Undetected falls among older adults attending medical clinics in four tertiary care centres in Sri Lanka; the need of a comprehensive geriatric assessment.

OBJECTIVE

Falls take a high priority among the prevalent medical conditions in old age. Despite this, a history of falls or the risk of future falls is not routinely assessed or properly managed in medical clinics in Sri Lanka. This study was done to evaluate the prevalence and factors associated with falls and recurrent falls among older adults attending medical clinics in four selected tertiary care centres in the country.

METHODS

A cross-sectional study was carried out at four centres (Teaching Hospital Karapitiya, Colombo South Teaching Hospital, Colombo North Teaching Hospital and University Hospital-Kotelawala Defence University) with 704 older adults, aged 65 years and above, attending medical clinics for more than six consecutive months. Information related to falls and possible associated factors (socio-demographic, behavioural, environmental and biological) were collected using an interviewer-administered questionnaire.

RESULTS

The Mean (SD) age of the participants was 72.5(5.5) years and 58.7% were females. Of the 704 total sample, 220 (31.3%, 95% CI 28-35%) participants experienced at least one fall after the age of 65, and 12.8% (95% CI 10-15%) (n = 90) experienced recurrent falls (two or more falls within the last 12 months). Falls were associated with gender, level of education, marital status, and physical dependence (p < 0.01). For those who had at least one fall, multiple logistic regression (MLR) revealed being single (p = 0.03, OR = 2.12, 95% CI; 1.052-4.304), being widowed/divorced/separated (p = 0.03, OR = 1.47, 95% CI; 1.039-2.093) compared to living with a spouse, presence of moderate (p = 0.007, OR = 1.72, 95% CI; 1.160-2.577) and severe (p = 0.001, OR = 2.98, 95% CI; 1.563-5.688) physical dependency compared to mild physical dependency as risk factors for falls. Having secondary education (p = 0.01, OR = 0.55, 0.350-0.876) was a protective factor for falls. For those with recurrent falls, MLR showed moderate physical dependency (p = 0.001, OR = 2.34, 95% CI; 1.442-3.821) compared to slight physical dependency as a risk factor.

CONCLUSIONS

Approximately one-third of the older adults attending medical clinics had experienced at least a single fall, and one-eighth have had recurrent falls, which were mostly unrecorded and not clinically assessed. Physical dependency was the major contributing factor to falls and recurrent falls. Falls assessment should be included in the routine clinical assessment of older adults attending outdoor medical clinics. Health professionals should be educated to detect and assess those at risk of falling and take appropriate measures to prevent or minimize falls.
