Data Quality Toolbox for Registrars MCSS Workshop December 9, 2003 Elaine Collins
Quality Data Toolbox • Artisan Registrar • Medium Computerized data • Raw Materials Medical information • Shaping tools Knowledge, skills • Directions Standards • Measuring tools Editing “tools” • Final Product Cancer record • Goodness Match to standards
Quality Data - Goodness • Accurate • Consistent • Complete • Timely • Maintain shape across transformation and transmission
Measuring Tools • Reabstracting studies • Structured queries and visual review • Text editing • EDITS • MCSS routine review
Exercises • MCSS reabstracting study – 2003 • Sites: Breast, Corpus uteri, Lung, Melanoma, Testis, Soft tissue sarcoma • 2000 diagnosis year • 12 facilities • Review of reported data – Structured query • Review of reported data – Text editing
Reabstracting Studies • Compares original medical record with reported cancer record • Considered the “gold standard” • Labor-intensive; all records used at initial abstracting may not be available; biased by reabstractor’s training and skills
Structured Queries • Compares coding across series of records sorted by selected characteristics • Useful for finding pattern discrepancies across many records • Manual process; some comparisons may be converted to automated edits
Text Editing • Compares text with coded values for individual records • Useful for immediately identifying coding problems • Manual process; most effective on completion of each individual case
EDITS • Checks range validity for many fields, comparability of few fields for individual records • Automated process, can be applied on completion of each record or on preparation of batch report; warnings and over-rides are alternatives to failures • Expansion of interfield edits requires careful logic
Edits Analysis • Edits to be included in MCSS Set • Edits in Hospital/Staging Edit Sets – C edits are included in confidential data set • No Text Edits displayed • Criteria • Valid codes/dates • Alpha/numeric • Timing • Interfield comparisons • Absolute conditions
MCSS Review • Requests values for missing or unknown data; resolves conflicts between data items from multiple facilities and between data items updated by single facility • Allows incorporation of information from multiple facilities • Review for limited number of conditions

Data Inputs • Patient data from facility systems • Medical record reports and notes • Pathology reports • Staging forms • Communication with physician offices • Communication with other registries • Communication with patients
Process Inputs • Registrar training, knowledge, skills • Coding standards – ICD-O-3, COC, AJCC, SEER, NAACCR • Interpretations of standards – I&R, SEER Inquiry, Ask NAACCR • Medical literature – printed and online • Registry software data implementations
Sources of Error • Patient data from facility systems • Medical record reports and notes • Pathology reports • Staging forms • Communication with physician offices • Communication with other registries • Communication with patients
Sources of Error • Registrar training, knowledge, skills • Coding standards – ICD-O-3, COC, AJCC, SEER, NAACCR • Interpretations of standards – I&R, SEER Inquiry, Ask NAACCR • Medical literature – printed and online • Registry software data implementations
Types of Errors • Missing/conflicting data • Shared data errors • Timing/coding errors • Standards and interpretations – ambiguities, omissions, confusions, contradictions • Discrepancies among local/central registry practice and national standards
Software Implementations • Discrepancies between implementations and national standards • Lack of registrar knowledge/training on correspondence between registry and exported data • Logic errors in matching registry data to reporting formats • Conversion errors
AJCC Staging Dilemma • Are pathologic nodes required for pathologic stage grouping? • How do Minnesota registrars answer this question?
Collaborative Staging • Provides specific rules for coding known vs unknown staging elements • Accommodates “best” stage for AJCC stage assignment
AHIMA 75th Annual ConferenceOctober, 2003 Minneapolis:Coming Events • Data mining • ICD-10-CM • SNOMED • Natural language processing
AHIMA 75th Annual ConferenceOctober, 2003 Minneapolis: Challenges • What is our professional purpose? • How do we envision ourselves as professionals?
Foundation for Quality Data • Registrar’s commitment to registry purpose • Registrar’s knowledge, understanding of cancer data • Registrar’s management of communication technologies • Registrar’s advocacy for data use
SUMMARY • Consistent recording and reporting of quality cancer data requires commitment. • Routine and regular review of data patterns facilitates data knowledge and quality. • Passing EDITS assists but does not ensure data quality. • Data standards change, use the manuals. • Welcome Collaborative Stage.
