COVID Oximetry @home - digital and data services

We’re delivering digital and data services for COVID Oximetry @home, a service to monitor patients with coronavirus (COVID-19) symptoms in their own home or care home.

Oximetry notice

In July 2022, NHS Digital started a managed closure of the COVID Oximetry @home data services it provides to clinical commissioning groups (CCGs). This was to align with the end of the COVID-19 COPI notices and to reduce data collection burden. The closure is now complete.

A national supply of pulse oximeters remains available by request to support COVID Oximetry @home services. 


COVID Oximetry @home involves the remote monitoring of patients with coronavirus symptoms. Patients use a pulse oximeter, a small monitor clipped to their finger, to measure their oxygen saturation levels three times a day.

They record their results using one of the following:

  • smartphone app
  • web portal
  • paper diary

The paper-based option is available at all sites for patients who are uncomfortable with or unable to use a digital solution to record their readings.

Patients are supported by clinical staff locally, so that if they need further treatment they can be admitted to hospital at the right time.

Benefits of the programme

We know patients with serious coronavirus symptoms often do not go to hospital early enough, and this can negatively impact patient outcomes.

Some patient groups more likely to present late include:

  • healthcare workers
  • BAME patients

For every day of delay in hospital admission the chance of death increases by 1%, observational data suggests.

Our role in national implementation

The COVID Oximetry @home programme is led by NHS England. NHS Digital’s primary role is to deliver Oximetry @home data and digital architecture, and to collect data for service utilisation.

Our role includes:

  • sending to Oximetry @home providers a daily list of patients in their area who have tested positive for coronavirus, with indicators included for those who meet the recommended eligibility criteria for Oximetry @home (aged 65+ and/or considered higher risk and/or are symptomatic at the point of testing). We also flag those patients who have not received two doses of COVID-19 vaccine, or the second dose was within the last 14 days
  • collecting data from Clinical Commissioning Groups (CCGs) weekly about patients onboarded and offboarded
  • disseminating data for evaluation and management information purposes
  • creating new SNOMED codes so that providers can code Oximetry @home activity accurately
  • updating NHS Pathways to enable COVID Oximetry @home patients to be identified and triaged effectively
  • updating NHS systems to make other services aware that a patient is being monitored by COVID Oximetry @home – this may include changes like adding a flag to the summary care record
  • standardising templates to be used in GP systems
  • supporting the integration of COVID Oximetry @home apps with other NHS systems

We have also undertaken discovery and research into user needs, including patients, NHS staff and the NHS nationally.

Information for providers of Oximetry @home

Data collection

We're collecting a dataset from clinical commissioning groups, on a weekly basis, using the Secure Data Collection Service (SDCS). This will be in the form of a weekly Situation Report (SitRep) and will be used capture service utilisation. 

We're asking for the least amount of data possible, to keep admin time for frontline staff to a minimum.

The collection includes information on:

  • number of patients onboarded to COVID Oximetry @home within the last submission period
  • total number of patients *(at the point of data submission) who are on the COVID Oximetry at home caseload

The information will be used to manage and evaluate the service.

*More information can be found in the SitRep webpage.
