Drug Use Evaluation of Tenofovir/Lamivudine/Dolutegravir (TLD) Fixed-Dose Combination for Initiation and Transition Among HIV-Infected Individuals Attending Lumame Primary Hospital, North West Ethiopia.

Background: A key strategy for quality improvement is drug use evaluation, which looks at the safe, appropriate use of medication principles. Tenofovir/Lamivudine/Dolutegravir (TLD-FDC) usage has not yet been sufficiently examined in published literature. The purpose of this study was to assess how TLD were used by HIV-positive patients Using WHO drug use evaluation standards in Lumame Primary Hospital, North West Ethiopia. Methods: Using WHO drug use evaluation standards, a retrospective study design was used to evaluate the appropriateness of TLD use. Systematic random sampling was utilized to gather patient medical records containing TLD. Accordingly, 100 records that met the inclusion criteria were selected and reviewed between April 1 and 15, 2021. Five criteria, namely, indication, dose, contraindication, drug interaction, and TLD safety monitoring were used to evaluate the appropriateness of TLD utilization. Results: 80% of patients were transited to TLD from other regimens. The median time on TLD was found to be 13 months with 9 months to 18 months IQR. The latest CD4 count as well as CD4 count at the initiation or transition of TLD was not done for 75% and 89% of the patients, respectively. 3/4 (75%) of the patients were found to have a scheduled medication refill history. TLD dosing, indications, and contraindications were found to be 100% appropriate. No, TLD safety monitoring tests were done for 21% of the patients in this study. However, viral load, liver/kidney function, and serum creatinine tests were done for 77% (95% CI: 74%-79%), 5% (95% CI: 2%-8%), and 14% (95% CI: 11%-17%) of the patients, respectively. More over, In 93% (95% CI: 91%-95%) of the patients, the TLD interaction was appropriate; in 7%, it was not. All recording, documenting, and reporting technologies were available and used efficiently, except for the Electronic Dispensing Tool. Conclusion: Generally, good adherence to national and WHO guidelines was obtained regarding dose, indication, and contraindications. However, improvement in safety monitoring tests and CPT utilization is recommended. Drug interactions satisfied the majority of the criteria's threshold, while certain standards were not followed.

Establishment and application of drug utilization evaluation applying the weighted TOPSIS method: A study based on real-world data of tislelizumab.

BACKGROUND: How to comprehensively evaluate the rationality of drug use is a challenging issue. OBJECTIVE: To establish the evaluation index of the effective use of tislelizumab, so as to ensure its higher rationality and normalization in clinical application. METHODS: Based on the indications, drug instructions, and relevant guidelines of the National Basic Medical Insurance Restriction Catalogue, a retrospective analysis and evaluation of 286 cases of using tislelizumab injection in our hospital from January to December 2022 were conducted using the weighted technique for order of preference by similarity to ideal solution (TOPSIS) method. RESULTS: Among the 286 medical records evaluated, the main irrational manifestations were inappropriate indications (90 cases, 31.47%), auxiliary examination and laboratory examination did not meet the minimum requirements of combination chemotherapy drugs (40 cases, 13.99%), the drug course was not standard (39 cases, 13.64%). Among the included cases, 57.34% were reasonable cases (Ci⩾ 0.8), 10.84% were basic reasonable cases (0.6 ⩽Ci< 0.8), and 31.82% were unreasonable cases (Ci< 0.6). CONCLUSION: The TOPSIS method, with its attribute hierarchical model (AHM)-weighted approach, can be employed as the rational assessment technique for the injection of tislelizumab. The clinical application of tislelizumab in our hospital is still insufficient, which needs to be further improved management.

A wastewater-based evaluation of the effectiveness of codeine control measures in Australia.

BACKGROUND AND AIM: From 1 February 2018, codeine was rescheduled from an over-the-counter (OTC) to a prescription-only medicine in Australia. We used wastewater-based epidemiology to measure changes in population codeine consumption before and after rescheduling. METHODS: We analysed 3703 wastewater samples from 48 wastewater treatment plants, taken between August 2016 and August 2019. Our samples represented 10.6 million people, 45% of the Australian population in state capitals and regional areas in each state or territory. Codeine concentrations were determined by liquid chromatography-tandem mass spectrometry and converted to per-capita consumption estimates using the site daily wastewater volume, catchment populations and codeine excretion kinetics. RESULTS: Average per-capita consumption of codeine decreased by 37% nationally immediately after the rescheduling in February 2018 [95% confidence interval (CI) = 35.3-39.4%] and substantially in all states between 24 and 51% (95% CI = 22.4-27.0% and 41.8-59.4%). The decrease was sustained at the lower level to August 2019. Locations with least pharmacy access decreased by 51% (95% CI = 41.7-61.7%), a greater decrease than 37% observed for those with greater pharmacy access (95% CI = 35.1-39.4%). Regional areas decreased by a smaller margin to cities (32 versus 38%, 95% CI = 30.2-34.1% versus 34.9-40.4%, respectively) from a base per-capita usage approximately 40% higher than cities. CONCLUSION: Wastewater analysis shows that codeine consumption in Australia decreased by approximately 37% following its rescheduling as a prescription-only medicine in 2018. Wastewater-based epidemiology can be used to evaluate changes in population pharmaceutical consumption in responses to changes in drug scheduling.

Objective To establish the drug use evaluation ( DUE) of Dolasetron, evaluate the rationality of the clinical use of Dolasetron and provide a reference for the rationally clinical use of Dolasetron．Methods On the basis of Dolasetron DUE criteria, a retrospective analysis was made in 794 hospitalized patients from January 2021 to June 2021. Results The drug use evaluation criterion on Dolasetron consisted of drug indications, drug use process, the result of drug use and indication management. Conclusion There are some inappropriate medication problems in Dolasetron utilization in the hospital. The DUE criterion is very practical which could be used to standardize the clinical utilization of Dolasetron.

Impact of Antibiotic Authorisation at Three Provincial Hospitals in Thailand: Results from a Quasi-Experimental Study.

Implementing antimicrobial stewardship (AMS) at non-university hospitals is challenging. A quasi-experimental study was conducted to determine the impact of customised antibiotic authorisation implementation on antimicrobial consumption and clinical outcomes at three provincial hospitals in Thailand. Customised pre-authorisation of selected restricted antibiotics and post-authorisation of selected controlled antibiotics were undertaken and implemented at each hospital by the local AMS team with guidance from the AMS team at the university hospital. From January 2019−December 2020, there were 1802 selected patients (901 patients during the pre-implementation period and 901 patients during the post-implementation period). The most commonly used targeted antimicrobial was meropenem (49.61%), followed by piperacillin/tazobactam (36.46%). Comparison of the outcomes of the patients during the pre- and post-implementation periods revealed that the mean day of therapy of the targeted antimicrobials was significantly shorter during the post-implementation period (6.24 vs. 7.64 days; p < 0.001), the favourable clinical response (the improvement in all clinical and laboratory parameters at the end of antibiotic therapy) was significantly higher during the post-implementation period (72.70% vs. 68.04%; p = 0.03) and the mean length of hospital stay was significantly shorter during the post-implementation period (15.78 vs. 18.90 days; p < 0.001). In conclusion, implementation of antibiotic authorisation at provincial hospitals under experienced AMS team's guidance was feasible and useful. The study results could be a good model for the implementation of customised AMS strategies at other hospitals with limited resources.

Evaluation of antibiotic prophylaxis for gastrointestinal surgeries in a teaching hospital: An interventional pre-post study.

Surgical site infections are related to a high morbidity, mortality and healthcare costs. Despite ample evidence demonstrating the effectiveness of antimicrobials to prevent surgical site infections, inappropriate timing, antibiotic selection and excessive continuation of antibiotics are common in practice. In this study, we compare the appropriateness of antibiotic prophylaxis in gastrointestinal surgery, before and after an evidence-based guideline implementation. One hundred patients were evaluated in each group. The implementation of the guideline resulted in significant reduction of incorrect use of antibiotics from 55% to 18% (P = 0.002). It also reduced duration of prophylactic antibiotics (43% vs. 23%, P = 0.025). Inappropriate doses diminished but not significantly (8% vs. 5%, P = 0.321). Based on our results, in more than half of of these cases patients received incorrect antibiotic prophylaxis regimens for gastrointestinal surgery in this hospital. Local guideline implementation can result in reduction of antibiotic use, dose and duration errors.

The appropriateness of ceftriaxone utilization in government hospitals of Eastern Ethiopia: A retrospective evaluation of clinical practice.

INTRODUCTION: Drug use evaluation is a method of obtaining information to identify problems related to drug use and if properly developed, a means of correcting the problems. Ceftriaxone is among the most commonly utilized cephalosporins. Owing to a broad spectrum of activity and being used empirically, ceftriaxone has been used inappropriately posing a risk for development of antimicrobial resistance. This study is, therefore, designed to evaluate the appropriateness of ceftriaxone utilization in government hospitals in Harar town. METHODS: A retrospective cross-sectional study was conducted in four government hospitals of Harar town by reviewing the medical records of 271 patients who received ceftriaxone from 1 January to 31 December 2016. Systematic random sampling was utilized to capture the medical records. Data were entered and analyzed using SPSS version 22. RESULTS: From the 271 medical records reviewed majority of patients were from surgical ward (n = 85, 31.4%) followed by gynecology and obstetrics ward (n = 67, 24.7%). Demographically, the majority of the patients were female (n = 142, 52.4%). Patients in the age group of 20-29 years were dominant (n = 98, 36.2%). A total of 71 drugs were co-administered with ceftriaxone, the most common being metronidazole followed by tramadol. Among the co-administered drugs, unfractionated heparin (n = 6), warfarin (n = 5), and enoxaparin (n = 1) were found to have a moderate drug interaction with ceftriaxone. Ceftriaxone was commonly used for post-operative prophylaxis (n = 80, 27.5%) followed by for the management of pneumonia (n = 62, 21.3%). The result of ceftriaxone use evaluation showed that majority (n = 190, 70.1%) were found to be inappropriate. The inappropriate utilization was primarily due to wrong indication (indications for which ceftriaxone was not the primary option) (n = 114, 60.0%) followed by wrong duration (n = 54, 28.4%). CONCLUSION: Ceftriaxone was used inappropriately in more than two-thirds of the patients, with wrong indication and wrong duration contributing the majority. Inappropriate use of antibiotics may potentially lead to the emergence and spread of drug-resistant microorganisms and also ultimately exposes the patient to treatment failure, prolonged hospital stay, and higher cost of therapy.

Evaluation of drug prescription pattern using World Health Organization prescribing indicators in public health facilities found in Ethiopia: systematic reviews and meta-analysis.

BACKGROUND: Drug use evaluation is a structured, methodological, and criteria-based drug assessment system that helps to evaluate the actual trend of drug use in a particular setting. If drug prescription practices are inappropriate, need to examine the patterns of drug use is necessary to change prescribing patterns accordingly. Therefore, this review aimed to determine the drug prescription pattern in public health facilities found in Ethiopia using prescribing indicators developed by the World Health Organization. METHODS: This review was conducted as per the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guideline. Extensive searching to identify articles was conducted in PubMed, Medline, Web of Science, Research Gate, Africa Journal of Online, and Google scholar. Finally, 10 eligible articles were selected for analysis based on inclusion and exclusion criteria. The median value, as well as the 25th and 75th percentiles for each WHO prescribing indicator, were computed. RESULT: The pooled median value of WHO prescribing indicators was reported as follows: the average number of drugs prescribed per encounter = 2.14 (IQR 1.79-2.52), the percentage of encounters with antibiotics prescribed = 43.46% (IQR 30.01-58.67), the percentage of encounters with an injection prescribed = 13.20% (6.47-40.7), percentage of drugs prescribed by generic name = 93.49% (89.13-97.96), and the percentage of medicines prescribed from essential medicines list = 92.54% (85.10-97.7). The forest plots determined for each prescribing indicator indicated that there is a high degree of heterogeneity across articles. CONCLUSION: All of the prescribing indicators were not consistent with the standard values recommended by the World Health Organization. Therefore, public health facilities should take appropriate measures for improving the prescription patterns as per the recommendation set by the World Health Organization.

Establishment and application of DUE criteria for human albumin in pediatric patients / 中国临床药理学与治疗学

AIM: To provide reference for rational application of human albumin in pediatrics. METHODS: On the basis of the human albumin instructions, refer to the relevant guidelines and literature on the use of human albumin in pediatrics, draft the first draft of the Drug Use Evaluation standard and list it into an expert consultation questionnaire, which is finalized through two rounds of expert discussions. This standard was used to retrospectively evaluate the medical records of hospitalized children who used human albumin in the Pediatric Department of our hospital from June 2019 to January 2020. RESULTS: The standards established in this study included three primary indicators of medication indications, medication process, medication results and 6 secondary indicators of indications, contraindications, treatment process monitoring, drug application, efficacy, and adverse reactions. A total of 269 medical records of hospitalized children were included in this evaluation, of which newborns accounted for the highest proportion (56.88%). 229 cases met the indications, accounting for 85.13%; 251 cases were tested for serum albumin concentration before medication, accounting for 93.31%; after medication, the relevant indicators reached the standard, and the symptoms improved significantly in 226 cases, accounting for 84.01%. CONCLUSION: The Drug Use Evaluation criteria for pediatric human albumin established by our hospital has strong practicability, which is conducive to discovering problems or deficiencies in clinical medication and promoting rational clinical use of medication.

Drug Use Evaluation of Ceftriaxone in Ras-Desta Memorial General Hospital, Ethiopia.

BACKGROUND: Ceftriaxone is one of the most commonly used antibiotics due to its availability, wide spectrum of activity and low toxicity. However, irrational use of ceftriaxone is one of the current issues in most countries, especially developing ones. OBJECTIVE: The aim of this study was to evaluate ceftriaxone utilization in different wards of Ras-Desta Memorial General Hospital (RDMGH) in Ethiopia. METHODS: An institution-based retrospective cross-sectional study was conducted on randomly selected 1,079 patients who were admitted to RDMGH from May 2017 to April 2018. A structured data abstraction format was used to collect data from patients' medical chart. Micromedex® drug interaction checker was used to identify significant drug-drug interactions, and national and international guidelines were used to evaluate the appropriateness of ceftriaxone use. The data were analyzed by using SPSS version 20.0. RESULTS: Among the 1,079 patients enrolled, ceftriaxone was utilized by 601 (55.7%) patients, and these patients were considered for evaluation of appropriateness and subsequent analysis. Among 601 patients, ceftriaxone was used for therapeutic purpose in 362 (60.2%) patients; of which, 359 (99.2%) were for empiric therapy and the rest 239 (39.8%) were for prophylaxis. In the majority of the patients, the dose of ceftriaxone was 2g/day 472 (78.6%) and for a duration of 2-7 days 409 (68.1%). Inappropriate use of ceftriaxone was observed among 237 (39.4%) patients with regard to indication, dose/frequency and duration. About half (49.3%) of the deviation from the guidelines was observed from surgical and gynecologic/obstetrics wards. Among the co-prescribed medications with ceftriaxone, ringer lactate, warfarin and heparin were found to have a significant drug-drug interaction. CONCLUSION: This study revealed that inappropriate use of ceftriaxone was high in RDMGH. This may increase the emergence of resistant pathogens which may lead to treatment failure and increase cost of therapy. Therefore, adherence to current evidence-based guidelines is recommended.

Use of analgesics following rescheduling of codeine in Australia: An interrupted time series analysis in the veteran population.

BACKGROUND: The Australian medicines regulator, the Therapeutic Goods Administration (TGA), rescheduled all codeine-containing medicines to be available only on prescription on 1 February 2018. This study was conducted to determine whether use of analgesics changed following codeine re-scheduling to prescription only status, and whether there was a change in the use of codeine preparations and a therapeutic shift to stronger opioids or other analgesics in the Australian veteran population following the change. METHODS: Interrupted time series analysis using Repatriation Pharmaceutical Benefits Scheme (RPBS) claims data from the Australian Government Department of Veterans' Affairs (DVA) for clients with dispensing of opioid and non-opioid analgesics between January 2015 and April 2019. Trends in the monthly rate of analgesic dispensings (opioid and non-opioid) were compared for the period between January 2015 and January 2018 with the period February 2018 to April 2019. RESULTS: Paracetamol with codeine 8mg was the only analgesic with an increased rate of dispensing following the February 2018 codeine scheduling changes. Prior to codeine re-scheduling, the rate of dispensing of paracetamol with codeine 8mg was decreasing by 0.9% each month. Immediately after the scheduling changes, dispensing of paracetamol with codeine 8mg increased by 45% (95%CI=1.282-1.676, p<0.001) and in the fifteen month period thereafter (February 2018 to April 2019), the rate of dispensing increased by 4% each month (95%CI=1.027-1.054, p<0.001). Therapeutic shift from over-the-counter codeine products to other opioids was not observed, with no increase in the rate of dispensing of any of the other opioid (or non-opioid) analgesics following the codeine scheduling changes. CONCLUSION: A significant increase in prescription use of paracetamol with codeine 8mg was observed after the February 2018 codeine re-scheduling. Therapeutic shift to stronger opioid analgesics was not observed in the study population.

Drug use evaluation (DUE) of ceftriaxone: A quality metric in a pediatric hospital.

Background: Ceftriaxone is frequently used as empiric therapy because of its broad spectrum and dosing characteristics. The purpose of this study was to evaluate the appropriateness of ceftriaxone therapy among hospitalized children using drug use evaluation (DUE) methodology. Methods: Hospitalized patients who received one or fewer dose of intravenous ceftriaxone at Children's Hospital of Eastern Ontario between January 1, 2018, and June 30, 2018, were identified. Duration was defined as empiric if 72 or less and definitive if more than 72 hours. Two infectious disease physicians reviewed the charts and rated appropriateness using a previously developed scale. Results: A total of 276 ceftriaxone courses in 248 patients (mean age 6.0 y) were reviewed. Of these, 153 (55.4%) were assessed as definitively or possibly indicated. The most common reason for inappropriate empiric use was an overly broad spectrum. Of the 120 courses given empirically for which there was no indication, the three most common reasons were lower respiratory infections (51; 42.5%), head and neck infections (18; 15.0%), and intra-abdominal infections (15; 12.5%). Of the 39 (14.1%) courses of ceftriaxone that were given for more than 72 hours, 14 (35.9%) met criteria for a definitive or possible indication. Conclusion: Ceftriaxone is still overused as empiric therapy. Although 85% of courses were discontinued after three doses, 14% were continued for longer than 72 hours, with approximately one-third ultimately meeting an indication. DUE using Canadian pediatric and local guidelines criteria is useful to identify clinical presentations for which narrower spectrum antimicrobials should be used.

Historique: La ceftriaxone est souvent utilisée comme traitement empirique en raison de son large spectre et de ses caractéristiques posologiques. La présente étude visait à évaluer la pertinence d'un traitement à la ceftriaxone chez les enfants hospitalisés, à l'aide de la méthodologie d'évaluation de la consommation des médicaments (ÉCM). Méthodologie: Les chercheurs ont recensé les patients hospitalisés qui ont reçu un maximum d'une dose de ceftriaxone par voie intraveineuse au Centre hospitalier pour enfants de l'est de l'Ontario entre le 1er janvier 2018 et le 30 juin 2018. La durée était définie comme empirique si elle était de 72 heures ou moins et comme décisive si elle était supérieure à 72 heures. Deux infectiologues ont examiné les dossiers et classé la pertinence au moyen d'une échelle déjà existante. Résultats: Au total, les chercheurs ont examiné 276 traitements de ceftriaxone chez 248 patients (d'un âge moyen de 6,0 ans). De ce nombre, 153 (55,4 %) ont été évalués comme définitifs ou possibles. Un trop large spectre était la principale raison d'en faire un usage empirique inapproprié. Les trois principales raisons d'administrer les 120 traitements empiriques sans indication étaient les infections des voies respiratoires inférieures (51; 42,5 %), les infections de la tête et du cou (18; 15,0 %) et les infections intra-abdominales (15; 12,5 %). Des 39 traitements de ceftriaxone (14,1 %) administrés pendant plus de 72 heures, 14 (35,9 %) avaient respecté les critères d'une indication définitive ou possible. Conclusion: La ceftriaxone demeure surutilisée comme traitement empirique. Même si 85 % des traitements ont été abandonnés après trois doses, 14 % se sont poursuivis plus de 72 heures, et au bout du compte, environ le tiers répondait à une indication. L'ÉCM faisant appel aux critères des directives canadiennes locales en pédiatrie est utile pour déterminer les présentations cliniques qui justifient l'utilisation d'antimicrobiens à spectre plus étroit.

Prescribing Pattern of Proton Pump Inhibitors in Qatar Rehabilitation Institute: A Retrospective Study.

OBJECTIVE: Proton pump inhibitors (PPIs) are still widely used despite increasing reports of their adverse events. This drug use evaluation study was conducted to assess the prescribing pattern of PPIs for patients admitted to the Qatar Rehabilitation Institute (QRI). METHODS: An observational, retrospective, patients' chart-based study included all patients who received a PPI in QRI between April 1, 2017, and October 1, 2017. A standardized tool was prepared and reviewed by the involved clinical pharmacists to collect appropriate data for the evaluation. Statistical analysis was performed using the 25th Version of the Statistical Package of the Social Sciences (SPSS®). FINDINGS: A total of 119 patients received PPIs during the audit period, of which esomeprazole was the most frequently prescribed (34%). Majority of the patients (94%) were started on PPI without further investigations for confirming the indication, and the indication was not documented in 78% of the participants. Nonsteroidal anti-inflammatory drugs were the most commonly co-prescribed medications with PPIs (59%). Pantoprazole was co-prescribed with clopidogrel in 42% of the patients. CONCLUSION: This drug utilization study shows the need for a proper prescribing practice considering a clear indication and recommendations about the duration of therapy and the need for reassessment in QRI.

Factors related to inappropriate edoxaban use.

WHAT IS KNOWN AND OBJECTIVE: The aim of this study was to evaluate the appropriateness and clinical outcomes of edoxaban use, and to determine the role of clinical pharmacists in improving the efficacy and safety of edoxaban use. METHODS: A retrospective study was performed by using an electronic medical record and anticoagulation clinical data from 600 patients who received edoxaban from 1 March 2016 to 16 July 2017 at a tertiary teaching university hospital. The appropriateness of edoxaban use was assessed using eight criteria based on drug use evaluation criteria developed by the American Society of Health-System Pharmacists drug use evaluation guidelines, details in Korea Food and Drug Administration approval of edoxaban. Clinical outcomes were evaluated between the appropriately prescribed and inappropriately prescribed groups regarding the incidence of thrombosis and bleeding episodes. RESULTS AND DISCUSSION: After excluding 86 patients due to the inability to assess renal function, 514 were eligible. Appropriate use was found in 294 patients (57.2%). The most frequent inappropriate use of edoxaban was dose adjustment (60.8%) in accordance with the dosing recommendation in patients with renal insufficiency (creatinine clearance [CrCl] of 15-50 mL/min) and a low body weight of <60 kg. Moreover, there were three cases of edoxaban use in patients with prosthetic heart valves and moderate-to-severe mitral stenosis, and 15 cases of non-valvular atrial fibrillation in patients with CrCl >95 mL/min in whom edoxaban use is not recommended. Furthermore, we found that the factors related to the appropriateness of edoxaban use were <60 kg body weight (adjusted odds ratio [OR]: 0.310; confidence interval [CI]: 0.197-0.488) and CrCl <50 mL/min (adjusted OR: 0.629; CI: 0.404-0.980). There were 45 events (8.75%) of any bleeding, 9 (1.8%) of stroke/transient ischaemic attack (TIA) and four events (0.8%) of deep vein thrombosis (DVT)/pulmonary embolism (PE). However, there was no difference between the appropriately prescribed group (294 patients) and inappropriately prescribed group (220 patients) in the incidence of bleeding events (27 [9.2%] vs 18 [8.2%]), stroke/TIA (7 [2.4%] vs 2 [0.9%]) and DVT/PE (2 [0.7%] vs 2 [0.9%]), respectively. WHAT IS NEW AND CONCLUSION: Although edoxaban has a broad therapeutic window that does not require routine monitoring, it should be cautiously used in patients with renal insufficiency (CrCl <50 mL/min) and body weight <60 kg.

Assessment of the Appropriateness of Ceftazidime Use in a Tertiary Teaching Hospital, Northern Ethiopia.

BACKGROUND: Ceftazidime is nowadays one of the most commonly used antibiotics due to its high antibacterial potency, wide spectrum of activity, and low potential for toxicity. However, the global trend shows huge misuse of ceftazidime. OBJECTIVE: This study was conducted to assess the appropriateness of ceftazidime use and to identify areas of intervention to prevent inappropriate use in different wards of Ayder Compressive Specialized Hospital, a tertiary teaching Hospital, Mekelle-Ethiopia. METHODS: A facility-based prospective cross-sectional study design was steered on 327 patients who received ceftazidime during their hospitalization in the selected wards from February 1 to April 30, 2019. RESULTS: In the assessment of the appropriateness of ceftazidime use, 2,084 (70.8%) were appropriate. Appropriateness of indication was 295 (90.2%), the effectiveness of ceftazidime use was 221 (67.6%), correct dose of ceftazidime use was 264 (80.4%), and the correct frequency of ceftazidime use was 230 (70.3%). Its use was empiric in 275 participants (84.1%) and specific in 52 (15.9%) participants. The most common indication for ceftazidime use was uncomplicated pneumonia, at 112 (34.3%). One hundred and seventy-one (52.3%) participants had intervention to prevent inappropriate use of ceftazidime. Changing the drug combination (96, 29.4%), increasing the dose (13, 4%), decreasing the dose (21, 6.4%), holding the (21, 6.4%), and discontinuation of ceftazidime (20, 6.1%) were among the interventions. CONCLUSION: This study revealed that more than one-fourth of the ceftazidime use was inappropriate. This may lead to the emergence of resistant pathogens which in turn lead to treatment failure and increased the cost of therapy. Therefore, adherence to current evidence-based guidelines and initiating antimicrobial stewardship are recommended.

Appropriateness of Cotrimoxazole Prophylactic Therapy Among HIV/AIDS Patients in Public Hospitals in Eastern Ethiopia: A Retrospective Evaluation of Clinical Practice.

Background: Cotrimoxazole prophylactic therapy (CPT) is a feasible, cost-effective, and safe way of using cotrimoxazole intervention to reduce HIV/AIDS related morbidities and mortalities associated with opportunistic infections. Despite its effectiveness in reducing the incidence of opportunistic infections, the actual drug utilization process has been shown to deviate from World Health Organization (WHO) guideline in Ethiopia. This study, therefore, aims to evaluate CPT among HIV/AIDS patients in Jugel Hospital (JH), Harar and Dilchora Referral Hospital (DRH), Dire Dawa, Eastern Ethiopia. Methods: A cross sectional study was conducted to evaluate the use of cotrimoxazole as prophylactic therapy. In this study, 556 medical records (305 in JH and 251 in DRH) of HIV/AIDS patients who had been taking CPT within September 2015-August 2016 were reviewed. Systematic random sampling was employed to obtain medical records from the sampling frame. Data were abstracted from the patient medical records using structured checklist customized from the WHO guideline. The data were entered into Epi-data 3.1 and exported to and analyzed with statistical Package for Social Sciences (SPSS) version 20. The finding was evaluated against the WHO guideline on the use of cotrimoxazole prophylaxis in HIV/AIDS patients. Descriptive statistics was used to present the data in tables, figures and pie chart. Results: Majority of the HIV/AIDS patients who had been taking CPT were adults (95.9%), female (61.2%), married (43.7%), Orthodox Christian (54.3%), and attended primary school (40.1%). At the initiation of CPT, most of the patients were at WHO clinical stage III (40.8%). The major comorbid illnesses identified were tuberculosis and pneumocystis-jiroveci pneumonia. Initially, majority of the patients were at CD4 count of less than 350 cells/mm3 (n = 504, 90.6%). Greater proportion of patients started CPT prior to initiating antiretroviral therapy (ART). Most of the patients took CPT for greater than 6 months. The primary reasons for premature discontinuation of CPT were CD4 greater than 350 cells/mm3, severe sulfa allergy and first trimester of pregnancy. Generally, the use of cotrimoxazole prophylaxis was consistent with the WHO guideline for indication to start (n = 519, 93.3%) and dose (n = 552, 99.28%), despite the presence of contraindication in 6.65% patients. Conclusion: In reference to the WHO guideline, the use of CPT was found to be fully appropriate in nearly two-thirds of HIV/AIDS patients. For the rest patients, inappropriate use of cotrimoxazole was observed based on the WHO criteria for initiation, discontinuation, continuation and dose with rate of discontinuation being the dominant one. Such practice may lead to adverse health outcomes including adverse drug reactions and negative treatment outcome.

Polypharmacy among patients with diabetes: a cross-sectional retrospective study in a tertiary hospital in Saudi Arabia.

ObjectivesPatients with diabetes are at high risk for polypharmacy (ie, use of multiple medications) for treatment of diabetes, associated comorbidities and other coexisting conditions. This study aims to estimate the prevalence of polypharmacy and factors associated with polypharmacy among adult patients with diabetes. METHODS: A cross-sectional retrospective observational study of adults with diabetes, who visited the outpatient clinic of a tertiary teaching hospital in Saudi Arabia, was conducted. Data were extracted from the Electronic Health Record database for a period of 12 months (January-December 2016). Polypharmacy was defined as the cumulative use of five or more medications. Polypharmacy among adults with diabetes was measured by calculating the average number of medications prescribed per patient. A multivariable logistic regression model was used to examine the factors associated with polypharmacy. RESULTS: A total of 8932 adults with diabetes were included in this study. Of these, nearly 78% had polypharmacy which was more likely among women as compared with men and more likely among older adults (age ≥60 years) as compared with the adults. Also, polypharmacy was two times as likely among patients with coexisting cardiovascular conditions (adjusted OR (AOR)=2.89; 95% CI 2.54 to 3.29), respiratory disease (AOR=2.42; 95% CI 1.92 to 3.03) and mental health conditions (AOR=2.19; 95% CI 1.74 to 2.76), and three times as likely among patients with coexisting musculoskeletal disease (AOR=3.16; 95% CI 2.31 to 4.30) as compared with those without these coexisting chronic conditions categories. CONCLUSIONS: Polypharmacy is common among patients with diabetes, with an even higher rate in older adults patients. Healthcare providers can help in detecting polypharmacy and in providing recommendations for simplifying medication regimens and minimising medications to enhance the outcome of diabetes care.

Predicting Factors for the Pattern of Intravenous Immunoglobulin Utilization in a Middle Eastern University Hospital.

OBJECTIVE: The dramatic increase in the consumption of intravenous immunoglobulin (IVIG) products in nonapproved indications, its high cost, and the severe shortage has developed the concerns of its irrational utilization, especially in the Middle East countries. Therefore, this clinical study attempts to describe the pattern of IVIG administration in one of the largest hospitals in Iran and find the variables associated with inappropriate IVIG utilization. METHODS: This cross-sectional medication utilization study was conducted in one of the largest referral hospitals in Iran. Random IVIG administrations were assessed from different wards for 9 months. Different data were collected to evaluate the pattern of IVIG administration and find variables, which could predict this behavior. FINDINGS: IVIG was prescribed for approved indications in 72% of 201 patients recruited in our study. Although, the rate of drug administration was appropriate in most of the study population, hydration and pre-medication were unsuitable in more than one-third of the patients. Among the variables analyzed to find the factors affecting the misuse of IVIG, female gender, older age of patients, and longer time to start IVIG administration due to hospital admission were statistically significant in the multivariate model. CONCLUSION: Despite the fact that inappropriate use of IVIG was confirmed in less than 30 % of its utilization for the studied patients, it caused a potential risk of treatment complications and a notable and unjustifiable burden of unnecessary costs for this University hospital.

A pilot study evaluating the prescribing of ceftriaxone in hospitals in Ghana: findings and implications.

BACKGROUND AND OBJECTIVES: Widespread empiric use of antibiotics exists especially in developing countries. This is a concern since inappropriate use of antibiotics, including their extended inappropriate use, will increase resistance rates. Consequently, there is a need to evaluate antibiotic utilisation across healthcare sectors to improve future use. This includes ceftriaxone, widely used among hospitals including those in Ghana. METHODS: A cross-sectional study to evaluate the appropriateness of ceftriaxone prescribing in a leading hospital in Ghana. Ceftriaxone prescribing in patient-record cards was assessed using a modified WHO drug-utilization evaluation criteria as well as referencing the national standard treatment guidelines in Ghana and the ceftriaxone package insert. RESULTS: A total of 251 patients were assessed. Ceftriaxone was most commonly prescribed for comorbid malaria with bacterial infections, urinary tract infections, sepsis and gastroenteritis. The appropriateness of the indication was 86% (n = 218). The doses most prescribed were 1g (41%) and 2g (39%). Stat dose and once-daily dosage regimen constituted 51.4% and 84.5%, respectively. The most common duration of treatment was 1 (51.4%) and 2 days (35.1%). The overall appropriateness of prescribing was 93% against a pre-set threshold of 97%. CONCLUSION: The appropriateness of ceftriaxone prescribing was high in this leading hospital in Ghana; however, there is room for improvement with targeted education initiatives, with further research planned.
