Background & Aim: Out of hospital interventional orthopaedic and regenerative medicine (IORM) procedures are a new addition to the subspecialty of interventional radiology. This study aimed to assess health outcomes following IORM procedures in an outpatient integrated service delivery model in clinical practice.Methods: Retrospective study of all patients who completed the pre- and post-procedure EuroQol 5D5L questionnaire over a 6 month period.Results: Forty-eight patients (age range=32-89, mean=60.5, median=63.5 years) were eligible. Mean and median pre-treatment EQ5D5L index values of 0.53 and 0.61(range: -0.248 to 0.879, SD: 0.28, 95% CI: [0.45, 0.61]) improved to 0.73 and 0.73 (range: 0.414-1.0; SD: 0.13, 95% CI [0.69, 0.76]) (p < 0.01, Cohen ‘d’ = 0.93) post-treatment. Improvements in ‘no problems’ in each health dimension were: pain (mathematical infinity), mobility (109%), usual activities (137.5%), self- care (56%), anxiety/depression (23.3%). Reductions in ‘any problems’ in each dimension of health were: pain (-14.5%), mobility (-32%), usual activities (-27.5%), self-care (-60.87%), anxiety/depression (-38.8%). Pre-treatment, a strong negative correlation between EQ5D5L index values versus mobility levels (r = -0.67, p < 0.01) and versus usual activities (r = -0.62, p < 0.01) was present. Post-treatment, a strong negative correlation between EQ5D5L index scores versus pain level (r = -0.68, p <0.01) and versus mobility (r = -0.75, p <0.01) was present.Conclusion: Significant improvements in all health dimensions with a large treatment effect was shown following outpatient IORM procedures in an integrated interventional radiology service delivery model. Improvements in mobility and pain were the most important determinants of health.
