Non malignant daily pain and risk of disability among older adults in home care in Europe.

Aim of the present observational study was to evaluate the association between daily pain and incident disability in elderly subjects living in the community. We used data from the AgeD in HOme Care (AD-HOC) project, a 1 year longitudinal study enrolling subjects aged 65 or older receiving home care in 11 European countries. Daily pain was defined as any type of pain or discomfort in any part of the body manifested every day in the seven days before the baseline assessment. Disability performing activities of daily living (ADLs) was defined as the need of assistance in 1 or more of the following ADL: eating, dressing, transferring, mobility in bed, personal hygiene and toileting. Mean age of 1520 subjects participating the study was 82.1 (standard deviation 6.9) years, and 1178 (77.5%) were women and 695 (45.7%) reported daily pain at the baseline assessment. Overall, 123/825 participants (19.0%) with daily pain and 132/695 (14.9%) without daily pain reported incident disability during the 1 year follow up of the study. After adjustment for potential confounders, participants with daily pain had a significantly higher risk of developing disability, compared with other participants (hazard ratio 1.36; 95% CI: 1.05-1.78). The risk of disability increased with pain severity and with number of painful sites. In conclusion among old subjects living in the community, daily pain is associated with an increased risk of disability.

Proposal of a service delivery integration index of home care for older persons: application in several European cities.

PURPOSE: To propose an integration index of home care delivery to older persons, to study its validity and to apply it to home care services of European cities. THEORY: Home care delivery integration was based on two dimensions referring to process-centred integration and organisational structure approach. METHOD: Items considered as part of both dimensions according to an expert consensus (face validity) were extracted from a standardised questionnaire used in "Aged in Home care" (AdHoc) study to capture basic characteristics of home care services. Their summation leads to a services' delivery integration index. This index was applied to AdHoc services. A factor analysis was computed in order to empirically test the validity of the theoretical constructs. The plot of the settings was performed. RESULTS: Application of the index ranks home care services in four groups according to their score. Factor analysis identifies a first factor which opposes working arrangement within service to organisational structure bringing together provisions for social care. A second factor corresponds to basic nursing care and therapies. Internal consistency for those three domains ranges from 0.78 to 0.93. When plotting the different settings different models of service delivery appear. CONCLUSION: The proposed index shows that behind a total score several models of care delivery are hidden. Comparison of service delivery integration should take into account this heterogeneity.

Prevalence and predictors of influenza vaccination among frail, community-living elderly patients: an international observational study.

The annual winter outbreak of influenza is one of the major cause of morbidity and mortality among frail elderly people. The aim of the present study was to identify prevalence and predictors of influenza vaccination in a large European population of frail and old people living in community. This was an observational study conducted in 11 European countries. We enrolled 3878 people 65 years and older already receiving home care services within the urban areas. All participants were assessed with the Minimum Data Set-Home Care (MDS-HC) instrument containing over 300 items, including socio-demographic, physical and cognitive characteristics of patients as well as medical diagnoses and medications received. A single question about the influenza vaccination status was used. The rate of influenza vaccination was around 59% of the studied sample. Significant geographical variations were evident in the prevalence of vaccination ranging from 31% of Prague (Czech Republic) to 88% of Rotterdam (The Netherlands). Overall, persons living alone were less likely to receive influenza vaccine as compared with those living with an informal caregiver (OR, 0.78; 95% CI 0.67-0.90). Similarly, cognitive impairment and presence of economic problems were associated with a lower likelihood of being vaccinated (OR: 0.69, 95% CI 0.59-0.80 and OR, 0.58; 95% CI 0.45-0.74, respectively). On the other hand, old age and comorbidity were associated with an higher probability of being vaccinated. In conclusion, more than 40% of subjects in this sample of home care patients in Europe did not receive influenza vaccination. Recommendations for influenza vaccination have not been adequately implemented.

Potentially inappropriate medication use among elderly home care patients in Europe.

CONTEXT: Criteria for potentially inappropriate medication use among elderly patients have been used in the past decade in large US epidemiological surveys to identify populations at risk and specifically target risk-management strategies. In contrast, in Europe little information is available about potentially inappropriate medication use and is based on small studies with uncertain generalizability. OBJECTIVE: To estimate the prevalence and associated factors of potentially inappropriate medication use among elderly home care patients in European countries. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cross-sectional study of 2707 elderly patients receiving home care (mean [SD] age, 82.2 [ 7.2] years) representatively enrolled in metropolitan areas of the Czech Republic, Denmark, Finland, Iceland, Italy, the Netherlands, Norway, and the United Kingdom. Patients were prospectively assessed between September 2001 and January 2002 using the Minimum Data Set in Home Care instrument. MAIN OUTCOME MEASURES: Prevalence of potentially inappropriate medication use was documented using all expert panels criteria for community-living elderly persons (Beers and McLeod). Patient-related characteristics independently associated with inappropriate medication use were identified with a multiple logistic regression model. RESULTS: Combining all 3 sets of criteria, we found that 19.8% of patients in the total sample used at least 1 inappropriate medication; using older 1997 criteria it was 9.8% to 10.9%. Substantial differences were documented between Eastern Europe (41.1% in the Czech Republic) and Western Europe (mean 15.8%, ranging from 5.8% in Denmark to 26.5% in Italy). Potentially inappropriate medication use was associated with patient's poor economic situation (adjusted relative risk [RR], 1.96; 95% confidence interval [CI], 1.58-2.36), polypharmacy (RR, 1.91; 95% CI, 1.62- 2.22), anxiolytic drug use (RR, 1.82; 95% CI, 1.51-2.15), and depression (RR, 1.29; 95% CI, 1.06-1.55). Negatively associated factors were age 85 years and older (RR, 0.78; 95% CI, 0.65-0.92) and living alone (RR, 0.76; 95% CI, 0.64-0.89). The odds of potentially inappropriate medication use significantly increased with the number of associated factors (P<.001). CONCLUSIONS: Substantial differences in potentially inappropriate medication use exist between European countries and might be a consequence of different regulatory measures, clinical practices, or inequalities in socioeconomic background. Since financial resources and selected patient-related characteristics are associated with such prescribing, specific educational strategies and regulations should reflect these factors to improve prescribing quality in elderly individuals in Europe.

The AdHOC Study of older adults' adherence to medication in 11 countries.

OBJECTIVE: Authors investigated, cross-nationally, the factors, including demographic, psychiatric (including cognitive), physical, and behavioral, determining whether older people take their prescribed medication. Older adults are prescribed more medication than any other group, and poor adherence is a common reason for non-response to medication. METHODS: Researchers interviewed 3,881 people over age 65 who receive home care services in 11 countries, administering a structured interview in participants' homes. The main outcome measure was the percentage of participants not adherent to medication. RESULTS: In all, 12.5% of people (N=456) reported that they were not fully adherent to medication. Non-adherence was predicted by problem drinking (OR=3.6), not having a doctor review their medication (OR=3.3), greater cognitive impairment (OR=1.4 for every one-point increase in impairment), good physical health (OR=1.2), resisting care (OR=2.1), being unmarried (OR=2.3), and living in the Czech Republic (OR=4.7) or Germany (OR=1.4). CONCLUSION: People who screen positive for problem drinking and who have dementia (often undiagnosed) are less likely to adhere to medication. Therefore, doctors should consider dementia and problem drinking when prescribing for older adults. Interventions to improve adherence in older adults might be more effective if targeted at these groups. It is possible that medication-review enhances adherence by improving the doctor-patient relationship or by emphasizing the need for medications.

Association between pain and depression among older adults in Europe: results from the Aged in Home Care (AdHOC) project: a cross-sectional study.

OBJECTIVE: To assess the association between pain and depression in a population of older adults. METHOD: We conducted a cross-sectional study using data from the Aged in Home Care (AdHOC) database, which contains information on older adults receiving home care services in 11 European countries from 2001 to 2003. Pain was defined as any type of pain or discomfort manifested over the 7 days preceding the assessment. Depression was defined as a score >or= 3 on the Minimum Data Set Depression Rating Scale. RESULTS: Mean age of 3976 subjects entering the study was 82.3 years, and 2948 (74.1%) were women. Of the total sample, 2380 subjects presented with pain (59.9%), but its prevalence differed substantially among countries. Depression was diagnosed in 181 (11.3%) of the 1596 participants without pain and in 464 (19.5%) of the 2380 participants with pain (p < .001). After adjusting for potential confounders, pain was significantly associated with depression (odds ratio [OR] 1.76, 95% confidence interval [CI] = 1.43 to 2.17). This association seemed to be modified by sex. Compared to male participants without pain, women with pain were significantly more likely to present with depression (OR = 1.77; 95% CI = 1.29 to 2.42), while no significant difference was observed for women without pain (OR = 0.86; 95% CI = 0.61 to 1.22) and men with pain (OR = 1.24; 95% CI = 0.86 to 1.79). Among women, the association of pain and depression became progressively more pronounced as pain severity, pain frequency, and number of painful sites increased. CONCLUSION: This study documented that in a large sample of older adults living in the community, pain is associated with depression, especially among women.

Community care in Europe. The Aged in Home Care project (AdHOC).

BACKGROUND AND AIMS: Community care for older people is increasing dramatically in most European countries as the preferred option to hospital and long-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.

Understanding the roles of registered general nurses and care assistants in UK nursing homes.

BACKGROUND: The recent government decision to fund the costs of Registered nursing time in long-term care facilities in England through the Registered Nurse Contribution to Care renders the need to distinguish the role of Registered General Nurses (RGNs) from that of Care Assistants (CAs) in nursing homes increasingly important. AIM: The objective of this qualitative study was to obtain an in-depth understanding of the main differences between the roles and functions of RGNs and CAs working in nursing homes in the United Kingdom (UK). DESIGN: Data were collected through interviews with nine RGNs and 12 CAs employed in four different nursing homes across England. FINDINGS: Our findings suggest that RGNs have difficulty defining and limiting their roles because they have all-embracing roles, doing everything and anything within the home. By contrast, CAs define their role in terms of what they are not allowed to do. This difficulty in limiting their role, in addition to their sense of professional accountability for residents' care, leads RGNs to experience difficulty in delegating tasks to CAs. Both RGNs and CAs agreed that an increase in the number of assistive staff is needed to provide residents with good quality care and suggested that a measure of resident dependency would be a good method by which to determine staffing levels. CONCLUSIONS: We recommend that job descriptions that clearly define the roles and responsibilities of both RGNs and CAs are developed so that caregivers at all levels understand each others' roles and work together to co-ordinate, plan and provide residents' care.

Identification of registered nursing care of residents in English nursing homes using the Minimum Data Set Resident Assessment Instrument (MDS/RAI) and Resource Utilisation Groups version III (RUG-III).

AIM: to determine if a combination of Minimum Data Set/Resident Assessment Instrument (MDS/RAI) assessment variables and the Resource Utilisation Groups version III (RUG-III) case-mix system could be used as a method of identifying and reimbursing registered nursing care needs in long-term care. METHOD: the sample included 193 nursing home residents from four nursing homes from three different locations and care providers in England. The study included assessments of residents' care needs using either the MDS/RAI assessments or RUG stand-alone questionnaires and a time study that recorded the amount of nursing time received by residents over a 24-h period. Validity of RUG-III for explaining the distribution of care time between residents in different RUG-III groups was tested. The difference in direct and indirect care provided by registered general nurses (RGN) and care assistants (CA) to residents in RUG-III clinical groups was compared. RESULTS: the RUG-III system explained 56% of the variance in care time (Eta2, P=0.0001). Residents in RUG-III groups associated with particular medical and nursing needs (enhanced RGN care) received more than twice as much indirect RGN care time (t-test, P<0.001) and 1.4 times as much direct RGN and direct CA time (t-test, P<0.01) than residents with primarily cognitive impairment or physical problems only (standard RGN care). Residents with enhanced RGN care received an average of 48.1 min of RGN care in 24 h (95% CI 4.1-55.2) compared with an average of 31.1 min (95% CI 26.8-35.5) for residents in the standard RGN care group. A third low RGN care group was created following publication of the Department of Health guidance on NHS Funded Nursing Care. With three levels, the enhanced care group receives about 38% more than the standard group, and the low group receives about 50% of the standard group. CONCLUSIONS: the RUG-III system effectively differentiated between nursing home residents who are receiving 'low', 'standard' and 'enhanced' RGN care time. The findings could provide the basis of a reimbursement system for registered nursing time in long-term care facilities in the UK.
