Immediate Inpatient Work-Related Hospitalization Surveillance System


A work-related immediate inpatient hospitalization is a work-related injury that leads to an inpatient hospital admission within 1 day of the injury event (based on day, not 24 hours). Cases are identified using 2 data sources – Washington workers’ compensation (WC) data and Washington’s hospital discharge data, the Comprehensive Hospital Abstract Reporting System (CHARS).

Public health importance of Immediate Inpatient Work-Related Hospitalization Surveillance

Immediate inpatient hospitalizations resulting from work-related injuries represent a small proportion of injuries, but are severe, costly, and preventable injuries that indicate a need for intervention. Acute traumatic injuries comprise a high proportion of Immediate inpatient hospitalizations. Employers throughout the United States are required to report work-related hospitalizations to their state or OSHA regional office, and characterizing these hospitalizations may be valuable both for prevention efforts and for assessing the completeness of employer reporting.

Purpose & Operations of Immediate Inpatient Work-Related Hospitalization Surveillance

Immediate Inpatient Hospitalizations data allows for:

  1. Quantifying prevalence by industry & occupation of work-related injuries and illnesses that lead to immediate inpatient hospitalizations
  2. Identifying high-risk occupations/industries and health disparities/risks;
  3. Aiding in targeting prevention efforts.

Employers, policymakers, and health promotion practitioners can utilize the study findings to target and prioritize prevention efforts for injuries most likely to cause an immediate work-related hospitalization.
