Process Control Based Approach to Ensuring Quality Control in Data Requests

This paper discusses how a process control-based approach can ensure quality control in data requests for the Missouri Cancer Registry. It covers the application of process control and process quality engineering, a case study of data requests, and the results obtained. The importance of continuous quality improvement and the lessons learned from implementing this approach are also discussed.

Presentation Transcript

  1. Process Control Based Approach to Ensuring Quality Control in Data Requests G. White, S. Vest, J. Jackson-Thompson Missouri Cancer Registry University of Missouri-Columbia Supported by CDC/NPCR Cooperative Agreement #U55/CCU721904-05 and a contract between the University of Missouri and the Missouri Department of Health and Senior Services

  2. Overview • Process Control and Process\Quality Engineering • Application to Registry Operations • Case Study • Missouri Cancer Registry Data Requests • Methods • Results

  3. What is Process Control? • Process/Quality Engineering • Design error opportunities out of the system • Evolutionary Process • Continually monitoring measures of quality • Identifying error opportunities • Updating system

  4. Continuous Quality Improvement • Modern manufacturing relies on CQI • Began at Western Electric in the 1930’s • J.M. Juran and Edward Demming • Quality Management • Statistical Process Controls • WWII and Post-war • ISO certification

  5. What is Quality • Quality is the inverse of variability • High Quality = Little Variation • Low Quality = Lots of Variation • “On-Target with Minimum Variation” • Minimum Variation typically more important than on target in process/quality control • Customer wants predictability • “You Get What You Pay For”

  6. How this Applies to Registry Operations • Registries don’t manufacture tangible products – produce information • Production relies on a process • Optimization through Process Engineering • Work-flow design that minimizes error opportunities is the most efficient

  7. Case Study:Missouri Cancer Registry Data Requests • How Data Requests are received • Oral • Written • Electronic • How Data Requests are filled • SEER*Stat • Customer Relations • Filled Requests returned

  8. What Went Wrong • Data requests could take a day to weeks to fill • Mistakes made in filling requests, required multiple attempts to meet customer’s needs • No clear procedure for the process • No measures of quality available

  9. Poor Process Design • Thought we had an “efficient” process • Example of “efficient” design not being optimal • No accountability • No process monitoring • No feedback to improve process

  10. Observations • No one person was responsible for receiving and approving data requests • No tracking system for these requests • Prose descriptions of data requested • Confusion resulted in multiple attempts to fill requests

  11. Defining The Problems • Two biggest problems • No tracking system – couldn’t tell where in the process a request was. • Unclear requests – customer requests were unclear and difficult to translate in to a SEER*Stat query.

  12. The Solutions • A tracking system with clearly delineated responsibilities • A “caretaker” • Retain Multiple Approvers • A clearly designed data request form based on SEER*Stat

  13. Results • New form substantially reduced confusion in filling data requests • New procedures and log file helped improve tracking and fill-time consistency • Higher quality in terms of reduced errors in the requests and in fill-time.

  14. Other Results • May seem more complex and slower • Reducing error opportunities increased efficiency • Continual Improvement is an important part of new system

  15. Conclusion and Lessons Learned • This process control-based approach is easily implemented • Resulted in noticeable improvement • Requires user feedback for continuous improvement

  16. Future Prospects • This approach can be applied to all areas of operations • By focusing on designing work-flow to minimize error opportunities you automatically increase efficiency
