Follow-up
Duration
Suggestion from BMJ Evidence-Based Medicine, in "A new arrival: evidence about differential diagnosis"[1]
For ≥80% of those patients evaluated, either the diagnoses must be established (by appropriate investigation), or to minimise missed diagnoses, there must be a follow up of ≥1 month for acute disorders and ≥1 year for chronic or recurring disorders.
