The goal of this project is to improve nurse treatment integrity for emergency gastrointestinal (GI) bleeding to prevent bleeding related comorbidities. The initial analysis indicated that treatment integrity for emergency GI bleeding in our institution was 57.0 %. The low treatment integrity could be attributed to unfamiliarity of treatment procedures, lack of standard operating procedure for caring emergent GI bleeding, incomplete educational training, and disorganized material storage, which can lead to prolonged preparation time. Improvements were implemented by establishing a care procedure for emergent GI bleeding and a personal card for bleeding treatment, and a treatment package, as well as revising the education and training programs. After implementing the project, the treatment integrity for emergent GI bleeding increased significantly from 57.0% to 98.2%. The results of this project demonstrated that the care abilities of nurses for treating emergent GI bleeding and quality of clinical care can be improved by implementing appropriate strategies.
