NCT04332055

Brief Summary

The randomised clinical trial investigates the effect of using a clinical decision support system (CDSS) aiming to provide the patients and surgeons with greater transparency concerning the obtainable changes in function and health related quality of life (HRQoL) when patients are to decide if they should undergo hip- or knee replacement surgery.

Outcome Measures

Primary Outcomes (2)

  • Oxford Hip Score

    The OHS is a short 12-item PRO questionnaire, which is specifically designed and developed to assess the primary outcome in randomised controlled trials with patients undergoing hip or knee replacement surgery. The questionnaires are reproducible, validated and sensitive to clinically important changes24. The primary outcome measure is the delta value in OHS, or OKS measured at baseline, defined as the first consultation in the clinic, and at 1-year follow-up.

  • Oxford Knee Score

    The OKS is a short 12-item PRO questionnaire, which is specifically designed and developed to assess the primary outcome in randomised controlled trials with patients undergoing hip or knee replacement surgery. The questionnaires are reproducible, validated and sensitive to clinically important changes24. The primary outcome measure is the delta value in OHS, or OKS measured at baseline, defined as the first consultation in the clinic, and at 1-year follow-up.

Interventions

ERVINOTHER

ERVIN is state of the art for IT systems, which uses artificial intelligence (AI) and real-time patient-specific PRO data to support patients and doctors in clinical decision-making. The system is designed for surgical OA treatment of knee and hip replacement, and can be used to predict outcome scores for the actual choice OA patients face in the patient trajectory; to choose surgery or not.

Masking Details
Patients are blinded from the randomisation, and blinding of the consulting surgeon is not possible since the intervention is an interface add-on to the conventional treatment.

Intervention Model
PARALLEL
Model Details: Patients will be randomised to the two intervention arms using a randomised block design stratified by age, Oxford Hip- or Knee Score at baseline and location of disability. Age and Oxford scores are subdivided into suitable categories20. Randomization will be done using REDCap electronic data capture21. Block sizes will be random with possible volumes of four and eight patients. Patients will be randomised after completion of the survey questions at the ePRO kiosk. Information regarding randomisation will be typed in separate REDCap module by the designated helper, after which a randomisation key is automatically generated, which can then be extracted by the designated helper, but blinded from the patient.
