Brief Summary
Aim: To compare the effect of one single dose versus multiple doses of prophylactic antibiotics administered within 24 hours, on the development of PJI in patients with osteoarthritis undergoing primary THA. The study is designed as a cross-over, cluster randomized, non-inferiority trial. All Danish orthopedic surgery departments performing primary THA with the majority being within inclusion criteria will be involved: Based on national quality databases, two-year cohorts of approximately 20,000 primary THAs conducted at all public and private orthopedic departments in Denmark, this includes 36 sites corresponding to a total of 39 departments.

Outcome Measures
Primary Outcomes (1)
Incidence of Prosthetic joint infections (PJI)
The definition of PJI is based on revision surgery. Revision surgery is defined as a new surgical intervention the first time after the primary intervention including debridement alone or in combination with complete or partial removal or exchange of the implant. 1. Two or more intraoperative deep-tissue samples of phenotypically indistinguishable bacteria isolated from at least 3 deep-tissue samples 2. One or more positive intraoperative samples from a closed fluid aspirate AND a biopsy (fluid AND tissue) of phenotypically indistinguishable bacteria isolated 3. A PJI when an indication of deep infection is reported to The Danish Hip Arthroplasty Registry (DHR) by the surgeon upon revision surgery
Within 90 days from index surgery
Secondary Outcomes (9)
Number of patients with one or more Serious Adverse Events (SAEs)
Within 90 days from index surgery
Incidence of Potential PJI referred to as PJI-likely
Within 90 days from index surgery
Length of hospital stay (LOS)
Within 90 days from index surgery
Incidence of Major Adverse Cardiovascular Events (MACE)
Within 90 days from index surgery
Hospital-treated infections (excluding Surgical Site infections)
Within 90 days from index surgery
- +4 more secondary outcomes
Other Outcomes (4)
Incremental cost-effectiveness
Within 90 days from index surgery
Rate of revision after THA
Within 1 year from index surgery
Mortality rate after index surgery
Within 1 year from index surgery
- +1 more other outcomes
Study Arms (2)
Treatment A, Single-dose practice
EXPERIMENTALOne preoperative single dose of either Dicloxacillin/Cloxacillin 2g OR Cefuroxime 1.5g administered intravenously prior to surgical incision. As the study is a non-inferiority trial, we have chosen the Experimental design category.
Treatment B, Multiple-dose practice
ACTIVE COMPARATOROne preoperative dose of either Dicloxacillin/Cloxacillin 2g OR Cefuroxime 1.5g administered intravenously prior to surgical incision followed by 3 postoperative doses of Dicloxacillin/Cloxacillin 1g x 3 OR Cefuroxime 750mg x 3 within 24 hours after the preoperative dose.
Interventions
Patient inclusion starts day one, cross-over of departments from treatment A (single-dose) to B (multiple-dose) or vice versa after one year and end of inclusion happens after 2 years. All centers in Denmark use either Cloxacillin/Dicloxacillin, Cefuroxime or both drugs as standard prophylactic antibiotic practice for THA. In cases of cephalosporin allergy or general beta lactam allergy, the antibiotic clindamycin may be administered. In this trial, patients will be administered the standard prophylactic antibiotic practice of either single-dose (A) or multiple-doses (B) of antibiotics administered at each respective cluster that respective year. Both practices of dose administration for antibiotic prophylaxis (i.e. single- or multiple-dose) follow current standards of treatment and are based on present clinical practice guidelines.
Eligibility Criteria
You may qualify if:
- \. All patients receiving a primary Total Hip Arthroplasty (THA) due to primary and secondary causes of osteoarthritis
You may not qualify if:
- Patients receiving a primary THA due to either acute or sequelae of proximal femoral or acetabular fractures
- Patients receiving a primary THA due to bone tumor or metastasis
