47
What is involved in retrospective rescreening of gyne cyto specimens
If current sample shows high grade abnormality, screening technologist pulls and rescreens the patient's neg gyne cyto slides from the previous 5y. All slides referred to pathologist for review Corrected report issued only when findings on rescreening change the patient's current management Findings used for educational feedback
48

78
How is root cause analysis done
Variety of techniques - cause mapping, change analysis, Ishikawa fishbone diagram, 5 whys Process poses 3 questions: 1. what was the problem 2. What were the causes of the problem 3. What actions should be taken to prevent the problem from recurring
79
What should you do if you notice that one of your colleagues has made a diagnostic erre that could impact the care of the patient
1. Discuss case with colleague 2. If they agree - they should inform clinician and issue amended report 3. If disagree - third opinion should be sought 4. Notify clinician so not irreversible clinican management takes plae before diagreement is resolved 5. If colleague refuses to seek third opinion, notify lab medical director
80
A surgeon approaches you because they strongly disagree with a diagnosis your colleague has made. What do you do?
Obtain clinical information as to the nature of the disagreement and surgeon's reasons for not approaching your colleague directly Review case Discuss situation with colleague If there is new information, collaborate with colleague to issue an addendum or corrected/amended report
81
If a surgeon asks you to review all the cases your colleague signs out, what do you do?
Clarify reason for request Contact lab medical director to manage the issue
82
