PICTURE: Adult General Floor Deterioration Prediction

  PICTURE is a suite of machine learning algorithms that utilizes electronic health record (EHR) data to predict patient deterioration in hospital settings. This iteration is modeled specifically for adult inpatients in a hospital general floor. 

Value Proposition

Early detection of patient deterioration has been found to lead to reduced mortality risk, reduced length-of-stay and decreased hospital costs, yet identifying patient deterioration is a challenge for clinicians. PICTURE’s Adult General Floor Analytic is a combination of machine learning algorithms utilizing electronic health record (EHR) data to passively and accurately predict ICU transfer or death as a proxy for patient deterioration. PICTURE also provides explanations for every single prediction, adding transparency to the model and how it calculated its output. This transparency is invaluable to clinicians who can use these explanations to guide decisions around patient care.

Competitive Advantage

PICTURE identifies a patient’s risk of deterioration beyond easily observable symptoms
PICTURE analytics predict deterioration an average of 30 hours in advance of the event, giving clinicians time to act
The PICTURE suite helps hospitals maintain a high level of patient care and distribute tightly-stretched resources efficiently

Unique Features

Provides an explanation of the main factors contributing to its prediction in each instance
Uses data that is collected during routine medical care such as common lab values
Will not disrupt clinician workflows or practices, even if policy changes alter routine tests
Defined thresholds allow each hospital unit to specify their desired precision
Designed to model patient’s physiology as opposed to clinician behavior, ensuring the alarms provide novel information to care providers
Adult model-specific: Code Blue Events and Mechanical Ventilation transfers are evaluated as target outcomes (in addition to death and ICU transfers)
Adult model-specific: Reference Range Normalization included for lab values

These products have completed extensive research and development and are actively seeking licensing partners to take them to market.

MARKET OPPORTUNITY
On average, PICTURE provides 30 hours advanced warning time and 17% fewer false alarms for every true alarm compared to the EPIC Deterioration Index when tested on COVID-19 patients. The PICTURE suite is part of a family of specialized data science tools available to be licensed from the Weil Institute.

Weil is also open to discussions of new research utilizing the technology developed for the PICTURE platform.
