Assessment of Quality-of-Life Outcomes

Testa, Marcia A., Simonson, Donald C.·1996·New England Journal of Medicine

Abstract

Since 1948, when the World Health Organization defined health as being not only the absence of disease and infirmity but also the presence of physical, mental, and social well-being,1 quality-of-life issues have become steadily more important in health care practice and research. There has been a nearly exponential increase in the use of quality-of-life evaluation as a technique of clinical research since 1973, when only 5 articles listed “quality of life” as a reference key word in the MEDLINE data base; during the subsequent five-year periods, there were 195, 273, 490, and 1252 such articles. The growing fields of outcomes . . .

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
