Retrospective scenario flowchart example. Example of a RetroGuide osteoporosis scenario flowchart with analytical steps. This flowchart can operate on retrospective data because it does not require interaction with a clinician. All steps of the flowchart involve searching for a prior EHR event. The following logic is represented: (1) In patients with a fracture after age 65; (2) ensure female gender; (3) ensure that patient did not have a bone mineral density test performed; (4) ensure that no osteoporosis prevention drug has ever been prescribed; and (4) conclude that the patient is at increased risk for fractures.
