Purpose To discover the training effectiveness of community nurses' cognition of pressure injury on the nursing linkage Methods Guided by KAP (Knowledge, Attitude and Practice) Theory, and under the background of medical consortium in our hospital, we built a pressure injury nursing linkage platform dominated by mobile learning, supplemented by offline guidance and sharing of high-quality resources in the hospital, and trained 66 clinical nurses in 6 community health service centers of the medical consortium The theoretical knowledge, attitude, and clinical care behavior questionnaire of community nurses with pressure injury were surveyed after 18 months of platform operation and measured nurses' satisfaction with the platform and self- Results The theoretical knowledge, attitude, and clinical nursing behavior of 66 community nurses with pressure The theoretical knowledge, attitude, and clinical nursing behavior of 66 community nurses with pressure injury compared before and after the platform operation, and the difference was statistically significant (P<0.05) ; Satisfaction with the platform was 91% for 5 items; Among the 10 items of self-evaluation of community nurses, the highest percentage of "agree" was to gain new knowledge and Among the 10 items of self-evaluation of community nurses, the highest percentage of "agree" was to gain new knowledge and change philosophy, which was 100%. And 80% of the nurses agreed that they would change their incorrect nursing behaviors after the training. Conclusion After the training of all 66 After the training of all 66 community nurses through the nursing linkage platform, their theoretical knowledge of pressure injury had significantly improved; Established After the training of all 66 community nurses through the nursing linkage platform, their theoretical knowledge of pressure injury had significantly improved; Established correct nursing concepts; Improved nursing behaviors; Satisfied with the training of nursing linkage platform.
