Effectiveness of palliative care interventions offering social support to people with life-limiting illness-A systematic review.

Individuals managing the challenges of life-limiting illness require adequate social support to maintain quality of life. Qualitative research reports that patients value highly the social support obtained in palliative care interventions such as day care and group therapies. This systematic review aims to summarise existing quantitative evidence on palliative care interventions that facilitate social support. Research literature was systematically searched using electronic databases and key journals. Searches returned a total of 6,247 unique titles of which sixteen were eligible for inclusion. Interventions include group therapies, group practical interventions and palliative day care. Outcome measures and study designs were heterogeneous. Only one study used a validated outcome measure of social support. Benefits were influenced by participant characteristics such as baseline distress. Partial economic evaluation was attempted by two studies. Methodological challenges include attrition and use of outcome measures that were insensitive to change. Statistically significant results were reported in psychological and physical domains. Evidence is limited due to methodological issues and a scarcity of quantitative research, particularly regarding long-term benefits and cost-effectiveness. Interventions may be more beneficial to some groups than others.

The effectiveness and cost-effectiveness of acupressure for the control and management of chemotherapy-related acute and delayed nausea: Assessment of Nausea in Chemotherapy Research (ANCHoR), a randomised controlled trial.

BACKGROUND: Chemotherapy-induced nausea and vomiting remain difficult symptoms to manage in clinical practice. As standard antiemetic drugs do not fully eliminate these symptoms, it is important to explore the adjuvant role of non-pharmacological and complementary therapies in antiemetic management approaches. Acupressure is one such treatment showing highly suggestive evidence so far of a positive effect, meriting further investigation. OBJECTIVES: The primary objective was to assess the effectiveness and cost-effectiveness of self-acupressure using wristbands compared with sham acupressure wristbands and standard care alone in the management of chemotherapy-induced nausea. Secondary objectives included assessment of the effectiveness and cost-effectiveness of the wristbands in relation to vomiting and quality of life and exploration of any age, gender and emetogenic risk effects. DESIGN: Randomised three-arm sham-controlled trial (Assessment of Nausea in Chemotherapy Research or ANCHoR) with an economic evaluation. Arms include the wristband arm, the sham wristband arm and the standard care only arm. Randomisation consisted of minimisation with a random element balancing for gender, age (16-24, > 24-50, >50 years) and three levels of emetogenic chemotherapy (low, moderate and high). Qualitative interviews were incorporated to shed more light on the quantitative findings. SETTING: Outpatient chemotherapy clinics in three regions in the UK involving 14 different cancer units/centres. PARTICIPANTS: Chemotherapy-naive cancer patients receiving chemotherapy of low, moderate and high emetogenic risk. INTERVENTION: The intervention was acupressure wristbands pressing the P6 point (anterior surface of the forearm). MAIN OUTCOME MEASURES: The Rhodes Index for Nausea/Vomiting, the Multinational Association of Supportive Care in Cancer (MASCC) Antiemesis Tool and the Functional Assessment of Cancer Therapy - General (FACT-G). At baseline participants completed measures of anxiety/depression, nausea/vomiting expectation and expectations from using the wristbands. RESULTS: In total, 500 patients were randomised in the study arms (166 standard care, 166 sham acupressure and 168 acupressure) and data were available for 361 participants for the primary outcome. The primary outcome analysis (nausea in cycle 1) revealed no statistically significant differences between the three arms, although the median nausea experience in patients using wristbands (both real and sham ones) was somewhat lower than that in the antiemetics only group (median nausea experience scores for the four cycles: standard care arm 1.43, 1.71, 1.14, 1.14; sham acupressure arm 0.57, 0.71, 0.71, 0.43; acupressure arm 1.00, 0.93, 0.43, 0). A gender effect was evident (p= 0.002), with women responding more favourably to the use of sham acupressure wristbands than men (odds ratio 0.35 for men and 2.02 for women in the sham acupressure group; 1.27 for men and 1.17 for women in the acupressure group). This suggests a placebo effect. No significant differences were detected in relation to vomiting outcomes, anxiety and quality of life. Some transient adverse effects were reported, including tightness in the area of the wristbands, feeling uncomfortable when wearing them and minor swelling in the wristband area (n= 6).There were no statistically significant cost differences associated with the use of real acupressure bands (£70.66 for the acupressure group, £111.13 for the standard care group and £161.92 for the sham acupressure group). In total, 26 subjects took part in qualitative interviews. The qualitative data suggested that participants perceived the wristbands (both real and sham) as effective and helpful in managing their nausea during chemotherapy. CONCLUSIONS: There were no statistically significant differences between the three arms in terms of nausea, vomiting and quality of life, although apparent resource use was less in both the real acupressure arm and the sham acupressure arm compared with standard care only; therefore; no clear conclusions can be drawn about the use of acupressure wristbands in the management of chemotherapy-related nausea and vomiting. However, the study provided encouraging evidence in relation to an improved nausea experience and some indications of possible cost savings to warrant further consideration of acupressure both in practice and in further clinical trials.

Palliative care for dementia--time to think again?

It is estimated that there are 35.6 million people with dementia worldwide and this is projected to increase to over 115 million by the year 2050. Dementia is a progressive neurodegenerative disease that significantly reduces survival. End-of-life care received by this group is often poor and does not equate to that offered in other life limiting illnesses. This review highlights results from a large UK study of informal carers of people with dementia to explore what are determinants of care for people with dementia and their family carers. New perspectives as to models of care for end-of-life care for patients with dementia are discussed together with how these may be implemented and delivered within wider community settings and contexts, where many people with dementia may be cared for in the future.

Revisiting depression in palliative care settings: the need to focus on clinical utility over validity.

OBJECTIVE: To review the literature on depression in palliative care patients to identify implications for development of clinical practice and individual patient care. METHOD: A qualitative review of depression prevalence studies in palliative care settings. We explore the utility of existing prevalence studies for clinical practice through testing two hypotheses: that high prevalence rates are associated with increased risk factors in study samples, and that poor methodological quality of the studies artefactually inflate prevalence estimates. Eighteen studies were identified in the search and included in this review. RESULTS: Risk factors may contribute to depression prevalence but through a complex interaction of factors making individual risk levels hard to determine. Measurement artefact cannot, alone, account for elevated levels of depression in this population but may contribute to imprecision. The importance of organic decline as a potential confounding variable is highlighted. CONCLUSION: Future research into the causes and prevalence of depression should adopt longitudinal approaches using large samples, and consider the impact of organic disorder as an important confounding factor. Clinical practice and care of individual patients may be better supported by development of a prognostic index considering the predictive power of depressive symptoms and risk factors on well-being.

When health information systems fail.

The failure of health care information systems is a topic of critical importance for information management professionals. Such failure is also important for the consumers of health services who rely on the informed activity of health care workers for their well-being. This article presents case studies of two information systems projects within the British National Health Service that are generally viewed as having failed. The article provides an analysis of these failures, and examines whether the British National Health Service is particularly prone to the phenomenon of information systems failure.
