NHS Undercover: Channel 4’s Dispatches programme claims that the NHS 111 service, including services provided by Harmoni from centres in Bristol and Dorking, leave patients waiting for calls and is understaffed.
But the programme doesn’t show a representative picture of how the NHS 111 service actually works or how it is performing, how quickly it responds to patients with a diverse range of needs or how it affects other urgent health care services.
Remember that the NHS 111 service is not an emergency service and doesn’t replace the 999 service.
Harmoni has given Channel 4 and Dispatches a detailed response to the concerns the programme broadcast, many of which were based on third hand comments and anecdotes, gathered over only a handful of days, without checking how the service was actually performing."
