RESUMEN
BACKGROUND: Palliative care (PC) is oriented to improving the quality of life of patients and their families who are facing problems associated with life-threatening illness. It is a continuously changing and evolving field. Although it is a universal right, there are many barriers to addressing the unmet need for PC, affecting both patient and family as well as health care professionals (HCP). Many studies have highlighted the unmet needs of patients and caregivers, but it is also necessary to understand the needs of HCP in order to better develop PC. It is therefore necessary to identify all those barriers and unmet needs in order to develop and guarantee universal quality PC. METHODS: Bibliography search in relevant databases (PubMed, Cochrane Library, Trip Database) of documents published between 2018 and 2022, both included, written in English or Spanish. Key words-MeSH terms: Palliative Care, Palliative Medicine, Health Personnel, Continuing Education, Health Care Providers; and free text: healthcare professionals, continuous learning, training needs, gap, unmet needs, nursing. Articles about children or teenagers were excluded, as those related to the coronavirus disease 2019 (COVID-19) pandemic. RESULTS: A grand total of 1,150 documents were located and 20 were found through other sources. Additionally, 3 documents were found and kept despite not being included in the timeline previously discussed due to its relevance. Only 20 were finally included in this review. The identified unmet needs throughout the PC continuum have been categorized in three groups: diagnosis/recognition of the patient entering the PC continuum; end-of-life (EoL); and bereavement. Facilitators in PC have been identified in each category. CONCLUSIONS: Given the challenging nature of PC and the lack of knowledge throughout the continuum, addressing the challenges identified may result in meaningful and long-lasting results for both HCP and the patient-family unit. Training would be the answer to most of the unmet needs detected.
