For a medical test to be of value the patient needs to see a doctor

Among the commonest tests ordered by doctors is a full blood count. The test presents signs of iron deficiency anaemia. The prevalence of that condition is reported as follows:

In Australia in 2011–12, around 760,000 people aged 18 years and over (4.5%) were at risk of anaemia, with women more likely to be at risk than men (6.4% compared with 2.5%). The risk of anaemia was highest among older Australians, with rates rapidly increasing after the age of 65 years. People aged 75 years and older were more likely to be at risk of anaemia than all other Australians, with 16.0% in the at risk range compared with 3.6% of Australians aged less than 75 years. Australian Health Survey

With regard to this blood test (AACC):

  • Haemoglobin (Hb)—may be normal early in the disease but will decrease as anaemia worsens
  • Red blood cell indices—early on, the RBCs may be a normal size and colour (normocytic, normochromic) but as the anaemia progresses, the RBCs become smaller (microcytic) and paler (hypochromic) than normal.
    • Average size of RBCs (mean corpuscular volume, MCV)—decreased
    • Average amount of haemoglobin in RBCs (mean corpuscular haemoglobin, MCH)—decreased
    • Haemoglobin concentration (mean corpuscular haemoglobin concentration, MCHC)—decreased
    • Increased variation in the size of RBCs (red cell distribution width, RDW)
    • A guide to interpreting the test is here

Therefore among the pathognomonic features of established iron deficiency anaemia (IDA) is a low Mean Corpuscular Volume (MCV). The sensitivity and specificity of a low MCV for a diagnosis of iron deficiency anaemia are quoted as  42% and 93%. Assuming a prevalence of 3.6% in the under 75 year old age group this means that if 100 adults in Australia had a full blood count then 3-4 will have iron deficiency anaemia. Screening these people for IDA with this test 8.3% of people will be told they have an abnormal test i.e. 8 people. Of these only 1-2 will be a true positive for IDA. On the other hand 6-7 may be misled into thinking they might have iron deficiency. 91 will be told they have a normal test in this case 2 may be incorrectly reassured. Of course there are other significant conditions which present with a microcytosis ( low MCV) although ‘treatment’ is not necessary in many such cases and also screening for IDA involves other and more sensitive tests.

If the prevalence of the condition was 20%, then even the modest sensitivity and specificity of this test would identify more people at risk of IDA even though it will also miss people with the condition.

  • Number of people with positive test: 14, correctly identified: 8
  • Number of people with negative result: 86, incorrectly reassured: 11

In practice the sensitivity and specificity of tests may be assumed closer to 90% in each case. Given these figures the numbers of people from 100 people test and correctly identified, incorrectly reassured or told they are ill depends on the prevalence. The prevalence of most pathology in the community is low often well below 1%. The figures are presented in the infographic below.

Prevalence 0.005% ( 5 per 1000 people, e.g. hypothyroidism )  2% ( e.g. diabetes)  20% (e.g. common and plantar warts).

From these figures it can be seen that testing is more fruitful in circumstances in which the prevalence is high. The prevalence is higher in those who have signs and symptoms of a condition. One could argue therefore that the ‘prevalence’ is much higher in those who choose to consult a doctor as opposed to the ‘prevalence’ in the community.  For iron deficiency anaemia these circumstances are well known. Which means an effective consultation in which the patient is heard and examined is crucial to interpreting test results. As can be seen from the calculations there is a substantial risk of labelling people as ill, or requiring yet more tests given the modest prevalence of most conditions in the community and where there might be an indiscriminate use of tests.

It is hard to disagree with Campbell and colleagues who considered this issue and noted that:

1) Diagnosis is based on a combination of tests and clinical examination and there is little research based on the sensitivity and specificity of the combination of different examinations as opposed to a one-off test, which is why GPs are unlikely to know the values.

2) It is unclear what is meant by the prevalence of asthma or diabetes for these GPs. It is not the proportion of people in the population with the disease, but rather the proportion of people who come to consult who have the disease (perhaps with similar age and clinical history). This proportion is likely to be quite high and so the issue of overestimating the positive predictive value is less important.

3) The prevalence of the disease will also depend on the severity of the disease being tested for and so this also muddles the calculations.

We might however equally reasonably expect doctors to have an understanding of the issue if only because the practice of medicine involves the most crucial of ‘tests’ the history and the examination and this issue highlights the importance of that activity. Tests that are not appropriately interpreted can be harmful if only because they become a source of anxiety.

What are the limitations of the physical examination in practice?

 

The ideal innovation is inexpensive, readily incorporated into practice and has substantial patient benefits. In this context the humble physical examination is a strong candidate. However it is reported that in practice laboratory and or radiological tests are requested more often than not. Here is a quote from an editorial in the British Medical Journal (2009):

In the first camp are those who pine for the old days, bemoan the loss of clinical bedside diagnostic skills, and complain that no one knows Traube’s space or Kronig’s isthmus. In the second camp are those who say good riddance and point out that evidence based studies show that many physical signs are useless; some might even argue that examining the patient is just a waste of time. Verghese and Horwitz

Research suggests that most diagnoses are based on the history and examination:

In this prospective study of 80 medical outpatients ….in 61 patients (76%), the history led to the final diagnosis. The physical examination led to the diagnosis in 10 patients (12%), and the laboratory investigation led to the diagnosis in 9 patients (11%). The internists’ confidence in the correct diagnosis increased from 7.1 on a scale of 1 to 10 after the history to 8.2 after the physical examination and 9.3 after the laboratory investigation. These data support the concept that most diagnoses are made from the medical history. The results of physical examination and the laboratory investigation led to fewer diagnoses, but they were instrumental in excluding certain diagnostic possibilities and in increasing the physicians’ confidence in their diagnoses. Peterson et al

In only one of six patients in whom the physician was unable to make any diagnosis after taking the history and examining the patient did laboratory investigations lead to a positive diagnosis. BMJ 1975

Also the value of tests is contested in some cases:

Information from the history, physical examination, and routine procedures should be used in assessing the yield of a new test. As an example, the method is applied to the use of the treadmill exercise test in evaluating the prognosis of patients with suspected coronary artery disease. The treadmill test is shown to provide surprisingly little prognostic information beyond that obtained from basic clinical measurements. The JAMA network

A considerable number of plain abdominal films taken for patients with acute abdominal pain could be avoided by focusing on clinical variables relevant to the diagnosis of bowel obstruction. European Journal of Surgery

However the predictive value of the physical examination appears to depend on the clinical scenario. If the patient appears ill it is far more likely that they will have clinical signs:

In order to study the occurrence and positive predictive value of history and physical examination findings suggestive of serious illness in ill-appearing and well-appearing febrile children, 103 consecutive children aged ≤24 months with fever ≥38.3°C were evaluated from July 1, 1982 to Nov 24, 1982….The positive predictive values of abnormal physical examination findings for serious illness in ill-appearing (11 of 14, 79%) and well-appearing children (3 of 12, 25%) were significantly different (P = .02 by Fisher’s exact test). The trends for abnormal history findings in ill-appearing and well-appearing children were similar to those for abnormal physical examination findings but did not achieve statistical significance. The results, indicating an important interaction between a febrile child’s appearance and physical examination findings, are discussed in terms of probability reasoning in clinical decision making. McCarthy et al

In some common clinical scenarios it is difficult to find objective evidence in support of a diagnosis and tests are necessary. There are many examples including:

Irritable bowel syndrome

Individual symptoms have limited accuracy for diagnosing IBS in patients referred with lower gastrointestinal tract symptoms. The accuracy of the Manning criteria and Kruis scoring system were only modest. Despite strong advocacy for use of the Rome criteria, only the Rome I classification has been validated. Future research should concentrate on validating existing diagnostic criteria or developing more accurate ways of predicting a diagnosis of IBS without the need for investigation of the lower gastrointestinal tract. Ford et al

Heart Failure

Differences in clinical parameters in heart failure patients with decreased versus normal systolic function cannot predict systolic function in these patients, supporting recommendations that heart failure patients should undergo specialized testing to measure ventricular function. Thomas et al

Painful shoulder

Thirty one consecutive patients with a first flare of shoulder pain were prospectively included in the study. All had a physical examination performed by two blinded rheumatologists. Ultrasonographic examination was carried out within one week of the physical examination by a third rheumatologist experienced in this technique who had no knowledge of the clinical findings. Ultrasonography was considered the optimal diagnostic technique. Naredo et al

Also relevant are the physician’s skill in eliciting and interpreting signs:

Agreement between 24 physicians on the presence or absence of respiratory signs was investigated. The physicians were divided into six sets of 4; each set examined 4 patients with well-defined chest signs. There was generally poor agreement about particular signs. Overall, the 4 physicians in a set were in complete agreement only 55% of the time. Some signs such as wheezing seemed to be more reliably elicited than others such as whispering pectoriloquy. Comparison of diagnoses based on the clinical findings with the correct diagnoses supported by investigations showed that 28% of physicians’ diagnoses were incorrect. The more often the examiners differed from the majority on the presence or absence of a sign, the more likely they were to make an incorrect diagnosis.  The Lancet

In some cases physical signs are unreliable:

A review of published studies of patients suspected of having pneumonia reveals that there are no individual clinical findings, or combinations of findings, that can rule in the diagnosis of pneumonia for a patient suspected of having this illness. However, some studies have shown that the absence of any vital sign abnormalities or any abnormalities on chest auscultation substantially reduces the likelihood of pneumonia to a point where further diagnostic evaluation may be unnecessary. JAMA

Therefore always relying on physical signs without conducting tests is unsafe. However the value of the clinical examination as an integral part of the patient experience was eloquently articulated in the BMJ editorial:

A third view of the bedside examination, and one that we advocate, is that it is not just a means of data gathering and hypothesis generation and testing, but is a vital ritual, perhaps the ritual that defines the internist. Rituals are all about transformation. The elaborate rituals of weddings, funerals, or inaugurations of presidents are associated with visible transformation. When viewed in that fashion, the ritual of the bedside examination involves two people meeting in a special place (the hospital or clinic), wearing ritualised garments (patient gowns and white coats for the doctors) and with ritualised instruments, and most importantly, the patient undresses and allows the doctor to touch them. Disrobing and touching in any other context would be assault, but not as part of this ritual, which dates back to antiquity. Verghese and Horwitz

Common sense dictates that where the patient appears unwell the physical examination will have a higher yield. In those circumstances clinical examination is crucial:

Misdiagnosis of acute appendicitis is more likely to occur with patients who present atypically, are not thoroughly examined (as indexed by documentation of a rectal examination), are given IM narcotic pain medication and then discharged from the ED, are diagnosed as having gastroenteritis (despite the absence of the typical diagnostic criteria), and with patients who do not receive appropriate discharge or follow-up instructions. Rusnak et al

Therefore the physical examination has an incalculable value not necessarily obviating the need for tests but increasing patient satisfaction and reducing the risk of litigation. Click the link for an excellent video on examination.

Road map to better health outcomes

  • Improvements in healthcare outcomes warrant small changes. [Previous post].
  • Those best placed to know where and how to make those adjustments will change the future.
  • The most effective changes will trigger behaviours that we are already motivated and easily able to assimilate in practice.
  • The best interventions are those in which all concerned are rewarded in some way.

Such interventions:
1. Build on something the target is already doing. Anything that adds to workload or requires practitioners or indeed patients to do something significantly different in the course of going about their business is a waste of effort [example].
2. Need very few people to adopt them.  Ideas that require an orchestrated change in patient and or their general practitioner and or the specialist will disappoint [example].
3. Must be anchored by something that already occurs in practice. Practitioners routinely reach the point where they must agree or disagree with the patient and then do something.  An intervention that is anchored at that point is more likely to be assimilated in practice [example].
4. Can be incorporated into the habits or rituals of the target. Doctors vaccinate patients and patients regularly use their phones. Ideas that combine such aspects are likely to succeed [example].
5. Provide something the target wants. Interventions that are at odds with the target’s ideas, concerns or expectations are unlikely to succeed [example]. Interventions that speak to the target’s desires can be highly effective [example].

Small changes big impact in healthcare

According to the Royal College of General Practitioners, UK:

The consultation is at the heart of general practice… As a general practitioner, if you lack a clear understanding of what the consultation is, and how the successful consultation is achieved, you will fail your patients. RCGP

The impact of the consultation varies because of the different perspectives between doctors and their patients:

…. in the consultation the patient is most commonly construed as a purely “biomedical” entity—that is, a person with disconnected bodily symptoms, wanting a label for what is wrong and a prescription to put it right. Even under this guise the patient still sometimes fails to report their full biomedical agenda. Not all symptoms were reported and not all desires for a prescription were voiced. Barry et al BMJ

Much of what transpires in the consult is a ritual. Over the course of a professional lifetime most doctors will greet the patient in the same way, say the same sort of thing, prescribe similar drugs and order the same sorts of tests.  This occurs for a variety of reasons perhaps because a doctor learns to present herself and behave in a specific way but also because the doctor’s training and experience has a significant impact on their clinical practice. There is ample evidence that how doctors interact with their patients is crucial to the outcome of the consultation and ultimately to outcomes in healthcare:

An increasing body of work over the last 20 years has demonstrated the relationship between doctors’ non-verbal communication (in the form of eye-contact, head nods and gestures, position and tone of voice) with the following outcomes: patient satisfaction, patient understanding, physician detection of emotional distress, and physician malpractice claim history. Although more work needs to be done, there is now significant evidence that doctors need to pay considerable attention to their own non-verbal behavior. Silverman BJGP 2010

With this in mind, if you are a doctor you may want to consider seven components of your interaction with patients that warrant occasional re-evaluation:

What is the role of doctors in health promotion?

Our health is a cause for concern.

  • Over 1 in 5 Australians aged 18+ (22%) reported having Cardiovascular disease in 2011.
  • In 2009, the risk of being diagnosed with cancer before their 85th birthday was 1 in 2 for males and 1 in 3 for females.
  • 1 in 10 Australians aged 18+ (10%) had biomedical signs of chronic kidney disease in 2011–12, with the majority of these showing early signs of the disease.
  • 1 in 19 Australians (5.4%) had diabetes in 2011–12 (self–reported and measured data). This is includes approximately 1% of the population who did not self-report they had diabetes, which may indicate they were unaware they had the condition.
  • In 2007, 1 in 5 Australians aged 16–85 (20%) experienced a mental disorder in the previous 12 months.
    In 2013–14, 1 in 7 children aged 4–17 (14%) were assessed as having mental health disorders in the previous 12 months .
  • Over 1 in 4 Australians (28%) reported having arthritis and other musculoskeletal conditions in 2011–12. The most prevalent conditions were back problems, osteoarthritis, osteoporosis and rheumatoid arthritis.
  • 3 in 10 Australians aged 25–44 had untreated tooth decay in 2004–06.
  • 1 in 10 Australians (10%) reported having asthma in 2011–12. This rate is significantly lower than the rate of 11.6% in 2001.
    1 in 42 Australians (2.4%) reported having COPD in 2011–12. The development of COPD occurs over many years and mainly affects middle aged and older people.

It seems:

  • We eat too much. Almost 2 in 3 Australian adults (63%) are overweight or obese. 1 in 4 Australian children (25%) are overweight or obese.
  • We don’t take enough exercise. Based on estimates that between 60 and 70 per cent of the Australian population is sedentary, or has low levels of physical activity, it has been suggested that increasing participation in physical activity by 10 per cent would lead to opportunity cost savings of $258 million, with 37 per cent of savings arising in the health sector.
  • We drink too much alcohol and have been drinking more every year.
  • We don’t eat enough vegetables. In 2007–08, just over half of all children aged 5–7 years (57%) and a third of children aged 8–11 years (32%) ate the recommended amount of fruit and vegetables but only 5% of people aged 12–18 years and 6% of people 19 years and over did so.
  • Too few of us avail of cancer screening tests.
  • We drive too fast. Speeding is a factor in about one third of road fatalities in Australia. Additionally, more than 4100 people are injured in speed-related incidents each year.

Someone must be to blame for all this- if only they would do their job and tell us to eat and drink less, exercise more and slow down.  But wait there are industries profiting from our bad choices. We are influenced by more than our doctor. We have known this for decades. It is known as the Bronfenbrenner’s Ecological Model:

Hchokr

At the core of Bronfenbrenner’s ecological model is the child’s biological and psychological makeup, based on individual and genetic developmental history. This makeup continues to be affected and modified by the child’s immediate physical and social environment (microsystem) as well as interactions among the systems within the environment (mesosystems). Other broader social, political and economic conditions (exosystem) influence the structure and availability of microsystems and the manner in which they affect the child. Finally, social, political, and economic conditions are themselves influenced by the general beliefs and attitudes (macrosystems) shared by members of the society. Wikipedia

Most Australians (13 Million) spend over 18 hours a day online. One in every five minutes (3.6 hours) a day is spent on social media. On the other hand time spent with general practitioners (GPs) is declining:

The proportion of GPs providing ‘Level C’ consultations (longer than 20 minutes) is substantial (96%) and constant; however, the number of long consultations provided per GP decreased by 21% between 2006 and 2010. The proportion of GPs providing Level D consultations (longer than 40 minutes) decreased from 72% in 2006 to 62% in 2009, while the number of Level D consultations provided per GP decreased by 26%. AHHA

Secondly the number of problems presented to doctors in increasing. In one survey of the 8707 patients sampled from 290 GPs, approximately half (47.4%, 95% CI: 45.2–49.6) had two or more chronic conditions.

Junk food is cheap and readily available. It is advertised to children. Fresh fruit and vegetables are less available, more expensive and of poorer quality in rural and remote Australia. These areas are also among our most economically disadvantaged and residents generally have less disposable income to spend on expensive, healthier food options. According to one report a multinational fast food company paid $500 million in taxes to the Australian government and might be due to pay more.

A 2017 poll  found that most Australians (78 per cent) believe Australia has a drinking problem, 74 per cent believe our drinking habits will worsen over the next five to ten years, and a growing majority (81 per cent) think more should be done to reduce alcohol harm. A price increase of 10%  on alcohol has been shown to reduce consumption by an average of 5%. Similarly for every 10% increase in price, consumption of tobacco reduces by about 4%. Finally a significant proportion of people are unhappy at work and this has been associated with snacking and weight gain.

So it seems that we are choices are triggered by far more than a doctor informing us that we are making bad choices. Doctors can make a huge difference to the individual who seeks advice in a teachable moment and can be triggered to make better choices. This requires more time with the patient and a greater focus on the needs of that individual patient rather than the distraction of a public health agenda.  At a public health level doctors’ impact is miniscule because of the much more powerful and ubiquitous drivers of poor choices that are fueled by those who profit from our dubious behaviour.

What’s the shortest route to where you want to go?

As the conference season begins we note that response rates in the order of 10-20% are not unusual in primary care research. Hardly generalisable. And yet we need sustainable and workable solutions that will promote health and well being in an ageing demography with increasing multimorbidity. Researchers take note the traditional gatekeeper in primary care, the general practitioner is occupied just keeping up with demand. There is no time to recruit, to seek informed consent or to deliver interventions that are being tested in a traditional randomised trial. At one time membership of networks with ‘committed’, well meaning practitioners were considered essential to successful research. In 2017 relying on anyone or any organisation that purports to guarantee recruitment rates or ‘collaboration’ seems at best naive and at worst risky.

Health requires people to make different choices. Eat better, drink less, take more exercise, jettison bad habits, consider when and where to seek medical advice. The traditional model of healthcare is evolving. The evolution is driven by technology that has fundamentally changed our experience of many if not all things. People consider themselves more time poor than they ever were.

The ability to satisfy desires instantly also breeds impatience, fuelled by a nagging sense that one could be doing so much else. People visit websites less often if they are more than 250 milliseconds slower than a close competitor, according to research from Google. More than a fifth of internet users will abandon an online video if it takes longer than five seconds to load. When experiences can be calculated according to the utility of a millisecond, all seconds are more anxiously judged for their utility. The Economist

The lesson for those hunting for better ways to reach people is to consider the least that can be done to get there. The answer may be waiting in all of our pockets.

A cough is not minor in any sense

 

 Acute cough, which often follows an upper respiratory tract infection, may be initially disruptive but is usually self‐limiting and rarely needs significant medical intervention. Thorax

In adults or children with acute cough, the evidence does not support the effectiveness of over the counter preparations. Cochrane Review

On the other hand:

Oral syrups segment is expected to expand at 2.9% CAGR (Compound annual growth rate) over the estimated period and be valued more than US$ 10 Bn by the end of 2026. The segment is expected to create absolute $ opportunity of a little more than US$ 300 Mn in 2017 over 2016. The segment is the most acceptable dosage form for cough, cold, and sore throat medicines due to ease of administration and pleasant taste. The oral syrups segment dominated the global cold, cough and sore throat remedies market in terms of revenue in 2016 and the trend is projected to continue throughout the forecast period. Oral syrups segment is the most attractive segment, with attractiveness index of 1.5 over the forecast period. FMI

Cough, cough, cough. Every hour on the hour. There appears to be no end to it this season. No symptom is driving more people to seek treatment than the misery of upper respiratory tract infections (URTIs). The impact of the URTIs season on the population is massive as has been demonstrated in data from the US:

More than half (52%) of Americans reported that their cold impacted their daily life a fair amount to a lot. Productivity decreased by a mean 26.4%, and 44.5% of respondents reported work/school absenteeism (usually one to two days) during a cold. Overall, 93% of survey participants reported difficulty sleeping. Among all respondents, 57% reported cough or nasal congestion as the symptoms making sleep difficult. Drug Store News

One issue that appears to be bound up with the epidemic of URTIs is rates of prescribing of antibiotics. Here the available data are encouraging:

Professor Bell suggests that 20–25% of acute URTIs are likely to need antibiotics…..We have shown that over the last 13 years GPs in Australia have decreased their level of prescribing of antibiotics for acute URTI and to a lesser degree, for ‘other RTIs’. Britt et al

However there is an opportunity here over and above the treatment of an annoying self-limiting infection. Most people who seek help want more than anything else to feel better. By 2026 they will spend $10Bn in the attempt. The conversations in consulting rooms and pharmacies around the country focus on symptoms that will improve, eventually. Antibiotics won’t help. But, in the end what people want is to feel better not a lecture on virology. There is an opportunity for a ‘set play’.

Yes, you have a nasty infection and I see that it is making you miserable. Here’s what you can do to help your self.

There is an opportunity to forge a relationship with the patient. The ritual of the consultation complete with examination has the potential to create enormous deposit of social capital. Something that might be critical when the patient presents later in life with life-limiting pathology. There is the chance to understand a lot more about the patient for whom a cold is the final straw. But what’s the context? Be curious, very curious that’s why it’s called the art of medicine.

Healthcare will do better when Joe accepts that he is in trouble

There is nothing especially remarkable about Joe. At 49 he works as an administrator for a company in the city. He walks to work from the station having taken a train from the suburbs. He weighs 78Kgs and is 170cm tall (BMI 27). To stay that way he needs to consume no more than 1900 calories per day. He has a bowl of cereal for breakfast, a  panini sandwich for lunch and a home cooked dinner with a glass of wine. That’s about 1900 calories. Joe isn’t inspired at work but he earns a reasonable living. They bought a new car last year and Joe is tied to a hefty car loan, his wife Bridgette gave up her job as a nurse when they had their children ten years ago. They now have three children under 10. The youngest has asthma but he seems so much better since he was put on a steroid inhaler. Joe and Bridgette have had their ups and downs. They worry about money.  Mostly they work hard and are doing their best to raise their boys. At the weekend Joe goes to a football match but since his mid-twenties doesn’t play any sport. With the kids doing sport and music lessons there isn’t time. Joe has never smoked a cigarette.

During the week Joe goes for coffee with his colleagues at 10.30 every morning. He also enjoys a small muffin. Then he has a banana at 2 pm and a couple of small biscuits while he is watching television in the evening. He doesn’t think too much about it. He is consuming 500 calories more than he needs per day and in 6 months when Joe is 50 his BMI will put him over the line into obesity.

Joe rarely sees his doctor. In winter he occasionally gets a chesty cough and makes an emergency appointment with any doctor who is available because Bridgette says he might need an antibiotic. Once or twice since his thirties, a doctor checked his blood pressure and it is always normal. He had a medical as part of his mortgage application when he was 35 and everything was ‘normal’. Most of Joe’s friends are heavier than Joe and he still thinks of himself as ‘healthy’.  After all, he walks to work, has a healthy banana as a snack in the afternoon and he makes sure his evening meal is a healthy one.

Joe doesn’t see any problem. There is really time to talk to the doctor about why he likes that large cup of coffee and the muffin or to say that he is stuck in a dead-end job with a mortgage to pay and children to raise. Joe doesn’t admit that he is bored. The coffee break is the highlight of an otherwise long day of drudgery.  Joe’s trousers are getting a little bit tighter. Bridgette has noticed but his friends are all so much bigger and Joe doesn’t think she’s worried about it. She herself has gone up three dress sizes since the children were born so she doesn’t tease him too much. Besides, he just got a bigger size recently and he still thinks he looks good.

Joe is at risk of becoming a statistic in the epidemic of Globesity. All that stands in the way is the ingenuity and interest of those who care to find a way to help Joe turn things around.

She’s furious but what does your reaction say about you?

Where there is anger there is fear. Health issues are frightening. They pose a real and sometimes imminent threat to our basic needs. Sometimes even a threat to life itself.

There is a strong relationship between anger and fear. Anger is the fight part of the age-old fight-or-flight response to threat. Most animals respond to threat by either fighting or fleeing. But, we don’t always have the option to fight what threatens us. Instead, we have anger. Psychology 

Anger is an emotion that doctors encounter often. Unfortunately they may also find themselves getting annoyed at that angry patient who has been kept waiting, that angry mother who thinks her child’s test results should be available today, that angry young man who says he will be fired unless he gets a backdated certificate, that angry Boomer who is convinced her cancer can be cured if only this doctor arranges an appointment for coffee enemas.

Doctors can choose how to respond. How to interpret that emotion. Doctors too can be angry. Angry about having to work in a healthcare system where one sector doesn’t coordinate with another, a payment schedule that doesn’t reward for time spent waiting on the phone, a system where people come with undifferentiated problems and can’t give a clear history of their symptoms. They can choose whether or not to express this emotion during a heated conversation.

At the end of the day, doctors can go home- for the mother of the child with cystic fibrosis, the young man with the heartless employer, the old lady with bowel cancer there is no such escape. A response that may help is to acknowledge the anger but address the fear. It may even reduce the frequency with which people might see the doctor standing in the way of something they think will immediately reduce the threat. It may also help when doctors are angry that those who are the target of that anger confront the issues rather engage in recrimination.

Can the patient relay what was done for them?

A perennial source of dissatisfaction in healthcare (as documented here and here) is the poor flow of information from one sector to another. ‘Joe’ (speaking here– video from BMJ open) couldn’t tell me, his doctor, anything helpful about what had been done while he had been in hospital. That means we have to schedule several appointments to try to unpack it all. He was an in-patient for two weeks and someone had decided one Thursday morning that it was time for him to go home. It wasn’t really clear to Joe or to me why that particular morning or what was to happen when he got home other than that he should contact his ‘local GP’. A letter would follow some time in the future. There may have been good or bad reasons for sending him home. We could only guess what was in the mind of the person who made the decision:

We needed the bed. Joe was fine. His observations were normal, he was ambulant his wife was happy to take him home.

But of course Joe comes home with lots of questions, which I now struggle to answer without making phone calls to track down the busy medical team. The problem is articulated by several ‘stakeholders’ members of the ‘multidisciplinary team’ on the ward none of whom feel they own the problem of telling this man what he needs to know. There is only one constant in this story- Joe. If Joe can collect the information we need during the course of his hospital stay we might begin to improve the outcome:

In addition to increasing the burden on GPs, it engenders a need for a subsequent GP appointment; it limits GP capacity to respond to patient concerns and queries, at least on one occasion; it may result in a re-referral to the specialist; and it increases GP dissatisfaction with the care provided to the patient by the hospital.

The problem is Joe often does not know what he needs to know by the end of his hospital stay. It isn’t impossible to work out how to trigger questions for Joe to ask throughout his hospitalisation. What is far more difficult is to motivate every hospital ward and every discipline in a team to address this challenge consistently. It is ‘easier’ to nudge one individual than enlist the cooperation of the dozens of health professionals who will come into contact with Joe. Making people active in healthcare processes has achieved results before:

Influence at Work, a training and consultancy company that Cialdini founded, worked with the United Kingdom’s National Health Service (NHS) in a set of studies aimed at reducing the number of patients who fail to show up for medical appointments. They did this by simply making patients more involved in the appointment-making process, such as asking the patient to write down the details of the appointment themselves rather than simply receiving an appointment card.
