Palliative care assessment of dry mouth: what matters most to patients with advanced disease?

PURPOSE: Dry mouth is a highly prevalent and significant symptom in patients with advanced progressive diseases. It is a poorly understood area of research, and currently, there is no standardised outcome measure or assessment tool for dry mouth. METHODS: To assess responses to self-reported dry mouth questions, the impact of dry mouth, methods used to reduce symptoms and relevance of the questionnaire. A cross-sectional multisite study of 135 patients with advanced progressive disease experiencing dry mouth. Participants were located in the inpatient, day care, outpatient or community setting. RESULTS: The majority (84.4%) of patients rated their dry mouth as moderate or severe using the verbal rating scale (VRS). Seventy-five percent (74.7%) had a numeric rating scale (NRS) score of 6 or more for dry mouth severity. Patients reported that dry mouth interfered most with talking and was the most important function to assess (median score 6 out of 10) followed by eating (median 5) and taste (median 5). Taking sips of drink was the most common and most effective self-management strategy. Over half of patients (54.6%) also reported impact on swallow and sleep and associated dryness of lips, throat and nasal passages. CONCLUSIONS: This study highlights the severity of dry mouth in advanced disease. Important factors when assessing patients with dry mouth should include the functional impact on day-to-day activities including talking, dysphagia and sleep. Simple considerations for patients include provision of drinks and reviewing medications. This study could be used to develop a standardised assessment tool for dry mouth to use in clinical practice.

Pharmacist educational interventions for cancer pain management: a systematic review and meta-analysis.

OBJECTIVES: Educational interventions by pharmacists for patients with cancer pain aim to improve pain management, but little is known about the different components of interventions and their effectiveness. Our aim was to assess the benefit of pharmacist delivered educational interventions for patients with cancer pain. A systematic review and meta-analysis of experimental trials testing pharmacist delivered educational interventions for cancer pain was carried out to identify the components of interventions and effectiveness at improving pain-related outcomes for patients with cancer. A literature review was conducted in EMBASE, MEDLINE, CINAHL, PsycINFO, ASSIA, Web of Science and CENTRAL from inception until January 2018 searching for educational interventions involving a pharmacist for patients with cancer pain. Four studies were included involving 944 patients. Meta-analysis was carried out where possible. KEY FINDINGS: Meta-analysis of three of the four studies found that mean pain intensity in the intervention group was reduced by 0.76 on a 0-10 scale (95% confidence interval), although only two of the studies used validated measures of pain. Improvements in knowledge, side effects and patient satisfaction were seen although with less reliable measures. SUMMARY: Pharmacist educational interventions for patients with cancer pain have been found to show promise in reducing pain intensity. Studies were few and of varying quality. Further, good quality studies should be carried out in this area and these should be comprehensively reported. Trials measuring patient self-efficacy and patient satisfaction are needed before the impact of the pharmacist delivered interventions on these outcomes can be established.

Access to hospital and community palliative care for patients with advanced cancer: A longitudinal population analysis.

BACKGROUND: The UK National Health Service is striving to improve access to palliative care for patients with advanced cancer however limited information exists on the level of palliative care support currently provided in the UK. We aimed to establish the duration and intensity of palliative care received by patients with advanced cancer and identify which cancer patients are missing out. METHODS: Retrospective cancer registry, primary care and secondary care data were obtained and linked for 2474 patients who died of cancer between 2010 and 2012 within a large metropolitan UK city. Associations between the type, duration, and amount of palliative care by demographic characteristics, cancer type, and therapies received were assessed using Chi-squared, Mann-Whitney or Kruskal-Wallis tests. Multinomial multivariate logistic regression was used to assess the odds of receiving community and/or hospital palliative care compared to no palliative care by demographic characteristics, cancer type, and therapies received. RESULTS: Overall 64.6% of patients received palliative care. The average palliative care input was two contacts over six weeks. Community palliative care was associated with more palliative care events (p<0.001) for a longer duration (p<0.001). Patients were less likely to receive palliative care if they were: male (p = 0.002), aged 80 years or over (p<0.05), diagnosed with lung cancer (p<0.05), had not received an opioid prescription (p<0.001), or had not received chemotherapy (p<0.001). Patients given radiotherapy were more likely to receive community only palliative care compared to no palliative care (Odds Ratio = 1.49, 95% Confidence Interval = 1.16-1.90). CONCLUSION: Timely supportive care for cancer patients is advocated but these results suggest that older patients and those who do not receive anti-cancer treatment or opioid analgesics miss out. These patients should be targeted for assessment to identify unmet needs which could benefit from palliative care input.

Older age is associated with less cancer treatment: a longitudinal study of English cancer patients.

Background: making informed decisions about cancer care provision for older cancer patients can be challenging and complex. Evidence suggests cancer care varies by age, however the relationship between age and care experiences from diagnosis to death for cancer patients within the UK has not previously been examined in detail. Patients and methods: retrospective cohort linking cancer registry and secondary care data for 13,499 adult cancer patients who died between January 2005 and December 2011. Cancer therapies (chemotherapy, radiotherapy, surgery), hospital palliative care referrals, hospital admissions and place of death were compared between age groups using multivariable regression models. Trends in cancer care over time, overall and within age groups were also assessed. Results: compared with adult patients under 60 years, patients aged 80 years and over were less likely to receive chemotherapy, radiotherapy, a hospital palliative care referral; or be admitted to hospital but were more likely to die in a care home. Overall, the percentage of patients receiving chemotherapy, surgery, hospital palliative care referrals and hospital admissions have increased while deaths in hospital have decreased. Deaths at home have increased for patients aged 80 years and over. Conclusion: older patients are less likely to receive cancer therapies or hospital palliative care before death. Further research is needed to identify the extent to which these results reflect unmet need.

Is palliative care support associated with better quality end-of-life care indicators for patients with advanced cancer? A retrospective cohort study.

OBJECTIVES: This study aimed to establish the association between timing and provision of palliative care (PC) and quality of end-of-life care indicators in a population of patients dying of cancer. SETTING: This study uses linked cancer patient data from the National Cancer Registry, the electronic medical record system used in primary care (SystmOne) and the electronic medical record system used within a specialist regional cancer centre. The population resided in a single city in Northern England. PARTICIPANTS: Retrospective data from 2479 adult cancer decedents who died between January 2010 and February 2012 were registered with a primary care provider using the SystmOne electronic health record system, and cancer was certified as a cause of death, were included in the study. RESULTS: Linkage yielded data on 2479 cancer decedents, with 64.5% who received at least one PC event. Decedents who received PC were significantly more likely to die in a hospice (39.4% vs 14.5%, P<0.005) and less likely to die in hospital (23.3% vs 40.1%, P<0.05), and were more likely to receive an opioid (53% vs 25.2%, P<0.001). PC initiated more than 2 weeks before death was associated with avoiding a hospital death (≥2 weeks, P<0.001), more than 4 weeks before death was associated with avoiding emergency hospital admissions and increased access to an opioid (≥4 weeks, P<0.001), and more than 33 weeks before death was associated with avoiding late chemotherapy (≥33 weeks, no chemotherapy P=0.019, chemotherapy over 4 weeks P=0.007). CONCLUSION: For decedents with advanced cancer, access to PC and longer duration of PC were significantly associated with better end-of-life quality indicators.

Opioids combined with antidepressants or antiepileptic drugs for cancer pain: Systematic review and meta-analysis.

BACKGROUND: Combining antidepressant or antiepileptic drugs with opioids has resulted in increased pain relief when used for neuropathic pain in non-cancer conditions. However, evidence to support their effectiveness in cancer pain is lacking. AIM: To determine if there is additional benefit when opioids are combined with antidepressant or antiepileptic drugs for cancer pain. DESIGN: Systematic review and meta-analysis. Randomised control trials comparing opioid analgesia in combination with antidepressant or antiepileptic drugs versus opioid monotherapy were sought. Data on pain and adverse events were extracted. Data were pooled using DerSimonian-Laird random-effects meta-analyses, and heterogeneity was assessed. RESULTS: Seven randomised controlled trials that randomised 605 patients were included in the review. Patients' pain was described as neuropathic cancer pain, cancer bone pain and non-specific cancer pain. Four randomised controlled trials were included in the meta-analysis in which opioid in combination with either gabapentin or pregabalin was compared with opioid monotherapy. The pooled standardised mean difference was 0.16 (95% confidence interval, -0.19, 0.51) showing no significant difference in pain relief between the groups. Adverse events were more frequent in the combination arms. Data on amitriptyline, fluvoxamine and phenytoin were inconclusive. CONCLUSION: Combining opioid analgesia with gabapentinoids did not significantly improve pain relief in patients with tumour-related cancer pain compared with opioid monotherapy. Due to the heterogeneity of patient samples, benefit in patients with definite neuropathic cancer pain cannot be excluded. Clinicians should balance the small likelihood of benefit in patients with tumour-related cancer pain against the increased risk of adverse effects of combination therapy.

Patients' responses to the communication of vascular risk in primary care: a qualitative study.

AIM: To examine the perspectives of patients identified as being at 'high risk' of cardiovascular events, with particular reference to the potential responses to risk messages. BACKGROUND: Systematic population screening for cardiovascular disease (CVD) aims to identify those at high risk and provide medication and lifestyle support. In the United Kingdom, this takes the form of the National Health Service Health Check. METHODS: We conducted a qualitative interview study. In 2011 we interviewed 37 patients, from seven UK primary care practices, who were at high risk of developing CVD. FINDINGS: Risk messages were delivered via face-to-face consultations or by letter and were relayed in either a 'downplaying' or 'serious warning' style. Patients' accounts of receiving information about risk revealed two broad response styles: 'committed' (active resistance; commitment to change) and 'non-committed' (procrastination; downplaying and fatalism). Responses to risk messages are usually assumed to be due to individual characteristics but they may be explained by an interaction between the way risk is communicated and the patient's response style.

Understanding causal associations between self-rated health and personal relationships in older adults: A review of evidence from longitudinal studies.

BACKGROUND: As we age we experience many life changes in our health, personal relationships, work, or home life which can impact on other aspects of our life. There is compelling evidence that how we feel about our health influences, or is influenced by, the personal relationships we experience with friends and relatives. Currently the direction this association takes is unclear. AIM: To assess the level of published evidence available on causal links between self-rated health and personal relationships in older adults. METHODS: MEDLINE, CINAHL, and PsycINFO searches from inception to June 2012 and hand searches of publication lists, reference lists and citations were used to identify primary studies utilizing longitudinal data to investigate self-rated health and personal relationships in older adults. RESULTS: Thirty-one articles were identified. Only three articles employed methods suitable to explore causal associations between changes in self-rated health and changes in personal relationships. Two of these articles suggested that widowhood leads to a reduction in self-rated health in the short term, while the remaining article suggested a causal relationship between self-rated health and negative emotional support from family or friends, but this was complex and mediated by self-esteem and sense of control. CONCLUSION: While there is an abundance of longitudinal aging cohorts available which can be used to investigate self-rated health and personal relationships over time the potential for these databases to be used to investigate causal associations is currently not being recognized.

Use of oral direct factor Xa inhibiting anticoagulants in elective hip and knee arthroplasty: a meta-analysis of efficacy and safety profiles compared with those of low-molecular-weight heparins.

Assessing the efficacy and safety profiles of new oral direct Factor Xa (FXa) inhibiting anticoagulants compared with low-molecular-weight heparins (LMWHs) in elective total hip and knee arthroplasty (THA and TKA). The literature review only searched for randomised-controlled trials (RCTs) published before September 2011. Five eligible THA RCTs with a total of 12,184 patients and 5 eligible TKA RCTs with a total of 13,169 patients were identified. Mantel- Haenszel random-effects model was used to create meta-analyses of pooled data for each surgical group. The primary efficacy outcome was the risk of venous thromboembolism (VTE) and all-cause mortality, and the primary safety outcome was the risk of major bleeding. The THA and TKA primary efficacy outcome meta-analyses calculated relative risks (RR) of 0.55 (95% confidence interval 0.32 to 0.94) and 0.68 (95% confidence interval 0.53 to 0.87), respectively in favor of the oral direct FXa inhibitors. The primary safety outcome meta-analyses for the THA and TKA surgical groups revealed an RR of 1.27 (95% confidence interval 0.56 to 2.86) and 0.94 (95% confidence interval 0.44 to 1.98), which shows no significant difference between oral FXa inhibitors and LMWHs. This review demonstrated that oral direct FXa inhibitors have a superior efficacy to LMWHs when used as thromboprophylaxis in both THA and TKA. The safety profile of these new oral anticoagulants was not significantly different to that of LMWHs.

A systematic review of patient reported factors associated with uptake and completion of cardiovascular lifestyle behaviour change.

BACKGROUND: Healthy lifestyles are an important facet of cardiovascular risk management. Unfortunately many individuals fail to engage with lifestyle change programmes. There are many factors that patients report as influencing their decisions about initiating lifestyle change. This is challenging for health care professionals who may lack the skills and time to address a broad range of barriers to lifestyle behaviour. Guidance on which factors to focus on during lifestyle consultations may assist healthcare professionals to hone their skills and knowledge leading to more productive patient interactions with ultimately better uptake of lifestyle behaviour change support. The aim of our study was to clarify which influences reported by patients predict uptake and completion of formal lifestyle change programmes. METHODS: A systematic narrative review of quantitative observational studies reporting factors (influences) associated with uptake and completion of lifestyle behaviour change programmes. Quantitative observational studies involving patients at high risk of cardiovascular events were identified through electronic searching and screened against pre-defined selection criteria. Factors were extracted and organised into an existing qualitative framework. RESULTS: 374 factors were extracted from 32 studies. Factors most consistently associated with uptake of lifestyle change related to support from family and friends, transport and other costs, and beliefs about the causes of illness and lifestyle change. Depression and anxiety also appear to influence uptake as well as completion. Many factors show inconsistent patterns with respect to uptake and completion of lifestyle change programmes. CONCLUSION: There are a small number of factors that consistently appear to influence uptake and completion of cardiovascular lifestyle behaviour change. These factors could be considered during patient consultations to promote a tailored approach to decision making about the most suitable type and level lifestyle behaviour change support.

Individual influences on lifestyle change to reduce vascular risk: a qualitative literature review.

BACKGROUND: Management of cardiovascular risk includes adoption of healthy lifestyles. Uptake and completion rates for lifestyle programmes are low and many barriers and facilitators to lifestyle behaviour change have been reported in the literature. Clarity on which barriers and facilitators to target during consultations in primary care may support a more systematic approach to lifestyle behaviour change in those at high risk of cardiovascular events. AIM: To identify the main barriers and facilitators to lifestyle behaviour change in individuals at high risk of cardiovascular events. DESIGN: A content synthesis of the qualitative literature reporting patient-level influences on lifestyle change. METHOD: Qualitative studies involving patients at high risk of cardiovascular events were identified through electronic searching and screening against predefined selection criteria. Factors (reported influences) were extracted and, using a clustering technique, organised into categories that were then linked to key themes through relationship mapping. RESULTS: A total of 348 factors were extracted from 33 studies. Factors were organised into 20 categories and from these categories five key themes were identified: emotions, beliefs, information and communication, friends and family support, and cost/transport. CONCLUSION: It is possible to organise the large number of self-reported individual influences on lifestyle behaviours into a small number of themes. Further research is needed to clarify which of these patient-level barriers and facilitators are the best predictors of uptake and participation in programmes aimed at helping people to change lifestyle.

A graph-theory method for pattern identification in geographical epidemiology--a preliminary application to deprivation and mortality.

BACKGROUND: Graph theoretical methods are extensively used in the field of computational chemistry to search datasets of compounds to see if they contain particular molecular sub-structures or patterns. We describe a preliminary application of a graph theoretical method, developed in computational chemistry, to geographical epidemiology in relation to testing a prior hypothesis. We tested the methodology on the hypothesis that if a socioeconomically deprived neighbourhood is situated in a wider deprived area, then that neighbourhood would experience greater adverse effects on mortality compared with a similarly deprived neighbourhood which is situated in a wider area with generally less deprivation. METHODS: We used the Trent Region Health Authority area for this study, which contained 10,665 census enumeration districts (CED). Graphs are mathematical representations of objects and their relationships and within the context of this study, nodes represented CEDs and edges were determined by whether or not CEDs were neighbours (shared a common boundary). The overall area in this study was represented by one large graph comprising all CEDs in the region, along with their adjacency information. We used mortality data from 1988-1998, CED level population estimates and the Townsend Material Deprivation Index as an indicator of neighbourhood level deprivation. We defined deprived CEDs as those in the top 20% most deprived in the Region. We then set out to classify these deprived CEDs into seven groups defined by increasing deprivation levels in the neighbouring CEDs. 506 (24.2%) of the deprived CEDs had five adjacent CEDs and we limited pattern development and searching to these CEDs. We developed seven query patterns and used the RASCAL (Rapid Similarity Calculator) program to carry out the search for each of the query patterns. This program used a maximum common subgraph isomorphism method which was modified to handle geographical data. RESULTS: Of the 506 deprived CEDs, 10 were not identified as belonging to any of the seven groups because they were adjacent to a CED with a missing deprivation category quintile, and none fell within query Group 1 (a deprived CED for which all five adjacent CEDs were affluent). Only four CEDs fell within Group 2, which was defined as having four affluent adjacent CEDs and one non-affluent adjacent CED. The numbers of CEDs in Groups 3-7 were 17, 214, 95, 81 and 85 respectively. Age and sex adjusted mortality rate ratios showed a non-significant trend towards increasing mortality risk across Groups (Chi-square = 3.26, df = 1, p = 0.07). CONCLUSION: Graph theoretical methods developed in computational chemistry may be a useful addition to the current GIS based methods available for geographical epidemiology but further developmental work is required. An important requirement will be the development of methods for specifying multiple complex search patterns. Further work is also required to examine the utility of using distance, as opposed to adjacency, to describe edges in graphs, and to examine methods for pattern specification when the nodes have multiple attributes attached to them.

Use of graph theory to identify patterns of deprivation and high morbidity and mortality in public health data sets.

OBJECTIVE: An important part of public health is identifying patterns of poor health and deprivation. Specific patterns of poor health may be associated with features of the geographic environment where contamination or pollution may be occurring. For example, there may be clusters of poor health surrounding nuclear power stations, whereas major roads or rivers may be associated with areas of poor health alongside the feature in chains. Current methods are limited in their capacity to search for complex patterns in geographic data sets. The objective of this study was to determine whether graph theory could be used to identify patterns of geographic areas that have high levels of deprivation, morbidity, and mortality in a public health database. The geographic areas used in the study were enumeration districts (EDs), which are the lowest level of census geography in England and Wales, representing on average 200 households in the 1991 census. More specifically, the study aimed to identify chains of EDs with high deprivation, morbidity, and mortality that might be adjacent to specific types of geographic features, i.e., rivers or major roads. DESIGN: The maximum common subgraph (MCS) algorithm was used to search for seven query patterns of deprivation and poor health within the Trent region. Query pattern 1 represented a linear chain of five EDs and query patterns 2 to 7 represented the possible clusters of the five EDs. To identify chains of EDs with high deprivation, morbidity, and mortality, the results from the query patterns 2 to 7 were used to remove patterns (option 1) and EDs (option 2) from the results of query pattern 1. MEASUREMENTS: Data on the Townsend Material Deprivation Index, standardized long-term limiting illness and standardized all-cause mortality rates were used for the 10,665 EDs within the Trent region. RESULTS: The MCS algorithm retrieved a range of patterns and EDs from the database for the queries. Query pattern 1 identified 3,838 patterns containing a total of 195 EDs. When the patterns retrieved using query patterns 2 to 7 were removed from the 3,838 patterns using option 1, 1,704 patterns remained containing 161 EDs. When the EDs retrieved using query patterns 2 to 7 were removed from the 195 EDs identified by query pattern 1 using option 2, 12 EDs remained. The MCS algorithm was therefore able to reduce the numbers of patterns and EDs to allow manual examination for chains of EDs and for that which might be associated with them. CONCLUSION: The study demonstrates the potential of the MCS algorithm for searching for specific patterns of need. This method has potential for identifying such patterns in relation to local geographic features for public health.
