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.

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
