description
PEIRS appends interpretative comments to pathology reports. The knowledge aqusition strategy is the
Ripple Down Rules method, which has allowed a pathologist to build over 2300 rules without knowledge engineering or
programming support. New rules are added in minutes, and maintenance tasks are a trivial extension to the pathologist's routine duties. PEIRS commented on about 100 reports/day. Domains covered include thyroid function tests, arterial blood gases, glucose tolerance tests, hCG, catecholamines and a range of other hormones.
