The Camden Coalition Care Management Program Improved Intermediate Care Coordination: A Randomized Controlled Trial.

When a randomized evaluation finds null results, it is important to understand why. We investigated two very different explanations for the finding from a randomized evaluation that the Camden Coalition's influential care management program-which targeted high-use, high-need patients in Camden, New Jersey-did not reduce hospital readmissions. One explanation is that the program's underlying theory of change was not right, meaning that intensive care coordination may have been insufficient to change patient outcomes.
