Discussion General findings and interpretation We gathered and analysed a large number of unintended www.selleckchem.com/products/3-deazaneplanocin-a-dznep.html events (522) using a root cause analysis tool based on the sound theoretical
frameworks of Reason and Rasmussen, which is accepted by the WHO and which has a good reliability.[27] The results show that a large number of unintended events occur in the collaboration with departments outside the ED (laboratory, radiology, consulting services etc). Staff in the ED are heavily dependent on these services. The Inhibitors,research,lifescience,medical problems in the cooperation with outside services can also be noticed in the phase of care in which unintended events mainly come about -medical examinations and tests-, since a
lot of tests are performed in other departments. Half of all reported events reached the patient directly, most often resulting in inconvenience or suboptimal care. The causes of the unintended events were mainly human, though system selleck chemicals Erlotinib factors (organisational Inhibitors,research,lifescience,medical and technical) were established as well. Predominance by human causes is also found Inhibitors,research,lifescience,medical in the aviation industry. It is estimated that approximately 75 percent of all aviation accidents are related to human errors.[28] Nearly half of all causes we found were external, meaning that an individual’s behaviour, technical factors or organisational factors at an outside department contributed to the unintended event. This also confirms the finding that there are problems in the Inhibitors,research,lifescience,medical cooperation with other departments, although we have to bear in mind that people feel less constrained reporting unintended events originating in other departments than in their own. Unintended events related to materials and equipment were relatively often caused by technical factors. Incorrect data and substitutions were for a relatively large part caused by human errors, while organisational factors contributed most to unintended events related
to protocols and regulations. Some comments have Inhibitors,research,lifescience,medical to be made for a good interpretation of Cilengitide the causes of the unintended events. Firstly, the reported unintended events were related to patient care, and healthcare providers were somehow involved in all events. This resulted in involvement of human causes in many cases. The PRISMA analysis, however, did focus on identifying accompanying system factors, beside these human causes. Secondly, as we strived for objective information about underlying causes, presumptions of the reporters about possible organisational or technical causes were not recorded in the causal tree. Finally, a lack of organisational or technical barriers was not labeled as an organisational or technical cause. An example: when two healthcare providers make the same laboratory request for a patient, blood is taken unnecessarily once.
