Risk of work related injuries experienced in a six month period by public hospital based workers (n = 475) by organisation and occupational factors; Costa Rica, 2000
| Variable (reference) | Work related injuries | ||||||
|---|---|---|---|---|---|---|---|
| n | % | Rate | RRc | 95% CI | RRa | 95% CI | |
| RRc, crude rate ratio of work related injuries; RRa, adjusted rate ratio for the significant (p<0.05) variables on the bivariate crude analysis. | |||||||
| *Two separate logistic regression models were developed: one model included safety practices and safety climate as separate variables, and the second model included the combined variable of safety climate and safety practices. The estimations for the second model did not vary significantly so data for the rest of covariates presented in the table correspond to results using the first model. | |||||||
