目的比较多次求询者与单次求询者的特征是否一致,并比较两类数据(人次数和人数)所反映的求询者的特征是否有差异。方法对2010-2011年多次求询者的基本情况数据进行描述和卡方检验。结果共为4628人提供5135人次自愿咨询检测(VCT)服务,其中多次求询者393人(8.5%),多次求询原因前三位的是:上次检测未过窗口期或再次发生高危行为的占51.4%(202人),HIV感染者配偶/固定性伴随访检测占21.4%(84人),HIV抗体初筛检测次数超过3次且结果均为阴性的恐艾者占11.5%(45人)。多次求询者在男性、大专及以上文化程度、15~29岁、商业异性性行为史以及HIV抗体初筛阴性中的比例较高。除HIV抗体初筛结果构成比外,两类数据反映的求询者特征没有差异。结论人次数数据基本上能够代替人数数据反映的求询者特征;减少不必要的重复检测是节约资源和规范服务的基础;应为多次求询者提供更有针对性的咨询检测服务。
Objective To compare the characteristics of multiple inquirers with single inquirers and compare the characteristics of inquirers reflected by the two types of data (the number of people and the number of people). Methods To describe and chi-square test the data of multiple inquirers in 2010-2011. Results A total of 4628 people provided 5135 voluntary counseling and testing (VCT) services, of which 393 (8.5%) were asked many times. The reasons for the top three are: the last test did not have a window or recurrence 51.4% (202 persons) were high-risk behaviors, 21.4% (84 persons) were spouses / regular partners of HIV-infected patients, 11.5% were HIV-positive patients who tested negative for more than 3 times, (45 people). Multiple inquiries in the male, college education and above, 15 to 29 years old, commercial heterosexual behavior history and HIV antibody screening negative in a higher proportion. There was no difference in the characteristics of the inquirers reflected by the two types of data except for the HIV screening results. Conclusions The number of people is basically able to replace the number of people reflected by the number of data characteristics of the query; reduce unnecessary duplication of testing is the basis for resource conservation and standardize services; multiple inquiries should provide more targeted advisory testing services.
