Even the lower figure of 20% prevalence suggests that large numbers of people may be significantly affected by musculoskeletal pain. Neither KPT330 Borgsteede et al [30] or Smith et al [29] were specifically investigating musculoskeletal pain at the end of life and both papers reported that the levels of musculoskeletal pain were new findings that had not been highlighted in previous end of life care research. This emphasises the need for more population based epidemiological studies which specifically Inhibitors,research,lifescience,medical focus on

musculoskeletal symptoms. This is discussed further below. Impact The four case studies clearly demonstrated that musculoskeletal pain can significantly impact on individuals in diverse ways emphasizing the needs for individualised assessment and treatment of musculoskeletal pain at the end of life. However, as three of these studies Inhibitors,research,lifescience,medical describe particularly complex situations it is not possible to extrapolate any information about the impact of musculoskeletal pain to the general population. However the importance of the case histories as illustration is that they highlight that rational treatment targeted at comorbid musculoskeletal pain is a potentially important component of all patients in pain nearing the end of life: they powerfully challenge the assumption that pain in this period should simply be attributed to the condition causing death without

considering other concurrent explanations. Neither of the population Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical based studies discussed the impact or treatment of musculoskeletal pain. Treatment Only one of the case studies, Katz et al [26], argued that the treatment described; (total joint replacement), could offer a potent and systematic

treatment strategy in the palliative care of patients with advancing progressive disease and concomitant musculoskeletal Inhibitors,research,lifescience,medical pain. There was a dearth of studies about the treatments for musculoskeletal pain at the end of life in a primary care setting. This is an important omission because, although most people die in a hospital setting, the majority of the last year of life is lived in the community, either at home or within a care home [2,36]. A possible reason for the lack of information about treatment is that either the standard 4-Aminobutyrate aminotransferase tools advocated by palliative care, or the treatments advocated for chronic musculoskeletal pain, are effective. Palliative care promotes the use of the World Health Organisation cancer pain ladder [28] for systematic and effective pain management. Although there have been some studies that consider the effectiveness of this tool for cancer pain [37,38], there appears to be no study that considers whether this is an effective way to manage musculoskeletal pain at the end of life. There are, indeed, significant limitations in the evidence base for the use of opioids in chronic musculoskeletal pain [39-41] and the side effects of opiates meant they were ineffective in two of the case reports [25,27].
