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
OBJECTIVE The FACT-PGx study was conducted to analyze barriers to implementation of pharmacogenetic testing in psychiatric hospitals in Germany and to propose solutions for its faster and easier implementation in all hospitals. METHODS 104 patients (50% female) were genotyped and participated in the study. 67 completed a survey. To analyze the correlation between continuous data (age) of the survey, the wilcoxon rank test and for categorial data (education level, history of treatment and episodes), t-test was used. RESULTS No patient declined to be genotyped. 99% believed that genotyping could help to shorten their hospital stay. Patients >40 years of age and with higher educational levels were willing to pay for the PGx (p=0.009). On average, patients were willing to pay 117.42€ +/-140.49€ and to wait 15.83+/- 8.92 days for the results. Processes differed significantly between routine laboratory screening and PGx testing which could be a barrier for implementation. CONCLUSION Patients are not barriers to but enablers of an implementation of PGx. New process flows can be barriers, but can be overcome by optimization.

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
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.

Abstract
OBJECTIVES With increasing evidence for the clinical utility of pharmacogenomic (PGx) testing for depression, there is a growing need to consider issues related to the clinical implementation of this testing. The perspectives of key stakeholders (both people with lived experience [PWLE] and providers) are critical, but not frequently explored. The purpose of this study was to understand how PWLE and healthcare providers/policy experts (P/HCPs) perceive PGx testing for depression, to inform the consideration of clinical implementation within the healthcare system in British Columbia (BC), Canada. METHODS We recruited two cohorts of participants to complete individual 1-h, semi-structured interviews: (a) PWLE, recruited from patient and research engagement networks and organizations and (b) P/HCPs, recruited via targeted invitation. Interviews were audiotaped, transcribed verbatim, de-identified, and analysed using interpretive description. RESULTS Seventeen interviews were completed with PWLE (7 with experience of PGx testing for depression; 10 without); 15 interviews were completed with P/HCPs (family physicians, psychiatrists, nurses, pharmacists, genetic counsellors, medical geneticists, lab technologists, program directors, and insurers). Visual models of PWLE's and P/HCP's perceptions of and attitudes towards PGx testing were developed separately, but both were heavily influenced by participants' prior professional and/or personal experiences with depression and/or PGx testing. Both groups expressed a need for evidence and numerous considerations for the implementation of PGx testing in BC, including the requirement for conclusive economic analyses, patient and provider education, technological and clinical support, local testing facilities, and measures to ensure equitable access to testing. CONCLUSIONS While hopeful about the potential for therapeutic benefit from PGx testing, PWLE and P/HCPs see the need for robust evidence of utility, and BC-wide infrastructure and policies to ensure equitable and effective access to PGx testing. Further research into the accessibility, effectiveness, and cost-effectiveness of various implementation strategies is needed to inform PGx testing use in BC.

Abstract
Adverse drug reactions (ADRs) rank as one of the top 10 leading causes of death and illness in developed countries. ADRs show differential features depending upon genotype, age, sex, race, pathology, drug category, route of administration, and drug–drug interactions. Pharmacogenomics (PGx) provides the physician effective clues for optimizing drug efficacy and safety in major problems of health such as cardiovascular disease and associated disorders, cancer and brain disorders. Important aspects to be considered are also the impact of immunopharmacogenomics in cutaneous ADRs as well as the influence of genomic factors associated with COVID-19 and vaccination strategies. Major limitations for the routine use of PGx procedures for ADRs prevention are the lack of education and training in physicians and pharmacists, poor characterization of drug-related PGx, unspecific biomarkers of drug efficacy and toxicity, cost-effectiveness, administrative problems in health organizations, and insufficient regulation for the generalized use of PGx in the clinical setting. The implementation of PGx requires: (i) education of physicians and all other parties involved in the use and benefits of PGx; (ii) prospective studies to demonstrate the benefits of PGx genotyping; (iii) standardization of PGx procedures and development of clinical guidelines; (iv) NGS and microarrays to cover genes with high PGx potential; and (v) new regulations for PGx-related drug development and PGx drug labelling.

Abstract
In psychiatry, the selection of antipsychotics and antidepressants is generally led by a trial-and-error approach. The prescribing of these medications is complicated by sub-optimal efficacy and high rates of adverse drug reactions (ADRs). These both contribute to poor levels of adherence. Pharmacogenetics (PGx) considers how genetic variation can influence an individual’s response to a drug. Pharmacogenetic testing is a tool that could aid clinicians when selecting psychotropic medications, as part of a more personalized approach to prescribing. This may improve the use of and adherence to these medications. Yet to date, the implementation of PGx in mental health environments in the United Kingdom has been slow. This review aims to identify the current barriers and enablers to the implementation of PGx in psychiatry and determine how this can be applied to the uptake of PGx by NHS mental health providers. A systematic searching strategy was developed, and searches were carried out on the PsychInfo, EmBase, and PubMed databases, yielding 11 appropriate papers. Common barriers to the implementation of PGx included cost, concerns over incorporation into current workflow and a lack of knowledge about PGx; whilst frequent enablers included optimism that PGx could lead to precision medicine, reduce ADRs and become a more routine part of psychiatric clinical care. The uptake of PGx in psychiatric care settings in the NHS should consider and overcome these barriers, while looking to capitalize on the enablers identified in this review.

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
BACKGROUND To describe trends and clinical experiences in applying commercial pharmacogenetic testing among pediatric patients with neuropsychiatric disorders. METHODS Demographic and clinical data of patients receiving GeneSight® testing from January 2015 to November 2016 at an urban pediatric hospital were retrospectively extracted from medical charts. Outcome data included pharmacogenetic test results and medication prescriptions before and after the test. RESULTS A total of 450 patients (12.1 ± 4.3 years) diagnosed with anxiety disorder, attention deficit hyperactivity disorder, developmental disorders including autism, and/or a mood disorder received testing, and 435 of them were prescribed medications. Comparing data before and after testing, the total number of psychotropic prescriptions were reduced by 27.2% and the number of prescribed medications with severe gene-drug interactions decreased from 165 to 95 (11.4% to 8.9% of total medications prescribed). Approximately 40% of actionable genetic annotation were related to CYP2CD6 and CYP2C19. Patients of Asian descent had significantly higher likelihood than other races of being classified as poor to intermediate metabolizers of antidepressants, mood stabilizers, and antipsychotics (p = 0.008, 0.007, and 0.001, respectively). Diagnoses, including autism spectrum disorder, were not associated with increased risks of severe gene-drug interactions. CONCLUSIONS Pharmacogenetic testing in child and adolescent psychiatry is currently based on few clinically actionable genes validated by CPIC and/or FDA. Although this approach can be moderately utilized to guide psychotropic medication prescribing for pediatric patients with psychiatric disorders, clinicians should cautiously interpret test results while still relying on clinical experience and judgment to direct the final selection of medication.

Abstract
Psychiatric disorder management is based on the prescription of psychotropic drugs. Response to them remains often insufficient and varies from one patient to another. Pharmacogenetics explain part of this variability. Pharmacogenetic testing is likely to optimize the choice of treatment and thus improve patients’ care, even if concerns and limitations persist. This practice of personalized medicine is not very widespread in France. We conducted a national survey to evaluate the acceptability of this tool by psychiatrists and psychiatry residents in France, and to identify factors associated with acceptability and previous use. The analysis included 397 observations. The mean acceptability score was 10.70, on a scale from 4 to 16. Overall acceptability score was considered as low for 3.0% of responders, intermediate for 80.1% and high for 16.9%. After regression, the remaining factors influencing acceptability independently of the others were prescription and training history and theoretical approach. The attitude of our population seems to be rather favorable, however, obvious deficiencies have emerged regarding perceived skills and received training. Concerns about the cost and delays of tests results also emerged. According to our survey, one of the keys to overcoming the barriers encountered in the integration of pharmacogenetics seems to be the improvement of training and the provision of information to practitioners.

Abstract
OBJECTIVE Pharmacogenomic testing (PGx) is expanding into psychiatric care. PGx could potentially offer a unique benefit to psychiatric patients, providing information about patients' reaction to medications that could reduce the time and financial burdens of drug optimization. The aims of this study were to: (1) examine psychiatry patients' familiarity and interest in PGx, and (2) explore how Uncertainty Management Theory relates to PGx testing in psychiatry. METHOD We surveyed psychiatric patients, measuring their PGx familiarity and interest, attitudes toward PGx testing, and preference for managing illness uncertainty. RESULTS We analyzed data from 598 patients. Patients' familiarity of PGx was low, but interest was high. Thirty percent of patients were familiar with the test from communication with their healthcare provider or their own online health information seeking. A preference for seeking information was a significant positive predictor of testing interest (p < .001). CONCLUSION Psychiatric patients were interested in PGx testing, regardless of their uncertainty management preferences. PRACTICE IMPLICATIONS This study is one of the first to examine psychiatric patients' perspectives on PGx testing in mental health care. Our findings show that psychiatric patients are interested in the test and are familiar enough with PGx to be included in future research on the topic.

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.

Introduction: Pharmacogenomic tests relevant to neuropsychiatric medications have been clinically available for more than a decade, but the utility of regular testing is still unknown. Tests available include both pharmacokinetic and pharmacodynamic targets. The potential practice benefits vary with each target. Methods: A 10-year literature review was completed utilizing the PubMed database to identify articles relating to the specific pharmacogenomic targets discussed. Further article selection was based on author review for clinical utility. Results: The clinical dosing guidance available for neuropsychiatric medications such as selective serotonin reuptake inhibitors and tricyclic antidepressants with varying genotypes is useful and has strong evidence to support testing, but it is limited to mainly pharmacokinetic application. Pharmacodynamic targets are gaining additional evidence with increased research, and although the mechanisms behind the potential interactions are scientifically sound, the bridge to clinical practice application is still lacking. Discussion: Although the benefits of decreasing adverse reactions and improving response time are appealing, clinicians may not utilize pharmacogenomic testing in routine practice due to several barriers. Further clinical guidance and studies are needed to support testing for other neuropsychiatric medications and targets.

Abstract
AIM This study aims to assess the attitudes and opinions of clinicians practicing in psychiatry toward pharmacogenomic testing, and in so doing elicits possible barriers and risks to employ this technology in patient care. MATERIALS & METHODS Doctors and pharmacists presently practicing in psychiatry were invited to participate in an anonymous web-based survey. Besides information on participant characteristics and experience in psychiatry, specific themes on pharmacogenomics including self-assessed competency, perceived usefulness in clinical situations, perceived risks and preferred mode of education were evaluated. RESULTS A total of 81% of respondents believed that pharmacogenomic testing would be useful for identifying suitable treatments and 71% believed that pharmacogenomic testing would be useful for medication intolerance. However, only 46.4% felt competent to order these tests. There were significant differences in responses for gender, doctors versus pharmacists and seniority in position. A total of 94.3% of respondents were concerned about costs and 84.5% were concerned about the lack of clear guidelines on its use. A total of 98.5% of respondents were keen on learning more about the applicability of pharmacogenomics, and the most preferred format of education was a lecture (44.5%). CONCLUSION Most clinicians acknowledge the potential of pharmacogenomic testing in clinical practice. However, concerns with regard to its cost-effectiveness and the lack of clear guidelines are possible barriers to its clinical implementation.
