Guide to Waived Testing at MCL-
Special Topics
Physician
performed tests
These have waived status, but may be performed only by physicians within
their scope of practice. Physician performed tests allowed by the Medical Center include Strep. A, Heliobacter Pylori and occult blood (e.g. Hemoccult).
Physician performed microscopy (PPM):
Physician performed microscopic exams
include such exams as urine sediment exam, qualitative semen exam, vaginal wet
preps, fern tests, pinworm preps, etc.
These are allowed under CLIA and are also exempt from proficiency testing. The Medical Center allows these procedures to be
performed by physicians within their appropriate specialty.
Regulatory
Requirements:
- The Health Care Financing
Authority (HCFA) requires institutions performing waived testing to have
an approved provider application. Once approved, the institution is issued
a "CLIA number". HCFA requires that personnel who perform
these tests have ongoing competency assessment and that testing procedures
are followed exactly in accordance with the manufacturer's
instructions.
- JCAHO requires laboratory oversight
to the performance of waived testing. In addition, the standards require
that we answer the following questions:
Question Our answer
|
Who may perform the test?
|
The list is maintained by
the Nurse Managers.
|
|
Which tests will be
performed?
|
See the above list of
approved tests.
|
|
Where the tests will be
performed?
|
List maintained by the
audit section.
|
|
Is the test for screening
or definitive use?
|
Hemocue – Definitive
All others Screening
|
- The MCLNO waived testing policy
meets both JCAHO and HCFA requirements. It also describes the oversight
process. The policy states that individual units may perform waived tests
provided that they meet all requirements. Nurse managers are responsible
for maintaining lists of personnel, competency records, quality control records and all other required documentation.
Other Notes:
- There is a detailed nursing
policy for glucose testing and for hemoglobin testing.
- Procedures for the rest of
the waived tests are available, in your waived test binder. These are in a
one-page format and cover test performance and quality control
requirements.
- Some tests have internal
controls, which are built in to verify that the test is working.
- Other tests require external
quality controls. These are independent sources of positive and negative
analytes. (see below)
- Oversight and audits: The
MCLNO policy describes the oversight and audit role.
- An auditor from the lab makes
unannounced visits to verify compliance.
- Corrective action is required
for any discovered deficiencies.
- The unit manager corrects
deficiencies and documents the process in writing.
- The oversight group reports
to the Clinical Laboratory Utilization Committee (CLUC) which recommends
status to the Executive Committee.
- Any units that fail to meet
waived test requirements will have their testing privileges revoked by the
Executive Committee.
Competency
and Quality Control:
- All waived tests require that
competency be verified on an annual basis. A competency checklist is
available for each procedure. Competency verification is reviewed in the
audit process. For urine dipstick and pregnancy, colorblind testing is
required.
- Quality Control requirements
vary by procedure as summarized in this table:
