Title: Developing and Evaluating Interventions Using Surveillance Data
Author: Kucera, KL; Marshall, SW
Abstract: Epidemiological studies and surveillance systems are described, their temporal scales defined and the impact of randomization factors discussed. A nonexhaustive listing of examples of surveillance systems data sources for fatal and nonfatal injuries are provided, such as the National Collegiate Athletic Association’s (NCAA) Injury Surveillance System (ISS). The case-crossover design has been used to study the transient effects of intermittent exposures on rare acute events and defines case times (the period immediately before the onset of event) and control times (the previous dives of the subjects) within the same individual. In the context of scuba diving, the cases and controls are dives, not divers. Advantages of the case-crossover design are that subjects serve as their own controls and are self-matched on individual-level confounders, and there is no need to recruit control subjects because subjects provide both case times and control times. High-quality surveillance data is important for monitoring trends and informing interventions. Analytic epidemiological studies such as pre/postdesign or case-crossover design can be “spun off” surveillance systems.
