Usability Assessment of Laboratory Data Printed on the Prescription for Outpatients

Abstract

530 緒 言 病院や診療所による電子カルテの導入は，多職 種による患者情報の閲覧を可能とした．従来であれ ば処方せんから読み取れる患者情報は処方内容を 除けば生年月日，性別，年齢程度であったが，電子 カルテの閲覧により身長・体重，疾患名，臨床検査 値，医師の診察内容等ほぼ全ての情報が入手でき るようになった．そのため，実測体重からの適正投 与量の算出や臨床検査値を基にした客観的な治療 効果・副作用の評価が可能になり，病院や診療所 に勤務する薬剤師の処方監査はより高度になった． 1） ＊ 〒910-1193 福井県吉田郡永平寺町松岡下合月23-3 医療薬学 40(9) 530―536 (2014) We disclosed laboratory data on the prescription for outpatients from April 2011. In order to evaluate the usefulness of this approach, we regularly have meetings with pharmacists of plural outpatient pharmacies. We analyzed the data that was accumulated to investigate the usage of laboratory data and related medicines. As a result of the questionnaire to pharmacists of the outpatient pharmacy, more than Nineteen in twenty two pharmacists (19/22) checked prescriptions and patient instructions using the laboratory data. The high-frequency laboratory data printed on the prescriptions were Prothrombin Time -International Normalized Ratio (PT-INR) value, the serum creatinine value and the serum potassium value. When the pharmacists felt uncertain about usage related with laboratory data in prescriptions, they gave suggestions to the doctor. Approximately 40％ of pharmacist＇s suggestions were accepted by the doctor. Printing of the laboratory data could become a helpful tool in cases of uncertainty. However, there were cases in which there were differences in recognition of the examinations results among pharmacists, especially in the outpatient pharmacy. Therefore, we need information sharing and reinforcement of cooperation with the outpatient pharmacy.
