TheResearchQuestion
Toexaminewhichpatient- andcontext-relatedfactorsimpacttheantidepressantefficacyofexerciseintherealclinicalworld,amongelderlypatientssufferingfrommajordepression
WhattheResearchersDid• SEEDSstudycomparedtheantidepressantefficacyofsertralineplusphysicalexercise(24weeks,3timesperweek)vs.sertralinealone.
• Setting: consultationliaisonprogramforprimary care
• post-hocanalysis:identifiedfactorspredictedhigherchancesofremissionintheexperimentalgroup;contextualfactorsandPCPsopinionswerealsoexplored
WhattheResearchersFound• Ideal candidate toreceive sertralineplusexercise:patientwhoisolderthan75,hasretainedagoodaerobicfitness,displayspsychomotorretardationbut notsevereanxiety
• Longstandingconsultationliaisonprogramisimportantfortherecruitmentandfollowupofpatients:PCPsexpressedveryfavorableviews re: addingexercise asanantidepressant
WhatThisMeansforClinicalPractice
• Olderpatientswithmajordepressioncanbesafelyandeffectivelytreatedwithacombinationofstructuredphysicalexerciseandantidepressantdrugs.
• ThefeasibilityofthisinterventiondependsonthelevelofcollaborationbetweenPCPsandotherspecialists.Moreover,theeffectivenessagainstdepressionisparticularlyhighamongselectedpatients.

TheResearchQuestion1. Calculatetheproportionofstrokes/TIAs with
priormissedopportunitiesforprevention2. Determineiftheproportionofmissed
opportunitieshaschangedovertime3. Investigatetheassociationwithpatientor
demographic characteristics
WhattheResearchersDidRetrospectiveanalysisofanonymised,electronicUKprimarycarerecords
Population• First-stroke/TIA• ≥18years• 2009-2013
OutcomesAnticoagulant,
Antihypertensive orLipidLoweringdrugsNOT prescribedwhenclinicallyindicated
Analysis• %ofpatientswith
missedpreventionopportunities
• Logisticregression
WhattheResearchersFound%Missedopportunities:• Anypreventiondrug:54%(9,579/17,680)– Anticoagulants:52% (1,647/3,194)– Lipidloweringdrugs:49% (7,836/16,028)– Antihypertensives: 25% (1,740/7,008)
Changeovertime(2009-2013)• Onlyanticoagulantdrugprescribingimproved

TheResearchQuestion

Doesmaximumdailydoseofprescriptionopioiduseleadtonewonsetdepressionwhencontrollingfordurationofuse,painandotherconfounders?
WhattheResearchersDid• Retrospectivecohortdesign from:
– VeteransAdministration(VA),n=70,997– BaylorScott&White(BSW),n=13,777– HenryFordHealthSystem(HFHS),n=22,981
• VariablescreatedfromICD-9-CMcodes,pharmacyrecords,vitalsigns,labresultsetc.
• SeparateCoxmodelscomputedtoestimateassociationbetweenopioidduration,morphineequivalentdoseandnewdiagnosisofdepression
WhattheResearchersFound
• Riskofnewonsetdepressionincreasedwithopioiddurationineachpatientsample.>90dayusewasassociatedwith35%to105%increasedriskofnewonsetdepressioncomparedto1-30 day use.
• Dosewasnotassociatedwithnewonsetdepression
WhatThisMeans forClinical Practice
• Baseline depression screening insufficient, consider depression screening at each opioid refill
• Add depression to risk:benefit discussion• Short term euphoria but long term depression• Opioid taper if new onset depression in
chronic pain• Consider opioid, not just pain, as source of
depression
