Left behind: Exploring the concerns of emergency department staff when personnel are utilised for inter-hospital transfer

BACKGROUND

Inter-Hospital Transfer (IHT) may require an escort from the referring hospital, either a Registered Nurse (RN), physician or both, leading to a sudden drop in staffing levels within the referring department potentially increasing risk to patients and staff.

AIMS

To explore the perspectives of RNs and physicians of differing experience levels when left behind due to an escorted IHT, and the decision-making protocols for IHT.

METHOD

A qualitative exploratory approach of 5 RNs and 4 physicians selected using purposeful sampling. Data were collected through semi-structured interviews and thematically analysed.

FINDINGS

Five themes were identified: the impact of being left behind; the burden of transfer; missed care; a triangulation of competing needs upon the decision-making process; and the effect of inter-hospital transfers on staff with different experience levels.

CONCLUSION

IHT is described differently by less experienced RNs compared to their more experienced counterparts especially concerning safety and risk. Physicians described the department as vulnerable with ad-hoc decision-making protocols surrounding IHT the norm.

A scoping review of worldwide studies evaluating the effects of prehospital time on trauma outcomes

BACKGROUND

Annually, over 1 billion people sustain traumatic injuries, resulting in over 900,000 deaths in Africa and 6 million deaths globally. Timely response, intervention, and transportation in the prehospital setting reduce morbidity and mortality of trauma victims. Our objective was to describe the existing literature evaluating trauma morbidity and mortality outcomes as a function of prehospital care time to identify gaps in literature and inform future investigation.

MAIN BODY

We performed a scoping review of published literature in MEDLINE. Results were limited to English language publications from 2009 to 2020. Included articles reported trauma outcomes and prehospital time. We excluded case reports, reviews, systematic reviews, meta-analyses, comments, editorials, letters, and conference proceedings. In total, 808 articles were identified for title and abstract review. Of those, 96 articles met all inclusion criteria and were fully reviewed. Higher quality studies used data derived from trauma registries. There was a paucity of literature from studies in low- and middle-income countries (LMIC), with only 3 (3%) of articles explicitly including African populations. Mortality was an outcome measure in 93% of articles, predominantly defined as "in-hospital mortality" as opposed to mortality within a specified time frame. Prehospital time was most commonly assessed as crude time from EMS dispatch to arrival at a tertiary trauma center. Few studies evaluated physiologic morbidity outcomes such as multi-organ failure.

CONCLUSION

The existing literature disproportionately represents high-income settings and most commonly assessed in-hospital mortality as a function of crude prehospital time. Future studies should focus on how specific prehospital intervals impact morbidity outcomes (e.g., organ failure) and mortality at earlier time points (e.g., 3 or 7 days) to better reflect the effect of early prehospital resuscitation and transport. Trauma registries may be a tool to facilitate such research and may promote higher quality investigations in Africa and LMICs.

Decompressive craniotomy

An unconscious patient with an extra-dural haematoma may not survive transfer to a neurosurgical centre for definitive care. This article describes a simple approach to a decompressive craniotomy which may be life-saving in these patients when a neurosurgeon is not available.

Development of performance indicators for systems of urgent and emergency care in the Republic of Ireland: Systematic review and consensus development exercise

Objectives: To develop a set of performance indicators to monitor the performance of emergency and urgent care systems in the Republic of Ireland. Design: This study comprised of an update of a previously performed systematic review and a formal consensus development exercise. Results: Initial literature searches yielded 2339 article titles.  After further searches, sixty items were identified for full-text review. Following this review, fifty-seven were excluded. Three articles were identified for inclusion in the systematic review. These papers produced 42 unique indicators for consideration during the consensus development exercise. In total, 17 indicators had a median of greater than 7 following the meeting and met our pre-specified criterion for acceptable consensus. Discussion: Using this systematic review and nominal group consensus development exercise, we have identified a set of 17 indicators, which a consensus of different experts regard as potentially good measures of the performance of urgent and emergency care systems in Ireland.

Development of performance indicators for systems of urgent and emergency care in the Republic of Ireland: Systematic review and consensus development exercise

Objectives: To develop a set of performance indicators to monitor the performance of emergency and urgent care systems in the Republic of Ireland.

Design: This study comprised of an update of a previously performed systematic review and a formal consensus development exercise. The literature search was conducted in PubMed and covered the period 2008 to 2014. The results of the review were used to inform a consensus group of 17 national experts on urgent and emergency care in Ireland. The consensus development exercise comprised an online survey followed by a face-to-face nominal group technique meeting. During this meeting participants had the opportunity to revise their preferences for different indicators after listening to the views of other group members. A final online survey was then used to confirm the preferences of participants.

Results: Initial literature searches yielded 2339 article titles.  After further searches, sixty items were identified for full-text review. Following this review, fifty-seven were excluded. Three articles were identified for inclusion in the systematic review. These papers produced 42 unique indicators for consideration during the consensus development exercise. In total, 17 indicators had a median of greater than 7 following the meeting and met our pre-specified criterion for acceptable consensus.

Discussion: Using this systematic review and nominal group consensus development exercise, we have identified a set of 17 indicators, which a consensus of different experts regard as potentially good measures of the performance of urgent and emergency care systems in Ireland. Pragmatic implications are discussed with reference to three subsequently performed original studies which used some of the indicators

Impact of the introduction of an integrated adult retrieval service on major trauma outcomes

OBJECTIVES

The primary aim of this study was to examine the impact of the introduction of an integrated adult critical care patient retrieval system in Victoria, Australia, on early clinical outcomes for major trauma patients who undergo interhospital transfer. The secondary aims were to examine the impact on quality and process measures for interhospital transfers in this population, and on longer-term patient-reported outcomes.

METHODS

This is a cohort study using data contained in the Victorian State Trauma Registry (VSTR) for major trauma patients >18 years of age between 2009 and 2013 who had undergone interhospital transfer. For eligible patients, data items were extracted from the VSTR for analysis: demographics, injury details, hospital details, transfer details, Adult Retrieval Victoria (ARV) coordination indicator and transfer indicator, key clinical observations and outcomes.

RESULTS

There were 3009 major trauma interhospital transfers in the state with a transfer time less than 24 h. ARV was contacted for 1174 (39.0%) transfers. ARV-coordinated metropolitan transfers demonstrated lower adjusted odds of inhospital mortality compared with metropolitan transfers occurring without ARV coordination (OR 0.39, 0.15 to 0.97). Adjusting for destination hospital type demonstrates that this impact was principally due to ARV facilitation of a Major Trauma Service as the destination for transferred patients (OR 0.41, 0.16 to 1.02). The median time spent at the referral hospital was lower for ARV-coordinated transfers (5.4 h (3.8 to 7.5) vs 6.1 (4.2 to 9.2), p<0.0001).

CONCLUSIONS

In a mature trauma system, an effective retrieval service can further reduce mortality and improve long-term outcomes.

Restructuring an evolving Irish trauma system: What can we learn from Europe and Australia?

AIM

Major trauma is a leading cause of mortality and disability. Internationally, major trauma centres and comprehensive trauma networks are associated with improved outcomes. This study aimed to examine selected international trauma systems in Europe and Australia to identify common themes that may aid reconfiguration of the Irish trauma service.

METHODS

An electronic search strategy was utilised using Medline, and a search of the grey literature using Google and Google Scholar. Search terms included "trauma systems", "trauma care", "major trauma centre" and "trauma network". Relevant articles were reviewed and data summarised in a narrative format.

RESULTS

Republic of Ireland currently lacks designated major trauma centres and surrounding trauma networks. Lessons from international models and data from the on-going national trauma audit may guide reconfiguration. Well-functioning trauma systems internationally bear striking similarities, and involve a hub and spoke model. This model has a central major trauma centre, surrounded by a co-ordinated trauma network with trauma units. Concentration of major trauma into high volume centres is key, but these centres must be adequately resourced to deliver a high quality service. Investment in and co-ordination of prehospital care is essential to overcome geographical impediments to centralising trauma care. Funding of rehabilitation infrastructure and resources is also an integral part of a well-functioning trauma system. Trauma outcome data is key to informing trauma system design, with dissemination of this data and public engagement critical for change.

CONCLUSION

International models of trauma care provide valuable lessons for countries currently in process of reconfiguring trauma services.

Triaging the right patient to the right place in the shortest time

Trauma systems have been successful in saving lives and preventing disability. Making sure that the right patient gets the right treatment in the shortest possible time is integral to this success. Most trauma systems have not fully developed trauma triage to optimize outcomes. For trauma triage to be effective, there must be a well-developed pre-hospital system with an efficient dispatch system and adequately resourced ambulance system. Hospitals must have clear designations of the level of service provided and agreed protocols for reception of patients. The response within the hospital must be targeted to ensure the sickest patients get an immediate response. To enable the most appropriate response to trauma patients across the system, a well-developed monitoring programme must be in place to ensure constant refinement of the clinical response. This article gives a brief overview of the current approach to triaging trauma from time of dispatch to definitive treatment.

Mortality of interhospital transfers originating from an emergency department in Perth, Western Australia

BACKGROUND

Interhospital transfer (IHT) is an integral part of emergency practice and required to access specialist care.

AIM

To identify factors that predict in-hospital mortality for IHT originating from an Emergency Department (ED).

METHOD

A retrospective cohort study utilising linked health data from the ED Information System database, Death Register and the Hospital Morbidity Data examined all IHTs originating from a public hospital ED and transferred to a tertiary hospital ED (ED-ED IHT), January 1st 2002-December 31st 2006.

RESULTS

There were 27,776 ED-ED IHTs. In-hospital mortality was 2.1% (95% CI 1.9-2.3%). Age, male sex, clinical deterioration by one or ≥2 levels on the Australasian Triage Scale (ATS) and circulatory or respiratory disease increased risk of mortality. Clinical improvement by one level on the ATS, injury or poisoning, digestive disease, transfer from 2004 to 2006 and exposure to access block reduced risk of mortality. Other than year of transfer, injury or poisoning, digestive and respiratory disease, these factors were also predictive of mortality within 1-day of transfer.

CONCLUSION

Multiple factors influence mortality following IHT from an ED. Awareness of these factors helps to optimise risk reduction. The limited infrastructure and resourcing available in non-tertiary hospitals are important considerations.

Patients Referred to a Norwegian Trauma Centre: effect of transfer distance on injury patterns, use of resources and outcomes

BACKGROUND

Triage and interhospital transfer are central to trauma systems. Few studies have addressed transferred trauma patients. This study investigated transfers of variable distances to OUH (Oslo University Hospital, Ullevål), one of the largest trauma centres in Europe.

METHODS

Patients included in the OUH trauma registry from 2001 to 2008 were included in the study. Demographic, injury, management and outcome data were abstracted. Patients were grouped according to transfer distance: ≤20 km, 21-100 km and > 100 km.

RESULTS

Of the 7.353 included patients, 5.803 were admitted directly, and 1.550 were transferred. The number of transfers per year increased, and there was no reduction in injury severity during the study period. Seventy-six per cent of the transferred patients were severely injured. With greater transfer distances, injury severity increased, and there were larger proportions of traffic injuries, polytrauma and hypotensive patients. With shorter distances, patients were older, and head injuries and injuries after falls were more common. The shorter transfers less often activated the trauma team: ≤20 km -34%; 21-100 km -51%; > 100 km -61%, compared to 92% of all directly admitted patients. The mortality for all transferred patients was 11%, but was unequally distributed according to transfer distance.

CONCLUSION

This study shows heterogeneous characteristics and high injury severity among interhospital transfers. The rate of trauma team assessment was low and should be further examined. The mortality differences should be interpreted with caution as patients were in different phases of management. The descriptive characteristics outlined may be employed in the development of triage protocols and transfer guidelines.

Inter-hospital transfer: the crux of the trauma system, a curse for trauma registries

The inter-hospital transfer of patients is crucial to a well functioning trauma system, and the transfer process may serve as a quality indicator for regional trauma care. However, the assessment of the transfer process requires high-quality data from various sources. Prospective studies and studies based on single-centre trauma registries may fail to capture an appropriate width and depth of data. Thus the creation of inclusive regional and national trauma registries that receive information from all of the services within a trauma system is a prerequisite for high quality inter-hospital transfer studies in the future.
