During 11 years of an open-access endoscopy service for general practitioners the proportion of positive diagnoses has remained relatively constant. There has been a progressive fall in the incidence of duodenal ulcers but an increase in oesophagitis which is now the single most commonly detected abnormality. The number of barium meal requests has fallen by approximately 50%. A study of cimetidine prescribing suggests that use of the open-access service results in fewer inappropriate prescriptions.
在为全科医生提供开放获取式内镜检查服务的11年中，阳性诊断的比例一直保持相对稳定。十二指肠溃疡的发病率逐渐下降，但食管炎的发病率有所上升，食管炎现已成为最常检测到的单一异常情况。钡餐检查申请数量下降了约50%。一项关于西咪替丁处方的研究表明，使用开放获取式服务会减少不适当的处方。
