(P 072) ESTABLISHING A SARCOMA REFERENCE SCORE FOR EQ-5D

Objective: In April 2021, Switzerland introduced a law on quality and economics in the treatment of patients. In this context, patient-reported outcome measures are increasingly accepted and required to determine the quality of treatment of patients. There are many validated questionnaires covering a wide variety of aspects of life that are directly reported by the patients and independently of the clinical metrics as assessed by the physicians. The aim of this study was to establish a sarcoma reference score for EQ-5D, a standardized measure of health-related quality of life.

Methods: According to the EQ-5D, we requested a consecutive cohort of patients who were being treated for sarcoma or for suspected sarcoma, to judge their level of walking, self-sufficiency, usual daily activities, pain, and fear level. The patients were asked during a regular outpatient visit which was conducted either at a first-time presentation or follow-up visit. Overall, 634 consecutive patients were included in this analysis.

Results: The overall satisfaction level was 76.6% (range, 0 to 100%), with a median of 80%, and Q1/Q3 with 70%/90%. Summarizing all the scores of the five parameters, we found a mean score of 87% (range, 30 to 100), with a median of 90% and Q1/Q3 of 80%/100%.

Conclusion: A health-related quality assessment of daily living in a consecutive series of sarcoma patients in an outpatient setting is possible. The level of satisfaction of this cohort of sarcoma patients is satisfactory overall. We will now further detail the analysis focusing on the patient parameters, tumor parameters, and treatment parameters.
