Background: In patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary interventions (pPCI), longer door-to-balloon (DTB) time is known to be associated with an unfavorable outcome. A percentage of patients with acute coronary occlusion present with atypical electrocardiographic (ECG) findings, known as STEMI-equivalents. We investigated whether DTB time for STEMI-equivalent patients was delayed. Methods: This is a retrospective study including patients arriving at an emergency department with the acute coronary syndrome in whom emergent pPCI was performed. ECGs were classified into STEMI and STEMI-equivalent groups. We compared DTB time, with its components, between the groups. We also investigated whether STEMI-equivalent ECG was an independent predictor of DTB time delayed for more than 90 min. Results: A total of 180 patients were included in the present study, and 23 patients (12.8%) presented with STEMI-equivalent ECGs. DTB time was significantly delayed in patients with STEMI-equivalent ECGs (89 (80–122) vs. 81 (70–88) min, p = 0.001). Multivariable logistic regression analysis showed that STEMI-equivalent ECG was an independent predictor of delayed DTB time (odds ratio: 4.692; 95% confidence interval: 1.632–13.490, p = 0.004). Conclusions: DTB time was significantly delayed in patients presenting with STEMI-equivalent ECGs. Prompt recognition of STEMI-equivalent ECGs by emergency physicians and interventional cardiologists might reduce DTB time and lead to a better clinical outcome. [ABSTRACT FROM AUTHOR]

Aims and objectives: This study aimed to develop a fall risk perception questionnaire for patients admitted to acute care hospitals and to establish its reliability and validity. Background: To prevent falls during patients' hospitalisation, it is essential for them to accurately perceive their risk of falling. Design: This methodological study was performed to develop a fall risk perception questionnaire. Methods: After generating a preliminary questionnaire, two rounds of content validity testing were performed with nine experts. Following a pilot test, a convenience sample of 236 participants was recruited from an acute care hospital between 2 May 2018 and 15 December 2019. Construct, convergent and known‐group validity of the questionnaire was evaluated, and reliability was estimated by calculating the internal consistency reliability coefficients. The study adhered to STROBE guidelines. Results: Exploratory factor analysis yielded a three‐factor solution with 27 items. The questionnaire showed statistically significant positive correlation with the Korean Falls Efficacy Scale‐International and the Morse Fall Scale, thus establishing convergent validity. For known‐group comparison, Morse Fall Scale scores were categorised into two groups by cut‐off score. The risk for falls group had a significantly higher perceived fall risk than the no risk for falls group, thus establishing known‐group validity. Cronbach's alpha values indicated good to excellent reliability for the overall questionnaire with 27 items and for each of the three subfactors. Conclusions: The fall risk perception questionnaire demonstrated satisfactory reliability and validity in an acute care hospital setting. Relevance to clinical practice: Because understanding patients' perceptions of their fall risk is essential for preventing falls, it is necessary to regularly assess patients' fall risk perception using tools with established reliability and validity.

In attempted suicide, laryngotracheal rupture caused by hanging leads to rapid death at the scene or before arrival at hospital. The case presented here describes a patient with complete tracheal rupture from an attempted suicidal hanging who was successfully resuscitated. Pre-hospital providers transferred the patient to hospital without being aware of the possibility of airway damage. Cardiac arrest occurred shortly after arrival at hospital. During the cardiopulmonary resuscitation, endotracheal intubation was performed, and fortunately, the tracheal tube was located just below the ruptured trachea and thus enabled ventilation. For patients suspected of having airway damage at the pre-hospital stage, awareness of the patient's condition and adequate airway management are important. The management of laryngotracheal rupture which suggests that for patients not adequately ventilated, immediate treatment with flexible fiberoptic intubation or tracheostomy is needed to secure the airway. Equipment and personnel at the receiving hospital need to be prepared for immediate treatment. [ABSTRACT FROM AUTHOR]
