Data Talking to Machines: The Intersection of Deep Phenotyping and Artificial Intelligence

By Carmel Shachar

As digital phenotyping technology is developed and deployed, clinical teams will need to carefully consider when it is appropriate to leverage artificial intelligence or machine learning, versus when a more human touch is needed.

Digital phenotyping seeks to utilize the rivers of data we generate to better diagnose and treat medical conditions, especially mental health ones, such as bipolar disorder and schizophrenia. The amount of data potentially available, however, is at once both digital phenotyping’s greatest strength and a significant challenge.

For example, the average smartphone user spends 2.25 hours a day using the 60-90 apps that he or she has installed on their phone. Setting aside all other data streams, such as medical scans, how should clinicians sort through the data generated by smartphone use to arrive at something meaningful? When dealing with this quantity of data generated by each patient or research subject, how does the care team ensure that they do not miss important predictors of health?

Is Real-World Health Algorithm Review Worth the Hassle?

By Jenna Becker

The U.S. Food and Drug Administration (FDA) should not delay their plans to regulate clinical algorithms, despite challenges associated with reviewing the real-world performance of these products. 

The FDA Software Pre-Certification (Pre-Cert) Pilot Program was designed to provide “streamlined and efficient” regulatory oversight of Software as a Medical Device (SaMD) — software products that are regulable by the FDA as a medical device. The Pre-Cert program, in its pilot phase, is intended to inform the development of a future SaMD regulatory model.

Last month, the FDA released an update on Pre-Cert, highlighting lessons learned from pilot testing and next steps for developing the program. One key lesson learned was the difficulty in identifying and obtaining the real-world performance data needed to analyze the clinical effectiveness of SaMDs in practice. Although this challenge will be difficult to overcome in the near future, the FDA’s plans to regulate should not be slowed by insufficient postmarket data.
