Book Review: [ii] Health System Redesign - How to Make Health Care Person-Centered, Equitable, and Sustainable

Part 1 gets straight to the matter of "challenging the orthodoxy" with a two page introduction to complexity and health. Part 1 covers:

• systems sciences
• visualization of complex systems (Capra's vortex metaphor)
• understanding the co-existence of different degrees of complexity and their dynamics within complex adaptive organisations based on Kurtz and Snowden's Cynefin model.
• health as a "complex adaptive experiential state"

All four points here are very pertinent to where we are in health and healthcare (the book rightly stresses this differentiation) and current and ongoing 21st century issues. The use of Capra helps to distinguish scale and the levels inevitably existent, experienced, and described in health and healthcare systems.

If you are familiar with Hodges' model and the Cynefin model, then the answer is yes - seeing the Cynefin model did make me hoot. (I remember Dave Snowden's work from Plaxo and a presentation he did in Lancaster back in 2007). More importantly, part 1 introduces where the focus needs to be to facilitate change; on the core driver of the system, the system's long-term direction, a specific system view and the need for a solid grounding in theoretical and applied approaches. This is were the visual tools and producing a view - perspective are so important. Chapter 2 contrasts the simple scientific world view and the complex scientific. The reader is asked to consider numerous background points, from the colloquial meaning of complex/complexity to the scientific. How do the words 'complex' and 'complicated' differ? At small scale the result is greater certainty BUT loss of context, while at the large scale we find greater uncertainty AND loss of detail.

Figure 2.3 shows the key features of complex systems (also indicating the dynamics - '+' '-'):

• System boundaries
• Interconnectedness
• Feedback
• Impact of starting (initial) condition

Some of the figures point to their means of creation "The essence of systems thinking" (Figure 2.4) produced through Insightmaker. Sturmberg's seeks to ground the discussion too by reference to the everyday. Table 2.1 runs through how systems can be related to the experience of a 'Long day at work'. Addenda are put to immediate effect with a reference to a map of the history of complexity science; the philosophy of complex adaptive systems; and the complexity and difficult questions.

As already suggested Chapter 3 on the visualisation of complex adaptive systems had my attention. The vortex metaphor (Capra) seems trite on first encounter, but it works.* The four different ways to map a system:

1. Systems map
2. Influence map
3. Multiple case diagram
4. Sign graph diagram

are quite important as if you can take the explanations onboard you really will be on the way to fully understanding and utilising theoretical and applied approaches. The learning here is allied with understanding common system dynamic behaviours which are also illustrated and explained. Figure 3.4 shows the Cynefin framework, which is still in my head. The Cynefin model deals with the continua of:

• uncertain - certain
• non-linear - linear

• Contrasts - Learning and Teaching
• and four quadrants that combine what is complex, knowable or complicated, chaos, and known or obvious (simple). The three references here span 1996-2003.

At chapter 4 - I was worried - 'Defining Health' (now there's a task) but this is also interesting, rewarding and well placed. Core notions of health are tabled (4.1) from 1911 to 2007. Health is distinguished from dis-ease. I must follow up the footnote on p.59 Marja Jylhä and her framework of self-perception of health. 

The illustrations on pp.60-61 are frustrating.

Very!

Not because they shouldn't be there, but because they are a gift that remain (as far as I am aware) unrealised in respect of those of us working in the humanities. We still lack the visualisation tools that we need.

If I mention Figure 4.1 "The somato-psycho-socio-semiotic model of health" you will get the drift and overlap with Hodges' model. There is more with 4.2 on Attractors in Health and Illness and the system dynamics of health. The political attractor is missing (and its 'gravitational' impact) in this rendering, but the barriers to progress are also raised at the book's end. Given the topic of health, the text is not science light, with the physiology of health and disease also used to explain points, so we have, gene networks, the autonomic nervous system, the hypothalamic-pituitary-adrenal axis and bioenergetics in the mitochondrion. While not in-depth the potential application across external factors-personal experiences and internal mechanisms are demonstrated. The role of the patient, public and carers are central today and realised to various degree in theory, practice, management and policy. Self-rated health is briefly mentioned and with community health and health services utilisation this closes part 1.
