Complexity of patients with mental healthcare needs cared for by mental health clinical pharmacist practitioners in Veterans Affairs.

PURPOSE: The complexity of patients with mental healthcare needs cared for by clinical pharmacists is not well delineated. We evaluated the complexity of patients with schizophrenia, bipolar disorder, and major depressive disorder (MDD) in Veterans Affairs (VA) cared for by mental health clinical pharmacist practitioners (MH CPPs). METHODS: Patients at 42 VA sites with schizophrenia, bipolar disorder, or MDD in 2016 through 2019 were classified by MH CPP visits into those with 2 or more visits ("ongoing MH CPP care"), those with 1 visit ("consultative MH CPP care"), and those with no visits ("no MH CPP care"). Patient complexity for each condition was defined by medication regimen and service utilization. RESULTS: For schizophrenia, more patients in ongoing MH CPP care were complex than those with no MH CPP care, based on all measures examined: the number of primary medications (15.3% vs 8.1%), inpatient (13.7% vs 9.1%) and outpatient (42.6% vs 29.7%) utilization, and receipt of long-acting injectable antipsychotics (36.7% vs 25.8%) and clozapine (20.5% vs 9.5%). For bipolar disorder, more patients receiving ongoing or consultative MH CPP care were complex than those with no MH CPP care based on the number of primary medications (27.9% vs 30.5% vs 17.7%) and overlapping mood stabilizers (10.1% vs 11.6% vs 6.2%). For MDD, more patients receiving ongoing or consultative MH CPP care were complex based on the number of primary medications (36.8% vs 35.5% vs 29.2%) and augmentation of antidepressants (56.1% vs 54.4% vs 47.0%) than patients without MH CPP care. All comparisons were significant (P < 0.01). CONCLUSION: MH CPPs provide care for complex patients with schizophrenia, bipolar disorder, and MDD in VA.

Assessment of hepatitis C monitoring adherence after viral eradication in veterans with substance use to improve care and surveil reinfection.

Introduction: Hepatitis C virus (HCV) incidence rates are rising for patients with substance use and/or SUDs. Guidelines provide monitoring recommendations to ensure remission after successful treatment. The study's objective was to identify gaps in follow-up for patients with documented substance use and/or SUD through assessment of adherence to guideline-recommended HCV RNA lab 12 months post-treatment. Methods: Patients treated for HCV through the Veteran Health Indiana Hepatitis C Pharmacy Clinic were retrospectively evaluated. Subjects were categorized based on the provider assigned for follow-up care after 12-week sustained virologic response (SVR12) labs (primary care provider [PCP] or HCV provider). The primary outcome was HCV RNA obtained 11 to 13 months post-treatment. Secondary outcomes were HCV RNA detected post-treatment, substance use, engagement in substance use treatment, and engagement with social work. Results: Two hundred forty-one patients were included in the HCV provider cohort and 139 in the PCP cohort. Forty-one patients did not have a specified clinic for follow-up treatment, and 20 patients did not achieve SVR12. Sixty-one patients (28%) in the HCV provider cohort completed a 12-month HCV RNA within 11 to 13 months post-treatment vs 15 patients (11%) in the PCP cohort (P ≤ .01). One patient had HCV RNA detected post-treatment. Discussion: This study reveals inadequate HCV post-treatment follow-up for patients with substance use and/or SUD. SUD is a chronic disease that requires continued monitoring to prevent complications. Further studies are needed to identify reinfection rates and improvements of care in this population.

Best practice model for outpatient psychiatric pharmacy practice, part 1: Development of initial attribute statements.

Introduction: A 2019 survey identified significant variability of practice characteristics among outpatient psychiatric pharmacists (OPPs). No published model establishes which attributes constitute best practice for OPPs. By developing a consensus for best practice model attributes, OPPs can work toward consistent, effective patient care. This project aimed to develop attribute statements for a best practice model for OPPs providing direct patient care. Methods: Board Certified Psychiatric Pharmacists and American Association of Psychiatric Pharmacists (AAPP) members were questioned using a 5-phase (P1-P5) survey and summit approach. The phases were: P1, broad ideation survey; P2, 10-person summit to develop draft statements; P3, survey of the draft statements for acceptance; P4, summit to resolve review feedback; and P5, survey of AAPP membership to confirm the finalized statements. Results: P1 survey results generated a list of 143 possible attributes that informed the P2 summit, which were refined to 28 statements. P3 survey results confirmed at least 70% agreement with each statement. The P4 summit evaluated all P3 survey results and made significant modifications to 4 statements. Informal feedback was sought with other stakeholders, and supporting narratives and references were developed to provide clarity regarding the intent of each statement. Finalized statements and supporting narratives were confirmed in the P5 survey. Discussion: The 28 attribute statements were developed over 18 months by gathering input and consensus through multiple modalities, including 3 surveys, 2 summit meetings, and numerous informal feedback requests. The agreement on the attribute statements was consistently high across all phases. The final attribute statements are presented elsewhere in this issue.

Best practice model for outpatient psychiatric pharmacy practice, part 2: Confirmation of the attribute statements.

Introduction: The American Association of Psychiatric Pharmacists (AAPP) used multiple modalities to develop and refine 28 attribute statements to describe a best practice model for outpatient psychiatric pharmacists. Before addressing implementation, assessment, and field testing, it was necessary to finalize and confirm the statements and their supporting narratives among stakeholders. The objective of this project was to confirm the attribute statements and supporting justifications for a best practice model for outpatient psychiatric pharmacists providing direct patient care. Methods: The 4 phases that resulted in the 28 attribute statements and supporting narratives have been described and published elsewhere. As part of phase 5, the confirmation survey was distributed to pharmacists and resident members of AAPP in November 2021 for 3 weeks. Results: The survey respondents (n = 74; 6.1%) were licensed pharmacists for an average of 15.6 years (SD = 12.0) and had been practicing as psychiatric pharmacists for an average of 11.3 years (SD = 10.4). Slightly more than half (54.2%) of the respondents reported practicing in the outpatient setting and three-fourths (74.3%) were Board Certified Psychiatric Pharmacists. For each of the 28 statements, more than 90% of respondents either agreed or agreed with minimal reservations. Discussion: Given the high degree of agreement on the proposed practice model statements, they will be used as the basis for the outpatient psychiatric pharmacist best practice model. Next steps in developing this model include establishing implementation guidance, determining appropriate metrics for evaluation of these statements in practice, and establishing appropriate field-testing methods.

Management of treatment-resistant generalized anxiety disorder.

Generalized anxiety disorder (GAD) is characterized by persistent and excessive worry. Around half of the patients treated for GAD will fail to respond to initial treatment. Treatment-resistant (or refractory) GAD is defined as failure to respond to at least 1 trial of antidepressant therapy at adequate dose and duration. Review of the literature indicates several potential medication classes and individual agents that can be used as augmentation strategies to treat residual symptoms when recommended therapy per clinical practice guidelines fails. A thorough literature search revealed 2 medication classes with the largest amount of data to support their use in treatment-resistant GAD treatment: gamma-aminobutyric acid-related agents and atypical antipsychotics. This article focuses on evidence-based recommendations for the use of these agents as adjunctive therapies for patients with treatment-resistant GAD. Different pharmacologic approaches to use these agents are demonstrated through 2 patient cases in which patients have failed first-line treatment options.

Relapse rates among veterans on maintenance doses of combination buprenorphine and naloxone for opioid use disorder.

INTRODUCTION: Opioid use disorder (OUD) can cause significant morbidity and mortality with more than 115 people dying from an opioid overdose daily in the United States. Treatment with buprenorphine/naloxone (BUP/NAL) can be effective; however, there is conflicting evidence on the utility of higher doses in preventing relapse. This study was designed to assess BUP/NAL maintenance doses and the rate of relapse in veterans with OUD. METHODS: Patients diagnosed with OUD who received a prescription for BUP/NAL through the substance use disorder recovery program were retrospectively evaluated. Patients were categorized into 2 treatment groups: those prescribed ≤16 mg of BUP/NAL daily and those prescribed >16 mg of BUP/NAL daily. The primary outcome was to determine rates of relapse between maintenance doses of BUP/NAL. Secondary outcomes included evaluating the difference in rates of relapse between daily versus take-home dosing, tablets versus films, time to relapse, and use of illicit substances during treatment. RESULTS: Patients prescribed >16 mg of BUP/NAL daily had statistically significantly lower rates of relapse compared to patients prescribed ≤16 mg of BUP/NAL daily (P = .0018). Regarding secondary outcomes, there was a statistically significant difference in time to relapse (P = .036) and dosage form (P = .0124). Difference in administration of dose and illicit substance use during treatment were not statistically significant. DISCUSSION: This study identified that rate of relapse can be lowered and time to relapse can be lengthened when doses >16 mg of BUP/NAL are prescribed in the veteran population for OUD.

Treatment outcomes of long-acting injectable naltrexone versus oral naltrexone in alcohol use disorder in veterans.

INTRODUCTION: In veterans, the prevalence of 12-month and lifetime alcohol use disorder (AUD) is 14.8% and 42.2%, respectively. Alcohol use disorder treatment is often plagued by medication discontinuation with relapse rates being as high as 39% in patients who sought treatment. One proposed benefit of long-acting injectable (LAI) medications is improved adherence. The purpose of this trial was to compare the difference in time to relapse between patients on oral and LAI naltrexone. METHODS: This study was a retrospective electronic chart review of patients with AUD who were treated with oral or LAI naltrexone at a Veteran's Affairs Medical Center from August 1, 2016, to July 31, 2018. The primary outcome assessed was time to relapse. Secondary outcomes for this study included medication possession ratio (MPR), comorbid mental health diagnosis, substance use, past pharmacological treatment, liver and kidney function, and enrollment in addiction-focused psychosocial therapy. RESULTS: Thirty-two patients met inclusion criteria. The median time to relapse was longer for those treated with LAI naltrexone versus oral naltrexone (150.5 days vs 50.5 days, P < .01). The MPR was similar among both groups (P = .47). No significant differences were found between the groups regarding safety outcomes. DISCUSSION: Results suggest that LAI naltrexone is associated with increased time to relapse and should be considered as a first-line option for patients. Given the retrospective nature and small sample size of this study, larger, randomized, controlled trials comparing LAI and oral naltrexone head to head would help determine most appropriate treatment for these patients.

Evaluation of adherence and persistence with oral versus long-acting injectable antipsychotics in patients with early psychosis.

INTRODUCTION: Despite the theory that long-acting injectable (LAI) antipsychotics should be more likely to improve adherence, reduce gaps in therapy, and prevent relapse compared with oral antipsychotics, there is little published evidence on this issue, specifically in patients with early psychosis. METHODS: Patients with a new diagnosis for a psychotic disorder between July 1, 2013, and August 31, 2014, were retrospectively evaluated during a 12-month duration. The primary outcomes were adherence and persistence. Adherence was determined by proportion of days with medication, and persistence was defined as zero gaps in medication therapy. The secondary outcome was the number of times a psychiatric acute care service was used. Patients were divided into 3 groups based on their antipsychotic prescription history: oral only, LAI only, or both formulations at separate times throughout the study period. RESULTS: Forty-seven patients met inclusion criteria. The average proportions of days with medication were 32%, 76%, and 75% for the oral, LAI, and both formulations groups, respectively (P < .001). For medication persistence, there were 32 patients (91%), 3 patients (75%), and 5 patients (63%) with at least 1 gap in therapy for the oral, LAI, and both formulations groups, respectively (P = .098). For acute care services, there was a median number of zero acute care visits for each of the 3 groups (P = .179). A post hoc subgroup analysis found medication adherence to be statistically different between the oral and LAI groups. DISCUSSION: Long-acting injectable antipsychotics were associated with better adherence compared with oral antipsychotics in patients with early psychosis.

Development of a precepting workshop for pharmacy residents.

PURPOSE: The process of developing a workshop to enhance pharmacy residents' precepting skills and confidence in serving as preceptors is described, and survey results indicating the program's effectiveness are presented. SUMMARY: In response to requests from pharmacy residents for structured precepting-specific training to augment their participation in teaching certificate programs, Indianapolis, Indiana-based Eskenazi Health launched a series of annual workshops designed to hone residents' precepting skills. First offered as a half-day program in January 2011, the workshop was expanded in 2014 to a full-day format, with pharmacists from several local residency programs invited to attend. The workshop includes didactic sessions covering a wide range of topics (e.g., the four preceptor roles, techniques for providing effective feedback, strategies for dealing with difficult situations), as well as a panel discussion during which new and experienced preceptors share insights on effective teaching and precepting challenges; continuing-education credit is available. A total of 51 postgraduate year 1 or 2 residents from nine local rotation sites attended the 2014 workshop. The results of surveys administered before and after the workshop indicated that workshop attendance was associated with significant improvement in residents' comfort level in the 24 skill areas covered in the workshop and their ability to serve as copreceptors. CONCLUSION: A workshop was developed to assist pharmacy residents in developing precepting skills. Positive feedback about the program was received from attendees.
