The Grampian Asthma Scheme for integrated care : an evaluation of its effect on the care of adult asthma patients in the community
The aim of the study was to estimate the effect of the GRampian ASthma Study of Integrated Care [GRASSIC] (for adult asthma patients currently attending hospital clinics) on the care of those patients not attending outpatient clinics. In order to do so, a method was devised for identifying random samples of adult asthma patients treated by general practitioners, using GP10 prescription forms. A two-phase postal and interview survey was carried out in Grampian, where the changes in clinic care were introduced, and Highland, where no changes were planned. Responses to the first postal questionnaire (in 1989), at the start of GRASSIC, were received from 1054 patients (728 from Grampian and 326 from Highland), and 1138 replies to the second (in 1991) (792 from Grampian and 346 from Highland). Interviews were carried out with a subset of 50 patients in Aberdeen and 25 in Inverness, after each postal survey. Detailed analysis of the responses demonstrated that GRASSIC did not have an effect on those patients not attending an outpatient clinic. However, changes in the care of patients treated in the community occurred over the two year period of the study.
