A high proportion of patients in general hospitals have co-morbid mental health problems, often leading to poorer health outcomes and increased healthcare costs. For example:
- The effects of psychological morbidity in patients with chronic obstructive pulmonary disease are associated with increased lengths of stay in hospital (1) and increased out-patients attendance (2) .
- Evidence shows that people with severe mental illness, including depression, have a 2–3 fold increased mortality rate compared to the general population which is not only caused by increased suicide but is associated with physical illness (3).
- High proportions of people with physical health conditions also have co-morbid mental health problems, this includes 30-65% of medical in-patients (4)
A recently completed service evaluation (5) shows that an effective liaison psychiatry service that rapidly assesses such patients is likely to improve their health outcomes, as well as saving money through:
- More effective “diversion and discharge” of patients seen in Accident and Emergency Units to more appropriate service, and early but effective discharge from general admission wards
- Quicker discharge from hospital and fewer re-admissions, resulting in reduced numbers of in-patient bed-days.
- The integration or “interface” of a comprehensive range of mental health expertise within an acute general healthcare setting, with a target for response time being one hour.
