Race, substance use, and evaluation for heart transplantation: Insights from a large urban medical center.

It is unknown whether racial disparities in access to heart transplantation (HT) are amplified when coupled with substance use. We examined patients evaluated for HT over 8 years at an urban transplant center. We evaluated substance use and race/ethnicity as independent and interactive predictors of HT and left ventricular assist device (LVAD) implantation.

Augmented Intelligence to Identify Patients With Advanced Heart Failure in an Integrated Health System.

Background: Timely referral for specialist evaluation in patients with advanced heart failure (HF) is a Class 1 recommendation. However, the transition from stage C HF to advanced or stage D HF often goes undetected in routine care, resulting in delayed referral and higher mortality rates.

Objectives: The authors sought to develop an augmented intelligence-enabled workflow using machine learning to identify patients with stage D HF and streamline referral.

An Automated Toolchain for Camera-Enabled Sensing of Drinking Water Chlorine Residual.

Chlorine residual concentration is an important parameter to prevent pathogen growth in drinking water. Disposable color changing test strips that measure chlorine in tap water are commercially available to the public; however, the color changes are difficult to read by eye, and the data are not captured for water service providers. Here we present an automated toolchain designed to process digital images of free chlorine residual test strips taken with mobile phone cameras.
