Coleman, E. The CTM-3 and CTM-15. The Care Transitions Program. Http://www.caretransitions.org/ctm_main.asp. Accessed 7/9/14. We have created two versions of the CTM®. The CTM-15® is a comprehensive version designed for those programs that focus explicitly on measuring care transitions. Alternatively, the CTM-3® is a more concise measure (and a subset of the CTM-15®) designed for those programs that focus on care transitions either alone or in addition to other aspects of care and can only employ a limited number of items. Both measures have been rigorously developed and have been shown to predict return to the hospital and/or emergency department and discriminate among hospitals known to differ in performance in this area. Three question patient survey.
