Abstract
Indicator condition (IC)-guided HIV testing, i.e., testing when diagnosing a condition associated with HIV, is a feasible and cost-effective testing strategy to identify undiagnosed individuals. Assessing determinants for IC-guided testing may identify opportunities for improvement. A survey study based on the Theory of Planned Behaviour (TPB) was conducted among 163 hospital physicians from five specialties in Amsterdam, the Netherlands. Structural equation models were used to determine the association between the TPB domains (i.e., attitude, belief, norms, self-efficacy and behavioural control) and (1) the intention to test as a mediator for HIV testing behaviour (intentional model) and (2) actual HIV testing behaviour (direct model). Both models accounted for the effect of guideline recommendations. Behaviour scored lower than intention on a five-point scale (mean score of 2.8, SD = 1.6 versus 3.8, SD = 1.1; p<0.0001). The direct model had a better fit than the intentional model based on fit statistics. Discrepancies between the determinants most important for intention versus those for behaviour led to the following recommendations: interventions to improve IC-guided testing in hospitals should primarily focus on implementation of guideline recommendations, followed by improving physicians' attitude towards IC-guided HIV testing and self-efficacy, as these were the most important correlates of actual HIV testing behaviour.

Lee CY, Lin YP, Lin CY, Lu PL, Liang FW. Enhancing indicator condition-guided HIV testing in Taiwan: a nationwide case-control study from 2009 to 2015. BMC Public Health 2024; 24:967. [PMID: 38580963 PMCID: PMC10998297 DOI: 10.1186/s12889-024-18499-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Accepted: 04/02/2024] [Indexed: 04/07/2024] Open
Abstract
BACKGROUND Although indicator condition (IC)-guided HIV testing (IC-HIVT) is effective at facilitating timely HIV diagnosis, research on IC categories and the related HIV risk in Taiwan is limited. To improve the adoption and spread of IC-HIVT in Taiwan, this study compared the IC categories of people living with HIV (PLWH) and non-HIV controls and investigated delays in the diagnosis of HIV infection. METHODS This nationwide, retrospective, 1:10-matched case-control study analyzed data from the Notifiable Diseases Surveillance System and National Health Insurance Research Database to evaluate 42 ICs for the 5-year period preceding a matched HIV diagnostic date from 2009 to 2015. The ICs were divided into category 1 ICs (AIDS-defining opportunistic illnesses [AOIs]), category 2 ICs (diseases associated with impaired immunity or malignancy but not AOIs), category 3 ICs (ICs associated with sexual behaviors), and category 4 ICs (mononucleosis or mononucleosis-like syndrome). Logistic regression was used to evaluate the HIV risk associated with each IC category (at the overall and annual levels) before the index date. Wilcoxon rank-sum test was performed to assess changes in diagnostic delays following an incident IC category by HIV transmission routes. RESULTS Fourteen thousand three hundred forty-seven PLWH were matched with 143,470 non-HIV controls. The prevalence results for all ICs and category 1-4 ICs were, respectively, 42.59%, 11.16%, 15.68%, 26.48%, and 0.97% among PLWH and 8.73%, 1.05%, 4.53%, 3.69%, and 0.02% among non-HIV controls (all P < 0.001). Each IC category posed a significantly higher risk of HIV infection overall and annually. The median (interquartile range) potential delay in HIV diagnosis was 15 (7-44), 324.5 (36-947), 234 (13-976), and 74 (33-476) days for category 1-4 ICs, respectively. Except for category 1 for men who have sex with men, these values remained stable across 2009-2015, regardless of the HIV transmission route. CONCLUSIONS Given the ongoing HIV diagnostic delay, IC-HIVT should be upgraded and adapted to each IC category to enhance early HIV diagnosis.

The roles of the general practitioner and sexual health centre in HIV testing: comparative insights and impact on HIV incidence rates in the Rotterdam area, the Netherlands - a cross-sectional population-based study. BMC Public Health 2023; 23:2553. [PMID: 38129840 PMCID: PMC10734097 DOI: 10.1186/s12889-023-17483-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Accepted: 12/14/2023] [Indexed: 12/23/2023] Open
Abstract
BACKGROUND Access to HIV testing is crucial for detection, linkage to treatment, and prevention. In less urbanised areas, reliance on general practitioners (GPs) for HIV testing is probable, as sexual health centres (SHC) are mostly located within urbanised areas. Limited insight into individuals undergoing HIV testing stems from sparse standard registration of demographics at GPs. This cross-sectional study aims (1) to assess and compare HIV testing at the GP and SHC, and (2) to assess population- and provider-specific HIV incidence. METHODS Individual HIV testing data of GPs and SHC were linked to population register data (aged ≥ 15 years, Rotterdam area, 2015-2019). We reported the proportion HIV tested, and compared GP and SHC testing rates with negative binomial generalised additive models. Data on new HIV diagnoses (2015-2019) from the Dutch HIV Monitoring Foundation relative to the population were used to assess HIV incidence. RESULTS The overall proportion HIV tested was 1.14% for all residents, ranging from 0.41% for ≥ 40-year-olds to 4.70% for Antilleans. The GP testing rate was generally higher than the SHC testing rate with an overall rate ratio (RR) of 1.61 (95% CI: 1.56-1.65), but not for 15-24-year-olds (RR: 0.81, 95% CI: 0.74-0.88). Large differences in HIV testing rate (1.36 to 39.47 per 1,000 residents) and GP-SHC ratio (RR: 0.23 to 7.24) by geographical area were observed. The GPs' contribution in HIV testing was greater for GP in areas further away from the SHC. In general, population groups that are relatively often tested are also the groups with most diagnoses and highest incidence (e.g., men who have sex with men, non-western). The overall incidence was 10.55 per 100,000 residents, varying from 3.09 for heterosexual men/women to 24.04 for 25-29-year-olds. CONCLUSIONS GPs have a pivotal role in HIV testing in less urbanised areas further away from the SHC, and among some population groups. A relatively high incidence often follows relatively high testing rates. Opportunities to improve HIV testing have been found for migrants, lower-educated individuals, in areas less urbanised areas and further away from GP/SHC. Strategies include additional targeted testing, via for example SHC branch locations and outreach activities.

Abstract
INTRODUCTION Around 40% of estimated people with HIV infection remain undiagnosed globally. In Ethiopia, only 72% of people with HIV know their status. This study aims to assess the proportion and the factors associated with partner and family-based index case HIV testing in Woliso Town. METHODS A facility-based cross-sectional study was conducted among 346 people currently on ART. Data were entered into Epi Info™ 7.2.3.1 and analyzed using SPSS 21. Significance of odds ratios was determined with 95% CI and p < 0.05. RESULTS Among 345 study participants, 333 (96.5%) with 95% CI (94.5-98.3) index cases have families tested for HIV. The odds of HIV testing were 7.22 times higher among those who disclosed their HIV status (AOR = 7.22 95% CI: 1.45, 35.82) compared to those who did not disclose. Those who stayed <12 months on ARTwere 87% less likely to have tested families (AOR = 0.13 95% CI: 0.03, 0.63) compared to those who stayed ≥12 months on ART. CONCLUSION Higher proportions of index cases have tested families. Partner and family-based index case HIV testing has association with HIV status disclosure and duration the index cases stayed on ART. The platform of partner and family-based index case HIV testing should be sustained through strengthening disclosure counseling.

Missed opportunities for HIV testing among those who accessed sexually transmitted infection (STI) services, tested for STIs and diagnosed with STIs: a systematic review and meta-analysis. J Int AIDS Soc 2023; 26:e26049.

Abstract
INTRODUCTION Of 37.7 million people living with HIV in 2020, 6.1 million still do not know their HIV status. We synthesize evidence on concurrent HIV testing among people who tested for other sexually transmitted infections (STIs). METHODS We conducted a systematic review using five databases, HIV conferences and clinical trial registries. We included publications between 2010 and May 2021 that reported primary data on concurrent HIV/STI testing. We conducted a random-effects meta-analysis and meta-regression of the pooled proportion for concurrent HIV/STI testing. RESULTS We identified 96 eligible studies. Among those, 49 studies had relevant data for a meta-analysis. The remaining studies provided data on the acceptability, feasibility, barriers, facilitators, economic evaluation and social harms of concurrent HIV/STI testing. The pooled proportion of people tested for HIV among those attending an STI service (n = 18 studies) was 71.0% (95% confidence intervals: 61.0-80.1, I2 = 99.9%), people tested for HIV among those who were tested for STIs (n = 15) was 61.3% (53.9-68.4, I2 = 99.9%), people tested for HIV among those who were diagnosed with an STI (n = 13) was 35.3% (27.1-43.9, I2 = 99.9%) and people tested for HIV among those presenting with STI symptoms (n = 3) was 27.1% (20.5-34.3, I2 = 92.0%). The meta-regression analysis found that heterogeneity was driven mainly by identity as a sexual and gender minority, the latest year of study, country-income level and region of the world. DISCUSSION This review found poor concurrent HIV/STI testing among those already diagnosed with an STI (35.3%) or who had symptoms with STIs (27.1%). Additionally, concurrent HIV/STI testing among those tested for STIs varied significantly according to the testing location, country income level and region of the world. A few potential reasons for these observations include differences in national STI-related policies, lack of standard operation procedures, clinician-level factors, poor awareness and adherence to HIV indicator condition-guided HIV testing and stigma associated with HIV compared to other curable STIs. CONCLUSIONS Not testing for HIV among people using STI services presents a significant missed opportunity, particularly among those diagnosed with an STI. Stronger integration of HIV and STI services is urgently needed to improve prevention, early diagnosis and linkage to care services.

Improving provider-initiated testing for HIV and other STI in the primary care setting in Amsterdam, the Netherlands: Results from a multifaceted, educational intervention programme. PLoS One 2023; 18:e0282607. [PMID: 36877664 PMCID: PMC9987818 DOI: 10.1371/journal.pone.0282607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Accepted: 02/18/2023] [Indexed: 03/07/2023] Open
Abstract
BACKGROUND In the Netherlands, general practitioners (GPs) play a key role in HIV testing. However, the proportion of people diagnosed with late-stage HIV remains high, and opportunities for earlier diagnosis are being missed. We implemented an educational intervention to improve HIV and STI testing in primary care in Amsterdam, the Netherlands. METHODS GPs were invited to participate in an educational program between 2015 and 2020, which included repeat sessions using audit and feedback and quality improvement plans. Data on HIV, chlamydia and gonorrhoea testing by GPs were collected from 2011 through 2020. The primary outcome was HIV testing frequency, which was compared between GPs before and after participation using Poisson regression. Secondary outcomes were chlamydia and gonorrhoea testing frequencies, and positive test proportions. Additional analyses stratified by patient sex and age were done. FINDINGS GPs after participation performed 7% more HIV tests compared to GPs before participation (adjusted relative ratio [aRR] 1.07, 95%CI 1.04-1.09); there was no change in the proportion HIV positive tests (aRR 0.87, 95%CI 0.63-1.19). HIV testing increased most among patients who were female and ≤19 or 50-64 years old. After participation, HIV testing continued to increase (aRR 1.02 per quarter, 95%CI 1.01-1.02). Chlamydia testing by GPs after participation increased by 6% (aRR 1.06, 95%CI 1.05-1.08), while gonorrhoea testing decreased by 2% (aRR 0.98, 95%CI 0.97-0.99). We observed increases specifically in extragenital chlamydia and gonorrhoea testing. CONCLUSIONS The intervention was associated with a modest increase in HIV testing among GPs after participation, while the proportion positive HIV tests remained stable. Our results suggest that the intervention yielded a sustained effect.

Infect Dis Ther 2022; 11:1033-1056. [PMID: 35301666 PMCID: PMC9124249 DOI: 10.1007/s40121-022-00619-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Accepted: 03/02/2022] [Indexed: 12/24/2022] Open
Abstract
INTRODUCTION Late initiation (LI) of combination antiretroviral therapy (cART)-defined as having a CD4+ count of < 200 cells/μL or an AIDS-defining disease at cART initiation-has detrimental outcomes but remains prevalent worldwide, with LI trends and etiologies following the implementation of various HIV policies remaining underinvestigated. We assessed key concerns, characterized the determinants of various statuses at cART initiation, and evaluated the effects of those statuses on all-cause mortality after cART initiation. METHODS This multicenter retrospective cohort study enrolled 1198 patients with newly diagnosed HIV infection during 2009-2019 who were grouped by status at cART initiation: those without LI (non-LI group, 56.01%); those with LI but without late presentation (LP) of HIV (LP: a CD4 + count of < 200 cells/μL at HIV presentation or AIDS events ≤ 3 months of HIV diagnosis) [LILP(-) group, 4.51%]; and those with LI and with LP of HIV [LILP(+) group, 39.48%]. Joinpoint regression was used to identify changes in LI proportion. RESULTS The median CD4+ count at cART initiation increased significantly between 2009 (98 cells/μL) and 2015 (325 cells/μL) and stabilized thereafter (P for trend < 0.001). For LI, we identified one joinpoint in 2015: a substantial decrease from 77.14% in 2009 to 34.45% in 2015, followed by a nonsignificant increase to 39.1% in 2019. Overall, LILP(+) explained 89.8% of LI, without significant changes (92.59% in 2009 to 94.23% in 2019). In addition to HIV diagnosis during 2009-2012, multinomial logistic regression identified an age over 30 years and acute HIV infection as risk factors for LILP(+) and LILP(-), respectively. LILP(-) and LILP(+) were associated with a higher all-cause mortality risk. CONCLUSION Given the rise in LI from 2015 in the era of treat-all and rapid cART initiation, strategic interventions to increase earlier cART initiation must be intensified in Taiwan, especially among populations with delayed access to HIV testing services.

Abstract
BACKGROUND In Australia, one-third of human immunodeficiency virus (HIV) diagnoses occur late, with an estimated 11% of people with HIV unaware of their diagnosis. Undiagnosed and untreated HIV infection increases morbidity in the HIV positive person and allows onward transmission of HIV. AIM To determine the rate of HIV testing in acute general medicine patients with HIV indicator conditions (IC) and evaluate the effectiveness of an educational intervention in improving testing rates. METHODS Single-centre, tertiary hospital, before-after study of general medicine inpatients with IC for 12 weeks prior and 10 weeks post an educational intervention focusing on recommendations for HIV testing including IC. The REASON Cohort Discovery Tool was used to search for the IC using ICD-10 codes and laboratory data. The presence of IC was estimated, and HIV testing rates before and after the intervention were compared. Regression analysis was utilised to identify characteristics associated with HIV testing. RESULTS Of 1414 admissions in the baseline period and 946 in the post-period, 161 (11.4%) and 132 (14.0%) had at least one IC present respectively. There were 18 (11.2%) HIV tests performed for admissions with IC in the pre-period which increased to 27 (20.5%) (P = 0.028) in the post-period. Younger patients were more likely to be tested and regression analysis identified the educational intervention (adjusted odds ratio) 2.2 (1.1, 4.4) to be significantly associated with testing. CONCLUSIONS Although HIV testing rates for IC doubled following the intervention, they remained unacceptably low. The recently introduced electronic medical record presents opportunities to prompt HIV testing.

Monitoring Recently Acquired HIV Infections in Amsterdam, The Netherlands: The Attribution of Test Locations. FRONTIERS IN REPRODUCTIVE HEALTH 2021; 3:568611. [PMID: 36304001 PMCID: PMC9580630 DOI: 10.3389/frph.2021.568611] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2020] [Accepted: 01/19/2021] [Indexed: 11/13/2022] Open
Abstract
Background: Surveillance of recent HIV infections (RHI) using an avidity assay has been implemented at Dutch sexual health centres (SHC) since 2014, but data on RHI diagnosed at other test locations is lacking. Setting: Implementation of the avidity assay in HIV treatment clinics for the purpose of studying RHI among HIV patients tested at different test locations. Methods: We retrospectively tested leftover specimens from newly diagnosed HIV patients in care in 2013–2015 in Amsterdam. Avidity Index (AI) values ≤0.80 indicated recent infection (acquired ≤6 months prior to diagnosis), and AI > 0.80 indicated established infection (acquired >6 months prior to diagnosis). An algorithm for RHI was applied to correct for false recency. Recency based on this algorithm was compared with recency based on epidemiological data only. Multivariable logistic regression analysis was used to identify factors associated with RHI among men who have sex with men (MSM). Results: We tested 447 specimens with avidity; 72% from MSM. Proportions of RHI were 20% among MSM and 10% among heterosexuals. SHC showed highest proportions of RHI (27%), followed by GPs (15%), hospitals (5%), and other/unknown locations (11%) (p < 0.001). Test location was the only factor associated with RHI among MSM. A higher proportion of RHI was found based on epidemiological data compared to avidity testing combined with the RHI algorithm. Conclusion: SHC identify more RHI infections compared to other test locations, as they serve high-risk populations and offer frequent HIV testing. Using avidity-testing for surveillance purposes may help targeting prevention programs, but the assay lacks robustness and its added value may decline with improved, repeat HIV testing and data collection.

Abstract
Background Development of additional diagnostic strategies for earlier HIV diagnosis are needed as approximately 50% of newly diagnosed HIV-infected individuals continue to present late for HIV care. Aim We aimed to analyse antimicrobial consumption in the 3 years preceding HIV diagnosis, assess whether there was a higher consumption in those diagnosed with HIV compared with matched controls and whether the level of consumption was associated with the risk of HIV infection. Methods We conducted a nested case–control study, identifying all individuals (n = 2,784 cases) diagnosed with HIV in Denmark from 1998 to 2016 and 13 age-and sex-matched population controls per case (n = 36,192 controls) from national registers. Antimicrobial drug consumption was estimated as defined daily doses per person-year. We used conditional logistic regression to compute odds ratios and 95% confidence intervals. Results In the 3 years preceding an HIV diagnosis, we observed more frequent and higher consumption of antimicrobial drugs in cases compared with controls, with 72.4% vs 46.3% having had at least one prescription (p < 0.001). For all antimicrobial classes, the association between consumption and risk of subsequent HIV diagnosis was statistically significant (p < 0.01). The association was stronger with higher consumption and with shorter time to HIV diagnosis. Conclusion HIV-infected individuals have a significantly higher use of antimicrobial drugs in the 3 years preceding HIV diagnosis than controls. Prescription of antimicrobial drugs in primary healthcare could be an opportunity to consider proactive HIV testing. Further studies need to identify optimal prescription cut-offs that could endorse its inclusion in public health policies.

Abstract
BACKGROUND Late diagnoses are still a cause of increased HIV-related morbidity and mortality despite the availability of highly effective treatments. The aim of this study was to identify indicator conditions (ICs) in late presenters with HIV infection (LPs) that may represent missed opportunities of undertaking earlier HIV testing. METHODS The medical records of LPs referred to a specialist clinic in Milan, Italy, between 2011 and 2017 were reviewed to assess the frequency of ICs during the five years preceding diagnosis. Logistic regression analysis was used to investigate the factors associated with missed opportunities of making an earlier diagnosis. RESULTS The analysis considered 203 LPs (60.6% of the patients newly diagnosed as having HIV infection during the study period). Most had had ≥1 medical encounter in the five years before diagnosis, and 54 (26.6%) had been diagnosed as having ≥1 IC without undergoing HIV testing. The most frequent ICs were herpes zoster (19.8%), constitutional symptoms (17.4%) and lympho/thrombocytopenia (12.8%), and the missed opportunities for testing occurred in the settings of primary care (44.9%), specialist medical (38.2%) or surgical services (11.3%), and emergency departments (5.6%). Twenty-five (53.2%) of the 47 subjects with a non AIDS-defining IC had AIDS at the time of the diagnosis of HIV infection. Subjects aged >60 years were at increased risk of missed diagnostic opportunities (aOR 4.80, p = 0.008). CONCLUSION Implementing IC-guided HIV testing in non-specialist settings is an essential means of reducing late diagnoses of HIV infection even in the case of older subjects.

Abstract
BACKGROUND Late HIV diagnosis is detrimental both to the individual and to society. Strategies to improve early diagnosis of HIV must be a key health care priority. We examined whether nation-wide electronic registry data could be used to predict HIV status using machine learning algorithms. METHODS We extracted individual level data from Danish registries and used algorithms to predict HIV status. We used various algorithms to train prediction models and validated these models. We calibrated the models to mimic different clinical scenarios and created confusion matrices based on the calibrated models. FINDINGS A total 4,384,178 individuals, including 4,350 with incident HIV, were included in the analyses. The full model that included all variables that included demographic variables and information on past medical history had the highest area under the receiver operating characteristics curves of 88·4% (95%CI: 87·5% - 89·4%) in the validation dataset. Performance measures did not differ substantially with regards to which machine learning algorithm was used. When we calibrated the models to a specificity of 99·9% (pre-exposure prophylaxis (PrEP) scenario), we found a positive predictive value (PPV) of 8·3% in the full model. When we calibrated the models to a sensitivity of 90% (screening scenario), 384 individuals would have to be tested to find one undiagnosed person with HIV. INTERPRETATION Machine learning algorithms can learn from electronic registry data and help to predict HIV status with a fairly high level of accuracy. Integration of prediction models into clinical software systems may complement existing strategies such as indicator condition-guided HIV testing and prove useful for identifying individuals suitable for PrEP. FUNDING The study was supported by funds from the Preben and Anne Simonsens Foundation, the Novo Nordisk Foundation, Rigshospitalet, Copenhagen University, the Danish AIDS Foundation, the Augustinus Foundation and the Danish Health Foundation.

Abstract
OBJECTIVES To estimate trends in HIV testing, positivity and prevalence in UK primary care for 2000-2015 as part of a wider investigation into reasons for late diagnosis of HIV. DESIGN Retrospective cohort study using the Clinical Practice Research Datalink (CPRD) which is derived from computerised clinical records produced during consultations in primary care. SETTING 404 general practices in England. PARTICIPANTS 5 979 598 adults aged ≥16 years registered between 2000 and 2015 with 45 093 761 person years of observation. OUTCOMES Annual HIV testing rates, proportion of positive tests and prevalence of HIV-infected people recorded in primary care 2000-2015. RESULTS HIV testing in primary care increased from 2000 to 2010, but then declined. Testing was higher in females than in males and in those aged 16-44 years compared with older adults. Rates per 100 000 in women aged 16-44 years were 177 (95% CI 167 to 188); 1309 (95% CI 1282 to 1336); 1789 (95% CI 1757 to 1821) and 839 (95% CI 817 to 862) in 2000, 2005, 2010 and 2015, respectively, and for non-pregnant women: 22.5 (95% CI 19 to 26); 134 (95% CI 125 to 143); 262 (95% CI 250 to 275); 190 (95% CI 179 to 201). For men aged 16-44 years rates were: 26 (95% CI 22 to 29); 107 (95% CI 100 to 115); 196 (95% CI 185 to 206); 137 (95% CI 127 to 146). Over the study period, there were approximately two positive results per 1000 HIV tests. Men were eightfold more likely to test positive than women. The percentage of HIV diagnoses among adults recorded in CPRD may be as low as 55% in London and 67% in the rest of the UK. CONCLUSIONS HIV testing rates in primary care peaked in 2010 and subsequently declined. Access to testing was higher for women despite the prevalence of HIV being higher in men. IMPLICATIONS AND FURTHER RESEARCH NEEDED Opportunities remain in primary care for increasing HIV testing to prevent costly late diagnoses and decrease HIV transmission. Interventions to improve targeting of tests and increase adherence to HIV testing guidelines are needed in primary care.

Abstract
BACKGROUND Late HIV diagnosis is associated with increased AIDS-related morbidity and mortality as well as an increased risk of HIV transmission. In this study, we quantified and characterized missed opportunities for earlier HIV diagnosis in British Columbia (BC), Canada. DESIGN Retrospective cohort. METHODS A missed opportunity was defined as a healthcare encounter due to a clinical manifestation which may be caused by HIV infection, or is frequently present among those with HIV infection, but no HIV diagnosis followed within 30 days. We developed an algorithm to identify missed opportunities within one, three, and five years prior to diagnosis. The algorithm was applied to the BC STOP HIV/AIDS population-based cohort. Eligible individuals were ≥18 years old, and diagnosed from 2001-2014. Multivariable logistic regression identified factors associated with missed opportunities. RESULTS Of 2119 individuals, 7%, 12% and 14% had ≥1 missed opportunity during one, three and five years prior to HIV diagnosis, respectively. In all analyses, individuals aged ≥40 years, heterosexuals or people who ever injected drugs, and those residing in Northern health authority had increased odds of experiencing ≥1 missed opportunity. In the three and five-year analysis, individuals with a CD4 count <350 cells/mm3 were at higher odds of experiencing ≥1 missed opportunity. Prominent missed opportunities were related to recurrent pneumonia, herpes zoster/shingles among younger individuals, and anemia related to nutritional deficiencies or unspecified cause. CONCLUSIONS Based on our newly-developed algorithm, this study demonstrated that HIV-diagnosed individuals in BC have experienced several missed opportunities for earlier diagnosis. Specific clinical indicator conditions and population sub-groups at increased risk of experiencing these missed opportunities were identified. Further work is required in order to validate the utility of this proposed algorithm by establishing the sensitivity, specificity, positive and negative predictive values corresponding to the incidence of the clinical indicator conditions among both HIV-diagnosed and HIV-negative populations.

Abstract
Background Treatment as prevention approaches for HIV require optimal HIV testing strategies to reduce undiagnosed HIV infections. In most settings, HIV testing strategies still result in unacceptably high rates of missed and late diagnoses. This study aimed to identify clinical opportunities for targeted HIV testing in persons at risk to facilitate earlier HIV diagnosis in New South Wales, Australia; and to assess the duration between the diagnosis of specific conditions and HIV diagnosis. Methods The Australian National HIV registry was linked to cancer diagnoses, notifiable condition diagnoses, emergency department presentations and hospital admissions for all HIV diagnoses between 1993 and 2012 in NSW. Date of HIV acquisition was estimated from back-projection models and people with a likely duration from infection to diagnosis of less than 180 days were excluded. Risk factors associated with clinical opportunities for the earlier diagnosis of HIV were identified. Results Sexually transmitted infection diagnoses (particularly gonorrhoea and syphilis) and some hospital admissions (mental health and drug-related diagnoses, and non-infective digestive disorder diagnoses) were prominent among people estimated to be living with undiagnosed HIV. The length of time between a clinical opportunity for the earlier HIV diagnosis and actual HIV diagnosis was 13.3 months for notifiable conditions, and 15.2 months for hospital admissions. People with lower CD4+ cell count at diagnosis, and older people were significantly less likely to have a missed opportunity for earlier HIV diagnosis. Conclusions Additional targeted clinical HIV testing strategies are warranted for people with gonorrhoea and syphilis; and hospital presentations or admissions for mental health, drug-related and gastrointestinal diagnoses.

Abstract
BACKGROUND Late diagnosis of HIV infection remains a key challenge in Europe. It is acknowledged that general practitioners (GPs) may contribute greatly to early case finding, yet there is evidence that many diagnostic opportunities are being missed. To further promote HIV testing in primary care and to increase the utility of available research, the existing evidence has been synthesised in a systematic review adhering to the PRISMA guidelines. METHODS The databases PubMed, Scopus and Embase were searched for the period 2006-2017. Two authors judged independently on the eligibility of studies. Through a mixed-methods systematic review of 29 studies, we provide a description of HIV testing in general practices in Europe, including barriers and facilitators. RESULTS The findings of the study show that although various approaches to target patients are used by GPs, most tests are still carried out based on the patient's request. Several barriers obstruct HIV testing in general practice. Included are a lack of communication skills on sexual health, lack of knowledge about HIV testing recommendations and epidemic specificities, difficulties with using the complete list of clinical HIV indicator diseases and lack of experience in delivering and communicating test results. The findings also suggest that the provision of specific training, practical tools and promotion programmes has an impact on the testing performance of GPs. CONCLUSIONS GPs could have an increased role in provider-initiated HIV-testing for early case finding. To achieve this objective, solutions to the reported barriers should be identified and testing criteria adapted to primary healthcare defined. Providing guidance and training to better identify priority groups for HIV testing, as well as information on the HIV epidemic's characteristics, will be fundamental to increasing awareness and testing by GPs.

Abstract
We evaluated Amsterdam HIV Testing Week (HTW) 2016 regarding its primary goals of raising awareness and prompting HIV testing. Participating services offered free, anonymous HIV testing, with a focus on reaching men who have sex with men (MSM) and people with a non-western migration background. Sociodemographic characteristics, HIV testing history, intention to test regularly, beliefs about personal risk and severity of HIV, and perceived social norms regarding HIV testing and people living with HIV were assessed among all who tested. A community quick scan assessed awareness of Amsterdam HTW 2016 and attitudes and intentions regarding HIV testing. Of 806 people tested, 59.6% (405/679) belonged to key populations. None tested HIV-positive and 37.6% intended to test regularly in the future. The community quick scan found moderate awareness of Amsterdam HTW 2016. Awareness was highest among recent testers and HIV-positive MSM and not associated with HIV testing attitudes and intentions. People tested during Amsterdam HTW 2016 were from key populations and/or were not (adequately) reached via traditional testing approaches. The contribution of the Amsterdam HTW approach to raising awareness and prompting HIV testing in key populations may benefit from focusing on HIV-negative individuals who have not been tested recently.

Abstract
INTRODUCTION Late Diagnosis (LD) of Human Immunodeficiency Virus (HIV) infection (CD4 lymphocytes <350/μl at diagnosis of the disease), deteriorates the condition of those affected and increases the probability of transmission. The objective of the present study was to analyse the prevalence of LD, to identify missed diagnostic opportunities (MDO) and to find out which level of the health care delivery system they took place. METHODS Retrospective, observational and descriptive study of the population diagnosed with infection of HIV/AIDS in the period 2011-2015 in Aragon. MDO were identified during the 3 years prior to diagnosis of the disease in all levels of the health care delivery system as well as frequentation of consultations. The indicator conditions (IC) that generated more MDO were analysed according to the latest recommendations for early diagnosis of HIV in the health care setting. RESULTS 435 newly diagnosed HIV/AIDS cases were analysed. 45.1% were diagnosed in Primary Healthcare (PH). 49.4% presented criteria of LD and 61.1% were infected through heterosexual contact. The majority of MDO (68.5%) were given in PH. The IC that generated the most MDO were seborrheic dermatitis/exanthema (19.4%) and fever of unknown origin (10.3%). However, the IC that were associated with higher LD were pneumonia acquired in the community and unjustified weight loss. CONCLUSION In Aragon, prevalence of LD is high, the main route of infection is heterosexual and most of MDO go unnoticed in PH. The dissemination of current guidelines for requesting IC guided HIV testing and HIV screening across the preoperative period will result in an effective measure to decrease the LD.
