Abstract
Abstract Objective: To study the errors in laboratory requests in the In-Patient Department of Chulalongkorn Hospital.
Design: Serial cross sectional descriptive study
Materials and methods: Laboratory requests from the In-Patient Department sent to the Clinical Chemistry Unit, Division of Laboratory Medicine, Chulalongkorn Hospital were considered using criteria based on textbooks of laboratory medicine. Obtained data were analyzed and interpreted.
Results: The major errors in request forms were in complete due to omissions, mistakes and use of non-standard abbreviations. Many errors were observed in aspects of the time that specimens were collected, diagnosis and patient identification. But less than 1% of the specimens were considered inappropriate. It revealed that the errors of the laboratory requests decreased after the promotion of rational and correct laboratory request.
Conclusions: Incomplete laboratory request form writing was the major error found in laboratory requests. Medical personnel should be more careful in writing request forms and in specimen collection.
