Official title
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
Overview
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
Interventions
- Other Fasttrack pathway for THA/HE prosthesis reduction
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. The intervention is changed logistic and work pathways at the hospital that should reduce time to reduction significantly. For detailed description we refer to the uploaded protocol. - Other Standard pathway for THA/HE prosthesis reduction
Standard treatment for a dislocated THA/HA at our institution is education in general anesthesia at the operating theater. For detailed description we refer to the uploaded protocol.
Primary outcome measures
- Time from arrival at the emergency entrance to prosthesis reduction [Time frame: 1 year]
Secondary outcome measures (11)
- Total hospitalization time from arrival to discharge [Time frame: 1 year]
- Intra-operative complications (fracture, unsuccessful reduction, aspiration, need for mask ventilation and/or intubation, others) [Time frame: 1 year]
- Post-operative complications (cardiac, pulmonal, thrombo-embolic events, nerve damage, re-dislocation, others) during hospitalization [Time frame: 1 year]
- 30 days re-admission [Time frame: 30 days]
- 30- and 90-days mortality [Time frame: 30 and 90 days]
- Hip-related pain measured by a 10-digit numeric rating scale (NRS) [Time frame: Day 0, 1, 3, 7, 14 and 30]
- Patient-reported outcome (PRO) using the Hip disability and Osteoarthritis Outcome Score (HOOS), [Time frame: Day 0, 14, 90, 180 and 365]
- Health-related quality of life using the EQ-5D questionnaire [Time frame: Day 0, 14, 90, 180 and 365]
- Patient satisfaction [Time frame: During hospital admission, day 1.]
- Time consumption by the involved staff (orthopedic, anesthetic, radiology staff etc.) [Time frame: 1 year]
- Total hospital costs during admission [Time frame: 1 year]
Eligibility criteria
Inclusion criteria
- a history of either a THA or a HA in combination with at least one of the following terms

Exclusion criteria
- recurrent dislocations during the same hospital admission (already "in the house")
