Elderly patients are highly susceptible to rib fractures after trauma. The use of a clinical pathway to determine resource allocation for patients with rib fractures has resulted in positive treatment outcomes. This retrospective study assessed the efficacy of a triage protocol involving trauma services on hospital length of stay in elderly patients with fractured ribs. Patients who had 3 or more ribs fractured experienced a statistically significant reduction in hospital length of stay after protocol implementation. We conclude that elderly patients with 3 or more rib fractures should be systematically referred to a trauma specialist.

Our assessments of how much we know about a particular topic can be a}ected by our con_dence in our knowledge[ Research in judgement and decision making has shown that people are generally overcon_dent in their judgements or decisions\ and that this bias can be reduced with training[ We present two studies designed to assess whether debiasing can be accomplished in a classroom setting and whether it has practical value for students[ In Experi! ment 0 simply providing con_dence estimates as questions were answered was enough to debias students in a series of course!related quizzes[ In Experiment 1\ weekly quizzes were given in a computer!administered format[ Students were given feedback for each question as it was completed[ We found that accuracy on quizzes improved as con_dence declined[ We also found that students performed better in the course when they received debiasing training[ We suggest that debiasing training prompted students to develop and use metacognitive skills that allowed them to assess their knowledge more accurately[ Given this\ training for these skills has practical value in the classroom[

Background Early detection of pupillary changes in patients with head injuries can alert the care team to increasing intracranial pressure. Previous research has shown inconsistencies in pupil measurement that are most likely due to the subjective nature of measuring pupils without the assistance of technology. Objectives To evaluate nurses’ abilities to assess pupil diameter accurately and detect unequal pupils. Methods In a 3-part study, the accuracy of critical care and neurosurgical nurses’ assessments of pupils was determined. The study included assessment of drawings of eyes with an iris and pupil, examination of photographs of human eyes, and bedside examination of patients with a head injury. Results Subjective assessments of pupil diameter and symmetry were not accurate. Across all phases of the study, pupil diameters were underestimated and the rate of error increased as pupil size increased. Nurses also failed to detect anisocoria and misidentified pupil reactivity. In addition, nearly all nurses relied on subjective estimation, even when tools were available. Conclusions Critical care and neurosurgical nurses underestimated pupil size, were unable to detect anisocoria, and incorrectly assessed pupil reactivity. Standardized use of pupil assessment tools such as a pupillometer is necessary to increase accuracy and consistency in pupil measurement and to potentially contribute to earlier detection of subtle changes in pupils. If pupillary changes are identified early, diagnostic and treatment intervention can be delivered in a more timely and effective manner.

The elderly individuals are the most rapidly growing cohort within the US population, and a corresponding increase is being seen in elderly trauma patients. Elderly patients are more likely to have a hospital length of stay (LOS) in excess of 10 days. They account for 60% of total ICU days. Length of stay is frequently used as a proxy measure for improvement in injury outcomes, changes in quality of care, and hospital outcomes. Patient care protocols are typically created from evidence-based guidelines that serve to reduce variation in care from patient to patient. Patient care protocols have been found to positively impact patient care with reduced duration of mechanical ventilation, shorter LOS in the ICU and shorter overall hospitalization time, reduced mortality, and reduced health care costs. The following study was designed to assess the impact of the implementation of 4 patient care protocols within an elderly trauma population. We hypothesized that the implementation of these protocols would have a beneficial impact on patient care that could be measured by a decrease in hospital LOS. An archival, retrospective pretest/posttest study was performed on elderly trauma patients. The new protocols helped guide practical changes in care that resulted in a 32% decrease in LOS for our elderly trauma patients which exceeds the 25% decrease found in other studies. Additionally, the "Other" category for each variable was less frequently used in the post-protocol phase than in the pre-protocol phase, suggesting a spillover effect on the level of detail recorded in the patient chart. With less variation in practices in the post-protocol phase, Injury Severity score, and admission systolic blood pressure emerged as significant predictors of LOS.
