Improving the quality of workers' compensation health care delivery: the Washington State Occupational Health Services Project.

This article has summarized research and policy activities undertaken in Washington State over the past several years to identify the key problems that result in poor quality and excessive disability among injured workers, and the types of system and delivery changes that could best address these problems in order to improve the quality of occupational health care provided through the workers' compensation system. Our investigations have consistently pointed to the lack of coordination and integration of occupational health services as having major adverse effects on quality and health outcomes for workers' compensation. The Managed Care Pilot Project, a delivery system intervention, focused on making changes in how care is organized and delivered to injured workers. That project demonstrated robust improvements in disability reduction; however, worker satisfaction suffered. Our current quality improvement initiative, developed through the Occupational Health Services Project, synthesizes what was learned from the MCP and other pilot studies to make delivery system improvements. This initiative seeks to develop provider incentives and clinical management processes that will improve outcomes and reduce the burden of disability on injured workers. Fundamental to this approach are simultaneously preserving workers' right to choose their own physician and maintaining flexibility in the provision of individualized care based on clinical need and progress. The OHS project then will be a "real world" test to determine if aligning provider incentives and giving physicians the tools they need to optimize occupational health delivery can demonstrate sustainable reduction in disability and improvements in patient and employer satisfaction. Critical to the success of this initiative will be our ability to: (1) enhance the occupational health care management skills and expertise of physicians who treat injured workers by establishing community-based Centers of Occupational Health and Education; (2) design feasible methods of monitoring patient outcomes and satisfaction with the centers and with the providers working with them in order to assess their effectiveness and value; (3) establish incentives for improved outcomes and worker and employer satisfaction through formal agreements with the centers and providers; and (4) develop quality indicators for the three targeted conditions (low back sprain, carpal tunnel syndrome, and fractures) that serve as the basis for both quality improvement processes and performance-based contracting. What lessons or insights does our experience offer thus far? The primary lesson is the importance of making effective partnerships and collaborations. Our policy and research activities have benefited significantly from the positive relationship the DLI established with the practice community through the Washington State Medical and Chiropractic Associations and from the DLI's close association with the Healthcare Subcommittee of the Workers' Compensation Advisory Committee. This committee is established by state regulation and serves as a forum for dialogue between the committee and the employer and labor communities. Our experience thus underscores the importance of establishing broad-based support for delivery system innovations. Our research activities have also benefited from the close collaboration between DLI program staff and UW health services researchers. The DLI staff brought important program and policy experience, along with an appreciation of the context and environment within which the research, policy, and R&D activities were conducted. The UW research team brought scientific rigor and methodological expertise to the design and implementation of the research and policy activities. In Washington State, the DLI represents a "single payer" for the purposes of workers' compensation. As discussed earlier, Washington State, along with five other states, has a state-fund system that requires all employers that are not self-insured to purchase workers' compensation insurance through the state fund. No matter what one feels about the merits or drawbacks of a single-payer system of health care financing, the fact is that such a system creates important opportunities for policy initiatives and for research and evaluation. Our ability to access population-based data on injured workers and to develop policy initiatives through innovation and pilot testing to assess whether proposed changes are really improvements has been critical. Understanding what works within the constraints and complexities of the system on a small scale is critical in order to bring forth policy and processes that will be of value systemwide. Finally, we note that general medical care faces many of the same quality-related problems and challenges as occupational health care. Medical care for chronic diseases, such as diabetes, is often fragmented and uncoordinated. (ABSTRACT TRUNCATED)

Application of incremental change strategies in chiropractic and multidisciplinary clinical settings for quality improvement.

Care for low back pain remains a clinical enigma. Its high prevalence and cost to the system warrants attention for improvement. Although, no major recent clinical breakthroughs for resolving back pain have emerged, reducing unnecessary tests, eliminating useless or harmful practices, preventing care dependence, and enhancing coping skills can be useful goals for improving patient outcomes. Quality Improvement (QI) approaches can serve as bridge between clinical intuition and large scale science. Three chiropractic delivery settings including two teaching clinics and one large multidisciplinary spine care center incorporated QI approaches as part of an initiative to improve low back pain care. All clinics were able to implement sustainable process and outcomes improvements.

Comparison of work and time estimates by chiropractic physicians with those of medical and osteopathic providers.

BACKGROUND: Resource-based relative value scales (RBRVS) have become a standard method for identifying costs and determining reimbursement for physician services. Development of RBRVS systems and methods are reviewed, and the RBRVS concept of physician "work" is defined. OBJECTIVE: Results of work and time inputs from chiropractic physicians are compared with those reported by osteopathic and medical specialties. Last, implications for reimbursement of chiropractic fee services are discussed. METHODS: Total work, intraservice work, and time inputs for clinical vignettes reported by chiropractic, osteopathic, and medical physicians are compared. Data for chiropractic work and time reports were drawn from a national random sample of chiropractors conducted as part of a 1997 workers' compensation chiropractic fee schedule development project. Medical and osteopathic inputs were drawn from RBRVS research conducted at Harvard University under a federal contract reported in 1990. Both data sets used the same or similar clinical vignettes and similar methods. Comparisons of work and time inputs are made for clinical vignettes to assess whether work reported by chiropractors is of similar magnitude and variability as work reported by other specialties. RESULTS: Chiropractic inputs for vignettes related to evaluation and management services are similar to those reported by medical specialists and osteopathic physicians. The range of variation between chiropractic work input and other specialties is of similar magnitude to that within other specialties. Chiropractors report greater work input for radiologic interpretation and lower work input for manipulation services. CONCLUSIONS: Chiropractors seem to perform similar total "work" for evaluation and management services as other specialties. No basis exists for excluding chiropractors from using evaluation and management codes for reimbursement purposes on grounds of dissimilar physician time or work estimates. Greater work input by chiropractors in radiology interpretation may be related to a greater importance placed on findings in care planning. Consistently higher reports for osteopathic work input on manipulation are likely attributable to differences in reference vignettes used in the respective populations. Research with a common reference vignette used for manipulation providers is recommended, as is development of a single generic approach to coding for manipulation services.

Establishment of total and intraservice work by chiropractic physicians in providing spinal manipulative therapy and evaluation and management services.

OBJECTIVE: To develop and test a self-report survey instrument that measures the work performed by chiropractors in the delivery of evaluation and management (E/M) services and spinal manipulative therapy (SMT). Work is one leg of a triad used to develop Resource-Based Relative Values Scales (RBRVS) for physician reimbursement. DESIGN: Reliability study modeled after a tool designed and tested by economists at Harvard University School of Public Health in the development of relative values scales for physician reimbursement. The survey instrument uses magnitude estimation as a means of obtaining reliable and valid measures of the subjective assessments of the dimensions of a physicians work. SAMPLE: A random national sample was drawn from all members of the American Chiropractic Association. RESULTS: Estimates of the work performed by chiropractors in providing E/M and SMT services were established. The reliability of work ratings indicated that chiropractors agree closely on their ratings for work. The validity of the results indicated a high degree of consistency in rating work, which implies that the results are realistic. A review of demographics suggested that the survey population was representative of the general population of chiropractors. CONCLUSIONS: This study generated valid and reliable estimates of the work performed by chiropractors in providing E/M and SMT services. Work is one of three components used in the development of RBRVS, the method of physician reimbursement that is currently the industry standard. By quantifying the work required in providing services, chiropractors can now develop RBRVS. Additionally, the evidence-based data on work collected here can be used for a comparison with the work of similar services provided by other specialists. This can facilitate the use or modification of service description codes for use by chiropractic physicians.

The impact of health policy on chiropractic.

OBJECTIVE: The chiropractic profession has traditionally had little or no direct influence on health policy. Conversely, every chiropractor is impacted daily by health policy decisions promulgated by government agencies, health purchasers, managed care organizations and others. This discussion provides an overview of health policy constituencies important to chiropractors, reviews processes currently being used to assess health care technology and develop policy and offers strategies for the profession to more actively engage in constructive policy development. METHOD: Descriptive overview of key issues based on qualitative selective overview of literature and author's observations based on two years employment in a government health policy position. CONCLUSIONS: The chiropractic profession's traditional approach to influencing health policy has focused on public relations, political lobbying for favorable legislation and litigation, which has increased public awareness and resulted in a number of legislative successes. However, for the most part, the momentum of decision-making at agency levels and in policy staff positions continues to occur without involvement of chiropractors trained or experienced in policy-making. This is in contrast with medicine and other allied health fields, whose ranks hold such positions routinely. Additionally, methodology for policy decision-making is increasingly evidence-based. Strategies for the chiropractic profession to more actively participate in this arena are offered.

Resource-Based Relative Value Scales: impacts and recommendations relative to chiropractic practice.

PURPOSE: The American health care financing and delivery system is changing at a rapid pace. As part of recent reform of payment systems for physician services, Medicare has adopted a resource-based relative value scale (RBRVS) that is becoming a national standard. Research has now documented characteristics of physicians' work and the overhead for providing specific health services for most medical specialties and disciplines. This information is being used to develop service descriptions (billing codes) and reimbursement levels. No such data exist relative to chiropractic, which may hinder chiropractic's efforts to be included in evolving reimbursement schemes. RBRVS and its relevance to chiropractic is reviewed, information on work levels and practice costs is discussed, chiropractic practice is reviewed and a research and policy agenda for documenting chiropractic work, overhead and service descriptions is provided. METHODOLOGY: A manual systemic review of available recent and relevant medical and chiropractic literature was undertaken to characterize how the RBRVS system for reimbursement of physician services was developed and implemented. Payer and trade association literature was used to determine what established work value and practice costs for DCs there are. Published payment scales from governmental commissions were also obtained. CONCLUSIONS: Resources are urgently needed to survey levels of work by chiropractors in providing their various health services. The methodology should be the one used by the Health Care Financing Administration to assess other specialties. A range of generic manipulation codes should be developed and tested in a similar fashion for submission for inclusion in Physician's Current Procedural Terminology (CPT). A seed range of descriptions is presented. A systematic collection of practice overhead costs and malpractice risk should be undertaken and documented using standardized methodology.

The descriptive profile of low back pain patients of field practicing chiropractors contrasted with those treated in the clinics of west coast chiropractic colleges.

OBJECTIVE: To compare the demographic and clinical characteristics of low back pain patients from chiropractic college clinics and private practice settings on the west coast of the United States. DESIGN AND SETTING: A survey analysis of consecutive new patients in a specified time frame from multiple private office settings contrasted with a previous survey of consecutive new patients in a similar time frame from chiropractic college clinics. PATIENTS: In the private practice setting, new patients were selected on a consecutive basis as subjects for the study. Selection was limited to low back pain patients. INTERVENTIONS: None. This was a self-report survey only. MAIN OUTCOME: There is a strong similarity of the two low back pain patient groups, with the exception of higher levels of income, work time loss, severity and functional disability reported in the private practice setting. RESULTS: Similarities between the two low back pain patient groups were found in the distribution of gender, age, job description and education. Statistical significances were not determined due to variations in data collection. CONCLUSIONS: The two patient populations are reasonably comparable in sociodemographic variables, but clinical variation does exist. These results suggest the need to consider clinical findings when extrapolating research findings in a college clinic setting to the chiropractic profession in general.

Intra- and interobserver reliability of passive motion palpation of the lumbar spine.

Sixty student volunteers were assessed for fixation in the lumbar spine using a passive motion palpation protocol. Subjects were examined in random order by two experienced chiropractors. Every subject was evaluated twice by each examiner. Fixations were judged present or absent for each of five lumbar motion segments. Moderate test-retest agreement beyond chance was noted at L1/2, minimal reliability at L4/5, and no significant agreement within examiners was detected for mid-lumbar segments. Interexaminer agreement beyond chance was poor for all segments assessed. When segments were grouped regionally and re-evaluated, some increase in intrarater agreement was evident, especially at L4/5/S, but interrater agreement was still absent.

A meta-analysis of clinical trials of spinal manipulation.

OBJECTIVE: To assess the efficacy of spinal manipulative therapy (SMT) in the treatment of back pain using meta-analytical techniques. DATA SOURCES: The literature was systematically searched for all studies of SMT through June 1989. The Index Medicus from 1980 was expanded by citation tracking. The Chiropractic Research Archives Collection was utilized as a regularly updated bibliographic source for the location of research publications. A hand search of professional chiropractic journals was also undertaken. STUDY SELECTION: Studies in English with concurrent controls treated by methods other than SMT, including sham, produced 23 randomized controlled clinical trials of the effectiveness of spinal manipulation. Because a single trial might include more than one comparison of treatments, these trials produced a total of 34 mutually exclusive, discrete samples. DATA EXTRACTION: Data were extracted via a standardized coding document by one author and verified by two of the others. Data were independently extracted from a subset of the studies by a blinded research assistant to ensure that coding methods produced acceptable consistency. DATA SYNTHESIS: Effect sizes (Cohen's D index) were calculated for nine outcome variables at eight time points following the initiation of treatment. Thirty-eight of 44 effect sizes indicated that SMT was better than the comparison treatment. It was also found that meta-analysis was an imperfect instrument for the kind of trials that were pooled in this study because the research protocols were highly diverse. Furthermore, because the nature of SMT does not permit an easy use of placebos, true no-treatment control groups were rare. Most studies compared SMT to an alternative treatment. This probably obscured the effectiveness of SMT since the comparison treatments were presumably also effective. CONCLUSIONS: SMT proved to be consistently more effective in the treatment of low back pain than were any of the array of comparison treatments. The analysis provided some suggestion that manipulation, as such, is more effective than mobilization, as such. For the future, it is suggested that researchers strive for more consistent measures in terms of explicit descriptions of the nature of SMT, the times of post-treatment assessments and the nature of outcome measures. Only then can meta-analysis fulfill its potential in this clinical area.

Health services research related to chiropractic: review and recommendations for research prioritization by the chiropractic profession.

PURPOSE: This project was part of a national, federally sponsored effort to create a prioritized research agenda for the chiropractic profession. An overview (and a separate comprehensive annotated bibliography) of recent social sciences, medical, chiropractic and health services research literature regarding chiropractic is presented. Based on this information, key research questions and issues were identified in the areas of health services research, practice environments and account ability/quality management. Research issues were prioritized by a multidisciplinary panel. METHODS: Qualitative review of literature gathered through searches of electronic health care database retrieval systems and citation tracking. Nominal group-process methodology with an expert panel was used to identify research priorities from a comprehensive list of potential health services research questions. RESULTS: Six recommendations for a health services research agenda for the chiropractic profession were made: determine barriers to usage of chiropractic; develop models to explain chiropractic usage; determine cost-effectiveness of different chiropractic procedures; develop valid measures and predictors of quality of chiropractic care; and examine satisfaction with chiropractic services from patients, other providers, purchasers, etc.
