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.
