The interval during which the managing organization assumes the defined responsibility

Comments
My understanding is that the episodeOfCare is solely a single organization's tracking of an episode. We should make sure that the standard is clear regarding this vs. multiple organizations managing a condition (or set of conditions) for a patient. If the intent is to try to make a standard for how multiple organizations can track periods of responsibility within a patient's episode of care, then I think the design needs much more discussion.

Otherwise, I think that "period" should be noted simply as tracking the start and end date as it is known to the organization.
