CAST concerns

The provision of stable safe housing, social supports, coun­seling, and a regular family physician to substance-addicted people on Vancouver’s Downtown Eastside is clearly one of the most exciting and potentially efficacious initiatives to be proposed in recent Vancouver medical care and research. 

What is less clear is the rationale for tying these interventions to pharmacological substitution—the core of the CAST (Chronic Addiction Substitution Treatment Trials) initiative.

Even more troubling to us as physicians is the statement on the CAST web site that “substitution therapy is a means of reducing the users’ impact on public order and public health until durable solutions are reached.” This is not health care, nor is it likely that it represents the goal of addicted patients.

Does this mean that the chances for recovery for addicts is so small that the only option is to be “safely and ethically” managed through the CAST initiative with its stated primary goal being “… to significantly reduce crime and disorder in Vancouver by 2010”?

We believe that the widespread introduction of safe housing, a regular family doctor, and social supports are the cornerstones in the management of patients with addictions. The positive effects of these interventions are well researched and well docu­mented. 

It is equally well supported that homeless, socially unstable, and/or doctorless people are more likely to suffer from addictions (see Vision maga­zine and its citations, summer 2007, The Roots of Addiction in a Free Market Society, 2005 and virtually any text on addictions medicine).

We believe that the CAST initiative is a poorly conceived strategy that has negative consequences. We are concerned that the provision of housing, counseling, or access to a family doctor may be tied to participation in the CAST initiative, and those same services denied to addicts who decline. 

What will happen to study dropouts? Will they lose their doctor/home/social supports? If we begin to base our decisions on social quietude vs. sound medical principle, can we in all good conscience claim to follow the tenets of the Hippocratic Oath and keep our patients free “from harm and injustice”?

Above is the information needed to cite this article in your paper or presentation. The International Committee of Medical Journal Editors (ICMJE) recommends the following citation style, which is the now nearly universally accepted citation style for scientific papers:
Halpern SD, Ubel PA, Caplan AL, Marion DW, Palmer AM, Schiding JK, et al. Solid-organ transplantation in HIV-infected patients. N Engl J Med. 2002;347:284-7.

About the ICMJE and citation styles

The ICMJE is small group of editors of general medical journals who first met informally in Vancouver, British Columbia, in 1978 to establish guidelines for the format of manuscripts submitted to their journals. The group became known as the Vancouver Group. Its requirements for manuscripts, including formats for bibliographic references developed by the U.S. National Library of Medicine (NLM), were first published in 1979. The Vancouver Group expanded and evolved into the International Committee of Medical Journal Editors (ICMJE), which meets annually. The ICMJE created the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals to help authors and editors create and distribute accurate, clear, easily accessible reports of biomedical studies.

An alternate version of ICMJE style is to additionally list the month an issue number, but since most journals use continuous pagination, the shorter form provides sufficient information to locate the reference. The NLM now lists all authors.

BCMJ standard citation style is a slight modification of the ICMJE/NLM style, as follows:

  • Only the first three authors are listed, followed by "et al."
  • There is no period after the journal name.
  • Page numbers are not abbreviated.
