Medical diagnosis is a simple matter of taking a history, performing an examination, and reviewing the results of ancillary testing; except when it’s a complicated case of eliciting subtle nuances from the patient in both the interview and the exam, and interpreting multiple pieces of conflicting data.
Medical treatment is a straightforward affair of providing appropriate treatment; except when there are multiple treatment options with unclear risks and benefits, technically challenging surgical or other procedures to perform, not to mention fully informing the patient and family about all of those treatment options, risks, and benefits, plus eliciting and answering all their questions.
Nothing to it.
Notice, though, that the key ingredient here is DIAGNOSIS. Performing a flawless appendectomy won’t do a thing for an ovarian cyst, nor will a PPI prescription do much for an acute coronary syndrome. Performance measures that look at treatment without addressing diagnosis are somewhere between misguided and ludicrous.
Why does American medicine have this so bass-ackwards? Follow the money. Thanks to the specialty-heavy RUC, the commission that sets fees for various procedures, doing something — anything — is paid far more handsomely than thinking (even thinking about what to do).
