Objective: to identify disinfection methods for intravenous catheter hubs and needleless connectors in hospitalized patients, as well as to verify the effectiveness of the interventions to prevent bloodstream infections associated with intravenous catheters. Method: a scoping review following the Joanna Briggs Institute recommendations. The search was conducted in the following electronic databases: PubMed, Embase, Cochrane Library, Literatura Latino-Americana e do Caribe em Ciências da Saúde, Base de Dados Enfermagem and Bibliografía Nacional en Ciencias de la Salud Argentina, as well as in studies indicated by experts. The search was conducted until September 2020. The review protocol was registered in the Open Science Framework. Results: a total of 27 studies were included, of which five were Guidelines and 22 were articles published in journals. There is a significant variety of disinfection methods for hubs and connectors. Chlorhexidine Gluconate, Isopropanol and Povidone-iodine were indicated for active disinfection; and Chlorhexidine Gluconate and Isopropanol, for passive disinfection. The disinfectant volume varied from 0.25 mL to 0.6 mL. Friction time in active disinfection ranged from five to 30 seconds, and contact time in passive disinfection varied from three minutes to seven days. The disinfectants' drying time was over five minutes. Conclusion: a variety of disinfection methods is verified, although with no consensus on the best indication. Studies that show the amount of disinfectant, pressure, friction and drying time are required. There is a need to conduct research studies with disinfection practices used in Brazil and randomized clinical trials.
