Abstract
OBJECTIVE This study aims to understand patient and healthcare provider perspectives on the integration and application of pharmacogenetics (PGx) testing in routine clinical practice. METHODS Two anonymous online surveys were distributed globally for healthcare providers and patients respectively on the Qualtrics platform (version 3.24). The surveys were distributed through social platforms, email, and posters with QR codes from 27 October 2023 to 7 March 2024. The surveys evaluated participant familiarity with PGx, previous experience with PGx testing, perceived implementation challenges, and opinions on point-of-care (PoC) PGx testing devices. RESULTS This study collected 78 responses from healthcare providers and 98 responses from patients. The results revealed that 64% of healthcare providers had some level of familiarity with PGx, however, PGx testing in clinical practice was low. The primary challenges identified by healthcare providers included limited access to testing and lack of knowledge on PGx test interpretation. In contrast, 52% of patient respondents were aware of PGx testing, with a significant association between awareness and positive opinions toward PGx. Both healthcare providers and patients recognized the value of PoC PGx testing devices, with 98% of healthcare providers and 71% of patients believing PoC devices would improve the accessibility and implementation of PGx testing. Comparative analysis revealed a statistically significant difference in PGx awareness between healthcare providers and patients, with providers being more informed. CONCLUSION Improved PGx awareness, training, clinical guidelines, and PoC PGx testing devices may help promote the implementation of PGx-guided treatments in routine clinical practice.

Abstract
Although French genomic medicine is reaching a turning point in its history and the implementation of genome sequencing in routine is being implemented as part of the France Genomic Medicine 2025 Plan (FGMP), many questions about secondary data management remain to be addressed. In particular, the use of pharmacogenetic (PGx) information that can be extracted from genome data is a concern. We sought to analyze the opinion of French health professionals on their desire to have access to this information. For this purpose, we created a 22-item questionnaire on the experiences, attitudes, expectations, and knowledge of French physicians and pharmacists about PGx. We collected the responses in different groups and determined a knowledge score with the last 3 questions of the questionnaire. Then, we built a prediction model for this score and determined which factors may influence it. Half of the responders were physicians (158/311) and the other half were pharmacists (153/311), and the majority of them worked in a hospital (265/311). Almost two third (62.7%, 195/311) of the responders thought that pharmacogenetic data should be communicated with genomic results for the primary indication within the framework of FGMP, and 89.1% (277/311) of them that PGx tests could be an interesting tool to optimize patients' drug therapy in the future. Only 11.2% (35/311) of the responders reached the maximum knowledge score, while 25.4% (76/311) had already prescribed or recommended a PGx test. This study identified a need for training for French physicians and pharmacists in PGx, particularly given the interest of health professionals in it.

Health Sci Rep 2024; 7:e1844. [PMID: 38274140 PMCID: PMC10809028 DOI: 10.1002/hsr2.1844] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Revised: 12/09/2023] [Accepted: 01/08/2024] [Indexed: 01/27/2024] Open
Abstract
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.

Abstract
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.

Abstract
Aims: To study the readiness of Russian physicians with experience and younger physicians undergoing clinical residency and postgraduate education to apply pharmacogenetic testing in their clinical practice. Materials & methods: The sociological study involved physicians (n = 378) living in different regions of the Russian Federation, as well as residents and graduate students (n = 185) of the Russian Medical Academy of Continuing Professional Medical Education. The survey consisted of 35 questions, and 23 were created on the online platform of professional surveys, Testograf.ru. Results: Every second respondent was willing to use pharmacogenetic testing in clinical practice to predict the efficacy and safety of medications in patients with cardiovascular disease (p = 0.06). Factors impeding the clinical implementation of pharmacogenetic testing in Russia were identified: physicians' ignorance of pharmacogenetics (p = 0.015), a lack of pharmacogenetic testing in clinical guidelines and treatment standards (p = 0.175) and a lack of economic justification for using pharmacogenetic testing (p = 0.320). Conclusion: Russian physicians have a positive attitude toward pharmacogenetic testing. However, the level of test implementation remains low.

Abstract
(1) Background: Uptake of pharmacogenomic testing in routine clinical practices is currently slow in China. Pharmacists might play an important role in leveraging care through applying pharmacogenomics, therefore, it is important to better understand clinical pharmacists’ knowledge of and attitudes toward pharmacogenomic testing, which has not been well-studied. (2) Methods: A self-administered survey was developed based on previous knowledge of pharmacogenomic testing and its uptake in China. Participants were recruited through the Committee of Pharmaceutical Affairs Management under the Chinese Hospital Association. (3) Results: A total of 1005 clinical pharmacists completed the questionnaire, among whom 996 (99.10%) had heard of pharmacogenomic testing before participation. More than half of respondents (60.0%, n = 597) rated their knowledge of pharmacogenomic testing as “average”, while 25% rated it “good” or “excellent”. “Guidelines, consensus and treatment paths for disease diagnosis and treatment” (78.7%) were the most preferred sources of information about pharmacogenomic testing. Most respondents (77.0%) believed that pharmacogenomics could “help to improve efficacy and reduce the incidence of adverse reactions”. Our participants also believed that patients would benefit most from pharmacogenomic testing through better prediction of individual drug responses and thus informed treatment decisions. The top challenge for the uptake of pharmacogenomic testing was its high cost or lack of insurance coverage (76.7%). (4) Conclusions: Most Chinese clinical pharmacists who participated in our study had a positive attitude toward pharmacogenomic testing, while the knowledge of pharmacogenomic testing was generally self-assessed as average.

Abstract
Background: Pharmacogenomics (PGx) testing is increasingly used in clinical practice to optimize drug therapies. This study aims to understand the involvement of clinical pharmacists in PGx testing at tertiary hospitals in China and their self-assessed capacity to deliver such services. Methods: We developed a questionnaire exploring clinical pharmacists’ involvement and self-assessed level of capacity of performing PGx tests. A random sample was obtained from the Pharmaceutical Affairs Management Professional Committee of the Chinese Hospital Association. Results: A total of 1005 clinical pharmacists completed the survey. Of these, 996 (99.1%) had heard of PGx tests and 588 (59.0%) had been involved in PGx testing and related services. Some clinical pharmacists (28.9%) provided PGx services at the rate of “1−5 cases/year” while 21.9% of clinical pharmacists provided PGx services at the rate of “>30 cases/year”. Clinical pharmacists most frequently provided PGx testing for cardiovascular diseases. “Consult relevant guidelines/literature” (90.1%) was the most frequently used method to familiarize oneself with PGx testing. About 60% of the pharmacists considered themselves to have poor or fair capacity to provide PGx testing and related services. Conclusions: More than half of the pharmacists had been involved in PGx testing and related services. However, pharmacists generally had little confidence in their knowledge level of and capacity to provide PGx-related services.

Examining key factors impact on health science students' intentions to adopt genetic and pharmacogenomics testing: a comparative path analysis in two different healthcare settings.

Abstract
BACKGROUND There is an increasing interest worldwide in investigating healthcare stakeholders' perceptions and intentions to adopt pharmacogenomics (PGx) into clinical practice. However, the existing inquiries based on well-established theories and models that interpret their intentions to implement PGx are scarce. This study is the first that examines the impact of selected factors on health science students' intention to adopt genetic testing applications using the technology acceptance model while it compares two different cultural groups: Greeks (Europe; Christian) and Malays (Asia; Muslim). RESULTS Malay students were more persuaded about benefits of genomics for drug management compared to their Greek counterparts. However, participants from both countries appear to be particularly convinced about the benefits of genomics on disease management. Moreover, students from both countries considered the potential misuse of genetic information by corporate or government bodies as their most important concern; Greek students appeared to be considerably less worried than Malay about other probable hazards such as the deficient protection of privacy and confidentiality, which could be attributed to their religious background. Participants from both samples expressed very positive attitudes towards genetic research and testing and their favourable intentions to adopt genetic testing for personal use. Exploratory factors analysis and path analysis yielded quite similar results for both samples. Path analysis revealed that the factors of attitudes, concerns, drug management benefits and disease management benefits significantly influenced students' intentions to adopt genetic testing for personal use, with attitudes being the most inspirational factor with rather high impact, while training did not seem to affect participant's intentions. The squared multiple correlation of both models was quite satisfactory reaching to 0.55 for the Malaysian sample. CONCLUSION Similarities in the results of the two groups along with the relevant validity and reliability tests indicate that the proposed model is a good fit for future studies to interpret stakeholders' intentions to adopt genetic testing. Therefore, it can provide a promising and reliable basis for future model development to explain the relationships between intentions to adopt genetic testing and its predictors.

OBJECTIVES To assess the perception of pharmacists and physicians towards pharmacogenetic testing. METHODS A self-administered questionnaire was developed, validated, tested for reliability and disseminated to pharmacists and physicians in Malta. KEY FINDINGS The study population consisted of 292 participants; 61% pharmacists (64% female, 38% practicing >10 years) and 39% physicians (50% female, 54% practicing >10 years). Pharmacists and physicians felt they lack sufficient competence in the area (95.0% and 97.4%, respectively; P > 0.05) and agreed that further training is required (92.7% and 91.2%, respectively; P > 0.05). CONCLUSIONS The need for further training was identified by the participants to support competency development and sustain confidence on the topic, hence facilitating the clinical implementation of pharmacogenetic testing.

Pharmacogenomic testing: perception of clinical utility, enablers and barriers to adoption in Australian hospitals. Intern Med J 2022; 52:1135-1143. [PMID: 35191159 PMCID: PMC9541847 DOI: 10.1111/imj.15719] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 02/01/2022] [Accepted: 02/02/2022] [Indexed: 11/29/2022]
Abstract
Background Despite healthcare professionals (HCP) endorsing the clinical utility of pharmacogenomics testing, use in clinical practice is limited. Aims To assess HCP' perceptions of pharmacogenomic testing and identify barriers to implementation. Methods HCP involved in prescribing decisions at three hospitals in Sydney, Australia, were invited to participate. The online survey assessed perceptions of pharmacogenomic testing, including: (i) demographic and practice variables; (ii) use, knowledge and confidence; (iii) perceived benefits; (iv) barriers to implementation; and (v) operational and/or system changes and personnel required to implement on site. Results HCP were predominantly medical practitioners (75/107) and pharmacists (25/107). HCP perceived pharmacogenomic testing was beneficial to identify reasons for drug intolerance (85/95) and risk of side‐effects (86/95). Although testing was considered relevant to their practice (79/100), few HCP (23/100) reported past or intended future use (26/100). Few HCP reported confidence in their ability to identify indications for pharmacogenomic testing (14/107), order tests (19/106) and communicate results with patients (16/107). Lack of clinical practice guidelines (62/79) and knowledge (54/77) were identified as major barriers to implementation of pharmacogenomics. Comprehensive reimbursement for testing and clinical practice guidelines, alongside models‐of‐care involving multidisciplinary teams and local clinical champions were suggested as strategies to facilitate implementation of pharmacogenomic testing into practice. Conclusions Pharmacogenomic testing was considered important to guide drug selection and dosing decisions. However, limited knowledge, low confidence and an absence of guidelines impede the use of pharmacogenomic testing. Establishment of local resources including multidisciplinary models‐of‐care was suggested to facilitate implementation of pharmacogenomics.

Abstract
Background Pharmacogenetics targets genetic variations that influence drug response. It is relatively a new science that has not been vastly employed in most developing countries including Syria. Therefore we aimed at evaluating the depth of knowledge in pharmacogenetics and the attitude towards it amongst Syrian pharmacists and physicians. Methods We carried out an internet-based questionnaire consisted of 26 questions, sent through specialized websites and private groups with a large number of pharmacists and physicians members. The survey was available online for a period of 1 month. Results The total number of respondents was 154, mostly female pharmacists. Our statistical analysis showed a strong positive association between profession (in favour of pharmacists) and pharmacogenetics knowledge p = 0.049; however, no correlation with experience p = 0.811 was found. A significant difference was reported between the knowledge of pharmacists and physicians p = 0.001 concerning drugs that need pharmacogenetics testing before being prescribed. The majority of respondents had no information about applying genetic tests in Syria before prescribing medications nor did they possess the knowledge regarding drugs that show differential responses in patients according to their unique genotypes. In our study, the percentage knowledge assessment score was low in general (mean ± Standard deviation, SD) (46% ± 13.9%). The majority of the respondents agreed that pharmacists should provide counselling to patients on the subject of pharmacogenetics. Respondents’ opinions varied concerning making pharmacogenetics learning a priority. Conclusion Lack of pharmacogenetics knowledge was found amongst respondents in general. Our findings raise concerns about the lack of awareness amongst physicians, which may hinder the implementation of this crucial field in Syria. We suggest an emphasis on the role of education, training, and conducting genotyping research on the Syrian population.

Abstract
BACKGROUND AND OBJECTIVES Pharmacogenomics (PGx) is the use of human genomic information to avoid toxicity and optimize efficacy of drug therapy in an individual. Hospital pharmacists are the key persons to facilitate the incorporation of PGx into clinical practice. PGx is relatively new to Thai hospital pharmacists. Therefore, this study aimed to evaluate the knowledge, attitude, and practice of Thai hospital pharmacists towards PGx implementation. MATERIALS AND METHODS We conducted a cross-sectional questionnaire-based survey among 600 hospital pharmacists in 21 hospitals across Thailand. The questionnaire consisted of 35 questions using comment boxes, Likert scales, and multiple choice answers. RESULTS The response rate was 20.5% (n = 123). Nearly half of the hospital pharmacists (46.3%) had low PGx knowledge score (<5 points), particularly for applied PGx knowledge in clinical situations. Concerns regarding PGx reimbursement, privacy issues, and discrimination were mentioned in this survey. However, most hospital pharmacists had positive attitude towards PGx service. Only 7% of hospital pharmacists had recommended or interpreted PGx tests in the past year. National PGx guidelines and government policies were considered the important factors for PGx implementation. Moreover, the most preferred learning format for PGx education was professional academic conferences. CONCLUSION Hospital pharmacists in Thailand had positive attitude towards PGx, despite limited experience and practice of PGx. PGx education to support an application of PGx knowledge in clinical situations is required. National PGx guidelines and government policies may need to be developed to address the concerns for reimbursement, privacy, and discrimination to ensure successful PGx implementation.

Abstract
To elucidate current domestic factors influencing pharmacogenomics (PGx) implementation and its future in China, we conducted a questionnaire survey on PGx applications and testing. A questionnaire-based survey was created on the popular online professional survey platform "Wenjuanxing" (www.wjx.cn) and performed via the social media platform WeChat. Among 422 participants, there were physicians (27.7%), pharmacists (31.3%), and researchers (41.0%). We found that less than 50% of physicians were aware of the importance of PGx in drug therapy, while over 50% of pharmacists and researchers recognized the importance. Only 38.5% of physicians, 40.9% of pharmacists, and 55.5% of researchers concurred that PGx analysis could lower the economic burdens for patients. However, most of the responders affirmed that PGx should be effectively implemented in clinical practices. A lack of sector standards, a lack of clinical research, and a lack of guidelines were found to be the major factors for hindering PGx clinical application. Among drugs associated with PGx assays, the most common were warfarin and clopidogrel. Although PGx research has advanced rapidly in recent years in mainland China, the clinical implementation of PGx has a long way to go.

Abstract
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.

Abstract
Community pharmacy services have evolved to include medical and pharmaceutical interventions alongside dispensing. While established pharmacogenomic (PGx) testing is available throughout the Netherlands, this is primarily based in hospital environments and for specialist medicines. The aim of this work was to describe how best to implement PGx services within community pharmacy, considering potential barriers and enablers to service delivery and how to address them. The service was implemented across a selection of community pharmacies in the Netherlands. Data were captured on test outcomes and through a pharmacist survey. Following testing, 17.8% of the clinical samples were recommended to avoid certain medication (based on their current medicines use), and 14.0% to have their dose adjusted. Pre-emptive analysis of genotyped patients showed that the majority (99.2%) had actionable variants. Pharmacists felt confident in their operational knowledge to deliver the service, but less so in applying that knowledge. Delivering the service was believed to improve relationships with other healthcare professionals. These results add to the evidence in understanding how PGx can be delivered effectively within the community pharmacy environment. Training pharmacists in how to respond to patient queries and make clinical recommendations may enhance service provision further.

Abstract
WHAT IS KNOWN AND OBJECTIVE Pharmacogenomics (PGx) testing can be effective for supporting precision medicine. The purpose of this study was to assess the knowledge, attitude and practice behaviours of pharmacists in relation to such testing through a survey. We also aimed to identify potential obstacles to implementation of PGx testing by pharmacists and the characteristics of hospital pharmacists involved. METHODS We performed a web-based survey regarding PGx in Japan. The survey contained a questionnaire related to PGx, which consisted of 30 items and was made accessible via the official Japanese Society of Pharmaceutical Health Care and Sciences (JSPHCS) website. The characteristics of hospital pharmacists associated with involvement in PGx testing were evaluated using univariate and multivariate analyses. RESULTS AND DISCUSSION One thousand three-hundred and thirteen pharmacists responded to the survey. The results revealed that the majority of respondents recognized the role that germline PGx testing can play in determining individual drug responses and that pharmacists have embraced the potential of PGx testing to improve patient care. However, only 26% of pharmacists were involved in PGx testing. We also found that most respondents (81.0%) believed that the lack of insurance coverage for PGx testing was a major barrier to its clinical implementation. Hospital pharmacists involved in PGx testing included certified pharmacists in JSPHCS and pharmacists who had studied PGx in university; however, only 12.4% of pharmacists had received specific PGx-related education. WHAT IS NEW AND CONCLUSION The findings of this survey highlight the necessity to increase the number of PGx tests covered by insurance, and the importance of effective education to inform and facilitate clinical implementation of PGx testing.

Abstract
Pharmacogenetics represents a major driver of precision medicine, promising individualized drug selection and dosing. Traditionally, pharmacogenetic profiling has been performed using targeted genotyping that focuses on common/known variants. Recently, whole-genome sequencing (WGS) is emerging as a more comprehensive short-read next-generation sequencing approach, enabling both gene diagnostics and pharmacogenetic profiling, including rare/novel variants, in a single assay. Using the example of the pharmacogene CYP2D6, we demonstrate the potential of WGS-based pharmacogenetic profiling as well as emphasize the limitations of short-read next-generation sequencing. In the near future, we envision a shift toward long-read sequencing as the predominant method for gene diagnostics and pharmacogenetic profiling, providing unprecedented data quality and improving patient care.

Abstract
One application of personalized medicine is the tailoring of medication to the individual, so that the medication will have the highest chance of success. In order to individualize medication, one must have a complete inventory of all current pharmaceutical compounds (a detailed formulary) combined with pharmacogenetic datasets, the genetic makeup of the patient, their (medical) family history and other health-related data. For healthcare professionals to make the best use of this information, it must be visualized in a way that makes the most medically relevant data accessible for their decision-making. Similarly, to enable bioinformatics analysis of these data, it must be prepared and provided through an interface for controlled computational analysis. Due to the high degree of personal information gathered for such initiatives, privacy-sensitive implementation choices and ethical standards are paramount. The Personal Genetic Locker project provides an approach to enable the use of personal genomic data in primary care. In this paper, we provide a description of the Personal Genetic Locker project and show its utility through a use case based on open standards, which is illustrated by the 4MedBox system.

Abstract
The clinical implementation of pharmacogenetic biomarkers continues to grow as new genetic variants associated with drug outcomes are discovered and validated. The number of drug labels that contain pharmacogenetic information also continues to expand. Published, peer-reviewed clinical practice guidelines have also been developed to support the implementation of pharmacogenetic tests. Incorporating pharmacogenetic information into health care benefits patients as well as clinicians by improving drug safety and reducing empiricism in drug selection. Barriers to the implementation of pharmacogenetic testing remain. This review explores current pharmacogenetic implementation initiatives with a focus on the challenges of pharmacogenetic implementation and potential opportunities to overcome these challenges.

Abstract
Over the past decade, pharmacogenetics (PGx) became an essential tool for personalized medicine although its clinical implementation is still limited. We aimed to assess the current level of knowledge, applications, and expectations of Flemish pharmacists and physicians towards PGx and determine the factors that influence healthcare professionals' knowledge of PGx, aiming to guide future implementation initiatives. A web-based cross-sectional survey was conducted from 8 March 2019 to 8 April 2019, targeting pharmacists, physicians, and trainees of both professions. Ten questions were used to assess the participants' knowledge about PGx. Multivariable linear regression was used to assess the association of profession, experience, practice setting, and prior education with the level of PGx knowledge. In total, 201 Flemish healthcare providers participated, including 100 pharmacists, 73 physicians, and 28 trainees. The majority (78%) of participants were unfamiliar with the basic principles of PGx and its application in clinical practice. The mean percentage of correct answers achieved for the knowledge assessment questions was 34%. Only 9% had counseled patients, while 8% assisted other healthcare professionals on PGx tests the past year. Participants' PGx knowledge was significantly affected by their profession, practice setting, and level of prior education independent of years of experience. These findings provide insight into factors affecting the knowledge of PGx and the current level of PGx implementation in Flemish clinical practice. This may form a basis for developing educational initiatives to enhance the clinical application of PGx in Flanders.

Abstract
INTRODUCTION Our objective was to evaluate physicians' perspectives on the clinical utility of pharmacogenetic (PGx) testing in kidney, liver, heart, and lung transplantation (KLHL-Tx). METHODS A 36-question web-based survey was developed and administered to medical and surgical directors of US KLHL-Tx centers. RESULTS There were 82 respondents (10% response rate). The majority were men (78%), non-Hispanic whites (70%), medical directors (72%), and kidney transplant physicians (35%). Although 78% of respondents reported having some PGx education, most reported lack of confidence in their PGx knowledge and ability to apply a PGx test. Participants reported mixed views about the clinical utility of PGx testing-most agreed with the efficacy of PGx testing, but not the benefits relative to the risks or standard of care. While 55% reported that testing was available at their institution, only 38% ordered a PGx test in the past year, most commonly thiopurine-S-methyltransferase. Physician-reported barriers to PGx implementation included uncertainty about the clinical value of PGx testing and patient financial burden. CONCLUSION Together, our findings suggest prospective PGx research and pilot implementation programs are needed to elucidate the clinical utility and value of PGx in KLHL-Tx. These initiatives should include educational efforts to inform the use of PGx testing.

Abstract
BACKGROUND While pharmacists are well positioned to implement pharmacogenomic testing in healthcare systems, uptake has been limited. OBJECTIVE The primary objective of this survey was to determine how post-graduate education and training influences pharmacist's knowledge and attitudes of pharmacogenomic testing. METHODS Survey questions were developed by the study team, and responses were collected electronically using REDCap™. The electronic survey was sent to all pharmacists (n=161) within a large, multi-state healthcare system by email. RESULTS A total of 75 (47%) respondents completed all aspects of the survey. The majority of respondents were female (60%), worked in acute care settings (57%), were full-time employees (80%), and worked in an urban area (85%), with many graduating in or after 2010 (43%). For post-graduate education, 36% of respondents completed a Post-Graduate Year One Residency (PGY-1), and 27% had a board certification. Those that completed a PGY-1 residency were significantly more likely to have received formal training or education on pharmacogenomics than those who had not. They also assessed their own knowledge of pharmacogenomic resources and guidelines higher than those without PGY-1 training. More recent graduates were also significantly more likely to have received formal training or education on pharmacogenomics. Additionally, pharmacists who completed a PGY-1 residency were more likely to respond favorably to pharmacogenomics being offered through pharmacy services. Pharmacists with board certification were more comfortable interpreting results of a pharmacogenomic test than those without board certification. CONCLUSIONS Pharmacists who have completed a PGY-1 residency or received board certification appear more comfortable with interpretation and implementation of pharmacogenomic testing.

Abstract
Despite overcoming many implementation barriers, pharmacogenomic (PGx) panel-testing is not routine practice in the Netherlands. Therefore, we aim to study pharmacists' perceived enablers and barriers for PGx panel-testing among pharmacists participating in a PGx implementation study. Here, pharmacists identify primary care patients, initiating one of 39 drugs with a Dutch Pharmacogenetic Working Group (DPWG) recommendation and subsequently utilizing the results of a 12 gene PGx panel test to guide dose and drug selection. Pharmacists were invited for a general survey and a semi-structured interview based on the Tailored Implementation for Chronic Diseases (TICD) framework, aiming to identify implementation enablers and barriers, if they had managed at least two patients with actionable PGx results. In total, 15 semi-structured interviews were performed before saturation point was reached. Of these, five barrier themes emerged: (1) unclear procedures, (2) undetermined reimbursement for PGx test and consult, (3) insufficient evidence of clinical utility for PGx panel-testing, (4) infrastructure inefficiencies, and (5) HCP PGx knowledge and awareness; and two enabler themes: (1) pharmacist perceived role in delivering PGx, and (2) believed clinical utility of PGx. Despite a strong belief in the beneficial effects of PGx, pharmacists' barriers remain, an these hinder implementation in primary care.

Abstract
Aim: To evaluate the current opinion, experience and educational preferences of pharmacists in Quebec concerning pharmacogenomics. Method: A web-based survey containing 25 questions was sent to all Quebec pharmacists. Results: Most pharmacists were willing to advise patients (81%) and physicians (84%) on treatment choices based on pharmacogenomic test results after proper training. Only 31% had been previously exposed to pharmacogenomic test results, and 91% were favorable to pharmacogenomics training, with e-learning through interactive video sessions (69%). The preferred training session length was between 1 and 3 h (59%). Hospital pharmacists were more often exposed to pharmacogenomic tests (p < 0.0001) and more frequently advised patients on treatment choices (p < 0.001) than community pharmacists. Conclusion: Pharmacists remain favorable toward pharmacogenomics, but its use in clinical practice stays limited. Identifying the educational preferences of pharmacists may help in the development of educational programs to help them integrate pharmacogenomics in their clinical practice.

Abstract
Aim: The pharmacists are identified as one of the best positioned health professionals to lead intercollaborative efforts in tailoring medication based on pharmacogenetic information. As pharmacotherapy specialists, they can take on a prominent role in ordering and interpreting pharmacogenetic test results and then guiding optimal drug selection and dose based on those results. Participants & methods: To assess the readiness of pharmacists and trainees in the province of Quebec to assume this role, we surveyed their knowledge in (pharmaco)genetics, their confidence in their ability to use pharmacogenetics and their attitude toward the integration of this tool in clinical practice. Results: A total of 99 pharmacists (community: 67.7%, hospital: 24.2% and other: 8.1%) and 36 students volunteered in a self-administered online survey. About 50% of the questions on the participants’ knowledge are answered correctly, with a stepwise increase of right answers with hours of education in (pharmaco)genetics (51.2, 63.8 and 76.7% for <5, 5–25 and >25 h respectively; p < 0.0001). While the majority of participants believe that pharmacogenetics will gain more room in their future practice (80.7%), the overall rate of confidence in their ability to use pharmacogenetics information is low (22%) and 90.3% desire more training. Conclusion: The limited experience of pharmacists in pharmacogenetics appears to be a barrier for its integration in clinical practice.

Abstract
The field of pharmacogenomics (PGx) is gradually shifting from the reactive testing of single genes toward the proactive testing of multiple genes to improve treatment outcomes, reduce adverse events, and decrease the burden of unnecessary costs for healthcare systems. Despite the progress in the field of pharmacogenomics, its implementation into routine care has been slow due to several barriers. However, in recent years, the number of studies on the implementation of PGx has increased, all providing a wealth of knowledge on different solutions for overcoming the obstacles that have been emphasized over the past years. This review focuses on some of the challenges faced by these initiatives, the solutions and different approaches for testing that they suggest, and the evidence that they provide regarding the benefits of preemptive PGx testing.

Abstract
Despite the nationwide availability of pharmacogenomic (PGx) guidelines in electronic medication surveillance systems in The Netherlands, PGx guided prescribing is still uncommon in primary care. We set out to investigate the adoption of pharmacist initiated PGx testing in primary care. Community pharmacists were offered a free PGx test covering 40 variants in 8 genes to test patients receiving an incident prescription (IRx) of a selection of 10 drugs. Results of the PGx test along with predicted phenotypes and a therapeutic recommendation based on the Dutch Pharmacogenetics Working Group (DPWG) guidelines were transferred to the pharmacist and physician. Adoption was defined as the percentage of eligible patients that received genotyping. From November 2014-July 2016, 200 patients were included with an adoption of 18.0%. Of the included patients 57.5% received an IRx for atorvastatin, 14.5% started with simvastatin and 28.0% received an IRx for amitriptyline, (es)citalopram, nortriptyline, or venlafaxine. 90% of the patients carried at least one actionable PGx test result in the selected PGx-panel. In 31.0% of the incident prescriptions a combination between a drug with a known gene-drug interaction and an actionable genotype was present and a therapeutic recommendation was provided. The provided recommendations were accepted by the clinicians in 88.7% of the patients. Pharmacist initiated implementation of PGx in primary care is feasible, and the frequency of actionable gene-drug interactions for the selected drugs is high.

Abstract
BACKGROUND Pharmacogenetics (PGx) is currently implemented in hospitals to optimize therapy with high-risk drugs. However, many drugs with dosing recommendations from the Dutch Pharmacogenetics Working Group and the Clinical Pharmacogenetics Implementation Consortium are used in primary care. Actionable phenotypes for the genes covered in these guidelines are common with estimates ranging from 85 to 95% of the population carrying at least one actionable phenotype. The goal of this study was to estimate the clinical impact of implementation of an upfront panel-based pharmacogenetic screening for eight genes related to drugs used in primary care for 2016. METHODS For this study, dispensing data concerning first prescription for the period January 1-December 31, 2016, were combined with frequency data obtained in the "Implementation of Pharmacogenetics into Primary Care Project" (IP3) study to estimate the occurrence of actionable gene-drug pairs in daily practice in community pharmacies. RESULTS In 23.6% of all new prescriptions of 45 drugs (n = 856,002 new prescriptions/year), an actionable gene-drug interaction (GDI) was present according to the guidelines of the Dutch Pharmacogenetics Working Group. More importantly, these GDIs would result in a dose adjustment or switch to another drug in 5.4% of all new prescriptions. CONCLUSIONS Consequently, with an anticipated near future where healthcare professionals will be regularly confronted with PGx test results, adjusting pharmacotherapy based on this information will become a routine task in healthcare.

Abstract
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.

Abstract
Surveys among pharmacists and physicians show that these healthcare professionals have successfully adopted the concept of pharmacogenomics (PGx).1-3 In addition, patients are willing to consent to participate in PGx implementation studies.4 However, the surveys also show that healthcare professionals do not frequently order or recommend a PGx test.1,2 Among others, a frequently perceived hurdle for clinical uptake of PGx is the availability of guidelines translating PGx test results into clinical actions for individual patients.5,6.

Abstract
Aim: To benchmark knowledge and attitude of pharmacy students toward pharmacogenetics (PGx) and PGx testing and compare the results with practicing colleagues. Methods: All pharmacy students in The Netherlands were invited to participate in a web-based survey consisting of 28 questions. Out of the 824 invited students, 148 individuals (18.0%) completed the questionnaire. All responders believed in the concept of PGx and had high expectations toward PGx. The majority (96.6%) had received some form of education on PGx, but only 12.8% felt adequately informed. Results: When compared with practicing pharmacists, differences were observed in the use of information and feeling qualified to recommend PGx testing. Conclusion: More education on PGx is required in the curriculum to fill the perceived knowledge gap among future pharmacists.

Abstract
Currently, germline pharmacogenomics (PGx) is successfully implemented within certain specialties in clinical care. With the integration of PGx in pharmacotherapy multiple stakeholders are involved, which are identified in this chapter. Clinically relevant pharmacogenes with their related PGx test are discussed, along with diagnostic test criteria to guide clinicians and policy makers in PGx test selection. The chapter further reviews the similarities and the differences between the guidelines of the Dutch Pharmacogenetics Working Group and the Clinical Pharmacogenetics Implementation Consortium which both support healthcare professionals in understanding PGx test results and help guiding pharmacotherapy by providing evidence-based dosing recommendations. Finally, clinical studies which provide scientific evidence and information on cost-effectiveness supporting clinical implementation of PGx in clinical care are discussed along with the remaining barriers for adoption of PGx testing by healthcare professionals.

Abstract
Purpose Due to the diversity within Europe, the implementation of pharmacogenomic testing in clinical practice faces specific challenges. In the context of the European pharmacogenomics implementation project “Ubiquitous Pharmacogenomics” (U-PGx; funded by the European Commission), we studied the current educational background. Methods We developed a questionnaire including 29 questions. It was spread out to healthcare professionals working at the future implementation sites (in Austria, Greece, Italy, Netherlands, Slovenia, Spain and Great Britain) of the U-PGx project in preparation of an educational programme. Aim of the survey was to analyse the current educational situation at the implementation sites. Results In total, 70 healthcare professionals participated in the survey. Of participants, 84.3% found pharmacogenomics relevant to their current practice, but experience was still rare. More than two-thirds (65.7%) did not order nor recommend a pharmacogenomic test in the past year. This was mainly attributed to not having enough knowledge on pharmacogenomics (40.0%). Needs were identified in application of pharmacogenomics (identifying drugs 41.4%, interpreting test results 37.2%) as well as in underlining mechanisms (better knowledge on drug metabolism 67.1%, better knowledge on basic principles of pharmacogenomics 60.0%). Conclusions This study analysed the specific attitudes, experience and education on pharmacogenomics of future users. There was a general positive attitude and interest towards pharmacogenomic testing. However, the grade of own experience, and knowledge about application and interpretation of pharmacogenomics caused uncertainty. Thus, education and training programmes may be helpful for implementation of pharmacogenomics at a homogenous level within Europe.
