[Translated article] Risk factors associated with periprosthetic infection in patients with femoral neck fracture: A case-control study.

BACKGROUND: Infection is one of the most important local complications in the patient with femoral neck fracture treated with arthroplasty. The aim of the present study is to describe and analyze possible risk factors that could be involved in periprosthetic infection in the patient with femoral neck fracture. METHODS: A retrospective case-control study was performed including patients with femoral neck fractures treated with arthroplasty in the period between January 2015 and December 2017. Cases were defined as patients with femoral neck fracture who after undergoing arthroplasty (hemiarthroplasty or total hip arthroplasty) had a periprosthetic infection, whose diagnosis was carried out according to the major and minor criteria described in the International Consensus on Musculoskeletal Infections (Philadelphia 2018). In order to mitigate the influence of variables that could be considered confounding variables, a multivariate analysis was carried out. OUTCOMES: A statistically significant association was found between periprosthetic infection and certain variables present at the time of admission, including the presence of moderate or severe anaemia (OR: 10.91; 95% CI: 1.07-111.50; P = .007), thrombocytopenia (OR: 27.72;95% CI: 3.48-221.01; P = .002), history of thromboembolism event (OR: 8.80; 95% CI: 1.31-59.38; P = .026), anxious-depressive disorder in treatment with two or three drugs (OR: 21.36; 95% CI: 3.65-125.12; P = .001) and liver disease (OR: 32.04; 95% CI: 2.59-396.29; P = .007). CONCLUSIONS: Periprosthetic infection in the patient with femoral neck fracture treated with arthroplasty could be related to the presence of certain variables at the time of hospital admission, including moderate or severe anaemia, thrombocytopenia, history of thromboembolic event, anxious-depressive disorder in treatment with two or three drugs or liver disease.

[Influence of medical outliers in patients with femoral neck fracture]. / Influencia del ingreso hospitalario ectópico en pacientes con fractura del cuello femoral.

OBJECTIVES: The objective is to describe and analyze how outlier admission influences hospital stay and the appearance of complications in patients with a femoral neck fracture treated with arthroplasty. MATERIAL AND METHOD: A historical cohort study was carried out in which the group of patients with a displaced fracture of the femoral neck who had an outlier admission was defined as an exposed cohort, that is, they were admitted to a hospitalization area not belonging to the Orthopedic Surgery and Traumatology department, unlike the unexposed cohort, that included patients admitted to a hospitalization area assigned to the Orthopedic Surgery and Traumatology department. RESULTS: Outlier admission was a risk factor for requiring a postoperative transfusion (RR 1.52, 95% CI 1.05-2.21; P=.035), to have a postoperative stay longer than 5 days (RR 1.35, 95% CI 1.04-1.74; P=.038) and to suffer general postoperative complications (RR 1.35, 95% CI 1.02-1.78; P=.048). CONCLUSIONS: Outlier admission is a threat to the quality and safety of health care. In patients over 80 years of age, medical outliers is a risk factor for postoperative transfusion and systemic postoperative complications.

Result of the implementation of telematic consultations in orthopaedic surgery and traumatology during COVID-19 laparoscopic surgery. / Resultado de la implantación de consultas telemáticas en cirugía ortopédica y traumatología durante la pandemia COVID-19.

The COVID pandemic has made telematic consultations a basic tool in daily practice. AIMS: The main objective of the study is to assess the results of the application of telematic consultations to limit the mobility of patients. The operational objectives are; to propose a consultation plan, to know how attendance limits consultations and to define which pathologies benefit the most from this plan. METHODS: A scheme is proposed with the creation of pre-scheduled clinic to assess suitability and the possibility of carrying them out in a single non face-to-face act. RESULTS: Phone call to 5,619 patients were made with a lack of response of 19%. The cases of 74% of the patients that answered were resolved virtually. There is a difference between units, obtaining a higher answering rate from patients appointed to specific clinic units, OR = 0.60, or to general trauma ones, OR = 0.67. The lowest answering rate was obtained from those derived from the emergency department. Twenty per cent of the consultations were not accompanied by complementary tests that would have favored the resolution in a single act. The general trauma consultations, OR = 0.34, postoperative control, OR = 0.49, and specific unit ones, OR = 0.40, were the ones that better met this requirement. Out of the remaining patients, the general trauma consultations, OR = 0.50, and those referred to units, OR = 0.54, were the ones that had a higher resolution rate without in- person consultation. CONCLUSIONS: The cases of 74% of the patients who answered the phone call were resolved virtually. Cases of 20% of the patients cannot be solved in a single act because they are derived without complementary tests. Osteosynthesis and postoperative arthroscopic follow-up consultations are the ones that need to be carried out in person the most.
