Would Roy's Adaptation Model work in the A&E department? Problems associated with the application of the model in this area include the length of time needed for assessment; the paucity of testing the application of models in A&E so far; the difficulty of introducing a new language to nurses; the focus of assessment detracting from the physiological problems; the difficulty in involving the patients in decision-making; and the lack of information about what should be done if the patient is unable to participate in his care.
