慢性病患者基层用药体验量表研制及其信效度检验

Background  Improving the patient medication experience is a key factor in improving patient medication adherenceand it is also necessary to improve patient outcomes and medical safety. At presentthere is a lack of measurement tools for the primary medication experience of patients with chronic diseases in Chinawhich seriously restricts the research and practice of pharmaceutical service and management in primary medical institutions. Objective  The purpose of this study was to develop the Primary Medication Experience Scale for Chronic Disease Patientswhich is applicable to the practice of chronic disease management in Chinaand to conduct reliability and validity testswith the aim of providing instrumental support for research and practice of health management for chronic disease patients. Methods  This study used a combination of qualitative and quantitative methods to develop the scale. Firsta pool of scale items was generated through the literature review methodand a preliminary primary medication experience scale for patients with chronic diseases was formed through the semi-structured interview method and under the guidance of the perceived value theory. Through the Delphi expert consultation methodthe preliminary primary medication experience scale for patients with chronic diseases was consulted and validatedand revised and improved. In October 2023a random sampling method was used in primary healthcare institutions in Shandong Province to select chronic disease patients attending primary healthcare institutions for on-site researchto debug the scale in terms of language and culture and to test the reliability and validity of the scaleand to make further optimization and adjustment of the scaleto finally form the Scale of Experience of Primary Medication Use for Chronic Disease Patients. Results  14 dimensions related to medication experience were extracted through literature reviewand a pool of 40 items in 8 dimensions was initially constructed through semi-structured interviews. The scale was modified and improved through the Delphi expert consultation methodand the two rounds of expert positivity were 95% and 100%and the mean values of expert authority coefficient were 0.86 and 0.88respectivelyand the experts put forward more scientific and authoritative modification opinions and suggestions on the scaleforming a scale containing 29 items in 7 dimensions. Conclusion  The primary medication experience scale for chronic disease patients developed in this study has good reliability and validityhas certain local appropriateness and scientific validityand can be used in the survey research of primary medication experience for chronic disease patients.
