Tsunami warning system. A tsunami warning system (TWS) is used to detect tsunamis in advance and issue warnings to prevent loss of life and damage. It is made up of two equally important components: a network of sensors to detect tsunamis and a communications infrastructure to issue timely alarms to permit evacuation of the coastal areas.
The law also requires nursing facilities to maintain medical records for each patient. The records must be kept for seven years after the patient is discharged from the facility. If the patient is a minor, the records must be kept for one year after the patient reaches the age of 18, but for at least seven years.
Tennessee healthcare facilities are required to keep medical records as originals or reproductions for 10 years following discharge or death of the patient. In cases involving minors or patients with mental disabilities, the hospital must keep records for the period of disability or minority plus one year, or 10 years following discharge of the patient, whichever is longer.
