Timing of Transport of Patients with COVID-19.

RATIONALE: The objective of this study was to evaluate the risk of mortality or ECMO cannulation for patients with confirmed or suspected COVID-19 transferred from sending hospitals to receiving tertiary care centers as a function of the duration of time at the sending hospital. OBJECTIVE: To determine outcomes of critically ill patients with COVID-19 who were transferred to tertiary or quarternary care medical centers. MATERIALS AND METHODS: Retrospective cohort study of critical care transports of patients to one of seven consortium tertiary care centers from March 1, 2020, through September 4, 2020. Age 14 years and older with confirmed or suspected COVID-19 transported from a sending hospital to a receiving tertiary care center by the critical care transport organization. RESULTS: Patients transported with confirmed or suspected COVID-19 to tertiary care centers had a mortality rate of 38.0%. Neither the number of days admitted, nor the number of days intubated at the sending hospital correlated with mortality (correlation coefficient 0.051 and -0.007, respectively). Similarly, neither the number of days admitted, nor number of days intubated at the sending hospital correlated with ECMO cannulation (correlation coefficient 0.008 and -0.036, respectively). CONCLUSION: It may be reasonable to transfer a critically ill COVID-19 patient to a tertiary care center even if they have been admitted at the sending hospital for several days.

Air Versus Ground Transport Times in an Urban Center.

PURPOSE: Given that the benefits of helicopter transport vary with geography and healthcare systems, we assessed transport times for rotor wing versus ground transport over a 10 year period in an urban setting. MATERIALS AND METHODS: All completed transports from 153 sending hospitals in New England from 2009 through 2018 to 8 local tertiary care centers were extracted from an administrative database. The primary outcome of interest was patient-loaded transport time for rotor wing versus ground transports. Overall, 25,483 patient transports met the inclusion criteria and were included in this study. We assessed patient-loaded transport time for all transports, and determined mean time to arrive at the scene, scene to patient time, the bedside time, and distance at which the patient-loaded transport time was faster for rotor wing than for ground transport. We also performed subgroup analyses, evaluating transport times by time of day, day of the week, and destination. RESULTS: The most common indication for transport was adult trauma, (n = 6,008, 23.6%) followed by adult cardiac (n = 4359, 17.1%), adult neuro (3729 14.6%), and adult medical (n = 3691, 14.5%). The median miles traveled for all transports was 26.0, IQR 14-38, ranging from 1 to 264 miles. The median patient-loaded transport time was 27 min (IQR 15-40) for all transports. Nearly all time intervals were shorter for rotor wing versus ground transports, and patient-loaded transport time was significantly shorter at 15 minutes compared to 38 minutes (IQR 12-22 vs 28-33, p < 0.001). There was no distance at which the patient-loaded transport time was faster for ground transport than for rotor wing. CONCLUSIONS: In over 25,000 transports over 10 years, in a compact metropolitan area with relatively short transport distances and times, the use of the helicopter was associated with substantial time savings.

Ventilator Management in Metformin-Associated Lactic Acidosis: A Case Report.

The initiation of mechanical ventilation in the setting of profound metabolic acidosis can be a particular challenge in the transport environment. The classic teaching is that patients with severe acidemia should not be intubated, if possible, because they are often able to better maintain their own compensatory minute ventilation compared with clinician management with the mechanical ventilator. In this case, a patient had profound metformin-associated lactic acidosis with a pH of 6.51 and required intubation for deteriorating mental status with an inability to protect her airway. Maintaining adequate minute ventilation can be directly in conflict with the evidence-based approach of low tidal volume ventilation for all patients. When patients have profound metabolic acidosis without evidence of acute respiratory distress syndrome, increasing the tidal volume slightly to allow for more efficient respiration can be an effective strategy to maintain acid-base status.

Interfacility Transport of Critically Ill Patients.

OBJECTIVES: To assess recent advances in interfacility critical care transport. DATA SOURCES: PubMed English language publications plus chapters and professional organization publications. STUDY SELECTION: Manuscripts including practice manuals and standard (1990-2021) focused on interfacility transport of critically ill patients. DATA EXTRACTION: Review of society guidelines, legislative requirements, objective measures of outcomes, and transport practice standards occurred in work groups assessing definitions and foundations of interfacility transport, transport team composition, and transport specific considerations. Qualitative analysis was performed to characterize current science regarding interfacility transport. DATA SYNTHESIS: The Task Force conducted an integrative review of 496 manuscripts combined with 120 from the authors' collections including nonpeer reviewed publications. After title and abstract screening, 40 underwent full-text review, of which 21 remained for qualitative synthesis. CONCLUSIONS: Since 2004, there have been numerous advances in critical care interfacility transport. Clinical deterioration may be mitigated by appropriate patient selection, pretransport optimization, and transport by a well-resourced team and vehicle. There remains a dearth of high-quality controlled studies, but notable advances in monitoring, en route management, transport modality (air vs ground), as well as team composition and training serve as foundations for future inquiry. Guidance from professional organizations remains uncoupled from enforceable regulations, impeding standardization of transport program quality assessment and verification.

Operational Policies and Procedures for Critical Care Transport During a Respiratory Pandemic.

The severe acute respiratory syndrome coronavirus 2 pandemic of 2020 to 2021 created unprecedented challenges for health care organizations, including those in the critical care transport sector. Critical care transport services had to rapidly adjust to changing patient demographics, distribution of diagnoses, and transport utilization stratagem. To evolve with the pandemic, organizations developed new protocols and guidelines in rapid succession. The growth bore out of a need to cater to this new patient population and their safety as well as the safety of the crewmembers from severe acute respiratory syndrome coronavirus 2. The critical changes to operations involved adaptability, efficient communication, continual reassessment, and implementation of novel approaches. Although these lessons learned were specific to coronavirus disease 2019, many processes will apply to future respiratory epidemics and pandemics. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) pandemic of 2020 to 2021 created unprecedented challenges for health care organizations, including critical care transport (CCT) organizations. The changes were numerous, including a change in the patient population, with a rapid decrease in trauma and pediatrics to a preponderance of adult patients with acute hypoxemic respiratory failure. CCT teams were called on to transport these patients at potential risk to themselves, especially early in 2020, before the effectiveness of personal protective equipment (PPE) was determined. Even seemingly simple tasks, such as defining a person under investigation (PUI) for coronavirus disease 2019 (COVID-19), varied from institution to institution, putting transport organizations in the middle of conflicts. Agility has always been an essential part of any CCT organization because clinicians and managers must adapt to an unpredictable environment. However, the frequency and speed of changes occurring during the COVID-19 pandemic were unprecedented. This report offers our best practices based on our experience and the available data. Although these procedures were developed for the COVID-19 pandemic, they will logically apply to future respiratory outbreaks and illuminate helpful changes for otherwise quotidian operations.

Critical Care Transport of Patients With COVID-19.

PURPOSE: Critical care transport is associated with a high rate of adverse events, and the risks and outcomes of transporting critically ill patients during the COVID-19 pandemic have not been previously described. MATERIALS AND METHODS: We performed a retrospective review of transports of subjects with suspected or confirmed COVID-19 from sending hospitals to tertiary care hospitals in Boston. Follow-up data were obtained for patients transported between March 1st and April 20th, 2020. RESULTS: Of 254 charts identified, 250 patients were transported. Nine patients (3.5%) had cardiac arrest prior to transport. Twenty-nine (11.6%) had hypotension, 22 (8.8%) had a critical desaturation, and 4 (1.6%) had both en route. Hospital follow-up data were available for 189 patients. Of those intubated during their hospitalization, 44 (25.0%) had died, 59 (33.5%) had been extubated, and 13 (17.6%) had been discharged alive. For the subgroup with prior cardiac arrest, follow-up data available for 6. Of these 6, 2 died and 4 (66.7%) have been discharged alive. CONCLUSIONS: Few patients with COVID-19 had an adverse event in transport. The in-hospital mortality rate was 25%, with a 33.5% extubation rate. Patients resuscitated from cardiac arrest prior to transport had a 66.7% discharge rate among those transported to consortium hospitals.

Transport of a Nonintubated Prone Patient with Severe Hypoxemic Respiratory Failure Due to COVID-19.

With the COVID-19 pandemic, healthcare systems have been facing an unprecedented, large-scale respiratory disaster. Prone positioning improves mortality in severe hypoxemic respiratory failure, including COVID-19. While this is effective for intubated patients with moderate-to-severe ARDS, it has also been shown to be beneficial for non-intubated patients. Critical care transport (CCT) has become an essential component of combating COVID-19, frequently transporting patients to receive advanced respiratory therapies and distribute patients in concert with available resources. With increasing awake proning, CCT teams may encounter patients supported in the prone position. Historically, transporting in the prone position has not been embraced due to substantial risks of desaturation during transport. In this case report, we describe the first known report of transporting a non-intubated, critically ill COVID-19 patient in the prone position.

The Effect of Lights and Sirens on Critical Care Transport Time.

BACKGROUND: In the prehospital setting, the use of ambulance lights and sirens (L&S) has been found to result in minor decreases in transport times, but has not been studied in interfacility transportation. OBJECTIVE: The objective of this study was to evaluate the indications for L&S and the impact of L&S on transport times in interfacility critical care transport. METHODS: We performed a retrospective analysis using administrative data from a large, urban critical care transportation organization. The indications for L&S were assessed and the transport times with and without L&S were compared using distance matching for common transport routes. Median times were compared for temporal subgroups. RESULTS: L&S were used in 7.3% of transports and were most strongly associated with transport directly to the operating room (odds ratio 15.8; 95% confidence interval 6.32-39.50; p < 0.001). The timing of the transport was not associated with L&S use. For all transports, there was a significant decrease in the transport time using L&S, with a median of 8 min saved, corresponding to 19.5% of the overall transportation time without L&S (33 vs. 41 min; p < 0.001). The reduction in transport times was consistent across all temporal subgroups, with a greater time reduction during rush hour transports. CONCLUSIONS: The use of L&S during interfacility critical care transport was associated with a statistically significant time reduction in this urban, single-system retrospective analysis. Although the use of L&S was not associated with rush-hour transports, the greatest time reduction was associated with L&S transport during these hours.

Clinical Policies and Procedures for Critical Care Transport during a Respiratory Pandemic.

The severe acute respiratory syndrome coronavirus disease-2 (SARS-CoV-2) pandemic of 2020-2021 created unprecedented challenges for clinicians in critical care transport (CCT). These CCT services had to rapidly adjust their clinical approaches to evolving patient demographics, a preponderance of respiratory failure, and transport utilization stratagem. Organizations had to develop and implement new protocols and guidelines in rapid succession, often without the education and training that would have been involved pre-coronavirus disease 2019 (COVID-19). These changes were complicated by the need to protect crew members as well as to optimize patient care. Clinical initiatives included developing an awake proning transport protocol and a protocol to transport intubated proned patients. One service developed a protocol for helmet ventilation to minimize aerosolization risks for patients on noninvasive positive pressure ventilation (NIPPV). While these clinical protocols were developed specifically for COVID-19, the growth in practice will enhance the care of patients with other causes of respiratory failure. Additionally, these processes will apply to future respiratory epidemics and pandemics.

ECMO Transport without Physicians or Additional Clinicians.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) has accelerated rapidly for patients in severe cardiac or respiratory failure. As a result, ECMO networks are being developed across the world using a "hub and spoke" model. Current guidelines call for all patients transported on ECMO to be accompanied by a physician during transport. However, as ECMO centers and networks grow, the increasing number of transports will be limited by this mandate. OBJECTIVES: The aim of this study was to compare rates of adverse events occurring during transport of ECMO patients with and without an additional clinician, defined as a physician, nurse practitioner (NP), or physician assistant (PA). METHODS: This is a retrospective cohort study of all adults transported while cannulated on ECMO from 2011-2018 via ground and air between 21 hospitals in the northeastern United States, comparing transports with and without additional clinicians. The primary outcome was the rate of major adverse events, and the secondary outcome was minor adverse events. RESULTS: Over the seven-year study period, 93 patients on ECMO were transported. Twenty-three transports (24.7%) were accompanied by a physician or other additional clinician. Major adverse events occurred in 21.5% of all transports. There was no difference in the total rate of major adverse events between accompanied and unaccompanied transports (P = .91). Multivariate analysis did not demonstrate any parameter as being predictive of major adverse events. CONCLUSIONS: In a retrospective cohort study of transports of ECMO patients, there was no association between the overall rate of major adverse events in transport and the accompaniment of an additional clinician. No variables were associated with major adverse events in either cohort.

Management of suspected myocarditis during critical-care transport.

Myocarditis and malignant dysrhythmias are unusual presentations in pediatric patients. We report a series of 4 patients with myocarditis and arrhythmia who presented to community emergency departments and were transported to a pediatric tertiary-care center. Three of the patients required extracorporeal life support. We discuss considerations for stabilization and transport: airway and ventilation, hemodynamic support, induction and sedation medication choices, transport decisions, and the traits of an ideal receiving center.

Inhaled Epoprostenol to Facilitate Safe Transport in Legionnaires' Disease.

Hypoxemic patients often desaturate further with movement and transport. While inhaled epoprostenol does not improve mortality, improving oxygenation allows for transport of severely hypoxemic patients to tertiary care centers with a related improvement in mortality rates. Extracorporeal membrane oxygenation (ECMO) use is increasing in frequency for patients with refractory hypoxemia, and with increasing regionalization of care, safe transport of hypoxemic patients only becomes more important. In this series, four cases are presented of young patients with severe hypoxemic respiratory failure from Legionnaires' disease transported on inhaled epoprostenol to ECMO centers for consideration of cannulation. With continued climate changes, Legionella and other pathogens are likely to be a continued threat. As such, optimizing oxygenation to allow for transport should continue to be a priority for critical care transport (CCT) services.

Feasibility and Safety of Prone Position Transport for Severe Hypoxemic Respiratory Failure Due to Coronavirus Disease 2019.

OBJECTIVES: To assess the safety and feasibility of a new protocol for interhospital critical care transport of mechanically ventilated patients in the prone position during the coronavirus disease 2019 pandemic by nurse and paramedic critical care transport teams. DESIGN: Retrospective observational study. SETTING: Single critical care transport agency serving multiple centers in the greater Boston area. PATIENTS: All transports of intubated patients in the prone position with severe hypoxemic respiratory failure secondary to coronavirus disease 2019. INTERVENTIONS: Records were reviewed for patients transported in the prone position. Major adverse events in transport, defined as severe hypoxemia (oxygen saturation < 80% or an absolute decrease in oxygen saturation > 10%), hypotension (mean arterial pressure < 65 mm Hg) not responsive to vasopressors or inotropes, endotracheal tube or vascular catheter dislodgement, and cardiac arrest, were recorded. MEASUREMENTS AND MAIN RESULTS: A total of 25 patients were transported in prone position. The mean Pao2:Fio2 ratio in the group was 101.3 mm Hg, and 76% (n = 19) were on vasopressors. Fourteen patients (56%) had hypotension with at least one episode of mean arterial pressure less than 65 mm Hg en route, and seven (28%) had an episode of oxygen desaturation less than 88%. Only one major adverse event of severe hypoxemia (oxygen saturation < 80%) was noted. CONCLUSIONS: Critical care transport of severe hypoxemic respiratory failure patients with coronavirus disease 2019 in the prone position is safe when performed by a dedicated team of critical care nurse and paramedics with an established protocol.

Factors associated with unoffered trauma analgesia in critical care transport.

OBJECTIVE: Pain relief is a key out-of-hospital patient care outcome measure, yet many trauma patients do not receive prompt analgesia. Although specialty critical care transport (CCT) teams provide analgesia frequently, successfully, and safely, there is still a population of CCT patients to whom analgesia is not offered. We report the factors associated with non-administration of analgesia and with analgesic effect in trauma patients cared for by CCT teams. METHODS: This is a retrospective review of consecutive transport records for nonintubated trauma patients with self-reported pain during specialty CCT care. Patient demographics, CCT interventions, clinical traits, and pain self-reports are measured. Means comparisons are made with a univariate analysis of variance, and odds ratios (ORs) with 95% confidence intervals (CIs) are reported for between-group comparisons. RESULTS: Of the 209 enrolled patients, 169 (80.9%; 95% CI, 75.6%-86.2%) were treated (147 received analgesia and 22 offered analgesia but refused). In patients with pain scale documentation (n=145), self-reported pain on a scale from 0 to 10 decreased from 6.8+/-2.8 to 3.3+/-2.4 (P

An overview of Medicare reimbursement regulations for advanced practice nurses.

The federal government spends nearly 15% of the budget on Medicare services annually, and advanced practice nurses are eligible for reimbursement from that pool. The regulations governing reimbursement are complex because of the social, political, and financial pressures involved in their development. Although economic viability and due diligence considerations make it incumbent on advanced practice nurses to understand the rules, the profession, as a whole, has knowledge deficits in this area. The essentials of regulatory development and structure are reviewed and considerations for optimizing reimbursement are described.
