[Protocols and procedures]. / Protocolli e procedure.

Evidence-based nursing increases behavior uniformity during everyday activities and in critical or complex situations. A recorded and programmed activity, the foreseeing of resources, the checking of application modalities and outcome evolution, and warning of complications, are the basis for a good pre-ordered flow chart. Nurses themselves build valuable protocols for every care procedure. This study describes central venous catheter (CVC) care as an example of a useful procedure.
