Inadequete exams are not limited to EMS.
They are not even limited to any particular field of healthcare.
Around the world I have witnessed providers, some MDs, who are lax in their exams, histories, and even diagnostics, who write off patients they feel are unworthy or uninteresting in some way.
In my experience and it seems to be shared by many of my associates at all levels, nonacademic medical centers are notorious for harboring these types of providers.
I have seen some of these facilities and by extension their providers who are so bad, they should be closed down, the building bulldozed, and the ground salted. The employees forever banished from the healthcare realm in shame.
Many of these providers see nothing at all wrong with their practices.
In some instances a paramedic like Linuss in the back of a rig will be considerably better care then a fair amount of these providers.
I think it is important to remember that not every patient is hovering on the brink of death by some obscure disease. That it is both economically and practically impossible to run every test on every patient.
There is merit in epidemiology as well as clinical usefulness in using it as part of forming a dx.
Specialized providers should not get too caught up in their ability to point out obscure pathology relating to their field as a measure of superiority. For some providers are required to be generalists and provide supportive care until specialists can be engaged.
