The affidavit, medical record, documents, and forms referred to in this Act may be in hard copy or electronic format. Nothing in this Act is intended to prevent the population of an affidavit, medical record, document, or form with electronic data. A living will, mental health treatment preferences declaration, practitioner orders for life-sustaining treatment (POLST), or power of attorney for health care that is populated with electronic data is operative. Electronic documents under this Act may be created, signed, or revoked electronically using a generic, technology-neutral system in which each user is assigned a unique identifier that is securely maintained and in a manner that meets the regulatory requirements for a digital or electronic signature. Compliance with the standards defined in the Uniform Electronic Transactions Act or the implementing rules of the Hospital Licensing Act for medical record entry authentication for author validation of the documentation, content accuracy, and completeness meets this standard.
