A survey was carried out in Portsmouth to find out what general practitioners knew about colorectal cancer and what their views were on screening. A random sample of general practitioners was interviewed by questionnaire and the remainder asked to complete the questionnaire themselves. The overall response rate was 62%. There was a higher response rate from women doctors and from the group that was interviewed. For some questions there was a difference in the pattern of responses given by the interview group and the group who completed the questionnaire themselves.The level of knowledge of colorectal cancer varied according to which aspect was questioned. The general practitioners knew the symptoms well but were less aware of the vital statistics and risk factors. Most doctors were not in favour of screening by testing for faecal occult blood.
在朴茨茅斯进行了一项调查，以了解全科医生对结直肠癌的了解程度以及他们对筛查的看法。通过问卷调查对全科医生的随机样本进行了访谈，其余的则要求他们自己填写问卷。总体回复率为62%。女医生以及接受访谈的组的回复率更高。对于一些问题，访谈组和自己填写问卷的组给出的回答模式存在差异。对结直肠癌的了解程度因所询问的方面而异。全科医生对症状了解得很好，但对重要统计数据和风险因素的了解较少。大多数医生不赞成通过检测粪便潜血进行筛查。
