Research summary
The Patient Measure of Safety (PMOS) questionnaire is a 44 item questionnaire which asks patients about factors that can contribute to patient safety incidents in hospital inpatient wards. It was developed by researchers at the Bradford Institute for Health Research as a data collection tool within the Patient Reporting and Action for a Safe Environment (PRASE) intervention.
PRASE is an intervention in which data is systematically collected from hospital patients and fed back to ward staff in a structured feedback report. This provides information for ward staff to use to create action plans, implement and monitor changes in line with the issues raised by patients.
To reduce the burden on patients, the PMOS questionnaire has been reduced in length from a 44 to a 30 item measure. The 30 item measure is currently being used within another project and is working well. However, hospital teams and managers have requested a shorter version of the PMOS which can be used for routine monitoring.
Using statistical modelling we have identified the 10 items from the 30 item questionnaire which seem to measure patient safety most accurately. The aim of this study is to test the PMOS-10 questionnaire with a sample of 200 patients to understand:
1. How long it takes to complete and how willing patients are to do so.
2. Whether the items within the questionnaire are highly correlated, indicating that they are measuring the same thing (patient safety). This is referred to as reliability.
3. Whether the measure is correlated with other measures of safety, such as safety culture (a staff completed measure) and the incidence of patient safety events. This is referred to as validity.Answering these questions will tell us whether the PMOS-10 is a useful measure.
