[PMID: 38262784 DOI: 10.1016/j.jemermed.2023.10.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Revised: 07/25/2023] [Accepted: 10/01/2023] [Indexed: 01/25/2024]
Abstract
BACKGROUND Patients present to emergency departments (EDs) from a variety of backgrounds, which may help inform decision making. OBJECTIVE This study investigated the clinical characteristics and outcomes of outpatient department (OPD)-referred patients and self-referred patients in the ED. METHODS We selected nontrauma ED adult patients from a tertiary teaching hospital in Taiwan between August 1, 2020, and October 31, 2020. The acuity levels were determined by dichotomizing the triage classification scores. After propensity score matching, we compared the hospitalization, mortality, and length of ED stay of OPD-referred and self-referred patients. We categorized the patients into "emergency" or "urgent" subgroups according to their triage information and then analyzed the effects of different severity levels. Statistical significance was set at p < 0.05. RESULTS A total of 564 OPD-referred and 11,959 self-referred patients were included. After propensity score matching, the OPD-referred patients (n = 564), compared with self-referred patients (n = 564), had a higher admission rate (49.8% vs. 28.9%; p < 0.001; odds ratio [OR] 2.44). Among the emergency subgroup patients, there was no significant difference between OPD-referred patients (n = 131) and self-referred patients (n = 138) regarding the admission rate (p = 0.257) or the mortality rate (p = 0.253). Among the urgent subgroup patients, OPD-referred patients (n = 433), compared with self-referred patients (n = 426), had a significantly higher admission rate (46.0% vs. 20.2%; p < 0.001; OR 3.36), but not mortality rate (2.1% vs. 0.5%; p = 0.064). Regarding the length of ED stay, OPD-referred and self-referred patients had a significant difference only in the "urgent and discharged" subgroup (5.8 vs. 2.3 h; p < 0.001). CONCLUSIONS OPD-referred ED patients might have more severe and complex conditions and need comprehensive care management.

BMC Cardiovasc Disord 2023; 23:388. [PMID: 37542240 PMCID: PMC10403904 DOI: 10.1186/s12872-023-03372-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Accepted: 06/28/2023] [Indexed: 08/06/2023] Open
Abstract
BACKGROUND Fever can occur after acute myocardial infarction (MI). The influence of body temperature (BT) after hospital arrival on patients with acute MI has rarely been investigated. METHODS Patients who were diagnosed with acute MI in the emergency department (ED) of a tertiary teaching hospital between 1 January 2020 and 31 December 2020 were enrolled. Based on the tympanic temperature obtained at the ED triage, patients were categorized into normothermic (35.5°C-37.5°C), hypothermic (< 35.5°C), or hyperthermic (> 37.5°C) groups. The primary outcome was in-hospital cardiac arrest (IHCA), while the secondary outcomes were adverse events. Statistical significance was set at p < 0.05. RESULTS There were 440 enrollees; significant differences were found among the normothermic (n = 369, 83.9%), hypothermic (n = 27, 6.1%), and hyperthermic (n = 44, 10.0%) groups in the triage respiratory rate (median [IQR]) (20.0 [4.0] cycles/min versus 20.0 [4.0] versus 20.0 [7.5], p = 0.009), triage heart rate (88.0 [29.0] beats/min versus 82.0 [28.0] versus 102.5 [30.5], p < 0.001), presence of ST-elevation MI (42.0% versus 66.7% versus 31.8%, p = 0.014), need for cardiac catheterization (87.3% versus 85.2% versus 72.7%, p = 0.034), initial troponin T level (165.9 [565.2] ng/L versus 49.1 [202.0] versus 318.8 [2002.0], p = 0.002), peak troponin T level (343.8 [1405.9] ng/L versus 218.7 [2318.2] versus 832.0 [2640.8], p = 0.003), length of ICU stay (2.0 [3.0] days versus 3.0 [8.0] versus 3.0 [9.5], p = 0.006), length of hospital stay (4.0 [4.5] days versus 6.0 [15.0] versus 10.5 [10.8], p < 0.001), and infection during hospitalization (19.8% versus 29.6% versus 63.6%, p < 0.001) but not in IHCA (7.6% versus 14.8% versus 11.4%, p = 0.323) or any adverse events (50.9% versus 48.1% versus 63.6%, p = 0.258). Multivariable analysis showed no significant association of triage BT with IHCA or any major complication. CONCLUSION Triage BT did not show a significant association with IHCA or adverse events in patients with acute MI. However, triage BT could be associated with different clinical presentations and should warrant further investigation.

Lin IC, Chiu PW, Lin CH. Impact of the Emergency Procedure Zone on Emergency Care. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59050901. [PMID: 37241133 DOI: 10.3390/medicina59050901] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 05/02/2023] [Accepted: 05/03/2023] [Indexed: 05/28/2023]
Abstract
Background: Emergency department (ED) overcrowding is a public health crisis that affects patient care quality. Space management in the ED can affect patient flow dynamics and clinical practice. We proposed a novel design of the "emergency procedure zone" (EPZ). The purpose of the EPZ was to provide an isolated area for clinical practice and procedure teaching, to ensure a secure area with adequate equipment and monitors, and safeguard patient privacy and safety. This study aimed to analyze the impact of the EPZ on procedural practice and patient flow dynamics. Methods: This study was conducted at the ED of a tertiary teaching hospital in Taiwan. Data were collected from 1 March 2019 to 31 August 2020 (pre-EPZ period) and from 1 November 2020 to 30 April 2022 (post-EPZ period). Statistical analyses were performed using IBM SPSS Statistics software. This study focused on the number of procedures and length of stay in the emergency department (LOS-ED). Variables were analyzed using the chi-square test and Mann-Whitney U test. Statistical significance was defined as p < 0.05. Results: There were 137,141 (pre-EPZ period) and 118,386 (post-EPZ period) ED visits recorded during this period. The post-EPZ period showed a significant increase in central venous catheter insertion, chest tube or pigtail placement, arthrocentesis, lumbar puncture, and incision and drainage procedures (p < 0.001). For patients who were directly discharged from the ED, the post-EPZ period also had a higher percentage of ultrasound studies performed in the ED and a shorter LOS-ED for patients who were directly discharged from the ED (p < 0.001). Conclusions: The establishment of an EPZ in the ED has a positive impact on procedural efficiency. The EPZ improved diagnosis and disposition efficiency, shortened the length of stay, and provided benefits such as improved management, patient privacy, and teaching opportunities.

Jiang H. A SWOT analysis of smart governance applications amid the COVID-19 pandemic. INFORMATION POLITY 2022.

Abstract
Smart governance technologies are emergent information and communication technologies (ICT), which amid the COVID-19 pandemic have been widely used to govern COVID’s impacts. However, very few studies have provided insight into the strengths, weaknesses, opportunities, and threats (SWOT) of smart governance technologies under COVID-19. This prevents the widespread usage of smart governance technologies across cities and countries and impedes their usefulness during emergencies. This study combines knowledge of emergency management theory and planning support systems (PSS) to frame the functional usefulness of smart governance technologies in handling practical tasks amid the COVID-19 state of emergency into a task-technology fit model. By employing qualitative content analysis to collect views and insights from the international news-based cases (n= 69), we identify SWOT of smart governance technologies under COVID-19. Results indicate that usefulness of smart governance technologies is reflected in task-handling in the ex-post emergency phases of response (e.g., provide e-health service, tracing and tracking) and recovery (e.g., improve e-government services, enhance collaboration for renewal), whereas few applications focus on tasks in the ex-ante emergency phases of mitigation (e.g., hazard analysis, vulnerability assessment) and preparedness (e.g., planning, training and exercises). Main findings lead to a conclusion that hidden capacities of smart governance technologies can be fully achieved if policy makers and practitioners can focus on the full range of tasks and demands before, amid, or after emergencies and identify collaborative opportunities for technological development.

Abstract
BACKGROUND Aerosols and droplets are the transmission routes of many respiratory infectious diseases. The COVID-19 management guidance recommends against the use of nebulized inhalation therapy directly in the emergency room or in an ambulance to prevent possible viral transmission. The three-dimensional printing method was used to develop an aerosol inhalation treatment mask that can potentially prevent aerosol dispersion. We conducted this utility validation study to understand the practicability of this new nebulizer mask system. RESULTS The fit test confirmed that the filter can efficiently remove small particles. The different locations of the mask had an excellent fit with a high pressure making a proper face seal usability. The full-face mask appeared to optimize filtration with pressure and is an example of materials that perform well for improvised respiratory protection using this design. The filtering effect test confirmed that the contamination of designated locations could be protected when using the mask with filters. As in the clinical safety test, a total of 18 participants (10 [55.6%] females; aged 33.1 ± 0.6 years) were included in the final analysis. There were no significant changes in SPO2, EtCO2, HR, SBP, DBP, and RR at the beginning, 20th, 40th, or 60th minutes of the test (all p >.05). The discomfort of wearing a mask increased slightly after time but remained within the tolerable range. The vision clarity score did not significantly change during the test. The mask also passed the breathability test. CONCLUSION The results of our study showed that this mask performed adequately in the fit test, the filtering test, and the clinical safety test. The application of a full-face mask with antiviral properties, together with the newly designed shape of a respirator that respects the natural curves of a human face, will facilitate the production of personal protective equipment with a highly efficient filtration system. METHODS We conducted three independent tests in this validation study: (1) a fit test to calculate the particle number concentration and its association with potential leakage; (2) a filtering effect test to verify the mask's ability to contain aerosol spread; and (3) a clinical safety test to examine the clinical safety, comfortableness, and visual clarity of the mask.
