The primary application of chronic suppurative otitis media outcome survey / 重庆医学

ABSTRACT

Objective To analyze the quality of life among adults with chronic suppurative otitis media,and to research the chan-ges of the life quality between preoperative and postoperative.Methods We modified the chronic ear survey(CES)through inter-view adults with chronic suppurative otitis media.The modified scale (Chronic Suppurative Otitis Media Outcome Survey)was ad-ministered to 110 patients in a prospective manner,and then was validated according to established criteria for reliability and validi-ty.Then we assessed the outcomes of surgeries for chronic suppurative otitis media.Results The chronic suppurative otitis media outcome survey includes 17 entries,and was divide into four dimensions.Excellent test-retest reliability was obtained for the survey score (R=0.967).Cronbach′s α correlation coefficient were calculated as 0.864 for the total survey.Criterion validity showed a high correlation between scores on chronic suppurative otitis media outcome survey and scores on CES (R=0.977,P <0.01).U-sing principal components extraction with orthogonal rotation,it was performed on the composite data set,and this yielded a four-factor solution that explained 70.394% of the variance.The average score of patients before surgery was 51.660±10.762,post-op-erative scores was 75.893 ± 7.734.The total score wasn′t significantly changed after the surgery,and the average value was 24.23±7.67 (t=24.653,P <0.01).Conclusion The chronic suppurative otitis media outcome survey is a reliable and valid meas-ure of quality of life for adults with chronic suppurative otitis media,and it is more suitable than the CES in outcomes studies and clinical trials.
