Prevalence and correlates of fear of falling, and associated avoidance of activity in the general population of community-living older people.

BACKGROUND: Little is known about the prevalence rates and correlates of fear of falling and avoidance of activity due to fear of falling in the general population of community-living older people. OBJECTIVE: To assess prevalence rates and study correlates of fear of falling and avoidance of activity due to fear of falling in this population. STUDY DESIGN AND SETTING: cross-sectional study in 4,031 community-living people aged > or =70 years. RESULTS: Fear of falling was reported by 54.3% and associated avoidance of activity by 379% of our population. Variables independently associated with fear of falling were: higher age (> or =80 years: odds ratio (OR) =1.79; 95% confidence interval (CI) =1.49-2.16), female gender (OR = 3.23; 95% CI = 2.76-3.79), poor perceived general health (OR = 6.93; 95% CI = 4.70-10.21) and multiple falls (OR = 5.72; 95% CI = 4.40-7.43). Higher age (> or =80 years: OR = 1.92; 95% CI = 1.59-2.32), poor perceived general health (OR = 11.91; 95% CI = 8.38-16.95) and multiple falls (OR = 4.64; 95% CI = 3.73-5.76) were also independently associated with avoidance of activity. CONCLUSIONS: Fear of falling and avoidance of activities due to fear of falling, were highly prevalent in our sample of community-living older people. Particularly, poor perceived general health showed a strong, independent association with both, fear of falling, and related avoidance of activity. Findings of our study may help health care professionals to identify people eligible for interventions aimed at reducing fear of falling and activity restriction.

A risk model for the prediction of recurrent falls in community-dwelling elderly: a prospective cohort study.

The object of this article was to determine the predictive value of risk factors for recurrent falls and the construction of a fall risk model as a contribution to a mobility assessment for the identification of community-dwelling elderly at risk for recurrent falling in general practice. The design was a prospective cohort study (n = 311). There were four primary health care centers. A sample stratified on previous falls, age, and gender of community-dwelling elderly persons aged 70 years or over (n = 311) was taken from the respondents to a mail questionnaire (n = 1660). They were visited at home to assess physical and mental health, balance and gait, mobility and strength. A 36-week follow-up with telephone calls every 6 weeks was conducted. Falls and fall injuries were measured. During follow-up 197 falls were reported by 33% of the participants: one fall by 17% and two or more falls by 16%. Injury due to a fall was reported by 45% of the fallers: 2% hip fractures, 4% other fractures, and 39% minor injuries. A fall risk model for the prediction of recurrent falls with an area under the curve (AUC) of 0.79, based on logistic regression analysis, showed that the main determinants for recurrent falls were: an abnormal postural sway (OR 3.9; 95% Cl 1.3-12.1), two or more falls in the previous year (OR 3.1; 95% Cl 1.5-6.7), low scores for hand grip strength (OR 3.1; 95% Cl 1.5-6.6), and a depressive state of mind (OR 2.2; 95% CI 1.1-4.5). To facilitate the use of the model for clinical practice, the model was converted to a "desk model" with three risk categories: low risk (0-1 predictor), moderate risk (two predictors), and high risk (> or =3 predictors). A fall risk model converted to a "desk model," consisting of the predictors postural sway, fall history, hand dynamometry, and depression, provides added value in the identification of community-dwelling elderly at risk for recurrent falling and facilitates the prediction of recurrent falls.

Falls in the elderly. II. Strategies for prevention.

In the companion paper, we have outlined how relevant risk factors for falls can be identified using a systematic approach. Once identified, the underlying diseases and pattern of (usually multiple) risk factors guides the design of an individually tailored intervention program. Such intervention programs follow one or more of the following goals: (a) to treat the underlying disease; (b) to reduce or even eliminate the number of falls; (c) to prevent or minimise the associated injuries; and (d) tertiary prevention of fall-related disability, including immobilisation, muscle weakness, reduced fitness, osteoporosis, fear of falling and mortality. The successful results of various intervention studies underscores that falls should be regarded as a potentially treatable disorder in elderly persons. Such knowledge is important for clinicians, which could apply prevention strategies to individual patients with risk factors that are strongly associated with falls. In addition, prevention is important for health policy makers who aim to reduce falls in the general population by reducing or eliminating commonly present risk factors (even if they are only weakly associated with falls).

The construction of a patient record-based risk model for recurrent falls among elderly people living in the community.

BACKGROUND: Predictive models of fall risk in the elderly living in the community may contribute to the identification of elderly at risk for recurrent falling. OBJECTIVES: Our aim was to investigate occurrence, determinants and health consequences of falls in a community-dwelling elderly population and the contribution of data from patient records to a risk model of recurrent falls. METHODS: A population survey was carried out using a postal questionnaire. The questionnaire on occurrence, determinants and health consequences of falls was sent to 2744 elderly persons of 70 years and over, registered in four general practices (n = 27 000). Data were analysed by bivariate techniques and logistic regression. RESULTS: A total of 1660 (60%) responded. Falls (> or =1 fall) in the previous year were reported by 44%: one-off falls by 25% and recurrent falls (> or =2 falls) by 19%. Women had significantly more falls than men. Major injury was reported by 8% of the fallers; minor injury by 49%. Treatment of injuries was by the GP in 67% of cases. From logistic regression, a risk model for recurrent falls, consisting of the risk factors female gender, age 80 years or over, presence of a chronic neurological disorder, use of antidepressants, problems of balance and sense organs and complaints of muscles and joints was developed. The model predicted recurrent falls with a sensitivity of 64%, a specificity of 71%, a positive predictive value of 42% and a negative predictive value of 86%. CONCLUSION: A risk model consisting of six variables usually known to the GP from the patient records may be a useful tool in the identification of elderly people living in the community at risk for recurrent falls.

Impact of gait problems and falls on functioning in independent living persons of 55 years and over: a community survey.

In a cross-sectional, population-based study among community-dwelling persons of 55 years and over the incidence of falls, risk indicators for falls, specifically age, and the impact of gait problems, falls and other risk factors on functioning was determined. A randomly age-stratified sample (n = 655) was taken from all independent living persons of 55 years and over (n = 2269) and registered in a primary health care centre. They received a mail questionnaire concerning demographic data, history of falls and injuries due to falls, physical and mental health status, gait problems, functional status, including social activities. The response rate was 62% (n = 405). Of the subjects aged 55 years and of those aged 65 years and over, 25% and 31% respectively fell at least once in the previous year. Half of the people reporting falls fell more than once. Serious injury occurred in 9% of the fallers, with 4% fractures. There is a significant association between falling and age and, even more clearly, between gait problems and age. The main risk factors of single and recurrent falls were female gender, physical health status and gait problems. Logistic regression analysis reveals that the main determinants of falling in general are gait problems and female gender and, of recurrent falling female gender, physical complaints and gait problems. Falls have some negative effect on functioning, i.e. mobility range and social activities, but this is overshadowed by mental status indicators and gait problems.

[Home visits by community health nurses can contribute to the family practitioner's knowledge of elderly patients]. / Huisbezoek door de wijkverpleegkundige kan bijdragen aan de kennis van de huisarts over oudere patiënten.

OBJECTIVE: To determine to what extent the general practitioner (GP) is aware of the health status and functioning of his elderly patients and in which areas this knowledge can be completed with the aid of community nurses. DESIGN: Cross-sectional, descriptive. SETTING: Department of General Practice. State University Limburg, Maastricht, the Netherlands. METHODS: A random sample of 59 patients aged 79 years and over, belonging to the population of a primary health care centre, were visited by community nurses. One patient was lost. The nurses inventoried the patients health complaints and their daily functioning by means of a structured questionnaire. Data from these home visits were compared with data from the same questionnaire, regarding the same patients, which the three GPs of the health centre had filled in on the basis of their medical records. RESULTS: Of the complaints recorded by the community nurses. 34% were not known to the general practitioners. This concerned mainly symptoms of depression, urinary incontinence, disabilities and handicaps of the musculoskeletal system. sleep disturbances, daily functioning and ability to cope. The main determinants of the ability to cope were impaired walking and to a lesser degree symptoms of depression. CONCLUSION: A structured interview of elderly patients by a community nurse yields substantial information about health problems.
