Maritime Interfacility Transport of Two Laboring Mothers - A Case Report.

Background: Interfacility transport of laboring mothers is an infrequent endeavor associated with additional risk in the best of circumstances. Case Presentation: We report on a case where two laboring mothers were transported at night via fireboat, resulting in the delivery of one child while underway and delivery of another soon after arrival at the receiving facility. Conclusions: The objective of this case report is to describe the decision-making process and medical care for these two mothers during a nontraditional EMS transport.

Reduction in Interfacility Transfer Response Time after Implementation of an AutoLaunch Protocol.

Background: Interfacility transfers (IFTs) are an essential component of healthcare systems to allow movement of patients between facilities. It is essential to limit any delays in patients receiving the care they require at the receiving facility. The primary objective of this study was to assess whether IFT response time was reduced after implementation of an AutoLaunch protocol, in which an ambulance is dispatched to the sending facility prior to acceptance of the patient by the receiving facility. The secondary objective was to describe the frequency and amount of time ambulances had to stage outside the sending facility in situations where the ambulance arrived prior to the patient being accepted by the receiving facility. Methods: This was a retrospective pre-post analysis of patients undergoing IFT for services not available at the sending facility between October 1, 2018 and September 30, 2019, with the AutoLaunch protocol being implemented on March 25, 2019. IFT response time was defined as the time the transfer request was initially made to the time the ambulance arrived at the sending facility. Dispatch call logs and transport records were analyzed before and after implementation of the AutoLaunch protocol to assess for a difference in IFT response time as well as frequency and amount of time ambulances had to stage. Results: Of 1,881 IFTs analyzed, 885 (47.0%) were completed under the traditional protocol and 996 (53.0%) were completed under the AutoLaunch protocol. The median IFT response time under the traditional protocol was 27.5 minutes (interquartile range (IQR): 17.9, 43.3), compared with 19.9 minutes (IQR: 12.8, 28.2) under the AutoLaunch protocol (p < 0.01), representing a 27.6% reduction in response time, or 7.6 minutes saved. Of the 996 AutoLaunch transfers, there were 215 incidents (21.6%) in which the IFT ambulance had to stage, and the median staging time was 10.1 minutes (IQR: 4.9, 24.2). Conclusions: Implementation of our AutoLaunch protocol resulted in a significant reduction in ambulance response time for interfacility transfers. Further studies are needed to assess whether the reduction in response time is associated with improved patient outcomes for certain conditions.

Patient Care Alterations After Point-of-Care Laboratory Testing During Critical Care Transport.

OBJECTIVE: Point-of-care laboratory testing (POCT) is associated with a reduced time to testing results and critical decision making within emergency departments. POCT is an essential clinical assessment tool because laboratory data are used to support timely critical decisions regarding acute medical conditions onditions ; however, there is currently limited research to support the use of POCT in the critical care transport environment. Few studies have evaluated the changes in patient care that occur after POCT during critical care transport. This study aims to contribute to the limited data available correlating prehospital POCT and changes in patient care. METHODS: After institutional review board approval, a retrospective review of patients transported by a critical care transport team between October 1, 2013 and September 31, 2015 was completed. During the study period, 11,454 patients were transported, and 632 (5.51%) received POCT testing. RESULTS: Patient care changes were noted in 244 (38.6%) patient tests. The most frequent patient care alterations were ventilator settings (10.9%), electrolyte changes (10.4%), and unit bed upgrades (7.1%). POCT most frequently altered care for patients with post-cardiac arrest syndrome (64.7%), sepsis/septic shock (61.8%), diabetic ketoacidosis (54.5%), or pneumonia (49.3%). CONCLUSION: Patient care alterations occurred in 38.6% of patients undergoing POCT. Patient care was most frequently changed when patients were diagnosed with post-arrest, sepsis/septic shock, diabetic ketoacidosis, and pneumonia.

Impact of Prepatching on Paramedic In-Hospital Times for Emergent Interfacility Transfers.

Background: The care required for patients at times necessitates they be transferred to another hospital capable of providing specialized care, a process known as an interfacility transfer. Delays to appropriate care for critically ill patients are associated with increased morbidity and mortality. Improving efficiencies in interfacility transport process can thus expedite the time to critical treatment. Traditionally paramedics would patch to a transport medicine physician (TMP) after initial patient contact to discuss the case and expected management during transport. The concept of prepatch shifts this discussion between the TMP and paramedics prior to initial patient contact. The objective of this study was to assess if prepatching with paramedics prior to arrival at the patient reduced the in-hospital time for emergent interfacility transfers transported by a provincial critical care transport organization. Methods: This was a retrospective cohort study of all emergent, adult interfacility transports for patients transported by a provincial critical care transport organization in Ontario, Canada from January 2016 to December 2019. Quantile regression was used to evaluate the impact of prepatching as well as patient and paramedic characteristics on paramedic in-hospital time. Results: A total of 10,088 patients were included in the study, with 3,606 patients having a prepatch conducted and 6,482 without. Ventilated patients and vasopressor use were associated with higher prepatch rates; with the use of prepatch in these patients increasing over subsequent years of the study. Additionally, patients requiring higher levels of care, including being mechanically ventilated or dependent on vasopressors, were associated with longer in-hospital times. Prepatching reduced in-hospital time by 4 minutes at the 90th quantile across all patients. Conclusion: Prepatching reduced paramedic in-hospital time for emergent interfacility transports. Although the clinical impact of this reduction in time is uncertain, prepatching may serve in facilitating shared mental modeling between paramedics and TMPs which may be beneficial to patient safety and team performance.

Time to specialty care and mortality after cardiac arrest.

INTRODUCTION: Out of hospital cardiac arrest (OHCA) patients are often transported to the closest emergency department (ED) or cardiac center for initial stabilization and may be transferred for further care. We investigated the effects of delay to transfer on in hospital mortality at a receiving facility. METHODS: We included OHCA patients transported from the ED by a single critical care transport service to a quaternary care facility between 2010 and 2018. We calculated dwell time as time from arrest to critical care transport team contact. We abstracted demographics, arrest characteristics, and interventions started prior to transport arrival. For the primary analysis, we used logistic regression to determine the association of dwell time and in-hospital mortality. As secondary outcomes we investigated for associations of dwell time and mortality within 24 h of arrival, proximate cause of death among decedents, arterial pH and lactate on arrival, sum of worst SOFA subscales within 24 h of arrival, and rearrest during interfacility transport. RESULTS: We included 572 OHCA patients transported from an outside ED to our facility. Median dwell time was 113 (IQR = 85-159) minutes. Measured in 30 min epochs, increasing dwell time was not associated with in-hospital mortality, 24-h mortality, cause of death and initial pH, but was associated with lower 24-h SOFA score (p = 0.01) and lower initial lactate (p = 0.03). Rearrest during transport was rare (n = 29, 5%). Dwell time was associated with lower probability of rearrest during transport (OR = 0.847, (95% CI 0.68-1.01), p = 0.07). CONCLUSIONS: Dwell time was not associated with in-hospital mortality. Rapid transport may be associated with risk of rearrest. Prospective data are needed to clarify optimal patient stabilization and transport strategies.

Evaluation of transport-related outcomes for neonatal transport teams with and without physicians.

OBJECTIVE: The aim of this study was to evaluate if the presence of a physician in the neonatal transport team (NTT) affects transport-related outcomes and procedural success. DESIGN: Retrospective cohort study with propensity score matching. SETTING: Canadian national study. PATIENTS: Neonatal transports from nontertiary centres between January 2014 and December 2017. INTERVENTIONS: Comparison of transports conducted by NTTs with physicians (MD Group) and without physicians (noMD Group). MAIN OUTCOME MEASURES: The primary outcome was the change in patient acuity as measured by the transport risk index of physiologic severity (TRIPS) score. Secondary outcomes included mortality within 24 hours of NICU admission, clinical complications during transport, procedural success, and stabilization time. RESULTS: Among 9,703 eligible cases, 899 neonatal transports attended by NTTs with physicians were compared to 899 neonatal transports without physicians using propensity score matching. No differences were seen in the improvement of TRIPS score or mortality ≤24 hours of NICU admission. The MD Group had more clinical complications (7.7% versus 5.0%, P=0.02). No differences were seen in success rates of invasive procedures. The MD Group had shorter stabilization times. In multivariable analysis, the MD Group was not a significant predictor for the improvement in TRIPS score after adjustment for covariates. CONCLUSIONS: Neonatal transports conducted by teams including physicians compared to teams without physicians, did not have higher improvement in TRIPS scores and had similar success rates for procedures. These results provide insights for the planning of the structure and training of specialized interfacility neonatal transport programs.

Interprofessional two-man team approach for interhospital transport of ARDS-patients under extracorporeal membrane oxygenation: a 10 years retrospective observational cohort study.

BACKGROUND: Extra Corporeal Membrane Oxygenation (ECMO) has become an accepted treatment option for severely ill patients. Due to a limited availability of ECMO support therapy, patients must often be transported to a specialised centre before or after cannulation. According to the ELSO guidelines, an ECMO specialist should be present for such interventions. Here we describe the safety and efficacy of a reduced team approach involving one anaesthesiologist, experienced in specialised intensive care medicine, and a specialised critical care nurse. METHODS: This study is a 10 years retrospective, single institution analysis of all data collected between January 2007 and December 2016 from the medical records at the University Hospital Bonn, Germany. RESULTS: The Bonner mobile ECMO team was deployed in 170 cases for on-site evaluation for ECMO support therapy. 4 (2.4%) patients died prior to arrival or during the implementation of ECMO support. Of the remaining 166 patients, 126 were cannulated at the referring site, 40 were transported without ECMO. Of those, 21 were subsequently cannulated out our centre. 19 patients never received ECMO treatment. The primary indication for ECMO treatment was ARDS (159/166 patients). Veno-venous ECMO was initiated in 137, whilst 10 patients received veno-arterial ECMO treatment. Mean transportation time was 75 ± 36 min, and mean transport distance was 56 ± 57 km. In total, 26 complications were observed, three being directly transport-related. The overall survival was 55%. CONCLUSIONS: Initiation of extracorporeal membrane oxygenation and subsequent transport can be safely and efficiently performed by a two-man team with good outcome.

Intubation in Pediatric/Neonatal Critical Care Transport: National Performance.

BACKGROUND: There are nearly 200,000 US infants/children transported annually for specialty care and there are no published best practices in transport intubation. OBJECTIVE: Respiratory interventions are a priority in pediatric and neonatal critical care transport (PNCCT). A recent Delphi study identified intubation performance as an important PNCCT quality metric, though data are insufficient. The objective of the study is to determine multi-center rates of first attempt intubation success in pediatric/neonatal transport and identify practice processes associated with higher performing centers. METHODS: Retrospective chart review where data was collected from the 9 participating centers over a 6-month period from January-June 2013. Data describing intubation training and practices were gathered using SurveyMonkey® (Palo Alto, CA). Data were tabulated in Microsoft Excel (Redmond, WA) and analyzed using descriptive statistics. Through the determination of 1(st) intubation success rate across multiple pediatric/neonatal critical care transport programs, we hypothesized that the features of higher and lower performing centers can be identified to inform practice. RESULTS: 9 of 14 invited institutions participated. The median (IQR) 6-month transport volume for neonates(neo) was 289(35-646) and pediatric (ped) 510(122-831). On average, 7%(+/-3.0) of neo and 1.6%(+/-0.7) of ped transport patients required intubation. Individual centers had their initial success rate calculated and a 95% confidence interval was determined for those centers satisfying the np > 5 and n(1-p) > 5 sample size requirement for normality assumption of proportions. Since the overall success rate was 64%, it was determined that n = 14 initial intubation attempts would be the minimum number needed per center in order to fulfill the sample size requirement for normality assumption. Centers whose 95% confidence interval did not contain the initial overall success rate were identified. CONCLUSION: This represents the first multi-center neo/ped intubation dataset in PNCCT. First attempt intubation success lags behind reported anesthesia intubation rates but parallels pediatric emergency department intubation success rates. Training and operational processes are variable in PNCCT, though top performing teams require live-patient intubation success to achieve initial intubation competency.

The interfacility transport of critically ill newborns.

The practice of paediatric/neonatal interfacility transport continues to expand. Transport teams have evolved into mobile intensive care units capable of delivering state-of-the-art critical care during paediatric and neonatal transport. While outcomes are best for high-risk infants born in a tertiary care setting, high-risk mothers often cannot be safely transferred. Their newborns may then have to be transported to a higher level of care following birth. The present statement reviews issues relating to transport of the critically ill newborn population, including personnel, team competencies, skills, equipment, systems and processes. Six recommendations for improving interfacility transport of critically ill newborns are highlighted, emphasizing the importance of regionalized care for newborns.

Le transport interhospitalier des nouveau-nés et des enfants continue de prendre de l'expansion. Les équipes de transport se sont transformées en unités de soins intensifs mobiles en mesure de prodiguer des soins intensifs de pointe à ces populations pendant le transport. L'évolution des nouveau-nés à haut risque est plus favorable dans un établissement de soins tertiaires, mais bien souvent, les mères à haut risque ne peuvent pas être transférées en toute sécurité. Leur nouveau-né devra peut-être être transporté vers un établissement offrant un niveau de soins plus avancé après la naissance. Le présent document de principes traite des enjeux liés au transport des nouveau-nés gravement malades, y compris le personnel, les compétences et les habiletés de l'équipe, l'équipement, les systèmes et les processus. Sont présentées six recommandations pour améliorer le transport interhospitalier des nouveau-nés gravement malades, qui font ressortir l'importance des soins régionaux pour les nouveau-nés.

Direct vs. redirected admission of critically ill children to PICU after interfacility transfer: a retrospective cohort study.

Background: Critically ill children must often be transported long distances for access to critical care resources in Canada. This study aims to describe and compare characteristics and outcomes in patients presenting in the community and requiring inter-facility transport and admission to a Pediatric Intensive Care Unit (PICU). Methods: This is a retrospective cohort study of children admitted to the ICU at the Hospital for Sick Children from 2016 to 2019 after inter-facility transport. Characteristics and outcomes were compared between children admitted to the PICU within 24 h from their initial critical care transport request, and children admitted after initial redirection to a non-ICU care setting, 24-72 h from request. The primary outcome was severity of illness at PICU admission. Secondary outcomes included duration of mechanical ventilation, organ dysfunction, PICU length of stay and mortality. Results: A total of 2,730 patients were admitted after inter-facility transport to either the medical/surgical or cardiac ICU within 72 h of initial critical care transport request. Of these children, 2,559 (94%) were admitted within 24 h and 171 (6%) were admitted between 24 and 72 h. Children admitted after initial redirection were younger and residing in more rural centers. Children who were initially redirected had lower severity of illness (PRISM-IV median score 3 vs. 5, p = 0.047) and lower risk of mortality. Interpretation: Initial redirection to a non-ICU care setting rather than directly admitting to the PICU did not result in increased severity of illness or mortality. This study highlights the need to better understand which factors influence disposition decision-making at the time of initial transport request. Further research should focus on the impact of transport factors on clinical outcomes after PICU admission.

Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) prior to interfacility transfer: Who might benefit in a statewide trauma system?

BACKGROUND: Rural trauma patients are often seen at lower-level trauma centers before transfer and have higher mortality than those seen initially at a Level 1 Trauma Center. This study aims to describe the potential for Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) to bridge this mortality gap. METHODS: We queried the Arizona Trauma Registry between 2014 and 2017 for hypotensive patients who were later transported to a level 1 center. REBOA candidates were identified as those with injuries consistent with major infra-diaphragmatic torso hemorrhage as the likely cause of death. RESULTS: Of 17,868 interfacility transfers during the study period, 333 met inclusion criteria and had sufficient data for evaluation. 26 of the 333 patients were identified as REBOA candidates. CONCLUSIONS: Our study suggests that REBOA may be an effective means to extend survivability to those severely injured trauma patients needing interfacility transfer to a higher level of care.

A 12-month retrospective descriptive analysis of a single helicopter emergency medical service operator in four South African provinces.

Introduction: Helicopter Emergency Medical Services (HEMS) is integrated into modern emergency medical services because of its suggested mortality benefit in certain patient populations, it is an expensive resource and appropriate use/feasibility in low- to middle income countries (LMIC) is highly debated. To maximise benefit, correct patient selection in HEMS is paramount. To achieve this, current practices first need to be described. The study aims to describe a population of patients utilising HEMS in South Africa, in terms of flight data, patient demographics, provisional diagnosis, as well as clinical characteristics and interventions. Methods: A retrospective flight- and patient-chart review were conducted, extracting clinical and mission data of a single aeromedical operator in South Africa, over a 12-month period (July 2017 - June 2018) in Gauteng, Free State, Mpumalanga and North-West provinces. Results: A total of 916 cases were included (203 primary cases, 713 interfacility transport (IFT) cases). Most patients transported were male (n=548, 59.8%) and suffered blunt trauma (n=379, 41.4%). Medical pathology (n=247, 27%) and neonatal transfers (n=184, 20.1%) follows. Flights occurred mainly in daylight hours (n=729, 79.6%) with median mission times of 1-hour 53 minutes (primary missions), and 3 hours 10 minutes (IFT missions). Median on-scene times were 26 minutes (primary missions) and 55 minutes (IFT missions). Almost half were transported with an endotracheal tube (n=428, 46.7%), with a large number receiving no respiratory support (n=414, 45.2%). No patients received fibrinolysis, defibrillation, cardioversion or cardiac pacing. Intravenous fluid therapy (n=867, 94.7%) was almost universal, with common administration of sedation (n=430, 46.9%) and analgesia (n=329, 35.9%). Conclusion: Apart from the lack of universal call-out criteria and response to the high burden of trauma, HEMS seem to fulfil an important critical care transport role. It seems that cardiac pathologies are under-represented in this study and might have an important implication for crew training requirements.

Neonatal transport services, a cross-sectional study.

Objective: To understand the process and challenges facing neonatal transport in Canada and to delineate their composition and working.Subjects and methodology: An online questionnaire was sent to all neonatal transport team directors/coordinators in Canada. The questionnaire covered different aspects of transport and was pilot tested prior to finalization. The responses were anonymous to the investigators.Results: All sixteen neonatal transport teams in Canada surveyed. Fifteen teams responded. Dedicated team as a model was adopted by 12 teams (80%). A combined Neonatal/pediatrics team, where the team could be assembled by either neonatal or pediatrics intensive care staff, adopted by two (13%). Team members were cross-trained in about quarter of the teams (four teams out of 15) with respiratory therapists and registered nurses performing each other's roles. Neonatal Resuscitation Program was mandatory for all teams that responded (15 teams) to become certified as a neonatal transport team member. Nine teams use a central dispatch phone call system.Conclusion: As the first to comprehensively describe the status of neonatal transport in Canada, our study shows that neonatal transport teams have similarities as well as differences. Regionalization and differences in referral practices, geography, provincial laws, and manpower are the main reasons why teams may have their individual variations in policies, protocols, and logistics. Our data can be utilized by health professionals and policy makers to improve neonatal transport logistics within their health care systems resulting in better outcomes of transported neonates.

Importance of specialized paediatric and neonatal transport. Current situation in Spain: Towards a more equitable and universal future.

Specialized paediatric and neonatal transport is a useful and essential resource in the interhospital transfer of these patients. It allows bringing the material and personal resources of an intensive care unit closer to the regional hospitals where the patient can be found. The benefits of these teams are very well demonstrated in the literature. These units should be part of the emergency systems, while it would be recommended that they be staff integrated in the tertiary hospitals, in order to maintain the necessary skills and competencies. The team, made up of physicians, nurses and emergency medical technicians, must master both the pathophysiology of transport and that of the critical patient in this age range. A high quality of both human and care is important, so continuous training and periodic recycling will be essential to be compliant with the quality indicators in transport. Likewise, it is essential to have specific vehicles adapted to this function, which allow carrying the wide variety of necessary material, as well as the electromedicine that is required. However, in Spain this paediatric and neonatal transport model is not standardized and therefore is not homogeneous: there are different models that do not always provide adequate quality, making it necessary to implement specialized units throughout the country to guarantee sanitary transport quality to any critical child or neonate.

Interfacility ambulance transport of mental health patients.

The transportation of mental health patients between facilities by emergency medical services personnel poses a unique risk to both patients and their providers. Increasingly, common injuries are occurring and difficulties are arising during this transition in care. Proximal causes exist that could be addressed to help mitigate many of the complexities that occur during this shift in care. Patient safety, quality of care, and provider safety are all at risk if improvements are not made and problems not identified or rectified.

Standardised early warning scores in rural interfacility transfers: A pilot study into their potential as a decision-making aid.

INTRODUCTION: While 12.4% of British Columbians live rurally, only 2.0% of specialists practise rurally, making interfacility transport of high-acuity patients vital. Decision-making aids have been identified as a way to improve the interfacility transfer process. We conducted a pilot study to explore the potential of the Standardised Early Warning Score (SEWS) as a decision-making aid for staff at sending facilities. METHODS: SEWSs were calculated from a database of 418 transfers from sending facilities in rural, small and medium population centres to larger receiving facilities. The SEWSs were compared against one another over time using McNemar's and the Wilcoxon signed-ranks tests. The SEWSs were then tested for their association with six outcomes using Pearson's or Fisher's Chi-squared test and the Mann-Whitney U-test. RESULTS: While at the sending facility, both the number of SEWSs that was four or greater and the average SEWS decreased over time (P < 0.001 for both). A first SEWS of four or greater was predictive of more intervention categories during transport (P = 0.047), an adverse event during transport (P = 0.004), an adverse event within 30 min of arrival at the receiving facility (P = 0.004) and death before discharge from the receiving facility (P = 0.043) but not deterioration during transport, or the length of stay at the receiving facility. CONCLUSION: Overall, the performance of the SEWS in the context of rural interfacility transport suggests that the tool will have utility in supporting decision-making.

Introduction: Alors que 12,4 % des résidents de la Colombie-Britannique vivent en milieu rural, seuls 2,0 % des spécialistes y pratiquent, ce qui rend essentiel le transport entre établissements des patients en état grave. Des outils de prise de décision ont été désignés comme méthode pour améliorer le processus de transfert entre établissements. Dans le cadre d'une étude pilote, nous nous sommes penchés sur le potentiel du score SEWS (Standardised Early Warning Score) comme outil de prise de décision à l'intention du personnel des établissements d'origine. Méthodes: Les scores SEWS ont été calculés dans une banque de données de 418 transferts d'établissements d'origine situés dans des agglomérations rurales de petite et moyenne taille vers des établissements de réception plus importants. Les scores SEWS ont été comparés entre eux dans le temps à l'aide des tests de McNemar et Wilcoxon Signed Ranks. L'association des scores SEWS à six paramètres d'évaluation a ensuite été testée à l'aide des tests de chi carré de Pearson ou de Fisher et du test de Mann-Whitney. Résultats: À l'établissement d'origine, le nombre de scores SEWS de quatre et plus et le score SEWS moyen se sont abaissés dans le temps (p < 0,001 dans les deux cas). Un score SEWS initial de quatre et plus prédisait un plus grand nombre de catégories d'interventions durant le transport (p = 0,047), la survenue d'un événement indésirable durant le transport (p = 0,004), la survenue d'un événement indésirable dans les 30 minutes après l'arrivée à l'établissement de réception (p = 0,004), et le décès avant le congé de l'établissement de réception (p = 0,043), mais il ne prédisait pas la détérioration durant le transport ni la durée du séjour à l'établissement de réception. Conclusion: Dans l'ensemble, le rendement du score SEWS dans le contexte du transport rural entre établissements laisse croire que l'outil serait utile à la prise de décision.

Comparison of helicopter versus ground transport for the interfacility transport of isolated spinal injury.

BACKGROUND CONTEXT: The use and need of helicopter aeromedical transport systems (HEMSs) in health care today is based on the basic belief that early definitive care improves outcomes. Helicopter aeromedical transport system is perceived to be safer than ground transport (GT) for the interfacility transfer of patients who have sustained spinal injury because of the concern for deterioration of neurologic function if there is a delay in reaching a higher level of care. However, the use of HEMS is facing increasing public scrutiny because of its significantly greater cost and unique risk profile. PURPOSE: The aim of the study was to determine whether GT for interfacility transfer of patients with spinal injury resulted in less favorable clinical outcomes compared with HEMS. STUDY DESIGN/SETTING: Retrospective review of all patients transferred to a Level 1 trauma center. PATIENT SAMPLE: Patients identified from the State Trauma Registry who were initially seen at another hospital with an isolated diagnosis of injury to the spine and then transferred to a Level 1 trauma center over a 2-year period. OUTCOME MEASURES: Neurologic deterioration, disposition from the emergency department, in-hospital mortality, interfacility transfer time, hospital length of stay, nonroutine discharge, and radiographic evidence of worsening spinal injury. METHODS: Patients with International Classification of Diseases, Ninth Revision (ICD-9) codes for injury to the spine were selected and records were reviewed for demographics and injury details. All available spine radiographs were reviewed by an orthopedic surgeon blinded to clinical data and transport type. Chi-square and t tests and multivariate linear and logistic regression models were done using STATA version 10. RESULTS: A total of 274 spine injury patients were included in our analysis, 84 (31%) of whom were transported by HEMS and 190 (69%) by GT. None of the GT patients had any deterioration in neurologic examination nor any detectable alteration in the radiographic appearance of their spine injury attributable to the transportation process. Helicopter aeromedical transport system resulted in significantly less transfer time with an average time of 80 minutes compared with 112 minutes with GT (p<.001). Ultimate disposition included 175 (64%) patients discharged to home, 15 (5%) expired patients, and 84 (31%) discharged to extended care facilities. After adjusting for patient age and Injury Severity Score, the use of GT was not a significant predictor of in-hospital mortality (odds ratio, 1.4; 95% confidence interval, 0.3-5), hospital length of stay (11.2+1.3 vs. 9.5+0.8 days, p=.3), or nonroutine discharge (odds ratio, 1.1; 95% confidence interval, 0.5-2.2). CONCLUSIONS: Ground transport for interfacility transfer of patients with spinal injury appears to be safe and suitable for patients who lack other compelling reasons for HEMS. A prospective analysis of transportation mode in a larger cohort of patients is needed to verify our findings.
