About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

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.

Disqualifiers

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.

Trial population

The cohort contains all adults presenting with a dislocated THA, who underwent closed reduction in an operating theatre with anesthesiology being involved, in public hospitals in the Capital and Zealand Regions of Denmark. The study population is extracted from a dataset retrieved from the Electronic Health Record (EHR) system 'Sundhedsplatformen' (Epic Systems Corporation, WI, USA) from 1 January 2017 to 31 December 2024, including granular data from approximately 1.1 million anesthetic procedures

Time perspective

Retrospective

Treatments tested in this trial

  • Time in minutes from admission to closed reduction

    Other intervention

    Time in minutes from admission to closed reduction measured as: From arriving time in the emergency department until the start of surgery in the operating theater.

Treatment groups

3,700 Participants
are divided into 1 treatment group
Group A: patients underwent closed reduction of dislocated THA1 intervention
