Learning to Ask Like a Physician: a Discharge Summary Clinical Questions (DiSCQ) Dataset

Eric Lehman

Dataset of questions asked by medical experts about patients. Medical experts will read a discharge summary line-by-line and (1) ask any question that they may have and (2) record what in the text "triggered" them to ask their question.

Announcing the MIMIC-IV Waveforms

News from: MIMIC-IV Waveform Database v0.1.0.

Aug. 9, 2022

We are pleased to announce an initial release of a version (0.1.0) of the MIMIC-IV-Waveform module. These waveforms are a rich source of patient information - including ECG, PPG, and Blood Pressure signals - and can be linked to the clinical information in MIMIC-IV. This initial release contains 200 records from 198 patients. An upcoming release will include around 10,000 records.

The dataset was the subject of a workshop at IEEE EMBC in July of 2022, led by Peter Charlton, which demonstrated how to use the WFDB-Python package to extract and analyze waveform features. Executable notebooks and tutorial materials are available at: https://mimic.mit.edu/docs/iv/tutorials/waveform/ieee_workshop/ .

Rethinking Algorithm Performance Metrics for Artificial Intelligence in Diagnostic Medicine

July 29, 2022

Gari Clifford and Matthew Reyna from Emory University and Elaine Nsoesie from Boston University recently published an invited viewpoint in The Journal of the American Medical Association on "Rethinking Algorithm Performance Metrics for Artificial Intelligence in Diagnostic Medicine". The viewpoint focuses on how we often use the wrong optimization targets when applying machine learning to medical data, and how we can address this issue, and is part of the Gordon and Betty Moore Foundation's broader series on Diagnostic Excellence.

Our servers at MIT are undergoing and testing and maintenance work between Friday 15th and Monday 18th July 2022. PhysioNet (https://physionet.org/) will remain active during this period, but some services may be affected (for example, the archive website https://archive.physionet.org/).

Trust Markers with ORCID

June 30, 2022

Linking an ORCID to your PhysioNet profile can help us to quickly verify your identity, speeding up the process of gaining access to datasets such as MIMIC.

When reviewing an ORCID profile, we look out for “Trust Markers” which are pieces of information added to the profile by groups such publishers and employers.

To find out more about how PhysioNet is working with ORCID, see their blog post on how we are using the Trust Markers to streamline the data credentialing process.

Significant delays are expected to applications for credentialed access to PhysioNet.

April 7, 2022

We are currently dealing with a high volume of applications for credentialed access to PhysioNet, so please expect significant delays (up to 45 days) in the review process. We are doing our best to deal with the waitlist quickly, handling applications in the order in which they are received. To help ensure that your application is successful, please remember to:

Include a copy of your CITI training report (not the certificate).
Remind your reference to reply promptly when contacted.
Check your application details are correct before submitting.
Add an institutional or educational email address as your primary email.

We apologize for the inconvenience. Please bear with us during this busy time!
