Brief Summary
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.

Conditions
Outcome Measures
Primary Outcomes (1)
30-day equivalent prescribing of Seroquel treatments
The prescribing of Seroquel over the 9 months following the initial sending of the letters. Prescribing is defined as the total "days supply" of Seroquel attributed to the prescriber, expressed in "30-day equivalents" i.e. divided by 30.
9 months
Secondary Outcomes (3)
30-day equivalent prescribing of Seroquel treatments
3 months
30-day equivalent prescribing of Seroquel treatments
6 months
30-day equivalent prescribing of Seroquel treatments
1 year
Study Arms (2)
Placebo
PLACEBO COMPARATORThe placebo arm receives a placebo letter unrelated to Seroquel
Informative Letter
EXPERIMENTALThe interventional arm prescribers receive an initial informative letter (called a comparative billing report or peer activity report) followed by 2 followup informative letters at approximately 3 month intervals.
Interventions
The placebo letter describes a new rule in Medicare that requires prescribers to enroll in Medicare
The intervention is a letter that describes the Seroquel prescribing activity of the individual in comparison to a peer group of similar prescribers. It highlights the fact that the prescriber's activity is highly unlike her peers.
The followup informative letter is identical to the initial informative letter except it provides an update on more recent prescribing rather than a description of earlier prescribing.
