** 2020, Courtney J Pitts, Sexually Transmitted Infections, An Issue of Nursing Clinics, page 435:For MSM preferring event-based PrEP dosing, the nurse should counsel that this is an off-label use of the medication.
** 2020, World Health Organization, Consolidated HIV strategic information guidelines, page 90:If event-based dosing is recorded in patient records or service registers, efforts must be made to ensure the confidentiality and security of these records, since event-based dosing will identify these clients as men who have sex with men.
** 2024, Shannon C. Miller, Richard N. Rosenthal, Sharon Levy, The ASAM Principles of Addiction Medicine:TDF/FTC has also shown benefit when taken "on demand," or "event-based dosing,” operationalized as two pills on the day of potential exposure through sexual intercourse, and one pill daily up to 72 hours after the last potential exposure.
* (public health) Pertaining to exposure (to toxic substances, radiation, etc.) that results from a (usually accidental) event, as opposed to chronic or regularly-occurring exposure.
** 2001, Fluence-based and Microdosimetric Event-based Methods for Radiation Protection in Space, page 39:A chief advantage of the microdosimetric event-based approach is that one measures directly the energy deposition responsible for the carcinogenic effect and thus there is no need to know the kind of particle or the energy of the carcinogenic effect and thus there is no need to know the kind of particle or the energy of the particle that produced an energy deposition event.
** 2002, K. Asante-Duah, Public Health Risk Assessment for Human Exposure to Chemicals, page 109:Event-based intake values are converted to final intake values by multiplying the intake per event by the frequency of exposure events, over the timeframe being considered in an exposure assessment.
** 2020, Gerhard Heinemeyer, Matti Jantunen, Pertti Hakkinen, The Practice of Consumer Exposure Assessment, page 145:It would be almost impossible to estimate the exposure to a speccified substance on an event-based level, due to a lack of appropriate data and since the intakes and the concentration in the sources will show variation from event to event .
* Pertaining to training that involves simulated situations as opposed to drill in specific skills.
** 2000, Dorothy L. Finley, Combined Arms Structured Simulation-based Training Programs, page 39:It should not become what is known as "event-based training."
** 2004, Jennifer E.Fowlkes, C.Shawn Burke, “Event-Based. Approach. to. Training. (EBAT).”, in Neville Anthony Stanton, Alan Hedge, Karel Brookhuis, editor, Handbook of Human Factors and Ergonomics Methods, page 458:The event-based approach to training (EBAT) is used to guide the design of scenario- or simulation-based training.
** 2018, James Szalma, Peter A Hancock, Performance Under Stress, page 279:Moreover, there is another factor that differentiates stress exposure training from traditional training, and that is that stress exposure training is event-based.
