Princess Margaret HospitalPrincess 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

PMH Cancer RegistryPMH Cancer Registry

• Hospital-based Cancer Registry, that provides a database for the gathering and dissemination of diagnosis, staging, treatment, and follow-up information for cancer patients seen at PMH.

• Data Collection standards: Use the Registry, Operations and Data Standards (ROADS) from the Commission on Cancer beginning with the 1998 data.

Historical Case Finding MethodsHistorical 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

• 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 PMHHistory of Staging at PMH

• 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

Physician On-Line StagingPhysician On-Line Staging

• 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

• 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

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 CollectionData 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

PMH E-Cancer Registry

Advantages of E-RegistryAdvantages 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 StepsNext 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-OutcomesUses 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 Submissions-ProvincialData 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-FederalData 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.

ConclusionsConclusions

• 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.
