20-year Quebec study reveals socio-economic inequalities impact access to AIDS treatment despite universal health care
McGill University Health Centre
Quebecers do not have equal access to anti-retroviral treatment (ART) for HIV and AIDS, a long-term study undertaken by a team from the Research Institute of the McGill University Health Centre (RI-MUHC) in collaboration with clinics and university health centres in Montreal, has revealed. Researchers observed that HIV-infected persons who count on social assistance and other income security programs in Quebec do not have early access to ART due to their presumed lower socio-economic status.
According to the paper published in the Journal of the International AIDS Society, social welfare recipients and others who do not have paid employment struggle for early access to necessary ART despite access to universal health care. Early ART is a key factor in reducing AIDS and non-AIDS events, including cardiovascular, renal, hepatic and neurocognitive disorders, and cancer among persons living with HIV. In addition, early treatment also significantly decreases the risk of HIV transmission.
“This paper shows we need to take socio-economic factors into consideration when it comes to better controlling the HIV epidemic in Canada. People who are vulnerable economically may be put at greater risk because access to ART is delayed,” says study lead author Dr. Jean-Pierre Routy, a senior scientist from the Infectious Diseases and Immunity in Global Health (IDIGH) Program at the RI-MUHC and a hematologist at the Chronic Viral Illness Service of the MUHC.
From 1996 to 2015, Dr. Routy’s Montreal-based research team looked at a cohort of 549 participants, early in their HIV infection determining those who count on income security such as social assistance and employment insurance benefits were not accessing ART early. Indeed, working persons earning a salary were two-and-a-half times more likely to initiate early ART compared to this group.
This delayed access represents a potential setback in fighting HIV in Quebec. Despite the availability of universal health care and medication insurance, care appears to be inequitable.
“People who are unemployed and depend on income support are faced with tough daily decisions on how they use limited resources. Competing needs may lead to less capacity to engage in care and related expenses. This population needs aid,” explains Dr. Routy, who is also a professor in the Department of Medicine, Division of Hematology at the Faculty of Medicine of McGill University.
“This study is very important because it demonstrates that people delay or end their treatment due to financial reasons, putting their own health at risk,” says study co-author, Dr. Réjean Thomas, founder and president of L’Actuel Medical Clinic in Montreal. “We’re talking about a very worrying public health matter since we’ve known for years that an HIV-infected person with an undetectable viral load undergoing antiretroviral treatment cannot transmit the disease.”
“In a specialized clinic like l’Actuel, over 90 per cent of diagnosed patients begin treatment very early after their diagnosis compared to 30 per cent just 10 years ago,” adds Dr. Thomas.
“The effect of type of care centres on early treatment initiation was an interesting finding that we did not expect,” adds first study author Dr. Vikram Mehraj, postdoctoral fellow in the IDIGH Program at the RI-MUHC. “We believe this finding can be explained in part by the fact that sicker patients may preferentially use university-medical centres.”
Unlike in British Columbia or France, ART for persons living with HIV in Quebec is still not entirely free. Dr. Thomas points to the obstacle of annual charges for treatment ranging from $28,000 to $36,000.
“If we want to eradicate HIV by 2030 – in line with the UNAIDS objectives signed by the city of Montreal on December 1, 2017 – we will have to seriously examine this obstacle moving forward,” says Dr. Thomas.
