Effect of pharmacist care on clinical outcomes and therapy optimization in perioperative settings: A systematic review.

DISCLAIMER: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. PURPOSE: Integration of pharmacists into the perioperative practice has the potential to improve patients' clinical outcomes. The aim of this systematic review is to systematically investigate the evidence on the roles of pharmacists in perioperative settings and the effects of pharmacist interventions on clinical outcomes and therapy optimization. METHODS: A protocol-led (CRD42023460812) systematic review was conducted using search of PubMed, Embase, CINAHL and Google Scholar databases. Studies that investigated the roles and impact of pharmacist-led interventions in the perioperative settings on clinical outcomes were included. Data were extracted and quality assessed independently by two reviewers using the DEPICT-2 (Descriptive Elements of Pharmacist Intervention Characterization Tool) and the Crowe Critical Appraisal Tool (CCAT), respectively. Studies were grouped according to the clinical area into 5 sections: (1) pain control and opioid consumption; (2) venous thromboembolism (VTE); (3) surgery-related gastrointestinal complications; (4) postoperative medication management; and (5) total parenteral nutritional. RESULTS: Nineteen studies involving a total of 7,168 patients were included; most studies were conducted in gastrointestinal (n = 7) and orthopedics (n = 6) surgical units. Most included studies (n = 14) employed a multicomponent intervention including pharmaceutical care, education, guideline development, drug information services, and recommendations formulation. The processes of developing the implemented interventions and their structures were seldom reported. Positive impacts of pharmacist intervention on clinical outcomes included significant improvement in pain control and reductions in the incidence of VTE, surgery-related stress ulcer, nausea, and vomiting. There is inconsistency in the findings related to medication management (ie, achieving desired therapeutic ranges) and management of chronic conditions (hypertension and type 2 diabetes). CONCLUSION: Whilst there is some evidence of positive impacts of pharmacist intervention on clinical outcomes and optimizing drug therapy, this evidence is generally of low quality and insufficient volume. While this review suggests that pharmacists have essential roles in improving the care of patients undergoing surgery, more research with rigorous designs is required.

Application of behavioural theories, models, and frameworks in pharmacy practice research based on published evidence: a scoping review.

BACKGROUND: Pharmacy practice research often focuses on the design, implementation and evaluation of pharmacy services and interventions. The use of behavioural theory in intervention research allows understanding of interventions' mechanisms of action and are more likely to result in effective and sustained interventions. AIM: To collate, summarise and categorise the reported behavioural frameworks, models and theories used in pharmacy practice research. METHOD: PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science and EBSCO (CINAHL PLUS, British Education index, ERIC) were systematically searched to capture all pharmacy practice articles that had reported the use of behavioural frameworks, theories, or models since inception of the database. Results were filtered to include articles published in English in pharmacy practice journals. Full-text screening and data extraction were independently performed by two reviewers. A narrative synthesis of the data was adopted. Studies were reviewed for alignment to the UK Medical Research Council (MRC) framework to identify in which phase(s) of the research that the theory/model/framework had been employed. RESULTS: Fifty articles met the inclusion criteria; a trend indicating an increasing frequency of behavioural theory/frameworks/models within pharmacy practice research was identified; the most frequently reported were Theory of Planned Behaviour and Theoretical Domains Framework. Few studies provided explicit and comprehensive justification for adopting a specific theory/model/framework and description of how it underpinned the research was lacking. The majority were investigations exploring determinants of behaviours, or facilitators and barriers to implementing or delivering a wide range of pharmacy services and initiatives within a variety of clinical settings (aligned to Phase 1 UK MRC framework). CONCLUSION: This review serves as a useful resource for future researchers to inform their investigations. Greater emphasis to adopt a systematic approach in the reporting of the use of behavioural theories/models/frameworks will benefit pharmacy practice research and will support researchers in utilizing behavioural theories/models/framework in aspects of pharmacy practice research beyond intervention development.

Emergency pharmacy workforce views and experience related to the provision of pharmaceutical care during mass gathering events: the FIFA World Cup Qatar 2022™ experience.

Purpose: This study aimed to explore emergency pharmacy workforce perspectives and experiences in providing pharmaceutical care during mass gathering events (i.e., FIFA World Cup Qatar 2022™). Methods: A qualitative methodology was employed using focus groups discussions. Emergency pharmacists across Hamad Medical Corporation were invited to participate using a combination of purposive and snowball sampling. Focus groups were audio-recorded, transcribed verbatim, and validated. Inductive thematic analysis was undertaken to generate key themes and subthemes. Results: Four focus groups were conducted which included 21 participants and generated five major themes. Whilst participants had mixed opinions in relation to their preparedness to practice during the World Cup, they perceived their experience as successful and smooth. The primary perceived facilitators were management support, mobile medical units, and high public health awareness. The main highlighted barriers were related to staff insufficiency, medications availability, and cultural and language challenges. Participants recommended pharmacist's role identification in mass gatherings, development of pharmacy action plan, and offering simulation training and pharmacy-specific training. Conclusion: Despite the perceived barriers, pharmacists reported positive views in relation to their experience in providing pharmaceutical care during mass gatherings. Future research should focus on the development of theory-driven action framework for pharmacy departments to adopt during mass gatherings.

[This corrects the article DOI: 10.1371/journal.pone.0253588.].

Characteristics of the clinical pharmacists' interventions at the main general tertiary care hospital in Qatar.

Medication-related problems (MRPs) are prevalent throughout healthcare systems, whereby pharmacy-based interventions are pivotal to reducing occurrence. In the Middle East, including Qatar, the professional roles of pharmacists have been expanding to improve patient safety. This study aimed to characterize and analyze pharmacist-led interventions among hospitalized patients in the leading general hospital in Qatar. A retrospective analysis of pharmacist interventions in the internal medicine ward, critical care unit, and emergency department (ED) was conducted. Data were extracted from three periods of 1 month (March 1-31, 2018, July 15-August 15, 2018, and January 1-31, 2019). A descriptive type of analysis was undertaken. A total of 340 patients with 858 interventions were analyzed. The average age of the study participants was 51 years (SD ± 17.7). The study population was predominantly male (65%). The prevailing pharmacist intervention was adding drug therapy (27%), followed by medication discontinuation (18%) and dosage adjustments (16%). This pattern was maintained across all subpopulations, e.g., gender, age, and ward, except for the ED, where cessation of medication was the most frequent intervention (4%). The two pharmacological classes associated with most interventions were anti-infective and cardiovascular agents. Pharmacist interventions effectively identify, prevent, and resolve MRPs in general inpatient settings in Qatar.

Prevalence, contributing factors, and interventions to reduce medication errors in outpatient and ambulatory settings: a systematic review.

BACKGROUND: Medication errors are common events that compromise patient safety. Outpatient and ambulatory settings enhance access to healthcare which has been linked to favorable outcomes. While medication errors have been extensively researched in inpatient settings, there is dearth of literature from outpatient settings. AIM: To synthesize the peer-reviewed literature on the prevalence, nature, contributory factors, and interventions to minimize medication errors in outpatient and ambulatory settings. METHOD: A systematic review was conducted using Medline, Embase, CINAHL, and Google Scholar which were searched from 2011 to November 2021. Quality assessment was conducted using the quality assessment checklist for prevalence studies tool. Data related to contributory factors were synthesized according to Reason's accident causation model. RESULTS: Twenty-four articles were included in the review. Medication errors were common in outpatient and ambulatory settings (23-92% of prescribed drugs). Prescribing errors were the most common type of errors reported (up to 91% of the prescribed drugs, high variations in the data), with dosing errors being most prevalent (up to 41% of the prescribed drugs). Latent conditions, largely due to inadequate knowledge, were common contributory factors followed by active failures. The seven studies that discussed interventions were of poor quality and none used a randomized design. CONCLUSION: Medication errors (particularly prescribing errors and dosing errors) in outpatient settings are prevalent, although reported prevalence range is wide. Future research should be informed by behavioral theories and should use high quality designs. These interventions should encompass system-level strategies, multidisciplinary collaborations, effective integration of pharmacists, health information technology, and educational programs.

Prevalence and global trends of polypharmacy in patients with chronic liver disease: A systematic review and meta-analysis.

BACKGROUND: Despite its central role in drug metabolism, the exact prevalence estimates and factors affecting global trends of polypharmacy in patients with chronic liver disease (CLD) have remained unexamined. The aim of this systematic review and meta-analysis is to estimate the prevalence of polypharmacy in patients with CLD and to comprehensively synthesize the socio-demographic factors that drive this. METHODS: We conducted a comprehensive search of relevant databases (PubMed, EMBASE, Science citation index, Cochrane Database of Systematic Reviews, and database of abstracts of reviews of effectiveness) for studies published from inception to May 30, 2022 that reported on prevalence estimates of polypharmacy in patients with CLD. The risk of bias was conducted utilizing Loney criteria. The primary outcome was the pooled prevalence of polypharmacy in patients with CLD. We subsequently performed a systematic review and weighted meta-analysis to ascertain the exact pooled prevalence of polypharmacy among patients with CLD. RESULTS: We identified approximately 50 studies from the initial literature search, of which 7 (enrolling N = 521,435 patients) with CLD met the inclusion criteria; of these, 58.7% were male, with a mean age of 53.9 (SD ±â€…12.2) years. The overall pooled prevalence of polypharmacy among patients with CLD was 31% (95% confidence interval [CI]: 4%-66%, I2 = 100%, τ2 ≤ 0.001, P ≤ .0001). We found higher pooled prevalence estimates among patients aged 50 years and older compared to their younger cohorts (42%, [CI 10-77]; I2 = 100%, P = <.001 vs 21%, [CI 0-70]; I2 = 100%, P = <.001). CONCLUSION: In an examination of multiple community- and hospital-based databases of patients with CLD, we found a pooled prevalence estimate of polypharmacy of approximately 31%. This represents a case burden within the range reported in the general population and will likely respond to mitigation strategies employed thus far for patients in that population.

Disaster Preparedness Amongst Emergency Pharmacists for the FIFA World Cup Qatar 2022™: A Cross-Sectional Survey.

Purpose: The aim of this study is to assess the level of preparedness of pharmacists working in the emergency department at Hamad Medical Corporation (HMC) for any emergency disasters that may take place during the FIFA World Cup Qatar 2022™ by evaluating their awareness (A), attitude (A), and readiness (R). Methods: A cross-sectional quantitative observational study was conducted through a web-based survey. The survey was distributed among emergency pharmacists working in general hospitals under HMC. The questionnaire was composed of three major domains assessing awareness, attitude, readiness, as well as an additional domain to collect the participants' demographics. Student's t-test, analysis of variance, Pearson's correlation, and linear regression were used with an alpha level of 0.05. Results: Most pharmacists working in the emergency departments at HMC had high levels of awareness (76.9%), attitude (92%), and readiness (53.8%) for any emergency disasters that may occur during the FIFA World Cup 2022. Nonetheless, almost half of the respondents reported moderate level of readiness for emergency events. Pharmacists with >10 years' practice experience had significantly higher AAR score compared to those with <5 years' experience (P = 0.002). Significant direct positive correlations were found among the 3 AAR parameters (P < 0.05). Attitude was found to be a significant predictor of readiness (P < 0.05). A model composed of attitude and awareness could predict 12% of readiness score. Conclusion: Emergency pharmacists at HMC have high level of preparedness for any emergency disaster event during the World Cup. Future research should focus on the development of theory-based action framework for pharmacy departments during mass gathering events.

A prospective observational study to evaluate the safety of COVID-19 mRNA vaccines administered to Qatar Rehabilitation Institute patients.

BACKGROUND: The safety of the COVID-19 mRNA vaccine in the outpatient setting has been extensively studied; however, there need to be more reports that specifically assess their safety in the inpatient population. It is hence imperative to explore the adverse drug reaction (ADR) profile in this population and monitor the progression of these ADRs in a hospital setting. This provides a unique opportunity to closely observe patients to ensure no side effects go undiagnosed. This study aims to explore and quantify the incidence and severity of ADRs in patients who have received the COVID-19 vaccine during their stay in the rehabilitation facility. METHODS: This is a prospective observational study, which included adult patients admitted to the rehabilitation facility who were deemed eligible to receive the COVID-19 vaccine during their hospital stay. Data were collected by the investigators from June 2021 to May 2022 at 24 hours, 48 hours, and 7 days post-vaccination. A piloted data collection tool was utilized. RESULTS: Thirty-five patients met the inclusion criteria. Pain at the injection site was the most commonly reported local ADR, while headache was the most frequent systemic ADR. The majority of the reported ADRs were mild to moderate in nature, with only one severe reaction detected. Although no statistical significance was noted among the variables, common patterns were identified, such as a higher occurrence of fever at 24 hours after the second dose as opposed to the first dose. Close monitoring of the included study subjects did not reveal any unanticipated ADRs or an increase in ADRs susceptibility and severity compared to the general population. CONCLUSION: This study supports the initiation of vaccination campaigns in inpatient rehabilitation settings. This approach would offer the advantage of gaining full immunity and reducing the risk of contracting COVID-19 infection and complications once discharged.

Prevalence and global trends of polypharmacy in patients with chronic kidney disease: A systematic review and meta-analysis.

Background and objectives: Polypharmacy and chronic kidney disease (CKD) are becoming increasingly common due to an ageing population and the rise of multimorbidity. In line with the therapeutic guidelines, managing CKD and its complications necessitates prescribing multiple medications, which predisposes patients to polypharmacy. The aim of this systematic review and meta-analysis is to describe the prevalence of polypharmacy in patients with CKD and to explore the global trends of factors driving any apparent variability in prevalence estimates. Methods: PubMed, Scopus, the Cochrane Database of Systematic Reviews (CDSR), and Google Scholar were searched from 1999 to November 2021. Study selection, data extraction, and critical appraisal were conducted by two independent reviewers. The pooled prevalence of polypharmacy was estimated utilizing the random effects model using the default double arcsine transformation. Results: This review involved 14 studies comprising of 17 201 participants, a significant proportion of which were males (56.12%). The mean age of the review population was 61.96 (SD ± 11.51) years. The overall pooled prevalence of polypharmacy amongst patients with CKD was 69% (95% CI: 49%-86%) (I2 = 100%, p < 0.0001), with a proportionately higher prevalence in North America and Europe as compared to Asia. Conclusion: The results from this meta-analysis showed a high pooled prevalence estimates of polypharmacy amongst patient cohorts with CKD. The exact interventions that are likely to significantly mitigate its effect remain uncertain and will need exploration by future prospective and systematic studies.

Profile of tirzepatide in the management of type 2 diabetes mellitus: design, development, and place in therapy.

INTRODUCTION: Type 2 diabetes mellitus (T2DM) is one of the leading causes of morbidity and mortality. Peptide-based multi-targeting agonists represent a new paradigm in metabolic pharmacology as they manifest multiplexed pharmacological actions over mono-agonists. Tirzepatide is a novel dual glucose-dependent insulinotropic polypeptide receptor (GIPR) and glucagon-like peptide-1 receptor (GLP-1R) agonist that has been recently approved by the FDA. This review aims to summarize the available evidence on the discovery, pharmacology, pharmacokinetic, pharmacodynamic, efficacy, and safety of tirzepatide in the pharmacotherapy of T2DM. AREAS COVERED: We searched PubMed, Embase, and International Pharmaceutical Abstracts to identify relevant papers on tirzepatide use in T2DM. Clinical trial registries were also searched. EXPERT OPINION: Tirzepatide improves glycemic control compared to baseline, placebo, and active comparators. It is also associated with weight reduction and an improvement in some, but not all, dyslipidemia, cardiovascular risk, and nonalcoholic steatohepatitis (NASH) biomarkers. Tirzepatide has a favorable safety profile with a low risk of hypoglycemia; however, adverse events such as gastrointestinal reactions were frequently reported and sometimes even led to therapy discontinuation. Future research should focus on investigating the role of tirzepatide in obesity, NASH, and cardio-renal benefits. Real-world observational studies are also needed to assess rare and long-term adverse events.

The Economic Impact of Optimizing a COVID-19 Management Protocol in Pre-Existing Cardiovascular Disease Patients.

This study answers the question of whether the health care costs of managing COVID-19 in preexisting cardiovascular diseases (CVD) patients increased or decreased as a consequence of evidence-based efforts to optimize the initial COVID-19 management protocol in a CVD group of patients. A retrospective cohort study was conducted in preexisting CVD patients with COVID-19 in Hamad Medical Corporation, Qatar. From the health care perspective, only direct medical costs were considered, adjusted to their 2021 values. The impact of revising the protocol was a reduction in the overall costs in non-critically ill patients from QAR15,447 (USD 4243) to QAR4337 (USD 1191) per patient, with an economic benefit of QAR11,110 (USD 3051). In the critically ill patients, however, the cost increased from QAR202,094 (USD 55,505) to QAR292,856 (USD 80,433) per patient, with added cost of QAR90,762 (USD 24,928). Overall, regardless of critical care status, the optimization of the initial COVID-19 protocols in patients with preexisting CVD did not reduce overall health care costs, but increased it by QAR80,529 (USD 22,117) per patient.

Learning needs assessments in continuing professional development: A scoping review.

BACKGROUND: A rigorous learning needs assessment (LNA) is a crucial initial step in the Continuing Professional Development (CPD) process. This scoping review aimed to collate, summarize, and categorize the reported LNA approaches adopted to inform healthcare professional CPD and highlight the gaps for further research. METHOD: In August 2020, nine bibliographic databases were searched for studies conducted with any health professional grouping, reporting the utilized LNA to inform CPD activities. Two reviewers independently screened the articles for eligibility and charted the data. A descriptive analytical approach was employed to collate, summarize, and categorize the literature. RESULTS: 151 studies were included in the review; the majority adopted quantitative methods in the form of self-assessment surveys. Mixed-methods approaches were reported in only 35 studies. Descriptions of LNA development lacked detail of measures taken to enhance their rigor or robustness. DISCUSSION: These findings do not reflect recommendations offered by the CPD literature. Further investigations are required to evaluate more recently advocated LNA approaches and add to their limited evidence-base. Similarly, the existing support afforded to CPD developers warrants further study in order to identify the necessary resource, infrastructure and expertise essential to design and deliver effective CPD programs.

An umbrella review of systematic reviews on contributory factors to medication errors in health-care settings.

INTRODUCTION: Medication errors are common events that compromise patient safety and are prevalent in all health-care settings. This umbrella review aims to systematically evaluate the evidence on contributory factors to medication errors in health-care settings in terms of the nature of these factors, methodologies and theories used to identify and classify them, and the terminologies and definitions used to describe them. AREAS COVERED: Medline, Cumulative Index to Nursing and Allied Health Literature, Embase, and Google Scholar were searched from inception to March 2022. The data extraction form was derived from the Joanna Briggs Institute (JBI) Reviewers' Manual, and critical appraisal was conducted using the JBI quality assessment tool. A narrative approach to data synthesis was adopted. EXPERT OPINION: Twenty-seven systematic reviews were included, most of which focused on a specific health-care setting or clinical area. Decision-making mistakes such as non-consideration of patient risk factors most commonly led to error, followed by organizational and environmental factors (e.g. understaffing and distractions). Only 10 studies had a pre-specified methodology to classify contributory factors, among which the use of theory, specifically Reason's theory was commonly used. None of the reviews evaluated the effectiveness of interventions in preventing errors. The collated contributory factors identified in this umbrella review can inform holistic theory-based intervention development.

The determination of causality of drug induced liver injury in patients with COVID-19 clinical syndrome.

BACKGROUND: Drug induced liver injury (DILI) is a rising morbidity amongst patients with COVID-19 clinical syndrome. The updated RUCAM causality assessment scale is validated for use in the general population, but its utility for causality determination in cohorts of patients with COVID-19 and DILI remains uncertain. METHODS: This retrospective study was comprised of COVID-19 patients presenting with suspected DILI to the emergency department of Weill Cornell medicine-affiliated Hamad General Hospital, Doha, Qatar. All cases that met the inclusion criteria were comparatively adjudicated by two independent rating pairs (2 clinical pharmacist and 2 physicians) utilizing the updated RUCAM scale to assess the likelihood of DILI. RESULTS: A total of 72 patients (mean age 48.96 (SD ± 10.21) years) were examined for the determination of DILI causality. The majority had probability likelihood of "possible" or "probable" by the updated RUCAM scale. Azithromycin was the most commonly reported drug as a cause of DILI. The median R-ratio was 4.74 which correspond to a mixed liver injury phenotype. The overall Krippendorf's kappa was 0.52; with an intraclass correlation coefficient (ICC) of 0.79 (IQR 0.72-0.85). The proportion of exact pairwise agreement and disagreement between the rating pairs were 64.4%, kappa 0.269 (ICC 0.28 [0.18, 0.40]) and kappa 0.45 (ICC 0.43 [0.29-0.57]), respectively. CONCLUSION: In a cohort of patients with COVID-19 clinical syndrome, we found the updated RUCAM scale to be useful in establishing "possible" or "probable" DILI likelihood as evident by the respective kappa values; this results if validated by larger sample sized studies will extend the clinical application of this universal tool for adjudication of DILI.

What is polypharmacy in people living with HIV/AIDS? A systematic review.

Polypharmacy in people living with HIV/AIDS (PLWHA) is a rising morbidity that exacts hefty economic burden on health budgets in addition to other adverse clinical outcomes. Despite recent advances, uncertainty remains around its exact definition in PLWHA. In this systematic review and Meta-analysis, we explored relevant databases (PUBMED, EMBASE, CROI) for studies evaluating polypharmacy in PLWHA from January 2000 to August 2021 to ascertain the exact numerical threshold that defines this morbidity. Two independent reviewers extracted and reviewed relevant variables for analyses. The review included a total of 31 studies involving n = 53,347 participants with a mean age of 49.5 (SD ± 17.0) years. There was a total of 36 definitions, with 93.5% defining polypharmacy as the concomitant use of 5 or more medications. We found significant variation in the numerical definition of polypharmacy, with studies reporting it as "minor" (N = 3); "major" (N = 29); "severe" (N = 2); "excessive" (N = 1); and "higher" (N = 1). Most studies did not incorporate a duration (84%) in their definition and excluded ART medications (67.7%). A plurality of studies in PLWHA have established that polypharmacy in this cohort of patients is the intake of ≥ 5 medications (including both ART and non-ART). To standardize the approach to addressing this rising morbidity, we recommend incorporation of this definition into national and international PLWHA treatment guidelines.

Critical care tele-pharmacy services during COVID-19 pandemic: A qualitative exploration of healthcare practitioners' perceptions.

WHAT IS KNOWN AND OBJECTIVE: The scope of clinical pharmacy services has changed during COVID-19 pandemic with the view to mitigating both exposure and spread of the virus. The performance of novel pandemic-driven services such as tele-pharmacy has remained unexplored, until now. The aim of this study is to investigate the perceptions of healthcare providers of the impact of tele-pharmacy services provided in critical care units during COVID-19. METHODS: A qualitative study of semi-structured interviews conducted with healthcare practitioners who worked in COVID-19 intensive care units and remotely interacted with clinical pharmacists at the Weill Cornell-affiliated Hamad Medical Corporation, Doha, Qatar. Random sampling technique was employed to recruit participants, with the resultant interview guide piloted before commencement of data collection process. RESULTS AND DISCUSSION: From a total 129 and 200 physicians and nurses, respectively, 20 interviews were conducted with physicians (n = 15), and nurses (n = 5). From these interactions, a number of major themes emerged including: satisfactory understanding across clinical environment and personnel (physician and nurses) about remote clinical pharmacists' roles; additional robust feedback on the perception of the remote clinical pharmacy service; an understanding by 'frontline' health personnel on the discernible differences between remote and in-person coverage of clinical pharmacists; a reflection by both physicians and nurses on the novel challenges involved in the implementation of such pandemic-driven service; and solutions to overcome these challenges. WHAT IS NEW AND CONCLUSION: In this novel qualitative study of pandemic-driven tele-pharmacy service, we found a positive perception amongst healthcare practitioners towards this service; with residual challenges that will need further evaluation by large sampled sized surveys or mixed methods research.

A systematic review on the impact of pharmacist-provided services on patients' health outcomes in Arab countries.

WHAT IS KNOWN AND OBJECTIVE: The pharmacist's role has evolved dramatically over the last few decades and shows considerable impact globally. The aim of this systematic review was to describe the nature and extent of studies evaluating the impact of pharmacist-provided services on clinical, humanistic and economic outcomes in different healthcare settings across the Arab world. METHODS: A systematic literature search was conducted using the following databases from their inception until June 2020: Cochrane, Embase, MEDLINE, PubMed, ScienceDirect and Scopus. Reporting was done according to PRISMA guidelines, and the quality assessment utilized the Mixed Methods Appraisal Tool. RESULTS AND DISCUSSION: Thirty-five eligible studies were included in this review, the majority of which were randomized controlled trials (RCT) (n = 26) conducted in hospital settings (n = 26). Most of the studies involved patients with specific medical conditions (n = 29) and pharmacist's interventions involved mainly medication therapy management (n = 32), counselling and education (n = 29), and medication therapy recommendations (n = 12). Several studies showed a positive impact (i.e., a statistically and/or clinically significant difference in favour of pharmacist-provided care or intervention) of pharmacist-provided services on clinical (n = 28), humanistic (n = 6) and economic (n = 5) outcomes. Conversely, five studies showed neutral or mixed effect of pharmacist interventions on clinical and humanistic outcomes. WHAT IS NEW AND CONCLUSION: The findings of this systematic review demonstrate a positive impact of pharmacist-provided services on clinical, humanistic and economic outcomes across diverse settings in the Arab world. Most of the included studies evaluated clinical outcomes and were from hospital setting. Directed approaches are needed to advance pharmacy practice across various healthcare settings in the Arab world.

An investigation into the avoidability of drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome.

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rising morbidity amongst hospitalized patients. Whilst clinical protocols for the management of individual DRESS cases have been well established, determination of potential prevention of these cases by utilizing novel "avoidability" tools has remained unexplored. This retrospective study reviewed records of patients who presented to the emergency department of Weill Cornell Medicine-affiliated Hamad General Hospital, Doha Qatar with suspected DRESS syndrome. These cases were independently adjudicated (utilizing the RegiSCAR, and JSCAR tools) as DRESS-drug pairs by a team of two clinical pharmacists and two General Physicians. They were then rated for potential avoidability with the Liverpool adverse drug reactions avoidability tool (LAAT) by the same team of raters. A total of 16 patients satisfied RegiSCAR criteria for DRESS syndrome. The mean age of the study population was 41.5 years (SD ± 13.3). The study population was predominantly male (n = 12; [75%]). The median latent period from drug ingestion to clinical presentation was 14 days (interquartile range [IQR] 6.5, 29). The median RegiSCAR and J-SCAR scores were 6 (IQR 5, 6.8), 5 (IQR 4, 5.8) respectively. Utilizing the LAAT, about 60% of the DRESS syndrome-drug pairs were rated as "avoidable" ("probable" or "definite"). The overall Krippendorf's alpha with the LAAT was 0.81 (SE 0.10, CI 0.59-1.00); with an intraclass correlation coefficient (ICC) of 0.90 (CI 0.77, 0.96.). In a randomly selected cohort of DRESS syndrome-drug pairs, a significant proportion was potentially avoidable ("possibly" and "definitely") utilizing the LAAT. This will need validation by larger sample-sized prospective studies utilizing the updated LAAT proposed by this study.

Pharmacist-led educational interventions provided to healthcare providers to reduce medication errors: A systematic review and meta-analysis.

INTRODUCTION: Medication errors are avoidable events that can occur at any stage of the medication use process. They are widespread in healthcare systems and are linked to an increased risk of morbidity and mortality. Several strategies have been studied to reduce their occurrence including different types of pharmacy-based interventions. One of the main pharmacist-led interventions is educational programs, which seem to have promising benefits. OBJECTIVE: To describe and compare various pharmacist-led educational interventions delivered to healthcare providers and to evaluate their impact qualitatively and quantitatively on medication error rates. METHODS: A systematic review and meta-analysis was conducted through searching Cochrane Library, EBSCO, EMBASE, Medline and Google Scholar from inception to June 2020. Only interventional studies that reported medication error rate change after the intervention were included. Two independent authors worked through the data extraction and quality assessment using Crowe Critical Appraisal Tool (CCAT). Summary odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using a random-effects model for rates of medication errors. Research protocol is available in The International Prospective Register of Systematic Reviews (PROSPERO) under the registration number CRD42019116465. RESULTS: Twelve studies involving 115058 participants were included. The two main recipients of the educational interventions were nurses and resident physicians. Educational programs involved lectures, posters, practical teaching sessions, audit and feedback method and flash cards of high-risk abbreviations. All studies included educational sessions as part of their program, either alone or in combination with other approaches, and most studies used errors encountered before implementing the intervention to inform the content of these sessions. Educational programs led by a pharmacist were associated with significant reductions in the overall rate of medication errors occurrence (OR, 0.38; 95% CI, 0.22 to 0.65). CONCLUSION: Pharmacist-led educational interventions directed to healthcare providers are effective at reducing medication error rates. This review supports the implementation of pharmacist-led educational intervention aimed at reducing medication errors.
