Ideas on improving rates of missed/delayed diagnoses in PCP type visits.

Yes. We are trying to run the machine faster than it is engineered to run and we have few tools in place to measure where it is going awry. How often do I make diagnostic errors? I don't know and really have no way of knowing. I try not to make them but I, like all docs make mistakes. How many is too many? Don't know that since we don't measure them and have no benchmarks.

What measurements we get are received well after we have forgotten the details of the encounters and have the ability to make adjustments and we receive them as individual anecdotes, not actual numerators and denominators. We can't really tell how we are doing other than the random complaint or complement or scary malpractice suit.

This realization does not constitute whining. It is a realization that the tools and approaches we were trained to use are no longer sufficient to manage the information required. What we are asked to do is not possible. The expectations from our patients of what we can accomplish is beyond what we are capable of doing as humans given the tools and approaches we have historically used.

I think that Larry and Lincoln Weed's article in the inaugural issue of Diagnosis really hits the nail on the head.

You are absolutely right on all of this. We are physicians, not machines. We need time to think about things.

This discussion by David Gordon and others  is both valuable and frustrating.
When I began to practice medicine we did exactly what David Gordon suggested:  we used the concept of a "rule/out" diagnosis.  We also had the luxury of putting in the differential diagnosis. Working in the emergency department we often did not have the complete information that would allow us to be "certain" as to what was wrong with a patient.  And even better, if we knew a patient warranted a hospitalization but the diagnosis was not yet certain I could call an attending physician (who often knew the patient from previous care), tell him/her what I had found, admit that I did not know the diagnosis and the patient was admitted.  That was true if the patient did not have a doctor and was assigned to the on call doctor.   Or I could keep the patient and observe until the private physician/on call doctor came to see the patient.

All of that is gone.  Third party insurance companies and the government want certainty.  You can't put down a rule out or you won't get pain.  HMOs and other insurers destroyed the patient doctor relationship forcing patients to choose doctors depending on their insurance companies and insurance companies will often change providers on patients.  That means doctors don't have a long standing relationship with patients and really get to know them

And finally, there is the "rush to judgement and treatment".  In our system an emergency department patient who is not admitted is supposed to be seen and discharged within 150 min. For the simple sprained ankle or cold that works great.  But what about the patient who "doesn't feel good" or feels "weak"?

Admitted patients are supposed to be out of the ED and admitted in 2 hrs (that means a really rapid work up, treatment, and all information back with notification of inpatient personnel).   Once again, great for obvious diagnoses  but what about a complex patient?

Then to make things even more frustrating we have "time dependent medicine".  Pneumonia: diagnose and get antibiotics on board within 4 hours which sounds simple until you realize that not all patients come in with a cough and fever; some come in confused or septic.  Or what about the patient who has abdominal pain and vomiting and turns out to have a heart attack?  Well you are supposed, ideally, to have gotten an EKG within 10 min and gotten the person treated rapidly.  Well, should I order a tropinin on all middle aged patients with abdominal pain and also do an EKG but still choose wisely to save money?.

All of this makes us prone to errors.  Medicine is very complex.  Turning medical care into big business where you need to choose wisely to save money, practice quickly, and ensure safety is a lot to require.  Oh, and I forgot about finding time to really do a good history and physical exam, explain the possible diagnoses and what needs to be done and answer questions for a patient and family.  This  does and should take time.  What doctors no longer have is time and a long history of knowing their patients.

Please understand, my remarks are not meant to sound like excuses or whining.  Someone asked, don't doctors think about and dictate a differential diagnosis?  Yes we think about it but I don't know that we dictate it any longer.  Time shortages, time rules, insurance companies and the government have all changed how we think.  We are to blame also, as we have simply turned to technology to get answers rather than demanding that we have the time to really talk to and examine patients.  That we have the courage to tell a patient that we don't know what is wrong right now and we need to do tests (not all patients are comfortable with that uncertainty and when I have done exactly that a family member looked at his father and said in front of me, "What do you mean she doesn't know?"

 What I am trying to articulate is the complexity of the practice of medicine, the uncertainty inherent in diagnosing patients and the attempt by administrators and insurance companies to apply rules to ensure efficiency and cost savings.  And perhaps our most important sin:  not having the courage to admit when we don't know.

Dr. Gordon,

Thank you so much for this.

I know this might be going out on a limb for the MD's here, but do you
all believe that patients' expectation of a diagnosis, leads one to give
them something, even if it is incorrect? Like giving antibiotics for the
flu? Maybe that is an avenue we need to think about: how do we manage
patient expectations so that they're not "preconditioned", or other
practioners only looking at ICD-9/CPT codes and going 'set in stone' vs.
'maybe'?

Physicians are thus socialized into a lack of scientific integrity, a condition that permeates medical practice."

I would say most ED diagnosis in particular would be better explicitly framed as "diagnostic hypothesis" that should still be viewed critically and challenged (in a constructive and congenial manner).

I really wish I could admit someone with the "Not yet diagnosed" qualifier that Pat revealed is available in Canada. Here, I am hand-cuffed by attaching a diagnostic label to a patient encounter even when I am not sure of it. I try to explain the tentativeness of the diagnosis in my charting but that doesn't always get perpetuated in the record. I used to try to get around this by having the patient's diagnosis be their symptom (e.g., shortness of breath, chest pain, etc...) but this is frowned upon.  I think our reimbursement system poses conflict with patient safety goals.

When practice guidelines come out, the specific recommendations are qualified with some scale that reflects the strength of recommendation and quality of evidence. Maybe our classification system for diagnosis would benefit from similar modifiers that reflect the level of certainty involved... say for example: pulmonary embolism (confirmed vs suspected vs needs further testing).  Just some thoughts off the top of my mind...
