The Q-REDUCE Study

A Quick Pathway for Patients With High pRobability of dislocatEd Hemi- or Total Hip Arthroplasty to Minimize the Time From Hospital aDmission to redUCtion of the prosthEsis

The purpose of this study is to design a fast-track pathway for patients referred to the University Hospital of Southern Denmark, Esbjerg, with high probability of having a dislocated hip prosthesis with the primary aim to reduce the time from arrival to reduction and the total hospitalization time. Secondary aims are to

• investigate whether quicker prosthesis reduction influences on hip function and quality of life afterwards
• reduce the pain experience immediately and in the long term
• increase patient satisfaction

without changing the overall complication rate and readmission/mortality

Inclusion Criteria:

• a history of either a THA or a HA in combination with at least one of the following terms
• having sustained a sudden, incorrect movement or twist in the hip joint in either a bending, sitting or supine position leading to inability to stand or walk
• misalignment of the concerned lower extremity (typically shortened, with inward/outward rotation)

Exclusion Criteria:

• recurrent dislocations during the same hospital admission (already "in the house")
• anticipated difficult airway by the attending anesthesiologist
• anticipated need for extended respiratory or hemodynamic monitoring by the attending anesthesiologist
• American Society of Anesthesiologists (ASA) score > 3
• Body Mass Index (BMI) > 40
• active drug abuse
• contraindication for Propofol or Esketamine
