I am utilizing Transitions Theory as the framework for my dissertation related to outcomes after lung transplantation. I have been through the literature pretty thoroughly and do not recall any citations for this particular topic. I know that there is no mention of this type of transition in Meleis's book. (Transitions Theory: Middle range and situation specific theories in nursing research and practice).
I did find this citation below. I don't have access to full text for this article to tell if transitions theory is utilized as a framework. It might be worth a look, though.
