Background:
Late diagnosis of HIV is associated with poor outcomes and increased cost. Novel HIV testing promotion strategies may reduce late diagnosis. The purpose of this study was to determine the timeliness of HIV testing in Newfoundland and Labrador (NL), missed opportunities for testing, and barriers to HIV testing.
Methods:
Demographic and clinical information from individuals diagnosed with HIV in NL from 2006-2016 was retrospectively reviewed. Patients were also invited to participate in semi-structured interviews regarding knowledge about HIV transmission, risk associated with their behaviour, testing decision making, and testing opportunities.
Results:
Fifty-eight new HIV diagnoses occurred during the study period: 53/58 (91.4%) were male and 33/58 (56.9%) were men who have sex with men. The mean age at diagnosis was 40.6 (SD 11.05) years. CD4 count at diagnosis ranged from 2 to 1,408 cells/mm3, with a mean of 387 cells/mm3. For 39/58 (67.2%) of individuals, the first-ever HIV test was positive. Of the 58 patients, 55 (94.8%) had had health care contact within the 5 years prior to diagnosis (mean 13.7 contacts). Heterosexual men were more likely to present with a late diagnosis (p = 0.049). Ten (17.2%) individuals agreed to an interview. Thematic analysis revealed that barriers to testing were stigma, negative health care interactions, denial, and fear of the diagnosis.
Conclusions:
HIV diagnosis is made later in NL than in other Canadian provinces. Late diagnosis may be prevented if HIV testing became a routine testing procedure.
