The core outcomes for open lower limb fracture study

Abstract

Aims A core outcome set for adult, open lower limb fracture has been established consisting of Walking, gait and mobility , Being able to return to life roles , Pain or discomfort , and Quality of life . This study aims to identify which outcome measurement instruments (OMIs) should be recommended to measure each core outcome. Methods A systematic review and quality assessment were conducted to identify existing instruments with evidence of good measurement properties in the open lower limb fracture population for each core outcome. Additionally, shortlisting criteria were developed to identify suitable instruments not validated in the target population. Candidate instruments were presented, discussed, and voted on at a consensus meeting of key stakeholders. Results The Wales Lower Limb Trauma Recovery scale was identified, demonstrating validation evidence in the target population. In addition, ten candidate OMIs met the shortlisting criteria. Six patients, eight healthcare professionals, and 11 research methodologists attended the consensus meeting. Consensus was achieved for the EuroQol five-dimension five-level Questionnaire (EQ-5D-5L) and the Lower Extremity Functional Scale (LEFS) to measure Quality of life and Walking, gait and mobility in future research trials, audit, and clinical assessment, respectively. No instrument met consensus criteria to measure Being able to return to life roles and Pain or discomfort . However, the EQ-5D-5L was found to demonstrate good face validity and could also be used pragmatically to measure these two outcomes, accepting limitations in sensitivity. Conclusion This study recommends the LEFS and EQ-5D-5L to measure the core outcome set for adult open lower limb fracture.
