Objective: To compare the efficacy of a short messaging service (SMS) text messaging and phone reminder to improve attendance rates at a health promotion center. Methods: A total of 1 859 participants who had scheduled appointments in the health promotion center of our hospital from April 2007 to May 2007 were enrolled in the study and randomly assigned into 3 groups: control (no reminder) group, SMS text messaging reminder group and telephone reminder group. Attendance rates and costs of interventions were collected. Results: A total of 1848 participants were eligible for analysis. Attendance rates of control, SMS and telephone groups were 80.5%, 87.5% and 88.3%, respectively. The attendance rates were significantly higher in SMS and telephone groups than that in the control group, with odds ratio 1.698, 95% confidence interval 1.224 to 2.316, P=0.001 in the SMS group, and odds ratio 1.829, 95% confidence interval 1.333 to 2.509, P〈0.001 in the telephone group. However, there was no difference between the SMS group and the telephone group (P=0.670). The cost effectiveness analysis showed that the cost per attendance for the SMS group (0.31 Yuan) was significantly lower than that for the telephone group (0.48 Yuan). Conclusion: SMS and telephone are effective reminders for improving attendance rate at a health promotion center. SMS reminder may be more cost-effective compared with the telephone reminder. 相似文献

伪基站,也称为短信群发系统、小区短信发射系统等,均为地下工厂生产的三无产品,互联网上也能看到许多此类广告信息。伪基站不与公众移动网络相连,不能提供移动业务,使用时多将伪基站装于车内,在人群密集的街道小区移动发射,自动骗取其覆盖范围内的手机IMSI,使其接入伪基站,然后强”发进广告、诈骗等垃圾短信,令手机用户和运营商不堪其忧。 相似文献

最开始对曾国藩“拖,也是一种工作方式”这句话有体会,是因和一位博友的电话往来。我发现一个很有意思、也很让我不解的情况:无论什么时候给这位博友打电话,总是不接,等个一小时两小时的,短信发过来说,刚才开会了,有事吗? 相似文献

近年来,垃圾短信愈发泛滥,这种行为不但极大危害了用户的切身利益,而且对于联通的品牌打造也制造了很大的障碍。因此,对运营商的监管提出了更高的要求。该文综合比对了主流的垃圾短信拦截方案,最后明确了所采用的基于发端短信中心实时控制的垃圾短信拦截方案。通过采用系统自动处理和人工审核相结合的方式,垃圾短信治理工作取得了显著的成果。最后,该文结合目前垃圾短信治理的形势,对最新的基于可疑度的垃圾短信拦截机制进行了介绍,对后期的治理工作提出了展望。 相似文献
