The impact of reminiscence on the quality of life of residents with dementia in long‐stay care

There is increasing recognition of the potential use of reminiscence in maintaining or improving the quality of life of people with dementia. Despite being used widely in dementia care, evidence on the effectiveness of reminiscence remains uncertain.

Effectiveness of a structured education reminiscence-based programme for staff on the quality of life of residents with dementia in long-stay units: A study protocol for a cluster randomised trial

BackgroundCurrent projections indicate that there will be a significant increase in the number of people with dementia in Ireland, from approximately 40,000 at present to 100,000 by 2036. Psychosocial interventions, such as reminiscence, have the potential to improve the quality of life of people with dementia. However, while reminiscence is used widely in dementia care, its impact on the quality of life of people with dementia remains largely undocumented and there is a need for a robust and fair assessment of its overall effectiveness. The DementiA education programme incorporating RE miniscence for S taff study will evaluate the effectiveness of a structured reminiscence-based education programme for care staff on the quality of life of residents with dementia in long-stay units.Methods/DesignThe study is a two-group, single-blind cluster randomised trial conducted in public and private long-stay residential settings in Ireland. Randomisation to control and intervention is at the level of the long-stay residential unit. Sample size calculations suggest that 18 residential units each containing 17 people with dementia are required for randomisation to control and intervention groups to achieve power of at least 80% with alpha levels of 0.05. Each resident in the intervention group is linked with a nurse and care assistant who have taken the structured reminiscence-based education programme. Participants in the control group will receive usual care. The primary outcome is quality of life of residents as measured by the Quality of Life-AD instrument. Secondary outcomes include agitation, depression and carer burden. Blinded outcome assessment is undertaken at baseline and at 18-22 weeks post-randomisation.DiscussionTrials on reminiscence-based interventions for people with dementia have been scarce and the quality of the information arising from those that have been done has been undermined by methodological problems, particularly in relation to scale and scope. This trial is powered to deliver more credible and durable results. The trial may also convey process utility to a long-stay system in Ireland that has not been geared for education and training, especially in relation to dementia. The results of this trial are applicable to long-stay residential units in Ireland and internationally.Trial registrationCurrent Controlled Trials ISRCTN99651465

Primary care organisational interventions for secondary prevention of ischaemic heart disease: a systematic review and meta-analysis

BACKGROUND Ischaemic heart disease (IHD) is the most common cause of death worldwide. AIM To determine the long-term impact of organisational interventions for secondary prevention of IHD. DESIGN AND SETTING Systematic review and meta-analysis of studies from CENTRAL, MEDLINE(®), Embase, and CINAHL published January 2007 to January 2013. METHOD Searches were conducted for randomised controlled trials of patients with established IHD, with long-term follow-up, of cardiac secondary prevention programmes targeting organisational change in primary care or community settings. A random-effects model was used and risk ratios were calculated. RESULTS Five studies were included with 4005 participants. Meta-analysis of four studies with mortality data at 4.7-6 years showed that organisational interventions were associated with approximately 20% reduced mortality, with a risk ratio (RR) for all-cause mortality of 0.79 (95% confidence interval [CI] = 0.66 to 0.93), and a RR for cardiac-related mortality of 0.74 (95% CI = 0.58 to 0.94). Two studies reported mortality data at 10 years. Analysis of these data showed no significant differences between groups. There were insufficient data to conduct a meta-analysis on the effect of interventions on hospital admissions. Additional analyses showed no significant association between organisational interventions and risk factor management or appropriate prescribing at 4.7-6 years. CONCLUSION Cardiac secondary prevention programmes targeting organisational change are associated with a reduced risk of death for at least 4-6 years. There is insufficient evidence to conclude whether this beneficial effect is maintained indefinitely.

Six-year follow-up of the SPHERE RCT: secondary prevention of heart disease in general practice.

Objective To determine the long-term effectiveness of a complex intervention in primary care aimed at improving outcomes for patients with coronary heart disease. Design A 6-year follow-up of a cluster randomised controlled trial, which found after 18 months that both total and cardiovascular hospital admissions were significantly reduced in intervention practices (8% absolute reduction). Setting 48 general practices in the Republic of Ireland and Northern Ireland. Participants 903 patients with established coronary heart disease at baseline in the original trial. Intervention The original intervention consisted of tailored practice and patient plans; training sessions for practitioners in medication prescribing and behavioural change; and regular patient recall system. Control practices provided usual care. Following the intervention period, all supports from the research team to intervention practices ceased. Outcome measures Primary outcome: hospital admissions, all cause and cardiovascular; secondary outcomes: mortality; blood pressure and cholesterol control. Results At 6-year follow-up, data were collected from practice records of 696 patients (77%). For those who had died, we censored their data at the point of death and cause of death was established. There were no significant differences between the intervention and control practices in either total (OR 0.83 (95% CI 0.54 to 1.28)) or cardiovascular hospital admissions (OR 0.91 (95% CI 0.49 to 1.65)). We confirmed mortality status of 886 of the original 903 patients (98%). There were no significant differences in mortality (15% in intervention and 16% in control) or in the proportions of patients above target control for systolic blood pressure or total cholesterol. Conclusions Initial significant differences in the numbers of total and cardiovascular hospital admissions were not maintained at 6 years and no differences were found in mortality or blood pressure and cholesterol control. Policymakers need to continue to assess the effectiveness of previously efficacious programmes. Trial registration number Current Controlled Trials ISRCTN24081411.

Patient reported health status and all-cause mortality in patients with coronary heart disease.

Purpose Patients with coronary heart disease (CHD) experience reduced quality of life which may be associated with mortality in the longer term. This study explores whether patient-rated physical and mental health status was associated with mortality at 6-year follow-up among patients with CHD attending primary care in Ireland and Northern Ireland. Methods This study is a secondary data analysis of patients with CHD recruited to a cluster randomized controlled trial from 2004 to 2010. Data collected included patient-rated physical component summary (PCS) and mental component summary (MCS) scores of health status (from the 12-Item Short-Form Health Survey (SF-12)), demographics and clinical parameters at baseline, and all-cause mortality at 6-year follow-up. Multivariate regression was conducted using generalized estimating equations (GEE) with a log-link function. Results are presented as odds ratios (ORs) and 95% confidence intervals (CIs). Results The study consisted of 762 individuals with mean age 67.6 years [standard deviation (SD): 9.8], and was 29% female. Mean baseline SF-12 mental (MCS) and physical (PCS) component scores were 50.0 (SD: 10.8) and 39.6 (SD: 11.2), respectively. At 6-year follow-up, the adjusted OR for the baseline MCS for mortality was 0.97 (95% CI: 0.95-0.99) and for the PCS 0.97 (95% CI: 0.95-0.99). For every five-point increase in MCS and PCS scores, there was a 14% reduction in the likelihood of all-cause mortality. Conclusions Overall, the magnitude of effect for both mental health status and physical health status was similar; higher scores were significantly associated with a lower risk of mortality at 6-year follow-up.
