How “social” is your biopsychosocial model?

ResearchBlogging.org


It’s called the biopsychosocial model, but how much attention do we really pay to the social part of this model? While we know the medical model has its limitations (especially when we’re looking at how people respond to having health problems), in pain management I wonder whether we now have a ‘psychological’ model of pain rather than a biopsychosocial model?

The first time I started pondering this was when a large purchasing body in New Zealand removed the word ‘social’ from what is called a ‘Comprehensive Pain Assessment’. This is an assessment that has medical, functional and psychosocial components – but without the social part it seems to omit some of those really important aspects of the experience of both pain and disability…

I’ve pondered this issue of ‘social’ for a long time. What does it actually mean? There doesn’t appear to be a particularly clear definition of ‘social’ in the biopsychosocial model. I returned to Engel’s (1996) work on biopsychosocial model – and this is what he said: “As the name suggests, its intent is to provide a framework within which can be conceptualized and related as natural systems all the levels of organization pertinent to health and disease, from subatomic particles through molecules, cells, tissues, organs, organ systems, the person, the family, the community, the culture, and ultimately the biosphere.” He goes on to say “processes at the cellular level are subordinate to those at the tissue or organ level, which in turn are subordinate to those at the person or community level“.

Engel shows great compassion towards the people who seek help from the medical profession. He points out that the biomedical model is disease-oriented rather than patient-oriented, and that psychosocial is often thought to be “problems primarily of concern to the psychiatrist or the social worker.” By contrast, he states “For the patient the ultimate criteria [for wellness] are psychosocial, even when the complaint is physical. Patients’ criteria have to do with how one feels, how one functions, how one relates; with the ability to love, to work, to struggle, to seek options and to make choices. The physician, in contrast, while ostensibly attentive to such concerns, nonetheless is wont to consider such criteria as merely subjective… Even the organization of health care delivery is predicated on the assumption that the doctor, that is, the laboratory, is right and the patient is wrong.”

I couldn’t agree more when it comes to the way in which pain is conceived, especially pain where “the cause” can’t be found!

Engel’s vision was that “general competency for all health professionals would derive from their shared understanding that all three levels, biological, psychological and social, must be taken into account in every health care task.”  Not the ascendency of any one of the three.

What does the “social” consist of?  This diagram might help:

How often do you assess or report on roles and the changes that have occurred in a family as a result of the person you’re seeing having difficulty with their pain?  How often is their economic stress acknowledged? Their communication patterns identified?  What about the influence of the community – things like unemployment, the ways in which the Government or insurers fund various treatments or even income replacement/benefits, the actions of case managers, other health care providers, the effect of various policies on the individual?

Do we see these aspects of health as even relevant for health care?

My clinical focus has been on return to work for people who have persistent pain.  Sadly I’ve found that it’s often not even touched on in assessment or management – and if the person has lost a job, or feels they can’t return to work, the aim is not on how to help them feel more confident, but instead, on how quickly they can be pushed through a system that can ‘determine’ the kind of work they are physically fit for – as if physical fitness or capacity is the major determinant of return to work.

A more recent paper than Engel’s excellent theoretical one discusses the way in which members of chronic pain centres discuss their work. Harding and colleagues have published several papers from a qualitative study of people and clinicians in chronic pain centres. This paper refers to a study of 25 clinicians drawn from seven pain centres across the UK.

In the study, there was a very strong belief by all team members in the biopsychosocial model. They talked about it often, believed they were delivering a biopsychosocial model and backed each other up with regard to the importance of a biopsychosocial model. But – you knew there would be one! – did they use the entire model? In the assessment of Harding and colleagues, no. The majority of interventions were biomedical or psychological – the social got left behind.

One of their concluding comments is “pain clinic practitioners we interviewed readily embraced cognitive/behavioural based management strategies but reported relatively little if any consideration of the impact social factors played in managing chronic pain for patients failing to respond to interventions or for whom interventions were deemed appropriate.”

What would ‘consideration of the impact [of] social factors’ look like?
Well, recognising that most people with chronic pain will continue needing to interact with health care providers, I think learning how to be health literate – that is, learning what to ask about treatments, how to respond to suggestions, how to effectively and assertively interact with health professionals would be a good start.

I think it would be great if body language and those ‘illness behaviours’ or ‘pain behaviours’ that health providers notice were identified to the individual, and each person helped to review how much those behaviours influence how they are seen in the community. Even little things like the Mobility sticker on the car!

Communication skills, like assertiveness, would be useful. So would acknowledging changing roles and how the family adapt to the person coping with pain – and perhaps bringing some of those ‘invisible’ changes out into discussion, so families and individuals can decide what changes to hold onto, and those they want to review.

Looking at the impact of various labels, like ‘invalid’s benefit’ or ‘sickness benefit’, ‘disabled’ or ‘beneficiary’ or ‘compensation claimant’. And discussing the impact of systems that people interact with when they have chronic pain – like government agencies, or insurance agencies and the legal system.

The problem with doing this is – we start to step along a slightly more political path than we have traditionally had in healthcare. Once the effect of various systems is made clear, we can be sure that not everyone will like being made aware of this! Most notably, systems like insurance don’t tend to like having their systems critiqued – even when the critique is based on evidence. I’m not sure whether this is something we can ignore, though.


So – back to my original question: how “social” is your biopsychosocial model?
