Popis: OBJECTIVE This study aims to assess and compare the reliability of the Holgers, the IPS, and the Tullamore scales for skin tolerability assessment of postoperative bone-anchored hearing implant images. STUDY DESIGN A survey study and retrospective review of percutaneous osseointegrated auditory implant images for scoring using three skin classification scales. SETTING McGill University Health Center, Montreal, Quebec, Canada. PARTICIPANTS Healthcare workers experienced and inexperienced with osseointegrated auditory implant skin classification scales. MAIN OUTCOME MEASURES Participation involved completing: 1) survey questionnaires assessing experience with osseointegrated auditory implants and related skin reactions and 2) scoring postoperative osseointegrated auditory implant with surrounding skin images using the Holgers Classification, the IS (of the IPS) scale, and the Tullamore Classification. Participants were asked to rate 12 images of postoperative osseointegrated auditory implant and surrounding soft tissue. This process was repeated until participants scored all images using the three scales; each rater graded 36 images in total. The order in which scales were presented occurred at random. Intraclass correlation coefficients were calculated to assess reliability. RESULTS Thirty-one participants were recruited to the study. Fourteen (45.2%) had experience with at least 1 osseointegrated auditory implant skin classification scale, while 17 (54.8%) did not have experience. The wide and overlapping 95% confidence intervals of the intraclass correlation coefficients results do not provide us with enough evidence to define a well-established degree and hierarchy of reliability when comparing the scales. Among experienced raters, all scales presented moderate to good reliability. CONCLUSIONS The Holgers Classification, the IPS scale, and the Tullamore Classification all present moderate to good reliability when used by experienced raters to assess skin reactions following surgical implantation of an osseointegrated hearing device. As a result, clinicians should use these scales with a degree of caution. The findings of this study do not provide us with enough evidence to single out one of the scales as a standard to follow, but more extensive studies are required to assess the reliability of the scales.
