Commentary: The Clinical Experience of a Junior Resident in Pediatric Neurosurgery and Introduction of the Resident Experience Score

Abstract The process of transforming a medical student to a competent neurosurgeon is becoming increasingly scrutinized and formalized. However, there are few data on resident workload. We sought to quantify the workload and educational experience of a junior resident while “on-call.” A single resident's on-call log was reviewed from the period of July 1, 2014 to June 30, 2016, corresponding to that resident's postgraduate years 2 and 3. For each patient encounter (ie, consult or admission), information pertaining to the patient's demographics, disease or reason for consult, date/time/location of consult, and need for any neurosurgical intervention within the first 24 hours was collected. In total, 1929 patients were seen in consultation. The majority of patients were male (62%) with a median age of 50 years (range, day of life 0-102 years) and had traumatic diagnoses (52%). The number of consults received during the 16:00 to 17:00 and 17:00 to 18:00 hours was +1.6 and +2.5 standard deviations above the mean, respectively. The busiest and slowest months were May and January, respectively. Neurosurgical intervention performed within the first 24 hours of consultation occurred in 330 (17.1%) patients: 221 (11.4%) major operations, 69 (3.6%) external ventricular drains, and 40 (2.1%) intracranial pressure monitors. This is the first study to quantify the workload and educational experience of a typical neurosurgical junior resident while “on-call” (ie, carrying the pager) for 2 consecutive years. It is our hope that these findings are considered by neurosurgical educators when refining resident education.

OBJECTIVE The authors previously demonstrated the use of a validated Objective Structured Assessment of Technical Skills (OSATS) tool for evaluating residents' operative skills in pediatric neurosurgery. However, no benchmarks have been established for specific pediatric procedures despite an increased need for meaningful assessments that can either allow for early intervention for underperforming trainees or allow for proficient residents to progress to conducting operations independently with more passive supervision. This validated methodology and tool for assessment of operative skills for common pediatric neurosurgical procedures—external ventricular drain (EVD) placement and shunt surgery— was applied to establish its procedure-based feasibility and reliability, and to document the effect of repetition on achieving surgical skill proficiency in pediatric EVD placement and shunt surgery. METHODS A procedure-based technical skills assessment for EVD placements and shunt surgeries in pediatric neurosurgery was established through the use of task analysis. The authors enrolled all residents from 3 training programs (Baylor College of Medicine, Houston Methodist Hospital, and University of Texas–Medical Branch) who rotated through pediatric neurosurgery at Texas Children's Hospital over a 26-month period. For each EVD placement or shunt procedure performed with a resident, the faculty and resident (for self-assessment) completed an evaluation form (OSATS) based on a 5-point Likert scale with 7 categories. Data forms were then grouped according to faculty versus resident (self) assessment, length of pediatric neurosurgery rotation, postgraduate year level, and date of evaluation (“beginning of rotation,” within 1 month of start date; “end of rotation,” within 1 month of completion date; or “middle of rotation”). Descriptive statistical analyses were performed with the commercially available SPSS statistical software package. A p value < 0.05 was considered statistically significant. RESULTS Five attending evaluators (including 2 fellows who acted as attending surgeons) completed 260 evaluations. Twenty house staff completed 269 evaluations for self-assessment. Evaluations were completed in 562 EVD and shunt procedures before the surgeons left the operating room. There were statistically significant differences (p < 0.05) between overall attending (mean 4.3) and junior resident (self; mean 3.6) assessments, and between overall attending (mean 4.8) and senior resident (self; mean 4.6) assessment scores on general performance and technical skills. The learning curves produced for the residents demonstrate a stereotypical U- or V-shaped curve for acquiring skills, with a significant improvement in overall scores at the end of the rotation compared with the beginning. The improvement for junior residents (Δ score = 0.5; p = 0.002) was larger than for senior residents (Δ score = 0.2; p = 0.018). CONCLUSIONS The OSATS is an effective assessment tool as part of a comprehensive evaluation of neurosurgery residents' performance for specific pediatric procedures. The authors observed a U-shaped learning curve, contradicting the idea that developing one's surgical technique and learning a procedure represents a monotonic, cumulative process of repetitions and improvement.
