RESUMO
PURPOSE: To analyze the responsiveness and the minimally clinical important change (MCIC) of the EuroQol (EQ) 5D-5 L score in patients that had undergone foot/ankle surgery. METHODS: Patients that underwent elective foot/ankle surgery from January 2019 to December 2020 were included. They were assessed with the EQ-5D-5L, visual analogue pain scale and Manchester Oxford Foot Questionnaire (MOXFQ) preoperatively and 1 year postoperatively. The pre-post differences of all variables, Effect Size (ES) and MCIC were analyzed. RESULTS: 167 patients. All variables showed a significant pre-post improvement. The ES for EQ-index and EQ-VAS were 0.61 and 0.33 respectively. MCIC for EQ-index was 0.17 and EQ-VAS was 8.54. MOXFQ index ES was 1.46 and the MCIC was 23.8. VAS decreased from 59.4 to 26.62. CONCLUSION: The EQ-5D-5L is a sensitive test to detect changes after elective foot and ankle surgery with good responsiveness relative to the ES values in the EQ-index. LEVEL OF EVIDENCE: II.
