Two multicentre works with participation of professionals from two research groups of http://bit.ly/1WR70M1" Vall d'Hebron Research Institute (VHIR) have been recognized as the best oral communications at the 65th Congress of the Spanish Association of Paediatrics (AEP) and at the 11th Congress of the Spanish Society of Paediatric Orthopaedics (SEOP). In the case of the work presented to the Congress of the AEP, it was attended by Dr. Susana Melendo, researcher at the http://bit.ly/2sxviFr Infection in Immunosuppressed Paediatric Patient research group and physician at the http://bit.ly/1PKAMQk" Infectious Pathology and Paediatrics Immunodeficiencies Unit (UPIIP) of Vall d'Hebron.In the SEOP participated Dr. César Galo García Fontecha, head of the research group in http://bit.ly/2tB5O9V Reconstructive Surgery of the Locomotor System and physician at the http://bit.ly/1e4M3N4 Infant Orthopaedic Surgery Unit of Vall d'Hebron. Normal1 The two communications analyse the application and impact of the protocol developed by the Spanish Society of Paediatric Infectious Diseases (SEIP), the Spanish Society of Paediatric Rheumatology (SERPE) and the SEOP to diagnose and treat bone and joint infection in paediatric patients. To do this, the data provided by 37 hospitals that are part of the Network for Paediatric Bone and Joint Infections (RIOPed) have been analysed. RIOPed, created in 2014, counts with Vall d'Hebron as member. Normal1 For the authors, "the recognition of the quality of work in these two national conferences shows that multicentre projects involving multidisciplinary collaboration provide good results in clinical research and our centre is a good example". Normal1 Osteomyelitis Normal1 Musculoskeletal infections are relatively frequent illnesses in childhood tha can affect the growth plate or the bone epiphysis and cause alterations in the development of bone and/or joint. The early and correct diagnosis and appropriate antibiotic treatment are the basis for healing, but only in 40% of cases the microorganism responsible is identified, forcing to make an empirical treatment and not the ideal one, led by antibiogram. For this reason, the three companies in 2014 published a consensus document in Paediatric Annals, which collected all the scientific evidence published on the bone and joint infection not complicated. Normal1 The same year it was created the Network for Paediatric Bone and Joint Infections (RIOPed) as a national network for multidisciplinary research into this disease. It is comprised of 37 centres, among which is the Vall d'Hebron University Hospital. Normal1 Analyse the impact of the protocol Normal1 The two winning entries collected information obtained through the RIOPed network between the months of September 2015 and September 2016. Thanks to these data it has been able to assess the real impact of national consensus to establish clinical practice and adherence to its recommendations. Normal1 In fact, the findings show a significant improvement in the use of imaging tests that do not produce ionizing radiation to make the diagnosis. There has also been an improvement in the tests of identification of the germ that causes infection (blood cultures, cultures of synovial fluid and bacterial PCR in synovial fluid). At the same time, there is a decrease in the time for intravenous antibiotics treatment, with a shorter hospital stay.
