Interventions to prevent disability in frail community-dwelling elderly: a systematic review

BackgroundThere is an interest for intervention studies aiming at the prevention of disability in community-dwelling physically frail older persons, though an overview on their content, methodological quality and effectiveness is lacking.MethodsA search for clinical trials involved databases PubMed, CINAHL and Cochrane Central Register of Controlled Trials and manually hand searching. Trials that included community-dwelling frail older persons based on physical frailty indicators and used disability measures for outcome evaluation were included. The selection of papers and data-extraction was performed by two independent reviewers. Out of 4602 titles, 10 papers remained that met the inclusion criteria. Of these, 9 were of sufficient methodological quality and concerned 2 nutritional interventions and 8 physical exercise interventions.ResultsNo evidence was found for the effect of nutritional interventions on disability measures. The physical exercise interventions involved 2 single-component programs focusing on lower extremity strength and 6 multi-component programs addressing a variety of physical parameters. Out of 8 physical exercise interventions, three reported positive outcomes for disability. There was no evidence for the effect of single lower extremity strength training on disability. Differences between the multi-component interventions in e.g. individualization, duration, intensity and setting hamper the interpretation of the elements that consistently produced successful outcomes.ConclusionThere is an indication that relatively long-lasting and high-intensive multicomponent exercise programs have a positive effect on ADL and IADL disability for community-living moderate physically frail older persons. Future research into disability prevention in physical frail older persons could be directed to more individualized and comprehensive programs.

An international study on measuring social support: Interactions and satisfaction

Recently, a new instrument was developed to measure social support. It consists of two parts; the Social Support Questionnaire for Transactions (SSQT) and the Social Support Questionnaire for Satisfaction with the supportive transactions (SSQS). The SSQT measures the number of supportive interactions and has proved to have good psychometric properties. From the taxonomy that was used for the present study, it results that social support in general consists of two aspects. There are, on the one hand, actual supportive transactions and, on the other hand, the perception of being supported or the satisfaction with the social support provided. In the present study, two research questions were addressed. The first concerned the psychometric properties of the SSQS, measuring the individuals satisfaction with the supportive interactions provided. Secondly, the relative contribution of both supportive interactions (the SSQT) and the satisfaction with the support provided (the SSQS) were assessed, in explaining the level of health related quality of life outcome. The data of 744 rheumatoid arthritis (RA) patients from four different countries (116 French, 238 Norwegian, 98 Swedish and 292 Dutch patients) were used in the present study. At the entry of the study, all patients fulfilled four out of seven American Rheumatism Association (ARA) criteria and had a disease duration of 4 years or less. The results of the study indicate that the SSQS has good psychometric properties across countries. Cronbachs alpha for the emotional support scales was 0.80 or more, and for the instrumental support subscales around 0.60. The standardized regression coefficients demonstrated that, compared to supportive interactions, support satisfaction was more relevant in explaining health related quality of life measures, although it is recommended that the SSQT and SSQS be used to complement each other.

The psychometric properties of three self-report screening instruments for identifying frail older people in the community.

BackgroundFrailty is highly prevalent in older people. Its serious adverse consequences, such as disability, are considered to be a public health problem. Therefore, disability prevention in community-dwelling frail older people is considered to be a priority for research and clinical practice in geriatric care. With regard to disability prevention, valid screening instruments are needed to identify frail older people in time. The aim of this study was to evaluate and compare the psychometric properties of three screening instruments: the Groningen Frailty Indicator (GFI), the Tilburg Frailty Indicator (TFI) and the Sherbrooke Postal Questionnaire (SPQ). For validation purposes the Groningen Activity Restriction Scale (GARS) was added.MethodsA questionnaire was sent to 687 community-dwelling older people (≥ 70 years). Agreement between instruments, internal consistency, and construct validity of instruments were evaluated and compared.ResultsThe response rate was 77%. Prevalence estimates of frailty ranged from 40% to 59%. The highest agreement was found between the GFI and the TFI (Cohens kappa = 0.74). Cronbachs alpha for the GFI, the TFI and the SPQ was 0.73, 0.79 and 0.26, respectively. Scores on the three instruments correlated significantly with each other (GFI - TFI, r = 0.87; GFI - SPQ, r = 0.47; TFI - SPQ, r = 0.42) and with the GARS (GFI - GARS, r = 0.57; TFI - GARS, r = 0.61; SPQ - GARS, r = 0.46). The GFI and the TFI scores were, as expected, significantly related to age, sex, education and income.ConclusionsThe GFI and the TFI showed high internal consistency and construct validity in contrast to the SPQ. Based on these findings it is not yet possible to conclude whether the GFI or the TFI should be preferred; data on the predictive values of both instruments are needed. The SPQ seems less appropriate for postal screening of frailty among community-dwelling older people.

Factors affecting quality of life in lower limb amputees

Background: Quality of life (QoL) is increasingly being recognized as an important outcome for rehabilitation programs, and has mainly been used to compare the efficacy of interventions or to compare amputees with other diseased populations. There is relatively a limited number of studies primarily focusing on analyzing the multitude of factors influencing QoL in amputees. Objectives: To identify important background and amputation related factors which affect quality of life (QoL) in lower limb amputees, and to compare QoL profile of amputees’ to that of general population. Study design: Cross-sectional. Methods: Lower limb amputees 18 years and above from a rehabilitation centre, a limb-fitting centre and four limb-fitting camps were interviewed (n = 605). Structured questionnaires included patient background and amputation characteristics, and the MOS short-form health survey (SF-36) for assessing QoL. The SF-36 was administered to a general adult population using purposive sampling (n = 184). Results: SF-36 PCS and MCS scores were found to be significantly lower for amputees when compared to those for the general population. In this study, employment status, use of an assistive device, use of a prosthesis, comorbidities, phantom-limb pain and residual stump pain were found to predict both PCS and MCS scores significantly, and explained 47.8% and 29.7% of variance respectively. Age and time since amputation accounted for an additional 3% of variance in PCS scores. Conclusions: The abovementioned factors should be addressed in order to ensure holistic reintegration and participation, and to enable the amputees to regain or maintain QoL. Prospective longitudinal studies are recommended to systematically study the change in QoL over time and to assess its determinants. Clinical relevance Proper appraisal of abovementioned factors in the rehabilitation programme would assist in establishing a treatment protocol, which would adequately address QoL in amputees.

A multifactorial intervention for the prevention of falls in psychogeriatric nursing home patients, a randomised controlled trial (RCT)

OBJECTIVE to evaluate the effectiveness of a multifactorial intervention on incidence of falls in psychogeriatric nursing home patients. DESIGN cluster-randomised controlled 12-month trial. SETTING psychogeriatric wards in 12 nursing homes in The Netherlands. PARTICIPANTS psychogeriatric nursing home patients (n = 518). INTERVENTION a general medical assessment and an additional specific fall risk evaluation tool, applied by a multidisciplinary fall prevention team, resulting in general and individual fall prevention activities. MEASUREMENTS falls. RESULTS there were 355 falls in 169.5 patient-years (2.09 falls per patient per year) in the intervention group and 422 falls in 166.3 patient-years (2.54 falls per patient per year) in the control group. Intention-to-treat analysis with adjustment for ward-related and patient-related parameters, and intra-cluster correlation, showed that the intervention group had a significantly lower mean fall incidence rate than the control group (rate ratio = 0.64, 95% CI = 0.43-0.96, P = 0.029). Subgroup analyses showed that fall risk declined further as patients participated longer in the intervention programme. CONCLUSION the introduction of a structured multifactorial intervention to prevent falls in psychogeriatric nursing home patients significantly reduces the number of falls. This reduction is substantial and of high clinical relevance.

Social participation through the eyes of people with aphasia

BACKGROUND Little is known about the way people with aphasia perceive their social participation and its influencing factors. AIMS To explore how people with aphasia perceive participation in society and to investigate influencing factors. METHODS & PROCEDURES In this qualitative study thirteen persons with aphasia and twelve central caregivers kept a pre-structured diary over two weeks, followed by a semi-structured interview. Diaries and interviews were transcribed verbatim and analysed by two researchers independently using codes, categories and central themes inductively. Plausibility of the analyses was discussed several times with a third independent senior-researcher. In a focus group interview, the results were discussed with the participants. OUTCOMES & RESULTS The number of social activities and the character of these activities are not as important as the perceived engagement in the social activities for the participants. People with aphasia feel isolated but want to feel engaged. They feel burdensome to others and wish to function in an ordinary way. Extracting information from conversations is difficult but they want to know what is going on. Often they are not able to work and they wish to contribute to the community in other ways. Although they often feel stigmatized, they wish to be respected. Often they do not reach that goal. Perceived factors influencing engagement in social participation can be divided into personal, social and environmental factors. The following personal factors are reported: motivation, physical and psychological condition and communication skills. The social factors are: the role of the central caregiver and the characteristics of the communication partner(s), namely willingness, skills and knowledge. The environmental factors refer to quietness and familiarity of the place in which the person with aphasia live. CONCLUSIONS Social participation is a theoretical concept that people with aphasia do not use. Instead, people speak in terms of engagement, involvement, having a feeling of belonging. People with aphasia describe the degree of engagement in activities in social life domains (i.e. the quality of activities) as more important than the quantity of performing activities.

The predictive validity of three self-report screening instruments for identifying frail older people in the community

BackgroundIf brief and easy to use self report screening tools are available to identify frail elderly, this may avoid costs and unnecessary assessment of healthy people. This study investigates the predictive validity of three self-report instruments for identifying community-dwelling frail elderly.MethodsThis is a prospective study with 1-year follow-up among community-dwelling elderly aged 70 or older (n = 430) to test sensitivity, specificity, and positive and negative predicted values of the Groningen Frailty Indicator, Tilburg Frailty Indicator and Sherbrooke Postal Questionnaire on development of disabilities, hospital admission and mortality. Odds ratios were calculated to compare frail versus non-frail groups for their risk for the adverse outcomes.ResultsAdjusted odds ratios show that those identified as frail have more than twice the risk (GFI, 2.62; TFI, 2.00; SPQ, 2,49) for developing disabilities compared to the non-frail group; those identified as frail by the TFI and SPQ have more than twice the risk of being admitted to a hospital. Sensitivity and specificity for development of disabilities are 71% and 63% (GFI), 62% and 71% (TFI) and 83% and 48% (SPQ). Regarding mortality, sensitivity for all tools are about 70% and specificity between 41% and 61%. For hospital admission, SPQ scores the highest for sensitivity (76%).ConclusionAll three instruments do have potential to identify older persons at risk, but their predictive power is not sufficient yet. Further research on these and other instruments is needed to improve targeting frail elderly.

It takes two to tango: the integration of people with disabilities into society

The concept of integration is not well defined. It not known how people with disabilities experience integration. In this study qualitative methods were used. The aim of the article is to define a model of successful integration based on the perspectives of people with disabilities and people within their social environment. Integration consists of five elements: functioning ordinarily without receiving special attention, mixing with others that are not disabled, taking part in society, trying to realize one’s potential and directing one’s own life. Integration is obtained through a process of interaction between a person with a disability and society. This process is influenced by personal, societal and support factors. The individual with a disability and society have a mutual responsibility with respect to integration.

Interventions to prevent disability in frail community-dwelling older persons: an overview

This narrative review was conducted to provide an overview of the variety of interventions aimed at disability prevention in community-dwelling frail older persons and to summarize promising elements. The search strategy and selection process found 48 papers that met the inclusion criteria. The 49 interventions described in these 48 papers were categorized into ‘comprehensive geriatric assessment’, ‘physical exercise’, ‘nutrition’, ‘technology’, and ‘other interventions’. There is a large diversity within and between the groups of interventions in terms of content, disciplines involved, duration, intensity, and setting. For 18 of the 49 interventions, significant positive effects for disability were reported for the experimental group. Promising features of interventions seem to be: multidisciplinary and multifactorial, individualized assessment and intervention, case management, long-term follow-up, physical exercise component (for moderate physically frail older persons), and the use of technology. Future intervention studies could combine these elements and consider the addition of new elements.

Effectiveness and implementation aspects of interventions for preventing falls in elderly people in long-term care facilities: a systematic review of RCTs

OBJECTIVES There is extensive literature on interventions to prevent or reduce falls in elderly people. These findings, however, were based mainly on studies of community-living persons. The primary aim of the present study was to report the effectiveness and implementation aspects of interventions aimed at reducing falls in elderly residents in long-term care facilities: a systematic review of randomized controlled trials (RCTs). DATA SOURCES MEDLINE, EMBASE, CINAHL, and hand searching of reference lists of included RCTs. REVIEW METHODS RCTs that assessed fall incidents (falls, fallers, recurrent fallers, fall-related injuries) among elderly residents in long-term care facilities were included in this narrative review. Two independent reviewers abstracted data: general program characteristics (setting, population, intervention program) and outcomes, detailed program characteristics (assessment, intervention content, individually tailored, multidisciplinary), and implementation aspects (feasibility, implications for practice). The CONSORT Statement 2001 Checklist was used regarding the quality of reporting RCTs. RESULTS Twenty trials met the inclusion criteria. Seven trials, 4 multifactorial and 3 monofactorial, showed a significant reduction in the fall rate, the percentage of recurrent fallers, or both the fall rate and the percentage of persons sustaining femoral fractures. The positive effective programs were as follows: a comprehensive structured individual assessment with specific safety recommendations; a multidisciplinary program including general strategies tailored to the setting and strategies tailored specifically to residents; a multifaceted intervention including education, environmental adaptation, balance, resistance training, and hip protector; calcium plus vitamin D supplementation; vitamin D supplementation; a clinical medication review; and a multifactorial intervention (fall risk evaluation, specific and general interventions). CONCLUSIONS In general, because of the limited number of included trials, the evidence is inconclusive for multifaceted and single interventions in long-term care facilities. Most of the reviewed studies did not find a significant positive effect on fall incidents. However, our data support the conclusions of Gillespie et al. that multifactorial interventions in long-term care populations seem more likely to be beneficial. However, single interventions (eg, targeting vitamin D insufficiency) can be effective. Furthermore, a careful approach is needed as programs to prevent falls in these settings may be ineffective or even may have adverse effects. This may occur especially when a program is not feasible for the setting in which it is implemented.
