Self-Assessment Activity: Understanding the Evidence for Off-Label Use of Atypical Antipsychotic Medications
In 2011, the Agency for Healthcare Quality and Research (AHRQ) published a comprehensive report (“Off-Label Use of Atypical Antipsychotics: An Update,” Comparative Effectiveness Review No. 43 [1]) summarizing the evidence for off-label use of antipsychotics for treatment of mental disorders (available at www.effectivehealthcare.ahrq.gov/reports/final.cfm). As described in the report, prescribing of atypical antipsychotics has moved beyond approved indications; however, the effectiveness, benefits, and adverse effects in off-label uses are not well understood. Through a grant from AHRQ, the American Psychiatric Association (APA) developed a FREE multipart CME program to disseminate the conclusions of the AHRQ report and to update clinicians about new developments regarding the evidence.
Our understanding of the evidence continues to evolve. The developers of this program are aware that off-label uses of antipsychotic medications constitute rapidly changing areas in clinical investigation and that new studies and revised Food and Drug Administration (FDA) approvals appear on a regular basis. The material in this program represents the best information available to the developers based on AHRQ reviews and updated literature as of February 2014.
Overall, a class effect of the atypical antipsychotics for each disorder cannot be assumed, and for most atypicals, adequate supporting evidence for either efficacy or comparative effectiveness is still lacking for many indications. The study of the evidence provided in this program will assist the physician in making informed decisions and provide a foundation for discussions with patients about the risks and benefits of this class of medications.
The AHRQ report addressed the following questions.
•.
What are the leading off-label uses of atypical antipsychotics in utilization studies? How have trends in utilization changed in recent years, including inpatient versus outpatient use? What new uses are being studied in trials?
•.
What does the evidence show (and how strong is that evidence) regarding the efficacy and comparative effectiveness of atypical antipsychotics for off-label indications?
•.
How do atypical antipsychotic medications compare with other drugs, including first-generation antipsychotics, for off-label indications?
•.
What are the potential adverse effects and/or complications involved with off-label prescribing of atypical antipsychotics? How do they compare within the class and with other drugs used for the conditions?
The task of the AHRQ reviewers was to review off-label use. It is important to note that other established agents as well as psychosocial treatments are available as first line treatments. Table 1 shows how the strength of evidence assessed in the AHRQ report was classified.
| Strength of Evidence | Criteria |
|---|---|
| High | High confidence that the evidence reflects the true effect. Further research is very unlikely to change the confidence in the estimate of effect. |
| Moderate | Moderate confidence that the evidence reflects the true effect. Further research may change the confidence in the estimate of effect and may change the estimate. |
| Low | Low confidence that the evidence reflects the true effect. Further research is likely to change the confidence in the estimate of effect and is likely to change the estimate. |
| Insufficient | Evidence either is unavailable or does not permit estimation of an effect. |

From “Off-Label Use of Atypical Antipsychotics: An Update,” Comparative Effectiveness Review No. 43. September 2011, Agency for Healthcare Research and Quality, p 12.
Strength of evidence is not the same as the size of the potential effect (i.e., There may be a moderate to high strength of evidence of a beneficial effect, but the size of the effect may be small).
Self-Assessment Activity
Part one of the evidence dissemination program is the self-assessment activity presented as a special feature in this issue of FOCUS. Participants complete a 25-question, multiple-choice self-assessment and assess their strengths and weaknesses regarding their knowledge of evidence for off-label use of atypical antipsychotics. After completing the quiz online at apaeducation.org, participants receive a score report with peer comparison, review the answers and rationales for the quiz, and access links to the AHRQ report and to other important clinical references that describe the evidence for the risks and benefits of these medications.
Look for part 2 of this activity available both at apaeducation.org and also delivered by e-mail as eFocus clinical vignette exercises. After reading a vignette, answer online questions regarding patient management decisions and read the commentary for the best answer choice. You will be able to compare your treatment decisions to those of your peers and receive additional self-assessment CME credit approved by ABPN for MOC part 2. Through completion of this self-assessment and the 10 vignettes that follow, participants will be able to earn up to 25 self-assessment credits for this multipart program.

5. A 28-year-old female veteran is receiving cognitive-processing therapy for intrusive memories of dead bodies she saw while serving in Afghanistan. When she has these memories, she feels as if she is there, and feels extremely distressed. In addition, she finds herself avoiding public places, and startling easily when approached by her family. She describes herself as “angry” all the time; however, she does feel her sleep, appetite, and energy are normal. After several months of therapy she is less irritable but continues to have the intrusive visions. Which of the following medications has the best evidence for efficacy in treating her symptoms?
a.
Quetiapine.
b.
Sertraline.
c.
Prazosin.
d.
Clonazepam.
e.
Risperidone.
6. According to the 2011 AHRQ review, which atypical has the highest level of confidence for effectiveness to support its use in the management of dementia-related agitation?

7. A psychiatry consultation is requested for a 72-year-old nursing home resident with major neurocognitive disorder because of Alzheimer’s disease. In the past, the patient had been violent, injuring both himself and others. Behavioral interventions were tried without success. One year prior, the patient was put on risperidone (1 mg) and showed improvement. An attempt to lower his dose 6 months later resulted in worsening behaviors, and the patient was returned to 1 mg. Since then, there have been no incidents. He also receives hydrochlorothiazide and atenolol for hypertension. His gait is somewhat slow but the nurses insist that this was the case before he was started on risperidone.
A recent pharmacy review questioned the use of antipsychotics for a nonpsychotic patient and informed the Director of Nursing that these drugs are associated with increased mortality in patients with dementia. As a result, the Director of Nursing is requesting an alternative drug. The patient’s family, however, expresses concern over the possibility that the patient’s agitation may return. Which of the following would be the most appropriate recommendation for a psychiatric consultant to give?
a.
Continue the risperidone, titrating to lowest effective dose.
b.
Continue the risperidone but add adjunctive benztropine.
c.
Discontinue risperidone and use behavioral interventions instead.
d.
Discontinue risperidone and administer fluoxetine.

Switch from risperidone to aripiprazole.

a.
Aripiprazole.
b.
Olanzapine.
c.
Quetiapine.
d.
Risperidone.
e.
Ziprasidone.
9. In nonelderly adults (18–64) taking atypical antipsychotic medications, what does the evidence show about antipsychotics and weight gain in this patient group?

d.
Quetiapine is associated with the most weight gain.
e.
