Аннотация:To evaluate the appropriateness of screening as a preventive health tool, it is necessary to estimate its validity (or accuracy) and reliability (or reproducibility). Accuracy is determined by measures of sensitivity, specificity, and positive predictive value, whereas reliability reflects the consistency of results when the test is performed more than once on the same person under the same conditions. l The accuracy and reliability of skin cancer screening have not been examined extensively. A few studies have assessed positive predictive value by correlating histopathologic findings with screening diagnoses2-6; although one study addressed the reproducibility of the screening examination itself, it reported interobserver agreement between dermatologists and dermatology nurses.6 Our study examines interobserver agreement between dermatologists in a community skin cancer screening setting.
