Understanding the fundamentals of HIPAA, Protected Health Information (PHI), and Personally Identifiable Information (PII) is essential for conducting compliant and ethical research, especially within academic institutions like Northwestern University. This guide offers a comprehensive overview of these concepts, emphasizing their relevance in research activities, and provides clarity on the regulatory landscape, including when and how HIPAA applies, and the procedures for obtaining necessary authorizations and waivers.
Research involving health information requires careful adherence to federal and institutional regulations designed to protect patient privacy and confidentiality. Recognizing the distinctions between PHI and PII, understanding the scope of HIPAA’s Privacy and Security Rules, and knowing the processes for securing authorization or waivers are critical steps in ensuring compliance.

Additionally, understanding how data analytics strengthens healthcare decision-making can be gained through learning about data-driven healthcare improvements.
What is the Health Insurance Portability and Accountability Act (HIPAA)?
HIPAA, or the Health Insurance Portability and Accountability Act, is a key federal law enacted to safeguard patient information from inappropriate disclosures that could jeopardize their privacy, employment prospects, or insurance coverage. Central to HIPAA are the Privacy and Security Rules, which establish standards for protecting sensitive health data. The Privacy Rule specifically defines protected health information (PHI) as any health data that can identify an individual, while the Security Rule sets criteria for securing electronic health records against unauthorized access and breaches.
At Northwestern University, the Institutional Review Board (IRB) plays a vital role in overseeing research involving PHI. When research involves the review or use of medical records, the IRB or a designated Privacy Board must assess whether the study complies with HIPAA. The Northwestern IRB Office provides templates and guidance for obtaining informed consent that incorporates HIPAA authorization, with additional details available on the Informed Consent and Waivers of Consent webpage.
Researchers may secure approval to access and utilize PHI through two primary methods: obtaining a signed consent form that includes HIPAA authorization or securing a waiver of authorization from the IRB. The IRB’s approval letter will specify the authorized procedures. It’s important to note that the applicability of HIPAA regulations depends on specific conditions, such as whether the data originated from medical records or healthcare providers. For example, reviewing PHI from a hospital record generally triggers HIPAA compliance, whereas data obtained from publicly available sources or previously reviewed research records may not be subject to HIPAA. Still, other privacy laws and research regulations may apply, underscoring the importance of consulting with the IRB for clarification.
When does HIPAA Apply?
HIPAA regulations come into effect whenever protected health information is used or disclosed in the context of research. Common scenarios include:
- Reviewing PHI during participant recruitment, such as examining medical records or data stored in the Enterprise Data Warehouse (EDW) to identify eligible candidates or contact potential participants.
- Accessing or recording data from medical records or EDWs specifically for research purposes.
- Checking whether individuals, including future clinic patients, meet research eligibility criteria.
In these contexts, the Privacy Rule mandates that researchers obtain explicit authorization from individuals before using or sharing their PHI, typically through signed HIPAA authorizations. These can be obtained electronically, facilitating easier compliance. However, in certain situations, the IRB may grant a waiver of authorization, allowing the research to proceed without individual consent under strict conditions.

What is Protected Health Information (PHI)?
PHI encompasses any health-related data that contains any of the 18 identifiers specified by HIPAA, which can be used to directly or indirectly identify an individual. This includes information created or received by healthcare providers that pertains to a person’s health status, provision of healthcare, or payment for healthcare. PHI remains protected for fifty years after an individual’s death, reflecting its sensitive nature.
HIPAA’s 18 Identifiers
HIPAA delineates 18 specific identifiers that, when linked to health information, render the data as PHI. These identifiers include but are not limited to:
- Names and all geographical details smaller than a state (excluding certain ZIP code restrictions)
- Birth dates, admission/discharge/death dates, and age over 89
- Contact details such as phone, fax, and email addresses
- Social Security and medical record numbers
- Health plan beneficiary and account numbers
- Vehicle and device identifiers
- Web URLs and IP addresses
- Biometric data and photographic images
- Any other unique number, characteristic, or code that can identify an individual
It is crucial to understand that derivatives or parts of these identifiers also count as identifiers under the Safe Harbor method for de-identification, as per HHS guidance. For comprehensive details, consult the official list of HIPAA identifiers.
What is Personally Identifiable Information (PII)?
PII refers to any data that can identify an individual but is not classified as PHI under HIPAA. It is typically used in research contexts unrelated to healthcare services, such as surveys or interviews, and is protected under other federal and state privacy laws. The critical difference is that PII does not relate directly to health status or healthcare provision, which are the core criteria for PHI.
Examples of PII
Examples include personal demographic data like name, address, or phone number, collected independently of medical records. Such information is often used in research for recruitment or follow-up but does not fall under HIPAA’s scope unless linked to health data. Despite this, PII remains subject to privacy regulations, emphasizing the importance of safeguarding participant confidentiality.

HIPAA Authorization
Any research activity that involves the use or disclosure of PHI must comply with HIPAA’s Privacy Rule, which requires obtaining explicit authorization from the individual concerned. This authorization must include specific elements mandated by law, such as a clear description of the information to be used or disclosed, the purpose, and the individual’s signature and date.
The Northwestern IRB provides standardized consent/authorization templates that incorporate all necessary HIPAA elements. These templates facilitate compliance and streamline the process of securing participant consent. Investigators should review Northwestern’s policies on research privacy and confidentiality for detailed guidance on when HIPAA authorization is necessary.
Obtaining an Individual’s HIPAA Authorization
Researchers must secure signed authorization forms from participants before using their PHI. These forms can be obtained physically or electronically, provided they contain all the core elements specified by HIPAA. The IRB’s approval will specify whether the authorization is required or if a waiver is granted. Participants also have the right to revoke their authorization at any time, which must be documented properly. For more detailed procedures, consult the Research Privacy and Confidentiality Policy.
Revocation of Authorization
Participants can withdraw their authorization in writing at any time. If the study involves sensitive information like mental health or developmental disabilities, revocation must be witnessed and signed by an authorized person to confirm identity. Northwestern provides a Revocation Template Letter to facilitate this process.
Waiver of HIPAA Authorization
In certain research scenarios, the IRB may approve a waiver or modification of HIPAA authorization requirements. The criteria for granting such waivers include minimal risk to privacy, impracticality of obtaining authorization, and necessity of access to PHI for the research purpose. The IRB evaluates these requests through a detailed checklist, ensuring compliance with federal regulations outlined in HRP-441.
A waiver might be granted when obtaining individual authorization is impossible (e.g., retrospective record reviews), or when a partial waiver allows access to contact information without full authorization. Requests for waivers or modifications must include a thorough justification demonstrating how the study meets all regulatory criteria. For specific procedures, visit the HIPAA waiver application guidelines.
