Dutch trauma system performance: Are injured patients treated at the right place?

BackgroundThe goal of trauma systems is to match patient care needs to the capabilities of the receiving centre. Severely injured patients have shown better outcomes if treated in a major trauma centre (MTC). We aimed to evaluate patient distribution in the Dutch trauma system. Furthermore, we sought to identify factors associated with the undertriage and transport of severely injured patients (Injury Severity Score (ISS) >15) to the MTC by emergency medical services (EMS).MethodsData on all acute trauma admissions in the Netherlands (2015-2016) were extracted from the Dutch national trauma registry. An ambulance driving time model was applied to calculate MTC transport times and transport times of ISS >15 patients to the closest MTC and non-MTC. A multivariable logistic regression analysis was performed to identify factors associated with ISS >15 patients’ EMS undertriage to an MTC.ResultsOf the annual average of 78,123 acute trauma admissions, 4.9% had an ISS >15. The nonseverely injured patients were predominantly treated at non-MTCs (79.2%), and 65.4% of patients with an ISS >15 received primary MTC care. This rate varied across the eleven Dutch trauma networks (36.8%-88.4%) and was correlated with the transport times to an MTC (Pearson correlation -0.753, p=0.007). The trauma networks also differed in the rates of secondary transfers of ISS >15 patients to MTC hospitals (7.8% - 59.3%) and definitive MTC care (43.6% - 93.2%). Factors associated with EMS undertriage of ISS >15 patients to the MTC were female sex, older age, severe thoracic and abdominal injury, and longer additional EMS transport times.ConclusionsApproximately one-third of all severely injured patients in the Netherlands are not initially treated at an MTC. Special attention needs to be directed to identifying patient groups with a high risk of undertriage. Furthermore, resources to overcome longer transport times to an MTC, including the availability of ambulance and helicopter services, may improve direct MTC care and result in a decrease in the variation of the undertriage of severely injured patients to MTCs among the Dutch trauma networks. Furthermore, attention needs to be directed to improving primary triage guidelines and instituting uniform interfacility transfer agreements.     

Disparities in access to trauma care in the United States: A population-based analysis

BackgroundInjury is a major contributor to morbidity and mortality in the United States. Accordingly, expanding access to trauma care is a Healthy People priority. The extent to which disparities in access to trauma care exist in the US is unknown. Our objective was to describe geographic, demographic, and socioeconomic disparities in access to trauma care in the United States.MethodsCross-sectional study of the US population in 2010 using small units of geographic analysis and validated estimates of population access to a Level I or II trauma center within 60 minutes via ambulance or helicopter. We examined the association between geographic, demographic, and socioeconomic factors and trauma center access, with subgroup analyses of urban-rural disparities.ResultsOf the 309 million people in the US in 2010, 29.7 million lacked access to trauma care. Across the country, areas with higher income were significantly more likely to have access (OR 1.30, 95% CI 1.12–1.50), as were major cities (OR 2.13, 95% CI 1.25–3.62) and suburbs (OR 1.27, 95% CI 1.02–1.57). Areas with higher rates of uninsured (OR 0.09, 95% CI 0.07–0.11) and Medicaid or Medicare eligible patients (OR 0.69, 95% CI 0.59–0.82) were less likely to have access. Areas with higher proportions of blacks and non-whites were more likely to have access (OR 1.37, 95% CI 1.19–1.58), as were areas with higher proportions of Hispanics and foreign-born persons (OR 1.51, 95% CI 1.13–2.01). Overall, rurality was associated with significantly lower access to trauma care (OR 0.20, 95% CI 0.18–0.23).ConclusionWhile the majority of the United States has access to trauma care within an hour, almost 30 million US residents do not. Significant disparities in access were evident for vulnerable populations defined by insurance status, income, and rurality.     

Access to specialist hospital care and injury survivability: identifying opportunities through an observational study of prehospital trauma fatalities

BackgroundOf the five million injury deaths that occur globally each year, an estimated 70% occur before the injured person reaches hospital. Although reducing the time from injury to definitive care has been shown to achieve better outcomes for patients, the relationship between injury incident location and access to specialist care has been largely unexplored.ObjectiveTo determine the number and distribution of prehospital (on-scene/en route) trauma deaths without timely access to a hospital with surgical and intensive care capabilities, overall and by estimated injury survivability.MethodsNew Zealand's Mortality Collection and Hospital Discharge dataset were used to select prehospital injury deaths in 2009-2012. These records were linked to files held by Australasia's National Coronial Information Service (NCIS) to estimate, for the trauma subset, injury survivability. Using geographical locations of injury for the prehospital trauma fatalities, time from Emergency Medical System call-out to arrival at the closest specialist hospital was estimated.ResultsOf 1,752 prehospital trauma fatalities, 14.7% (95%CI 13.0, 16.4) had potentially survivable injuries that occurred in locations without timely access (prehospital phase >60 minutes). More than half (132 of 257) of the potentially survivable prehospital trauma fatalities without timely access died as a result of a motor vehicle traffic crash. Only 10% (95%CI 5.7, 16.0) of prehospital trauma fatalities from falls were estimated to be potentially survivable and without timely access compared to 24.6% (95%CI 18.5, 31.5) of prehospital firearm fatalities. Through using geospatial techniques, “hot spot” locations of potentially survivable injuries without timely access to specialist major trauma hospitals were apparent.ConclusionApproximately 15% of prehospital trauma fatalities in New Zealand that are potentially survivable occur in locations without timely access to advanced level hospital care. Continued emphasis is required on both improving timely access to advanced trauma care, and on primary prevention of serious injuries. Decisions regarding trauma service delivery, a modifiable system-level factor, should consider the geographic distribution of locations of these injury events alongside the resident population distribution.     

Evolution, not revolution: splenic salvage for blunt trauma in a statewide voluntary trauma system--a 10-year experience

BACKGROUND: State-legislated trauma systems have been enacted in an attempt to improve trauma care. Blunt splenic injury incidence without a legislated trauma system was examined for changes in care with a hypothesis that a voluntary system may perform equally with a legislated system. METHODS: Data from a statewide discharge database for the years 1993 to 2002 were examined. RESULTS: There were 276,425 trauma admissions overall, with blunt splenic injury occurring in 1.76%. Average Injury Severity Score (ISS) increased in trauma centers and decreased in the community. Trauma centers (TC) had more multisystem injuries. Splenic injury diagnosis increased 44% in TC between the early and late periods but only 7% in community facilities. Splenectomies increased 16% in TC but declined 16% in community hospital. Splenic salvage rate improved at both types of facilities. CONCLUSIONS: Splenic salvage rates improved over time in hospitals with no formal trauma system. Community hospitals cared for more than 50% of splenic injuries but transferred complex multisystem injuries, including splenic injuries, suggesting evolving care. Non-invasive imaging has increased the recognition of splenic injuries in both community hospitals and TC. Splenectomies are performed less, but have increased in TC with increasing ISS scores.     

Clinical Spectrum of Trauma at a University Hospital in Nigeria

Background and Objectives: Data on trauma in Nigeria requires updating just as trauma care needs coordination and organization. This study was done to examine the clinical spectrum of trauma and to propose measures for organization of trauma care. Patients and Methods: A 2-year prospective report of an ongoing trauma research is presented. Data obtained from September 1999 to December 2000) include name, age, sex, presenting diagnosis at the accident and emergency (A and E) unit, injury-arrival time, ode of transportation of patients to the hosptial, and the outcome of care. Results: Trauma patients comprised 2,913 of the 4,164 (70.0%) surgical patients seen in the A and E but 129 of 171 deaths (75.4%). Types of trauma were lacerations (585 patients, 20.1%), fractures (542, 18.7%), head injury (250, 8.6%), multiple injuries (249, 8.6%), burns (159, 5.5%), and others. Road traffic accidents (RTA) occurred in 1,816 patients (62.3%), falls in 308, assaults in 258, burns in 159, home accidents in 122, gunshot injuries in 107, industrial accidents in 73, and foreign body injuries in 70. There was no pre-hospital care. Transport to the A and E was done by relations, the police and a few Good Samaritans. Most of the patients reached the hospital in < 6 h. Common mortalities were from head injury (37 patients, 28.7%), multiple injuries (35, 27.1%), fractures (12, 9.3%), and burns (9, 7.0%). Of 106 deaths with timed records, 22 (20.7%), 56 (53.0%) and 28 (26.3%) occurred in 0–1 h, > 1–24 h and > 24 h, respectively. Conclusions: The spectrum of trauma is predominantly RTA-related, hence, trauma care organization would include prevention of RTA, organization of pre-hospital care aimed at transport time of < 2h, training volunteers from the populace and the police as emergency medical services technicians for resuscitation during transport and getting patients to hospital in optimal state, and an enhanced in-hospital care by designation and categorization of hospitals. These strategies, including continuous trauma research and funding, would go a long way in reducing mortalities from trauma, especially from RTA.

Evaluation of the survival benefit of Trauma-Centre care in the Italian setting

Background

Trauma Centres (TC) are expected to have a lower mortality – after controlling for injury-severity – than non-designated hospitals in order to justify their funding. This benefit has been demonstrated in the USA not long ago, while the evidence from other settings is still limited. We evaluated the mortality benefit of TC care in an Italian setting, where the first Trauma System with designated TCs was instituted six years ago.

Materials and methods

We compared 30-day mortality among 4059 severely injured patients treated in the three TCs and in 12 other hospitals of the region Emilia-Romagna, Italy between 2007 and 2011. We used propensity-score weighting to adjust for differences in potential confounders.

Results

In the overall population there was no difference in the adjusted mortality – OR (95% CI) 1.02 (0.81–1.29). However, an interaction existed between TC care and injury severity. Subgroup analyses showed that the benefit of TC care was significant for the patients with a TMPM-ICD9 severity score > 0.12 – OR (95% CI) 0.70 (0.52–0.97). These patients comprised about one-third of the study population. Further subgroup investigations showed that this effect was concentrated in the patients with less than 45 years.

Conclusions

The risk of death for patients with particularly severe injuries is significantly lower when they are treated in TCs as compared to Non-Trauma Centres, especially if they are younger than 45 years. TC care should be provided to a larger number of patients than currently done.     

Direct transport versus inter hospital transfer of severely injured trauma patients

IntroductionSeveral studies have suggested that severely injured patients should be transported directly to a trauma centre bypassing the nearest hospital. However, the evidence remains inconclusive. The purpose of this study was to examine the benefits in terms of mortality of direct transport to a trauma centre versus primary treatment in a level II or III centre followed by inter hospital transfer to a trauma centre for severely injured patients without Traumatic Brain Injury (TBI).Patients and methodsWe used the regional trauma registry and included all patients with an Injury Severity Score (ISS) >15 and an Abbreviated Injury Score <4 for head injury. We adjusted for survival bias by including “potential transfers”: patients who died at the nearest hospitals before transportation to a trauma centre.ResultsA total of 439 patients was included. The majority of patients (349/439, 79%) was transported directly to the level I trauma centre (direct group). The transferred group was formed by the remaining 90 patients, of whom 81 were transferred to the level I trauma centre after initial stabilisation elsewhere and 9 patients died in the emergency room before transfer to a level 1 trauma centre could occur. There were no significant differences in baseline and injury characteristics between the groups. Overall, 60 patients died in-hospital including 41 of the 349 patients (12%) in the direct group and 19 of the 90 patients (21%) in the transferred group. Nine of the 19 deaths in the transferred group were ascribed to potential transfers. After adjusting for prehospital Revised Trauma Score (RTS) and ISS, the odds ratio of death was 2.40 (95%CI: 1.07–5.40) for patients in the transfer group. When potential transfer patients were excluded from the analysis, the adjusted odds ratio of death was 1.14 (95%CI: 0.43–3.01).ConclusionsAfter adjusting for survivor bias by including potential transfers, the results of this study suggest a lower risk of death for patients who are directly transported to a level I trauma centre than for patients who receive primary treatment in a level II or III centre and are transferred to a trauma centre. However, this finding was only significant when adjusting for survival bias and therefore we conclude that it is still uncertain if there is a lower risk of death for patients who are transported directly to a level I trauma centre.     

External benchmarking of trauma services in New South Wales: Risk-adjusted mortality after moderate to severe injury from 2012 to 2016

Background

Trauma centres and systems have been associated with improved morbidity and mortality after injury. However, variability in outcomes across centres within a given system have been demonstrated. Performance improvement initiatives, that utilize external benchmarking as the backbone, have demonstrated system-wide improvements in outcomes. This data driven approach has been lacking in Australia to date. Recent improvement in local data quality may provide the opportunity to engage in data driven performance improvement. Our objective was to generate risk-adjusted outcomes for the purpose of external benchmarking of trauma services in New South Wales (NSW) based on existing data standards.

Beliefs and expectations of rural hospital practitioners towards a developing trauma system: A qualitative case study

BackgroundAn understanding of stakeholders’ views is key to the successful development and operation of a rural trauma system. Scotland, which has large remote and rural areas, is currently implementing a national trauma system. The aim of this study was to identify key barriers and enablers to the development of an effective trauma system from the perspective of rural healthcare professionals.MethodsThis is a qualitative study, which was conducted in rural general hospitals (RGH) in Scotland, from April to June 2017. We used an opportunistic sampling strategy to include hospital providers of rural trauma care across the region. Semi-structured interviews were conducted, recorded, and transcribed. Thematic analysis was used to identify and group participant perspectives on key barriers and enablers to the development of the new trauma system.ResultsWe conducted 15 interviews with 18 participants in six RGHs. Study participants described barriers and enablers across three themes: 1) quality of care, 2) interfaces within the system and 3) interfaces with the wider healthcare system. For quality of care, enablers included confidence in basic trauma management, whilst a perceived lack of change from current management was seen as a barrier. The theme of interfaces within the system identified good interaction with other services and a single point of contact for referral as enablers. Perceived barriers included challenges in referring to tertiary care. The final theme of interfaces with the wider healthcare system included an improved transport system, increased audit resource and coordinated clinical training as enablers. Perceived barriers included a rural staffing crisis and problematic patient transfer to further care.ConclusionsThis study provides insight into rural professionals’ perceptions regarding the implementation of a trauma system in rural Scotland. Barriers included practical issues, such as retrieval, transfer and referral processes. Importantly, there is a degree of uncertainty, discontent and disengagement towards trauma system development, and concerns regarding staffing levels and governance. These issues are unlikely to be unique to Scotland and warrant further study to inform service planning and the effective delivery of rural trauma systems.     

Identification of thoracic injuries by emergency medical services providers among trauma patients

IntroductionSevere thoracic injuries are time sensitive and adequate triage to a facility with a high-level of trauma care is crucial. The emergency medical services (EMS) providers are required to identify patients with a severe thoracic injury to transport the patient to the right hospital. However, identifying these patients on-scene is difficult. The accuracy of prehospital assessment of potential thoracic injury by EMS providers of the ground ambulances is unknown. Therefore, the aim of this study is to evaluate the diagnostic accuracy of the assessment of the EMS provider in the identification of a thoracic injury and determine predictors of a severe thoracic injury.MethodsIn this multicentre cohort study, all trauma patients aged 16 and over, transported with a ground erence standard. Prehospital variables were analysed using logistic regression to explore prehospital ambulance to a trauma centre, were evaluated. The diagnostic value of EMS provider judgment was determined using the Abbreviated Injury Scale (AIS) of ≥ 1 in the thoracic region as ref predictors of a severe thoracic injury (AIS ≥ 3).ResultsIn total 2766 patients were included, of whom 465 (16.8%) sustained a thoracic injury and 210 (7.6%) a severe thoracic injury. The EMS providers’ judgment had a sensitivity of 54.8% and a specificity of 92.6% for the identification of a thoracic injury. Significant independent prehospital predictors were: age, oxygen saturation, Glasgow Coma Scale, fall > 2 m, and suspicion of inhalation trauma or a thoracic injury by the EMS provider.ConclusionEMS providers could identify little over half of the patients with a thoracic injury. A supplementary triage protocol to identify patients with a thoracic injury could improve prehospital triage of these patients. In this supplementary protocol, age, vital signs, and mechanism criteria could be included.     

Effect of direct and indirect transfer status on trauma mortality in sub Saharan Africa

IntroductionTraumatic injuries account for the greatest portion of global surgical burden particularly in low- and middle-income countries (LMICs). To assess effectiveness of a developing trauma system, we hypothesize that there are survival differences between direct and indirect transfer of trauma patients to a tertiary hospital in sub Saharan Africa.MethodsRetrospective analysis of 51,361 trauma patients within the Kamuzu Central Hospital (KCH) trauma registry from 2008 to 2012 was performed. Analysis of patient characteristics and logistic regression modelling for in-hospital mortality was performed. The primary study outcome is in hospital mortality in the direct and indirect transfer groups.ResultsThere were 50,059 trauma patients were included in this study. 6578 patients transferred from referring facilities and 43,481 patients transported from the scene. The indirect and direct transfer cohorts were similar in age and sex. The mechanism of injury for transferred patients was 78.1% blunt, 14.5% penetrating, and 7.4% other, whereas for the scene group it was 70.7% blunt, 24.0% penetrating, and 5.2% other. Median times to presentation were 13 (4–30) and 3 (1–14) h for transferred and scene patients, respectively. Mortality rate was 4.2% and 1.6% for indirect and direct transfer cohorts, respectively. A total of 8816 patients were admitted of which 3636 and 5963 were in the transfer and scene cohort, respectively. After logistic regression analysis, the adjusted in-hospital mortality odds ratio was 2.09 (1.24–3.54); P = 0.006 for indirect transfer versus direct transfer cohort, after controlling for significant covariates.ConclusionsDirect transfer of trauma patients from the scene to the tertiary care centre is associated with a survival benefit. Our findings suggest that trauma education and efforts directed at regionalization of trauma care, strengthening pre-hospital care and timely transfer from district hospitals could mitigate trauma-related mortality in a resource-poor setting.     

The impact of the Major Trauma Network: will trauma units continue to treat complex foot and ankle injuries?

IntroductionApril 1st 2012 saw the introduction of National Trauma Networks in England. The aim to optimise the management of major trauma. Patients with an ISS ≥ 16 would be transferred to the regional Major Trauma Centre (level 1). Our premise was that trauma units (level 2) would no longer manage complex foot and ankle injuries thereby obviating the need for a foot and ankle specialist service.MethodsRetrospective analysis of the epidemiology of foot and ankle injuries, using the Gloucestershire trauma database, from a trauma unit with a population of 750,000. Rates of open fractures, complex foot and ankle injuries and requirement for stabilisation with external fixation were reviewed before and after the introduction of the regional Trauma Network. Secondly, using the Trauma Audit & Research Network (TARN) database, all foot and ankle injuries triaged to the regional Major Trauma Centre (MTC) were reviewed.ResultsIncidence of open foot and ankle injuries was 2.9 per 100,000 per year. There were 5.1% open injuries before the network and 3.2% after (p > 0.05). Frequency of complex foot and ankle injuries was 4.2% before and 7.5% after the network commenced, showing no significant change. There was no statistically significant change in the numbers of patients with complex foot and ankle injuries treated by application of external fixators. Analysis of TARN data revealed that only 18% of patients with foot and ankle injuries taken to the MTC had an ISS ≥ 16. The majority of these patients were identified as requiring plastic surgical intervention for open fractures (69%) or were polytrauma patients (43%). Only 4.5% of patients had isolated, closed foot and ankle injuries.ConclusionWe found that at the trauma unit there was no decrease in the numbers of complex foot and ankle injuries, open fractures, or the applications of external fixators, following the introduction of the Trauma Network. These patients will continue to attend trauma units as they usually have an ISS < 16. Our findings suggest that there is still a need for foot and ankle specialists at trauma units, in order to manage patients with complex foot and ankle injuries.     

Development of a novel Global Trauma System Evaluation Tool and initial results of implementation in the Republic of South Sudan

IntroductionTrauma remains a leading cause of death and disability in the world, and trauma systems decrease mortality from trauma. We developed the Global Trauma System Evaluation Tool (G-TSET) specifically for use in low- and middle-income countries (LMICs). The Sudan People's Liberation Army (SPLA) in the Republic of South Sudan (RSS) desires a military trauma system (MTS) which allowed us to pilot the G-TSET.MethodsThe G-TSET was developed by modifying key components of a trauma system applicable to LMICs. We partnered with the SPLA Medical Corps using clinical collaboration, direct observation, and discussion groups. Benchmarks and indicators were scored with 5 indicating “full capability” and 1 meaning “not present” and were used to develop a SPLA MTS plan.ResultsThe overall MTS score was 1.15 indicating an urgent need for system development. The assessment highlighted the need for SPLA Command support. Battlefield care, transport to a trauma facility, and inter-facility communication were identified for improvement. After essential battlefield care, consisting primarily of bandaging and splinting, transport times for injured SPLA soldiers were 12 h to 3 days by truck. Based on our findings, we collaborated with SPLA medical leadership to develop a plan to develop a formal MTS.ConclusionWe piloted a novel trauma system assessment tool for the MTS in the RSS. Qualitatively, we identified gaps in the MTS and provided the medical leadership with a plan for improvement. We anticipate a short-term follow-up to quantify improvement, and we seek to validate this tool for use in other countries.     

IS PENETRATING INJURY ON THE INCREASE IN SOUTH-WESTERN SYDNEY?

Background: Few Australian studies describe the epidemiology of penetrating trauma. This study describes the incidence and demographic features of penetrating injuries with emphasis on trends and severity analysis. Methods: Case analysis was performed utilizing data from the Liverpool Hospital Trauma Registry (1989–94). NSW Department of Health Hospital Separations (1991–93), and the NSW Bureau of Crime Statistics (1991–93) with reference to the Liverpool and Fairfield Local Government Areas (LGA). Results: The Trauma Registry revealed 251 of penetrating trauma. The median age was 26 years (interquartile range 21–33). Ninety-one per cent of the victims were male. Fourteen per cent of patients had an Injury Severity Score (ISS) > 15. Sixty-five per cent of cases were stab injuries and 20% gunshot injuries with the abdomen being the most commonly injured site. Twenty-one per cent of patients underwent laparotomy, 1.6% thoracotomy and 1.2% thoracotomy and laparatomy. There were 10 (4%) deaths. Trends in incidence of penetrating trauma and violent crime involving weapons were analysed. Static trends were observed for the annual incidence of penetrating trauma from the Liverpool Hospital Trauma Registry. Separations for penetrating trauma from Liverpool and Fairfield hospitals showed a slightly increasing trend. Violent crimes involving weapons in the Liverpool and Fairfield LGA showed a static trend. Nevertheless, separations for penetrating trauma and rates of violent crimes involving weapons were higher in south-western Sydney than metropolitan Sydney or NSW. Eight per cent of the LGA population are Vietnamese but this study identified 16% of victims as being Vietnamese. Conclusions: This study found no significant increase in penetrating trauma or violent crime predisposing to penetrating injury in south-western Sydney.     

Pathways and factors that influence time to definitive trauma care for injured children in New South Wales,Australia

BackgroundTimely definitive paediatric trauma care influences patient and parental physical and emotional outcomes. New South Wales (NSW) covers a large geographical area with all three NSW paediatric trauma centres (PTC) located in two approximated major cities, meaning it is inevitable that some injured children receive initial treatment locally and then require transfer. Little is known about the factors that then impact timely arrival of injured children to definitive care.MethodsThis included children admitted between July 2015 and September 2016, <16 years with an injury severity (ISS) ≥9; or requiring intensive care admission; or deceased following injury. Children were identified through the three PTCs, NSW Trauma Registry and NSW Medical Retrieval Registry.ResultsThere were 593 children admitted following injury and 46% required transfer to a PTC. There was no significant difference in age, ISS, ICU admission or head injury (AIS >2) between transferred and directly transported cohorts. There were significant differences in mechanism of injury between the two groups (χ²(9) = 45.9, p < 0.001). The median (IQR) time to book a transfer from arrival at the referring facility, was 146.5 (86–238) minutes. Time from injury to arrival at the PTC more than doubled for children transferred, with significant and unwarranted variability between transporting agencies resulting in unwarranted delays to surgical intervention. For example, time spent at the referring facility by Aeromedical Retrieval Service was less than half that of the Newborn & paediatric Emergency Transport Service [53 (IQR:47–61) vs 115 (84–155) minutes (p <0.001)].ConclusionClinicians caring for paediatric trauma patients in facilities outside trauma centres require the capability and opportunity to identify and notify early those requiring transfer for ongoing management. The provision of a streamlined referral and transfer process for all paediatric trauma patients requiring treatment in NSW PTCs would reduce the burden on the referring facility, reduce variation amongst transport providers and improve time to definitive care.     

Disparities in trauma care education: An observational study of the ATLS course within a national trauma system

BackgroundDisparities in trauma systems, including gaps between trauma center levels, affect patient outcomes. Advanced Trauma Life Support (ATLS) is a standard method of care that improves the performance of lower-level trauma systems. We sought to study potential gaps in ATLS education within a national trauma system.MethodsThis prospective observational study examined the characteristics of 588 surgical board residents and fellows taking the ATLS course. The course is required for board certification in adult trauma specialties (general surgery, emergency medicine, and anesthesiology), pediatric trauma specialties (pediatric emergency medicine and pediatric surgery), and trauma consulting specialties (all other surgical board specialties). We compared the differences in course accessibility and success rates within a national trauma system which includes seven level 1 trauma centers (L1TC) and twenty-three non-level 1 hospitals (NL1H).ResultsResident and fellow students were 53% male, 46% employed in L1TC, and 86% were in the final stages of their specialty program. Only 32% were enrolled in adult trauma specialty programs. Students from L1TC had a 10% higher ATLS course pass rate than NL1H (p = 0.003). Trauma center level was associated with higher odds to pass the ATLS course, even after adjustment to other variables (OR = 1.925 [95% CI = 1.151 to 3.219]). Compared to NL1H, the course was two-three times more accessible to students from L1TC and 9% more accessible to adult trauma specialty programs (p = 0.035). The course was more accessible to students at early levels of training in NL1H (p < 0.001). Female students and trauma consulting specialties enrolled in L1TC programs were more likely to pass the course (OR = 2.557 [95% CI = 1.242 to 5.264] and 2.578 [95% CI = 1.385 to 4.800], respectively).ConclusionsPassing the ATLS course is affected by trauma center level, independent of other student factors. Educational disparities between L1TC and NL1H include ATLS course access for core trauma residency programs at early training stages. Some gaps are more pronounced among consulting trauma specialties and female surgeons. Educational resources should be planned to favor lower-level trauma centers, specialties dealing in trauma care, and residents early in their postgraduate training.     

Air transport following surgical stabilization: an extension of regionalized trauma care

A 30-month retrospective review was performed of all trauma patients initially evaluated and operatively stabilized at Level III hospitals, with subsequent specialized air transport within 48 hours of injury to the regional Level I trauma center in Seattle. Nineteen patients were identified, with a mean ISS of 44 (range, 20-66). Mean transport time and distance were 2.4 hours and 456 miles, respectively. The estimated average ground transport time for the same patients was 23.8 hours. No deaths occurred during transport, and the overall survival rate was 58%. Transport charges averaged $4,162, which was 14% of the complete hospitalization cost. We conclude that: 1) patient survival after air transport was no different than that predicted for trauma victims with immediate access to a trauma center; 2) postoperative hemodynamic instability predicted a poor outcome; 3) the higher cost of air relative to ground transport is outweighed by significant time savings in these critically injured patients; and 4) air transport following operative stabilization represents an extension of regionalized trauma care to the isolated areas of Washington and Alaska.     

The trauma registry compared to All Patient Refined Diagnosis Groups (APR-DRG)

BackgroundLiterature has shown there are significant differences between administrative databases and clinical registry data. Our objective was to compare the identification of trauma patients using All Patient Refined Diagnosis Related Groups (APR-DRG) as compared to the Trauma Registry and estimate the effects of those discrepancies on utilization.MethodsAdmitted pediatric patients from 1/2012–12/2013 were abstracted from the trauma registry. The patients were linked to corresponding administrative data using the Pediatric Health Information System database at a single children’s hospital. APR-DRGs referencing trauma were used to identify trauma patients. We compared variables related to utilization and diagnosis to determine the level of agreement between the two datasets.ResultsThere were 1942 trauma registry patients and 980 administrative records identified with trauma-specific APR-DRG during the study period. Forty-two percent (816/1942) of registry records had an associated trauma-specific APR-DRG; 69% of registry patients requiring ICU care had trauma APR-DRGs; 73% of registry patients with head injuries had trauma APR-DRGs. Only 21% of registry patients requiring surgical management had associated trauma APR-DRGs, and 12.5% of simple fractures had associated trauma APR-DRGs.ConclusionAPR-DRGs appeared to only capture a fraction of the entire trauma population and it tends to be the more severely ill patients. As a result, the administrative data was not able to accurately answer hospital or operating room utilization as well as specific information on diagnosis categories regarding trauma patients.

Characteristics of trauma patients that leave against medical advice: An eight-year survey analysis using the National Hospital Ambulatory Medical Care Survey, 2009–2016

BackgroundLeaving against medical advice (AMA) is associated with increased readmission rates, fragmented patient care, and healthcare litigation. Understanding the factors associated with trauma patients leaving AMA from acute care settings will help guide better communication with trauma patients and improve patient satisfaction. This study aims to assess the sociodemographic and in-hospital care characteristics of trauma patients that leave AMA from acute care centers across the U.S.MethodsWe pooled and analyzed eight years of data (2009–2016) from the National Hospital Ambulatory Medical Care Survey. The outcome variable was whether the patient left AMA or not. The main predictors were the triage class, weekend presentation, health insurance status, the presence of chronic diseases, and the receipt of therapeutic and diagnostic procedures. The sociodemographic characteristics -age, sex, and race/ethnicity, were measured as potential confounders in the developed model. We performed logistic regression and reported the unadjusted and adjusted odds of leaving AMA as well as the 95% confidence intervals.ResultsThe weighted percent of the trauma patient population that left AMA was 1.8%. The odds of leaving AMA decreased with advancing age, and increased among non-Hispanic Blacks, compared with non-Hispanic Whites. After adjusting for age, race, and gender, the odds of leaving AMA increased among patients that lacked health insurance (AOR: 1.86; 95% CI: 1.51–2.31), and had diagnostic procedures (AOR: 2.79; 95% CI: 2.32–3.36). The odds of leaving AMA reduced among trauma patients who were classified as emergent (AOR: 0.70; 95% CI: 0.50–0.98) and had therapeutic procedures (AOR: 0.39; 95% CI: 0.32–0.47).ConclusionPredicting trauma patients with increased odds of leaving AMA will inform intentional communication that may reduce leaving AMA rates and improve care.     

Management of paediatric splenic injury in the New South Wales trauma system

Since the 1980’s, paediatric surgeons have increasingly managed blunt splenic injury (BSI) in children non-operatively. However, studies in North America have shown higher operation rates in non-paediatric centres and by adult surgeons. This association has not been examined elsewhere.ObjectiveTo investigate the management of BSI in New South Wales (NSW) children, to determine the patient and hospital factors related to the odds of operation. Secondarily, to investigate whether the likelihood of operation varied by year.MethodsChildren age 0–16 admitted to a NSW hospital between July 2000 and December 2011 with a diagnosis of BSI were identified in the NSW Admitted Patient Data Collection, and linked to deaths data from Registry of Births Deaths and Marriages, and Bureau of Statistics. The operation rate was calculated and compared between different hospital types. Univariable analysis was used to determine patient and hospital factors associated with operative management. The difference in the odds of operation between the oldest data (July 2000–December 2005) and most recent (January 2006–December 2011) was also examined. Multivariable logistic regression with stepwise elimination was then performed to determine likelihood of operative management according to hospital category and era, adjusting for potential confounders.Results955 cases were identified, with 101(10.6%) managed operatively. On multivariable analysis, factors associated with operation included age (OR 1.11, 95% CI 1.01–1.18, p < 0.05), massive splenic disruption (OR 3.10, 95% CI 1.61–6.19, p < 0.001), hollow viscus injury (OR 11.03, 95% CI 3.46–34.28, p < 0.001) and transfusion (OR 7.70, 95% CI 4.54–13.16, p < 0.001). Management outside a paediatric trauma centre remained significantly associated with operation, whether it be metropolitan adult trauma centre (OR 4.22 95% CI 1.70–10.52, p < 0.01), rural trauma centre (OR 3.72 95% CI 1.83–7.83, p < 0.001) or metropolitan local hospital (OR 5.23, 95% CI 1.22–18.93 p < 0.05). Comparing the 2 eras, the overall operation rate fell, although not significantly, from 12.9% to 8.7% (OR 1.3, 95% CI 0.89–243 p = 0.13)ConclusionWhile Paediatric Surgeons have wholeheartedly adopted non-operative management, away from paediatric centres, children in NSW are still being operated on for BSI unnecessarily. While the factors at play may be complex, further evaluation of the management and movement of injured children within the broad NSW trauma system is required.
