    CDC Guideline for Prescribing Opioids for Chronic Pain—

    United States, 2016

    Deborah Dowell, MD,MPH; TamaraM. Haegerich, PhD;Roger Chou, MD

    IMPORTANCE  Primary care clinicians find managing chronic pain challenging. Evidence of 

    long-term efficacy of opioids forchronic pain is limited. Opioiduse is associated with serious

    risks, including opioid use disorder and overdose.

    OBJECTIVE  To provide recommendations aboutopioid prescribing for primary care clinicians

    treating adultpatients with chronic pain outside of active cancer treatment, palliative care,

    and end-of-life care.

    PROCESS The Centers for Disease Control and Prevention (CDC) updated a 2014 systematic

    review on effectiveness andrisks of opioids andconducted a supplementalreview on

    benefits andharms, values andpreferences, andcosts. CDCused theGrading of 

    Recommendations Assessment, Development, and Evaluation (GRADE) framework to assess

    evidence type and determine the recommendationcategory.

    EVIDENCE SYNTHESIS  Evidence consisted of observational studies or randomized clinical trials

    with notable limitations, characterized as low quality using GRADE methodology.

    Meta-analysis wasnot attempted due to thelimited number of studies,variabilityin study

    designs and clinical heterogeneity, and methodological shortcomings of studies. No study

    evaluated long-term (1 year) benefit of opioids forchronic pain. Opioids were associated

    with increased risks, including opioid use disorder, overdose, and death, with

    dose-dependent effects.

    RECOMMENDATIONS   There are 12 recommendations. Of primary importance, nonopioid

    therapy is preferred for treatment of chronic pain. Opioids should be used only when benefits

    for pain and function are expected to outweigh risks.Before starting opioids, clinicians should

    establishtreatment goals with patients andconsider how opioids will be discontinued if benefits do notoutweigh risks. When opioids areused, clinicians should prescribe the lowest

    effective dosage, carefully reassess benefits and risks when considering increasing dosage to

    50 morphine milligram equivalentsor more per day, and avoidconcurrent opioids and

    benzodiazepines whenever possible. Clinicians should evaluate benefits and harmsof 

    continued opioidtherapy with patients every 3 monthsor more frequently andreview

    prescription drug monitoring program data, when available, for high-risk combinations or

    dosages. For patients with opioid use disorder, clinicians should offer or arrange

    evidence-based treatment, such as medication-assisted treatment with buprenorphine or

    methadone.

    CONCLUSIONS AND RELEVANCE   The guideline is intended to improve communicationabout

    benefits andrisks of opioids forchronic pain, improve safety and effectiveness of pain

    treatment, and reduce risks associated with long-term opioid therapy.

    The number ofpeople experiencing chronicpain is substan-

    tial, with US prevalence estimated at 11.2% of the adult

    population.1Patientsshouldreceiveappropriatepaintreat-

    ment based on a careful consideration of the benefits and risks of

    ducted to rigorously assess the long-term benefits of opioids for

    chronic pain (pain lasting >3 months) with outcomes examined at

    least 1 yearlater.7Opioid painmedication usepresentsserious risks.

    From 1999 to 2014, more than 165 000 persons died of overdose

    relatedtoopioidpainmedicationintheUnitedStates. 8 In2013alone,

    an estimated 1.9 millionpersonsabusedor weredependenton pre-

    scription opioidpain medication.9Primarycarecliniciansreportcon-

    cern aboutopioid pain medication misuse, find managingpatients

    with chronic pain stressful, express concern about patient addic-

    tion, and report insufficient training in prescribingopioids.10

    The “CDC Guideline for Prescribing Opioids for Chronic Pain—

    United States,2016,” is intended forprimary careclinicians (eg, fam-

    ily physicians, internists, nurse practitioners, and physician assis-

    tants)whoaretreatingpatientswithchronicpain(ie,painconditions

    that typicallylast>3 months or past thetime of normal tissueheal-

    ing)in outpatientsettings. Theguideline is intendedto applyto pa-

    tients18 years andolderwith chronic pain outside of activecancer

    treatment,palliative care,and end-of-life care.Some of the recom-

    mendations might be relevantfor acute care settings or other spe-

    cialists,such as emergencyphysicians or dentists,but use in these

    settings or by other specialists is notthe focus of the guideline.

    Theguideline is intendedto improve communicationbetween

    cliniciansand patients about therisksand benefitsof opioid therapy

    forchronicpain, improve thesafetyand effectivenessof paintreat-

    ment,andreducetherisksassociatedwithlong-termopioidtherapy,including opioid use disorder, overdose, and death. Clinical deci-

    sion making should be based on a relationship between the clini-

    cian and patient andan understanding of thepatient’sclinicalsitu-

    ation, functioning, and life context. The recommendations in the

    guidelineare voluntary,rather thanprescriptive standards. Theyare

    basedon emergingevidence,including observationalstudies or ran-

    more extensive guideline; the full guideline with detailed informa-

    tionon disclosures and conflict of interest protocols, methods,sci-entificfindings,and recommendationrationalescanbe found in the

    Morbidity and Mortality Weekly Report (MMWR).11

    Guideline Development Process

    Grading of Recommendations Assessment, Development,

    and Evaluation Method

    CDCused theCDC Advisory Committee on ImmunizationPractices

    (ACIP) translation12 of the Grading of Recommendations Assess-

    ment, Development, and Evaluation (GRADE) method for guide-

    line development.13 Within the ACIP GRADE framework, the qual-

    ityofabodyofevidencewasgraded,andtherecommendationswere

    developedand placedinto categories (A or B) based onthe qualityof evidence, balance of benefits and harms, values and prefer-

    ences, and resource allocation (Box 1).

    CDCobtainedinputfrom experts,stakeholders,the public,peer

    reviewers,and a federallychartered advisory committee in the de-

    velopmentprocess.CDC drafted a set of recommendations and in-

    vited subject matterexperts,primarycare professionalsocietyrep-

    resentatives,and state agency representatives (Core Expert Group,

    listed atthe endof thearticle)to provideindividual perspectives on

    howCDC usedthe evidenceto developthe recommendations. CDC

    asked experts toundergo a rigorous process toassess andmanage

    possible conflicts of interest; full details on protocols and disclo-

    suresarereportedintheMMWR.11CDCalsoengagedpartnersfrom

    10 federal agencies and a Stakeholder Review Group of 18 organi-zations (listed at the end of the article) to provide comment. CDC

    convened a constituent engagement webinar to obtain additional

    perspectivesfrom constituents on thekey recommendations.Toob-

    taincomments fromthe publicon thefull guideline,CDC published

    anoticeinthe Federal Register (80 FR 77351) announcing theavail-

    ability of theguidelineandthe supporting clinical andcontextualevi-

    dence reviews for publiccomment. Per the final informationqual-

    ity bulletin for peer review (https://www.whitehouse.gov/sites

    Box1. Interpretation of Recommendation Categories

    and Evidence Type

    Recommendation Categories

    Recommendation categories are basedon evidence type, balance

    between desirable and undesirable effects,values and

    preferences,and resourceallocation (cost).

    Category A recommendation: Applies to all persons;mostpatients should receive the recommended course of action.

    Category B recommendation: Individual decision making needed;

    differentchoiceswill be appropriate for different patients.

    Clinicianshelp patients arrive at a decision consistent withpatient

    values and preferences and specific clinical situations.

    Evidence Type

    Evidencetypeis based onstudydesign as well as a functionof 

    limitationsin studydesign or implementation,imprecision of 

    estimates,variability in findings, indirectness of evidence,

    publicationbias, magnitudeof treatmenteffects, dose-response

    gradient, and constellationof plausible biasesthat could

    change effects.

    Type 1 evidence: Randomized clinical trialsor overwhelming

    evidence fromobservational studies.

    Type 2 evidence: Randomized clinical trials with important

    limitationsor exceptionallystrongevidencefrom observational

    studies.

    Type 3 evidence: Observational studies or randomized clinical

    trialswith notable limitations.

    Type 4 evidence: Clinical experience and observations,

    observational studies withimportantlimitations, or randomized

    clinical trialswith several majorlimitations.

    information. In addition, the National Center for Injury Prevention

    andControlBoardof ScientificCounselors(BSC),a federal advisory

    committee, established an Opioid Guideline Workgroup (OGW) to

    reviewtheguideline(membersoftheBSCandOGWarelistedatthe

    endof the article).The OGWissued a reportof observations to the

    BSC.At an in-personmeeting, theBSC consideredthe OGWreport,

    deliberated on the draft guideline itself, and offered an additional

    opportunity for public comment. The BSC voted unanimously tosupport the observations made by the OGW; that CDC adopt the

    guideline recommendations that, according to the workgroup’s

    report, had unanimous or majority support; and that CDC further

    consider the guideline recommendations for which the group had

    mixed opinions. At each stage, CDC reviewed and carefully

    considered comments and revised the guideline.

    Clinical Evidence Review

    To inform the guideline development process, CDC updated a sys-

    tematicreviewsponsoredbytheAgencyforHealthcareResearchand

    Quality (AHRQ) on the effectiveness and risks of long-term opioid

    treatmentofchronicpain7 thataddressedclinicalquestionsaboutef-

    fectiveness of long-term opioid therapy for outcomes at least 1 year

    later relatedto pain,function,andquality oflife.Theeffectiveness of short-term opioid therapy has been established previously. In ran-

    domized clinical trials 12 weeks or shorter in duration, opioids were

    moderatelyeffectiveforpainrelief,with smallbenefitsfor functional

    outcomes; although estimates varied, based on uncontrolled stud-

    ies,a high percentageof patients discontinued long-termopioid use

    because of lack of efficacy and because of adverseevents.3 Opioids

    have uniqueeffects such astoleranceand physical dependencethat

    mightinfluenceassessmentsofbenefitovertime.Theseeffectsraise

    questionsaboutwhetherfindingsonshort-termeffectivenessofopi-

    oid therapy can be extrapolated to estimate benefits of long-term

    therapyforchronicpain.Thus,itisimportanttoconsiderstudiesthat

    provide data on long-term benefit. For opioid-related harms (over-

    dose, fractures, falls, motor vehicle crashes), studies were includedwith outcomes measured at shorter intervals because such out-

    comes canoccur early during opioidtherapy.

    The review also considered evidence related to initiation and

    titration, harms and adverse events, and risk mitigation. CDC up-

    datedthe reviewwith morerecent studies.Because long-termopi-

    oidusemaybeaffectedbyuseofopioidsforacutepain,CDCadded

    a clinical questiononthe effectsof prescribingopioids foracutepain

    on long-term use(Box 2).

    CDCupdatedthesystematicliteraturesearchusingsearchterms

    dence using methodsdevelopedby theGRADEWorkingGroup; and

    servational studies or randomized clinicaltrials withnotablelimita-

    tionsor clinical experience andobservation).We highlightimportant

    findings from thereview for each keyquestion(KQ)below.

    KQ1:Effectivenessand Comparative Effectiveness

    No study of opioid therapy vs placebo, no opioid therapy, or non-opioid therapy for chronic pain evaluated long-term (1 year) out-

    comes related to pain, function, or quality of life. Most placebo-

    controlled randomized clinical trials were 6 weeks or shorter in

    duration.7

    KQ2:Harms and Adverse Events

    Long-term opioid therapy was associated with problematic pat-

    terns ofopioiduse leadingto clinically significantimpairmentor dis-

    tress. Varyingterminologyhas beenused to reflect thispattern, in-

    cluding “addiction” (more informally), “opioid abuse and opioid

    dependence” (per Diagnostic and Statistical Manual of Mental Dis-

    orders [Fourth Edition][DSM-IV ] or International Classification of Dis-

    eases, Ninth Revision, Clinical Modification [ICD-9-CM]), and “opi-

    oid use disorder” (per DSM-5). Such disorders are manifested bysimilar criteria, including unsuccessful efforts to reduce or control

    useand useresulting in socialproblemsand a failure tofulfill major

    roleobligationsatwork,school,orhome.Disordersaredifferentfrom

    tolerance (diminished response to a drug with repeated use) and

    physical dependence (adaptation to a drug that produces symp-

    toms of withdrawal when the drug is stopped), both of which can

    exist without a diagnosed disorder.

    Long-termopioidtherapy wasassociated withan increased risk

    of an opioid abuse or dependence diagnosis (as defined by ICD-

    9-CM codes) vs no opioid prescription.14 In primary care settings,

    prevalenceof opioid dependence(usingDSM-IV criteria)rangedfrom

    3%to 26%.15-17 Factorsassociated withincreasedrisk of misuse in-

    cluded history of substance use disorder, younger age, major de-pression, and use of psychotropicmedications.16,18Opioiduse was

    associated with a dose-dependent increased risk of fatal and non-

    fatal overdose19,20 (Table 2). Otherrisks associated withopioiduse

    includedcardiovascularevents,28,29endocrinologicharms,30,31and

    road trauma.32

    KQ3:Dosing Strategies

    Initiationoftherapywithanextended-release/long-acting(ER/LA)opi-

    oidwas associated with greaterrisk of nonfatal overdose than initia-

    tion with animmediate-release opioidin 1 study, with riskgreatestin

    thefirst2 weeks after initiation oftreatment.33Three studiesof vari-

    ous ER/LA opioids found no clear differences related to pain or

    function34-36;thereweremixedfindingsregardingthedifferencesbe-

    tween methadone and morphine in overall risk for nonfatal or fatal

    overdose,37-39 suggestingthat risks of methadone might vary in dif-

    ferent settings. One study found no differences between more lib-

    eral dose escalation and maintenance of current doses after 12

    months40; evidence on other comparisons related to opioid dosing

    strategieswas toolimited to determine effectson outcomes.

    No study evaluated the effectiveness of risk mitigation strategies.

    KQ5: Effect of OpioidTherapyfor Acute Pain on Long-term Use

    Studies examining patientswho underwent low-risk surgery or ex-

    perienced low back pain from injury revealed that opioid therapy

    prescribed for acutepain was associated with greater likelihood of 

    long-term use.46,47Comparedwithnoearlyopioiduseforacutelow

    backpain,theadjustedoddsratioforreceiving5ormoreopioidpre-

    scriptions from 30 to 730days after onset was 2.08 (95% CI,1.55-

    2.78)for1 to140 morphine milligramequivalents(MME)perday and

    increasedto6.14(95%CI,4.92-7.66)for450MMEormoreperday. 47

    Box2. KeyQuestions forthe ClinicalEvidence Review

    KeyQuestion1. Effectivenessand Comparative Effectiveness

    a. In patients with chronic pain, what is theeffectivenessof 

    long-term opioid therapy vs placebo or no opioid therapy

    for long-term(1 year) outcomes related to pain,function,

    andquality oflife?

    b. Howdoes effectivenessvary depending on: (1) the specific type

    or causeof pain (eg,neuropathic, musculoskeletal [includinglow

    back pain], fibromyalgia, sickle celldisease,inflammatory pain,

    and headache disorders); (2) patient demographics (eg,age, race,

    ethnicity, gender); and (3) patient comorbidities (includingpast

    or current alcohol or substanceuse disorders, mental health

    disorders, medical comorbidities, and highrisk foraddiction)?

    c. In patientswithchronic pain, whatis thecomparativeeffectiveness

    of opioidsvs nonopioid therapies (pharmacologicor

    nonpharmacologic) on outcomes relatedto pain,function,

    andqualityof life?

    d. In patients withchronic pain,what is the comparative effective-

    nessof opioids plus nonopioidinterventions(pharmacologic or

    nonpharmacologic) vs opioids or nonopioidinterventionsalone

    on outcomes related topain,function, quality oflife,and dosesof 

    opioids used?

    KeyQuestion2. Harmsand AdverseEvents

    a. In patientswithchronic pain, whatarethe risks ofopioids vs

    placeboor noopioidon (1)opioidabuse, addiction,and related

    outcomes;(2) overdose;and (3)otherharms, including

    gastrointestinal-related harms,falls, fractures, motorvehicle

    crashes, endocrinologic harms,infections,cardiovascular events,

    cognitive harms,and psychologicalharms (eg, depression)?

    b. How do harms vary depending on(1) thespecific type or cause of 

    pain (eg, neuropathic, musculoskeletal [includingback pain],

    fibromyalgia, sickle cell disease, inflammatory pain,headache

    disorders); (2) patient demographics; (3) patient comorbidities

    (including past orcurrent substanceuse disorder orat high risk

    foraddiction);and (4) thedoseof opioids used?

    KeyQuestion3. Dosing Strategies

    a. In patientswithchronic pain, whatis thecomparativeeffectivenessofdifferentmethodsfor initiatingand titrating opioidson

    outcomes relatedto pain, function, andquality oflife;risk of 

    overdose,addiction,abuse, ormisuse; anddosesof opioidsused?

    b. In patients withchronic pain,what is the comparative effective-

    ness of immediate-release vs extended-release/long-acting

    (ER/LA) opioids on outcomes related to pain,function, and

    quality oflife;riskof overdose, addiction, abuse,or misuse; and

    dosesof opioids used?

    c. In patients with chronic pain, what is thecomparative effective-

    ness ofdifferent ER/LAopioids on outcomes related to pain,

    function,and quality oflife andriskof overdose, addiction,

    abuse, or misuse?

    d. In patients withchronic pain,what is the comparative effective-

    nessof immediate-release plus ER/LAopioidsvs ER/LA opioids

    aloneon outcomes related to pain, function, andqualityof life;risk ofoverdose,addiction, abuse,or misuse; anddosesof 

    opioids used?

    e. In patients with chronic pain, what is thecomparative

    effectivenessof scheduled, continuous vs as-needed dosing of 

    opioids onoutcomesrelatedto pain, function, andqualityof life;

    risk ofoverdose, addiction, abuse,or misuse; anddoses of 

    opioids used?

    f. In patients with chronic pain on long-termopioid therapy, what is

    the comparative effectiveness of doseescalation vs dose

    maintenanceor useof dose thresholds on outcomes related to

    pain, function, andqualityof life?

    g. In patients on long-termopioid therapy, whatis the comparative

    effectivenessof opioid rotation vs maintenance of current opioid

    therapy onoutcomesrelated to pain, function,and quality of life;

    anddoses of opioids used?

    h. In patients on long-termopioid therapy, whatis the comparative

    effectivenessof different strategies for treating acute

    exacerbationsof chronic pain on outcomesrelated to pain,

    function,and quality of life?

    i. In patients onlong-term opioidtherapy, what arethe effects of 

    decreasing opioid dosesor of tapering offopioids vs continuation

    ofopioids onoutcomesrelated to pain, function,quality oflife,

    and withdrawal?

     j. In patients on long-term opioid therapy, what is the comparativeeffectivenessof different tapering protocolsand strategies on

    measures related to pain,function,quality of life, withdrawal

    symptoms, and likelihood of opioid cessation?

    KeyQuestion4. RiskAssessment andRisk MitigationStrategies

    a. In patients withchronicpain beingconsidered for long-term

    opioid therapy, whatis the accuracyof instruments for predicting

    riskof opioid overdose, addiction, abuse, or misuse?

    b. In patients with chronic pain, what is theeffectivenessof useof 

    riskpredictioninstrumentson outcomes related to overdose,

    addiction,abuse, or misuse?

    c. Inpatientswith chronic pain prescribedlong-term opioid therapy,

    whatis the effectiveness of risk mitigationstrategies, including

    (1) opioid management plans, (2) patient education,(3) urine

    drug screening, (4) use of prescription drug monitoring program

    data,(5) use of monitoring instruments, (6) morefrequent

    monitoring intervals, (7) pill counts, and(8) useof 

    abuse-deterrent formulations on outcomesrelated to overdose,

    addiction,abuse, or misuse?

    d. What is the comparative effectivenessof treatmentstrategies for

    managing patients with addiction to prescription opioids on

    outcomes related to overdose, abuse, misuse, pain,function, and

    quality of life?

    Key Question5. Effectof OpioidTherapy forAcute Pain

    on Long-termUse

    a. In patients with acute pain, what arethe effects ofprescribing

    opioidtherapyvs not prescribingopioid therapy for acute pain on

    long-termopioid use?

    Contextual Evidence Review

    CDCconducted a contextual evidence review to assist in develop-

    ing the recommendations by providing an assessment of the bal-

    ance ofbenefitsand harms,values andpreferences, andcost, con-

    sistent with the GRADE approach (Box 3). Rapid review methods

    wereused to streamlinethe process andobtainevidencequickly(eg,

    by limitingdatabase searchesand summarizingstudy qualitybased

    on author reports rather thanapplying objectivequalityratingpro-tocols). Full details on methodology, including data sources and

    searches, inclusion criteria, study selection,and dataextraction and

    synthesis, and findings are available in the MMWR report.11 In this

    article, we summarize benefits and harms of nonopioid therapies

    found in theclinicalliterature and harms of opioidtherapy, includ-

    ingadditional studies notincludedin theclinicalevidencereview (eg,

    studies not restricted to patients with chronic pain).

    Severalnonpharmacologicand nonopioid pharmacologictreat-

    ments were found to be effective for chronic pain in studies rang-

    ing in duration from 2 weeks to 6 months48-66 (Table 3). For ex-

    ample,cognitivebehavioral therapy (CBT)had smallpositive effects

    on disability and catastrophic thinking.66 Exercise therapy re-

    duced pain and improved function in chronic low back pain54; im-

    provedfunction andreducedpainin osteoarthritisof theknee51and

    hip52; andimproved well-being, fibromyalgiasymptoms,andphysi-

    cal function in fibromyalgia.48 Multimodal and multidisciplinary

    therapies helped reduce pain and improve function more effec-

    tively than single modalities.55,67 Multiple guidelines recom-

    mended acetaminophen as first-line pharmacotherapy for

    osteoarthritis68-73 or for low back pain74 and nonsteroidal anti-

    inflammatory drugs (NSAIDs)as first-line treatmentfor osteoarthri-

    tis or low back pain70,74; first- and second-line drugs for neuro-

    pathic pain include anticonvulsants (gabapentin or pregabalin),

    tricyclicantidepressants,and serotonin-norepinephrinereuptakein-

    hibitors (SNRIs).75-78 Nonsteroidal anti-inflammatory drugs have

    been associated with hepatic, gastrointestinal, renal, and cardio-

    vascular risks.63,73,79

    testing,96 as well as co-prescription of naloxone.97 In addition,

    methadoneand buprenorphine foropioid use disorder were found

    to increase retentionin treatmentand to decrease illicit opioiduseamong patients with opioid use disorder, and some studies sug-

    gestthat effectivenessis enhanced whenpsychosocial treatments

    are used in conjunction with medication-assisted therapy.98-102

    Recommendations

    The guideline includes 12 recommendations (Box 5). GRADE

    recommendation categories were based on the following

    assessment:

    • Noevidenceshowsalong-termbenefitofopioidsinpainandfunc-

    tion vsno opioids forchronicpainwithoutcomesexaminedat least

    1 yearlater (withmost placebo-controlledrandomizedclinical trials

    6 weeks in duration).

    • Extensive evidence shows the possible harms of opioids (includ-

    ing opioid use disorder, overdose, and motor vehicle injury).• Extensive evidence suggests some benefits of nonpharmaco-

    logic and nonopioid pharmacologic therapy, with less harm.

    Determining When to Initiate or Continue Opioids

    forChronic Pain

    1. Nonpharmacologic therapy and nonopioid pharmacologic

    therapy are preferred for chronic pain. Clinicians should consider

    opioid therapy only if expected benefits for both pain and func-

    tionareanticipatedtooutweighriskstothepatient.Ifopioidsare

    used, they should be combined with nonpharmacologic therapy

    and nonopioid pharmacologic therapy, as appropriate.  (Recom-

    mendationcategory: A; evidence type: 3)

    Nonpharmacologictherapy (such as exercisetherapy andCBT)

    shouldbeusedtoreducepainandimprovefunctioninpatientswith

    chronic pain. Aspects of these approaches canbe used even when

    there is limited accessto specialtycare. For example, primary care

    clinicians can encourage patients to take an active role in the care

    plan and support patientsin engagingin exercise. Nonopioidphar-

    macologic therapy (such as NSAIDs, acetaminophen, anticonvul-sants, andSNRIs)should be usedwhen benefits outweighrisks and

    should be combinedwith nonpharmacologictherapy. Opioids should

    not be consideredfirst-line or routine therapy for chronic painout-

    side of activecancer, palliative, andend-of-lifecare, given small to

    moderate short-termbenefits,uncertainlong-termbenefits, andpo-

    tential for serious harms; althoughevidence on long-termbenefits

    of nonopioid therapies is also limited, these therapies are also as-

    sociated with short-term benefits, and risks are much lower. This

    doesnotmean that patients shouldbe requiredto sequentially “fail”

    nonpharmacologic and nonopioid pharmacologic therapy before

    proceedingto opioid therapy. Rather, expected benefits specific to

    the clinical context should be weighed against risks before initiat-

    ing therapy. In someclinicalcontexts (eg, headache, fibromyalgia),expectedbenefitsof initiatingopioidsare unlikelyto outweighrisks

    regardless of previous nonpharmacologic and nonopioid pharma-

    cologictherapiesused. Inother situations(eg, seriousillnessin a pa-

    tientwithpoorprognosisforreturntopreviousleveloffunction,con-

    traindicationsto other therapies,and clinicianand patientagreement

    that the overriding goal is patient comfort), opioids might be ap-

    propriateregardless of previoustherapies used.If opioidsare used,

    theyshouldbe combinedwithnonpharmacologic therapyand non-

    opioid pharmacologic therapy, as appropriate, to provide greater

    benefits to patients.

    2. Before starting opioid therapy for chronic pain, clinicians

    should establish treatment goals with all patients, including real-

    istic goals for pain and function, and consider how opioid

    therapy will be discontinued if benefits do not outweigh risks.

    Clinicians should continueopioid therapy only if there is clinically

    meaningful improvement in pain and function that outweighs

    risks to patient safety. (Recommendation category: A; evidence

    type: 4)Before opioid therapy is initiated for chronic pain, clinicians

    should determine how effectiveness will be evaluated and should

    establish treatment goals with patients. Clinicians seeing new

    patients already receiving opioids should establish treatment

    goals for continued treatment. Goals should include improvement

    in both pain relief and function. However, there are some clinical

    circumstances under which reductions in pain without improve-

    ment in physical function might be a more realistic goal (eg, dis-

    eases typically associated with progressive functional impairment

    or catastrophic injuries such as spinal cord trauma). Experts noted

    that function can include emotional and social as well as physical

    dimensions. In addition, experts emphasized that mood has

    important interactions with pain and function. Clinicians may use

    validated instruments such as the 3-item “Pain average, interfer-

    ence with Enjoyment of life, and interference with General activ-

    ity” (PEG) Assessment Scale103 to track patient outcomes. Clini-

    cally meaningful improvement has been defined as a 30%

    improvement in scores for both pain and function.104 Because

    depression, anxiety, and other psychological comorbidities often

    coexist with and can interfere with resolution of pain, clinicians

    should use validated instruments to assess for these conditions

    and ensure that treatment for these conditions is optimized.

    3. Before starting and periodically during opioid therapy,

    clinicians should discuss with patients known risks and realistic

    benefits of opioid therapy and patient and clinician responsibili-

    ties for managing therapy.  (Recommendation category: A;

    evidence type: 3)Cliniciansshouldensurethatpatientsareawareofpotentialben-

    efitsof,harms of, andalternativesto opioids before startingor con-

    tinuing opioid therapy. Clinicians are encouraged to haveopen and

    honest discussions withpatientsto inform mutual decisionsabout

    whether to start or continue opioid therapy. Important consider-

    ations include the following:

    • Be explicit and realistic about expected benefits of opioids, ex-

    plainingthat whileopioidscan reduce painduringshort-term use,

    there is no good evidence that opioids improve pain or function

    with long-term useand that complete reliefof pain is unlikely.

    • Emphasize improvement in function as a primary goal and that

    function canimprove even when pain is stillpresent.

    • Advise patients about serious adverse effects of opioids, includ-ing potentially fatal respiratory depressionand development of a

    potentially serious lifelong opioid use disorder.

    • Advise patients about common effects of opioids, suchas consti-

    pation, dry mouth, nausea, vomiting, drowsiness, confusion, tol-

    erance, physical dependence, and withdrawal symptoms when

    stopping opioids.

    • Discuss effects that opioids may have on ability to safely operate

    a vehicle, particularlywhenopioids areinitiated, whendosagesare

    increased,orwhenothercentralnervoussystemdepressants,such

    as benzodiazepines or alcohol, are used concurrently.

    Box3. Key Areas forthe Contextual Evidence Review

    • Effectiveness of alternativetreatments, including

    nonpharmacologic (eg, cognitivebehavioral therapy, exercise

    therapy, interventionaltreatments, multimodal pain treatment)

    and nonopioidpharmacologictreatments (eg,acetaminophen,

    nonsteroidal anti-inflammatory drugs, antidepressants,

    anticonvulsants), including studies of any duration.

    • Benefitsand harms of opioid therapy (including additionalstudies not included in the clinical evidence review,such as

    studies thatwere not restrictedto patients withchronicpain,

    evaluatedoutcomesat any duration, performed ecological

    analyses, or used observationalstudy designs other thancohort

    and case-cohort control studies) related to specific opioids, high-

    dosetherapy, co-prescriptionwith other controlled substances,

    duration of use,special populations, and potential usefulness of 

    riskstratificationor mitigationapproaches; in addition to

    effectiveness of treatments associated with addressing potential

    harms of opioid therapy (opioid use disorder).

    • Clinician and patient values and preferences related to opioids

    and medicationrisks, benefits,and use.

    • Resource allocation, including costs and economicefficiency of 

    opioid therapy and riskmitigationstrategies.

    • Clinical guidelines relevant to opioidprescribing to complementthe Centers for DiseaseControl and Prevention recommendations

    (eg, guidelines on alternative treatments, guidelines with

    recommendations relatedto specificclinician actionssuch as

    urine drugtesting or opioid tapering protocols).

    Opioid Selection, Dosage, Duration, Follow-up,

    and Discontinuation

    4.When startingopioidtherapy forchronicpain,cliniciansshould

    prescribeimmediate-releaseopioids instead of extended-release/

    long-acting (ER/LA) opioids. (Recommendation category: A; evi-

    dence type: 4)

    Clinicians should not initiate opioid treatmentwith ER/LA opi-

    oids and should not prescribe ER/LA opioids for intermittent use.

    In general, avoiding the use of immediate-release opioids in com-

    bination with ER/LA opioids is preferable.

    When anER/LAopioid is prescribed, usinga product with pre-

    dictable pharmacokinetics and pharmacodynamics is preferred to

    minimize unintentional overdose risk.• Methadoneshouldnotbe thefirstchoice foran ER/LAopioid. Only

    clinicianswho arefamiliar withmethadone’s uniquerisk profileand

    who are prepared to educate and closely monitor their patients—

    including risk assessment for QT prolongation and consideration

    of electrocardiographic monitoring—should consider prescribing

    methadone for pain.

    • Because dosing effects of transdermal fentanyl are often misun-

    derstood by both clinicians and patients, only clinicians who are

    familiarwith thedosingand absorption propertiesof transdermal

    fentanyl andare prepared to educate their patients about itsuse

    should consider prescribingit.

    5. When opioids are started, clinicians should prescribe the

    lowest effective dosage. Clinicians should use caution whenpre-scribing opioids at any dosage, should carefully reassess evi-

    dence of individual benefits and risks when considering increas-

    ingdosageto 50 morphine milligramequivalents(MME) or more

    per day, and shouldavoid increasing dosage to 90 MMEor more

    perdayor carefullyjustify a decisionto titrate dosage to90 MME

    or more perday. (Recommendation category: A; evidence type:3)

    Clinicians should start opioids at the lowest effective dosage,

    use caution when increasing opioid dosages, and increase dosage

    bythe smallest practical amount.Before increasingtotalopioiddos-

    age to50 MME ormore perday, clinicians shouldreassess whether

    opioids are meetingthe patient’s treatmentgoals.If a patient’s opi-

    oid dosagefor all sources of opioids combined reaches or exceeds

    50 MME per day, clinicians should implement additional precau-

    tions, including increased frequency of follow-up and considering

    offering naloxone. Clinicians should avoid increasing opioid dos-

    ages to 90 MME or more per day or should carefully justify a deci-

    sionto increasedosageto 90MME ormore per day based onindi-vidualizedassessmentofbenefitsandrisksandweighingfactorssuch

    as diagnosis, incremental benefits for pain and function relative to

    harmsas dosagesapproach90 MMEper day, other treatments and

    effectiveness, and recommendations based on consultation with

    pain specialists. If patients do not experienceimprovement in pain

    and functionat 90 MME ormoreper day, or ifthere are escalating

    dosage requirements,cliniciansshoulddiscuss other approaches to

    painmanagementwith thepatient,consider workingwith patients

    to taper opioids to a lower dosageor to taper anddiscontinue opi-

    oids, and consider consulting a pain specialist.

    Established patients already prescribed high dosages of 

    opioids (90 MME/d), including patients transferringfromothercli-

    nicians, should be offered the opportunity to reevaluate their con-

    tinueduse ofopioids athighdosages inlightof recentevidence re-

    garding the association of opioid dosage and overdose risk. For

    patients who agree to taper opioids to lower dosages, clinicians

    should collaboratewith thepatient on a tapering plan.6.Long-termopioiduse oftenbegins withtreatment ofacute

    pain. When opioids areused foracutepain, clinicians shouldpre-

    scribe thelowest effectivedoseof immediate-releaseopioidsand

    should prescribe no greater quantity than needed for the ex-

    pected duration of pain severe enoughto require opioids. Three

    days orlesswilloftenbe sufficient; more than 7 days willrarelybe

    needed. (Recommendation category: A; evidence type:4)

    Acute pain can often be managed without opioids. When

    diagnosis and severity of nontraumatic, nonsurgical pain are rea-

    sonably assumed to warrant the use of opioids, clinicians should

    Palliative, and End-of-Life Care

    DeterminingWhen to Initiateor Continue Opioids for Chronic Pain

    1. Nonpharmacologic therapy and nonopioidpharmacologictherapy

    are preferred forchronic pain.Clinicians should consider opioid

    therapy only if expectedbenefits for both pain andfunctionare

    anticipated to outweigh risksto thepatient.If opioids areused, they

    should be combinedwith nonpharmacologic therapy and nonopioid

    pharmacologic therapy, as appropriate.

    2. Before starting opioid therapy forchronic pain,clinicians should

    establishtreatment goalswith all patients,includingrealisticgoals

    for pain andfunction, andshould considerhow therapy will be

    discontinued if benefits do not outweigh risks. Cliniciansshould

    continueopioid therapy onlyif there is clinicallymeaningful

    improvement in pain and function thatoutweighs risksto

    patient safety.

    3. Before starting and periodically during opioid therapy, clinicians

    should discuss withpatients known risksand realisticbenefitsof 

    opioid therapy and patient and clinician responsibilitiesfor

    managing therapy.

    Opioid Selection,Dosage, Duration,Follow-up,and Discontinuation

    4. Whenstartingopioid therapy for chronic pain,clinicians should

    prescribeimmediate-release opioids instead of extended-release/

    long-acting (ER/LA) opioids.

    5. Whenopioids are started, clinicians should prescribe the lowest

    effective dosage. Cliniciansshould use caution whenprescribing

    opioids at any dosage, should carefullyreassessevidence of 

    individual benefits and riskswhen increasing dosage to 50 morphine

    milligram equivalents (MME) or moreper day, and should avoid

    increasing dosageto 90 MME or more perday or carefullyjustifya

    decision totitrate dosageto 90 MMEor more perday.

    6.Long-termopioid useoften beginswithtreatment of acute pain.

    When opioids areusedfor acute pain,clinicians shouldprescribe the

    lowest effectivedose of immediate-release opioids and should
