OBJECTIVE: The criteria for the use of proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) more restrictive than those approved were established in Catalonia by the Health System (CatSalut) to improve their efficiency, with different LDL-C values from which to start treatment according to risk factors. The aim of the study is to analyse adherence to these criteria and results.
METHODS: A retrospective study of patients treated with PCSK9i at Vall d\'Hebron University Hospital between 2016 and 2021 was performed using data from the Registry of Patients and Treatments and medical records. The degree of agreement with the CatSalut criteria, LDL-C-responders (decrease ≥30%), cardiovascular events and discontinuations were analysed.
RESULTS: A total of 193 patients treated with PCSK9i were followed for a median of 27 months (IQR 23). The median age was 61 (IQR 15); 62.7% were men. Seventy percent of the patients had non-familial hypercholesterolemia. Treatment was for secondary prevention of cardiovascular disease in 82.4% of cases. The median LDL-C decreased from 139 (IQR 52) to 59 (IQR 45) mg/dL. The percentage of LDL-C reduction was 61.0% (IQR 30). In 72.5% of patients, all CatSalut criteria for starting treatment were met. The rate of responders was 85.4%. During follow-up, 19 patients (9.8%) had a cardiovascular event, and 15 (7.7%) discontinued treatment, in two cases due to toxicity.
CONCLUSIONS: PCSK9i were used according to CatSalut criteria in three out of four cases. In this high-risk population, incidence of cardiovascular events was similar to that in clinical trials.

OBJECTIVE: To evaluate the impact of the pandemic on the consumption of antidepressive agents in Central Portugal.
METHODS: To estimate the causal effect of the pandemic an interrupted time series analysis was conducted. Data of antidepressant drugs monthly dispensed in community pharmacies between Jan-2010 and Dec-2021 were provided by the regional Health Administration. Anti-Parkinson dopaminergic agents and statins, theoretically not influenced by COVID-19 pandemics, were used as comparator series. The number of packages was converted into defined daily doses and presented as defined daily doses/1000 inhabitants/day. A Bayesian structural time-series model with CausalImpact on R/RStudio was used to predict the counterfactual. Analyses with different geographical granularity (9 sub-regions and 78 municipalities) were performed.
RESULTS: When compared to counterfactual, regional consumption non-significantly increased after the pandemic declaration, with a relative effect of + 1.30% [95%CI -1.6%:4.2%]. When increasing the granularity, differences appeared between sub-region with significant increases in Baixo Mondego + 6.5% [1.4%:11.0%], Guarda + 4.4% [1.1%:7.7%] or Cova da Beira + 4.1% [0.17%:8.3%], but non-significant variation in the remaining 6 sub-regions. Differences are more obvious at municipality level, ranging from increases of + 37.00% [32.00%:42.00%] to decreases of -11.00% [-17.00%:-4.20%]. Relative impact positively correlated with percentage of elderly in the municipality (r = 0.301; p = 0.007), and negatively with population density (r=-0.243; p = 0.032). No other predicting variables were found.
CONCLUSIONS: Antidepressant consumption suffered very slight variations at regional level after the COVID-19 pandemic declaration. Analysis with higher granularity allowed identifying municipalities with higher impact (increase or decrease). The absence of clear association patterns suggests other causal hypotheses of the differences.

UNASSIGNED: In immunosuppression after transplantation, several multi-drug approaches are used, involving calcineurin inhibitors (CNI: tacrolimus-TAC or cyclosporine-CsA), antimetabolites (antiMs), mammalian target of rapamycin inhibitors (mTORis), and corticosteroids. However, data on immunosuppressive therapy by organ and its space-time variability are lacking.
UNASSIGNED: An Italian multicentre observational cohort study was conducted using health information systems. Patients with incident transplant during 2009-2019 and resident in four regions (Veneto, Lombardy, Lazio, and Sardinia) were enrolled. The post-transplant immunosuppressive regimen was evaluated by organ, region, and year.
UNASSIGNED: The most dispensed regimen was triple-drug therapy for the kidneys [tacrolimus (TAC) + antiM + corticosteroids = 41.5%] and heart [cyclosporin  + antiM + corticosteroids = 36.6%] and double-drug therapy for liver recipients (TAC + corticosteroids = 35.4%). Several differences between regions and years emerged with regard to agents and the number of drugs used.
UNASSIGNED: A high heterogeneity in immunosuppressive therapy post-transplant was found. Further studies are needed in order to investigate the reasons for this variability and to evaluate the risk-benefit profile of treatment schemes adopted in clinical practice.

OBJECTIVE: The growing number of antidiabetics has broadened therapeutic options, leading to heterogeneity in prescribing patterns. Studies identifying antidiabetics modification patterns are lacking in Saudi Arabia. Therefore, the aim of this study is to describe modification patterns in Saudi patients.
METHODS: Patients ≥ 18 years old with at least one antidiabetic between 2016 and 2022 were included. Follow-up started from the earliest to the last prescription.Two modification types were evaluated: \"add-on,\" prescribing new antidiabetics within a treatment episode, and \"switching\", starting a new treatment episode after the preceding ends. Descriptive statistics were used to characterize patients and estimate events proportions.
RESULTS: Of 122,291 patients, 47.2 % had treatment interruption or modification, totaling 303,781 events. Interruptions accounted for 54 %, add-on for 11 %, and switching for 35 %. The median time to first event was 159 days. The most add-on included dipeptidyl peptidase-4 inhibitor (DPP-4) inhibitors to biguanide and sulfonylurea (8 %), and sulfonylurea to biguanide (8 %). Among 106,405 switching events, 23 % shifted from dual to monotherapy and 17 % from monotherapy to dual therapy.
CONCLUSIONS: Nearly half of patients experienced modifications or interruptions, with notable shifts between monotherapies and dual therapies. These findings highlight the evolving landscape of treatment patterns in Saudi Arabia and guide future research and decision-making.

BACKGROUND: Antimicrobial stewardship is an important action plan for curbing the rising trend of antimicrobial resistance (AMR). Surveillance of antimicrobial use and consumption is needed as baseline data and for monitoring the impact of antimicrobial stewardship interventions. The survey was done to understand the burden of AMR, in view of establishing an antimicrobial stewardship program in our hospital.
METHODS: A point prevalence survey (PPS) of antimicrobial use and consumption was conducted on all inpatients admitted before 8.00 am on the days of the survey using a standardized questionnaire. The collected data were entered online into the Global PPS web-based application (www.global-pps.com), for analysis.
RESULTS: Of the 178 patients admitted during the survey period, 50.6% were on one or more antimicrobial agents. All the patients in adult intensive care units were on antibiotics (100%), followed by neonatal intensive care units (83.3%), with the least being adult medical wards (39.4%). Beta-lactam antibiotics were the most frequently prescribed antimicrobial for various infections, especially skin and soft tissue infections, 41.3%, which were the most common diagnoses treated with antibiotics. The infection was mostly community-acquired (81.6%), of which 94.9% were treated empirically. There was no written guideline in existence.
CONCLUSIONS: The present study revealed a poor prescribing habit because of a high rate of empirical treatment. The need for antimicrobial stewardship cannot be overemphasized as it will help streamline and improve the prescribing pattern.

BACKGROUND: Affective disorders impose a significant burden on public health due to their high prevalence and associated suffering. This study addresses gaps in current literature and clinical practice by providing insights into medication usage trends, which can inform treatment strategies and optimize patient care. The study aims to investigate drug utilization patterns, particularly focusing on defined daily dose/1000/day, among individuals attending a psychiatric outpatient department of a tertiary care hospital.
METHODS: This cross-sectional, prospective drug utilization study included 600 affective disorder patients aged 18 years and above. The study period spanned 12 months, from March 2021 to February 2022. Data on demographics, diagnosis, treatment, and counseling were collected and analyzed using descriptive statistics.
RESULTS:  Among the 600 patients analyzed, bipolar mood disorder was the most prevalent (239 patients, 39.83%), followed by depressive disorder (208 patients, 34.67%). Triple therapy was the most common prescription regimen, accounting for 308 encounters (51.33%). The average number of drugs per encounter was 3.75 ± 1.01. A combination of psychotherapy and medication counseling sessions was provided to 594 patients or their relatives, representing 99% of the total encounters.
CONCLUSIONS: The study highlights the prevalent use of triple therapy in managing affective disorders, especially bipolar mood disorder and mania disorder. Effective utilization of essential drug lists and comprehensive patient counseling underscores the importance of holistic care in psychiatric outpatient settings.
CONCLUSIONS:  Given the high prevalence of triple therapy, further research into the efficacy and safety of this treatment approach is warranted. Additionally, continued emphasis on patient education and counseling can enhance treatment adherence and overall outcomes in individuals with affective disorders.

OBJECTIVE: This study aimed to evaluate the knowledge, attitude, and practice toward iron chelating agents (ICAs) in Iranian thalassemia major patients.
METHODS: A total of 101 patients with thalassemia major were involved in this cross-sectional survey. A deep medication review was done, and participants\' knowledge, attitude, and practice were evaluated by a validated instrument based on a 20-scoring system.
RESULTS: Statistical analyses showed 52 patients (51.5%) had a poor knowledge level (scores < 10) about their medications, 37 (36.6%) had a moderate level (scores 10-15), and 12 (11.9%) had a satisfactory level (scores > 15). Seventy-seven (76.2%) patients have positive beliefs regarding the dependence of their current health status on taking iron chelators, and 63 (62.4%) believed that they would become very ill without taking medication. The results also showed that the mean practice score in patients who received deferoxamine was 5.81 ± 3.50; in the patients who received deferiprone and those who received deferasirox, the mean scores were 7.36 ± 5.15 and 14.94 ± 4.14. Also, the knowledge and practice level had a direct linear correlation based on the regression analyses (P < 0.001).
CONCLUSIONS: In conclusion, results of the present research suggests that the patients\' knowledge about the administration, adverse events, and necessity of ICAs was not satisfactory. Improving the knowledge of thalassemia patients toward their medicines through educational interventions is highly recommended to improve their practice level.

UNASSIGNED: To compare statin utilization and ischemic heart disease (IHD) mortality trends in Lithuania and Sweden and to assess correlations between the total utilization of statins and IHD mortality.
UNASSIGNED: An ecological study assessing time trends in statin utilization (DDDs per 1000 inhabitants per day; DDD/TID) and IHD mortality in Lithuania and Sweden between 2000 and 2020. Statin utilization data in Lithuania were wholesale trade data, and Swedish data were drugs dispensed at pharmacies. IHD mortality data were extracted from national databases as rates per 100 000 inhabitants. Associations between statin utilization and IHD mortality in Lithuania and Sweden were examined using Spearman\'s rank and Pearson\'s correlation coefficients, respectively.
UNASSIGNED: Statin utilization increased from 16.8 to 135.8 DDD/TID in Sweden and from 0.2 to 61.8 DDD/TID in Lithuania between 2000 and 2020. Medium intensity was the most common statin dosage in Lithuania, while Sweden used more high intensity than moderate-intensity statins from 2017. IHD mortality in Lithuania remained high between 2000 and 2020 (from 359.1 to 508.8 deaths per 100 000 population), while it decreased markedly in Sweden (from 226.87 to 88.7 deaths per 100 000 population). IHD mortality and statin utilization were inversely correlated in Sweden (r = -0.993, P < 0.001), while a positive correlation was found in Lithuania (rs = 0.871, P < 0.001).
UNASSIGNED: Despite the growing statin utilization in both countries, Lithuania recorded a slight increase in IHD mortality rates unlike the situation in Sweden. This indicates room for improvement in the management of modifiable cardiovascular risk factors in Lithuania including how statins are prescribed and used in clinical practice.

UNASSIGNED: This study aimed to evaluate racial disparities in medication use and associated factors among pregnant women receiving prenatal care at Brazilian Unified Health System primary care health units in the northeast region.
UNASSIGNED: A total of 1058 pregnant women in the NISAMI Cohort were interviewed between June 2012 and February 2014. Medicines used during pregnancy were classified according to the Anatomical Therapeutic Chemical (ATC) classification system and ANVISA pregnancy risk categories. Prevalence ratios (crude and adjusted) and 95% confidence intervals (CIs) were estimated using Poisson regression with robust error variance. All analyses were stratified by race (Asian, black, brown/mixed, Brazilian indigenous, and white).
UNASSIGNED: Approximately 84% of the pregnant women used at least one medication, with a lower proportion among white women. The most reported medications were antianemic preparations (71.08%; 95% CI 68.27-73.72%), analgesics (21.74%; 95% CI 19.36-24.32%), and drugs for functional gastrointestinal disorders (18.81%; 95% CI 16.57-21.28%). Approximately 29% of women took potentially risky medications during pregnancy, with a higher prevalence among Asian and white women. Factors associated with medication use during pregnancy include a greater number of prenatal consultations, higher education levels, health problems, and smoking. In addition, maternal age above 25 years, smoking status, and two or more previous pregnancies were associated with potentially risky medication use during pregnancy.
UNASSIGNED: A high prevalence of medication use during pregnancy was found; however, this prevalence was lower among white women. Nonetheless, black and brown women used antianemic preparations less frequently. This finding suggests that race is a factor of inequity in prenatal care, demanding public policies to mitigate it.

BACKGROUND: Antibiotic consumption is a driver for the increase of antimicrobial resistance. The objective of this study is to analyze variations in antibiotic consumption and its appropriate use in Brazil from 2014 to 2019.
METHODS: We conducted a time series study using the surveillance information system database (SNGPC) from the Brazilian Health Regulatory Agency. Antimicrobials sold in retail pharmacies were evaluated. All antimicrobials recorded for systemic use identified by the active ingredient were eligible. Compounded products and formulations for topic use (dermatological, gynecological, and eye/ear treatments) were excluded. The number of defined daily doses (DDDs)/1,000 inhabitants/day for each antibiotic was attributed. The number of DDDs per 1,000 inhabitants per day (DDIs) was used as a proxy for consumption. Results were stratified by regions and the average annual percentage change in the whole period studied was estimated. We used the WHO Access, Watch, and Reserve (AWaRe) framework to categorize antimicrobial drugs.
RESULTS: An overall increase of 30% in consumption from 2014 to 2019 was observed in all Brazilian regions. Amoxicillin, azithromycin and cephalexin were the antimicrobials more consumed, with the Southeast region responsible for more than 50% of the antibiotic utilization. Among all antimicrobials analyzed 45.0% were classified as watch group in all Brazilian regions.
CONCLUSIONS: We observed a significant increase in antibiotics consumption from 2014 to 2019 in Brazil restricted to the Northeast and Central West regions. Almost half of the antibiotics consumed in Brazil were classified as watch group, highlighting the importance to promote rational use in this country.
