## Indications for use
Annalise Enterprise CXR Triage Trauma is a software workflow tool designed to aid the clinical assessment of adult chest X-ray cases with features suggestive of pleural effusion and pneumoperitoneum in the medical care environment. The device analyzes cases using an artificial intelligence algorithm to identify findings. It makes case-level output available to a PACS or RIS for worklist prioritization or triage. The device is intended to be used by trained clinicians who are qualified to interpret chest X-rays as part of their scope of practice. The device is not intended to direct attention to specific portions of an image or to anomalies other than pleural effusion and pneumoperitoneum. Its results are not intended to be used on a standalone basis for clinical decision making nor is it intended to rule out specific critical findings, or otherwise preclude clinical assessment of X-ray cases. Standalone performance evaluation of the device was performed on a dataset that included supine and erect positioning. Use of this device with prone positioning may result in differences in performance. Standalone performance evaluation of the device was performed on a dataset where most cases were of unilateral right sided and bilateral pneumoperitoneum. Use of this device for unilateral left sided pneumoperitoneum may result in differences in performance. Specificity may be reduced for pleural effusion in the presence of scarring and/or pleural thickening.
