Quality of life after spinal cord injury: a literature critique and meta-analysis (1983-1992).

Research articles cross-indexed in Index Medicus under the subject headings "quality of life" (QOL) and "spinal cord injury" (SCI) were examined in order to compare their relative merits in terms of research design, sampling techniques and the type of QOL criteria included. Of 3,710 citations indexed for the ten year period 1983 through 1992 under "quality of life," thirty-two research articles (< 1 percent) were cross-indexed with the subject heading "spinal cord injury." The modal design was a descriptive survey or case study (n = 23 or 72 percent). None of them were randomized clinical trials. Because of limited rigor of research design and poor validity of measurements, conclusions about the ability of rehabilitative care to improve the QOL for SCI persons could not be drawn from the studies reviewed. Meta-analysis indicated that severity of injury is associated with QOL, with more severe injury being correlated with poorer quality. The critique concludes that QOL research with SCI persons needs to be better designed and should include more uniform and valid criteria.
