Evaluation of the white finger risk prediction model in ISO 5349 suggests need for prospective studies.
International Conference on Hand-Arm Vibration. Prague (CZE), 1995/05/09.
The risk prediction model for white fingers in Annex A of ISO 5349 is not likely to offer protection from all tools and all work processes.
It is also probable that some work place changes it has initiated are either redundant of lack the intended effect.
The main reasons for these shortcomings are the following.
The often demonstrated disagreement between predicted and observed white finger occurence may be related to the fact that the model is based on latency data.
This leads to an overestimation, to an unknown extent, of true group risks.
A possible healthy worker effect, resulting in underestimation, has not been considered, and uncertainty because of recall bias is connected with using latency as effect variale in a slowly developing disorder like white fingers.
The diagnostic criteria for white fingers have varied over the years, causing a possible inclusion of circulatory distrubances other than those induced by vibration.
Among insufficiently clarified matters induced by vibration.
Among insufficiently clarified matters unrelated to vibration are variations in individual susceptibility and other host factors that modify vibration effects, uncertainty concerning daily or total effective exposure, and the fact that variation in work methods and processes as well as ergonomic factors other than vibration tend to make different groups incomparable from the viewpoint of risk for injury.
