[A Prospective Clinical Study on the Continuation Rate of Recording Electronic Patient-Reported Outcomes and Electronic Medication Notebook by Patients and the Rate of Information Reference by Attending Physicians in Cancer Chemotherapy].

This prospective observational clinical study examined the adherence of patients with cancer undergoing outpatient chemotherapy to recording Electronic Patient-Reported Outcomes(ePRO)and using electronic medication notebooks, as well as the rate of information reference by attending physicians during outpatient consultations. Among 20 patients enrolled across 3 hospitals, including Kobe University Hospital, 18 consistently maintained ePRO and electronic medication notebook entries throughout the 180-day observation period. Post-observation interviews revealed that all attending physicians referred to a summary viewer integrating ePRO and electronic medication notebook data during outpatient consultations. The integration provided physicians with a more accurate understanding of patients' daily lives in a short time. These findings provide further evidence for the usefulness of ePRO and electronic medication notebooks for monitoring the health conditions of patients with cancer outside the hospital settings.
