There's a lot of push-back from clinicians arguing that patients are individuals and can't be pegged into uniform clinical protocols. This argument necessarily invokes the straw-man in the guise of the 'physicians don't have control anymore' lament. I readily counter with the refrain that common things occur commonly and that most patients do fall within the parameters of protocols. Most patients with DKA need insulin, fluids and potassium. Most patients with community acquired pneumonia improve with empirically chosen antibiotics.
But the more important part of the rebuttal is that for the exceptional patients who don't conform, the clinician still has the choice to change treatment. As of yet, there's no one arguing that when justified, a clinician still doesn't have final decision making authority. Not insurance companies. Not the government. And not the egg-head proponents of protocolized medicine.
More defensively against protocols is the argument that they make trainees stupider. It's perplexing why this should be so. Currently, it's probably the case that trainees have too many models to study - each attending teaches a different method. Consolidating these should simplify the majority of cases, allow trainees to understand the basics and, as there are always exceptions, enable them to treat these non-conforming clinical quandaries.
This just published JAMA retrospective study on how well Critical Care fellows fared on their Board exams gives some initial evidence that, in fact, protocols don't make them dumber. The study divided up the fellows based on how many protocols were in place in their institution and then compared how they performed in relevant sections of the boards. What they found was that there was no difference in clinical knowledge between programs with a high number of protocols and those with a low number of protocols.
Results Ninety of 129 programs (70%) responded to the survey. Seventy-seven programs (86%) had protocols for ventilation liberation, 66 (73%) for sedation management, and 54 (60%) for lung-protective ventilation at the time of the survey. Eighty-eight (98%) of these programs had trainees who completed the ABIM Critical Care Medicine Certification Examination, totaling 553 examinees. Of these 88 programs, 27 (31%) had 0 protocols, 19 (22%) had 1 protocol, 24 (27%) had 2 protocols, and 18 (20%) had 3 protocols for at least 3 years. Forty-two programs (48%) were classified as high intensity and 46 (52%) as low intensity, with 304 trainees (55%) and 249 trainees (45%), respectively. In bivariable analysis, no difference in mean scores was observed in high-intensity (497; 95% CI, 486-507) vs low-intensity programs (497; 95% CI, 485-509). Mean difference was 0 (95% CI, –16 to 16), with a positive value indicating a higher score in the high-intensity group. In multivariable analyses, no association of training was observed in a high-intensity program with mechanical ventilation score (adjusted mean difference, −5.36; 95% CI, –20.7 to 10.0).
Conclusion Among first-time ABIM Critical Care Medicine Certification Examination examinees, training in a high-intensity ventilator protocol environment compared with a low-intensity environment was not associated with worse performance on examination questions about mechanical ventilation management.
