Short answer:
The difficulty in finding material on the subject is because there is no such differentiation in the literature.
Long answer
Edited with question edit.
This is all really a use case.
But in this exercise, they are logically divided into your project, grouping the use cases by type.
For example, a possible interpretation of this separation:
The use cases concept, are those that do not exist in practice, they exist only in thought. In this case, there are two that would apply. For example, searching for patient records facilitates two other use cases, but in practice, it is not a use case that some actor initiates. In practice it is within two other use cases and the separation just simplifies the modeling.
Now the cases of process use, would be those that facilitate or standardize a process. For example, mark or cancel query. This type of use case can generate data for report use cases.
And the report use cases, would be the use cases that generate the report itself. For example, the "Query Schedule" use case would allow a physician to view a report based on the process of dialing and canceling appointments.
