BACKGROUND:
According to the 2017 American College of Gastroenterology (AGA) guidelines, therapeutic drug monitoring (TDM) of drug trough concentrations and anti-drug antibodies is recommended to optimize treatment with anti-tumor necrosis factor (TNF) agents and thiopurines1. Specifically, the AGA conditionally recommends reactive TDM in patients with active symptoms of inflammatory bowel disease (IBD) while on anti-TNF agents, as such testing is crucial for differentiating between mechanistic, non-immune mediated pharmacokinetic and immune-mediated pharmacokinetic drug failure, and allows providers to appropriately tailor treatment regimens. As such algorithms for monitoring therapies in IBD have evolved, it has become incumbent on physicians caring for these patients to develop techniques to engage in patient-centered care using the technique of shared decision making. Gastroenterology (GI) trainees may not be well versed in navigating these complex interpersonal skills. The Observed Structured Clinical Examination (OSCE) is a well-validated method of assessing core competencies of communication and professionalism. While it is traditionally used at the undergraduate medical education level, it has been used at the graduate level to address disease-specific competencies. Here, we discuss the use of an OSCE to assess the performance of GI fellows in engaging in shared decision-making on the topic of TDM for a patient with complex IBD refractory to treatment.

METHODS:
Eleven second-year gastroenterology fellows from 4 GI fellowship programs participated in a 4 station OSCE. Previously validated OSCE checklists were used to assess the fellows' performance in IBD-specific cases, one of which will be discussed here. In the “Therapeutic Drug Monitoring” case, the objective for the fellows was to discuss the indications for infliximab trough and antibody testing and how results of this testing would impact treatment based on the AGA guidelines. Checklists were scored on a 3 and 5-point Likert Scale by the Standardized Patient (SP), mapped to the appropriate ACGME milestones by a GI medical educator and normalized on a scale from 0 to 9. Post-OSCE, the fellows were surveyed to assess their perspective on their performance as well as the exam's educational value.

RESULTS:
6 ACGME milestones were assessed in this OSCE. Scores ranged from mean of 5.85 to 7.88. Fellows scored lowest on gathering and synthesizing essential and accurate information to define each patient's clinical problem(s) (PC1, mean score 5.85) with an average score of 5.85. They scored highest for overall clinical knowledge (MK1, mean score 7.88). Overall, 9/10 (90%) of fellows would be recommended for their interpersonal skills, but only 4/10 (40%) were deemed effective in their communication skills. The majority of fellows noted improvement in their understanding of when to use and how to interpret TDM after the exercise.

CONCLUSION(S):
This OSCE was designed to assess clinical and communication skills for gastroenterology surrounding the complex clinical arena of therapeutic drug monitoring utilizing crucial communication skills. The results suggest weaker performance linked to gathering and synthesizing clinical information, with stronger performance in clinical knowledge, developing management plans and various communication skills. This OSCE feedback and assessment can be used to develop targeted educational interventions to strengthen clinical and communication skills for providers.
