Medication safety management, Hospital, Medical error, Instrument development


This study aims to generate scale items for the measurement of quality medication safety management in hospitals and to verify the scale in terms of validity and reliability. The development and evaluation process was based on the scale development guidelines by DeVellis. The literature review and interviews with five experts provided a framework for item formulation. Another five experts evaluated the content validity of the instrument. 481 registered nurses completed the questions in the instrument, and the data from the registered nurses were then analyzed to evaluate the construct validity using factor analysis and to test for reliability indexes. The results revealed that there were 48 items constituting the scale whereby to measure the quality of medication safety management in hospitals. The items were grouped into six components of medication safety management: drug prescription, drug dispensing, drug administration, high-alert drug management, medical error management, proactive drug safety management. The data on reliability supported a good internal consistency (Cronbach alpha coefficient was .83). The construct validity was confirmed by a six component model of medication safety management as a good measure of quality in medical safety management (RMSEA < .048, χ2/d.f. =1.73, NFI= .899, CFI = .98, PNFI = .91).
