Why We need to Improve our Differential Diagnosis Processes

Posted by Jason Maude on Wed, Sep 16, 2015 @ 12:23 PM

Within the medical industry, a staggering 30-40% of all malpractice claims come down to a misdiagnosis. Why do people get it wrong? Because they’re just that: people. Clinicians and medical professionals have years and years of training - and most likely experience too - behind them, so there’s no doubting they’re the ones to be around when you’re unwell. But humans make mistakes, and the human brain is vulnerable to error. According to Mark Graber in 2005, cognitive error contributed to 74% of all diagnostic errors studied. There is a virtually endless list of the cognitive biases that affect humans, and medical professionals are unfortunately no exception to these biases. Arguable the main sticking points for those trying to diagnose a patient, or indeed find a solution to any question, are:

Implementing any new system or protocol into a large and busy environment such as a hospital can be daunting, and it can often seem like there are more hurdles to overcome than the venture is worth. But it doesn’t have to be this way. With a few tips and some careful preparation, a smooth adoption of a differential diagnosis tool such as Isabel in your institution is perfectly achievable.

Documenting your Differential Diagnosis Could Save You in a Malpractice Case

Posted by Jason Maude on Wed, Jun 19, 2013 @ 11:28 AM

We are often asked by clinicians whether they would be better or worse off in a malpractice case if there was a record in the medical notes of their full differential diagnosis and the diagnosis missed was in that list. Our view is that it’s always better to have documented what you have done and thought. If you were wrong and had a reasonable explanation for why you did not think the diagnosis missed and on the list was the most likely and the one that you treated for, then it is better to be able to show that you thought about other possibilities. At the very least you show yourself to be a concerned and caring clinician rather than one that couldn’t be bothered.

Isabel Could Have Improved the Differential Diagnosis in These Cases

Posted by Jason Maude on Mon, Jun 10, 2013 @ 07:08 AM

“Old GP” is an actual GP based in North America who is close to retirement. He has a keen interest in strange presentations of diagnoses and a wealth of experience. He has been using Isabel over the last few months and has gone back over some memorable old cases to see whether and how Isabel could have helped. We thought that his experiences would be of great use and interest to other clinicians, not only to hear about these cases but also how Isabel could have helped in building the differential diagnosis. “Old GP” wishes to remain anonymous out of respect for the privacy of patients and colleagues.

Differential Diagnosis – The Crucial Trigger for Thinking Better

Posted by Jason Maude on Wed, Apr 17, 2013 @ 05:21 AM

The Isabel project was inspired after my own daughter’s near fatal misdiagnosis in 1999. Last week I experienced my own misdiagnosis. Although far less serious, the episode is probably as instructive for the lessons it teaches. It showed me how easy it is to happen, how it’s often nothing to do with lack of time but just down to sloppy thinking. The discipline of doing a differential diagnosis (even for what seems a blindingly obvious, straightforward diagnosis) is crucial to avoid the sloppy thinking traps.

Differential diagnosis needs documenting in primary care shows paper

Posted by Jason Maude on Thu, Feb 28, 2013 @ 01:09 PM

A landmark article published yesterday in “JAMA Internal Medicine” entitled “Types and Origins of Diagnostic Errors in Primary Care Settings” once again highlights the importance and value of traditional clinical skills and the differential diagnosis.

The study looked at 190 cases of diagnostic error highlighted by triggers within the medical record such as unexpected return visits etc. rather than malpractice suits. The settings were two large sites each with a list size of around 50,000 patients-one was public health (Veterans Administration) and the other an integrated private healthcare system. The key points from the paper for us were:

Differential Diagnosis - Who uses Isabel and When? Ambulatory setting

Posted by Dawn Bonsor on Fri, Feb 01, 2013 @ 11:58 AM

As Isabel is sometimes regarded as ‘disruptive’, we thought that an overview of “who” uses Isabel and “when” would be helpful to both current  and future Isabel users to understand how it can often make a major significant impact in patient outcomes with no negative impact on workflows.  This is the first in a series of three blog posts.  Below is a synopsis of “who” uses Isabel followed by instances of “when” they use it. We thought the best way to illustrate this would be to provide some actual cases.  The series will look at the ambulatory, emergency and inpatient settings.  Today’s blog post will cover some cases that came from the ambulatory setting and how diagnostic decision support (DDS) helped them.

Isabel is currently mainly used by:

  • Physicians and PA’s in ED’s, hospitals, urgent care clinics and Physician practices
  • Nurse Practitioners
  • Medical Schools
  • Residency Programs
  • Nursing Schools
  • Legal and risk management teams
