A cross-sectional study was performed in 247 Thai hospitals. Questionnaires eliciting demographic
data and information on injury occurrence and risk factors were distributed to 2500 operating
room nurses, and 2031 usable questionnaires were returned, for a response rate of 81.2%. Adjusted
odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using multiple logistic regression
analysis.
