Errors in medicine

History
Modern awareness of the problem of medical injury – complications of treatment – can be fairly dated to the publication in 1991 of the results of the Harvard Medical Practice Study [1], [2]. This review of 30,000 medical records of patients hospitalized in New York state showed that 4% of patients had complications of their treatment, which we call adverse events. Even more shocking was the finding that two-thirds of these iatrogenic injuries were due to mistakes and therefore were preventable.
Achieving safe health care
Although the major focus has been on implementing safe practices, it has become increasingly apparent that achieving a high level of safety in our health care organizations requires much more. Several streams have emerged. One of these is the recognition of the importance of engaging patients more fully in their care. Another is the need for transparency. Safety experts and patient advocates agree that patients have a right to know all about their care, especially when things go wrong. Full
What have we learned?
From this relatively short experience, we have already learned a great deal. The most important lesson is that systems theory works. Errors and injuries can, in fact, be prevented by redesigning systems to make it difficult, and sometimes impossible, for caregivers to make mistakes. A classic example is the elimination of accidental (fatal) intravenous injections of concentrated potassium chloride by removing the medication from the nursing units and requiring it to be added to intravenous
A culture of safety
What is a culture of safety? Various authors have defined it in different ways. James Reason emphasizes that a safe culture includes three characteristics. First and foremost it must be a just culture: people are not punished for making errors, but deliberate violations and misconduct are not tolerated. Second, it must be a reporting culture: the environment must be safe for people to talk about errors and report them. Only in that way can we discover our problems and fix them. Finally, it must
Making the changes: the importance of teamwork
Return to the problem of hand hygiene. Most hospitals have a policy requiring everyone, doctors, nurses, technicians, assistants, to disinfect their hands before and after touching a patient. But compliance in most hospitals is dismal. Why? The reason is that we do not work in teams. Compliance is, appropriately, an individual responsibility. But it is more likely to happen when caregivers work together in teams. And most doctors and other caregivers do not know much about working in teams.

The safety challenge in laboratory medicine
In terms of quality control, and error rates specifically, laboratory medicine has a far better record than most other fields in health care. In the analytic phase, some studies indicate that the average error rate is as low as 0.002%. This is functioning at the 5 sigma level. For comparison, the rates of infections and medication errors are closer to 3 sigma, i.e., defect rates > 3000 times those in the laboratory! (Fig. 1).
