UK has best health system in developed world, US analysis concludes | The BMJ

The UK’s healthcare system is the best out of 11 of the world’s most developed countries, despite having one of the lowest levels of funding.The US health think tank the Commonwealth Fund ranked the UK number one, closely followed by Australia, then the Netherlands, New Zealand, Norway, Switzerland, Sweden, Germany, Canada, France, and the US.1 This is the second time in a row that the UK has come at the top of the ranking, carried out every three years.2The US came last, despite spending by far the most on health: 16.6% of its gross domestic product, nearly double that spent by Australia, at 9% the smallest proportion among the 11 countries, and the UK, at 9.9%. The US spent more …

Flexible Analysis of Electronic Medical Record Data with Composite Mixture Models | bioRxiv

The widespread adoption of electronic medical records (EMRs) in healthcare has provided vast new amounts of data for statistical machine learning researchers in their efforts to model and predict patient health status, potentially enabling novel advances in treatment. However, there are significant barriers that must be overcome to extract these insights from EMR data. First, EMR datasets consist of both static and dynamic observations of discrete and continuous-valued variables, many of which may be missing, precluding the application of standard multivariate analysis techniques. Second, clinical populations observed via EMRs and relevant to the study and management of debilitating conditions like sepsis are often heterogeneous; properly accounting for this heterogeneity is critical. Here, we describe a joint probabilistic framework called a composite mixture model that can simultaneously accommodate the wide variety of observations frequently observed in EMR datasets, stratify heterogeneous clinical populations into relevant subgroups, and handle missing observations. We demonstrate the efficacy of our approach by applying our framework to a large-scale sepsis cohort, identifying physiological trends and distinct subgroups of the dataset associated with elevated risk of mortality during hospitalization.

Distributions are becoming irrelevant: difference was our strength and our liability

For someone that has spent the past thirteen years defining himself as a developer of a Linux distribution (whether I really am still a Gentoo Linux developer or not is up for debate I’m sure), having to write a title like this is obviously hard. But from the day I started working on open source software to now I have grown a lot, and I have realized I have been wrong about many things in the past.
