The Patient Concerns Inventory in head and neck oncology: a structured review of its development, validation and clinical implications

INTRODUCTION: The Patient Concerns Inventory (PCI) is a condition specific prompt list that was initially developed for head and neck cancer (HNC) and is referred to as the PCI–HN. There have been numerous publications regarding the PCI–HN, since it was first published in 2009. To date, there has not been a review of its development, validation and clinical implications. A collation of relevant papers into key sections allows multidisciplinary teams and researchers to have an overview of the PCI–HN’s background, evaluation and utility. This is essential if colleagues are to have confidence in the tool and be able to reflect on how to optimise its use in clinical practice. METHODS: Five search engines were used: EMBASE, Medline, PubMed, CINAHL and Handle-on-QOL for the specific term ‘Patient Concerns Inventory’ up to and including 1st February 2022. In addition, an accumulation of PCI–HN data of 507 HNC patients was drawn from previous studies in Liverpool and Leeds between 2007 and 2020 and was analysed specifically for this paper. RESULTS: 54 papers relating to the PCI–HN were identified. The review is structured into eight sections: (1) What is the PCI–HN and how does it work; (2) Feasibility and acceptability; (3) Psychometrics; (4) Items selected and frequency (5) Associations with Health-Related Quality of Life (HRQOL) and casemix; (6) Other observational studies; (7) Randomised trial evaluation; (8) General discussion and further research. CONCLUSIONS: As the term PCI is quite ubiquitous and produces many hits when searching the literature, this review provides a very concise and convenient historical context for the PCI–HN and collates the current literature.
