 \n\nNear-Equivalent Q-learning Policies for Dynamic Treatment Regimes\n\nP
 recision medicine seeks to adapt treatments to individual patient profiles
  in order to deliver the right treatment to the right patient at the right
  time\, particularly in longitudinal settings with multiple decision point
 s. 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
