ABSTRACT: OBJECTIVE: To examine the effect of dementia on longer term survival after hospital admission, and to assess whether dementia is an independent predictor of mortality. This information is vital for the provision of appropriate care. METHODS: A prospective cohort study, in a large urban acute general hospital, of 616 people (70 years and older) with unplanned medical admission. The principal exposure was DSM-IV dementia and main outcome mortality risk. Dementia severity was analysed by using the Functional Assessment Staging scale. We examined a range of modifying variables: acute physiological disturbance (Acute Physiology and Chronic Health Evaluation), chronic comorbidity (Charlson Comorbidity Index, CCI) and pressure sore risk (Waterlow score). RESULTS: A total 42.4% of the cohort had dementia. Nearly half (48.3%) had died 12 months after admission (median survival time 1.1 years compared with 2.7 years in people without dementia). Unadjusted hazard ratios for mortality in people with dementia was 1.66 (95% CI 1.35-2.04) and for people with moderately severe/severe dementia 2.01 (95% CI 1.57-2.57). After sequential adjustment (age, gender, Acute Physiology and Chronic Health Evaluation score, Charlson Comorbidity Index and Waterlow score), patients with dementia had a mortality risk of 1.24 (95% CI 0.95-1.60) and those with moderately severe/severe dementia 1.33 (0.97-1.84). CONCLUSIONS: People with dementia had half the survival time of those without dementia. The effect of dementia on mortality was reduced after adjustment, particularly by the Waterlow score, a marker of frailty. The median survival of 1 year suggests clinicians should consider adopting a supportive approach to the care of older people with moderate/severe dementia who have an emergency hospital admission.

ABSTRACT: CONTEXT: Two million people across the U.K. are living with cancer, often experienced as a long-term condition. They may have unmet needs after active treatment. Rehabilitation aims to address these needs, maximize psychological and physical function, and enable minimum dependency regardless of life expectancy. OBJECTIVES: We aimed to test, in a randomized controlled trial, the clinical and cost-effectiveness of a rehabilitation intervention for patients with advanced, recurrent cancer. METHODS: We conducted a two-arm, wait-list control, randomized trial of a complex rehabilitation intervention delivered by a hospice-based multidisciplinary team vs. usual care for active, progressive, recurrent hematological and breast malignancies, with a follow-up at three months. The primary outcome was the psychological subscale of the Supportive Care Needs Survey (SCNS). Secondary outcomes were other domains on SCNS, psychological status, continuity of care, quality of life, and resource use. RESULTS: Forty-one participants were enrolled and 36 completed the trial. The primary outcome was significantly lower in the intervention arm (adjusted difference -16.8, 95% CI -28.34 to -5.3; P = 0.006). The SCNS physical and patient care subscales (-14.2, 95% CI -26.2 to -2.2; P = 0.02 and -7.4, 95% CI -13.7 to -1.1; P = 0.02, respectively) and self-reported health state (12.8, 95% CI 3.2 to 22.4; P = 0.01) also differed significantly. The incremental cost-effectiveness ratio was £19,390 per quality-adjusted life year. CONCLUSION: This intervention significantly reduced the unmet needs of cancer survivors and it is likely that it is cost-effective. Despite small numbers, the main effect size was robust. We recommend implementation alongside evaluation in wider clinical settings and patient populations.

ABSTRACT: BACKGROUND: Delirium is a syndrome characterised by a disturbance of consciousness (often fluctuating), cognition and perception. In terminally ill patients it is one of the most common causes of admission to clinical care. Delirium may arise from any number of causes and treatment should be directed at addressing these causes rather than the symptom cluster. In cases where this is not possible, or treatment does not prove successful, the use of drug therapy to manage the symptoms may become necessary. This is an update of the review published on 'Drug therapy for delirium in terminally ill adult patients' in The Cochrane Library 2004, Issue 2 ( Jackson 2004). OBJECTIVES: To evaluate the effectiveness of drug therapies to treat delirium in adult patients in the terminal phase of a disease. SEARCH METHODS: We searched the following sources: CENTRAL (The Cochrane Library 2012, Issue 7), MEDLINE (1966 to 2012), EMBASE (1980 to 2012), CINAHL (1982 to 2012) and PSYCINFO (1990 to 2012). SELECTION CRITERIA: Prospective trials with or without randomisation or blinding involving the use of drug therapies for the treatment of delirium in adult patients in the terminal phase of a disease. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trial quality using standardised methods and extracted trial data. We collected outcomes related to efficacy and adverse effects. MAIN RESULTS: One trial met the criteria for inclusion. In the 2012 update search we retrieved 3066 citations but identified no new trials. The included trial evaluated 30 hospitalised AIDS patients receiving one of three agents: chlorpromazine, haloperidol and lorazepam. The trial under-reported key methodological features. It found overall that patients in the chlorpromazine group and those in the haloperidol group had fewer symptoms of delirium at follow-up (to below the diagnostic threshold using the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) and that both were equally effective (at two days mean difference (MD) 0.37; 95% confidence interval (CI) -4.58 to 5.32; between two and six days MD -0.21; 95% CI -5.35 to 4.93). Chlorpromazine and haloperidol were found to be no different in improving cognitive status in the short term (at 48 hours) but at subsequent follow-up cognitive status was reduced in those taking chlorpromazine. Improvements from baseline to day two for patients randomised to lorazepam were not apparent. All patients on lorazepam (n = 6) developed adverse effects, including oversedation and increased confusion, leading to trial drug discontinuation. AUTHORS' CONCLUSIONS: There remains insufficient evidence to draw conclusions about the role of drug therapy in the treatment of delirium in terminally ill patients. Thus, practitioners should continue to follow current clinical guidelines. Further research is essential.

ABSTRACT: Palliative care rehabilitation aims to maximize physical and psychological functioning, but negative thoughts can hinder patients from attempting this approach. Acceptance and commitment therapy (ACT), a modified form of cognitive behavioral therapy, encourages individuals to experience and manage negative emotions by focusing on changing individual behavior and so improve functioning. ACT has been used in many health-related behavioral interventions but not in palliative care rehabilitation.
To investigate the relationship between acceptance (often called experiential acceptance in ACT) and psychological and physical status.
Cross-sectional study in which a consecutive sample of patients attending a specialist palliative care day therapy unit for rehabilitation completed the Acceptance and Action Questionnaire-II to measure acceptance and the Kessler-10 questionnaire to measure psychological morbidity. Physical function was assessed by a timed two-minute walking test and one-minute sit-to-stand test. Correlation statistics and multivariable regression analyses were used to explore the strength of relationships between acceptance and psychological morbidity and physical function.
One hundred one patients were recruited, mainly white women with a mean age of 64 years. Correlation analysis showed a negative association between acceptance and psychological morbidity (r=-0.59) and a positive association between acceptance and sit to stand (r=0.27) and distance walked (r=0.21). All three of these relationships were statistically significant after adjustment.
These associations suggest that it may be possible to reduce psychological morbidity and improve physical mobility by increasing patients' acceptance using an ACT-based intervention. Future work is now needed to develop an ACT-based intervention in palliative care rehabilitation and test its acceptability and feasibility.

ABSTRACT: Recruiting smokers to smoking cessation trials is challenging and participation rates are often low. Consequently, the interventions evaluated may fail to reach a broad spectrum of the target population, thus compromising the generalizability of the findings. Brief interventions, using proactive recruitment, are likely to attract a broader and more representative proportion of the population.
We explored the factors that influenced recruitment into a trial evaluating computer-tailored feedback reports that aimed to help smokers to quit [the ESCAPE (Effectiveness of computer-tailored Smoking Cessation Advice in Primary Care) study] in order to investigate the possibilities for increasing recruitment into smoking cessation trials.
Current cigarette smokers, identified from GP records, were invited to participate in the study. The main outcome measure was the recruitment rate, i.e. the proportion of participants who responded and were randomized to one of the intervention groups. Predictor variables included geographical region, level of deprivation, practice characteristics and the number and timing of mailings of questionnaires.
The recruitment rate varied by practice (2.5-19.8%) and differed significantly between regions (from 16.3% in Scotland to 8.4% in London, P < 0.001). Recruitment decreased significantly by 1.1% between the lowest and highest quintiles of deprivation (P = 0.012), measured by Index of Multiple Deprivation scores, and decreased by 1.33% for every extra 10% smokers identified within a practice population (P = 0.010). Sending reminders increased recruitment by 7.5% (P < 0.001). Multivariable analysis showed region and length of time between mailings were the main predictors of recruitment.
Proactive recruitment methods can increase participation in smoking cessation trials and weighting the target sample in favour of more deprived areas will recruit a more representative sample. The number and timing of mailings to potential participants can also increase recruitment.

ABSTRACT: Abstract Background Whilst evidence suggests cognitive behaviour therapy (CBT) may be effective for depressed older people in a primary care setting, few studies have examined its cost-effectiveness. The aim of this study was to compare the cost-effectiveness of cognitive behaviour therapy (CBT), a talking control (TC) and treatment as usual (TAU), delivered in a primary care setting, for older people with depression. Methods Cost data generated from a single blind randomised controlled trial of 204 people aged 65 years or more were offered only Treatment as Usual, or TAU plus up to twelve sessions of CBT or a talking control is presented. The Beck Depression Inventory II (BDI-II) was the main outcome measure for depression. Direct treatment costs were compared with reductions in depression scores. Cost-effectiveness analysis was conducted using non-parametric bootstrapping. The primary analysis focussed on the cost-effectiveness of CBT compared with TAU at 10 months follow up. Results Complete cost data were available for 198 patients at 4 and 10 month follow up. There were no significant differences between groups in baseline costs. The majority of health service contacts at follow up were made with general practitioners. Fewer contacts with mental health services were recorded in patients allocated to CBT, though these differences were not significant. Overall total per patient costs (including intervention costs) were significantly higher in the CBT group compared with the TAU group at 10 month follow up (difference £427, 95% CI: £56 - £787, p < 0.001). Reductions in BDI-II scores were significantly greater in the CBT group (difference 3.6 points, 95% CI: 0.7-6.5 points, p = 0.018). CBT is associated with an incremental cost of £120 per additional point reduction in BDI score and a 90% probability of being considered cost-effective if purchasers are willing to pay up to £270 per point reduction in the BDI-II score. Conclusions CBT is significantly more costly than TAU alone or TAU plus TC, but more clinically effective. Based on current estimates, CBT is likely to be recommended as a cost-effective treatment option for this patient group if the value placed on a unit reduction in BDI-II is greater than £115.

ABSTRACT: Patients with advanced dementia often receive poor end-of-life care. We aimed to design and pilot a palliative care and advance care plan (ACP) intervention. Patients had undergone emergency hospital admission and had severe dementia. The intervention consisted of a palliative care patient assessment which informed an ACP discussion with the carer, who was offered the opportunity to write an ACP for the person with dementia. Carer-patient dyads were randomized to 'usual care' or the intervention. Carer-related outcome measures included the Kessler Distress Scale, Decision Satisfaction Inventory, Client Satisfaction Questionnaire and the Euroqol-5D, measured at baseline, six weeks, six months and three months after bereavement. The Satisfaction with End of Life Care in Dementia Scale was completed if the patient died. The 32 patient participants were physically frail and in the advanced stages of dementia: 62% had pressure damage to the skin, all needed feeding assistance and 95% were in pain. Nearly 50% died during the six-month follow-up period. Carers were difficult to recruit during acute admission; 33 patients and carers entered the study (22 intervention arm; 11 control arm). Only seven carers made ACPs. The care planning discussion was well received, but few carers wrote an ACP, despite intensive support from an experienced nurse specialist. Advance care planning is, in theory, a necessary intervention for people with severe dementia; the reluctance of carers to write plans needs to be explored further.

ABSTRACT: Patients in the terminal phase of a disease may have complex needs. It is often family and friends who play a central role in providing support, despite health professional input and regardless of whether the patient is at home or elsewhere. Such informal caring may involve considerable physical, psychological, and economic stresses. A range of supportive programmes for caregivers is being developed including psychological support and practical assistance.
To assess the effects of supportive interventions that aim to improve the psychological and physical health of informal caregivers of patients in the terminal phase of their illness.
We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 2 2010); MEDLINE (1950 to May 2010); EMBASE (1980 to May 2010); PsycINFO (1872 to May 2010); CINAHL (1937 to May 2010); National Health Service Research Register (2000 to November 2008) and Dissertation Abstracts (1716 to May 2010). We searched the reference lists of relevant studies; contacted experts; and handsearched journals.
Randomised controlled trials (RCTs) of interventions to support adults who were caring for a friend or relative with a disease in the terminal phase. Interventions could include practical and emotional support and/or the facilitation of coping skills. Interventions could support caregivers indirectly via patient care.
Two authors independently screened citations against the selection criteria. Data were extracted by one author and checked by another. This included extraction of any adverse effects. Risk of bias assessment was undertaken by two authors. We contacted trial authors to obtain missing information. Trial data were combined, where appropriate, on the review's primary outcomes.
We included eleven RCTs involving 1836 caregiver participants. Nine interventions were delivered directly to the caregiver. Seven of these provided support in the caring role, another involved a family life review, and one grief therapy. None provided practical support. The other two interventions aimed to support caregivers indirectly via patient care. Overall the risk of bias is unclear, as all trials under-reported methods.There is low quality evidence that interventions directly supporting the caregiver significantly reduce psychological distress in the short term (8 trials: standardised mean difference (SMD) -0.15; 95% confidence interval (CI) -0.28 to -0.02). There is also low quality evidence that these interventions in the short term may marginally improve coping skills and quality of life, but neither results were statistically significant (7 trials: SMD -0.05; 95% CI -0.24 to 0.14; 6 trials: SMD 0.08; 95% CI -0.11 to 0.26, respectively). One study assessed physical outcomes, specifically sleep improvement, and found no difference (median effect 0.00). No study measured health service use or adverse outcomes. In one study, however, a subgroup of intervention participants had higher levels of family conflict.Evidence was less clear on the indirect interventions. While both trials in this category found that supporting the patient may reduce psychological distress, none of the four assessments were statistically significant. There were no evaluations of coping with the caring role, quality of life, service use or adverse outcomes. In one trial there was no difference between trial arms in the proportion of caregivers reporting good physical health.
There is evidence that supportive interventions may help reduce caregivers' psychological distress. These findings suggest that practitioners should enquire about the concerns of caregivers and should consider that they may benefit from additional support. There is, however, a need for further research to explore the benefits identified, and to assess the interventions' effects on physical health, and potential harms. Trials need to report their methods fully.

ABSTRACT: In resource-limited settings, most perinatally HIV-1-infected infants do not receive timely antiretroviral therapy because early HIV-1 diagnosis is not available or affordable.
To assess the performance of a low-cost in-house real-time polymerase chain reaction (PCR) assay to detect HIV-1 DNA in infant dried blood spots (DBS).
One thousand three hundred nineteen DBS collected throughout Thailand from non-breast-fed infants born to HIV-1-infected mothers were shipped at room temperature to a central laboratory.In-house real-time DNA PCR results were compared with Roche Amplicor HIV-1 DNA test (Version 1.5) results. In addition, we verified the Roche test performance on DBS sampled from 1218 other infants using as reference HIV serology result at 18 months of age.
Real-time DNA PCR and Roche DNA PCR results were 100% concordant. Compared with HIV serology results, the Roche test sensitivity was 98.6% (95% confidence interval: 92.6% to 100.0%) and its specificity at 4 months of age was 99.7% (95% confidence interval: 99.2% to 99.9%).
In-house real-time PCR performed as well as the Roche test in detecting HIV-1 DNA on DBS in Thailand. Combined use of DBS and real-time PCR assays is a reliable and affordable tool to expand access to early HIV-1 diagnosis in remote and resource-limited settings, enabling timely treatment for HIV-1-infected infants.
