Injury caused by lifting: a study of the nurse's viewpoint.

The predictive accident ratio models of Heinrich ( 1931 ), Bird and Germain ( 1966 ), Fletcher and Douglas ( 1971 ) and Tye ( 1976 ) demonstrated a consistent relationship between untoward events, injury and injury severity. This implies that accidents are not necessarily without apparent cause, but predictable and so preventable occurrences. There could therefore be factors in the nurse's working environment which consistently put the nurse at risk of injury.
