Clinical data can be collected through various methods: - Electronic Health Records (EHRs): These are digital versions of patients' paper charts that provide real-time, patient-centered records accessible instantly and securely to authorized users. - Patient Interviews: Nurses gather information directly from patients through interviews to understand their symptoms, concerns, and medical history. - Physical Examinations: Data collected during physical examinations include vital signs, physical findings, and observational data. - Diagnostic Tests: Results from laboratory tests, imaging studies, and other diagnostic procedures contribute to the clinical data pool.
