Occupational screenings: Recruitment from private industry

Occupational screening involving private sector employees represents a source with relatively high volumes of initial contacts and entries, a low ratio of entries to initial contacts, and a relatively high effort level requirement for the recruitment team. In the CPPT, all centers used this strategy, to provide overall, 26% of initial contacts, 20% of first protocol visits and 17% of entries. Occupational screening is costly and involves careful planning and implementation of complex arrangements. Procedures for contacting industries and conducting screenings are described. Screening yield was inversely related to company size.
