Work-related ill health in general practice, as reported to a UK-wide surveillance scheme.

GPs with training in occupational medicine report cases of work-related ill health and sickness absence to The Health and Occupation Reporting network in General Practice (THOR-GP) using an online webform. This report describes the data reported in 2006 and 2007. GPs mainly reported musculoskeletal disorders and mental ill-health. A much larger proportion of the mental ill-health cases were sickness-absence certified, making up 55.9% of the total days certified. Musculoskeletal disorders are the most frequently reported diagnoses of work-related ill health, but mental ill-health is responsible for most work-related sickness absence.
