About Definition health

Definition Health was founded to tackle the ever-growing importance of a digital future in healthcare and support the NHS’s long-term plan of digitisation and the net zero commitment.

Definition Health provides an end-to-end approach to digital patient services by digitising the entire patient journey into one cohesive experience. Via the LifeBox platform, patients can access all stages of their hospital journey from one account, including customisable health questionnaires, personalised educational media, file sharing and post-operative recovery monitoring.

An independent study by Unity Insights, working in partnership with Royal Surrey NHS Foundation Trust extrapolated to the Surrey Heartlands ICS, showed savings of £1.94 million per 43,000 patients over 5 years and a ROI of £1.50 for every £1 invested (50%). Per 12,000 patients over 5 years, 103 tCO2e could be saved in travel and 5 tCO2e in paper. A pilot study showed that only 17 (14.2%) of 120 hip replacement patients needed follow-up by a consultant surgeon following use of LifeBox, creating vital time and resource efficiencies.

“It empowers patients and engages them more fully in their own care, educating them about their surgical procedure and facilitating smooth admission. It also allows us to improve the standardisation of patient care and reduce unnecessary hospital visits.”
