The COVID-19 pandemic requires a change in our clinical practice, through the adoption of new strategies that allow comprehensive care for our patients, guaranteeing the safety of both patients and healthcare professionals. Our objective was to develop practical recommendations, agreed among a panel of experts, on the use and safety of rheumatological ultrasound during the COVID-19 pandemic. We performed a narrative review of the available literature. Based on the literature review, we produced preliminary recommendations that were subsequently agreed among a panel of experts using the Delphi methodology with a 1-5 Likert scale. Agreement for each recommendation was considered if 75% of the panel members scored the item ≥4 on the Likert scale. 5 overarching principles and 28 recommendations were issued and agreed among the panel. Group consensus was achieved in 100% of items. The document provides useful information about preventive measures in the practice of ultrasound in rheumatology in times of a COVID-19 pandemic based on the experience and literature available to date.enECOSEREcografíaGrupo ECOSERPosicionamientoPositioningSafety COVID-19Seguridad COVID-19Sociedad Española de Reumatología –SER–Spanish Society of Rheumatology –SER–COVID-19DisinfectionEquipment ContaminationGelsHumansInfection ControlInfectious Disease Transmission, Patient-to-ProfessionalInfectious Disease Transmission, Professional-to-PatientMicroscopic AngioscopyOilsPandemicsPersonal Protective EquipmentRheumatic DiseasesRheumatologySARS-CoV-2Ultrasonographyresearch article33376052open access10.1016/j.reuma.2020.10.0102173-5743PMC7983453https://doi.org/10.1016/j.reuma.2020.10.010https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7983453/pdf
