Speech recognition with intuitive coding


With Lexacom Echo, you can enter text into any application live, you can instantly insert regularly used sections of text, and you can navigate and control applications.

Lexacom Echo can recognise complicated medical terms and define them for patients, to improve their understanding.

And now, Lexacom Echo can automatically code clinical information as you speak.

What is clinical coding?

Clinical coding is the process of translating medical terminology into a coded format. It allows accurate and consistent documentation of patient information such as diagnosis, medical treatment, procedures, and prescriptions.

Clinical coding allows organisations to search for patient information to identify groups that may require additional care. An example would be searching for patients with certain medical conditions or those on certain treatments that may make them clinically vulnerable and therefore require additional doses of the COVID vaccine.

The history of coding

The first nationally adopted system of coding was Read coding, developed in 1985 by Dr James Read. A Read code consisted of a letter and a number that uniquely identified a clinical term, for example H33.. is the Read code for asthma.

The Read coding hierarchy was retired in April 2020 to be replaced by SNOMED CT, which stands for Systematized Nomenclature of Medicine Clinical Terms. Each SNOMED CT code is a numerical code at least 6 digits long and gives a clinical term a unique concept identification. An example is the 271737000 concept ID for anaemia (disorder).

This system of coding works in conjunction with the World Health Organisation and their International Classification of Disease 11(ICD11).

Why coding is important

Having accurate and consistent clinical coding also helps organisations plan their care resources, for example by knowing how many people have arthritis affecting their hips they can plan how many hip replacements may be required, and how many orthopaedic surgeons may also be required.

Also, consistent clinical coding can help organisations such as the UK Health Security Agency identify early outbreaks of infections such as the recent outbreak of botulism in France.

Coding in primary care

Having accurate and consistent coding allows practices to identify populations of patients, as well as demonstrate completed work to the NHS.

Examples of such work include vaccinations, NHS health checks, cervical smears, Quality and Outcome Framework (QOF), and Investment and Impact Fund (IIF).

For subjective and objective observations codes are added automatically, for diagnostic and chronic disease monitoring, codes are manually triggered

Speech recognition with intuitive coding

Lexacom Echo is the only speech recognition software able to code clinical information as it is spoken.

This saves an incredible amount of time, and also improves the quality of data recorded about each patient.

Coding patient information correctly, rather than storing it as free text, standardises the data and allows for accurate planning across multi-disciplinary teams and PCNs.

Intuitive coding with Lexacom Echo speech recognition

Automatic coding is optional, and can be toggled on and off instantly to suit.
This can be any time you like; per patient, for each field in SystmOne, or even
activated for particular sentences.

Lexacom Echo understands the SOAP (subjective, objective, assessment, plan)
method of documenting patient consultations:

  • For observations that are subjective and objective, codes are added automatically as you speak, for example saying “Patient drinks x units of alcohol per week”  will automatically code in SystmOne: “Alcohol units per week (Ub173) 8 Units/Week”
  • However diagnostic and chronic disease monitoring codes must be manually triggered by saying “SNOMED…”  beforehand, for example “SNOMED type one diabetes”  or “SNOMED epilepsy medication review”.


Coding is included in our 2.8 update for users with SystmOne. For users with EMIS Web and Vision, coding will be included in our next update.
