Awareness of Antimicrobial Resistance and Antimicrobial Drugs Prescription Pattern in Small Animal Clinical Practice in Ogun State, Nigeria

Antimicrobial resistance (AMR) is a global health challenge in veterinary and human health, leading to monitoring of resistance and promotion of responsible antimicrobial use. This survey assessed the use of antimicrobials among government veterinarians in Ogun state, Nigeria. Clinicians were requested to fill questionnaires designed to extract information on the frequency of antibiotics use, antibiotic prescription patterns and evaluation of perception on AMR and use of antibiotics with compromised efficacy in veterinary practice in the last three years. Fifty-two (52) questionnaires were administered and duly completed upon return. Data analysis showed 100% awareness of AMR with 80.8% (42/52) agreeing to have encountered AMR in the course of managing small animal cases. The tetracycline class of antibiotics 49(94.2%) was the most prescribed, followed by aminoglycosides 40(76.9%) and fluoroquinolones 35(67.3%). Empirical therapy (34/52) 65.4% is the most common treatment option among clinicians while 18 (34.6%) out of 52 clinicians performed antibiotic susceptibility testing along with laboratory diagnosis as treatment guide. Furthermore, 75.0% of the respondents affirmed administering antibiotics formulated for human use in small animal treatment. Thirty-three (63.5%) respondents administered human antimicrobials in animals according to the recommended dosage in humans. This survey identified that AMR was common in small animals in the state studied and this may be due to the irrational use of antibiotics. Promoting antimicrobial stewardship in small animal medicine therefore is paramount to mitigating antimicrobial resistance and data obtained from this study will contribute to developing evidence-based policy on the rational use of antibiotics in small animal practice in Nigeria.

Antimicrobial Prescription Patterns for Acute Sinusitis 2015-2022: A Comparison to Published Guidelines.

Acute rhinosinusitis (ARS) is one of the most encountered conditions in primary care and otolaryngology clinics. However, little is known about how antibiotic prescription practices following a diagnosis of ARS compare to guidelines set forth by the American Academy of Otolaryngology in 2015. To investigate the epidemiology of ARS and the corresponding antibiotic prescribing practices by physicians and compare to published guidelines. Using the TriNetX Live database, we identified all patients diagnosed with ARS using the ICD10 code J01 between April 2015 and December 2022 across the state of Tennessee. After investigating the demographics of this cohort, we compared the first prescribed antibiotic within one day of ARS diagnosis to published guidelines. Antibiotics were grouped into their respective classes. Of 81 310 patients diagnosed with ARS identified in the specified time frame, 66% were Female, 49% were African American, 44% were White, and the mean age was 47 ± 20 years. The six most common initial antibiotics prescribed for ARS were erythromycins/macrolides [14 609 (25.8%)], amoxicillin/clavulanate [14 322 (25.3%)], amoxicillin [9300 (16.4%)], third generation cephalosporins [7733 (13.6%)], quinolones [3648 (6.4%)] and tetracyclines [2235 (3.9%)]. Of this cohort, 56 719 patients (69.8%) of patients were prescribed an antibiotic within one day of diagnosis. Despite published guidelines recommending amoxicillin with or without clavulanic acid as first-line treatment for ARS, only 42.2% of prescribed antibiotics followed this guideline in our cohort. While accounting for patients with penicillin allergy, the second-most represented antibiotics were erythromycins/macrolides, which are specifically recommended against due to high rates of S. Pneumoniae resistance. Our results suggest that further investigation into the causes of erythromycin/macrolide prescriptions as first line treatment for ARS and practices at other institutions should be conducted. In addition, building awareness around published ARS guidelines for physicians may be useful in improving antibiotic stewardship in treatment of ARS.

Antimicrobial prescription pattern and appropriateness for respiratory tract infection in outpatients: a systematic review and meta-analysis

BackgroundMillions of people die every year as a result of antimicrobial resistance worldwide. An inappropriate prescription of antimicrobials (e.g., overuse, inadequate use, or a choice that diverges from established guidelines) can lead to a heightened risk of antimicrobial resistance. This study aimed to determine the rate and appropriateness of antimicrobial prescriptions for respiratory tract infections.MethodsThis review was conducted in accordance with the PRISMA guidelines. Web of Science, PubMed, ProQuest Health and Medicine, and Scopus were searched between October 1, 2023, and December 15, 2023, with no time constraints. Studies were independently screened by the first author and the co-authors. We included original studies reporting antimicrobial prescription patterns and appropriateness for respiratory tract infections. The quality of included studies’ was assessed via the Joanna Briggs Institute’s Critical Appraisal Checklists for Cross-Sectional Studies. The assessment of publication bias was conducted using a funnel plot and Egger’s regression test. A random effect model was employed to estimate the pooled antibiotic prescribing and inappropriate rates. Subgroup analysis was conducted by country, study period, data source, and age group.ResultsOf the total 1220 identified studies, 36 studies were included in the review. The antimicrobial prescribing rate ranged from 25% (95% CI 0.24–0.26) to 90% (95% CI 0.89–0.91). The pooled antimicrobial prescription rate was 66% (95% CI 0.57 to 0.73). Subgroup analysis by region revealed that the antimicrobial prescription rate was highest in Africa (79%, 95% CI 0.48–0.94) and lowest in Europe (47%, 95% CI 0.32–0.62). Amoxicillin and amoxicillin-clavulanate antimicrobials from the Access group, along with azithromycin and erythromycin from the Watch group, were the most frequently used antimicrobial agents. This study revealed that the major reasons for antimicrobial prescription were acute bronchitis, pharyngitis, sinusitis, and the common cold. The pooled inappropriate antimicrobial prescription rate was 45% (95% CI 0.38–0.52). Twenty-eight of the included studies reported that prescribing antimicrobials without proper indications was the main cause of inappropriate antimicrobial prescriptions. Additionally, subgroup analysis by region showed a higher inappropriate antimicrobial prescription rate in Asia at 49% (95% CI 0.38–0.60). The result of the funnel plot and Egger’s tests revealed no substantial publication bias (Egger’s test: p = 0.268).ConclusionThe prescribing rate and inappropriate use of antimicrobials remain high and vary among countries. Further studies should be conducted to generate information about factors contributing to unnecessary antimicrobial prescriptions in outpatients.Systematic review registrationSystematic review registration: CRD42023468353.

FilmArray Meningitis/Encephalitis Panel Impact on Antibiotic Usage in Patients with Suspected Community-Acquired Meningitis

Background: Cerebrospinal fluid (CSF) cultures are commonly performed to evaluate patients with suspected bacterial meningitis. These cultures, however, can take up to 72 hours, leading to delays in antibiotic de-escalation and increased antimicrobial utilization. The turnaround for the BioFire® FilmArray® Meningitis/Encephalitis(FA/ME) panel is less than an hour, which may facilitate early de-escalation. Our study aimed to assess whether the use of FA/ME panels in combination with CSF cultures could impact antimicrobial therapy compared to cultures alone in patients treated for suspected bacterial meningitis. Methods: Our retrospective study included patients from five hospitals in Texas (2017-2023) who received empiric antibiotics for suspected community-acquired meningitis and underwent a lumbar puncture within 96 hours of admission. Patients with ventricular drains, traumatic brain injury, and non-central nervous system infections were excluded. Cases comprised patients who had an FA/ME panel performed, while controls included patients without the panel. Outcomes were defined as the empiric duration of antimicrobial therapy (days) and total days of antibiotic therapy (DOT). Wilcoxon Rank Sum test and multiple linear regression models were applied to assess the relationship between the use of the FA/ME panel and study outcomes. Independent variables comprised demographics, institution type, acuity, clinical presentation, CSF values, and FA/ME panel use. Imputation was performed using multiple imputation by chained equations. Results: A total of 193 patients were included in our study. Seventy-one patients received the FA/ME panel (along with the CSF culture), while 122 patients received the CSF culture alone (controls). The median empiric duration of antibiotic therapy in the cases and controls were 1.71 days and 1.18 days, respectively (p = .160). The median DOT in the cases and controls were eight days and six days, respectively (p = .045). After adjusting for confounders, the FA/ME panel was not significantly associated with changes in the empiric duration of antibiotic therapy (B= 0.18, p = .669, Figure 1) or DOT (B= 1.28, p = .170, Figure 2).Conclusion: Providing FA/ME panel testing without active antimicrobial stewardship interventions did not result in a change in antimicrobial prescribing patterns. The difference from prior literature could be explained by the smaller sample size, limiting the power of the study. Further prospective antimicrobial stewardship efforts should focus on training providers on interpreting FA/ME panel results and providing prospective audits and feedback.

Assessment of antimicrobial prescribing patterns, guidelines compliance, and appropriateness of antimicrobial prescribing in surgical-practice units: point prevalence survey in Malaysian teaching hospitals.

Objectives: This study sought to investigate the quality of antimicrobial prescribing among adult surgical inpatients besides exploring the determinants of non-compliance and inappropriate prescribing to inform stewardship activities. Methods: A cross-sectional point prevalence study employing Hospital National Antimicrobial Prescribing Survey (Hospital NAPS) was conducted in April 2019 at two teaching hospitals in Malaysia. Results: Among 566 surgical inpatients, 44.2% were receiving at least one antimicrobial, for a total of 339 prescriptions. Antimicrobials belonging to the World Health Organization's Watch group were observed in 57.8% of cases. Both hospitals exhibited similar types of antimicrobial treatments prescribed and administration routes. A significant difference in antimicrobial choice was observed between hospitals (p < 0.001). Hospital with electronic prescribing demonstrated better documentation practice (p < 0.001). Guidelines compliance, 32.8% (p = 0.952) and appropriateness, 55.2% (p = 0.561) did not significantly differ. The major contributors of inappropriateness were incorrect duration, (15%) and unnecessary broad-spectrum coverage, (15.6%). Non-compliance and inappropriate prescribing were found to be 2 to 4 times significantly higher with antimicrobial prophylaxis prescription compared to empirical therapy. Conclusion: Antimicrobial stewardship efforts to improve appropriate surgical prescribing are essential. These initiatives should prioritize surgical prophylaxis prescribing, focusing on reducing unnecessarily prolonged use and broad-spectrum antimicrobials, raising awareness among prescribers and promoting proper documentation.

Antimicrobial Stewardship in the Emergency Department Observation Unit: Definition of a New Indicator and Evaluation of Antimicrobial Use and Clinical Outcomes.

We aimed to define a novel indicator for monitoring antimicrobial use specifically in the Emergency Department Observation Unit (EDOU) and to assess the long-term impact of an institutional education-based antimicrobial stewardship program (ASP) on the antimicrobial prescribing pattern and clinical outcomes in this setting. A quasi-experimental interrupted time-series study was performed from 2011 to 2022. An educational ASP was implemented at the EDOU in 2015. To estimate changes in antimicrobial use, we designed an indicator adjusted for patients at risk of antimicrobial prescribing: defined daily doses (DDDs) per 100 patients transferred from the Emergency Department to the Observation Unit (TOs) per quarter. The number of bloodstream infections (BSIs) and the crude all-cause 14-day mortality were assessed as clinical outcomes. Antimicrobial use showed a sustained reduction with a trend change of -1.17 DDD per 100 TO and a relative effect of -45.6% (CI95% -64.5 to -26.7), particularly relevant for meropenem and piperacillin-tazobactam, with relative effects of -80.4% (-115.0 to -45.7) and -67.9% (-93.9 to -41.9), respectively. The incidence density of all BSIs increased significantly during the ASP period, with a relative effect of 123.2% (41.3 to 284.7). The mortality rate remained low and stable throughout the study period, with an absolute effect of -0.7% (-16.0 to 14.7). The regular monitoring of antimicrobial use in the EDOU by using this new quantitative indicator was useful to demonstrate that an institutional education-based ASP successfully achieved a long-term reduction in overall antimicrobial use, with a low and steady BSI mortality rate.

Dispensing of Antimicrobial Agents Without a Prescription in Iraq: A Call for Upholding the Legislations to Change Long-Standing Practices

Background: Antimicrobial prescribing patterns have an important role in the emergence of resistance, and community pharmacists have a substantial influence on this issue. Objective: To assess community pharmacists' behaviors and attitudes toward antimicrobial dispensing, determine their proportions and categories, and examine the underlying rationales for this practice. Methods: A descriptive cross-sectional survey of community pharmacists in Iraq was conducted from June to August 2023, using a self-administered validated questionnaire. The attitudes, practices, and motivations driving the distribution of antimicrobials without a prescription (AWP) were explored in three areas. Results: A sizable proportion (61.6%) of respondents rejected dispensing AWP at community pharmacies. Patients primarily seek antibacterials from community pharmacies owing to budget constraints, according to 82.7% of respondents, rather than for consultation and diagnostic services. The most powerful element in a pharmacist's decision to administer AWP is that patients will seek antimicrobials from another pharmacy if they are not dispensed by the pharmacist, owing to the pharmacist's experience in infection management. The study found that 50%–74% of patients who visited community pharmacies sought AWP. Antimicrobials are most commonly provided without a prescription for cold and flu and urinary tract infections (37.3% and 27.7%, respectively). Conclusions: The majority of pharmacists regularly dispense AWP. To guarantee compliance with Iraqi legislation and laws governing AWP distribution, ongoing training programs should be created to educate the public on the most effective methods.

Prescription Pattern in patients with Acute Tonsillitis, attending Outpatient Department

Background: Acute tonsillitis is a major health problem among children and adults which is badly effects the quality of life. Aim: To determine the antimicrobial prescription pattern in patients with acute tonsillitis, attending ENT OPD of Kulsumbai Valika, Social Security, Post Graduate Teaching Hospital Karachi.. Methodology: This cross-sectional study was conducted among the patients attending the outpatient of ENT, with acute tonsillitis. Study was conducted in Outpatient of ENT department of Kulsumbai Valika Social Security S.I.T.E. Hospital, Karachi. from 1st January 2023 to 31st December 2023. Data collection was done from the prescription of each patient. Statistical analysis was carried out using SPSS version 23. Results: A total of 210 acute tonsillitis patients, with 116(55.23%) were male. Mean number of the drugs in prescription 4±1.4. All the prescriptions included antimicrobials, 185(88%), and NSAIDs. Amoxicillin / Clavulanic acid (24.8%) and Ceftriaxone (12.2%) were the most commonly prescribed antimicrobials. Parenteral route was preferred in 113(53.8%). None of the patients was offered culture or sensitivity test of the microorganisms. Practical implication: Acute tonsillitis patients admitted and started parenteral antibiotic along with anti-inflammatory drugs. Conclusion: Antimicrobials thosewere prescribed in almost all cases of acute tonsilitis, and most frequently prescribed were Amoxicillin / Clavulanic acid and Cefixime. Injectable antibiotics were also prescribed very frequently. Most of the patients were given just one antibiotic. This study findings highlighted the gaps the rational practices in drug prescribing for acute tonsilitis. Keywords: Acute tonsillitis, Amoxicillin,antimicrobials, Clavulanic acid, Cefixime, prescription.

Global-PPS targets for antimicrobial stewardship in paediatric patients at hospitals in Sanandaj, Western Iran, compared with Southeast Asian and European hospitals

Point prevalence surveys (PPS) provide valuable data on patterns of hospital antimicrobial administration. To identify quality improvement indicators, we evaluated antimicrobial prescribing patterns in children and neonates admitted to three referral centres in Sanandaj, Western Iran, and compared these with Southeast Asian and European paediatric benchmark data. The standardised Global-PPS was performed to assess antimicrobial use in Southeast Asia, including Sanandaj and European hospitals, in 2019. Of the 4118, 2915, and 443 paediatric patients enrolled in Southeast Asian, European and Sanandaj hospitals, 2342 (56.9%), 833 (28.6%) and 332 (74.9%), respectively, received at least one antimicrobial in 2019. The most administered antibiotics in neonates were ampicillin in Southeast Asia (30.3%) and Sanandaj (41.5%, often in combination with cefotaxime (29.0%)), compared with amoxicillin in Europe (20.0%). In children, ceftriaxone was most prescribed in Sanandaj (62.4%) and Southeast Asia (20.5%) as opposed to amoxicillin (11.8%) in Europe. Twice as many Watch antibiotics (83.0%) were prescribed on paediatric wards in Sanandaj compared with European paediatric wards (41.1%). All antimicrobials in Sanandaj hospitals were prescribed empirically, and prolonged surgical prophylaxis was common (75.5%). The high prevalence of antibiotic prescribing, high empirical therapies, and poor outcomes for antibiotic quality indicators strongly suggest the urgent need for an antibiotic stewardship program in Sanandaj hospitals, where improved diagnostic laboratory capacity and reconsideration of training may be good targets for intervention in their hospitals.

Difference in Baseline Antimicrobial Prescription Patterns of Hospitals According to Participation in the National Antimicrobial Monitoring and Feedback System in Korea.

This study aimed to evaluate the differences in the baseline characteristics and patterns of antibiotic usage among hospitals based on their participation in the Korea National Antimicrobial Use Analysis System (KONAS). We obtained claims data from the National Health Insurance for inpatients admitted to all secondary- and tertiary-care hospitals between January 2020 and December 2021 in Korea. 15.9% (58/395) of hospitals were KONAS participants, among which the proportion of hospitals with > 900 beds (31.0% vs. 2.6%, P < 0.001) and tertiary care (50.0% vs. 5.2%, P < 0.001) was higher than that among non-participants. The consumption of antibiotics targeting antimicrobial-resistant gram positive bacteria (33.7 vs. 27.1 days of therapy [DOT]/1,000 patient-days, P = 0.019) and antibiotics predominantly used for resistant gram-negative bacteria (4.8 vs. 3.7 DOT/1,000 patient-days, P = 0.034) was higher in KONAS-participating versus -non-participating hospitals. The current KONAS data do not fully represent all secondary- and tertiary-care hospitals in Korea; thus, the KONAS results should be interpreted with caution.

Ground level utility of Access, Watch, Reserve classification: Insights from a tertiary care center in North India.

The overuse and misuse of antimicrobials contribute significantly to antimicrobial resistance (AMR), which is a global public health concern. India has particularly high rates of AMR, posing a threat to effective treatment. The World Health Organization (WHO) Access, Watch, Reserve (AWaRe) classification system was introduced to address this issue and guide appropriate antibiotic prescribing. However, there is a lack of studies examining the prescribing patterns of antimicrobials using the AWaRe classification, especially in North India. Therefore, this study aimed to assess the prescribing patterns of antimicrobials using the WHO AWaRe classification in a tertiary care centre in North India. To study the prescribing patterns of antimicrobials using WHO AWaRe classification through a cross-sectional study in All India Institute of Medical Sciences Rishikesh. A descriptive, cross-sectional study was conducted from July 2022 to August 2022 at a tertiary care hospital. Prescriptions containing at least one antimicrobial were included in the study. Data on prescriptions, including patient demographics, departments, types of antimicrobials prescribed, and duration of treatment, were collected. A questionnaire-based survey was also conducted to assess the knowledge and practices of prescribing doctors regarding the utility of AWaRe classification. The study involved a total of 123 patients, each of whom received at least one antimicrobial prescription. Most prescriptions were for inpatients, evenly distributed between Medicine (Internal medicine, Pediatrics, Dermatology) and Surgical departments (General surgery and specialties, Otorhinolaryngology, Ophthalmology, Obstetrics and Gynecology). Metronidazole and ceftriaxone were the most prescribed antibiotics. According to the AWaRe classification, 57.61% of antibiotics fell under the Access category, 38.27% in Watch, and 4.11% in Reserve. Most Access antibiotics were prescribed within the Medicine department, and the same department also exhibited a higher frequency of Watch antibiotics prescriptions. The questionnaire survey showed that only a third of participants were aware of the AWaRe classification, and there was a lack of knowledge regarding AMR and the potential impact of AWaRe usage. This study highlights the need for better antimicrobial prescribing practices and increased awareness of the WHO AWaRe classification and AMR among healthcare professionals. The findings indicate a high proportion of prescriptions falling under the Access category, suggesting appropriate antibiotic selection. However, there is a significant difference between the WHO Defined Daily Dose and the prescribed daily dose in the analysed prescriptions suggesting overuse and underuse of antibiotics. There is room for improvement and educational interventions and antimicrobial stewardship programs should be implemented to enhance knowledge and adherence to guidelines, ultimately contributing to the containment of AMR.

1222. Impact of Microbiology Reporting Changes in Treatment of AmpC Bloodstream Infections

Abstract Background Recent literature suggests that AmpC production may be overcalled in Enterobacterales, leading to unnecessary broad-spectrum antimicrobial utilization. The Infectious Diseases Society of America (IDSA) has since reassessed classification of high and low risk organisms with inducible AmpC expression. With this updated guidance, our health system approved changes to our microbiology reporting of AmpC producers in an effort to guide prescribing of appropriate antibiotics. The primary objective of this project was to compare antibiotic prescribing patterns for high and low risk AmpC producers in patients with bloodstream infections (BSI) based on the addition of appended comments to antimicrobial susceptibility results. Methods This multicenter, retrospective, cohort study included patients with BSI from October 2022 to March 2023who received at least 48 hours of antimicrobial therapy for the following high and low risk AmpC producers: Citrobacter spp., Enterobacter spp., Klebsiella aerogenes, Serratia spp., Morganella spp., Providencia spp. The primary endpoint was the number of patients placed on optimal therapy based on adherence to the appended microbiology comment and IDSA guidance. Secondary endpoints included time to effective treatment, time to optimal treatment, duration of therapy, 30 day mortality, microbiological failure, microbiological relapse, 30 day readmission, length of stay, and hospital acquired Clostridioides difficile infection. Results A total of 191 positive blood cultures were identified with 93 patients (pre-appended comment = 57; post-appended comment = 36) meeting inclusion criteria. Patients were more likely to receive optimal therapy post-appended comment based on IDSA guidance for BSI (38.6% vs 72.2%, OR 4.14; 1.68-10.21). When stratified by high risk and low risk organism, the number of patients on optimal therapy increased in the post-appended comment group but was not statistically significant (high risk: 70.3% vs 88%, OR 3.08; 0.72-13.32; low risk: 10% vs 36.3%, 5.14; 0.92-28.50). No difference in secondary outcomes were detected. Conclusion Implementation of an appended microbiology note has the potential to have a positive impact on antimicrobial prescribing patterns in treatment of AmpC bloodstream infections.

Evaluation of Restricted Antimicrobial Utilization in a Tertiary Care Hospital

The World Health Organization has declared that antimicrobial resistance is one of the top ten public health threats faced by humanity. In addition to death and disability, prolonged illness results in longer hospital stays, more expensive medicines and financial challenges for those impacted. The emergence of antimicrobial resistance was mainly attributed to the inappropriate prescribing and overuse of antimicrobials including self-medication. The main objective of our study was to study the prescribing patterns of restricted antimicrobials among in-patients in a tertiary care hospital. A prospective observational study was conducted among 108 in-patients and the rationality of prescriptions with restricted antimicrobials was analyzed. There were 174 antimicrobials prescribed in 108 patients, out of 174 antimicrobials prescribed 140 drugs were restricted antimicrobials and 34 drugs were non-restricted antimicrobials. Among restricted antimicrobials prescribed 53(49.07%) were Penicillin and Beta-lactamase inhibitors, 40(37.03%) were Carbapenems, 30 (21.42%) were third-generation Cephalosporins, 7(6.48%) were Oxazolidinones,7(6.48%) were glycopeptide antibiotic and 2(1.85%) Vancomycin. Out of 108 patients, 16(14.81%) patients were prescribed antimicrobials for prophylactic use, 63(58.33%) patients were prescribed with antimicrobials based on empirical therapy and 29(26.85%) patients were prescribed antimicrobials based on culture and sensitivity reports. The study concluded that the restricted antimicrobials were mostly prescribed based on empirical therapy (58.33%) in the study population which shows the need to control the use of restricted antimicrobials.

Point Prevalence Survey of Antimicrobial Use and Resistance during the COVID-19 Era among Hospitals in Saudi Arabia and the Implications.

The inappropriate prescribing of antimicrobials increases antimicrobial resistance (AMR), which poses an appreciable threat to public health, increasing morbidity and mortality. Inappropriate antimicrobial prescribing includes their prescribing in patients hospitalized with COVID-19, despite limited evidence of bacterial infections or coinfections. Knowledge of current antimicrobial utilization in Saudi Arabia is currently limited. Consequently, the objective of this study was to document current antimicrobial prescribing patterns among Saudi hospitals during the COVID-19 pandemic. This study included patients with or without COVID-19 who were admitted to five hospitals in Makkah, Saudi Arabia. Data were gathered using the Global PPS methodology and analyzed using descriptive statistics. Out of 897 hospitalized patients, 518 were treated with antibiotics (57.7%), with an average of 1.9 antibiotics per patient. There were 174 culture reports collected, representing 36.5% of all cases. The most common indication for antibiotics use was community-acquired infections, accounting for 61.4% of all cases. 'Watch' antibiotics were the most commonly prescribed antibiotics, with the cephalosporins and carbapenems representing 38.7% of all antibiotics prescribed, followed by the penicillins (23.2%). Notably, Piperacillin/Tazobactam and Azithromycin were prescribed at relatively higher rates for COVID-19 patients. These findings highlight the need for continuous efforts to optimize the rational use of antibiotics through instigating appropriate antimicrobial stewardship programs in hospitals and, as a result, reduce AMR in the country.

Antimicrobial prescribing in a secondary care setting during the COVID-19 pandemic.

Increased antimicrobial resistance patterns lead to limited options for antimicrobial agents, affecting patient health and increasing hospital costs. To investigate the antimicrobial prescribing patterns at two district hospitals in Northern Ireland before and during the COVID-19 pandemic. A mixed prospective-retrospective study was designed to compare pre- and during pandemic antimicrobial prescribing data in both hospitals using a Global Point Prevalence Survey. Of the 591 patients surveyed in both hospitals, 43.8% were treated with 402 antimicrobials. A total of 82.8% of antimicrobial prescriptions were for empirical treatment. No significant difference existed in numbers of patients treated or antimicrobials used before and during the pandemic. There was a slight decrease of 3.3% in the compliance rate with hospital antimicrobial guidelines during the pandemic when compared with the pre-pandemic year of 2019, when it was 69.5%. Treatment based on patients' biomarker data also slightly decreased from 83.5% pre-pandemic (2019) to 81.5% during the pandemic (2021). There was no overall significant impact of the pandemic on the antimicrobial prescribing patterns in either hospital when compared with the pre-pandemic findings. The antimicrobial stewardship programmes would appear to have played an important role in controlling antimicrobial consumption during the pandemic.

Assessment of drug utilization pattern of antimicrobial agents in hospitalized patients with Infectious Diseases: A cross-sectional study in the United Arab Emirates.

Efficacious use of antimicrobial agents (AMAs) is paramount to combat a wide range of infections, ensure patient safety, and reduce antimicrobial resistance. To assess the drug utilization patterns of AMAs in hospitalized patients with infectious diseases in a secondary care hospital. A prospective observational study was conducted for 6 months in the internal medicine department. Data were collected, antimicrobial prescription patterns were screened, and drug utilization was assessed using the anatomical therapeutic chemical/defined daily dose methodology. Furthermore, predictors of the prescription of multiple AMAs were also analyzed. A total of 146 patient case records were reviewed and 285 AMAs were prescribed during the study period with a mean patient age of 54.2 ± 24.4 years. The average number of antimicrobials administered per patient was 1.94 ± 0.94. Respiratory tract infection and urinary tract infection were the common indications, and penicillins were the most prescribed class of AMAs. Multivariate analysis showed that the presence of comorbidities (P < 0.05) and longer hospital stays (P < 0.0001) increased the likelihood of prescribing multiple AMAs. The study provides insight into the pattern of prescribing of AMAs which help to improve the quality of care. Prescribing AMAs by generics and from the hospital formulary list according to the recommendations of the World Health Organization is a good sign of clinical practice. The study signifies the need to continuously monitor AMAs to optimize drug therapy and enhance the quality of drug use in clinical practice.

Point prevalence probing of antimicrobial prescription patterns from a developing country

ABSTRACT Background Irrational use of antibiotics intensifies resistance and jeopardizes advances made in modern medicine. We aimed to conduct a baseline gap analysis survey on antibiotic prescription practices across Pakistan. Research Design and Methods This multi-centered cross-sectional survey was conducted at six public sector tertiary care hospitals from February 2021 to March 2021. Data related to various variables including hospital infrastructure, policies and practices, monitoring and feedback, and epidemiological, clinical, and antibiotic prescription for surveyed patients was collected using World Health Organization (WHO) Point Prevalence Survey (PPS) methodology. Results In a survey of 837 inpatients, 78.5% were prescribed antibiotics. Most commonly prescribed antimicrobial was ceftriaxone (21.7%), followed by metronidazole (17.3%), cefoperazone-sulbactam (8.4%), amoxicillin-clavulanate (6.3%), and piperacillin/tazobactam (5.9%). Surgical prophylaxis (36.7%) and community-acquired infections (24.7%) were the main reasons for antibiotic prescriptions. Single antibiotics were given to 46.7% of patients, 39.9% received a combination of two antibiotics, and 12.5% were prescribed three or more antibiotics. Among six hospitals surveyed, two had drug and therapeutic committees, three had infection prevention and control committees, and one had an antibiotic formulary. Conclusion Findings demonstrate high consumption of broad-spectrum antimicrobials and emphasize the importance of expanding antimicrobial stewardship programs among hospitals. Mentoring clinical teams could help rationalize antimicrobial use.

Establishing obstetrics-specific metrics and interventions for antimicrobial stewardship.

To describe baseline antimicrobial stewardship (AMS) metrics and apply AMS interventions in an inpatient obstetrical population. From October 2018 to October 2019, our tertiary-care obstetrical center reviewed components of our AMS program, which included: (1) antimicrobial consumption data, (2) point prevalence surveys (PPS), and (3) prospective audit and feedback. We reviewed institutional data for antimicrobial consumption from the pharmacy database. Detailed point prevalence surveys were conducted for all antimicrobial prescriptions on two predefined dates each month. Daily audits and feedback assessed the appropriateness of all non-protocolized antimicrobials. Our average antimicrobial length of therapy (LOT) was 12 days per 100 patient-days, where erythromycin (2.33), amoxicillin (2.28), and ampicillin (1.81) were the greatest contributors. Point prevalence surveys revealed that 28.8% of obstetrical inpatients were on antimicrobials, of which 11.2% were inappropriate. Protocolized antimicrobials were 62% less likely (p = 0.027) to be inappropriate. From 565 audited prescriptions, 110 (19.5%) resulted in feedback, where 90% of recommendations were accepted and implemented. The most common reasons for interventions include incorrect dosage, recommending a diagnostic test before continuing antimicrobials, and changing antimicrobials based on specific culture and sensitivity. Antimicrobial use in obstetrics is unique compared to general inpatients. We provide a baseline set of metrics for AMS at our obstetrical center intending to lay the groundwork for AMS programming in our discipline. Antimicrobial protocolization, as well as audit and feedback, are feasible interventions to improve antimicrobial prescribing patterns.

Surgical site infection and antimicrobial prophylaxis prescribing profile, and its determinants among hospitalized patients in Northeast Ethiopia: a hospital based cross-sectional study

The inappropriate use of surgical antimicrobial prophylaxis is a common cause for increased risk of morbidity and mortality from surgical site infection in patients who underwent surgical procedures. The study aimed to evaluate surgical antimicrobial prophylaxis prescribing patterns, Surgical Site Infection (SSI), and its determinants in the surgical ward of Debre Berhan Comprehensive Specialized Hospital, northeast Ethiopia. A prospective cross-sectional study was conducted from October 1st 2022 to January 31st, 2023. Data collected from patient medical record cards and patient interviews were entered and analyzed using SPSS V26.0. The determinants of surgical site infection were determined from the multivariable logistic regression. P-value ≤ 0.05 was considered statistically significant. Ceftriaxone (70.5%) followed by a combination of ceftriaxone with metronidazole (21.90%) was the most frequently used prophylactic antibiotic. One hundred fifty-nine (78%) of patients were exposed to inappropriately used prophylactic antimicrobials and 62.2% of these were exposed to inappropriately selected antibiotics. One hundred twenty-six (61.9%) patients developed Surgical Site Infection (SSI). Duration of procedure longer than an hour and inappropriate use of antimicrobial prophylaxiswere the independent predictors for the occurrence of surgical site infections. Patients whose operation was lasted in longer than an hour were 3.39 times more likely to develop SSI compared to those whose operation was completed in less than an hour, AOR = 3.39 (95% CI: 1.24–9.30). Similarly, controlling the effect of other covariate variables, individuals who were given inappropriate antimicrobial prophylaxis were 6.67 times more likely to develop SSI compared to those given appropriate prophylaxis, AOR = 6.67 (95% CI: 1.05–42.49). The high rate of SSI requires due attention from clinicians as well as health policymakers. Duration of surgical procedure greater than an hour and inappropriate antimicrobial prophylaxis use was the independent predictor of surgical site infections.
