Scoping review on CAT-based measurement

Knowing patients’ function and health-related quality of life (HRQoL) is pivotal in order to deliver true patientcentred healthcare (1–3). HRQoL can be defined as ‘‘how well a person functions in their life and his or her perceivedwell-being in physical, mental, and social domains of health’’ (4). Functioning refers to an individual’s ability to carryout some pre-defined activities, while well-being refers to an individual’s subjective feelings (4). However, due toits subjective nature, HRQoL is often inaccurately assessed by health care providers (HCPs) or poorly captured bymedical tests and procedures (5–8). As such, patient involvement is now perceived as essential to HRQoLassessment. Patient-reported outcomes (PROs) are defined as “a measurement based on a report that comesdirectly from the patient about the status of a patient’s health condition, without amendment or interpretation ofthe patient’s response by a clinician or anyone else” (9). Patient-reported outcome measures (PROMs) refer to thetools used to measure PROs and are now preferred tools for the assessment of HRQoL in cancer care (10–18).
