Application of psychosocial models to Home-Based Testing and Counseling (HBTC) for increased uptake and household coverage in a large informal urban settlement in Kenya

A systematic review and meta-analysis of the evidence for community-based HIV testing on men's engagement in the HIV care cascade

OBJECTIVE

Men with HIV are less likely than women to know their status, be on antiretroviral therapy, and be virally suppressed. This review examined men's community-based HIV testing services (CB-HTS) outcomes.

DESIGN

Systematic review and meta-analysis.

METHODS

We searched seven databases and conference abstracts through July 2018. We estimated pooled proportions and/or risk ratios (for meta-analyses) for each outcome using random effects models.

RESULTS

188 studies met inclusion criteria. Common testing models included targeted outreach (e.g. mobile testing), home-based testing, and testing at stand-alone community sites. Across 25 studies reporting uptake, 81% (CI: 75-86%) of men offered testing accepted it. Uptake was higher among men reached through CB-HTS than facility-based HTS (RR = 1.39; CI: 1.13-1.71). Over 69% (CI: 64-71%) of those tested through CB-HTS were men, across 184 studies. Across studies reporting new HIV-positivity among men (n = 18), 96% were newly diagnosed (CI: 77-100%). Across studies reporting linkage to HIV care (n = 8), 70% (CI: 36-103%) of men were linked to care. Across 57 studies reporting sex-disaggregated data for CB-HTS conducted among key populations, men's uptake was high (80%; CI: 70-88%) and nearly all were newly diagnosed and linked to care (95%; CI: 94-100%; and 94%; CI: 88-100%, respectively).

CONCLUSION

CB-HTS is an important strategy for reaching undiagnosed men with HIV from the general population and key population groups, particularly using targeted outreach models. When compared to facility-based HIV testing services, men tested through CB-HTS are more likely to uptake testing, and nearly all men who tested positive through CB-HTS were newly diagnosed. Linkage to care may be a challenge following CB-HTS, and greater efforts and research are needed to effectively implement testing strategies that facilitate rapid ART initiation and linkage to prevention services.

Factors associated with accessing and utilisation of healthcare and provision of health services for residents of slums in low and middle-income countries: a scoping review of recent literature

OBJECTIVE

To identify factors associated with accessing and utilisation of healthcare and provision of health services in slums.

DESIGN

A scoping review incorporating a conceptual framework for configuring reported factors.

DATA SOURCES

MEDLINE, Embase, CINAHL, Web of Science and the Cochrane Library were searched from their inception to December 2021 using slum-related terms.

ELIGIBILITY CRITERIA

Empirical studies of all designs reporting relevant factors in slums in low and middle-income countries.

DATA EXTRACTION AND SYNTHESIS

Studies were categorised and data were charted according to a preliminary conceptual framework refined by emerging findings. Results were tabulated and narratively summarised.

RESULTS

Of the 15 469 records retrieved from all years, 4368 records dated between 2016 and 2021 were screened by two independent reviewers and 111 studies were included. The majority (63 studies, 57%) were conducted in Asia, predominantly in India. In total, 104 studies examined healthcare access and utilisation from slum residents' perspective while only 10 studies explored provision of health services from providers/planners' perspective (three studies included both). A multitude of factors are associated with accessing, using and providing healthcare in slums, including recent migration to slums; knowledge, perception and past experience of illness, healthcare needs and health services; financial constraint and competing priorities between health and making a living; lacking social support; unfavourable physical environment and locality; sociocultural expectations and stigma; lack of official recognition; and existing problems in the health system.

CONCLUSION

The scoping review identified a significant body of recent literature reporting factors associated with accessing, utilisation and provision of healthcare services in slums. We classified the diverse factors under seven broad categories. The findings can inform a holistic approach to improving health services in slums by tackling barriers at different levels, taking into account local context and geospatial features of individual slums.
