Hospital records are broadly classified into four categories: patient clinical records, individual staff records, ward records, and administrative records. Common record forms include admission nursing history forms, flow sheets, graphic records, patient care summaries, standardized care plans, progress notes, and discharge summary forms. The most common documents in a patient's record are the admission sheet, physician's order sheet, nurse's admission assessment, graphic/flow sheets, medical history and examination, nurses' notes, medication records, progress notes, and diagnostic test results.
