I was interested in the question of why murmurs are expressed in arabic numerals as well as why the BOS uses lower case when referring to roman and arabic numerals. I sent them a note and here's what Diane Heath, Research Assistant said.
quote:
Deb, we here at AAMT aren't in the business of making arbitrary decisions when it comes to style. Any recommendations we make are based on researching reputable sources. In the case of cardiac murmurs, I refer you to p. 349 of the American Medical Association Manual of Style, which states that "murmurs are written in arabic numerals." This manual also lowercases roman and arabic when referring to numerals.The Gregg Reference Manual, in sections 468 and 469 (p. 120) uses lowercase for arabic and roman, as does the Chicago Manual of Style in its index and in the body of the book.
Styles do change. Consider the American Diabetes Association, which for most of its life used roman numerals for diabetes classification. Several years ago they changed to arabic numerals.
Anyway, there is no way we would just throw something into the Book of Style without having a good basis for our choice. Physicians don't always agree with our choices; many prefer to do it "the way we have always done it." If they insist, doing it their way may be necessary. Lots of
MTs say that something is "the way we have always done it," but times do change, as do styles. We hope that medical transcriptionists will thoughtfully consider the style suggestions in the BOS and know that we did our homework before we suggested changes that would bring our profession the most up-to-date conclusions.
We appreciate the excellent material found on MTDesk and the efforts the MTDesk staff makes to support the medical transcription profession. It is to MTDesk that I always send individuals who are interested in or new to the profession, for I know that the discussion forums there will always be well moderated and supportive and that they are more likely to find useful information there than on almost any other MT forum with which I am familiar.
Thanks very much for giving us the opportunity to respond to your questions.
I thank Diane and the AAMT for their time today and the monumentous effort put forth in producing the BOS. I personally am grateful for the principles and structure they provide; if we were without it, it would just be the Wild, Wild West out there.
Thanks again all for provoking my thoughts today.
