Patient Safety Culture scores

Clearly more empirical studies are needed linking patient safety culture scores to patient safety and quality outcome data Such studies should examine linkages at the hospital level and at the unit level where relationships may be stronger. The difficulty of this research is that large numbers of hospitals with both safety culture and outcome data are needed to detect these relationships. 

In IRT, on the other hand, a latent trait, such as patient safety culture , is an unobserved construct measured by a set of observed items. The unobserved construct, in this case patient safety culture , has a causal relationship to the observed scores . Thus, CTT tends to focus more on total test scores, whereas IRT focuses on the items and their characteristics (Borsboom 2005). CTT is useful when the test score is of central interest, while IRT is most useful in examining the individual building blocks (items) of the total test scores. Both have their strengths and both are needed to form a complete picture of the properties of a set of items. 

Several instruments have been developed to assess hospital staff s perceptions of aspects of workplace safety culture and a number of studies have reported associations between hospital safety culture and safety outcome measures (Jackson et al. 2010). Profiling the hospital safety culture scores is relatively straightforward but finding safety outcome measures for patients or workers is more challenging (Flin 2007). Different types of safety outcome data can be collected, e.g. (i) hospital incident records for staff or patients or clinical data for patients, (ii) self-reports of incidents and injuries by workers or patients and (iii) workers safety behaviours (self-reported or observed). 

Pharmacists were least positive on patient safety culture overall with an average percent positive score of 68 percent. Pharmacists also had the lowest ratings of their work area/unit as Excellent or Very Good (68 percent). However, pharmacists had the highest pereentage of staff reporting one or more events in the past 12 months (71 percent). 

Nonpunitive response to error Nonpunitive response to error remains the one patient safety culture composite that consistently scores at the bottom for virtually all hospitals, year after year. Staff continue to worry that the mistakes they make are kept in their personnel file, that individuals are written up rather than the problem and that their mistakes are held against them. Many hospitals have... 

An early criticism of patient safety culture survey data was that there was not sufficient evidence that culture was related to medical error, patient safety or quality or patient outcomes. There are still very few empirical studies linking the Hospital SOPS to these important outcomes and many more studies are needed. However, there have been a few key studies showing positive relationships between Hospital SOPS scores and outcomes. 

Differences in scores across countries may be due to a number of factors other than true differences in patient safety culture, making direct comparisons between countries complicated. The first factor is the quality and comparability of translations. Translations must convey the intent of the original items rather than merely directly translating the words and translations should undergo cognitive testing and validation before use. Most international administrations of the survey have shown similar factor stiuctures to the US version and acceptable psychometric... 

In order to identify areas of organisational culture that could be targeted to improve patient safety in Scottish hospitals, a safety culture survey was conducted. The aims of the study were first, to obtain a measure of safety culture from a sample of NHS acute hospitals in Scotland and then to test whether these culture scores were associated with clinical workers safety behaviours and patient and worker injuries. This would also provide a measure of safety culture within the Scottish acute hospital sector and contribute an organisational cultural perspective to the...
