Successful management of native Joint septic arthritis (SA) hinges on the timely initiation of appropriate antibiotic therapy coupled with thorough joint debridement. Since 2018 we have implemented a protocol for empirical antibiotic in patients with suspected SA recommending amoxicillin/clavulanate (and cotrimoxazole in cases of beta-lactams allergy) based on local flora. Nevertheless we have recently found that institutional compliance to the protocol is only about 50% and many physicians are still choosing alternative wider spectrum regimens. The aim of this study is to assess whether current clinical and epidemiological characteristics of patients treated for this condition justify an update or whether previous recommendations are still valid. All adult patients admitted to our institution with suspected SA between 2018-2022 were retrospectively reviewed. Data was collected from electronic medical records and then compared to similar data previously collected concerning the 2009-2017 period (that served as a basis for the aforementioned protocol).Aim
Method
Determine therapeutic and prognostic value of three different prosthetic joint infections (PJI) staging systems – JS-Bach, McPherson and PJI-TNM. Retrospective analysis of patients who received surgery for PJI between 2011 and 2022 at one single institution, including DAIR, 1-stage revision and 2-stage revision. We applied three staging systems - JS-Bach, McPherson, PJI-TNM – and categorize the results into A (less severe), B (intermediate) and C (most severe). Demographic data and comorbidities, anatomic location, type of treatment, recurrency of infection, final outcome and antibiogram were analyzed.Aim

Infection is a complication in hip arthroplasty. It increases mortality and morbidity and is a cause for patient's dissatisfaction. Previous Works report an infection rate between 0,4% e 1,5% in primary hip replacement and between 3,2% in revision hip replacement. The aim of this work was to access the infection rates in one hospital, compare them with the reported rates and investigate possible risk factors for infection. Electronic clinical records were consulted. Patients who underwent total hip arthroplasty (primary or revision) or hemiarthroplasty in one hospital, between the 1st February 2011 and 31st February 2013, were included. Two hundred and sixty one patients (267 surgeries) were included. Demographically, 57,5% were female patients and 42,5% were male patients with an average age of 77,1 years (± 12,3 years). Infection rate for hemiarthroplasty 3,1%, for primary total hip arthroplasty was 1,4% and for revision procedures 4,8%. A statistically significant relation was found between arthroplasty infection and superficial wound infection (p<0,001), wound dehiscence (p<0,001), and surgery performed during summer months (p<0,05) No relation was found with duration of the surgery or the hospital stay or the patient's comorbidities. The infection rate is similar to the rate reported in other clinical centres. Superficial wound complications are a good predictor for arthroplasty infection, so it is important to diagnose and start prompt appropriate management and vigilance. The increase in infection rates in summer months may be related to higher operating room temperature or less routined personal. We concluded, therefore, that infection is a complication in hip arthroplasty being prevention is a key feature when arthroplasty is performed, as well as clinical vigilance for infection signs.
