Assessing uptake of national HIV screening and testing guidance—Part 2: Knowledge, comfort and practice

Abstract

Background: The Public Health Agency of Canada's (PHAC) HIV Screening and Testing Guide (the Guide) provides guidance to health care providers regarding who, when and how often to screen for HIV. HIV screening and testing is important in meeting the Joint United Nations Programme on HIV/AIDS' (UNAIDS) 90-90-90 targets towards HIV elimination. Objective: To determine health care providers' levels of knowledge about and comfort with aspects of HIV testing, and to determine whether their HIV testing practices are consistent with the recommendations in the Guide. Methods: An open, anonymous online survey that included questions on knowledge, comfort and HIV testing practices was developed with stakeholders, validated and pre-tested. It was then disseminated to a convenience sample of health care providers across Canada between June and August 2016. Results: A total of 1,075 participants representing all Canadian provinces and territories responded to the survey, with the majority being nurses (54%) and physicians (12%). Overall, knowledge related to HIV testing was substantial, but 37% of respondents underestimated the percentage of people living with HIV in Canada who are unaware of their HIV status and only 32% of respondents knew that HIV patients are frequently symptomatic during the acute infection. Most participants were comfortable with HIV testing and approximately 50% reported offering HIV testing regularly. Conclusions: Although overall knowledge and practice were consistent with PHAC's HIV Screening and Testing Guide, some health care providers may underestimate the magnitude of undiagnosed HIV cases in Canada and may misinterpret the symptoms of acute HIV infection. While the amplitude of these results need to be interpreted in light of the convenience sample, addressing these knowledge gaps may facilitate earlier diagnosis of HIV among those who are unaware of their HIV status.

Assessing uptake of national HIV screening and testing guidance—Part 1: Awareness, use and usefulness

“…The objective of Part 1 was to evaluate the awareness, use and perceived usefulness of the Guide. The objective of Part 2 was to assess health care providers' knowledge, comfort and clinical practices related to HIV testing (6). The overall study is part of the work underway to inform potential updates of the Guide to support HIV screening and testing practices in Canada.…”
