Prior to submitting a Case Mix Data Request and/or Data Management Plan to CHIA, applicants are strongly encouraged to review all of the documents associated with data release (Data Request Form, Data Management Plan, template Data Use Agreement, and Data Fee Schedule/Fee Waiver Criteria) and to identify any questions they have concerning the forms or requirements. Applicants should expect to be required to agree to the provisions contained in the template Data Use Agreement posted on the CHIA website.
CHIA staff are happy to answer your questions prior to the submission of application documents and can provide assistance with, among other things:
For information about Case Mix and the application process, please email firstname.lastname@example.org.
In order to access CHIA data, applicants must submit a written Data Request Form, a Fee Remittance/Fee Waiver Form, and, if the request is for Case Mix Levels 2 and above, a Data Management Plan to CHIA using IRBNet. An IRBNet account can be created through https://www.irbnet.org/release/public/register.do and affiliated with the Massachusetts Center for Health Information and Analysis once logged in. See "How to Submit an Application on IRBNET."
Applicants seeking a fee waiver should submit their waiver request with their initial application. If the draft request depends on waiver of the data fees, the application materials will not be reviewed until the fee waiver issue is resolved.
After an initial screening to ensure the Data Request and Data Management Plan forms are complete, and that the applicant is seeking to use the appropriate dataset(s) for the proposed project, the applications will be forwarded to CHIA Legal to review for compliance with regulatory and other legal requirements.
CHIA Legal will assign Technical Specialists with expertise in data privacy and security to review the application materials. The Technical Specialists will work with applicants to refine Data Requests and Data Management Plans to ensure they meet legal and regulatory requirements. The length of this review period depends on the complexity of the request and the sensitivity of the data sought.
A Data Request will advance to CHIA’s Data Privacy Committee when the Technical Specialist has sufficient information to make a recommendation as to whether the data requested are the minimum necessary to achieve the proposed objectives and whether the risk of re-identification of individual patients has been minimized and appropriately balanced with project needs. The information required to make such recommendations includes, among other things: a description of the specific uses of the APCD data and of the proposed research methodology; specific justifications for the data elements requested; and, detailed information regarding any proposed linkages.
Similarly, the Data Management Plan is ready to advance for Data Privacy Committee review when the technical specialist has sufficient information to make a recommendation as to whether the applicant has submitted an adequate plan to safeguard any CHIA data that is provided. The information required to make such a recommendation is described in the Data Management Evaluation Guide.
Both the Data Request and the Data Management Plan must be ready to advance before the application can proceed for Committee review.
Pursuant to 957 CMR 5, CHIA’s Data Release Regulation, most non-governmental requests for data are required to be reviewed by an internal Data Privacy Committee and an external Data Release Committee. The committees are charged with determining whether the proposed use of CHIA data meet the criteria described in 957 CMR 5.06(10). The Executive Director considers the committees’ recommendations and approves or denies each request for data.
Prior to release of the data, the applicant must execute CHIA’s data use agreement. The data use agreement will include the approved application and data management plan. CHIA does not accept comments or revisions to its data use agreement. Data Applicants should consider consulting their legal or compliance office for DUA assessment before they submit an application for review. Please watch a short video, Data Use Obligations of Recipients of CHIA Data, intended for researchers holding and using CHIA confidential data.
IT processes the data extract.Once the extract is completed, CHIA ships the data extract with the final approval letter signed by the Executive Director to the data recipient.
The data contained in the APCD and Case Mix databases include highly sensitive personal information and Protected Health Information, the release of which is restricted by state and federal laws and regulations. The application process has been designed to help applicants prepare applications that will allow for the release of data while protecting patient privacy. For this reason, applicants should familiarize themselves with CHIA’s APCD and Case Mix Data Release Regulation (957 CMR 5.00) and the forms and other background information referenced above. CHIA looks forward to working with you to ensure that your application receives a thorough and timely review. Applicants should expect the application review and approval process to take several months, depending on the complexity or novelty of the request, and the amount of work required to ensure legal and regulatory requirements have been satisfied.
