Emergency physician-based intensive care unit for critically ill patients visiting emergency department

Assessment of Hospital Medical Emergency Team Operations in a Tertiary Care Center in Turkey

BACKGROUND

Rapid Response Teams, strategically devised to mitigate mortality and morbidity stemming from unforeseen deteriorations and cardiac arrests within healthcare facilities, are ubiquitously implemented on a global scale.

AIM

The aim of the study is to compare emergency physicians (EPs) and non-EPs on management protocols of Hospital Medical Emergency Teams (HoMET).

METHODS

This was a retrospective cross-sectional study. The hospital archive underwent a retrospective scanning process, and patient records were meticulously examined. The assessment encompassed various facets, including demographic characteristics, activation locations, and response and intervention times of HoMET teams, composed of both EPs and other healthcare professionals. Data analysis was conducted using SPSS software version 20.0.

RESULTS

A total of 1056 calls were included, with 52% (n = 549) involving male patients. The average age was 67.15 ± 19.45 years. EPs served as the team leader in 53% of the calls. Cardiac arrest was considered in 93.6% of the cases. The EPs group exhibited a higher average patient age, longer intervention times, and shorter arrival times (P < 0.001, P = 0.027, P < 0.001, respectively). A significant difference was observed in the locations of the calls and the groups of calls considering cardiac arrest (P < 0.001, P < 0.001, respectively).

CONCLUSION

The optimization of intervention teams is imperative given the persistently high incidence and mortality rates associated with in-hospital cardiac arrests. Leveraging the expertise of EPs in the management of arrests and critical patients can potentially enhance the effectiveness of these teams. Nonetheless, further research is warranted to comprehensively explore and validate this aspect.

Case volume and specialization in critically ill emergency patients: a nationwide cohort study in Japanese ICUs

BACKGROUND

Previous studies have explored the association between the number of cases and patient outcomes for critical illnesses such as sepsis and trauma, as well as various surgeries, with the expectation that a higher number of cases would have a more favorable effect on patient outcomes. The aim of this study was to elucidate the association among intensive care unit (ICU) case volume, specialization, and patient outcomes in critically ill emergency patients and to determine how ICU case volumes and specializations impact the outcomes of these patients in Japanese ICUs.

METHODS

Utilizing data from the Japanese Intensive Care PAtient Database (JIPAD) from April 2015 to March 2021, this retrospective cohort study was conducted in 80 ICUs across Japan and included 72,214 emergency patients aged ≥ 16 years. The primary outcome measure was in-hospital mortality, and the secondary outcomes encompassed ICU mortality, 28-day mortality, ventilator-free days, and the lengths of ICU and hospital stays. Bayesian hierarchical generalized linear mixed models were used to adjust for patient- and ICU-level variables.

RESULTS

This study revealed a significant association between a higher ICU case volume and decreased in-hospital mortality. In particular, ICUs with a higher percentage (> 75%) of emergency patients showed more pronounced effects, with the odds ratios for in-hospital mortality in the higher case volume quartiles (Q2, Q3, and Q4) being 0.92 (95% credible interval [CI]: 0.88-0.96), 0.70 (95% CI: 0.67-0.73), and 0.78 (95% CI: 0.73-0.83), respectively, compared with the lowest quartile (Q1). Similar trends were observed for various secondary outcomes.

CONCLUSIONS

Higher ICU case volumes were significantly associated with lower in-hospital mortality rates in Japanese ICUs predominantly treating critically ill emergency patients. These findings emphasize the importance of ICU specialization and highlight the potential benefits of centralized care for critically ill emergency patients. These findings are potential insights for improving health care policy in Japan and may be valuable in emergency care settings in other countries with similar healthcare systems, after careful consideration of contextual differences.

The management of the poisoned patient using a novel emergency department-based resuscitation and critical care unit (ResCCU)

OBJECTIVES

The Resuscitation & Critical Care Unit (ResCCU) is a novel ED-based ICU designed to provide early critical care services. This study sought to identify characteristics of poisoned patients treated in the ResCCU.

METHODS

We conducted a retrospective, single-center case study of poisoned patients over the age of 18 years old over a 16-month period. Patient demographics, drug concentrations, and severity of illness scores were extracted from electronic medical records. Patients were divided into two groups, those who required short term ICU level care (< 24 h) and prolonged ICU care (> 24 h).

RESULTS

A total of 58 ED visits with a tox-related illness were analyzed. There were 24 women (41%) and 34 men (59%). There were 42 patients (72%) who required short term ICU level care and 16 patients (28%) who required prolonged ICU care. In the short-term ICU group, 13 patients (31%) were discharged home directly from the ResCCU, 29 patients (69%) were sent to the inpatient floor, and 1 of the admitted floor patients expired. There were no patients admitted to the floor that required a step-up to the inpatient ICU. 56 patients (97%) were alive at post-admit day 7 and 28, and only 8 (14%) were re-admitted within 30 days.

CONCLUSIONS

Patients who were treated in the ED-based ICU for toxicology-related illnesses were frequently able to be either discharged home or admitted to a regular floor after their initial stabilization and treatment, and none that were sent to the floor required an ICU step-up.

Identification of Serious Adverse Events in Patients with Traumatic Brain Injuries, from Prehospital Care to Intensive-Care Unit, Using Early Warning Scores

Traumatic brain injuries are complex situations in which the emergency medical services must quickly determine the risk of deterioration using minimal diagnostic methods. The aim of this study is to analyze whether the use of early warning scores can help with decision-making in these dynamic situations by determining the patients who need the intensive care unit. A prospective, multicentric cohort study without intervention was carried out on traumatic brain injury patients aged over 18 given advanced life support and taken to the hospital. Our study included a total of 209 cases. The total number of intensive-care unit admissions was 50 cases (23.9%). Of the scores analyzed, the National Early Warning Score2 was the best result presented with an area under the curve of 0.888 (0.81–0.94; p < 0.001) and an odds ratio of 25.4 (95% confidence interval (CI):11.2–57.5). The use of early warning scores (and specifically National Early Warning Score2) can help the emergency medical services to differentiate traumatic brain injury patients with a high risk of deterioration. The emergency medical services should use the early warning scores routinely in all cases for the early detection of high-risk situations.
