About 30% of people with long-term medical conditions experience anxiety or depression and those with co-morbid mental and physical health conditions have worse morbidity, mortality and use emergency services 2-3 times more than the general population (Kings Fund 2012). It is therefore essential that mental and physical healthcare is joined-up and this is often done through embedding clinical health psychologists within medical specialities in a collaborative model of care. This poster will describe such a model in West London in the UK covering conditions such as chronic pain, diabetes, heart failure and respiratory disease. All of these clinical health psychology teams show improved outcomes in depression, anxiety, quality of life and physical functioning unique to the medical condition treated, as well as reduced overall service utilisation. However, in addition to direct clinical input, clinical and counselling health psychologists widen their impact through indirect input into medical specialities - the value of which is often harder to capture but can be reflected in qualitative feedback, process measures and artefacts. Due to the different context and sub-culture of these medical specialties, embedded clinical and counselling health psychologists have to adapt and find different ways to ensure an integrated approach to care is offered to all patients in the specialty. This poster will explain the practicalities and challenges of integration on the ground, as well as the structures and processes that lead to better integrated care within each of the aforementioned specialties. This includes involvement in multi-disciplinary team meetings, multi-disciplinary group therapy, education on psychologically informed care, recognising psychology's value in improving rehabilitation adherence, routine screening, coproduction and staff wellbeing. Qualitative data from staff and patients will also be discussed which will help explain what matters most in driving truly integrated care and the importance of adapting to specific contexts.
