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 should records be kept? Although states may have different guidelines or laws, The Doctors Company recommends the following: Adult patients, 10 years from the date the patient was last seen. Minor patients, 28 years from the patient's birth. Deceased patients, five years from the date of death. In California, where there is no statutory requirement regarding physician offices, the California Medical Association recommends that medical records be retained indefinitely or for at least 25 years after the patient's last visit.
