EQ-5D Clause Samples

EQ-5D. The EQ-5D is a standardized instrument used to measure health outcomes over time (EuroQOL Group, 2009). For example, the instrument could be administered to patients before an intervention, and then at some (or several) point(s) after the intervention. The instrument uses five items to measure the following five domains: 1) mobility; 2) self-care; 3) usual activities; 4) pain/discomfort; 5) anxiety/depression. For each of the five items, patients are asked to select the response that best describes their health on the day the instrument is administered. Responses range from no problems to extreme problems. Patients are then asked to rate their overall health on a scale from 1-100. This instrument is quick to administer and is specifically designed to measure perceived health over time. However, the domains are extremely limited and individualistic in scope and may not capture aspects considered important to quality of life in all populations. Additionally, patients in some settings may be unfamiliar with the 1-100 scale format, and patients with similar clinical pictures may have vastly different perceptions about the degree of difficulty they have in a given domain.
