Strengths and limitations
A previous review by Beck et al mentioned that actual empirical data were relatively scarce.48 With the inclusion criteria used in this review, seven articles were found with a bearing on general practice.
This study has a potential cultural bias in interpreting and judging phenomena by standards inherent to European culture. General practice in Europe is most commonly delivered by GPs. In the US, primary care includes both general internists and paediatricians, as well as GPs.
A possible limitation of this review is the underexposure of ‘the danger of empathy’, such as a physician losing their professional distance, which, in certain situations, might make empathy a less desirable aspect of patient–physician communication.16,49
In focusing on empathy, the effects of contextual factors on specific health outcomes are possibly underexposed, such as intrinsic and/or extrinsic factors, healthcare setting, access to care, GP’s workload or pressure, and sociocultural factors.50
General limitations of this review are that only articles written in English are included. Furthermore, the existing measures of empathy have been taken as presented in the literature; no critical reflection of the validity of these measures has taken place.
Comparison with existing literature
The results of the studies seem to be supported by other authors. For patient satisfaction and adherence, Neumann et al,21 Kim et al,51 and Lelorain et al52 confirm the data; they found links between physician empathy and patient satisfaction, in various clinical settings. Mercer et al have shown that patients view quality of consultation in general practice as related to both the GP’s competence and the GP’s empathic care.53 Further, Neumann et al argue that affective-oriented effects of empathy are related to more satisfaction, adherence, and trust.16 Indirectly, patients who are more satisfied with the care received exercise greater adherence to agreed and recommended treatment regimens and courses of action.3
In relation to decrease of anxiety and distress, in experimental research in which a GP was trained in special communication styles, Verheul et al found that combining a warm and empathic communication style with raising positive expectations leads to positive effects on the patient’s anxiety.12
In relation to better diagnostics and clinical outcomes, authors have shown that empathic communication achieves the effect that patients talk more about their symptoms and concerns, enabling the physician to collect more detailed medical and psychosocial information. This leads to more accurate medical and psychosocial perception and ultimately to more accurate diagnosis and treatment regimens.13,22 Neumann et al based their ‘effect model of empathic communication in the clinical encounter’ on this evidence.16 It has also been mentioned that patients’ overall satisfaction with healthcare services, adherence to medical regimens, comprehension, and perception of a good personal relationship are positively related with interpersonal communication between the patient and care provider and are particularly related to the physician’s empathic behaviour.24,48,51,54,–,57 However, physician-perceived stress has also been shown to correlate negatively with enablement.57
Implications for practice and research
Empathy is a familiar term in the helping and caring literature. In 2008, the World Health Organization (WHO) reaffirmed the importance of primary health care with its report Primary Health Care Now More Than Ever.58 The key challenge was ‘to put people first, since good care is about people’.58 Rakel said that good medical care will continue to depend on care by concerned and compassionate family physicians who can communicate with patients, understand them, know their families, and see them as more than a case.59
Qualitative studies show that physicians link empathy to fidelity, prosocial behaviour, moral thinking, good communication, patient and professional satisfaction, good therapeutic relationships, fewer damage claims, good clinical outcomes, and building up a trusting relationship with the patient.15,24,25,60,61 In her study, Shapiro explored how primary care clinician-teachers actually attempt to convey empathy to medical students; they argued that the moral development of the GP, their basic willingness to help, their genuine interest in the other, and an emphasis on the other’s feelings are basic principles for acceptance of the empathic approach to the patient.25
In GPs’ views, limiting factors during consultation are: time pressure, heavy workload, a cynical view on the effectiveness of empathy, and a lack of skill.13,51,62 Neumann et al have shown that patients also see time pressure and busyness on the physician’s part as a limiting factor.21
Thus empathy can be seen as a part of patient–GP communication, characterised by feelings such as interest and recognition and the physician remaining objective. However, barriers exist for implementation in general practice.13,14,24,30,31,47,63,64
Another finding of this review is that some studies suggest that the degree of empathy shown by medical students declines over the course of their training.20,65,66 Empathy appears to increase during the first year of medical school, but decreases after the third year and remains low through the final year of medical school, measured using the Jefferson Scale of Physician Empathy–Student Version (JSPE-S).17,66,67 In the study by Hojat et al,66 there are no sex differences. On the other hand, Quince et al discovered that among males during medical education, in both the bachelor and clinical phases, affective empathy slightly but significantly declined and cognitive empathy was unchanged. Among females, neither affective nor cognitive empathy changed.68 It is ironic that there are indications that when students can finally begin doing the work they came to medical school to do (that is, taking care of patients) they seem to begin losing empathy.69 Possible explanations of the decline are: a lack of good role models and changes in general cultural and ethical views on illness, health, and portrayals of mankind. Interviews with physicians show that they think that, in current western society, it has become less a part of human nature to be interested in another person and to be affected by someone else’s misery.17 In their study of American college students, comparing the temporal changes between 1979 and 2009, Konrath et al showed that this development has social roots.65 Considering these possible tendencies in education and the above-mentioned technological changes within the healthcare system, which probably influence the patient–physician alliance negatively and could undermine empathy in these relationships, it makes sense to emphasise the results of the present review. The evidence of a correlation between empathy and clinical outcomes should be made widely known, especially among medical students and physicians. Some authors already believe empathy can be improved by targeted educational activities and they indicate opportunities to enhance empathy during education.16,17,26,38,69,–,71
It should be mentioned that, until now, the widely acclaimed benefits of empathy only have a small empirical base. Although a few studies of sufficiently high quality show promising results, much more research is needed to claim the effectiveness of empathy in clinical practice on evidence-based grounds. Neumann et al have already highlighted the need for an examination of the cost-effectiveness of empathy in the light of the recent focus of policy makers and health insurers on the efficiency of health care.16 It is a challenge to draw the attention of policy makers to empathy as an effective and efficient way of delivering health care. A vast majority of patients want empathic physicians, particularly, but not exclusively, in general practice.72 Indirectly, authors suppose empathic behaviour improves the physician–patient relationship and causes satisfaction for the patient but also for the physician,1,13,22 resulting in fewer cases of compassion fatigue or burn out.
Further research is needed on the practical use of empathy in general practice, with a focus on the effects and side effects of empathy and the expectations of patients and GPs. In this context, it is important to take account of how researchers have measured empathy. Measuring empathy is often based solely on self-reports and is therefore often remote from patients’ and physicians’ concrete feelings, experiences, and interpretations in practice. Only patient-perceived empathy is significantly related to patient outcomes. Therefore, it appears best to use a patient-perceived empathy scale to measure physician empathy in practice.47,48,63,65,73
It is remarkable that empirical studies on physician empathy are still relatively scarce. According to the results of the studies included in this systematic review, empathy is an important factor in patient satisfaction and adherence, in decreasing patients’ anxiety and distress, in better diagnostic and clinical outcomes, and in strengthening patient enablement. Thus, physician empathy seems to improve physical and psychosocial health outcomes.
