Please note: In 2003, the CTF updated its Grades of Recommendations to include an "I Recommendation" for situations where insufficient evidence exists to allow a recommendation to be made.  (Formerly, these situations were captured under a "C Recommendation".)  This change is not retroactive, and all "C Recommendations" made prior to 2003 have not been reevaluated in light of the new "I" recommendation grade.  For a discussion of these recommendation grades, please link to the 2003 article in the Canadian Medical Association Journal here.

Prevention of Household and Recreational Injuries in the Elderly

Prepared by R. Wayne Elford, MD, CCFP, FCFP, Professor and Director of Research and Faculty Development, Department of Family Medicine, University of Calgary, Alberta



Objective
To make recommendations about the prevention of unintentional household and recreational injuries (particularly falls and burns) among elderly persons in Canada. This updates a 1979 report.

Burden of Suffering
Injuries sustained in falls are a major cause of mortality and morbidity in the elderly population. In 1988 there were 2,100 deaths due to falls. Falls resulting in serious injury or death were much more frequent among those aged 55 and over; 70% of fatal falls were among persons 75 years and older. One percent of falls by individuals aged 65 and older result in hip fracture. Fallers tend to be more physically and functionally impaired with hip weakness, have poor balance and more medications predictive of falls. Risk factors for falling include increased age, female sex, presence of more than one disease, dementia, depression, acute illness, decreased morbidity, confinement to the home, postural gait instability, gait disturbance, sensory impairment, medications and possible dietary deficiencies.

Other causes of unintentional death among Canadian adults over age 65 include drowning (12 % of 429 drowning deaths in 1987), burns, scalds and fire-related accidents (21% of 402 fire-related deaths in 1988), poisoning (16% of 424 poisoning deaths in 1987), and suffocation (13% of 415 suffocation deaths 1987).

Options
Public health education, legislation and environmental modification, individual counselling. Multidisciplinary post-fall assessment and monitoring of patients for medical impairment.

Outcomes
Outcomes included falls and fall-related mortality, hospitalizations and hospital days (p915). Incidence and severity of fire and burn injuries were also considered.

Evidence
MEDLINE was searched for the years 1981 to November 1991 using the major MeSH heading "accidents" with subheadings "diagnosis", "economics", "epidemiology", "law and jurisprudence", "mortality", "prevention and control", "standards and trends" and not "aviation, occupational or traffic accidents". Other data sources included Statistics Canada, Health and Welfare Canada, the Insurance Bureau of Canada, the Poison Control Centre, supporting documents from other recommending bodies and citations from identified references.

Values
The 13-member Task Force of experts in family medicine, geriatric medicine, pediatrics, psychiatry and epidemiology used an evidence-based method for evaluating the effectiveness of preventive health care interventions. Recommendations were not based on cost-effectiveness of options. Patient preferences were not discussed.

Background papers providing critical appraisal of the evidence and tentative recommendations prepared by the chapter author were pre-circulated to the members. Evidence for this topic was presented and deliberated upon in 1- to 2-day meetings, 2 to 3 times per year from January 1993 to June 1993. Consensus was reached on final recommendations.

Benefits, Harms, and Costs
A 1989 review found no controlled trials on examining the effectiveness for reducing falls of detecting disease, counselling about or changing medications, promoting exercise, home visits to assess environmental hazards, educating patients, physical therapy, and balance and gait training on reducing falls.

An RCT evaluated the effectiveness of care given in a ‘Falls Clinic’ which provided coordinated care by a geriatrician, neurologist, cardiologist and psychiatrist with resources in audiology, ophthalmology and podiatry and home visits by occupational therapists. For 1 year, there were no falls in 77% of patients. An RCT of post-fall assessment including physical examination and environmental assessment by a nurse practitioner, laboratory tests and 24-hour Holter monitoring reduced hospitalizations by 26% (p<0.05) and hospital days by 52% (p<0.01), but did not significantly reduce falls (9% reduction) or mortality (17% reduction) during 2 years of follow-up.

Evidence on individual counselling or public education about the use of safety aids and the use of non-flammable fabrics and self-extinguishing cigarettes is limited to expert opinion.

Recommendations
Recommendation grade [A, B, C, D, E]  and level of evidence [I, II-1, II-2, II-3, III] are indicated after each recommendation. Citations in support of individual recommendations are identified in the guideline text.

Validation
This report was externally peer-reviewed. Recommendations and background papers were sent for external peer review. The 1989 U.S. Preventive Services Task Force suggested that it would be prudent to provide counselling on injury prevention measures. The National Institute on Aging provides recommendations for primary care physicians based on expert opinion regarding routine assessment for falls and appropriate interventions.
