Keynote webinar | Spotlight on sleep in brain health

LIVE: Thursday 2nd May 2024, 18:00-19:30 (CEST)

Quality sleep is essential for health. But what happens to our brains when sleep patterns are disturbed? Join our experts to explore the interplay between sleep disruption and neurological diseases, and the questions that you need to be asking your patients to help you prevent the harmful effects of sleep deprivation.

Abstract

Background

To validate and evaluate the reliability of the Dutch version of the Chronic Ear Survey (CES) in patients suffering from Chronic Suppurative Otitis Media (CSOM) and to evaluate clinical outcomes of surgery using this questionnaire.

Methods

We developed the Dutch version of the CES (D-CES) using forward-backward translation of the original CES into the Dutch language. Next, patients with CSOM and controls completed the D-CES pre- and postoperatively. Internal consistency, test-retest reliability, known-group validity and convergent validity were evaluated. In addition to the D-CES, the Short Form 36 (SF-36) was administered to all participants to correlate D-CES data to quality of life.

Results

A total of 29 patients with CSOM scheduled for ear surgery were included. Our control group consisted of 26 patients scheduled for eye surgery, all without signs and symptoms of CSOM. Cronbachs’ α of the complete questionnaire was 0.69. The Intraclass Correlation Coefficients (ICCs), reflecting test-retest reliability, ranged between 0.69 and 0.82. Scores differed significantly between CSOM patients and controls with substantial lower (more impaired) D-CES scores in the CSOM group. Duration of complaints preoperatively and the presence of a dry ear and/or improvement of hearing postoperatively all had a significant impact on D-CES improvement scores. Small to moderate correlations were found between D-CES subscales and matching subscales of the SF-36.

Conclusion

The D-CES is an appropriate disease specific questionnaire to assess a patient’s perceived functional health in CSOM.
