Journal of Occupational Medicine and Toxicology 2011 6 11 http content 6 1 11 _ JOURNAL OF OCCUPATIONAL MEDICINE AND TOXICOLOGY STUDY PROTOCOL Open Access Enterprise size and risk of hospital treated injuries among manual construction workers in Denmark a study protocol Betina H Pedersen1 Harald Hannerz1 Ulla Christensen2 and Finn Tuchsen1 Abstract Background In most countries throughout the world the construction industry continues to account for a disturbingly high proportion of fatal and nonfatal injuries. Research has shown that large enterprises seem to be most actively working for a safe working environment when compared to small and medium-sized enterprises. Also statistics from Canada Italy and South Korea suggest that the risk of injury among construction workers decreases with enterprise size that is the smaller the enterprise the greater the risk of injury. This trend however is neither confirmed by the official statistics from Eurostat valid for EU-15 Norway nor by a separate Danish study -although these findings might have missed a trend due to severe underreporting. In addition none of the above mentioned studies controlled for the occupational distribution within the enterprises. A part of the declining injury rates observed in Canada Italy and South Korea therefore might be explained by an increasing proportion of white-collar employees in large enterprises. Objective To investigate the relation between enterprise size and injury rates in the Danish construction industry. Methods Design All male construction workers in Denmark aged 20-59 years will be followed yearly through national registers from 1999 to 2006 for first hospital treated injury ICD-10 S00-T98 and linked to data about employment status occupation and enterprise size. Enterprise size-classes are based on the Danish business pattern where micro less than 5 employees small 5-9 employees and medium-sized 10-19 employees enterprises will be compared to .
