Variability in prescription drug utilization: issues for research.

The authors report the results of a literature review to identify research issues relating to physician prescribing practices and evaluate the potential for existing Canadian databases to support initiatives to improve prescribing practices. Methodologies such as small-area variation analysis and drug utilization reviews are discussed, and Canadian data sources relating to drug prescribing are assessed. The authors conclude that small-area variation analysis can be used to identify differences in drug utilization rates. A ranking method to identify drugs with the greatest variability in utilization can then be used to establish priorities for further analysis. After statistically significant factors associated with prescribing patterns are identified, intervention and policy formation will be possible. This will involve a more sophisticated integration of existing provincial information sources and the adoption of uniform guidelines to promote rational prescribing practices.

Injuries associated with in-line skating from the Canadian hospitals injury reporting and prevention program database.

In-line skating, also known as rollerblading, is an increasingly popular recreational activity that carries with it the potential for injury. As reported in the Canadian Hospitals Injury Reporting and Prevention Program database (CHIRPP), 194 children were injured while in-line skating. Fractures to the radius and ulna were the most common type of injury sustained (57.5%), followed by lacerations and abrasions (14.9%). Five children had concussions and very few children reported wearing protective gear such as a helmet or wrist, elbow and knee protectors. Compared to the database overall, in-line skaters suffered more severe injuries and were more likely to require follow-up treatment. Safety implications in relation to protective gear and learning the sport of in-line skating are discussed.
