Development of a Coding and Crosswalk Tool for Occupations and Industries.

ABSTRACT: Introduction:Job coding into a standard occupation or industry classification is commonly performed in occupational epidemiology and occupational health. Sometimes, it is necessary to code jobs into multiple classifications or to convert job codes from one classification to another. We developed a generic tool, called CAPS-Canada (http://www.caps-canada.ca/), that combines a computer-assisted coding tool covering seven International, Canadian and US occupation and industry classifications and an assistant facilitating crosswalks from one classification to another. The objectives of this paper are to present the different functions of the CAPS-Canada tool and to assess their contribution through an inter-rater reliability study. Method:The crosswalk assistant was built based on a database of >30,000 jobs coded during a previous project. We evaluated to what extent it would allow automatic translation between pairs of classifications. The influence of CAPS-Canada on agreement between coders was assessed through an inter-rater reliability study comparing three approaches: manual coding, coding with CAPS-Canada without the crosswalk assistant, and coding with the complete tool. The material for this trial consisted of a random sample of 1000 jobs extracted from a case-control study and divided into three subgroups of equivalent size. Results:Across the classification systems, the crosswalk assistant would provide useful information for 83-99% of jobs (median 95%) in a population similar to ours. Eighteen to eighty-one percent of jobs (median 56%) could be entirely automatically recoded. Based on our sample of 1000 jobs, inter-rater reliability in occupation coding ranged from 35.7 to 66.5% (median 53.7%) depending on the combination of classification/resolution. Compared with manual coding, the use of CAPS-Canada substantially improved inter-rater reliability. Conclusion:CAPS-Canada is an attractive alternative to manual coding and is particularly relevant for coding a job into multiple classifications or for recoding jobs into other classifications.

Project description:ObjectiveAlthough Medicare assessment files will include Standardized Patient Assessment Data Elements from 2016 forward, lack of uniformity of functional data prior to 2016 impedes longitudinal research. The purpose of this study was to create crosswalks for postacute care assessment measures and the basic mobility and daily activities scales of the Activity Measure for Post-Acute Care (AM-PAC) and to test their accuracy and validity in development and validation datasets.MethodsThis cross-sectional study is a secondary analysis of AM-PAC, the Inpatient Rehabilitation Facility Patient Assessment Instrument, the Minimum Data Set, and the Outcome and Assessment Information Set data from 300 adults receiving rehabilitation recruited from 6 health care networks in 1 metropolitan area. Rasch analysis was used to co-calibrate items from the 3 measures onto the AM-PAC metric and to create look-up tables to create estimated AM-PAC (eAM-PAC) scores. Mean scores and correlation and agreement between actual and estimated scores were examined in the development dataset. Scores were estimated in a cohort of Medicare beneficiaries with hip, humerus and radius fractures. Correlations between eAM-PAC and Functional Independence Measure motor scores were examined. Differences in mean eAM-PAC scores were evaluated across groups of known differences (age, fracture type, dementia).ResultsStrong correlations were found between actual and eAM-PAC scores in the development dataset. Moderate to strong correlations were found between the eAM-PAC basic mobility and Functional Independence Measure motor scores in the validation dataset. Differences in basic mobility scores across known groups were statistically significant and appeared to be clinically important. Differences between mean daily activities scores were statistically significant but appeared not to be clinically important.ConclusionAlthough further testing is warranted, the basic mobility crosswalk appears to provide valid scores for aggregate analysis of Medicare postacute care data.ImpactThis study reports on a method to take data from different Medicare administrative data sources and estimate scores on 1 scale. This approach was applied separately for data related to basic mobility and to daily activities. This may allow researchers to overcome challenges with using Medicare administrative data from different sources.
