Supervision Models in Training Environments

Attending physicians often supervise novice junior residents in a direct one-to-one format. Alternatively, a senior resident can be paired with a new trainee under the non-direct (but immediately available) supervision of an attending physician. Resident supervision has been considered an important step towards independent practice. Both models are ubiquitous in the United States, but no study to date has been performed if one model is better than the other with respect to supervision scores.
