The following is a guest post by Shawn Zhou, a country program analyst with the Clinton Foundation on the Clinton Health Access Initiative in Shanghai, China.

An interesting progressive model for combating HIV/AIDS has emerged over the past 5-10 years in Vancouver, BC. Once home to the highest rate of HIV infection growth in North America, Vancouver has seen a significant decline in the spread of HIV among its intravenous drug users. The model they’ve implemented encourages drug users to enter a “safe house”  called Insite, where individuals are free to use illicit drugs while being supervised by nurses, and are offered treatment if suspected of suffering from HIV. Insite is trying to provide an aggressive and controversial model of reaching and treating a difficult and high-risk population….and so far it appears to be working.

According to one of the center’s studies, financed by the United States National Institutes of Health, from 1996 to 2009 the number of British Columbians taking the medications increased more than sixfold — to 5,413, an estimated 80 percent of those with H.I.V. The number of annual new infections dropped by 52 percent. This happened even as testing increased and syphilis rates kept rising, indicating that people were not switching in droves to condoms or abstinence. (Full Article)

There are two key foundational beliefs to the creation of this model 1) As one nurse put it: “people are going to use drugs whether they have clean needles or they don’t.”   2) A Test and Treat system where all patients regardless of CD4 count are treated if they are HIV+ (aka….don’t prioritize patients, treat everyone, stop the spread).

This first fundamental belief is probably the biggest sticking point for those opposed to the program. Fundamentally while this model may appear to encourage drug use, as the article suggests, many other cities worldwide have already adopted free needle exchange programs as a means of encouraging cleaner and safer drug use.

A 1997 study in The Lancet found that in 29 cities worldwide with needle exchange, H.I.V. infection dropped 6 percent a year among drug injectors, while in 51 cities without, it rose by about 6 percent.

By funding a safe house for users, monitored under the careful watch of medical professionals, Vancouver has taken this belief one step further and is trying to manage dangerous behavior in a contained and safe environment.

In 2009, the site recorded 276,178 visits (an average of 702 visits per day) by 5,447 unique users; 484 overdoses occurred with no fatalities, due to intervention by medical staff. Health Canada has provided $500,000 per year to operate the site, and the BC Ministry of Health contributed $1,200,000 to renovate the site and cover operating costs. (Wikipedia site)

This is of course a difficult pill for public officials to swallow, since such clinics and programs are costly and goes against conservative principals. However, regardless of its implications on drug use, the model undeniably offers a safer environment for drug addicts than they previous had, and should probably get strong consideration in other communities in the developed world where drug use and the spread of HIV is rampant. I’m curious to see how this all shakes out as apparently Canada’s supreme court is reviewing law suits to close down the facility.
