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.

Trunk sway in mildly disabled multiple sclerosis patients with and without balance impairment

Multiple sclerosis (MS) causes a broad range of neurological symptoms. Most common is poor balance control. However, knowledge of deficient balance control in mildly affected MS patients who are complaining of balance impairment but have normal clinical balance tests (CBT) is limited. This knowledge might provide insights into the normal and pathophysiological mechanisms underlying stance and gait. We analysed differences in trunk sway between mildly disabled MS patients with and without subjective balance impairment (SBI), all with normal CBT. The sway was measured for a battery of stance and gait balance tests (static and dynamic posturography) and compared to that of age- and sex-matched healthy subjects. Eight of 21 patients (38%) with an Expanded Disability Status Scale of 1.0-3.0 complained of SBI during daily activities. For standing on both legs with eyes closed on a normal and on a foam surface, patients in the no SBI group showed significant differences in the range of trunk roll (lateral) sway angle and velocity, compared to normal persons. Patients in the SBI group had significantly greater lateral sway than the no SBI group, and sway was also greater than normal in the pitch (anterior-posterior) direction. Sway for one-legged stance on foam was also greater in the SBI group compared to the no SBI and normal groups. We found a specific laterally directed impairment of balance in all patients, consistent with a deficit in proprioceptive processing, which was greater in the SBI group than in the no SBI group. This finding most likely explains the subjective symptoms of imbalance in patients with MS with normal CBT.

Health care for older persons in Switzerland: a country profile

Switzerland has the second-most-expensive healthcare system worldwide, with 11.5% of gross domestic product spent on health care in 2003. Switzerland has a healthcare system with universal insurance coverage and a social insurance system, ensuring an adequate financial situation for 96% of the 1.1 million older inhabitants. Key concerns related to the care of older persons are topics such as increasing healthcare costs, growing public awareness of patient autonomy, and challenges related to assisted suicide. In 2004, the Swiss Academy of Medical Sciences issued guidelines for the care of disabled older persons. Since 2000, geriatrics has been a board-certified discipline with a 3-year training program in addition to 5 years of training in internal or family medicine. There are approximately 125 certified geriatricians in Switzerland, working primarily in geriatric centers in urban areas. Switzerland has an excellent research environment, ranking second of all countries worldwide in life sciences research-but only 13th in aging research. This is in part due to a lack of specific training programs promoting research on aging and inadequate funding. In addition, there is a shortage of academic geriatricians in Switzerland, in part due to the fact that two of five Swiss universities had no academic geriatric departments in 2005. With more-adequate financial resources for academic geriatrics, Switzerland would have the opportunity to contribute more to aging research internationally and to improved care for older patients.

The PRO-AGE study: an international randomised controlled study of health risk appraisal for older persons based in general practice

BACKGROUND: This paper describes the study protocol, the recruitment, and base-line data for evaluating the success of randomisation of the PRO-AGE (PRevention in Older people-Assessment in GEneralists' practices) project. METHODS/DESIGN: A group of general practitioners (GPs) in London (U.K.), Hamburg (Germany) and Solothurn (Switzerland) were trained in risk identification, health promotion, and prevention in older people. Their non-disabled older patients were invited to participate in a randomised controlled study. Participants allocated to the intervention group were offered the Health Risk Appraisal for Older Persons (HRA-O) instrument with a site-specific method for reinforcement (London: physician reminders in electronic medical record; Hamburg: one group session or two preventive home visits; Solothurn: six-monthly preventive home visits over a two-year period). Participants allocated to the control group received usual care. At each site, an additional group of GPs did not receive the training, and their eligible patients were invited to participate in a concurrent comparison group. Primary outcomes are self-reported health behaviour and preventative care use at one-year follow-up. In Solothurn, an additional follow-up was conducted at two years. The number of older persons agreeing to participate (% of eligible persons) in the randomised controlled study was 2503 (66.0%) in London, 2580 (53.6%) in Hamburg, and 2284 (67.5%) in Solothurn. Base-line findings confirm that randomisation of participants was successful, with comparable characteristics between intervention and control groups. The number of persons (% of eligible) enrolled in the concurrent comparison group was 636 (48.8%) in London, 746 (35.7%) in Hamburg, and 1171 (63.0%) in Solothurn. DISCUSSION: PRO-AGE is the first large-scale randomised controlled trial of health risk appraisal for older people in Europe. Its results will inform about the effects of implementing HRA-O with different methods of reinforcement.
