Abstract

Objective: In recent years, the importance of social differences in the physician-patient relationship has frequentlybeen the subject of research. A 2002 review synthesised the evidence on this topic. Considering the increasingimportance of social inequalities in health care, an actualization of this review seemed appropriate.Methods: A systematic search of literature published between 1965 and 2011 on the social gradient in doctor-

patient communication. In this review social class was determined by patient

s income, education or occupation.Results: Twenty original research papers and meta-analyses were included. Social differences in doctor-patientcommunication were described according to the following classification: verbal behaviour including instrumentaland affective behaviour, non-verbal behaviour and patient-centred behaviour.Conclusion: This review indicates that the literature on the social gradient in doctor-patient communication thatwas published in the last decade, addresses new issues and themes. Firstly, most of the found studies emphasizethe importance of the reciprocity of communication.Secondly, there seems to be a growing interest in patient s perception of doctor-patient communication.Practice implications: By increasing the doctors awareness of the communicative differences and by empoweringpatients to express concerns and preferences, a more effective communication could be established.

Keywords: Communication, Physician-patient relations, Social class

IntroductionIn 1977 a commission under the lead of Sir FrancisBlack published the famous Black report, illustrating theexistence of a social gradient in health in the UK. Thepublication of this report was the start of a new wave of research on social inequity [ 1]. Since then many studieshave confirmed the gradient in health between socialclasses [2-4]. Health differences between social groupsdue to underlying social mechanisms such as differentialaccess to care, social exclusion or poverty are a matterof major concern in today s public health research but

in spite of marked health improvements of the overallpopulation and efforts to overcome health inequalities,higher morbidity and mortality rates for the socio-eco-nomically disadvantaged are still found [ 5-8]. The causesfor these inequalities in health are multiple and

complex: a different distribution of power and resourcesamong social classes, different levels of exposure tohealth hazards, same level of exposure leading to differ-ential impacts, life-course effects and different socialand economic effects of being sick [ 2,9-16]. A prerequi-site for equity in health is equity in health care, definedas equal care for people in equal need of care. As Dahlg-ren and Whitehead quoted: Equity in health careincludes fair arrangements that allow equal geographic,economic and cultural access to available services for allin equal need of care [17].

An essential component of the delivery of health careis the relationship between the patient and the healthcare provider [ 18]. Several studies on communication inhealth care have repeatedly shown the importance of the doctor s communication skills [ 19]. By communicat-ing with a patient, a physician gets to know the patient sproblem and creates a therapeutic relationship necessary for its management and, if possible, its solution [ 20].The quality of the relationship between a doctor and a

verbal behaviour. Verbal behaviour can be defined as thespoken communication . The verbal elements of commu-nication can be divided into instrumental or task-focused verbal behaviour (e.g. question asking, information giving,etc.) and affective or socio-emotional behaviour (counsel-ling, positive and negative talk, etc.) reflecting the distinc-tion between cure and care [ 27,28].

However, some of the determinants of communicationdo not fit into the above categories but are related tothe concept patient-centeredness. Patient-centerednessis about seeing the patient as a person with a uniquepersonal history and individual needs. We can identify five dimensions: (1) using the bio-psycho-social perspec-tive, (2) approach the patient as a whole person, (3)

sharing power and responsibility, (4)building a therapeu-tic relationship and (5) considering the physician as aperson and acknowledging the influence of its personalqualities [29,30].

The communication variables in the selected articlesare classified to the following categories: verbal behaviour inc luding instrumental and affect ive behaviour;non verbal behaviour and patient-centred behaviour.The selected studies were grouped and analysed by theresearches according the three communication variables.

ResultsVerbal/non-verbal behaviourVerbal behaviour: instrumental behaviour

Instrumental behaviour is considered as all interactionsthat serve the cure part of the consultation. It can bedefined as technically based skills that are used in pro-

blem solving e.g. giving directions, giving information,asking clarification, asking questions, counselling, etc.[26,31]. Eleven studies explored the interaction betweenthe instrumental behaviour of the physician and/or thepatients, and the SES of the patient.

A meta-analysis conducted by Hall et al. explored thecorrelation between physicians communicative behaviour and the patient s outcome variables. Social classwas measured by income, education or other non-speci-fied social class indices. The study revealed a positiverelationship between patient s social class and informa-tion giving. Patients of a higher social class received notonly more overall communication but also more infor-mation [ 32]. Not only patients social class but also his/her communication style influences the doctor-patientcommunication. In a study by Street et al., social classwas measured by educational level. Physicians informa-tion giving was positively influenced by the patient scommunicative style such as question-asking, affectiveexpressiveness and opinion-giving. More affectiveexpressiveness and being assertive on the patient s side-which is strongly related to his/her educational level-leads to more information giving on the doctor s side.More educated patients receive more diagnostic andhealth information than their lower educated counter-

parts. However this study did not find a relationbetween the frequency of the patients question askingand his/her educational background [ 33].

The fact that adaptations in the physicians responsesmay, besides a function of patients personal or socialcharacteristics per se, also are the result of the patients

communicative actions, was confirmed by a secondstudy by Street et al. In this study they compared thedegree to which parents personal and interactive char-acteristics accounted for variation in doctor-parentinteractions during paediatric consultations. Social classwas measured as educational level. More educated

parents are not only more expressive and assertive butthey also ask more questions. All three of these commu-nication aspects lead to more information and directiongiving by the physician. Additionally, this study showsthat the parent s personal characteristics have less influ-ence on the physicians responses than their own com-munication behaviour [ 34].

Besides patient s communication style, doctors andpatients perceptions are an important aspect of the con-sultation and for the outcome of the consultation. In anobservational study, Martin et al. looked at how bothphysicians and patients perceive what happens duringthe consultation. Social class was measured by occupa-tion. From the patients point of view most emphasis of the consultation is put on prescribing, reassuring andreferring. Whereas physicians report that emphasis isput on active listening, supporting and giving advice.

Furthermore, physicians perceived they explained andlistened more to patients from higher social classes andalso examined them more than patients from lowersocial classes, but gave the latter more other help

which was not specified. They also said to examinemore and to give less advice to patients from lowersocial classes. However, patients did not report havingexperienced any of these differences [ 35]. The study of DeVoe et al. where social class was determined by family income and educational level, shows differentresults. This study suggests that patients perceptions of communication in healthcare settings vary widely by demographics and other individual patient characteris-tics. The poorest patients were less likely to report thatproviders always explained things so that they under-stood. Surprisingly, different levels of education werenot independently associated with any of the investi-gated communication measures [ 36]. These results arein line with the results from the study of Fiscella et al.,exploring whether educational level affected the visits of family physicians. Patients with a low educational levelhad a slightly larger proportion of the consultation timespent on physical examination and nutritional counsel-ling. Less time was spent on patients questions, asses-sing their health knowledge, negotiating and counselling,

chatting, and less screening tests were provided to them.On e could say that less educated people are approachedin a more directive way during the consultation. Lesseducated patients also saw their expectations less metduring the consultation, although they were as satisfiedas the more educated patients [ 37]. When looking at theoutcome of the consultation, Maly et al. studied theimpact of physician-patient communication on women sreceipt of, or planning for, breast reconstructive surgery.Social class was determined by educational level andwas included as a potentially confounding factor.Women who had graduated from high school were

more likely to report planning of breast reconstructivesurgery. This is positively associated with interactiveinformation-giving by the physician and greater patientperceived self-efficacy. These two communication fac-tors weakened the negative influence of education bar-riers. Empowering aspects of patient-physiciancommunication and self-efficacy may overcome thenegative effects of a lower education on receipt orplanned breast reconstructive surgery [ 38].

In line with the different consultation style, Taira et al.investigated whether the patients income level had aninfluence on the physicians discussion of health riskbehaviours. Concerning patients at risk, physicianstended to discuss diet and exercise more with highincome patients and smoking more with low incomepatients [ 39]. Discussing health risk behaviour is very important in consultation, especially for chronic condi-

tions like diabetes. In a cross-sectional survey by Pietteet al., general communication processes and diabetes-specific communication was examined. Socio-economicstatus was measured by means of educational achieve-ment. Patients with lower education levels reported bet-ter general and better diabetes-specific communicationthan their less-vulnerable counterparts. This could bedue to the fact that these patients have lower expecta-tions of their patient-provider relationship or greaterdiscomfort with criticizing them. Another introducedexplanation could be that health care providers spendmore time counseling patients which they perceive as inneed for extra attention or explanation [ 40].

Pendleton et al. considered four types of informationgiving. SES was measured by social class. There was asignificant difference in voluntary explanations given topatients from different social classes, independent of thedifferent types of problems; higher SES patients receivesignificantly more explanations even when the explana-tion was not explicitly requested by the patient [ 41].Also the study from Siminoff et al. where social classwas measured by income and educational level showedthat more biomedical talk was provided to higherincome patients compared to medium and low incomepatients and to patients with higher educational achieve-

ment. In general, physicians provided little psychosocialcounseling and education, however, they provided moreto their high and medium income patients as comparedto low-income patients. Patients that had more than ahigh school education and patients that reported a med-ium or high income asked more questions and showedmore proactive behavior such as volunteering informa-tion to the physician unasked. Physicians on their sideasked less educated patients and low income patientsmore questions about their disease and medical history [42].

Verbal behaviour: affective behaviour

The affective behaviour in doctor-patient communica-tion is part of the emotional domain [ 19] and consistsof all forms of social behaviour and social talk. Possibleaffective expressions are: showing concern, reassurance,reflection, signs of agreement or disagreement and para-phrasing [ 27 ,28]. Only three studies investigated theeffects and outcomes of affective behaviour.

The meta-analysis by Hall et al. (supra) explores thesocio-emotional behaviours such as social talk and posi-tive and negative talk. Although a link between theaspects of affective behaviour and the patients satisfac-tion and compliance can be identified, none of thesedeterminants were found to be related to any determi-nant of the patients social class [32 ]. On the otherhand, the studies of Street et al. (supra) concluded thatdoctors provided more comments of reassurance, sup-

port and empathy to the parents of children with cancerwhich were more affectively expressive (more specifically who expressed more negative affect). As patients with ahigher educational level are more affectively expressivethan their counterparts, it can be assumed that physi-cians show more affective behaviour towards thesepatients [ 33,34].

In the observational study from Siminoff et al. (supra),the emotional expressions by physicians varied by patient s demographic variables, with more emotionalutterances from their physician [ 42].Non-verbal behaviour

Non-verbal behaviour is one of the least investigatedtopics of doctor-patient communication, especially whenlooking at its interaction with determinants of socialclass. The effect of non-verbal behaviour is only men-tioned in two of the selected articles [ 41,43]. Non-verbalbehaviour can be operationalised in different ways suchas eye contact, tone of voice, laughter, facial expression,physical distance, nodding, etc. [ 26].

The meta-analysis by Hall et al. (supra) could notfind any research that was done on the associationbetween the physicians non-verbal behaviour and thepatients social class [32]. The same year of the Hallreview, Street and Buller examined the non-verbal

behaviour in doctor-patient interactions and the rela-tionship with patient s age, sex and social class mea-sured as educational level. No differences were foundin the level of non-verbal communication towardspatients with different educational level. However,when talking to higher educated patients the physi-cians reciprocated their body orientations more thanthey did with lower educated patients. Finally, this arti-cle refers to specific difficulties in coding non-verbalbehaviour, which is much more complex than categor-ising the verbal interactions [ 44].

diminished the negative influence of education barriersand acculturation [ 38]. The study of Stewart, where edu-cational level was a measure for social class, showed thatphysicians were more likely to appeal to the intellect of a patient with a university degree by justifying the drugprescription while on the other hand they offer moreemotional support and solidarity to patients with alower educational level [ 54]. As presented above, theamount of information given to patients is related topatients characteristics and to the patients communica-tive style. Hereby, the patients communicative style isnot only influenced by his/her educational level but alsoby the level of partnership building of the physician[33,34]. In the observational study mentioned above by Street et al. it appeared that higher educated patientsreceived more partnership building utterances [ 33].

Discussion and conclusionThe aim of the current review is to give the state of theart on the social gradient in doctor-patient communica-tion, to describe which aspects of the consultation areaffected by this social gradient, and whether an evolutionover time can be noticed comparing the results of olderstudies with those of newer studies. In this review wefound that patients from lower social classes (measuredby income, education or occupation) receive less socio-emotional talk, a more directive and a less participatory consulting style characterised by for example less invol- vement in treatment dec isions; a higher percentage of biomedical talk and physicians question asking; lowerpatient control over communication; less diagnostic andtreatment information and more physical examination.Doctors give more information, more explanations, more(emotional) support and adapt more often a shared deci-sion making style with higher SES participants.

This review also indicates that the literature on thesocial gradient in doctor-patient communication thatwas published after 2002, at least addresses new issuesand themes. Firstly, in the period 1965-2002, 42 articleswere selected for this review, while for the period 2002-2011, 87 articles were selected. These numbers indicatethat doctor-patient communication becomes a more

emerging topic in the research on delivering qualitativecare. Secondly, most of the more recent studies empha-size the importance of the reciprocity of communica-tion: the doctor might communicate differently according to the social status of the patient, and patientsmay adapt a different communication style accordingtheir social class. Patients with a high SES tend to askmore questions, ask for explanations, are more expres-sive and have a higher level of being opinionated thantheir lower SES counterparts [ 33,34,42,55].

Furthermore, there seems to be a growing interest inpatient s perception of doctor-patient communication.

While in the past, patient s perception was not takinginto account or no differences in perception were found,more recent studies show that low SES patients have thefeeling doctors fail to explain things in a way they canunderstand and spend less time with them [ 21,24,41].

These findings emphasise that doctor-patient commu-nication is a complex interactional system. To depictthis complexity, Street et al. (2007) applied an ecologicalmodel that takes into account the interplay of multiplephysician, patient and contextual factors that collectively influence doctor-patient interactions [ 56]. The influenceof any variable (e.g. ethnicity) may vary depending onthe presence of other factors (e.g., the patients level of education, income, doctors communication style) [ 53].The ecological approach recognizes that within the con-text of any medical encounter, a number of processesaffect the way physicians and patients communicate and

perceive one another. There are four important sourcesof potential influence: the physician s communicationstyle, patients characteristics, physician-patient demo-graphic concordance and the patients communication.First, how a physician communicates with a patient may depend on his or her style. Some physicians providemore information, ask more questions, are more sup-portive and use more partnership-building than otherphysicians [33,34,49]. Second, variability in physicians

communication and perceptions may be related to thepatients demographic characteristics (education,income, occupation) [ 57]. Finally, the patients commu-nication style can have a strong effect on physicianbehaviour and beliefs [ 18].

Important in this model is that patient interaction notonly depends on the physician s behaviour but also onpatients characteristics and preferences. Patients fromlower social classes more often suffer from (multiple)chronic conditions and more severe acute conditions[58]. But also they often have lower levels of health lit-eracy-the degree to which persons have the capacity toobtain, process and understand basic health informationand services needed to make appropriate health deci-sions [59,60]. Furthermore lower social class is asso-ciated with a lower sense of personal control also

known as external locus of control. This means that theperson perceives that certain events such as health andsickness are beyond his/her control [ 61]. This mightexplain why low SES people show lower levels of partici-pation. Also, because they are less used to or feel lesscapable to interact during consultation, they might pre-fer a more directive consultation style. Recently, aninternational consortium of research teams in the UK,the Netherlands, Italy and Belgium set up the Gulliverstudy which focuses on the patient s preferences in doc-tor-patient communication. Analysing a possible social

gradient in these preferences is hereby one of the pointsof attention of the researchers.

Limitations of the studyMany of the limitations the review of 2005 encounteredare still applicable today. Affective and non-verbal behaviour are important aspects in physician-patient commu-nication e.g. through their influence on patient satisfaction[44]. Still a limited number of studies described the inter-action between social class and non-verbal physician-patient communication. All studies indicates the difficul-ties measuring and coding non-verbal behaviour. There-fore, these limited number of studies entails importantmethodological difficulties and does not allow us to draw conclusions concerning non-verbal and affective behaviour. Further research on this topic is still needed.

Secondly, it is very difficult to compare the results of

the studies due to the great diversity of measurementsand frameworks organising these measurements in thedifferent studies. Socio-economic status of the patientwas measured by means of educational level, income oroccupation [ 3,62]. An alternative to determine SES is touse proxy measures e.g. the insurance status, housetenure, car ownership, socio-demographic measures(race, etc.). Articles using proxy-variables as the only measure for SES were excluded. However, some of theselected articles used these variables in combination witheducational level, income or occupational class. Next tothe SES of the patient, also communication variables canbe classified in many different ways. The variables usedin these classifications are not always comparable, mak-ing if very difficult to compare the studies using differentclassification systems. We chose to categorise most of thecommunication variables according to the axis verbal/non-verbal behaviour. The determinants of communica-tion that did not fit into the categories of this axis wererelated to patient centeredness.

In order to improve the comparability of futureresearch, the use of a uniform definition and classifica-tion of communication variables is indispensable.

Practice implications

This review of the literature has revealed the complexrelationship of doctor-patient communication and rein-forces the practice implications of the former review.Physicians behave differently with patients from differ-ent SES and patients communicate differently with theirdoctor depending on their SES. The finding that thephysician s communicative behaviour is related to thecommunicative style of the patient and to his/her perso-nal or social characteristics, may have important impli-cations for the daily practice of the physician.

Physicians need to be aware of the differences in giv-ing information to and involving patients from lower

social classes in the consultation, as well as of theunderlying causes [ 63]. It is important that physicianspay attention to the attitudes that they have towardpatients, and have to remain aware of how their feelingsmight impact their behaviour and thus be perceived by patients [ 64]. They should consider the possibility thatconscious or unconscious stereotyping may influencetheir behaviours, including their interpersonal style [ 65].Physicians have to encourage patients to discuss theirconcerns and to ask questions, and they should listenactively. Communication skills and attitudes training canbe an important tool to improve these defaults: theeffects of such training have been proven and can per-sist over time [ 66].

Patients have a certain power to control communica-tion during the consultation and to influence the physi-cians communicative behaviour. However, patients from

lower social classes seem to exercise this control lessthan patients from higher educated groups. It seemsthat not only patient s personal characteristics but moreimportantly their communicative behaviour has an influ-ence on the doctor-patient communication. Therefore itis important to empower the patients towards moreself-efficacy and towards learning how to express theirconcerns and preferences [ 33,34,38,67].

It has been shown that interventions to increase theparticipation of patients with low education obtain agood response and lead to measurable and clinically important improvements in health outcomes [ 68]. By understanding processes that facilitate or hinder patientinvolvement, physicians should be better able to adapttheir own communication and office practices to helppatients more effectively participate in medical encoun-ters [52].

On the other hand, it is important not to take patient-centered care as the obvious and only choice. Whenworking patient-centered, physicians should not only focus on normative thinking regarding participatory deci-sion making but they also have to pay greater attentionto a broader set of considerations relating to respect forpatients as individuals. It is important to enable andempower patients but it is perhaps even more important

to enable and empower them to the degree that they desire. As McKinstry states: Doctors need both commu-nication skills and time in consultations, along withknowledge of their patients, to determine at which times,with which illnesses, and at which level their patientswish to be involved in decision making [47].

Future research should further investigate low-SESpatients perceptions and expectations of their healthcare providers communication skills and of beinginvolved in the decision making process. Special attentionshould be paid to the relationship between patient skills,patient activism and communication satisfaction [ 50].
