Design of a state-based workers' compensation information system.

Area of Science:

• Workers' compensation system research
• Health services research
• Public policy analysis

Background:

• California policymakers lacked data to improve the workers' compensation system.
• The California Division of Workers' Compensation was tasked with developing a Workers' Compensation Information System (WCIS) in 1993.

Purpose of the Study:

• To establish a comprehensive Workers' Compensation Information System (WCIS) in California.
• To provide credible data for legislative and administrative improvements.
• To enhance the quality of mandated benefits for injured workers.

Main Methods:

• An advisory committee identified key research questions and data sources.
• Data elements were sourced from employer/physician reports and medical billings.
• Data collection will utilize electronic data interchange, electronic medical service data, and surveys.

Main Results:

• Key data elements for injury incidence, costs, benefit delivery, and outcomes were identified.
• A multi-pronged data collection strategy involving electronic and survey methods was established.
• A state repository will analyze data and provide de-identified public use files.

Conclusions:

• The Workers' Compensation Information System (WCIS) will improve system performance and accountability.
• WCIS will provide crucial information for enhancing the quality of benefits for injured workers.
