Analysis of Hospital worker injury rates using results from OSHA Data Initiative: 1996-2011
The primary objective is to provide a general descriptive analysis of the dataset for General and Surgical Medical Hospitals (NAICS 622110). The secondary objective is to explore a multilevel model to describe changes in incident rates over time and associations with State level variables, including unemployment and Union representation.
Injury and illness incident rates were calculated from log data and structured as an unbalanced panel. Unemployment and union rates were joined by State and sample year as time variant predictors. Exploratory multilevel models were created for unconditional means and growth to assess variation at time of first report, and variations within and between hospitals.
The final dataset contained 484 General Hospitals with 2570 combined records for the period 1996 through 2011. The TCR across the dataset averaged 11.6 per 100 full time employees, cases of DAFWII averaged 3.4, and DART cases averaged 5.8. Preliminary results indicate that 30% of the total variance is attributed to differences among hospitals. There is a significant negative effect of time where for each reporting year following the first the total incident rate decreases by approximately 1 case per 100 full time employee. The level of first reported TCR is shown to affect the rate at which incidents decrease over time. There were no indications that State level union representation or unemployment rates as fixed effects impacted injury or illness.
