Area of Science:

  • Oncology
  • Health Informatics
  • Cancer Registry Management

Background:

  • Accurate cancer staging is crucial for patient care, research, and resource allocation.
  • Challenges exist in consistently capturing complete and accurate tumour stage data in cancer databases.

Purpose of the Study:

  • To detail the implementation process and lessons learned from establishing a tumour staging information system at a cancer centre.
  • To evaluate the accuracy of captured tumour stage data through a medical chart audit.
  • To explore the diverse applications of tumour stage information within a cancer centre setting.

Main Methods:

  • Retrospective review of an initiative to capture tumour stage information at a regional cancer centre.
  • Analysis of committee minutes, extracted staging data from the Oncology Patient Information System (OPIS), and a chart audit of 390 cases.

  • Review of Health Information Services workload statistics to identify uses of stage-related data.

    • Main Results:

    • Policies and procedures for capturing tumour stage were implemented in 1994, achieving 92% staging for qualifying cases in that year.
    • A 1998 audit revealed 71.5% of charts were completely staged; incomplete staging involved missing TNM or incorrect stage timing.
    • Physician-related errors occurred in 2-5% of cases, and data-entry errors in 3-6%.

    Conclusions:

    • Tumour stage information enhances patient clientele description for accreditation and aids researchers in identifying study populations.
    • Stage data supports targeted educational initiatives and assists administrators in resource needs estimation.
    • Overcoming resistance to data capture requires persistence, physician compliance strategies (e.g., reminder systems), institutional policies, and feedback on data utility.
