To determine how general practitioners in New Zealand view screening for prostate cancer and the extent to which this is undertaken in general practice.
A questionnaire survey of a random sample of 500 general practitioners.
Completed questionnaires were received from 317 of an eligible sample of 462. Approximately 50% believed digital rectal examination (DRE) and prostate specific antigen (PSA) were effective screening tests for prostate cancer and that asymptomatic men should be screened; 40% believed all men aged 50 years or more should be screened using either DRE or PSA. The majority of the general practitioners currently screen at least some of the men aged 50 years or more on their lists using DRE or PSA regardless of beliefs about the efficacy of the tests. The results also indicated that significantly more general practitioners in the age groups 50-59 years and 60 years and over believed asymptomatic patients should be screened with DRE or PSA.
Despite the absence of evidence to support screening for prostate cancer using DRE or PSA and the increasing number of professional organisations releasing guidelines and statements to that effect, the majority of the general practitioners who participated in this survey are screening some of their patients aged 50 years or more using DRE and/or PSA.
确定新西兰的全科医生如何看待前列腺癌筛查以及在全科医疗中进行前列腺癌筛查的程度。
对500名全科医生的随机样本进行问卷调查。
在462名符合条件的样本中，有317人返回了完整的问卷。约50%的人认为直肠指检（DRE）和前列腺特异性抗原（PSA）是有效的前列腺癌筛查测试，无症状男性应接受筛查；40%的人认为所有50岁及以上的男性都应使用DRE或PSA进行筛查。大多数全科医生目前至少对其名单上50岁及以上的部分男性使用DRE或PSA进行筛查，无论他们对这些测试的有效性持何种看法。结果还表明，50 - 59岁以及60岁及以上年龄组的全科医生中，明显有更多人认为无症状患者应使用DRE或PSA进行筛查。
尽管缺乏证据支持使用DRE或PSA进行前列腺癌筛查，且越来越多的专业组织发布了相关指南和声明，但参与本次调查的大多数全科医生仍在对其50岁及以上的部分患者使用DRE和/或PSA进行筛查。
