Clinical experience suggests that many symptoms occur together. In this paper, we examine the rationale and evidence base for symptom clusters in different medical fields, particularly the cluster phenomenon in cancer. Cancer symptom clusters are a reality. ⋯ Discrepancies between clinically defined and statistically obtained clusters raise important questions. We must consider the analytical techniques used, and how methodology might influence cluster occurrence and composition. Further research is warranted to establish universally accepted statistical methods and assessment tools for symptom cluster research.

The impact of opioids, anticholinergic medications and disease progression on the prescription of laxatives in hospitalized palliative care patients: a retrospective analysis.
Definitive risk factors for constipation in palliative care remain poorly defined. A retrospective analysis of 211 admissions to a palliative care unit was undertaken, with the main aim being to identify some factors, which influence laxative prescription. On univariate analysis, significant unadjusted associations were found between two or more prescribed laxatives and a diagnosis of malignancy, morphine equivalent dose, type of illness phase and the subsequent phase type, length of phase, anticholinergic load imposed by medications, symptom severity and functional status. ⋯ Two additional measures of function, toileting (OR 3.6, 95% CI = 1.6-8.2) and transfer (OR 0.4 95% CI = 0.2-0.9), also became significant. Total anticholinergic load was significantly associated with the prescription of a single laxative (OR 1.4, 95% CI = 1.0-2.0) and two or more laxatives (OR 1.8, 95% CI = 1.3-2.5) for each unit increase in anticholinergic load. Opioids and in particular opioids prescribed at higher doses, the total anticholinergic load associated with prescribed medications, the degree of impaired physical function of a person, their length of stay in a palliative care unit and their proximity to death were all strongly related to the prescription of laxatives.

Randomized Controlled Trial Multicenter StudySublingual administration of fentanyl to cancer patients is an effective treatment for breakthrough pain: results from a randomized phase II study.
In this study we evaluated the efficacy and tolerability of sublingual fentanyl (SLF) for breakthrough pain (BTP) in adult opioid-tolerant cancer patients. Patients received one dose of placebo, SLF 100, 200 and 400 microg in random order at four pain episodes. The primary efficacy endpoint was pain intensity difference (PID) from baseline. ⋯ Reduced use of rescue medication (p < 0.001, SLF 400 microg) and improved global assessment of treatment (p = 0.0146, SLF 400 microg) confirmed these differences as clinically important. Nausea and dizziness were the most common treatment-related adverse effects. SLF appears to be a fast, effective and well-tolerated treatment for BTP.

Multicenter StudyHow do nurses assess and manage breakthrough pain in specialist palliative care inpatient units? A multicentre study.
The aim of this qualitative study was to gain a better understanding of how nurses working on inpatient specialist palliative care units assess and manage breakthrough pain. Thematic analysis of semi-structured interviews with fifteen nurses from five different specialist palliative care units in the UK was undertaken. ⋯ Nurses had difficulty defining breakthrough pain as a distinct pain subtype and were often unable to differentiate it from poorly controlled background pain. This study highlights significant training needs and suggests that the theoretical work and recently published consensus recommendations around breakthrough pain now need to be translated into day-to-day clinical practice.
