[Disease sequelae on function in persons 70 years and older and the acceptance of a new supporting network, the NetzWerk GesundAktiv (NWGA)]. / Funktionale Krankheitsfolgen von Menschen im Alter ab 70 Jahren und die Akzeptanz eines neuen Unterstützungs-Netzwerkes, das NetzWerk GesundAktiv (NWGA).

BACKGROUND: The growing need of nursing care as life expectancy increases is a problem. The Netzwerk AktivGesund (NWGA) tries to change this development in a positive way. In a pilot region of the city of Hamburg, persons 70 years and older were invited by their health insurance companies to participate in the NWGA supportive network. Results of the acceptance analysis are described here. METHODS: In order to focus on persons at risk of need for help functional competence was assessed by using the LUCAS functional ability index (selfreport questionnaire). In an explorative way, participants, refusers, persons interested (excluded due to high functional competence), and non-responders were compared in a retrospective observational study. Sociodemographic and routine data were used as ICD diagnoses from hospitalisations, number of contacts to physicians and level of need of nursing care during the 12 months before recruitment. RESULTS: There were 962 participants (7.4 %), 948 refusers (7.2 %), 2437 persons with interest (18.6 %) and 8753 non-responders (66.8 %) from the 13 100 persons contacted by mail. The sociodemographic factors differed between these groups. ICDs typical of older patients and ICD codes of functional impairment from the 5422 hospital stays showed different frequencies. Persons with interest had nearly no need of nursing care and the lowest level of morbidity. CONCLUSIONS: The results show that impairments of motoric and cognitive functions, in particular, and sociodemographic factors have impact on the acceptance of the NWGA. The recruitment for participation should be improved using approaches that are differentiated, respectively. Awareness of functional impairment as disease sequelae and pacemaker of need of nursing care, in general, might facilitate health promotion and prevention in older persons. An interest in preventative activities was remarkably frequent among the persons 70 years and older.

A randomized trial of effects of health risk appraisal combined with group sessions or home visits on preventive behaviors in older adults.

BACKGROUND: To explore effects of a health risk appraisal for older people (HRA-O) program with reinforcement, we conducted a randomized controlled trial in 21 general practices in Hamburg, Germany. METHODS: Overall, 2,580 older patients of 14 general practitioners trained in reinforcing recommendations related to HRA-O-identified risk factors were randomized into intervention (n = 878) and control (n = 1,702) groups. Patients (n = 746) of seven additional matched general practitioners who did not receive this training served as a comparison group. Patients allocated to the intervention group, and their general practitioners, received computer-tailored written recommendations, and patients were offered the choice between interdisciplinary group sessions (geriatrician, physiotherapist, social worker, and nutritionist) and home visits (nurse). RESULTS: Among the intervention group, 580 (66%) persons made use of personal reinforcement (group sessions: 503 [87%], home visits: 77 [13%]). At 1-year follow-up, persons in the intervention group had higher use of preventive services (eg, influenza vaccinations, adjusted odds ratio 1.7; 95% confidence interval 1.4-2.1) and more favorable health behavior (eg, high fruit/fiber intake, odds ratio 2.0; 95% confidence interval 1.6-2.6), as compared with controls. Comparisons between intervention and comparison group data revealed similar effects, suggesting that physician training alone had no effect. Subgroup analyses indicated favorable effects for HRA-O with personal reinforcement, but not for HRA-O without reinforcement. CONCLUSIONS: HRA-O combined with physician training and personal reinforcement had favorable effects on preventive care use and health behavior.

Decubitus ulcers: pathophysiology and primary prevention.

BACKGROUND: Pressure sores are a serious complication of multimorbidity and lack of mobility. Decubitus ulcers have become rarer among bed-ridden patients because of the conscientious use of pressure-reducing measures and increased mobilization. Nonetheless, not all decubitus ulcers can be considered preventable or potentially curable, because poor circulation makes some patients more susceptible to them, and because cognitive impairment can make prophylactic measures difficult to apply. METHODS: A systematic literature search was performed in 2004 and 2005 in the setting of a health technology assessment, and a selective literature search was performed in 2009 for papers on the prevention of decubitus ulcers. RESULTS: Elderly, multimorbid patients with the immobility syndrome are at high risk for the development of decubitus ulcers, as are paraplegic patients. The most beneficial way to prevent decubitus ulcers, and to treat them once they are present, is to avoid excessive pressure by encouraging movement. At the same time, the risk factors that promote the development of decubitus ulcers should be minimized as far as possible. CONCLUSIONS: Malnutrition, poor circulation (hypoperfusion), and underlying diseases that impair mobility should be recognized if present and then treated, and accompanying manifestations, such as pain, should be treated symptomatically. Over the patient's further course, the feasibility, implementation, and efficacy of ulcer-preventing measures should be repeatedly re-assessed and documented, so that any necessary changes can be made. Risk factors for the development of decubitus ulcers should be assessed at the time of the physician's first contact with an immobile patient, or as soon as the patient's condition deteriorates; this is a prerequisite for timely prevention. Once the risks have been assessed, therapeutic measures should be undertaken on the basis of the patient's individual risk profile, with an emphasis on active encouragement of movement and passive relief of pressure through frequent changes of position.

Social network assessment in community-dwelling older persons: results from a study of three European populations.

BACKGROUND AND AIMS: In clinical practice, the status of living alone is often used as the only measure describing an older person's social network. We evaluated whether additional use of a brief social network measure provides relevant additional information in relation to social support and engagement. METHODS: Cross-sectional survey of 6982 community- dwelling adults 65 years or older living in London, UK; Hamburg, Germany; and Solothurn, Switzerland. Data were collected using the self-administered multidimensional Health Risk Appraisal Questionnaire. Multivariate models were used to analyse adjusted correlations between the two measures of social network (living alone status, risk for social isolation with marginal family and friend network subscales) and potential consequences of inadequate social network (marginal emotional or instrumental support, lack of social engagement). RESULTS: Living alone status was more strongly associated with marginal instrumental support [OR=7.6 (95% CI 6.3, 9.1)] than with marginal emotional support [OR=4.2 (95% CI 3.4, 5.1)], and showed no statistically significant association with lack of social engagement [OR=0.9 (95% CI 0.8, 1.0)]. Risk of social isolation was more strongly related to marginal emotional support [OR=6.6 (95% CI 5.4, 8.0)] than to marginal instrumental support [OR=3.3 (95% CI 2.8, 4.0)], and was moderately related to lack of social engagement [OR=2.9 (95% CI 2.5, 3.4]. Marginal family and friend network subscales showed consistent and unique associations with social support and social engagement. CONCLUSION: Findings suggest that living alone status and a brief measure of social network identifies distinctive at-risk groups and potential pathways for intervention. Geriatric assessment programs including both social network measures may provide useful information about potentially modifiable social network risks in older persons.

Development, feasibility and performance of a health risk appraisal questionnaire for older persons.

BACKGROUND: Health risk appraisal is a promising method for health promotion and prevention in older persons. The Health Risk Appraisal for the Elderly (HRA-E) developed in the U.S. has unique features but has not been tested outside the United States. METHODS: Based on the original HRA-E, we developed a scientifically updated and regionally adapted multilingual Health Risk Appraisal for Older Persons (HRA-O) instrument consisting of a self-administered questionnaire and software-generated feed-back reports. We evaluated the practicability and performance of the questionnaire in non-disabled community-dwelling older persons in London (U.K.) (N = 1090), Hamburg (Germany) (N = 804), and Solothurn (Switzerland) (N = 748) in a sub-sample of an international randomised controlled study. RESULTS: Over eighty percent of invited older persons returned the self-administered HRA-O questionnaire. Fair or poor self-perceived health status and older age were correlated with higher rates of non-return of the questionnaire. Older participants and those with lower educational levels reported more difficulty in completing the HRA-O questionnaire as compared to younger and higher educated persons. However, even among older participants and those with low educational level, more than 80% rated the questionnaire as easy to complete. Prevalence rates of risks for functional decline or problems were between 2% and 91% for the 19 HRA-O domains. Participants' intention to change health behaviour suggested that for some risk factors participants were in a pre-contemplation phase, having no short- or medium-term plans for change. Many participants perceived their health behaviour or preventative care uptake as optimal, despite indications of deficits according to the HRA-O based evaluation. CONCLUSION: The HRA-O questionnaire was highly accepted by a broad range of community-dwelling non-disabled persons. It identified a high number of risks and problems, and provided information on participants' intention to change health behaviour.

Predicting the risk of hospital admission in older persons--validation of a brief self-administered questionnaire in three European countries.

OBJECTIVES: To validate the Probability of Repeated Admission (Pra) questionnaire, a widely used self-administered tool for predicting future healthcare use in older persons, in three European healthcare systems. DESIGN: Prospective study with 1-year follow-up. SETTING: Hamburg, Germany; London, United Kingdom; Canton of Solothurn, Switzerland. PARTICIPANTS: Nine thousand seven hundred thirteen independently living community-dwelling people aged 65 and older. MEASUREMENTS: Self-administered eight-item Pra questionnaire at baseline. Self-reported number of hospital admissions and physician visits during 1 year of follow-up. RESULTS: In the combined sample, areas under the receiver operating characteristic curves (AUCs) were 0.64 (95% confidence interval (CI)=0.62-0.66) for the prediction of one or more hospital admissions and 0.68 (95% CI=0.66-0.69) for the prediction of more than six physician visits during the following year. AUCs were similar between sites. In comparison, prediction models based on a person's age and sex alone exhibited poor predictive validity (AUC or= 0.5) were 2.3 times as likely (95% CI=2.1-2.6) as low-risk individuals to have a hospital admission, and 2.1 times as likely (95% CI=2.0-2.2) to have more than six physician visits. CONCLUSION: The Pra instrument exhibits good validity for predicting future health service use on a population level in different healthcare settings. Administrative data have shown similar predictive validity, but in practice, such data are often not available. The Pra is likely of high interest to governments and health insurance companies worldwide as a basis for programs aimed at health risk management in older persons.

[The Barthel Index in geriatrics. A context analysis for the Hamburg Classification Manual]. / Der Barthel-Index in der Geriatrie. Eine Kontextanalyse zum Hamburger Einstufungsmanual.

The Barthel Index (BI) is firmly established as an assessment instrument in geriatrics. It is a proven, clear and easy-to-use instrument for the recording of basic daily functions. However it is increasingly finding new applications beyond its original, clinically orientated use. It has been applied as a quality parameter, as an instrument for the management of service delivery provision and as an instrument to record treatment efforts relevant to care or costs. This study considers the basic suitability prerequisites of the Barthel Index for these applications.With the Hamburg Classification Manual for the BI, German geriatrics has made a contribution to the standardized operationalization of the items and to the standardized evaluation of aids. An evaluation was performed on a total of 5262 Barthel classifications at seven geriatric hospitals according to existing classification practice by comparison with 5483 classifications after introduction of the Hamburg Classification Manual. No significant differences were found in Barthel Index total scores either on admission or on discharge. With respect to further applications it is essential to be aware that the usability of the total score (including its changes over the course of time) is limited because of the ordinal scaling of the BI. Studies have been carried out which show how important this is, although they have so far received little attention. As a grading criterion the BI takes account not only of the "functional status" but also of the "extent of support effort". This can lead to positive changes in one focus -- especially with the use of aids -- without associated improvements in the other focus. Whether the BI in this form is meaningful for a specific application must be tested separately for each individual context. There is no justification for assuming that the BI has general validity irrespective of application. The results of a systematic literature survey on the testing quality criteria of the BI indicate an astonishingly generous approach to the question of the validity of the BI. Contrary to widespread opinion, cognitive-psychological components do influence the classification result of the BI. As an addition to the Hamburg Classification Manual we recommend that the extent of this influencing factor should also be more clearly operationalized and that "stimulation required" for the carrying out of an activity be included in the evaluation equivalent to the factor "supervision required" already introduced by Barthel and Mahoney. The BI has shown itself to be an efficient but nonetheless multidimensional global parameter in clinical practice, whose meaningfulness is on the level of the individual item and whose validity, particularly as total score and course parameter, needs to be proven for each new application. The Hamburg Classification Manual, as a standardized and consensus-based operationalization of the BI, provides an important basis for this.
