Step-by-step explanation:
Documentation from nursing or other allied health professionals' notes can be used to establish diagnoses. These diagnoses can include diseases or conditions that are inferred from the signs and symptoms recorded in the documentation. For example, if a patient presents with fever, cough, and shortness of breath, the documentation may indicate a diagnosis of pneumonia based on these symptoms. In addition, the documentation can help in identifying specific diseases or conditions that may require further testing or treatment, such as lab tests or imaging studies.
