With the IEQ–MP, you can accurately assess the effects that an illness and treatment are having on a patient’s life. The tool’s strength lies in its ability to improve communication among patients, families, and healthcare providers using four separate questionnaires to assess a patient’s medical experience from multiple perspectives.
