Fall is a major problem in the elderly. One in three persons aged 65 years or more falls at least once a year, and falls are associated with increased mortality, morbidity, disability and loss of independence and thus have substantial socio-economic consequences . As the proportion of elderly in the population is increasing, it is important to prevent falls to limit the associated burden and healthcare demand associated with falls.
The reasons for falling are varied. Some falls are accidental and occur even in old people without any balance problems. However, most falls in the elderly are caused by diseases that affect the ability to control balance or they are due to disturbances in heart rhythm or blood pressure. Thus, recurrent falls have a disease-related aetiology. Geriatric fall prevention based on comprehensive geriatric assessment supplemented with evaluation of underlying internal risk factors for falling followed by interventions targeting identified modifiable risk factors have proved effective in reducing the risk of falling in many studies [2, 3]. The participants in these studies have been cognitively intact. Geriatric fall prevention in elderly with dementia has not been shown to reduce the risk of falls . Patients with severe dementia, patients with abuse of alcohol or medicine and weakened elderly people with terminal disease need other supportive actions [5, 6].
It is well documented that falls may be prevented . Most interventions require a physical effort of the patient, e. g. strength or balance exercises, and require sufficient cognitive resources to understand or follow fall preventive advice. Therefore, the interventions that have proven effective in elderly living in the community are different from the interventions that are effective in frail nursing home residents . Frail elderly people with severe medical or cognitive diseases need more indirect and supportive interventions. Several studies have shown an effect of intervention programmes comprising staff education, environmental adaptions and mild exercises, including exercises linked to functional lifestyle tasks such as safe transfer, which normally takes place in the context of home care service [9, 10].
To identify elderly at risk of falling, the Danish Health and Medicines Authority (DHMA) recommends systematic screening of 65+-year-old fallers visiting the emergency department. According to these recommendations, an elderly faller should be offered fall assessment if he/she answers “yes” to one or more of four questions about gait or balance problems, further falls within the past year, dizziness or possible syncope . This assessment can be performed at a hospital, e.g. in a geriatric fall and syncope clinic, or in primary healthcare, e.g. by the patient’s general practitioner (GP) or by home care nurses. Guidelines  are in place on geriatric fall assessment, and guidelines on fall prevention are currently being introduced in home care .
The effectiveness in reducing the risk of falling depends on uptake and adherence. Refusal to participate in fall prevention programmes, dropouts and low adherence to exercise or recommendations have frequently been reported . There are various reasons for this, e.g. denial of falling risk and practical or psychological barriers .
We have previously described the result of screening for fall risk performed in four settings where health staff meets elderly fallers; emergency department for outpatients (ED-out), emergency department for inpatients, home care service (HCS) and preventive home visits. The screening was carried out according to the recommendation from the DHMA in order to identify elderly at risk of falling. Of 2016 persons aged 65+ years who were screened, 1,276 needed fall preventive actions. Of these, 811 met the study criteria. Inversely, 465 with dementia, abuse or terminal diseases needed other supportive actions offered by caregivers in primary healthcare.
The purpose of this study was to describe the rate of participation, the dropout rate and the prevalence of simple markers for physical and cognitive performance in dropouts and completers of the intervention.
The screening and the results are described in detail elsewhere . The screening was performed in the four settings using a structured questionnaire with information about general health and co-morbidity. If necessary, survey answers were supplemented with information from available records. If the patient was at risk of falling, (s)he was offered referral to a fall and syncope clinic. The exclusion criteria were dementia, abuse, terminaldisease or living in a nursing home. It was noted whether the patient accepted referral or refused the offer and the reason why. All who accepted referral were given an appointment in the clinic. Those who did not turn up for the examination were contacted to establish the cause of their non-attendance and to offer a new appointment.
In total, the study population consisted of 987 elderly persons; 811 elderly identified by screening and 176 elderly referred to the fall clinic by GPs or hospital doctors. Patients were assessed by a doctor, a nurse and a physiotherapist. The examination programme consisted of a thorough geriatric fall assessment including assessment of vision, somatosensoric and vestibular function, neurological and medical assessment, electrocardiography and laboratory screening and if necessary further investigations, e. g. event recording or tilt table, were planned. Physical, cognitive and self-care resources were evaluated by the 30-second chair stand test, Timed Up and Go, number of co-morbidities, Mini Mental State Examination, body mass index, the five-item geriatrics depression scale and by number of home care services.
Based on the findings, appropriate interventions were initiated. In addition to medical or other relevant treatment, the participants took part in exercise classes supervised by physiotherapists. Exercise classes were implemented in combination with an individualised home exercise programme. It was noted if the whole programme (assessment and intervention) was completed, and any reasons why this was not the case were noted when applicable. In case patients were discharged before completion of the planned intervention services, primary healthcare was contacted to remedy the patient’s problems. The study was conducted in the period from October 2006 to October 2009.

Acceptance and refusal of referral to assessment in the fall clinic
Of the 811 elderly who needed fall assessment, 342 (42%) accepted the offer (Figure 1). There were large differences in the degree of acceptance among elderly from each of the various screening settings. While 76% of the elderly fallers identified in ED-Out accepted, only 41% and 19% in the PVH and HCS, respectively, did (p < 0.0001). The mean refusal rate was 47%. Acceptance was highest in the HCS population (66%) and lowest in ED (14%). The most frequent reason for refusal was that the elderly persons felt that the referral was irrelevant, and almost one third stated that they did not have the energy to undergo examinations. Persons accepting referral were younger (mean 82.6 years) than persons who refused (mean 85.4 years) (p < 0.000)
Attendance to the fall clinic after referral
A total of 518 fallers were referred to the fall clinic, including 342 from the four settings and 176 from GPs and hospital departments. Only 402 (78%) attended the clinic, ranging from 92% of elderly referred from GPs to 49% from ED-Ward (p < 0.0001). The reasons for early dropout appear from Table 1. A total of 47 (40%) were not interested despite acceptance, 26 (22%) felt too exhausted and 31 (27%) had been referred to another entity in the meantime. Persons who attended the fall clinic were younger (81.2 years) than dropouts (83.9 years), p < 0.000.
Completion of the programme
In all, 113 of the 402 who attended the fall clinic did not complete the programme, including 65 patients who dropped out by their own request either because they did not want to proceed or because they felt too exhausted (Table 1). Another 62 patients were unable to participate in the exercise programme due to physical problems or problems understanding and complying with instructions, and they were referred to a more suitable intervention/care. Patients completing the programme were younger (80.5 years) than dropouts and those who were discharged from the exercise programme. The oldest group was the one with patients who dropped out because they felt too exhausted (83.7 years), p < 0.000.
Patients referred from GPs (66%) and ED-out (62%) had the highest level of completion, whereas more than half of those referred from HCS dropped out, died, became seriously ill or moved (p < 0.031). Of the 811 who were offered referral to the fall clinic after screening, only 137 (17%) completed the programme. From HCS, only 3% completed.
Differences in indicators of physical, cognitive and self-care resources between those who completed the entire programme and various groups that did not.
There was no difference between the groups with regard to the number of co-morbidities and signs of depression. Significant factors are shown in Table 2. Patients who dropped out differed on all items from those who completed the programme by being physically and cognitively weaker and by needing more help. There were no differences between the dropout groups except that underweight occurred more frequently among those who dropped out because they felt too exhausted. The indicators were unevenly distributed in the different referring entities, and logistic regression showed that the cognitive and physical indicators were of significant importance, while the referring entity and age had no impact (Table 3).
The present study describes the level of acceptance and implementation of a geriatric fall assessment and intervention programme for older people identified as being in need of fall prevention either by screening for fall risk in different settings or because they were referred by GPs or hospital doctors.
The study shows large differences in the rate of acceptance of patients from different referring units. The rate of acceptance was lowest in HCS, which includes many frail patients with a low level of self-care. Also, the rate of early dropout and frail elderly who could not comply was highest in the HCS and ED-out. The participation rate was low as only 50% of the invited elderly accepted. Because only 36% were included, we only have detailed knowledge of less than one third of those who were at risk of falling according to the screening.
In many studies in which elderly have been offered hospital-based fall assessment, the rate of participation has been low, under 50% [2, 3, 17]. The exclusion criteria were largely the same as in the present study, and the exclusion rates were also comparable to ours. In one study, 82% accepted an offer of a home visit from a municipal fall consultant after screening in the ED, but this study had no exclusion criteria and the participants had a high occurrence of frailty indicators . A possible explanation for the higher rate of acceptance in our group of frail elderly may be that it is easier for this group to accept a home visit. It is shown that practical problems such as transportation have an impact on participation and many prefer a home-based training program to group-based training [15, 17].
Although known barriers to attendance in frail patients were countered, e. g. by offering transport to both the patient and to family members, close to 30% did not complete the programme; 14% terminated because they could not find the energy, died or became ill; and another 15% were unable to finish focused training due to physical or cognitive reasons. There were large differences in completion rates among the various referring units, but a detailed analysis demonstrated that the dominant indicators for non-completion were physical or cognitive weakness. In relation to completion of training programmes, several studies have indicated that lack of physical energy has an impact and that the highest rates of completion were found in individuals who were more fit and more physically active at baseline .
Those who refused the offer of referral justified it with a lack of interest or energy, much in line with those who dropped out from the programme. As physical and cognitive impairment were indicators of dropout, it is possible that physical and cognitive weakening plays an important role in refusal of geriatric fall assessment. Patients referred from their GP have the lowest share of early dropout and the highest completion rate. This may be explained by the GP’s knowledge of their patients.
Screening for fall risk is quick and can ensure early implementation of relevant initiatives and thereby reduce the risk of new falls. Although recommended by the DHMA, screening is done only sporadically , and it is worrisome that admissions for elderly due to fractures have increased continuously over the past six years , an increase that exceeds what than can be expected from the increase in the number of elderly people.
This study shows that geriatric fall assessment in conjunction with screening for fall risk is not appropriate. Geriatric fall assessment is resource-consuming, it drains staff resources and entails high demands on patients, and is relevant only to a limited part of the fall population. Of 811 who were in need of fall assessment according to the survey, only 137 (17%) completed the geriatric programme. The main reason explaining dropout was cognitive or physical weakness. This study identifies a considerable need for fall prevention offers tailored to the large group of frail fall patients who have a low level of self-care. In conclusion, we need a systematic and differentiated fall prevention programme to cover the whole range of fallers.
