There is a growing need for an integrated health information system to be used in community, institutional and hospital based settings. For example, changes in the structure, process and venues of service delivery mean that individuals with similar needs may be cared for in a variety of different settings. Moreover, as people make transitions from one sector of the healthcare system to another, there is a need for comparable information to ensure continuity of care and reduced assessment burden. The RAI/MDS series of assessment instruments comprise an integrated health information system because they have consistent terminology, common core items, and a common conceptual basis in a clinical approach that emphasizes the identification of functional problems.

BackgroundAims of the present study are the following: 1. to describe the rationale and methodology of the Services and Health for Elderly in Long TERm care (SHELTER) study, a project funded by the European Union, aimed at implementing the interRAI instrument for Long Term Care Facilities (interRAI LTCF) as a tool to assess and gather uniform information about nursing home (NH) residents across different health systems in European countries; 2. to present the results about the test-retest and inter-rater reliability of the interRAI LTCF instrument translated into the languages of participating countries; 3 to illustrate the characteristics of NH residents at study entry.MethodsA 12 months prospective cohort study was conducted in 57 NH in 7 EU countries (Czech Republic, England, Finland, France, Germany, Italy, The Netherlands) and 1 non EU country (Israel). Weighted kappa coefficients were used to evaluate the reliability of interRAI LTCF items.ResultsMean age of 4156 residents entering the study was 83.4 ± 9.4 years, 73% were female. ADL disability and cognitive impairment was observed in 81.3% and 68.0% of residents, respectively. Clinical complexity of residents was confirmed by a high prevalence of behavioral symptoms (27.5% of residents), falls (18.6%), pressure ulcers (10.4%), pain (36.0%) and urinary incontinence (73.5%). Overall, 197 of the 198 the items tested met or exceeded standard cut-offs for acceptable test-retest and inter-rater reliability after translation into the target languages.ConclusionThe interRAI LTCF appears to be a reliable instrument. It enables the creation of databases that can be used to govern the provision of long-term care across different health systems in Europe, to answer relevant research and policy questions and to compare characteristics of NH residents across countries, languages and cultures.

OBJECTIVE The aim of the study was to investigate how settings and registry characteristics affect the prevalence and nature of multimorbidity in elderly individuals. STUDY DESIGN AND SETTING We used data from three population-based studies, two general practitioner registries, one hospital discharge register, and one nursing home registry to estimate the prevalence of multimorbidity. Individuals aged 55 years and over were included. RESULTS Multimorbidity was most prevalent in nursing homes (82%), followed by the general population and general practitioner registries (56%-72%) and the hospital setting (22%). There were large differences in the nature of multimorbidity between settings. Combinations of hypertension, heart disease, and osteoarthritis were dominant in the population-based setting, whereas hypertension in combination with osteoarthritis, obesity, disorders of lipid metabolism, and diabetes dominated in the general practitioner setting. In the hospital setting, combinations of heart diseases had the highest prevalence. Combinations of dementia, hypertension, and stroke were dominant within the nursing home setting. CONCLUSION This study shows that setting and registry characteristics have an important influence on the outcome of multimorbidity studies. We recommend provision of at least information about the setting, the (list of) conditions included, the data collection method, and the time frame used, when reporting about the size and nature of multimorbidity.

Background and aims: Community care for older people is increasing dramatically in most European countries as the preferred option to hospital andlong-term care. While there has been a rapid expansion in Evidence-Based Medicine, apart from studies of specific interventions such as home visiting and hospital at home (specialist visits or hospital services provided to people in their own homes in the community), there is little evidence of characteristics of the recipients of community care services or the organisation of services that produce the best outcomes for them and their informal carers. The AdHOC Study was designed to compare outcomes of different models of community care using a structured comparison of services and a comprehensive standardised assessment instrument across 11 European countries. This paper describes the study and baseline data. Methods: 4,500 people 65 years and older already receiving home care services within the urban areas selected in each country were randomly sampled. They were assessed with the MDS-HC (Minimum Data Set-Home Care) instrument, containing over 300 items, including socio-demographic, physical and cognitive characteristics of patients as well as medical diagnoses and medications received. These data were linked to information on the setting, services structures and services utilization, including use of hospital and long-term care. After baseline assessment, patients were re-evaluated at 6 months with an abbreviated version of the instrument, and then at the end of one year. Data collection was performed by specially-trained personnel. In this paper, socio-demographics, physical and cognitive function and provision of hours of formal care are compared between countries at baseline. Results: The final study sample comprised 3,785 patients; mean age was 82±7.2 years, 74.2% were females. Marital and living status reflected close family relationships in southern Europe relative to Nordic countries, where 5 times as many patients live alone. Recipients of community care in France and Italy are characterised by very high physical and cognitive impairment compared with those in northern Europe, who have comparatively little impairment in Activities of Daily Living and cognitive function. The provision of formal care to people with similar dependency varies extremely widely with very little formal care in Italy and more than double the average across all levels of dependency in the UK. Conclusions: The AdHOC study, by virtue of the use of a common comprehensive standardised assessment instrument, is a unique tool in examining older recipients of community care services in European countries and their widely varied organisation. The extreme differences seen in dependency and hours of care illustrate the probable contribution the study will make to developing an evidence based on the structure, quantity and targeting of community care, which will have major policy implications.

&NA; There have been very few and limited cross‐national comparisons concerning pain among residents of long‐term care facilities in Europe. The aim of the present cross‐sectional study has been to document the prevalence of pain, its frequency and severity as well as its correlates in three European countries: Finland (north), Italy (south) and the Netherlands (western central). Patients (aged 65 years or above) were assessed with the Minimum Data Set 2.0 (MDS).The final sample comprised 5761 patients from 64 facilities in Finland, 2295 patients from 8 facilities in the Netherlands and 1959 patients from 31 facilities in Italy. The prevalence of pain – defined as any type of pain – varied between 32% in Italy, 43% in the Netherlands and 57% in Finland. In nearly 50% of cases, pain was present daily; there were no significant differences in pain prevalence between patients with cancer diagnosis and those with non‐cancer diagnosis. Regardless of the different prevalence estimates, pain was moderate‐to‐severe in over 50% of cases in all the countries. In multivariate logistic regression models, clinical correlates of pain were substantially similar across countries: pain was positively correlated with more severe physical disability (ADL impairment), clinical depression and a diagnosis of osteoporosis. Pain was negatively correlated with a diagnosis of dementia and more severe degrees of cognitive deterioration. We conclude that pain is frequently encountered in long‐term care facilities in Europe and that, despite cultural and case‐mix differences, pain speaks one language.

BACKGROUND many instruments are available to identify frail older adults who may benefit from geriatric interventions. Most of those instruments are time-consuming and difficult to use in primary care. OBJECTIVE to select a valid instrument to identify frail older adults in primary care, five simple instruments were compared. METHODS instruments included clinical judgement of the general practitioner, prescription of multiple medications, the Groningen frailty indicator (GFI), PRISMA-7 and the self-rated health of the older adult. Frieds frailty criteria and a clinical judgement by a multidisciplinary expert panel were used as reference standards. Data were used from the cross-sectional Dutch Identification of Frail Elderly Study consisting of 102 people aged 65 and over from a primary care practice in Amsterdam. In this study, frail older adults were oversampled. We estimated the accuracy of each instrument by calculating the area under the ROC curve. The agreement between the instruments and the reference standards was determined by kappa. RESULTS frailty prevalence rates in this sample ranged from 11.6 to 36.4%. The accuracy of the instruments ranged from poor (AUC = 0.64) to good (AUC = 0.85). CONCLUSION PRISMA-7 was the best of the five instruments with good accuracy. Further research is needed to establish the predictive validity and clinical utility of the simple instruments used in this study.

Large numbers of persons in most types of healthcare settings have palliative care needs that have considerable impact on their quality of life. Therefore, InterRAI, a multinational consortium of researchers, clinicians, and regulators that uses assessment systems to improve the care of elderly and disabled persons, designed a standardized assessment tool, the Resident Assessment Instrument for Palliative Care (RAI-PC). The RAI-PC can be used for both the design of individual care plans and for case mix and outcomes research. Some elements of this instrument are taken from the resident assessment instrument (RAI) mandated for use in all nursing homes in the United States and widely used throughout the world. The RAI-PC can be used alone or in conjunction with the other assessment tools designed by the InterRAI collaboration: the RAI for homecare (RAI-HC), for acute care (RAI-AC), and for mental health care (RAI-MH). The objective of this study was to field test and carry out reliability studies on the RAI-PC. After appropriate approvals were obtained, the RAI-PC instrument was field tested on 151 persons in three countries in more than five types of settings. Data obtained from 144 of these individuals were analyzed for reliability. The reliability of the instrument was very good, with about 50 percent of the questions having kappa values of 0.8 or higher, and the average kappa value for each of the eight domains ranging from 0.76 to 0.95. The 54 men and 95 women had a mean age of 79 years. Thirty-four percent of individuals suffered pain daily. Eighty percent tired easily; 52 percent were breathless on exertion; and 19 to 53 percent had one or more other symptoms, including change in sleep pattern, dry mouth, nausea and vomiting, anorexia, breathlessness at rest, constipation, and diarrhea. The number of symptoms an individual reported increased as the estimated time until death declined. The “clinician friendly” RAI-PC can be used in multiple sites of care to facilitate both care planning and case mix and outcomes research.

OBJECTIVES To determine modifiable factors related to abusive behaviors in nursing home residents with dementia. DESIGN Analysis of Minimum Data Set (MDS) of the Resident Assessment Instrument (RAI) information. SETTING We used MDS-RAI data from 8 Dutch nursing homes and 10 residential homes that volunteered to collect data for care planning. We included the data of residents within a 12-month time window for each facility separately, resulting in a range from April 4, 2007, to December 1, 2008. PARTICIPANTS We selected 929 residents older than 65 with Alzheimers disease or other dementia who were dependent in decision making and not comatose. MEASUREMENTS Cognitive Performance Scale, MDS Depression Scale and several individual items from the MDS-RAI (ability to understand others, verbally and physically abusive behavioral symptoms, resist care, diagnosis of Alzheimers disease and of dementia other than Alzheimers disease, diagnosis of depression, presence of delusions, hallucinations, pain frequency and constipation, and number of days receiving medications). RESULTS Resistiveness to care, related to lack of understanding, depression, hallucinations and delusions, was strongly related to abusive behaviors. Presence of depressive symptoms and delusions was also related to abusive behaviors independent of resistiveness to care. Only very few residents who understood others and were not depressed were abusive. CONCLUSION Abusive behaviors may develop from lack of understanding leading to resistiveness to care. Behavioral interventions preventing escalation of resistiveness to care into combative behavior and the treatment of depression can be expected to decrease or prevent abusive behavior of most nursing home residents with dementia.
