This short report evaluates the feasibility of using electronic vending machines for dispensing oral, fluid, rapid HIV self-testing kits in Los Angeles County. Feasibility criteria that needed to be addressed were defined as: (1) ability to find a manufacturer who would allow dispensing of HIV testing kits and could fit them to the dimensions of a vending machine, (2) ability to identify and address potential initial obstacles, trade-offs in choosing a machine location, and (3) ability to gain community approval for implementing this approach in a community setting. To address these issues, we contracted a vending machine company who could supply a customized, Internet-enabled machine that could dispense HIV kits and partnered with a local health center available to host the machine onsite and provide counseling to participants, if needed. Vending machines appear to be feasible technologies that can be used to distribute HIV testing kits.  相似文献

High levels of HIV stigma are one of the main difficulties in engaging African-American and Latino men who have sex with men (MSM) in HIV testing. The availability of home HIV test and the possibility of self-testing in private may improve uptake and counteract stigma. This paper sought to determine the correlates of requesting home HIV test kits among a sample of MSM social media users. The odds of participants requesting a test kit were significantly associated with using social networks to seek sexual partners (aOR: 2.47, 95% CI: 1.07–6.06) and thinking it is easier to use social networks for seeking sexual partners (1.87, 1.2–3.12), uncertain HIV status (4.29, 1.37–14.4), and having sex under the influence of alcohol (2.46, 1.06–5.77). Participants who had not been tested for more than 6 months were more likely to request a test kit than those who were tested in the past 6 months (2.53, 1.02–6.37). Participants who frequently talked to others about having sex with men online were less likely to request a test kit (0.73, 0.56–0.92). By reaching people over social media and offering them access to test kits, we were able to reach at-risk individuals who were uncertain about their HIV status and had not been regularly tested. The findings of the study will help to inform future HIV testing interventions.  相似文献

Self-Testing for HIV (HIVST) is widely recognised as a feasible and effective means of increasing rates of testing and detection of HIV, particularly in non-testing and infrequent testing populations. Currently in Australia, the only means of accessing this technology is to purchase unregulated products on-line. A search of available on-line distributers was purposefully performed from the perspective of an English-speaking individual, with no clinical background or specific understanding of HIV testing practices, seeking to determine their HIV status. Purchased kits were assessed against a structured extraction tool based on the Australian Therapeutic Goods Administration (TGA) HIV testing clinical performance guidelines. In total, eight HIVST kits were purchased from seven different distributers. Analysis of the purchased kits and linked websites revealed that none met the TGA’s requirements for HIV testing kits intended for home use; none also conformed to the additional recommendations for information, quality and links to services developed from this study’s review of HIVST associated literature. People seeking HIVST kits are able to purchase sub-standard products that ill-serve their needs, and do so at a time of great personal vulnerability. The fact that Australians are willing to purchase and use these sub-standard products indicates HIVST is in demand. Health policy and models of service are needed in order to ensure people have access to a safe and effective registered device at prices that enable equity of access to all Australians, particularly those most at risk of HIV. Other countries awaiting access to regulated HIVST devices also need to consider the potential implications. Collaboration between manufacturers, distributers, regulatory bodies, service providers and the community is needed globally in order to ensure HIVST is embedded into testing methods in a manner that does not disrupt but rather safely and effectively increases HIV testing rates.  相似文献

High interest and a growing body of evidence suggest that HIV self-testing could help fill the HIV testing gap for populations who have been hesitant to access testing services through current mechanisms. Evidence from five of six studies funded by 3ie answers questions posed by the Kenyan government to understand the readiness of Kenyans for HIV self-testing. The findings suggest that Kenyans are generally ready for HIV self-testing. Most people would not only like to obtain self-test kits through public health facilities but also expect to be able to obtain them from pharmacies – easy access being a key factor for a distribution outlet. Respondents across the studies seem to understand the importance of counseling and confirmatory testing, although the decision to access services after an HIV self-test will certainly be influenced by the results of the test. Respondents do have some concerns about potential harms and abuses from HIV self-tests. These concerns are focused on what they expect others would do, rather than reflections of what they say they would do themselves. Additionally, most people believe that such concerns were mostly unwarranted and/or could be addressed.  相似文献

This paper explores the willingness to use and pay for HIV Self-testing (HIVST) among Australian gay and bisexual men (GBM). Bivariate and univariate multinominal logistic regression of data from an online survey was performed. Thirty-one (13%) had never HIV tested and 41.9% (88) were testing sub-optimally by Australian guidelines. Half (58.4%, 136) had never heard of HIVST, however, 56.2% (131) reported willingness to use HIVST, with sub-optimal (OR=2.13; p?<?0.01) and never-testers (OR=2.01; p?<?0.10) significantly more likely to do so than optimal-testers. Most were confident (51.7%, 119) or somewhat confident (29.1%, 67) accessing support following a reactive result, however, never-testers were significantly less confident compared to previous testers (OR=3.47; p<?0.05). Less than a quarter (23.6%, 57) were willing to pay for a kit with AUD$15 (R2 = 0.9882) the estimated preferred price. This research confirms that HIVST is an important and accepted adjunct to established HIV testing modalities, particularly among sub-optimal and never-testers and that online (61.6%, 143) or clinic-based (61.6%, 143) dissemination are preferred. Research examining how best to disseminate HIVST in a range of safe and effective models needs to continue to ensure HIVST is part of a comprehensive strategy that facilitates usage and linkages to care.  相似文献

ABSTRACT

Uptake of HIV testing remains lower among children and adolescents compared to adults. This study explored adolescents’ perceptions of HIV self-testing (HIVST) and caregivers’ perceptions of testing their children using an oral mucosal transudate (OMT) rapid HIV test (caregiver-provided testing). We conducted 31 interviews with adolescents aged 16–18 years and caregivers of children aged 2–15 years who received an OMT test. Participants described barriers to HIV testing including lack of privacy and the potential for discrimination by community members towards children and adolescents who received an HIV test. Most participants felt caregiver-provided testing and HIVST could address these barriers through increased privacy. Some participants expressed worry about their ability to correctly perform the OMT and their anxious reactions to a positive result. Counseling and assistance from health care workers were viewed as ways to alleviate concerns. Concerns shaped participants’ preferences for facility-based HIVST and caregiver-provided testing. Findings demonstrate HIVST performed by adolescents and caregiver-provided testing could increase the uptake of HIV testing. Concerns related to being able to test correctly and the availability of post-test counseling must be addressed in any future delivery mechanisms.  相似文献

This study aims to pilot and evaluate an integrated model for HIV self-testing (HIVST) service delivery in a peer-led Queensland community setting to increase access to HIVST, particularly for men who have sex with men (MSM) living in regional, remote and rural areas. It seeks to provide evidence that would overcome some of the key objections previously raised to HIVST.

Recruitment strategies have been designed to engage hard to reach MSM populations in testing. Awareness of the trial will be generated through advertising on social media platforms, including dating applications, word of mouth and HIV related websites. Participants will access an HIVST online ordering system hosted by a HIV community organisation. This system: (1) enables on-line informed consent; 2) gives clients the choice to accept verbal pre-test information from a trained peer test facilitator or not; and (3) allows for ordering of the HIVST kit after completion of an online survey (with demographic information and testing history etc.). Clients receive the kits via the post; and at 2 weeks receive a follow-up phone-call and SMS link to a post-test survey. If the test is non-reactive, clients can opt for test reminders. If reactive, referral to clinical services, peer navigation and support systems are provided.

This study addresses important gaps in understanding of acceptable and feasible methods to integrate HIVST into an existing peer-led testing service and into the broader suite of HIV testing options and services. The findings will inform the actions needed to enhance access to HIVST for MSM wishing to use this technology in Australia and elsewhere, especially those who have never tested and infrequent testers.  相似文献

ABSTRACT

HIV testing among female sex workers (FSWs) is an established global health priority. HIV self-testing (HIVST) seems to have the potential to address issues of confidentiality, privacy and convenience among this key population. HIVST, however, may result in unintended consequences as its implementation unfolds in a complex sex work context characterised by unequal power relations, stigma and high HIV prevalence. We aimed to explore the experiences of FSWs with HIVST in the context of retesting and antiretroviral usage in Blantyre, Malawi. We used an ethnographic approach to understand meanings and views around HIVST and retesting. We found high levels of retesting, especially among those on antiretroviral, two of which received “false-negative” results. We identified three broad narratives: (1) retesting in response to experiences in the sex work context, (2) retesting driven by the desire to self-monitor HIV-negative status, and (3) retesting in the hope of sero-reversion. The FSWs’ experiences indicate that the implementation of HIVST in this context is complex with potential for unintended harms such as coercive testing. HIVST programmes must include clear and appropriate messaging to reduce retesting while on ART and implement strategies to address FSW concerns and anxieties about the accuracy of their HIV-positive test results.  相似文献

艾滋病自检的形式包括自助采样送检和自测两种。虽然艾滋病自检的提出已有20多年的历史,但自检本身仍存在很大争议,一方面,艾滋病自检有利于保护检测者隐私,赋予人们自我管理感染艾滋病风险的权利,使得它在人群中有一定的需求;另一方面,自检又存在缺乏准确性、专业咨询和支持等问题,使得管理部门对放开自检心存顾虑。目前世界范围内,艾滋病自检基本处于研究阶段。中国对艾滋病自检研究很少,有必要加强相关研究,正确引导自检,扬长避短,使其为扩大艾滋病检测面服务。  相似文献
