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 Adults

Prepared by R. Wayne Elford, MD, CCFP, FCFP, Professor, University of Calgary, Alberta



Objective
To make recommendations regarding the prevention of unintentional household and recreational injuries (particularly drownings, suffocation, bicycle/sports-related injuries and firearms) in adults in Canada.

Burden of Suffering
Approximately 9,000 Canadians die annually of unintentional injuries, about 5% of all deaths. The leading causes of death from household and recreational injuries include falls (21%), drownings (6.4%), burns and fire-related injuries (4.8%), suffocation (4.7%), poisonings (4.7%), bicycle/sports-related deaths (1.7%), and firearms (0.7%). As many of these injuries occur in the younger age groups the societal burden due to loss of productive years from prolonged dependency due to disabilities, and due to acute care (7.9% of all hospital days), is considerable. In 1989 injuries were the second highest cause of potential years of life lost (PYLL) before 65 years of age in Canada.

Options
Preventive approaches were classified as individual patient counselling, legislative/environmental (physician discussions with legislators) and public health education (physician leadership of programs) (p529).

Outcomes
Injury-related deaths, injury rates, risk of head and brain injury (p530-31).

Evidence
MEDLINE was searched from 1981 to November 1992 using the major MeSH heading ‘accidents’ under the subheadings diagnosis, economics, epidemiology, law and jurisprudence, mortality, prevention and control, standards and trends; and not aviation, occupational or traffic accidents. Other sources were Statistics Canada, Health and Welfare Canada and the Insurance Bureau of Canada. Study results were synthesized in table or graphic format only.

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 1991 to June 1993. Consensus was reached on final recommendations.

Benefits, Harms, and Costs
Little or no evidence exists regarding the effect of physician counselling on substance abuse behaviour during water sports, or safe storage of firearms. An RCT reported that an educational program had no effect on helmet use among school-aged children (p530).

Evidence from a case-control study suggests that abstaining from alcohol use during water sports reduces drowning rates among young adults (p532).

A case-control study found that among bicycle riders involved in crashes, helmet use reduced risk of head injury by 85% (OR 0.15, 95% CI 0.07 to 0.29) and of brain injury by 88% (OR 0.12, 95% CI 0.04 to 0.40). These results may be confounded by other characteristics associated with riders who wear helmets (p530).

Expert opinion Some Level III (level III evidence) suggests that safe storage of guns may reduce unintentional deaths among children.

A review of before and after studies of programs teaching the Heimlich maneuver suggests a possible reduction in choking deaths of 10% to 45% (p530).

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. The Year 2000 Injury Control Objectives for Canada include individual counselling targeted at high-risk groups. The American Academy of Pediatrics recommendations on bicycle helmet use include physician counselling, product availability and standards, community-based programs to promote use and presentation of helmet-wearing role models in the popular media. In 1989, the U.S. Preventive Services Task Force recommended counselling about alcohol or drug use during potentially dangerous activities, and other measures to reduce risk of unintentional injury (p531).

Sponsors
The Canadian Task Force on Preventive Health Care developed this guideline with funding from Health Canada.
