Investigating the challenges and barriers of palliative care delivery in Iran and the World: A systematic review study.

Palliative care and terminal patients care centers have an important role in improving the physical and psychological state of the patient and their families and increasing their satisfaction and care providers. A literature search of online databases (PubMed, Scopus, Web of science, Cochrane library, and Google Scholar) was searched from January 1, 2000, to the end of April 2019, by using the appropriate English keywords. Furthermore, IranMedex, Barkat, and Magiran databases were searched for the Persian articles. We used Standards for Reporting Qualitative Research checklist to evaluate the articles quality. From 1328 articles, 166 were reviewed in depth with 13 satisfying our inclusion criteria. The findings of this study revealed a wide range of barriers and challenges to palliative care delivery. The identified barriers were: Cultural, social and organizational barriers, lack of resources, equipment and financing, attitudes and cultures, barriers related to the patient and the patient's family, related barriers providers, time and money, education, communication challenges, policies, insurance problems, safety, and crisis management. The results of the studies showed that there are various barriers and challenges such as economic, cultural, social, organizational, and communication related to palliative care. Given the identified barriers and challenges, it is suggested that to improve the delivery of palliative care, the health system policy-makers and planners consider a resource-appropriate and culturally appropriate framework for palliative care delivery.
