Kennedy terminal ulcer and other skin wounds at the end of life: An integrative review

Abstract

Aims: To undertake an integrative literature review to identify, analyse and synthesize current literature on the Kennedy terminal ulcer (KTU) and other unavoidable skin injuries that appear at the end of life regardless of the healthcare context in which they occur.

Methods: Integrative review following the Whittemore and Knafl methodology. The search was carried out in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Scopus. It was limited to articles in English, French, Portuguese and Spanish. As there is little scientific production on the subject, no restrictions were applied regarding publication date.

Results: Only 17 articles met the inclusion criteria. These articles were reviewed and analysed. Four relevant issues emerged: Skin failure, SCALE, Kennedy Terminal Ulcer, Trombley-Brennan: different names for the same problem; the defining characteristics and physiopathology of KTU; the differences between KTU and other injuries; and the care approach for KTU and other unavoidable injuries at the end of life.

Conclusions: We identified gaps regarding the physiopathology of KTU since the current knowledge is based only on hypotheses. There is also a large gap in the knowledge about care approaches, perhaps because care plans are not recorded. Despite this, it is clear that the main objective in this situation at the end of life would be to prioritize patient comfort and quality of life.
