2 PAs: A Workforce Policy Success in the U.S. Over the past 50 years, the PA concept has been shown to be a remarkable workforce policy success: Prescribing in all states Reimbursement through all third-party payers High demand in the medical marketplace Utilization and new roles are expanding Clinical flexibility Patients accept PAs; a poll showed that 66% of citizens recognize the PA role and one-third have been treated by a PA (AAPA, 2007) The career is attractive with high levels of job satisfaction mean salary is $102,000/year. High levels of job and career satisfaction among PAs. One obvious factor: PAs complement physician practices and do not threaten physician roles or authority The PA concept is spreading globally with programs now in Canada, England, Scotland, Australia, Saudi Arabia, Ghana, and the Netherlands PAs have shown remarkable clinical mobility across medical specialties and settings Hooker, RS, Cawley, JF, Asprey, DP.

4 Profile of PA Characteristic 2013 Licensed PAs ~90,000 Female 65% Primary Care 33% Age (mean) Length in Practice (mean) Length in Current Specialty (mean) 42 years 9 years 4 years Inpatient Hospital Unit 18% Emergency Department 14% Hospital Based (includes OR, Outpatient, ED, and Inpatient) 47% Hooker & Muchow, 2013: Provider 360 Database, AAPA 2013 Census.

5 PAs A physician assistant (PA) is nationally certified and state licensed to practice medicine as part of a physician-led team. PAs are educated at the graduate level and practice in nearly every medical specialty and setting. Scope of Practice Obtain medical histories Conduct physical exams Diagnose and treat illnesses Order and interpret tests Counsel on preventive healthcare Assist in surgery Write prescriptions Make rounds in nursing homes and hospitals * PAs responsibilities correspond to their supervising physicians practice.

6 PA Workforce is Youthful and Female PA Supply by Age and Sex, ,000 2,500 Female Male 2,000 1,500 1, Age

7 Supply of PAs There are 182 accredited PA programs in the US with an additional 60 programs in the accreditation pipeline The vast majority of total PA graduates (over 100,000) are in active clinical practice = 89,500 There are approximately 7000 annual PA graduates Annual attrition is low = 2.9% annually (est)

8 Shortages projected for both primary care and subspecialists Primary Care Subspecialties ,000 4, ,800 33, ,400 46,100 Hofer et al 2011; Hooker 2012; Lewin for AAMC, 2011; Huang & Finegold 2013

9 Primary Care in America: Percentage of Providers Identified in Primary Care NPs MD/DOs PAs 30 20

10 Trends in Emergency Medicine The role of NP/PAs in emergency medicine is varied but spans the same degree of care as doctors Many PA/NPs staff fast-track (urgent care) In US EDs, there is one PA/NP for every five doctors ED: fast growth for PAs since 2000 Team based care studies are needed to understand the dynamics and interaction of the players Hooker, Cipher 2008

11 PAs on Inpatient Services Can provide the full range of clinical services required No decline in quality of care Enhance the educational experiences of residents Provide an element of continuity to inpatient services Cawley, J.F., Hooker, R.S.

12 US PA and NP Graduates Per Year ( ) Hooker et al 2013; 2011 PAEA & AACN data

13 Demand: Enrollment of 30 million newly insured Aging population Sustainability of chronic diseases The Effect of Health Reform New technology (pharmacy, techniques, tools) Quality and cost-effectiveness imperatives Electronic health records Consolidation of small and medium size practices Hospitalization Supply Physicians: 18,000 25,000 new graduates PAs: 7,000 new graduates annually Young profession (mean age = 42) Career span: 35 years

14 Going Forward PAs are a vital and flexible component of the US health care workforce The supply of PAs is expected to grow steadily over the next decade PAs are team-oriented, have training as medical generalists, and seek a practice stance closely aligned with physicians
