By 31 July 2008, Backlogs, the secure online pathology reporting service, had reported more than 30,000 cases requiring its attention.
These figures represent a large increase over the same period in 2007.
The company's services are tailored to providing an alternative to locum recruitment for NHS histopathology and cytology departments.
The remit of Backlogs is to work in partnership with the NHS, supporting laboratories as and when required.
Backlogs provides capacity to cover holidays, sickness, unexpected workloads and confidential duty of care reviews.
Its combination of a UK network of specialist consultant pathologists, secure online reporting, no binding contracts and a flat-fee-per-case tariff have been key to this growing demand, said Backlogs.
In most cases, hospital laboratories prefer to retain control of sample preparation, but Backlogs can work from prepared slides, blocks or wet tissue, with any laboratory work being carried out in CPA accredited facilities.
Medical couriers collect and redistribute cases that are assigned to appropriate specialists and reported directly online.
