Progress notes are written records used by healthcare professionals to document a patient's treatment and progress over time. These notes typically include information about the patient's condition, treatment plans, and any changes observed during each visit. They help ensure continuity of care and provide a clear history for other providers involved in the patient's care. These notes are essential for maintaining accurate records in settings like hospitals, clinics, and mental health facilities. They can also be used for billing purposes and to communicate important information among the healthcare team, ensuring everyone is informed about the patient's status and needs.
