Communicating with patients

chapter 16 Communicating with patients




THE PATIENT-CENTRED APPROACH


At around the same time that ‘The Progress of Medicine’ (see overleaf) was created, a number of clinicians began expressing similar concerns about the increasing disease-focus of modern medicine, and the corresponding decrease in attention to the patient as an individual. They began to articulate a different approach, one that did not ignore the great gains made in the scientific understanding, diagnosis and management of disease, but advocated an integration of all these advances with the individual patient’s experiences, beliefs, feelings, fears and expectations.13 They differentiated between disease and illness, disease being the ‘biological processes physicians use as an explanatory model for illness’,2 and illness being the patient’s experience of that physical or psychological disturbance.3,4 The disease describes the common features between patients with a particular disorder, and is therefore invaluable in establishing the pattern recognition required for effective diagnosis, prognostic predictions and treatment. However, the illness experience of each patient is unique, and encompasses the ‘real life’ complexity of the disorder, which often does not fit neatly into textbook descriptions or investigation results. Disregarding the illness can lead to the depersonalisation of medicine, and a disconnection between doctor and patient, with no shared understanding of the very nature of the problem, and the intent and aim of treatment.5 Medical historian Brian Hodges identifies a paradox: that by the middle of the twentieth century, when doctors were more able to offer hope of effective treatment, and even cure, than at any other time in history, patients were losing confidence in ‘traditional medicine’.6 This is not necessarily contradictory, if one considers that these scientific advances and the resultant increasing ability of doctors to effectively intervene shifted the focus to disease, with a gradual, inadvertent lessening in attention on and even respect for the illness experience. This is not to say that these doctors were uncaring, just that there was a mismatch between what patients were seeking and what doctors understood they were being asked to provide.


As general practitioners, we are often witness to the discordance between a patient’s complaint that a doctor did not listen or seemed uninterested and the comprehensive history and differential diagnoses detailed in the correspondence back to us. Usually this discordance represents a disease-focused consultation—the doctor has heard the parts of the story that fit the disease model, but has had selective deafness to the patient’s experiences that lie outside this construct or, at least, has not reflected back to the patient that they have heard and understood. Often these are the aspects of the story that are of most importance to the patient—the effect of the illness on their life, their fears, their struggles to make sense of the illness, its causation and prognosis. Of course, GPs are also susceptible to this ‘selective deafness’. The integration of both the disease and the illness experience improves our understanding of the disorder, and the patient, and subsequently our management options (see Fig 16.1). Hippocrates himself stressed the importance of considering both ‘what is common to every and particular to each case’.2



Initially described as the disease–illness model, the clinical approach outlined in Figure 16.1 became the foundation of patient-centredness, to contrast with a disease-centred approach. It grew out of real clinical experience in general practice / family medicine, rather than being developed in theoretical and academic circles and, as such, resonated with GPs and their clinical experiences. It now has a broader currency within other medical specialties, although some find the term ‘patient-centredness’ quite threatening, as it is wrongly assumed that its opposite is ‘doctor-centredness’, with the inference that a choice has to made between the doctor’s and the patient’s agendas, therefore implying that patient-centredness is akin to consumerist medicine rather than a relationship based on mutuality8 and a collaborative partnership.7 Patient-centredness does not mean ‘giving in’ to the patient: an overt exploration of the patient’s agenda allows an open discussion of their expectations, and a clear explanation for refusal, if required.





PROGRESS OF MEDICINE


The artwork, ‘Progress of Medicine’, by E. Fries, which graces the entrance to the medical building at the University of Melbourne, has always held a special significance for me, although the personal meaning has changed over the years. When I first entered the building as a newly accepted medical student, it represented the long tradition of healers, stretching back millennia, whose ranks I was about to join. This was both humbling and awe-inspiring.




In my middle student years, chock-full of education in the medical sciences such as biochemistry, microbiology, physiology and pharmacology, I gazed at the panels and wondered how my medical forebears had been able to practise without such detailed knowledge. The depiction of the Caesarean without anaesthetic, the surgery conducted in street clothes, were horribly fascinating. How many patients had died as a result of their medical care? How did patients survive despite it? Of course, the doctors and nurses were well-intentioned, and providing the best care they could within the limitations of the current knowledge, but how very limited that seemed. It also prompted me to wonder which of the knowledge I was accepting as part of my study would be regarded askance at some future time, much as ‘bleeding the patient’ is regarded today.




Later, I returned to the university as a senior lecturer, primarily to coordinate the teaching of communication and consulting skills. I was now a practising clinician. I stood again before the artwork which had formed the backdrop of my professional life. But now my eye was drawn to the last of the panels—depicting the modern era.




I had previously regarded this as a proper celebration and acknowledgement of the scientific advances which underpinned the current practice of medicine, many of which had been discovered and developed within the corridors around me. But now something else struck me, so forcibly that I wonder still at the intentions of the artist and the faculty fathers who had selected this piece as their prominent statement about healthcare at the building’s entrance. Were they, in fact, issuing a silent challenge to all who passed? For where was the patient? They have been pushed into the background by all the technology. Whereas in the previous panels, the patient was at the centre of everyone’s attention, the focus had now fundamentally shifted. And in their scientific white coats, the doctors appeared less as individuals, more depersonalised than in the earlier panels. Did this truly reflect the evolution of medicine?

A key component of patient-centredness is to negotiate a balance between physician authority and patient autonomy, to achieve an optimal outcome for all involved. In some consultations, such as those involving health promotion or motivational interviewing, the scales will tip more towards patient autonomy. In other consultations the doctor may need to take on more of the decision-making responsibility. An extreme example of this would be in an emergency situation, or when the patient’s decision-making capacity is impaired. Recognising patient autonomy does not mean handing over all responsibility for decision-making to the patient, but using both doctor and patient expertise to inform the process. While the doctor brings their medical expertise to the consultation, patients are experts on themselves, with invaluable insights and knowledge of their own health status. In fact, patients’ self-assessments of their health have been shown to be a more accurate predictor of their survival, in both the short term and the long term, than more ‘objective’ measures from physical examination or a wide range of investigations.8


Most doctors have a preferred position on the spectrum between total patient autonomy and total physician authority, and tend to attract patients, where there is choice, who match this position. Although not all patients want to be actively involved in decision-making, most want to understand the options and the reasoning behind decisions.9 This interplay of roles potentially fluctuates with every consultation, not just with individual patient characteristics, but also with the same patient, depending on the nature and stage of the illness and the available management options acceptable to both parties. The truly patient-centred practitioner needs to be flexible enough to modify their approach accordingly.


McWhinney thus described two of the major tasks of the consultation to be to understand both the disease and the illness, and to integrate both the doctor’s and the patient’s agendas.2 The patient’s beliefs, concerns, expectations and preferences are actively sought and openly addressed, and the doctor’s reasoning in considering these made clear. Discordance between the doctor’s and the patient’s explanatory understandings of illness leads to misunderstanding and poor outcomes.2 One only has to consider three common examples to recognise the potential for dissonance: the cultural differences in health beliefs and health-seeking behaviours; the increased general acceptance of alternative and complementary therapies, many of which have significantly different underlying explanatory models; and the use by patients of information of variable quality accessed from the internet. A patient-centred approach leads to a greater understanding of the patient’s reasons for seeking help, and addressing of the patient’s specific concerns.7 This approach is associated with higher patient satisfaction and compliance than if their agenda was never explored, and with a significant improvement in clinical outcomes.4,5,7,8,1013 Clinical competence also, not surprisingly, leads to patient satisfaction, although some studies have suggested that patients are unable to objectively assess technical competence except in glaring examples, and tend to infer it from the doctor’s interpersonal skills. Paling suggests that patient trust is a function of perceived competence and caring.14


Incorporating the patient’s agenda also has positive outcomes for doctors, such as more accurate, effective and efficient consultations, increased doctor satisfaction and decreased frustration.5,7,13 A patient-centred approach has been shown to positively correlate with such clinical measures as taking a reliable history, prescribing the correct medications and giving appropriate information.8


The concern of many doctors is that a patient-centred approach will mean longer consultations. Numerous studies have demonstrated little or no increase in the length of consultations,4,5,7,8,11 especially once practitioners have become adept in the skills. This is attributed to the improved efficiency of ascertaining, and therefore addressing, the patient’s agenda early in the consultation, and realistically establishing what can be achieved in the time available, which may include negotiating what would be better left to a future consultation. Levinson suggests that patients may feel subjectively that they have had enough time if there has been effective communication, rather than the consultation actually running longer.12 McWhinney proposed that even a longer consultation may be an effective investment of time in the long term, if it more accurately establishes the nature of the problem and mutually acceptable action plans, compared with a series of consultations where both doctor and patient struggle to establish shared understanding and common ground.2 Effective communication has been shown to decrease the need for follow-up appointments, as well as leading to fewer investigations and fewer referrals.7


An overt discussion of the two agendas, including the reasoning that underlies them, can help overcome an apparent conundrum in modern medicine. A solid body of research and literature supports a collaborative decision-making approach that respects patient autonomy. However, many doctors feel very exposed by the medico-legal implications of a patient taking a decision that subsequently leads to a negative outcome, for example by not following through a referral or investigation request. Identification of the patient’s agenda helps the doctor identify any discordance, and enables them to frame the consultation around the patient’s needs. Sharing the doctor’s thoughts involves the patient in problem solving, helps patients understand why the doctor is asking a particular question, performing a particular test or examination, or making a referral, and provides an opportunity for elaboration and clarification. When the doctor’s hypothesis forming and testing occurs internally, patients may not be able to distinguish between a suggestion, which they may choose to follow or not, and an imperative, or appreciate the intended urgency.


Poor doctor–patient communication is a leading factor in 70% of litigation, particularly when patients feel deserted, that their views are devalued or not understood, or that the information they receive is delivered poorly.12,15 Doctors who explicitly negotiate the structure and expectations of the consultation with their patients are less likely to be sued.7


The process of negotiating an integration of both agendas can help develop a stronger doctor–patient relationship, which can be therapeutic in itself.8 It conveys the doctor’s interest and respect for the individual patient, and enables the patient to ‘tell their story’, which is a fundamental human need, particularly at a time of anxiety and uncertainty such as when confronting illness.8 As well as being cathartic, in finding the words to describe their situation to the doctor, the patient can make more sense of it themselves, and perhaps develop insights and new awareness.8 Stories change in the telling, greatly influenced by the responses of the audience, and in this way we help shape—consciously or unconsciously, for better or worse—the patient’s understanding of their illness experience.


McWhinney stated that the greatest single problem in clinical interviewing is the failure to let the patient tell their story.2 In a frequently cited 1984 study, Beckman and Frankel demonstrated that in only 23% of consultations was the patient able to complete their response to the opening question, and that most doctors interrupted after 15–18 seconds.16 The longest any patient took to complete their story uninterrupted was 2½ minutes, with most completed by 45 seconds. Of particular note was the observation that the patients’ most clinically significant concerns were often raised later in their story—they ‘built up’ to them, often establishing the context initially. Directing the consultation to the earliest issues will mean that these other, more significant concerns will either not be raised at all, or raised much later in a consultation that has already been spent on less important or urgent issues. This leads to poor time management and both patient and doctor frustration.8 Of course, trying to establish all the patient’s agenda at the outset is not fail-safe, and many patients need time to develop the relationship, trust and confidence through the consultation to raise their most significant concerns, particularly if they are embarrassed or fearful.


Thus, the tasks of the consultation go beyond making an accurate and comprehensive diagnosis/diagnoses, and formulating an appropriate management plan. They include understanding the patient and their illness and agenda, establishing and maintaining a collaborative relationship based on mutual trust and respect, appropriately shared decision-making, patient education and managing time and resources effectively. Communication skills are the tools that allow these tasks to be met.



COMMUNICATION SKILLS


Silverman and colleagues assert that the four essential components of clinical competence are knowledge, skills in communication, physical examination and problem solving.5,7 Communication skills are important not just for the interpersonal aspects of our work, but equally for the ‘technical’ tasks.8 Medical knowledge, physical examination and problem-solving skills are only useful if we can apply them, and for this we need to be able to take a relevant history, explain the reasons for examinations and investigations and ensure that the patient is giving informed consent, elucidate our diagnoses and management, and share our conclusions. This includes communication with our colleagues and other members of the healthcare team.


Effective communication is a clinical skill that can be learned.2,4,5,7,8,17 Communication skills do not depend on personality traits, and are not just about being ‘nice’ to patients. Certainly, they can be misused if the intent is not in the patient’s best interest and based on respect and positive regard. Although with practice they will become almost second nature, their use is still deliberate, and their selection based on the desired outcome. Until the doctor is practised and adept, they might feel forced, and sometimes their use will not be smooth; however, patients will usually still respond to the underlying intent, and forgive the occasional rough spot or back-tracking.


Different skills are usually required at different stages of the consultation, and this provides a useful structure for discussing them. Silverman and colleagues7 provide a detailed description of the structure of a typical medical consultation that incorporates a patient-centred approach, and identify the main tasks of each stage. Box 16.1 provides a summary of their framework.
