PGx Education Research Articles

Analysis of the current situation of pharmacogenomics in terms of educational and healthcare needs in Egypt and Lebanon.

Pharmacogenomics (PGx) is a practice that investigates the link between genetic differences and drug response in patients. This can improve treatment effectiveness and reduce harmful side effects. However, has yet to be adequately realized in developing nations. Three surveys were conducted between November 2022 to March 2023 in Egypt and Lebanon. The first survey assessed availability of PGx testing in different healthcare facilities; the second one assessed knowledge, interest and attitude toward learning about PGx among pharmacists and physicians; and the third one assessed interest in providing PGx education at academic levels. In Egypt, a few of the surveyed healthcare facilities are conducting some form of pharmacogenetic testing. In Lebanon, very few germline pharmacogenomic tests are offered in Greater Beirut's leading hospitals, and no other testing was recorded. PGx education attracts considerable interest, with 34.3% of pharmacists very interested and 48.8% interested. Similarly, 24.8% of total physicians were very interested while 44.8% were interested. Academic professionals in the surveyed institutions in both countries agreed on the need for educational programs in PGx and 78.2% agreed that there were good opportunities for implementing PGx testing. These findings clearly indicate the need to develop and implement educational programs in PGx in the Middle-East.

Pharmacogenomics for Prader-Willi syndrome: caregiver interest and planned utilization.

Aim: The study aim was to determine caregiver interest and planned utilization of pharmacogenomic (PGx) results for their child with Prader-Willi syndrome. Methods: Caregivers consented to PGx testing for their child and completed a survey before receiving results. Results: Of all caregivers (n=48), 93.8% were highly interested in their child's upcoming PGx results. Most (97.9%) planned to share results with their child's medical providers. However, only 47.9% of caregivers were confident providers would utilize the PGx results. Conclusion: Caregivers are interested in utilizing PGx but are uncertain providers will use these results in their child's care. More information about provider comfort with PGx utilization is needed to understand how PGx education would benefit providers and ultimately patients with PGx results.

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

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. 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. 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. 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.

Pharmacogenomic testing in oncology: a health system's approach to identify oncology provider perspectives.

Aim: Identify oncology healthcare providers' attitudes toward barriers to and use cases for pharmacogenomic (PGx) testing and implications for prescribing anticancer and supportive care medications. Materials & methods: A questionnaire was designed and disseminated to 71 practicing oncology providers across the MedStar Health System. Results: 25 of 70 (36%) eligible oncology providers were included. 88% were aware of PGx testing and 72% believed PGx can improve care. Of providers who had ordered a medication with PGx implications in the past month, interest in PGx for anticancer (90-100%) and supportive care medications (>75%) was high. Providers with previous PGx education were more likely to have ordered a test (odds ratio: 7.9; 95% CI: 1.1-56; p=0.0394). Conclusion: Oncology provider prescribing practices and interest in PGx suggest opportunities for implementation.

Psychiatric mental health nurse practitioner student knowledge and perceptions of pharmacogenetic testing.

Psychotropic medications are typically prescribed in a trial-and-error fashion, and some providers are beginning to utilize pharmacogenetic testing (PGx) as a supplemental prescribing tool in treatment decision making. PGx testing shows potential in enhancing provider insights into personalized prescribing for patients by examining genetic information related to drug metabolism. Literature points to providers' lack of knowledge in PGx interpretation as a main barrier, including psychiatric mental health nurse practitioners (PMHNPs). The aim of this study was to measure a difference, if any, in the knowledge and perceptions of PGx after implementation using a pre-post design. This study implemented an educational intervention on graduate nursing students (n = 15). Data were collected by using a pre- and post-interventional questionnaire. Results demonstrated a significant difference in findings related to students' knowledge (p < 0.001), students' skills related to pharmacogenetics, (p < 0.001), as well as students' perceived ability to implement pharmacogenetics into their practice, (p = 0.028). The authors propose that the knowledge gained from the study demonstrates the importance of introducing PGx education into the PMHNP curricula and to prepare future PMHNPs to confidently utilize PGx in their clinical practice.

Assessing pharmacogenomic literacy in China through validation of the Chinese version of the Minnesota Assessment of Pharmacogenomic Literacy.

Pharmacogenomics (PGx) implementation into clinical care is rapidly increasing in China. However, the extent to which the public understands PGx testing and important knowledge domains requiring patient education or counseling remains unclear. To address this, we created and validated the Chinese version of the Minnesota Assessment of Pharmacogenomic Literacy (MAPL-CTM ). The MAPL-C was developed by translating the English MAPL to Chinese following cross-cultural translation guidelines. An online survey validated the MAPL-C and assessed Chinese individuals' PGx literacy. Validation analyses were performed and associations of PGx literacy with participants' characteristics were quantified. Of 959 high-quality responses, the majority of respondents were Han Chinese (96.3%), men (54.5%), aged 18-29 years (70.9%), residing in China (97.3%), and had received college or higher education (95.0%). Out of 15 starting items developed to query specific predefined knowledge domains, two uninformative items were excluded, resulting in a 13-item MAPL-C. Chinese participants' MAPL-C performance was best explained by a three-factor model, encompassing PGx concepts and function, testing limitations, and privacy. Higher MAPL-C performance was associated with younger age, higher education, and previous genetic testing experience. Correct response rates for questions related to testing limitations were lower than those in other domains. The creation and validation of the MAPL-C fills a gap in determining PGx knowledge among Chinese speakers, quantifying PGx literacy within a Chinese cohort, and identifying response patterns and knowledge gaps. The MAPL-C can be useful in clinical practice to guide patient counseling, assess PGx education interventions, and quantify PGx knowledge in relation to outcomes in research studies involving Chinese participants.

Knowledge and attitudes of medical and pharmacy students about pharmacogenomics: a systematic review and meta-analysis.

Pharmacogenomics (PGx) is rapidly growing branch of molecular genetics with high potentials to influence therapeutics. This review evaluates knowledge and attitudes of medical and pharmacy students about PGx. A literature search was conducted in electronic databases and studies were selected by following precise eligibility criteria. After quality assessment, studies were reviewed systematically, and meta-analyses of proportions were performed to estimate response rates of students. Fifteen studies (5509 students; 69% [95% confidence interval (CI): 60%, 77%] females) were included. Among students, 28% [95%CI: 12, 46] had adequate PGx knowledge; 65% [95%CI: 55, 75] were willing to have PGx test for their own risk assessment; 78% [95%CI: 71, 84] had intention to incorporate PGx in future practice; and 32% [95%CI: 21, 43] were satisfied with current PGx component of curriculum. Age, advanced year of educational program, and more time spent in PGx education were positively associated with PGx knowledge and positive attitudes.

Lack of exposure to pharmacogenomics education among the health care providing students in the West Bank of Palestine.

Evaluating the knowledge in pharmacogenomics (PGx) is the first step toward the implementation of PGx testing in clinical practice. This survey aimed to evaluate the knowledge of PGx testing among healthcare providing students at the top-ranked university in the West Bank of Palestine. First an online questionnaire consisting of 30 questions regarding the demographic, knowledge, and attitude toward pharmacogenomics testing was structured and validated. Then the questionnaire was distributed to 1,000 current students from different fields. 696 responses was received. The results showed that almost half of the participants (n=355, 51.1%) have never took any courses about PGx during their university training. Only 81 (11.7%) of the students who took the PGx course stated that it helped them understanding how genetic variations affect drug response. The majority of the students were uncertain (n=352, 50.6%) or disagreed (n=143, 20.6%) that the lectures during university education described the effects of genetic variants on drug response. Although most of the students (70-80%) answered that genetic variants can indeed affect the drug's response, only 162 students (23.3%) responded that VKORC1 and CYP2C9 genotypes influence the response to warfarin. In addition, only 94 (13.5%) students were aware that many medicine labels include clinical information about PGx testing provided by the FDA. It is concluded from the results of this survey that there is a lack of exposure to PGx education associated with poor knowledge of PGx testing among the healthcare providing students in the West Bank of Palestine. It is recommended to include and improve the lectures and courses regarding PGx as this will have a major impact on precision medicine.

Experience, Knowledge, and Perceptions of Pharmacogenomics among Pharmacists and Nurse Practitioners in Alberta Hospitals.

Despite evidence of clinical utility and the availability of prescription guidelines, pharmacogenomics (PGx) is not broadly used in institutional settings in Canada. To inform future implementation, this study aimed to identify healthcare provider knowledge, experience, and perceptions of PGx in Alberta, Canada. An online 44-item survey was distributed to pharmacists, nurse practitioners, and physicians employed or contracted with Alberta Health Services from January to May 2022. Questions included: demographics, professional history, PGx education and exposure, knowledge, and ability to use PGx, and attitudes towards, feasibility, clinical utility, education, and implementation. Ninety-one pharmacists, 37 nurse practitioners, and 6 physicians completed the survey. Fifty-nine percent had 10 or more years of experience, and 71% practiced in urban settings. Only one-third had training in PGx, and one-quarter had used PGx. Most respondents (63%) had no knowledge of PGx resources, including the Pharmacogenomics Knowledge Base (75%), or the Clinical Pharmacogenetics Implementation Consortium guidelines (85%). While participants agreed that they understood genetic (75%) and PGx (63%) concepts, most disagreed with their ability regarding practical applications of PGx such as translating genotype to phenotype (74%) or counselling patients on results (66%). Participants agreed on the clinical utility of PGx in preventing adverse drug reactions (80%) and enhancing medication efficacy (77%), and identified oncology (62%), cardiovascular/stroke (60%), and psychiatry (56%) as therapeutic areas to consider implementation. At present, healthcare provider knowledge (87%), cost (81%), and limited guidelines/evidence (70%) are seen as the greatest barriers to implementation. Alberta healthcare providers have limited training, experience, or knowledge in PGx. However, most appear to have a positive outlook regarding clinical utility, especially within oncology, cardiology, and psychiatry. More effort is required to socialize the availability and quality of evidence and guidelines for the interpretation of PGx test results, address other knowledge gaps, and improve financial limitations.

Pharmacogenomics in psychiatry - the challenge of cytochromeP450 enzyme phenoconversion and solutions to assist precision dosing.

Pharmacogenomic (PGx) testing of cytochrome P450 (CYP) enzymes may improve the efficacy and/or safety of some medications. This isfacilitated by increased availability and affordability of genotyping, the development of clinical practice PGx guidelines and regulatory support. However, the common occurrence of CYP phenoconversion, a mismatch between genotype-predicted CYP phenotype and the actual CYP phenotype, currently limits the application of PGx testing for precision dosing in psychiatry. This review proposes a stepwise approach to assist precision dosing in psychiatry via the introduction of PGx stewardship programs and innovative PGx education strategies. A future perspective on delivering precision dosing for psychiatrists is discussed thatinvolves innovative clinical decision support systems powered by model-informed precision dosing.

The Efficacy of a Didactic and Case-Based Pharmacogenomics Education Program on Improving the Knowledge and Confidence of Alberta Pharmacists.

BackgroundPharmacogenomics (PGx) is the study of how genetic variations for functional proteins, such as metabolizing enzymes and drug receptors, impact drug pharmacokinetics and pharmacodynamics. In theory, pharmacists are well suited to utilize PGx in tailoring medications to patient genetics when providing medication therapy management services. However, PGx education needs to reach pharmacists prior to implementation. The aim of this study is to develop and evaluate a PGx course for pharmacists.MethodsA PGx education program was created and offered synchronously (virtual) and asynchronously (self-study) to pharmacists in Alberta, Canada. Lectures were delivered by experts live (virtual) with a question-and-answer period for synchronous sessions. These sessions were recorded for asynchronous delivery. Six case studies were discussed in large and small groups (“breakout rooms”) in synchronous sessions, and provided for self-study in the asynchronous subgroup. Topics included genetic and PGx concepts; therapeutic applications; ethical, legal, and social considerations; and practical implementation. Pre- and post-course surveys measured self-rated knowledge using a 5-point Likert Scale and tested objective knowledge with a graded quiz.ResultsThirty-six pharmacists completed the course and both surveys. Participants reported backgrounds in community (88.9%) and hospital (38.9%) practice. Prior education in PGx was reported by 44.4% from degree programs and 27.8% from continuing education. Overall responses to statements about confidence in PGx moved from a median of “Disagree” at baseline to “Agree” after receiving PGx education (2-point difference [1,2] on 5-point Likert Scale; p < 0.001), indicating an increase in self-assessed competency in PGx. Likewise, mean participant grades on the knowledge quiz improved (20.8±21.9% pre-course vs 70.2±19.1% post-course, p < 0.001). There was no difference in these results between synchronous and asynchronous groups.ConclusionA didactic and case-based PGx education program was effective at increasing pharmacist knowledge and confidence in PGx in both synchronous and asynchronous environments. Knowledge gained can be utilized in delivery of patient-centered, personalized medication therapy management in the pharmacy setting.

PGxKnow: a pharmacogenomics educational HoloLens application of augmented reality and artificial intelligence.

Aim: To develop and assess an augmented reality tool for pharmacogenomics (PGx) education based on artificial intelligence. Materials & methods: AHoloLens application was developed using feedback from three clinical PGx-trained pharmacists. 15Participants independently reviewed the application and assessed usability using the system usability scale (SUS). Results & conclusion: Eighteen different frames were developed. Each video module was 2-3min for the education. The application included textual information and 3D structures of PGx concepts. The mean SUSscore for 15 participants (11 pharmacy students and four pharmacists) was 83, with a standard deviation of 6.6. Results suggest that PGxKnow has the potential to bridge the gap in PGx education, further widespread utilization of PGx and boost its impact on precision medicine.

Perception and knowledge of pharmacogenetics among Brazilian psychiatrists

Pharmacogenetics (PGx) can optimize drug therapy in psychiatry and is particularly important in admixed populations. Here we developed and successfully validated a questionnaire for assessing the perception and knowledge of PGx among Brazilian psychiatrists. Overall, the participants showed some familiarity with PGx. Most psychiatrists reported to have knowledge of PGx and recognized its usefulness in psychiatry; however, they declared concerns regarding PGx education, the request of tests and their interpretation, cost-effectiveness, and ethical issues. PGx testing is relatively prevalent in their clinical practice, but education on the topic is lacking. Bivariate analysis revealed significant associations. Psychiatrists > 40 years of age more frequently had a positive perception of other clinicians’ familiarity with PGx. Psychiatrists in private health services showed less self-reported competency in the use of PGx testing. Furthermore, women had better perception of PGx education. The present study adds knowledge about PGx in psychiatry and encourages the development of educational and training resources for PGx to improve its clinical implementation.

Pharmacogenomics Implementation Training Improves Self-Efficacy and Competency to Drive Adoption in Clinical Practice.

Background: Administration of pharmacogenomics (PGx) testing in clinical practice has been suboptimal, presumably due to lack of PGx education. Here, we aim to evaluate the standpoint of PGx testing among a diverse group of healthcare professionals (HCPs) through conducting surveys before and after training. Materials and Methods: Training modules were designed to cover three key learning objectives and deployed in five sections. A pre- and post-training survey questionnaire was used to evaluate participants’ self-assessments on employing PGx in clinical practice. Results and Conclusion: Out of all enrollments, 102 survey responses were collected. Overall, respondents agree on the benefits of PGx testing, but have inadequate self-efficacy and competency in utilizing PGx data. Our results show that a 90 min long training significantly improves these, and could lead to greater anticipation of PGx adoption.

Development of a laboratory-based pharmacogenomics independent study and advanced pharmacy practice experience: Connecting basic science to clinical application

Background and purposeThe role of pharmacists in pharmacogenomics (PGx) use clinically is expanding, leading to increased pharmacy education requirements. Current reports indicate that PGx is primarily taught through didactic courses, indicating a need for applied coursework in pharmacy curricula, including laboratory exercises and clinical experiences. Such courses are instrumental in helping students connect the science of PGx to patient care. Educational activity and settingAn advanced PGx independent study and a similar advanced pharmacy practice experience (APPE) were developed. These courses included personal genetic testing, raw genetic sequence data analysis, and wet-laboratory genetic testing. The APPE included sessions with clinical pharmacists who use PGx and a genetic counselor, as well as a visit to a genetic reference laboratory. A pre−/post-examination and survey were used to measure the courses' effectiveness and student perceptions of their abilities, PGx, and course components. For this pilot study one student per course was evaluated. FindingsEach student completed all components of the courses successfully, supporting the feasibility of their implementation. Examination scores increased for both students with improvement in knowledge from basic genetics to clinical application. Both students also had a more positive perception of PGx after the courses and valued the various course components. SummaryThrough this unique course format, pharmacy students developed expertise in understanding and implementing PGx which allowed them to gain skills that go beyond an introductory course. Our experience may provide guidance to other pharmacy programs in adding more applied PGx education to their curricula.

Evaluation of the need for pharmacogenomics testing among physicians in the West Bank of Palestine

Pharmacogenomics (PGx) testing optimizes pharmacotherapy and reduces interindividual variation in drug responses. However, it is still not implemented in clinical practice in the West Bank of Palestine (WBP). The aim of this study was to determine the need for PGx education and testing among physicians from different specialties in WBP. This study used a cross-sectional survey that was administered to 381 physicians from different cities inWBP. The questionnaire consisted of 27 closed-ended questions that evaluate the exposure and attitude toward PGx education, the role of PGx testing in clinical practice, and the capabilities of physicians in PGx testing. It was found that exposure to PGx education is low, with most of the respondents (81.1%) answering that PGx was not an integral part of their medical education. The majority (>90%) of the participants agreed that PGx should be included in the medical school curriculum. It was also found that 58.5% of the participants agreed that PGx testing is relevant to their current clinical practice. In addition, most of the participant physicians (>60%) think that they are currently not capable of prescribing and making decisions for pharmacotherapy based on PGx testing. It is concluded that there is a high need for PGx education and implementation in clinical practice in WBP. We recommend adding PGx courses to the curricula of medical schools and going forward with the implementation of PGx testing in clinical practice in WBP.

Implementation of a pharmacist-provided pharmacogenomics service in an executive health program.

We describe the implementation of a pharmacist-provided pharmacogenomics (PGx) service in an executive health program (EHP) at an academic medical center. As interest in genomic testing grows, pharmacists have the opportunity to advance the use of PGx in EHPs, in collaboration with other healthcare professionals. In November 2018, a pharmacist-provided PGx service was established in the EHP at the University of Colorado Hospital. The team members included 3 physicians, a pharmacist trained in PGx, a registered dietitian/exercise physiologist, a nurse, and 2 medical assistants. We conducted 4 preimplementation steps: (1) assessment of the patient population, (2) selection of a PGx test, (3) establishment of a visit structure, and (4) selection of a billing model. The PGx consultations involved two 1-hour visits. The first visit encompassed pretest PGx education, review of the patient's current medications and previous medication intolerances, and DNA sample collection for genotyping. After this visit, the pharmacist developed a therapeutic plan based on the PGx test results, discussed the results and plan with the physician, and created a personalized PGx report. At the second visit, the pharmacist reviewed the PGx test results, personalized the PGx report, and discussed the PGx-guided therapeutic plan with the patient. Overall, the strategy worked well; minor challenges included evaluation of gene-drug pairs with limited PGx evidence, communication of information to non-EHP providers, scheduling issues, and reimbursement. The addition of a PGx service within an EHP was feasible and provided pharmacists the opportunity to lead PGx efforts and collaborate with physicians to expand the precision medicine footprint at an academic medical center.

Providers'perspectives on the clinical utility of pharmacogenomic testing in pediatric patients.

Aim: To assess providers' knowledge, attitudes, perceptions, and experiences related to pharmacogenomic (PGx) testing in pediatric patients. Materials & methods: An electronic survey was sent to multidisciplinary healthcare providers at a pediatric hospital. Results: Of 261 respondents, 71.3% were slightly or not at all familiar with PGx, despite 50.2% reporting prior PGx education or training. Most providers, apart from psychiatry, perceived PGx to be at least moderately useful to inform clinical decisions. However, only 26.4% of providers had recent PGx testing experience. Unfamiliarity with PGx and uncertainty about the clinical value of testing were common perceived challenges. Conclusion: Low PGx familiarity among pediatric providers suggests additional education and electronic resources are needed for PGx examples in which data support testing in children.

Assessing the knowledge, perceptions, and practices of primary care clinicians toward pharmacogenetics

AbstractIntroductionPharmacogenetics (PGx) testing is becoming increasingly available to patients and clinicians, but investigations of PGx testing in primary care and the pharmacist's role in educating clinicians have been limited.ObjectivesThe objectives of this study were to: (a) determine the utilization of PGx testing in primary care clinics, (b) identify how clinicians document and act on PGx test results, and (c) determine clinician interest in PGx education or consultation from pharmacists.MethodsA 16‐item survey was distributed via email. Eligible participants included physicians, physician assistants, nurse practitioners, and pharmacists who work in family medicine, general medicine, geriatric, or pediatric primary care clinics at one academic medical center. Descriptive statistics were used to characterize the frequency of PGx tests ordered in primary care clinics, provider comfort with PGx test interpretation, documentation practices, and interest in PGx education or consultation from pharmacists.ResultsThe overall survey response rate was 15.8% (n = 55). Most respondents were physicians (84%). Nearly 40% of respondents reported having a patient bring PGx test results to a visit, while only 9% reported ordering a PGx test. Documentation practices were variable, and response to PGx results was most commonly no change in therapy (52%). Only two (3.6%) respondents agreed with the statement, “I feel confident in my ability to interpret PGx test results,” and the majority reported interest in PGx education. Eighty percent of respondents reported they would be likely or very likely to consult a PGx‐trained pharmacist for help interpreting PGx results.DiscussionClinicians in this survey were more likely to have patients bring in results than to order PGx tests, did not feel confident in result interpretation, and expressed interest in working with pharmacists for PGx test interpretation. This research can help guide the development of PGx‐focused pharmacy services and education for clinicians who are encountering PGx testing in their practice.
