NHS 111 online is a Class 1 medical device

Product details

NHS 111 online is a digital triage system available for members of the public in England. It uses clinical content from NHS Pathways to get people to the most appropriate level of care for their symptoms. 111 online does not give a diagnosis but advises users what to do next and in what timeframe based on their answers to the triage questions. You can read more detail about how the 111 online service works and about NHS Pathways.

111 online uses the Directory of Services (DoS) to refer patients to locally-commissioned services that best meet their needs.


Intended use

NHS 111 online is a web-based ‘unassisted’ triage system intended to be used for patients who are 5 years old and above. It assesses the symptoms presented at the time of use of the online tool. Symptoms can include injuries, illnesses, dental or mental health problems or any existing medical condition. 

Users are asked a series of questions in a specific order and then given the most appropriate clinical response based on the answers.

Life-threatening symptoms are assessed first, followed by less urgent symptoms requiring a less urgent response.

Use of the online tool is not intended for:

  • children under 5 years old
  • making treatment decisions following admission to hospital
  • predicting the expected outcomes of patients being treated
  • denying anyone care
  • automatically removing someone from a high risk group
