Liaison psychiatry at Imperial College Healthcare NHS Trust is provided by partner trusts in London. This service offers psychiatry services alongside medical treatment.

As our Trust spans across two mental health trusts there are differences in the services we provide at St Mary’s Hospital, which is covered by Central and North West London NHS Foundation Trust, and Charing Cross, Hammersmith and Queen Charlotte’s & Chelsea hospitals, which come under West London Mental Health NHS Trust.

At St Mary’s Hospital, our service provides mental healthcare to people attending St Mary’s, whether they present to A&E, attend outpatient clinics, or are admitted to inpatient wards. We also offer a perinatal mental health service. We deal with the interface between physical and psychological health.

At Charing Cross, Hammersmith and St Mary’s hospitals, the Hammersmith & Fulham psychiatry liaison service offers mental health services to inpatients and patients at A&E, as well as patients referred to our specialist clinics by their hospital consultants or GPs.

Both of the liaison psychiatry services operating at our Trust have been accredited as excellent services by the Royal College of Psychiatrists. This means that patients, carers, frontline staff, commissioners, managers and regulators can be assured that our service is excellent and that staff are committed to improving care.

Conditions and treatments

As many as a quarter of people admitted to hospital with physical problems may have mental health issues, which can manifest themselves in many different ways.

The liaison psychiatry team offers assessment and psychological support for our patients within the general hospital. The importance of psychological factors is increasingly recognised at many stages on the patient journey. The liaison psychiatry team has expertise in both managing and advising medical teams on the management of their complex clinical problems. As a liaison psychiatry team we also offer assessment for those presenting to A&E with a mental health crisis.

Problems that may be referred to liaison psychiatry include:

  • Psychological reactions to physical illness
  • Deliberate self-harm
  • Medically unexplained symptoms 
  • Organic mental disorders: delirium and dementia
  • Alcohol and substance misuse
  • Mental illness related to childbirth
  • Diagnostic difficulties
  • Abnormal illness behaviour
  • Behavioural disturbance
  • Medico-legal decisions
  • Assessment of capacity to refuse medical treatment 
  • Psychosis
  • Mood disorders such as depression, mania or anxiety

We are happy to discuss cases with any clinician to establish whether a psychiatric assessment would be beneficial to a patient and their care. There are no specific test or investigations that we request. However a current mental state is beneficial, as well as any past medical and mental health history. Treatments are based on each individual case and will be discussed with patients and appropriate clinicians once treatment needs have been established.
