Availability of patient classification using clinical data.

Objectives: The aim of this study is examine the reliability and validity of the patient classification which is based on clinical data with comparing to nurse's check.

Method: Nurse Experts estimated the content validity of extracting KPCS-1(Korea patient classification system for nurses Version 1) activities score from clinical data in storage of AMIS (Asan Medical Center information system). After verifying the content validity of extraction method from clinical data, two methods extracting KPCS-1 score (from clinical data vs. nurses' recording) were compared for 348 patients.

Results: This study demonstrated that extracting patient classification from clinical data is high value of validity (except 4 items excluded from this study), reliability between two methods extracting KPCS-1(from clinical data and nurses' recording) is high value (ICC=0.96, p<.001) and construct validity of two methods has similarity.

Conclusions: It is believed that the patient classification system which is made from only clinical data without nurse's work burden is available. And 4 items which was excluded on KPCS-1 and examine area which had low level of reliability are needed to be amended.
