In your next clinical consultation, you may well find yourself asking the question “What is the likelihood that this treatment will benefit this patient at this time?” Evidence-based practice answers this question with data collected under ideal conditions from a double-blind, randomised, placebo-controlled trial (RCT). However, what evidence-based practice doesn't tell us is that, when it comes to asthma and many other chronic diseases, only a minority of patients in your clinic would ever meet the eligibility criteria for these RCTs.

哮喘的有效性试验：SaLSA的时间到了？

在您的下一次临床咨询中，您很可能会问自己“这个时候该治疗对患者有利的可能性是多少？”的问题。循证实践使用在理想条件下从双盲，随机，安慰剂对照试验（RCT）中收集的数据回答了这个问题。但是，基于证据的实践并没有告诉我们，当涉及哮喘和许多其他慢性疾病时，您诊所中只有少数患者符合这些RCT的资格标准。
