The following is a summary of the above-referenced Privacy Impact Assessment (PIA), including a brief background, key findings, and risks and recommendations as applicable. See our Contact page to find information on how to contact the Ontario Health Privacy Office should you have any questions.

Background 

As required by the Personal Health Information and Protection Act (PHIPA) and by the Ontario Health (Cancer Care Ontario) Privacy Policy, PIAs were completed for the Interactive Symptom Assessment and Collection (ISAAC) Application.  

This document provides is a summary of PIAs conducted on the ISAAC solution. This PIA summary includes background on the ISAAC Application and also notes Ontario Health's progress in implementing the recommendations contained in the PIA addendum. 

Key Findings

This PIAs concluded that Ontario Health has the authority to carry out the operations of the ISAAC Application as a Health Information Network Provider (HINP) pursuant section 6(2) of O.Reg. 329/04 and may collect and use the personal health information in ISAAC Replication Database as a Prescribed Entity pursuant to section 45 of PHIPA. In addition, Ontario Health is an Electronic Service Provider (ESP) pursuant to section 6(1) of O.Reg. 329/04 and section 10(4) of PHIPA with respect ePREM services it provides to ISAAC sites through its third-party service provider NRC Health. Lastly, Ontario Health is a PHIPA Agent pursuant to section 17 of PHIPA with respect to consent management (fulfilling patient request to no longer participate in ISAAC); Fulfilling individual access request; and Request related to corrections.

The ISAAC Application captures information on the patients' symptoms and functional status using various self assessment tools such as PROMs. Self-assessment information may be entered directly by a patient into an ISAAC kiosk at an ISAAC Site or using personal devices such as home computers through a secure website, through TeleISAAC (though Tele-ISAAC functionality is currently not in use) or recorded on paper and subsequently entered into the ISAAC Application by health care providers. Functional status scores may also be entered into the ISAAC application by clinicians/administrators. Updates to scores may be performed manually by health care workers or ISAAC Site staff using the ISAAC Application.

The ISAAC Application enables the systematic collection PROMs from patient populations at participating sites for a variety of purposes, including the support of local quality improvement and research initiatives, and the evaluation of the appropriateness and effectiveness of surgical interventions.

ISAAC is integrated with Admission Discharge Transfer (ADT) which has helped automated the patient enrolment as well as updates to patient demographic information. The automation will occur through the integration of the hospital's Health Information System (HIS) or Electronic Medical Record (EMR) through the HL7 message. HL7 integration with ISAAC has enabled bi-directional and ini-directional data transfers between ISAAC and the ISAAC site's HIS or EMR.
