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.
State laws may require a health care provider keep a patient's medical records for a certain period of time. Under PA law, a doctor must keep a patient's medical record for at least 7 years after the last treatment date. The exception is for the medical records of a minor, those records must be kept until 1 year after the minor reaches the age of majority or for 7 years, whichever is longer. Similarly, hospitals must keep medical records for at least 7 years after a patient is discharged from the hospital. Hospital records of minors must be kept until age of majority plus 7 years. In practice, many health care providers keep their medical records longer. And for as long as those records are kept, a patient has a right to see them.
