The effectiveness and cost-effectiveness of a participative community singing programme as a health promotion initiative for older people: protocol for a randomised controlled trial

Background  

The growth in numbers of older people represents a considerable cost to health and social care services in the United Kingdom. There is an acknowledged need to address issues of social exclusion and both the physical and mental health of this age group. In recent years there has been much interest in the potential contribution of the arts to the health of communities and individuals. There is some evidence that participative singing may be of benefit to older people, however studies to date are limited in number and have lacked rigour. There is therefore a need to build on this knowledge base to provide more quantifiable evidence of both effectiveness and cost effectiveness of singing as a health intervention for this population group.     

Effects on leisure activities and social participation of a case management intervention for frail older people living at home: a randomised controlled trial

Frailty causes disability and restrictions on older people's ability to engage in leisure activities and for social participation. The objective of this study was to evaluate the effects of a 1‐year case management intervention for frail older people living at home in Sweden in terms of social participation and leisure activities. The study was a randomised controlled trial with repeated follow‐ups. The sample (n = 153) was consecutively and randomly assigned to intervention (n = 80) or control groups (n = 73). The intervention group received monthly home visits over the course of a year by nurses and physiotherapists working as case managers, using a multifactorial preventive approach. Data collections on social participation, leisure activities and rating of important leisure activities were performed at baseline, 3, 6, 9 and 12 months, with recruitment between October 2006 and April 2011. The results did not show any differences in favour of the intervention on social participation. However, the intervention group performed leisure activities in general, and important physical leisure activities, to a greater extent than the control group at the 3‐month follow‐up (median 13 vs. 11, P = 0.034 and median 3 vs. 3, P = 0.031 respectively). A statistically significantly greater proportion of participants from the intervention group had an increased or unchanged number of important social leisure activities that they performed for the periods from baseline to 3 months (93.2% vs. 75.4%, OR = 4.48, 95% CI: 1.37–14.58). Even though statistically significant findings in favour of the intervention were found, more research on activity‐focused case management interventions is needed to achieve clear effects on social participation and leisure activities.     

Evaluating a community-based walking intervention for hypertensive older people in Taiwan: a randomized controlled trial

OBJECTIVE: To study the effect of a community-based walking intervention on blood pressure among older people. METHOD: The study design was a randomized controlled trial conducted in a rural area of Taiwan between October 2002 and June 2003. A total of 202 participants aged 60 years and over with mild to moderate hypertension was recruited. Participants randomized to the intervention group (n=102) received a six-month community-based walking intervention based on self-efficacy theory. A public health nurse provided both face-to-face and telephone support designed to assist participants to increase their walking. Control group participants (n=100) received usual primary health care. Primary outcome was change in systolic blood pressure and secondary outcomes were exercise self-efficacy, self-reported walking and diastolic blood pressure. RESULTS: At six-month follow-up the mean change in systolic blood pressure was a decrease of 15.4 mmHg and 8.4 mmHg in the intervention and control group, respectively. The difference in mean change between the two groups was -7.0 mmHg (95% CI, -11.5 to -2.5 mmHg, p=0.002). Improvement in exercise self-efficacy scores was greater among intervention group participants (mean difference 1.23, 95% CI, 0.5 to 2.0, p=0.001). Intervention group participants were more likely to report walking more (p<0.0005) but no differences were observed in diastolic blood pressure (p=0.19). CONCLUSIONS: Among hypertensive older people, a six-month community-based walking intervention was effective in increasing their exercise self-efficacy and reducing systolic blood pressure.     

The reduction of disability in community-dwelling frail older people: design of a two-arm cluster randomized controlled trial

Background  

Frailty among older people is related to an increased risk of adverse health outcomes such as acute and chronic diseases, disability and mortality. Although many intervention studies for frail older people have been reported, only a few have shown positive effects regarding disability prevention. This article presents the design of a two-arm cluster randomized controlled trial on the effectiveness, cost-effectiveness and feasibility of a primary care intervention that combines the most promising elements of disability prevention in community-dwelling frail older people.     

Can occupational therapy intervention play a part in maintaining independence and quality of life in older people? A randomised controlled trial

Abstract: The main objective of this study was to see if older people could maintain their quality of life and independence after their homes had been modified and they were using community services as recommended by an occupational therapist. There were 167 study participants aged 69 to 94 years from the Northern Sydney Area. After being assessed at home by an occupational therapist, 105 were randomly allocated to one of two groups, to either have or not have the occupational therapist's recommendations carried out. They were assessed again after six months. A third group did not require any intervention. This group was followed up by telephone and postal questionnaire at six months. The main outcome measures used were the Sickness Impact Profile, the Philadelphia Geriatric Center Morale Scale, the Life Satisfaction Index, assessment of Activities of Daily Living, the Health Assessment Questionnaire and change in residence. After six months there were no difference in outcomes among the three groups. Most study participants remained at a satisfactory level on each measure. Three people had died. One had moved to hostel care and one had moved to a nursing home. A further 14 from the group having no intervention had withdrawn from the study. A secondary objective of this study was to indicate the responsiveness of these outcome measures to change in the short term (over six months) in an elderly population. Twelve-month assessments are in progress and may indicate what to expect from these outcome measures in the medium term.     

Study protocol: a randomised controlled trial investigating the effect of a healthy lifestyle intervention for people with severe mental disorders

Background  

The largest single cause of death among people with severe mental disorders is cardiovascular disease (CVD). The majority of people with schizophrenia and bipolar disorder smoke and many are also overweight, considerably increasing their risk of CVD. Treatment for smoking and other health risk behaviours is often not prioritized among people with severe mental disorders. This protocol describes a study in which we will assess the effectiveness of a healthy lifestyle intervention on smoking and CVD risk and associated health behaviours among people with severe mental disorders.     

Cost-effectiveness of a multidisciplinary fall prevention program in community-dwelling elderly people: a randomized controlled trial (ISRCTN 64716113)

OBJECTIVES: Multidisciplinary and multifactorial interventions seem to be effective in preventing falls. We aimed to assess the cost-effectiveness of a multidisciplinary fall prevention program compared with usual Dutch healthcare in community-dwelling people 65 years of age or older who experienced a fall. METHODS: Cost-effectiveness and cost-utility analysis were performed from a societal perspective. Falls and healthcare utilization were continuously measured for 12 months. Daily functioning and quality of life were measured at baseline, after 4 and 12 months. Bootstrap analyses were performed to estimate uncertainty of the findings and sensitivity analysis to assess the generalizability of assumptions made. RESULTS: One hundred sixty-six participants were randomly allocated to the experimental group and 167 to the control group. The overall response rate was 74 percent. Healthcare and patient and family costs of both groups were comparable. Our analyses showed no effect of the intervention program on falls, daily functioning, or quality of life measures. CONCLUSIONS: The multidisciplinary intervention program to prevent falls was not cost-effective compared with usual care in the Netherlands. Notwithstanding our findings, however, falls still have an important impact on society and individuals in terms of costs and effects. Economic evaluations studying promising interventions to prevent falls, therefore, remain necessary.     

Health promotion for older people in the Czech Republic in a European perspective

This article describes health promotion for older people in the Czech Republic from the European perspective. It is based on findings from the European project healthPROelderly. Implementation of health promotion in the Czech republic as a new public health concept is outlined from the historical point of view. Structures and processes of health promotion in the Czech Republic are described in the context of social policy, demography and health. The European project healthPROelderly is presented and the outcomes of an international literature search statistically analysed. Participating countries were divided into three macro-regions according to their geographical location and political and historical tradition - Mediterranean, West-European and formerly East-European macro-regions. The outcome of correspondence analysis partially confirms the hypothesis on the cultural background of the health promotion activities and strategies. Concerning themes addressed by health promotion projects most countries belonging to the Mediterranean or "Western European" macro-regions have concentrated on similar themes whereas this is not valid for the countries of the "Former Eastern European" macro-region. The hypothesis on macro-regional similarities in relation to settings of health promotion projects was not confirmed. In the conclusions the location of the Czech Republic in an international perspective is discussed and three Czech selected best practice projects are evaluated in relation to the statistical findings.     

Effects of a dietetic treatment in older, undernourished, community-dwelling individuals in primary care: a randomized controlled trial

Purpose

Undernutrition is a prevalent problem in older, community-dwelling individuals. Aim of this study was to determine the effects of a dietetic treatment in older, undernourished, community-dwelling individuals.

Methods

A parallel randomized controlled trial was performed in 146 non-institutionalized, undernourished individuals aged ≥65 years in primary care. Participants were randomly assigned to the intervention (referral to and treatment by a trained dietitian) or control group (no referral). Body weight, physical performance, handgrip strength, energy intake, protein intake and fat-free mass were assessed at baseline, after 3 months and after 6 months.

Results

All randomized participants (n = 146) were included in the intention-to-treat generalized estimating equations analysis (72 in intervention and 74 in control group). No treatment effect was found on the primary outcomes body weight (β = 0.49 kg, 95 % CI: ?0.15–1.12), physical performance (β = 0.15 points, 95 % CI: ?0.33–0.64) and handgrip strength (β = 0.49 kg, 95 % CI: ?0.62–1.60). Furthermore, no treatment effect was found for the secondary outcomes. Predefined subgroup analyses showed a treatment effect on body weight in physically active participants (β = 1.25 kg, 95 % CI: 0.70–2.11) and not in inactive participants (β = ?0.20 kg, 95 % CI: ?1.16–0.75).

Conclusions

After 6 months, a dietetic treatment by trained dietitians does not lead to increases in body weight and physical functioning in older, undernourished, community-dwelling individuals.     

Health effects of green tea catechins in overweight and obese men: a randomised controlled cross-over trial

Regular consumption of green tea may be cardioprotective. In the present study we investigated the health effects of dietary supplementation with green tea catechins and the potential modifying effect of the catechol-O-methyltransferase (COMT) Val/Met genotype. Subjects (sedentary males, aged 40-69 years, with BMI ≥ 28 and ≤ 38 kg/m(2)) were randomly assigned to consume decaffeinated green tea extract (DGT; 530 mg containing about 400 mg total catechins/capsule, twice daily) and placebo in a complete cross-over design. Ambulatory blood pressure and biomarkers of metabolic function (cholesterol, TAG, glucose and insulin) were measured at weeks 0 and 6. Although a marked increase in the concentration of plasma epigallocatechin gallate (EGCG), urinary epigallocatechin (EGC) and urinary 4'-O-methyl EGC was found after DGT treatment, no effect on blood pressure or biomarkers of metabolic function was observed. However, a period × treatment interaction (P < 0·05) was detected for body-weight change. Despite a similar increase in estimated energy intake during intervention period 1, body weight decreased by 0·64 (sd 2·2) kg and increased by 0·53 (sd 1·9) kg in the DGT and placebo groups, respectively (P = 0·025), suggesting a protective effect of green tea catechins on weight gain. Additionally, the COMT Val/Met genotype influenced urinary accumulation of EGC and 4'-O-methyl EGC (P < 0·01). Mean concentrations were lower in individuals homozygous for the high-activity G-allele, possibly reflecting increased metabolic flux and a more rapid conversion to downstream metabolic species, compared with individuals carrying at least one copy of the low-activity A-allele. Additional studies are needed to confirm these findings and further explore the modifying effect of genotype.     

Randomized intervention trial on preventive home visits to older people: baseline and follow-up characteristics of participants and non-participants

AIMS: In controlled intervention studies, a selective non-response or refusal to participate at baseline may bias measurable effects of the intervention. The aim of this study was to compare mortality and nursing home admission among older persons who accepted (participants) and older person who declined (non-participants) to join a controlled feasibility trial, and to describe and evaluate defined subgroups of non-participants. METHODS: Prospective controlled three-year intervention study (1999-2001) in 34 Danish municipalities with five-year follow-up. Randomization and intervention (education of municipality employees) was done at municipality level. In total 5,788 home-dwelling 75- and 80-year-olds living in these municipalities were invited to participate in the study. Written consent was obtained from 4,060 persons (participation rate 71%). RESULTS: During five-year follow-up non-participants had a higher mortality rate (survival analysis risk ratio RR = 1.5, 95% CI = 1.3-1.7, p<0.0001) and a higher rate of nursing home admissions (RR = 1.7, 95% CI = 1.3-2.1, p<0.0001) compared with participants. Subgroups of non-participants describing themselves as "too ill" and persons "not reached" had a significantly higher mortality rate and risk of admission to nursing home than participants, whereas the subgroups of non-participants describing themselves as "too healthy" and having "another reason for refusal" did not differ from the participants. There was no difference in mortality rates between non-participants living in intervention municipalities compared with non-participants living in control municipalities. CONCLUSIONS: Mortality and nursing home admissions were higher among non-participants. Selection participation bias was of no clinical importance since subgroups of non-participants eligible for the intervention did not differ from the participants.     

Active health promotion in old age: methodology of a preventive intervention programme provided by an interdisciplinary health advisory team for independent older people

People live longer today and, therefore, have more opportunity to a quire non-fatal disabilities in old age. Disability in old age has multifactorial causes, including physiological, psychological and social risk factors. An innovative health promotion and prevention programme designed for elderly people was developed at the Albertinen-Haus Geriatrics Centre in Hamburg in 2001 and offered to residents of the city aged 60 years and over who were living in their own homes. Eligible individuals were independent, i.e. without disabilities (not in need of care or support according to the German health systems categorization), and without cognitive impairment. The programme focuses on areas of health behaviour that are interrelated and target self-efficacy and empowerment. The programme used an interdisciplinary approach in group sessions. The team of health promotion advisers (Gesundheitsberater-Team) consisted of members of four professions, i.e. physician, social worker, physiotherapist, and nutrition and home economics specialist. We decided to work in group sessions because of the potential for positive dynamic effects between group participants and for reasons of cost. We also developed a curriculum to train professional members of interdisciplinary geriatric teams to work as health promotion advisers for elderly people.
