Lost productive time and cost due to common pain conditions in the US workforce.
CONTEXT Common pain conditions appear to have an adverse effect on work , but no comprehensive estimates exist on the amount of productive time lost in the US workforce due to pain . OBJECTIVE To measure lost productive time ( absence and reduced performance due to common pain conditions ) during a 2-week period . DESIGN AND SETTING Cross-sectional study using survey data from the American Productivity Audit ( a telephone survey that uses the Work and Health Interview ) of working adults between August 1 , 2001 , and July 30 , 2002 . PARTICIPANTS R and om sample of 28 902 working adults in the United States . MAIN OUTCOME MEASURES Lost productive time due to common pain conditions ( arthritis , back , headache , and other musculoskeletal ) expressed in hours per worker per week and calculated in US dollars . RESULTS Thirteen percent of the total workforce experienced a loss in productive time during a 2-week period due to a common pain condition . Headache was the most common ( 5.4 % ) pain condition result ing in lost productive time . It was followed by back pain ( 3.2 % ) , arthritis pain ( 2.0 % ) , and other musculoskeletal pain ( 2.0 % ) . Workers who experienced lost productive time from a pain condition lost a mean ( SE ) of 4.6 ( 0.09 ) h/wk . Workers who had a headache had a mean ( SE ) loss in productive time of 3.5 ( 0.1 ) h/wk . Workers who reported arthritis or back pain had mean ( SE ) lost productive times of 5.2 ( 0.25 ) h/wk . Other common pain conditions result ed in a mean ( SE ) loss in productive time of 5.5 ( 0.22 ) h/wk . Lost productive time from common pain conditions among active workers costs an estimated 61.2 billion dollars per year . The majority ( 76.6 % ) of the lost productive time was explained by reduced performance while at work and not work absence . CONCLUSIONS Pain is an inordinately common and disabling condition in the US workforce . Most of the pain-related lost productive time occurs while employees are at work and is in the form of reduced performance
