Dynamic Treatment Regimes provide a formal framework to model treatment as a sequence of adaptive decisions evolving with the patient’s clinical trajectory. In this talk\, we focus on Near-Equivalent Q-learning Policies \, an extension of standard Q-learning that moves beyond the identificatio n of a single “optimal” strategy. Instead\, the method characterizes a set of statistically near-optimal treatment policies that achieve comparable expected outcomes. This allows treatment decisions to remain data-driven w hile supporting clinically flexible strategies\, where multiple valid opti ons can coexist and be adapted to practical constraints.\n\nTrends in the Prescription of Central Nervous System Depressants in Patients with Chroni c Obstructive Pulmonary Disease in the United Kingdom Primary Care\, 2000 – 2022\n\nPrescribing patterns of central nervous system (CNS) depressants have evolved in recent years\, but trends in patients with chronic obstru ctive pulmonary disease (COPD) remain unknown. Assessing these trends is e ssential given the potential risk of respiratory depression and other adve rse respiratory events in this population. Thus\, we examined time trends in the prescription of CNS depressants among patients with COPD in UK prim ary care from 2000 to 2022.\n\nSpeaker Bios\n\nSophia Yazzourh: For more i nformation please visit: https://sophiayazzourh.github.io/\n \n Omotayo Olao ye: For more information\, please visit: https://www.linkedin.com/in/omota yo-olaoye/ \n DTSTART:20260218T203000Z DTEND:20260218T213000Z SUMMARY:Near-Equivalent Q-learning Policies for Dynamic Treatment Regimes / Trends in the Prescription of Central Nervous System Depressants in Patie nts with Chronic Obstructive Pulmonary Disease in the United Kingdom Prima ry Care\, 2000 – 2022 URL:/epi-biostat-occh/channels/event/near-equivalent-q -learning-policies-dynamic-treatment-regimes-trends-prescription-central-n ervous-371228 END:VEVENT END:VCALENDAR
