Of the four components of P4 healthcare, participatory care is conceivably the most mature at this time. Personalised health, synonymous with "precision health" is about clustering and stratification of diseases and patients based on genomic networks and molecular signatures. However,  a limited set of tools for a few disease conditions are currently available, although the list will continue to grow (citations??). Flores et.al. (xxx) have argued that accuracy of predictions based on analyses of genomic networks and integrating them with clinical parameters is limited by the fact that existing predictions on who will develop diseases and/or complications are based on more parameters to estimate than the number of participants available to do the analyses; as a result, it is highly likely that the predictive algorithms are not quite ready to be applied in a general practice setting (cite Flores). Consequently, the predictive algorithms & preventive actions that follow on from the predictive algorithms are still not "mature" or "practice ready". Besides, these depend on the availability and fine tuning of information fed to this pipeline by data analysed upstream, and will in turn will grow with the user base.
