Work under the supervision of a RN, the patient sitter maintains constant visual observation of the assigned patient, assists in ensuring a safe and clean environment, communicates patient activity and behavior regularly to the nurse, interacts professionally and respectfully with patients, families, and healthcare team members, and provides support to peers and staff. Sitters do not perform clinical procedures but play a vital role in patient safety and support, especially for patients with cognitive impairment, delirium, or high fall risk.
