Use of APRNs in Primary Care Settings

Some health care problems must be addressed whatever happens with reform. High on the list is the supply of primary care professionals.  Shortages have been reported in Massachusetts, and primary care access concerns have been raised in national reform discussions.  The shortage of primary care physicians is often tied to their low income, compared to specialists, and the consequent diversion of medical graduates to specialties.  The shortage of primary (and in some areas, specialty) physicians has prompted recommendations for increased medical school enrollment and residency slots for all areas of medical practice.

The wisdom of pumping up physician supply has been questioned.   It has been noted that, beyond a low threshold, increasing specialty physician supply is poorly correlated with better outcomes, and that previous efforts to increase supply has made the rich richer and the poor poorer, as graduates have flocked to locales and specialties already well-served by physicians.

So what is the proper policy response to a shortage of primary care physicians?  Physicians claim exclusive control of a broad swath of professional practice.  They dominate primary care, and exclusively control a more and more finely differentiated series of specialty fields.  With power comes responsibility, one might think.  Richard Cooper, a leading analyst of physician supply, commented in 2002 (at a time when many saw a surplus, not a shortage, of physicians) in an article with colleagues on the ramifications of this broad near-monopoly in a profession with falling production and fixed supply:

The sociologist Andrew Abbott has observed that “a profession whose jurisdiction is excessive must increase its productivity or expand its numbers.” Conversely, “when a powerful profession ignores a potential clientele, paraprofessionals appear to provide the needed services.” These statements characterize the dilemma that physicians now face. Their ability to increase their productivity is limited by their declining work effort. Their ability to grow their numbers is hostage to the belief that surpluses exist. And organized medicine has embarked on a vigorous campaign to thwart expansion of the NPC [non-physician clinician] disciplines. Yet it was shortages in the past that motivated state legislatures to remove the barriers to licensure for NPCs and to enlarge their range of privileges, and it is perceived professional opportunities that stimulated the creation of new disciplines and the expansion of existing ones. (footnotes omitted)

So, health reform efforts have emphasized access to primary care for its beneficial effects, while the supply of primary care docs has suffered a flight to specialty practice.  Is it, as Cooper suggested, time to rethink the place of non-physician caregivers on the front line of primary care?  As advanced practice registered nurses (”APRNs”) have gradually increased their scope of practice, studies and meta-studies have found that outcomes are equivalent when services are provided by a physician or APRN, and patients satisfaction measures may favor nurse practitioners.

But what about the nursing shortage?  It may be that expanding the profile and responsibilities of APRNs could further efforts to recruit and retain nurses.  Talented, hard-working nurses have long been concerned that their career path is limited; their salary steps are few and shallow, and they are unable to gain responsibility and autonomy commensurate with their training and experience.  Facilitating RNs’ graduate education to allow licensure as advanced practice nurses would enrich their career paths and encourage then to remain in the profession.   To move in this direction, those states that have not done so could expand the scope of licensure of APRNs to permit more fully independent primary care practice options.   The length of time needed for education and training would be long, but not as long as for physicians; compensation would have to be increased to reflect a higher level of training and responsibility, but not to the compensation level of physicians.

The path to regularizing the scope of practice for APRNs is described in a 2008 consensus document endorsed by 39 national general nursing and nursing specialty organizations.  A 2009 report from the Connecticut Office of Legislative Research described that state’s APRN scope of practice:

Advanced practice registered nursing is defined as the performance of advanced level nursing practice activities that, by virtue of postbasic specialized education and experience, are appropriate to and may be performed by an APRN. The APRN performs acts of diagnosis, and treatment of alterations in health status and must collaborate with a Connecticut-licensed physician. In all settings, the APRN may, in collaboration with a licensed physician, prescribe, dispense, and administer medical therapeutics and corrective measures and may request, sign for, receive, and dispense drug samples.

The required “collaboration” with physicians was also described:

The law defines “collaboration” as a mutually agreed upon relationship between an APRN and a physician who is educated, trained, or has relevant experience that is related to the work of the APRN. The collaboration must address a reasonable and appropriate level of consultation and referral, patient coverage in the absence of the APRN, a method to review patient outcomes, and a method of disclosing the relationship to the patient.

The physician oversight rule is typical, and has been the source of tension with APRNs.   Physicians can be suspicious of APRNs, and it has even been suggested that physicians may avoid working with them as APRNs gain more autonomy — a reaction that could be fueled by concerns with APRNs’ competency and training, or by a desire to weaken a source of competition for control of the profession.

APRNs might fill the primary care end of the physician practice spectrum, should physicians continue to flee primary care for more remunerative specialties.  There are genuine professional competency issues to work out, but they ought not be resolved by physicians as a matter of naked market power.  In addition, the terms of appropriate collaboration between physicians and APRNs need to be ironed out, to protect patients while avoiding the possibility of anti-competitive refusals to deal with APRNs.  Many researchers and physicians welcome the emergence of APRNs as partners in primary care practice.  Further research on the proper autonomous practice settings for APRNs will serve the interests of patients, and can guide planning for the future of primary care.
