Sure you can post 'em. Don't be discouraged though, remember the
context of the study limitations. 46% is the indisputable
appropriate according to the lofty criteria. 20% or something was uncertain due to records, unknowns in the criteria, etc. Further, the 29% inappropriate means inappropriate according to criteria developed many years ago by a largely "skeptical" panel with a large number of non-manipulators. (It's results differed from the all chiropractic panel in appropriateness for radiculopathy, chronicity, etc and occurred before some of the later RCT studies). And the classifications are that, classifications, not medicolegal adjudications fergunnesakes.
Consider that the C-Spine panel some 5 years later (which has
even less evidence than L-spine) had similar appropriateness
indications to the LBP recommendations! This despite greater
side-effect risks implying the experts' level of comfort on
appropriateness of manipulation decisions in general must have
increased just 5 years later! One criticism I had of the RAND LBP indications was that they didn't include a role for patient
preference, but it did acknowledge a role for previous experience with manipulation decision making, something we incorporated to greater extent in the C-Spine study (I worte the C-spine indications with Hansen and Meeker). Much of the discomfort the original LBP panel had on chronicity reflects an absence of evidence (not evidence against), as well as the lack of understanding/consensus on episodic, recurrent, or chronic
definitions. What may show up in a DC's chart as a chronic LBP
case may be a recurrent "acute" episode, I don't recall the
Shekelle paper or the original LBP criteria accounting for this
very well. Now that Meade and others have come out, that might
soften from inappropriate to uncertain if the expert panel
reconvened. (I'll bet I disagree with Paul on that). How the
indications are worded also impact the appropriateness ratings
the panels give. And the inappropriate cases were a hodgepodge of these evidence-limited inappropriates, and as the paper said, do not construe harmful (like whacking away on bilateral motor
weakness, bowel control loss folks) practice.
The playing field is completely level on this one, these
limitations are the same kinds of limitations that similar
studies have done on medical procedures, hence the comparison.
Everyone (the anti-chiro folks) expected that applying such
rigorous criteria to chiros would annihilate us. It didn't. Every time we are placed toe to toe with competition, we hold our own at least. We need to mature into the big leagues and not expect every piece of research to look like a glowing press release form a trade association.
With this kind of scrutiny increasing on everyone, more fun
ahead. Stay tuned in the evidence-based practice game. The
nature, quality, and relevance of evidence and how it applies to
case-by-case practice will be interesting. Check out that BMJ
editorial (July 18, BMJ 316: ; 1621-22) on their move to
publish evidence based case reports.
OK, back to the grind, Bob
