Digital medicine, or just medicine

Digital medicine, on its way to being just plain medicine

You may remember at the begining of this century. Everybody was talking about e-business and right now nobody talks about it, because it is just business.The same will happen with digital medicine, it ill be just medicine in the next future. A future that is closer than you may think. And this is what E. topol explains in the editorial of the new open journal, and says_
And finally, quite paradoxically, we hope that npj Digital Medicine is so successful that in the coming years there will no longer be a need for this journal, or any journal specifically focused on digital medicine.
I agree. But meanwhile, somebody should review current syllabus and studies of medicine, to introduce a change in the profession and the scope of practice.

Spending a lot for many years: understanding persistence

Long-Term Health Spending Persistence among the Privately Insured in the US

If you don't want to read this article, check this presentation. It is one of the best efforts to understand persistence of health expenditures. Summarised findings:
First, persistence by demographic characteristics is generally lower than persistence by co-morbidities. Because co-morbidities are harder to assess, particularly for new enrollees, than demographics, this highlights the need for robust risk prediction models. 
Second, people with a co-morbid condition relative to those without the condition are considerably more likely to be in the top 10 per cent of spenders in year t regardless of whether they were in the top 10 per cent in year t–1. However, people with a co-morbid condition are even more likely to be in the top 10 per cent in year t if they were also in the top 10 per cent in year t–1.
Third, those most likely to be in and remain in the top 10 per cent are those with myocardial infarction, congestive heart failure and peptic ulcer disease and in several psychiatric diagnostic groupings, which indicates that these conditions might be appropriate targets for longer-term disease management programmes.
Fourth, although most conditions are less common at younger ages, when they do occur they are more predictive ofpersistently high spending at younger ages, as almost all conditions have the highest predicted probabilities on being in the top 10 per cent of spenders in the following year when they occur at ages under 25 and the lowest predicted probabilities when they occur in the 65-and-over population. Essentially, the presence of a condition at a younger age more clearly differentiates a person’s health care trajectory from that of their peers.
These are conclusions for US population, closer studies are needed.

How morbidity explains health expenditures in ageing

Ageing and healthcare expenditures: Exploring the role of individual health status

Everybody admits that ageing increases health expenditures. However the dynamics of this growth, and the factors that contribute it, are less known. In our recent article, we explain why morbidity is the main factor that explains growth of health expenditures in ageing. In our analysis, closeness to death is not the main cause.
Regardless of the specific group of healthcare services, HCE at the end of life depends mainly on the individual health status. Proximity to death, sex, and marginally age approximate individual morbidity when it is excluded from the model. The inclusion of morbidity generally improves the goodness of fit. These results provide implications for the analysis of ageing population and its impact on HCE that should be taken into account.
We do need further research on the cost and intensity of care in the last months of life, and this is our next challenge.
