  1. Working With NPI Numbers in Cancer Registries Jerri Linn Phillips, M.A. National Cancer Data Base Commission on Cancer American College of Surgeons Chun Chieh Lin, Ph.D. American Cancer Society

  2. Purpose This presentation will provide • Guidelines for manual and automated searches for NPI numbers • Recommendations for identifying incorrect numbers • Examples of administrative and research uses of NPI numbers

  3. NPI = National Provider Identifier • Organizational • Individual

  4. Organizational NPI: Hospitals • Electronic linkage by hospital name to NPPES NPI files • Most fail to find matches • “Multiple listings” per hospital • Manual look-up • Not as flexible • But can usually interpret best match visually • Useful for generating rules for linkage

  5. Problems Matching by Name Problem Example CoC: Provena Saint Joseph Medical Center Official: Presence Hospitals PRV DBA: Presence Saint Joseph Medical Center • Names differ, but recognizable to manual review

  6. Problems Matching by Name Problem Example CoC: Northwest Healthcare Official: Kalispell Regional Medical Center Inc DBA: NW Healthcare • How many ways can one write the same thing? • Saint • St. • St (no period)

  7. Does the NPI Refer to a Hospital? • For hospitals, CoC requests that they report the NPI for the full hospital • Not the campus, department, or network • 95% of NPIs cleared by NCDB are identified as a hospital as their principle category • Another 3% identify hospital as a category, but not their principle one • CoC has a handful of free-standing non-hospital clinic programs

  8. Secrets for Selecting the Best NPI • Obvious: the hospital name and address match, at least to the human mind • Separate address for administration, practice • What is the title of the authorized official? • A highly-ranked official • President, CEO, vice president or CEO • Billing, finance officer, or similar designation • Never: Resident, chief surgeon, nurse • Exception: VA

  9. But if Multiple Options Remain • I look for the NPI that identifies billing codes for: • The most providers • Both Medicaid and Medicare • At least Medicare • A small number of CoC-accredited programs appear not to accept either Medicaid or Medicare, but have NPI numbers

  10. Tracking It Down When Name Totally Fails • Manually: • Zip Code is the narrowest identifier if name does not work • Play detective: Karmanos example

  11. Electronic Recommendations • Check both legal and DBA name fields • Use your case-linkage software to discover similar names • Subset by ZIP Code, perhaps by organization type OR • Strip punctuation, perhaps spaces, put “Saint” into constant form across the board • If nothing else works, consider looking for “contains” key portion of hospital name • Check taxonomy codes (Maximum of 4 in April 2013 organization entities)

  12. As For Any Record Linkage … Visual Check

  13. Individual NPIs: Physicians Primary Surgeon NPI Radiation Oncologist NPI Medical Oncologist NPI

  14. Completeness for each NPI field (Lung) Prim Surg Phys 3: Rad Onc Phys 4: Med Onc

  15. For Surgery (Lung Cancer) • Top 3 specialties relevant to lung surgery (> 90%) • Thoracic Surgery (64.16%) • Surgery (18.77%) • Specialist (7.52%) • Examples of clearly bad NPI • Internal Medicine (0.27%) • Student in education/training program (0.22%) • Dermatology (0.07%) • OB/GYN (0.02%) • Sleep Medicine (0.01%) • Psychologist (0.01%)

  16. For Radiation Therapy (Lung Cancer) • For radiation given in reporting facilities • 18,306(87%) relevant to lung radiation • Radiation Oncology (83%) • Therapeutic Radiology (4%) • Radiation Therapy (0.03%) • 228(1.08%) relevant to medical oncology • For radiation given outside reporting facilities • 5877(83.7%) relevant to lung radiation • Radiation Oncology (80%) • Therapeutic Radiology (3.62%) • Radiation Therapy (0.19%) • 243(3.46%) relevant to medical oncology

  17. For Chemotherapy (Lung Cancer) • 12,795(81.2%) relevant to medical oncology • Hematology & Oncology • Medical Oncology • Hematology • 144(1%) relevant to radiation

  18. For Coded NPI: Was the Treatment Actually Given? (Lung Cancer) ¹Surgical treatment includes any surgical procedures (biopsy, resection or NOS) ²Radiation treatment includes radiation therapy was given either in reporting facility or outside reporting facility

  19. For Surgery Received: Top NPI Categories by Stage
