There are approximately 40,000 new HIV infections in the United States each year. The estimated average lifetime cost of treating one HIV infection is $195,000. Relative to the size and costliness of the epidemic, government funds for prevention are scarce. To help decisionmakers allocate funds effectively, the RAND Corporation developed a mathematical model of the cost of a wide variety of HIV prevention interventions. The model uses a constant total budget of $400 million annually, which is within the $415 million budgeted in 2004 to state and local health departments for HIV prevention. The most cost-effective interventions (those that prevented the largest number of infections per dollar spent) are shown in the table.
|Intervention||People Reached||Annual Cost of Intervention||Infections Prevented||Cost Per Infection Prevented|
|Educational videos in STD clinics||2,000,000||$2,700,000||580||$4,700|
|Notifying sexual partners||54,000||$13,500,000||2,230||$6,100|
|Community outreach (Mpowerment modela)||600,000||$109,096,000||8,921||$12,000|
|STD screening at HIV clinics||467,000||$18,680,000||1,606||$12,000|
|Implementing needle exchange in high-prevalence areas||1,000,000||$30,380,000||2,291||$13,000|
|Mass media campaigns||70,000,000||19,999,000||1,131||$18,000|
|Opinion leaders programs||600,000||$22,851,000||994||$23,000|
|Implementing needle exchange in medium-prevalence areas||600,000||$18,228,000||388||$47,000|
|Increasing condom availability/accessibility||24,905,725||$90,566,000||1,920||$47,000|
|HIV counseling and testing (one-on-one)||1,000,000||$74,000,000||700||$110,000|
