Hospital-based routine HIV testing in high-income countries: a systematic literature review

Missed Opportunities in HIV Testing in Turkiye: Implications for Late Diagnoses

BACKGROUND

Late diagnosis of HIV infection is a major global problem. In Turkiye, only 41%-50% of people living with HIV are diagnosed, suggesting that many opportunities for HIV testing might be missed.

SETTING

The aim of this study was to determine the missed testing opportunities for HIV in healthcare settings in Turkiye and the predictors for missed opportunities (MOs).

METHODS

The study included patients with a new HIV diagnosis, presenting to care between January 2018 and December 2020. They were given a verbal questionnaire face to face, by a telephone call or an online meeting for visits to a health care setting within the year before their diagnosis. Electronic medical records were also examined.

RESULTS

The sample included 198 patients with at least 1 visit to any health care setting, with a total of 1677 visits. Patients had an indication for HIV testing in 51.3% (861/1677) of the visits; an HIV test was not offered in 77.9% (671/861) and was considered a MO. The highest number of MOs was in emergency departments (59.8%) (180/301). The most common reason for visiting was constitutional symptoms and indicator conditions (55.4%) (929/1677). University graduates and those with a CD4+ T-cell count <200/mm 3 were more likely to have a MO.

CONCLUSIONS

Many opportunities to diagnose HIV at an early stage are missed in health care settings in Turkiye. Considering the rapidly increasing number of new diagnoses in the last decade, urgent action needs to be taken.

What is added by this report?

This study found that, following the implementation of routine HIV screening in hospitals in Xishuangbanna Prefecture, Yunnan Province, there was a significant increase in the number of HIV screenings, positive results, and the positive rate of HIV screening in primary-level hospitals.

What are the implications for public health practice?

Routine hospital-based HIV screening is effective in identifying HIV infections in areas with concentrated epidemics.

National medical specialty guidelines of HIV indicator conditions in Europe lack adequate HIV testing recommendations: a systematic guideline review

BackgroundAdequate identification and testing of people at risk for HIV is fundamental for the HIV care continuum. A key strategy to improve timely testing is HIV indicator condition (IC) guided testing.AimTo evaluate the uptake of HIV testing recommendations in HIV IC-specific guidelines in European countries.MethodsBetween 2019 and 2021, European HIV experts reviewed guideline databases to identify all national guidelines of 62 HIV ICs. The proportion of HIV IC guidelines recommending HIV testing was reported, stratified by subgroup (HIV IC, country, eastern/western Europe, achievement of 90-90-90 goals and medical specialty).ResultsOf 30 invited European countries, 15 participated. A total of 791 HIV IC guidelines were identified: median 47 (IQR: 38-68) per country. Association with HIV was reported in 69% (545/791) of the guidelines, and 46% (366/791) recommended HIV testing, while 42% (101/242) of the AIDS-defining conditions recommended HIV testing. HIV testing recommendations were observed more frequently in guidelines in eastern (53%) than western (42%) European countries and in countries yet to achieve the 90-90-90 goals (52%) compared to those that had (38%). The medical specialties internal medicine, neurology/neurosurgery, ophthalmology, pulmonology and gynaecology/obstetrics had an HIV testing recommendation uptake below the 46% average. None of the 62 HIV ICs, countries or medical specialties had 100% accurate testing recommendation coverage in all their available HIV IC guidelines.ConclusionFewer than half the HIV IC guidelines recommended HIV testing. This signals an insufficient adoption of this recommendation in non-HIV specialty guidelines across Europe.

High-level compliance to opt-out HIV testing in the emergency department (ED) of a large teaching hospital using the biochemistry sample as the sample type for HIV screening

INTRODUCTION

HIV remains a key public health issue. National Institute for Health and Care Excellence and British HIV Association guidance recommends that patients should be offered HIV testing when admitted to hospital or attending emergency departments (EDs) in areas with a prevalence ≥ 2 per 1000. We report a novel method of testing and the first 3-year results from our HIV ED testing programme utilizing biochemistry samples for HIV testing, with the aim of improving uptake while ensuring no changes to clinical practice in EDs.

METHODS

Routine ED HIV testing was implemented on 1 October 2018; it was initially opt-in and was subsequently changed to opt-out on 1 February 2019. HIV testing was added to all ED blood test order sets and was performed on the biochemistry samples of those aged 18-59 years. The age range was extended to include those aged 16+ years on 1 March 2021 along with a move to notional consent.

RESULTS

A total of 78 333 HIV tests were performed from an estimated 110 683 attendees who had bloods taken in the same age range, demonstrating an overall 69.5% testing coverage. On implementation of opt-out testing after the first 4 months, the proportion of tests increased (from 57.9% to 69%). After increase in age range to 16+ years and a move to notional consent, the overall testing coverage improved to 74.2%. Of 1054 reactive results, 728 (69%) were known people living with HIV, eight (0.8%) were not contactable, two (0.2%) re-tested elsewhere and three (0.3%) declined a re-test. A total of 259 false-positives were determined by follow-up testing and 50 (4.8%) were newly diagnosed with HIV. An HIV diagnosis was suspected in only 22%, and 48% had never previously tested for HIV.

CONCLUSIONS

An opt-out HIV testing programme with notional consent and using biochemistry samples within the ED is feasible, acceptable and provides an excellent opportunity to diagnose patients who do not perceive themselves to be at risk or have never tested before.

Barriers and Facilitators to Participation in Health Screening: an Umbrella Review Across Conditions

Screening is an essential prevention practice for a number of health conditions. However, screening coverage remains generally low. Studies that investigate determinants of screening participation are becoming more common, but oftentimes investigate screening for health conditions in an individualized rather than integrated fashion. In routine clinical practice, however, healthcare professionals are often confronted with situations in which several screening procedures are recommended for the same patient. The consideration of their common determinants may support a more integrated screening approach. The objectives of this umbrella review were therefore to examine: 1) the determinants (barriers and facilitators) that have been identified in relation to recommended health screening procedures; and 2) the modifiable determinants (in primary care) common across health conditions or specific to individual procedures. Results were presented through a narrative synthesis. PubMed, PsycInfo and Cochrane were searched up to January 2022. Systematic reviews reporting determinants of participation in health screening procedures with grade A or B recommendation according to the US Preventive Services Task Force were included. A total of 85 systematic reviews were included, most which contained both qualitative and quantitative studies on determinants that describe individual factors (961 occurrences), social factors (113 occurrences, healthcare professional factors (149 occurrences), health system factors (105 occurrences) and screening procedure factors (99 occurrences). The most studied screening procedures concerned cervical cancer/human papillomavirus (n = 33), breast cancer (n = 28), colorectal cancer (n = 25) and the human immunodeficiency virus (n = 12). Other conditions have been under-studied (e.g. cardiovascular problems, lung cancer, syphilis). The individual domain, including determinants such as knowledge, beliefs and emotions, was the most covered across health conditions. Healthcare professional's recommendations and the quality of patient-provider communication were identified to have a strong influence on screening participation in most conditions. The other three domains included determinants which were more specific to a condition or a population. Various determinants modifiable in primary care were found in the individual domain and in the health system, healthcare professional and screening procedure domains. Quality was assessed as low for most systematic reviews included. The identification of various modifiable determinants common across conditions highlights the potential of an integrated screening participation approach. Interventions may address common determinants in a broader person-centred framework within which tailoring to specific procedures or populations can be considered. This approach needs to be explored in intervention studies. The systematic review registration is PROSPERO CRD42019126709.

Testing and healthcare seeking behavior preceding HIV diagnosis among migrant and non-migrant individuals living in the Netherlands: Directions for early-case finding

Objectives

To assess differences in socio-demographics, HIV testing and healthcare seeking behavior between individuals diagnosed late and those diagnosed early after HIV-acquisition.

Design

Cross-sectional study among recently HIV-diagnosed migrant and non-migrant individuals living in the Netherlands.

Methods

Participants self-completed a questionnaire on socio-demographics, HIV-testing and healthcare seeking behavior preceding HIV diagnosis between 2013–2015. Using multivariable logistic regression, socio-demographic determinants of late diagnosis were explored. Variables on HIV-infection, testing and access to care preceding HIV diagnosis were compared between those diagnosed early and those diagnosed late using descriptive statistics.

Results

We included 143 individuals with early and 101 with late diagnosis, of whom respectively 59/143 (41%) and 54/101 (53%) were migrants. Late diagnosis was significantly associated with older age and being heterosexual. Before HIV diagnosis, 89% of those with early and 62% of those with late diagnosis had ever been tested for HIV-infection (p<0.001), and respectively 99% and 97% reported healthcare usage in the Netherlands in the two years preceding HIV diagnosis (p = 0.79). Individuals diagnosed late most frequently visited a general practitioner (72%) or dentist (62%), and 20% had been hospitalized preceding diagnosis. In these settings, only in respectively 20%, 2%, and 6% HIV-testing was discussed.

Conclusion

A large proportion of people diagnosed late had previously tested for HIV and had high levels of healthcare usage. For earlier-case finding of HIV it therefore seems feasible to successfully roll out interventions within the existing healthcare system. Simultaneously, efforts should be made to encourage future repeated or routine HIV testing among individuals whenever they undergo an HIV test.

Predictors of late presentation and advanced HIV disease among people living with HIV in Oman (2000-2019)

Background

The aim of this study was to determine the proportions and predictors of late presentation (LP) and advanced HIV disease (AD) in Oman. LP and AD were defined as presenting with a baseline CD4 count of < 350 and < 200 cells/mm3, respectively.

Methods

We conducted a retrospective database analysis of the National HIV Surveillance System to identify Omani people (≥ 13 years old) who were diagnosed with HIV in the period between January 2000 and December 2019 and had a documented baseline CD4 cell count. We calculated the rates and trend over time of LP and AD. A logistic regression was carried out to determine the predictors of LP and AD.

Results

A total of 1418 patients, who were diagnosed with HIV in the period from January 2000 to December 2019, were included; 71% were male and 66% were heterosexuals. The median (IQR) age at diagnosis was 33 (25–39) years. Overall, 71% (95% CI: 68–73) and 46% (95% CI: 44–49) of patients had LP and AD at presentation, respectively. The LP percentage decreased from 76% in 2000–2004 to 69% in 2015–2019; AD percentage decreased from 57 to 46% over the same period. The proportions of men with LP and AD were higher than women (74% vs. 62 and 50% vs. 36%, respectively). The percentages of persons with LP among people aged 13–24, 25–49, and ≥ 50 years were 65, 71, and 84%, respectively. The proportions of persons with AD among people aged 13–24, 25–49, and ≥ 50 years were 39, 46, and 65%, respectively. Logistic regression showed that male sex, older age, having an “unknown” HIV risk factor, and living outside Muscat were independent predictors of AD. Male sex also independently predicted LP.

Conclusions

This analysis indicates that a significant proportion of new HIV cases in Oman continue to present late. This study identified patient subgroups at greatest risk of late HIV diagnosis such as men and older people. Targeted interventions and greater efforts to scale up HIV testing services in Oman are needed.

Acceptability of Nurse-Driven HIV Screening for Key Populations in Emergency Departments: A Mixed-Methods Study

BACKGROUND

Optimizing care continuum entry interventions is key to ending the HIV epidemic. Offering HIV screening to key populations in emergency departments (EDs) is a strategy that has been demonstrated to be effective. Analyzing patient and provider perceptions of such screening can help identify implementation facilitators and barriers.

OBJECTIVES

The aim of this study was to investigate the acceptability of offering nurse-driven HIV screening to key populations based on data collected from patients, nurses, and other service providers.

METHODS

This convergent mixed-methods study was a substudy of a cluster-randomized two-period crossover trial conducted in eight EDs to evaluate the effectiveness of the screening strategy. During the DICI-VIH (Dépistage Infirmier CIblé du VIH) trial, questionnaires were distributed to patients aged 18-64 years. Based on their responses, nurses offered screening to members of key populations.Over 5 days during the intervention period in four EDs, 218 patients were secondarily questioned about the acceptability of screening. Nurses completed 271 questionnaires pre- and posttrial regarding acceptability in all eight EDs. Descriptive analyses were conducted on these quantitative data. Convenience and purposeful sampling was used to recruit 53 providers to be interviewed posttrial. Two coders conducted a directed qualitative content analysis of the interview transcripts independently.

RESULTS

The vast majority of patients (95%) were comfortable with questions asked to determine membership in key populations and agreed (89%) that screening should be offered to key populations in EDs. Nurses mostly agreed that offering screening to key populations was well accepted by patients (62.2% pretrial and 71.4% posttrial), was easy to implement, and fell within the nursing sphere of competence. Pretrial, 73% of the nurses felt that such screening could be implemented in EDs. Posttrial, the proportion was 41%. Three themes emerged from the interviews: preference for targeted screening and a written questionnaire to identify key populations, facilitators of long-term implementation, and implementation barriers. Nurses were favorable to such screening provided specific conditions were met regarding training, support, collective involvement, and flexibility of application to overcome organizational and individual barriers.

DISCUSSION

Screening for key populations was perceived as acceptable and beneficial by patients and providers. Addressing the identified facilitators and barriers would help increase screening implementation in EDs.

Factors Associated with Never Testing for HIV: Directions for Targeted Testing Interventions Among Men Who Have Sex with Men

Men who have sex with men (MSM) and who are unaware of their HIV infection contribute to onward HIV transmission and are more likely to progress to severe illness. We therefore assessed determinants of never testing for HIV among MSM living in the Netherlands. Between April and July 2019, 950 HIV-negative and 122 never-tested MSM completed a cross-sectional survey on sociodemographics, HIV testing behavior, and sexual risk taking, which was distributed through gay networking sites/apps. In never-tested MSM, median age was 37 (interquartile range = 22-51) years and 37 (30%) reported recent sexual risk behavior. Never testing was associated with younger age [adjusted odds ratio (aOR) per year increase = 0.98, 95% confidence interval (CI) = 0.97-1.00, p = 0.015], having sex with men and women (aOR = 2.85, 95% CI = 1.57-5.62, p = 0.001), and not knowing others living with HIV (aOR = 3.85, 95% CI = 2.35-6.32, p < 0.001) in multi-variable logistic regression analysis. A significant interaction effect between education level and residential area was observed (p = 0.001). Among higher-educated MSM, those living outside a large urban area had higher odds of never testing compared to those living in an urban area (aOR = 6.26, 95% CI = 2.42-16.24, p < 0.001). Lower-educated MSM had higher odds of never testing irrespective of residential area (large urban area: aOR = 12.06, 95% CI = 4.00-36.38; outside large urban area: aOR 9.29, 95% CI = 3.64-23.76; p < 0.001 for both). Among MSM recently exposed to sexual risk, never testing was associated with having sex with men and women (aOR = 2.80, 95% CI = 1.09-7.18, p = 0.032) and not knowing others with HIV (aOR = 4.91, 95% CI = 1.97-12.24, p = 0.001). To conclude, testing interventions for those never tested should be tailored to residential area and education level, and inclusive of bisexuality.

Missed opportunities for HIV testing persist despite a single educational intervention: how can we close this evidence-practice gap?

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.

Implementation of Nurse-Driven HIV Screening Targeting Key Populations in Emergency Departments: A Multilevel Analysis From the DICI-VIH Trial

BACKGROUND

In countries with concentrated HIV epidemics, optimizing screening to reach individuals with undiagnosed infection is essential. The DICI-VIH study, a cluster-randomized crossover trial conducted in eight French emergency departments (EDs), found that a strategy combining nurse-driven targeted HIV screening with routine diagnostic testing was effective.

AIM

The aim was to investigate factors associated with the implementation of HIV screening targeting key populations in EDs.

METHODS

A self-administered questionnaire was distributed at registration to patients aged 18-64 years and able to give consent during the DICI-VIH intervention. Based on their responses, those belonging to key populations were offered a rapid test by triage nurses. Two key stages of the process were evaluated: questionnaire distribution by providers and test acceptance by patients. Patient information, daily workload, and ED characteristics were collected. The associations between these variables and (a) the proportion of questionnaires distributed and (b) the proportion of tests accepted were evaluated using multilevel modeling in order to examine differences in screening implementation between EDs.

RESULTS

Questionnaire distribution proportions varied from 23% to 48% across EDs. They were higher on weekdays than weekends (odds ratio, OR: 3.77; 95% CI: 3.57-3.99) and when research staff participated (OR: 1.31; 95% CI: 1.26-1.37). They decreased over time (OR: 0.76; 95% CI: 0.71-0.82; 4th [Q3] vs. 1st quartile [Q0] of intervention days) and with increased patient flow (OR: 0.61; 95% CI: 0.56-0.67; Q3 vs. Q0 of eligible patients). Test acceptance varied from 64% to 77% across EDs, increased with research staff participation (OR 1.20; 95% CI: 1.03-1.40), and decreased over time (OR: 0.75; 95% CI: 0.60-0.92; Q3 vs. Q0). Patients who accepted were more likely to be younger (OR: 0.76; 95% CI: 0.61-0.96; 50-64-year-old vs. 30-39-year-old patients).

LINKING EVIDENCE TO ACTION

Patient flow, intervention duration, weekdays, and research staff participation were important determinants of targeted screening implementation. These findings could help guide future implementation in similar settings.

Timeliness of diagnosis of HIV in Newfoundland and Labrador, Canada: A mixed-methods study

BACKGROUND

Late diagnosis of HIV is associated with poor outcomes and increased cost. Novel HIV testing promotion strategies may reduce late diagnosis. The purpose of this study was to determine the timeliness of HIV testing in Newfoundland and Labrador (NL), missed opportunities for testing, and barriers to HIV testing.

METHODS

Demographic and clinical information from individuals diagnosed with HIV in NL from 2006-2016 was retrospectively reviewed. Patients were also invited to participate in semi-structured interviews regarding knowledge about HIV transmission, risk associated with their behaviour, testing decision making, and testing opportunities.

RESULTS

Fifty-eight new HIV diagnoses occurred during the study period: 53/58 (91.4%) were male and 33/58 (56.9%) were men who have sex with men. The mean age at diagnosis was 40.6 (SD 11.05) years. CD4 count at diagnosis ranged from 2 to 1,408 cells/mm³, with a mean of 387 cells/mm³. For 39/58 (67.2%) of individuals, the first-ever HIV test was positive. Of the 58 patients, 55 (94.8%) had had health care contact within the 5 years prior to diagnosis (mean 13.7 contacts). Heterosexual men were more likely to present with a late diagnosis (p = 0.049). Ten (17.2%) individuals agreed to an interview. Thematic analysis revealed that barriers to testing were stigma, negative health care interactions, denial, and fear of the diagnosis.

CONCLUSIONS

HIV diagnosis is made later in NL than in other Canadian provinces. Late diagnosis may be prevented if HIV testing became a routine testing procedure.

Antiretroviral Drugs for Treatment and Prevention of HIV Infection in Adults: 2018 Recommendations of the International Antiviral Society-USA Panel

Importance

Antiretroviral therapy (ART) is the cornerstone of prevention and management of HIV infection.

Objective

To evaluate new data and treatments and incorporate this information into updated recommendations for initiating therapy, monitoring individuals starting therapy, changing regimens, and preventing HIV infection for individuals at risk.

Evidence Review

New evidence collected since the International Antiviral Society-USA 2016 recommendations via monthly PubMed and EMBASE literature searches up to April 2018; data presented at peer-reviewed scientific conferences. A volunteer panel of experts in HIV research and patient care considered these data and updated previous recommendations.

Findings

ART is recommended for virtually all HIV-infected individuals, as soon as possible after HIV diagnosis. Immediate initiation (eg, rapid start), if clinically appropriate, requires adequate staffing, specialized services, and careful selection of medical therapy. An integrase strand transfer inhibitor (InSTI) plus 2 nucleoside reverse transcriptase inhibitors (NRTIs) is generally recommended for initial therapy, with unique patient circumstances (eg, concomitant diseases and conditions, potential for pregnancy, cost) guiding the treatment choice. CD4 cell count, HIV RNA level, genotype, and other laboratory tests for general health and co-infections are recommended at specified points before and during ART. If a regimen switch is indicated, treatment history, tolerability, adherence, and drug resistance history should first be assessed; 2 or 3 active drugs are recommended for a new regimen. HIV testing is recommended at least once for anyone who has ever been sexually active and more often for individuals at ongoing risk for infection. Preexposure prophylaxis with tenofovir disoproxil fumarate/emtricitabine and appropriate monitoring is recommended for individuals at risk for HIV.

Conclusions and Relevance

Advances in HIV prevention and treatment with antiretroviral drugs continue to improve clinical management and outcomes for individuals at risk for and living with HIV.
