Pain is subjective, warranting tailored responses in pharmacotherapy and nursing support. Despite this, the evidence for suitable nursing support for pain is not well established in terminally ill patients such as those with cancer; therefore, it is necessary to provide support in consideration of changes in physical symptoms and quality of life. However, interventional studies for such patients are often difficult. There have been no comprehensive studies to date on non-pharmacological support that can be implemented by nurses. Therefore, with the aim of examining nursing support applicable at the end of life, this scoping review comprehensively mapped nursing support for pain in cancer patients at all stages of the disease. This study complies with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and the Arksey and O'Malley framework. All available published articles from the time of database establishment to January 31, 2022, were systematically searched for in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), CENTRAL, and the Ichushi Web database of the Japanese Society of Medical Abstracts. Overall, 10,385 articles were screened, and 72 were finally included. Both randomized controlled trials (RCTs) (n = 62) and non-RCTs (n = 10) were included. Twenty-two types of nursing support were identified. Eighteen of them showed positive results; five of them were provided only to terminally ill patients, three of which were effective, namely, comfort care, foot bath, and combined therapy. It is important to examine the applicability of types of nursing support in clinical practice in the future.
