Money Well Spent: Opt-Out Testing in Prisons Can Catch STD Cases and Save Taxpayers Money in the Long Run
Opt-out testing is a method where everyone who engages a particular care setting will be tested unless they decline. Due to laws that vary from state to state, consent still must be acquired in most instances. Fortunately, verbal consent (which must still be documented in the medical record) is acceptable in most cases. This is important because high-volume settings such as jails and emergency rooms must have streamlined and efficient procedures to screen as many patients as possible. Any additional steps, such as finding and filling out a lengthy written consent form, adds substantial time to each patient encounter.
Once the patient has consented and agrees to participate in opt-out screening, they are sent for an HIV test. There are basically two major types of HIV tests that can be used in an opt-out setting: ELISA antibody tests (blood) or a rapid test (finger stick or oral swab). The advantages of rapid testing include being less invasive than a blood draw (no needles in veins), results in minutes, and most importantly, the ability to give the preliminary result to the patient before they are gone. The advantages of plasma ELISA testing include lower cost, delayed results (a benefit if patients are not stable enough to hear results immediately), and less utilization of space and staffing in a busy intake setting.
Delivering test results may seem like it should not be an issue in a jail setting where you have a captive audience to give results from a slower test such as an ELISA. The reality is that many detainees leave jails in hours to days depending on their charges, are released on home-monitoring, or are bailed out. Waiting even two or three days may mean up to 30% of those tested might not receive their result. Furthermore, is a jail intake facility an ideal place to tell someone for the first time they probably have HIV? Intake facilities are generally hot, crowded, high-pressure environments where there is little real privacy, if any. Incoming detainees are often intoxicated or coming down from a high, possibly angry about being arrested, mentally unstable (especially the people with severe mental health concerns), and physically and emotionally exhausted. Imagine a health care provider telling you your result, then sending you back out into a bullpen with 60 other detainees who are yelling, jostling for space, and maybe even reading the new look of shock on your face.
In a prison setting, most inmates have a clearly defined sentence. The health care staff knows the exact date of release from the facility, and therefore, there's a higher probability that those who are tested will receive their result. Additionally, by the time inmates reach prison, they are usually sober, better rested (as compared to the day they went to jail), and more emotionally and mentally stable. In resource-limited settings, including correctional facilities, screening with a less-expensive test (ELISA) may make expanded screening via opt-out more palatable to the budget-makers. Lastly, with known discharge dates, linkages to HIV care in the community become at least a little easier than they are in a jail setting (where one never really knows if or when the patient will be leaving).
As a real-world example, in 2006-2007, Washington, D.C. began expanded routine HIV screening in health care settings, including jails. The number of HIV tests performed increased by more than 68% in just one year simply by implementing the 2006 CDC recommendation for opt-out HIV screening.2 Not only were more tests conducted, but more results were available and delivered. This ultimately led to more patients becoming linked to care in their communities, and this led to more diagnoses made in an earlier stage of the disease (the average baseline CD4 went from 262 to 332 in the first year alone). In addition, more people aware of their status means more people on treatment. More people on treatment means less chance of infecting new partners. That was clearly shown with HPTN 052, a study of more than 1,700 couples in which successful treatment of the HIV-positive partner led to a 96% decrease in transmission. Awareness of one's HIV status also often means behavioral changes to protect partners. Fewer newly infected people means additional benefits to the community at large.
With renewed support from the county government, the Cook County Jail in Chicago began opt-out HIV and STI (sexually transmitted infection) screening in April 2011 for females entering the facility. More than 7,000 female intakes occurred from April through the end of 2011. More than 50% agreed to participate in HIV opt-out screening, and more than 60% in gonorrhea and Chlamydia screening. This process nearly tripled the number of HIV, syphilis, and GC/Chlamydia tests performed in the full calendar year of 2010. Many of these women remained in the facility long enough to not only receive their results, but to complete treatment (in the case of GC/Chlamydia) or linkage to care (in the case of those diagnosed with HIV). With "second-chance" testing offered at later times during their incarceration, an additional 20-30% of women ultimately agreed to be tested. The Chicago Department of Public Health was notified of any women leaving the jail before their results were available in order to attempt to locate them in their communities to provide treatment, as well as to notify sexual partners.
You might still be asking, "So why does this matter to me?" Remember, the majority of men and women entering a jail do not go to prison or otherwise just disappear. They return to their communities, bringing any untreated communicable diseases they have with them. With government budgets stretched thin, focusing limited resources to sites with the ability to have the greatest impact is wise. Some people may harbor resentment that tax dollars are being used to improve the health of people who may have broken the law, but this is shortsighted. In the long run, spending your tax dollars in jails and prisons for HIV and STI testing and treatment has a major downstream benefit to the broader community.
