An investigation has been launched into the opening hours of antiviral collection points in Lincolnshire.

Health Secretary Andy Burnham said he would review the accessibility of Tamiflu in the county after it was revealed the reduced opening times at some centres were inadequate.

The situation came to light when a listener told BBC Radio Lincolnshire that they had to wait 23 hours before an antiviral collection point was open.

Talking to BBC Radio Lincolnshire Health Secretary Andy Burnham said: "I can't give a precise example in that particular case.

"What we have said is that, right around the country we want primary care trusts to have accessible places that are open for a good deal of time during the day."

North Hykeham Health Centre, the nearest collection point for the majority of people in Lincoln and North Hykeham closed at 3pm on Sunday, August 9 and did not reopen until 2pm on Monday.

When the issue of people diagnosed on Sunday having to wait nearly a day before having access to Tamiflu Mr Burnham said: "I can't really give a comment here and now but I would have expected people in that situation to have access to antivirals first thing on Monday morning.

NHS Lincolnshire said the recently reduced opening times, which were updated on the NHS website on August 6, were because fewer people were coming to collect the antiviral medication because of a decrease in referrals.

Dr Mandy Bretman, Director of Public Health and Partnerships said: "Lincolnshire Antiviral Collection Points (ACPs) were planned in accordance with the national guidance from the Department of Health.

"The size and geography of the county pose challenges and we need to balance this service without disrupting our services to other patients."
