ACEP Survey
The most recent data available from ACEP comes from a 1999 work force study. Of approximately 900 responding hospitals, a third indicated that they utilize physician assistants in their EDs. The results were published in the July 2002 Annals of Emergency Medicine, Vol. 40, No.1. (

Question 8 What determines how PAs are utilized in the ED?
Answer 8 Four parameters determine how PAs are utilized in the ED: (1) The first is PA education and training. A new graduate may have a somewhat basic scope of practice, which expands as supervised practice and additional training in the clinical setting increases the PA?s experience and skill level. (2) The second determinant of PA utilization is state law. In general, state laws define the PA?s scope of practice as those tasks a PA has been trained to do that are delegated and supervised by the physician. However, some state laws have specific restrictions or requirements. (3) The third determinant of PA utilization is the hospital?s bylaws or policy regarding PA practice. (4) Last, in EDs, PAs work as members of physician-directed teams and derive their scope of practice from physician?s delegation. Supervising physicians determine PA utilization through their decisions on delegation and supervision.
Question 9 What are the practice models for PA use in the ED?
Answer 9 PAs are utilized in all areas of the ED and in all settings, from being the solo provider in a rural ED to providing patient care at a Level I Trauma Center. In each situation as part of the physician/PA team. When staffing the ED, a PA typically sees the same patient acuity mix as the physicians they work as a part of a physician-PA team
Question 10 Are PAs cost effective in the ED?
Answer 10 Utilizing PAs in the ED has proven to be both cost effective and efficient. PAs provide similar, and in most cases identical, medical services that are being provided by their supervising physician, but at a much lower cost. By adding a PA program to the ED, more patients can be seen faster, reducing patients waiting times and improving patient satisfaction. PAs can be utilized to see lower acuity patients and those patients most likely to be discharged home from the ED, giving the physician more time to care for critical patients.
Question 11 How can I recruit a PA? Should I recruit a new graduate or an experienced PA?
Answer 11 An emergency department should consider its needs when recruiting physician assistants. Providing rotations for PA students in an ED is an excellent way to recruit new graduates; the physicians have a chance to work with the PA student before making a hiring decision. Any organization hiring a new graduate should be mindful that newly trained PAs require more mentoring and closer supervision than experienced PAs. A seasoned PA with emergency medicine experience will be more likely to hit the ground running, may work at a more rapid pace than a new graduate and be able to handle a higher volume of patients, but an experienced PA will command a higher salary and possibly a richer benefits package.
When looking for ED candidates, employers might wish to consider individuals with previous ED experience, either as a PA or in a previous career as a technician, paramedic, or nurse, for example. Very often, PAs who are drawn to emergency medicine have worked in emergency medicine in some capacity
before they became PAs.
The PA Role
As members of health care teams headed by physicians, PAs provide medical and surgical services that would otherwise be provided by physicians. Each PA's responsibilities depend on the type of practice, his or her experience, the working relationship with the supervising physician, the physician's or institution's decisions about what can be delegated, and state law. Though by law PAs are dependent practitioners, typically they exercise a considerable level of autonomy in clinical decision making. The relationship between the physician and PA is one of mutual trust and reliance. The physician trusts the PA to provide physician-quality care to patients seen by the team and to consult with the physician on those cases that are outside of the PA's scope of practice. The PA trusts the physician to be available for supervision, to provide learned advice, and to accept the care of patients with serious or complex problems.
The Society of Emergency Medicine Physician Assistants (SEMPA) offers guidelines on the role of PAs in emergency departments.4 According to SEMPA's guidelines, PA practice commonly includes, but is not limited to, taking patient histories and performing physical examinations; recording or dictating the information; ordering, performing, or assisting in the performance of laboratory and patient screening procedures; initiating basic and advanced life support; and initiating IV therapy by peripheral, central, intraosseous routes, and venous cutdowns.
The guidelines note that PAs commonly perform injections; arterial puncture; venipuncture; arterial line insertion; thoracentesis; lumbar puncture; wound care, including debridement; suturing; incision and drainage of abscesses; reduction of closed dislocations and fractures; application of casts and splints; nasogastric intubation; removal of foreign bodies (including sutures); EKG; urethral catheterization; arthrocentesis; endotracheal intubation; local, digital, and IV regional nerve blocks; administration of medicines; referring patients to appropriate follow-up care or community resources; and other interventions and procedures as directed by the supervising physician.
In 1999 the American College of Emergency Physicians surveyed PAs to identify their work environment, their postgraduate needs, and the procedures PAs perform. George Molzen, M.D., ACEP board liaison to the task force conducting the survey, concluded that the PAs are in emergency departments "side by side with the physicians, picking up the next patient." The ACEP report showed that patients usually are randomly assigned to PAs (see Chart 1). A high percentage of PAs performs endotracheal intubation and reduces fractures (see Chart 2).
Hospital Issues
In general, PA practice is not delineated by detailed treatment protocols. Emergency departments may be an exception to the rule, because physicians commonly use protocols and clinical guidelines in emergency practice. When physicians use protocols or clinical guidelines, it is appropriate for PAs use them, too. What is not appropriate is defining PA practice by the use of detailed protocols specifically written for PAs. PA education, like physician education, promotes the development of practical skills in clinical problem solving and decision making. It is more practical and establishes better teamwork and communication when the PA and physician work together under a broad practice agreement that allows the PA to exercise his or her clinical judgment while consulting the supervising physician as appropriate and necessary.
Cost-Effectiveness and Efficency
Utilizing physician assistants in emergency departments has proven to be both cost-effective and efficient. The state of the current health care system is such that many emergency departments are facing severe budget restrictions. Physician assistants can perform many of the tasks traditionally performed by physicians, but at lower cost. In rural areas in particular, PAs often provide access to care that otherwise would not be available.
