Dear all,

I too have been following the very interesting discussion on this list.  And I have also been following the discussions for years on the National Patient Safety Foundation list, as I am sure many of you do.

I have realized that on these two lists we talk at length about the problems but very little about what is or should be done to solve the problems. 

Here we have 100,000 - 210,000 (or whatever the upper figure is) dying each year and still more maimed or injured. And I ask what have we done since the IOM report on Errors issued nearly 15 years ago?  http://www.iom.edu/~/media/Files/Report%20Files/1999/To-Err-is-Human/To%20Err%20is%20Human%201999%20%20report%20brief.pdf  

? And many think that the situation has become worse - hence my 210,000 upper figure  http://www.npr.org/blogs/health/2013/09/20/224507654/how-many-die-from-medical-mistakes-in-u-s-hospitals 210,000 is something like the 3rd, 4th, or 5th, cause of death in the US. That we cannot get significant funding for this is beyond comprehension and disgusting.

With the NPSF list that serves the hospitals of the nation hardly anyone talks about solutions or research taking place in their hospitals to create changes. Presumably for fear of losing or compromising their jobs because significant change might impact the bottom line - and I realize that may be harsh thinking.

Further, there seems a reluctance to talk about advances in the private sector, presumably for proprietary reasons relating to copyrights and patents. 

And then moving to the academic area of endeavor, the same reluctance to talk about what research is ongoing and what advances are being made, presumably for academic reasons associated with the secrecy surrounding the "publish or perish" mantra.

Unless I am missing a lot the situation to me seems to be an all around disaster. Surely, with the level deaths and injury we need to be at constant war with this problem. Surely there needs to be the equivalent of a national war room with a coordinated strategy?

Is there an up to date State of the Union Report that I am not aware of; are there significant plans in the works, both national government and societies that I am not aware of; is there already the equivalent of a national war room with intense planning taking place; does academia have a national or even global plan to get on top of things; are there leaders that I am not aware of that are making progress and starting to make change?

I am reminded that Nobel Prize winner Barry Marshall’s work on peptic ulceration and H. pylori took roughly 20 years for antibiotic treatment to be accepted into USA clinical practice as standard therapy  http://en.wikipedia.org/wiki/Barry_Marshall  So, even if a breakthrough in Errors came it would not be fully accepted by all for many years with more dying and injured needlessly.

What I would like to see is a list of priorities to reduce errors at all levels in the healthcare system, with each priority discussed as to the various ways that change can quickly be effected. Perhaps there is one, if not, which organization would be best to make one?

Sorry to be so blunt, but how many died while typing this? If half an hour it would have been about 12 if at the above 210,000 level a year - and whose relatives are these?

Teach people to be systematic, to appropriately use the available tools, and to calibrate their intuitive approaches with better numerical literacy and probability estimates.  Focusing on errors doesn’t seem like a very fruitful path forward.
>> 	Anecdotes and patient stories can motivate us to improve, but don’t necessarily give us the lessons on how to improve. And measuring diagnostic error rates will always be difficult in the real world. No doubt, the studies that have estimated the error rates are important for raising public awareness and motivating our efforts. Diagnostic errors occur way too commonly. But measuring diagnostic error rates will be always be problematic for analysis of individual performance over time. Effective practitioners seek follow up, measurement and feedback for internal use, but external reporting of error rates could have lots of unintended consequences.
>> 	Measuring diagnostic skill is like measuring fielding in baseball. Baseball uses fielding percentages, but we know that that measure is flawed. A player can improve his fielding percentage by limiting his range. Likewise, a hospitalist can lower his/her error rate by consulting on every patient and ordering lots of tests, which in effect limits his/her range and is very inefficient. And certain positions, like first base, have a better chance of getting a higher fielding percentage. Likewise, certain medical specialties have a better chance of avoiding diagnostic error than others. Also, to measure fielding percentage, you have to track every single opportunity, which is virtually impossible in clinical medicine. This email string is a testament to the difficulties in defining errors and tracking opportunities.
>> 	So, in my humble opinion, we need to focus on education efforts, to help practitioners and patients develop better diagnostic habits, and facilitate the consistent use of these good habits.

>> If all we focus on is the miss or delay rate, we will fail to appreciate the harm that can come by over diagnosis and over treatment. Take a theoretical and extreme example for illustrative purposes:
>> --Doctor A obtains a CT scan on every patient with RLQ pain across the board to make sure appendicitis is not missed. Still may miss a case or 2 over the course of several years due to the intrinsic miss rate of CTs
>> --Doctor B does a selective approach. Using his judgment and sometimes guided by labs, he sometimes will do a CT, sometimes will recommend a clinical recheck the next day, or sometimes tells the patient everything looks fine today and come back as needed for worsening.  In doing this, he may miss a few more cases of appendicitis over the years than Doctor A but avoids hundreds of unnecessary CT scans.
>> 
>> So if the only variable studied is how often a diagnosis is missed, Doctor A will always come out on top when in the more complete picture his overtesting and overtreating style can lead to greater public harm not only through greater cost but also through radiation exposure, adverse medication reactions, drug resistance, and so on.  
>> 
>> I am sure we are going to see an explosion of studies looking at how often diagnoses are missed or delayed. I gather the majority will be retrospective studies - at least in these early phases. My fear is that retrospective analysis has many limitations and unmeasured variables, yet it is going to be the results rather than the limitations that will receive greater public attention. Ultimately, this evolving science about how to improve diagnostic efficacy is going to have to balance the harm that can come by both under and over diagnosis. I hope the caution expressed by Eric that we are a long way from safely implementing performance metrics and regulations is heard widely and embraced strongly.

>> 
>> In some of the research I have done with Hardeep Singh, we have tried to use definitions of diagnostic errors that allow a reliable and valid measurement to occur.  We mostly avoided the issue of diagnoses that evolve over time.  
>> 
>> In some of our work we used the following definition, “An error was judged to have occurred if adequate data to suggest the final, correct diagnosis were already present at the index visit or if the documented abnormal findings at the index visit should have prompted additional evaluation that would have revealed the correct, ultimate diagnosis.  Thus, errors occurred only when missed opportunities to make an earlier diagnosis occurred based on retrospective review.”  The “index visit” is the visit we sampled for review.  I won’t get into all the details here, but this definition was used for a study where we sampled primary care visits which preceded an unexpected return visit to the primary care office or the ED.
>> 
>> So, when that definition is used we are pretty much eliminating the cases that are evolving over time.  We called it a dx error when all the data was there at the time of the visit to make the right dx.  As a practicing primary care doc, I am very sensitive to the fact that diagnoses evolve over time and it is often unclear what the dx is at the time of a single visit.  Our research does not label delays when all the data is not available as an error.
>> 
>> I agree with others that we will never know THE rate of diagnostic error.  However, with good measurement we can come to understand the frequency, types, and contributing factors of dx error within certain practice settings and for certain diseases.  I think a disease-specific and setting-specific approach will lead to the most improvement.
>> 
>> While I have your attention (wishful thinking, I know) I’d also say that we are a very, very long way from measures of dx error that could be useful for any external body (CMS, Leapfrog, etc) to use as some type of publically reported performance measure.  Groups like that have already gone too far with efforts to measure safety – in many organizations those externally mandated, top-down measures create cultures of accountability and even blame such that caregivers end up redefining or even hiding events so they don’t have to be reported to management.  Also, those externally mandated measures only capture a small fraction of all the harm that occurs.  What we need, especially for diagnostic errors, are cultures where learning and improvement are valued.  Externally mandated measures, especially those not based on good science, will not help us reduce diagnostic errors.

>> Statistics
>> Errors related to missed or delayed diagnoses are a frequent cause of patient harm. In 2003, a systematic review of 53 autopsy studies from 1966 to 2002 was undertaken to determine the rate at which autopsies detect important, clinically missed diagnoses. Diagnostic error rates were 4.1% to 49.8% with a median error rate of 23.5%.* Furthermore, approximately 4% of these cases revealed lethal diagnostic errors for which a correct diagnosis coupled with treatment could have averted death.4 Other autopsy studies have shown similar rates of missed diagnoses; one study reported the rate to be between 10% to 12%5, while another placed it at 14%.6 Autopsies are considered the gold standard for definitive evidence of diagnostic error, but they are being performed less frequently and provide only retrospective information.
