Allergic conditions: primary care data

Table 1 shows data from the Practice Team Information (PTI) programme. This provides national estimates of prevalence and incidence of various conditions, based on records of consultations with members of the primary care team at a representative sample of Scottish practices. These figures may underestimate the true prevalence and incidence because they include only those people who have consulted for the specific problem during the time period under consideration, and do not include those who manage their own condition.

* Conditions are based on Read codes. These figures use the Read code groupings used by PTI prior to November 2005. Figures consistent with those in PTI's November 2005 data release will be added to this site shortly. Estimated numbers are rounded to the nearest 50. Estimated numbers and rates are standardised for age, sex and deprivation.
