The Kidney, Liver, Index surgery and C reactive protein score is a predictor of treatment response in acute prosthetic joint infection.

PURPOSE: This work seeks to verify the utility of the KLIC score as a predictor of treatment success or failure in patients with knee and hip acute prosthetic joint infections (APJI). These patients were treated in our centre, which is not a prosthetic joint infection reference centre. The KLIC score assesses factors such as chronic kidney failure (2 points) (Kidney), liver disease (1.5 points) (Liver), revision surgery or femoral neck fracture (1.5 points)and cemented prosthesis (2 points) (Index surgery) and a C-reactive protein level (CRP) greater than 11.5 mg/dL (2.5 points), as a predictor of treatment success or failure in patients with knee and hip acute prosthetic joint infections (APJI). METHODS: We retrospectively reviewed 30 patients with APJI who were treated using debridement, antibiotics, irrigation and retention (DAIR) treatment between January 2007 and December 2016. Patients' KLIC scores were calculated. The main outcome was success or failure of DAIR treatment of APJI. RESULTS: DAIR treatment succeeded in 21 cases and failed in nine cases. Differences in outcome were found according to the KLIC score. For KLIC scores >2 and ≤4, there were three successes and zero failures; for scores 4-5, there were nine successes and two failures; for scores >5 and ≤7,there were nine successes and four failures; and for scores >7, there were zero successes and three failures (p = 0.025). We found a positive predictive value and negative predictive value of 33% and 100% for scores ≤4 (score for calculations: 3.5), 43% and 84% for scores 4-5 (4.5), 50% and 68% for scores >5 and ≤7 (5.5), and 100% and 76% for scores >7 (7.5), respectively. The area under the ROC curve was 0.762 (95% confidence interval, 0.569-0.955). CONCLUSIONS: The KLIC score was useful in predicting success or failure of DAIR treatment of APJI. This supports the conclusion that with a score < 3.5, treatment is likely to succeed and with a score of >6, it is likely to fail.

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.
