Patient’s dismay at being thrown out of GP practice

…

The West Road Surgery declined to comment.

Andrew Stride, head of governance, risk and customer services for NHS South Essex, said: “We would advise all patients who have concerns about any aspect of local NHS care to contact the Patient Advice and Liaison Service on 0800 5879159 for help and advice.

“While we are unable to comment on individual cases, we would like to assure patients there is a procedure GP practices need to follow before they can remove patients from their lists.”
