Background: Limited knowledge exists on the association between polypharmacy among older patients diagnosed with cardiometabolic diseases and the risk of clinical outcomes and healthcare utilization.

Aim: This study aimed to estimate the impact of polypharmacy on clinical outcomes and healthcare utilization in older adults with cardiometabolic diseases.

Method: A retrospective cohort analysis was performed using data from the Beijing Municipal Medical Insurance Database. The study focused on polypharmacy prescribing patterns in community-dwelling adults 65 years and older with cardiometabolic diseases. Polypharmacy was defined as the use of five or more medications on the index date. The primary outcome included clinical outcomes, including hospitalizations and emergency department visits. The secondary outcome focuses on hospital utilization, specifically medication costs and length of stay.

Results: The study included a cohort of 405,608 patients. Among these, the most frequently used drug classes in the polypharmacy and non-polypharmacy groups were HMG-CoA reductase inhibitors and dihydropyridines, respectively. After adjustment for covariates, polypharmacy was not associated with an increased risk of hospitalization (odds ratio [OR] 1.09, 95% confidence interval [CI] 0.95-1.26, p = 0.23) or ED visits (OR 1.28, 95% CI 0.97-1.68, p = 0.08). Similarly, no significant association was found with an increase in inpatient medication costs ($2,620.5, 95% CI $2387.3-$2894.3, p = 0.97) or length of stay (3.98 days, 95% CI 3.68-4.30 days, p = 0.79). However, polypharmacy was associated with higher medication costs in outpatient settings ($73.07, 95% CI $72-$74, p < 0.05) and ED visits ($51.2, 95% CI $44.5-$59.1, p < 0.05).

Conclusion: Although polypharmacy is associated with increased healthcare costs in outpatient settings and ED visits, it does not significantly increase the risk of hospitalization or ED visits when properly managed.

Background: Establishing effective pharmacovigilance systems globally is challenging due to the need for comprehensive epidemiological data on pharmacovigilance-related events, particularly in countries at different stages of development.

Aim: This study aimed to determine magnitude and drivers of change in the global and regional burden of pharmacovigilance-related events from 1990 to 2019, analyzing variations between age groups and sex, providing data support for policymakers to adjust their pharmacovigilance policies.

Method: Pharmacovigilance-related events were defined as Adverse Effects of Medical Treatment (AEMT) and Drug Use Disorders (DUD) in the Global Burden of Diseases, Injuries, and Risk Factors Study 2019. Time trend analysis utilized joinpoint regression, age-period-cohort model, and decomposition method. Disease burden was measured in incidence, deaths, and disability-adjusted life years (DALYs).

Results: The global burden of pharmacovigilance-related events remained high, driven predominantly by population growth. Children and older adults were identified as particularly susceptible groups. Across various regions and periods of the socio-demographic index (SDI), the risk of death from AEMT showed a decreasing trend. In contrast, the incidence of AEMT and both the incidence and death rates from DUD showed a stable or worsening trend. Significant regional disparities in the burden of these diseases were noted between different SDI levels.

Conclusion: The study underscores the critical need for robust pharmacovigilance systems worldwide. The observed trends in the burden of pharmacovigilance-related events offer a clear direction for countries to refine and strengthen their pharmacovigilance policies and practices.

Background: Medication errors significantly compromise patient safety in emergency departments. Although previous studies have investigated the prevalence of these errors in this setting, results have varied widely.

Aim: The aim was to report pooled data on the prevalence and severity of medication errors in emergency departments, as well as the proportion of patients affected by these errors.

Method: Systematic searches were conducted in Embase, PubMed, and the Cochrane Library from database inception until June 2023. Studies provided numerical data on medication errors within emergency departments were eligible for inclusion. Random-effects meta-analysis was employed to pool the prevalence of medication errors, the proportion of patients experiencing these errors, and the error severity levels. Heterogeneity among studies was assessed using the I² statistic and Cochran's Q test.

Results: Twenty-four studies met the inclusion criteria. The meta-analysis gave a pooled prevalence of medication errors in emergency departments of 22.6% (95% Confidence Interval [CI] 19.2-25.9%, I² = 99.9%, p < 0.001). The estimated proportion of patients experiencing medication errors was 36.3% (95% CI 28.3-44.3%, I² = 99.8%, p < 0.001). Of these errors, 42.6% (95% CI 5.0-80.1%) were potentially harmful but not life-threatening, while no-harm errors accounted for 57.3% (95% CI 14.1-100.0%).

Conclusion: The prevalence of medication errors, particularly those potentially harmful, underscores potential safety issues in emergency departments. It is imperative to develop and implement effective interventions aimed at reducing medication errors and enhancing patient safety in this setting.

Background: The antihypertensive effects of angiotensin II receptor blockers (ARBs) are well recognized. However, conventional meta-analyses have reported inconsistent results on their efficacy and safety.

Aim: This study aimed to evaluate the efficacy and safety of six ARBs (losartan, valsartan, irbesartan, telmisartan, candesartan, and olmesartan) commonly used to treat hypertension, using a network meta-analysis.

Method: We retrieved randomized controlled trials on hypertension treatment using ARBs from the PubMed, Embase, Cochrane Library, CNKI, and Wanfang databases. The efficacy outcomes included absolute changes in office systolic and diastolic blood pressure from baseline, and 24-h ambulatory blood pressure. Safety outcomes were assessed by the total number of adverse events (AEs) during treatment. We conducted the network meta-analysis using the 'bugsnet' and 'gemtc' packages in R.

Results: A total of 193 studies were included. Olmesartan had the highest surface under the cumulative ranking in reducing office systolic (91.4%) and diastolic blood pressure (87.2%). Candesartan has the highest ranking in lowering 24 h ambulatory systolic blood pressure (95.4%), while telmisartan reduced 24 h ambulatory diastolic blood pressure (83.4%). Olmesartan also ranked highest in safety (70.8%).

Conclusion: Valsartan and losartan were less effective in lowering blood pressure than other drugs, with no significant differences. Olmesartan and telmisartan were associated with fewer AEs than losartan, although the incidence of adverse events was similar between the other blockers. Olmesartan and telmisartan demonstrated the best balance of antihypertensive efficacy and minimal adverse events. More research is needed to confirm whether telmisartan and olmesartan are optimal choices for controlling blood pressure in patients.

Background: Worldwide, depression is known to contribute significantly to the global burden of disease. Considering pharmacists are among the most approachable healthcare providers, they are well-placed to assist people with depression achieve positive treatment outcomes.

Aim: The primary aim was to examine the evidence regarding pharmacists' roles in interventions, outcomes, and barriers to implementation within depression care globally, with the secondary aim focusing on the Arab region.

Method: A scoping review was conducted according to the PRISMA-ScR extension guidelines and the Joanna Briggs Institute framework, using Scopus, Cochrane, ProQuest, and Medline databases for studies worldwide and within the Arab region (22 Arab-league countries). Article selection, along with data extraction, analysis, and narrative synthesis were performed independently by two reviewers. Discrepancies were resolved by consensus.

Results: Forty studies reporting various roles and services provided by pharmacists in depression management were included. Most articles (24) described studies on pharmacist-led specific/single interventions/management strategies, and 16 described studies in which pharmacists provided comprehensive or team-based services. The majority of studies reported positive impact on patient outcomes. In accordance with the secondary aim, only three studies assessed various pharmacists' services for people with depression in the Arab region. Barriers to effective depression-related care included time constraints and training needs.

Conclusion: This scoping review supports the expanding role of pharmacists in depression management. The interventions, impact, challenges, and research gaps identified serve as preliminary evidence for advocating for an expanded pharmacists' scope of practice in mental health, both globally and in the Arab region.

Background: Patient satisfaction has been positively associated with adherence which is expected to impact outcomes. Although vital for successful implementation of biosimilar medicines, little is known about the patient perspective of transition.

Aim: The aim of this study was to investigate clinical outcomes and patient experience of transitioning between reference adalimumab and a biosimilar (SB5).

Method: iBaSS is a phase IV single-centre, prospective, randomised, single-blind, cross-over study in adult subjects with Crohn's disease. Participants, stable on adalimumab before consent, received 24 weeks of treatment with both reference adalimumab and SB5. The primary outcome was the proportion of patients maintaining baseline clinical status throughout each treatment period, with patients' perspective of disease control and treatment satisfaction assessed as secondary outcomes.

Results: A total of 112 participants, representative of the heterogeneous patient populations encountered in routine clinical practice, were enrolled. A similar proportion of participants maintained baseline clinical status through each treatment period: 81.8% with reference adalimumab and 79.5% with SB5. Patient reported outcomes (IBD-Control questionnaire (SB5: 15.5; reference adalimumab 15) and TSQM), adverse events and therapeutic drug monitoring remained consistent through both treatment periods, although a higher median injection pain VAS score was noted with SB5 (53/100 versus 6/100 with reference adalimumab). The number of switches undertaken in the study did not impact serum drug concentration or immunogenicity.

Conclusion: This study, mimicking real world adalimumab transition, demonstrates that patients undertaking brand transition can be expected to have consistent clinical and satisfaction outcomes.

Background: Camrelizumab combined with rivoceranib has been proven effective for treating unresectable hepatocellular carcinoma (uHCC). However, their higher prices than sorafenib could impose a substantial economic burden on patients.

Aim: This study aimed to evaluate the relative cost-effectiveness of the combination of camrelizumab and rivoceranib versus sorafenib as first-line therapy for patients with uHCC from the perspective of the US and Chinese payers.

Method: Using data from the CARES-310 trial, a partitioned survival model (PSM) was developed, considering the perspectives of the US and Chinese payers. The model employed a 15-year time horizon and a biweekly cycle. Direct medical costs and utility data were collected from previous studies and open-access databases. Primary outcomes included quality-adjusted life years (QALYs) and the incremental cost-effectiveness ratio (ICER). Price simulations, sensitivity analyses, and subgroup analyses were conducted.

Results: The ICER for the US and China was $122,388.62/QALY and $30,410.56/QALY, respectively, falling below the willingness-to-pay (WTP) thresholds of $150,000/QALY for the US and $35,898.87/QALY for China. Price simulations indicated the cost-effectiveness of camrelizumab plus rivoceranib when the price of camrelizumab (200 mg) remained below $6275.19 in the US and $558.09 in China. The primary determinant of cost-effectiveness in both regions was the cost of camrelizumab.

Conclusion: The combination of camrelizumab and rivoceranib is a cost-effective first-line therapy for uHCC in both the US and China. Lowering their prices could significantly influence their cost-effectiveness and accessibility to patients. These findings will guide clinicians in treating uHCC and help decision-makers formulate value-based drug pricing strategies.

Background: Pharmacy professionals, given their health expertise, can play a role in enhancing health education within their communities and among patients. The potential of the pharmacy workforce to enhance health education among primary school children is underexplored.

Aim: This study aimed to investigate the perspectives of pharmacy staff on the provision of education regarding self-care and treatment of minor ailments to primary school-aged children and to identify roles that pharmacists could play in this regard.

Method: Qualitative semi-structured interviews were conducted online with frontline pharmacy staff in the UK who had patient facing roles with primary school-aged children and parents. Interviews were audio-recorded and transcribed verbatim. Thematic data analysis was applied to the transcripts.

Results: A total of 17 participants were recruited. Participants included 12 pharmacists, two pharmacy technicians and three pharmacy dispensers. All participants worked within community, hospital or primary care facilities. Five themes emerged from the data analysis: sources of health knowledge accessed by children and parents; a perceived lack of knowledge regarding self-care and treatments for minor ailments among children and parents; a perceived positive impact of education on self-care; barriers to health education; and the potential role of pharmacy staff in self-care education in schools.

Conclusion: Pharmacy staff recognise the value of integrating health education into primary school curricula. A collaborative approach with educational institutions could bridge the gap in knowledge regarding self-care and treatment of minor ailments, and could empower children and reduce unnecessary use of healthcare resources.

Background: Vancomycin trough concentration is closely associated with clinical efficacy and toxicity. Predicting vancomycin trough concentrations in pediatric patients is challenging due to significant inter-individual variability and rapid physiological changes during maturation.

Aim: This study aimed to develop a machine learning model to predict vancomycin trough concentrations and determine optimal dosing regimens for pediatric patients < 4 years of age using ML algorithms.

Method: A single-center retrospective observational study was conducted from January 2017 to March 2020. Pediatric patients who received intravenous vancomycin and underwent therapeutic drug monitoring were enrolled. Seven ML models [linear regression, gradient boosted decision trees, support vector machine, decision tree, random forest, Bagging, and extreme gradient boosting (XGBoost)] were developed using 31 variables. Performance metrics including R-squared (R²), mean square error (MSE), root mean square error (RMSE), and mean absolute error (MAE) were compared, and important features were ranked.

Results: The study included 120 eligible trough concentration measurements from 112 patients. Of these, 84 measurements were used for training and 36 for testing. Among the seven algorithms tested, XGBoost showed the best performance, with a low prediction error and high goodness of fit (MAE = 2.55, RMSE = 4.13, MSE = 17.12, and R² = 0.59). Blood urea nitrogen, serum creatinine, and creatinine clearance rate were identified as the most important predictors of vancomycin trough concentration.

Conclusion: An XGBoost ML model was developed to predict vancomycin trough concentrations and aid in drug treatment predictions as a decision-support technology.

Background: Although various aspects of cisplatin resistance have been studied, the impact of genetic variations still needs to be explored.

Aim: This study aimed to investigate the impact of cisplatin on meningiomas using a two-sample Mendelian randomization (MR) approach, employing genetic variants associated with cisplatin use as instrumental variables.

Method: We conducted a two-sample MR analysis using genome-wide association study (GWAS) data. Instrumental variables were derived from single-nucleotide polymorphisms (SNPs) associated with meningioma to estimate the causal relationship with cisplatin resistance. Sensitivity analyses were performed to confirm the findings.

Results: Genetic predisposition to meningioma significantly increased the risk of cisplatin resistance (odds ratio (OR): 1.63; 95% confidence interval (CI) 1.44-1.85, P < 0.05). Sensitivity analyses supported the causal link.

Conclusion: This MR study suggests that genetic predisposition to meningioma increases susceptibility to cisplatin resistance. Further research is needed to uncover the mechanisms behind these causal effects.
