Routine patient assessment and the use of patient-reported outcomes in specialized palliative care in Japan

Discrepancies in symptom assessment between providers and patients are reported in cancer care, and the use of patient-reported outcome measures (PROMs) has been recommended for patients receiving palliative care. However, the status of the routine use of PROMs in palliative care in Japan is presently unclear. Therefore, this study aimed to clarify this complex question. To this end, we administered a questionnaire survey either online or via telephone interviews (questionnaire: sent to 427 designated cancer hospitals, 423 palliative care units [PCUs], and 197 home hospices; interviews: conducted at 13 designated cancer hospitals, nine PCUs, and two home hospices).

Questionnaires were returned from 458 institutions (44% response rate). We found that 35 palliative care teams (PCTs, 15%), 66 outpatient palliative care services (29%), 24 PCUs (11%) and one (5%) home hospice routinely used PROMs. The most frequently implemented instrument was the Comprehensive Care Needs Survey questionnaire. Moreover, 99 institutions (92%) that routinely used PROMs responded these instruments as useful in relieving patients' symptoms; and moreover, the response rate in regard to usefulness in symptom management was higher than that of institutions that did not routinely use PROMs (p = 0.002); > 50% of the institutions that routinely used PROMs stated that use of these instruments was influenced by disease progression and patients' cognitive function. Moreover, 24 institutions agreed to be interviewed, and interviews demonstrated the benefits of and the barriers to the implementation of PROMs. Effective methods used in the implementation of PROMs were introduced as efforts to reduce the burden placed on patients and to promote healthcare providers' education in the use of PROMs.

This survey quantified the status of the routine use of PROMs within specialized palliative care in Japan, revealed barriers to wider PROM use, and identified needed innovations. Only 108 institutions (24%) routinely used PROMs within specialized palliative care. Based on the results of the study, it is necessary to carefully consider the usefulness of PROs in clinical palliative care, perform careful selection of PROMs according to the patient's condition, and evaluate how specifically to introduce and operate PROMs.
