A computer which monitors the health of people with long term medical conditions from their homes is being rolled out in North Yorkshire.
NHS North Yorkshire and York said it was investing £3.2m in 2,000 of the Telehealth systems.
The units monitor the patients' vital signs, including blood pressure, blood glucose and oxygen levels.
Any abnormalities are seen by staff at a control centre who will contact the patient's GP or nurse if necessary.
NHS North Yorkshire and York said the decision to install the units was made following positive feedback after 60 were trialled in the county.
The main purpose of the computer is to identify and act on any deterioration in a patient's condition before they need to be admitted to hospital.
David Cockayne, director of strategy for NHS North Yorkshire and York, said: "We are delighted to announce this significant investment in Telehealth which we and local clinicians believe will continue to make a huge difference for patients living with a long term heath conditions."
Patients suffering from heart failure and diabetes are among those who will benefit, the trust said.
Pauline Waite, 56, from Acomb, who suffers from emphysema, said it was reassuring to know her condition was being monitored while she retained her independence.
"I'm sure that many other patients can benefit from Telehealth just like I have and live a happier and much more comfortable lifestyle," she said.
