Important Key to Analyzing Confirming Industrial /Competing Causation
Factors, helping identify job modifications, Determining the correct
Group Number and level of functional loss for Permanent Disability.
Evidence Based Medicine / Assessment of Work-Relatedness
ACOEM Guidelines exist to improve the diagnostic process, the specificity
of each diagnostic test and the effectiveness of treatment in relieving
symptoms and achieving a cure. Industrial causation based on direct
trauma is very straightforward. A complaint requires analysis to
determine whether it is related to work, or the result of a combination
of factors- some that may be work related.
The first element in seeking an association between a work-related
health problem and a worksite factor is an accurate diagnosis. Evidence
based medicine also requires that the treater address: the complexity
of causation; work-related (vocational) factors, and personal (non-vocational)
factors - thus the great importance of providing the treating physician
with a proper Essential Functions Job Description and/or RU-91.
Treating physicians need to be very specific about the frequency,
intensity, duration or purported ergonomic factors that might be
associated with a specific case. Along with current California Code
of Regulation Guidelines, ACOEM Guidelines provide guidance for
(1) the formulation and clear communication of a worker’s
ability to stay at work and/or return to work, (2) estimating work
capacity functional loss and/or describing medical restrictions
and limitations. All of the above must be addressed to help prevent
delay-in-recovery and recurrences, as well as help distinguish chronic
pain from work related problems.
Causation Analysis / Supplemental Job Displacement Benefits.
Functional restoration, more than any other area, requires a good
understanding of the physical demands of the current occupation’s
essential functions and activities from both treating and evaluating
physicians.
Vocational Rehab Benefits under L.C.S. § 139.2 have been repealed.
The injured worker no longer has to be classified as “QIW”
to be entitled to new Supplemental Job Displacement Benefits. The
need for job modifications and offers of alternative work accommodations
require that the treating physician be provided with evidence-based
job analysis/description addressing the essential functions &
activities of the job. Whatever the basis of work capacity functional
loss, job modifications or restrictions, it is necessary for physicians
to state their sources of information.
Functional Limitations/Medical Restrictions & Permanent Disability

The strongest foundation in the correct determination of Occupational
Group Numbers has always been the Job Analyses, Essential Functions
Job Description and/or the RU-91. But as we integrate ACOEM Treatment
Guidelines with the California Code of Regulation Permanent Disability
Evaluation Guidelines, a new question can be asked: Are preventive
ergonomic tactics part of the current job functions?
Occupational Group Characteristics & Permanent Disability
Ratings
A well-rounded presentation by the Disability Evaluation Unit was
part of the Division of Workers Compensation 11th Annual Conference.

guidelines and the most recent list of cases related to all aspects
of Workers Compensation.
Job/Group Classifications: http://www.pdratings.com/GroupNumbers.htm
The correct group classification helps us determine the appropriate
modifications for the standard percentages of permanent disability.
This is done to reflect the particular physical demands of any given
occupation for the disability in question.
The group number is not based upon a "title." It is,
however, based upon the duties and functions performed within a
given group classification. The group classification for a general
type of occupation considers characteristics dealing with the level
of arduousness, standing/sitting requirements, demands addressing
functions of both the upper and lower extremities, the spine, vision,
hearing, etc. In general it considers the demands of the essential
functions of the job. It is the ‘essential functions’
and activities of an occupation within a given industry that take
precedent over the occupational title.
“If the occupation requires more than average use of the
injured part, the rating is modified upward; if the injured part
is relatively less important in that occupation, the rating is decreased.
In order to make this adjustment, the appropriate occupational group
must be determined.” Rating
Schedule Pages 1-5 and 1-6
“The Dictionary of Occupational Titles (DOT), compiled by
the US Department of Labor, was used extensively in the preparation
of the Schedule and will frequently be of assistance in determining
the functions of various occupations.” Rating
