Re: Circumstantial evidence-based medicine

Issue: BCMJ, vol. 54 , No. 7 , September 2012 , Pages 325-326 Letters

I read with interest the article “Prescri­bing second-generation antipsychotic medications: Practice guidelines for general practitioners” [BCMJ 2012;54:75-82]. As a laboratory phy­­sician, my interest was piqued when I noticed that the recommended laboratory eval­uations included fasting insulin under certain circumstances. 

As it was un­clear to me how this investigation could contribute anything other than cost to the assessment, I decided to investigate the basis for this recommendation. As it was based on the Canadian Alliance for Monitoring Effectiveness and Safety of Antipsychotics in Children (CAMESA) guidelines, I review­ed the relevant guideline. 

During the course of this review I learned “if there is good evidence that a specific side effect occurs with SGA treatment, monitoring for the specific side effect may improve health outcomes in the long term.” This is what I (though I am not a lawyer) would consider circumstantial evidence. As a laboratory physician and the chair of the BCALP Tariff Committee, I can assure you that the Medical Services Plan would not consider this an adequate justifica­tion if we were to submit it in support of a new or otherwise modified fee.

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.
