[More and faster notification of infectious disease if notification is carried out by the laboratories instead of the diagnosing physician].

OBJECTIVE

To investigate if notification by the laboratories of a number of Group B diseases (meningococcal disease, whooping cough and hepatitis A) which according to the Communicable Disease Law of 999 must be reported to the local public health authority, would increase the number of reports and the speed at which the reports were made.

DESIGN

Comparative study.

METHOD: In the participating regions (Den Bosch and north-east Brabant) it was decided that the laboratories would notify the authorities of cases ofmeningococcal disease, whooping cough and hepatitis A. The notifications were compared with those from the middle-Brabant region which was used as a control. This took place in 1997/'98, prior to the start of the notification project and in 2000/'02 when it was running. The number of positive cases of infectious disease confirmed by the laboratories that were reported to the local health authorities and to the Inspectorate of Public Health Services was examined - this is known as the degree of notification. The number of days from diagnosis to notification of the local health authorities was also examined - this is known as the speed of notification.

RESULTS

The degree of notification for these three diseases improved from 6I-89% to 87-95% if the authorities were notified by the laboratories. In the control region the degree of notification improved from 29-4I% to 54-60%. The speed of notification increased significantly if notification was done by the laboratories.

CONCLUSION

Based on these results it is recommended that the Communicable Disease Law be adapted to allow the laboratories to notify the authorities of cases of infectious disease.
