Purpose: Secondary to the risk of antipsychotic-induced acute dystonia, prophylactic use of benztropine is occasionally warranted but is recommended for no longer than 7 days after initiating an antipsychotic, correlating to the period of highest dystonia risk. Despite the associated increased anticholinergic burden, many clinicians continue to order benztropine for periods exceeding the recommended prophylactic duration. We investigated the reduction of benztropine use duration subsequent to implementation of truncated electronic entry orders to improve benztropine prescribing within an acute psychiatric facility.
Methods: Data were collected for psychiatric inpatients admitted between January and June 2020 who were prescribed scheduled benztropine. In a quality improvement initiative implemented in April 2022, electronic orders for benztropine were modified from a 180-day to a 7-day duration, with subsequent postintervention data collection. The primary outcomes included a change in the duration of benztropine use for any indication in the hospital, and a change in the percentage of patients meeting predetermined "unnecessary use" criteria. Secondary analyses included the percentage of patients with discharge prescriptions for scheduled benztropine (either for prophylaxis or for other indications) in the pre- and postintervention periods.
Results: 73 pre- and 77 postintervention individual patients/encounters were included. Following the intervention, in-hospital duration of benztropine use for any indication decreased from a median of 14 days to a median of 7.5 days (P < 0.05), and appropriate use increased by 92.9%. The percentage of patients with prescriptions for scheduled benztropine decreased from 67.1% in the preintervention group to 29.9% in the postintervention group.
Conclusion: Decreased benztropine use duration, by means of truncated order entry sentences, during inpatient psychiatric admissions, appears feasible regardless of dual antipsychotic or first-generation antipsychotic use, and may reduce the rates of benztropine prescriptions written for discharge.

Background: Cognitive dysfunction is a non-motor manifestation of Parkinson's disease (PD). We aimed to determine the frequency and patterns of cognitive dysfunction in treated patients with PD and their predictors.
Research Design And Methods: This study included 80 patients (male = 48; female = 32) and 30 healthy individuals.
Background: Cholinergic discontinuation symptoms, also known as "cholinergic rebound," from abrupt clozapine discontinuation are characterized by a range of somatic and psychiatric symptoms.
Objective: The objective of this study was to describe the clinical features and management options for clozapine withdrawal-associated cholinergic rebound syndrome (henceforth referred to as CWCRS) and present an illustrative case report.
Methods: Based on a literature search of the databases PubMed, OVID Medline, and Embase as well as reviewing reference lists of relevant past reviews, we carried out a systematic review of case reports on the management of CWCRS from 1946 to 2023.
