Designing HIV Testing and Self-Testing Services for Young People in Nigeria: A Discrete Choice Experiment

Social network-based approaches to HIV testing: a systematic review and meta-analysis

INTRODUCTION

Social network-based testing approaches (SNAs) encourage individuals ("test promoters") to motivate sexual partners and/or those in their social networks to test for HIV. We conducted a systematic review to examine the effectiveness, acceptability and cost-effectiveness of SNA.

METHODS

We searched five databases from January 2010 to May 2023, and included studies that compared SNA with non-SNA. We used random-effects meta-analysis to combine effect estimates. Certainty was assessed using the GRADE approach.

RESULTS

We identified 47 studies. SNA may increase uptake of HIV testing compared to non-SNA (RR 2.04, 95% CI: 1.06-3.95, Low certainty). The proportion of first-time testers was probably higher among partners or social contacts of test promoters using SNA compared to non-SNA (RR 1.49, 95% CI: 1.22-1.81, Moderate certainty). The proportion of people who tested positive for HIV may be higher among partners or social contacts of test promoters using SNA compared to non-SNA (RR 1.84, 95% CI: 1.01-3.35, Low certainty). There were no reports of any adverse events or harms associated with SNA. Based on six cost-effectiveness studies, SNA was generally cheaper per person tested and per person diagnosed compared to non-SNA. Based on 23 qualitative studies, SNA is likely to be acceptable to a variety of populations.

DISCUSSION

Our review collated evidence for SNA to HIV testing covering the key populations and the general population who may benefit from HIV testing. We summarized evidence for the effectiveness, acceptability and cost-effectiveness of different models of SNA. While we did not identify an ideal model of SNA that could be immediately scaled up, for each setting and population targeted, we recommend various implementation considerations as our meta-analysis showed the effectiveness might differ due to factors which include the testing modality (i.e. use of HIV self-testing), type of test promoters, long or short duration of recruitment and use of financial incentives.

CONCLUSIONS

Social network-based approaches may enhance HIV testing uptake, increase the proportion of first-time testers and those testing positive for HIV. Heterogeneity among studies highlights the need for context-specific adaptations, but the overall positive impact of SNA on HIV testing outcomes could support its integration into existing HIV testing services.

Acceptability and strategies for enhancing uptake of human immunodeficiency virus self-testing in Nigeria

BACKGROUND

In 2019, the Nigerian Ministry of Health published the first operational guidelines for human immunodeficiency virus self-testing (HIVST) to improve access to human immunodeficiency virus (HIV) testing services among undertested populations in the country. Also, as part of the campaign to increase HIV testing services in Nigeria, the Nigerian Ministry of Health developed standard operating procedures for using HIVST kits.

AIM

To systematically review the acceptability and strategies for enhancing the uptake of HIVST in Nigeria.

METHODS

The systematic review was conducted and reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Different databases were searched to get the necessary materials needed for this review. Standardized forms developed by the authors were used for data extraction to minimize the risk of bias and ensure that the articles used for the study were properly screened. Identified articles were first screened using the titles and their abstracts. The full papers were screened, and the similarities of the documents were determined. Qualitative, quantitative, and mixed-method studies were evaluated using the Critical Appraisal Skills Programme and Critical Appraisal Framework criteria.

RESULTS

All the publications reviewed were published between 2015 and 2022, with 33.3% published in 2021. Most (77.8%) of the studies were cross-sectional, 43.3% were conducted in Lagos State, and 26.3% were conducted among young people. The study revealed a high level of acceptability of HIVST. Certain factors, such as gender, sexual activity, and previous testing experience, influence the acceptability of HIV self-testing, with some individuals more likely to opt-out. The cost of the kit was reported as the strongest factor for choosing HIVST services, and this ranged from 200 to 4000 Naira (approximately United States Dollar 0.55-11.07), with the majority willing to pay 500 Naira (approximately United States Dollar 1.38). Privately-owned, registered pharmacies, youth-friendly centres, supermarkets, and online stores were the most cited access locations for HIVST. The least influential attribute was the type of specimen needed for HIVST. Strategies addressing cost and preferred access points and diverse needs for social media promotion, local translation of product use instructions, and HIVST distribution led by key opinion leaders for key populations were found to significantly enhance HIVST uptake and linkage to care.

CONCLUSION

HIVST acceptability is generally high from an intention-to-use perspective. Targeted strategies are required to improve the acceptability of HIV self-testing, especially among males, sexually active individuals, and first-time testers. Identified and proposed uptake-enhancing strategies need to be investigated in controlled settings and among different populations and distribution models in Nigeria.

Preferences for accessing sexual health services among middle-aged and older adults in the UK: a study protocol for a discrete choice experiment using mixed methods

INTRODUCTION

Sexual health is essential for general health and well-being. Sexual health services for middle-aged and older adults are not prioritised and optimising available services for this population is often overlooked. Not much is known about preferences for accessing sexual health services among middle-aged and older people or level of satisfaction with current services. The aim of this study is to explore preferences for seeking sexual health services among middle-aged and older adults in the UK. This study will use discrete choice experiments (DCEs) including initial qualitative interviews followed by the survey, which have been used as a tool to explore preferences in various health service delivery.

METHODS AND ANALYSIS

The project will be carried out in two phases. First, we will conduct in-depth semi-structured interviews with 20-30 adults (aged 45+), including disabled people, and those from sexual minority groups resident in the UK. Interviews will explore indications, preferences and factors related to accessing sexual health services. Themes and subthemes emerging from the analysis of the interviews will then be used to design the choice sets and attribute level for the DCEs. For the second phase, for the DCEs, we will design choice sets composed of sexual health service delivery scenarios. The software Ngene will be used to develop the experimental design matrix for the DCE. We will use descriptive statistics to summarise the key sociodemographic characteristics of the study population. Multinomial logit, latent class and mixed logit models will be explored to assess sexual health service preferences and preference heterogeneity.

ETHICS AND DISSEMINATION

Ethical approval for both parts of this study was granted by the Research and Ethics Committee at the London School of Hygiene & Tropical Medicine. Findings from this study will be disseminated widely to relevant stakeholders via scheduled meetings, webinars, presentations and journal publications.

HIV Testing Uptake According to Opt-In, Opt-Out or Risk-Based Testing Approaches: a Systematic Review and Meta-Analysis

Purpose of Review

Improving HIV testing uptake is essential to ending the HIV pandemic. HIV testing approaches can be opt-in, opt-out or risk-based. This systematic review examines and compares the uptake of HIV testing in opt-in, opt-out and risk-based testing approaches.

Recent Findings

There remain missed opportunities for HIV testing in a variety of settings using different approaches: opt-in (a person actively accepts to be tested for HIV), opt-out (a person is informed that HIV testing is routine/standard of care, and they actively decline if they do not wish to be tested for HIV) or risk-based (using risk-based screening tools to focus testing on certain individuals or sub-populations at greater risk of HIV). It is not clear how the approach could impact HIV test uptake when adjusted for other factors (e.g. rapid testing, country-income level, test setting and population tested).

Summary

We searched four databases for studies reporting on HIV test uptake. In total, 18,238 records were screened, and 150 studies were included in the review. Most studies described an opt-in approach (87 estimates), followed by opt-out (76) and risk-based (19). Opt-out testing was associated with 64.3% test uptake (I² = 99.9%), opt-in testing with 59.8% (I² = 99.9%) and risk-based testing with 54.4% (I² = 99.9%). When adjusted for settings that offered rapid testing, country income level, setting and population tested, opt-out testing had a significantly higher uptake (+ 12% (95% confidence intervals: 3–21), p = 0.007) than opt-in testing. We also found that emergency department patients and hospital outpatients had significantly lower HIV test uptake than other populations.

Self-care interventions for sexual and reproductive health in humanitarian and fragile settings: a scoping review

BACKGROUND

Self-care is the ability of individuals, families, and communities to promote health, prevent disease, maintain health, and manage illness and disability with or without a health care provider. In resource-constrained settings with disrupted sexual and reproductive health (SRH) service coverage and access, SRH self-care could play a critical role. Despite SRH conditions being among the leading causes of mortality and morbidity among women of reproductive age in humanitarian and fragile settings, there are currently no reviews of self-care interventions in these contexts to guide policy and practice.

METHODS

We undertook a scoping review to identify the design, implementation, and outcomes of self-care interventions for SRH in humanitarian and fragile settings. We defined settings of interest as locations with appeals for international humanitarian assistance or identified as fragile and conflict-affected situations by the World Bank. SRH self-care interventions were described according to those aligned with the Minimum Initial Services Package for Reproductive Health in Crises. We searched six databases for records using keywords guided by the PRISMA statement. The findings of each included paper were analysed using an a priori framework to identify information concerning effectiveness, acceptability and feasibility of the self-care intervention, places where self-care interventions were accessed and factors relating to the environment that enabled the delivery and uptake of the interventions.

RESULTS

We identified 25 publications on SRH self-care implemented in humanitarian and fragile settings including ten publications on maternal and newborn health, nine on HIV/STI interventions, two on contraception, two on safe abortion care, one on gender-based violence, and one on health service provider perspectives on multiple interventions. Overall, the findings show that well-supported self-care interventions have the potential to increase access to quality SRH for crisis-affected communities. However, descriptions of interventions, study settings, and factors impacting implementation offer limited insight into how practical considerations for SRH self-care interventions differ in stable, fragile, and crisis-affected settings.

CONCLUSION

It is time to invest in self-care implementation research in humanitarian settings to inform policies and practices that are adapted to the needs of crisis-affected communities and tailored to the specific health system challenges encountered in such contexts.
