Channel modeling and characterization for VLC-based medical body sensor networks: trends and challenges
Optical Wireless Communication (OWC) refers to transmission in unguided propagation media through the use of optical carriers, i.e., visible, Infrared (IR), and Ultraviolet (UV) bands. In this paper, we focus on indoor Visible Light Communication (VLC)-based Medical Body Sensor Networks (MBSNs) which allow the Light Emitting Diodes (LEDs) to communicate between on-body sensors/subdermal implants and on-body central hubs/monitoring devices while also serving as a luminaire. Since the Quality-of-Service (QoS) of the communication systems depends heavily on realistic channel modeling and characterization, this paper aims at presenting an up-to-date survey of works on channel modeling activities for MBSNs. The first part reviews existing IR-based MBSNs channel models based on which VLC channel models are derived. The second part of this review provides details on existing VLC-based MBSNs channel models according to the mobility of the MBSNs on the patient’s body. We also present a realistic channel modeling approach called site-specific ray tracing that considers the skin tissue for the MBSNs channel modeling for realistic hospital scenarios.Scientific Research Projects (BAP) (Grant Number: 20A204)Publisher's Versio

PERCEPTIONS AND EXPERIENCES OF ADOPTING A TECHNOLOGY BASED INTERVENTION FOR ALCOHOL SCREENING AND REFERRAL TO TREATMENT IN PRIMARY CARE
Alcohol abuse is a significant concern in the United States. Today in the U.S., 15.1 million adults ages 18 and older, have been identified as having an alcohol use disorder. Alcohol abuse and binge drinking are highest amongst college students. More than 58.0 percent of college students admit to regular binge drinking or heavy alcohol use every month. Left unaddressed, this leads to negative health consequences later in life. The United States Preventive Services Task Force states that there is strong evidence that screening patients in primary care can reduce alcohol use disorder. Though screening, brief intervention, and referral to treatment (SBIRT) in primary care are critical steps towards preventing alcohol use disorder, it is not routinely done. Providers state that they are time-constrained and need processes that will help them carry out screenings. The use of technology integrated with the electronic health record is one way to address the issue. The purpose of this study was to provide an understanding of the health care provider\u27s perceptions and experiences with technology adoption in alcohol use disorder and clinical SBIRT. The study used an exploratory, descriptive methods approach to gain a comprehensive understanding of what acts as a facilitator or barrier to technology adoption in SBIRT in primary care. The findings show that there is a gap in the understanding of how to integrate behavioral health screenings in the primary care workflow and EHR. Providers want to do SBIRT in clinical care, yet time-constrained visits remain an issue. Providers highlighted the importance of mapping the workflow in advance of practice change and using pilots before undertaking a broader practice change
