The accuracy and reliability of COVID-19 testing are critical to limit transmission. After observing variability in testing techniques, we otolaryngologists at a tertiary medical center initiated and evaluated the impact of nasopharyngeal and oropharyngeal swabbing training, including video instruction, to standardize sampling techniques and ensure high-quality specimens.
Participants in the training were employees (N = 40). Training consisted of an instructional video on how to perform nasopharyngeal and oropharyngeal swabs and a live demonstration. Participants completed pre- and posttraining surveys assessing their knowledge and confidence in performing nasopharyngeal and oropharyngeal swabs. They then performed swabbing on partners, which was graded per a standardized checklist.
Mean scores for knowledge-based questions and confidence in swabbing were significantly higher after the training session (both < .001). All participants scored ≥6 of 8 on the posttraining checklist. Ninety-five percent rated the video as very or extremely useful.
Specialized instruction for nasopharyngeal swabbing improved participants' knowledge-specifically, the appropriate head position and minimum swab time in nasopharynx-and their confidence. After the training, their swabbing execution scores were high.
Video-assisted hands-on instruction for nasopharyngeal swab sampling can be used to standardize teaching. When prompt and accurate testing is paramount, this instruction can optimize procedural technique and should be used early and often. In addition, there may be a professional responsibility of otolaryngologists to participate in such initiatives.
新型冠状病毒肺炎（COVID-19）检测的准确性和可靠性对于限制传播至关重要。在观察到检测技术存在差异后，我们一家三级医疗中心的耳鼻喉科医生开展并评估了鼻咽和口咽拭子采样培训（包括视频指导）的影响，以规范采样技术并确保高质量样本。
培训参与者为员工（N = 40）。培训包括一段关于如何进行鼻咽和口咽拭子采样的教学视频以及现场演示。参与者完成培训前和培训后的调查，评估他们在进行鼻咽和口咽拭子采样方面的知识和信心。然后他们对同伴进行拭子采样，并根据标准化清单进行评分。
培训后，基于知识的问题平均得分和拭子采样信心均显著更高（均P <.001）。所有参与者在培训后清单上的8项中得分≥6分。95%的人将视频评为非常有用或极其有用。
鼻咽拭子采样的专业指导提高了参与者的知识——特别是鼻咽部合适的头部位置和最短拭子采样时间——以及他们的信心。培训后，他们的拭子采样执行得分很高。
视频辅助的鼻咽拭子采样实践指导可用于规范教学。当快速准确的检测至关重要时，这种指导可以优化操作技术，应尽早且经常使用。此外，耳鼻喉科医生可能有参与此类举措的职业责任。
