Evans (2002) conducted a systematic review to investigate the impact of music therapy for the people in palliative care. The method undertaken for this study is the comprehensive search that was undertaken on the adult hospital patients in a randomized trial design. The measures such as anxiety, pain, mood of the patients and the vital signs were critically analyzed. Specific focus was given to the mood of the patients after invasive procedures and the impact of music. In this study, a total of 29 studies were combined of which there were 10 excluded, as they did not meet the criteria required. Participants of the study were made to play headphones to see if they reduce the impact of invasive procedures. It was determined that the music had an impact on normal procedures and they were able to maintain a positive morale. However, in the case of invasion procedures, the anxiety of the patients did not subside. There were a small reduction in the anxiety levels that was observed in some patients. They did not reduce the pain or change the morale of the patients. One positive factor was an overall improvement in the tolerance of the people.
