Furthermore, among individuals who have started on HAART, discontinuation rates have been shown to vary greatly from 6% [9] to 51% at 1 year of follow-up [10–13]. Given the compelling public health need to ensure that as many people benefit from HAART as possible, trying to re-engage individuals who have initiated HAART but have later interrupted therapy should be seen as a priority. However, few studies have examined the characteristics and outcomes of patients www.selleckchem.com/products/Belinostat.html who have interrupted HAART. When examining these issues, it is

important to distinguish non-medically supervised treatment interruptions (TIs) from structured TIs, which were considered to be a viable clinical option earlier in this decade [14], but are now no longer recommended [15]. We conducted an analysis Staurosporine nmr to examine the characteristics of individuals who interrupted their treatment within a free-of-charge ART programme in British Columbia (BC), Canada and to determine what factors were associated with restarting HAART. Finally, we examined trends in the frequency of TIs within the programme over time. The BC HIV/AIDS Drug Treatment Programme (DTP) of the BC Centre for Excellence in HIV/AIDS (‘the Centre’) distributes antiretroviral drugs at no cost to HIV-infected individuals who reside in BC. HAART is prescribed based on the Therapeutic Guidelines of

the Centre [16], which since 1996 have remained consistent with those of the International AIDS Society, USA [15]. Physicians enrolling an HIV-infected individual must complete a drug request form, which compiles information on the applicant’s address, past HIV-specific drug history, CD4 cell counts, plasma HIV-1 RNA, drugs requested and enrolling physician data. At the time of the first drug refill, participants are asked to provide informed consent for accessing additional medical information, including electronic records. The consent form is optional and participant’s refusal to do either does not limit access to free HAART.

HAART medications are entered into the database at the time the patient receives their first prescription and are refilled for a maximum of 3 months. All viral load (VL) testing and most CD4 testing in the Teicoplanin province of BC are conducted in laboratories at St. Paul’s Hospital and are uploaded daily into the DTP database. Additional information regarding hepatitis C status, history of injection drug use (IDU) and CD4 cell counts for individuals who do not have their CD4 cell count testing performed at St. Paul’s Hospital are obtained from the prescription refill forms. Physicians of patients who have discontinued therapy are mailed a form to collect further information on the reasons for discontinuation; and physicians may also report adverse events spontaneously to the programme. Deaths are recorded through annual linkages with BC vital statistics and physician reports.
