9. Air and Surface Patient Transport

CHAPTER 9. Air and Surface Patient Transport

Reneé Semonin Holleran



Patient transport is an integral part of all emergency departments (EDs). Whether a patient must be transferred to another care facility, moved from the ED for diagnostic testing, or transported within the hospital for admission, patients will be moved. Transport nursing has evolved into a specialty that involves detailed education and training. 13 Emergency nurses are generally involved with patient preparation and stabilization before transport. This requires that the emergency nurse be familiar with indications for transport, how the practice of nursing and medicine differ in the transport environment, preparation for transfer and transport, how transport can affect the patient, and the legal issues related to patient transport.

Transport teams are staffed with a variety of personnel, including nurses, physicians, paramedics, respiratory therapists, and emergency medical technicians (EMTs). Patient transport levels can vary from basic life support (BLS) to critical care. The condition and needs of the patient must dictate the type of team needed.

Transport vehicles include modular and van type of ground ambulances, fixed-wing aircraft, and helicopters (Figure 9-1). The condition of the patient, the timely need for further care, the location of the patient, the weather, and availability of specific transport services may influence the type of vehicle used to transport the patient.

The overriding concept of any patient transport should always be safety. This includes patient safety, transport team safety, and the safety of anyone who interacts with the transport team and the vehicle used.

The quality and competency of the transport team, the vehicles, the equipment, and the training of the personnel should always be considered when choosing a transport team. The Commission on Accreditation of Medical Transport Systems (CAMTS) (http://www.camts.org) accreditation provides support that the transport program has met a set of standards that ensures the patient will receive organized, safe, and expert care before and during the transport process.


HISTORICAL PERSPECTIVE


Transferring patients from one location to another is not a new concept, and nurses have played a role in many of the historical landmarks related to transport. Florence Nightingale assisted in the transport of injured soldiers during the Crimean War. 8 Throughout the ages, soldiers on the battlefield have been transported in all types of moving conveyances. Dominique Larrey, Napoleon’s private physician, developed an organized system to triage and transport injured soldiers from the battlefield in carts.


The Korean War, Vietnam conflict, and the wars in the Middle East have demonstrated the effectiveness of helicopter transport in the care of the injured from the battlefield. The first hospital-based helicopter programs began in the early 1970s in Colorado and California. Today there are over 270 civilian-based helicopters transporting patients all over the United States and the world including Europe, Africa, Australia, and New Zealand.

During the 1960s and 1970s, Congress enacted numerous pieces of legislation addressing emergency medical care and transport. The Emergency Medical Treatment and Active Labor Act (EMTALA) was established to clarify guidelines for transfer and transport of patients. The discussion about legal regulations related to emergency nursing practice and patient transport is in Chapter 3.


TYPES OF TRANSPORT


Patient transport occurs in two distinct environments: on the surface by ambulance or in the air by a rotor-wing vehicle (helicopter) or fixed-wing vehicle (airplane). Air and surface transport have both advantages and disadvantages; therefore an informed decision to use air or surface transport must be made on the basis of many factors, such as patient condition, out-of-hospital time, weather, terrain, work space, equipment, personnel, and proximity of a landing site.


Surface Transport


Surface transport is most often accomplished using a modular type of vehicle (Figure 9-2). Patient access is generally easier in most surface vehicles. These vehicles can also accommodate larger pieces of equipment such as isolettes, ventilators, and intraaortic balloon pumps. The level of care during transport varies with the education and training of the transport personnel, from BLS to critical care transport. There are also critical care transport teams and vehicles available in many parts of the United States that provide transport of critically ill and injured patients who require complex physiologic support. In choosing a transport vehicle, the referring center must remember that legally the quality and level of care cannot diminish during the transport. In addition, the sending/transferring physician maintains accountability for the level of care provided during the transfer of the patient.

Adverse weather conditions influence the transport decision. When roads are impassable, air transport is usually the only alternative. When weather has grounded air transport vehicles, surface transport is the only option. Another important transport consideration is transit time. For many critically ill or injured patients the shorter the out-of-hospital time, the better the patient’s chance for survival. Finally, choice of a transport vehicle depends on needs of the community. Some isolated rural areas have only one surface ambulance for a largely scattered population base. If this vehicle is taken out of service for an interfacility transport, the community is left without coverage for the duration of the transport.


Air Transport


Air transport should not be chosen indiscriminately. In many parts of the United States, air medical transport should be considered an adjunct to, and not a replacement for, surface-based services. However, in rural and frontier areas of the country, it may be the most cost-effective and safest way to transport patients. Research remains inconclusive as to the advantage of rotor-wing transport over surface transport. Some of the reasons that a helicopter may be chosen over a surface vehicle include time or length of transport and the critical care capabilities of the medical crew. However, there are critical care teams available in some areas of the country that only perform ground transport. 14

Rotor-wing aircraft provide rapid point-to-point transport. Helicopters can reach most areas, bypassing difficult terrain. Landing zones can be made at or near the patient to prevent lengthy surface transport time. Most helicopters operate within 150 miles of their base station to allow routine flights without refueling. One disadvantage of helicopters is that their use depends on minimum weather conditions, without which flights can be delayed or canceled. Helicopter cabin size and configuration can restrict access to the patient and limit in-flight interventions. Weight limitations restrict the number of passengers and amount of equipment on board. When transferring by rotor-wing vehicles, comprehensive patient stabilization may be required before transport.

The advantage of fixed-wing transport is the ability to travel long distances. Care is provided in a pressurized cabin with sophisticated on-board medical equipment. Many fixed-wing aircraft can transport multiple patients. All-weather navigational equipment allows for transfer during inclement weather. Fixed-wing transport requires suitable airfields to ensure safety of the crew and patient. Accessibility to such fields may be a problem in isolated areas.


TRANSPORT PROCESS


Patient transport today requires an organized process. There are multiple elements to the transport process, and in order to make it smooth and time-effective these components should be put in place before a transport is required.

This process continues to vary throughout the United States and throughout the world. Multiple organizations, including prehospital, emergency, and critical specialties, have published recommendations on how to perform patient transport. However, the National Guideline Clearinghouse11 has published guidelines for the interhospital and intrahospital transport of critically ill patients. Using evidence-based research, these guidelines provide information about pretransport coordination and communication, transport personnel, monitoring during transport, and documentation.


Prehospital Transport


In most parts of the country, prehospital transport can be initiated by laypersons through the 9-1-1 and enhanced 9-1-1 emergency access numbers. Sophisticated prehospital emergency medical services (EMS) provide patient transport to the nearest appropriate medical care facility. Emergency nurses possess the knowledge to function as prehospital care providers, but their ability to function in this role varies from state to state. Surface transport can also be initiated for interfacility transport of patients with medical needs that exceed the capabilities of the local hospital.

The use of helicopters in the prehospital transport environment (scene responses) may be governed by local EMS or other state agencies. The National Association of EMS Physicians15 and the American College of Emergency Physicians2 have proposed guidelines for the use of air medical transport from the field. These are summarized in Box 9-1.

Interfacility Transfers


Every emergency nurse has the potential to become involved with organizing and implementing an interfacility transfer. Effective organization includes assessment and understanding of the referring facility’s capabilities and an in-depth knowledge of available EMS and transport systems. Implementation of the transport process is expedited if this knowledge is part of a proactive referral strategy developed well in advance.

Emergency nurses must be aware of the potential role they may be asked to play in patient transport. Today there are few places in the United States where a transport team may not be available. If an emergency nurse or any other nurse is asked to accompany a transport team on a patient transfer, he or she must be aware of the type of equipment accessible in the transport vehicle, how to operate it, the skills level of the team that is accompanying the patient. The safety of the nurse is also an important component of the transfer process. Appropriate restraint devices should be present in the transport vehicle. A safety briefing should also be given and the nurse provided with any other information that would assist in providing a safe transport.

Development of transfer strategies begins with objective assessment of the referring institution’s personnel and facilities. Qualifications and availability of physicians and nurses to care for all patients who come to the ED must be examined. Specific areas that should be considered include the critical care unit; the operating suites; and pediatric, obstetric, neonatal, and psychiatric units. Ability to perform advanced diagnostic testing and provide adequate blood and blood products must also be analyzed. All these factors influence the level of care available to sick or injured patients.

Understanding the capabilities of the receiving institution is an inherent responsibility of the referring institution. Trauma patients are best cared for in facilities designated by the American College of Surgeons Committee on Trauma as trauma centers. High-risk neonates benefit from care in a neonatal intensive care unit. Other areas of advanced specialized care include stroke centers, burn centers, limb replantation centers, pediatric centers, high-risk obstetric centers, open-heart centers, and hyperbaric centers.

Communication


There should be nurse-to-nurse communication from the referring facility to the receiving facility. If this cannot be accomplished, a member of the transport team may provide a report. A copy of the medical record and relevant laboratory and radiographic studies must accompany the patient. Technology in some areas of the country may allow these studies to be transmitted ahead of the patient. Preparation of documents should never delay patient transport. If time is of the essence, critical information will need to be communicated verbally. Policies and procedures should exist within transport programs that assist in directing how communication will be initiated and followed up between the referring and receiving facilities. Health Insurance Portability and Accountability Act (HIPAA) guidelines must be followed when communicating protected health care information.


Transport Team Members


The team members that accompany a patient will be determined by the condition and level of care that the patient requires. CAMTS standards7 outline the required team members for BLS, advanced life support (ALS), and critical care transport. Two team members at a minimum along with the vehicle operator should accompany the patient. For critical care transports CAMTS recommends that one member of the team be an appropriately educated and competent registered nurse. Other members of the team may include a physician, paramedic, respiratory therapist, or another registered nurse. All should be competent in the transport process.

If a physician is not part of the transport team, the team should operate using protocols and have the ability to communicate with a command physician to provide medical direction if there is a variation from protocol or a problem develops.

Transport team configurations are many and varied. Transport nursing has developed into a subspecialty of emergency and critical care nursing. Transport nurses now go through specific and rigorous training before joining a transport team. The Air Surface Transport Nurses Association (ASTNA), formerly the National Flight Nurses Association, has developed a flight and ground transport nursing core curriculum to provide standardized education and training in such areas as flight physiology, stabilization, communications, and medicolegal issues. 6 Initial training should include classroom and clinical experiences, including advanced airway management, invasive skills, and critical and emergency care. Preceptor programs are frequently used to allow the new transport nurse exposure to the transport environment. Recurrent training is needed to maintain skills, update information regarding current therapies, and review policies and procedures. Monthly transport reviews provide performance improvement opportunities and promote shared learning experiences among staff. Continuous performance improvement should be one of the guiding principles of transport nursing practice.


Some states require additional credentials for nurses who work in the prehospital environment. This may include the need to become an EMT or an EMT-paramedic (EMT-P). It is the professional responsibility of transport nurses to be aware of the regulations that may dictate their practice within the states in which they perform transports.


Transport team members work under a unique set of circumstances. Interactions with the patient are short and often rushed. The patients who are transported are at an increased risk for further injury or death because of circumstances necessitating transport. Transport personnel must remember that they are often the only contact the family has with the receiving hospital. The team should try to make contact with the family, explaining interventions and other procedures that may be needed for transport. Maintaining contact and follow-up with referring personnel also provides the transport team with opportunities to communicate patient status. Fostering collegial relationships instills a sense of commitment and pride in the transport nurse role, as well as providing an opportunity to improve patient care.


Transport Equipment


State regulations generally dictate what equipment should be on both surface and air transport vehicles. However, there are some general guidelines recommended by CAMTS, the National Association of Emergency Medical Services Physicians (NAEMSP), the American College of Emergency Physicians (ACEP), the American Academy of Pediatrics, and the American College of Surgeons for equipment that should be available for transport. 2.7.15. and 17.

The mission, size of the transport vehicle, and patient clinical condition are factors that influence the equipment carried during transport. General equipment should include equipment used to monitor and manage airway, oxygenation, and vital signs, as well as devices necessary for resuscitation and stabilization such as a defibrillator and external pacemaker. Medications for advanced life support and pain management should also be included.

All equipment should be routinely evaluated to see if it functions properly. Annual preventive maintenance checks should be dated and visible for team members to view. Medications must be checked for expiration and stored at the appropriate temperature. Policies and procedures must be in place to ensure that team members receive the proper education and training as to how to use the equipment. There should be an established method of removing and replacing malfunctioning equipment. Documentation of this process is imperative.

As technology continues to advance, many pieces of equipment are becoming multifunctional and longer lasting. In addition, advanced procedures such as extracorporal perfusion can now be continued during transport. Box 9-3 contains a sum-mary of some of the equipment that may be used during transport.
