Abstract: Psychiatric consultation liaison (PCL) nursing is an evolving specialist area of mental health nursing in the USA, UK, Australia and New Zealand. The aim of this dissertation is to explore models of PCL nursing practice in order to develop and discuss a PCL nursing model applicable to the New Zealand context. The role of the PCL nurse was of particular interest to the author as a new practitioner in this specialist area. While there have been PCL nurses in practice for over 50 years, the literature does not offer much clarity about models of PCL nursing. From a review of the literature, four themes were recurrent in the work of PCL nurses. These themes represent four functions which are vital to the role of the PCL nurse: partnership, expertise of the PCL nurse, therapeutic relationship and organisational consultation. The needs of the patient are the core of this model and the primary objective is to improve the quality of care of patients in the general hospital with co-existing physical and psychological problems. It is imperative that PCL nurses evaluate their practice and embark on research to investigate clinical outcomes, cost effectiveness and the impact of PCL nurse practice on patients and staff. This PCL nursing model provides a beginning for this process. It also clarifies and articulates the role of the PCL nurse which enables the service to be promoted to colleagues. This PCL nursing model represents a critique of the author's understanding of the role of the PCL nurse. As expertise develops, the model will continue to be tested and refined.
