Background. – The associated factors contributing to a delay in mandatory tuberculosis notification in the Somme department, France, are not
yet known. The objective of this study was to analyze these factors.
Methods. – All reported cases of tuberculosis between 2007 and 2011 were retrospectively included. Univariate and multivariate analyses were
conducted to investigate the factors associated with a short time to notification, i.e., 48 h.
Results. – Between 2007 and 2011, a total of 175 cases of tuberculosis were reported to the Somme Regional Health Agency. Of the 145
(83.8%) cases of tuberculosis with at least one pulmonary location, 57.7% had a positive sputum smear. The mean time between the diagnosis of
tuberculosis and mandatory notification was 6.1 days. It was 2.6 days for tuberculosis cases with a positive sputum smear versus 8.3 days for cases
with a negative sputum smear; 2.0 days for severe cases and 6.3 days for simpler forms. In multivariate analysis, only a positive sputum smear was
significantly associated with a short time to mandatory notification (OR 2.44; 95%CI 1.18–5.00; P = 0.02).
Conclusion. – The time to mandatory notification is longer than recommended. Better collaboration between the parties involved in
tuberculosis control and their continuing medical education could reduce this delay in the Somme department.
