MHH  Hematopathology

Category:                     core rotation

Training level:    introductory to advanced (the first month is taken within the initial
                                    eight months of residency training)

Length of rotation:         3 months, taken in 1-month increments

Location:                      MHH hematology lab, 1st floor Robertson

Rotation director:          Andy Nguyen, M.D.

 

Resident Duties

Working hours:  The resident is expected to be on duty from 8am to 5pm.

 

Service duties:  After the morning conference, the resident reviews all pending materials (bone marrow aspirate/biopsy, peripheral blood, body fluid, coagulation, flow cytometry) and prepares a draft for interpretation using all laboratory and clinical data including those from CERNER LIS and EMR.  Cases with complete data are signed out with the attending.  Note that if bone marrow procedures are scheduled, the sign-out schedule will be changed accordingly.  Different residents will be assigned different tasks depending on level of training.

 

The attending will edit and release reports while the resident reviews unknowns (taken from study sets) if time permits (unknowns may not be given on a very busy day).  The resident meets with the attending at 1pm or 2pm (depending on bone marrow slide availability) to review bone marrow aspirates obtained in the morning & other pending cases, and also to review the unknowns.  The resident meets with the attending at 3pm or 4pm (depending on coagulation data availability) to sign out coagulation cases. 

Note that the resident needs to check on all pending cases in the laboratory (hemepath, coagulation cases) throughout the day and to prepare drafts for the reports before signing out with the attending.

 

Lymph node cases that are referred from Surgical Pathology for consultation are also reviewed and signed out with the attending in the Hematology Laboratory.

 

Typically, one to two pathology residents are on the rotation each month.  The resident will also work with other trainees on the rotation (one UT/MDA hematology-oncology fellow/month, 1-3 fourth-year medical students/month, 4-5 MDA hemepath fellows/year, 2 TMH hemepath fellows/year).

 

After hours/weekends:  Residents take night and weekend call per the global DPALM CP call schedule.

 

Conferences:  Residents are required to participate in 8am UTHMS teaching conferences, 3pm CP conferences, and the once-monthly CAP lab management audio conference, unless prohibited from doing so by urgent service duties.  Select cases will be chosen for presentation by the resident in the 3pm CP Conferences.  Hematopathology journal articles of interest are also selected and presented once a month in one of the Wednesday 3pm CP Conferences.  Residents are expected to critically appraise the article and assess its contribution to the existing literature.  Selected cases are also presented by the residents in the Texas Medical Center Wide Hematopathology Conferences.

 

Goals and Objectives of Rotation

A breakdown according to the six ACGME competencies is listed within the section “Goals and Objectives for Rotations Incorporating Hematopathology”.

 

The resident is to acquire knowledge for the practice of hematopathology and coagulation.  The resident is expected to acquire skills in procuring hematopoietic tissues, examining hematopoietic specimens/coagulation results, and rendering diagnoses, recommending further diagnostic studies and assisting in treatment decisions.  To accomplish this, the resident must acquire expertise in:

 

Hematopathology:

1        Evaluate the patient's clinical history and physical findings.

2        Perform bone marrow biopsies and aspirations

3        Prepare bone marrow specimens of high quality for examination.

4        Examine hematopathology specimens (peripheral blood smear, bone marrow aspirate and biopsy, lymph node), render diagnosis using additional techniques as needed, and give appropriate recommendations to the primary physician.

5        Skills in interpreting special studies: flow cytometry, immunoperoxidase stains.

6        Knowledge about treatments for various hematologic disorders.

7        Work closely with other consulting physicians to assist the primary physician in each patient's care.

8        Utilize nonscheduled time for review of case materials (hemepath study sets) filed in the Hematology sign-out room, as well as other tutorial materials.

9        Read hematology procedure manuals to be familiar with testing methodology and interpretation of hematology tests.

10    Quality control program in hematology.

 

Clinical microscopy:

1        Urinalysis (chemical and physiochemical tests; microscopy of urine sediment).

2        Pleural and peritoneal fluid/cerebrospinal fluid/synovial fluid.

 

Coagulation:

1        Read coagulation procedure manuals to learn methods of performing the tests for investigating patients with coagulation and platelet disorders.

2        Investigation of hemostatic disorders, using information obtained from laboratory tests and clinical information obtained directly from medical records or by consulting with patients' primary physicians.

3        Knowledge of clotting factors/inhibitors, their physicochemical properties, and their relationship to the rational use of blood components and other blood derivatives in coagulopathy.

4        Quality control program in hemostasis.

 

Graduated responsibilities by level of training:

Month 1: (a) learn the routine activities, (b) with help from senior residents and the attending, learn to complete interpretation drafts for clinical reports to be input into CERNER LIS, (c) complete learning objective topics for month 1 (see core curriculum)

 

Month 2: (a) help junior residents to review clinical cases and to complete interpretation drafts, (b) complete learning objective topics for month 2 (see core curriculum)

 

Month 3: (a) acting as attending to render preliminary diagnosis and to help junior residents to complete interpretation drafts, (b) work with the attending on laboratory issues such as QC/QA,  correlation studies, (c) complete learning objective topics for month 3 (see core curriculum)

Goals and Objectives for Rotations Incorporating Hematopathology

 

Research opportunities

The resident will have opportunities during this rotation to get exposure to research in hematopathology and coagulation.  The scholastic activities will be greatly beneficial to the resident in future clinical practice as well as for credentials in applying for fellowship and job positions.  Clinical cases of pathologic interests seen during the rotation can be written up as case reports for presentation in local/national pathology meetings as well as for publication in pathology journals.  More elaborate research experience may be explored by talking to the hematopathology staff.  This may require extra amount of time to be taken as Clinical Pathology electives.  Research activities must not take priority over clinical activities during the 3-month core rotation.
