Test@work: evaluation of workplace HIV testing for construction workers using the RE-AIM framework

Community-based HIV testing through a general health check event in a high HIV-prevalent multicultural area in Rotterdam, The Netherlands: a pilot study on feasibility and acceptance

BACKGROUND

HIV testing is crucial for finding the remaining cases in a declining HIV epidemic in The Netherlands; providing HIV testing in non-traditional settings may be warranted. We conducted a pilot study to determine the feasibility and acceptability of a community-based HIV testing (CBHT) approach with general health checks to improve HIV test uptake.

METHODS

CBHT's main conditions were low-threshold, free-of-charge, general health check, and HIV education. We interviewed 6 community leaders, 25 residents, and 12 professionals/volunteers from local organizations to outline these main conditions. Walk-in test events were piloted at community organizations, providing HIV testing along with body mass index (BMI), blood pressure, blood glucose screening, and HIV education (October 2019 to February 2020). Demographics, HIV testing history, risk perception, and sexual contact were collected via questionnaires. To evaluate the pilots' feasibility and acceptance, we utilized the RE-AIM framework and predefined goals, incorporating quantitative data from the test events and qualitative input from participants, organizations, and staff.

RESULTS

A total of 140 individuals participated (74% women, 85% non-Western, median age 49 years old). The number of participants during the seven 4-h test events ranged from 10 to 31. We tested 134 participants for HIV, and one was found positive (positivity 0.75%). Almost 90% of the participants were never tested or > 1 year ago, and 90% perceived no HIV risk. One-third of the participants had one or more abnormal test results on BMI, blood pressure, or blood glucose. The pilot was well-rated and accepted by all parties. The staff had concerns about waiting time, language problems, and privacy. Participants hardly indicated these concerns.

CONCLUSIONS

This CBHT approach is feasible, acceptable, and well-suited for testing not (recently) tested individuals and detecting new cases. Besides reducing HIV-associated stigma and increasing HIV test acceptance, offering multiple health tests may be appropriate as we frequently observed multiple health problems. Whether this laborious approach is sustainable in the micro-elimination of HIV and should be deployed on a large scale is questionable. CBHT like ours may be suitable as a supplement to more sustainable and cost-effective methods, e.g., proactive HIV testing by general practitioners and partner notification.

Opt-in HIV testing in construction workplaces: an exploration of its suitability, using the socioecological framework

Background

Late diagnosis of HIV remains a challenge, despite improved testing and treatment. Testing is often targeted at high-risk groups; workplace events might normalise testing and allow access to a wider population. The construction workforce has a number of risk factors for HIV. In the Test@Work study, HIV tests were delivered within general health checks to construction employees, with high uptake and acceptability. This paper reports on the experiences of construction managers and health professionals involved in Test@Work and explores the suitability of construction worksites as a venue for opt-in HIV testing.

Methods

Qualitative interviews (n = 24) were conducted with construction managers who had facilitated health check/HIV testing (n = 13), and delivery partners (n = 11) including i) healthcare volunteers who had delivered general health checks (n = 7) and, ii) HIV professionals who had conducted HIV testing (n = 4) at 21 Test@Work events held on construction sites. Interviews explored their experiences of these events and views towards HIV testing in the workplace. Exit questionnaires (n = 107) were completed by delivery partners after every event, providing qualitative data identifying facilitators and barriers to effective delivery. Thematic analysis identified themes that were mapped against a socioecological framework.

Results

Delivery partners reported high engagement of construction workers with workplace HIV testing, peer-to-peer encouragement for uptake, and value for accessibility of onsite testing. HIV professionals valued the opportunity to reach an untested population, many of whom had a poor understanding of their exposure to HIV risk. Managers valued the opportunity to offer workplace health checks to employees but some identified challenges with event planning, or provision of private facilities.

Conclusions

The construction sector is complex with a largely male workforce. Providing worksite HIV testing and education to an untested population who have poor knowledge about HIV risk helped to normalise testing, encourage uptake and reduce HIV-related stigma. However, there are practical barriers to testing in the construction environment. Rapid testing may not be the most suitable approach given the challenges of maintaining confidentiality on construction worksites and alternatives should be explored.
