Brief Summary

This is a prospective study-registry on preoperative patient characteristics and postoperative complications in patients having fast-track hip and knee replacement surgery in 8 Danish dedicated arthroplasty departments from all five health regions in Denmark. The registry consists of detailed patient and physician reported preoperative characteristics and including prescribed medication and lab results. Follow-up is based on electronical medical records by dedicated nurses with physician backup and includes Clavien-Dindo and Comprehensive Complication Index scoring. All patients having day-surgery also completes a patient reported questionaire on health-care utilization and return to work by day 30. Finally, a machine-learning algorithm for identification of "high-risk" patients based on he preoperative data is included.

Study Arms (3)

Day-surgery group

Patients having hip or knee replacement as day-surgery with successful discharge to own home on day of surgery

Procedure: Day-surgery

High-risk patients

Patients evaluated to be at increased risk of postoperative complications. These patients will receive relevant additional attention based on type of comorbidity. I.e. preoperative evaluation of iron status and i.v. iron treatment in case of preoperative anaemia, increased focus on avoidance of NSAIDs and adequate fluid therapy in patients with renal disease etc.

Procedure: High-risk patient

Main group

Patients who are not scheduled for day-surgery and without comorbidities qualifying as "high-risk". These patients go through a standard fast-track procedure with discharge to own home when fulfilling functional discharge criteria.

Procedure: Main Group

Interventions

Day-surgeryPROCEDURE

Standard surgical procedure but with planned discharge on day of surgery

Day-surgery group

Standard fast-track procedure but with additional perioperative measures dependent on risk-profile.

High-risk patients
Main GroupPROCEDURE

Standard fast-track procedure according to usual standard of care and discharge when fulfilling functional discharge criteria

Main group

Eligibility Criteria

Age18 Years+
Sexall
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The participating dedicated arthroplasty departments are placed in either large university or regional hospitals. The departments cover all five healthcare regions in Denmark and are estimated to contribute with about 40% of the annual hip and knee replacements in Denmark. Thus, the population is representative of the general Danish arthroplasty population.

You may qualify if:

  • age \>18 years
  • non-malignant surgery
  • danish social security number
  • elective procedure

You may not qualify if:

  • unwilling to provide informed consent
