RESUMEN

Existing participatory research approaches have failed to identify innovative methods that overcome the persistent barriers to adolescent sexual and reproductive health service demand and access. Increasingly, programmers have turned to human-centered design (HCD), a problem-solving process that centers the needs, perspectives, and experiences of people, when developing solutions to complex SRH challenges. This article describes the application of a youth-engaged version of HCD as part of Adolescents 360, a transdisciplinary initiative to increase 15- to 19-year-old girls' use of modern contraception in Nigeria, Ethiopia, and Tanzania. Youth-adult design teams (including 111 "youth designers" trained in HCD methods) undertook formative research to inform the design and implementation of interventions. We reflect on the practical implications of using instrumental strategies of HCD with a youth-led participatory approach. Our experience indicates that (1) engaging youth as project partners in transdisciplinary teams requires planned and dedicated financial and human resources; (2) involving youth as action researchers can help identify opportunities to improve program empathy and responsiveness; (3) it is difficult to recruit "extreme users" as project partners because of the high competencies needed in HCD; (4) centering empathy and employing design standards during prototyping can drive decision-making and resolve questions raised by conflicting evidence claims in existing bodies of literature; and (5) testing tangible services and products in real-world settings continues long after the intervention design phase. Youth-adult partnership should continue throughout this iterative and adaptive phase to ensure that the adolescent experience of the intervention remains at the core of intervention delivery.

RESUMEN

OBJECTIVES: Self-tests are performed and interpreted autonomously by a person without involving a healthcare professional or a certified laboratory. To gain insight into the usage of purchased HIV self-tests (HIVST) among migrants living in high-income countries, we studied the prevalence and determinants of HIVST usage among migrants living in the UK, France and the Netherlands. METHODS: We used web-based questionnaire data collected between April 2014 and July 2015 among migrants living in the UK, France and the Netherlands who participated in the cross-sectional community survey of the aMASE (advancing Migrant Access to health Services in Europe) study. HIVST usage in the preceding 12 months and the corresponding 95% CIs were calculated. Using univariate logistic regression analyses, determinants of HIVST usage were evaluated. RESULTS: Among 477 migrants living in the UK (n=235), France (n=98) and the Netherlands (n=144), HIVST usage in the preceding 12 months was 1.89% (9/477, 95% CI 0.66% to 3.11%). As all nine HIVST users were men who have sex with men (MSM), we restricted our univariate analyses to MSM (n=240). HIVST usage was borderline significantly lower among MSM living in France and the Netherlands compared with those living in the UK (UK: reference; France: OR 0.20, 95% CI 0.03 to 1.14; the Netherlands: OR 0.06, 95% CI 0.00 to 1.05). Age, region of birth, educational level, registration at a general practitioner, recent number of male sexual partners and hard drug use were not associated with HIVST usage among MSM. CONCLUSIONS: HIVST usage among migrants from the UK, France and the Netherlands was relatively low between 2014 and 2015 but higher among migrant MSM. To increase HIV testing rates among migrants, programmes need to be developed to promote HIVST among this group. Also, as more countries approve usage of HIVST, systems need to be established to ensure linkage to confirmatory testing and care following a positive test.

RESUMEN

BackgroundMen who have sex with men (MSM) are at risk of HIV and are an important population to monitor and ameliorate combination prevention efforts.AimTo estimate HIV prevalence and identify factors associated with frequent HIV testing (≥ 2 HIV tests in the last year) and pre-exposure prophylaxis (PrEP) use among MSM in London.MethodsFor this cross-sectional study, MSM recruited from 22 social venues provided oral-fluid samples for anonymous HIV antibody (Ab) testing and completed a questionnaire. Factors associated with frequent HIV testing and PrEP use were identified through logistic regression.ResultsOf 767 men recruited, 545 provided an eligible oral specimen. Among these, 38 MSM (7.0%) were anti-HIV positive including five (13.2%; 5/38) who reported their status as negative. Condomless anal sex within the previous 3 months was reported by 60.1% (412/685) men. Frequent HIV testing was associated with, in the past year, a reported sexually transmitted infection (adjusted odds ratio (AOR): 5.05; 95% confidence interval (CI): 2.66-9.58) or ≥ 2 casual condomless partners (AOR 2-4 partners: 3.65 (95% CI: 1.87-7.10); AOR 5-10 partners: 3.34(95% CI: 1.32-8.49). Age ≥ 35 years was related to less frequent HIV testing (AOR 35-44 years: 0.34 (95% CI: 0.16-0.72); AOR ≥ 45 years: 0.29 (95% CI: 0.12-0.69). PrEP use in the past year was reported by 6.2% (46/744) of MSM and associated with ≥ 2 casual condomless sex partners (AOR: 2.86; 95% CI: 1.17-6.98) or chemsex (AOR: 2.31; 95% CI: 1.09-4.91).ConclusionThis bio-behavioural study of MSM found high rates of behaviours associated with increased risk of HIV transmission. Combination prevention, including frequent HIV testing and use of PrEP, remains crucial in London.

RESUMEN

BACKGROUND: Migrant populations from countries with generalised HIV epidemics make up a significant proportion of all HIV/AIDS cases in many European Union and European Economic Area (EU/EEA) countries, with heterosexual transmission the predominant mode of HIV acquisition. While most of these infections are diagnosed for the first time in Europe, acquisition is believed to have predominantly occurred in the home country. A proportion of HIV transmission is believed to be occurring post-migration, and many countries may underestimate the degree to which this is occurring. Our objectives were to review the literature estimating the proportion of migrants believed to have acquired their HIV post-migration and examine which EU member states are able to provide estimates of probable country of HIV acquisition through current surveillance systems. METHODS: A systematic review was undertaken to gather evidence of sexual transmission of HIV within Europe among populations from countries with a generalised epidemic. In addition, national surveillance focal points from 30 EU/EEA Member States were asked to complete a questionnaire about surveillance methods and monitoring of the likely place of HIV acquisition among migrants. RESULTS & DISCUSSION: Twenty-seven papers from seven countries were included in the review and 24 countries responded to the survey. Estimates of HIV acquisition post-migration ranged from as low as 2% among sub Saharan Africans in Switzerland, to 62% among black Caribbean men who have sex with men (MSM) in the UK. Surveillance methods for monitoring post-migration acquisition varied across the region; a range of methods are used to estimate country or region of HIV acquisition, including behavioural and clinical markers. There is little published evidence addressing this issue, although Member States highlight the importance of migrant populations in their epidemics. CONCLUSIONS: There is post-migration HIV acquisition among migrants in European countries but this is difficult to quantify accurately with current data. Migrant MSM appear at particular risk of HIV acquisition post-migration. Countries that identify migrants as an important part of their HIV epidemic should focus on using an objective method for assigning probable country of HIV acquisition. Robust methods to measure HIV incidence should be considered in order to inform national prevention programming and resource allocation.

RESUMEN

INTRODUCTION: HIV transmission continues among gay and bisexual men who have sex with men (GBMSM), with those who are younger, or recent migrants, or of minority ethnicity or who are gender diverse remaining at increased risk. We aimed to identify and describe recent studies evaluating the effectiveness of HIV prevention interventions for GBMSM in high income countries. METHODS: We searched ten electronic databases for randomized controlled trials (RCTs), conducted in high income settings, and published since 2013 to update a previous systematic review (Stromdahl et al, 2015). We predefined four outcome measures of interest: 1) HIV incidence 2) STI incidence 3) condomless anal intercourse (CLAI) (or measure of CLAI) and 4) number of sexual partners. We used the National Institute for Health and Care Excellence (UK) Quality Appraisal of Intervention Studies tool to assess the quality of papers included in the review. As the trials contained a range of effect measures (e.g. odds ratio, risk difference) comparing the arms in the RCTs, we converted them into standardized effect sizes (SES) with 95% confidence intervals (CI). RESULTS: We identified 39 original papers reporting 37 studies. Five intervention types were identified: one-to-one counselling (15 papers), group interventions (7 papers), online interventions (9 papers), Contingency Management for substance use (2 papers) and Pre-exposure Prophylaxis (PrEP) (6 papers). The quality of the studies was mixed with over a third of studies rated as high quality and 11% rated as poor quality. There was some evidence that one-to-one counselling, group interventions (4-10 participants per group) and online (individual) interventions could be effective for reducing HIV transmission risk behaviours such as condomless anal intercourse. PrEP was the only intervention that was consistently effective at reducing HIV incidence. CONCLUSIONS: Our systematic review of the recent evidence that we were able to analyse indicates that PrEP is the most effective intervention for reducing HIV acquisition among GBMSM. Targeted and culturally tailored behavioural interventions for sub-populations of GBMSM vulnerable to HIV infection and other STIs should also be considered, particularly for GBMSM who cannot access or decline to use PrEP.

RESUMEN

In most HIV-positive individuals, infection time is only known to lie between the time an individual started being at risk for HIV and diagnosis time. However, a more accurate estimate of infection time is very important in certain cases. For example, one of the objectives of the Advancing Migrant Access to Health Services in Europe (aMASE) study was to determine if HIV-positive migrants, diagnosed in Europe, were infected pre- or post-migration. We propose a method to derive subject-specific estimates of unknown infection times using information from HIV biomarkers' measurements, demographic, clinical, and behavioral data. We assume that CD4 cell count (CD4) and HIV-RNA viral load trends after HIV infection follow a bivariate linear mixed model. Using post-diagnosis CD4 and viral load measurements and applying the Bayes' rule, we derived the posterior distribution of the HIV infection time, whereas the prior distribution was informed by AIDS status at diagnosis and behavioral data. Parameters of the CD4-viral load and time-to-AIDS models were estimated using data from a large study of individuals with known HIV infection times (CASCADE). Simulations showed substantial predictive ability (e.g. 84% of the infections were correctly classified as pre- or post-migration). Application to the aMASE study (n = 2009) showed that 47% of African migrants and 67% to 72% of migrants from other regions were most likely infected post-migration. Applying a Bayesian method based on bivariate modeling of CD4 and viral load, and subject-specific information, we found that the majority of HIV-positive migrants in aMASE were most likely infected after their migration to Europe.

RESUMEN

Importance: Black African adults are disproportionately affected by HIV in the United Kingdom. Many within this population acquire HIV after migration or are diagnosed late. Data are needed to inform targeted interventions to increase HIV testing and prevention in this population. Objective: To inform future HIV prevention strategies by estimating diagnosed and undiagnosed HIV infection and measuring changes in HIV testing rates in black African adults in London, United Kingdom. Design, Setting, and Participants: This cross-sectional study used a self-completed survey conducted from September 20 to December 3, 2016. Questionnaires were linked to an optional, anonymous oral fluid HIV test and compared with data from a previous survey (2004). Respondents were recruited from social and commercial venues frequented by black African adults in London. Of 2531 individuals approached in 63 venues, 752 agreed to participate. Data were analyzed initially in March 2017 (as part of internal reporting) and again in August 2018. Main Outcomes and Measures: Self-reported HIV testing within the past 5 years; diagnosed and undiagnosed HIV prevalence. Logistic regression examined factors associated with HIV testing by sex. Results: In total, 292 women (median [interquartile range] age, 31 [25.0-41.5] years) and 312 men (median [interquartile range] age, 35 [25.0-41.5] years) were included in the analysis. More than half of men (159 [51.0%]) and women (154 [52.7%]) had been tested for HIV in the past 5 years. In multivariable analysis, HIV testing was associated with a range of factors in both sexes, including health service attendance, time in the United Kingdom, and sexually transmitted infection diagnosis. Increases in HIV testing in the past 5 years were observed between 2004 and 2016 for both sexes. In the 2016 sample, 219 of 235 women (93.2%) and 206 of 228 men (90.4%) tested HIV negative. Among those testing positive, 56.3% of women (9 of 16) and 40.9% of men (9 of 22) self-reported as HIV negative or untested, indicating they were living with undiagnosed HIV. A fifth of women (20.7%) and 25.0% of men reported condomless last sex with a partner of different or unknown HIV status in the past year. Conclusions and Relevance: Despite efforts to increase HIV testing, uptake in black African communities in London remains modest. This study identified a large fraction of undiagnosed infection-greater than other at-risk populations-suggesting that the prevention and care needs of this group are not adequately met.

RESUMEN

INTRODUCTION: Migrants are overrepresented in the European HIV epidemic. We aimed to understand the barriers and facilitators to HIV testing and current treatment and healthcare needs of migrants living with HIV in Europe. METHODS: A cross-sectional study was conducted in 57 HIV clinics in nine countries (Belgium, Germany, Greece, Italy, The Netherlands, Portugal, Spain, Switzerland and United Kingdom), July 2013 to July 2015. HIV-positive patients were eligible for inclusion if they were as follows: 18 years or older; foreign-born residents and diagnosed within five years of recruitment. Questionnaires were completed electronically in one of 15 languages and linked to clinical records. Primary outcomes were access to primary care and previous negative HIV test. Data were analysed using random effects logistic regression. Outcomes of interest are presented for women, heterosexual men and gay/bisexual men. RESULTS: A total of 2093 respondents (658 women, 446 heterosexual men and 989 gay/bisexual men) were included. The prevalence of a previous negative HIV test was 46.7%, 43.4% and 82.0% for women, heterosexual and gay/bisexual men respectively. In multivariable analysis previous testing was positively associated with: receipt of post-migration antenatal care among women, permanent residency among heterosexual men and identifying as gay rather than bisexual among gay/bisexual men. Access to primary care was found to be high (>83%) in all groups and was strongly associated with country of residence. Late diagnosis was common for women and heterosexual men (60.8% and 67.1%, respectively) despite utilization of health services prior to diagnosis. Across all groups almost three-quarters of people on antiretrovirals had an HIV viral load <50 copies/mL. CONCLUSIONS: Migrants access healthcare in Europe and while many migrants had previously tested for HIV, that they went on to test positive at a later date suggests that opportunities for HIV prevention are being missed. Expansion of testing beyond sexual health and antenatal settings is still required and testing opportunities should be linked with combination prevention measures such as access to PrEP and treatment as prevention.

RESUMEN

BACKGROUND: Timely diagnosis of human immunodeficiency virus (HIV) enables access to antiretroviral treatment, which reduces mortality, morbidity and further transmission in people living with HIV. In the UK, late diagnosis among black African people persists. Novel methods to enhance HIV testing in this population are needed. OBJECTIVES: To develop a self-sampling kit (SSK) intervention to increase HIV testing among black Africans, using existing community and health-care settings (stage 1) and to assess the feasibility for a Phase III evaluation (stage 2). DESIGN: A two-stage, mixed-methods design. Stage 1 involved a systematic literature review, focus groups and interviews with key stakeholders and black Africans. Data obtained provided the theoretical base for intervention development and operationalisation. Stage 2 was a prospective, non-randomised study of a provider-initiated, HIV SSK distribution intervention targeted at black Africans. The intervention was assessed for cost-effectiveness. A process evaluation explored feasibility, acceptability and fidelity. SETTING: Twelve general practices and three community settings in London. MAIN OUTCOME MEASURE: HIV SSK return rate. RESULTS: Stage 1 - the systematic review revealed support for HIV SSKs, but with scant evidence on their use and clinical effectiveness among black Africans. Although the qualitative findings supported SSK distribution in settings already used by black Africans, concerns were raised about the complexity of the SSK and the acceptability of targeting. These findings were used to develop a theoretically informed intervention. Stage 2 - of the 349 eligible people approached, 125 (35.8%) agreed to participate. Data from 119 were included in the analysis; 54.5% (65/119) of those who took a kit returned a sample; 83.1% of tests returned were HIV negative; and 16.9% were not processed, because of insufficient samples. Process evaluation showed the time pressures of the research process to be a significant barrier to feasibility. Other major barriers were difficulties with the SSK itself and ethnic targeting in general practice settings. The convenience and privacy associated with the SSK were described as beneficial aspects, and those who used the kit mostly found the intervention to be acceptable. Research governance delays prevented implementation in Glasgow. LIMITATIONS: Owing to the study failing to recruit adequate numbers (the intended sample was 1200 participants), we were unable to evaluate the clinical effectiveness of SSKs in increasing HIV testing in black African people. No samples were reactive, so we were unable to assess pathways to confirmatory testing and linkage to care. CONCLUSIONS: Our findings indicate that, although aspects of the intervention were acceptable, ethnic targeting and the SSK itself were problematic, and scale-up of the intervention to a Phase III trial was not feasible. The preliminary economic model suggests that, for the acceptance rate and test return seen in the trial, the SSK is potentially a cost-effective way to identify new infections of HIV. FUTURE WORK: Sexual and public health services are increasingly utilising self-sampling technologies. However, alternative, user-friendly SSKs that meet user and provider preferences and UK regulatory requirements are needed, and additional research is required to understand clinical effectiveness and cost-effectiveness for black African communities. STUDY REGISTRATION: This study is registered as PROSPERO CRD42014010698 and Integrated Research Application System project identification 184223. FUNDING: The National Institute for Health Research Health Technology Assessment programme and the BHA for Equality in Health and Social Care.

RESUMEN

OBJECTIVE: We aimed to estimate the proportion of postmigration HIV acquisition among HIV-positive migrants in Europe. DESIGN: To reach HIV-positive migrants, we designed a cross-sectional study performed in HIV clinics. METHODS: The study was conducted from July 2013 to July 2015 in 57 clinics (nine European countries), targeting individuals over 18 years diagnosed in the preceding 5 years and born abroad. Electronic questionnaires supplemented with clinical data were completed in any of 15 languages. Postmigration HIV acquisition was estimated through Bayesian approaches combining extensive information on migration and patients' characteristics. CD4 cell counts and HIV-RNA trajectories from seroconversion were estimated by bivariate linear mixed models fitted to natural history data. Postmigration acquisition risk factors were investigated with weighted logistic regression. RESULTS: Of 2009 participants, 46% were MSM and a third originated from sub-Saharan Africa and Latin America & Caribbean, respectively. Median time in host countries was 8 years. Postmigration HIV acquisition was 63% (95% confidence interval: 57-67%); 72% among MSM, 58 and 51% in heterosexual men and women, respectively. Postmigration HIV acquisition was 71% for Latin America and Caribbean migrants and 45% for people from sub-Saharan Africa. Factors associated with postmigration HIV acquisition among heterosexual women and MSM were age at migration, length of stay in host country and HIV diagnosis year and among heterosexual men, length of stay in host country and HIV diagnosis year. CONCLUSION: A substantial proportion of HIV-positive migrants living in Europe acquired HIV postmigration. This has important implications for European public health policies.

RESUMEN

BACKGROUND: There is a heavy and disproportionate burden of human immunodeficiency virus (HIV) infection among migrant communities living in Europe. Despite this, the published evidence related to HIV testing, prevention, and treatment needs for migrants is sparse. OBJECTIVE: The aim of this study was to identify the factors associated with access to primary care and HIV testing among migrant groups living in Europe. METHODS: A Web-based survey (available in 14 languages) was open to all people aged 18 years and older, living outside their country of birth in the World Health Organization (WHO) European area. Community organizations in 9 countries promoted the survey to migrant groups, focusing on those at a higher risk of HIV (sub-Saharan Africans, Latin Americans, gay or bisexual men, and people who inject drugs). Multivariable analysis examined factors associated with access to primary care and previous history of an HIV test. RESULTS: In total, 559 women, 395 heterosexual men, and 674 gay or bisexual men were included in the analysis, and 68.1% (359/527) of women, 59.5% (220/371) of heterosexual men, and 89.6% (596/664) of gay or bisexual men had tested for HIV. Low perceived risk was the reason given for not testing by 62.3% (43/69) of gay or bisexual men and 83.3% (140/168) of women and heterosexual men who reported never having tested for HIV. Access to primary care was >60% in all groups. Access to primary care was strongly positively associated with living in Northern Europe compared with Southern Europe (women: adjusted odds ratio, aOR 34.56 [95% CI 11.58-101]; heterosexual men: aOR 6.93 [95% CI 2.49-19.35], and gay or bisexual men: aOR 2.53 [95% CI 1.23-5.19]), whereas those with temporary residency permits were less likely to have access to primary care (women: aOR 0.41 [95% CI 0.21-0.80] and heterosexual men: aOR 0.24 [95% CI 0.10-0.54] only). Women who had experience of forced sex (aOR 3.53 [95% CI 1.39-9.00]) or postmigration antenatal care (aOR 3.07 [95% CI 1.55-6.07]) were more likely to have tested for HIV as were heterosexual men who had access to primary care (aOR 3.13 [95% CI 1.58-6.13]) or reported "Good" health status (aOR 2.94 [95% CI 1.41-5.88]). CONCLUSIONS: Access to primary care is limited by structural determinants such as immigration and health care policy, which varies across Europe. For those migrants who can access primary care and other health services, missed opportunities for HIV testing remain a barrier to earlier testing and diagnosis for migrants in Europe. Clinicians should be aware of these potential structural barriers to HIV testing as well as low perception of HIV risk in migrant groups.

RESUMEN

BACKGROUND: Migrants form a substantial proportion of the population affected by the human immunodeficiency virus (HIV) epidemic in Europe, yet HIV prevention for this population is hindered by poor understanding of access to care and of postmigration transmission dynamics. OBJECTIVE: We present the design and methods of the advancing Migrant Access to health Services in Europe (aMASE) study, the first European cross-cultural study focused on multiple migrant populations. It aims to identify the structural, cultural, and financial barriers to HIV prevention, diagnosis, and treatment and to determine the likely country of HIV acquisition in HIV-positive migrant populations. METHODS: We delivered 2 cross-sectional electronic surveys across 10 countries (Belgium, France, Germany, Greece, Italy, the Netherlands, Portugal, Spain, Switzerland, and United Kingdom). A clinic survey aimed to recruit up to 2000 HIV-positive patients from 57 HIV clinics in 9 countries. A unique study number linked anonymized questionnaire data to clinical records data (viral loads, CD4 cell counts, viral clades, etc). This questionnaire was developed by expert panel consensus and cognitively tested, and a pilot study was carried out in 2 countries. A Web-based community survey (n=1000) reached those living with HIV but not currently accessing HIV clinics, as well as HIV-negative migrants. It was developed in close collaboration with a community advisory group (CAG) made up of representatives from community organizations in 9 of the participating countries. The CAG played a key role in data collection by promoting the survey to higher-risk migrant groups (sub-Saharan Africans, Latin Americans, men who have sex with men, and people who inject drugs). The questionnaires have considerable content overlap, allowing for comparison. Questions cover ethnicity, migration, immigration status, HIV testing and treatment, health-seeking behavior, sexual risk, and drug use. The electronic questionnaires, which were available in 15 languages, allowed for complex routing, preventing respondents from answering irrelevant questions. RESULTS: In total, we recruited 2249 participants from 57 HIV clinics as part of the clinic survey and retrieved 1637 complete responses as part of the community survey. CONCLUSIONS: The findings will provide much-needed information for improving HIV prevention interventions and access to services for migrant communities.

RESUMEN

BACKGROUND: The Sierra Leone Demographic Health Survey 2008 found an HIV prevalence of 1.5%. This study investigates associations with HIV infection and HIV testing. METHODS: Households were selected using stratified multi-stage sampling. In all selected households women aged 15-49 were eligible. In every second household men aged 15-59 were also eligible. Participants were asked to consent for anonymous HIV testing. All participants interviewed and tested were analysed. Multiple logistic regression identified associations with HIV infection, undiagnosed infection and with ever having a voluntary HIV test among sexually active participants. RESULTS: Of 7495 invited 86% (6,475) agreed to an interview and HIV test. Among 96 HIV positive participants, 78% had never taken a voluntary HIV test so were unaware of their serostatus, and 86% were sexually active in the last 12 months among whom 96% did not use a condom at last intercourse. 11% of all participants had previously voluntarily tested. Among women who had tested, 60% did so in antenatal care. We found that those living in an urban area, and those previously married, were more likely to be HIV infected. Voluntary HIV testing was more common in those aged 25-44, living in an urban area, females, having secondary or higher education, having first sexual intercourse at age 17 years or older, and using condoms at last sex. Although 82% of men and 69% of women had heard of HIV, only 35% and 29% respectively had heard of antiretroviral therapy. CONCLUSIONS: The HIV prevalence in Sierra Leone has been stable. HIV testing, however, is uncommon and most infected individuals are unaware of their serostatus. This could allow the epidemic to escalate as individuals with undiagnosed infection are unlikely to change their behaviour or access treatment. Improving knowledge and increasing testing need to remain central to HIV prevention interventions in Sierra Leone.

RESUMEN

OBJECTIVE: To identify opportunities for earlier HIV diagnosis within primary and secondary care settings in the UK in Africans with newly diagnosed HIV infection. METHODS: A survey of newly diagnosed HIV-positive Africans attending 15 HIV treatment centres across London was conducted between April 2004 and February 2006. The survey consisted of a confidential self-completed questionnaire linked to clinician-completed clinical records. RESULTS: A total of 263 questionnaires were completed, representing an uptake rate of 79.5% of patients approached and 49.8% (131/263) of participants presented with advanced HIV disease (CD4 cell count < 200 cells/mul at diagnosis). In the year prior to HIV diagnosis 76.4% (181/237) had seen their GP, 38.3% (98/256) had attended outpatient services, and 15.2% (39/257) inpatient services, representing missed opportunities for earlier HIV diagnosis. Of those attending GP services the issue of HIV and/or HIV testing was raised for 17.6% (31/176) and 37.1% (78/210) had a previous negative HIV test, 32.5% of these within the UK. Medical attention was sought for wide ranging reasons, often not obviously connected to underlying HIV status. Despite the population predominantly coming from countries of high HIV prevalence personal appreciation of risk was comparatively low and knowledge of benefits of testing lacking. CONCLUSION: Africans are accessing health services but clinicians are failing to use these opportunities effectively for preventive and diagnostic purposes with regards to HIV infection. Comparatively low appreciation of personal risk and lack of perceived ill health within this community means clinicians need to be more proactive in addressing HIV.
