Abstract

The number of death from lung cancer in Japan has ranked first since 1988 and tends to increase hereafter. However, there are few reports on value evaluation of palliative care for lung cancer patients with end-stage, especially the research is rare concerning medical economic evaluation related to palliative care. For performance analysis focusing on the ratio between utility and cost related to intervention of palliative care, it is indispensable to calculate Quality Adjusted Life Year that is one of outcome indexes. However, it is usually difficult to obtain data of health related quality of life (HRQoL) from the patients themselves at the end stage. Therefore, we verified appropriateness of proxy reporting of HRQoL by Health professionals (nurses). 16 lung cancer patients (aged 67.75±6.74) at the stage IV participated in the study. Euro-QoL Five-Dimension Questionnaire (EQ-5D) was reported for three days per patient. Proxy reporting of EQ-5D was executed by five certified nurses in the field of cancer nursing. Inter-rater agreement levels for the reporting of EQ-5D by patients and proxies were verified. The total score of EQ-5D was found to be statistically significant positive correlation between patients reporting and proxies reporting (Rs=0.654, p<0.01). Also, the scores for each item of EQ-5D had statistically significant positive correlation in “mobility”, “self-care”, and “pain/ discomfort” between patients and proxies (p<0.01). From the above, it is presumed that proxy reporting by nurses possesses certain explanation capability even at the end stage of lung cancer patients.
