Log anything you do — a procedure, a case, a ward round, teaching you gave or attended, an audit, a presentation. Every entry is recorded twice over: objectively, as facts that can be counted and checked, and subjectively, in your own words. No account needed.
No patient identifiers. No names, hospital or file numbers, or anything that could identify a patient. Use your own reference such as "case 12" if you need to find it again.
