined the influence of the widely publicized WHI on physicians' practice and attitudes or their opinions of the scientific evidence regarding HT; in addition, little is known about how physicians assist women in their decisions regarding HT. DESIGN AND PARTICIPANTS: We conducted in-depth telephone interviews with family practitioners, internists, and gynecologists from integrated health care delivery systems in Washington State (n = 10 physicians) and Massachusetts (n = 12 physicians). Our objectives were to obtain qualitative information from these physicians to understand their perspectives on use of HT, the scientific evidence regarding its risks and benefits, and counseling strategies around HT use and discontinuation. APPROACH: We used Template Analysis to code transcribed telephone interviews and identify themes. RESULTS: Physicians were conflicted about the WHI results and its implications. Seven themes identified from in-depth interviews suggested that the WHI (1) was a ground-breaking study that changed clinical practice, including counseling; (2) was not applicable to the full range of patients seen in clinical practice; (3) raised concerns over the impact of publicized health information on women; (4) created uncertainty about the risks and benefits of HT; (5) called for the use of decision aids; (6) influenced discontinuation strategies; and (7) provided an opportunity to discuss healthy lifestyle options with patients. As a result of the WHI, physicians reported they no longer prescribe HT for prevention and were more likely to suggest discontinuation, although many felt women should be in charge of the HT decision. CONCLUSIONS: Physicians varied in their opinions of HT and the scientific evidence (positive and negative). Whereas the WHI delineated the risks and benefits of HT, physicians reported that decision aids are needed to guide discussions with women about menopause and HT. Better guidance at the time of WHI study publication might have been valuable to ensure best practices.

Self-management aspects of the improving chronic illness care breakthrough series: implementation with diabetes and heart failure teams.

Self-management is an essential but frequently neglected component of chronic illness management that is challenging to implement. Available effectiveness data regarding self-management interventions tend to be from stand-alone programs rather than from efforts to integrate self-management into routine medical care. This article describes efforts to integrate self-management support into broader health care systems change to improve the quality of patient care in the Chronic Illness Care Breakthrough Series. We describe the general approach to system change (the Chronic Care Model) and the more specific self-management training model used. The process used in training organizations in self-management is discussed, and data are presented on teams from 21 health care systems participating in a 13-month-long Breakthrough Series to address diabetes and heart failure care. Available system-level data suggest that teams from a variety of health care organizations made improvements in support provided for self-management. Improvements were found for both diabetes and heart failure teams, suggesting that this improvement process may be broadly applicable. Lessons learned, keys to success, and directions for future research and practice are discussed.
