Background: Palliative care is an interdisciplinary medical approach for people with illnesses that are unresponsive to curative treatment. Music therapy has been gaining ground in this field since the 1970s, with a not-always-standardized range of interventions and musical techniques.
Objective: The purpose of this systematic review is to analyze interventions with music therapy and new developments in this area in the field of palliative care.
Methods: The primary source of data for this review was the online database Web of Science (WOS). We also used other databases such as Medline and Scopus. A systematic search was performed of the past 6 years following the PRISMA criteria.
Results: From a selection of 310 documents, we reviewed 54 completed articles and included 19 studies in the review. The percentage of agreement in the selection of articles was 87.5% and the Cohen Kappa index of inter-rater reliability was 0.727. In 5 of the articles, the musical interventions were not specified. However, in the remaining 14 they were, including new developments such as use of the monochord and the body tambura, and adaptation of the RBL (Rhythm, Breath & Lullaby) method.
Conclusions: There has been notable improvement in the specification of musical interventions during music therapy sessions in palliative care. However, articles in this field need to describe how these techniques are carried out and any new developments. All this without forgetting that the patient's musical preferences are a fundamental aspect when performing music therapy sessions.
