A review and analysis of the clinical and cost-effectiveness studies of comprehensive health promotion and disease management programs at the worksite: 1995-1998 update (IV).

Purpose. This article is the fifth in a series of critical reviews of the clinical effectiveness and cost-effectiveness studies of comprehensive, multifactorial health promotion and disease management programs conducted in worksites. As with the previous reviews, the purpose of this article is to review and assess the randomized control trials that have focused on both clinical and cost outcomes of worksite health promotion and disease management programs. For this current review, a new category of quasi-experimental studies has been added because this represents a major new trend in such interventions over the last 2 years. Comprehensive worksite programs are those that provide an ongoing, integrated program of health promotion and disease prevention that integrates specific components into a coherent, ongoing program that is consistent with corporate objectives and includes program evaluations of both clinical and cost outcomes. Data Sources. A comprehensive search was conducted using a multistage process that included MEDLINE, ERIC, ADI, EDGAR, CARL, Inform, and Lexis-Nexis databases and direct inquiries to worksite researchers. Inclusion and Exclusion Criteria. The search identified 27 new studies to which the following inclusion criteria were applied: research conducted in the United States; results published in English; methodological quality of nonexperimental (pre- and postmeasures but no comparison group); quasi-experimental to randomized control trials; and both clinical and cost outcomes. Exclusion criteria were studies outside of the United States; non-English publications; and clinical or cost outcomes only. Fifteen studies remained for this review. Findings Extraction Methods. Findings extraction and analysis of the 15 studies was done by extracting the relevant population, intervention design, clinical results, and cost outcomes from the published article. As in previous reviews, findings are summarized in a table format that extracts and describes each study by the following: (1) study author(s); (2) corporate site; (3) purpose of the evaluation; (4) employee population; (5) percentage of program participants; (6) number of employees included in the evaluation; (7) brief description of the intervention; (8) evaluation design; (9) evaluation period; (10) outcomes; (11) research rating; and (12) findings. Findings Synthesis. Based on these 15 studies, a methodological critique was conducted with brief reference to appropriate prior studies. Conclusions regarding study quality and new trends over the time period of 1998 to 2000 are discussed. Major Conclusions. Results from randomized clinical trials and quasi-experimental designs suggest that providing individualized risk reduction for high risk employees within the context of comprehensive programming is the critical element of worksite interventions. Despite the many limitations of the current methodologies of the 15 new studies, the vast majority of the research to date indicates positive clinical and cost outcomes.

Stanford presenteeism scale: health status and employee productivity.

Workforce productivity has become a critical factor in the strength and sustainability of a company’s overall business performance. Absenteeism affects productivity; however, even when employees are physically present at their jobs, they may experience decreased productivity and below-normal work quality—a concept known as decreased presenteeism. This article describes the creation and testing of a presenteeism scale evaluating the impact of health problems on individual performance and productivity. A total of 175 county health employees completed the 34-item Stanford Presenteeism Scale (SPS-34). Using these results, we identified six key items to describe presenteeism, resulting in the SPS-6. The SPS-6 has excellent psychometric characteristics, supporting the feasibility of its use in measuring health and productivity. Further validation of the SPS-6 on actual presenteeism (work loss data) or health status (health risk assessment or utilization data) is needed.

A review and analysis of the health and cost-effective outcome studies of comprehensive health promotion and disease prevention programs at the Worksite: 1991-1993 update

Editor Note: This is the second in a series of articles authored by Dr. Kenneth R. Pelletier summarizing the results of studies examining the impact of comprehensive health promotion programs on health and cost. We received over 6,500 reprint requests for the first article, far more than we have received for any other article we have published. Dr. Pelletier updated the summary due to the tremendous response it received and due to the fact that 23 additional studies have been published since the first summary was printed. Our intention is to continue publishing updated summaries of the impact of comprehensive health promotion programs on health and financial outcome measures periodically, and to include all studies published in rigorous peerreviewed journals. If we have missed a study, please send us a copy to include in the next update.

A review and analysis of the clinical and cost-effectiveness studies of comprehensive health promotion and disease management programs at the worksite: Update VII 2004-2008

Objective: To conduct the seventh periodic review and analysis of the clinical and cost-effectiveness research conducted in worksite/corporate environments between 2004 and 2008. Methods: A literature search of US-based research was conducted using a multistage process including MEDLINE, ADI, EDGAR, CARL, Inform, Lexis-Nexis, as well as direct inquiries to key researchers in this area of expertise. Results: From 2004 to 2008, there were 16 new studies that met the Inclusion/Exclusion criteria. These studies are critiqued and entered into a data table consisting of 13 variables and citations of the 16 new studies. Conclusions: Clinical and cost-effectiveness research in the worksite/corporate environment continues to evolve although there was only one randomized clinical trial conducted during the most recent interval. There are innovations in pilot studies, quasi-experimental methodologies, and econometric modeling as indicative of future trends.

Current Trends in the Integration and Reimbursement of Complementary and Alternative Medicine by Managed Care, Insurance Carriers, and Hospital Providers

Objectives. To assess the status of managed care and insurance coverage of complementary and alternative medicine (CAM) and the integration of such services offered by hospitals. Methods. A literature review and information search was conducted to determine which insurers had special policies for CAM and which hospitals were offering CAM. Telephone interviews were conducted with a definitive sample of 18 insurers and a representative subsample of seven hospitals. Results. A majority of the insurers interviewed offered some coverage for the following: nutrition counseling, biofeedback, psychotherapy, acupuncture, preventive medicine, chiropractic, osteopathy, and physical therapy. Twelve insurers said that market demand was their primary motivation for covering CAM. Factors determining whether insurers would offer coverage for additional therapies included potential cost-effectiveness based on consumer interest, demonstrable clinical efficacy, and state mandates. Some hospitals are also responding to consumer interest in CAM, although hospitals can only offer CAM therapies for which local, licensed practitioners are available. Among the most common obstacles listed to incorporating CAM into mainstream health care were lack of research on efficacy, economics, ignorance about CAM, provider competition and division, and lack of standards of practice. Conclusions. Consumer demand for CAM is motivating more insurers and hospitals to assess the benefits of incorporating CAM. Outcomes studies for both allopathic and CAM therapies are needed to help create a health care system based upon treatments that work, whether they are mainstream, complementary, or alternative.

Mindfulness goes to work: impact of an online workplace intervention.

Objective: The objective of this study was to determine whether a mindfulness program, created for the workplace, was both practical and efficacious in decreasing employee stress while enhancing resiliency and well-being. Methods: Participants (89) recruited from The Dow Chemical Company were selected and randomly assigned to an online mindfulness intervention (n = 44) or wait-list control (n = 45). Participants completed the Perceived Stress Scale, the Five Facets of Mindfulness Questionnaire, the Connor-Davidson Resiliency Scale, and the Shirom Vigor Scale at pre- and postintervention and 6-month follow-up. Results: The results indicated that the mindfulness intervention group had significant decreases in perceived stress as well as increased mindfulness, resiliency, and vigor. Conclusions: This online mindfulness intervention seems to be both practical and effective in decreasing employee stress, while improving resiliency, vigor, and work engagement, thereby enhancing overall employee well-being.

Current trends in the integration and reimbursement of complementary and alternative medicine by managed care organizations (MCOs) and insurance providers: 1998 Update and cohort analysis

Objectives. To assess the status of managed care and insurance coverage of complementary and alternative medicine (CAM) and the integration of such services into conventional medicine. Methods. A literature review and information search was conducted to determine which insurers had special policies for CAM. Telephone interviews were conducted with a definitive sample of 9 out of 10 new MCOs or insurers identified in 1998 and a cohort of eight MCOs and insurers who responded both to the original survey in 1997 and again in 1998 to determine trends. Results. This study constitutes the results of the second year of a 3-year ongoing survey. For 1998, 10 MCOs and insurance carriers initiated CAM coverage. Survey results are analyzed for these 10 new providers as well as the results of a cohort of eight insurers surveyed in both 1997 and 1998 to determine current trends. A majority of the insurers interviewed offer some coverage for the following: nutrition counseling, biofeedback, psychotherapy, acupuncture, preventive medicine, chiropractic, osteopathy, and physical therapy. All new MCOs and insurers said that market demand was their primary motivation for covering CAM. Factors determining whether insurers would offer coverage for additional therapies included potential cost-effectiveness, consumer interest, demonstrable clinical efficacy, and state mandates. Among the most common obstacles listed to incorporating CAM into mainstream health care were lack of research on efficacy, economics, ignorance about CAM, provider competition and division, and lack of standards of practice. Conclusions. Consumer demand for CAM is motivating more MCOs and insurance companies to assess the benefits of incorporating CAM. Outcomes studies for both conventional and CAM therapies are needed to help create a health care system based upon treatments that work, whether they are conventional, complementary, or alternative.

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.

Healthy people--healthy business: a critical review of stress management programs in the workplace.

Although stress management programs continue to be cited by both employers and employees as the number one program priority, many programs in place do not seem to be cost effective or health effective. Some common characteristics of the most efficacious programs can be identified, and some potentially different approaches should be considered.

Using a return-on-investment estimation model to evaluate outcomes from an obesity management worksite health promotion program

Objective: Certain modifiable risk factors lead to higher health care costs and reduced worker productivity. A predictive return-on-investment (ROI) model was applied to an obesity management intervention to demonstrate the use of econometric modeling in establishing financial justification for worksite health promotion. Methods: Self-reported risk factors (n = 890) were analyzed using &khgr;2 and t test methods. Changes in risk factors, demographics, and financial measures comprised the model inputs that determined medical and productivity savings. Results: Over 1 year, 7 of 10 health risks decreased. Of total projected savings (
