DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SFUOR/9/">In
 dividualized Dynamic Patient Monitoring Under Alarm Fatigue</a>\nby Hossei
 n Piri (University of Calgary) as part of PIMS-CORDS SFU Operations Resear
 ch Seminar\n\nLecture held in ASB 10908.\n\nAbstract\nHospitals are rife w
 ith alarms\, many of which are false. This leads to $alarm$ $fatigue$\, 
 in which clinicians become desensitized and may inadvertently ignore real 
 threats. We develop a partially observable Markov decision process model f
 or recommending dynamic\, patient-specific alarms in which we incorporate 
 a $cry$-$wolf$ feedback loop of repeated false alarms. Our model takes in
 to account patient heterogeneity in safety limits for vital signs and lear
 ns a patient’s safety limits by performing Bayesian updates during a pat
 ient’s hospital stay. We develop structural results of the optimal polic
 y and perform a numerical case study based on clinical data from an intens
 ive care unit. We find that compared with current approaches of setting pa
 tients’ alarms\, our dynamic patient-centered model significantly reduce
 s the risk of patient harm.\n
