Uses of the WCIS database
At initial meetings of the FROI/SROI Task Force, participants requested background
information concerning uses of the WCIS database. This e-news describes current
projects and also includes examples of how the database has been used since
A. Major projects using WCIS data that are currently underway or about to
be undertaken by DWC include:
1. Timeliness of Payments Reports by Claim Administrator have been requested
by a member of the California legislature. For this analysis, DWC needs
and is updating trading partner profiles that contain accurate supplemental
claim administrator lists.
2. DWC is analyzing all available information about permanent disability
claims from data in the WCIS in connection with DWCs mandate from
the legislature. SB 899 requires that empirical data on lost earnings by
permanently disabled workers be incorporated into future versions of the
disability rating schedule on regular five-year intervals.
3. Beginning later this year, illness and injury incidence rates for workers
in California industries will be calculated on a quarterly basis.
4. In the near future, California claim administrators who report complete
and accurate information to the WCIS will no longer have to submit the paper
Annual Report of Inventory to DWCs Audit Unit. The Audit Unit will
use information about claim administrator activity from the WCIS instead
of analogous data from the Annual Report of Inventory.
B. Several other significant work-in-progress items are pertinent to the
work done at DWC with respect to the WCIS. Most importantly, DWC has:
C. Examples of how DWC has used the WCIS database since 2005 include:
1. For the Employment Development Department (EDD) -- DWC compared
State Disability Insurance (SDI) claims with Social Security Number matches
in the WCIS database. Moreover, EDD and DWC have agreed that DWC should perform
matches like this on a regular basis for the SDI.
2. For the Workers' Compensation Insurance Rating Bureau (WCIRB) -- DWC performed
two analyses: first, DWC examined the number of total reported injuries and
denied claims in 2003 and 2004, for both insured and self-insured employers,
with the purpose of estimating the impact of reform legislation. DWC also
provided the Bureau with a data matrix/report on the total count of claims,
by year/month, by date of injury and employer/claim administrator knowledge
for all claims in the WCIS database for further analysis and study by WCIRB
3. For the Bureau of State Audits -- DWC analyzed FROI data for selected
companies involved in the Bay Bridge major construction project, including
the use of:
4. For the Department of Health Services (DHS) -- DWC
provided DHS with data files or extracts for injuries related to asthma, carpal
tunnel syndrome, and silicosis for use by DHS to monitor, further analyze
and follow up work on these injuries.
o the FEINs reported by construction companies;
o the various company names/subsidiary names reported by business entities;
o the class codes used by insured and self-insured business entities.
5. For DIRs Division of Occupational Safety and Health (DOSH) --
DWC provided data for selected injury types by part of body, such as eye-related
injuries. DWC also provided DOSH with an analysis of heat-related injuries/illnesses
to agricultural workers and an analysis of occupational back and back-related
injuries in California hospitals, by part of body and cause of injury.
6. For law enforcement entities -- DWC used the WCIS occasionally in connection
with fraud-related work.
7. For university researchers -- In 2005, DWC supplied a large and complicated
data extract (representing 73,000 claims) to a UCSF researcher for the Nurse
Workforce Initiative Study. In 2006, a much larger data extract was provided
to a researcher at Boston University to conduct an analysis supported by
Commission on Health and Safety and Workers' Compensation (CHSWC). Sample
data from the WCIS database were also used for a medical access study contracted
by the DWC with UCLA. About 6,000 claims with injury data during a specified
period in 2005 were extracted from WCIS for purposes of the UCLA study.
8. For the public -- the WCIS webpage (http://www.dir.ca.gov/DWC/WCIS.htm)
contains descriptive tables that provide information to the public about
important characteristics of workers compensation claims in California,
such as claims by year and by part of body, nature of injury, cause of injury,
type of insurer, age and gender. A brief study on Age, Gender and
Insurer Segment Characteristics of Workers Compensation Claimants
is also posted.
9. For DWCs Administrative Director (AD) and other internal uses
-- DWC regularly performs ad hoc analyses and data queries that are used
to assess the performance of the workers compensation system in the
state and help the AD to make informed policy decisions affecting the industry.
DWC has a set of point and click or user-friendly menu screens
that allow staff to analyze selected WCIS information about:
a. injury characteristics, at a particular point in time or for
selected time periods, by part of body, nature and cause of injury;
b. workers demographic and work characteristics;
c. claims by county and geographic region;
d. claims by benefit category;
e. claims by insurer type;
f. timeliness of benefits delivery; and
g. cost of injuries by gender, age at injury, nature of injury and benefit
