Psychometric testing of the NEECHAM Confusion Scale among patients with hip fracture

The main aim of this study was to assess the reliability and validity of a Swedish translation of the NEECHAM Confusion Scale among 73 patients having surgery for hip fractures. Cronbach's alpha before and 7 days after surgery were.73 and.82, respectively. Principal-component analyses yielded three factors explaining 69% of the variance of the variables preoperatively and 73.6% of the variance 7 days postoperatively. Four months after discharge vital function, factor II in the NEECHAM scale, significantly predicted the total score on the Ferrans and Powers Quality of Life Index. Items reflecting information processing, behavior, and urinary continence, factor I, also predicted functional capacity, using the Standardized Practical Equipment test, a tool measuring instrumental daily activity. The scale seems to be a reliable and valid instrument for evaluating acute confusional state among patients with hip fracture.
