Cabilan CJ, Eley R, Staib A, Rowney B, Kay P. Effect of computed tomography scanner location on time-to-computed tomography in the emergency department: A before and after study. Emerg Med Australas 2021; 34:370-375. [PMID: 34786840 DOI: 10.1111/1742-6723.13899] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2021] [Revised: 10/12/2021] [Accepted: 10/20/2021] [Indexed: 12/01/2022]
Abstract
OBJECTIVES To compare time metrics associated with a temporary disruption to ED computed tomography (CT) scanner location from adjacent to the ED with direct access from resuscitation rooms, to a location remote to the ED. METHODS A retrospective before and after study was conducted in a public metropolitan ED with over 66 000 presentations annually. Time-to-CT metrics, operational time metrics and ED length of stay were extracted and analysed from presentations between October 2020 and January 2021. RESULTS There were 3031 CT scans during the study period. Overall, the disruption was associated with a significant 27-36 min delay (P < 0.01) in time-to-CT start; these delays were also observed in a subset of trauma patients. In a subset of presumed stroke patients, time-to-brain perfusion was significantly delayed by up to 10 min (P < 0.01). There was a 14% (P < 0.01) greater demand for operational services and a time imposition of up to 8 min (P < 0.01) to transport patients to or from CT scanning when the CT scanner was located away from the ED. ED length of stay was consistent at all time points. CONCLUSION Although rapid, proximate access to CT scanning is often considered desirable in terms of the management of trauma and other time-critical emergencies, the wider time and resource implications demonstrated in this study suggest a potential broader benefit to co-located CT scanning in ED. Our experience could be considered in future re-design of EDs.

Abstract
To support safety and efficient care, effective integration of technology into the timepressured, high-risk healthcare environments is critical. This systematic literature review aimed to highlight the impact of technology on the physical environment as well as the facilitators for and barriers to technology integration into complex healthcare settings, including operating rooms and trauma rooms. PsycINFO, Web of Science, and PubMed databases were utilized, along with a hand search. PRISMA and MMAT guidelines were used for reporting and quality appraisal. Out of 1,001 articles, 20 were eligible. Identified categories included hybrid and integrated environments, technological ambiance, and information technologies. Technology integration has implications for direct patient care, efficiency, throughput, patient safety, teamwork, communication, and the perception of care. The facilitators for and barriers to technology integration included layout design, equipment positioning, and decluttering. The physical environment can improve the impact of technology on factors such as patient safety and efficiency.

Time to first CT scan after admission in moderate-to-severe traumatic brain injury and its association with mortality. Neurosurg Rev 2020; 44:2697-2706. [PMID: 33340052 PMCID: PMC8490239 DOI: 10.1007/s10143-020-01456-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Revised: 11/18/2020] [Accepted: 12/07/2020] [Indexed: 11/29/2022]
Abstract
Fast acquisition of a first computed tomography (CT) scan after traumatic brain injury (TBI) is recommended. This study is aimed at investigating whether the length of the period preceding initial CT scan influences mortality in patients with leading TBI. A retrospective cohort analysis of patients registered in the TraumaRegister DGU® was conducted including adult patients with TBI, defined as Abbreviated Injury ScaleHead ≥ 3 and GCS ≤ 13 who had been treated in level 1 or 2 trauma centers from 2007-2016. Patients were grouped according to time intervals either from trauma or from admission to CT. A total of 6904 patients met the inclusion criteria. Mean time period from trauma to hospital admission was 68.8 min. From admission to first CT, a mean of 19.0 min elapsed. Trauma severity was higher in groups with a longer duration from trauma to CT as represented by a mean (± standard deviation) Injury Severity Score (ISS) of 19.8 ± 9.0, 20.7 ± 9.3, and 21.4 ± 7.5 and similar distribution of mortality of 24.9%, 29.9%, and 36.3% in the ≤ 60-min, 61-120-min, and ≥ 121-min groups, respectively. An adjusted multivariable logistic regression model showed a significant influence of the level of the trauma center (p = 0.037) but not for interval from admission to CT (p = 0.528). TBI patients with a longer time span from trauma to first CT were more severely injured and demonstrated a worse prognosis, but received a CT scan faster when duration from admission is observed. The duration until the CT scan was obtained showed no significant impact on the mortality.

Abstract
OBJECTIVE The timely treatment of severe traumatic brain injury (TBI) is essential for limiting the effects of damage; however, there is no consensus regarding an effective method for early intervention. In August 2011, our hospital launched a novel trauma workflow using the hybrid emergency room (ER), consisting of an interventional radiology-computed tomography (CT) unit installed in the trauma resuscitation room to facilitate early interventions. The aim of this study was to evaluate effects of the hybrid ER system on functional outcomes in patients with severe TBI. METHODS We conducted a retrospective historical control study of patients with severe TBI (Glasgow Coma Scale score ≤8) who received conventional treatment (August 2007-July 2011) or treatment in the hybrid ER (August 2011-July 2015). The primary end point was unfavorable outcome at 6 months after injury (death, vegetative state, or lower severe disability) as evaluated by the Glasgow Outcome Scale-Extended. Secondary end points included time from arrival to the start of CT examination and emergency intracranial operation. Potential confounders were adjusted with multivariable logistic regressions. RESULTS Among 158 included patients, 88 were in the conventional group and 70 were in the hybrid ER group. After model adjustment, the hybrid ER group was significantly associated with a reduction in unfavorable outcomes. Times to CT examination and intracranial operation were significantly shorter in the hybrid ER group than that in the conventional group. CONCLUSIONS The hybrid ER system is useful for realizing immediate CT examination and emergency surgery and improving functional outcomes in patients with severe TBI.

Lang P, Kulla M, Kerwagen F, Lefering R, Friemert B, Palm HG. The role of whole-body computed tomography in the diagnosis of thoracic injuries in severely injured patients - a retrospective multi-centre study based on the trauma registry of the German trauma society (TraumaRegister DGU ®). Scand J Trauma Resusc Emerg Med 2017; 25:82. [PMID: 28810921 PMCID: PMC5558663 DOI: 10.1186/s13049-017-0427-4] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2017] [Accepted: 08/07/2017] [Indexed: 12/14/2022] Open
Abstract
Background Thoracic injuries are a leading cause of death in polytrauma patients. Early diagnosis and treatment are of paramount importance. Whole-body computed tomography (WBCT) has largely replaced traditional imaging techniques such as conventional radiographs and focused computed tomography (CT) as diagnostic tools in severely injured patients. It is still unclear whether WBCT has led to higher rates of diagnosis of thoracic injuries and thus to a change in outcomes. Methods In a retrospective study based on the trauma registry of the German Trauma Society (TraumaRegister DGU®), we analysed data from 16,545 patients who underwent treatment in 59 hospitals between 2002 and 2012 (ISS ≥ 9). The 3 years preceding and the 3 years following the introduction of WBCT as a standard imaging modality for the investigation of severely injured patients were assessed for every hospital. Accordingly, patients were assigned to either the pre-WBCT or the WBCT group. We compared the numbers of thoracic injuries and the outcomes of patients before and after the routine use of WBCT. Results A total of 13,564 patients (pre-WBCT: n = 5005, WBCT: n = 8559) were included. Relevant thoracic injuries were detected in 47.8%. There were no major differences between the patient groups in injury severity (pre-WBCT: median ISS 21; WBCT: median ISS 22), injury patterns and demographics. After the introduction of WBCT, only minor changes were observed regarding the rates of most thoracic injuries. Clinically relevant injuries were pulmonary contusions (pre-WBCT: 18.5%; WBCT: 28.7%), injuries to the lung parenchyma (pre-WBCT: 12.6%; WBCT: 5.9%), multiple rib fractures (pre-WBCT: 10.6%; WBCT: 21.6%), and pneumothoraces (pre-WBCT: 17.3%; WBCT: 21.6%). The length of stay in the intensive care unit (pre-WBCT: 10.8 days; WBCT: 9.7 days) and in hospital (pre-WBCT: 26.2 days; WBCT: 23.3 days) decreased. There was no difference in overall mortality (pre-WBCT: 15.5%; WBCT: 15.6%). Conclusions The routine use of WBCT in the trauma room setting has led to changes in patient management that are not reflected in the rates of diagnosis of severe thoracic injuries (e.g. tension pneumothoraces, cardiac injuries, arterial injuries). By contrast, there was a relevant increase in the rates of diagnosis of minor thoracic injuries, which, however, did not result in an improvement in survival prognosis.
