Public Health Analytics

Public Health Analytics provides health analytics support, standards and coordination to BCCDC, the provincial health authorities and the BC Ministry of Health.

Public Health Analytics supports BCCDC program areas across all components of the surveillance cycle, from data acquisition and data management, to data analysis and dissemination. We provide solutions for presenting surveillance information to those who need to know in order to undertake public health action.

Public Health Analytics works closely with BCCDC program areas to ensure data used for surveillance is of the highest quality, that caveats and data limitations are understood and that processes used to manage and analyse data are standardized and efficient. 


We have standardized and automated surveillance processes to enable efficiencies and cross-coverage for routine surveillance activities that support surge capacity in time of heightened public health need.


We are also looking to the future and positioning BCCDC to be able to meet the computationally higher processing demands of linked data, building robust linked public health data stores with strong, active, data governance frameworks, and making data more accessible to stakeholders in readily analyzable formats.

Data products

Data warehouse 

The Public Health Reporting Data Warehouse (PHRDW), is a data warehouse that links data sources of public health importance to provide a de-identified view of an individual's health experience. 


PHRDW is used to conduct real-time public health surveillance in BC in order to identify changing patterns of disease activity. PHRDW matches patients from different source systems and applies data cleaning algorithms and transformations that make data analysis-ready.


PHRDW provides a platform for reliably linking data from multiple sources to the same individual. 

Who uses it?

Public health epidemiologists, statisticians and analysts at provincial and regional levels use PHRDW as do staff at the BCCDC Provincial Laboratory.


What kind of data is available?

Subsets of themed data – or data marts – have been created to support surveillance of enteric diseases, vaccine preventable diseases, chronic diseases, respiratory diseases, environmental health conditions, sexually transmitted and blood borne infections. A data mart containing only Panorama data has also been developed to allow ad-hoc querying of other communicable diseases, including TB cases and their contacts.


The first data mart was developed in 2011, and new marts continue to be created. Data includes information collected on notifiable diseases per the provincial surveillance forms, laboratory tests, and deaths.


New data sources continue to be added as data sharing agreements are put in place.


How do you access it? 

PHRDW governance bodies approve the development of each data mart, including the type and level of access users will have. 


A PHRDW User Access Request Form is available for PHSA users or through PHRDW Power Users for regional health authorities. 


How is data linked?

Data is linked using a custom person matching algorithm with match rates validated between 99.1% and 100%, depending on the subsets of records contained in the mart. This automates a traditionally very time consuming activity, freeing up analytic resources and standardizing process.


Can I use the data for research?

Under the PHRDW data governance model, research is not a standard purpose but can be authorized with additional approvals from source system data stewards.


How is data protected in PHRDW?

The platform uses PHSA enterprise architecture standards, is built to be scalable, and has passed a provincial Privacy Impact Assessment and  a Security Threat and Risk Assessment.


Both provincial and regional views of data are available, allowing health authorities to view a subset of records for clients living in or receiving services from a particular Health Authority.


How is PHRDW managed?

It is operated by the BC Centre for Disease Control and PHSA Performance Management and Reporting under a data governance framework inclusive of all data contributors.
