Grading gems: Appraising the quality of research about social work and social care.

The impetus towards basing practice and policy decisions more explicitly on sound research requires tools to facilitate the systematic appraisal of the quality of research encompassing a diverse range of methods and designs. Five exemplar tools were developed and assessed in terms of their usefulness in selecting studies for inclusion in a systematic review. The widely used ‘hierarchy of evidence’ was adapted and used to appraise internal validity. Four tools were then developed to appraise the external validity dimensions of generalizability (two scales) and methods of data collection (two scales). Methods of combining the scores generated by each tool were explored. Qualitative and quantitative studies were appraised, not separated into two spheres but by using complementary tools developed to appraise different aspects of rigour. There was a high level of agreement between researchers in applying the tools to twenty-two studies on decision making by professionals about the longterm care of older people. The scales for internal validity and generalizability discriminated between the qualities of studies appropriately. The two tools to appraise data collection gave diverse results. Excluding studies that scored in the lowest category on any scale appeared to be the scoring system that was most justifiable. This approach is presented to stimulate debate about the practical application of the evidence-based initiative to social work and social care. This study may assist in developing clearer definitions and common language about appraising rigour that should further the process of selecting robust research for synthesis to inform practice and policy decisions.

Systematically retrieving research – a case study evaluating seven databases.

Objective: Developing the scientific underpinnings of social welfare requires effective and efficient methods of retrieving relevant items from the increasing volume of research. Method: We compared seven databases by running the nearest equivalent search on each. The search topic was chosen for relevance to social work practice with older people. Results: Highest sensitivity was achieved by Medline (52%), Social Sciences Citation Index (46%) and Cumulative Index of Nursing and Allied Health Literature (CINAHL) (30%). Highest precision was achieved by AgeInfo (76%), PsycInfo (51%) and Social Services Abstracts (41%). Each database retrieved unique relevant articles. Conclusions: Comprehensive searching requires the development of information management skills. The social work profession would benefit from having a dedicated international database with the capability and facilities of major databases such as Medline, CINAHL, and PsycInfo.

Compression therapy in leg ulcer management

Led ulcer management is an important consideration for all nurses involved in the care of older people. Non-specialists in tissue viability might not always be aware of the evidence base for best practice. The authors examine the effectiveness of multi-layer and single-layer long or short stretch bandage systems in leg ulcer management.

Agricultura urbana, condición para el desarrollo sostenible y la mejora del paisaje

Este artículo resulta de investigaciones en torno al “enverdecimiento” de las ciudades y las oportunidades de la agricultura urbana para la alimentación de una población en constante aumento que no trabaja la tierra. También es fruto de actividades de mejora de ambientes urbanos realizadas con la Escuela de Ingenieros Agrónomos de la Universidad Politécnica de Madrid. A través de casos de agricultura urbana, entendiendo por ella el conjunto de prácticas para la producción de alimentos y plantas ornamentales dentro de las ciudades y en sus entornos, se analizan alternativas para la recuperación de espacios construidos e incremento de la calidad de vida de la población. Todo ello se traduce, además, en creación de riqueza y mejora del paisaje urbano, siempre desde criterios de sostenibilidad que favorecen el desarrollo local desde la Cumbre de la Tierra de Río de 1992 y la Conferencia sobre Desarrollo Sostenible Río+20 de 2013.

40 years is an awful long time

ABSTRACT: Older people who are caring for their adult sons and daughters with disabilities are under tremendous stress because they may suffer health problems themselves; have financial problems due a lifetime of caring; may have to care on their own due to the death of their spouse; worry about the future care of their child; and may feel uncomfortable approaching professionals for help. Professionals working with these families need to take contextual pressures into consideration when planning intervention. Twenty-nine parents of 27 adults with intellectual and/or developmental disabilities (including autism) were asked about present care and service arrangements, health issues, family support, and “futures planning.” The research reported here identifies complex networks of relationships. Virtual absence of structured futures planning was one of the key issues. Recommendations are made for professionals working in this field.

An Assessment of Sheltered Housing Design in Belfast, Northern Ireland

This article presents a UK-based research that has studied the existing sheltered or assisted living housing population and its future housing options and preferences. This meets an identified need to know and understand users' needs and requirements in much more detail that outlines what is liked and disliked by older people about sheltered housing, so that those who plan and design such housing can be aware of their views. The study also sought to understand the architects' challenges in designing and adapting this type of housing. The sheltered housing managed by housing associations in Belfast, Northern Ireland, was assessed through a series of site visits, structured interviews, and a focus group with stakeholders. Findings revealed older users' keen interest in participating in their housing needs assessment, identified building design concerns and provided recommendations for potential design guidelines. The findings of this research have provided important policy and design guidance to NI housing providers, and also allowed various stakeholders to participate in the debate about the quality of housing provided for the older people. This is a significant research study that generated considerable interest from various housing providers. This is an international peer reviewed journal.

Factors influencing eating a varied diet in old age

OBJECTIVE:
To investigate the influences of resources and food-related goals on the variety of food choice among older people.
DESIGN:
A questionnaire-based survey in eight European countries: Poland, Portugal, United Kingdom, Germany, Sweden, Denmark, Italy and Spain.
SUBJECTS:
Participants (n 3200) were above 65 years of age and living in their own homes. The samples were quota samples, eight groups of fifty in each country, based on gender, age and living circumstances, reflecting the diversity of each of the national populations based on education, income and urbanization of living environment.
RESULTS:
Hierarchical multiple regression analysis showed that income, health status, access to a car and living arrangement affected the level of dietary variety. The perceived level of different food-related resources impacted the consumption of a varied diet over and above actual resource levels. Food-related goals contributed to variety of food intake that was not accounted for by the amount of material resources possessed or the social and other resources perceived to be possessed.
CONCLUSIONS:
Older people's variety of food intake depended on material resources (e.g. monthly income, access to a car, living arrangement, physical and mental health). However, in addition to these variables, the way older people perceived other resources, such as their level of appetite, their food knowledge, their perception of the distance to the shops, access to high-quality products, having better kitchen facilities, access to good service providers and support from friends and neighbours, all contributed to how varied a diet they ate.

Willingness to use functional breads. Applying the Health Belief Model across four European countries

The present study focused on the role of the Health Belief Model (HBM) in predicting willingness to use functional breads, across four European countries: UK (N = 552), Italy (N = 504), Germany (N = 525) and Finland (N = 513). The behavioural evaluation components of the HBM (the perceived benefits and barriers conceptualized respectively as perceived healthiness and pleasantness) and the health motivation component were good predictors of willingness to use functional breads whereas threat perception components (perceived susceptibility and perceived anticipated severity) failed as predictors. This result was common in all four countries and across products. The role of 'cue to action' was marginal. On the whole the HBM fit was similar across the countries and products in terms of significant predictors (the perceived benefits, barriers and health motivation) with the exception of self-efficacy which was significant only in Finland. Young consumers seemed more interested in the functional bread with a health claim promoting health rather than in reducing risk of disease, whereas the opposite was true for older people. However, functional staple foods, such as bread in this European study, are still perceived as common foods rather than as a means of avoiding diseases. Consumers seek these foods for their healthiness (the perceived benefits) as they expect them to be healthier than regular foods and for the pleasantness (the perceived barriers) as they do not expect any change in the sensory characteristics due to the addition of the functional ingredients. The importance of health motivation in willingness to use products with health claims implies that there is an opening for developing better models for explaining health-promoting food choices that take into account both food and health-related factors without making a reference to disease-related outcome.

The impact of personal resources and their goal relevance on satisfaction with food-related life among the elderly.

The study explored how actual resources, perceived levels of different types of resources and goal relevance of these resources affect older people's satisfaction with food-related life using a survey in eight European countries, where 3291 participants above 65 years of age and living in their own homes took part. Satisfaction with food-related life was measured using Satisfaction With Food-related Life (SWFL) scale developed by Grunert, Raats, Dean, Nielsen, Lumbers and The Food in Later Life Team. [(2007). A measure of satisfaction with food-related life. Appetite, 49, 486–493]. Results showed that older people rated the resources that they believed to have plentiful of as being highly relevant to achieve their goals. The individuals who rated the relevance and their level of different resources as high were also more satisfied with their food-related quality of life. Further, satisfaction with food-related life, as was expected, was predicted by income, health measures and living circumstances. However, the study also showed that perceived levels of other resources such as support of family and friends, food knowledge, storage facilities also added to the individuals’ satisfaction with food-related life. In addition, the congruence between perceived level and relevance of a resource was also shown to add to people's satisfaction with food-related life, implying that older people's satisfaction with food-related life depends not only on the level of resources they think they have but also on their goals and how important they think these resources are to achieving their goals.

Apolipoprotein E genotype is associated with macular pigment optical density.

PURPOSE: Age-related macular degeneration (AMD) is the most common cause of blindness in older people in developed countries, and risk factors for this condition may be classified as genetic and environmental. Apolipoprotein E is putatively involved in the transport of the macular pigment (MP) carotenoids lutein (L) and zeaxanthin (Z) in serum and may also influence retinal capture of these compounds. This study was designed to investigate the relationship between macular pigment optical density (MPOD) and ApoE genotype. METHODS: This was a cross-sectional study of 302 healthy adult subjects. Dietary intake of L and Z was assessed by food frequency questionnaire, and MPOD was measured by customized heterochromatic flicker photometry. Serum L and Z were measured by HPLC. ApoE genotyping was performed by direct polymerase chain reaction amplification and DNA nucleotide sequencing from peripheral blood. RESULTS: Genotype data were available on 300 of the 302 (99.3%) subjects. The mean (+/- SD) age of the subjects in this study was 47.89 +/- 11.05 (range, 21-66) years. Subjects were classed into one of three ApoE genotype groups, as follows: group 1, epsilon2epsilon2 or epsilon2epsilon3; group 2, epsilon3epsilon3; group 3, epsilon2epsilon4 or epsilon3epsilon4 or epsilon4epsilon4. All three groups were statistically comparable in terms of age, sex, body mass index, cigarette smoking, and dietary and serum levels of L and Z. There was a statistically significant association between ApoE genotype and MPOD. Subjects who had at least one epsilon4 allele had a higher MPOD across the macula than subjects without this allele (group 1 MPOD area, 0.70 +/- 0.40; group 2 MPOD area, 0.67 +/- 0.42; group 3 MPOD area, 0.85 +/- 0.46; one-way ANOVA, P = 0.014. CONCLUSIONS: These results suggest that ApoE genotype status is associated with MPOD. This association may explain, at least in part, the putative protective effect of the epsilon4 allele for AMD and is consistent with the view that apolipoprotein profile influences the transport and/or retinal capture of circulating L and/or Z.

Risks to home care workers: Professional perspectives

Care at home is fundamental to community care policy, but the simultaneous growth of health and safety regulation has implications for home care services because of the duty of employers towards home care workers. This grounded theory study set in Northern Ireland used data from 19 focus groups and nine semi-structured interviews with a range of health and social services professionals and managers to explore perspectives on planning long term care for older people. Home care workers faced a wide range of hazards in the homes of clients, who themselves were faced with adapting their living habits due to their changing health and care needs and 'risks.' Creative approaches were used to ensure the health and safety of home care workers and simultaneously to meet the choices of clients. Staff experienced feelings of conflict when they judged it necessary to impose their way of providing home care and thus impose their values on clients to create a safe working environment. There was variation between and within organizations in terms of the staff focus on client needs or on their employer responsibility towards home care workers. The planning of home care services must take account of both the choices of clients and the hazards facing home care staff.

UK Food Standards Agency Workshop Report: Diet and Immune Function

The UK Food Standards Agency convened a workshop on 13 May 2009 to discuss recently completed research on diet and immune function. The objective of the workshop was to review this research and to establish priorities for future research. Several of the trials presented at the workshop showed some effect of nutritional interventions (e.g. vitamin D, Zn, Se) on immune parameters. One trial found that increased fruit and vegetable intake may improve the antibody response to pneumococcal vaccination in older people. The workshop highlighted the need to further clarify the potential public health relevance of observed nutrition-related changes in immune function, e.g. susceptibility to infections and infectious morbidity.

Understanding Old Age and Victimisation: A Critical Exploration

Purpose – The purpose of paper is to shine light on the under-theorised relationship between old age and victmisation. In classical criminological studies, the relationship between “age”, victimisation and crime has been dominated by analysis of younger people's experiences. This paper aims to address this knowledge deficit by exploring older people's experiences by linking it to the social construction of vulnerability.

Design/methodology/approach – The paper explores both historical and contemporary narratives relating to the diverse experiences of older people as victims in the UK. In particular, from 1945 to the present, statistical context and theoretical advancement illuminates that older people as a social group have a deep “fear of crime” to their relative victimisation.

Findings – A careful survey of the criminological literature highlights a paucity of research relating to older people's views and experiences of crime and victimisation. The conceptual issue of vulnerability in different contexts is important in understanding ageing and victimisation in UK. The paper's findings illustrate that their experiences have remained marginalised in the debates around social policy, and how the criminal justice system responds to these changes remains yet to be seen.

Research limitations/implications – Any research attempt at theorising “age” should take into consideration not just younger people, but also the diverse experiences of older people. Policy makers may care to ponder that benchmarks be written that takes into full consideration of older people's experiences as vulnerability.

Practical implications – For criminal justice scholars and practitioners, there is a need to listen to the narratives of older people that should help shape and frame debate about their lived experiences. There should be an examination of existing formal and informal practices regarding elders, as the first step in developing an explicit and integrated set of policies and programmes to address the special needs of this group.

Originality/value – This is an original paper in highlighting how important old age is in construction of “victims” in modern society. By theorising age, victimisation and crime it is hoped to dispel and challenge some of the myths surrounding later life, crime and the older victim.
