Sepsis is a life-threatening condition that occurs when the body's response to infection causes tissue damage, organ failure, or death (Singer et al., 2016). In the U.S., nearly 1.7 million people develop sepsis and 270,000 people die from sepsis each year; over one third of people who die in U.S. hospitals have sepsis (CDC). Internationally, an estimated 30 million people develop sepsis and 6 million people die from sepsis each year; an estimated 4.2 million newborns and children are affected (WHO). Sepsis costs U.S. hospitals more than any other health condition at $24 billion (13% of U.S. healthcare expenses) a year, and a majority of these costs are for sepsis patients that were not diagnosed at admission (Paoli et al., 2018). Sepsis costs are even greater globally with the developing world at most risk. Altogether, sepsis is a major public health issue responsible for significant morbidity, mortality, and healthcare expenses.
Early detection and antibiotic treatment of sepsis are critical for improving sepsis outcomes, where each hour of delayed treatment has been associated with roughly an 4-8% increase in mortality (Kumar et al., 2006; Seymour et al., 2017). To help address this problem, clinicians have proposed new definitions for sepsis (Singer et al., 2016), but the fundamental need to detect and treat sepsis early still remains, and basic questions about the limits of early detection remain unanswered. The PhysioNet/Computing in Cardiology Challenge 2019 provides an opportunity to address these questions.
Data used in the competition is sourced from ICU patients in three separate hospital systems. Data from two hospital systems will be publicly available; however, one data set will be censored and used for scoring. The data for each patient will be contained within a single pipe-delimited text file. Each file will have the same header and each row will represent a single hour's worth of data. Available patient co-variates consist of Demographics, Vital Signs, and Laboratory values, which are defined in the tables below.
The following time points are defined for each patient:
- 1. Clinical suspicion of infection identified as the earlier timestamp of IV antibiotics and blood cultures within a specified duration.
- 2. If antibiotics were given first, then the cultures must have been obtained within 24 hours. If cultures were obtained first, then antibiotic must have been subsequently ordered within 72 hours.
- 3. Antibiotics must have been administered for at least 72 consecutive hours to be considered.
- The occurrence of end organ damage as identified by a two-point deterioration in SOFA score within a 24-hour period.
- The onset time of sepsis is the earlier of and as long as occurs no more than 24 hours before or 12 hours after ; otherwise, the patient is not marked as a sepsis patient. Specifically, if , then .

Objective of the Challenge
The goal of this Challenge is the early detection of sepsis using physiological data. For the purpose of the Challenge, we define sepsis according to the Sepsis-3 guidelines, i.e., a two-point change in the patient's Sequential Organ Failure Assessment (SOFA) score and clinical suspicion of infection (as defined by the ordering of blood cultures or IV antibiotics) (Singer et al., 2016).
The early prediction of sepsis is potentially life-saving, and we challenge participants to predict sepsis 6 hours before the clinical prediction of sepsis. Conversely, the late prediction of sepsis is potentially life-threatening, and predicting sepsis in non-sepsis patients (or predicting sepsis very early in sepsis patients) consumes limited hospital resources. For the challenge, we designed a utility function that rewards early predictions and penalizes late predictions as well as false alarms.
We ask participants to design and implement a working, open-source algorithm that can, based only on the clinical data provided, automatically identify a patient's risk of sepsis and make a positive or negative prediction of sepsis for every time interval. The winners of the Challenge will be the team whose algorithm gives predictions with the highest utility score for the patients in the hidden test set.
Accessing the Data
- Click here to download the complete training database (42 MB), consisting of two parts: training set A (20,336 subjects) and B (20,000 subjects).
The Challenge data repository contains one file per subject (e.g.,
training/p00101.psv for the training data).
Each training data file provides a table with measurements over time. Each column of the table provides a sequence of measurements over time (e.g., heart rate over several hours), where the header of the column describes the measurement. Each row of the table provides a collection of measurements at the same time (e.g., heart rate and oxygen level at the same time). The table is formatted in the following way:
HR |O2Sat|Temp|...|HospAdmTime|ICULOS|SepsisLabel NaN| NaN| NaN|...| -50| 1| 0 86| 98| NaN|...| -50| 2| 0 75| NaN| NaN|...| -50| 3| 1 99| 100|35.5|...| -50| 4| 1
There are 40 time-dependent variables
HospAdmTime, which are described here.
The final column,
SepsisLabel, indicates the onset of sepsis according to the Sepsis-3 definition, where
1 indicates sepsis and
0 indicates no sepsis. Entries of
NaN (not a number) indicate that there was no recorded measurement of a variable at the time interval.
Note: spaces were added to this example to improve readability. They will not be present in the data files.
Submitting Your Entry
Entries should be submitted through the new cloud submission system for the official phase of the Challenge. Please see here for detailed instructions.
Given a table of clinical measurements (columns) over time (rows), your entry must report the risk of sepsis (a real number) and a binary sepsis prediction (0 or 1) at each hour of a patient’s clinical record using the current and past (but not future) data for the patient (see the "Accessing the Data" section). Please note that we have shifted the sepsis labels in the training data ahead by six hours (see the "Challenge Data" section), so we are effectively asking participants to predict sepsis six hours early. We will repeat this process for k = 1, 2, …, N hours, where N is the number of hours in a given patient's recording, and for each patient in the test set. Please see the sample prediction and evaluation code" for details.
Your final algorithm will be graded for its binary classification performance using a utility function that we created for the Challenge. This utility function rewards classifiers for early predictions of sepsis and penalizes them for late/missed predictions and for predictions of sepsis in non-sepsis patients.
We first define a score for each prediction, i.e., for each patient and each time interval (each line in the data file):
The following figure illustrates the utility function for a sepsis patient (upper plot) with = 48 as an example and a non-sepsis patient (lower plot):
This utility function rewards or penalizes classifiers using their predictions on each patient:
- For patients that eventually have sepsis (i.e., with at least one
SepsisLabelentry of 1), we reward classifiers that predict sepsis between 12 hours before and 3 hours after , where the maximum reward is a parameter (1.0). We penalize classifiers that do not predict sepsis or predict sepsis more than 12 hours before , where the maximum penalty for very early detection is a parameter (0.05) and the maximum penalty for late detection is also a parameter (-2.0).
- For patients that do not eventually have sepsis (i.e., all
SepsisLabelentries of 0), we penalize classifiers that predict sepsis, where the maximum penalty for false alarms is a parameter (0.05; equal to the very early detection penalty). We neither reward nor penalize those that do not predict sepsis.
We then compute a score for a classifier by summing over each prediction, i.e., over each patient and each time interval (each line in the data file):
To improve interpretability, we normalized the above classifier score so that the optimal classifier (highest possible score) receives a normalized score of 1 and that a completely inactive classifier (no positive predictions) receives a normalized score of 0:
Each classifier receives a score, and the classifier with the highest score wins.
A Python implementation of the scoring metric is available here.
A simple example algorithm is provided and may be used as a template for your own submission. MATLAB ( here), Python (here), and R ( here) implementations are available.
Rules and Deadlines
Entrants may have an overall total of up to 15 submitted entries over both the unofficial and official phases of the competition (see Table 2).
All deadlines occur at 11:59pm GMT (UTC) on the dates mentioned below. If you do not know the difference between GMT and your local time, find out what it is before the deadline!
|Unofficial Phase||6 February||5||14 April|
|[Hiatus]||15 April||0||21 April|
|Official Phase||22 April||10||25 August|
All official entries must be received no later than 11:59pm GMT on 25 August. In the interest of fairness to all participants, late entries will not be accepted or scored. Entries that cannot be scored (because of missing components, improper formatting, or excessive run time) are not counted against the entry limits.
To be eligible for the open-source award, you must do all of the following:
- Entering an Abstract to CinC: Submit an acceptable abstract (about 300 words) on your work on the Challenge to Computing in Cardiology no later than 15 April. Include the overall score for your Phase I entry in your abstract. Please select “PhysioNet/CinC Challenge” as the topic of your abstract, so it can be identified easily by the abstract review committee. You will be notified if your abstract has been accepted by email from CinC during the first week in June.
- Submit at least one open-source entry that can be scored during the second phase (between 12:01am GMT on 22 April and 11:59pm GMT on 25 August). Only your final entry will count for ranking.
- Submit a full (4-page) paper on your work on the Challenge to CinC no later than the deadline of conference paper submission.
- Attend CinC 2019 (8-11 September 2019) in Singapore and present your work there.
Please do not submit analysis of this year’s Challenge data to other Conferences or Journals until after CinC 2019 has taken place, so the competitors are able to discuss the results in a single forum. We expect a special issue from a journal to follow the conference and encourage all entrants (and those who missed the opportunity to compete or attend CinC 2019) to submit extended analysis and articles to that issue, taking into account the publications and discussions at CinC 2019.Non open source licenses
Software with non open-source licenses will be scored but not ranked in the official competition. All scores will be made public. At the end of the competition, all software will be posted publicly, and therefore, automatically mirrored on several sites around the world. We have no control over these sites so cannot remove code even on request. Before the end of the competition your code is not publicly available and you can choose to withdraw from this event up until the closing date of the competition in August.
However, there is one caveat for all non open source code: The organizers reserve the right to retain and use a copy of the code for non-commercial use. This allows us to re-score if definitions change, and validate any claims made by competitors.Rules on competing in teams / collaboration
To maintain scientific impact of the Challenges, it is important that all Challengers enter truly independent ideas. For this reason we impose the following rules on team composition/collaboration:
- Multiple teams from a single entity (such as a company, university or even university department) are permissible as long as the teams are truly independent, and do not share team members (at any point), code or any ideas. (Multiple teams from the same research group or unit within a company are not allowed because we do not believe true independence between teams can be maintained in circumstances where members can talk to each other face-to-face while at work / in a break room.)
- New team members can join as long as they have not previously been in another team that year, or have communicated with a team member from any other team at any point during the competition concerning this year's Challenge.
- You may use public code from another team if they posted it before the competition.
- You may not post your code publicly during the competition, or use other competitor's code posted during the competition, whether it was intentional or not.
- You may not publicly post information describing your methods (blog, code, preprint, magazine article, vlog, presentation, talk etc) or give a talk outside your own research group at any point during the competition that reveals the methods you have employed or will employ in the Challenge. Obviously you can talk and publish on the same methods on other data as long as you don't indicate that you have also used it on the challenge data.
- You must use the same team name and email address throughout the course of the competition, and the email address should be the same as the one used to submit your abstract to Computing in Cardiology. (Note that the submitter of the conference article/code does not have to be the presenter at the conference, or in any particular location in the author order on the abstract/poster/paper, but they must be a member of the team.) If your team has used multiple team names and/or email addresses top enter the Challenge, please contact the organizers immediately to avoid potential disqualification.
If evidence of the contravention of these rules are discovered, you will be ineligible for a prize and your entry publicly marked as possibly associated with another entry. Although we will contact the team(s) in question, time and resources are limited and the Organizers must use their best judgement on the matter in a short period of time. The Organizer's decision on this will be final.
Submitting an Abstract to the Conference
First, please think about your title very carefully. There are going to be over 100 abstracts with very similar titles, so your title must reflect the details of what you actually did. (Don't worry about the issue of your methods evolving over the competition, and making your title somewhat inappropriate - you can update it when you submit your final paper in early September.) If you use a vague title, it decreases the chances your abstract will be accepted and the organizers may modify it for the program to allow conference attendees to decide if the poster or talk will be of interest to them. For instance, 'Machine Learning for Predicting X' or 'Signal Processing Methods for Detection of Y' are not useful titles. Also, please do not use the terms 'PhysioNet', 'Challenge' or 'Computing in Cardiology' in the title. There will be an article in the proceedings which carries the same name as the competition (the title of this web page). Using any of these terms is likely to cause significant confusion when searching for the definitive article describing the Challenge and results. Please note, when you submit to the abstract submission system please choose the track 'Physionet/CinC Challenge' to ensure it is reviewed by the Challenge organizers.
Please ensure you describe your exact approach in the abstract, detailing novelty and specific pre/post-processing steps that made a difference in your performance. DO NOT rationalize or describe the competition and the data - this is a waste of valuable space (you only have 300 words). Your abstract is intended as preliminary evidence that you will attend the conference and have meaningfully contributed to the unofficial phase. If you have not been successful in receiving a score from our scoring system, don't worry. Report cross validated scores on the available public data we have posted and your methods in detail. Do not describe the challenge. It's a waste of valuable words - the reviewers know what the Challenge is this year. We also know your results and your methods will change. Your final abstract (which will accompany the preprint you post to the conference in early September before the conference begins) will be very different. The point of the abstract is to decide if you have an original idea, promising/logical approaches and can express these coherently. It helps us allocate limited oral presentations and poster space to the best entries. [If you do get rejected, there may be a 'wild card' chance to enter later on in the Challenge, but if we able to do this, it will be for an exceptional entry, so please don't rely on this.]
Abstract Acceptances/Rejections: You should receive an acceptance or rejection notice by the end of May, although sometimes this is later. Some reviews will contain comments, but generally there is only a score. Although we try to include everyone, it is not possible given the limited space at the conference venue, so please take the abstract seriously. If you do not receive an email with the decision by the end of May (on the email address with which you registered for the conference), please check your spam filter. If you still can't find one, email challenge [AT] physionet.org to obtain confirmation of the abstract acceptance/rejection. Please do not email any of the organizers directly (for any reason) - there's a good chance the email will go astray. If you email challenge [AT] physionet.org, the Challenge team will triage your email and try to address your issues. You may receive and email from the organizers indicating that we've modified your title slightly. This is to avoid confusion between abstracts that have vague or non-specific titles, and in particular mentioned the phrases 'Computing in Cardiology', 'Challenge' or PhysioNet'. You may modify this later to correct any misconceptions this may cause, or to update the content based on your evolving algorithm, but please do not re-insert the prohibited words/phrases or make the title generic once again. Your final paper will be rejection and you will be de-ranked from the leader board (since publishing a paper in the conference proceedings is part of the requirements of the competition).
Wild Card Submission
If you failed to have your abstract accepted, or did not enter an abstract and submission in time for the deadline, you have a chance to become the 'wild card' entry. The top scoring entry on the leader board by the end of the day (midnight GMT) on June 20th, not already with an email acceptance from the conference, will have the chance to submit an abstract for inclusion in the program and be eligible for the final prizes with everyone else. If you think you qualify, please email challenge [at] physionet.org by 12 *noon* GMT June 21st for confirmation, and your updated abstract by might night GMT June 22nd.
There will be an on-site Hackathon revisiting the Challenge (with a separate award) on Sunday 8th September, before the conference begins in Singapore. Any team with at least one attendee at the conference, who turns up in person to register, is eligible to enter. You do not have to have entered the Challenge or have an abstract in the conference before this date. Moreover, you may combine forces with other teams to produce hybrid algorithms. We suggest you peruse the conference preprints in the first week of September to find potential partners. This part of the Challenge is organized and sponsored by MathWorks and Google Cloud, so there will be hands-on help, although you are not required to use Google Cloud or Matlab for developing and entry (although we use Google Cloud to run the results). The rules and restrictions are otherwise the same.
Attending the Conference
If your abstract is accepted, then you must log in to the conference site and agree that you will attend. You must also submit a full article describing your results and mark it as a preprint (for others to read) by 4 September. (Don't forget that the competition deadline is noon GMT on 25 August - this deadline will not be extended.)
More details about the conference will follow.
Look out for future announcements via the community discussion forum.
After the Challenge
We hope to run a special issue with a closing date of (to be decided). We will therefore encourage competitors (and non-competitors) to submit updates and further reworks based on the Challenge after the award ceremony at the Computing in Cardiology Conference in Singapore in September.
Obtaining complimentary MATLAB licenses
MathWorks has generously decided to sponsor this Challenge by providing complimentary licenses to all teams that wish to use MATLAB. Users can apply for a license and learn more about MATLAB support by visiting the PhysioNet Challenge page from MathWorks. If you have questions or need technical support, then please contact MathWorks at email@example.com.
Google has generously agreed to provide $50,000 in Google Cloud Platform (GCP) credits for this Challenge. We will award these to the 100 top performing teams, probably in May (at a date yet to be determined). This will hopefully provide an added incentive to submit more entries earlier on, and give teams the maximum opportunity to learn before spending money in the cloud.
At the time of launching this Challenge, Google Cloud offers multiple services for free on a one-year trial basis and $300 in cloud credits. See here for more information. Additionally, if teams are based at an educational institution in selected countries, they can access free GCP training online here.
Google Cloud credits of $500 per team will be made available to teams with both a successful entry to the official phase of the Challenge and an accepted abstract to CinC. Only one credit of exactly $500 will be provided to one email address associated with each team. The Challenge organizers, their employers, and Computing in Cardiology accept no responsibility for the loss of credits, or failure to issue credits for any reason. By providing us with this information, you are granting us permission to forward your details to Google for the distribution of credits. Please complete this form to request credits by May 29th. You will have until June 1st to redeem the credits and they will be valid for 90 days.
Pre-conference Challenge Hackathon
This year, for the first time, we are introducing a final opportunity to win a prize in the Challenge. On the Sunday morning before Computing in Cardiology starts, there will be an all-day hackathon (with on-site support from 9am-1pm local time) in Singapore, with the same objective as the current Challenge. This event is, once again, generously sponsored by the Gordon and Betty Moore Foundation, MathWorks and Google.
Most of the same rules apply, but you may form a new team for this event or even merge with an existing team. You do not need to have previously competed in the Challenge, but you must register for the event at least 4 days in advance, listing all of your hackathon team members (known at the time - you may add or remove some later, but we will be watching to check for adherence to the rules).
Please complete this form for the PhysioNet/CinC 2019 Hackathon.
Note: At least one member of each hackathon team must be physically present and register for the conference as well as the hackathon. If these details are missing from the above form, you will not be allowed to participate.
Space is limited and will be allocated on a first-come, first-served basis. If there is room, you may be able to register with less than 4 days to the event, or even on the same day as the event, but you will encounter delays at the entrance to the event, where security will check you against the registration list we sent 4 days earlier.
Please note, the event is not at the same as any other conference event, but is nearby.
Location of Hackathon: 1 Fusionopolis Way, #14 Connexis South, Singapore 138632
Date and time: Sunday, 8 September 2019 from 9:00 AM to 1:00 PM local time.
Refreshments and technical support will be available (and maybe some more cloud credits!) ...
The deadline for submitting code will be later on Sunday (exact time to be announced). Please make sure the rest of your team (who are not present) are aware of the time zone difference with their local times. You may collaborate with them remotely all day to prepare and submit your code. Due to space restrictions, a maximum on site team size of 4 is allowed. There is no limit on the team size for remote members.
You may ask: why a hackathon?
- Well this is no ordinary hackathon. You will have had up to 7 months to prepare for it, so we expect it to generate some novel ideas.
- You may collaborate with other teams from the Challenge or other teams that turn up (but only submit one entry per collaboration), thus potentially generating new and better hybrid approaches.
- On-site support for Google Cloud and Matlab and domain experts in clinical informatics will be present.
