Pharmaceutical poisoning is a significant global public health concern, causing approximately 190,000 deaths annually. This scoping review aims to comprehensively map the available literature on pharmaceutical poisoning and compare patterns between high-income countries (HICs) and low-middle-income countries (LMICs). A systematic search was performed across the following databases: Embase, PubMed, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and CINAHL. Studies included were from 1 January 2011 to 31 December 2020, in English, with full text available. Seventy-nine articles were included in the study; 21 were from LMICs and 58 were from HICs. Toxic exposure was largely intentional (77%) in LMICs and accidental (68%) in HICs. Drugs acting on the nervous system were responsible for 95% of toxicities worldwide with analgesics accounting for the largest subtherapeutic group in both LMICs (40%) and HICs (58%). Notable statistics were that HICs accounted for 99% of opioid overdoses, and LMICs accounted for 19% of anti-epileptic-induced toxicities. Overall, the medical outcomes due to poisonings were generally worse in LMICs. The review provides possible interventions to target specific geographic locations, based on the trends identified, to reduce the burden worldwide. Many gaps within the literature were recognised, calling for more robust analytical research. Full article

Background: Self-medication (SM) is a growing phenomenon worldwide that has recently been classified as one of the most serious public health problems. SM can result in an incorrect self-diagnosis, inappropriate treatment, potential adverse reactions, interactions, and the masking of more sinister disease. Objectives: To assess the prevalence of SM practices amongst healthcare professionals and the general population in Saudi Arabia and to identify the sociodemographic contributing factors to this practice. Methods: A total of 540 participants were enrolled in this study. Participants were asked to complete the study questionnaire comprising two sections to gather demographic information and to collect data regarding SM practice. Results: The prevalence of SM practice among the study participants was 78.6%, and it was the highest among the middle age groups of (21–40 years) 82% compared to the younger and older age groups. The observed prevalence was higher in the female participants (53.7%) and those who live alone. Type of education did not affect the attitude of SM (p = 0.374); however, level of education strongly affected the prevalence of the SM, with higher incidence among university graduates (p < 0.001). Analgesics with antipyretics properties were the most self-medicated drugs. Patients considering their illnesses minor was the main reason behind the high prevalence of this practice. Among healthcare professions the highest prevalence of SM was found among pharmacists (95%), followed by physicians, nurses, and other medical practitioners. Conclusion: The general population should be better educated and made conscious about the consequences, risks, and side effects of SM. Awareness campaigns may prove to be useful in this matter, allowing the patient to consider the appropriateness of this practice. Individuals in the age group of 21–40 years, females, and those who live alone should be considered priority target populations in the design and implementation of SM awareness projects.

Linezolid (LZD) has a longstanding reported association with the onset of serotonin toxicity (ST), secondary to drug–drug interactions with serotoninergic agents. There have been no conclusive data supporting the incidence or contributing risk factors to date. The study evaluated the incidence of ST in patients treated with LZD and serotonergic agents concomitantly versus LZD alone. The secondary objectives included a comparison of ST incidence in patients treated with one serotonergic agent + LZD versus two or more serotonergic agents + LZD. The studies used for this meta-analysis were retrieved from PubMed, Scopus, and Google Scholar. All studies including a comparison between LZD alone and LZD + a serotonergic agent published between 1 January 2000 and 1 October 2023 and meeting the quality standards were considered for inclusion. Fourteen studies were identified, with five meeting all inclusion and exclusion criteria with no significant heterogeneity. For the analysis of LZD monotherapy vs. SA combination therapy, four studies with 6025 patients total were analyzed and yielded an odds ratio of 1.78 (CI [1.04, 3.02]; I² = 49%; GRADE certainty: low). Four studies and 2501 patients were included in the analysis of one versus more than one SA with an odds ratio of 5.18 (CI [1.05, 25.49]; I² = 44.87; GRADE certainty: moderate). The Newcastle–Ottawa score, visual inspection of the funnel plot, and Egger’s statistic were used to evaluate quality and heterogeneity. The Peto method was used to calculate the summary odds ratios. All analyses were performed using Comprehensive Meta-Analysis version 3.0 and R, while GRADE was used to evaluate the quality of the final recommendation. The number of concomitant serotonergic agents may play a role in the development of serotonin toxicity in patients prescribed linezolid. In patients requiring linezolid therapy and serotonergic agents, risk versus benefit analysis should pay attention to the number of interacting drugs. Full article

Background: Immunising the population became important during the COVID-19 pandemic. Community pharmacies in Norway collaborated with municipalities to offer a vaccination services to increase the vaccination rate. Only some pharmacies were allowed to offer this service in the pandemic’s early phase. This study learns about pharmacists’ experiences during this first period of COVID-19 vaccination services in community pharmacies, which is relevant for informing policy and organisational decision makers about the feasibility and acceptability of pharmacy vaccination. Methods: Individual interviews were conducted with 13 pharmacists in community pharmacies offering a COVID-19 vaccination service. Informants were recruited from the eleven pharmacies that first offered COVID-19 vaccinations. The key themes in the interview were COVID-19 vaccination, what the pharmacists think about the vaccination service, and how it is performed. The data were analysed using systematic text condensation. Results: Three main themes and eight subthemes were identified. The main themes were creative solutions, organising and making resources available, and professionally satisfying and an important mission. The interviewed pharmacists experienced the COVID-19 vaccination service as hectic but something important that they would prioritise. They experienced their efforts to be substantial in the pandemic’s early phase. Conclusions: Pharmacists in community pharmacies were a resource for increasing the vaccination rate during the COVID-19 pandemic. The pharmacies’ easy accessibility and the pharmacists’ ability to adjust their daily workflow for a new service should be considered when an expanded healthcare service is needed. Full article

Inappropriate use of dietary supplements by patients might exacerbate their diseases. The aim of this study was to clarify the situation of dietary supplement use for disease treatment among patients. A cross-sectional online questionnaire survey was conducted between 18 and 30 November 2022. A preliminary survey revealed that the proportion of patients who used dietary supplements to treat their disease ranged from 7.7% (cancer) to 28.2% (menopausal disorder). In the actual survey, across all diseases, patients who used dietary supplements for treatment purposes were satisfied with their therapeutic effects. Information obtained via the internet was the most common reason given for starting to use supplements. The proportions of patients who used supplements concurrently with medicine ranged from 25.4% (liver disease) to 72.2% (mental disorder). Most users of supplements did not consult with their physicians or pharmacists about them. However, patients preferred face-to-face consultation with a physician or pharmacist when discussing the concomitant use of medicines. In conclusion, the role of pharmacists is important for the appropriate use of dietary supplements among patients, especially concomitant use with medicines. More awareness about dietary supplements is needed for healthcare professionals to consult with their patients. Full article

(1) Background: This retrospective analysis utilizing electronic medical record (EMR) data from a tertiary integrated health system sought to identify patients and prescribers who would benefit from pharmacogenomic (PGx) testing based on Clinical Pharmacogenetics Implementation Consortium (CPIC) guidelines. (2) Methods: EMR data from a clinical research data warehouse were analyzed from 845,518 patients that had an encounter between 2015 and 2019 at an academic medical center. Data were collected for 42 commercially available drugs with 52 evidence-based PGx guidelines from CPIC. Provider data were obtained through the EMR linked by specialty via national provider identification (NPI) number. (3) Results: A total of 845,518 patients had an encounter in the extraction period with 590,526 medication orders processed. A total of 335,849 (56.9%) patients had medication orders represented by CPIC drugs prescribed by 2803 providers, representing 239 distinct medications. (4) Conclusions: The results from this study show that over half of patients were prescribed a CPIC actionable medication from a variety of prescriber specialties. Understanding the magnitude of patients that may benefit from PGx testing, will enable the development of preemptive testing processes, physician support strategies, and pharmacist workflows to optimize outcomes should a PGx service be implemented.

Purposefully developed professional identity formation (PIF) learning activities within the didactic curriculum provide crucial groundwork to complement PIF within authentic settings. The aim of this didactic exercise was to explore the impact upon student pharmacists’ PIF after viewing, analyzing, and reflecting upon a simulated pharmacist–patient encounter (PPE). A 12 min role-play video was created, featuring a pharmacist counseling a standardized patient on a new medication regimen; foundational principles of medication safety, health literacy, social determinants of health, empathic communication, and motivational interviewing were included in the counseling, with some aspects intentionally performed well, others in need of improvement. Also included were the patient’s varied reactions to the counseling. Students assumed the observer role and learned vicariously through viewing the PPE. Postactivity debriefs included justifying a foundational principle performed well by the pharmacist, and another in need of improvement, and a self-reflection essay expressing the impact of viewing the PPE on their PIF, from which extracts were thematically analyzed for impact. The main themes of the impact included increased awareness of counseling techniques, patient-friendly medical jargon, patient perspectives/empathy, positive and negative pharmacist role-modeling, and the value of the observer role. This PPE exercise enhanced PIF in terms of students thinking, acting, and feeling like a pharmacist, based on students’ self-reflections, which most often referenced effective pharmacist–patient communication and enacting optimal patient care.

Preconception care is the prevention and management of biomedical, behavioral, and social risk factors to improve pregnancy outcomes and overall health for reproductive-age patients. A community-based pharmacist-directed preconception care outreach program was developed for women ages 18–45 years living in a rural maternity care desert to help them identify potential health risks and provide them with the needed education, counseling, or referrals to address these risks. Supervised student pharmacists, pharmacy practice residents, and pharmacy faculty from a local University collaborated to provide this program at four community events in conjunction with a mobile health clinic. A summative evaluation was performed after the events concluded, modeled after the RE-AIM framework. One hundred and forty-one women were served by the outreach program. Nearly 98% reported at least one preconception health risk, and 45% reported a barrier preventing them from being able to have an appointment with a physician in the last year. The outreach program was feasible to implement and can be adapted to different settings. Pharmacist-directed outreach programs in rural communities may benefit patients who are not receiving or do not have access to such care in traditional healthcare settings. Full article

This systematic review compared the efficacy and tolerance of oral antipsychotics (APDs) used in the treatment of schizophrenia following the PRISMA-P© statement (n = 21). The primary outcomes of interest were clinical response measured with symptoms’ improvement, tolerance to side effects and discontinuation reasons. There was better individual patients’ response to aripiprazole vs. ziprasidone and quetiapine ((CDSS p = 0.04), BPRS p = 0.02, YMRS p = 0.001) and ziprasidone vs. quetiapine (CGI p = 0.02, CDSS p = 0.02). Aripiprazole was more tolerated than risperidone, ziprasidone and quetiapine (p < 0.05). Quetiapine was more tolerated than aripiprazole, ziprasidone and risperidone (p < 0.05). Ziprasidone was more tolerated than quetiapine haloperidol and olanzapine (p < 0.05). Risperidone was more tolerated than olanzapine (p = 0.03) and haloperidol was more tolerated than olanzapine and quetiapine (p < 0.05). Olanzapine caused less discontinuation than quetiapine; quetiapine caused less discontinuation than ziprasidone, aripiprazole and haloperidol; ziprasidone caused less discontinuation than quetiapine, aripiprazole and haloperidol; aripiprazole caused less discontinuation than quetiapine, ziprasidone and olanzapine and olanzapine caused less discontinuation than ziprasidone and haloperidol (p < 0.05). It was concluded that individual patient clinical response, tolerance to side effects and life-threatening side effects remain the most reliable basis for selecting and continuing the use of APD.

Background: Information regarding off-label and unlicensed medicine use among South African children is limited. This is a concern as the prescribing of off-label and unlicensed medicines can lead to issues of effectiveness and safety as well as raise liability issues in the event of adverse events. This potentially exposes physicians to legal penalties. Consequently, we sought to determine the prevalence of off-label and unlicensed medicine use among paediatric patients in South Africa to provide future direction. Methods: This study retrospectively examined the use of medicine in a point-prevalence survey study (PPS) involving paediatric patients aged (0–2 years) admitted to selected public hospitals in Gauteng Province, South Africa. Data were collected per hospital over two days between February 2022 and July 2022. Demographics, duration of treatment, diagnosis, and medicines prescribed were collected from patient medical records using a mobile application. Prescribed medicines were reviewed against the medicine formularies and other databases to assess their appropriateness. Results: From three academic hospitals, 184 patient records were reviewed. A total of 592 medicines were dispensed, of which 379 (64.0%) were licensed and 213 (36.0%) were used off-label/unlicensed for paediatric patients 0–2 years of age. The most prevalent off-label and unlicensed medicines were multivitamins (n = 32, 15.0%) and ampicillin injections (n = 15, 7.0%). Conclusion: The frequency of unlicensed and off-label medicine prescribing shown in this study is consistent with the literature and can be considered high. This practice can pose a risk because it adversely affects patients if not properly regulated. Attention is needed to ensure future high-quality, safe, and effective use of medicines. Full article

The pharmacist prescribing service was legally permitted in 2019 in Switzerland to face challenges in the health system; however, there has been a lack of implementation. The aims of this study were to identify implementation factors and to evaluate pharmacy association interventions that aim to support implementation. A qualitative study with two methods was carried out: (1) twelve semi-structured interviews with community pharmacists were recorded, transcribed, and a thematic analysis was carried out using the Consolidated Framework of Implementation Research (CFIR); (2) questionnaires were submitted to the six pharmacy associations of French-speaking Switzerland. The main barriers found were non-reimbursement by health insurance companies, medications’ lack of clinical relevance, a negative perception of GPs, and a lack of time. The main facilitators were the availability of service information, pharmacies belonging to chains/groups, a reduction in the medical consultation burden, and the accessibility of pharmacies. Five associations answered, revealing different initiatives supporting implementation, but none of them had strategies at the political level nor communication strategies aimed at patients or GPs. Based on the CFIR, the most frequent implementation factors were highlighted, and this classification facilitates the transposition of the results to other contexts. The results will allow the development of targeted strategies and add the role of the pharmacy associations, which should be considered in future studies. Full article

Pharmacy schools recognize the need for flexibility and comprehensive curricular transformation with a competency-based focus to effectively prepare for the evolving practitioner competencies and challenges of the pharmacy profession. The curricular implementation of evidence-based teaching and learning theories and practices demands educator proficiency through skills development with indispensable faculty leadership support. Our scoping review of online databases and pharmacy education-related journals aims to identify faculty development interventions or teaching proficiency programs that integrate educational and pedagogical theories. Original studies and reviews published between 2010 and 2022 were screened based on four inclusion criteria. Thirty-four manuscripts were eligible for full-text analysis, of which seven results referenced target faculty pedagogy knowledge development. Nine key messages, as Results Statements, synthesize and provide a framework for our results analysis. An ongoing Hungarian intervention model of comprehensive faculty development with strong interdisciplinary cooperation is discussed in our study to illustrate the applicability of the Results Statements through each stage of the process. Educator motivation and relatedness to students or awareness of the educator roles are intrinsic factors, which may not be easily detectable yet significantly impact teaching proficiency and student learning outcomes. The integration of evidence-based pedagogical knowledge and training in educator proficiency development contributes to the sustainability and cost-effectiveness of faculty interventions.

Problematic sleep or insomnia has been a recognised issue for many individuals in society, and university students can be of particular concern due to unique academic pressures. A systematic review was designed to summarise the current evidence about the extent of insomnia medication used by university students and identify characteristics of those more willing to use medication to manage insomnia. Searches were undertaken using Psych INFO, PubMed, Embase, and Web of Science, resulting in 25 eligible studies across multiple countries between 1994 and 2020. The prevalence of sleep medication use by students varied widely, from 2% to 41.2%, with an average of 13.1%. Female gender, students experiencing poor sleep, smoking, drinking stimulant beverages, and undertaking fewer physical activities were associated with the use of insomnia medication. Insomnia medication use exists within university student populations but appears to vary considerably worldwide; identifying multiple population characteristics associated with such use would offer opportunities to identify and support those affected.

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

Acute pyelonephritis (APN) is a relatively common community-acquired infection, particularly in women. The early appropriate antibiotic treatment of this potentially life-threatening infection is associated with improved outcomes. The international management guidelines for complicated urinary tract infections and APN recommend using oral antibiotics with <10% resistance among urinary pathogens. However, increasing antibiotic resistance rates among Escherichia coli and other Enterobacterales to fluoroquinolones, trimethoprim-sulfamethoxazole (TMP-SMX), and beta-lactams has left patients without reliable oral antibiotic treatment options for APN. This narrative review proposes using precision medicine concepts to improve empirical antibiotic therapy for APN in ambulatory settings. Whereas resistance rates to a particular antibiotic class may exceed 10% at the population-based level, the predicted antibiotic resistance rates based on patient-specific risk factors fall under 10% in many patients with APN on the individual level. The utilization of clinical tools for the prediction of fluoroquinolones, TMP-SMX, and third-generation cephalosporin resistance improves the ambulatory antibiotic management of APN. It may also reduce the need to switch antibiotic therapy later based on the in vitro antibiotic susceptibility testing results of bacterial isolates in urinary cultures. This approach may mitigate the burden of increasing antibiotic resistance in the community by ensuring that the initial antibiotic prescribed has the highest likelihood of treating APN appropriately.

Persons diagnosed with dementia are often faced with challenges related to polypharmacy and inappropriate medication use and could benefit from regular medication reviews. However, the benefit of such reviews has not been examined in this population. Therefore, the current scoping review was designed to identify the gaps in the current knowledge regarding the impact of medication reviews on the clinical outcomes in older adults with dementia. Relevant studies were identified by searching three databases (Ovid MEDLINE, Ovid EMBASE, and Scopus) from inception to January 2022 with a combination of keywords and medical subject headings. After the removal of duplicates and ineligible articles, 22 publications of the initial 8346 were included in this review. A total of 57 outcomes were identified, including those pertaining to the evaluation of medication use (n = 17), drug-related interventions (n = 11), drug-related problems (n = 10), dementia-related behavioral symptoms (n = 8), cost-effectiveness (n = 2), drug-related hospital admissions (n = 1), as well as outcomes classified as other (n = 7). Gaps identified through this scoping review included the paucity of studies measuring the impact of medication reviews on the medication management capacity and medication adherence, quality of life, and mortality.

The aim of this systematic review was to identify and critically appraise the available evidence regarding solid oral dosage forms (SODFs), e.g., tablets, and challenges regarding the oral administration of medicine to inpatients in a variety of healthcare settings such as (1) hospitals, (2) nursing homes and (3) long-term stay units (LTSUs). A literature search was undertaken in September 2021 and repeated in June 2023 in the following databases: PubMed, EMBASE, CINAHL, Scopus, Web of Science, The Cochrane Library, PsycINFO and ProQuest. A Microsoft Excel^® spreadsheet was devised to collate the following data from each eligible study: study author and year, country, number of participants, title, duration (follow-up period), study design, inclusion and exclusion criteria, method and data collection, relevant outcomes, and key findings. A total of 3023 records were identified, with 12 articles being included in the final systematic review. Seven of the twelve studies reported on the prevalence of difficulties swallowing SODFs, which varied from 10–34.2%. Nine of the twelve studies reported the methods used to manipulate SODFs, with the most reported method being tablet crushing. Given the prevalence of swallowing difficulties and the subsequent crushing of medicines in response to this, it is evident that concerns should be raised regarding the potential for a medication administration error to occur.

Drugs can become short in supply for many reasons including increased demand and reduced production. Drug shortages have the potential to impact patients and pharmacists. This study aimed to highlight the challenges pharmacists face and the constraints of how they manage drug shortages. An online survey was designed with its link distributed electronically to community pharmacists in the UK with the assistance of pharmacy organizations during the period from September to December 2021. Survey data were analysed using descriptive statistics. A total of 83% of the respondents (n= 100) were experiencing drug shortages three or more times per week, and more than 70% of these spent 1–3 h per week dealing with them. A total of 93% of the respondents indicated that the issue of drug shortages was a problem for them, and 61% reported that it has worsened since the start of the pandemic. In addition, 65% of the respondents believed that drug shortages had had an impact on patient care. Drug shortages were shown to impact on the pharmacists’ workloads with a potential to affect the quality of patient care. There was a variation between how pharmacists dealt with drug shortages, which needs to be explored further with the reasons behind it. Full article
