Pharmacist-Driven Alcohol Use Disorder Screening May Increase Inpatient Utilization of Extended-Release Naltrexone: A Single Center Pilot Study.

Individuals with mental illness have a high incidence of comorbid substance use, with one of the most prevalent being alcohol use disorder (AUD). Naltrexone, FDA-approved for AUD, decreases reward associated with alcohol-related social cues. This study aimed to determine if a pharmacist-driven screening tool would increase the use of extended-release naltrexone (XR-NTX) in patients with AUD and a comorbid psychiatric condition. Pharmacists screened and recommended XR-NTX for adults admitted to the inpatient psychiatric unit, who had a DSM-5 diagnosis of AUD, a negative urine drug screen for opioids, and were hospitalized for at least 1 day. Endpoints evaluated included the number of XR-NTX doses administered during the screening period to the prescreening period, 30-day readmission rates, recommendation acceptance rates, and reasons for not administering XR-NTX. Pharmacists identified 66 of 641 screened patients who met the inclusion criteria and were candidates for XR-NTX. Compared to the preintervention period, more patients received XR-NTX for AUD (2 vs. 8). Readmission rates were similar between those with AUD who received XR-NTX and those who did not. Pharmacist-driven screening for AUD led to greater administration of XR-NTX when compared to the same 4-month period the year prior to initiating the study.

Impact of traditional versus nontraditional initiation dosing schedule of paliperidone palmitate on 30-day readmission and safety.

Introduction: Paliperidone palmitate (PP), a second-generation long-acting injectable antipsychotic, requires 2 injections upon initiation. Due to the fast-paced nature of the inpatient setting, the second dose may be administered earlier than recommended by labeled use despite the lack of evidence that evaluates this practice. Methods: This was a retrospective chart review that investigated the outcomes associated with the timing of the second PP initiation dose with the aim of comparing patients who received the second PP dose fewer than 3 days after the first injection with those who received it between 3 and 11 days after the first injection. The primary outcomes included 30-day psychiatric readmission, index hospitalization length of stay, and time until the next psychiatric hospitalization. Secondary outcomes included 6-month readmission and the percentage of patients who experienced an adverse event after the second injection. Results: No statistically significant differences were observed between groups for 30-day readmission. There was a statistically significant shortened index length of hospitalization (median, 2 vs 4 days; P < 0.001) and a non-statistically significant trend for time until the next psychiatric hospitalization (median, 25 vs 47 days) when comparing those who received the nontraditional loading regimen to those who received the traditional labeled loading regimen. No differences were observed in the secondary outcomes or safety/tolerability. Discussion: The results of the study indicate that there are no significant differences in readmission rates and adverse drug reactions in those who received the second PP dose earlier than recommended per labeled use. Larger, controlled studies are needed to further investigate clinical and safety outcomes.

Impact of Board Certified Psychiatric Pharmacists on improving urinary tract infection antibiotic appropriateness at an acute psychiatric hospital.

Introduction: Urinary tract infections (UTIs) are one of the most common indications for antibiotic use; patients with psychiatric disorders have a greater risk for UTI compared with patients without these disorders. However, there is little guidance on how best to manage antibiotic therapy in psychiatric hospitals. This study assessed the impact of a Board Certified Psychiatric Pharmacist (BCPP)-driven guideline on managing UTI treatment in an acute psychiatric hospital. Methods: The guideline was developed by the psychiatric pharmacy team and distributed to internists, psychiatrists, and pharmacists. Preintervention data were assessed for patients admitted between November 30, 2019, and February 23, 2020; postintervention data were assessed from February 25, 2020, to April 24, 2020. All patients ages 13 years and older who were admitted and had orders for an antibiotic to treat a UTI were included in this study. Appropriate UTI management was defined as an appropriate agent, dose, route, and frequency per the treatment guideline. Additionally, the following criteria were to be ordered and assessed to be deemed appropriate: urinalysis, urine culture, complete blood count, basic or complete metabolic panel, temperature, and subjective symptoms. Results: Before intervention, 19.0% of antibiotic orders were appropriate; after intervention, 46.7% of antibiotic orders were appropriate (P = .048). Conclusion: The implementation of a BCPP-driven treatment algorithm was associated with a significant increase in appropriate antibiotic regimens for the treatment of UTIs in patients admitted to a psychiatric hospital.

Prescribing Practices for Agitation Medication in Obese Patients Admitted to the Emergency Department.

INTRODUCTION: Weight is a factor that influences the dosages of many medications, although no clinical studies have evaluated this factor in the use of agitation medications in the obese population. The objectives of this study were to assess the need for weight considerations in dosing antipsychotics and benzodiazepines for patients with agitation and to assess prescribing patterns in agitated patients. METHODS: This retrospective cohort study compared outcomes between obese and nonobese adult patients who received at least one parenteral administration of an antipsychotic or benzodiazepine for agitation in the emergency department. The primary outcomes were total antipsychotic and benzodiazepine doses within 24 hours (in chlorpromazine equivalents and lorazepam equivalents, respectively). Key secondary outcomes included antipsychotic and benzodiazepine doses used for first administration, incidence of repeat emergency medication administration within 24 hours, time to next administration, and number of repeat administrations within 24 hours. RESULTS: The study examined 115 patient encounters in each cohort of patients in the study. The baseline characteristics of the 2 study cohorts were similar. Both groups had similar mean 24-hour antipsychotic usage [272.7 chlorpromazine equivalents (nonobese cohort), 313.5 chlorpromazine equivalents (obese cohort); P=0.157] and mean 24-hour benzodiazepine usage [0.9 lorazepam equivalents (both cohorts); P=0.750]. Differences between the study cohorts on all of the secondary outcomes were also not statistically significant (P>0.05). DISCUSSION: This study did not find the use of higher dosages of agitation medication in the obese compared with the nonobese population. Future prospective trials, with possible emphasis on individual medications, specific etiologies of agitation, or morbid obesity, are required to confirm this finding or to elucidate potential differences in optimal medication dosages for the obese population.

Impact of a pharmacist-driven tardive dyskinesia screening service.

INTRODUCTION: Tardive dyskinesia (TD) is defined as involuntary movements that can develop with prolonged antipsychotic use. Regular monitoring using the Abnormal Involuntary Movement Scale (AIMS) is recommended to be conducted every 3 to 6 months for early recognition, although the AIMS is underused. Several studies have investigated risk factors that may be associated with TD, including age, sex, and long-term antipsychotic use. This study aimed to increase the monitoring and treatment of TD for those assessed to be at higher risk. METHODS: This was a prospective quality improvement study on the effectiveness of a psychiatric pharmacist-driven TD screening service (PPDTSS) in an inpatient psychiatric facility. Participants were composed of adult patients admitted between May and November 2018. Patients were screened daily by a clinical pharmacist and, if determined to be high risk based on studied risk factors, prioritized to receive a formal TD screening via the AIMS. The primary objective was to optimize standard of care by increasing the number of AIMS screenings conducted. The secondary objective was to increase the treatment of TD. RESULTS: A total of 402 patients were assessed prior to implementation of the PPDTSS, and 390 patients were screened following implementation. The PPDTSS increased the number of AIMS screenings attempted by 85.1% for high-risk individuals. Of the 75 patients who had an AIMS screening attempted in the postintervention group, 46 (61.3%) had an AIMS screening completed, of which 3 (6.5%) were positive. DISCUSSION: The results of this study demonstrate that psychiatric pharmacists can be used to improve the regular monitoring of patients at high risk for TD.
