To find the differences between telephone and mail interview respect on answer rate, economic cost and characteristics of participants. To determine the knowledge of our diabetics about their disease.
A descriptive transversal study.
Primary care Centro de San Gregorio, Telde, Las Palmas.
The diabetics type 1 and 2 (n = 566) of our centre, whose ages were 18-70 years. In order to apply the same health questionnaire through two different ways, we divided the sample into two random groups: mail group (n = 283) and telephone group (n = 283).
The global answer rate was 51.6% (292 patients), 48% in the mail group (136 patients) and 55% in the telephone group (156 patients). The total cost of the mail survey was 41,000 pts. (104 pts. per mail), and the cost of telephone survey was 5.100 pts. (25.5 pts. per useful call). In the whole sample, we observed women more frequently in the answer group (56% of 292) than in the no answer group (44% of 274) (CI 95% 8.1-12.8). Also, in the answer group, the age was greater than in the no answer group (58.8 +/- 9.8 yr vs. 55.8 +/- 12.5 yr) (CI 95% 1.14-4.8). When we analyzed gender and age in each group, we observed the same differences in the telephone group but not in the mail group. More than the half questionnaire were correctly answer by 64% (167 patients). In the telephone group the "fit" rate was greater (70.6% of 153) than in the mail group (55.7% of 106) (CI 95% 3.2-26.6).
A suitable answer rate was reached through both methods of interview, but telephone survey's was smaller. In the mail group, both genders and all ages groups answered in the same way. The knowledge of our diabetics about their disease was like as the found in another studies.
找出电话访谈和邮件访谈在应答率、经济成本及参与者特征方面的差异。确定我们中心糖尿病患者对自身疾病的了解情况。
描述性横断面研究。
拉斯帕尔马斯省特尔德市圣格雷戈里奥初级保健中心。
我们中心年龄在18至70岁之间的1型和2型糖尿病患者（n = 566）。为了通过两种不同方式应用相同的健康调查问卷，我们将样本随机分为两组：邮件组（n = 283）和电话组（n = 283）。
总体应答率为51.6%（292例患者），邮件组为48%（136例患者），电话组为55%（156例患者）。邮件调查的总成本为41,000比塞塔（每份邮件104比塞塔），电话调查的成本为5,100比塞塔（每个有效电话25.5比塞塔）。在整个样本中，我们观察到应答组中的女性（292例中的56%）比未应答组中的女性（274例中的44%）更常见（95%置信区间8.1 - 12.8）。此外，应答组的年龄大于未应答组（58.8 ± 9.8岁对55.8 ± 12.5岁）（95%置信区间1.14 - 4.8）。当我们分析每组的性别和年龄时，在电话组中观察到相同的差异，但在邮件组中未观察到。超过一半的问卷由64%（167例患者）正确回答。电话组的“符合”率（153例中的70.6%）高于邮件组（106例中的55.7%）（95%置信区间3.2 - 26.6）。
两种访谈方法均达到了合适的应答率，但电话调查的应答率较低。在邮件组中，各性别和各年龄组的回答方式相同。我们中心糖尿病患者对自身疾病的了解情况与其他研究中发现的情况相似。
