The efficacy of educational programming to reduce musculoskeletal work injury is poorly defined in the literature. This study investigated current programming offered by ten nationally based companies to determine evaluation methods, the parameters being measured, and measurement frequency. Using a telephone survey approach, researchers used open-ended questions to collect descriptive data from the respondents. Information was collated and categorized into four parameter groupings: descriptive, surveillance, educational program mechanics, and work practices and behavior. The parameters measured and the methods of data collection varied for each company surveyed. Overall, there was a profound lack of comparison of parameters measured over time. In particular, behavior, which has been identified as the key to continuous injury prevention, was not evaluated over time by any of the respondents. Even if current programming has incorporated good prevention strategies, their efficacy cannot be demonstrated without more clearly defined parameters and methods of data collection and analysis....
