IMPRESS breathlessness resources

New practical resources for clinicians, patients and public health on the prevalence and incidence of long term breathlessness in adults, including an algorithm for assessment, IMPRESS breathlessness Tips (BITs) for clinicians, patients and, to follow, researchers and commissioners. Draws together evidence and experience on COPD, heart failure, anxiety, obesity and anaemia.

You may need to join the Network to see the resources.  Alternatively, find them here:   and also our previous work Impressions 28 relative value of COPD.


Following on from our groundbreaking work that analysed the relative value of interventions for a COPD population, IMPRESS decided to take on a new value project. It decided to work with the London School of Economics again to apply the same STAR methodology to identify the relative value of interventions for a common symptom that matters to patients. We hypothesised that a symptom-based approach would:

  • Be a more patient-focused approach than a disease-based approach

  • Be more aligned to a holistic patient-centred approach

  • Introduce multiple morbidities into the discussions

  • Engage a wider range of clinicians from more than one specialty

  • Take everyone “out of the box” and therefore potentially lead to innovative thinking about how best to practise population medicine and achieve the greatest health gain/improvement in health outcomes

  • Answer some of the questions that commissioners are already asking about the right balance of generic and disease-specific services for people with long term conditions and how best to address the issues of comorbidities where, for example, it has been estimated only 14-18% of people with COPD only have COPD and when actively assessed for co-morbidities it may be as low as 3%.

    There were a number of common respiratory symptoms that we could have chosen, but we decided that the one that is a high priority on patient agendas, is closest to our previous work and sufficiently prevalent in the population to warrant a service, was long term daily disabling breathlessness in adults.

    The few epidemiological studies available seem to point in the direction that long term/chronic breathlessness affects about 10% of the general population, but the magnitude of the problem is greater in specific groups of the population, such as the elderly with about 30% of them being breathless. Despite these significant prevalence rates, breathlessness is mentioned as a reason for encounter in primary care in about 1% of the recorded consultations in general practice. Whether this figure is affected by coding behaviour in primary care or under-reporting of the symptom by patients is for discussion.

We have produced a summary of our conclusions in the form of BITs: Breathlessness IMPRESS tips. There are:

BITs for patients,

BITs clinicians,

BITs for commissioners

BITs for researchers

 

It has been an intellectually challenging piece of work. The cost-effectiveness evidence-base that we found for COPD does not exist for chronic and disabling breathlessness and therefore there is significant uncertainty. We needed to agree on a definition of breathlessness, identify the main underlying causes and bring together prevalence and incidence data for these causes: COPD, uncontrolled asthma, heart failure, anaemia, and obesity, singly or in combination and with or without anxiety, and distinguish between chronic and acute breathlessness. It seems as though some basic truths have been “blind-spots” in the research literature. For example, most patients and clinicians would say that breathlessness is a relatively common symptom for obese people (a belief also confirmed by the epidemiological data available, which show that about 50% of obese patients are breathless and up to 70% of obese elderly complain of some degree of breathlessness) and yet the recent excellent Royal College of Physicians Action on Obesity report has one mention and no discussion of breathlessness.  In heart failure breathlessness may not be the cardinal symptom, which might be tiredness, however, the literature suggests up to 93% of people with heart failure, mainly elderly, suffer from breathlessness. The sensation may be perceived by the individual as part of their normal ageing process. We had many debates about when breathlessness is disabling and warrants an intervention and what that intervention should be.

The interaction between breathlessness and anxiety is complex and so this is another reason why this project has been worth doing, because it forces discussions about the interaction between mental and physical health and highlights the need for healthcare professionals to have skills to promote both. For example, panic disorder is ten times more common in the population with COPD than in the general population. However, anxiety is under-diagnosed and under- treated in primary care despite strong evidence of the effectiveness of talking therapies.

There are few straightforward answers when you combine general practice, community and hospital clinicians from different specialties and disciplines to reach consensus about coding, symptom-scoring, patient and population interventions though much learning. It is also challenging when you bring together literature from medicine, psychology, and public health. There are also few examples of symptom-based services in operation and even fewer examples of how these are commissioned; that is, how they are paid for or monitored. However, we have reached some conclusions that could make a difference today to people with chronic and disabling breathlessness. We also have a reasonably long list of research questions that we encourage academic health science networks to investigate. We see this as the beginning of a debate about how to best set up a breathlessness service for a population. We welcome feedback, examples of good practice, and case studies and urge those setting up services to evaluate their cost and their outcomes, and to publish their findings.

One of our conclusions is that local breathlessness services and pathways will need to grow from what already exists provided by health and local authorities, and also will depend on the local populations’ needs and health status. Disabling breathlessness is more common in deprived populations. Therefore we would encourage the local stakeholders involved in developing, approving and implementing joint strategic needs assessments to use our work as the basis for a local (and ultimately electronic) version.

What is certain is that the service will need to integrate mental and physical health pathways and services, and a common and consistent approach to behaviour change across a number of health specialties and public health. It is also certain that the normal consultation arrangements are not fit for purpose to assess a breathless person. We strongly recommend that services review the tests of change that a number of areas are undertaking to provide longer appointments in long term conditions in both primary and out-patients settings. We also want to reinforce the power of taking time with the patient to take a full history, once the immediate decision about whether to admit a patient has been made. At an individual level, always be mindful of three dimensions: the person’s mental health, their social context as well as their physical health, remember that breathlessness is not always caused by one single factor and that all breathlessness is stressful to some extent; the question is to what extent.

Postscript: Lambeth and Southwark CCGs have now adopted an adapted version of the algorithm for local use using EMIS Web.
