Data management and quality control
Detailed patient data including demographics, APGAR scores, reason for intubation, and patient outcome at 30 days of life were collected using the patient data collection form. This form was also used to collect data on the clinical and POCUS assessments of the ETT position (Appendix 1). After the data was collected it was transcribed into REDCap.
For quality assurance, the first 200 scans completed by POCUS users in this study were sent for review to a non-AKUH POCUS expert not involved in the study intervention. These files were deidentified and sent in Mpeg4 video format using a secure online file transfer program. The expert rated both the image quality and the interpretation of the video files.
