(1) Background: Emergency and intensive care nurses are among the health professionals most exposed to occupational health issues such as stress and burnout, etc. Coaching has been considered a useful preventative strategy to provide better support for professionals. This study has two objectives: the first objective is to identify the coaching needs of emergency and intensive care nurses, and the second is to propose a coaching model that addresses the needs and helps manage occupational health issues. (2) Methods: this study followed a mixed-method design, and it included thirty nurses working in the emergency and intensive care unit from two public hospitals in Morocco. The study entailed semi-structured interviews transcribed verbatim until data saturation, guided by the grounded theory approach in order to explore the coaching requirements of emergency and intensive care nurses, and the measurement of the three dimensions of burnout with the Maslach Burnout Inventory (MBI). (3) Results: the results reveal three main conceptualizing explanatory categories of the nurses' coaching requirements: Steps of a coaching action; topics for a coaching action related to occupational health issues such as stress and burnout (it is shown that the prevalence of burnout in our sample is 66.7%); barriers to a coaching action. (4) Conclusions: by investigating the coaching requirements of the nursing staff, a transtheoretical coaching model with a theoretical and ethical basis was suggested in this regard for their occupational health issues management.
