London's liaison psychiatry services: survey of service provision.

Aims and method To describe the liaison psychiatry services of all 30 general hospitals in Greater London and to determine whether services met national recommendations. The results were compared with a similar survey conducted 8 years previously to determine whether there had been significant service development. Results We identified wide variations in service provision across London. Fifteen hospitals (50%) had 24-hour services and one had no service. There had been a significant increase in services that assessed older adults. Increases in the size of teams and consultant psychiatry staff were not significant. Clinical implications Despite an increasing emphasis on the effectiveness of liaison psychiatry services, no London hospital had staffing levels consistent with national recommendations. Recent evidence for the cost-effectiveness of liaison psychiatry and an emphasis on parity between physical and mental health in National Health Service policy may provide further impetus for growth
