The ticking clock: does actively making an enhanced care team aware of the passage of time improve pre-hospital scene time following traumatic incidents?

Temporalities of emergency: the experiences of Indigenous women with traumatic brain injury from violence waiting for healthcare and service support in Australia

Globally, traumatic brain injury (TBI) has been recognised as a serious health issue not only because of the immediate impacts at the time the injury occurs but even more so due to the longstanding impacts. Even though TBI is a globally recognised condition, the research is disproportionately focused on its incidence in, and immediate and long-term effects on men. A growing body of research suggests that generally, women who experience family violence are at high risk of TBI and suffer its impacts in ways that reflect gendered differences in the patterns and frequency of violence. In Australia, the social and physical costs of TBI are multiplied for Indigenous women, whose experience of disability and access to healthcare lies at the intersection of gender and race in the historical context of settler colonialism. The present study addresses the need for research into the sociodemographic inequalities that affect access to culturally appropriate hospital care, timely response systems, and flexible, safe and engaged social services. This paper draws on data from interviews and focus groups with Indigenous women, hospital staff and community-based service providers and suggests potential pathways for further research in settler-colonial settings elsewhere in the world.

The effect of a clock's presence on trauma resuscitation times in a Dutch level-1 trauma center: a pre-post cohort analysis

PURPOSE

Interventions performed within the first hour after trauma increase survival rates. Literature showed that measuring times can optimize the trauma resuscitation process as time awareness potentially reduces acute care time. This study examined the effect of a digital clock placement on trauma resuscitation times in an academic level-1 trauma center.

METHODS

A prospective observational pre-post cohort analysis was conducted for six months before and after implementing a visible clock in the trauma resuscitation room, indicating the time passed since starting the in-hospital resuscitation process. Trauma patients (age ≥ 16) presented during weekdays between 9.00 AM and 9.00 PM were included. Time until diagnostics (X-Ray, FAST, or CT scan), time until therapeutic intervention, and total resuscitation time were measured manually with a stopwatch by a researcher in the trauma resuscitation room. Patient characteristics and information regarding trauma- and injury type were collected. Times before and after clock implementation were compared.

RESULTS

In total, 100 patients were included, 50 patients in each cohort. The median total resuscitation time (including CT scan) was 40.3 min (IQR 23.3) in the cohort without a clock compared to 44.3 (IQR 26.1) minutes in the cohort with a clock. The mean time until the first diagnostic and until the CT scan was 8.3 min (SD 3.1) and 25.5 min (SD 7.1) without a clock compared to 8.6 min (SD 6.5) and 26.6 min (SD 11.5) with a clock. Severely injured patients (Injury Severity Score (ISS) ≥ 16) showed a median resuscitation time in the cohort without a clock (n = 9) of 54.6 min (IQR 50.5) compared to 46.0 min (IQR 21.6) in the cohort with a clock (n = 8).

CONCLUSION

This study found no significant reduction in trauma resuscitation time after clock placement. Nonetheless, the data represent a heterogeneous population, not excluding specific patient categories for whom literature has shown that a short time is essential, such as severely injured patients, might benefit from the presence of a trauma clock. Future research is recommended into resuscitation times of specific patient categories and practices to investigate time awareness.

Disparities in Emergency Medical Services Time Intervals for Patients with Suspected Acute Coronary Syndrome: Findings from the North Carolina Prehospital Medical Information System

Background

Timely emergency medical services (EMS) response, management, and transport of patients with suspected acute coronary syndrome (ACS) significantly reduce delays to emergency treatment and improve outcomes. We evaluated EMS response, scene, and transport times and adherence to proposed time benchmarks for patients with suspected ACS in North Carolina from 2011 to 2017.

Methods and Results

We conducted a population‐based, retrospective study with the North Carolina Prehospital Medical Information System, a statewide electronic database of all EMS patient care reports. We analyzed 2011 to 2017 data on patient demographics, incident characteristics, EMS care, and county population density for EMS‐suspected patients with ACS, defined as a complaint of chest pain or suspected cardiac event and documentation of myocardial ischemia on prehospital ECG or prehospital activation of the cardiac care team. Descriptive statistics for each EMS time interval were computed. Multivariable logistic regression was used to quantify relationships between meeting response and scene time benchmarks (11 and 15 minutes, respectively) and prespecified covariates. Among 4667 patients meeting eligibility criteria, median response time (8 minutes) was shorter than median scene (16 minutes) and transport (17 minutes) time. While scene times were comparable by population density, patients in rural (versus urban) counties experienced longer response and transport times. Overall, 62% of EMS encounters met the 11‐minute response time benchmark and 49% met the 15‐minute scene time benchmark. In adjusted regression analyses, EMS encounters of older and female patients and obtaining a 12‐lead ECG and venous access were independently associated with lower adherence to the scene time benchmark.

Conclusions

Our statewide study identified urban–rural differences in response and transport times for suspected ACS as well as patient demographic and EMS care characteristics related to lower adherence to scene time benchmark. Strategies to reduce EMS scene times among patients with ACS need to be developed and evaluated.

Trauma Bay Time Clocks: Influence on Emergency Department Length of Stay

BACKGROUND

To monitor the time elapsed since patient arrival in the emergency department, Trauma Services at the study institution installed a large digital stopwatch timer placed at the head of each trauma bay on June 5, 2017. This quality improvement endeavor became an essential component of performance evaluation.

OBJECTIVE

The purpose of the study is to measure the impact of trauma bay time clocks on emergency department length of stay.

METHODS

This is a retrospective before-and-after study of trauma activation patients between June 2015 and May 2019. Two 24-month intervals were compared before and after installation of time clocks.

RESULTS

In full activation patients, outcomes of emergency department length of stay ≤50 min (39.2% vs. 61.7%, p < .001) and time to transfer to intensive care unit ≤56 min (45.3% vs. 55.1%, p = .002) were significantly favorable in the postimplementation phase. Time to first computed tomography scan and time to first operating room from arrival to the emergency department were comparable between both phases. For limited activation patients, positive changes were noted in emergency department length of stay ≤87 min (41.4% vs. 60.6%, p < .001), time to first computed tomography scan ≤32 min (47.7% vs. 53.0%, p = .015), and time to transfer to intensive care unit ≤74 min (50.2% vs. 57.2%, p = .008). Time to first operating room remained comparable between two periods.

CONCLUSIONS

The study institution improved their provision of immediate care by using time clocks in trauma bays. This is a simple and cost-effective intervention and may benefit similar institutions.
