Associations Between Time to Reduction and Complications in Patients With Dislocated Total Hip Arthroplasty

Associations Between Time to Reduction and Complications in Patients With Dislocated Total Hip Arthroplasty - A Protocol for an Observational Cohort Study

The aim of the study is to investigate the impact of time to closed reduction on both patient related and organizational factors. These include, length of stay, hospitalization, admission to intensive care unit, rehospitalizations, delirium, all-cause mortality, infection requiring hospital contact, and cardiovascular complications. It is also intended to investigate whether different anaesthetic strategies and airway management are associated with different complication rates.

It is hypothesized that longer waiting time until reduction increase the postoperative length of stay, readmissions, and risk of complications.

Inclusion Criteria:

Patients will be considered eligible for inclusion if they meet all of the following criteria:

• Aged 18 years or older
• Presented to the emergency department with a dislocated total hip arthroplasty.
• Undergo closed reduction of the dislocated total hip arthroplasty in the operating theatre, with the involvement of the Department of Anesthesiology.

Exclusion Criteria:

• Were primarily booked for open surgical reduction.
• Did not have a complete case log (i.e. time of admission; referral to the operation theatre; anesthesia induction; discharge, etc.) and we were unable to recreate the log using simple code rules.
