Study Details

Study Description

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.

Arms and Interventions

Arm Intervention/Treatment
Placebo Comparator: Placebo

The placebo arm receives a placebo letter unrelated to Seroquel

Other: Placebo letter
The placebo letter describes a new rule in Medicare that requires prescribers to enroll in Medicare

Experimental: Informative Letter

The 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.

Other: Initial Informative letter
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.

Other: Followup Informative Letter
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.

Outcome Measures

Primary Outcome Measures

  1. 30-day equivalent prescribing of Seroquel treatments [9 months]

    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.

Secondary Outcome Measures

  1. 30-day equivalent prescribing of Seroquel treatments [3 months]

  2. 30-day equivalent prescribing of Seroquel treatments [6 months]

  3. 30-day equivalent prescribing of Seroquel treatments [1 year]
