BACKGROUND: Person-centred palliative healthcare is an important approach to maintaining and improving patients' quality of life living with a chronic non-communicable disease and their partners. Such an approach can reduce unnecessary hospitalisation, holistically address the patient and their partners' needs, and help develop an advance care plan. OBJECTIVES: Assess, analyse, and synthesise the currently existing international guidelines for providing person-centred palliative care and identify the key components for providing a high-quality approach. METHODS: An umbrella review methodology of systematic reviews with the method of examination, analysis and synthesis of literature and the compilation method. Relevant systematic reviews of guidelines for providing person-centred palliative care in English, German and/or Slovenian language in PubMed, CINAHL, Web of Science and Cochrane Library databases, until November 2020. RESULTS: Out of 3,910 records, we included seven reviews for thematic synthesis. We identified four key elements of flourishing in person-centred palliative healthcare: (i) Healthcare staff prerequisites and traits; (ii) Palliative healthcare environment; (iii) Palliative healthcare processes; and (iv) Palliative healthcare outcomes. CONCLUSIONS: We concluded that person-centred palliative healthcare plays an important role in the comprehensive treatment of patients living with a non-communicable disease accompanied by disturbing symptoms. Therefore, it is necessary to raise awareness amongst healthcare professionals and especially general practitioners about the possibilities of including patients with a non-communicable disease in early person-centred palliative healthcare.
