Performance Measure Name: Patients discharged on multiple antipsychotic medications

Description: Patients discharged from a hospital-based inpatient psychiatric setting on two or more antipsychotic medications

Rationale: Research studies have found that 4-35% of outpatients and 30-50% of inpatients treated with an antipsychotic medication concurrently received 2 or more antipsychotics (Covell, Jackson, Evans, & Essock, 2002; Ganguly, Kotzan, Miller, Kennedy, & Martin, 2004; Gilmer, Dolder, Folsom, Mastin, & Jeste, 2007; Kreyenbuhl, Valenstein, McCarthy, Ganocyz, & Blow, 2006; Stahl & Grady, 2004). One study reported 4.6% of patients concurrently received 3 or more antipsychotics (Jaffe & Levine, 2003). These findings are seen across diverse sectors: state mental health authorities, the Veterans Health System and Medicaid-financed care. Antipsychotic polypharmacy can lead to greater side effects, often without improving clinical outcomes (Ananth, Parameswaran, & Gunatilake, 2004; Stahl & Grady, 2004). As a result, a range of stakeholders have called for efforts to reduce unnecessary use of multiple antipsychotics (Centorrino, Gören, Hennen, Salvatore, Kelleher, & Baldessarini, 2004; Gilmer, Dolder, Folsom, Mastin, & Jeste, 2007; National Association of State Mental Health Program Directors, 2001; University HealthSystem Consortium, 2006). Practice guidelines recommend the use of a second antipsychotic only after multiple trials of a single antipsychotic have proven inadequate (American Psychiatric Association [APA] Practice Guidelines, 2004). Randomized controlled trials (RCTs) provide some evidence to support augmentation with a second antipsychotic in treatment resistant patients. Most of these studies were limited to augmentation of clozapine with another second-generation antipsychotic (Tranulis, Skalli, Lalonde, & Nicole, 2008). Among patients without a documented history of previous treatment failures of antipsychotic monotherapy, multiple RCTs and other controlled trials failed to show a benefit of antipsychotic polypharmacy over monotherapy (Ananth, Parameswaran, & Gunatilake, 2004; Centorrino, Gören, Hennen, Salvatore, Kelleher, & Baldessarini, 2004; Potkin, Thyrum, Alva, Bera, Yeh, & Arvanitis, 2002; Shim et al., 2007; Stahl,& Grady, 2004). Clinical circumstances, such as shorter inpatient stays, may require hospitals to discharge a patient on multiple antipsychotics with an aftercare plan to transition to monotherapy. In such cases, effective communication between the inpatient and aftercare clinician is an essential element of care.

Type of Measure: Process

Improvement Noted As: Decrease in the rate

Numerator Statement: Psychiatric inpatients discharged on two or more routinely scheduled antipsychotic medications
Included Populations: Not applicable

Excluded Populations: None

Data Elements:

Denominator Statement: Psychiatric inpatient discharges

Included Populations:
  • Patients with ICD-9-CM Principal or Other Diagnosis Codes for Mental Disorders as defined in Appendix A, Table 10.1 discharged on one or more routinely scheduled antipsychotic medications (refer to Appendix B, Table 10.0- Antipsychotic Medications)

Excluded Populations:

  • Patients who expired
  • Patients with an unplanned departure resulting in discharge due to elopement
  • Patients with an unplanned departure resulting in discharge due to failing to return from leave

Data Elements:

Risk Adjustment: No.

Data Collection Approach: Retrospective data sources for required data elements include administrative/billing data and medical records.

Data Accuracy: Hospitals may wish to implement periodic audits to monitor and ensure data accuracy.

Measure Analysis Suggestions: For quality improvement purposes, the measurement system may want to create reports to identify patients discharged on two or more antipsychotic medications without appropriate supporting documentation. This would allow healthcare organizations to target education efforts.

Sampling: Yes. For additional information see the Sampling Section.

Data Reported As: Aggregate rate generated from count data reported as a proportion.
