Top Deficiencies Cited by
JCAHO and CAP
4
COMPETENCY & the
NEW employee

Must complete an Initial Training,
before patient testing


Must complete semi-annually
competency during the first year of
duties, by 6 months
Continue with current staff on an
annual basis
5
COMPETENCY
New Equipment – “non-waived” testing
Retain Original Training Documents!!


Implementation of new methodologies must have documentation
of Initial Training (i.e. iSTAT1 to Gem3500).
Even if the analyzer is an upgrade must retain original training
material (i.e. iSTAT 200 to iSTAT1 – Signature Plus to Elite).

Save this documentation as long as the analyzer is available
for patient testing.
6
CREDENTIALS
Testing Personnel Limitations

Perfusion Certification is not a “CLIA
defined eligibility route” –
may be asked to produce H.S. Diploma

Know who is permitted to be classified as
Testing Personnel.
For example, in CA – Perfusionists are exempt from the lab licensing
for patient testing, but staff like Perfusion Assistants or Anesthesia
Technicians, are not.
7
QUALITY CONTROL
Failures



If have a ‘wet’ failure on an analyzer that uses EQC, carefully
determine C.A. before proceeding.
Do not continue to repeat ‘wets’ until get one in-range!
Two consecutive ‘wet’ failures in a row will trigger a repeat of the
10 or 30 day EQC study – depending on the analyzer.
8
TEMERATURES
Refrigerator & Room



If supplies (cartridges, QC) are being stored in a small local
(O.R.) Refrigerator, there must be indication of
temperature monitoring.
CAP requires daily.
If Refrigerator is not hard wired to Engineering or
continuously monitored in some manner, must be
manual documentation.
If have supplies kept at Room Temp, such as cartridges,
should have a monitoring system also.
9
TEMERATURE
Documentation
•
•
acceptable range
- C or F must be consistent
- tightest range in use, (iSTAT 18-30 RT while Gem Cart 15-25)
daily temp in addition to Min/Max
–
Daily is specified in CAP Checklist standards!
•
area for corrective action
•
explanation of date w/out temp recorded
•
monthly review w/ date & initials

ROTEM® vs. TEG 5000®
GENERAL INFO
– Incorporated in July 2008
– Primarily targeted
researchers at the start
– 2-test approval 3/23/10,
in-tem & hep-tem
– Additional 3 tests approved
8/12/11

28
ROTEM vs. TEG 5000
PRINCIPLE
Rotational
Thromboelastometry
trademarked by Rotem
Principle: pin oscillates as
the cup remains
stationary & as clot forms
rotation becomes
restricted & clot firmness
detected optically
Classical or ‘Original’ method:
Thromboelastography – originally
described by H. Hartert in 1948 &
trademarked by Haemoscope.
Principle: cuvette is rotated and as
clot forms it links the pin & cup
together; movement of the pin is
converted to electrical signals
