The interval between when a clinical appointment is created and when it occurs may affect the rate of missed and cancelled appointments, affecting access and loss to follow-up, key component of quality.
We examined this relationship in various clinic types across Veterans Health Administration clinics nationwide.
As the interval increased, the missed appointment rate increased from 12.0% at day 1 to 20.3% at day 13, then remained constant. Cancellation rates increased steadily from 19% during month 1 to 50% by month 12.
Scheduling interval has a modest effect on missed appointment rates but a large effect on cancellation rates.
从创建临床预约到预约发生之间的间隔时间可能会影响失约和取消预约的发生率，进而影响医疗服务的可及性以及随访失访情况，而随访是医疗质量的关键组成部分。
我们在全国退伍军人健康管理局各诊所的不同诊所类型中研究了这种关系。
随着间隔时间增加，失约率从第1天的12.0%上升至第13天的20.3%，然后保持稳定。取消率从第1个月的19%稳步上升至第12个月的50%。
预约间隔时间对失约率影响较小，但对取消率影响较大。
