BACKGROUND:Administration of scheduled antipsychotic therapy to mechanically ventilated patients to prevent or treat delirium is common, despite the lack of evidence to support its use. Among long-term acute care hospital (LTACH) patients requiring prolonged mechanical ventilation (PMV), the frequency of scheduled antipsychotic therapy use, and the factors and outcomes associated with it, have not been described.OBJECTIVE:To identify scheduled antipsychotic therapy prescribing practices, and the factors and outcomes associated with the use of antipsychotics, among LTACH patients requiring PMV.METHODS:Consecutive patients without major psychiatric disorders or dementia who were admitted to an LTACH for PMV over 1 year were categorized as those receiving scheduled antipsychotic therapy (≥24 hours of use) and those not receiving scheduled antipsychotic therapy. Presence of delirium, use of psychiatric evaluation, nonscheduled antipsychotic therapy, and scheduled antipsychotic therapy-related adverse effects were extracted and compared between the 2 groups and when significant (p ≤ 0.05), were entered into a regression analysis using generalized estimating equation techniques.RESULTS:Among 80 patients included, 39% (31) received scheduled antipsychotic therapy and 61% (49) did not. Baseline characteristics, including age, sex, illness severity, and medical history, were similar between the 2 groups. Scheduled antipsychotic therapy was administered on 52% of LTACH days for a median (interquartile range [IQR]) of 25 (6-38) days and, in the antipsychotic group, was initiated at an outside hospital (45%) or on day 2 (1-6; median [IQR]} of the LTACH stay (55%). Quetiapine was the most frequently administered scheduled antipsychotic (77%; median dose 50 [37-72] mg/day). Use of scheduled antipsychotic therapy was associated with a greater incidence of psychiatric evaluation (OR 5.7; p = 0.01), delirium (OR 2.4; p = 0.05), as-needed antipsychotic use (OR 4.1; p = 0.005) and 1:1 sitter use (OR 7.3; p = 0.001), but not benzodiazepine use (p = 0.19).CONCLUSIONS:Among LTACH patients requiring PMV, scheduled antipsychotic therapy is used frequently and is associated with a greater incidence of psychiatric evaluation, delirium, as-needed psychotic use, and sitter use. Although scheduled antipsychotic therapy-related adverse effects are uncommon, these effects are infrequently monitored.
