Alcohol Medical Intervention Clinic: A Rapid Access Addiction Medicine Model Reduces Emergency Department Visits.

OBJECTIVES: Problematic alcohol use accounts for a large proportion of Emergency Department (ED) visits and revisits. We developed the Alcohol Medical Intervention Clinic (AMIC), a Rapid Access Addiction Medicine (RAAM) service, to reduce alcohol-related ED re-utilization and improve care for individuals with alcohol problems. This article describes the AMIC model and reports on an evaluation of its impact on patients and the ED system. METHODS: Individuals presenting to The Ottawa Hospital Emergency Departments (TOH-ED) for an alcohol-related issue were referred to AMIC. Using data collected via medical chart review, and also self-report questionnaires, we assessed ED visits, revisits, and changes in alcohol use and mental health symptoms in patients before and after receiving services in AMIC. The incidence of alcohol-related ED visits and re-visits from 12-month periods before and after the introduction of AMIC were compared using data from TOH Data Warehouse. Connections made to additional services and patient satisfaction was also assessed. RESULTS: For patients served by AMIC, from May 26, 2016 to June 30, 2017 (n = 194), there was an 82% reduction in 30-day visits and re-visits (P < 0.001). An 8.1% reduction in total alcohol-related 30-day TOH-ED revisit rates and a 10% reduction in total alcohol-related TOH-ED visits were found. After receiving AMIC services, clients reported reductions in alcohol use, depression, and anxiety (P < 0.001). CONCLUSIONS: AMIC demonstrated positive impacts on patients and the healthcare system. AMIC reduced ED utilization, connected people with community services, and built system capacity to serve people with alcohol problems.

FPGA based demodulation of laser induced fluorescence in plasmas.

We present a field programmable gate array (FPGA)-based system that counts photons from laser-induced fluorescence (LIF) on a laboratory plasma. This is accomplished with FPGA-based up/down counters that demodulate the data, giving a background-subtracted LIF signal stream that is updated with a new point as each laser amplitude modulation cycle completes. We demonstrate using the FPGA to modulate a laser at 1 MHz and demodulate the resulting LIF data stream. This data stream is used to calculate an LIF-based measurement sampled at 1 MHz of a plasma ion fluctuation spectrum.
