Frequently Asked Questions
Liaison psychiatrists are particularly effective in personal injury cases where a claimant has suffered significant physical trauma. They assess how the physical injuries, medical treatments, and hospitalisation have caused or exacerbated psychiatric conditions like PTSD, depression, or Somatic Symptom Disorder.
Yes. This is a core part of their clinical work. They assess whether a patient has the capacity to consent to or refuse medical procedures, surgery, or complex treatments, especially when the patient is currently in a general hospital setting.
While both are trained in adult psychiatry, a liaison psychiatrist has specific expertise and additional training in the “interface” between physical and mental health. They are accustomed to working in acute hospital wards, intensive care units, and A&E, and have a deeper understanding of how physical diseases and medications affect mental state.
Absolutely. Liaison psychiatrists are the primary experts for delirium and intensive care-related psychiatric issues. They can review medical records to determine if delirium was correctly diagnosed and managed, which is often a critical factor in clinical negligence claims.
Yes, where necessary. If a patient is currently hospitalised, our experts can attend the hospital for a bedside assessment. Alternatively, if the patient has been discharged, assessments can be conducted at one of our consulting rooms or via secure video link.
