Cardiovascular disease prevention and implications for worksite health promotion programs in Brazil.

Economic growth, an aging population, and changes in lifestyle patterns have contributed to the rise in cardiovascular disease (CVD) in Brazil. Worksite health and wellness programs are viewed as a potentially viable means to address the increase in disease burden in Brazil. The purpose of the present review is to investigate actions proposed by the Brazilian Government for CVD prevention and the current state of worksite health promotion. Our review of literature found that the Brazilian Government has been showing a growing interest in developing and promoting CVD preventive strategies, primarily through better control of known risk factors (i.e. smoking, obesity, physical inactivity, high cholesterol, high blood pressure, and high blood glucose). Current initiatives are considered positive steps toward better CVD prevention in Brazil. With respect to worksite health and wellness, additional work is needed to determine optimal program delivery models, financial implications and individual/population compliance with healthier lifestyle choices.

A naturopathic approach to the prevention of cardiovascular disease: cost-effectiveness analysis of a pragmatic multi-worksite randomized clinical trial.

OBJECTIVE: To determine the cost-effectiveness of a worksite-based naturopathic (individualized lifestyle counseling and nutritional medicine) approach to primary prevention of cardiovascular disease (CVD). METHODS: Economic evaluation alongside a pragmatic, multi-worksite, randomized controlled trial comparing enhanced usual care (EUC; usual care plus biometric screening) to the addition of a naturopathic approach to CVD prevention (NC+EUC). RESULTS: After 1 year, NC+EUC resulted in a net decrease of 3.3 (confidence interval: 1.7 to 4.8) percentage points in 10-year CVD event risk (number needed to treat = 30). These risk reductions came with average net study-year savings of $1138 in societal costs and $1187 in employer costs. There was no change in quality-adjusted life years across the study year. CONCLUSIONS: A naturopathic approach to CVD primary prevention significantly reduced CVD risk over usual care plus biometric screening and reduced costs to society and employers in this multi-worksite-based study. Trial Registration clinicaltrials.gov Identifier: NCT00718796.

Value of chiropractic services at an on-site health center.

OBJECTIVE: Chiropractic care offered at an on-site health center could reduce the economic and clinical burden of musculoskeletal conditions. METHODS: A retrospective claims analysis and clinical evaluation were performed to assess the influence of on-site chiropractic services on health care utilization and outcomes. RESULTS: Patients treated off-site were significantly more likely to have physical therapy (P < 0.0001) and outpatient visits (P < 0.0001). In addition, the average total number of health care visits, radiology procedures, and musculoskeletal medication use per patient with each event were significantly higher for the off-site group (all P < 0.0001). Last, headache, neck pain, and low back pain-functional status improved significantly (all P < 0.0001). CONCLUSIONS: These results suggest that chiropractic services offered at on-site health centers may promote lower utilization of certain health care services, while improving musculoskeletal function.

Effectiveness of a multidisciplinary care program on recovery and return to work of patients after gynaecological surgery; design of a randomized controlled trial.

BACKGROUND: Return to work after gynaecological surgery takes much longer than expected, irrespective of the level of invasiveness. In order to empower patients in recovery and return to work, a multidisciplinary care program consisting of an e-health intervention and integrated care management including participatory workplace intervention was developed. METHODS/DESIGN: We designed a randomized controlled trial to assess the effect of the multidisciplinary care program on full sustainable return to work in patients after gynaecological surgery, compared to usual clinical care. Two hundred twelve women (18-65 years old) undergoing hysterectomy and/or laparoscopic adnexal surgery on benign indication in one of the 7 participating (university) hospitals in the Netherlands are expected to take part in this study at baseline. The primary outcome measure is sick leave duration until full sustainable return to work and is measured by a monthly calendar of sickness absence during 26 weeks after surgery. Secondary outcome measures are the effect of the care program on general recovery, quality of life, pain intensity and complications, and are assessed using questionnaires at baseline, 2, 6, 12 and 26 weeks after surgery. DISCUSSION: The discrepancy between expected physical recovery and actual return to work after gynaecological surgery contributes to the relevance of this study. There is strong evidence that long periods of sick leave can result in work disability, poorer general health and increased risk of mental health problems. We expect that this multidisciplinary care program will improve peri-operative care, contribute to a faster return to work of patients after gynaecological surgery and, as a consequence, will reduce societal costs considerably.

[Improvement of the organization of oncological aid under conditions of specific technogenic load on the population].

Social and economic disbenifits due to mortality from malignant neoplasms were estimated taking into account the losses of man-years of work, mean life expectancy for the sick, losses from temporary disablement and invalidization caused by malignancies, and the cost of oncological aid. The study was based at an area in Uzbekistan subjected to pollution by industrial wastes from an uranium-extracting enterprise. A special purpose-oriented program has been elaborated for the correction of oncological aid currently provided to the workers of the Navoi mining and metallurgical works and the local population. Its implementation resulted in a 13% reduction of standardized mortality from malignant neoplasm in 2004 compared with 1999 and another 24% in 2009. The disbenefit prevented by the reduction of mortality at active ages is estimated at 60,6 mln rubles.

Health and medical economics applied to integrative medicine.

Cost-benefit analyses (CBA) of every aspect of health and medical care are a necessity to address both the clinical effectiveness and cost effectiveness of health and medical care for the purpose of allocating limited practitioner, organizational, governmental, and monetary resources while maintaining the highest quality outcomes. In response, there are an array of approaches that emphasize the full continuum of prevention, restructuring primary care, involvement of the workplace and communities, and adoption of innovative strategies and interventions ranging from genomic assessments to complementary and alternative medicine (CAM). Among these approaches is an integrative medicine (IM) model that is consistent with these national objectives and that uniquely and explicitly includes "evidence-based global medical strategies" in its definition. All of these strategies require rigorous, appropriate, state-of-the art medical economic analyses. Since few if any IM models have been rigorously evaluated in terms of CBA, it is possible to draw upon the cost-effectiveness research focused on a limited number of CAM modalities as well as from the work-site/corporate clinical and cost outcomes research to suggest the evidence-based foundation from which a true healthcare system will evolve.

Cost-effectiveness of a participatory return-to-work intervention for temporary agency workers and unemployed workers sick-listed due to musculoskeletal disorders: design of a randomised controlled trial.

BACKGROUND: Within the working population there is a vulnerable group: workers without an employment contract and workers with a flexible labour market arrangement, e.g. temporary agency workers. In most cases, when sick-listed, these workers have no workplace/employer to return to. Also, for these workers access to occupational health care is limited or even absent in many countries. For this vulnerable working population there is a need for tailor-made occupational health care, including the presence of an actual return-to-work perspective. Therefore, a participatory return-to-work program has been developed based on a successful return-to-work intervention for workers, sick-listed due to low back pain.The objective of this paper is to describe the design of a randomised controlled trial to study the (cost-)effectiveness of this newly developed participatory return-to-work program adapted for temporary agency workers and unemployed workers, sick-listed due to musculoskeletal disorders, compared to usual care. METHODS/DESIGN: The design of this study is a randomised controlled trial with one year of follow-up. The study population consists of temporary agency workers and unemployed workers sick-listed between 2 and 8 weeks due to musculoskeletal disorders. The new return-to-work program is a stepwise program aimed at making a consensus-based return-to-work implementation plan with the possibility of a (therapeutic) workplace to return-to-work. Outcomes are measured at baseline, 3, 6, 9 and 12 months. The primary outcome measure is duration of the sickness benefit period after the first day of reporting sick. Secondary outcome measures are: time until first return-to-work, total number of days of sickness benefit during follow-up; functional status; intensity of musculoskeletal pain; pain coping; and attitude, social influence and self-efficacy determinants. Cost-benefit is evaluated from an insurer's perspective. A process evaluation is part of this study. DISCUSSION: For sick-listed workers without an employment contract there can be gained a lot by improving occupational health care, including return-to-work guidance, and by minimising the 'labour market handicap' by creating a return-to-work perspective. In addition, reduction of sickness absence and work disability, i.e. a reduction of disability claims, may result in substantial benefits for the Dutch Social Security System.

The impact of the highmark employee wellness programs on 4-year healthcare costs.

OBJECTIVE: To determine the return on investment (ROI) of Highmark Inc.'s employee wellness programs. METHODS: Growth curve analyses compared medical claims for participants of wellness programs versus risk-matched nonparticipants for years 2001 to 2005. The difference was used to define savings. ROI was determined by subtracting program costs from savings and alternative discount rates were applied in a sensitivity analysis. RESULTS: Multivariate models estimated health care expenses per person per year as $176 lower for participants. Inpatient expenses were lower by $182. Four-year savings of $1,335,524 compared with program expenses of $808,403 yielded an ROI of $1.65 for every dollar spent on the program. CONCLUSIONS: Using sophisticated methodology, this study suggests that a comprehensive health promotion program can lower the rate of health care cost increases and produce a positive ROI.

Improving depression treatment by integrated care.

OBJECTIVE: To identify the clinical and economic implications of depression in the workplace and review how integrated care models can improve overall patient outcomes. SUMMARY: Depression is a significant financial burden to the employer due to lost days of work and decreased productivity. Employers are demanding return on the investment for their increasing health care expenditures. The cost of depression to employers may be contained by delivering care using integrated models that leverage primary care provider treatment with care management and mental health consultation. CONCLUSION: There is a need to reduce silos in the organization and financing of mental health care to prevent cost shifting that provides no benefit to patients, payers or providers. Poor mental health care will likely lead to a rise in absenteeism and presenteeism.

Promoting health and productivity for depressed patients in the workplace.

OBJECTIVE: To discuss the impact of major disease states, including depression, in the loss of productivity in the workplace and how integration of health care can decrease cost to employers. SUMMARY: The majority of costs associated with depressive illness can be traced to lost productivity, and the employer, therefore, bears most of the economic burden. Efforts to improve employee health and productivity have been hampered by the compartmentalization of medical costs, pharmacy costs, behavioral health costs, and productivity measures. This situation can be rectified by "busting" these silos and promoting a reintegration of prospective costs and parties. Health risk assessments enable employers to identify illnesses that are suitable targets for integrated health and productivity management programs. In the case of depression, employers can act proactively to identify employees at risk, working to minimize risk factors such as stress before these individuals become heavy utilizers of company resources. For employees who are currently depressed, recent research evidence has demonstrated that pharmacotherapy can have a dramatic and positive effect on lost productivity, absenteeism, and presenteeism. The selection of antidepressants and subsequent follow-up must be improved, however, if the benefits of pharmacotherapy are to be optimized. CONCLUSION: Understanding the linkage of disease management and productivity in the workplace can result in dramatic decreases in absenteeism and presenteeism and increased cost savings to the employers.

Back schools in occupational health care: design of a randomized controlled trial and cost-effectiveness study.

OBJECTIVE: To describe the design of a randomized controlled trial (RCT), including a cost-effectiveness analysis, comparing high-intensity and low-intensity back schools with usual care in occupational health care. DESIGN: RCT and cost-effectiveness analysis. STUDY POPULATION: Employees sick-listed for a period of 3 to 6 weeks because of nonspecific low back pain. Interventions High-intensity back school treatment consists of a training program based on the principles of cognitive-behavioral therapy. Low-intensity back school treatment is comparable to the original Swedish Back School. Usual care is provided by the occupational physician according to the Dutch guidelines for the occupational health treatment of patients with low back pain. OUTCOME MEASURES: Primary outcome measures are return to work, pain intensity, functional status, and general improvement. Secondary outcome measures are kinesiophobia and pain coping. The cost-effectiveness analysis includes the direct and indirect costs. The outcome measures are assessed before randomization and 3, 6, and 12 months after randomization. CONCLUSION: RCTs of different methodological quality have been conducted to examine the effectiveness of back schools in occupational health care. The large variation in type, content, and intensity of back schools has led to conflicting evidence. Therefore, 2 different forms of back schools are compared. Moreover, this is the first RCT to include a cost-effectiveness analysis comparing low-intensity and high-intensity back schools with usual care in occupational health care.

Physician assistants in occupational medicine: how do they compare to occupational physicians?

BACKGROUND: Physician assistants (PAs) have been present in occupational and environmental medicine (OEM) in the USA since 1971, yet remarkably little is known about their activity. METHODS: An administrative study of PA activities was undertaken and compared with the activities of physicians in the same occupational medicine setting. Patients were not triaged to either provider and all resources of care were recorded for the visit. An episode of care approach was used for the analysis. RESULTS: The characteristics of patients seen by each provider were similar in age, gender ratio and severity of injury. Physicians saw a mean of 2.9 patients/h and PAs 2.5, but PAs worked more hours and saw more patients per year than physicians. The average charge per patient visit and total charge for an episode of care were similar. Differences between PAs and physicians were seen in the areas of 'limited duty' duration given to patients and on average PAs prescribed 15 days and physicians 17 days. PAs referred a patient 19.7% of the time, while physicians referred 17.4%. Most of the referrals were to physical therapy. The salary of a physician, based on an hourly rate, was approximately twice as much as a PA. CONCLUSION: The use of PAs in OEM may represent a cost-effective advantage from an administrative standpoint. Clearly, more research is necessary in determining the role and utilization of PAs in OEM and how they may improve the delivery of physician services.

[Cost analysis of task implementation at the regional occupational medicine centers]. / Analiza kosztów realizacji wybranych zadan wojewódzkich osrodków medycyny pracy.

In this paper, the considerations on setting the costs of the tasks to be implemented by provincial occupational medicine centers (POMCs) are continued (Med Pr 2001; 3: 197-201). Under the research project carried out by the Nofer Institute of Occupational Medicine, the method of setting costs has been elaborated and implemented in selected POMCs. At the implementation stage, a set of forms to collect and process data on costs involved was prepared. These forms together with the instruction were distributed among the selected centers. The data collected were analyzed, and the conclusions concerning the factors responsible for shaping relevant costs in POMCs, as well as the barriers hindering the implementation of this new method were formulated. The introduction of new principles of isolating so called "cost phases" was necessary only for setting full costs of health promotion and postgraduate education programs. The method of setting values for the remaining POMC costs has been implemented without its modification. The collected data on costs show that the wages of physicians and medium-level personnel affects mostly the costs of tasks in a given center, however, indirect costs also have a substantial share in unit costs. In addition, the range of specialistic consultations and diagnostic tests performed in or outside POMCs also exert some effect on the differentiation of unit costs.

[Financing of regional occupational health service centers: structure and financial criteria in years 2000-2001]. / Poziom, struktura i kryteria finansowania wojewódzkich osrodków medycyny pracy w latach 2000-2001.

The rational planning and financing of occupational health services at the national level have to be based on an appropriate system of information about individual units and their financial status that could illustrate their financial administration. This is required not only in view of the internal needs of public money management, but also in view of the national health accounts. The major task in this regard is to assess the level and structure of financing to individual units and to check the soundness of criteria used in the process of supplying financial means. The results of such an analysis can be a valuable source of information for planning carried out also by the institutions which provide funds to cover the cost of tasks performed by individual units. The aim of the project implemented by the Nofer Institute of Occupational Medicine was to collect, process and analyze data on the level and structure of financing of provincial occupational medicine centers. In this paper, the objectives, methodology and analytical tools are discussed. The results and structural data on the level and structure of financing of regional occupational health services centers covering a two-year period are presented. At the same time, the criteria for allocating funds were identified, which made it possible to evaluate the situation and to propose new solutions.

The effectiveness of standard care, early intervention, and occupational management in worker's compensation claims.

STUDY DESIGN: A retrospective and prospective cohort. OBJECTIVES: To compare the effectiveness of occupational intervention, early intervention, and standard care in the management of Worker's Compensation injury claims. SUMMARY OF BACKGROUND DATA: The current management of occupational back pain and work-related upper extremity disorders with either standard care or early intervention appears to be ineffective. METHODS: A retrospective cohort compared injury claim incidence, duration, and costs between one company with access to standard care and another similar company with access to early intervention. A prospective cohort looked at the effect of one company changing from standard care to occupational management in comparison with the control group with early intervention. Survival analysis was used to attempt to explain differences in injury claim duration. RESULTS: Standard care resulted in lower injury claim incidence, duration, and costs than early intervention, whereas occupational management resulted in lower injury claim incidence, duration, and costs than standard care. The covariates of physical therapist involvement, chiropractor involvement, injury severity, and relationship between Worker's Compensation and the employer were associated with delayed time to claim closure in the company with access to early intervention with the most important covariate being physical therapist involvement (hazard rate ratio 19.88, 95% confidence interval 7.95-39.77). Only the covariate of injury severity was associated with delayed time to claim closure in the company with access to occupational management (hazard rate ratio 1.67, 95% confidence interval 1.05-27.20). CONCLUSIONS: It is recommended that an occupational management approach, in comparison with standard care or early intervention, be considered for management of occupational injuries.

Pharmaceuticals--cost or investment? An employer's perspective.

Employers are becoming increasingly concerned about rising pharmaceutical costs. Are improved health and cost outcomes achieved as a result of increasing pharmaceutical costs? One should approach this issue with a holistic view that considers the overall impact that disease conditions have on health and productivity. To illustrate, we first identified the "top ten" most expensive physical and mental health concerns facing American businesses, using data from over 60 firms from the 1996 MarketScan Private Pay Fee-For-Service Research Database. For some of these top ten conditions, the literature already addresses the drug cost versus investment issue, with mixed results. For conditions in which uncertainty prevails and for other high-cost conditions, empirical analyses should address the drug cost versus investment issue to minimize the risk of a penny-wise and pound-foolish payment/coverage policy. A similar strategy should be applied to individual corporate diagnostic assessments.

Projecting future medical care costs using four scenarios of lifestyle risk rates.

PURPOSE: This study predicts medical care expenditures over 10 years for Union Pacific Railroad (UPRR) under alternative health risk factor scenarios for the UPRR workforce. DESIGN: This paper describes the development of an economic forecasting model to predict medical care expenditures assuming four different scenarios of population risk. The variables used to predict medical care expenditures are employee demographics and health risk profiles. SETTING: UPRR is a transportation company with more than 56,000 employees in 25 states west and south of the Mississippi River. SUBJECTS: Employees of UPRR. MEASURES: Intermediate outcomes included health risk measures related to exercise patterns, body weight, eating habits, smoking, alcohol consumption, total cholesterol, blood glucose, blood pressure, stress, and depression. Major outcome measures included projected total annual payments by UPRR for medical care services for the decade following 1998. RESULTS: The UPRR work force is projected to grow by 500 employees per year over the 10-year study period. The average age is expected to increase from 44 to 48 years. Without further health promotion intervention, 7 of the 11 risk factors assessed would likely worsen among UPRR's workforce. Medical care cost increases are projected to range from $22.2 million to $99.6 million in constant 1998 dollars over the next decade, depending on the effectiveness of risk factor modification programs. With an expected health promotion budget averaging $1.9 million annually over 10 years, health risks must decline at least 0.09% per year for the program to pay for itself. CONCLUSIONS: Estimating various risk and cost scenarios can facilitate program planning and produce an economic justification for worksite health programs.

Offshore energy boom providing opportunities outside Medicare's umbrella.

Physicians upset by limits imposed by the medicare system are getting a chance to spread their entrepreneurial wings on the East Coast. A boom in offshore exploration, led by Newfoundland's massive Hibernia project, has led to numerous business opportunities for physicians.

How I help managers understand and value an occupational health department.

A professional occupational health department is more valuable to businesses than an old-style medical department. Occupational health professionals need to rise to the challenge of promoting the contribution they can make. This article discusses some of the key points which need to be addressed when helping managers understand occupational health's important role.
