DESIGN Single centre randomised controlled trial. INTERVENTION Allocation of referred patients to outreach or main base consultation appointments. OUTCOME MEASURE The outcome of consultation, the cost and duration of the visit and the carer/patient's perceptions of the visit. RESULTS There were no differences in outcome of the consultation. While consumer travel costs and the duration of appointments were significantly higher for the main base clinics, these differences were not great. However, consumers preferred to attend an appointment in an outreach clinic. CONCLUSIONS There do not appear to be marked advantages or disadvantages in providing consultation appointments for orthodontics in outreach clinics.

正畸外展诊所-无明显优势或劣势。

设计单中心随机对照试验。干预将转诊患者分配到外展或主要基础咨询机构。结局度量咨询的结果，访问的费用和持续时间以及护理人员/患者对访问的看法。结果咨询结果无差异。虽然主要基础诊所的消费者差旅费用和预约时间明显较高，但这些差异并不大。但是，消费者更愿意参加外展诊所的预约。结论在外展诊所为正畸医生提供咨询预约似乎没有明显的优势或劣势。
