The Effect of Informative Letters on the Prescription and Receipt of Seroquel

The Effect of Informative Letters on the Prescription and Receipt of Seroquel

Abusive prescribing exposes patients to unnecessary health risks and results in wasteful public expenditures. This study will evaluate an innovative approach to fighting abusive prescription: sending letters to suspected inappropriate prescribers warning them that they are outliers compared to their peers and have been flagged for review. The study will target high prescribers of Seroquel (Quetiapine), an atypical antipsychotic. Using claims data, the investigators will assess the effect of the letters on prescribing of Seroquel, receipt of Seroquel by patients, substitution behavior by prescribers and patients, and health outcomes of patients.

• Outlier with respect to the count of Seroquel 30-day equivalent prescription drug treatments relative to peer group of prescribers in 2013 and 2014
