May 2002 Estimating the Cost and Effectiveness of Different STI Management Strategies for Study Design First, the researchers evaluated the cost-effectiveness of different approaches to screening and treatment of STIs in sex workers: standard syndromic management, a combination of syndromic management and risk assessment, and use of laboratory evaluation in combination with risk assessment. Second, the investigators determined the cost-effectiveness of conducting follow-up visits for sex workers at different time intervals. They compared whether it was more cost-effective to have sex workers return for follow-up visits at health clinics every 30 days or every 90 days. This issue is important because sex workers spend time and lose earnings when they are required to make frequent visits to clinics, and their attendance is likely to decline if the perceived benefits are too low.
