history of ppm testing
History of PPM testing
  • CLIA Classifications
    • Waived
    • Moderate Complexity
    • PPMP
    • High Complexity
classification of tests cdc described the system
Classification of TestsCDC described the System
  • 7 categories were used to classify 1,200 original laboratory tests.
  • A point system was used in each category, 1-3.
  • 3 categories were associated with the analyst.
  • 3 were associated with the test
  • and one was calibration, QC and proficiency testing.
categories used for classification
Categories used for Classification
  • Knowledge
  • Training and Experience
  • Reagents or Material Preparation
  • Characteristics of the testing steps
  • QC, Calibration, Proficiency Testing
  • Trouble Shooting and Maintenance
  • Interpretation and Judgement of the Analyst.
poct at pinnacle health system
POCT at Pinnacle Health System
  • 1996 Merger of 3 hospitals, additional 1 hospital added in 1999.
  • Exception to Section 5.22(f)(to direct more than two laboratories)
  • Inpatient POCT
  • Outpatient POCT
  • Training/Competency Testing of Resident and Staff Physicians over the last 5 years at ~ 30 out-patient sites and in-patient employed physicians. (200 Practitioners)

criteria to qualify for a ppm license
The examination must be performed by a Physician, Mid Level Practitioner, or a Dentist

The procedure must be classified as Moderately Complex

The microscope must be of the bright field or phase contrast type.

The specimen is labile or delay will compromise the accuracy of the test.

Control materials are not available for the entire testing process.

Limited specimen handling or processing

Criteria to Qualify for a PPM License
common ppm tests moderately complex tests
Wet Mounts- vaginal, cervical and skin

All Potassium (KOH) preparations

Pinworm Exams

Fern Test

Post-coital direct, qualitative exam of vaginal or cervical mucous

Nasal smears for eosinophils

Microscopic urinalysis

Fecal leukocyte examination

Semen analysis, or sperm motility

*This is different from the PPT tests for CAP

Common PPM Tests* (Moderately Complex Tests)
regulated physician testing
Regulated Physician Testing
  • CAP - PPT (Physician Performed Testing- includes a different menu compared to PPMP)
  • Both Waived and PPMP tests are included.
    • Amniotic fluid pH
    • Gastric biopsy for urease
    • Occult blood, fecal and gastric
    • Synovial fluid for crystals
    • Urine dipstick
personnel requirements
Personnel Requirements
  • Confined to Physicians, Midlevel practitioners, and Dentists.
  • Other requirements for this test differ by agency

pinnacle health system procedure
Pinnacle Health System Procedure
  • PPM procedures in place 12/1997
  • Training of Docs began 1/1998
  • Paper competencies began 1998.
  • On-line competencies began 2000.
    • Tests included, Wet mount all types, KOH, pin worm preparation, gram stains (one clinic only), urine microscopic, PPT testing (one clinic only- Docs at other clinics have other analysts performing tests.)
twice a year ppm
Twice a year PPM
  • Performed for first time users, live sample presentation with Dawn, Jenny and myself.
  • Primarily for residents.
  • Every 6 months to assess competency of analyst and for procedure verification.
resident training
Resident Training
  • First Year residents in Family Practice and Internal Medicine (key- make it practical and interesting!)
  • Scheduled time with all of them at once.
  • Power Point, slides, “wet samples”.
  • Formalized to include “other parameters”
    • including-CLIA regulations, office practice, technical presentation on PPM, costs of tests, collection of samples, in-depth tour of entire laboratory, predictive value of lab tests.
physician competencies
Physician Competencies
  • Over 200 performed twice a year
  • Pictures you are seeing are those used.
  • Always have an educational sample
  • Key-teach them
  • Don’t just satisfy the regs.
