This study assessed the impact of automated telephone reminders on tuberculin skin test returns.
A total of 701 English-speaking and Spanish-speaking patients of a public health immunization program were randomly assigned to an intervention or a control group. Those in the intervention group received an automated telephone reminder to return for the reading of their skin test.
Automated telephone reminders significantly reduced return failures 53% (from 14% to 7%) when the scheduled interval between test administration and reading was three days, but had no impact for a two-day interval. Effectiveness of reminders did not differ significantly by patient age, gender, or language (English versus Spanish).
Results suggest the value of automated reminder calls for intra-appointment intervals as short as three days.
本研究评估了自动电话提醒对结核菌素皮肤试验复查的影响。
一项公共卫生免疫计划中的701名说英语和西班牙语的患者被随机分配到干预组或对照组。干预组的患者会收到自动电话提醒，告知其回来进行皮肤试验结果的读取。
当试验接种与结果读取的预定间隔为三天时，自动电话提醒显著降低了复查失败率53%（从14%降至7%），但对两天的间隔没有影响。提醒的有效性在患者年龄、性别或语言（英语与西班牙语）方面没有显著差异。
结果表明，对于短至三天的预约间隔，自动提醒电话具有价值。
