番茄社区app Objective Assessment of Skills in Surgery (番茄社区app OASIS)

番茄社区app Objective Assessment of Skills in Surgery (番茄社区app OASIS)

What Is 番茄社区app OASIS?

The American College of Surgeons Objective Assessment of Skills in Surgery (番茄社区app OASIS) is a formative assessment that can be used to identify areas of strength and areas for improvement in selected technical skills of junior-level surgical trainees (PGY-2). 番茄社区app OASIS uses simulation-based, time-limited stations with faculty assessors to measure resident performance on a series of technical tasks essential for surgical practice. Significantly, the 番茄社区app OASIS results will support surgical trainees, surgical educators, and program directors in tailoring learning activities to address individual and group needs in the competency-based education and training era.

Mohsen M., Shabahang, MD, PhD, F番茄社区app, gives an introduction to the 番茄社区app OASIS.

番茄社区app OASIS offers the following features:

  • Individualized feedback regarding trainee performance at each station
  • Benchmarking data for comparing residents across participating programs
  • Detailed instructions for administering the assessment within surgical residency programs

番茄社区app OASIS includes a comprehensive set of resources: psychometrically tested rater checklists, standardized instructional videos, model instructions, objectives and stems. Furthermore, the assessment tool offers step-by-step model-building instructions with a list of required materials.

Eight Simulation Stations

  • Lipoma
  • Laparoscopic Appendectomy
  • Laparotomy
  • Laparoscopic Cholecystectomy
  • Ultrasound Guided Central Line Access
  • Trocar Veress Needle Insertion
  • Repair of Enterotomy
  • Chest Tube Placement

Assessment Psychometrics

Yoon Soo Park, PhD, provides background on the psychometric properties of the 番茄社区app OASIS.

Development and Authors

In 2017, the American College of Surgeons Division of Education formed the 番茄社区app Committee on Objective Assessment of Skills in Surgery, consisting of seasoned surgical educators actively involved in residency programs and community-based settings across North America. Dr. Ajit K. Sachdeva and Dr. Mohsen M. Shabahang co-chaired the committee, working with the members to conceptualize and implement 番茄社区app OASIS. The primary goal of the Committee was clear: to create low-cost, simulated, reproducible, and objective assessment tools for surgical trainees in selected competency domains. Committee members established to identify eight stations, focusing on the essential technical skills that junior-level residents or surgical trainees should learn and master by the end of PGY2.

The 番茄社区app OASIS was pre-piloted to establish feasibility and to gather information regarding implementation at two sites. Following the pre-pilot, rater checklists, model instructions, and evaluation forms were refined based on feedback from faculty assessors and surgical trainees. 番茄社区app OASIS was piloted from 2021-2023 at several sites. Psychometric results indicated high discrimination between low and high-performing trainees, and acceptable inter-rater and inter-station reliability.

Frequently Asked Questions

Complete the form below to request more information:

Process

  1. The participating program completes the enrollment application.
  2. The program completes the payment.
  3. The program is granted access to the 番茄社区app OASIS materials.
  4. The program prepares the 番茄社区app OASIS stations by acquiring model materials and building the models. Creating models may take longer in some institutions.
  5. The program conducts the assessments of its PGY-2 residents.
  6. The program administrator enters the resident assessment data into the 番茄社区app database for benchmarking learner performance.
  7. The 番茄社区app sends learner and program performance benchmark comparison data to the program director.

Confidential Results and Reports

Resident assessment data submission to the 番茄社区app will use unique participant codes with no identifiable information. Only the participating residency programs have the name-code matching table. The resident assessment data collected from multiple programs will be used to create an aggregated data set for nationwide benchmark comparison.

Following the assessments and submission of the data, program directors will receive confidential reports with data on the technical skills performance of their residents. Results list each surgical skills station, as well as the overall distribution of scores on the assessment with respect to the residency program and national benchmarks. These reports will allow program directors and each resident to recognize specific strengths and to develop learning plans to address focused areas for improvement.
