[Modification of specialised care prescriptions by Primary Healthcare physicians]

To determine the percentage of new Specialist Healthcare prescriptions received and modified by Primary Healthcare physicians.

Descriptive, cross-sectional and multi-centre study with the participation of Primary Healthcare physicians from one Madrid Health Area during 2 months. A method was established for registering the origin of the new prescriptions in the Computerised Medical Record System. In order to register new prescriptions without any change from Specialist Healthcare, the «second level» option was marked when the prescription was issued. A protocol was prepared and was available on the Computerized Medical Record System, so for those cases where there was a new Specialist Healthcare prescription, the Primary Healthcare physician would not issue any prescription or issue a prescription with changes as regards the original one.

A total of 69 Primary Healthcare physicians from 15 Primary Healthcare centres registered 46,512 new prescriptions, 3,893 (8.4%) from Specialist Healthcare. From this number, 3,544 prescriptions (91.0% 95% CI: 90.1-91.9) were issued without changes, and 298 prescriptions were modified (7.7% 95% CI: 7.0-8.7). In 46 cases (1.2% 95% CI: 0.8-1.5) no prescription was issued. Some prescriptions were changed by 51% of Primary Healthcare physicians, and the median of prescriptions changed or not issued was 3. The main reason for the modification was replacement with generics.

A high percentage of new Specialist Healthcare prescriptions are issued without any changes being made by Primary Healthcare physicians. Modifications are concentrated in half of the participating physicians. Therefore, these data suggest that this practice is not generally adopted by the professionals.
