What type of patient information might be kept outside of a Designated Record Set?

The type of patient information that might be kept outside of a Designated Record Set is typically non-clinical and not directly related to the patient's healthcare. Marketing correspondence falls into this category because it pertains to the promotion of services or products rather than the provision of medical care or treatment. As such, this document does not play a role in the clinical history of the patient or the decisions regarding their health care.

On the other hand, psychological evaluations, medical recommendations, and clinical intervention plans are directly related to a patient's treatment and are essential parts of their medical record. These documents reflect the care a patient receives and are included in the Designated Record Set, which comprises records that are maintained by a healthcare provider and are used to make decisions about the patient’s care. Thus, these clinical-related documents are central to the healthcare process and would not be kept outside the Designated Record Set.
