A concept map care plan is a diagram that organizes a patient's problems, supporting data, interventions, and evaluations to provide a holistic view of the patient's situation. It involves 5 steps: 1) developing a basic diagram of the patient's reason for admission and problems, 2) analyzing and categorizing collected data, 3) identifying goals and interventions for each diagnosis, 4) evaluating the effectiveness of the plan and whether goals were achieved, and 5) linking related diagnoses to show their impacts on one another. The overall purpose is to organize patient information to effectively plan and provide nursing care.
