1. A Cost-Effectiveness Evaluation of the Sexually Transmitted Disease (STD) Prevention Program at the Hampden County Correctional Center, Massachusetts Gift T1, Conklin T2, Lincoln T2, Miller A3, Tuthill R3, Whelan M4, Irwin K1 1Centers for Disease Control and Prevention, Atlanta, GA; 2Hampden County Correctional Center, Ludlow, MA; 3University of Massachusetts-Amherst, Amherst, MA; 4 Massachusetts Department of Public Health

2. Background Inmates in correctional institutions are an important population for STD prevention Inmatesí sex partners also frequently have high STD rates STD testing and treatment programs must often compete with other correctional healthcare programs Cost-effectiveness evaluation is a tool that can: guide resource allocation decisions quantify the impact of correctional STD testing programs on community health

3. Background-2 Hampden County Correctional Center (HCCC) STD Program: Intake screening for chlamydia Leukocyte esterase test (LET) Nucleic acid amplification test (NAAT; LCxģ, Abbott Laboratories) Gonorrhea testing Performed if symptoms, risk factors, or LET results warrant Nucleic acid probe test (probe; Gen-Probe PACEģ 2 GC; Gen-Probe, Inc.)

4. Objective Determine the cost and cost-effectiveness of universal vs. targeted screening for chlamydia and gonorrhea in male inmates at intake

5. Methods-Data Sources Test Data Test results provided by Massachusetts Dept. of Public Health (MDPH) Test performance parameters: NAAT for chlamydia, probe for gonorrhea: literature estimates LET: MDPH Costs Labor costs: time-motion studies at HCCC Partner services costs: literature estimates Testing, treatment, overhead, and supply costs: HCCC Sequelae costs (epididymitis, PID): literature estimates

7. Methods-Program Alternatives Four program alternatives were modeled: 1) Present Practice Screen all males for chlamydia with LET and NAAT Offer probe test for gonorrhea if: Inmate is symptomatic, discloses risk factors, or LET is positive 2) Age-based testing (Under 25 years of age) Same as present practice for inmates < 25 years of age symptom-based testing for inmates over the age cutoff 3) Age-based testing (Under 30 years of age) Same as (2) except upper age cutoff is 30 4) Symptom-based testing only Only test inmates (all ages) who present with symptoms for chlamydia and gonorrhea

8. Descriptive Statistics

10. Results Data shown are for 1000 male inmates with the prevalences shown in the descriptive statistics table All costs in 2001 dollars

11. Results

13. Limitations Some data taken from literature: Partner services cost and effectiveness Cases of PID in partners Cases of gonorrhea in male inmates Age-based prevalence of chlamydia and gonorrhea may not be constant across time Chlamydia program benefits not included: reduction in HIV transmission due to treated chlamydial infections increased HIV counseling and testing opportunities resulting from STD diagnoses

14. Conclusions Chlamydia and gonorrhea screening: can detect and treat a high proportion of both infections among male inmates is more effective than restricting testing to symptomatic inmates only may lead to the detection and treatment of PID in their female sex partners Age-based screening has the potential to reduce program costs with little loss in effectiveness.
