ABSTRACT Objectives: To develop and validate in an Australian setting, an instrument to effectively measure patient safety culture; to survey health care workers (HCWs) in a large public healthcare system to establish baseline patient safety culture; and, using the Theory of Planned Behaviour (TPB), to use behavioural modelling to identify the factors that predict and influence Patient Safety Behavioural Intent (PSBI) Eg. Reporting clinical incidents and speaking up when a colleague makes an error. Design: Cross sectional survey analysed with multiple logistic regression (MLR). Setting: Metropolitan, regional and rural public hospitals in Queensland, Australia. Participants: 5294 clinical and managerial staff. Main outcome measures: 1) Behavioural models for high-level Patient Safety Behavioural Intent (PSBI) for senior and junior doctors, senior and junior nurses, and allied health professionals. 2) Odds ratios to compare levels of PSBI between professional groups. Results: 1) The factors that influence high-level PSBI for each professional group give rise to unique predictive models. Two factors stand out as influencing high-level PSBI for all HCWs (R2 0.21). These are: i) Preventive Action Beliefs (Adjusted Odds Ratio (AOR) 2.38) (HCWs??? belief that engaging in the target behaviour(s) will lead to improved patient safety) and ii) Professional Peer Behaviour (AOR 1.79) (HCWs??? perceptions of the safety behaviour(s) of one???s professional peers). 2) There was a six-fold difference in the level of target behaviour (PSBI) across the clinical groups with few (29.6%) junior doctors having a high-level of PSBI. When compared with the junior doctors, the senior doctors were nearly 1.5 times more likely (Odds Ratio (OR) 1.46, 95% Confidence Interval (CI) 1.01-2.13), allied health staff 2.7 times more likely (OR 2.71, 95%CI 1.91-3.73), junior nurses 3.9 times more likely (OR 3.86, 95%CI 2.83-5.26), and senior nurses 6.0 times more likely (OR 6.01, 95%CI 4.78-9.16) to have high-level PSBI. Conclusions: This is the first published study to develop behavioural models of factors that influence HCWs??? intention to engage in behaviours known to be associated with improved patient safety. The findings of this study will greatly assist in the future design and implementation of targeted and cost-effective patient safety improvement initiatives.
