Retesting 3 to 4 months after treatment for those infected with chlamydia and/or gonorrhea has been recommended.
We compared various methods of encouraging return for retesting 3 months after treatment for chlamydia or gonorrhea.
In study 1, participants were randomly assigned to: 1) brief recommendation to return, 2) intervention 1 plus $20 incentive paid at return visit, or 3) intervention 1 plus motivational counseling at the first visit and a phone reminder at 3 months. In study 2, participants at 1 clinic were randomly assigned to 4) intervention 1, 5) intervention 1 plus phone reminder, or 6) intervention 1 plus motivational counseling but no telephone reminder.
Using multiple logistic regression, the odds ratios for interventions 2 and 3, respectively, compared with intervention 1 were 1.2 (95% confidence interval [CI], 0.6–2.5) and 2.6 (95% CI, 1.3–5.0). The odds ratios for interventions 5 and 6 compared with intervention 4 were 18.1 (95% CI, 1.7–193.5) and 4.6 (95% CI, 0.4–58.0).
A monetary incentive did not increase return rates compared with a brief recommendation. A reminder phone call seemed to be the most effective method to increase return.
A study comparing various methods of encouraging return for retesting 3 months after treatment for chlamydia or gonorrhea found that a reminder phone call seemed to be the most effective method and a monetary incentive was not effective.
