Arthroplasty, Replacement, Hip, Closed Reduction, Length of Stay
Conditions
Brief summary
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.
Interventions
OTHERTime in minutes from admission to closed reduction
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.

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.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Post procedure length of stay | 30 days after the closed reduction | Post procedure length of stay from closed reduction until discharge from the hospital (hours) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Admissions to Intensive care unit | 30 days after the closed reduction | Admissions to the intensive care unit within 30 days after the closed reduction. |
| Readmission | 30 days after discharge | Readmission within 30 days after discharge |
| Delirium during admission | From admission to discharge up to 30 days after closed reduction | Defined as diagnose of delirium (F05.x, obtained from the diagnosis codes from the given admission) or the non-planned administration of haloperidol, olanzapine, risperidone, or quetiapine (as a surrogate for new onset delirium) |
| All-cause mortality | 90 days after closed reduction | 90 days all-cause mortality (Y/N) |
| Infection requiring hospital contact | Post procedure until 30 days after discharge | Defined as diagnosed infection (postoperative infection (T81.4), pneumonia (J13.x-J18.x), Cystitis (N30.x, N39.0), sepsis (R65.x A40.x, A41.x), C. difficile (A04.7) obtained from the diagnose codes from the given admission) or administration of antibiotic treatment (as a surrogate for in-hospital infection |
| Cardiovascular complications | From admission to 30 days after discharge. | Defined as diagnosed arrythmia (I47.x, I48.x, I49.x), myocardial infarction (I21.x, I22.x), cerebral ischemia (I61.x, I63.x, I64.x), hemorrhage(T81), pulmonary embolism(I26.x) or deep venous thrombosis(I80.2) (obtained from the diagnosis codes from the given admission) |
| Acute kidney failure | Post procedure until 30 days after discharge | Defined as serum creatinine increase of more than 25 μmol/L within a period of less than 48 hours. (As a surrogate for acute kidney failure) |
