Predictive prevention and the drive for precision public health
The idea of precision medicine has been outlined as a set of prevention and remedy methods that take particular person variability under consideration. The intention is to supply the fitting remedy to the fitting affected person on the proper time on the grounds that this may each enhance outcomes for sufferers and make the entire system extra environment friendly.
The strategy clearly has implications for public well being and the time period precision public health has inevitably been coined to explain the appliance of this pondering to inhabitants well being.
Approaches to precision public well being
One model of precision public well being is all about sorting folks into extra exact teams based on their danger for widespread circumstances, reminiscent of heart problems (CVD) or most cancers. New risk scores for CVD are actually showing based mostly on whole-genome affiliation research from very massive cohorts reminiscent of UK Biobank, and these seem to carry out higher than current scores. Nonetheless, the brand new polygenic danger scores are usually not but routinely accessible and documenting danger is barely of worth if that danger can then subsequently be mitigated. We don’t but know if these scores can be utilized to enhance outcomes.
Critics of this type of precision public well being level out that many determinants of well being don’t function on the stage of people and that issues reminiscent of air air pollution or social inequalities require interventions on the stage of entire communities and even nationally. That mentioned, we all know that early analysis is the important thing to higher outcomes in lots of cancers. It might appear extremely seemingly that higher understanding of determinants of particular person danger will result in simpler prevention in the long term.
A second extra expansive model of precision public well being is about using information and analytical methods to design and implement interventions that profit entire populations. This model emphasises using subtle surveillance and modelling and has been promoted by the Invoice and Melinda Gates Basis. It’s actually interesting and is typified for instance by the latest Global Burden of Disease study and far of PHE’s work on an infection management and well being enchancment.
The period of precision public well being is upon us and all of us must turn into accustomed to the ideas. As well as (because the Topol evaluation on the way forward for the healthcare workforce is prone to report subsequent yr) the general public well being workforce, like others within the well being sector, must upskill within the areas of information science and digital supply as these are the shiny new instruments within the precision public well being toolbox.
Predictive prevention within the context of precision public well being
The Secretary of State for Well being & Social Care, Matt Hancock, outlined a particular instance of precision public well being in his latest speech – Prevention is Higher than Treatment – which promoted PHE’s work on predictive prevention. This includes the cautious, focused and consensual use of information to supply digitally-enabled well being enchancment interventions in a means persons are almost definitely to interact with and act on.
Such a digital engagement is a complicated and unobtrusive strategy that’s extensively and successfully utilized in different sectors to attach folks with the companies and merchandise they’re almost definitely to need and wish. It’s solely pure to contemplate how this know-how could be harnessed in public well being. It matches very effectively with the final pattern in public well being as we benefit from higher information and scientific proof to be extra exact and environment friendly in every thing we do.
Predictive prevention doesn’t change current public well being interventions at inhabitants or group stage – however it does construct on current data-driven focusing on methods and channels so as to add one other dimension of deeper buyer engagement. By persevering with to mix behavioural science and digital improvements, we are able to actively encourage folks to make more healthy selections and take higher accountability for his or her wellbeing.
Greedy the chance
PHE will deliver collectively a variety of consultants to construct, consider and mannequin completely different approaches to predictive prevention at scale.
A totally digital public well being system may higher anticipate the general public’s wants, and supply personalised instruments to assist folks reside more healthy for longer.
While digital interventions is not going to be a panacea, by constructing on the prevailing experience within the UK and the proof we’ve seen from different nations, we see digital taking part in a vital position in bringing revolutionary adjustments to how persons are supported to reside more healthy lives.
Predictive prevention will play a significant half in constructing this, utilizing our current methods of selling higher selections and higher well being – but in addition driving additional innovation as know-how develops.
Utilizing personas to design tailor-made digital interventions
One of the best ways to design for everyone is to achieve a deep understanding of individuals – the precise customers of our digital companies. We will then exactly tailor our providing, utilizing instruments and codecs that meet folks’s wants, work with their motivations and assist overcome their challenges.
A technique of articulating these insights is thru ‘personas’ – consumer profiles which describe the attributes of the teams they symbolize, together with their social and demographic traits, motivations, habits and cultural backgrounds.
The interventions we design utilizing personas could also be delivered by digital platforms, apps, or a wearable gadget like a sensible watch – however by understanding folks on this means, we are able to make sure that we at all times use the very best strategy for our customers’ wants. Some examples are beneath:
Serving to folks in actual time
Since turning into unemployed twelve months in the past, David spends most of his time, when not on the lookout for work, taking part in pc video games and on social media. He self identifies as having points with sleep and chooses to share display time and sleep information with our digital service that helps folks handle their sleep situation. This information, appropriately safeguarded, is used to supply self-help digital instruments on how David can, on a typical late night time, handle the ideas racing by his thoughts.
Utilizing textual content messaging for pressing recommendation
Sharmi is a journalist and has simply returned to the UK from an space in Africa the place malaria is endemic. As quickly as she pulls up from the airport within the taxi, she will get a textual content reminding her of the significance of ending the complete course of her antimalarial remedy.

This extra data helps his GP make choices about use of statins or antihypertensive medication. Predictive analytics are then used to supply tailor-made recommendation and steering on different way of life adjustments Ron may make.
Utilizing social media to information folks to prevention companies

These are associated to her cardiovascular well being, however she’s additionally invited to contemplate different related interventions, like Sort 2 diabetes prevention.
