Clinical pharmacists' involvement in carbapenem antibiotics management at Wenzhou Integrated Hospital.

BACKGROUND: Carbapenem antibiotics are a pivotal solution for severe infections, particularly in hospital settings. The emergence of carbapenem-resistant bacteria owing to the irrational and extensive use of carbapenems underscores the need for meticulous management and rational use. Clinical pharmacists, with their specialized training and extensive knowledge, play a substantial role in ensuring the judicious use of carbapenem. This study aimed to elucidate the patterns of carbapenem use and shed light on the integral role played by clinical pharmacists in managing and promoting the rational use of carbapenem antibiotics at Wenzhou Integrated Traditional Chinese and Western Medicine Hospital. AIM: To analyze carbapenem use patterns in our hospital and role of clinical pharmacists in managing and promoting their rational use. METHODS: We performed a retrospective analysis of carbapenem use at our hospital between January 2019 and December 2021. Several key indicators, including the drug utilization index, defined daily doses (DDDs), proportion of antimicrobial drug costs to total hospitalization expenses, antibiotic utilization density, and utilization rates in different clinical departments were comprehensively analyzed. RESULTS: Between 2019 and 2021, there was a consistent decline in the consumption and sales of imipenem-cilastatin sodium, meropenem (0.3 g), and meropenem (0.5 g). Conversely, the DDDs of imipenem-cilastatin sodium for injection increased in 2020 and 2021 vs 2019, with a B/A value of 0.67, indicating a relatively higher drug cost. The DDDs of meropenem for injection (0.3 g) exhibited an overall upward trend, indicating an increasing clinical preference. However, the B/A values for 2020 and 2021 were both > 1, suggesting a relatively lower drug cost. The DDDs of meropenem for injection (0.5 g) demonstrated a progressive increase annually and consistently ranked first, indicating a high clinical preference with a B/A value of 1, signifying good alignment between economic and social benefits. CONCLUSION: Carbapenem use in our hospital was generally reasonable with a downward trend in consumption and sales over time. Clinical pharmacists play a pivotal role in promoting appropriate use of carbapenems.

Evaluation of prescribing patterns using WHO core drug use indicators in a pediatric hospital of Kabul Afghanistan: A prospective cross-sectional study.

Background: The global issue of irrational drug use, particularly concerning pediatric patients, is a significant concern. Notably, there has been a lack of studies assessing rational drug prescribing for pediatric patients within Afghanistan's healthcare system. This investigation aimed to address this gap by examining drug prescribing patterns at the Indira Gandhi Pediatric Health Institute (IPHI) in Kabul, Afghanistan. Methods: A prospective cross-sectional analysis was conducted to evaluate the prevailing drug prescribing practices at the outpatient department of IPHI in Kabul, Afghanistan. A systematic random sampling method was employed to select 600 outpatient prescriptions from the institute, following the World Health Organization (WHO) guidelines for investigating drug utilization in healthcare facilities. Results: The average age of patients was 4 years, and the average number of drugs per prescription was 2.9. Notably, 84% of prescriptions included one or more antibiotics, surpassing the WHO standard of <30%. Furthermore, 67% of the prescribed drugs were listed on Afghanistan's national essential drugs list (EDL), falling below the standard value of 100%. Only 35.1% of the prescribed drugs were in generic form, also lower than the recommended 100%. Moreover, 5.7% of all prescriptions included injections, the ideal value is <20%. The most frequently prescribed drug groups were anti-microbials (25.7%), followed by non-steroidal anti-inflammatory drugs (NSAIDs), (21.4%), gastrointestinal drugs (17.3%), and vitamins (7.8%). Conclusion: The study's findings indicate that, on average, a higher number of drugs were prescribed per patient visit at IPHI compared to recommended standards. Additionally, there was a lower utilization of generic drugs and drugs from Afghanistan's national essential drugs list (EDL), with an over-prescription of antibiotics.

Association of arbitrary prescribing behavior to costly drug expenditures: a pharmacoeconomic study in primary care.

BACKGROUND: We aimed to examine the cost-related prescribing performance of primary care physicians who had a higher versus lower tendency of arbitrary prescribing. METHODS: In this cross-sectional study, we evaluated the prescriptions of primary care physicians in Istanbul, collected with 3:1 systematic sampling. We determined higher versus lower arbitrary prescribing by the physician's degree of writing the solo diagnosis of "Z00- General examination without diagnosis/complaint": those for whom such prescriptions constituted >5% were classified as Group A and those with them at <0.5% as Group B. We compared these two groups by the total and disease-specific drug costs per prescription they produced for 10 frequently encountered indications. RESULTS: The median cost of disease-specific medication for all diagnoses in Group A and Group B, except anemia, was equal. In upper respiratory tract infections (URTIs), hypertension, anemia, diabetes, and conjunctivitis, the mean prescription costs of Group A were significantly higher than those of Group B (P < .001, P < .001, P = .009, P = .007, and P < .001, respectively), whereas disease-specific drug costs per prescription were similar (P > .05 in all diagnoses). In myalgia, Group A had lower cost per prescription (P < .001) and higher analgesic costs per prescription (P < .001) compared to those in Group B. We found significantly higher disease-specific drug cost share in Group B for URTIs (antibiotic), gastroesophageal reflux disease (gastric acid-suppressant), hypertension (antihypertensive), anemia (iron preparations), diabetes (antidiabetic), depression (antidepressant), and conjunctivitis (corticosteroid) than those in Group A (P < .001 for each). CONCLUSIONS: Our study showed that physicians who had a higher tendency of prescribing for no clear indication are also more likely to produce costly prescriptions.

Rational Drug and Antibiotic Use Status, E-Health Literacy in Syrian Immigrants and Related Factors: A Cross-Sectional Study.

Rational drug use is a pivotal concept linked with morbidity and mortality. Immigration plays a significant role as a determinant affecting individuals' health-related attitudes, behaviors, and the pursuit of health services. Within this context, the study was initiated to assess the factors influencing health literacy and rational drug use among Syrian immigrants in Istanbul. A cross-sectional study was undertaken on 542 Syrian adults utilizing a three-part questionnaire encompassing sociodemographics, rational drug use, and the e-health literacy scale (eHEALS). With an average age of 39.19 ± 13.10 years, a majority of participants believed medications should solely be doctor-prescribed (97%) and opposed keeping antibiotics at home (93.7%). Yet, 62.5% thought excessive herbal medicine use was harmless. The mean eHEALS score stood at 20.57 ± 7.26, and factors like age, marital status, income, and duration of stay in Turkey influenced e-health literacy. Associations were seen between low e-health literacy and being female, being older, having a lower education level, and regular medication use. Syrian immigrants displayed proper knowledge concerning antibiotics yet exhibited gaps in their understanding of general drug usage, treatment adherence, and herbal medicines. Approximately 80.3% had limited health literacy, pointing to the need for targeted interventions for enhanced health and societal assimilation.

Enhancing Primary Care for Nursing Home Patients with an Artificial Intelligence-Aided Rational Drug Use Web Assistant.

Polypharmacy can result in drug-drug interactions, severe side-effects, drug-disease interactions, inappropriate medication use in the elderly, and escalating costs. This study aims to evaluate nursing home residents' medication regimens using a rational drug use web assistant developed by researchers to mitigate unnecessary medication usage. This analytical, cross-sectional study included data from nursing home residents recently recorded in a training family health center. Sociodemographic information, medical conditions, and prescribed medications of all patients in the nursing home (n = 99) were documented. Medications were assessed using an artificial intelligence-aided rational drug use web assistant. Instances of inappropriate drug use and calculations of contraindicated drug costs were also recorded. The study revealed that 88.9% (n = 88) of patients experienced polypharmacy, with a mean value of 6.96 ± 2.94 drugs per patient. Potential risky drug-drug interactions were present in 89.9% (n = 89) of patients, contraindicated drug-drug interactions in 20.2% (n = 20), and potentially inappropriate drug use in 86.9% (n = 86). Plans to discontinue 83 medications were estimated to reduce total direct medication costs by 9.1% per month. After the assessment with the rational drug use web assistant, the number of drugs that patients needed to use and polypharmacy decreased significantly. This study concludes that the rational drug use web assistant application, which is more cost-effective than the traditional manual method, assisted by artificial intelligence, and integrated into healthcare services, may offer substantial benefits to family physicians and their geriatric patients.

Assessment of prescription completeness and drug use pattern using WHO prescribing indicators in private community pharmacies in Addis Ababa: a cross-sectional study.

BACKGROUND: Healthcare systems in both developing and developed countries were not free from prescription errors. One of the effects of prescription errors is irrational prescribing. According to the estimation of the World Health Organization (WHO), greater than 50% of medicines are prescribed and dispensed irrationally. On the other hand, research on drug use patterns in the private healthcare sector is scarce. This study aimed to assess prescription Completeness and Drug use Pattern using WHO prescribing indicators in Private Community Pharmacies in Lemi-Kura sub-city. METHODS: Based on the WHO prescribing indicators, a retrospective cross-sectional technique was employed to examine the completeness and drug-prescription patterns. The study was conducted from April to May 2021. Prescriptions, kept for 1 year that was prescribed from March 2020 to March 2021, by private healthcare sectors, were analyzed. A systematic random sampling technique was employed to select prescriptions obtained from private health facilities. Data were analyzed using SPSS® version 26.0 software. RESULTS: Of a total of 1000 prescriptions, 1770 drugs were prescribed and the average number of drugs per prescription was 1.77. Prescriptions for two drugs account for 38% of these, while prescriptions for three drugs account for 15%. Age, sex, and card number were written on 99.0%, 99.2%, and 41.8% of prescriptions, respectively. The patient's name was written on every prescription. Even though the availability of other therapeutic information on the prescription made it appear greater, only 44.2% of prescriptions included the dosage form of medications. The generic name was used for the majority of the medications (67.8%). Furthermore, assuming that each prescription was for a single patient, 71% of patients received antibiotics, and 2% received injectable medicines. The National List of Essential Medicines-Ethiopia was used in 99.6% of the prescriptions. CONCLUSIONS: On the basis of the finding of this study, the prescribing and prescription completeness indicator showed deviation from the standard recommended by WHO. This situation could be critical since a similar pattern is reported from public healthcare sectors, which might imply the extent of non-adherence to WHO core drug use standards. Consequently, it could play a considerable role in increasing prescription errors in Ethiopia. Hence, in-service training for prescribers should be provided to improve adherence to basic prescription writing.

Facilitators and barriers of the rational drug use hospital program in Thailand

The Thailand Ministry of Public Health has started a rational drug use (RDU) policy, which includes multifaceted strategies as well as the RDU hospital program to tackle irrational drug use. Objective: To investigate facilitators and barriers related to the CIPP model of the RDU hospital program in Thailand. Methods: This is a qualitative study. Data were collected through semi-structured interviews with regional policymakers who were members of the executive board for RDU management in the 10th health region. The interviews were conducted via telephone using a topic guide informed by the CIPP framework and reviewed for content validity by the research team. Data were transcribed, and thematically analyzed. Results: Fifteen pharmaceutical policymakers were interviewed. The main facilitators related to context, input, and process were the national policy on RDU, RDU awareness/practices among health professionals, particularly prescribers, and multidisciplinary teamwork under the organization’s leadership to use data feedback to improve the program. The main barriers related to context, input, and process were a lack of policy advocacy at the regional and provincial levels, doctor-related reasons such as medicolegal concerns, and a lack of multidisciplinary teamwork. For the product theme, participants were very satisfied and perceived positive impacts at both the individual and organizational levels, such as increased RDU awareness in patients and multidisciplinary teams, as well as RDU prescription. However, negative impacts, such as tensions surrounding professional responsibility and accountability, have been observed. (AU)

Quality of Drug Prescribing and Dispensing Practices in Primary Healthcare Centres in an Urban Local Government Area in Nigeria.

BACKGROUND: Irrational drug use remains a major issue in developing countries; hence this study used the World Health Organization and the International Network for the Rational Use of Drugs (WHO/INRUD) core drug indicators to assess the quality of prescribing and dispensing practices in Primary Health Centres (PHCs) in Obio-Akpor Local Government Area (LGA) in Nigeria. METHODS: This descriptive cross-sectional study which covered 10 PHCs in Obio-Akpor LGA comprised a review of prescription records and a survey of patients and prescribers. A systematic random sample approach was used to retrieve 1300 prescriptions from August to October 2021 to evaluate prescribing indicators while direct observation of 325 consecutive patient encounters in the PHCs was used to evaluate the patient-care indicators. Twenty-three prescribers in the 10 PHCs who were available and willing to participate in the study, completed the self-administered questionnaire for assessment of the factors affecting prescribing practices. Descriptive and inferential analyses were done using the Statistical Package for the Social Sciences and p-values d" 0.05 were considered statistically significant. RESULTS: From the 1300 retrieved prescriptions, a total of 3805 medications were prescribed for the 1300 encounters giving 2.9 (± 0.5) as the mean medications prescribed per encounter. Prescriptions in generic forms were 69.9% and 75.6% of drugs prescribed were from the Nigeria essential medicine list for PHCs. Encounters with antibiotics and injectables included in the prescriptions were 62.6% and 22.3% respectively. Antimalarial, antihypertensive, and antidiabetic medications were prescribed in 43.8 %, 9.6 %, and 1.7 % of the cases, respectively. Most (91.6 %) of the recommended drugs were dispensed, 98.2% of the drugs dispensed were appropriately labelled, and 95.5 % of the patients had an adequate understanding of their drug doses. The pharmacy stocked 88.7% of the key medications, and all PHCs had a copy of the EDL. CONCLUSION: There was evidence of irrational drug use practices in PHCs in Obio-Akpor LGA. This calls for the implementation of periodic training for PHC workers, the promotion of effective monitoring and adherence to the policy of rational drug use in PHCs.

CONTEXTE: L'utilisation irrationnelle des médicaments reste un problème majeur dans les pays en développement ; c'est pourquoi cette étude a utilisé les indicateurs de base de l'Organisation mondiale de la santé et du Réseau international pour l'utilisation rationnelle des médicaments (OMS/INRUD) pour évaluer la qualité des pratiques de prescription et de délivrance dans les centres de soins de santé primaires (SSP) de la zone de gouvernement local (LGA) d'Obio-Akpor au Nigéria. MÉTHODES: Cette étude transversale descriptive, qui couvre 10 centres de santé primaires dans la zone de gouvernement local d'Obio-Akpor, comprend un examen des dossiers de prescription et une enquête auprès des patients et des prescripteurs. Une approche d'échantillonnage aléatoire systématique a été utilisée pour récupérer 1300 ordonnances d'août à octobre 2021 afin d'évaluer les indicateurs de prescription, tandis que l'observation directe de 325 rencontres consécutives avec des patients dans les SSP a été utilisée pour évaluer les indicateurs de soins aux patients. Vingt-trois prescripteurs des 10 SSP, disponibles et désireux de participer à l'étude, ont rempli le questionnaire auto-administré pour évaluer les facteurs affectant les pratiques de prescription. Les analyses descriptives et inférentielles ont été réalisées à l'aide du logiciel Statistical Package for the Social Sciences et les valeurs p d" 0,05 ont été considérées comme statistiquement significatives. RÉSULTATS: Sur les 1300 ordonnances récupérées, 3805 médicaments ont été prescrits au total, ce qui donne une moyenne de 2,9 (± 0,5) médicaments prescrits par consultation. Les prescriptions sous forme générique représentaient 69,9 % et 75,6 % des médicaments prescrits figuraient sur la liste des médicaments essentiels du Nigeria pour les SSP. Les rencontres avec des antibiotiques et des injectables inclus dans les prescriptions étaient respectivement de 62,6 % et 22,3 %. Des antipaludéens, des antihypertenseurs et des antidiabétiques ont été prescrits dans 43,8 %, 9,6 % et 1,7 % des cas, respectivement. La plupart (91,6 %) des médicaments recommandés ont été délivrés, 98,2% des médicaments délivrés étaient correctement étiquetés et 95,5 % des patients comprenaient bien les doses de médicaments. La pharmacie stockait 88,7 % des principaux médicaments et tous les SSP disposaient d'une copie de la liste de médicaments d'urgence. CONCLUSION: Il existe des preuves de pratiques irrationnelles d'utilisation des médicaments dans les SSP de l'AGL d'Obio-Akpor. Ceci appelle à la mise en œuvre d'une formation périodique pour les travailleurs des SSP, à la promotion d'un suivi efficace et à l'adhésion à la politique d'utilisation rationnelle des médicaments dans les SSP.

Prospective prescription review system correlated with more rational PPI medication use, better clinical outcomes and reduced PPI costs: experience from a retrospective cohort study.

INTRODUCTION: Proton pump inhibitor (PPI) abuse poses an overwhelming threat to the allocation of medical resources and places a heavy burden on global medical expenses. In this study, we put forward our prospective prescription review system and evaluated the effects of this system on clinical outcomes, rational medication use and costs related to PPIs. METHODS: A retrospective cohort study was conducted in which the included patients were divided into a preintervention group (2019.10-2020.09) and a postintervention group (2020.10-2021.09). To reduce the bias of patients' baseline characteristics, the propensity score matching (PSM) method was employed. The primary endpoints were the incidence of stress ulcers (SUs), the improvement and cure rates of gastrointestinal haemorrhage, the defined daily dose (DDD), the drug utilization index (DUI) and the DDD/100 patient-days. The secondary endpoints included the types of unreasonable medication orders for PPIs, the PPI utilization rate and PPI costs. RESULTS: A total of 53,870 patients were included to evaluate the secondary endpoints, and 46,922 patients were paired by PSM and assessed to evaluate the primary endpoints. The number of PPIs used and PPI costs were significantly lower in the postintervention group than in the preintervention group (P < 0.001). The rationality evaluation results showed that the frequency of PPI use and the number of drug interactions were significantly higher in the preintervention group than in the postintervention group (P < 0.01). The proportion of patients taking oral PPIs was significantly increased in the postintervention group (29.30% vs. 34.56%, p < 0.01). For the utilization of PPIs both for prevention and treatment, the DUI and DDD/100 patient-days were substantially decreased in the postintervention group (P < 0.001 and P < 0.05, respectively). The incidence of SUs in the postintervention group was 44.95%, and that in the preintervention group was 51.93% (p < 0.05). CONCLUSION: The implementation of the prospective prescription review system on rational PPI use correlated with reduced PPI costs, more rational PPI medication use and better clinical outcomes, and this system is worthy of long-term implementation for further improvement of rational drug use.

A survey of chloroquine use for prevention and treatment of COVID-19 in Nigeria.

Background: Rampant chloroquine/hydroxychloroquine poisoning in Nigerian hospitals following suggestions of its possible efficacy in the treatment and prevention of the newly emerged COVID-19 disease informed this survey. Objectives: The aim of this study was to assess the knowledge, attitude and perception of the Nigerian populace on the use of chloroquine in the COVID-19 pandemic. Methods: This cross-sectional study was done by administering an electronic questionnaire created using Google Docs, through social media cascade methods including the WhatsApp application software to capture data on chloroquine use between April 20 and June 20, 2020. Results: Six hundred and twenty-eight people responded to the questionnaire (response rate 99.2%, mean age 41.05 ± 12.3) from the six geopolitical zones in Nigeria with 556 (88.5%) having tertiary level education. Only 21 (3.3%) of the respondents took chloroquine for treatment or prevention. Respondents from the North-west geopolitical zones used chloroquine 5.8 (95% CI: 1.55, 21.52, p=0.02) more times than other zones while the age group 20-29 were 8.8 times more likely to use chloroquine than any other age group (95% CI: 3.53, 21.70, p = 0.00). Female respondents were 2.3 times more likely to use chloroquine than the males (OR 2.26 95% CI: 0.90-5.68; p=0.08) and those in the income bracket of N75,000-99,000, 2.5 times more than other income groups. Conclusion: Young adults, North-western geopolitical zone, and female gender should be target groups for education on rational chloroquine use. The danger of chloroquine overdose should be communicated to the general population in Nigeria.

Development and Application of a Reference Manual for Diagnosis and Rational Use of Antimicrobial Agents for Outpatient Primary Care (Digestive System Part): A Delphi Study.

Purpose: To establish a concise and easy-to-understand reference manual for outpatient primary care providers, promoting correct diagnosis of digestive system diseases and rational antimicrobial use. Methods: The establishment of the manual encompassed two processes: the development of a draft manual and the validation of the manual. The development process was based on a literature review and expert discussion. The manual comprises portions for disease diagnosis and rationality of antimicrobial use. The validation process employed a two-round Delphi technique, collecting consensus through paper-based or mail-based communications. The response of the Delphi group was assessed by the level of authority and commitment of the panelists and the degree of agreement among them. Furthermore, the manual was preliminarily applied among primary care physicians. Results: A total of 29 panelists completed the Delphi working process. They were authoritative in their professional fields with authority coefficients of 0.813 and 0.818 for the two portions of the manual, respectively. The level of commitment of the panelists was measured by response rates, which were 100.00% and 96.67% for Round 1 and 2. After two rounds, a consensus was achieved with the consensus rates for the two portions of the manual being greater than 65% and 70%, respectively. Kendall W-tests had P-values < 0.001 in both rounds. This reference manual provides 200 diagnostic indicators for 29 common digestive diseases and recommendations for the rational use of antimicrobial agents for 13 categories of digestive diseases. The primary care physicians who used the reference manual reported high satisfaction and frequent usage. Conclusion: Based on a collective consensus of professionals, a reference manual has been established, to provide a concise and easy-to-understand guide specifically for physicians and pharmacists in outpatient primary care. It could facilitate rapid learning to improve the accuracy of diagnosis and treatment for digestive disorders.

Using intersectionality to study gender and antimicrobial resistance in low- and middle-income countries.

Different sexes and genders experience differentiated risks of acquiring infections, including drug-resistant infections, and of becoming ill. Different genders also have different health-seeking behaviours that shape their likelihood of having access to and appropriately using and administering antimicrobials. Consequently, they are distinctly affected by antimicrobial resistance (AMR). As such, it is crucial to incorporate perspectives on sex and gender in the study of both AMR and antimicrobial use in order to present a full picture of AMR's drivers and impact. An intersectional approach to understanding gender and AMR can display how gender and other components 'intersect' to shape the experiences of individuals and groups affected by AMR. However, there are insufficient data on the burden of AMR disaggregated by gender and other socio-economic characteristics, and where available, it is fragmented. For example, to date, the best estimate of the global burden of bacterial AMR published in The Lancet does not consider gender or other social stratifiers in its analysis. To address this evidence gap, we undertook a scoping review to examine how sex and gender compounded by other axes of marginalization influence one's vulnerability and exposure to AMR as well as one's access to and use of antimicrobials. We undertook a gendered analysis of AMR, using intersectionality as a concept to help us understand the multiple and overlapping ways in which different people experience exposure vulnerability to AMR. This approach is crucial in informing a more nuanced view of the burden and drivers of AMR. The intersectional gender lens should be taken into account in AMR surveillance, antimicrobial stewardship, infection prevention and control and public and professional awareness efforts, both donor and government funded, as well as national and international policies and programmes tackling AMR such as through national action plans.

Evaluation of the proper use of medication available over the counter by subsistence and emerging farmers in Mbombela Municipality, South Africa.

South Africa has two types of animal farming systems, being the commercial industry and subsistence farming in more rural areas, with commercial farmers having more access to veterinary services. To cater for the absence of sufficient veterinary service, the country allows farmers to access certain over the counter medications (stock remedies), as a way to assist them to farm sustainably and profitably. However, with any drug use, their true benefits are only realized following correct use. The aim of this study was to describe and assess the adequacy of the current use of veterinary drugs by rural-based farmers. A scheduled structured questionnaire with close-ended questions and direct observation was employed. The most important finding was the absence of proper training in the area, with 82.9% not receiving any training related to livestock production or use/handling of stock remedies, highlighting the urgent need for proper training. Of interest, a large proportion of the farmers (57.5%) left the care of their animals to herders. Concerns were also noted in the application of withholding periods, transport of medication, disposal of medication, calculation of drug doses, correct route of administration and carcass disposal with no difference in response between farmers receiving training and those who didn't. These finding not only indicates the importance of farmer training, but shows that for such training to be effective, information should not only cover farming activities but must include primary animal health care and an understanding of information contained in package leaflets. It would also be important to ensure that herdsmen are also included in such training initiatives as they are the primary careers of the animals.

Effects of plateau hypoxia on population pharmacokinetics and pharmacodynamics of metformin in patients with Type 2 diabetes. / 高原低氧对2åž‹ç³–å°¿ç— æ‚£è€ äºŒç”²åŒèƒç¾¤ä½“è¯åŠ¨å­¦å’Œè¯æ•ˆå­¦çš„å½±å“ï¼ˆè‹±æ–‡ï¼‰.

OBJECTIVES: Metformin is the basic drug for treating diabetes, and the plateau hypoxic environment is an important factor affecting the pharmacokinetics of metformin, but there have been no reports of metformin pharmacokinetic parameters in patients with diabetes mellitus type 2 (T2DM) in the high-altitude hypoxic environment. This study aims to investigate the effect of the hypoxic environment on the pharmacokinetics and assess the efficacy and safety of metformin administration in patients with Type 2 diabetes mellitus (T2DM). METHODS: A total of 85 patients with T2DM taking metformin tablets in the plateau group (n=32, altitude: 1 500 m) and control group (n=53, altitude: 3 800 m) were enrolled according to the inclusion and exclusion criteria, and 172 blood samples were collected in the plateau group and the control Group. A ultra-performance liquid chromatography/tandem mass spectrometry (UFLC-MS/MS) method was established to determine the blood concentration of metformin, and Phoenix NLME software was used to establish a model of pharmacokinetics of metformin in the Chinese T2DM population. The efficacy and serious adverse effects of metformin were compared between the 2 groups. RESULTS: The population pharmacokinetic modeling results showed that plateau hypoxia and age were the main covariates for model building, and the pharmacokinetic parameters were significantly different between the plateau and control groups (all P<0.05), including distribution volume (V), clearance (CL), elimination rate constant (Ke), half-life(T1/2), area under the curve (AUC), time to reach maximum concentration (Tmax). Compared with the control group, AUC was increased by 23.5%, Tmax and T1/2 were prolonged by 35.8% and 11.7%, respectively, and CL was decreased by 31.9% in the plateau group. The pharmacodynamic results showed that the hypoglycaemic effect of T2DM patients in the plateau group was similar to that in the control group, the concentration of lactic acid was higher in the plateau group than that in the control group, and the risk of lactic acidosis was increased after taking metformin in the plateau population. CONCLUSIONS: Metformin metabolism is slowed down in T2DM patients in the hypoxic environment of the plateau; the glucose-lowering effect of the plateau is similar, and the attainment rate is low, the possibility of having serious adverse effects of lactic acidosis is higher in T2DM patients on the plateau than on the control one. It is probably suggested that patients with T2DM on the plateau can achieve glucose lowering effect by extending the interval between medication doses and enhancing medication education to improve patient compliance.

The effect of education on self-care agency and rational drug use of patients with COPD.

OBJECTIVE: This study examined the effects of education given to patients diagnosed with the COPD on self-care agency and rational drug use. METHODS: This study has a pretest-posttest quasi-experimental design. Participants were divided into two groups, those who received training with the COPD Guide booklet (n = 40) and routine clinical care (n = 43). RESULTS: As a result of the study found a statistically significant difference between the self-care agency and rational drug use scale post-test mean scores of the patients in the intervention and control group in favor of the intervention group (p < 0.01). CONCLUSION: Education on COPD management increased patients' self-care agency and their information, attitudes, and behaviors regarding rational drug use. PRACTICE IMPLICATIONS: Clinicians can integrate a COPD Guide into routine care for patients with COPD.

Private sector antimalarial sales a decade after "test and treat": A cross-sectional study of drug shop clients in rural Uganda.

Background: The World Health Organization has promoted "test and treat" guidelines for malaria since 2010, recommending all suspected malaria cases be confirmed with a parasitological test, typically a rapid diagnostic test (RDT), prior to treatment with antimalarial medications. However, many fevers at private drug shops in Uganda continue to be treated presumptively as malaria without diagnostic testing. Methods: The purpose of this study was to document private sector malaria case management in rural Uganda through a cross-sectional survey of drug shop clients in Bugoye sub-county. Drug shop vendors (n = 46) recorded information about sales interactions with clients reporting fever or requesting antimalarials and collected capillary blood samples from clients who purchased medications without an RDT. We estimated the proportion of clients who purchased an RDT, adhered to the RDT result, and received antimalarials without having laboratory-confirmed malaria. Results: Most drug shops were unlicensed (96%) and sold RDTs (98%). Of 934 clients with suspected malaria who visited study drug shops during the data collection period, only 25% bought an RDT. Since some clients reported previous RDTs from the public sector, 40% of clients were aware of their malaria status at the drug shop. Among those with negative tests, 36% still purchased antimalarials. Sixty-five percent of clients who purchased an antimalarial without an RDT subsequently tested negative. Conclusions: Despite national guidelines, drug shop clients who purchase antimalarials from drug shops in Bugoye are often not tested to confirm a malaria diagnosis prior to treatment. Most clients treated presumptively with antimalarials did not have malaria. Interventions are needed to improve malaria case management and rational drug use in the private sector.

Effect analysis of multi-department cooperation in improving etiological submission rates before antibiotic treatment.

Increased bacterial drug resistance has become a serious global public health problem. The application of antibiotics involves various clinical departments, and the rational application of antibiotics is the key to improving their efficacy. To provide a basis for further improving the etiological submission rate and standardizing the rational use of antibiotics, this article discusses the intervention effect of multi-department cooperation in improving the etiological submission rate before antibiotic treatment. A total of 87 607 patients were divided into a control group (n = 45 890) and an intervention group (n = 41 717) according to whether multi-department cooperation management was implemented. The intervention group involved the patients hospitalized from August to December 2021, while the control group involved the patients hospitalized from August to December 2020. The submission rates of the two groups; the rates before antibiotic treatment at the unrestricted use level, the restricted use level, and the special use level in departments; and the timing of submission were compared and analysed. The overall differences in the etiological submission rates before antibiotic treatment at the unrestricted use level (20.70% vs 55.98%), the restricted use level (38.23% vs 66.58%), and the special use level (84.92% vs 93.14%) were statistically significant before and after intervention (P < .05). At a more specific level, the etiological submission rates of different departments before antibiotic treatment at the unrestricted use level, the restricted use level, and the special use level were improved, but the special activities of multi-department cooperation management did not improve the submission timing significantly. Multi-department cooperation can effectively improve the etiological submission rates before antimicrobial treatment, but it is necessary to improve measures for specific departments to improve long-term management and incentive and restraint mechanisms.

Prevalence of Potential Drug-Drug Interactions Among Hypertensive Pregnant Women Admitted to a Tertiary Care Hospital.

AIMS AND OBJECTIVES: The aim is to determine the frequency of potential drug-drug interactions (pDDIs) and to analyze the clinically relevant drug interactions among hypertensive pregnant women. MATERIALS AND METHODS: This was an observational, cross-sectional study conducted at a tertiary care hospital. The prescriptions of the hypertensive pregnant women admitted to the hospital from June 2021 to December 2021 were analyzed for potential drug-drug interactions using the database from Lexicomp ® Solutions android mobile application version 7.5.4 (Wolters Kluwer, The Netherlands). RESULTS: A total of 127 patients were evaluated during the study period of 6 months, of which 70 (55.12%) had pDDIs. The total number of pDDIs was 85, of which 70 (82.35 %) were clinically relevant interactions with the majority of them having moderate severity (81.17%) followed by minor severity (17.65%) and major severity (1.18%). The most frequently interacting pDDIs were between Labetalol and Lornoxicam (42.35%), followed by Labetalol and Diclofenac (22.35%). CONCLUSION: This study highlights the high prevalence of potential drug interactions among hypertensive pregnant women and the need for rational drug use and strict vigilance in their monitoring.

Traditional medicine users in a treated chronic disease population: a cross-sectional study in Indonesia.

BACKGROUND: Traditional medicine (TM) is commonly used as a treatment in Indonesia. This raises the need for an analysis of its potential development and irrational use. Therefore, we analyze the proportion of TM users among chronic disease patients and its associated characteristics to optimize the use of TM in Indonesia. METHODS: A cross-sectional study of treated adult chronic disease patients was conducted using the fifth Indonesian Family Life Survey (IFLS-5) database. Descriptive analysis was used to identify the proportion of TM users, while a multivariate logistic regression was used to analyze their characteristics. RESULTS: This study included 4901 subjects and identified 27.1% as TM users. The highest TM use was in subjects with cancer (43.9%), liver issues (38.3%), cholesterol issues (34.3%), diabetes (33.6%), and stroke (31.7%). Characteristics associated with TM users were a perception of one's current health as unhealthy (OR 2.59, 95% CI 1.76-3.81), low medication adherence (OR 2.49, 95% CI 2.17-2.85), age above 65 years (OR 2.17, 95% CI 1.63-2.90), having higher education (OR 1.64, 95% CI 1.17-2.29), and residence outside of Java (OR 1.27, 95% CI 1.11-1.45). CONCLUSIONS: Low medication adherence among TM users highlights the potentially irrational use of treatment in chronic diseases. Nevertheless, the longstanding use of TM users indicates the potential for its development. Further studies and interventions are needed to optimize TM use in Indonesia.

The effect of illness perception levels of liver transplant patients receiving immunosuppressive therapy on their rational drug use levels.

Objective: Since 50% of drug use all over the world is used other than rational drug use, rational drug use, which is associated with the perception of the disease, is important for the course of the disease. This study aimed to determine the effect of disease perception levels on rational drug use in liver transplant patients receiving immunosuppressive therapy. Methods: This descriptive and cross-sectional study was conducted with patients who came to the outpatient clinic for control between May-September 2022 with the participation of patients who underwent liver transplantation and followed up in a liver transplant institute in eastern Turkey. In the collection of the study data, "sociodemographic information form" prepared by the researchers, "Brief Illness Perception Questionnaire", and "Rational Drug Use Scale" were employed. Results: In this study conducted with 206 patients, the mean age of patients with liver transplantation was 48.66 ± 9.4 years, 59.7% were male, 80.1% were married, and 33.5% were high school graduates. It was determined that the disease perception levels and rational drug use levels of the patients who underwent liver transplantation were moderate. It was also determined that as the education levels of the liver transplant patients increased, their levels of illness perception and rational drug use also statistically significantly increased (p < 0.05). It was found that there was a significant and moderate relationship between illness perception and rational drug use, and that as their level of illness perception increased, their level of rational drug use also increased (r:0.622, p < 0.05). It was observed that the disease perception level explained 38.7% of the change in rational drug use (R2:387, p < 0.05). Conclusions: In the study, it was observed that high illness perception levels of liver transplant patients increased their levels of rational drug use. It is important to raise the awareness of patients in order for them to cope with illnesses and to have a high level of illness perception.
