大多数被诊断患有喘的成年人可能没有这种情况. 重新评估喘诊断对于准确的患者管理和治疗至关重要.
科学领域:
- 肺病学
- 临床医学
- 流行病学
背景情况:
- 喘是一种慢性呼吸道疾病,成年人的自发缓解率尚不清楚.
- 成人喘诊断的长期稳定性需要进一步调查.
研究的目的:
- 评估是否有可能排除目前的喘,并安全地停止在医生诊断的成年人中服用喘药物.
- 评估患有喘病史的成人的诊断准确性和长期结果.
主要方法:
- 一项前性多中心队列研究涉及加拿大10个城市701名被医生诊断为喘的成年人.
- 参与者接受了气管测量,支气管挑战测试和药物逐渐减少;没有喘证据的参与者被跟踪了一年.
- 对医生的诊断实践进行了审查,以评估初始喘治疗的适当性.
主要成果:
- 在药物断奶和重新评估后,目前的喘在33. 1%的参与者中被排除在外.
- 一小部分患者 (2. 0%) 患有严重的心脏呼吸系统疾病,但被误诊为喘.
- 与确诊喘患者相比,被排除喘患者在初始诊断时接受空气流量限制测试的可能性较小.
结论:
- 在重新评估和停药后,33. 1% 的成年人无法确认医生诊断的喘.
- 在不能确定确诊的成年人中,需要重新评估喘诊断.
- 这些发现突显了喘的潜在过度诊断以及严格诊断确认的重要性.
