Serving the underserved: an HIV testing program for populations reluctant to attend conventional settings.

OBJECTIVES: We assess the contribution of a rapid-HIV testing program run by Médicos del Mundo and oriented to vulnerable populations reluctant to attend conventional settings. METHODS: We compare the program outcomes with a network of 20 HIV/STI clinics (EPIVIH) and the Spanish National Surveillance System (SNHSS). RESULTS: 33.3% of the new diagnoses were women (8.6% EPIVIH and 17.7% SNHSS). Transsexuals were 6.9% (1.9% EPIVIH), female sex workers 23.6% (2.0% EPIVIH) and 19.4% Sub-Saharan Africans (3.8% EPIVIH and 7.8% SNHSS). HIV prevalence in men was slightly higher than in the EPIVIH and almost twice among women. CONCLUSIONS: This program is contributing substantially to the promotion of HIV diagnosis in female sex workers, sub-Saharan Africans and transsexuals, which are less present at clinical settings.

Approval and potential use of over-the-counter HIV self-tests: the opinion of participants in a street based HIV rapid testing program in Spain.

HIV self-testing, not yet available in Spain, is a strategy thought to be able to increase the number of people tested and testing frequency. 3,373 attenders of a street-based HIV rapid-testing program gave their opinion on authorizing over-the-counter self-tests and a potentially shorter lead time if self-tests were available. 88.0 % of participants were in favor of authorization, 9.2 % had no clear opinion and 2.8 % were against. 54.6 % of men who have sex with men (MSM), 38.4 % of men who have sex with women and 36.3 % of women acknowledged a potential for lead time reduction. Potential lead time was associated with being ≥35 years, having a university degree, never injected drugs, previous HIV tests and being concerned about an HIV positive result, and in MSM, also having ≥5 partners. Self-testing seems a promising strategy for Spain: its authorization is supported by nearly all potential users and almost three quarters of MSM would have opted to advance their current testing if self-tests were available.

Low knowledge and anecdotal use of unauthorized online HIV self-test kits among attendees at a street-based HIV rapid testing programme in Spain.

OBJECTIVES: The objectives of this study were to estimate the percentage of potential users who know that unauthorized HIV self-tests can be purchased online and the percentage of those who have already used them, and to determine socio-demographic and behavioural correlates. METHODS: A self-administered questionnaire was employed to collect data from attendees at a street-based HIV testing programme. Logistic regression for rare events was performed. RESULTS: Of the 3340 participants, 5.3% (95% confidence interval (CI) 4.5-6.0%) had knowledge of self-tests being sold online and 7.5% (95% CI 6.6-8.5%) thought they existed but had never seen them; only 0.6% (95% CI 0.3-0.9%) had ever used one. Knowing that self-tests are sold online (odds ratio (OR) 3.6, 95% CI 2.4-5.4) and using them (OR 7.3, 95% CI 2.2-23.8) were associated with having undergone more than two previous HIV tests. Use was also associated with being neither Spanish nor Latin American (OR 3.8, 95% CI 1.2-12.0) and with having a university degree (OR 0.2, 95% CI 0.1-0.7). CONCLUSIONS: At the time of the study, the impact on the population of issues related to the use of unauthorized tests was very low. However, media coverage following the approval of self-testing in the USA might have changed the situation.

Who and how many of the potential users would be willing to pay the current or a lower price of the HIV self-test? The opinion of participants in a feasibility study of HIV self-testing in Spain / ¿Quiénes y cuántos potenciales usuarios estarían dispuestos a pagar el precio actual o un precio menor de un autotest de VIH? Opinión de los participantes en un estudio de factibilidad del autotest de VIH en España

INTRODUCTION: We estimate the proportion of participants willing to pay the US price (€ 30) or € 20 for an HIV self-test and analyse their associated factors. METHODS: In a street-based testing program, 497 participants in a feasibility self-test study answered the question, "What would be the maximum price you would be willing to pay for a similar test to this one so you can use it at your convenience?" RESULTS: Only 17.9% would pay ≥ €30, while 40.0%, ≥ €20. In the logistic regression, paying more was associated with being tested outside the campuses and having paid or been paid for sex. CONCLUSION: In Spain, self-testing would not have an impact unless it became more affordable to potential users

INTRODUCCIÓN: Estimamos la proporción de participantes dispuestos a pagar por un autotest de VIH su precio en EEUU. (30 €), o 20 €, y analizamos factores asociados. MÉTODOS: En un programa de diagnóstico ofertado en la calle, 497participantes de un estudio de factibilidad del auto-test respondieron a la pregunta: ¿Cuál sería el precio máximo que estarías dispuesto a pagar por una prueba como esta para poder realizártela cuando estimaras oportuno?. RESULTADOS: El 17,9% pagaría ≥ 30 € y el 40,0% ≥ 20 €. En la regresión logística pagar más estuvo asociado con participar fuera de las universidades y haber pagado o sido pagado por sexo. CONCLUSIÓN: El autotest no tendrá impacto en España si su precio no disminuye a un valor más asequible para los potenciales usuarios

Highly visible street-based HIV rapid testing: is it an attractive option for a previously untested population? A cross-sectional study.

BACKGROUND: Given the shortage of community-based HIV testing initiatives in resource-rich countries not targeting most-at-risk populations, we aimed to evaluate whether a highly visible mobile programme promoting and offering rapid HIV testing in the street can attract persons at risk for infection who have never been tested. METHODS: Between 2008 and 2011, the programme served 7552 persons in various Spanish cities who answered a brief questionnaire while awaiting their results. The factors associated with being tested for the first time were analysed using two logistic regression models, one for men who have sex with men (MSM) and the other for only heterosexual men (MSW) and women. RESULTS: 3517 participants (47%) were first-time testers (24% of MSM, 56% of MSW and 60% of women). Among them, 22 undiagnosed HIV infections were detected with a global prevalence of 0.6% and 3.1% in MSM. Undergoing a first HIV test was independently associated with age <30, being from Spain or another developed country, lack of university education, having fewer partners, having had unprotected sex with casual partners and not having been diagnosed with a sexually transmitted infection. In heterosexuals, also with never injected drugs, and in MSM, with not being involved in the gay community. Among those tested for the first time, 22% had never thought of being tested and 62% decided to be tested when they passed by and noticed the programme, regardless of their previous intentions. CONCLUSIONS: This community programme attracted a substantial number of persons previously untested and particularly hard to reach, such as those with low education and MSM who were least involved in the gay community. Programme visibility was a decisive factor for almost two of every three persons who had never been tested.

Supervised blood-based self-sample collection and rapid test performance: a valuable alternative to the use of saliva by HIV testing programmes with no medical or nursing staff.

OBJECTIVES: Some saliva-based HIV testing programmes have resulted in an unacceptable percentage of false positives. Many countries require blood-based testing programmes to have doctors/nurses. The authors evaluate whether, after brief training and under the supervision of a skilled counsellor, blood-based self-sample collection and rapid test performance could be a valuable alternative. METHODS: 208 Spanish-speaking attendees at a street-based HIV testing programme in Madrid participated in the study. Participants were tested twice, first in the study and then in the programme, using the same finger-stick whole-blood rapid test (Determine HIV-1/2 Ag/Ab Combo®). Based on previously adapted instructions, the study counsellor explained the procedure to follow throughout the test. Participants then performed the test under the guidance of the counsellor. Demographic and risk behaviour data were collected by a self-administered questionnaire. The test results in the programme and the study were read by the study counsellor. RESULTS: 99.0% (95% CI 96.6% to 99.9%) of participants had a valid result in the study test, the same percentage as in the programme test conducted by the doctor/nurse. Two persons had invalid test results in both the study and the programme, but they were not the same persons. CONCLUSION: The study provides clear evidence that this methodology is a valuable alternative to saliva for HIV testing programmes when medical or nursing staff required to take blood samples is not available.
