Management of bias and conflict of interest among occupational exposure limit expert groups

• Our aim was to evaluate policies and procedures for management of conflict of interest (CoI) and other sources of bias, implemented in Occupational Exposure Limit (OEL) expert groups. First, we compiled procedural criteria applicable to OEL-setting, based on literature on CoI and systematic reviews. Second, we identified 58 global OEL-sources and sought the underlying expert groups and operating procedures. We identified eleven active groups, of which five have documented CoI policies. In all five, CoI management is based on declarations of interests (DoIs) and removal of experts from decisions in which they have an interest. Notable differences include publication of DoIs (three of five groups), limitation of DoI to current interests (two groups), quantitative limits for financial interests (none specified to ≥€10,000 per interest), control procedures for undisclosed CoI (one group), and procedures in case of discovery of undisclosed CoI (three groups). Methods to evaluate study quality are described by three groups, while reproducible and comprehensive strategies to identify and select data receive less attention. We conclude that procedures to manage CoI and bias are not broadly implemented, or at least not openly and transparently communicated. This lack of visible procedures is remarkable, considering OEL's impact on health and economy.
