AB  - AIMS: It is not known whether change in patient-reported outcome measures (PROMs) 
      over time can be predicted by factors present at surgery, or early follow-up. The 
      aim of this study was to identify factors associated with changes in PROM status 
      between two-year evaluation and medium-term follow-up. PATIENTS AND METHODS: 
      Patients undergoing Birmingham Hip Resurfacing completed the Veteran's Rand 36 
      (VR-36), modified Harris Hip Score (mHHS), Tegner Activity Score, and Western 
      Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at two years and a 
      minimum of three years. A change in score was assessed against minimal clinically 
      important difference (MCID) and patient-acceptable symptom state (PASS) 
      thresholds. Binary logistic regression was used to assess the relationship 
      between patient factors and deterioration in PASS status between follow-ups. 
      RESULTS: Overall, 18% of patients reported reductions in mHHS total score 
      exceeding MCID, and 21% reported similar reductions for WOMAC function scores. 
      Nonetheless, almost all patients remained above PASS thresholds for WOMAC 
      function (98%) and mHHS (93%). Overall, 66% of patients with mHHS scores < PASS 
      at two years reported scores > PASS at latest follow-up. Conversely, 6% of 
      patients deteriorated from > PASS to < PASS between follow-ups. Multivariable 
      modelling indicated body mass index (BMI) > 27 kg/m(2), VR-36 Physical Component 
      Score (PCS) < 51, VR-36 Mental Component Score (MCS) > 55, mHHS < 84 at two 
      years, female sex, and bone graft use predicted these deteriorating patients with 
      79% accuracy and an area under the curve (AUC) of 0.84. CONCLUSION: Due to 
      largely acceptable results at a later follow-up, extensive monitoring of multiple 
      PROMs is not recommended for Birmingham Hip Resurfacing patients unless they 
      report borderline or unacceptable hip function at two years, are female, are 
      overweight, or received a bone graft during surgery. Cite this article: Bone
