The preventability of trauma-related death: A two-year cohort study in a trauma center in middle Taiwan

Preventability of injury-related morbidity & mortality at four hospitals in Cameroon: A systematic approach to trauma quality improvement

BACKGROUND

Adverse events reviews are a fundamental component of trauma quality improvement (QI) that facilitate the correction of systemic issues in care. Although injury-related mortality in Cameroon is substantial, to our knowledge, opportunities for QI have not been formally assessed. Thus, a formal review of adverse events in Cameroonian trauma patients was implemented as a first step toward identifying targets for systems modification.

METHODS

A QI committee composed of multidisciplinary experts at four hospitals in Cameroon was formed to review adverse events including deaths among trauma patients from 2019 to 2021. Events were discussed at newly established morbidity and mortality conferences and committee meetings to identify contributing factors and overall preventability.

RESULTS

During 50 meetings, 95 adverse events were reviewed, including 58 deaths (61%). Other adverse events were delays in diagnosis/treatment (22%) and surgical site infections (17%). Overall, 34 deaths (59%) were classified as preventable, 21% potentially preventable, and 21% not preventable. Over half (52%) of the 46 preventable or potentially preventable deaths occurred in the emergency department (ED); while brain injury (57%), respiratory failure (41%), and hemorrhage (39%) were the most frequent physiologic factors associated with mortality. Contributory factors identified include lack of a structured approach to patient management, absence of continuous training for personnel, and locally adapted protocols.

CONCLUSIONS

Basic improvements in evaluation and management of life-threatening issues in the ED can significantly reduce the high rate of preventable trauma-related deaths across Cameroon. Formal trauma QI methods can be utilized in low-resource environments to determine mortality root causes and identify intervention targets.

Reliability of the safety threats and adverse events in trauma (STAT) taxonomy using trauma video review

PURPOSE

The STAT (Safety Threats and Adverse Events in Trauma) taxonomy was developed through expert consensus, and groups 65 identified trauma resuscitation adverse events (AEs) into nine distinct categories. It provides a framework for standardized analysis of trauma resuscitations and creates a foundation for targeted quality improvement and patient safety initiatives. This study aims to evaluate the reliability of the STAT taxonomy in identifying AEs during video-recorded trauma resuscitations.

METHODS

High-definition audiovisual data from 30 trauma resuscitations were reviewed. Videos were assessed and scored by four independent reviewers (two trainees and two staff). The STAT taxonomy was used to identify AEs based on binary responses: yes and no. Inter-rater reliability was calculated using Gwet's AC1. The frequencies of AEs were tallied and reported as counts and percentages.

RESULTS

The most common AEs identified in the videos were failure to measure temperature (86.7%) and inadequate personal protective equipment (86.7%), followed by inability to use closed-loop communication (76.7%). The agreement on all AEs between reviewers was 0.94 (95% CI: 0.93-0.95). The Gwet's AC1 agreement across the 9 AE categories was paramedic handover (0.82), airway and breathing (0.99), circulation (0.95), assessment of injuries (0.91), management of injuries (0.96), procedure-related (0.97), patient monitoring and IV access (0.99), disposition (0.98), team communication and dynamics (0.87).

CONCLUSION

The STAT taxonomy demonstrated excellent inter-rater reliability between reviewers and can be used to identify AEs in video-recorded trauma resuscitations. These results provide a foundation for adapting video review to objectively quantify and assess AEs in the trauma bay.

Preventable deaths in hospitalized trauma patients

AIM

To study the preventable trauma deaths of hospitalized patients in the United Arab Emirates and to identify opportunities for improvement.

METHODS

We analyzed the Abu Dhabi Emirate Trauma Registry data of admitted patients who died in the emergency department or in hospital from 2014 to 2019. A panel of experts categorize the deaths into not preventable (NP), potentially preventable (PP), and definitely preventable (DP).

RESULTS

A total of 405 deaths were included, and 82.7% were males. The majority (89.1%) were NP, occurring mainly in the emergency department (40.4%) and the intensive care unit (49.9%). The combined potentially preventable and preventable death rate was 10.9%. The median (Interquartile range) age of the DP was 57.5 (37-76) years, compared with 32 (24-42) and 34 (25-55) years for NP and PP, respectively (p = 0.008). Most of the PP deaths occurred in the intensive care unit (55.6%), while the DP occurred mainly in the ward (50%). Falls accounted for 25% of PP and DP. Deficiencies in airway care, hemorrhage control, and fluid management were identified in 25%, 43.2% and 29.5% of the DP/PP deaths, respectively. Seventy-two percent of the Airway deficiencies occurred in the prehospital, while 34.1% of hemorrhage control deficiencies were in the emergency department. Fluid management deficiencies occurred in the emergency department and the operation theater.

CONCLUSIONS

DP and PP deaths comprised 10.9% of the deaths. Most of the DP occurred in the emergency department and ward. Prehospital Airway and in-hospital hemorrhage and excessive fluid were the main areas for opportunities for improvement.
