Comparative Effectiveness Research and Policy
BACKGROUND AND OBJECTIVE: The Washington State workers' compensation agency funded a coverage with evidence development study to evaluate spinal cord stimulation (SCS) for chronic back and leg pain after spine surgery (failed back surgery syndrome). We previously published the study outcomes. We now report results from a second patient cohort; study costs; and industry, provider, and payer responses. RESEARCH DESIGN, SUBJECTS, AND MEASURES: This …

The nootropic properties of ginseng saponin Rb1 are linked to effects on anxiety
Previous studies have shown that crude ginseng extracts enhance performance on shock-motivated tasks. Whether such performance enhancements are due to memory-enhancing (nootropic) properties of ginseng, or to other non-specific effects such as an influence on anxiety has not been determined. In the present study, we evaluated both the nootropic and anxiolytic effects of the ginseng saponin Rb1. In the first experiment, 80 five-day-old male chicks…
Involving Patients in Clinical Decisions
BACKGROUND: Back surgery rates are rapidly rising in the United States. This surgery is usually elective, so patient preferences are important in the treatment decision. OBJECTIVES: The objective of this study was to determine the impact on outcomes and surgical choices of an interactive, diagnosis-specific videodisk program for informing patients about treatment choices. RESEARCH DESIGN: This was a randomized, controlled trial at 2 sites compari…
Impact of a Worker's Compensation Practice Guideline on Lumbar Spine Fusion in Washington State
OBJECTIVES: In the face of escalating medical costs for injured workers, the Washington State Department of Labor and Industries (L&I), which pays for most workers' compensation costs in the state, established guidelines for elective lumbar fusion as part of its inpatient utilization review program. The guidelines were tied to reimbursement strictures. The authors attempt to assess the effects of these guidelines, which were introduced in Novembe…
The seattle appropriate level of care survey
We surveyed 77 persons with AIDS, their physicians and their social workers during the autumn of 1987 to ascertain health status and to quantify use of health services in Seattle, Washington. Participants included the majority (59%) of persons living with AIDS in the area. Information was gathered regarding demography, health status, functional status, medical history and the use of health services. The validity of self-assessed general health wa…
Variation in the Rate of Cervical Spine Surgery in Washington State
Lack of consensus about the treatment of low back pain is reflected by wide regional variations in lumbar spine surgery rates. Neck pain may be as common as low back pain, but there has been no similar evaluation of regional variation for the surgical treatment of neck pain. This report examines the geographic variation and temporal trends in the rate of cervical spine surgery in Washington state from 1986 through 1989. Using diagnosis and proced…

Strategies for Improving and Expanding the Application of Health Status Measures in Clinical Settings
Health status instruments may be useful in clinical settings to screen for functional problems, monitor disease progression or therapeutic response, improve doctor-patient communications, assess quality of care, or provide case-mix adjustment for comparing other outcomes between patient groups. However, conceptual, practical, and attitudinal barriers have prevented their wider implementation. Aside from providing more data on how these measures i…

Risk factors for suicide attempts among Navajo adolescents
BACKGROUND: Rates of adolescent suicide in the United States are highest among Native Americans but little is known about risk factors for suicide attempts in this population. METHODS: To identify risk factors for self-reported suicide attempts by Navajo adolescents, we analyzed the 1988 Indian Health Service Adolescent Health Survey that was administered to 7,254 students in grades 6 through 12 on the Navajo reservation. The responses of student…
Barriers to the Use of Health Status Measures in Clinical Investigation, Patient Care, and Policy Research
Despite growing interest and sophistication in health status assessment, these measures are not widely used in settings where they would be appropriate. The reasons include conceptual, methodologic, practical, and attitudinal barriers, some of which are common to a variety of applications (e.g., clinical research, patient care, or policy research). These barriers include skepticism about the validity and importance of self-rated health; preferenc…
Generic and Disease-Specific Measures in Assessing Health Status and Quality of Life
Application of generic and specific measures of health status and quality of life to different diseases, conditions, states, and populations is increasing. Four strategies for using these measures are separate generic and specific measures, modified generic measures, disease-specific supplements, and batteries. The preferred strategy depends on project aims, methodological concerns, and practical constraints. Generic measures are necessary to com…
Risk of postmenopausal hip fracture in Mexican American women
To assess the risk of hip fracture in Mexican Americans, the ethnicity of 80 women aged 50 years and over admitted with hip fractures to a Texas hospital was compared with that of age-matched women hospitalized for other reasons. The risk of fracture for Mexican Americans was only 35 per cent that of Whites (95% CI = 19 per cent, 65 per cent). This finding was confirmed in a chart survey performed in a second hospital population. These results su…
A simple language-based acculturation scale for Mexican Americans
A simple scale for quantifying English use among Mexican Americans was constructed from four brief questions which proved to have excellent scaling characteristics by Guttman Scalogram Analysis in two independent data sets. Construct validity was established by significant associations of the scale with ethnicity, place of birth, generation within the United States, and type of neighborhood. Highly significant associations were found between scal…
Pitfalls in measuring the health status of Mexican Americans
We tested a Spanish translation of the Sickness Impact Profile (SIP) in a clinical study of low back pain, which included non-Hispanic patients (Group I), Mexican Americans who used the English SIP (Group II), and Mexican Americans who used the Spanish SIP (Group III). The reliability and clinical validity of responses by these three groups were compared. Internal consistency of responses by all three groups was excellent ( Cronbach 's alpha for …
Measuring Functional Outcomes in Chronic Disease
A new "health-status" questionnaire, the Sickness Impact Profile (SIP), was examined to determine whether it offered measurement advantages over the traditional American Rheumatism Association (ARA) functional scale or patient self-ratings of function. Seventy-nine outpatients with rheumatoid arthritis (RA) administered the SIP to themselves and provided self-ratings on a 7-point functional scale. Clinicians independently rated patients on the AR…
Dropouts and Broken Appointments
Patient dropouts create inefficiencies for medical providers, threaten the validity of clinical research and may themselves suffer unnecessary morbidity. A review of literature concerning patient dropouts and broken appointments was undertaken in an effort to identify correlates of the behavior, assess proposed interventions and identify issues for the content and methodology of future research. While the bulk of existing reports deal with psychi…
