Objective Based on the theory of Information-Knowledge-Attitude-Practice(IKAP),the reliability and validity of the discharge preparation scale for patients with diabetic foot(DF)was developed and tested,which is in accordance with the national conditions and disease characteristics of our country.Methods Based on the IKAP theoretical framework,articles were identified through literature analysis,qualitative interviews and Delphi method.After pre-investigation,a total of 483 patients with DF were selected from 3 general hospitals in Jiangxi province from June 2023 to February 2024.The items were screened by item analysis,and the reliability and validity were tested.Results The discharge preparation scale for patients with DF included 4 dimensions and 29 items.The Cronbach's α coefficient was 0.934;the scores of each dimension Cronbach's α coefficient ranged from 0.889 to 0.947;the overall split-half reliability was 0.966,and the split-half reliability of each dimension ranged from 0.901 to 0.952.A total of 4 common factors were extracted by exploratory factor analysis,and the cumulative contribution rate of variance was 68.074％.The x2/df value of confirmatory factor analysis was 1.906.The fitting fit of the model is suitable.The content validity was 0.973 at scale level and 0.875～1.000 at item level.Conclusion The reliability and validity of the discharge preparation scale for patients with DF are good,and it can be used as a tool to evaluate the discharge preparation for patients with DF.

This article reviews the construction methods, basic contents, advantages and disadvantages of the self-management assessment tools for patients with diabetic foot at home and abroad, which provides a reference for selecting the most appropriate assessment scale according to age groups and research purposes in clinical application, as well as developing and translating the rigorous, scientific, accurate and comprehensive patient self-management scale into Chinese according to different age groups and disease grades, which is consistent with China's national conditions. In order to improve the prognosis of patients with diabetic foot through personalized intervention based on the assessment results.

Objective:Explore the open sharing mode of large-scale scientific instruments in specialized laboratories, consider how to effectively improve the use efficiency of instruments.Methods:Based on the analysis of the problems existing in the management of large scientific instruments in specialized laboratories of a general hospital, the open sharing platform of specialized laboratory instruments was constructed with the help of laboratory information management system, and relevant management suggestions and thoughts were put forward.Results:Depending on the system design, specialized laboratories can use the instrument sharing platform to implement the " special management sharing" of large scientific instruments and improve the efficiency of instrument use.Conclusions:The construction of large scientific research instrument sharing platform for specialized laboratories in general hospitals is an effective means to solve the instrument management problems in specialized laboratories at present, but to give full play to the effect, it is necessary to constantly improve the platform system construction and technical personnel training.
