Airway management is a common and critical procedure in acute settings, such as the Emergency Department (ED) or Intensive Care Unit (ICU) of hospitals. Many of the traditional physical examination methods have limitations in airway assessment. Point-of-care ultrasound (POCUS) has emerged as a promising tool for airway management due to its familiarity, accessibility, safety, and non-invasive nature. It can assist physicians in identifying relevant anatomy of the upper airway with objective measurements of airway parameters, and it can guide airway interventions with dynamic real-time images. To date, ultrasound has been considered highly accurate for assessment of the difficult airway, confirmation of proper endotracheal intubation, prediction of post-extubation laryngeal edema, and preparation for cricothyrotomy by identifying the cricothyroid membrane. This review aims to provide a comprehensive overview of the key evidence on the use of ultrasound in airway management. Databases including PubMed and Embase were systematically searched. A search strategy using a combination of the term “ultrasound” combined with several search terms, i.e., “probe”, “anatomy”, “difficult airway”, “endotracheal intubation”, “laryngeal edema”, and “cricothyrotomy” was performed. In conclusion, POCUS is a valuable tool with multiple applications ranging from pre- and post-intubation management. Clinicians should consider using POCUS in conjunction with traditional exam techniques to manage the airway more efficiently in the acute setting.

Few studies have investigated the association between dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) performance and the outcomes of out-of-hospital cardiac arrest (OHCA) among communities with different socioeconomic statuses (SES). A retrospective cohort study was conducted using an Utstein-style population OHCA database in Tainan, Taiwan, between January 2014 and December 2015. SES was defined based on real estate prices. The outcome measures included the achievement of return of spontaneous circulation (ROSC) and the performance of DA-CPR. Statistical significance was set at a two-tailed p-value of less than 0.05. A total of 2928 OHCA cases were enrolled in the high SES (n = 1656, 56.6%), middle SES (n = 1025, 35.0%), and low SES (n = 247, 8.4%) groups. The high SES group had a significantly higher prehospital ROSC rate, ever ROSC rate, and sustained ROSC rate and good neurologic outcomes at discharge (all p < 0.005). The low SES group, compared to the high and middle SES groups, had a significantly longer dispatcher recognition time (p = 0.004) and lower early (≤60 s) recognition rate (p = 0.029). The high SES group, but none of the DA-CPR measures, had significant associations with sustained ROSC in the multivariate regression model. The low SES group was associated with a longer time to dispatcher recognition of cardiac arrest and worse outcomes of OHCA. Strategies to promote public awareness of cardiac arrest could be tailored to neighborhood SES.

Background: Supraventricular tachycardia (SVT) is a common arrhythmia requiring prompt intervention in the emergency department (ED). Despite evidence-based guidelines recommending a stepwise approach, significant variability in clinical practice persists, particularly in adenosine dosing strategies. Objective: This study assessed adherence to SVT treatment protocols in the ED, focusing on the efficacy of an initial 6 mg versus 12 mg adenosine dose and the use of alternative pharmacologic agents. Methods: This multi-center, retrospective cohort study analyzed adult patients (≥18 years) diagnosed with stable SVT in urban EDs across North Texas between 1 January 2019, and 16 January 2022. Patients who spontaneously converted to normal sinus rhythm or presented with hemodynamically unstable SVT requiring immediate cardioversion were excluded. The primary outcome was the rate of successful conversion to sinus rhythm. Secondary outcomes included frequency of adenosine administration, deviations from 2020 AHA ACLS guidelines in SVT treatment, and risk factors associated with failure to convert to sinus rhythm following adenosine administration. Results: A total of 439 patients were included in the final analysis. Vagal maneuvers were attempted in 26% of cases, achieving a 31% success rate. Adenosine was used in 83% of pharmacologic interventions, with 57.5% receiving 6 mg and 42.5% receiving 12 mg as the initial dose. The 12 mg dose had a significantly higher conversion rate (54.2% vs. 40.6%, p = 0.03). Regression analysis identified key predictors of treatment success, including comorbidities, and baseline hemodynamics. Documentation inconsistencies, particularly regarding vagal maneuvers, were noted. Conclusions: In our cohort, an initial 12 mg adenosine dose was more effective than 6 mg for SVT conversion in the ED. Recognizing and addressing variations in guideline adherence can play a key role in improving patient care. Further prospective research is warranted to optimize dosing strategies and evaluate the impact of standardized protocols on clinical outcomes.

Objective:To investigate the potential impact of implementing alternatives to opioids (ALTOs) protocol in a community emergency department (ED) in North Texas. We hypothesize that the ALTO protocol is associated with decreased opioid utilization without affecting patient satisfaction to pain control and ED flow. Design:A retrospective, single-center, cohort study. Setting:An urban ED. Participants:Adult patients (age >18 years old) who received pain medications in ED during the study timeframe were included. A total of 34,251 patients were included for final analysis. Intervention:Patients receiving pain medication after the implementation of the ALTO protocol during March to August 2019 and patients during the same period from the prior year were identified as the post-protocol group and preprotocol group, respectively. Main outcome measures:The primary outcome was the change in ED opioid administration. Secondary outcomes included patient satisfaction to pain control, left without being seen (LWOBS), door-to-doctor time, and turnaround time. Results:The total opioid administration rate decreased by 59.6 percent after the implementation of the ALTO protocol. The percentage of patients that LWOBS (p = 0.003) and the average door-to-doctor time (p < 0.001) were significantly decreased in the post-protocol group. There was no significant difference in patient satisfaction to pain control (p = 0.192) and average turnaround time (p = 0.209). Conclusions:Implementation of an ALTO protocol was associated with a significant reduction of opioid administration without a negative impact on patient satisfaction regarding pain control and ED flow.

Quality care in healthcare is a multifaceted concept that encompasses the execution of effective medical treatments and the patient’s overall experience. It involves a multitude of factors, including effectiveness, safety, timeliness, equity, and patient centeredness, which are important in shaping the healthcare landscape. This cross-sectional study used the data from the Health Information National Trends Survey 6 (HINTS 6), which collects data on various aspects of health communication and information-seeking behaviors, to investigate the factors associated with quality care among White and Hispanic populations. All adults who participated in HINTS 6 and visited healthcare service at least once in the past 12 months were included in this study. Multivariable logistic regression was used to determine the association between quality care and delay or discriminated care with the adjustment of all other sociodemographic variables. We analyzed a total of 3611 participants. Poor social determinants of health (SDOHs) (OR 0.61, CI 0.43–0.88, p = 0.008), delayed needed medical care (OR 0.34, CI 0.26–0.43, p < 0.001), and discriminated care (OR 0.29, CI 0.15–0.54, p < 0.001) were all negatively associated with optimal quality care. Negative SDOHs could also be positively associated with delayed care and discriminated care.
