Introduction 20% hospital incidents were caused by errors of medications. (Malpass et al., 1999) 17% hospital incidents were involved in medication errors. (Australian Quality of Health Care Study, 1995) Medications: iatrogenic injury and illness (Bates, 1999)

(O”Shea, 1999)

176 nurses 11 public sector hospitals 41-50 years old: 33.5% 92% females 10 years experience with Queensland Health: 59.1% Work for over 20 years: 21.6%

Conclusions Errors and violations are different. Violations: not intended to do harm Stress was a significant mediator. Excessive workload and expectations of doctors increased the frequency of medication violations. No evidence showed that nurses are less safety- conscious than workers in other high-risk industries. Regular monitoring of organizational, safety climate and levels of individual distress and morale is helpful for achieving better health outcomes for everyone.
