Studies have suggested that occupational disease and injury are under-recog
nized by clinicians. To estimate the frequency of occupational factors in d
isease and injury, 108 patients in a general (not occupational) health care
facility were interviewed about the frequency and types of workplace-healt
h interactions. Thirty-nine percent reported possible causation by work, an
d 66% reported a possible increase in symptoms by work, even if not caused
by work. Twenty-seven percent reported changing jobs and/or tasks because o
f work-health interactions. The majority of men and women reported that wor
ksite changes could improve their functional ability at work. This study: t
herefore indicates that (1) occupational health concerns are common in prim
ary care clinics, even if not addressed by clinicians; (2) the definition o
f occupational health concerns should be broadened to include disease cause
d by work, disease symptoms worsened by work, and the need for occupational
accommodation even if the disease itself is not caused by work; and (3) in
quiring about patient concerns about workplace-health interactions can prov
ide clinicians with significant opportunities for primary, secondary, and t
ertiary prevention.
