Emerging uses of health data
Health data is increasingly being used to help drive better outcomes, including improving diagnosis, reducing health inequalities, increasing patient participation, saving money and resources, and driving innovation. Some real-world examples for each of these follow:
Health data to improve diagnosis
Big data analytics has the potential to transform healthcare by assisting the diagnosis of certain diseases and improving the management of chronic diseases.
In Boston, US, health data has been used in artificial intelligence systems to increase the accuracy and speed of identification of bacteria that is known to cause bloodstream infections.
Health data to reduce inequalities
Health data is being used across EU member states by integrating information systems to better address health inequalities, analyse health outcomes disaggregated by specific factors (socio-economic status, gender, ethnicity and education) and potentially reduce risk factor exposure of vulnerable groups.
In Brazil, data has been used to increase resource allocation, bringing more doctors to remote and low-income areas. When high rates of maternal mortality were seen during the COVID-19 pandemic, some states used this data to prioritise pregnant women for vaccinations, which is now a national policy.
Health data to encourage patient participation
The online research platform, PatientsLikeMe, allows patients with life-changing illnesses to share their experience using patient-reported outcomes. Responses to a survey from 1,323 participants (19% of the almost 7,000 members) showed that users perceived the greatest benefit as learning about their symptoms (72%) and rated the site as “moderately helpful” or “very helpful”. By enabling patients to make use of data about them, they were able to participate more actively in understanding their health and wellbeing.
Increasing the availability and sharing of data among stakeholders enabled greater patient participation in activities focused on reducing risks to eye health through the INSIGHT Health Data Hub.
Health data to save money
In Minneapolis, US, the use of health data and machine learning algorithms has saved the health system more than $60 million over five years, while also improving clinical outcomes for patients.
Working with publicly available prescription data in the UK, a data tech startup was able to identify potential savings of up to £200 million per year for the NHS in England.
Health data to drive innovation
Accelerating the use of data to enable artificial intelligence tools to make analyses has fostered new industry and public research partnerships in Ontario, Canada. These partnerships focus on developing new health technologies such as enhanced radiology, remote patient monitoring and early diagnosis of life-threatening illnesses in premature babies.
The availability of health data has enabled the development of international partnerships between public health researchers, pharmaceutical companies and Finnish health tech startups. These new collaborations are designing innovative health solutions, such as diagnostic tools and cancer treatments.
