Complementary and alternative medicine use among elderly persons: one-year analysis of a Blue Shield Medicare supplement.

BACKGROUND: Large scale surveys in the United States and abroad suggest that 35-60% of adults have used some form of complementary/alternative medicine (CAM). However, no studies to date have focused on predictors and patterns of CAM use among elderly persons. METHODS: The population surveyed were Californians enrolled in a Medicare risk product that offers coverage for acupuncture and chiropractic care. Surveys were mailed to 1597 members in 1997 and responses received by 728 (51% response rate). Health risk assessment data were also obtained at baseline and 12-15 months following enrollment in the plan. Multiple logistic regression analyses were carried out to examine predictors of CAM use. RESULTS: Forty-one percent of seniors reported use of CAM. Herbs (24%), chiropractic (20%), massage (15%), and acupuncture (14%) were the most frequently cited therapies. CAM users tended to be younger, more educated, report either arthritis and/or depression/anxiety, not be hypertensive, engage in exercise, practice meditation, and make more frequent physician visits. Use of CAM was not associated with any observed changes in health status. Respondents also expressed considerable interest in receiving third-party coverage for CAM. Although 80% reported that they had received substantial benefit from their use of CAM, the majority (58%) did not discuss the use of these therapies with their medical doctor. CONCLUSIONS: Findings suggest that there is significant interest in and use of complementary/alternative medicine among elderly persons. These results suggest the importance of further research into the use and potential efficacy of these therapies within the senior population.

A review of mind/body therapies in the treatment of musculoskeletal disorders with implications for the elderly.

BACKGROUND: A comprehensive, but not systematic, review of the research on complementary and alternative treatments, specifically mind/body techniques, on musculoskeletal disease was conducted at Stanford University. The goals of the review were to establish a comprehensive literature review and provide a rationale for future research carrying the theme of "successful aging." METHODS: Computerized searches were conducted using MEDLINE, PsychInfo, Stanford Library, Dissertation Abstracts, Lexus-Nexus, the Internet as well as interviews conducted with practitioners and the elderly. Mind/body practices evaluated were: social support, cognitive-behavioral therapy, meditation, the placebo effect, imagery, visualization, spiritual/energy healing, music therapy, hypnosis, yoga, tai chi, and qigong. Studies published after 1990 were the priority, but when more recent literature was scarce, other controlled studies were included. RESULTS: Mind/body techniques were found to be efficacious primarily as complementary treatments for musculoskeletal disease and related disorders. Studies provided evidence for treatment efficacy but most apparent was the need for further controlled research. CONCLUSIONS: Reviewers found a dearth of randomized controlled research conducted in the US. There is a lack of studies with which to determine appropriate dosage and understand the mechanisms by which many of the practices work. Anecdotal evidence, some controlled research, clinical observation, as well as the cost effectiveness and lack of side effects of the mind/body treatments make further investigation a high priority.

Managing job strain: a randomized, controlled trial of an intervention conducted by mail and telephone.

A randomized, clinical intervention focused on alleviating job strain was conducted over 6 months by mail and/or telephone with a total of 136 employees of Bank of America. Both the mail and mail plus telephone interventions evidenced positive results, with the mail plus telephone intervention being the more effective. Given the relative low cost of such mediated interventions, the results provide a basis for the further development of interventions that may demonstrate both clinical and cost effectiveness.

A review of the incorporation of complementary and alternative medicine by mainstream physicians.

BACKGROUND: Studies suggest that between 30% and 50% of the adult population in industrialized nations use some form of complementary and/or alternative medicine (CAM) to prevent or treat a variety of health-related problems. METHOD: A comprehensive literature search identified 25 surveys conducted between 1982 and 1995 that examined the practices and beliefs of conventional physicians with regard to 5 of the more prominent CAM therapies: acupuncture, chiropractic, homeopathy, herbal medicine, and massage. Six studies were excluded owing to their methodological limitations. RESULTS: Across surveys, acupuncture had the highest rate of physician referral (43%) among the 5 CAM therapies, followed by chiropractic (40%) and massage (21%). Rates of CAM practice by conventional physicians varied from a low of 9% for homeopathy to a high of 19% for chiropractic and massage therapy. Approximately half of the surveyed physicians believed in the efficacy of acupuncture (51%), chiropractic (53%), and massage (48%), while fewer believed in the value of homeopathy (26%) and herbal approaches (13%). CONCLUSIONS: This review suggests that large numbers of physicians are either referring to or practicing some of the more prominent and well-known forms of CAM and that many physicians believe that these therapies are useful or efficacious. These data vary considerably across surveys, most likely because of regional differences and sampling methods, suggesting the need for more rigorous surveys using national, representative samples. Finally, outcomes studies are needed so that physicians can make decisions about the use of CAM based on scientific evidence of efficacy rather than on regional economics and cultural norms.

A review of mind-body therapies in the treatment of cardiovascular disease. Part 1: Implications for the elderly.

BACKGROUND: A review of research on complementary and alternative treatments, specifically mind-body techniques, was conducted at Stanford University. The goals of the review were to establish a comprehensive literature review and to provide a rationale for future research concerning successful aging. METHODS: Computerized searches were conducted using MEDLINE, PsychInfo, Stanford Library, Dissertation Abstracts, Lexus-Nexus, the Internet, and interviews conducted with practitioners. All studies since 1990 that examined mind-body treatments of cardiovascular disorders in the elderly were included. Mind-body practices evaluated were social support, cognitive-behavioral treatment, meditation, the placebo effect, hope, faith, imagery, spiritual healing, music therapy, hypnosis, yoga, t'ai chi, qigong and aikido. Studies conducted after 1990 were a priority, but when more recent literature was scarce, other studies using randomized, controlled trials were included. RESULTS: Mind-body techniques were found to be efficacious primarily as complementary and sometimes as stand-alone alternative treatments for cardiovascular disease-related conditions. Studies provided evidence for treatment efficacy, but the need for further controlled research was evident. CONCLUSIONS: Reviewers found only a handful of randomized, controlled research studies conducted in the United States. As a result, there is a lack of replicated studies with which to determine appropriate treatment dosage and the mechanisms by which many of the practices work. Compelling anecdotal evidence, the presence of some controlled research, overall cost effectiveness, and the lack of side effects resulting from mind-body treatments make further investigation a high priority.

Clinical and cost outcomes of multifactorial, cardiovascular risk management interventions in worksites: a comprehensive review and analysis.

This paper is a critical review of the clinical and cost outcome evaluation studies of multifactorial, comprehensive, cardiovascular risk management programs in worksites. A comprehensive international literature search conducted under the auspices of the National Heart, Lung and Blood Institute identified 17 articles based on 12 studies that examined the clinical outcomes of multifactorial, comprehensive programs. These articles were identified through MEDLINE, manual searches of recent journals, and through direct inquiries to worksite health promotion researchers. All studies were conducted between 1978 and 1995, with 1978 being the date of the first citation of a methodologically rigorous evaluation. Of the 12 research studies, only 8 utilized the worksite as both the unit of assignment and as the unit of analysis. None of the studies analyzed adequately for cost effectiveness. Given this limitation, this review briefly considers the relevant worksite research that has demonstrated cost outcomes. Worksite-based, multifactorial cardiovascular intervention programs reviewed for this article varied widely in the comprehensiveness, intensity, and duration of both the interventions and evaluations. Results from randomized trials suggest that providing opportunities for individualized, cardiovascular risk reduction counseling for high-risk employees within the context of comprehensive programming may be the critical component of an effective worksite intervention. Despite the many limitations of the current methodologies of the 12 studies, the majority of the research to date indicates the following: (1) favorable clinical and cost outcomes; (2) that more recent and more rigorously designed research tends to support rather than refute earlier and less rigorously designed studies; and (3) that rather than interpreting the methodological flaws and diversity as inherently negative, one may consider it as indicative of a robust phenomena evident in many types of worksites, with diverse employees, differing interventions, and varying degrees of methodological sophistication. Results of these studies reviewed provide both cautious optimism about the effectiveness of these worksite programs and insights regarding the essential components and characteristics of successful programs.

An intervention for enhancing compliance with screening recommendations for diabetic retinopathy. A bicoastal experience.

OBJECTIVE: To determine whether an intervention at both the provider and patient level can increase the utilization of diabetic retinal examination among diabetic patients and to compare the results from a comparable study conducted on the East Coast. RESEARCH DESIGN AND METHODS: For the regional intervention study, all diabetic patients 18 years or older who enrolled in a large network-based health maintenance organization (HMO) in California were identified (n = 19,397). The identified diabetic patients received educational materials and a notification of their prior diabetic retinal examination status. Also, their primary care physicians received the current American Diabetes Association (ADA) guidelines for dilated retinal examinations and a list of patients due for diabetic retinal examination. RESULTS: There were 25 and 27% increases in the percentage of diabetic patients who received diabetic retinal examinations in 1995 compared with the percentages in 1993 and 1994, respectively. The increase in diabetic retinal examinations was most significant after the intervention (odds ratio = 1.4). Furthermore, the improvements in compliance after the intervention were almost identical between the studies implemented on the East and West Coasts. CONCLUSIONS: This study and the prior study demonstrate that such a "reminder" intervention can improve compliance with diabetic retinal screening recommendations. A generalizable intervention, such as this, may be applicable on a national level. For these programs to be successful, however, HMOs and physicians must have a collaborative relationship.

The ecology of work and health: research and policy directions for the promotion of employee health.

This article identifies new research and policy directions for the field of worksite health in the context of the changing American workplace. These directions are viewed from an ecological perspective on worksite health and are organized around three major themes: (1) the joint influence of physical and social environmental factors on occupational health, (2) the effects of nonoccupational settings (e.g., households, the health care system) on employee well-being and the implications of recent changes in these settings for worksite health programs, and (3) methodological issues in the design and evaluation of worksite health programs. Developments in these areas suggest that the field of worksite health may be undergoing a fundamental paradigm shift away from individually oriented wellness programs (provided at the worksite and aimed primarily at changing employees' health behavior) and toward broader formulations emphasizing the joint impact of the physical and social environment at work, job-person fit, and work policies on employee well-being.

Evaluation of the IMPACT blood pressure program.

To evaluate the incremental effectiveness of a work-site blood pressure control program, we conducted a randomized, controlled trial at four work sites with established health promotion programs. Workers with blood pressures of 140/90 mm Hg or higher were eligible. Eighty subjects were assigned to receive a referral to a community physician, monthly 10-minute work-site counseling sessions including blood pressure readings, and personalized mailings, whereas 79 control subjects received only a physician referral. Results for 74 intervention and 71 control subjects were obtained after 1 year. As compared with control subjects, intervention subjects experienced average declines of 8.5/3.9 mm Hg. Adjusted for age, sex, and baseline blood pressure, the decreases were 7.6 mm Hg for systolic and 2.4 mm Hg for diastolic blood pressure. These results suggest that counseling of high-risk persons and personalized mailing programs can have an incremental benefit in controlling blood pressure.

Developing workplace health promotion programs through university and corporate collaboration. A review of the Corporate Health Promotion Research Program.

The unique collaboration of the UCSF School of Medicine with community and national leaders in corporate health promotion has, in less than three years, made the Corporate Health Promotion Research Program a valuable resource to participating corporations. We are able to offer them sound consultation on health promotion programs, based on state-of-the-art research, at minimal cost to the employer or employees. In addition, we are educating employers about quality programs and the process and need for evaluation, in an effort to generate sound findings on the effects of corporate health promotion programs. Corporations are beginning to see that instead of being reactive and spending great sums of money only after employees become ill, it makes good sense to institute programs designed to prevent employees from becoming ill in the first place. With such programs, corporations not only improve the health of their employees (a worthy objective in its own right), but they contribute to containing medical costs at the same time--a clear "win-win" situation for all concerned. In short, corporations are finding that an ongoing, active interest in the health of their employees has a direct bearing on their own long-range health as a business. With this in mind, we feel that medical benefit plans of the future will be comprised of three elements: medical care plus cost-containment plus health promotion programs. With this order of complexity, no one company or professional organization has all the answers--and that should be acknowledged from the outset.(ABSTRACT TRUNCATED AT 250 WORDS)
