Cause Of Human Error

from expected behavior. Under normal conditions, we can make between three to seven errors per hour. Under stressful, emergency, or unusual conditions, we can make an average of human error not root cause 11 errors per hour. But why do we make errors? Is it the human error and root cause analysis individual’s fault? A recent presentation by the Idaho National Laboratory showed following: Latent organizational weaknesses include work processes, and, as reasons for human error the above shows, such work processes usually are behind human error. Why did the error occur? The procedure wasn’t followed. Why? Human error. Why was there human error? The work process needs improvement. causes of human error in the workplace Sometimes, human error proves just how good some workers are. At the beginning of a root cause analysis, it’s not uncommon to hear someone say: “Bob has been calibrating these instruments for 20 years and he just screwed up.” Though it may seem like finger-pointing, it’s actually the ultimate compliment, and the incident investigation facilitator should recognize it. Think about the math. Bob has performed this

task twice a week, 100 times a year for 20 years. That’s 2,000 calibrations—and this is his first significant error? Error rates of just 1/1000 are considered exceptional, and Bob beat this by a long shot. Does this warrant a root cause analysis at all? It may, because incidents rarely if ever have just one cause. Are we absolutely sure that Bob’s mistake was the only reason the incident occurred? Dig deeper and you likely will find there’s more to the problem than Bob’s once-in-an-eon snafu. Beyond Blame If we stop at “Procedure Not Followed,” the usual response is to blame a person. Blame is easy and does not focus on the process. Let’s face it—“Procedure Not Followed” is a simple (albeit oversimplified) explanation of confusing and complex problems. It also requires little or no work from anyone in an organization except the person who made the mistake. How does this make the person feel? Not listened to, unappreciated and, eventually, apathetic, which isn’t good for anybody. The key to getting beyond the procedure-not-followed conundrum in a root cause analysis is obtaining detail, and it’s here where the Cause Mapping facilitator plays a key role. During

Each has its model of error causation and each model gives rise to quite different philosophies of error management. Understanding http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1117770/ these differences has important practical implications for coping with the ever present risk of mishaps in clinical practice. Summary pointsTwo approaches to the problem of human fallibility exist: the person and the system approachesThe person approach focuses on the errors of individuals, blaming them for forgetfulness, inattention, or moral weaknessThe system approach concentrates on the conditions under which individuals work and tries to build defences to avert errors or mitigate their effectsHigh reliability organisations—which have less than their fair share of accidents—recognise that human variability is a force to harness in averting errors, but they work hard to focus that variability and are constantly preoccupied with the possibility of failurePerson approachThe longstanding and widespread tradition of the person approach focuses on the unsafe acts—errors and procedural violations—of people at the sharp end: nurses, physicians, surgeons, anaesthetists, pharm
“typical response to a human error is retraining. But studies have now shown that training —or lack thereof—is responsible for only about 10 percent of the human errors that occur. Despite [an increased] awareness of http://pilgrimquality.com/blog/root-cause-analysis-and-human-factors/ human errors, companies still frequently fail to substantively and correctly address errors.” Companies often turn to training, or retraining, as a quick and easy solution for a human error, when the real cause may be a deeper, systemic issue that could be revealed through root cause analysis (RCA). “Training is thrown at problems when it is not even known what the real problem is—or the root cause of the problem,” says the FDA. human error In fact, “instead of helping, retraining can sometimes make a bad situation worse.” George Bernstein, a root cause analysis expert with MAI Consulting (www.consultmai.com) in North Carolina, indicates the most common root cause for a human error is not following procedure and the most common corrective action is retraining. “While this may in fact be the root cause,” he cautions, “if the problem has been repeated numerous times within the past year or so of human error with the same person, the problem may be ineffective training. If the problem is a repeat with a number of people, the problem may be inadequate instructions. Trending of deviations is essential to verify that the root cause was correctly identified.” The FDA warns that quality control staff should be wary about listing “retraining” as a corrective action in an FDA investigation unless they are absolutely certain that is the case. “By indicating that retraining is being done to correct a problem, they are also pointing out the fact that the original training effort was less than effective,” writes the FDA (which may not actually be true). Root cause analysis, when properly implemented, is a comprehensive method of investigation that identifies the sequence of events that resulted in an adverse incident or a human error. Different human error categories are: Procedure-related errors Human factor engineering related error Training-related error Error reduction Supervision-related error Communications-related error Individual error At first glance the cause of a human error may seem obvious, followed then by the hasty conclusion that training or retraining can fix it. However, a complete RCA investigation often reveals a much deeper issue is to blame. “If only the top levels of an event (human error or equipment failure) are investigated, only one problem will be solved,” says
