Understanding and making us understand is intrinsic and present at all times in our lives. It is part of the human being to be fallible, this art of communicating can, of course, suffer failures that can have various reasons and consequences (Santos et al, 2010). This project intends to build and validate an assessment instrument which identifies the nurses' perception of communication failures during the shift handover, as well as the strategies that can be used to reduce these failures. Thus, will be possible to redesign measures and reorient services and structures so that practices can be patient-centered. With communication being one of the pillars of the nursing profession, it must be valued and operate as the invigorating element for care delivery (Santos et al, 2010).
