The idea of precision medicine has been outlined as a set of prevention and remedy methods that take particular person variability into consideration. The intention is to supply the proper remedy to the proper affected person at the proper time on the grounds that this can each enhance outcomes for sufferers and make the entire system extra environment friendly.
The strategy clearly has implications for public health and the time period precision public health has inevitably been coined to explain the software of this considering to inhabitants health.
Approaches to precision public health
One model of precision public health is all about sorting individuals into extra exact teams in response to their threat for widespread situations, resembling heart problems (CVD) or most cancers. New risk scores for CVD at the moment are showing primarily based on whole-genome affiliation research from very giant cohorts resembling UK Biobank, and these seem to carry out higher than current scores. However, the new polygenic threat scores should not but routinely accessible and documenting threat is barely of worth if that threat 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 health level out that many determinants of health don’t function at the stage of people and that issues resembling air air pollution or social inequalities require interventions at the stage of entire communities and even nationally. That stated, we all know that early analysis is the key to higher outcomes in lots of cancers. It would appear extremely doubtless that higher understanding of determinants of particular person threat will result in simpler prevention in the long term.
A second extra expansive model of precision public health is about the use of information and analytical strategies to design and implement interventions that profit entire populations. This model emphasises the use of refined surveillance and modelling and has been promoted by the Bill and Melinda Gates Foundation. It is actually interesting and is typified for instance by the latest Global Burden of Disease study and a lot of PHE’s work on an infection management and health enchancment.
The period of precision public health is upon us and all of us must develop into conversant in the ideas. In addition (as the Topol assessment on the way forward for the healthcare workforce is prone to report subsequent 12 months) the public health workforce, like others in the health sector, must upskill in the areas of information science and digital supply as these are the shiny new instruments in the precision public health toolbox.
Predictive prevention in the context of precision public health
The Secretary of State for Health & Social Care, Matt Hancock, outlined a selected instance of precision public health in his latest speech – Prevention is Better than Cure – which promoted PHE’s work on predictive prevention. This includes the cautious, focused and consensual use of information to supply digitally-enabled health enchancment interventions in a means persons are most probably to interact with and act on.
This sort of digital engagement is a complicated and unobtrusive strategy that’s extensively and successfully utilized in different sectors to attach individuals with the companies and merchandise they’re most probably to need and want. It’s solely pure to think about how this expertise could be harnessed in public health. It matches very nicely with the normal development in public health as we benefit from higher information and scientific proof to be extra exact and environment friendly in all the things we do.
Predictive prevention doesn’t change current public health interventions at inhabitants or group stage – however it does construct on current data-driven focusing on strategies and channels so as to add one other dimension of deeper buyer engagement. By persevering with to mix behavioural science and digital improvements, we will actively encourage individuals to make more healthy decisions and take higher duty for their wellbeing.
Grasping the alternative
PHE will convey collectively a spread of consultants to construct, consider and mannequin totally different approaches to predictive prevention at scale.
A totally digital public health system may higher anticipate the public’s wants, and present personalised instruments to assist individuals stay more healthy for longer.
Whilst digital interventions won’t be a panacea, by constructing on the current experience in the UK and the proof we’ve seen from different nations, we see digital enjoying an important function in bringing revolutionary adjustments to how persons are supported to stay more healthy lives.
Predictive prevention will play a serious half in constructing this, utilizing our current methods of selling higher decisions and higher health – but in addition driving additional innovation as expertise develops.
Using personas to design tailor-made digital interventions
The finest strategy to design for all people is to achieve a deep understanding of individuals – the precise customers of our digital companies. We can then exactly tailor our providing, utilizing instruments and codecs that meet individuals’s wants, work with their motivations and assist overcome their challenges.
One means of articulating these insights is thru ‘personas’ – person profiles which describe the attributes of the teams they signify, together with their social and demographic traits, motivations, habits and cultural backgrounds.
The interventions we design utilizing personas could also be delivered by means of digital platforms, apps, or a wearable system like a wise watch – however by understanding individuals on this means, we will ensure that we all the time use the finest strategy for our customers’ wants. Some examples are under:
Helping individuals in actual time
Since turning into unemployed twelve months in the past, David spends most of his time, when not wanting for work, enjoying laptop 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 individuals handle their sleep situation. This information, appropriately safeguarded, is used to supply self-help digital instruments on how David can, on a typical late evening, handle the ideas racing by means of his thoughts.
Using 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 in the taxi, she will get a textual content reminding her of the significance of ending the full course of her antimalarial remedy. She is initially aggravated at the reminder however when she will’t discover her tablets in her suitcase, she pops to the nearest travel clinic to select up extra tablets so she will end her course.

It is embedded into his day by day schedule and helps him to trace his private progress. With applicable safeguarding and consent, it integrates personally generated information into his GP’s data. This extra data helps his GP make selections about use of statins or antihypertensive medication. Predictive analytics are then used to supply tailor-made recommendation and steerage on different life-style adjustments Ron may make.
Using social media to information individuals to prevention companies
Jess, from Liverpool, is a 47-year-old workforce chief in a excessive road store and is susceptible to creating CVD. Jess has been engaged to affix a prevention programme by means of a direct message she obtained on social media following a marketing campaign. She is inspired to document and add her personal information previous to her appointment – together with bodily exercise information, top and weight, smoking and alcohol use, and stress ranges.
She attends a health examine at a pharmacy on the excessive road the place she works. Using the information she has offered, Jess is directed to a spread of efficient interventions. These are associated to her cardiovascular health, however she’s additionally invited to think about different related interventions, like Type 2 diabetes prevention.
