What is the correct form to use for making a variance report?

The correct choice for making a variance report is EMS System Variance Form #903. This form is specifically designed for documenting variances in emergency medical services, providing a standardized method for capturing the necessary information regarding any deviations from established protocols or procedures. Using the designated form ensures that reporting is consistent, thorough, and in compliance with regulatory standards, which is essential for maintaining quality assurance and accountability within the EMS system.

In the context of the other options, while they may refer to forms or reports that could be part of the overall reporting process, only EMS System Variance Form #903 is explicitly tailored for variance documentation, making it the most appropriate choice for the purpose of that report.
