Traditionally, inadequate training has been considered the major barrier to
recognition of occupational disease. A survey of 136 practitioners was con
ducted to determine which barriers were actually considered most relevant.
The sample included three subgroups: primary care, occupational medicine-or
iented, and Mexican. Four aggregate indices were derived: Knowledge, Time,
Unpleasant aspects, and Importance. Inadequate Time was as important as ina
dequate Knowledge, whereas perceived lack of Importance and Unpleasant aspe
cts were less relevant. Patterns among the subgroups were generally compara
ble. This study implies that training more occupational medicine specialist
s in increasing recognition is not sufficient unless specific strategies to
overcome time constraints are also implemented. For example, emphasizing a
"complete occupational history" may be counterproductive. Limiting histori
es to selected patients; use of focused, brief histories; and, perhaps, com
puter-based methods are needed.
