Objective: The main purpose of this study was to assess the economic c
osts of sexually transmitted disease (STD) treatment and to identify o
pportunities for sustaining Bangkok's STD clinics. Design: A cost anal
ysis was used to assess the resources required to provide (i) STD serv
ices, (ii) additional services at STD clinics during the evening, and
(iii) outreach activities with commercial sex workers. The cost analys
is included a review of opportunities to increase sustainability throu
gh cost recovery and institutional restructuring. Results: The study r
evealed that the cost of providing services does differ significantly
across the five clinics analysed, with recurrent costs of day-clinic S
TD care varying from US$13-37 per patient reached. An analysis of expa
nded evening hours at STD clinics suggested that an investment of US$6
2 000 per year allowed an additional 2000 patients to receive STD trea
tment and that evening hours appear to offer greater convenience to pa
tients. It was also found that outreach activities initiated by the ST
D clinics and carried out in brothels have been used inexpensively (US
$0.20 per woman reached) to reach commercial sex workers with critical
information on STDs, including HIV. An analysis of opportunities for
cost recovery at public STD clinics indicated that although some resou
rces can be recovered, government support will continue to be required
. The cost recovery option believed to be most feasible for promoting
sustainability was a proposed charge of US$2-4 for STD clinic attender
s. This charge was projected to allow each clinic to recover between 1
1% and 22% of their recurrent costs. Conclusion: This study concluded
that there are numerous opportunities for promoting the financial sust
ainability of STD services at public clinics. It was also concluded th
at the existing outreach program is extremely inexpensive and is reach
ing people who are in need of the services that are being offered. How
ever, this study was not able to determine if it would be worthwhile t
o reopen public STD clinics during evening hours. (C) 1998 Lippincott
