DATA AMENDMENTS AFTER APPROVAL OR DATA DELIVERY
Researchers who receive data and realise that they need additional data files or fields included from one of the data files will have to submit an amendment. Changes to the cohort definition also require an amendment.
Researchers may request an amendment to their approved project by emailing the requested changes and a rationale for requesting the change (see below) to Researcher Liaison staff. Be sure to indicate that you are requesting an amendment to your approved project and include the project number and title. Researcher Liaison will forward the amendment to the Data Steward(s) for review and approval.
Please note that any amendments which involve changes to the cohort definition or which require additional data to be extracted will require a new cost estimate and a new Population Data BC Services Agreement. Amendments to the cohort definition in particular, can be both costly and time-consuming, so it is recommended that researchers make absolutely certain that their cohort definition is correct before submitting the Data Access Request (DAR). Researcher Liaison staff will assist researchers to define their cohort definition prior to the submission of the DAR for Data Steward review.
If the amendment does not fall into one of the categories below, please contact Researcher Liaison.
Amendment to data extract
Researchers who receive data and realise that they need additional data (i.e., additional data files, additional data fields, and/or additional years of data), will need to submit an Amendment to Data Extract request. There are three types of Amendment to Data Extract requests:
Researchers need to clearly indicate which type of amendment request they are making, and provide specific details on the additional data requested, e.g. the years, and/or fields, and or files. A detailed rationale for the request is also required.
Amendment to cohort definition
Researchers who receive data and realize that they need to request changes to the cohort definition(s) as originally approved, will need to submit an Amendment to Cohort Definition request.
Researchers need to describe in detail the changes they are requesting to their cohort(s) definition(s). A detailed rationale for the request is also required.
Amendment to extend the data retention date
Researchers are initially permitted access to the data extract provided by Population Data BC for up to two years after Population Data BC provides the first set of data, as long as privacy conditions are met. Researchers who need additional time to analyse their data will need to submit an Amendment to Extend the Data Retention Date request.
Researchers need to provide a rationale for extending the data retention period, and confirm that they have accompanying ethics renewal for the period, if applicable.
Submit all amendment requests via email to Researcher Liaison. Researcher Liaison staff will coordinate the review of the amendment request by the Data Steward(s).
Data preparation errors
If Population Data BC has made an error in preparing data for a research project, the request is placed at the front of the work queue and prepared as quickly as possible.
