The capture-recapture method was used to estimate the sensitivity of case finding in two national STD surveillance systems : (I) STD registration at municipal health services (STD-MHS) ; (2) statutory notification by clinicians (NNS).
To identify those cases common to both surveillance systems, cases from 1995 were compared using individual identifiers.
Estimated sensitivities for syphilis were :
STD-MHS 31% (95% CI : 27-35%),
NNS 64% (56-71%) ;
and for gonorrhoea : STD-MHS 15% (14-18%),
NNS 22% (19-25%). The combined sensitivity of both systems was 76% for syphilis and 34% for gonorrhoea.
Differences in the sensitivity of the systems were significant.
The NNS was more sensitive than the STD-MHS, and the identification of cases was significantly more sensitive for syphilis than for gonorrhoea.
A stratified analysis showed comparable results for the two sexes.
Knowledge on the sensitivity of surveillance systems is useful for public health decisions and essential for international comparisons.
