The prevalence of intermittent digital ischaemia (IDI) has been determined in a sample of 520 patients aged 20-59 selected from the list of a Hampshire general practice. Sixtythree cases were identified using a postal questionnaire (response rate 87 per cent) and, where possible (69 per cent), histories were confirmed by interview. The estimated prevalence of IDI was 8.3 per cent in men and 17.6 per cent in women. A minimum estimate based only on histories confirmed at interview was 5.0 per cent in men and 10.4 per cent in women. Of the 63 cases identified, 12 had consulted their general practitioner because of the problem but only two had been referred to hospital. We conclude that the course of IDI is generally benign.
在从汉普郡一家普通诊所的名单中挑选出的520名年龄在20至59岁之间的患者样本中,确定了间歇性指端缺血(IDI)的患病率。通过邮寄问卷(回复率87%)识别出63例病例,并在可能的情况下(69%)通过访谈确认病史。IDI的估计患病率在男性中为8.3%,在女性中为17.6%。仅基于访谈确认的病史得出的最低估计值在男性中为5.0%,在女性中为10.4%。在识别出的63例病例中,有12例因该问题咨询过全科医生,但只有2例被转诊至医院。我们得出结论,IDI的病程通常是良性的。
