princess margaret hospital
Princess Margaret Hospital
  • Princess Margaret Hospital opened in 1958 in Toronto, Canada
    • Cancer Registry data collection from the beginning
    • Now a Comprehensive Cancer Centre Treatment Facility
  • As of November 1998, PMH became part of the University Health Network along with 2 Acute Care Facilities
    • All Oncology Services moved to PMH
  • Treat over 10,000 new cases

per year seen at PMH

  • 1 Cancer Registry Analyst
  • 1 Information Management Analyst

historical case finding methods
Historical Case Finding Methods
  • 1980-1997- Manual process, review of in-patient and out-patient lists and list of new chart numbers assigned
    • Charts were pulled for abstracting
    • Manual process was used to identify second primaries
  • 1998-2002- Demographics from scheduling lists downloaded into Cancer Registry software
    • List of all appointments not just new patients, including non-neoplastics
    • Monthly lists were reviewed to determine cases to process
history of staging at pmh
History of Staging at PMH
  • The collection of staging information began when PMH was opened in 1958.
  • Initially captured TNM Staging for Breast, Ovary, Head & Neck
    • Completed by Physicians and Registry staff
    • Additional sites were added.

History of Staging at PMH- (cont’d)
  • In the late 1990’s MD participation in staging began to decline.
  • In 2001, Cancer Registry Committee, Staging

& Education Sub-Committee and VP/COO approved Physician staging for all stageable sites using UICC-TNM.

Purpose: To obtain cancer classification and staging data in an accessible format for integration into the cancer registry so that it can be used for research in an acceptable timeframe

development of physician on line staging application
Development of Physician On-Line Staging Application
  • A committee was established with the task of developing an on-line staging tool for physicians to enter all the UICC-TNM information on-line through a web-based tool that would be accessible by Cancer Registrars and integrated into the Cancer Registry database
    • An auditing process was required to track completeness
physician on line staging application audit process
Physician On-Line Staging Application-Audit Process
  • Physicians given 3 months from the time of the first appointment date to complete the staging
  • After the 4th month if the staging is still not complete, the names of the physicians with incomplete cases are sent to the Department Head
  • After the 5th month, if the staging is still not complete, the names of the physicians with incomplete cases are sent to the VP /COO

  • Physician Staging
  • Auditing
current case finding methods physician on line staging application
Current Case Finding Methods-Physician On-Line Staging Application
  • Since July 2002, physicians required to classify and stage all new patients to PMH
  • Cases for Physicians to stage automatically downloaded from patient scheduling system
    • New Ambulatory Patients
    • Surgical Patients
    • In-Patients
enterprise data warehouse edw
Enterprise Data Warehouse (EDW)
  • EDW integrates information from various transactional systems within the UHN in order to provide a single environment that facilitates analysis for both the corporate and research communities.
  • Not just oncology cases, institution wide
  • Currently houses data from over 14 transactional systems including:
    • cancer staging, patient demographics, visits, pharmacy, radiation therapy, surgery
data collection
Data Collection
  • All invasive tumours except skin (C44) in 8000-8110 histology range
  • All in-situ tumours except CIN, PIN, VIN,VAIN
  • All tumours of uncertain malignant potential
data elements collected
Data Elements Collected
  • Patient identification
  • Cancer identification
  • Stage of disease
    • at diagnosis
    • at relapse/progression
  • Treatment

advantages of e registry
Advantages of E-Registry
  • The demographics are downloaded. These are tedious to enter: name, full address, date of birth
  • First contact date gives a hint as to where to start in reviewing the electronic chart which is UHN wide, not oncology specific
  • Identifies treatment given at UHN
  • Can specify what types of cases to download
    • Malignant, in-situ, benign, non-neoplastic
  • Physician selects generic primary site
    • Can pull out certain cases if required

Staff cannot think of any disadvantages

next steps
Next Steps
  • Audit to compare Physician staging with Registrar staging
  • Assess time required to abstract between old and new methods
  • Look at feasibility of Collaborative Stage
uses of cancer registries outcomes
Uses of Cancer Registries-Outcomes
  • Measuring the impact of the delivery of care is critical
  • Stage specific survival is an outcome measure
    • Stage at initial diagnosis is used as an indicator for cancer control programmes
    • Recurrence rates
    • Disease-free intervals
data access
Data Access
  • Access to data requires approval of the Research Ethics Board (REB)
    • Request submitted to the Cancer Registry & Data Access Committee
      • Requires all Department Head signatures
      • Participation on the study of relevant Departments
      • Approval of Cancer Site Group leader
    • If approved submitted to REB
site specific databases
Site Specific Databases
  • Lymphoma
  • Leukemia
  • Central Nervous System
    • Discontinued for 2004
  • Seminoma
  • Thoracic
data submissions provincial
Data Submissions-Provincial
  • PMH Cancer Registry data is submitted to Cancer Care Ontario
  • CCO operates the Ontario Cancer Registry
    • The Ontario Cancer Registry is a computerized database of information on all Ontario residents who have been newly diagnosed with cancer All new cases of cancer are registered, except non-melanoma skin cancer. More than 1.3 million cases have been registered since 1964
data submissions federal
Data Submissions-Federal
  • Each Province and Territory has a Cancer Registry
  • Each P/T submits their data to Statistics Canada, located in Ottawa
    • Data is used by the Public Health Agency of Canada as well as other researchers.
  • The Physician- on-line Cancer Staging application drives the registry’s case finding process
  • The development of the E-Registry tool and incorporation into the EDW has enabled data to be rapidly accessed, which greatly facilitates outcome analysis for both administrative and research purposes.

The Cancer Registry is like an iceberg…The tip of the iceberg is what is visible to all people, but the largest

portion of the iceberg remains under the water and unseen by most. Underneath the iceberg is a vast community of healthcare professionals, national standards, and system realities that drive

the registrar towards the collection and management of quality data.
