The electronic system, which allows patients to check in at a computer screen instead of waiting in line at a counter, is being trialled at Chorley and South Ribble Hospital and could be introduced at Royal Preston Hospital.

Hospital bosses hope the scheme will speed up the arrival of patients at reception.

The outpatients department at the hospital now has two touch screen computerised check-in facilities so patients can check themselves in.

Karen Partington, chief operating officer at Lancashire Teaching Hospitals NHS Foundation Trust, said: "This is an exciting development.

"People are more used to using this type of technology which is readily available at airports, railways stations and banks.

"Its introduction at Chorley and South Ribble Hospital will be a step forward and will reduce pressure on the outpatient reception area.

"We are always looking to innovate and provide an improved patient experience.

"This technology will be available to use by those who want to, while others can still book in to clinics at the traditional reception areas.

"Depending on the success of the trial, the trust may consider this application at Royal Preston Hospital."

However, union bosses are not so sure and say they will be looking at the results of the trial with interest.

A spokesman for Preston Unison said: "Unison will be looking at the trial very carefully to fully assess whether it is of real benefit to the patient experience or whether it is just cost-cutting.

"In today's computer driven world, do we truly need a further erosion of the 'personal touch' that is so essential to the delivery of a positive health care experience?"
