I want to say D. Not sure here

Which of the following is true in regard to limited data sets?
A. Patients must authorize the use of limited data sets.
B. Those who receive limited data sets can pass them on without restrictions.
C. Limited data sets can’t include a patient’s city, state, age, and birth date.
D. Limited data sets contain some individual identifiers.

I think D is right.

To determine which option is true in regard to limited data sets, we can analyze each option individually:

A. Patients must authorize the use of limited data sets: To find out if this is true, we can refer to the rules and regulations governing limited data sets. In the United States, the Health Insurance Portability and Accountability Act (HIPAA) provides guidelines for the use and disclosure of protected health information. According to HIPAA, a limited data set is a de-identified dataset that doesn't contain direct identifiers, such as names and addresses. However, a patient's authorization is not required for the use of limited data sets. Therefore, option A is not true.

B. Those who receive limited data sets can pass them on without restrictions: To verify this statement, we can again refer to HIPAA. The regulations state that the use and disclosure of limited data sets should be in accordance with a data use agreement. The data use agreement imposes restrictions on the recipient of the limited data set, including restrictions on further disclosure. Therefore, option B is not true.

C. Limited data sets can’t include a patient’s city, state, age, and birth date: This statement is partially true. Limited data sets do not contain direct identifiers, such as names, addresses, and Social Security numbers. However, some indirect identifiers are allowed in limited data sets, including geographic information that is more general than city or state, and age in broad categories, but not exact birth dates. Therefore, option C is partially true, but it's important to note the specific restrictions on these indirect identifiers.

D. Limited data sets contain some individual identifiers: This statement is true. Limited data sets do contain some individual identifiers, but these identifiers are limited to a subset of direct identifiers that are necessary for research, public health, or healthcare operations. The specific identifiers that can be included in a limited data set are defined by HIPAA regulations.

Based on this analysis, option D is the correct answer to the question.
