What Is
Distilling and Indexing Scientific Information?
Figure
11. Mapping (distilling and indexing) is an important step in the surveillance
cycle.
To support
sound decisions, the facts must be distilled from the vast sea of data in the
scientific literature, much of it irrelevant for the particular questions at
hand. The information in Haz-Map was comprehensively collected and indexed by a
content expert (a physician board certified in occupational medicine). Collecting
the facts and placing them in context is one part of the surveillance cycle that
promotes collaboration between public health professionals and frontline
doctors.
Distilling
refers to the process of sifting through the information for inclusion or
exclusion. Only the most useful information is included. For example, the
information in the exposure assessment section was selected to help the
clinician estimate the dose received by the exposed worker. What are the
recommended exposure limits for this chemical? What is the vapor pressure, odor
threshold, half-life, and biological exposure index (BEI)?
