- Observe NGS read alignment, variant calling and confirmation
- Understand the analysis of NGS data with respect to the bioinformatics and statistical components
Practice Based Learning and Improvement
- Understand the use of quality assurance and control in the molecular laboratory.
- Explain 'unidirectional flow' with regards to contamination prevention and effective strategies for contamination prevention, with respect to the appropriate design and workflow in molecular laboratories to ensure quality and reduce the risk of carry-over contamination
- Able to interpret quality parameters to determine the quality of extracted nucleic acids.
- Analyze and interpret sequencing data for solid tumor, hematopathology, infectious disease, and inherited diseases specimens, including appropriate reporting and medical significance of positive and negative test results.
- Perform a literature search on an assigned clinical test and give a presentation to the UHTL faculty and staff.
- Convey information to laboratory staff in a timely manner
- Reading independently on topics related to patient case material and search primary sources
- Demonstrate self-motivation and organization in pursuit of rotation requirements (reading and clinical service time)
- Demonstrate a commitment to ethical principles pertaining to (1) patient privacy and autonomy, (2) the provision or withholding of test results, (3) confidentiality of patient information, (4) informed consent, (5) conflict of interest, and (6) business practices that are in conflict with stated principles of professionalism.
- Demonstrate courteous and collegial behavior with laboratory staff (laboratory supervisor will evaluate resident based on input from laboratory personnel)
Interpersonal and Communication Skills
- To effectively communicate with clinicians about test ordering and test results with appropriate interpretation.
- To effectively communicate with lab staff about appropriate sample identification and selection, issues regarding test result interpretation and trouble-shooting
- Understand concepts of laboratory design and procedure that are specific to nucleic acid testing.
- Understand primary issues of QA/QC in molecular amplification, including common sources of false positive and negative results, and basic trouble-shooting
- Explain the regulatory requirements governing all molecular tests, including laboratory developed tests, and compare the differences and similarities among them.
- Define the test designations RUO, IUO, ASR, IVD, and LDT
- Describe the validation process for a lab developed test and requirements for lot validation for all test types.
- Contrast verification of an IVD with validation of an LDT
- Explain the important legal, ethical, and social implications with regards to larger scale/genomic testing and the ability to 'blind' analytes to prevent unintended data analysis (i.e. NGS for tumor discovering AD condition)
- Integrate molecular diagnostic results into hematopathology, inherited disease, infectious disease, and solid tumors pathology reports
- Act as a consultant to clinicians and other pathologists for the use and selection of molecular testing. Provide appropriate consultations regarding test results.
- Perform an evaluation of lab quality control and quality assurance program.
The rotation in molecular pathology is four weeks and typically occurs during years 3 or 4 at the UHTL.
Duties and Responsibilities of Residents
- Because the core curriculum is taught at one point in the Resident's training, responsibilities do not change on a yearly basis.
- Review incoming cases for order accuracy and follow up on questions to ordering providers
- Review and sign out all results with the Attending Pathologist
- Review laboratory procedures
- Participate in division case conference, QA meetings, and other meetings as applicable
- Present briefly (15 min) on a relevant topic to the UHTL faculty and staff
- Jennifer Yoest, MD - Rotation Director
- Navid Sadri, MD, PhD - Division Director
Supervision and Evaluation
Residents meet on a regular basis with the Attending Pathologist and with the lead technologists for supervision. Residents are evaluated on a monthly basis with regard to acquisition of the Core Competencies listed in this Program Statement. Evaluations are forwarded to the Residency Program Director, where they are available for review. Direct observation and feedback. In addition, residents may take pre- and/or post-rotation examination.
