Impact of pharmacists on outcomes for patients with psychiatric or neurologic disorders

Board-Certified Psychiatric Pharmacists and Their Potential Role in Addressing Behavioral Health Workforce Shortages

Board-certified psychiatric pharmacists (BCPPs) are doctorate-level, board-certified experts in managing medications for people living with psychiatric disorders, including substance use disorders. BCPPs work as part of an integrated health care team that provides comprehensive medication management focused on optimizing medication-related outcomes and ensuring the safety of the prescribed medications. The authors describe BCPP education and training, settings in which BCPPs practice, and in what roles. Current policies that limit BCPP involvement in behavioral health care and proposed solutions to support the role of BCPPs in addressing behavioral health workforce shortages are discussed.

Systematic literature review of the impact of psychiatric pharmacists

Introduction

Pharmacists focusing on psychotropic medication management and practicing across a wide variety of healthcare settings have significantly improved patient-level outcomes. The Systematic Literature Review Committee of the American Association of Psychiatric Pharmacists was tasked with compiling a comprehensive database of primary literature highlighting the impact of psychiatric pharmacists on patient-level outcomes.

Methods

A systematic search of literature published from January 1, 1961, to December 31, 2022, was conducted using PubMed and search terms based on a prior American Association of Psychiatric Pharmacists literature review. Publications describing patient-level outcome results associated with pharmacist provision of care in psychiatric/neurologic settings and/or in relation to psychotropic medications were included. The search excluded articles for which there was no pharmacist intervention, no psychiatric disorder treatment, no clinical outcomes, no original research, no access to full text, and/or no English-language version.

Results

A total of 4270 articles were reviewed via PubMed, with 4072 articles excluded based on title, abstract, and/or full text in the initial pass and 208 articles selected for inclusion. A secondary full-text review excluded 11 additional articles, and 5 excluded articles were ultimately included based on a secondary review, for a final total of 202 articles meeting the inclusion criteria. A comprehensive database of these articles was compiled, including details on their study designs and outcomes.

Discussion

The articles included in the final database had a wide range of heterogeneity. While the overall impact of psychiatric pharmacists was positive, the study variability highlights the need for future publications to have more consistent, standardized outcomes with stronger study designs.

Clinical pharmacist interventions in the transition of care in a mental health hospital: case reports focused on the medication reconciliation process

The transition of care represents a key point in the hospital admission and discharge process. A comprehensive transition could lead to fewer medication-related problems. The hospital clinical pharmacist could help in the transition of care process with a comprehensive medication reconciliation process, which has been poorly described in mental health hospitals. This study presents two clinical cases in which hospital clinical pharmacists identified omitted medications and other medication-related issues, including medication errors, during the transition of care in a mental health hospital. These positive experiences may encourage other countries to establish similar collaborations with hospital clinical pharmacists in mental health hospitals.

Prevalence and predictors of inappropriate prescribing in outpatients with severe mental illness

Background

Potentially inappropriate prescribing (PIP) is frequent in geriatrics and results in an increased risk for adverse effects, morbidity, mortality and reduced quality of life. Research on PIP in psychiatry has mainly focused on elderly patients and inpatients.

Objectives

To determine the prevalence and the predictors of PIP of psychotropic medication in outpatients with severe mental illness.

Design

This study is part of the Muva study, a pragmatic open Stepped Wedge Cluster Randomized Trial of a physical activity intervention for patients (age ⩾ 16 years) with severe mental illness.

Methods

A structured medication interview, questionnaires on social functioning, quality of life and psychiatric symptoms, and BMI and waist circumference measurements were performed followed by a structured medication review. Patients were divided into groups: PIP versus no PIP. Between-group differences were calculated and a multivariate binary logistic regression was performed to examine predictors for PIP. A receiver operating characteristics analysis was performed to determine the area under the curve (AUC).

Results

In 75 patients, an average of 5.2 medications of which 2.5 psychotropic medication was used. 35 (46.7%) patients were identified with PIP. Unindicated long-term benzodiazepine use was the most frequently occurring PIP (34.1%). Predictors of PIP were female gender [odds ratio (OR) = 4.88, confidence interval (CI) = 1.16-20.58, p = 0.03], number of medications (OR = 1.41, CI = 1.07-1.86, p = 0.02) and lower social functioning (OR = 1.42, CI = 1.01-2.00, p = 0.05). The AUC was 0.88 for the combined prediction model.

Conclusion

The prevalence of PIP of psychotropic medication in outpatients with severe mental illness is high. It is therefore important to identify, and where possible, resolve PIP by frequently performing a medication review with specific attention to females, patients with a higher number of medications and patients with lower social functioning.

Trial registration

This trial was registered in The Netherlands Trial Register (NTR) as NTR NL9163 on 20 December 2020 (https://trialsearch.who.int/Trial2.aspx?TrialID=NL9163).

Clinical pharmacy services in mental health in Europe: a commentary paper of the European Society of Clinical Pharmacy Special Interest Group on Mental Health

A large proportion of the world's disease burden is attributable to mental illnesses. Although effective interventions are available, many patients still have limited access to evidence-based treatments. Aside from access, treatment gaps, including inappropriate medication selection and monitoring, are also routinely recognised. Mental health clinical pharmacists can help address these gaps and enable patients to receive optimised pharmaceutical care, particularly appropriate medication selection and monitoring. The European Society of Clinical Pharmacy (ESCP) Special Interest Group on Mental Health was established to improve standardised service provision in mental health settings across Europe. The Special Interest Group identified significant barriers (predominantly associated with reimbursement and position within the multidisciplinary team) to effective pharmaceutical care amongst those with mental illnesses. This commentary presents recommendations to address these gaps through improved mental health clinical pharmacy service provision.

Evaluation of a training program to support the implementation of a community pharmacist-led support service for people living with severe and persistent mental illness

BACKGROUND

With appropriate training, community pharmacists can support people living with severe and persistent mental illness (SPMI) by identifying and managing medication-related issues and physical health concerns. The Bridging the Gap between Physical and Mental Illness in Community Pharmacy (PharMIbridge) randomized controlled trial (RCT) tested the impact of an individualized, pharmacist-led support service for people living with SPMI.

OBJECTIVE(S)

To evaluate the impact of the PharMIbridge training program on pharmacy participants' knowledge and confidence, as well as stigma and attitudes, in relation to supporting, and providing services to, people living with SPMI; compared to Mental Health First Aid (MHFA) training alone.

METHODS

Pharmacy staff (n = 140) from 55 community pharmacies across four RCT regions attended face-to-face training. Both intervention group (IG) and comparator group (CG) participants received MHFA training while IG participants received additional PharMIbridge training, involving role-plays and mental health consumer educators (MHCEs). A questionnaire including validated instruments was administered at baseline, after training and after 12 months. Comparative analyses included paired t tests and mixed between/within analysis of variance (ANOVA).

RESULTS

Pre and post-training surveys were completed by 136 participants, most of which were pharmacists. Both IG and CG participants had significant reductions in stigma (P < 0.001) post-training. IG participants' confidence and knowledge regarding metabolic monitoring significantly improved compared to CG (P < 0.001). IG participants were significantly more confident and comfortable in providing medication counseling, compared to CG participants (P < 0.05).

CONCLUSION

MHFA training reduced participants' stigma toward mental health. However, the purpose-designed PharMIbridge training program provided pharmacists with additional knowledge and skills to confidently support the physical health care needs of people living with SPMI. The inclusion of role-plays and MHCEs allowed pharmacists to self-reflect and practice skills in safe, supportive environments. Future studies should continue to involve MHCEs in pharmacy training and explore whether these improvements are sustainable.

Antipsychotic treatment in elderly patients on polypharmacy with schizophrenia

PURPOSE OF REVIEW

Elderly patients with schizophrenia (SCH) are treated with antipsychotics and are often on different comedications, including polypharmacy (five or more medications). Evidence-based guidelines and randomized controlled trials do not include patients on polypharmacy, something that represents a 'gap' between evidence-based recommendations and clinical prescribing patterns. In this context, narrative reviews are needed to help clinicians in daily practice.

RECENT FINDINGS

Antipsychotic treatment efficacies in meta-analyses are similar in the elderly with SCH compared with the general population (medium effect size). Long-term cohort studies show that antipsychotic treatment reduces overall mortality, hospitalizations, and cardiovascular death. These studies are limited because polypharmacy was not studied. The prevalence of antipsychotic use as potentially inappropriate medications was very high in nursing homes (25%). The prevalence of antipsychotic polypharmacy was 40%. Different strategies to manage these problems are available, including collaboration with clinical pharmacists, leading to reduced polypharmacy and better adherence to treatment guidelines.

SUMMARY

Elderly patients with SCH on polypharmacy are less frequently studied, although they represent many patients with SCH. Different potentially inappropriate medication lists and collaboration with clinical pharmacists represent effective strategies for medication optimization. More studies are needed on this topic (e.g., prospective nonrandomized studies).

Systematic review of community pharmacist administration of long-acting injectable antipsychotic medications

BACKGROUND

Long-acting injectable antipsychotic (LAIA) medications offer an effective treatment option for patients with serious mental illness. Despite demonstrated clinical safety and efficacy as well as increased adherence and less frequent administration compared with daily oral regimens, LAIAs remain underutilized in clinical practice. With legislation allowing pharmacists to administer injectable medications in 48 U.S. states, community pharmacies are uniquely positioned to serve as an access point for patients with serious mental illnesses to receive LAIA injections.

OBJECTIVE

This study aimed to conduct a systematic review of the health and economic benefits and costs of community pharmacist administration of LAIA medications.

METHODS

A systematic search of the literature published from January 1996 to April 2022 was conducted across 3 databases (Embase, PubMed, and Scopus Plus). Publications describing pharmacist administration of LAIA medications in outpatient settings were included. Publications that examined the use of LAIAs but did not involve a pharmacist administering the medication were excluded.

RESULTS

Of 2261 publications reviewed, we identified 8 publications (4 articles and 4 abstracts) that met our inclusion criteria, of which only 7 included results. Four studies reported high medication adherence achieved by patients receiving pharmacist-administered LAIAs. Two publications surveyed patient satisfaction with pharmacist administration of LAIAs in community pharmacy settings. One study found pharmacists' mixed attitudes regarding LAIA administration and time and safety barriers to offering the service.

CONCLUSION

We found very little evidence on the impact of pharmacist administration of LAIAs on patient outcomes. This review highlights the need to generate greater evidence on the health and economic benefits as well as financial models for pharmacists to administer LAIA medications in outpatient and community pharmacy settings. Such evidence could support more community pharmacists to offer LAIA medications and contribute to the shift toward value-based care.

Pharmacists in clozapine clinics improving physical health monitoring

Introduction

People living with schizophrenia have a higher rate of comorbid physical health diseases and compared with the general population die earlier due to these diseases. A pharmacist working in an outpatient mental health clinic setting could assist with the management of physical health disease for this population. The aim of this study was to investigate whether having a pharmacist in a community clozapine clinic would improve adherence to physical health monitoring and whether this would have a positive effect on these physical health outcomes.

Methods

This retrospective observational study compared patient data from 2 clozapine clinics; one where a pharmacist engaged in medication reviews and management of medication side effects, and another that did not have a pharmacist. The rates of physical health monitoring and the changes from baseline of physical health outcomes (weight, BMI, BP, HbA1c, and lipids) were compared after the first pharmacist intervention (medication review).

Results

The pharmacist clinic had statistically higher rates of metabolic and ECG monitoring (glucose 48% vs 11%, P &lt; .001; lipids 61% vs 7.1%, P &lt; .001; ECG 15% vs 0%, P = .001). Positive trends in weight were identified in the pharmacist-group, although this failed to reach statistical significance.

Discussion

This study shows that pharmacists providing regular medication reviews improves physical health monitoring for patients receiving clozapine.

Positioning psychiatric pharmacists to improve mental health care

Psychiatric pharmacy continues to grow and look to the future with a focus on helping individuals recover from mental health and substance use disorders. The American Association of Psychiatric Pharmacists (AAPP) considers Board Certified Psychiatric Pharmacist (BCPP) the gold standard credential that all psychiatric pharmacists should attain to demonstrate specialized knowledge and expertise in psychiatry. BCPPs are part of collaborative interprofessional teams and practice in hospitals, clinics, and diverse health systems. Two out of 3 BCPPs practicing in clinics have prescriptive authority. BCPPs improve access, safety, medication adherence, and therapeutic outcomes. Every person with a mental health and substance use disorder should have access to a BCPP providing comprehensive medication management (CMM) and psychotropic stewardship aimed at improving population health. BCPPs are in demand owing to their expertise. AAPP envisions growth and expansion of the BCPP role in many areas including coordinating psychiatric transitions of care and telehealth services, managing long-acting injectable medication clinics, providing pharmacogenomic consultation, conducting clozapine and lithium monitoring, managing medications for substance use disorders, leading medication groups, CNS drug development, research, and provider education. To prepare the workforce, colleges and schools of pharmacy should hire BCPPs for optimal curriculum development, and each student pharmacist should have an opportunity to develop a therapeutic alliance with a person recovering from psychiatric illness. Postgraduate year (PGY) 1 residencies should offer learning experiences in psychiatric pharmacy to prepare residents to enter an expanded number of PGY2 psychiatric pharmacy residencies, ultimately earning their BCPP and being well positioned to improve mental health care.

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.

Safety of Off-Label Pharmacological Treatment in Pediatric Neuropsychiatric Disorders: A Global Perspective From an Observational Study at an Italian Third Level Children’s Hospital

Background: The acquisition of proper and relevant pediatric clinical data is essential to ensure tolerable and effective pediatric drug therapies. In the field of pharmacological treatment of neuropsychiatric disorders, the lack of sufficient high quality scientific evidence for pediatric age results in the frequent need to prescribe off-label drugs. With the aim of improving knowledge about safety profile of off-label drug prescription in children and adolescent with neurological and/or psychiatric disorders, we realized a multidisciplinary pharmacovigilance study.

Materials and methods: An observational retrospective study was conducted to assess the safety of off-label pharmacological therapies in patients aged 0–18 years, admitted to the Neuropsychiatry Unit of the Institute for Maternal and Child Health - IRCCS “Burlo Garofolo” between January 2016 and December 2018. Prescription patterns and adverse drug reactions were evaluated by a multidisciplinary team.

Results: Overall, 230 patients were enrolled, 48% boys (N = 111), 52% girls (N = 119), average age of 10 years, and a total of 534 prescriptions was analyzed. 54.5% (N = 125) of patients had epilepsy, 37.5% (N = 86) suffered from psychiatric disorders, 8% (N = 19) had other neurological disorders. The prevalence of off-label prescriptions was 32% and 50% of the study population received at least one off-label drug. A total of 106 ADRs was detected: 57% of ADRs were due to drug-drug interactions, 30% were due to off-label prescriptions, 10% were due to overdose and 3% were due to improper use. No significant association between emerged ADRs and off label prescriptions was found (Fisher’s exact two-tailed test, p = 1.000). There was significant association between increasing number of administrated drugs and risk of ADRs (OR 1.99; IC95% 1.58–2.5; p = 0.000). Psychiatric disorders were associated with at least three times higher risk to be treated with an off-label drug (OR 3.30; IC95% 2.26–4.83; p = 0.000).

Conclusions: This study shows that off-label prescribing in neuropsychiatric disorders does not pose a greater risk of ADRs than on-label prescribing and highlights unmet clinical needs in pediatric neuropsychopharmacology. The multidisciplinary approach can provide important contributions to improve therapeutic path of these already complex pathologies by careful monitoring of therapeutic appropriateness and drug interactions.

Impact of a clinical pharmacist on medication safety in mental health Hospital-in-the-Home: a retrospective analysis

BACKGROUND

Integration of clinical pharmacists into multidisciplinary Mental Health Hospital-in-the-Home teams is increasing but little is known about the medication safety contribution these pharmacists make.

AIM

To evaluate whether clinical pharmacist involvement in a Mental Health Hospital-in-the-Home service improved medication safety key performance indicators.

METHOD

Medical records were retrospectively reviewed of all patients admitted to 2 Western Australian Mental Health Hospital-in-the-Home services from September to November 2015. SITE 1: was a 16-bed service incorporating a clinical pharmacist as part of its multidisciplinary team. SITE 2: was a similarly structured 18-bed service but without clinical pharmacist involvement. The primary outcome measure was completion of medication safety key performance indicators obtained from the Western Australian Government Pharmaceutical Review Policy and mental health-specific best practice guidelines.

RESULTS

Key performance indicators from Site 1 (n = 75 records), which incorporated a clinical pharmacist, demonstrated significantly (p < 0.001) higher rates of completion of medication reconciliation [65 (87%) versus 17 (29%)], accurate adverse drug reaction list [73 (97%) versus 34 (58%)], accurate discharge medication list [51 (74%) versus 18 (45%)], accurate medication profile [74 (99%) versus 40 (68%)] and medication chart review [74 (99%) versus 0 (0%)] than Site 2 (n = 59).

CONCLUSION

Integrating a clinical pharmacist into a Mental Health Hospital-in-the-Home program significantly improved achievement of medication safety key performance indicators.

Perspectives of psychiatric patients in rural areas of Jordan: Barriers to compliance and pharmacist role

BACKGROUND

Successful management of psychiatric disorders is affected by patient perspectives and several barriers, that is, conceptual, psychological, social, or logistic reasons that can decrease patient adherence to therapy. In this perspective, pharmacists have a vital role in identifying patients in need of help and in dealing with barriers.

OBJECTIVE

The aim of this study was to investigate perspectives of patients diagnosed with psychiatric disorders, living in rural areas in Jerash, Jordan, regarding their awareness about their conditions, including religious and cultural factors, adherence to their treatment and related barriers, with special focus on pharmacist's role.

METHODS

This cross-sectional survey study was conducted in Jordan from August to November 2019. A validated questionnaire was administered by two pharmacy students via a structured interview with patients waiting for their appointment in the psychiatric clinic. Data were analysed using the Statistical Package for the Social Sciences.

RESULTS

One hundred twenty patients (age 39.4 ± 9.5, 66.7% males) completed the questionnaire. Most of them (71.0%) reported adherence to their medications, and 47.5% reported complete control of their symptoms with treatment. Most patients (59.2%) reported that they perceive their psychiatric problem in terms of religious faith as being counted for their favour in the Hereafter, and 52.5% of them always/usually looked at themselves positively and unaffected by their psychiatric problem; with both factors correlating significantly with better treatment adherence (P < .045 and P < .001; respectively). Barriers affecting adherence included mainly suffering from adverse effects (31.9%) and being unconvinced that they needed a medication (23.3%). Only 14.2% of patients reported that they refer to the pharmacist to get information about their medications.

CONCLUSION

This study shows suboptimal symptom control of psychiatric patients in Jerash. Nonadherence is an issue, with barriers identified. Positive religious and self-image perspectives correlated with better adherence. Patient referral to pharmacists is minimal and needs to be optimised.

Collaboration Between Child and Adolescent Psychiatrists and Mental Health Pharmacists to Improve Treatment Outcomes

Access to mental health care is a long-standing challenge. The high, rising prevalence of mental health disorders and a shortage of mental health professionals has further strained an already fragile system. The clinical pharmacy is underutilized within the mental health space. Interdisciplinary collaboration between child psychiatrists and mental health pharmacists gives the psychiatrist more time for patient evaluation and treatment, while the psychiatric pharmacist provides drug monitoring, medication coordination, and education for providers. This collaborative approach improves outcomes, prevents adverse drug events, reduces hospital stays, lessens emergency department visits, and improves engagement and adherence.

Positive evidence for clinical pharmacist interventions during interdisciplinary rounding at a psychiatric hospital

Clinical pharmacists have not yet become an integral part of interdisciplinary ward rounds in most psychiatric hospitals across the European Union. This retrospective observational pre-post study examined the impact of clinical pharmacist recommendations in an interdisciplinary medical team during psychiatric hospital rounding. The study included all patients in a Slovenian psychiatric hospital who were hospitalized 2019–2020. The clinical pharmacist made 315 recommendations for a total of 224 participants (average age M = 59.4, median = 56). Psychiatrists accepted 295 (93.7%) of the recommendations. After the recommendations, the number of expressed and potential drug-related problems decreased in 166 (93.8%) and 129 (93.8%) interventions, respectively. Three months after discharge, 222 accepted recommendations were continued (70.5%). The most common recommendations were related to antipsychotics (19.4%, N = 61) followed by antidepressants (16.8%, N = 53). Including a clinical pharmacist in the interdisciplinary ward rounds at a psychiatric hospital reduced the number of expressed and potential drug-related problems with a very high recommendation acceptance rate. These results are the first in Central Europe to explore the benefits of including a clinical pharmacist in ward rounding.
