Implementation of personalized medicine services in community pharmacies: perceptions of independent community pharmacists

Perception of Polish pharmacy students on simulation exercise in pharmaceutical care for diabetes-a pilot study

BACKGROUND

The transformation of a pharmacist's role from that of a drug dispenser to an advisor and patient educator, partially accelerated by the COVID-19 pandemic, requires a thorough change in the pharmacy curriculum. Preparation for the provision of modern pharmaceutical services requires the use of the most advanced teaching methods, such as pharmaceutical simulation. Knowledge alone does not guarantee students' readiness and motivation to take on new challenges in their professional work, but it seems crucial that graduates of medical faculties have the ability to practically apply their knowledge, including in new and nonstandard situations. Therefore, in our study, we proposed an intervention using a simulation method (peer role play) in teaching pharmaceutical care, and we assessed its impact on students' levels of self-perceived confidence and self-efficacy in accordance with Bandura's theory. The aim of the study was to verify whether the introduction of these types of classes could be a useful element of pharmacy curriculum renewal.

METHODS

The questionnaire-based study was conducted during pharmaceutical care peer role-playing classes in a simulation environment with a debriefing session among 85 final-year pharmacy students at Poznan University of Medical Sciences, Poland. The questionnaire consisted of two surveys: the General Self-Efficacy Scale (GSE) and a pre-post self-assessment and self-efficacy questionnaire.

RESULTS

There was a positive correlation between the GSE score and self-efficacy (R = 0.52, p < 0.0001). A statistically significant increase in the post-self-assessment of all the skills and competencies included in the survey in the field of pharmaceutical care of a patient with diabetes compared to the pre-values was also observed (p < 0.001). Additionally, the students' self-efficacy in terms of communicating with patients was greater following the class than before the class (p < 0.001).

CONCLUSIONS

The peer role-play active teaching method was found to be a cost-effective method allowing for an increase in the self-assessment and self-efficacy of pharmacy students in diabetic patient pharmaceutical care. However, further in-depth research is needed to fully confirm the effectiveness of simulation exercises for teaching pharmacy undergraduates.

Knowledge, perceptions, and attitudes toward pharmacogenomics among pharmacists and pharmacy students: A systematic review

Background and Aims

Pharmacists have been recognized as one of the most qualified healthcare professionals in the clinical implementation of pharmacogenomics, yet its widespread implementation in clinical pharmacy practice has remained limited. The review aims to systematically investigate knowledge, perceptions, and attitudes toward pharmacogenomics among pharmacists and pharmacy students to inform the future delivery of pharmacogenomics education programs.

Methods

PubMed, MEDLINE, Embase, Scopus, and the International Pharmaceutical Abstracts were searched up to May 17, 2022. Studies were selected if they included data on pharmacists' or pharmacy students' knowledge, perception, or attitude about pharmacogenomics and were published in a peer-reviewed, English-language journal with full-text availability. Any published study not deemed original research was excluded. All included studies were critically appraised using the Center for Evidence-Based Management's critical appraisal tools. The data were descriptively analyzed and presented based on pharmacists' and pharmacy students' knowledge/awareness, perception/attitudes toward pharmacogenomic (PGx), confidence in using or interpreting PGx testing results, and their desire to get further PGx education or their most preferred method of further education.

Results

A combined total of 12,430 pharmacists and pharmacy students from 26 countries are represented in the 52 included studies. Despite overwhelmingly positive attitudes and perceptions toward pharmacogenomics among pharmacists and pharmacy students, an overall lack of adequate knowledge and confidence was found. The review also found a strong desire for further pharmacogenomics education among pharmacists and pharmacy students.

Conclusion

Pharmacists and pharmacy students have positive perceptions and attitudes toward pharmacogenomics, which is hindered by a lack of knowledge and confidence. However, inadequate control for confounders, limited representativeness of the studied population or region, and small sample sizes diminish the generalizability of the review results. Knowledge and confidence could be improved through enhanced delivery of pharmacogenomic courses within the pharmacy curriculum and continuing education programs.

The Potential Roles of Pharmacists in the Clinical Implementation of Pharmacogenomics

The field of pharmacogenomics is at the forefront of a healthcare revolution, promising to usher in a new era of precision medicine [...].

Are Community Pharmacists Ready to Deliver Pharmacogenomics Testing Services?

This study assesses the readiness and willingness of community pharmacists in England to deliver the pharmacogenomic (PG) testing service. A survey covering demographics and four key themes including awareness and training, general views and experience, barriers, willingness, and confidence was distributed to community pharmacies in the boroughs of Croydon and Sutton in South London. A total of 51 pharmacists responded to the survey. The study revealed that most respondents had a limited familiarity or understanding of pharmacogenomics (n = 32, 63%). Moreover, on average, around 60% of participants were unable to accurately identify drugs that currently have or could have potentials for PG testing. They indicated that their pharmacogenomic education and training is inadequate, with only 2/51 pharmacists reported receiving relevant training. Time constraints, shortage of staff and lack of knowledge were identified as barriers that could hinder the implementation of PG. Over 60% of respondents expressed willingness to provide PG testing service after receiving adequate training. The study found that currently not all community pharmacists are prepared to provide PG testing services, with newly qualified pharmacists appearing to have an upper hand when it comes to understanding the subject. Therefore, consistent, and uniform training is required to allow community pharmacists with all years of experience to equally contribute to the implementation of PG testing.

The Critical Role of Pharmacists in the Clinical Delivery of Pharmacogenetics in the U.S

Since the rebirth of pharmacogenomics (PGx) in the 1990s and 2000s, with new discoveries of genetic variation underlying adverse drug response and new analytical technologies such as sequencing and microarrays, there has been much interest in the clinical application of PGx testing. The early involvement of pharmacists in clinical studies and the establishment of organizations to support the dissemination of information about PGx variants have naturally resulted in leaders in clinical implementation. This paper presents an overview of the evolving role of pharmacists, and discusses potential challenges and future paths, primarily focused in the U.S. Pharmacists have positioned themselves as leaders in clinical PGx testing, and will prepare the next generation to utilize PGx testing in their scope of practice.

Mapping the implementation of pharmacogenomic testing in community pharmacies 2003-2021 using the Theoretical Domains Framework: A scoping review

BACKGROUND

Pharmacogenetic (PGx) testing is an evidence-based approach to finding effective medication therapies. While community pharmacists are ideally situated to provide PGx testing, the extent of its implementation is limited within community pharmacies.

OBJECTIVE

This study aimed to explore trends in the international peer-reviewed primary literature on community pharmacists' implementation of PGx and map the main findings on the Theoretical Domains Framework (TDF).

METHODS

A literature search and 2-step screening were conducted per PRISMA Extension for Scoping Reviews. Inclusion criteria were English language, community pharmacy setting, full papers, and empirical research. Data were collated in a data extraction form. The main findings were deductively mapped on the TDF with a content analysis approach.

RESULTS

Of 1176 identified documents screened, 39 were included in this scoping review. Four groups of research were identified: pre-implementation surveys (interviews, and focus groups [56%, n = 22]); PGx implementation (single cohort to assess feasibility [38%, n = 15]); PGx implementation (controlled study to assess feasibility [n = 1, 2.5%]); and efficacy of PGx (2.5%, n = 1). Most studies throughout the 4 groups sought pharmacists' perceptions (46%, n = 18) and used the quantitative paradigm (77%, n = 30). TDF mapping documented positive beliefs about the benefits of PGx testing as a part of the pharmacists' role. Barriers to PGx use included pharmacists' awareness of knowledge gaps, low confidence in interpreting and communicating PGx results, concerns about cost, privacy, and integration into pharmacy workflow.

CONCLUSION

Research addressing PGx implementation within the community pharmacy evolved from assessing individuals' perceptions of PGx to determining the feasibility of PGx testing in pharmacies and evaluating the impact of PGx testing on patient outcomes in depression. Mapping the main findings on the TDF facilitates the development of multidimensional interventions, potentially targeting patients, pharmacists, and health policy.

Feasibility of Community Pharmacist-Initiated and Point-of-Care CYP2C19 Genotype-Guided De-Escalation of Oral P2Y12 Inhibitors

Tailoring antiplatelet therapy based on CYP2C19 pharmacogenetic (PGx) testing can improve cardiovascular outcomes and potentially reduce healthcare costs in patients on a P2Y12-inhibitor regime with prasugrel or ticagrelor. However, ubiquitous adoption—particularly in an outpatient setting—remains limited. We conducted a proof-of-concept study to evaluate the feasibility of CYP2C19-guided de-escalation of prasugrel/ticagrelor to clopidogrel through point-of-care (POC) PGx testing in the community pharmacy. Multiple feasibility outcomes were assessed. Overall, 144 patients underwent CYP2C19 PGx testing in 27 community pharmacies. Successful test results were obtained in 142 patients (98.6%). De-escalation to clopidogrel occurred in 19 patients (20%) out of 95 (67%) eligible for therapy de-escalation, which was mainly due to PGx testing not being included in cardiology guidelines. Out of the 119 patients (84%) and 14 pharmacists (100%) surveyed, 109 patients (92%) found the community pharmacy a suitable location for PGx testing, and the majority of pharmacists (86%) thought it has added value. Net costs due to PGx testing were estimated at €43 per patient, which could be reduced by earlier testing and could turn into savings if de-escalation would double to 40%. Although the observed de-escalation rate was low, POC CYP2C19-guided de-escalation to clopidogrel appears feasible in a community pharmacy setting.

Clinical Knowledge, Attitude, and Perceptions of Community Pharmacists Towards Pharmacogenomics - A Cross-Sectional Study from Saudi Arabia

Background and Aims

It is crucial to provide healthcare personnel with the necessary knowledge and understanding of genetic testing and pharmacogenomics. The purpose of this study is to assess the knowledge, attitudes, views, and considerations of Community pharmacists (CPs) about pharmacogenomics and genetics.

Methods and Materials

A cross-sectional web-based study was conducted among practicing pharmacists Between January and February of 2022. Participants were recruited through a convenient sampling technique. A total of 23 item questionnaires were used to assess the Knowledge Attitudes, Views, and Considerations toward Pharmacogenomics among pharmacists.

Results

The mean age of the CPs were 28.45±7.29(Std). Among the CPs, 38.4% (98 of 255) of them were correctly identified human chromosomes, and the majority of them 73.3% knew that adverse reactions can be caused by genetic changes in the human body. A total of 194 CPs agreed that certain drugs can be affected by genetic changes in the patient. In this study, one-third (33%) of the CPs were found to have good knowledge, while most (66.3%) of the CPs were found poor knowledge of pharmacogenomics and genetics. Furthermore, the knowledge score is significantly different concerning the qualification of the CPs (p=0.0001).

Conclusion

The current findings, demonstrated a majority of the CPs found a lack of knowledge and understanding regarding pharmacogenomics and its perspectives, there is a need to increase awareness among CPs to reduce the knowledge gap of pharmacogenomics and genetics.

Public perceptions of pharmacogenomic services in Ireland - Are people with chronic disease more likely to want service availability than those without? A questionnaire study

Background

As pharmacogenomic services begin to emerge in primary care, the insight of the public is crucial for its integration into clinical practice.

Objectives

To establish perceptions of pharmacogenomics (awareness, understanding, openness to availability, perceived benefits and concerns, willingness to pay, and service setting) and investigate if they differ between those with and without chronic disease(s).

Methods

An anonymous, online questionnaire generated using Qualtrics® and circulated via social media and posters placed in eight participating community pharmacies was conducted with Irish adults. The questions were designed to consider existing literature on patient perceptions of pharmacogenomics. Descriptive statistics were used to summarize questionnaire responses. Chi-square test was used to compare categorical variables, while independent sample t-test and one-way ANOVA were used to compare the mean values of two (with and without chronic disease) and three groups (multimorbidity (two or more chronic conditions) and polypharmacy (prescribed four or more regular medicines) (MMPP), a single chronic disease, and those without existing medical conditions) respectively Logistic regression was used to evaluate age and gender adjusted associations of chronic disease(s) with responses. A p-value <0.05 was considered statistically significant.

Results

A total of 421 responses were received, 30% (n = 120) of whom reported having a chronic disease. Overall, respondents reported low awareness (44%, n = 166) and poor knowledge (55%, n = 212) of pharmacogenomics. After explaining pharmacogenomics to respondents, patients with chronic disease(s) were 2.17 times more likely (p < 0.001) to want pharmacogenomic services availability than those without existing conditions, adjusted for age and gender (driven by preferences of those with MMPP than those with single chronic disease). Respondents demonstrated a high level of interest and noted both the potential benefits and downsides of pharmacogenomic testing. Willingness-to-pay was not associated with having a chronic disease and respondents were more positive about primary care (community pharmacy or general practice) rather than hospital-based pharmacogenomics implementation.

Conclusion

The Irish public in general and those with chronic disease in particular are strongly supportive of pharmacogenomic testing, highlighting an unmet need for its incorporation in medicines optimization. These data underline the need for more research on the implementation of community-based pharmacogenomics services for MMPP patients and ubiquitous pharmacogenomics education programs.

Knowledge and attitudes of incoming pharmacy students toward pharmacogenomics and survey reliability

Aims: To assess knowledge and attitudes toward pharmacogenomics (PGx) of incoming doctoral pharmacy students, to evaluate the internal structure and reliability of the PGx survey and to identify variables associated with the different responses. Methods: A PGx survey based on the core pharmacist competencies in PGx was created. Results: Of 83.2% analyzable responses, 91% believed PGx is a useful tool and relevant to future practice but over 70% stated they lack confidence in clinical PGx knowledge. This 38-item PGx survey included three factors showing high reliability. Prior genetic/PGx testing and unsatisfactory medication experiences were associated with a more positive attitude toward PGx. Conclusion: The majority of students have positive attitudes toward PGx, but lack knowledge in genetic concepts and clinical PGx.

Pharmacogenomics: a tool to improve medication safety and efficacy in patients with cystic fibrosis

Cystic fibrosis is a genetic, multiorgan system disease that involves the use of many medications to control symptoms associated with the underlying condition. Many of these medications have Clinical Pharmacogenetics Implementation Consortium evidence-based guidelines for pharmacogenomics that are available to guide dosing. The aim of this article is to review relevant literature and evaluate the utility of preemptive pharmacogenomics testing for persons with cystic fibrosis and propose a pharmacogenomics panel that could be considered standard of care for persons with cystic fibrosis.

Knowledge, attitude and perception of community pharmacists towards pharmacogenomics services in northern Nigeria: a cross-sectional study

Objectives

To evaluate knowledge, attitude and perception of community pharmacists towards pharmacogenomics services.

Methods

A cross-sectional study was conducted among community pharmacists in two cities in Northern Nigeria using a self-administered, validated and pre-tested questionnaire. The data were collected from December 2021 to February 2022 and were analysed using both descriptive and inferential analyses.

Results

A total of 161 completed questionnaires were included in this study (response rate was 61.9%). Most of the respondents were males (59.0%). Only 25.5% had previous pharmacogenomics training but 90.1% indicated an interest in attending pharmacogenomics training in the future. Overall, respondents had moderate knowledge of pharmacogenomics with higher knowledge score found among those who had previous pharmacogenomics training (11.9 ± 1.7 vs 10.5 ± 2.4; p = 0.001), and those with postgraduate qualification (11.7 ± 1.9 vs 10.7 ± 2.3; p = 0.028). The mean attitude score was 6.8 ± 2.0 out of 10.0 indicating a good attitude towards pharmacogenomics services. Those with previous training (8.1 ± 1.7 vs 6.2 ± 1.9; p < 0.001) and those with postgraduate qualification (7.2 ± 2.3 vs 6.6 ± 1.9; p = 0.042) had better attitude towards pharmacogenomics services. The median perception score was 34.0 out of 45.0, indicating a positive perception towards pharmacogenomics. There was a better perception among those with previous pharmacogenomics training (40.0 [21–45] vs 34.0 [0–45]; p = 0.002) and those with postgraduate qualifications (39.0 [0–45] vs 34.0 [21–45]; p = 0.010). Barriers to the implementation of pharmacogenomics included lack of knowledge (89.4%), lack of guidelines (87.5%) and lack of reimbursement (81.4%).

Conclusion

Community pharmacists have a moderate knowledge, a good attitude and a positive perception towards pharmacogenomics services. Those with previous pharmacogenomics training and those with postgraduate qualifications had better knowledge, attitude and perception towards pharmacogenomics services. Lack of knowledge, lack of guidelines and lack of reimbursement were the major barriers to the implementation of pharmacogenomics services in community pharmacies in Nigeria. Pharmacogenomics should be included in pharmacy training curricula to prepare pharmacists for the provision of pharmacogenomics services. Development of local guidelines and a robust reimbursement plan for pharmacogenomics services is recommended.

Opportunities for extended community pharmacy services in United Arab Emirates: perception, practice, perceived barriers and willingness among community pharmacists

Background

Community pharmacies are widely distributed in the United Arab Emirates where community pharmacists’ (CPs’) perspectives on provision of extended community pharmacy services (ECPS) is not known. This study assessed CPs perception, practices, perceived barriers and willingness to provide ECPS.

Methods

A descriptive cross-sectional survey using a self-administered Likert-type questionnaire (Cronbach alpha = 0.976) was conducted among 195 community CPs in Northern emirates, selected through multistage sampling technique. The filled questionnaires were assessed for CPs’ perception, practice, perceived barriers and willingness to perform ECPS. Mann–Whitney and Kruskal–Wallis tests examined the association between demography and outcome variables (alpha value of 0.05) with further analysis using Dunn’ post hoc test.

Results

Of the respondents, 71.8% (n = 140) ‘strongly agreed’ that every CP must provide ECPs and 39% (n = 76) ‘strongly agreed’ in supporting ECPS with another 44.1% (n = 86) ‘agreed’ on the same. The major barriers felt by CPs in practicing ECPS were lack of incentive for employee pharmacists [3 (2–3)], lack of documentation [3 (2–3)], insufficient time [3 (2–3)] and lack of patients’ demand [(2–3)]; maximum score (5–5). CPs also responded ‘completely’ willing to provide services such as blood pressure measurement, pregnancy testing and BMI measurement. Pharmacy location influenced practice score (p = 0.008) and access to the internet had a significant effect on barriers score (p = 0.000). Availability of drug information sources impacted perception (p = 0.038), practice (p = 0.000) and willingness scores (p = 0.011).

Conclusions

CPs’ perception on providing ECPS was positive and they are currently offering ECPS within their available resources and facilities. Less demand from patients and lack of time were reportedly the major barriers in offering ECPS. Proper utilization of CPs in providing ECPS can complement the healthcare system with additional cost and time savings for the patients.

Co-designing a community pharmacy pharmacogenomics testing service in the UK

Introduction

Pharmacogenomics (PGx) testing services have been delivered through community pharmacies across the globe, though not yet in the UK. This paper is reporting a focus group study, the first stage of a participatory co-design process to increase the chance of a successful implementation of a PGx service through community pharmacy in the UK.

Aim

To identify the barriers and enablers to implementing a community pharmacy based PGx service in the UK.

Method

Three focus groups were conducted with community pharmacists (n = 10), prescribers (n = 8) and patients (n = 8) in England. The focus groups were recorded, transcribed and thematically analysed using the Braun and Clarke six phase reflexive thematic analysis approach.

Results

The analysis identified five themes about PGx testing in community pharmacies: (1) In- principle receptiveness, (2) Appreciation of the benefits, (3) Lack of implementation resources (4) Ambiguity about implications for implementation and (5) Interprofessional relationship challenges.

Conclusion

The identified enablers for implementation of a PGx service were at a macro health system strategic level; the concerns were more at a granular operational procedural level. Overall receptiveness was noted by all three participant groups, and both prescriber and pharmacist groups appreciated the potential benefits for patients and the healthcare system. Prior to implementation in the UK, there is a need to disambiguate health professional’s concerns of the guidance, resources, and knowledge required to set up and deliver the service and to resolve patient concerns about the nature of genomics.

Pharmacogenetic interventions to improve outcomes in patients with multimorbidity or prescribed polypharmacy: a systematic review

Conventional medicines optimisation interventions in people with multimorbidity and polypharmacy are complex and yet limited; a more holistic and integrated approach to healthcare delivery is required. Pharmacogenetics has potential as a component of medicines optimisation. Studies involving multi-medicine pharmacogenetics in adults with multimorbidity or polypharmacy, reporting on outcomes derived from relevant core outcome sets, were included in this systematic review. Narrative synthesis was undertaken to summarise the data; meta-analysis was inappropriate due to study heterogeneity. Fifteen studies of diverse design and variable quality were included. A small, randomised study involving pharmacist-led medicines optimisation, including pharmacogenetics, suggests this approach could have significant benefits for patients and health systems. However, due to study design heterogeneity and the quality of the included studies, it is difficult to draw generalisable conclusions. Further pragmatic, robust pharmacogenetics studies in diverse, real-world patient populations, are required to establish the benefit of multi-medicine pharmacogenetic screening on patient outcomes.

Pharmacists as Personalized Medicine Experts (PRIME): Experiences Implementing Pharmacist-Led Pharmacogenomic Testing in Primary Care Practices

Research exploring the integration of pharmacogenomics (PGx) testing by pharmacists into their primary care practices (including community pharmacies) has focused on the “external” factors that impact practice implementation. In this study, additional “internal” factors, related to the capabilities, opportunities, and motivations of pharmacists that influence their ability to implement PGx testing, were analyzed. Semi-structured interview data from the Pharmacists as Personalized Medicine Experts (PRIME) study, which examined the barriers and facilitators to implementing PGx testing by pharmacists into primary care practice, were analyzed. Through thematic analysis, using the theoretical domains framework (TDF) domains as deductive codes, the authors identified the most relevant TDF domains and applied the behavioural change wheel (BCW) to generate intervention types to aid in the implementation of PGx testing. Pharmacists described how their professional identities, practice environments, self-confidence, and beliefs in the benefits of PGx impacted their ability to provide a PGx-testing service. Potential interventions to improve the implementation of the PGx service included preparing pharmacists for managing an increased patient load, helping pharmacists navigate the software and technology requirements associated with the PGx service, and streamlining workflows and documentation requirements. As interest in the wide-scale implementation of PGx testing through community pharmacies grows, additional strategies need to address the “internal” factors that influence the ability of pharmacists to integrate testing into their practices.

A systematic review of pharmacogenetic testing in primary care: Attitudes of patients, general practitioners, and pharmacists

BACKGROUND

Pharmacogenetic testing enhances patient safety by improving medical treatment and reducing side effects. It has shown potential in both primary and secondary care. However, implementation in healthcare, particularly in primary care, is slow.

OBJECTIVE

The objective was to review articles published on the attitudes towards, and knowledge on pharmacogenetic testing in primary care, among general practitioners, pharmacists, and patients.

METHODS

The review was performed according to the PRISMA checklist. A systemized literature search was followed by a 2-step screening process. Apart from the content of articles being within the scope of the review, inclusion criteria included: articles in English; primary research articles; qualitative, quantitative, or mixed methods. Content analysis was conducted as a qualitative meta-synthesis. The methodological rigor of included articles was assessed.

RESULTS

Fifteen studies were included. The analysis resulted in the following main themes: i) benefits of pharmacogenetic testing, ii) barriers to pharmacogenetic testing, iii) pharmacists' role in pharmacogenetic counselling, and iv) pharmacists' knowledge on pharmacogenetics. Methodological rigor was generally medium/high.

CONCLUSIONS

More studies are needed in this area, and there is a need for more education on pharmacogenetic testing for healthcare professionals. Issues like patient autonomy, economy, and access to tests also need to be addressed.

A Comprehensive Review of HLA and Severe Cutaneous Adverse Drug Reactions: Implication for Clinical Pharmacogenomics and Precision Medicine

Human leukocyte antigen (HLA) encoded by the HLA gene is an important modulator for immune responses and drug hypersensitivity reactions as well. Genetic polymorphisms of HLA vary widely at population level and are responsible for developing severe cutaneous adverse drug reactions (SCARs) such as Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), maculopapular exanthema (MPE). The associations of different HLA alleles with the risk of drug induced SJS/TEN, DRESS and MPE are strongly supportive for clinical considerations. Prescribing guidelines generated by different national and international working groups for translation of HLA pharmacogenetics into clinical practice are underway and functional in many countries, including Thailand. Cutting edge genomic technologies may accelerate wider adoption of HLA screening in routine clinical settings. There are great opportunities and several challenges as well for effective implementation of HLA genotyping globally in routine clinical practice for the prevention of drug induced SCARs substantially, enforcing precision medicine initiatives.

Assessment of the need for pharmacogenomics education among pharmacists in the West Bank of Palestine

BACKGROUND

Pharmacogenomics testing aims to optimise therapy and reduce the inter-individual variation in drug response. One of the major barriers against the implementation of pharmacogenomics testing is the low level of knowledge on the topic.

AIMS

This study aimed to evaluate the need for pharmacogenomics education among pharmacists in the West Bank of Palestine.

METHODS

This study was cross-sectional and included 370 pharmacists, among different cities in the West Bank of Palestine between October and December 2020. The questionnaire consisted of 25 close-ended questions that evaluated the exposure to pharmacogenomics education, attitude toward the role of pharmacogenomics testing in clinical practice and self-capability of pharmacists in pharmacogenomics testing.

RESULTS

It was found that 60% of the respondents disagreed that pharmacogenomics was an integral part of the pharmacy school curriculum and/or experiential education. The vast majority of the respondents (94%) agreed that pharmacists should be required to have some knowledge of pharmacogenomics. The majority of the respondents (88.6%) believe that pharmacogenomics testing will improve pharmacists' ability to more effectively control drug therapy expenditures. However, only 38% of the respondents could identify medications that require pharmacogenomics testing, and only 35.1% could identify reliable sources of information regarding pharmacogenomics for healthcare providers and patients.

CONCLUSION

It is seen from the results of this study that there is a high need to learn about pharmacogenomics testing, which can help the pharmacists make pharmacotherapy decisions. Additionally, current pharmacists have low self-confidence in making decisions depending on the results of pharmacogenomics testing. It is recommended to increase the exposure of pharmacogenomics knowledge by including the subject in courses and workshops in pharmacy school curricula in the West Bank of Palestine.

Patients' and professionals' views related to ethical issues in precision medicine: a mixed research synthesis

BACKGROUND

Precision medicine development is driven by the possibilities of next generation sequencing, information technology and artificial intelligence and thus, raises a number of ethical questions. Empirical studies have investigated such issues from the perspectives of health care professionals, researchers and patients. We synthesize the results from these studies in this review.

METHODS

We used a systematic strategy to search, screen and assess the literature for eligibility related to our research question. The initial search for empirical studies in five data bases provided 665 different records and we selected 92 of these publications for inclusion in this review. Data were extracted in a spreadsheet and categorized into different topics representing the views on ethical issues in precision medicine.

RESULTS

Many patients and professionals expect high benefits from precision medicine and have a positive attitude towards it. However, patients and professionals also perceive some risks. Commonly perceived risks include: lack of evidence for accuracy of tests and efficacy of treatments; limited knowledge of patients, which makes informed consent more difficult; possible unavailability of access to precision medicine for underprivileged people and ethnic minorities; misuse of data by insurance companies and employers, potential of racial stigmatization due to genetic information; unwanted communication of incidental findings; changes in doctor-patient-relationship through focusing on data; and the problem that patients could feel under pressure to optimize their health.

CONCLUSIONS

National legislation and guidelines already minimize many risks associated with precision medicine. However, from our perspective some problems require more attention. Should hopes for precision medicine's benefits be fulfilled, then the ethical principle of justice would require an unlimited access to precision medicine for all people. The potential for autonomous patients' decisions must be greatly enhanced by improvements in patient education. Harm from test results must be avoided in any case by the highest possible data security level and communication guidelines. Changes in the doctor-patient relationship and the impact of precision medicine on the quality of life should be further investigated. Additionally, the cost-effectiveness of precision medicine should be further examined, in order to avoid malinvestment.

Independent Community Pharmacists' Experience in Offering Pharmacogenetic Testing

Objective

This study assessed pharmacist experiences with delivering pharmacogenetic (PGx) testing in independent community pharmacies.

Methods

We conducted a cluster randomized trial of independent community pharmacies in North Carolina randomized to provide either PGx testing as a standalone service or integrated into medication therapy management (MTM) services. Surveys and pharmacist data about the delivery of PGx testing were collected. Semi-structured interviews were also conducted.

Results

A total of 36 pharmacists participated in the study from 22 pharmacies. Sixteen pharmacists completed the pre-study and post-study surveys, and four pharmacists completed the semi-structured interviews. Thirty-one percent (11/36) of pharmacists had had some education in personalized medicine or PGx prior to the study. The only outcome that differed by study arm was the use of educational resources, with significantly higher utilization in the PGx testing only arm (p=0.007). Overall, compared to the pre-study assessment, pharmacists' knowledge about PGx significantly improved post-study (p=0.018). In the post-study survey, almost all pharmacists indicated that they felt qualified/able to provide PGx testing at their pharmacy. While 75% of pharmacists indicated that they may continue to provide PGx testing at their pharmacy after the study, the major concerns were lack of reimbursement for PGx counseling and consultation given the necessary time required.

Conclusion

Our findings demonstrated a positive experience with delivering PGx testing in the community pharmacy setting with little difference in pharmacists' experiences in providing PGx testing with or without MTM. Pharmacists were confident in their ability to provide PGx testing and were interested in continuing to offer testing, though sustained delivery may be challenged by lack of prescribing provider engagement and reimbursement.

Delivery of Pharmacogenetic Testing with or without Medication Therapy Management in a Community Pharmacy Setting

Objective

The delivery of pharmacogenetic (PGx) testing has primarily been through clinical and hospital settings. We conducted a study to explore the feasibility of delivering PGx testing through community pharmacies, a less-studied setting.

Methods

We conducted a cluster randomized trial of community pharmacies in North Carolina through two approaches: the provision of PGx testing alone or PGx testing with medication therapy management (MTM).

Results

A total of 150 patient participants were enrolled at 17 pharmacies and reported high satisfaction with their testing experience. Participants in the PGx plus MTM arm were more likely to recall a higher number of results (p=0.04) and more likely to clearly understand their choices for prevention or early detection of side effects (p=0.01). A medication or dose change based on the PGx results was made for 8.7% of participants.

Conclusion

Limited differences were observed in the provision of PGx testing as a standalone test or combined with MTM. A limited number of treatment changes were made based on PGx test results. Patient acceptance of PGx testing offered through the community pharmacy was very high, but the addition of MTM did not impact patient-reported perceptions about PGx testing or medication adherence.

Factors influencing the implementation of pharmaceutical care in outpatient settings: A systematic review applying the Consolidated Framework for Implementation Research

BACKGROUND

Pharmaceutical care in outpatient settings is a type of health service that has been shown to contribute to decreasing drug-related morbidity and mortality rates. However, every process of implementing a new service brings about changes and transformations in the work routine, thus posing challenges.

OBJECTIVES

This systematic review aims to identify barriers to and facilitators for the implementation of pharmaceutical care in outpatient settings by applying the CFIR method, a framework based on the theory of health services, used to analyze and synthesize research data, which can direct strategies for the service to work as planned.

METHODS

A systematic review was conducted exploring the barriers to and facilitators for the implementation of pharmaceutical care in outpatient settings. The MEDLINE, EMBASE, CINAHL, COCHRANE, and LILACS databases were consulted.

RESULTS

Eight studies were included: five qualitative ones, two mixed-method ones, and a quantitative one. The most frequent CFIR constructs identified were Patient Needs and Resources (n = 30, 10.75%), Knowledge and Beliefs about the Intervention (n = 31, 11.11%), Networks and Communications (n = 34, 12.19%), and Available Resources (n = 56, 20.07%). The most cited barriers were: insufficient human resources, patients' unawareness of the existence of the pharmaceutical care service, and pharmacists' resistance to changes. Facilitators included: the opportune presentation of the service to the healthcare team; the use of electronic devices for specific guidance; and the assessment of patient satisfaction.

CONCLUSIONS

This systematic review allowed detecting key guidelines to improve the implementation process, including (1) defining an implementation method and exploring it extensively during the pre-implementation phase, (2) ensuring human and financial resources, (3) determining how the new service will interact with other existing services. More research is needed to understand how these factors can affect the implementation of clinical services.

Perceptions and Attitudes of Pharmacogenomics Through the Lens of Community Pharmacists and Patients

Background Pharmacists represent some of the most accessible healthcare workers and are in an opportune position to spearhead new clinical initiatives, such as pharmacogenomics (PGx) services. It is important that we understand the perceptions and attitudes both pharmacists and patients have regarding PGx and potential barriers of implementing it into routine clinical practice. Methods A cross-sectional survey study was conducted across one regional division of a large community pharmacy chain to assess the perceptions and attitudes of pharmacists and patients regarding PGx in California. A secondary aim was to determine perceived barriers to PGx implementation into community pharmacies. Results The majority (67%) of pharmacists agreed or strongly agreed to understanding PGx compared to 35% of patients being aware of PGx (p<0.001). More patients (62%) preferred their pharmacist compared to pharmacists (43%) preferring themselves as a provider to manage patients' medications based on their PGx results (p<0.01). Many patients (88%) expressed interest in participating in a PGx test; both pharmacists (84%) and patients (85%) were unlikely to have participated or know someone who has participated in PGx testing. Pharmacists and patients expressed similar concerns about privacy of their PGx data by employers (p=0.287) and insurers (p=0.953), a potential barrier to PGx implementation. Conclusion Pharmacists are well positioned to spearhead PGx consultations and patients are interested in pharmacists using PGx to help manage their medications; however, various barriers were identified that must be overcome for PGx to become incorporated in routine practice.

Pharmacogenomics in the United States Community Pharmacy Setting: The Clopidogrel-CYP2C19 Example

Pharmacogenomics (PGx) is expanding across health-care practice settings, including the community pharmacy. In the United States, models of implementation of PGx in the community pharmacy have described independent services and those layered on to medication therapy management. The drug-gene pair of clopidogrel-CYP2C19 has been a focus of implementation of PGx in community pharmacy and serves as an example of the evolution of the application of drug-gene interaction information to help optimize drug therapy. Expanded information related to this drug-gene pair has been provided by the US Food and Drug Administration and clinical PGx guidelines have and continue to be updated to support clinical decision-making. Most recently direct-to-consumer (DTC) PGx has resulted in patient generated sample collection and submission to a genetic testing-related company for analysis, with reporting of genotype and related phenotype information directly to the patient without a health-care professional guiding or even being involved in the process. The DTC testing approach needs to be considered in the development or modification of PGx service models in the community pharmacy setting. The example of clopidogrel-CYP2C19 is discussed and current models of PGx implementation in the community pharmacy in the United States are presented. New approaches to PGx services are offered as implementation continues to evolve and may now include DTC information.

Implementation of clinical pharmacy services using problematization with Maguerez Arc: A quasi-experimental before-after study

RATIONALE, AIMS, AND OBJECTIVES

The growth of clinical pharmacy services (CPS) has positively impacted clinical, economic, and humanistic health outcomes. However, detailed studies on the process of implementing CPS in healthcare systems are incipient. Thus, the present study aimed to evaluate the CPS implementation in certain public health units in a metropolis in northeast Brazil.

METHODS

A quasi-experimental before-and-after study was carried out in Recife City, from July 2015 to March 2016. The study was carried out using the Methodology of Problematization with Maguerez Arc and was divided into: initial evaluation (before), planning, interventions, and preliminary evaluation (after). The participants were pharmacists, patients, health professionals, and local health managers. Descriptive statistics were used to report data. The statistical significance of the comparison between variables was evaluated using the Wilcoxon test (95% CI; P ≤ .05).

RESULTS

Initial evaluation: Identified incipient CPS, a lack of structure and work process of pharmacists. Planning: Sixteen brainstorming meetings were held with the different actors resulting in a strategic plan.

INTERVENTION

Twenty-two political-administrative meetings were held with managers and health teams and 768 hours of theoretical and practical training with mentoring for pharmacists. Preliminary evaluation: Structure indicators presented a statistically significant difference, differently from the process indicators. Pharmacists attended 842 patients and performed 1465 pharmaceutical consultations in 6 months. Regarding the outcome indicators, it was possible to identify changes in the clinical status of the most prevalent diseases among those patients who attended three pharmaceutical consultations.

CONCLUSIONS

It was possible to evaluate the CPS implementation in certain public health units in a metropolis in Brazil, through the Methodology of Problematization with Maguerez Arc. This methodology may be part of models for future implementations of CPS in health systems.

A state-level needs analysis of community pharmacy point-of-care testing

Background

The uptake of point-of-care testing (POCT) within community pharmacies at state and national levels is largely unknown despite the endorsement and advocacy efforts of pharmacy organizations, recent legislative advances, and numerous models for successful POCT implementation within individual pharmacy sites.

Objectives

The study aimed to describe the current landscape of POCT in Wisconsin community pharmacies and identify opportunities for the advancement of testing and the key factors influencing the realization of these opportunities.

Methods

A survey was administered over the telephone to pharmacy managers of community pharmacies in Wisconsin. The sites were randomly selected from predefined geographic regions to mirror pharmacy distribution across Wisconsin. The survey items evaluated provision of POCT, future direction of POCT, barriers and motivators to offering POCT, and pharmacy demographics. Descriptive statistics and thematic analysis were used to analyze data.

Results

Pharmacy managers from 147 of the 938 registered community pharmacies (15.7%) participated in the survey. Only 17.1% of the pharmacies were offering POCT; however, 48.3% of managers reported that their pharmacy would likely implement or expand POCT within the next 5 years. The most commonly reported barriers to initiating or expanding POCT were the limitations on pharmacist availability to oversee testing and workflow restrictions. Continuing to advance the pharmacy profession was a top reason for offering or expanding testing services.

Discussion

While few pharmacies are offering POCT in Wisconsin, there is motivation for expansion in coming years. Understanding, anticipating and addressing common barriers can faciliate this process.

Conclusion

This needs analysis offers a blueprint for researchers, educators, and clinicians to shape POCT efforts by examining the landscape of pharmacy-based testing in their own states and communities.

Patient perceptions of pharmacogenomic testing in the community pharmacy setting

BACKGROUND

In order to optimize community pharmacist roles and patient outcomes, a better understanding of patient perceptions of pharmacogenomic (PGx) testing may be helpful for successful integration into community pharmacy practice.

OBJECTIVE

The objective of this study was to identify patient perceptions related to PGx testing in the community pharmacy setting.

METHODS

Semi-structured, face-to-face interviews were conducted with adults ≥18 years of age to gather their perceptions of PGx testing. Interview participants were taking either an antiplatelet agent or a selective serotonin reuptake inhibitor listed in Clinical Pharmacogenetics Implementation Consortium (CPIC) guidelines and were patients at one of two community pharmacies in West Michigan. Interview questions were designed to follow the Theory of Planned Behavior and to take into account existing literature on patient perceptions of PGx. Interviews were recorded, transcribed by a third party transcription service, coded by a team of three researchers to identify themes, and analyzed using nVivo qualitative analysis software.

RESULTS

A total of 19 interviews were conducted over a period of 16 days in June 2016. Upon preliminary evaluation, four themes related to patient perceptions of PGx testing were consistently observed across multiple interviews: 1) trust, 2) experience, 3) risk/benefit, and 4) clarity.

CONCLUSIONS

Semi-structured patient interviews revealed four themes related to PGx testing in the community pharmacy setting. These themes may influence the desire to pursue PGx testing. Future research may seek to identify how community pharmacists can communicate with patients about PGx in the context of these themes to empower patients to make positive health care decisions.

Factors influencing the implementation of clinical pharmacy services for hospitalized patients: A mixed-methods systematic review

BACKGROUND

Despite the evidence of benefits, clinical pharmacy services (CPS) are not uniformly implemented across healthcare institutions. Understanding the influencing factors and identifying the domains in which they act is the first step to a successful implementation.

OBJECTIVE

To identify the factors that affect the implementation of CPS for inpatients and to categorize them.

METHODS

Cochrane Library, Embase, CINAHL, IPA, Medline/PubMed, and Lilacs databases were researched up until January 2018. The search strategy was developed using text words or MESH terms related to the following four domains: "clinical pharmacy," "influencing factors," "implementation," and "hospital." Two reviewers selected original research articles that reported the factors influencing the implementation of CPS in hospitals, extracted data, and assessed the quality of the studies. After framework synthesis and categorization of the factors, a diagrammatic approach was used to present the results.

RESULTS

Fifty-three factors were identified in the 21 studies that were included in this review. The most cited influencing factors were uniformly distributed across the following four domains: Attitudinal, POlitical, TEChnical and Administrative (APOTECA domains). However, in terms of level (pharmacist, healthcare team, patient, institution, and national organization), the "pharmacist" group had the highest concentration of factors. "Clinical skills and knowledge" was the most frequently cited implementation factor, followed by "time to implement CPS."

CONCLUSION

Our findings showed the multifactorial nature of CPS implementation process. We suggest that factors from all four APOTECA domains need to be fully considered and strategies need to be addressed for all five groups of interest to successfully implement CPS in hospitals. Future studies on the influence of implementation stages, interrelationships of implementing factors, and strategies to overcome barriers could accelerate the successful adoption of these services.

Ready or not, here it comes: Direct-to-consumer pharmacogenomic testing and its implications for community pharmacists

OBJECTIVE

To explore the implications of direct-to-consumer pharmacogenomic testing for community pharmacy practice.

SUMMARY

In October 2018, the U.S. Food and Drug Administration provided approval for direct-to-consumer genetic testing company, 23andMe (Mountain View, CA), to return select pharmacogenomic test results to their customers. Given the community pharmacist's high accessibility to the public and in-depth knowledge of pharmacology, and the availability of direct-to-consumer genetic testing kits at pharmacies, it is likely that patients will present their pharmacogenomic test results to their pharmacists and expect them to incorporate those results into their care. It is important, therefore, that community pharmacists are aware of the clinical implications of these results, know where to turn for evidence-based clinical pharmacogenomics information, and be mindful of the need for confirmatory testing before changing therapy.

CONCLUSION

Community pharmacists are at the frontlines of health care, and as such will be at the frontlines of direct-to-consumer pharmacogenomic testing. In the near future, it is likely that community pharmacists will need to counsel patients on the interpretation and appropriate use of direct-to-consumer pharmacogenomic test results.

Pharmacogenomics courses in pharmacy school curricula

Aim: The appropriate use and integration of pharmacogenetic (PGx) testing will pivot on provider preparation and training. Pharmacists have been recognized as one of the key providers in the delivery of PGx testing and as such, professional organizations have recommended inclusion of PGx content in pharmacy curricula. Methods: We reviewed the curriculum of 132 US pharmacy schools for information about PGx courses. Results: A total of 70 core curriculum courses were identified. 55 (42%) pharmacy schools included at least one PGx course as part of the core curriculum, and ten (8%) schools that offered a PGx course elective. Conclusion: While many pharmacy schools have responded to the accreditation standards to include PGx, less than half of the schools have developed a standalone course.

Precision medicine: a call for increased pharmacogenomic education

Precision medicine is an emerging model of care where providers consider patients' genetic profiles, lifestyles and environments to offer more precise therapy. The potential of precision medicine is boundless as interdisciplinary teams utilize genetic technologies to improve patient outcomes. The integration of precision medicine into healthcare faces many barriers, including a lack of standardization and reimbursement concerns. This article argues that increased pharmacogenetics education and system-wide implementation is necessary to overcome some of these challenges. Extensive expansion of pharmacogenomics education is a step toward producing knowledgeable clinicians who are poised to apply its methodology and champion for patient-centered care.

Community pharmacists' educational needs for implementing clinical pharmacogenomic services

OBJECTIVES

Pharmacist leadership and knowledge of pharmacogenomics is critical to the acceleration and enhancement of clinical pharmacogenomic services. This study aims for a qualitative description of community pharmacists' pharmacogenomic educational needs when implementing clinical pharmacogenomic services at community pharmacies.

METHODS

Pharmacists practicing at Rite Aid Pharmacy locations in the Greater Pittsburgh Area were recruited to participate in this qualitative analysis. Pharmacists from pharmacy locations offering pharmacogenomic testing and robust patient care services were eligible to participate in a semistructured, audio-recorded interview. The semistructured interview covered 4 domains crafted by the investigative team: (1) previous knowledge of pharmacogenomics; (2) implementation resources; (3) workflow adaptation; and (4) learning preferences. Interviews were transcribed verbatim and independently coded by 2 researchers. A thematic analysis by the investigative team followed. Supporting quotes were selected to illustrate each theme.

RESULTS

Eleven pharmacists from 9 unique pharmacy locations participated in this study. The average length of practice as a community pharmacist was 12 years (range, 1.5-31 years). Pharmacist's pharmacogenomic educational needs were categorized into 5 key themes: (1) enriched pharmacogenomic education and training; (2) active learning to build confidence in using pharmacogenomic data in practice; (3) robust and reputable clinical resources to effectively implement pharmacogenomic services; (4) team-based approach throughout implementation; (5) readily accessible network of pharmacogenomic experts.

CONCLUSION

This study describes the educational needs and preferences of community pharmacists for the successful provision of clinical pharmacogenomic services in community pharmacies. Pharmacists recognized their needs for enriched knowledge and instruction, practice applying pharmacogenomic principles with team-based approaches, robust clinical resources, and access to pharmacogenomic experts. This deeper understanding of pharmacist needs for pharmacogenomic education could help to accelerate and enhance the clinical implementation of pharmacogenomic services led by community pharmacists.

Community pharmacists and their role in pharmacogenomics testing: an Australian perspective drawing on international evidence

Patients obtaining a prescription from a pharmacy expect that the drug will be effective and have minimal side-effects. Unfortunately, drugs exhibit the desired effect in ~25-60% of people prescribed any medication. Adverse effects occur at a rate of 10% in patients taking a medication, and this rate increases during and after hospitalisation, with the transition of care back to the ambulatory setting posing a particular risk. Pharmacogenomics testing has been shown to optimise pharmacotherapy by increasing medication effectiveness and reducing drug-related toxicity, thus curtailing overall healthcare costs. Evidence from international studies have shown that community pharmacists would be able to offer this highly relevant professional service to their clients, given suitable training. This specific training complements pharmacists' existing skills and expertise by educating them in an emerging scientific area of pharmacogenomics. However, in an increasingly tight financial climate, the provision of pharmacogenomics testing by Australian community pharmacists will only be viable with an appropriate reimbursement through the Medicare Benefits Schedule, currently accessible by other allied health practitioners but not by pharmacists.

Perceived barriers to the implementation of clinical pharmacy services in a metropolis in Northeast Brazil

BACKGROUND

CLinical pharmacy services (CPS) are professional services provided by pharmacists, who use their skills and knowledge to take an active role in patient health. These services have expanded in health systems around the world. However, it is important to have a comprehensive understanding of factors that may hinder the implementation of CPS in health systems.

OBJECTIVE

To identify pharmacists' and managers' perceptions of barriers regarding the implementation of CPS in some public health units in a metropolis in Northeast Brazil.

METHODS

This is a qualitative study based on focus groups and semi-structured, face-to-face, in-depth interviews. Participants were health-system pharmacists and managers, selected based on their direct participation in the implementation process. Focus groups were carried out with the pharmacists, and interviews were carried out with managers. The audio and videos were transcribed verbatim in full, and were independently analyzed using content analysis. This study was approved by the Brazilian Committee of Ethics in Research and all participants signed informed consent forms.

FINDINGS

There were two focus groups and five interviews. The discussions generated 240 minutes of recordings. The health-system pharmacists and managers expressed barriers were allocated into five categories to facilitate a comprehensive understanding of the implementation of CPS; these barriers were related to: the local healthcare networks, the healthcare team, the pharmacists, the implementation process, and the patients.

CONCLUSIONS

This study revealed the perceptions of barriers associated with the participants involved in the implementation of CPS in some public health units in a metropolis in Northeast Brazil. The barriers reflect the challenges to be overcome in the CPS implementation process in the health systems.

Pharmacist-Provided Pharmacogenetic Point-of-Care Testing Consultation Service: A Time and Motion Study

Background: With recent advances in pharmacogenomics (PGx) comes the potential to customize medication use based on genetic data. Support for PGx has found practical limitations in terms of workflow and turnaround time of a test. However, with the expansion of point-of-care testing (POCT) in pharmacy practice models comes opportunity for PGx testing in the pharmacy setting. Objective: The purpose of this study is to quantify the amount of time spent during each step of a PGx POCT encounter in a community pharmacy setting. Methods: A time and motion study was conducted using a mock community pharmacy space for a simulated PGx-focused encounter to manage antiplatelet therapy following hospital discharge. PGx POCT was conducted using the Spartan RX instrument. Simulated patient encounters were divided into 7 categories. Time spent in each step, as well as total time spent, was tracked. Results: A total of 54 simulated PGx POCT encounters took place with an average time of 9.49 minutes (SD ± 1.38 minutes). Instrument run time adds 60 minutes to the total time required to obtain a result. Duties that could be performed by an appropriately trained pharmacy technician totaled 6.86 minutes. Conclusions: PGx POCT would require 9.49 minutes of pharmacy staff hands-on time for the encounter, which could be reduced to 2.64 minutes of pharmacist time with appropriate pharmacy technician involvement. Time requirements for PGx POCT are similar to that of community pharmacy-based immunizations. Future studies could explore how practice could change if PGx testing were routinely performed in the pharmacy.

Implementation of a pharmacist-led pharmacogenomics service for the Program of All-Inclusive Care for the Elderly (PHARM-GENOME-PACE)

OBJECTIVES

To determine the feasibility of implementing a pharmacist-led pharmacogenomics (PGx) service for the Program of All-Inclusive Care for the Elderly (PACE).

SETTING

A national centralized pharmacy providing PGx services to community-based PACE centers.

PRACTICE DESCRIPTION

Individuals 55 years of age and older enrolled in PACE who underwent PGx testing as part of their medical care (n = 296).

PRACTICE INNOVATION

Pharmacist-led PGx testing, interpreting, and consulting.

EVALUATION

Implementation processes and roles were ascertained by reviewing policies and procedures for the PGx service and documented observations made by pharmacists providing the service. Genetic variants and drug-gene interactions (DGIs) were determined by interpretations of PGx test results. Types of recommendations provided by pharmacists were ascertained from PGx consultations. Prescribers' acceptance of recommendations were ascertained by documented responses or drug changes made after PGx consultations.

RESULTS

Challenges to implementation included lack of systems interoperability, limited access to medical electronic health records, determining prescribers' responses, and knowledge and competency gaps in PGx. Pharmacist roles most essential to overcoming challenges were interpreting and applying PGx data, determining how to disseminate those data to prescribers, advocating for appropriate PGx testing, and educating about the application of test results to clinical practice. Participants frequently used drugs posing DGI risks, with the majority (73.6%) reporting more than 1 interaction. The overwhelming majority (89.0%) of pharmacists' recommendations to mitigate risks were accepted by referring prescribers.

CONCLUSION

Implementing a pharmacist-led PGx service for PACE is feasible. Implementation of this service highlights the leadership role of pharmacists in moving PGx from research to practice.

Implementation of a multidisciplinary pharmacogenomics clinic in a community health system

PURPOSE

The development and implementation of a multidisciplinary pharmacogenomics clinic within the framework of an established community-based medical genetics program are described.

SUMMARY

Pharmacogenomics is an important component of precision medicine that holds considerable promise for pharmacotherapy optimization. As part of the development of a health system-wide integrated pharmacogenomics program, in early 2015 Northshore University Health-System established a pharmacogenomics clinic run by a multidisciplinary team including a medical geneticist, a pharmacist, a nurse practitioner, and genetic counselors. The team identified five key program elements: (1) a billable-service provider, (2) a process for documentation of relevant medication and family histories, (3) personnel with the knowledge required to interpret pharmacogenomic results, (4) personnel to discuss risks, benefits, and limitations of pharmacogenomic testing, and (5) a mechanism for reporting results. The most important program component is expert interpretation of genetic test results to provide clinically useful information; pharmacists are well positioned to provide that expertise. At the Northshore University HealthSystem pharmacogenomics clinic, patient encounters typically entail two one-hour visits and follow a standardized workflow. At the first visit, pharmacogenomics-focused medication and family histories are obtained, risks and benefits of genetic testing are explained, and a test sample is collected; at the second visit, test results are provided along with evidence-based pharmacotherapy recommendations.

CONCLUSION

A multidisciplinary clinic providing genotyping and related services can facilitate the integration of pharmacogenomics into clinical care and meet the needs of early adopters of precision medicine.

The Innovative Canadian Pharmacogenomic Screening Initiative in Community Pharmacy (ICANPIC) study

OBJECTIVES

The safety and efficacy of medications can vary significantly between patients as a result of genetic variability. As genomic screening technologies become more widely available, pharmacists are ideally suited to use such tools to optimize medication therapy management. The objective of this study was to evaluate the feasibility of implementing personalized medication services into community pharmacy practice and to assess the number of drug therapy problems identified as a result of pharmacogenomic screening.

SETTING

The study was conducted in 2 busy urban community pharmacies, operating under the brand Shoppers Drug Mart, in Toronto, Ontario.

PRACTICE INNOVATION

Pharmacists offered pharmacogenomic screening as part of their professional services program. Eligible patients received a buccal swab followed by DNA analysis with the use of Pillcheck. Pillcheck is a genotyping assay that translates genomic data and generates a personalized evidence-based report that provides insight into patients' inherited drug metabolic profile. After receiving the report, pharmacists invited patients back to the clinic for interpretation of the results. Clinically significant drug therapy problems were identified and recommendations for medication optimization forwarded to the primary care physician.

RESULTS

One hundred patients were enrolled in the study. Average age was 56.7 years, and patients were taking a mean of 4.9 chronic medications. Pharmacists cited the most common reasons for testing as ineffective therapy (43.0%), to address an adverse reaction (32.6%), and to guide initiation of therapy (10.4%). An average of 1.3 drug therapy problems directly related to pharmacogenomic testing were identified per patient. Pharmacist recommendations included change in therapy (60.3%), dose adjustment (13.2%), discontinuation of a drug (4.4%), and increased monitoring (22.1%).

CONCLUSION

These results highlight the readiness of community pharmacists to adopt pharmacogenomic screening into practice and their ability to leverage this novel technology to positively affect medication therapy management. Community pharmacists are ideally suited to both offer personalized medication services and interpret genomic results.

Assessing feasibility of delivering pharmacogenetic testing in a community pharmacy setting

AIM

To describe the rationale and design of a study evaluating the delivery of pharmacogenetic (PGx) testing in community pharmacies. Study rationale: Pharmacists have expressed interest in offering PGx testing; however, their lack of knowledge and experience, patients' acceptance and feasibility are unknown in this setting.

STUDY DESIGN

Through a cluster randomized trial, we will assess pharmacist and patient experiences with delivery of PGx testing as a standalone service or integrated into medication therapy management services. Anticipated results: We anticipate that PGx testing can be delivered in a community pharmacy setting and accepted and valued by patients.

CONCLUSION

This study is expected to provide valuable evidence about the real-world feasibility and acceptance of a community pharmacist-delivered approach of PGx testing.

Pharmacogenomics testing in a community pharmacy: patient perceptions and willingness-to-pay

AIM

To determine patient knowledge, interest and willingness-to-pay for pharmacogenomics testing in a community pharmacy.

PATIENTS & METHODS

The link to a cross-sectional, anonymous online survey was distributed to a convenience sample of patients. The contingent valuation method was used to assess willingness-to-pay.

RESULTS

Twenty seven surveys were completed. Eighty one percent of patients were interested in the service, but patients felt that they would be more likely to use the service if insurance covered the cost.

CONCLUSION

Patients indicated interest in a pharmacogenomics test, but varying levels of willingness-to-pay. Patients may not be able to connect the benefits of testing to their health, justifying further patient education in order to increase the viability of pharmacogenomics testing as a pharmacy service.

The role of hospital pharmacists in the adoption and use of pharmacogenomics and precision medicine

Aim: Our aim was to assess the knowledge and attitudes of US hospital pharmacists about the implementation of clinical pharmacogenomics, and examine liability risks of adopting pharmacogenomics by pharmacists. Methods: We surveyed hospital pharmacists. Linear regression models of predictor variables for pharmacist adoption and use of pharmacogenomics were analyzed. Results: The survey was administered to 660 hospital pharmacists (23% response rate; n = 149). The majority of respondents (72%) favor implementing pharmacogenomics into pharmacy practice. However, only 25% are confident in their abilities to interpret pharmacogenomic test results. Conclusion: Pharmacists lack confidence in their abilities to interpret and use pharmacogenomic information in clinical care. These results raise potential liability risks that are pertinent to pharmacists.

Community pharmacists' experience with pharmacogenetic testing

OBJECTIVE

Appendix 1 Statements of knowledge of correct medication use Appendix 2 Statements of self-efficacy of correct medication use Appendix 3 Statements of skills of correct medication use To characterize the experiences and feasibility of offering pharmacogenetic (PGx) testing in a community pharmacy setting.

DESIGN

Pharmacists were invited to complete a survey about PGx testing for each patient who was offered testing. If the patient consented, pharmacists were also asked to complete a follow-up survey about the process of returning PGx testing results to patients and follow-up with the prescribing provider.

SETTING

Community pharmacies in North Carolina from August through November 2014.

PARTICIPANTS

Pharmacists at five community pharmacies.

MAIN OUTCOME MEASURES

Patient consent for testing, time to introduce PGx testing initially and communicate results, interpretation of test results, and recommended medication changes.

RESULTS

Of the 69 patients offered testing, 56 (81%) consented. Pre-test counseling typically lasted 1-5 minutes (81%), and most patients (55%) did not have any questions about the testing. Most pharmacists reported test results to patients by phone (84%), with discussions taking less than 1 minute (48%) or 1-5 minutes (52%). Most pharmacists believed the patients understood their results either very well (54%) or somewhat well (41%). Pharmacists correctly interpreted 47 of the 53 test results (89%). All of the incorrect interpretations were for patients with test results indicating a dosing or drug change (6/19; 32%). Pharmacists reported contacting the ordering physician for four patients to discuss results indicating a dosage or drug change.

CONCLUSION

The provision of PGx services in a community pharmacy setting appears feasible, requiring little additional time from the pharmacist, and many patients seem interested in PGx testing. Additional training may be necessary to improve test result interpretation, as well as for communication with both patients and ordering physicians.

Evaluation of a pharmacogenetic educational toolkit for community pharmacists

AIM

Over the past several decades, the roles and services of community pharmacists have expanded beyond traditional medical dispensation and compounding, and include health services such as vaccinations, and clinical testing and screening. Incorporating pharmacogenetic (PGx) testing into the menu of pharmacy services is logical and feasible; however, few pharmacists have experience with PGx testing, and few educational resources about PGx are available to support the uptake of PGx testing in community pharmacies.

METHODS

We developed a toolkit of four resources to assist pharmacists to provide PGx testing. We conducted a survey of pharmacists in North Carolina to evaluate each component of the toolkit and the toolkit as a whole.

RESULTS

A total of 380 respondents completed the evaluation of one or more toolkit components (344 evaluated all four components and the overall toolkit). Most respondents (84%) have never ordered or used PGx test results. Though the usability of the toolkit overall was below average (65.1 on a range of 0-100), individual components were perceived as useful and more than 75% of pharmacists reported that they would use the toolkit components when offering testing, with the result summary sheet receiving the highest score (4.01 out of 5). Open-text comments highlighted the need for more patient-friendly language and formatting.

CONCLUSION

The majority of pharmacist respondents scored the components of the toolkit favorably. The next steps will be to revise and assess use of the toolkit in community pharmacy settings.

Academic and professional pharmacy education: a pharmacogenomics certificate training program

Aim: The aim of this study was to evaluate a pharmacogenomics certificate training program relative to pharmacist competencies in basic genetic concepts, genetics and disease, pharmacogenetics/pharmacogenomics and ethical, legal and social implication. Methods: Participants, including pharmacists, pharmacy students and pharmacy educators completed a survey related to to the competency statements. Following the pre-program survey, participants completed a 6-week home self-study with subject matter including basic science (three chapters) and clinical application of pharmacogenomics (eight chapters). The participants completed a quiz for each of the self-study chapters. Following the self-study, participants completed a day-long, 7-h live program which included a review of the competency statements and counseling sessions with seven different simulated patients (primarily pharmacy students). Participants then completed a post-program survey which included the same items as the pre-program survey. Results: Specifically, for the pharmacist participants, the average score of the self-study quizzes was 91%. For the pharmacists specifically, there was a statistically significant increase in self-assessed perception of competence related to pharmacogenomics. Additionally, it was observed that recommendations related to specific drug–gene interactions for the simulated patients were addressed correctly 95% of the time across all participant–patient encounters. Conclusion: Self-study and a live, interactive component in the certificate training program led to increased self-understanding of defined pharmacogenomics competencies. Additionally, pharmacy students, in the role of simulated patients gained knowledge during the live component of the program. This type of program, especially if made available through electronic-based platforms can serve to educate pharmacists and increase the uptake of pharmacogenomics in various healthcare settings.

Implementation of a pharmacogenetic management service for postmyocardial infarction care in a community pharmacy

AIM

The purpose of this study was to pilot a multisite, proof-of-concept model where community pharmacists could engage patients and physicians to provide pharmacogenetic (PGt) testing and clinical decision support.

PATIENTS & METHODS

Patients with history of acute myocardial infarction and percutaneous coronary intervention with no prior history of CYP2C19 testing.

RESULTS

Four community pharmacies provided pharmacogenetic testing and medication therapy management services to 30 patients, resulting in eight recommendations for antiplatelet therapy adjustment.

CONCLUSION

Pharmacists involved in the study were able to facilitate antiplatelet therapy adjustments based on PGt data regardless of baseline antiplatelet drug selection. Whereas prior literature largely revolved around PGt management in the inpatient setting, this project supports the involvement of the community pharmacist in making PGt-based recommendations.
