TREATMENT A first-generation antipsychotic
When Ms. L is admitted to the psychiatric unit, she is started on oral perphenazine, 8 mg twice daily, and venlafaxine, 75 mg/d, which she was taking prior to hospital admission. Because she had tolerated venlafaxine with no adverse effects, it seems worthwhile to optimize the dose of this medication rather than start a new medication.
During the week, Ms. L’s perphenazine is titrated up to 24 mg twice daily and venlafaxine is titrated to 150 mg/d. A Montreal Cognitive Assessment (MoCA) is performed within the first 2 days of admission and she scores 16/30, indicating moderate cognitive impairment. On Friday, the attending physician explains that her medications should start to have therapeutic effect. During this time, this clinician engages in cognitive restructuring by providing validation of Ms. L’s suffering, verbal support, and medication compliance counseling. At this time, the treating team also suggests to Ms. L that she should expect the activity and effects of the bugs to dissipate. She is receptive to this suggestion. She also participates in the milieu, including unit activities, but is limited in her ability to engage in group therapy due to the intensity of her illness.
Throughout the weekend, the on-call physician also engages Ms. L and reports minor improvement.
OUTCOME Significant relief
On re-evaluation Monday morning—almost a week after Ms. L had been admitted to the inpatient psychiatric unit—she has achieved significant relief from her delusions. She says that she has no idea where the bugs have gone. Ms. L appears to be a completely different person. She no longer appears guarded. The suspiciousness, paranoia, hopelessness, and negative outlook she previously experienced have significantly diminished. Her MoCA score improves to 25/30, indicating no cognitive impairment (Table). She is discharged after a 7-night stay on the inpatient psychiatric unit.
