Antimicrobial Use In Hospitals Research Articles

Analysis of antimicrobial drug usage in psychiatric specialized hospitals during the pandemic in China

ABSTRACT Background This study aims to compare antimicrobial drug usage in our hospital to Jiangsu Province and China from 2020 to 2022. Research design and methods A detailed analysis was performed using data from the National Antimicrobial Drug Clinical Application Monitoring Network. Several parameters were studied: the rate of antimicrobial drug use, number and types of drugs used, the rate of combined use, rate of microbiological examinations, drug use intensity, and cumulative Defined Daily Doses (DDDs). Results From 2020 to 2022, our hospital’s antimicrobial drug usage rate was consistently lower than Jiangsu Province and China. The average number of drug types and the combined drug use rate were higher in 2020 but fell below those in Jiangsu Province and China in 2021 and 2022. Our microbiological examination rate consistently surpassed that of Jiangsu Province and China. Furthermore, our Antimicrobial Usage Density and cumulative DDDs were notably lower. While AUD remained stable, DDDs showed a decreasing trend. The most dominant drug in DDDs was cefditoren, a third-generation cephalosporin. Conclusions During the pandemic years, our hospital not only met the requirements for antimicrobial drug usage, microbiological examination, AUD, and cumulative DDDs but also demonstrated a consistent year-by-year decrease in drug usage and DDDs.

Methicillin-resistant coagulase-positive staphylococci in new, middle-aged, and old veterinary hospitals in southern Thailand: A preliminary study.

Methicillin-resistant coagulase-positive staphylococci (MRCoPS) cause pyoderma, dermatitis, and nosocomial infection. Numerous factors, including indiscriminate antimicrobial use (AMU) in veterinary medicine, cleaning practices, and AMU in hospitals, contribute to MRCoPS. However, the relationship between hospital age and MRCoPS has not yet been investigated. This study aimed to estimate the prevalence of MRCoPS in the treatment and operation rooms of new, middle-aged, and old veterinary hospitals. Samples were collected from small animal hospitals in Surat Thani, Nakhon Si Thammarat, and Songkhla in Thailand. Hospitals were defined as those that had been in operation for 5 years (new, n = 5), 5-15 years (middle-aged, n = 6), or >15 years (old, n = 3). Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry was used to identify 280 samples, and duplex polymerase chain reaction was used to identify resistance genes (mecA and blaZ). The VITEK2® automated system was then used to determine the minimum inhibitory concentration. A total of 57 Staphylococcus species were identified and classified as coagulase-positive staphylococci (CoPS) (22/57, 38.60%) or coagulase-negative staphylococci (35/57, 61.40%), respectively. Nine of the 22 CoPS (40.90%) harbored the mecA gene, and 21 isolates (95.45%) harbored the blaZ gene. Interestingly, more MRCoPS was found in new hospitals (six isolates) than in middle-aged (one isolate) and old hospitals (two isolates), although there was no statistically significant difference in the presence of MRCoPS across new, middle-aged, and old veterinary hospitals (p = 0.095), Kruskal-Wallis test. There is a need for further detailed studies, including an increase in the number of hospitals in various locations. MRCoPS is a nosocomial pathogen that causes zoonotic and recurrent infections in veterinary hospitals. The prevalence of MRCoPS tended to be higher in new hospitals. Areas with heavy animal contact, such as hospital floors, are areas of particular concern, and cleaning/disinfection of these areas must be highlighted in hygiene regimens.

Development of quality indicators for antimicrobial stewardship in Belgian hospitals: a RAND – modified Delphi procedure

ABSTRACT Introduction Inappropriate antibiotic use is a major cause of antibiotic resistance. Therefore, optimizing antibiotic usage is essential. In Belgium, optimization of antimicrobials for the fight against multidrug resistant organisms (MDROs) is followed up by national surveillance by public health authorities. To improve appropriate antimicrobial use in hospitals, an effective national Antimicrobial Stewardship (AMS) program should include indicators for measuring both the quantity and quality of antibiotic use. Objectives The aim of this study was to develop a set of process quality indicators (QIs) to evaluate and improve AMS in hospitals. Methods A RAND-modified Delphi procedure was used. The procedure consisted of a structured narrative literature review to select the QIs, followed by two online questionnaires and an intermediate multidisciplinary panel discussion with experts in infectious diseases from general and teaching hospitals in Belgium. Results A total of 38 QIs were selected after the RAND-modified Delphi procedure, from which 11 QIs were selected unanimously. These QIs address compliancy of antibiotic therapy and prophylaxis with local guidelines, documentation of the rationale for antibiotic treatment in the medical record, the availability of AMS Programs and Outpatient Parenteral Antibiotic Therapy, resistance patterns and antimicrobial prescribing during focused ward rounds. Conclusion Our study selected 38 relevant process QIs, from which 11 were unanimously selected. The QIs can contribute to the improvement of quality of antibiotic use by stimulating hospitals to present better outcomes and by providing a focus on how to intervene and to improve prescribing of antimicrobials.

PAUSATE Study: Prevalence and appropriateness of the use of antimicrobials in Spanish hospitals

ObjectiveTo determine the prevalence and appropriateness of antimicrobial use in Spanish hospitals through a pharmacist-led systematic cross-sectional review. MethodA nationwide multicenter cross-sectional study was conducted on 10% of the patients admitted to the participating hospitals on one day in April 2021. Hospital participation was voluntary, and the population was randomly selected. The study sample was made up of patients who, on the day of the study, received at least one antimicrobial belonging to groups J01, J02, J04, J05AB, J05AD or J05AH in the Anatomical Therapeutic Chemical Classification System. The pharmacist in charge made a record and carried out an evaluation of the appropriateness of antimicrobial use following a method proposed and validated by the Pharmaceutical Care of Patients with Infectious Diseases Working Group of the Spanish Society of Hospital Pharmacy. The evaluation method considered each of the items comprising antimicrobial prescriptions. An algorithm was used to assess prescriptions as appropriate, suboptimal, inappropriate and unevaluable. ResultsOne-hundred three hospitals participated in the study and the treatment of 3,568 patients was reviewed. A total of 1,498 (42.0%) patients received antimicrobial therapy, 424 (28.3%) of them in combination therapy. The most commonly prescribed antimicrobials were amoxicillin-clavulanic acid (7.2%), ceftriaxone (6.4%), piperacillin-tazobactam (5.8%), and meropenem 4.0%. As regards appropriateness, prescriptions were considered appropriate in 34% of cases, suboptimal in 45%, inappropriate in 19% and unevaluable in 2%. The items that most influenced the assessment of a prescription as suboptimal were completeness of medical record entries, choice of agent, duration of treatment and monitoring of efficacy and safety. The item that most influences the assessment of a prescription as inappropriate was the indication of antimicrobial agent. ConclusionsThe method used provided information on the prevalence and appropriateness of the use of antimicrobials, a preliminary step in the design and implementation of actions aimed at measuring the impact of the use of antimicrobials within the antimicrobial stewardship programs.

National point-prevalence survey of healthcare-associated infections and antimicrobial use: UK-PAS/UKHSA joint call to action for all paediatric services.

The negative impact of high antimicrobial use (AMU), antimicrobial resistance and healthcare-associated infections (HCAIs) on children is concerning. However, a lack of available paediatric data makes it challenging to design and implement interventions that would improve health outcomes in this population, and impedes efforts to secure additional resources. The upcoming 2023 national point-prevalence survey of HCAIs and AMU in hospitals, led by the UK Health Security Agency, is an opportunity to collect valuable information, which will enable healthcare providers and policy makers to optimize antimicrobial stewardship and infection prevention practices in all populations, including children. These data will facilitate benchmarking and sharing of best practice, internally, nationally and internationally. This is a joint call to action asking all healthcare professionals-particularly in paediatrics-to nominate a lead for their institution and participate in this survey, to ensure appropriate paediatric representation, and help protect children from these growing threats.

Kentucky Antimicrobial Stewardship Innovation Consortium (KASIC): A Program to Improve Antibiotic Use in the Commonwealth

Antimicrobial resistance is a significant threat to modern healthcare and is driven by antimicrobial overuse. Hospital antimicrobial use in Kentucky exceeds national rates and long-term care facility antimicrobial stewardship implementation is low. Partnering with the Kentucky Department for Public Health, the Kentucky Antimicrobial Stewardship Innovation Consortium (KASIC) was created to facilitate antimicrobial stewardship across the Commonwealth of Kentucky. This manuscript describes KASIC objectives, defines the KASIC target audience, and describes KASIC methods

Intravenous to Oral Antibiotic Switch Therapy Among Patients Hospitalized With Community-Acquired Pneumonia.

Community-acquired pneumonia (CAP) is a leading cause of hospital admissions and antimicrobial use. Clinical practice guidelines recommend switching from intravenous (IV) to oral antibiotics once patients are clinically stable. We conducted a retrospective cohort study of adults admitted with CAP and initially treated with IV antibiotics at 642 US hospitals from 2010 through 2015. Switching was defined as discontinuation of IV and initiation of oral antibiotics without interrupting therapy. Patients switched by hospital day 3 were considered early switchers. We compared length of stay (LOS), in-hospital 14-day mortality, late deterioration (intensive care unit [ICU] transfer), and hospital costs between early switchers and others, controlling for hospital characteristics, patient demographics, comorbidities, initial treatments, and predicted mortality. Of 378 041 CAP patients, 21 784 (6%) were switched early, most frequently to fluoroquinolones. Patients switched early had fewer days on IV antibiotics, shorter duration of inpatient antibiotic treatment, shorter LOS, and lower hospitalization costs, but no significant excesses in 14-day in-hospital mortality or late ICU admission. Patients at a higher mortality risk were less likely to be switched. However, even in hospitals with relatively high switch rates, <15% of very low-risk patients were switched early. Although early switching was not associated with worse outcomes and was associated with shorter LOS and fewer days on antibiotics, it occurred infrequently. Even in hospitals with high switch rates, <15% of very low-risk patients were switched early. Our findings suggest that many more patients could be switched early without compromising outcomes.

Point Prevalence Survey of Antimicrobial Use during the COVID-19 Pandemic among Different Hospitals in Pakistan: Findings and Implications.

The COVID-19 pandemic has significantly influenced antimicrobial use in hospitals, raising concerns regarding increased antimicrobial resistance (AMR) through their overuse. The objective of this study was to assess patterns of antimicrobial prescribing during the current COVID-19 pandemic among hospitals in Pakistan, including the prevalence of COVID-19. A point prevalence survey (PPS) was performed among 11 different hospitals from November 2020 to January 2021. The study included all hospitalized patients receiving an antibiotic on the day of the PPS. The Global-PPS web-based application was used for data entry and analysis. Out of 1024 hospitalized patients, 662 (64.64%) received antimicrobials. The top three most common indications for antimicrobial use were pneumonia (13.3%), central nervous system infections (10.4%) and gastrointestinal indications (10.4%). Ceftriaxone (26.6%), metronidazole (9.7%) and vancomycin (7.9%) were the top three most commonly prescribed antimicrobials among surveyed patients, with the majority of antibiotics administered empirically (97.9%). Most antimicrobials for surgical prophylaxis were given for more than one day, which is a concern. Overall, a high percentage of antimicrobial use, including broad-spectrums, was seen among the different hospitals in Pakistan during the current COVID-19 pandemic. Multifaceted interventions are needed to enhance rational antimicrobial prescribing including limiting their prescribing post-operatively for surgical prophylaxis.

879. Intravenous to Oral Antibiotic Switch in Patients Hospitalized with Community-Acquired Pneumonia

Abstract Background Community-acquired pneumonia (CAP) is a leading cause of hospital admissions and antimicrobial use worldwide. The ATS/IDSA guidelines recommend switching antimicrobials to per-oral once patients are clinically stable. Using a large national inpatient database, we assessed switch therapy practices across hospitals and their associations with outcomes in patients hospitalized with CAP. Methods We included adult patients admitted with CAP and initially treated with intravenous (IV) antibiotics at 642 US hospitals from 2010–2015. Switching was defined as discontinuation of IV antibiotics and starting oral antibiotics without delay. Patients switched on or before hospital day 3 were considered early switchers. We conducted subgroup analysis restricted to patients initially treated with either 3rd generation cephalosporin/macrolide or quinolone monotherapy, indicating non-severe inpatient CAP. In a propensity-adjusted analysis, we compared length-of-stay (LOS), in-hospital 14-day mortality, late deterioration (ICU transfer), hospital costs, total antibiotic days, and C.difficile infection between early switchers and others. We also compared adjusted outcomes across hospital switching rate quartiles. Results Of 378,041 CAP patients, 116,118 (31%) were switched to oral antibiotics before discharge, and 21,784 (6%) were switched early. Hospital rates of early switching ranged from 3%-47%. Figure 1 summarizes the estimated effects of early switching among patients initially treated with cephalosporins/macrolide or quinolone monotherapy. Figure 2 shows the switch rate for patients within each hospital quartile, stratified by predicted mortality. Within each quartile, patients at higher predicted risk for mortality were less likely to be switched. Conclusion In this large multihospital cohort, most patients were not switched to oral antibiotics before discharge and &amp;lt; 6% were switched early. Early switching was not associated with worse outcomes and was positively associated with shorter LOS and total days on antibiotics. Patients at hospitals in the top quartile of early switch rates did not suffer worse outcomes and had shorter LOS and total antibiotic duration. Our findings suggest clinicians could switch more patients early without compromising outcomes.

Over-Prescription and Overuse of Antimicrobials in the Eastern Mediterranean Region: The Urgent Need for Antimicrobial Stewardship Programs with Access, Watch, and Reserve Adoption.

Excessive antimicrobial use contributes to the development of antimicrobial resistance. In the Eastern Mediterranean region (EMR), there is dearth of information on the prevalence of antimicrobial use in patients hospitalized in acute healthcare settings, clinical indications, types of antimicrobials prescribed, and quality indicators for prescriptions. Between September and December 2019, seven countries in the EMR conducted a standardized point prevalence survey. All patients present in the hospital wards at 8 a.m. on the day of the survey constituted the sample population. We collected data, including patient characteristics, antimicrobials received, therapeutic indication according to predefined lists, and markers of prescribing quality. The survey included data from 139 hospitals in seven countries. Among the 19,611 inpatients surveyed, 11,168 patients received at least one antimicrobial {crude prevalence: 56.9% (95%CI: 56.2-57.6%). The top three classes of antimicrobials prescribed were third-generation cephalosporins (26.7%), beta-lactam penicillins (18.1%), and imidazole derivatives (n = 1655, 9.8%). Carbapenems were most frequently prescribed for the treatment of healthcare-associated infections. Compliance with quality indicators of antimicrobial use was limited where treatment guidelines were available for 41% of antimicrobial prescriptions and targeted antimicrobial treatment represented 21% of therapeutic indications. Overall hospital antimicrobial use was high in countries of the EMR, pointing to the need to design and implement context-specific antimicrobial stewardship programs to optimize antimicrobial use and reduce antimicrobial resistance.

Exploring Antimicrobial Stewardship Influential Interventions on Improving Antibiotic Utilization in Outpatient and Inpatient Settings: A Systematic Review and Meta-Analysis.

Antimicrobial stewardship interventions are targeted efforts by healthcare organizations to optimize antimicrobial use in clinical practice. The study aimed to explore effective interventions in improving antimicrobial use in hospitals. Literature was systemically searched for interventional studies through PubMed, CINAHL, and Scopus databases that were published in the period between January 2010 to April 2022. A random-effects model was used to pool and evaluate data from eligible studies that reported antimicrobial stewardship (AMS) interventions in outpatient and inpatient settings. Pooled estimates presented as proportions and standardized mean differences. Forty-eight articles were included in this review: 32 in inpatient and 16 in outpatient settings. Seventeen interventions have been identified, and eight outcomes have been targeted. AMS interventions improved clinical, microbiological, and cost outcomes in most studies. When comparing non-intervention with intervention groups using meta-analysis, there was an insignificant reduction in length of stay (MD: −0.99; 95% CI: −2.38, 0.39) and a significant reduction in antibiotics’ days of therapy (MD: −2.73; 95% CI: −3.92, −1.54). There were noticeable reductions in readmissions, mortality rates, and antibiotic prescriptions post antimicrobial stewardship multi-disciplinary team (AMS-MDT) interventions. Studies that involved a pharmacist as part of the AMS-MDT showed more significant improvement in measured outcomes than the studies that did not involve a pharmacist.

Tipping the balance: A systematic review and meta-ethnography to unfold the complexity of surgical antimicrobial prescribing behavior in hospital settings

Surgical specialties account for a high proportion of antimicrobial use in hospitals, and misuse has been widely reported resulting in unnecessary patient harm and antimicrobial resistance. We aimed to synthesize qualitative studies on surgical antimicrobial prescribing behavior, in hospital settings, to explain how and why contextual factors act and interact to influence practice. Stakeholder engagement was integrated throughout to ensure consideration of varying interpretive repertoires and that the findings were clinically meaningful. The meta-ethnography followed the seven phases outlined by Noblit and Hare. Eight databases were systematically searched without date restrictions. Supplementary searches were performed including forwards and backwards citation chasing and contacting first authors of included papers to highlight further work. Following screening, 14 papers were included in the meta-ethnography. Repeated reading of this work enabled identification of 48 concepts and subsequently eight overarching concepts: hierarchy; fear drives action; deprioritized; convention trumps evidence; complex judgments; discontinuity of care; team dynamics; and practice environment. The overarching concepts interacted to varying degrees but there was no consensus among stakeholders regarding an order of importance. Further abstraction of the overarching concepts led to the development of a conceptual model and a line-of-argument synthesis, which posits that social and structural mediators influence individual complex antimicrobial judgements and currently skew practice towards increased and unnecessary antimicrobial use. Crucially, our model provides insights into how we might 'tip the balance' towards more evidence-based antimicrobial use. Currently, healthcare workers deploy antimicrobials across the surgical pathway as a safety net to allay fears, reduce uncertainty and risk, and to mitigate against personal blame. Our synthesis indicates that prescribing is unlikely to change until the social and structural mediators driving practice are addressed. Furthermore, it suggests that research specifically exploring the context for effective and sustainable quality improvement stewardship initiatives in surgery is now urgent.

Evaluation of trends in hospital antimicrobial use in the Lao PDR using repeated point-prevalence surveys-evidence to improve treatment guideline use

SummaryBackgroundAntimicrobial use (AMU) is a key driver of antimicrobial resistance (AMR). There are few data on AMU, to inform optimizing antibiotic stewardship, in the Lao PDR (Laos).MethodsPoint prevalence surveys (PPS) of AMU were conducted at four-month intervals in six general hospitals across Laos from 2017 to 2020, using modified Global-PPS data collection tools. The surveys focused on AMU amongst hospitalized inpatients.FindingsThe overall prevalence of inpatient AMU was 71% (4,377/6,188), varying by hospital and survey round from 50·4% (135/268) to 88·4% (61/69). Of 4,377 patients, 44% received >one antimicrobial. The total number of prescriptions assessed was 6,555. Ceftriaxone was the most commonly used (39·6%) antimicrobial, followed by metronidazole (17%) and gentamicin (10%). Pneumonia was the most common diagnosis among those prescribed antimicrobials in both children aged ≤5 years (29% among aged ≤1 year and 27% among aged >1 to ≤5years) and adults aged ≥15 years at 9%. The percentage of antimicrobial use compliant with local treatment guidelines was 26%; inappropriate use was mainly found for surgical prophylaxis (99%). Adult patients received ACCESS group antimicrobials less commonly than children (47% vs 63%, p-value<0·0001). Most WATCH group prescriptions (99%) were without a microbiological indication.InterpretationAMU among hospitalized patients in Laos is high with frequent inappropriate use of antimicrobials, especially as surgical prophylaxis. Continued monitoring and enhanced antimicrobial stewardship interventions are needed in Lao hospitals.FundingThe Wellcome Trust [Grant numbers 220211/Z/20/Z and 214207/Z/18/Z] and bioMérieux.

Development of the Korean Standardized Antimicrobial Administration Ratio as a Tool for Benchmarking Antimicrobial Use in Each Hospital.

BackgroundThe Korea National Antimicrobial Use Analysis System (KONAS), a benchmarking system for antimicrobial use in hospitals, provides Korean Standardized Antimicrobial Administration Ratio (K-SAAR) for benchmarking. This article describes K-SAAR predictive models to enhance the understanding of K-SAAR, an important benchmarking strategy for antimicrobial usage in KONAS.MethodsWe obtained medical insurance claims data for all hospitalized patients aged ≥ 28 days in all secondary and tertiary care hospitals in South Korea (n = 347) from January 2019 to December 2019 from the Health Insurance Review & Assessment Service. Modeling was performed to derive a prediction value for antimicrobial use in each institution, which corresponded to the denominator value for calculating K-SAAR. The prediction values of antimicrobial use were modeled separately for each category, for all inpatients and adult patients (aged ≥ 15 years), using stepwise negative binomial regression.ResultsThe final models for each antimicrobial category were adjusted for different significant risk factors. In the K-SAAR models of all aged patients as well as adult patients, most antimicrobial categories included the number of hospital beds and the number of operations as significant factors, while some antimicrobial categories included mean age for inpatients, hospital type, and the number of patients transferred from other hospitals as significant factors.ConclusionWe developed a model to predict antimicrobial use rates in Korean hospitals, and the model was used as the denominator of the K-SAAR.

Change in Antimicrobial Use During COVID-19 Pandemic in South Carolina Hospitals: A Multicenter Observational Cohort Study

ObjectivesThis retrospective cohort study examined the impact of the pandemic on antimicrobial use (AU) in South Carolina hospitals. MethodsAntimicrobial use in days of therapy (DOT) per 1000 days-present was evaluated in 17 hospitals in South Carolina. Matched-pairs mean difference was used to compare AU during the pandemic (March–June 2020) with that during the same months in 2019 in hospitals that did and did not admit patients with COVID-19. ResultsThere was a 6.6% increase in overall AU in the seven hospitals that admitted patients with COVID-19 (from 530.9 to 565.8; mean difference (MD) 34.9 DOT/1000 days-present; 95% CI 4.3, 65.6; P = 0.03). There was no significant change in overall AU in the remaining 10 hospitals that did not admit patients with COVID-19 (MD 6.0 DOT/1000 days-present; 95% CI –55.5, 67.6; P = 0.83). Most of the increase in AU in the seven hospitals that admitted patients with COVID-19 was observed in broad-spectrum antimicrobial agents. A 16.4% increase was observed in agents predominantly used for hospital-onset infections (from 122.3 to 142.5; MD 20.1 DOT/1000 days-present; 95% CI 11.1, 29.1; P = 0.002). There was also a 9.9% increase in the use of anti-methicillin-resistant Staphylococcus aureus (MRSA) agents (from 66.7 to 73.3; MD 6.6 DOT/1000 days-present; 95% CI 2.3, 10.8; P = 0.01). ConclusionThe COVID-19 pandemic appears to drive overall and broad-spectrum antimicrobial use in South Carolina hospitals admitting patients with COVID-19. Additional antimicrobial stewardship resources are needed to curtail excessive antimicrobial use in hospitals to prevent subsequent increases in antimicrobial resistance and Clostridioides difficile infection rates, given the continuing nature of the pandemic.

Impact of Generic Entry on Hospital Antimicrobial Use: A Retrospective Quasi-Experimental Interrupted Time Series Analysis

Background: The impact of antimicrobials generic entry (GE) is controversial. Their introduction could provide an economic benefit yet may also increase their consumption, leading to a higher risk of resistance. Our aim was to analyze the impact of GE on trends of antimicrobial consumption in an acute-care hospital. Methods: A retrospective quasi-experimental interrupted time series analysis was conducted at a 400-bed tertiary hospital in Barcelona, Spain. All antimicrobials for systemic use for which a generic product entered the hospital from January 2000 to December 2019 were included. Antimicrobial consumption was expressed as DDD/100 bed days. Results: After GE, the consumption of cefotaxime (0.09, p < 0.001), meropenem (0.54, p < 0.001), and piperacillin-tazobactam (0.13, p < 0.001) increased, whereas the use of clindamycin (−0.03, p < 0.001) and itraconazole (−0.02, p = 0.01) was reduced. An alarming rise in cefepime (0.004), daptomycin (1.02), and cloxacillin (0.05) prescriptions was observed, despite not achieving statistical significance. On the contrary, the use of amoxicillin (−0.07), ampicillin (−0.02), cefixime (−0.06), fluconazole (−0.13), imipenem–cilastatin (−0.50) and levofloxacin (−0.35) decreased. These effects were noticed beyond the first year post GE. Conclusions: GE led to an increase in the consumption of broad-spectrum molecules. The potential economic benefit of generic antibiotics could be diluted by an increase in resistance. Antimicrobial stewardship should continue to monitor these molecules despite GE.

Assessment of antimicrobial use in private and government hospitals, a comparative study in central kerala, using who indicators

Background: Irrational use of antimicrobial can cause various unwanted and untoward events. It may diminish the quality of patient care, increase the cost of therapy, and involvement in various side effects. Thus, the appropriateness of antimicrobial use in hospitals plays a pivotal role in patient safety. Objective: To analyze and assess the prescribing pattern of antimicrobials in private and government hospitals as per the WHO indicators. Methodology: A prospective comparative observational study was carried out for 6 months, with the patient diagnosed with an infectious disease admitted to the medical ward of both the hospitals during the study period. The data obtained from the study sites were Compared and analyzed using WHO indicators described in WHO’s “How to Investigate Antimicrobial use in Hospitals: Selected Indicators, Feb 2012”. Results: The study involved 216 patients and the average number of antimicrobials prescribed was found to be 1.73 in a private hospital and 2.07 in the government hospital, average cost of antimicrobials was found to be 86.48 INR in private and 31.04 INR in the government hospital, average duration of antimicrobial treatment was 4.8 in private and 5.2 in the government hospital, and the percentage of antimicrobials prescribed in generic was 33.33% in private and 87.83% in the government hospital. Considering the spectrum of antibiotics, both private (94.7%) and government (88.8%) used broad-spectrum antimicrobials. In both hospitals, cephalosporins were the most frequently prescribed class of antimicrobials. Comparing the dosage of antimicrobials given, injection usage is at the highest in government (59.5%) as well as in the private hospital (68.4%). Conclusion: This study indicates that the average cost of antimicrobials was more in a private hospital than that in a government hospital and other indicators such as the number of antimicrobials per hospitalization, duration of antimicrobial treatment, and the percentage of generic antimicrobials prescribed were all found to be more in a government hospital. In both private and government hospitals broad-spectrum antimicrobials were widely used, with cephalosporin as the most prescribed class.

A multicentre point prevalence study of antibiotics utilization in hospitalized patients in an urban secondary and a tertiary healthcare facilities in Nigeria: findings and implications

ABSTRACT Objectives The understanding of antimicrobial utilization patterns is pertinent to successful implementation of the National Action Plans on Antimicrobial Resistance (AMR). There is, however, limited information on antibiotics utilization in Nigeria. This study was undertaken to build on existing information and provide direction for appropriate interventions including Antibiotics Stewardship Programs (ASP). Method A Point Prevalence Study (PPS) was conducted in two public urban health facilities in Lagos, Nigeria using a design adapted from the European Center for Disease Prevention and Control (ECDC) and Global-PPS surveys. Results The prevalence of antibiotics use was 80.6% administered mostly parenterally (83.1% of total prescriptions) with concerns with extended surgical antibiotics prophylaxis. The mostly used antibiotics in the secondary hospital were parenteral metronidazole (32.4%), ceftriaxone (27.5%), and amoxicillin + clavulanate (8.2%) while the mostly used in the tertiary hospital were ceftriaxone (25.3%), parenteral metronidazole (19.1%), and amoxicillin + clavulanate (9.3%). There was an appreciable lack of specific functional capacities, policies, and processes to promote appropriate antimicrobial use in both hospitals. Conclusions There is high rate of antibiotics utilization in these facilities with lack of institutional frameworks and processes for ensuring appropriate antibiotic use. The study provides the information needed to improve future antimicrobial use in hospitals and reduce AMR.

Evaluation of Prescribing Patterns of Antibiotics Using Selected Indicators for Antimicrobial Use in Hospitals and the Access, Watch, Reserve (AWaRe) Classification by the World Health Organization

Antibiotic resistance poses a significant threat to the world, and irrational use of antibiotics is a major contributing factor. Evaluation of antimicrobial use is underway with the help of indicators and the World Health Organization (WHO) classification of antibiotics into Access, Watch, and Reserve (AWaRe) categories. We aimed to evaluate the prescribing pattern of antibiotics using the AWaRe classification by the WHO and selected indicators for antimicrobial use in hospitals. A total of 1.000 prescriptions were analyzed during the study for antibiotic prescribing patterns. Antibiotic consumption was calculated using defined daily dose (DDD) methodology. The prescribing pattern was evaluated using the WHO classification of antibiotics into the categories AWaRe and using selected indicators (hospital and prescribing) for antimicrobial use in hospitals. A total of 1.128 antibiotics were prescribed during the study. The 19-44 age group was prescribed a high number of antibiotics (n=510). Females were prescribed a high number of antibiotics compared with males (n=602). Azithromycin was the most commonly consumed antibiotic (14.97 DDD/1000/day). Four antibiotics from the Access category and five from the Watch category were prescribed in the study. The Watch category of antibiotics were consumed in a high number. There were no standard treatment guidelines in the hospital. In all, 98.0% of antibiotics were consistent with the hospital formulary and prescribed under generic names. The average number of antibiotics prescribed per patient was 1.12. The average duration of antimicrobial treatment was 5.24 days. The percentage of patients prescribed antimicrobials for pneumonia in accordance with treatment guidelines was 13.28%. Irrational use of antibiotics exists in hospitals. There is a need to maintain standard treatment guidelines in the hospital because it prevents irrational use of antibiotics.
