Trends in HIV testing in the UK primary care setting: a 15-year retrospective cohort study from 2000 to 2015

Point of care HIV testing in dental settings in high-income countries: A mixed-methods systematic review

OBJECTIVES

Expanding HIV testing beyond specialized services has been a key strategic approach to eliminating the transmission of HIV. In recent years, dental settings have been identified as offering an opportunity for delivering point of care HIV testing (POCT) interventions. Intervention components and implementation strategies have varied across studies and there is uncertainty about the prevalence of undiagnosed HIV in the dental patient population. Therefore, this systematic review aimed to synthesize the HIV testing outcomes of intervention studies, identify the core components of POCT interventions implemented in dental settings; and understand the barriers and facilitators to intervention implementation.

METHODS

A mixed-methods systematic review was undertaken. Two authors reviewed abstracts and full papers for inclusion and appraised the studies using the Mixed Methods Appraisal Tool. A convergent integrated mixed methods study design underpinned the synthesis. Outcomes were presented using descriptive statistics. Intervention components were mapped to the Template for Intervention Description and Replication (TIDieR) checklist. Barriers and facilitators were described using a narrative thematic analysis.

RESULTS

POCT was offered to 22 146 dental patients, 62.5% accepted POCT. Intervention studies that reported higher uptake of testing utilized a dedicated dental or researcher staff member to provide testing, integrated testing and provided results within the routine dental appointment and adopted a provider-initiated universal approach to offering testing. Six themes emerged that were pertinent to the barriers and facilitators to HIV testing in dental setting.

CONCLUSIONS

POCT uptake in dental settings was comparable with other non-specialized health settings. Key to the operationalization of the intervention were perceptions about its value and relevance to the dental patient population, attitudes toward the intervention, logistical barriers to its implementation, the risk of HIV testing stigma to the patient-practitioner relationship and maximising the fit of the intervention within the constraints of the dental setting.

Universal-offer HIV testing in primary care: A mixed-methods evaluation of a pilot study

BACKGROUND

Offering HIV tests to all patients undergoing blood tests in primary care has been recommended by the National Institute for Health and Care Excellence (NICE) in the UK since 2016 but has not been fully adopted. We sought to evaluate the acceptability and feasibility of such a service in primary care.

METHODS

A 3-weeks pilot of offering HIV tests to all patients undergoing blood tests was conducted in a general practice in the UK and evaluated using a mixed-methods approach. Whether patients were offered and accepted tests was recorded and any differences by patient's age and gender assessed. All patients and HCPs offering testing were approached for semi-structured interviews.

RESULTS

Two-hundred-and-51 patients (mean [range] 57.5 years [18 to 97], 58% female) attended blood test appointments with 117 being offered a HIV test (46.6%). 78.6% (n = 92) accepted testing with 91 negative results. The proportion of patients offered testing was associated with the HCP offering the test. No associations between the age or gender of the patient and their odds of being offered or accepting a test were observed. Patient semi-structured interviews (n = 13) revealed a range of previous HIV testing experiences, patients felt the "offer" of a test to be routine and non-judgemental and felt that receiving negative results via SMS was appropriate. Several participants reported not fully considering the implications of a positive result when they accepted the test. Interviews with HCPs (n = 3) identified no significant service-level barriers.

CONCLUSIONS

Offering HIV tests to patients undergoing blood tests in primary care is feasible and acceptable. The principal barrier to uptake was HCPs not offering testing.

Universal Viral Screening of Patients with Newly Diagnosed Cancer in the United States: A Cost-efficiency Evaluation

Recommendations for universal screening of patients with cancer for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) are inconsistent. A recent multisite screening study (S1204) from the SWOG Cancer Research Network found that a substantial number of patients with newly diagnosed cancer had previously unknown viral infections. The objective of this study was to determine the cost-efficiency of universal screening of patients with newly diagnosed cancer. We estimated the cost-efficiency of universal screening of new cancer cases for HBV, HCV, or HIV, expressed as cost per virus detected, from the health care payer perspective. The prevalence of each virus among this cohort was derived from S1204. Direct medical expenditures included costs associated with laboratory screening tests. Costs per case detected were estimated for each screening strategy. Secondary analysis examined the cost-efficiency of screening patients whose viral status at cancer diagnosis was unknown. Among the possible options for universal screening, screening for HBV alone ($581), HCV alone ($782), HBV and HCV ($631) and HBV, HCV, and HIV ($841) were most efficient in terms of cost per case detected. When screening was restricted to patients with unknown viral status, screening for HBV alone ($684), HBV and HCV ($872), HBV and HIV ($1,157), and all three viruses ($1,291) were most efficient in terms of cost per newly detected case. Efficient viral testing strategies represent a relatively modest addition to the overall cost of managing a patient with cancer. Screening for HBV, HCV, and HIV infections may be reasonable from both a budget and clinical standpoint.

SIGNIFICANCE

Screening patients with cancer for HBV, HCV, and HIV is inconsistent in clinical practice despite national recommendations and known risks of complications from viral infection. Our study shows that while costs of viral screening strategies vary by choice of tests, they present a modest addition to the cost of managing a patient with cancer.

Area-based comparison of risk factors and testing rates to improve sexual health care access: cross-sectional population-based study in a Dutch multicultural area

OBJECTIVES

Areas with high sexually transmitted infection (STI) testing rates may not require additional strategies to improve testing. However, it may be necessary to intervene in areas with elevated STI risk, but with low STI testing rates. We aimed to compare STI-related risk profiles and STI testing rates by geographical area to determine areas for improvement of sexual healthcare access.

DESIGN

Cross-sectional population-based study.

SETTING

Greater Rotterdam area, the Netherlands (2015-2019).

PARTICIPANTS

All residents aged 15-45 years. Individual population-based register data were matched with laboratory-based STI testing data of general practitioners (GPs) and the only sexual health centre (SHC).

OUTCOME MEASURES

Postal code (PC) area-specific STI risk scores (based on age, migratory background, education level and urbanisation), STI testing rates and STI positivity.

RESULTS

The study area consists of approximately 500 000 residents aged 15-45 years. Strong spatial variation in STI testing, STI positivity and STI risk was observed. PC area testing rate ranged from 5.2 to 114.9 tests per 1000 residents. Three PC clusters were identified based on STI risk and testing rate: (1) high-high; (2) high-low; (3) low, independently of testing rate. Clusters 1 and 2 had comparable STI-related risk and STI positivity, but the testing rate differed greatly (75.8 vs 33.2 per 1000 residents). Multivariable logistic regression analysis with generalised estimating equation was used to compare residents in cluster 1 and cluster 2. Compared with cluster 1, residents in cluster 2 more often did not have a migratory background, lived in less urbanised areas with higher median household income, and more distant from both GP and SHC.

CONCLUSION

The determinants associated with individuals living in areas with high STI-related risk scores and low testing rates provide leads for improvement of sexual healthcare access. Opportunities for further exploration include GP education, community-based testing and service (re)allocation.

Changing co-morbidity and increasing deprivation among people living with HIV: UK population-based cross-sectional study

BACKGROUND

The great success of HIV treatments means that, increasingly, people living with HIV (PLHIV) are growing old enough to develop age-associated comorbid conditions. We investigated the evolution of comorbid conditions and demographics among PLHIV in England.

METHODS

In a cross-sectional study linking Clinical Practice Research Datalink (CPRD) primary care, hospitalization, death registry and Index of Multiple Deprivation data, we measured the prevalence of 304 individual health conditions, categorized into 47 condition groups (36 non-communicable, 11 communicable). Using logistic regression, we calculated odds ratios (ORs) for the likelihood of each condition and condition group in 2015 versus 2008, adjusting for age, sex and deprivation.

RESULTS

In 2015, there were 964 CPRD-registered PLHIV compared with 1987 in 2008; 62% were male and 38% female in both cohorts. The 2015 cohort was older, with 51.1% aged 45-64 years and 7.2% aged 65-84 years compared with 31.8% and 3.2%, respectively, in 2008. Deprivation was higher in 2015, at 23.9% (quintile 4) and 28.7% (quintile 5) compared with 5.8% and 6.6%, respectively, in 2008. Of 36 non-communicable condition groups, 14 (39%) occurred in ≥ 10% of PLHIV in 2015, of which seven were more likely in 2015 than in 2008: renal-chronic-kidney-disease [odds ratio (OR) = 1.96 (95% CI: 1.33-2.90); endocrine-obesity [OR = 1.76 (1.12-2.77)]; rheumatology [OR = 1.64 (1.30-2.07)]; dermatology [OR = 1.55(1.29-1.85)]; genito-urinary-gynaecological [OR = 1.44(1.18-1.76)]; eyes-ears/nose/throat [OR = 1.31(1.08-1.59)]; and gastro-intestinal conditions [OR = 1.28 (1.04-1.58)]. Two condition groups, respiratory-chronic-obstructive-pulmonary-disease [OR = 0.36 (0.19-0.69)] and endocrine-diabetes [OR = 0.49 (0.34-0.70)], were less likely in 2015. Ten out of 11 communicable infectious condition groups were less likely in 2015.

CONCLUSIONS

Although infections in PLHIV have fallen, chronic non-communicable comorbidity is increasingly prevalent. Alongside the marked increases in deprivation and ageing, this study suggests that socio-economic measures in addition to healthcare provision are needed to achieve holistic health for PLHIV.
