Summary. The use of emergency medical identification (EMI) such as MedicAlert® has been recommended for use in a variety of medical conditions; however, there is no consensus as to what form should be used and where they should be placed. There are also no uniform guidelines to direct first responders to where they should look for EMI in an emergency. The aim of this study was to identify current paediatric haemophilia nursing practice in educating families about EMI and their perceptions of patient/family adherence to using EMI. US haemophilia nurses listed on the Center for Disease Control’s website received an email invitation to participate in a 30‐item questionnaire posted on SurveyMonkey. Survey responses showed a wide variety of responses concerning recommendations about the form and location of EMI, particularly in the infant population. Nurses also reported that EMI was often not worn on the body and had low overall adherence. In the infant and preschool population, this was due to safety concerns, sizing, cost and parents not seeing the need for EMI. In school age and adolescents, the barrier to wearing EMI included stigma, cost and sizing. Collaboration is needed among nursing and medical staff, first responders, emergency room staff and manufacturers of EMI to develop standardized EMI which address these issues. Standard educational guidelines are needed to teach nurses and patient/families about the forms and location of EMI. Additionally, national guidelines are needed for the identification of paediatric EMI by first responders and emergency room staff. 相似文献

Objective. To evaluate the ability of paramedics to learn and apply the skill of introducer-aided oral intubation in the setting of the simulated “difficult airway.” The authors hypothesized that, following a brief introduction to the device, intubation success rates would not differ for traditional and introducer-aided intubations of an immobilized airway mannequin. Methods. During a paramedic recertification class, experienced paramedics were given a brief didactic introduction to the “bougie-like” Flex Guide endotracheal tube introducer (ETTI). The participants were then asked to intubate adult mannequins immobilized in the head-neutral position, with and without the ETTI. “Successful placement” was defined as completion of the procedure within 30 seconds and endotracheal tube position confirmed by the investigator with direct visualization. Results. For both traditional and ETTI intubations, 34 (97%) of the 35 paramedics successfully intubated within 30 seconds. The two unsuccessful intubation attempts were recognized by the paramedic as esophageal intubations, and correct tube placement was obtained within an additional 30 seconds. Conclusion. In this study, use of the ETTI was mastered by the participants after only a brief didactic introduction to the device, with their ability to intubate an immobilized mannequin using the ETTI being equal to their ability to perform traditional intubation. These results suggest that use of the ETTI is easily learned, and may support the device's role in the prehospital management of the difficult airway. 相似文献

Objective To prospectively compare a modified pneumonia severity scoring system, SMARTACOP, with other severity scores in patients presenting with pneumonia to the emergency department (ED) of a tertiary referral hospital in tropical Australia. Methods We conducted a prospective observational study of adult patients presenting with radiologically confirmed pneumonia over a 12‐month period. The sensitivity of risk stratification scores were assessed against the need for intensive respiratory or vasopressor support (IRVS). Results There were 367 ED attendances for pneumonia of whom 77.1% were admitted to hospital, 10% required intensive respiratory or vasopressor support and 2.8% died. Mean age was 50.0 years, 52% were men and 59% were Indigenous. The sensitivity of a SMART‐COP score ≥3, a SMARTACOP score ≥3 and a pneumonia severity index (PSI) class ≥3 for predicting IRVS was 97%, 97% and 78% respectively. Conclusions We found no significant advantage of the SMARTACOP over the SMART‐COP score for the prediction of intensive respiratory or vasopressor support, but both scores significantly outperformed PSI. The SMART‐COP score should replace the PSI in tropical Australia and should be assessed in other tropical areas for pneumonia risk stratification in emergency departments. 相似文献
