[Routine gonorrhoeae cultures: a cost--benefit analysis on obstetric--gynaecological patients (author's transl)]

Report is made on the routine check up of Neisseria Gonorrhoeae cultures of 46.081 patients. 375 (0.81%) of these showed positive results. Of the 375 positive N. Gonorrhoeae cases 122 (33%) showed neither clinical symptoms nor anamnestic indications of Gonorrhoeae. The costs for the N. Gonorrhoeae cultures amounted to sfr. 18.407.-. Distributed on the 122 non-symptomatic and anamnestically mute cases there resulted costs of sfr. 148.-for each N. Gonorrhoeae case discovered by routine check up. The setting up a routine check up of Neisseria Gonorrhoeae cultures is therefore recommended.
