Just-in-Time Teaching (JiTT) Screencasts: a Randomized Controlled Trial of Asynchronous Learning on an Inpatient...

The efficacy of just-in-time teaching (JiTT) screencasts for graduate medical education on an inpatient adult hematology-oncology service (HOS) setting is not known. Our preceding pilot data identified six high-yield topics for this setting. The study objective was to evaluate screencast educational efficacy.

Internal medicine residents scheduled to start a rotation on the primary HOS of an academic medical center were eligible for this parallel, unblinded, randomized controlled trial with concealed allocation. Participants underwent block randomization to the usual educational curriculum either with or without access to a series of novel screencasts; all participants received an anonymous online end-of-rotation survey and a $20 gift certificate upon completion. The primary outcome was the change in attitude among learners, measured as their self-reported confidence for managing the clinical topics.

From 12/9/2019 through 6/15/2020, accrual was completed with 67 of 78 eligible residents (86%) enrolled and randomized. Analysis was by intention-to-treat and participant response rate was 91%. Sixty-four percent of residents in the treatment arm rated their clinical management comfort level as "comfortable" or "very comfortable" versus 21% of residents in the usual education arm (p = 0.001), estimated difference = 43% (95% CI: 21-66%), using a prespecified cumulative cutoff score. Treatment arm participants reported that the screencasts improved medical oncology knowledge base (100%), would improve their care for cancer patients (92%), and had an enjoyable format (96%).

Residents on a busy inpatient HOS found that a JiTT screencast increased clinical comfort level in the management of HOS-specific patient problems.
