Gaps between paediatric and psychiatric surveillance systems: rates of reporting in joint studies.

Aims and method: The British Paediatric Surveillance Unit of the UK Royal College of Paediatrics and Child Health contacts participating consultant paediatricians each month to survey whether particular rare conditions or events have been seen in their services. This national surveillance of rare paediatric events has allowed a large amount of research into multiple paediatric conditions. In 2009, the Royal College of Psychiatrists established a similar system - the Child and Adolescent Psychiatry Surveillance System (CAPSS) - to survey consultant psychiatrists in UK and Ireland. Since many conditions involve mental and physical health features, seven studies have been run using reporting to both systems, with simultaneous surveillance across both paediatricians and psychiatrists. Given the desire by policymakers, commissioners and clinicians for well-integrated physical and mental healthcare ('joined-up working'), and if the surveillance systems were functioning well, the CAPSS Executive expected high rates of parallel reporting of individual patients to the two systems. The current study synthesises the rates of parallel reporting of cases to those two systems. We assimilate rates of parallel reporting across the seven studies using figures that have already been published, and by contacting contributing research groups directly where the relevant figures are not currently published. No new primary data were collected.

Results: Of the 1211 confirmed cases, 47 (3.9%) were reported by both psychiatrists and paediatricians. No parallel reporting occurred in four of the seven studies.

Clinical implications: Our findings raise questions about whether joined-up working in mental and physical healthcare is happening in practice. Research into challenges to obtaining comprehensive surveillance will help epidemiologists improve their use of surveillance and control for biases.
