The effects of crew resource management on teamwork and safety climate at Veterans Health Administration facilities

Based on 1984 data developed from reviews of medical records of patients treated in New York hospitals, the Institute of Medicine estimated that up to 98,000 Americans die each year from medical errors. The basis of this estimate is nearly 3 decades old; herein, an updated estimate is developed from modern studies published from 2008 to 2011. A literature review identified 4 limited studies that used primarily the Global Trigger Tool to flag specific evidence in medical records, such as medication stop orders or abnormal laboratory results, which point to an adverse event that may have harmed a patient. Ultimately, a physician must concur on the findings of an adverse event and then classify the severity of patient harm. Using a weighted average of the 4 studies, a lower limit of 210,000 deaths per year was associated with preventable harm in hospitals. Given limitations in the search capability of the Global Trigger Tool and the incompleteness of medical records on which the Tool depends, the true number of premature deaths associated with preventable harm to patients was estimated at more than 400,000 per year. Serious harm seems to be 10- to 20-fold more common than lethal harm. The epidemic of patient harm in hospitals must be taken more seriously if it is to be curtailed. Fully engaging patients and their advocates during hospital care, systematically seeking the patients' voice in identifying harms, transparent accountability for harm, and intentional correction of root causes of harm will be necessary to accomplish this goal.

To describe how communication failures contribute to many medical mishaps. In late 1999, a sample of 26 residents stratified by medical specialty, year of residency, and gender was randomly selected from a population of 85 residents at a 600-bed U.S. teaching hospital. The study design involved semistructured face-to-face interviews with the residents about their routine work environments and activities, the medical mishaps in which they recently had been involved, and a description of both the individual and organizational contributory factors. The themes reported here emerged from inductive analyses of the data. Residents reported a total of 70 mishap incidents. Aspects of "communication" and "patient management" were the two most commonly cited contributing factors. Residents described themselves as embedded in a complex network of relationships, playing a pivotal role in patient management vis-à-vis other medical staff and health care providers from within the hospital and from the community. Recurring patterns of communication difficulties occur within these relationships and appear to be associated with the occurrence of medical mishaps. The occurrence of everyday medical mishaps in this study is associated with faulty communication; but, poor communication is not simply the result of poor transmission or exchange of information. Communication failures are far more complex and relate to hierarchical differences, concerns with upward influence, conflicting roles and role ambiguity, and interpersonal power and conflict. A clearer understanding of these dynamics highlights possibilities for appropriate interventions in medical education and in health care organizations aimed at improving patient safety. Show more
