To investigate the incidence and time-trend in reoperation due to deep Surgical Site Infection (SSI) following hip fracture surgery. This was a population-based, nationwide, cohort study. We included 74,771 from the Danish Multidisciplinary Hip Fractures Register (1) consisting of patients 65 years of age or older, who underwent surgery between January 1st 2005 and December 31st 2016 for all types of hip fracture. Cross-linkage with the Danish National Patient Register and The Danish Civil Registration system was made. Demographic data extracted included vital status, civil status, gender, age, Body Mass Index (BMI), fracture classification (AO/OTA 31A-C) and surgical procedures binary registered as joint replacement or internal fixation, Charlson comorbidity index (CCI) and secondary diseases not included in CCI. Outcome was reoperations due to deep SSI in accordance with the definition from Centre for Disease Control (2). We computed cumulative incidence rates and risk ratios (RR) by calendar year periods and by different risk factors, considering death as competing risk and adjusting for age, gender, CCI, fracture type and surgery type.Aim

Previous publications have suggested that the incidence of revisions due to infection after THA is increasing. We performed updated time-trend analyses of risk and timing of revision due to infection after primary THAs in the Nordic countries during the period 2004–2018. 569,463 primary THAs reported to the Nordic Arthroplasty Register Association from 2004 through 2018 were studied. We estimated adjusted hazard ratios (aHR) with 95% confidence interval by Cox regression with the first revision due to infection after primary THA as endpoint. The risk of revision was investigated. In addition, we explored changes in the time span from primary THA to revision due to infection.Aim

To study whether revision for prosthetic joint infection (PJI) after early PJI in primary Total Hip Arthroplasty (THA) is associated with a high mortality, when compared with: Patients, who did not undergo revision for any reason and Patients who underwent an aseptic revision. This population-based cohort study was based on the Danish Hip Arthroplasty Register on primary THA performed in Denmark from 2005 to 2014. Data from the Danish Hip Arthroplasty Register were linked to microbiology databases, the National Register of Patients, and the Civil Registration System to obtain data on microbiology, comorbidity, and vital status on all patients. The mortality risk for the patients who underwent revision for PJI within 1 year from implantation of primary THA was compared with (1) the mortality risk for patients who did not undergo revision for any reason within 1 year of primary THA; and (2) the mortality risk for patients who underwent an aseptic revision.Aim
