Patients who qualify for liver transplantation experience a variety of pre- and postoperative complications that impact their ability to access and participate in life’s activities at home and in the community. Physical therapists (PTs) are uniquely trained to assist with restoring participation in these activities by examining patients, evaluating findings, and establishing treatment interventions to maximize access, participation and functional ability, even in patients who are experiencing declining health. Yet, there is little evidence in the literature regarding PT involvement with liver transplant patients. This study will examine the current role of PTs in treating these patients and establish a middle range theory to guide future clinical practice, research, advocacy and education related to PT involvement in the care of patients undergoing liver transplantation. We will recruit PTs who have routinely treated patients of this population on an ancillary basis as well as any who have served as members of core, interdisciplinary transplant teams. Other team members who are routinely involved in the pre- to postoperative care of this population, including surgeons, gastroenterologists, oncologists, nurse practitioners, and primary nurse coordinators, will also be recruited to participate in the study. Global MAX© software, developed by Concept Systems, Inc. will guide collection of qualitative and quantitative data, analysis and interpretation of results. The outcome anticipated is a middle range theory to guide clinical practice, research, advocacy and education related to the involvement of PTs as core members of the interdisciplinary teams who oversee the care of patients undergoing liver transplantation.
