Current State of Palliative Care in Iran and Related Issues: A Narrative Review

Palliative research studies seem to be limited and disperse in Iran. The present study was therefore conducted to review and categorize the Palliative Care (PC) studies performed in Iran in terms of the research type, the type/focus of PC, the measured outcomes in interventional palliative studies and their related results, the disease type, and their geographical distribution.

This narrative review was conducted in 2021 in which both Iranian and international databases including PubMed, Scopus, Web of science, CINAHL, ProQuest, Magiran, SID, Noormags, ISC were searched. The inclusion criteria were original articles conducted in Iran and results published in Persian or English journals ab initio in which PC was assessed as a variable (dependent or independent) or the main concept.

A total of 1096 articles were identified from which only 44 articles were reviewed. The research studies were mainly focused on cancer and majority conducted in Tehran. Majority of studies were quantitative-interventional leading to a variety of positive changes in dependent variables, including reduce in pain severity, change in life pattern, a good response to therapy, increase life expectancy, improve in dysphagia, improve quality of life, reduce patients' metastasis, and increase in nurses' self-efficacy.

The PC studies distributed across different fields and cities in Iran resulted to a number of positive outcomes for patients. More focused and robust research studies with different patients need to be conducted in this emerging field in Iran.
