To that end, we\u2019ve split our Action Planning Subcommittee into two groups: Diagnostic Error and Patient Safety Culture, in an effort to divide and conquer. Below, Karen Markwith of Virginia Mason, one of the members of the Diagnostic Error group chaired by Randy Moseley, explains the importance of diagnostic accuracy as it pertains to patient safety and why we\u2019ve chosen it as a focus.<br \/>\n<\/em><\/span><\/p>\n<p><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">There are two decisions you need to make when first taking up archery: Which type of archery are you interested in, and which bow will work best for you? These two decisions will provide you with an increased chance of accuracy in hitting the target or bullseye. The goal of accurately diagnosing a patient\u2019s condition is similar to an archer\u2019s goal of hitting the bullseye.<\/span><\/p>\n<blockquote><p><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\"><strong><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">The Institute of Medicine\u2019s (IOM) committee\u2019s definition of diagnostic error is as follows:<\/span><\/strong> The failure to (a) establish an accurate and timely explanation of the patient\u2019s health problem(s) or (b) communicate that explanation to the patient (NAS).<\/span><\/p><\/blockquote>\n<p><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">Unfortunately the lack of an accurate diagnosis is more common than we realize and can result and serious harm; even death.<\/span><\/p>\n<p><strong><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 12pt; color: #e6a062;\">WHAT THE RESEARCH SAYS<\/span><\/strong><\/p>\n<p><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">Using varied methodologies, studies have found the following:<\/span><\/p>\n<ul>\n<li><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\"><strong>Major diagnostic errors<\/strong> that may have contributed to the patient death have been detected in <strong>10% of autopsies<\/strong><a href=\"#_ftn1\" name=\"_ftnref1\"><sup>[1]<\/sup><\/a><\/span><\/li>\n<li><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">In hospitals, an estimated <strong>7%-17% of adverse events <\/strong>result from diagnostic errors, based on studies of retrospective record reviews<a href=\"#_ftn2\" name=\"_ftnref2\"><sup>[2]<\/sup><\/a><\/span><\/li>\n<li><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\"><strong>At least 1 in 20 adults experiences a diagnostic error each year<\/strong>, based on studies in U.S. outpatient settings<a href=\"#_ftn3\" name=\"_ftnref3\"><sup>[3]<\/sup><\/a><\/span><\/li>\n<li><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">Inaccurate or delayed diagnoses can also have repercussions beyond a single episode of care and cause <strong>ripple effects <\/strong>in the form of inaccurate treatment plans, adverse health events, and psychological and financial consequences.<\/span><\/li>\n<\/ul>\n<p><strong><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 12pt; color: #e6a062;\">TARGETS TO AIM TOWARD<\/span><\/strong><\/p>\n<p><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">The IOM published a report in 2015 on diagnostic errors and the need to improve diagnosis.<a href=\"#_ftn4\" name=\"_ftnref4\"><sup>[4]<\/sup><\/a> According to the report, to improve diagnosis is a \u201cmoral, professional, and public health imperative.\u201d \u00a0The report identified eight overarching goals and many supporting recommendations.

Communication among all members of the team must be timely and effective as well as clearly documented in the medical record, according to the IOM report. To improve teamwork, the breaking of silos and paradigms among members of the diagnostic team is also an innovative step in increasing accuracy. For example, integrating laboratory staff into assisting with what type of test should be run could assist a clinician when unsure of which tests are best suited to the clinical problem or how to interpret results. Contributions from other healthcare professionals can be value-added to improve the diagnostic process through their monitoring of the patient condition and the sharing of observations concerning the patient\u2019s response to treatment.<\/span><\/p>\n<p><strong><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 12pt; color: #e6a062;\">ACCOUNTING FOR BIAS: THE WIND FACTOR OF DIAGNOSIS<\/span><\/strong><\/p>\n<p><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">Obtaining a variety of information also helps support the reduction of inherent bias, or what is often referred to as cognitive bias, that can contribute to an inaccurate diagnosis as well. Cognitive biases are a universal feature of human cognition like system errors for the brain. Understanding the contribution of cognitive bias and the interaction of bias with system errors and how they may produce bad outcomes should be part of the education and training regarding the improvement of accuracy in the diagnostic process. According to Graber et al (2015), \u00a0when conceptualizing cognitive error whenever a patient is harmed in relation to the diagnostic process, two broad categories of causal factors should be considered:<a href=\"#_ftn5\" name=\"_ftnref5\"><sup>[5]<\/sup><\/a><\/span><\/p>\n<p><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">1) <strong>The \u201cBlunt End\u201d<\/strong> \u2014 All the system-related elements that contribute to diagnosis.<\/span><\/p>\n<p><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">2) <strong>The \u201cSharp End\u201d<\/strong> \u2014 All the cognitive factors.<\/span><\/p>\n<p><a href=\"https:\/\/www.qualityhealth.org\/wpsc\/wp-content\/uploads\/sites\/3\/2018\/07\/Arrow.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-5644\" src=\"https:\/\/www.qualityhealth.org\/wpsc\/wp-content\/uploads\/sites\/3\/2018\/07\/Arrow-1024x344.jpg\" alt=\"Arrow\" width=\"600\" height=\"201\" \/><\/a><\/p>\n<p><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">Cognitive bias also can produce anchoring, which is the tendency to rely too heavily on the initial piece of information offered when making decisions. In this case, we risk starting from an initial impression and failing to adjust appropriately. The concept of anchoring when applied to the diagnostic process is the tendency to perceptually lock on salient features in the patient\u2019s initial presentation too early in the diagnostic process, and fail to adjust this initial impression in light of later information.<\/span><\/p>\n<p><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\"><strong>Common \u201canchors\u201d that can contribute to an inaccurate diagnosis:<\/strong><\/span><\/p>\n<ul>\n<li><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">Billing codes<\/span><\/li>\n<li><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">Reason for consultation<\/span><\/li>\n<li><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">Problem lists<\/span><\/li>\n<li><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">Previous admissions<\/span><\/li>\n<li><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">Old diagnosis-new problem<\/span><\/li>\n<li><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">Previous provider notes<\/span><\/li>\n<\/ul>\n<p><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">These are just a few examples of what could easily be a longer list. The key component is awareness of the concept of \u201canchoring\u201d and ensuring that these cognitive biases do not contribute to a diagnostic error.<\/span><\/p>\n<p><strong><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 12pt; color: #e6a062;\">LEARNING FROM ERRORS AND NEAR MISSES<\/span><\/strong><\/p>\n<p><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">An example of the #4 goal \u2014 identification of errors and near misses and efforts to learn from and reduce them \u2014 is understanding the value of a near miss. Near misses are the best signal that something is not right and needs some dedicated attention before the error reaches the patient. One of the most latent near misses that needs a more rigors process is how a clinician addresses \u201cmissed labs\u201d by the patient as well as lab results that are narrowly missing the high or low parameters of the diagnostic test. Paying attention to near misses and using them as \u201cteaching moments\u201d can help redesign work systems that support team member involved in the diagnostic process.<\/span><\/p>\n<p><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\">Just as the right tools for archery can increase the likelihood of reaching the target, the right goals can help clinicians increase their accuracy with patient diagnosis. As a patient, I want my healthcare professionals to hit the bullseye every time!<\/span><\/p>\n<p><strong><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 12pt; color: #e6a062;\">ABOUT THE AUTHOR<\/span><\/strong><\/p>\n<p><span style=\"font-family: 'Century Gothic', CenturyGothic, AppleGothic, sans-serif; font-size: 10pt;\"><strong><a href=\"https:\/\/www.qualityhealth.org\/wpsc\/wp-content\/uploads\/sites\/3\/2018\/07\/Karen-Markwith.png\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-5640 size-thumbnail alignleft\" src=\"https:\/\/www.qualityhealth.org\/wpsc\/wp-content\/uploads\/sites\/3\/2018\/07\/Karen-Markwith-150x150.png\" alt=\"Karen Markwith\" width=\"150\" height=\"150\" \/><\/a>Karen Markwith<\/strong>, RN, MJ, CPHRM, CHPS is the Director of Quality and Patient Safety at Virginia Mason Medical Center.
