Abstract Background: The degree to which patients participate in their care can have a positive impact on health outcomes. This review aimed to map the current literature on patient participation behaviours in interactions with physicians and the extent to which differences in these behaviours can be explained by socio‐economic status (SES). Search strategy: Four electronic databases were searched from 1980 onwards using key words related to socio‐economic status and patient participation behaviours. Study selection: Titles, abstracts and full texts were screened by two reviewers, with the second reviewer screening 20% of all entries. Data extraction: Data on year of publication, country, patient population, setting, patient participation behaviour studied, and SES measure used were extracted. Main results: Forty‐nine studies were included in the review. Most studies were conducted in the United States, and the most commonly studied patient participation behaviour was involvement in decision making. Most studies measured SES using education as an indicator, with very few studies using occupation as a measure. Many studies did not report on participants’ medical condition or study setting. Patient participation in their health‐care appointment increased with increasing SES in 24 studies, although in 27 studies no significant association was found. Discussion and conclusions: Current literature was found to be mainly US‐centric. Many studies did not specify participants’ medical condition or in what setting the study was undertaken. More studies are needed on less commonly studied patient participation behaviours. It would be helpful for further studies to also include a wider range of SES indicators.

Patient‐centredcarehasbeenassociatedwithbeneficialoutcomessuchasagreateradherencetotreatment,satisfactionandimprovedqualityof life.1‐4The InstituteofMedicinedefinespatient‐centredcareasprovidingcarethat is respectfulofandresponsiveto indi‐vidualpatientpreferences,needsandvalues,ensuringthatpatientvaluesguideallclinicaldecisions.5Thus,theextenttowhichpatientsparticipateindiscussionsduringtheirhospitalorclinicvisitsisseenasanimportantbarometerofpatient‐centredcare.Althoughthereisnouniversallyapplieddefinitiononwhattypeofbehavioursconsti‐tutespatientparticipationinclinicalvisits,6moststudiesfocusingonpatientparticipationbehavioursinvolvearangeofbehaviourssuchasquestionasking,raisingconcerns,andexpressingopinions,pref‐erencesandemotions.7

The Verlinde et al8 review also limited identification of litera‐tureexploringthesocialgradientindoctor–patientcommunicationand social gradient, to studies reporting the ‘social class relatedconceptsof’educational level, incomeoroccupation.Confusingly,threeofthestudiesincludedinthisreviewmeasuredSESusing‘so‐cialclass’,althoughtheauthorsdidnotspecifyexactlyhowthiswasdefined.However, thereareseveralother indicatorsofSESwhichmayalsobeassociatedwithpatientparticipationbehaviours suchas thepatients’health insurancestatusor receiptofbenefits,andalsoarea‐levelmeasuresofdeprivationrelatedtothepatients’homeaddress(IndicesofMultipleDeprivation),whichmaynothavebeencapturedpreviously,andmaystillberelevant.9Bearinginmindthepotentialimportanceofthisareaanditslikelyrelationshiptobenefi‐cialhealthoutcomes,weundertookasystematicmappingreviewtoidentifywhatresearchhadbeendonewhichspecificallyexaminedhowpatientparticipationbehavioursindoctor–patientinteractionsare related todifferences inawide rangeofpossiblemeasuresofsocio‐economicstatus.

Our research question was as follows: How and why does ten‐dencytoanddesireforpatientparticipationbehavioursinhealth‐careconsultationswithphysiciansvaryaccordingtoSESandwhatmeasuresofSEShavebeenexplored?Forthepurposeofthisre‐view,wedefinedpatientparticipationbehavioursasconsistingofquestion asking, raising concerns, involvement in decision mak‐ing,rapportbuilding,andexpressionofopinions,preferencesandemotions.

3  | DATA SOURCES

Anelectronic searchwasundertakenof the followingdatabases:Medline,CINAHL,PsychINFOandWebofScience.Literaturewassearchedfrom1980to2018;sincepriorto1980,therewasmuchlesselectronic indexing.Apilotsearchwasconductedto identifypotentiallyeligiblepapers,assesstheamountofrelevantliteraturein the field and identify suitable search terms. At this stage,wefound that including screening appointments and emergency ad‐missionsmadethescopeofthereviewfartoobroadandunman‐ageable;therefore,wedecidedtointroducelimitsintheelectronicsearchtermsregardingongoingdoctor–patient relationships.Theelectronic search contained free text and subject headings in‐cluding patient‐centred care, question asking, raising concerns,involvement in decision making, building rapport, expression ofpreferences,emotionsoropinions,educationalstatus,income,oc‐cupational status, employment, social class and socio‐economicfactors.ThiswasmodifiedasnecessaryforeachdatabaseandcanbefoundinAppendixS1.

Inclusioncriteriaforthereviewwereasfollows:

• Studies involving patient perspectives on actual and desiredquestion asking, raising concerns, involvement in decisionmak‐ing,rapportbuilding,orexpressionofopinions,preferencesandemotions.

• SESgradientmeasuredintheformofeducation,income,occupa‐tionor‘othermeasures’whichincludedpatients’healthinsurancestatus, incomeindicatorsofstatebenefitsandarea‐basedmea‐suresrelatingtothepatients’homeaddress.

• Publishedin1980onwards.• Studiesinvolvingadultpatients.• Onlystudieswhichfocusedondoctor–patientinteractions.• WritteninEnglishlanguageonly.

The majority of studies used questionnaires to collect data(75.5%),withonlyfivestudiesusingqualitativetechniquessuchasinterviewsorfocusgroups,andonlytwostudies13,14wereinterven‐tions.Bothinterventionswerepilotstudieswithnocontrolgroup.The most commonly studied condition was cancer (20.4%), withfourstudiesrecruitingarthritispatients,andfourstudieswithdia‐betespatients.Moststudiesdidnotspecifywhatcondition(ifany)theirparticipantshad (36.7%). ‘Other’conditions includedasthma,chronicpain,HIV,multiplesclerosisandinflammatoryboweldisease(Figure3).NoneofthethreeUKstudiesrecruitedcancerpatients.

Themostcommonsettingforstudiesinvolvedsecondaryorter‐tiary care (44.9%),with primary care being the setting in only 11studies.Unfortunately,16studiesdidnotspecifywhichsettingtheirresearch referred to when collecting data from participants. Themostcommonlystudiedpatientparticipationbehaviourwasinvolve‐mentindecisionmaking(46studies),whereasfivestudiesexaminedraising concerns,14‐18 and only one study looked at rapport build‐ing.19Question asking and expression of opinions, preferences oremotionswasmorecommonlystudied,featuringin13and12stud‐ies, respectively.The rapportbuildingstudy recruitedparticipantsfromthegeneralpopulationandsotherewasalackofstudieswhichfocusedonrapportbuildingwhichinvolvedparticipantsinahealthsetting.Threeoftheraisingconcernsstudieswerewithbreastcan‐cerpatients(Table2).

Themostcommonlyusedmeasuretoexplorerelationshipsbe‐tween patient participation behaviours and SES was educationallevel (45 studies).Only four studiesusedoccupationasan indica‐torofSES,20‐23andonlytwostudiesusedacompositemeasureofdeprivation.24,25Onestudymeasuredhousingsituationandreceiptofbenefits,26oneusedacompositemeasureofsocialclass,27 and onelookedatfinancialstrainandfinancesattheendofthemonth.28

It isalsoimportanttonotethatmanystudiesexaminedmorethanonetypeofpatientparticipationbehaviourorusedmorethanonemeasureofSES.Moststudies(33)usedmorethanonemeasureofSES,whereasonly18studiesexaminedmorethanonetypeofpa‐tientparticipationbehaviour(Table2).

Table1showsthedirectionofassociations reported in the in‐cludedstudies.Ofthe49 includedstudies,5didnotperformsta‐tistical analyses as they had employed qualitativemethodologies.Positive associations between SES and patient participation be‐haviours (PPBs) were reported by 24 studies, while 5 studies re‐ported negative associations. Twenty‐seven studies reported noassociationbetweenatleastsomeoftheirvariables.ElevenstudiesreportedassociationsofdifferingdirectionsfordifferentmeasuresofSESordifferentPPBswithintheirstudy.Sincethestudiesweresomixedintermsofdesign,participants’condition,outcomesandsetting,itwasnotappropriatetoundertakeanymeta‐analyses.

Althoughpreviousstudieshavefoundthatrapportbuilding inthedoctor–patientrelationshipcanhaveanumberofpositiveout‐comes, including treatment satisfaction, understanding health in‐formation,copingandadherencetotreatment,1,3,31onlyonestudywas identifiedwhich lookedathowthisbehaviourwasrelatedtoSESdifference,andsofurtherresearch inthisarea isparticularlyneeded.

Most studies used more than one measure of SES which insome cases allowed a comparison of the effects of each differ‐entmeasure,althoughinsomeofthese,notalltheSESvariableswereentered into theanalysisbutweresimplyusedtodescribethesample.Theobjectiveofourstudywastomaptheliteratureinthisarearatherthantoproduceasynthesisacrossseveraltypesofstudies;however,weextracteddatafromincludedstudiesonwhether a statistically significant association between SES andPPB had been reported. This indicated that although PPB wasfoundtobe related toSES inabouthalfof thestudies, inabouthalf, theywerenot.Summarizingresultsaremademoredifficultby the heterogeneitywhich exists between studies in this area,and the range of different measures of SES and indicators ofPPBwhichhadbeenused.Forexample,althoughseveralstudiesshowed an association with education and patient participationbehaviours,asmanyas17studiesfoundnostatisticallysignificantassociationbetweenthetwovariables;andsotherelationshipislikelytobecomplex.Ontheotherhand,fewstudiesseemtohavefoundasignificantassociationbetweenpatientparticipationbe‐haviours and employment or income. Larger andmore sophisti‐cated studies are needed, using a rangeof SES indicators and amorein‐depthdescriptionofpatientparticipationbehaviours,andthesettinginvolved.

Whilethemostcommonconditionstudiedwascancerandthemost common settingwas secondary or tertiary care, 36.7% ofstudies did not specifywhat condition (if any) their participantswerediagnosedwithorwhathealth‐caresettingtheirquestionsregardingpatientparticipationreferredto.Thisispotentiallyim‐portantinformationwhichismissingfromthesestudies,assettingand condition which the patient is consulting for can influencea patient's preferred and experienced level of participation in aconsultation.7,32,33

Most studies included in the review were conducted in theUnitedStates,makingthecurrentresearchinthisareaveryUS‐cen‐tric.Thismaylimitthegeneralizabilityoftheresultsofthesestudies,asothercountrieshavedifferentlystructuredhealth‐caresystemswhichmight influencepatient participationbehaviours. There is aneed formorestudiesonpatientparticipationbehavioursoutsideoftheUnitedStates.
