This study investigated failures of prospective memory (PM) as a relevant but neglected error type in medicine. A patient simulator was used to investigate PM failures. The influence of subjective importance (high, low) and type of intention (educational, internal, external) on the (missed) execution of intention was investigated in a 2 x 2 design. The effects on missed executions by importance (high < low) and type of intention (educational < external < internal) were hypothesized. Of 73 valid intentions in 40 prepared simulator scenarios 19 (26%) were missed overall. A total of 64% of unimportant and 80% of important intentions were executed 79% of educational 67% of external and 72% of internal intentions were executed. Neither difference was statistically significant using chi(2) tests. Interaction was significant for missed executions (p = 0.025; n = 19; df = 2; chi(2) = 7.41) and for executions (p = 0.002; n = 54; df = 2; chi(2) = 12.50). Despite low statistical support and some methodological limitations, it was possible to show that PM failures are relevant to patient safety and that patient simulators are a suitable but so far unused tool for their investigation.
BackgroundChest compressions are a core element of cardio-pulmonary resuscitation. Despite periodic training, real-life chest compressions have been reported to be overly shallow and/or fast, very likely affecting patient outcomes. We investigated the effect of a brief Crew Resource Management (CRM) training program on the correction rate of improperly executed chest compressions in a simulated cardiac arrest scenario.MethodsFinal-year medical students (n = 57) were randomised to receive a 10-min computer-based CRM or a control training on ethics. Acting as team leaders, subjects performed resuscitation in a simulated cardiac arrest scenario before and after the training. Team members performed standardised overly shallow and fast chest compressions. We analysed how often the team leader recognised and corrected improper chest compressions, as well as communication and resuscitation quality.ResultsAfter the CRM training, team leaders corrected improper chest compressions (35.5%) significantly more often compared with those undergoing control training (7.7%, p = 0.03*). Consequently, four students have to be trained (number needed to treat = 3.6) for one improved chest compression scenario. Communication quality assessed by the Leader Behavior Description Questionnaire significantly increased in the intervention group by a mean of 4.5 compared with 2.0 (p = 0.01*) in the control group.ConclusionA computer-based, 10-min CRM training improved the recognition of ineffective of chest compressions. Furthermore, communication quality increased. As guideline-adherent chest compressions have been linked to improved patient outcomes, our CRM training might represent a brief and affordable approach to increase chest compression quality and potentially improve patient outcomes.Electronic supplementary materialThe online version of this article (doi:10.1186/s12873-017-0117-6) contains supplementary material, which is available to authorized users.

Preventing patient harm is one of the main tasks for the field of anesthesiology from early on. With the introduction of the national German incident reporting system PaSOS, which is hosted by the German anesthesia society, anesthesiology is again leading the field of patient safety. Important elements, success factors and background information for the introduction of successful incident reporting systems in an organization are given. Examples by and from PaSOS are given.
