Positive impact of clinical pharmacist interventions on antipsychotic use in patients on excessive polypharmacy evidenced in a retrospective cohort study

Assessment of clinical pharmacist interventions using a web-based application in a Saudi Arabian Tertiary Hospital

Objectives

Medication-related problems are a top concern of clinical pharmacists. Medication-related problems can cause patient harm and increase the number of visits, hospital admissions, and length of hospital stay. The objective was to assess clinical pharmacy medication-related problem-related interventions in a tertiary care setting.

Methods

A retrospective cohort study was conducted at King Fahad Armed Forces Hospital in Jeddah (Saudi Arabia) between June 2021 and June 2022. The data were extracted monthly from a new web-based Microsoft Excel application documenting medication-related problems during any stage of the medication use process.

Results

A total of 5310 medication-related problem-related interventions in 1494 patients were performed. The departments associated with the highest frequency of medication-related problem-related interventions were the critical care unit (26.9%), intensive care unit (23.8%), anticoagulation clinic (17.1%), medical ward (11.3%), and nephrology unit (6.8%). The most common type of medication-related problem-related interventions included inappropriate dosage regimens (25.6%), monitoring drug effect or therapeutic drug monitoring (24.4%), requirement of additional drug therapy (21.9%), and inappropriate drug selection (14.1%). The proposed interventions were accepted by physicians in 97% of the incidents. The most frequent medication classes associated with medication-related problem-related interventions were cardiovascular agents (47.6%), antimicrobial agents (27.2%), and nutrition and blood substitute agents (11.4%). The most frequent medication groups associated with medication-related problem-related interventions were anticoagulants (25.6%) and antibiotics (25.2%).

Conclusions

The current findings characterize the medication-related problem-related interventions addressed in clinical pharmacy at a tertiary care setting. The high rate of physician acceptance emphasizes the integral patient safety role of clinical pharmacy services.

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).

Exploring the Views of Healthcare Professionals Working in a Mental Health Trust on Pharmacists as Future Approved Clinicians

This qualitative research explored the views and attitudes of healthcare professionals towards the role of the mental health pharmacist, and whether this group should be enabled to become approved clinicians (ACs) in England and Wales under the Mental Health Act in future. Following ethical approval, recruitment based on systematic purposive sampling principles took place at one mental health trust in England. Six pharmacists, five medical ACs and two mental health nurses participated in one-to-one digitally audio-recorded semi-structured interviews between June and November 2020. The recordings were transcribed verbatim before being inductively coded and thematically analysed. Notwithstanding the wide recognition among participants of several key skills possessed by mental health pharmacists, various obstacles were identified to them becoming ACs in future, including prevalent conventional models of pharmacy services delivery restricting adequate patient access, as well as insufficient training opportunities to acquire advanced clinical skills, particularly in diagnosis and assessment. In addition to the inherent legislative hurdles, fundamental changes to the skill mix within multidisciplinary mental health teams and improvements to the training of pharmacists were reported by participants to be required to equip them with essential skills to facilitate their transition towards the AC role in future. Further research is needed to gain a better understanding of the challenges facing the clinical development and enhanced utilisation of mental health pharmacists and non-medical ACs across services.

Clinical pharmacist interventions in ambulatory psychogeriatric patients with excessive polypharmacy

Psychogeriatric primary care patients are frequently treated with excessive polypharmacy (≥ 10 medications), leading to complications and increased costs. Such cases are rarely included in treatment guidelines and randomized controlled trials. This paper evaluates the impact of clinical pharmacist medication reviews on the quality of pharmacotherapy in primary care psychogeriatric patients with excessive polypharmacy. The retrospective observational multicentric pre-post study included patients (aged 65 or above) treated with at least one psychotropic and ten or more medications. Clinical pharmacists’ recommendations were retrieved from medication review forms for the period 2012⁠–⁠2014. The study outcome measures were the number of medications, potentially inappropriate medications in the elderly (PIMs), potential drug-drug interactions which should be avoided (pXDDIs), and adherence to treatment guidelines. The study included 246 patients receiving 3294 medications, of which 14.6% were psychotropics. The clinical pharmacists proposed 374 interventions in psychopharmacotherapy. The general practitioners accepted 45.2% of them (169). Accepting clinical pharmacist recommendations reduced the total number of medications by 7.5% from 13.4 to 12.4 per patient (p < 0.05), the total number of prescribed PIMs by 21.8% from 312 to 244 (p < 0.05), the number of pXDDIs by 54.9% from 71 to 31 (p < 0.05) and also improved treatment guidelines adherence for antidepressants and antipsychotics (p < 0.05). Clinical pharmacist interventions significantly improved the quality of psychopharmacotherapy by reducing the total number of medications, PIMs, and pXDDIs. Accepting clinical pharmacist interventions led to better treatment guidelines adherence.

Systematic literature review of pharmacists in general practice in supporting the implementation of shared care agreements in primary care

BACKGROUND

Rising demand for healthcare continues to impact all sectors of the health service. As a result of the growing ageing population and the burden of chronic disease, healthcare has become more complex, and the need for more efficient management of specialist medication across the healthcare interface is of paramount importance. With the rising number of pharmacists working in primary care in clinical roles, is this a role that pharmacists could support to ensure the successful execution of shared care agreement (SCA) in primary care for these patients?

AIM OF THE REVIEW

Systematic review to identify activities and assess the interventions provided by pharmacists in primary care on SCA provision and how it affects health-related quality of life (HRQoL) for patients.

METHOD

Primary studies in English which tested the intervention or obtained views of stakeholders related to pharmacist input to shared care agreement within primary care were included. The following electronic databases were systematically searched from the date of inception to November 2021: AMED®, CINAHL®, Cochrane Database of Systematic Reviews (CDSR), EMBASE®, EMCARE®, Google Scholar, HMIC®, MEDLINE®, PsycINFO®, Scopus and Web of Science®. Grey literature sources were also searched. The search was adapted according to the respective database-specific search tools. It was searched using a combination of Medical Subject Heading terms (MeSH), free-text search terms and Boolean operators.

RESULTS

A total of 5244 titles/abstracts were screened after duplicates were removed, and 64 full articles were assessed for eligibility. On examination of full text, no studies met the inclusion criteria for this review.

CONCLUSION

This review highlights the need for further research to evaluate how pharmacists in general practice can support the safe and effective integration of specialist medication in primary care with the use of SCA.

Clinical pharmacist consultant in primary care settings in Slovenia focused on elderly patients on polypharmacy: successful national program from development to reimbursement

Clinical pharmacists in most primary care settings across Europe do not offer a reimbursed medication review service. This paper describes the development, implementation, and evaluation of a program in Slovenia that allows all general practitioners to refer patients to clinical pharmacists in primary care settings for a medication review. Between 2012 and 2015, the Health Insurance Institute of Slovenia proposed, funded and evaluated a pilot trial and recommended that the service be extended to all public health insurance beneficiaries in Slovenia. Following successful negotiations, the program (Pharmacist Consultant) has been available in all Slovenian primary care settings since 2018. It was evaluated internally with various questionnaires and externally with three studies that reported fewer medication-related problems, fewer drug-drug interactions, cost effectiveness, better treatment guidelines adherence and better humanistic clinical outcomes. The results demonstrate that including clinical pharmacists in primary care settings is particularly beneficial for patients with multiple diseases and medications, who are often elderly people. Future research should examine the service with improved methodologies (e.g., prospective studies with a larger sample size, measures of clinical outcomes and long-term follow-up). In the context of Slovenia, studies should also examine the effects of further integration of clinical pharmacists in patient care (e.g., through patient monitoring, dependent or independent prescribing and medication reviews in hospitals).

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.

Profiles of polypharmacy in older adults and medication associations with signs of aspiration

BACKGROUND

Polypharmacy and specific medication classes are prevalent in older adults. Their relationships with swallowing disorders are not well explored, which would best be managed holistically, with consideration of medication profiles. This study aimed to establish profiles of polypharmacy in older adults and investigate the associations of polypharmacy and medication class with signs of aspiration during swallowing.

METHODS

This was a secondary retrospective analysis of data from 291 adults aged 60 years and older. Polypharmacy was profiled numerically and described. Multivariate logistic regression was used to identify associations between medication classes with signs of aspiration, while controlling for independent variables of demographics, functional status, and medical history.

RESULTS

Three distinct profiles of polypharmacy were described. Higher numbers of medications were associated with higher age, lower functional status, nursing home residency, multimorbidity, and showing signs of aspiration. Thirty-four classes of medications were found in this study, benzodiazepines were the only class independently associated with signs of aspiration.

CONCLUSIONS

Different profiles of polypharmacy can be observed in older adults, but none were independently associated with signs of aspiration. In addition to known demographic and functional status variables, benzodiazepine-use was found to be independently associated with signs of aspiration (p = .005, B = 7.94).

Clinical pharmacist interventions in elderly patients with mental disorders in primary care focused on psychotropics: a retrospective pre-post observational study

BACKGROUND

Mental disorders pose a significant clinical burden and affect approximately one-third of older adults. Although studies have shown positive impacts of clinical pharmacist (CP) interventions within the general population, the long-term effects of such cooperation on geropsychiatric patients in primary care settings are not yet known. This study evaluated whether CP interventions have a long-term impact on the quality of medication prescribing in geropsychiatric patients.

METHODS

We conducted a retrospective non-interventional observational pre-post study for the 2015-2017 period, involving patients aged 65 or above for whom a medication review was provided by a CP. The study included participants with mental disorders treated with polypharmacy, including at least one psychotropic. Potentially inappropriate medications (PIMs) in elderly patients were determined with the Priscus list, and potential type X drug-drug interactions (pXDDIs) with Lexicomp®. Up-to-date treatment guidelines were used to evaluate patient pharmacotherapy, and patient medication was evaluated before the initial medication review and again 6 months later.

RESULTS

The study included 48 patients (79.4 years, SD = 8.13) receiving a total of 558 medications (155 for the treatment of mental disorders). The number of medications decreased by 9.5% after the medication review. The CP proposed 198 interventions related to psychotropics, of which 108 (55%) were accepted by the general practitioners. All accepted (99.1%) interventions except one were still maintained 6 months after the interventions had been proposed. They led to a significant decrease in the total number of medications, PIMs, and pXDDIs (p < 0.05), and improved treatment guidelines adherence.

CONCLUSIONS

CP interventions decreased the number of medications, PIMs, and pXDDIs, and almost all interventions were maintained 6 months later. These results provide evidence for the positive effects of CP interventions in a primary care setting. Additional research with a larger sample size and a randomized study design is needed.
