The purpose of this study is to determine the reliability and concurrent validity of the figure-of-eight method of measuring hand edema in the burn patient population. Establishing the reliability and validity would enable a more time efficient assessment than the currently accepted methods.
Condition or disease
Procedure: figure-of-eight hand measurementsProcedure: water volumetry hand measurements
A prospective study involving 33 burn patients admitted to the US Army Burn Center. Two raters will perform three separate blinded measurements for hand edema using the figure-of-eight measurement technique. A third rater will then perform two blinded measurements using water volumetry. All measurements will be read and recorded by an independent recorder. The three measurements of rater 1 and 2 will be analyzed to determine intratester reliability. The average of the three figure-of-eight measurements will be compared to measure intertester reliability. The two volumetry measurements will be compared to determine intratester reliability. The average of the 2 volumetry measurements and the average fo the three figure-of-eight measurements will be used to determine concurrent validity.
