Stay@Work: Participatory Ergonomics to prevent low back and neck pain among workers: design of a randomised controlled trial to evaluate the (cost-)effectiveness
Background Low back pain ( LBP ) and neck pain ( NP ) are a major public health problem with considerable costs for individuals , companies and society . Therefore , prevention is imperative . The Stay@Work study investigates the (cost-)effectiveness of Participatory Ergonomics ( PE ) to prevent LBP and NP among workers . Methods In a r and omised controlled trial ( RCT ) , a total of 5,759 workers working at 36 departments of four companies is expected to participate in the study at baseline . The departments consisting of about 150 workers are pre-stratified and r and omised . The control departments receive usual practice and the intervention departments receive PE . Within each intervention department a working group is formed including eight workers , a representative of the management , and an occupational health and safety coordinator . During a one day meeting , the working group follows the steps of PE in which the most important risk factors for LBP and NP , and the most adequate ergonomic measures are identified on the basis of group consensus . The implementation of ergonomic measures at the department is performed by the working group . To improve the implementation process , so-called ' ergocoaches ' are trained . The primary outcome measure is an episode of LBP and NP . Secondary outcome measures are actual use of ergonomic measures , physical workload , psychosocial workload , intensity of pain , general health status , sick leave , and work productivity . The cost-effectiveness analysis is performed from the societal and company perspective . Outcome measures are assessed using question naires at baseline and after 6 and 12 months . Data on the primary outcome as well as on intensity of pain , sick leave , work productivity , and health care costs are collected every 3 months . Discussion Prevention of LBP and NP is beneficial for workers , employers , and society . If the intervention is proven (cost-)effective , the intervention can have a major impact on LBP and NP prevention and , thereby , on work disability prevention . Results are expected in 2010.Trial registration IS RCT
