The Associate to Patient button is used to assign the attachments under the Attachments node to a specific patient record. To associate the attachment to a patient, click the Associate To Patient button. From the resulting window, select a patient. The file will be moved from the Attachments node to the Patient Attachments node.
If a file is associated to the wrong patient, move the file to another patient by clicking the disclosure triangle next to the patient name, or by Control-clicking on the file and selecting Change Patient from the Options menu. Select the patient in the resulting window. The file will be moved to the Patient Attachments node of the correct patient.
