A Whole Systems Approach

A whole systems approach to the Community Mental Health Transformation   

Our work in six systems, an understanding of wider literature and our personal experiences have all contributed to the development of our thinking about a  whole systems approach to the Community Mental Health Framework (CMHF) and developing community mental health systems. Our whole systems approach aims to bring to life the most important connections to assist the people who are actively developing services and systems. The following are key and described in more detail below: 





Richard Byng discusses how the transformation process can be seen as a whole system.

Overarching themes 


A set of overarching themes have emerged that guide our approach. These are highlighted here. In part, this is in order to emphasise just how difficult CMHF transformation work is, but it is also to emphasise its potential to really make a difference:








Richard Byng discusses the need for a greater emphasis on a whole system approach to care, bringing in self-care and community.

The word system can have lots of meanings. We use it in two ways. Firstly we are thinking about the different teams which make up the system. The two figures below depict the mental health system before the CMHF, with significant gaps in care, and following investment, with new teams aiming to bridge gaps in care.

Secondly, we are using the word system to describe causal links between more abstract ideas such as individual journeys, collaborative leadership and flow rules. This approach is based on ‘systems theory’ and ‘complexity theory’. Things are connected, but unlike in many areas of physical science, causal links are not only complex but it is not possible to understand the whole system or to predict how changes to the system will affect care as provided. For those with responsibility for transforming system we have created a map, showing how we see the main links and influences operating across the whole system. It demonstrates how changes at an organisational level should be able to influence the balance of the whole system, in terms of outcomes for individuals, populations with inequalities and staff.

Individual Journeys

Key in the model is the individual and their journey through support.  People can be engaged in self-care and getting support from communities, and/or gaining support from services. Journeys can be experienced as timely and helpful or disjointed and difficult.


We have seen that system practices (care as it happens) are key to determining an individual’s journey through support. Additionally the system model (what has been agreed should happen), training, support and supervision and collaborative leadership activities each influence individual journeys. Service users will also influence these journeys – both through their varied responses to service offers and also based on their psychological state or social situation.

Naheen Ali reflects on the importance on focussing on the overall wellness of a person in the healthcare system, and how it feels to face fragmented care.

Arun was referred quickly by his GP and was called by the practice based mental health worker. He felt reassured and noticed the kindness in her voice. He was referred onto a team for people with ‘complex emotional needs’. He did not hear and wondered what this team might do. He missed their call and was away for a couple of weeks and then received a letter saying he had been discharged. This left him confused.

System Model

In each transforming system, different parts of the locality community mental health service offer come together in a more or less integrated way. And  how these parts of different sectors –  primary care or secondary care or voluntary community  - are designed to come together makes up the system model. This system model is the model as set up (and sometimes) described by local services and commissioners.

It incorporates adapted or new teams and roles as well as previously available and new interventions. It also includes what we call flow rules. Flow rules are the formal protocols for how individuals with mental health needs should move around the system to different practitioners and getting different interventions. These include what might be called pathways, eligibility criteria, etc, that define which team or practitioner should see which type of service user; also whether practitioners from one team are encouraged to liaise with practitioners from another and trust previous assessments - or start assessments again.  Some are deliberately flexible, others designed to be much tighter. Flow rules can also be informal, developed within teams without approval or endorsement from the leadership.


Clinical culture as found to be sometimes, but not always, formally part of the system model, agreed and promoted by system leaders. We use this term to include how risk for individuals is thought about, whether flexible decision making is endorsed (rather than prioritising protocolisation) and whether they promote diagnostic-based care or prefer person-centred or strengths-based approaches. Like flow rules, cultures of care can also be informal, emerging from past practices and current practice.


Additionally, there are organisational principles which may or may not be described explicitly. These include whether referral into mental health support is via a Single Point of Access (SPA) or whether practitioners are expected to refer to the team they think is most appropriate, and can be passed on seamlessly if needed (the no wrong door model). They also incldude whether proactive, as well as reactive care, is encouraged (e.g. for those with psychosis but not under specialist teams).


What we found is that most systems could describe the new teams, the practitioners, and key additional interventions, but many were less clear about the care culture and organisational principles that they had set up. Some systems did not have clear descriptions of what they wanted their system model to be – either for teams within the system or for the public.

See our Systems Model page for more details on these areas.

Neighbourhood teams have been a key part of some transforming systems. We might see that a system has been clear in their system model: that they want to receive all referrals (except to Talking Therapies/IAPT); that a ‘core team’ includes certain practitioners;  and that the weekly Neighbourhood Multi Disciplinary Team meetings also welcome GPs and VCSE staff. They might not however have specified that a social, as well as psychological model of care is being promoted.

System Practices

What we see when observing or being part of the system is a set of system practices. This is ‘care as it happens’ (in reality, rather than a model of what is wanted) and is what makes a difference to individual journeys. It may or may not correspond to the system model and, while influenced by the model, is very much affected by collaborative leadership and training, support and supervision.

In a system with a SPA, in order to carry out triage and initial assessment we might see the formal and detailed protocolised flow rules enacted ‘correctly’, but resulting in a series of procedures such as emails back and forth, internal waiting lists, initial telephone assessments, etc. This system practice might not lead to the care the system model had intended, with people dropping out along the way, waiting a significant time before being signposted out to community voluntary sector care or being passed on to specialist teams to carry out their own assessment.

In each system, we have seen how sets of meetings are developed for practitioners to make decisions both about care flow, and, to a lesser extent, to reflect on how the system model should be adapted.


Different balances of 1:1 encounters and group work have been put in place, with variable lengths of encounter, different roles, and different functions. Differences also exist in terms of mode of contact (telephone, video or face to face) and in the extent to which clinical contacts are about flow decisions, understanding an individual (doing an assessment) or providing support, care or therapy – or all of this together. 


Together these practices shape individuals’ experiences of gaining access, being passed around the system and being supported (or not) in their next steps. 

Supporting functions 


How the system model and the system practices develop are also seen to depend upon three key supporting functions across the system: 



We found that these functions were very varied across systems and that, while all our sites were making brave attempts to improve, this is an enormous endeavour and no one site had put everything in place. The CMHF transformation has a strong rationale as to how it will help individual service users and improve the work of staff, but it requires persistence and sharing of knowledge.

System outcomes and system balance 


The way in which individuals access services, get ongoing support or are supported back into self-care makes a difference not just to experiences, but to health and quality of life outcomes. Added together, these experiences and outcomes determine whole population outcomes, including mental health and wellbeing, and whether equality or inequality has been generated. Other system outcomes, including staff wellbeing and retention and whether or not there is a balanced budget, are also important.   


Some of these system outcomes can be monitored (budget, staff retention most easily), but measuring health outcomes is not straightforward.


Webinar 3 focuses on system balance and on how to evaluate and monitor to achieve an often-elusive system balance. 

Conclusions about system transformation


Systems are complex, with multiple factors interacting. Community mental health transformation is not a process that happens quickly – we believe it is likely to need 10 years of sustained effort. We observed evolving new practices being introduced alongside established structures and processes that are not necessarily disappearing.   


Some of the key ingredients appear to be:
