||Development of an expert system for the interpretation of serial peak expiratory flow measurements in the diagnosis of occupational asthma
||Nov. 1999, Vol.56, No.11, p.758-764. Illus. 29 ref.
||A computer-assisted diagnostic aid (Oasys) which has been developed to separate occupational from non-occupational causes of airflow obstruction, of which asthma is the most common cause, is described. Oasys-2 achieved a sensitivity of 75% and a specificity of at least 94%; therefore peak expiratory flow monitoring combined with Oasys-2 analysis is better to confirm rather than to exclude occupational asthma. Both have been based on expert interpretation of peak flow measurements plotted as daily maximum, mean, and minimum, with the first reading at work taken as the first reading of the day. Oasys has been evaluated with independent criteria against measurements made in a wide range of occupational situations.
