Adapting Tools to Implement Stroke Risk Management to Veterans (TOOLS)

10. september 2018 oppdatert av: VA Office of Research and Development

The purpose of this study is to develop and evaluate the local adaptation of existing stroke prevention tools into practice. A stroke prevention program is a collection of materials including written materials like pamphlets and brochures, videotapes and training guides for stroke survivors and evidence based guidelines for the doctors that provide care for them. Other tools that may be used in a stroke prevention program include devices that help patients monitor medical symptoms at home like home blood pressure machines or blood sugar monitors and messaging devices that allow reporting symptoms from home to a health care provider.

We hypothesized Veterans with stroke who receive the Veteran Stroke Prevention Program would engage in better medication compliance and stroke specific quality of life compared to those who did not receive the program.

Detaljert beskrivelse

Stroke affects at least 15,000 veterans each year, and this number will likely increase as the veteran population ages. According to the American Heart Association, the prevalence of stroke is expected to double by 2020 with the increased proportion of older adults nationwide. Our preliminary Quality Enhancement Research Initiative work indicates that stroke risk factors are often undermanaged in the Veterans Health Administration.

This proposed study of a stroke risk factor management program may benefit the Veteran Health System in several ways. First, it offers a systematic program for reduction in stroke risk factors leading to better health for our veterans and a reduction in inpatient and outpatient rehabilitation and home health services for these events. Second, the Veteran Stroke Prevention Program takes into account the varied resources and services offered in VAMCs across the nation, allowing the program to be tailored both to a given facility and to the individual veteran's needs and readiness to change. Importantly, the program could allow all VA facilities to offer guideline-concurrent stroke risk reduction programs and therefore increase compliance with VA/Department of Defense, American Heart Association, and the Joint Commission stroke care guidelines and improve their quality of stroke care.

Comparison(s): We will compare two regionally matched facilities on rates of secondary stroke prevention guideline care during the course of the study at the intervention sites.

  • Stroke Specifc, Health Related Quality of Life (SSQoL)
  • Self reported survey by LS Williams Weinberger M, Clark, D, Harris L, Biller J. Development of a stroke specific quality of life scale. Stroke, 1999;30:1362-1369.
  • Contains 12 domains and 49 items Scored on a 5 pt Likert response format with lower score indicating worse function/lower ability on that item or domain. Domain scores were calculated as an unweighted average of item scores in that domain. Overall Total Score was calculated as an unweighted average of domain scores.

We hypothesized the intervention group would report significantly greater stroke specific quality of life than the control group. The level of significance was set to 0.05.
