To ask the Scottish Executive how many reviews of NHS services, such as chronic pain and wheelchairs, have been carried out since 1990, showing the cost of each review.

Reviewing NHS services is a core function of the NHS in Scotland and the Scottish Executive Health Department and assessing, reconfiguring and modernising services for the benefit of patients is a continuous process. A great number of reviews have been undertaken since 1990, including those undertaken by previous administrations. Many of these were carried out at local level. The information requested is therefore not held centrally.
