Nurses, Prescriptions and Pharma Influence– Under the Radar?

Very interesting point made over at Gary Schwitzer’s Health News Review Blog regarding Industry funding of Continuing Medical Education (CME) for Nurse Practitioners (if you’ve never visited Mr. Schwitzer’s blog you should, he is informative, well written and generally brief).

Seton Hall Law’s Center for Health & Pharmaceutical Law & Policy issued a White Paper last year, “Drug and Device Promotion: Charting a Course for Policy Reform,” which called for a cessation of industry funding of CME. The Center noted:

Reforming Funding for Continuing Medical Education (CME). Most states require physicians to undertake continuing medical education to maintain their medical license. The drug and device industry currently funds over half of the accredited CME courses available to physicians. The Center recommends that industry funding for continuing medical education should be phased out, and replaced by an educational process driven by physicians.

And that

• Ninety-four percent of physicians have some kind of financial relationship with industry, as reported in a major recent national study.

• Commercial support for accredited CME, nearly all of it from drug and device manufacturers, grew from $302 million in 1998 to $1.2 billion in 2006.

But what about nurse practitioners? Schwitzer, who attended the recent Georgetown Conference, “Prescription for Conflict: Should Industry Fund Continuing Medical Education?” noted that:

There are more nurse practitioners (147,000) than there are family physicians (100,000) in the US.

These advance practice nurse professionals can write prescriptions, and it’s estimated that the average nurse practitioner writes more than 6,000 a year.

And about 70-80% of those nurses who regularly attended lunch or dinner “continuing education” events sponsored by drug companies said they were more likely to prescribe the drugs that were highlighted in the lunch.

The presenter was nurse-researcher Elissa Ladd, PhD, RN, Asst. Clinical Professor, Massachusetts General Hospital Institute of Health Professions, who says the possible pharma influence on nurse-prescribers has largely flown “under the radar.”

A little quick and basic math will give us some inkling of just how much flies under that radar. We’ll use the minimum figure in all estimates. So…

147,000 Nurse Practioners each writing 6,000 prescriptions per year = 882,000,000 prescriptions. Yes, that’s 882 million prescriptions per year– conservatively estimated.

“More likely to prescribe the drugs that were highlighted in the lunch” we can estimate at 51%. We wind up with a potentially influenced 449,820,000 prescriptions. Again, conservatively estimated.

So now the only question is just what percentage or how many Nurse Practitioners “regularly attended lunch or dinner ‘continuing education’ events sponsored by drug companies?”

With a total pool of over 882 million prescriptions per year available– at least 450 million of them potentially swayed over lunch–my guess is that Pharma’s answer would be “As many as possible.”

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.

Nurse Practitioners and the Allocation of Resources

In my last post, I made a rather conclusory (and parenthetical) statement regarding the utilization of nurse practitioners in retail health clinics. I wrote:

Retail health clinics have sprouted up across America as of late. They can be found in grocery stores and pharmacies, are open nights and weekends, often (wisely) utilize the services of nurse practitioners for minor ailments and feature a clearly listed schedule of fees.

Today I’ll clarify. The view espoused is largely based upon simple resource allocation theory: that one utilizes resources effectively by matching the need with the skill; that to underutilize is to engage in waste, and, given demand and a shortage of doctors, when a physician is attending to minor ailments, and charging physician rates to do so, society has experienced a net loss.

The trick of course is in a) making sure that there is a sufficient supply of well trained nurses (you may wish to take a look at this interesting RWJF blog from Susan Hasmiller, “projected shortage of 500,000 nurses by 2020,” despite the present difficulty of some nurses to find work ); and b) assuring that the need of the client is matched with the appropriate level of skill: that the service provider is capable.

According to the Mayo Clinic, “NPs are registered nurses (RNs) who are prepared, through advanced education and clinical training, to provide preventive and acute health-care services to individuals of all ages. Today, most NPs complete graduate-level education that leads to a master’s degree. They work independently and collaboratively on the health-care team.”

As to the capability of nurse practitioners, this quote (n. 14) from William M. Sage, Out of the Box: The Future of Retail Medical Clinics, Harvard Law And Policy Review Online (2009), is worth noting:

Debate over the relative merits of primary care from nurse practitioners and from physicians is purely rhetorical. A review of 11 trials and 23 observational studies in primary care settings concluded that “[q]uality of care was in some ways better for nurse practitioner consultations.” Sue Horrocks et al., Systematic Review of Whether Nurse Practitioners Working in Primary Care Can Provide Equivalent Care to Doctors, 324 BRIT. MED. J. 819, 819 (2002). See also Linda H. Aiken, Achieving an Interdisciplinary Workforce in Health Care, 348 NEW ENG. J. MED. 164 (2003) (editorial describing the quality of non-physician professionals); Mary O.
