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.
How long is a physical therapist required to retain medical records? The patient records must be maintained for at least seven years following the discharge, except the records of unemancipated minors must be maintained for at least one year after the minor reaches the age of 18. How long does a physical therapist have to send me the copy of medical records I requested? If you made your request in writing for the records to be sent directly to you, the physical therapist must provide copies to you within 15 days. The physical therapist can charge a reasonable fee for the cost of making the copies.
