The Amber Spyglass (or what a retrospectoscope might look like)
Patients may see many doctors during the assessment and treatment of a particular illness. In the transition from primary to secondary care, medical opinion becomes more specialised, and the knowledge of the doctor facing the patient deepens in that particular area. Doctors become more confident in their opinion, and in the light of information are able to judge the quality of the decisions taken earlier on. This means that the specialist must, either privately or openly, pass judgement on what has gone before. Usually there is no controversy, because nothing incorrect was done. But sometimes, looking back, it becomes apparent that clues were missed. Things may have been done ‘sub-optimally’… according to the specialist’s very particular expectations.
The decision then has to be made – do you, as the specialist, tell the patient what you are thinking, or not?
The answer to this would seem simple. If by omission or commission the patient has been harmed, there is a responsibility to be open about it. However, harm is difficult to define, and the grey zone between delay and harm is broad. An abnormal blood test performed fifteen months ago might, if interpreted correctly, have led to an earlier diagnosis – but who can measure by what degree the patient’s life has been affected?
For the patient, finding out that two years ago a scan showed some early signs of liver damage, or that an abnormal vitamin level went unnoticed and uncorrected (contributing to months of fatigue), the conclusion is bound to be that things were not done well. The question of blame arises. The patient may ask – what do you think should have been done? What do you think about the quality of the care I received? Patients, in fact all people who receive a service from a professional, like to benchmark. It is natural.
It isn’t just at the transition between primary and secondary care that judgements on the quality of care may me made. On the wards, once a patient is established under the care of a specialist team, questions may be asked about the time it took to reach a diagnosis, or about the appropriateness of initial treatment. If the wrong diagnosis was reached (say, heart failure rather than chest infection), was the error acceptable? Was it just the way medicine works, with the correct diagnosis emerging over time, as pennies dropped and more experienced people made their assessment – or was it just bad medicine?
The temptation for doctors is to close ranks, and to present the hospital, or the health service as a whole, as a seamless unit where information comes in and decisions are made, by individuals yes, but by professionals who are part of a larger machine. Individuals shouldn’t be criticised; rather, blame the system.
I remember once, as a registrar, the family of a deteriorating patient asking me the name of the doctor they saw in casualty, who they felt did not diagnose the illness quickly enough. In the relatives’ room they pressed me hard, and demanded details. I felt that the presentation was complex, and that the quality of initial assessment had been satisfactory, if not genius. So I refused to give a name. I talked about the ‘team’. In my wisdom I felt that it could not help the situation to offer up an anxious SHO, and that the request reflected the family’s grief and uncertainty. The family needed a focus on which to direct their anger with the situation. Was I right or wrong?
On other occasions, in clinic, I have had to explain as best I can the decisions made by a doctor – often a GP – whom I have never met. I may end up saying things like, “Well, based on the information that was available eighteen months ago, it wasn’t unreasonable to monitor the situation…” Or, “Perhaps another doctor might have referred you six months earlier, if they had a special interest in this disease, but yet another might have waited a year. There is no right answer.” Or, if the patient asks me up-front whether I think their GP is any good, based on what has happened before, “It is not fair for me to pass judgement… I see patients with your problem nearly every day, and I come to this with a very specific expertise. Your GP has to decide when to refer… and it’s perfectly reasonable to monitor things for a while first.” I may say this even I think, privately, that they can’t have been that up to date with modern medical thinking on the topic in question. But who am I to criticise? What do I know about psychiatry or gynaecology?
So what drives this instinct to obfuscate? Is there a justification? Surely, in an era of transparency, the patient should know exactly what I am thinking.
It may be a desire to nip a potential complaint in the bud, even when I think a complaint (formal or informal) might be unjustified? If so, am I right to forestall what a more objective person might regard as a necessary corrective?
It may be loyalty to the larger medical community – an instinctive reflex to shield colleagues from criticism, just like in the relatives room on the ward all those years ago.
Or perhaps it is based on my acceptance that the practise of medicine will always involve variation in knowledge and in quality. Not every biochemical clue will result in the same decision. Each doctor will have developed their own store of knowledge, a unique bank of experiences and memories on which to base their decisions. As long as the decision was not clearly negligent, or so stupid as to warrant immediate correction, we are bound to let borderline or ‘sub-optimal’ decisions go without making a song and dance. We might hint in a letter back to the GP, or in a comment to a trainee’s supervisor, that next time a different decision should be made, and perhaps in that way we reassure ourselves that we have tried to improve the quality of the system as a whole. But patients are excluded from this feedback loop. They may go home entirely ignorant of the fact that things could have been done better, and may not read between the lines of the letter that they are copied into.
In modern medicine patient involvement is key, and transparency is a central pillar. We have a duty of candour which applies to identifiable errors of a certain gravity, and no doctor will overlook a pattern of behaviour that clearly puts patients at risk. But no such duty exists for reporting back on the grey cases where some educational improvement can be made. Is it reasonable not to inform patients in these circumstances? Would it help them? Or would it just cause confusion, and a loss of faith?
Over time I have become more honest about the non-scientific nature of medicine. Sometimes I begin a discussion with the patient with the papers spread out in front of me, or the blood results on the screen, and talk through what may or may not have been going on in their body over the last few years. If I think a spike in a liver enzyme might have been an early signal, which in retrospect was missed, I will tell them, but without loading it with an opinion. It’s just a fact. The ‘retrospectoscope’ can provide a false image of the circumstances that existed years before. Now you are here, let’s sort it out. There is no point in opining from the security of the specialist’s chair. Misdiagnoses are made there too.
In this way patients can begin to understand that the narrative of illness may follow numerous detours and diversions before the destination – a firm prognosis, a treatment plan – comes into view. Care is not homogenous, and variability, while sometimes permitting the occasional detour, is an inevitable result of human involvement.
