Medication dependency and physician's role

The administration of benzodiazepines in suicidal, anxious, or agitated patients with depression is common international practice. Nevertheless, the prescription of BZDs is recommended to be limited to a period of a few weeks. There are several epidemiological studies about the situation in Germany, but many questions are still unanswered. The BfArM sought a new method to track prescription of medications with the risk to induce dependency. The present article describes the methodology and the early results of the pilot study. As a new approach, data from a processing center for pharmacies were used; patient-years, a risk scale with six steps, and diazepam-equivalence dose instead of defined daily dose were used for the analysis. About 35% of prescriptions were long-term treatment. Even if several physicians prescribe the medication, the main physician prescribing the medication can identify the risk level of the patient in 80-90% of cases.
