  2. ECONOMICS, EDUCATION, AND HEALTH SYSTEMS RESEARCH SECTION EDITOR RONALD D. MILLER An Updated View of the National Anesthesia Personnel Shortfall Armin Schubert, MD, MBA*, Gifford Eckhout, Jr., MD*, and Kevin Tremper, MD, PhD† *Department of General Anesthesiology, The Cleveland Clinic Foundation, Cleveland, Ohio; and †Department of Anesthesiology, University of Michigan, Ann Arbor, Michigan ANESTH ANALG SCHUBERT ET AL. 2003;96:207–14

  3. Assessing WorkForce Balance& (Carefully) Diffusing the Information • Credibility • Timeliness • Availability

  4. WorkForce Balance Assessment Surveys, vacancies, anecdotes ……..MODEL Construction  Supply Factors Additions Losses Demand Factors Locations, facilities, procedures Population age & health demographics Special Factors to be used sparingly

  5. Anesthesia “Trend” Model Construction • Vs. “needs” (social construction - what “ought to” occur) • Uses established historical supply/demand trends • Predicts near term from residency enrollment trends • Predicts future demand based on….. • immediate past history • estimated disease & population growth • Calculates present and predicted workforce balance • Deals with growth uncertainty: 2 scenarios * Snyderman, Health Affairs, Jan/Feb2002 * Cooper, Health Affairs, Mar/Apr 2002

  6. Model Assumptions- Supply • Starting Point: In -balance: 1994 • Supply information from Grogono/ABA • Graduates (minus J-visa losses) • Projected attrition • Fellowship losses (assume constancy) • Losses: • Retirement (ASA membership age distribution) • 90% workforce participation by women • Other part-time & non-clinical (assume constancy)

  7. AMG & IMG Anesthesia Residents by Year of Training Grogono A, ASA Newsletter November 2003

  8. Cohort Attrition: Early vs. Late ‘90’s Grogono A, ASA Newsletters Modified by G. Eckhout, 2003

  9. Tremper KK, et al. Advances in Anesthesia

  10. Retirement • ASA commissioned survey in 2002 (Tarrance Group; hospitals with >100 beds) • 34% response rate (2363 US hospitals) • Assume: - related to anesthesiologists only • - only one group served each hospital • Estimated retirements/yr = 800 • ASA Retirements/yr = 400; total < 600

  11. Tremper KK, et al. Advances in Anesthesia

  12. Model Assumptions - Demand • No change in care model (ratios) • Growth: 1994 -2001: 2.0 vs. 3.0% 2002- 2003: 1.5 vs. 2.0% 2004- 2007: 1.5%

  13. =8-9% Facility growth annually

  14. Surgical Demand Growth SMG Estimates 2003

  15. Population 65 years of age and over: United States, 1950-2030 90 80 65 years and older 70 85 years and older 60 50 40 30 20 10 0 1950 1960 1970 1980 1990 2000 2010 2020 2030 Schubert et al, Mayo Clin Proc, 2001

  16. Growth in Surgical Procedures: Carotid & Spine Schubert et al, Mayo Clin Proc 2001

  17. Surgical Volume Trends Source: AHA, SMG

  18. Surgical Workload 2001-2020Methods • 2001-2020 US Census data • 1996 NHDS and NSAS • 7 specialties • 214 representative procedures • Physician work component of RVU • Age specific incidence rates for each procedure multiplied by RVU Etzioni et al, Ann Surg 238:170,2003

  19. Surgical Workload 2001-2020Results • Each specialty accounted for 13-15% of total workload • 58% of procedures associated with age>65 • Workload increase 30-35% • Annually 1.3-1.5% • Surgeons to operate more, train more • All of the above will  anesthesia demand Etzioni et al, Ann Surg 238:170,2003

  20. Demand for Anesthesia Services Health Care Demands of the US Population • Growth in Surgical Procedures (next 5 years) Outpatient, hospital (3-4%) Inpatient (-1%) Outpatient-freestanding (4.5-6%) Office-based (1.5-3.5%) • Geriatric procedures tripled • Chronic pain (5%), obesity, critical care AHA - CDC/NCHS - SMG US Census Bureau - HRSA

  21. Other Considerations • CRNA’s • DO’s • Historical Resident Production • Malpractice Environment • Nurses & Propofol Administration • Robotic Technology • Etc.

  25. Surveys • ASA-Tarrance Group • Ohio Society of Anesthesiologists • ASA On-line Membership Survey • Recruiting Firms & Position Ads • SAAC-AAPD

  26. August: SAAC/AAPD Survey = 568 open positions; If 20% of Workforce is academic, shortage estimate=2800 Courtesy of K. Tremper, MD, PhD. In 2003, 67% of programs have OPEN CRNA positions

  27. Tarrance Group ASA Hospital (>100 bed) Administrator Surveys • 43% limited ORs due to shortage • 43% said their hosp has too few anesthesiologists • 59% said they were currently recruiting • If vacancy/hosp is 1.6, shortage estimates = 1600-2200 vacancies • If avg 3 rural hosp. Served by one group, add at least 100 more to shortage estimate • Shortage estimate of 1700-2300 The Tarrance Group, August 2002 Abenstein et al, Anesthesiology, A-1131, 2002

  28. OHIO Society of Anesthesiologists Membership Surveys Pos Vac 2001 2003 1 22% 22% MD>1 39% 35% avg 1.7 1.6 CRNA1 10% 12% >1 45% 44% avg 2.3 1.8 37 groups  60 pos; extrapolated to US  2200 vacant

  29. Summary of Model Predictions • 2001 shortage 3.6-10.9% of supply • 1200-3800 full time positions • Similar shortfall will persist until 2005 • Thereafter, prediction is dependent on annual demand growth 2% demand growth = 10% Shortage 1.5% demand growth = Shortage stops • 15% annually in residency positions to achieve equilibrium by 2010

  30. Updated Assessment 2002 • Surveys: OSA, Tarrance Grp; SAAC/AAPD • SAAC-AAPD (no change from 2001) • Our 2003 “best estimate” of shortage: 1100 - 3800 in 2002 700 - 3900 in 2005 • Trainee growth slower than originally predicted; fewer IMGs • Demand growth was higher than assumed “No Change”

  31. 2003 Update Despite resident entry ’g to 1600, shortage continues, if somewhat less severe. • New data from AMA, HRSA, ABA • Trainee growth slower than originally predicted; fewer IMGs • Demand data from SMG (> than orig.) • Model points to mild oversupply in 1994 • Our current “best estimate” of shortage: 2003: 2600 2005: 2300 2008: 1900

  32. Workforce Model

  33. Predicted Anesthesiologist Shortfall - Original

  34. Predicted Anesthesiologist Shortfall - New

  35. How Many To Train? Centralized Management • Formulas: underestimate MD workforce needs Haase, Ann Emerg Med 1996 • ABT Report: underestimated AN need • DGME Cap:3468 (= 900/year: dbls shortage by 2010) Market Forces • “Education Pipeline” • Recent Match Data: Continuing high interest but numbers similar to 1994, despite  demand and 7 years of drought; 5-6 year “pipeline” Our Personnel Model: • 1.5% growth: need 1600/yr to 2010 • Kindig, JAMA v.270,1993 • Meyer et al, JAMA v. 276, 1996

  36. In a 2002 survey of medical students attending the AMSA Annual Meeting….. • 14% (16/112) still reported being discouraged from entering anesthesia because of • “too many people in the field” • “shortage of positions” • “potential for forced primary care” Curry & Bralliar, Anesthesiology A1101, Oct 2002

  37. Market forces can be expected to work well only with timely & accurate information. • Annual workforce supply and demand review • Credible, impartial, competent • Input from academia, practice & government • Assessment of present & future • Widely publicized: Medical students, advisors • ASA, AMA, AAMC, COGME, GMENAC…..??

  38. ASA Committee on Physician ResourcesDATA Repository for Anesthesia Workforce (DRAW) • ASA supported • Accessible, up-datable resources • Supply - Demand - Balance • Reviewed by committee members • Assembled into model • To be available on dedicated web space • Access for students, advisors, flex personnel
