Emergency Care and Medicine

Background/Objectives: Emergency department short-stay units (ED SSUs) manage patients requiring short-term observation and treatment. For a small number of patients, a longer hospital admission is required. Care for these patients is provided by an inpatient team and the responsibility for managing acute clinical deterioration falls to a rapid response team, activated by an emergency call. While emergency calls have primarily been a feature of the inpatient setting, admitted patients are increasingly boarding within ED SSUs and the occurrence and impact of emergency calls in this setting remains largely unreported. This study aimed to determine the incidence and characteristics of emergency calls within an ED SSU, describing patient demographics, clinical triggers, and outcomes. Methods: This retrospective cohort study utilised the Tasmanian Emergency Care Outcomes Registry (TECOR) to analyse emergency calls in the ED SSU of a tertiary emergency department between 1 February 2024 and 28 February 2025. Inclusion criteria were defined as adult patients (≥14 years) admitted to an inpatient service who had emergency calls whilst in the ED SSU. Descriptive statistics were used to characterise this cohort. Results: Of 83,238 ED presentations, 11,775 adult patients were transferred to the ED SSU. 1464 (12.4%) of these patients were subsequently admitted under an inpatient service but remained boarding in the ED SSU, with 54 emergency calls occurring in 38 unique patients (2.6%). The median age was 81.5 years (IQR 65–86), older than both the main ED cohort with a median age of 71 years, and median ages of 65 to 69.5 years reported in ward-based cohorts. Most calls were medical emergency team (MET) activations (52, 96.30%) with only 2 (3.7%) code blues. The most common triggers were hypotension (20, 37.04%), reduced level of consciousness (7, 12.96%) and serious concern (7, 12.96%). Delays occurred in 18.52% of calls (mean 82 min). The median ED SSU length of stay for patients having an emergency call was 40.15 h, substantially exceeding the intended ED SSU admission criteria threshold of 24 h. Goals of care remained incomplete in 33.33% of calls, even after emergency team review. Conclusions: ED SSU emergency calls are infrequent but clinically significant, involving an elderly, vulnerable population with late sign triggers and prolonged boarding. These findings highlight fundamental mismatches between patient acuity and ED SSU environment capabilities, emphasising the need for improved monitoring, more selective admission criteria, and enhanced systems for recognising deterioration for patients boarding in ED SSUs.

Background: Not all ambulance missions result in patient transport, often referred to as non-conveyance. However, in some cases, patients discharged at the scene may require further examination and treatment. Patient sex, age, and psychiatric disease seem to be factors associated with non-conveyance. This study aimed to identify and characterise patients not transported following an urgent ambulance mission, and to examine subsequent hospital admission and mortality rates. In addition, we wanted to examine their reasons for calling the Emergency Medical Communication Centre (EMCC). Methods: This retrospective study was conducted for the emergency medical system of Norway’s second-largest city. Data, including information from non-conveyed patients involved in acute or urgent ambulance missions over 1 year, were obtained from the EMCC. The frequency of non-conveyance, patient demographics, and incidence of hospital admissions within 72 h were analysed. Furthermore, the 30-day mortality, predictive factors, and reasons for contacting the EMCC were determined. Results: Out of a total of 22,183 ambulance missions, 7.3% of patients were not conveyed, of whom 5.8% were admitted to hospital within 72 h. The 30-day mortality rate among all non-conveyed patients was 2.4%, whereas 2.1% of hospitalised patients died within 30 days. Psychiatric conditions were frequently observed in both groups. The mortality rate increased significantly with age but was not associated with the number of ambulance requests. Furthermore, 30-day mortality was not significantly associated with sex, time of day, day of the week, or rurality. Conclusions: Our data suggests that there is no difference between the short-term outcomes of non-conveyed and conveyed patients; both groups are equally likely to come to harm. Therefore, the factors influencing non-transportation decisions warrant further investigation. Subsequent events following patient discharge should be routinely collected by ambulance services and monitored for learning and to improve the quality of patient care.

Background/Objectives: Rapid sequence intubation (RSI) involves nearly simultaneous administration of a rapid-acting induction agent and a neuromuscular blocking agent (NMBA) to facilitate ideal intubation conditions. The NMBAs most commonly used for RSI are succinylcholine and rocuronium, which cause paralysis for 5–15 min and 45–70 min, respectively. Awareness with paralysis can occur in patients who are given longer-acting NMBAs with delayed initiation of post-intubation sedation or insufficient sedation depth. The previous literature has associated the use of rocuronium with a significantly longer time to sedation and analgesia. However, a recent study found no difference. The purpose of this study was to assess the association between paralytic agent choice and time to initiation of analgesia and/or sedation after RSI in the emergency department (ED) of a large tertiary care hospital. Methods: This study was an institutional review board (IRB)-approved, single-center, retrospective cohort evaluation of adult patients (≥18 years of age) who received succinylcholine or rocuronium following administration of an induction agent in the ED for RSI during the study time period. The primary outcome was time to initiation of post-intubation analgesia and/or sedation. Continuous data were analyzed by using Mann–Whitney U or Student’s t-test, and categorical data were analyzed using the Chi Square test or Fisher’s Exact test. Results: A total of 400 patients were included in this study. The median time to sedation with succinylcholine was 9 min compared to 14 min with rocuronium (p < 0.01). No significant differences were identified in the baseline characteristics or secondary outcomes related to induction agent choice or ED length of stay. Conclusions: The results of this study further support that the use of rocuronium for RSI is associated with a significantly longer time to sedation and/or analgesia, making emergency medicine provider awareness essential for minimizing the risks associated with inadequate post-intubation sedation.
