The prevalence of falls in adults aged 40 years or older in an urban, German population. Results from a telephone survey.

BACKGROUND: Single or frequent falls lead to increased morbidity due to fall-related injury, fear of falling, impairments in quality of life and loss of independence. To assess the impact of falls, prevalence data are essential. METHODS: In 2006, a telephone survey was performed in a random sample of 1270 inhabitants of the city of Herne, Germany, aged 40 years or older. Participants were asked about falls during the previous 4 weeks and 6 and 12 months, respectively. A fall was defined as an unexpected event in which the individual comes to rest on the ground, floor or a lower level. Participants were also asked about pain and whether or not a medical diagnosis of osteoporosis had ever been made. Standardized prevalences and odds ratios (OR) with 95 % confidence interval are reported. RESULTS: In total, 862 (67.9 %) adults participated. Participants were significantly older than non-participants and more often female than male. Prevalences standardized for the population of Herne for at least one fall within the previous 4 weeks or 12 months or two or more falls within 12 months, respectively, were 3.1 %, 12.1 %, and 4.5 %. Women were more often affected than men. A total of 2.3 % participants reported both at least one fall and a medical diagnosis of osteoporosis. The prevalence of falls increased with increasing age and was also related to musculoskeletal pain. CONCLUSIONS: Our estimates indicate that single and multiple falls affect a substantial proportion of adults in the urban population. Risk groups such as older adults and females with osteoporosis might represent a target group when considering measures for fall prevention.

An exercise programme for community-dwelling, mobility-restricted and chronically ill older adults with structured support by the general practitioner's practice (HOMEfit). From feasibility to evaluation.

Programmes containing health-enhancing physical exercise should be evaluated using standards that are just as rigorous as those required for drug development. In contrast to new medicines, exercise programmes are highly complex. This has to be taken into account when designing the research plan. In order to illustrate the development process of a "complex intervention", we use the example of an exercise programme for community-dwelling, mobility-restricted and chronically ill older adults. Based on a framework for evaluation of complex interventions (Medical Research Council [MRC], UK), a research plan was set up containing the phases: development, feasibility, evaluation, implementation. The development phase resulted in the design of a home-based exercise programme in which the target group is approached and supported via their general practitioner and an exercise therapist. A feasibility study was performed. Three quantitative criteria for feasibility (adoption, safety, continuing participation) were statistically confirmed which permitted the decision to proceed with the research plan. So far, the MRC framework has proved to be valuable for the development of the new programme.

[Measurement of physical activity in older adults. Correlation between the PRISCUS-PAQ and accelerometry]. / Messung körperlicher Aktivität bei älteren Erwachsenen. Übereinstimmung zwischen PRISCUS-PAQ und Akzelerometrie.

BACKGROUND: The German questionnaire PRISCUS-PAQ was developed to measure actual physical activity of older adults in a telephone interview. PRISCUS-PAQ consists of ten main questions to assess the time spend in domestic activities (e.g., housework, gardening), sporting activities (e.g., riding a bicycle), and inactivity (e.g., sedentary activity, sleeping during the day) during the prior week. By assessing the number of days for each activity and the mean duration of performing this activity, a total score can be calculated. The total score corresponds to the energy consumption for 1 week. The aim of this study is to estimate the correlation of the PRISCUS-PAQ total score and accelerometry as an objective measurement method for the assessment of physical activity. MATERIAL AND METHODS: A total of 114 participants (58% women) with a mean age of 76 years participated in the study. PRISCUS-PAQ was initially analyzed descriptively. To assess the validity of PRISCUS-PAQ, the correlation (correlation coefficient of Spearman) was calculated between the total score of the questionnaire PRISCUS-PAQ and the 95% trimmed sum of an accelerometer with a measurement period of 1 week. RESULTS: The correlation coefficient for the association of the PRISCUS-PAQ total score and the 95% trimmed sum of the acceleration values was r = 0.28 (95% confidence interval 0.10­0.44). Activities of daily life like cleaning and other domestic activities highly contributed to the weekly energy consumption of the participants. CONCLUSION: The association between the PRISCUS-PAQ questionnaire and accelerometry measured physical activity is comparable to other validated and established international questionnaires. The PRISCUS-PAQ is the first German questionnaire that allows the measurement of physical activity of older adults in a telephone interview.

[Back pain, pain therapy and satisfaction with therapy--analyses in a cohort of elderly primary health care patients (getABI)]. / Rückenschmerz, Schmerztherapie und Therapiezufriedenhei--Analyse einer Kohorte älterer Hausarztpatienten (getABI).

INTRODUCTION: Back pain can affect quality of life and independence of elderly people. The goal of this study was to determine the prevalence of back pain in a cohort of elderly primary health care patients, as well as to analyse pain therapy and level of satisfaction with therapy. METHODS: In a monitored prospective cohort study (German epidemiological trial on ankle brachial index, getABI), 6 880 unselected patients aged 65 years and above have been followed up by 344 representative primary care physicians in Germany since October 2001. In the 5-year follow-up, 2 120 patients (median age 76; 70-94 years; 53.7% women) were interviewed by telephone about location and intensity of pain during the past 3 months, about impairment due to pain, about pain therapy and satisfaction with therapy. RESULTS: Of the 2 095 patients who answered the questions on pain, 803 (38.3%) had suffered from pain of the upper and/or lower back within the past 3 months. The prevalence of back pain was higher in female than in male patients (45.0% vs. 30.6%; p<0.05). In about half of the men and half of the women with back pain, the back was also the main pain region. This subsample (n=409) with the back as main pain region (BMP) was analysed in more detail. The mean "von Korff intensity score" (scale 0-100) was 46.5±19.9, the mean "von Korff impairment score" (scale 0-100) was 23.6±23.0. Women reported a higher mean intensity of back pain than men (48.8±20.0 vs. 42.4±19.3; p<0.05) and complained about a higher pain-related impairment (26.2±23.5 vs. 19.2±21.5; p<0.05). Of all BMP patients, 253 (61.9%) visited a physician (at least once) during the past 3 months due to pain. The treatments most frequently applied (multiple answers permitted) were: oral medication (62.5%), injections (38.6%), and physiotherapy (35.9%). Patients (n=224) were asked to rate the therapy on a scale from 1 to 6 (1 being the highest grade). The mean rating was 3.1±1.4. 36.8% were not satisfied with pain relief. 61.4% wished for a considerable improvement of their pain therapy. CONCLUSION: The prevalence of back pain in elderly people is high and leads to functional limitations. As a consequence of the rather low mean satisfaction with pain therapy, future studies on back pain therapy should include an assessment of patient preferences and satisfaction with therapy. It remains questionable, if the current medical care for elderly people with back pain complies with the latest guidelines that demand for multimodal therapy.

[Prerequisites for a new health care model for elderly people with multiple morbidities: results and conclusions from 3 years of research in the PRISCUS consortium]. / Voraussetzungen für ein neues Versorgungsmodell für ältere Menschen mit Multimorbidität: Ergebnisse und Schlussfolgerungen aus 3-jähriger Forschung im PRISCUS-Verbund.

BACKGROUND: The concurrent presence or manifestation of multiple chronic conditions, i.e. multimorbidity, poses a challenge to affected patients and their relatives, physicians, and practitioners, and to the health care system in general. Aiming to improve medical care for different chronic diseases, the Chronic Care Model also appears to be suited for multimorbidity. The established research consortium PRISCUS is trying to create some of the prerequisites for a new care model for multimorbid, elderly patients oriented along the lines of the Chronic Care Model. METHODS AND RESULTS: Four out of seven subprojects of the research consortium provide an overview of some of their findings. Topics in a sports medicine subproject were the assessment of physical activity by means of a newly developed questionnaire and the development and feasibility testing of an exercise program for elderly people with chronic conditions and mobility impairment. Partners from family medicine implemented geriatric assessment in a primary care setting and evaluated its consequences. In a pharmacological subproject, potentially inappropriate medication as well as drug-drug interactions and dosing errors were addressed. The health economic subproject investigated quality of life impairment due to multiple chronic diseases and the effects of multimorbidity on costs. CONCLUSIONS: The results of the PRISCUS research consortium allow a better description of consequences of multimorbidity and illustrate at least some new approaches towards prevention, diagnosis, and treatment of patients suffering from multimorbidity. Ongoing projects will test the efficacy of a physical activity program and a new complex intervention to reduce potentially inappropriate medication in the elderly. With this, the research consortium will create some prerequisites for a new health care model for patients with multimorbidity comparable to the Chronic Care Model.

[Reliability of the PRISCUS-PAQ. Questionnaire to assess physical activity of persons aged 70 years and older]. / Reliabilität des PRISCUS-PAQ. Fragebogen zur Erfassung körperlicher Aktivität von Personen im Alter von 70 Jahren und älter.

A questionnaire (Q) to measure physical activity (PA) of persons ≥70 years for epidemiological research is lacking. The aim was to develop the PRISCUS-PAQ and test the reliability in community-dwelling people (≥70 years). Validated PA questionnaires were translated and adapted to design the PRISCUS-PAQ. Its test-retest reliability for 91 randomly selected people (36% men) aged 70-98 (76±5) years ranged from 0.47 (walking) to 0.82 (riding a bicycle). The overall activity score was 0.59 as determined by the intraclass correlation coefficient (ICC). Recording of general activities, e.g., housework (ICC=0.59), was in general less reliable than athletic activities, e.g., gymnastics (ICC=0.76). The PRISCUS-PAQ, which is a short instrument with acceptable reliability to collect the physical activity of the elderly in a telephone interview, will be used to collect data in a large cohort of older people in the German research consortium PRISCUS.
