Resumen:	Objective: The objective was to determine the mean duration of diagnosis delay for patients with myasthenia gravis from five European countries and explore the impact of >1 year diagnosis delay. Methods: Patients with myasthenia gravis (N = 387) from Europe (France/Germany/Italy/Spain/United Kingdom) and their physicians participated in the Adelphi Real World Myasthenia Gravis Disease Specific Programme™. Diagnosis delay (time from symptom onset to diagnosis) was calculated and characteristics described for patients experiencing >1 year and ≤1 year diagnosis delay. Denominators varied according to outcome as missing data were not imputed. Results: Mean (standard deviation) diagnosis delay was 363. 1 (520. 9) days, and 27. 1% (105 out of 387) of patients experienced diagnosis delay >1 year. Among patients with >1 year and ≤1 year diagnosis delay, respectively, 69. 2% (72 out of 104) and 17. 4% [45 out of 259] had initially received a different diagnosis (physician-reported); 40. 0% (42 out of 105) and 24. 1% (68 out of 282) were Myasthenia Gravis Foundation of America class III at the time of the survey (physician-reported); 72. 4% (76 out of 105) and 61. 3% (173 out of 282) had fatigue (subjective physician reporting from a pre-selected list of symptoms); 30. 5% (32 out of 105) and 17. 4% (49 out of 282) had anxiety and 21. 9% (23 out of 105) and 13. 1% (37 out of 282) had depression (both subjective physician reporting from a pre-selected list, Likert-style); and mean (standard deviation) MG-QoL-15r score was 14. 4 (5. 50) and 12. 6 (7. 84) (self-reported by N = 43 and N = 74 patients, respectively). Interpretation: More than a quarter of patients with myasthenia gravis experienced diagnosis delay of >1 year. These patients had a different clinical profile with regards to severity, symptoms, comorbidities and MG-QoL-15r score, compared with patients experiencing ≤1 year diagnosis delay.
