Symposium - Keynote talk: Prescription trajectories computed from data on 7.2 million patients

HeaDS has just announced the SUND Symposium on Health Data Science! The symposium will bring together researchers to discuss developments and cutting-edge research in the field of health data science. The goal of the symposium is to highlight developments in different areas of health data science research, to inspire new ideas and to open up an opportunity for networking and collaboration.


The symposium will open with a keynote speech on “Prescription trajectories computed from data on 7.2 million patients (1.1 billion prescriptions)” by Professor Søren Brunak (Novo Nordisk Foundation Center for Protein Research).


Søren and his team recently published "Optimizing drug selection from a prescription trajectory of one patient", where they used 24 years of data (1.1 billion prescriptions) from the Danish prescription registry to model the risk of sequentially redeeming a drug after another. Drug pairs were used to build multistep longitudinal prescription trajectories.

These were subsequently used to stratify patients and calculate survival hazard ratios between the stratified groups. The similarity between prescription histories was used to determine individuals’ best treatment options. Over the course of 122 million person-years of observation, we identified 9 million common prescription trajectories and demonstrated their predictive power using hypertension as a case. This is an exciting study showing that prescription trajectories can provide novel insights into how individuals’ drug use changes over time, identify suboptimal or futile prescriptions and suggest initial treatments different from first-line therapies. Observations of this kind may also be important when updating treatment guidelines


At the symposium, there will be a range of exciting talks by invited speakers, followed by a poster session in which researchers from various data science-related groups at SUND present their work. Afterwards, we look forward to networking and socializing over refreshments and snacks.


Date: 29 November 2021.

Time: 10:00 - 16:00.

Place: Old Faculty Club at SUND (room 16.6.16), Panum. Blegdamsvej 3B, 2200 Copenhagen.
