quality control Flashcards
quality assurance
deals with people
quality control
deals with instrumentation and equipment
SMDA
Safe Medical Devices Act
mandates that any serious injury or death due to medical device be reported
MQSA
Mammography Quality Standards Act
requires mammography facilities to be approved by the FDA
FOCUS-PDCA
the premier quality measurement consulting book
what does FOCUS stand for
F ind a process to improve
O rganize an effort to work on improvement
C larify current knowledge of the process
U nderstand process variation and capability
S elect a strategy for continued improvement
What does PDCA stand for
P lan D o C heck A ct it is a way of continuously checking progress in each step of FOCUS
outcome analysis
if the patients disease agrees with the radiologist’s diagnosis
T or F
the QA activities should all be monitored by the imaging team, however they are principally the responsibility of the radiologist
TRUE
QC DEALS MORE WITH?
THE EQUIPMENT
WHAT ARE OTHER REASONS FOR DOING QC BESIDES PATIENT CARE
our litigious society demands QC records
some insurance companies will only reimburse if there’s a QC program
JCAHO will not approve a facility that doesn’t have a QC program
most states require it
an acceptable QC program has 3 steps
acceptance testing
routine performance monitoring
error maintenance
T or F
periodic monitoring of equipment is required
TRUE
T or F
annual monitoring is acceptable unless there is a new piece of equipment installed
TRUE
acceptance testing
performed before newly installed or majorly repaired equipment can be accepted by dept.
determines whether equip. is performing within the vendor’s specifications
acceptance testing is done by someone other than the manufacturer’s rep for example
radiation physicist
service personnel employed by hospital
Routine maintenance
performed to ensure that the equipment is performing as expected
helps to catch problems before they become radiographically apparent
Preventative maintenance PM
usually alleviates unnecessary repair
if equip. is not performing up to standards then repair is necessary
error maintenance
when errors occur in equipment performance, corrective action must occur
filtration
the most important patient protection device
state requires radiographic units have a minimum total filtration of
2.5 mm Al
3 tools used to measure focal spot size and
pinhole camera
star pattern
slit camera (most popular)
line pair test tool is used to determine
spatial frequency
if the phototimer fails the backup timer should terminate the exposure at
6s or 600 mAs
whichever comes first
