Addressing Diagnostic Error: Creating Reliable Systems for Diagnosis and Tracking in Primary Care

Transcription

1 Addressing Diagnostic Error: Creating Reliable Systems for Diagnosis and Tracking in Primary Care IHI Workshop 12/6/16 Gordon Schiff, MD, Associate Dir Brigham & Women s Ctr for Patient Safety Research and Practice, Assoc Professor Medicine at Harvard Medical School Lindsay Hunt, MEd, Director of Systems Transformation, Harvard Medical School Center for Primary Care Dan Cohen, MD, Chief Medical Officer, Datix Ltd (UK) and Datix Inc (USA) Mark Graber, MD, Founder, Society to Improve Diagnosis in Medicine

2 Objectives Understand the broad range of human factors that interfere with and degrade diagnostic accuracy and timeliness. Identify patient-centered processes to enhance collaborative efforts of clinicians and patients regarding performance, systematic tracking and follow-up of appropriate screening and diagnostic testing. Identify specific changes to test to create more reliable processes at your own organizations.

8 Definition of Diagnostic Error The failure to: (a) establish an accurate and timely explanation of the patient s health problem(s) or (b) communicate that explanation to the patient The single biggest problem in communication is the illusion that it has taken place. George Bernard Shaw

9 8 IOM Goals to Improve Diagnosis and Reduce Diagnostic Error GOAL 1 GOAL 2 GOAL 3 GOAL 4 Facilitate more effective teamwork in the diagnostic process among health care professionals, patients, and their families Enhance health care professional education and training in the diagnostic process Ensure that health information technologies support patients and health care professionals in the diagnostic process Develop and deploy approaches to identify, learn from, and reduce diagnostic errors and near misses in clinical practice

10 8 IOM Goals to Improve Diagnosis and Reduce Diagnostic Error GOAL 5 GOAL 6 GOAL 7 GOAL 8 Establish a work system and culture that supports the diagnostic process and improvements in diagnostic performance Develop a reporting environment and medical liability system that facilitates improved diagnosis through learning from diagnostic errors and near misses Design a payment and care delivery environment that supports the diagnostic process Provide dedicated funding for research on the diagnostic process and diagnostic errors

11 Genius diagnosticians make great stories, but they don't make great health care. The idea is to make accuracy reliable, not heroic Don Berwick Boston Globe 7/14/

13 What is a Diagnosis Error? Adverse Outcomes Delayed, Missed, Misdiagnosis Diagnostic Process Failures Modified from Schiff Advances in Patient Safety AHRQ 2005, Schiff & Leape Acad Med 2012

14 2 Key Improvement Concepts Situational Awareness Safety Nets

15 Diagnostic Risk Situational Awareness Specialized type of situational awareness High reliability organizations/theory High worry anticipation of what can go wrong Preoccupied w/ risks recognizing/preventing Appreciation diagnosis uncertainty, limitations Limitations of tests, systems vulnerabilities Knowing when over head need for help Making failures visible Don t miss diagnoses, red flag symptoms Diagnostic pitfalls potentially useful construct 15

16 Perhaps the most important distinguishing feature of high-reliability organizations is their collective preoccupation with the possibility of failure. They expect to make errors and train their workforce to recognize and recover them. They continually rehearse familiar scenarios of failure and strive hard to imagine novel ones. Instead of isolating failures, they generalize them. Instead of making local repairs, they look for system reforms Reason Human error: models and management West J Med. 2000;

17 Diagnostic Risk Safety Nets Recognizing inherent uncertainties/risks, build in mitigation, protections, recovery structures and processes Proactive, systematic follow-up, feedback via closed loop systems Major role for HIT to hard-wire To automate, ensure reliability, ease burden on staff/memory, ensure loops closed and outliers visible 17

21 The Problem of Cognitive Bias 21

22 Human Factors Why they are important The processes of healthcare rely on personnel interacting with structures, technologies and with other individuals to achieve outcomes Human factors are those elements that affect each individual s ability to work within structures and to implement the processes effectively Many human factors are well characterized but others may be less apparent, yet compelling in their effects

23 Human Factors Stuff that helps or hinders performance Psychological, physical characteristics of user Relationship between users and broad environment Workspace/noise/temperature/alarms Ergonomics: human technology/equipment interface Stressors not often appreciated Hidden factors Social pressures Economic pressures Management/admin pressures Staff - collegiality/teaming/conflicts/personalities Hunger/fatigue/task saturation/workload

24 Emergency Room Delayed Diagnosis

25 A Story to Start 4 year-old child with fever/lassitude/urinary frequency/history of urinary tract infections Triage nurse orders lab studies per protocol/places child in non-urgent queue Child seen by ED physician two hours later Additional history of maternal sickle cell trait/polyuria Lab studies never performed/physician not alerted Child deteriorates/noted to have sweet odour to breath Dx Hgb S/C disease, diabetic ketoacidosis, pneumococcal sepsis Child nearly dies possibly due to delayed diagnosis

26 The Contributing Hidden Human Factors What the first investigation found The beatings will continue until morale improves! What a deeper dive found

27 Dissecting Diagnostic Errors/Delays Clinicians do not plan to harm patients Well-trained professionals make mistakes every day Diagnostic errors/delays arise from insufficiencies in structures, processes and human performance Accurate/timely Diagnosis is dependent on collaboration between professionals and patients Safety Investigations should focus on structures and processes, and human factors Safety Investigations are about learning, improving safety and most of all. about improving outcomes

29 AIC CARES Aims 1. Continue practice transformation towards high functioning interdisciplinary teams. 2. Prevent missed and delayed diagnoses of colorectal and breast cancer, OR: Reduce the gap between positive developmental screen to completion of a referral for children ages Create new systems and processes for integration of care for patients at high risk for patient safety harms. 4. Train multi-disciplinary teams of leaders capable of spreading and facilitating spread.
