Background: Information that awfully significantly changes the patient's life is referred to as "bad news." Breaking bad news requires skillful communication and is by no means simple. For most nurses, breaking bad news is a handicap caused by inadequate training. When delivering bad news, the six-step SPIKE procedure is frequently employed. Aim of the study: The study's objective was to evaluate how the "SPIKE" protocol affected critical care nurses' attitudes, practices, and feelings for breaking bad news. Materials and Method: Research Design: For this study, a quasi-experimental research design was adopted. Setting: This study was conducted at the 16-bed general adult intensive care unit (ICU) of Al-Rahmaneah Central Hospital, which is divided between Hall A and Hall B.
