A random sample of the records of patients having barium meal examinations at a district general hospital was reviewed. In both males and females, there was no significant difference in the proportions of abnormalities between referrals from hospital doctors and general practitioners. Younger males were less likely to show abnormalities than older males, but there was no age difference in the proportions of abnormal barium meals in females. There was a smaller proportion of major abnormalities (19 per cent) in female than male patients (28 per cent). This study does not suggest that any reduction of direct access barium meal examinations for general practitioners is necessary.
对一家地区综合医院进行钡餐检查的患者记录进行了随机抽样审查。在男性和女性中，医院医生转诊患者和全科医生转诊患者的异常比例没有显著差异。年轻男性比老年男性出现异常的可能性更小，但女性钡餐异常比例在年龄上没有差异。女性患者中主要异常的比例（19%）低于男性患者（28%）。这项研究并不表明有必要减少全科医生直接进行钡餐检查的机会。
