Capturing tumour stage in a cancer information database.

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.
