Pediatric and Perinatal Pathology Rotation Duration

Training in pediatric and perinatal pathology takes place throughout the AP curriculum, which is spread over years one, three and four. Residents receive specific pediatric and perinatal pathology instruction in each of the three components which make up the AP core. The total pediatric and perinatal pathology experience encompasses approximately 62 weeks of the 144-week AP curriculum.

Surgical Pathology and Frozen Sections: residents gross and sign-out pediatric and perinatal specimens one of every two days spent on this rotation. Pediatric and perinatal specimens consist of 15-20 percent of all surgical accessions at our hospital. Residents participate in the preparation and analysis of all pediatric intraoperative consultations (approximately five to 10 a week).

Residents are encouraged to become involved in the ongoing clinical and basic research projects of the pediatric and perinatal pathology staff and their collaborators from both the clinical and basic science departments of the hospital and medical school. Dedicated time may be devoted to projects during the third and fourth-year electives block.


Duties and Responsibilities of Residents by Year

Residents are initially trained by being paired with an experienced resident and then assume independence for their own cases. Residents assume graded responsibility, first as apprentices, then as practitioners and then as teachers and supervisors.

First-Year Residents

First-year residents are encouraged to concentrate on technical skills and to collaboratively sign their cases with the attending pathologists. Residents should be aware that pediatric and perinatal autopsy procedures differ in many ways from those used for adult autopsies. Special concerns, procedures and differential diagnoses differ with the age of the patient. The first-year resident should develop an appropriate approach to the fetal, newborn and child categories.

Senior (PGY3, PGY4) Residents

Senior residents are expected to bring autopsy cases for sign-out in essentially complete form, ready for approval by the attending pathologist. Autopsy techniques for patients of different ages should be mastered.

Resident Supervision and Evaluation

Each pediatric pathologist evaluates residents in the following manner:

Daily

Evaluation of medical knowledge and practice-based learning and improvement occurs at the time of microscopic sign-out in surgical pathology, formulation of the preliminary and final anatomic diagnoses in autopsy pathology, and performance and interpretation of frozen sections at the time of intraoperative consultation.

Evidence of progress in utilizing a systems-based approach to pathology practice is assessed by review of the resident's handling of specimens, interaction with the clinical staff and preparation of surgical and autopsy reports.

Monthly

Formal online evaluations of each resident (MyEvaluations system) addressing the following criteria:

  • Interpersonal and communication skills
  • Medical knowledge
  • Patient care
  • Practice-based learning and improvement
  • Professionalism
  • Research and scholarly activities
  • System-based practice

Yearly

Each resident's performance on the annual in-service examination is reviewed in detail.

Ad Hoc

Each resident will critique and modify case presentations and research projects.
