A call for quality

Performance and quality measurement in occupational health services: current status and agenda for further research

BACKGROUND

There is growing interest in evaluating the impact and effectiveness of occupational healthcare services (OHS). Managed care networks, case and disease management, worker health promotion, and utilization review services have proliferated in OHS, usually without scientifically based, objective measures of their impact on the quality of care, outcomes, or costs. Performance and quality improvement (QI) efforts in OHS are different from those in general health care because the population, range of conditions, setting of care, and primary outcomes of interest differ considerably. However, scientific knowledge resulting from the application of QI in general health care can provide a useful framework for the development of measures in OHS.

METHODS

We describe the development, selection, and evaluation of OHS performance and quality measures, and propose a research agenda.

CONCLUSIONS

Quality and performance measures in OHS should address common work-related conditions with high costs, suboptimal outcomes, or unclear parameters for ideal practices. They should reflect stakeholder priorities. Measures should be precise and quantifiable, clearly specified, reliable, valid, and sensitive to important changes. They should be based upon data that can be collected and analyzed at a reasonable cost and effort. The focus of measurement should be on situations where improvement can be achieved by those directly involved in OHS delivery, through defined approaches. Appropriate severity and case-mix adjustment may be especially problematic in OHS. Confidentiality, regulatory concerns, and appropriate use of results must be considered in the development and use of OHS measures. Research is needed to identify, develop, and validate OHS-specific measures, to establish risk adjustment methods, and to test the utility of this information in improving OHS.

Occupational health and safety management systems in the Canadian pulp and paper industry: methods of auditing

The Canadian Pulp and Paper Association has developed eight "Guiding Principles for Management of Occupational Health and Safety" (OH&S) for its member companies. As part of a study to assess member companies' OH&S activities, an on-site audit was performed for 11 sites. The audit assessed five key components of a management system for a number of OH&S activities. Management-system components more likely to be in place included system ownership and goals and procedures, whereas measures of performance, a review of measures, and corrective action were less likely to be present. Environmental surveillance and injury reduction were most actively monitored, as indicated by the number of measures of performance relating to these activities. The auditing process demonstrated leadership and communicated the OH&S priorities of the Canadian Pulp and Paper Association to the sites.

Design of a state-based workers' compensation information system

BACKGROUND

California policy makers have long been hampered by a lack of credible information for use in making legislative or administrative changes to address serious problems in the workers' compensation system. In 1993, the legislature directed the California Division of Workers' Compensation to develop a Workers' Compensation Information System (WCIS).

METHODS

An advisory committee developed key questions and identified data sources regarding injury/illness incidence, costs, promptness of benefit delivery, adequacy of benefits, satisfaction with services, and other outcomes.

RESULTS

Key data elements were identified, mostly from existing mandated reporting forms for employers and physicians, and from standardized medical billings. Data collection will be carried out using: 1) rapid electronic data interchange (EDI) for a minimum number of data elements; 2) electronic collection of data on medical services for a sample of claims; and 3) surveys to address adequacy of benefits, satisfaction with services, return to work, and other outcomes. A state-based repository will analyze data and provide de-identified public use data files.

CONCLUSIONS

The proposed WCIS will provide information to improve the performance and to increase the accountability of all the participants in California's Workers' Compensation system. More importantly, it will provide information which will allow improved quality in the provision of mandated benefits to injured workers.
