Antibiotic susceptibility patterns at the Médecins Sans Frontières (MSF) Acute Trauma Hospital in Aden, Yemen: a retrospective study from January 2018 to June 2021.

Antimicrobial resistance (AMR) is an urgent global health concern, especially in countries facing instability or conflicts, with compromised healthcare systems. Médecins Sans Frontières (MSF) established an acute trauma hospital in Aden, Yemen, treating mainly war-wounded civilians, and implemented an antimicrobial stewardship (AMS) programme. This study aimed to describe clinical characteristics and identify antibiotic susceptibility patterns representative of patients treated with antibiotics. Retrospective cross-sectional study using routinely collected data from all patients treated with antibiotics in the MSF-Aden Acute Trauma hospital between January 2018 and June 2021. Routine clinical data from patients' files was entered into an AMS electronic database and microbiological data were entered into WHONET. Both databases were imported and merged in REDCap and analysed using RStudio. Three hundred and sixty-three of 481 (75%) included patients were injured by violence-related trauma. Most were men aged 19-45 years (n = 331; 68.8%). In total, 598 infections were diagnosed and treated. MDR organisms were identified in 362 (60.5%) infections in 311 (65%) patients. Skin and soft-tissue infections (SSTIs) (n = 143; 24%) were the most common, followed by osteomyelitis (n = 125; 21%) and intra-abdominal-infections (IAIs) (n = 116; 19%), and 111 (19%) secondary bloodstream infections were identified. Escherichia coli was the most frequently identified pathogen, causing IAI (n = 87; 28%) and SSTI (n = 43; 16%), while Staphylococcus aureus caused mainly osteomyelitis (n = 84; 19%). Most Gram-negatives were ESBL producers, including E. coli (n = 193; 81.4%), Klebsiella pneumoniae (n = 72; 77.4%) and Enterobacter cloacae (n = 39; 50%) while most S. aureus were methicillin resistant (n = 93; 72.6%). High rates of MDR were found. This information will facilitate a comprehensive review of the empirical antibiotic treatment guidelines.

Evaluating Antibiotic Treatment Guideline Adherence to Ongoing Antibiotic Stewardship in a Tertiary Care Setting: A Retrospective Observational Study.

Antimicrobial resistance (AMR) is widely regarded as an increasing threat to global public health. Antibiotic treatment guidelines have been increasingly recognized as an effective tool to guide appropriate prescriptions and help curtail antibiotic resistance. The present study aimed to assess physician's adherence to hospital antibiotic treatment guideline recommendations in Nepal and determine predictive variables with a significant association. This was a retrospective, monocentric observational review to investigate the adherence to endorsed guidelines using the medical records of adults admitted to the hospital with a diagnosis of urinary tract infection (UTI), pneumonia, or skin and soft tissue infection (SSTI) from January 2018 to December 2019. Of the 2,077 medical records that were reviewed (954 UTI, 754 pneumonia, and 369 SSTI), 354 (17%) met the study inclusion criteria, which included 87 UTI, 180 pneumonia, and 87 SSTI patients. Among eligible patients with antibiotic prescriptions, the following were adherent to guideline recommendations: 33 (37.9%) UTI, 78 (43.3%) pneumonia, and 23 (26.4%) SSTI. The overall extent of adherence to hospital antibiotic treatment guidelines for the use of antibiotics among adult inpatients diagnosed with these common infections was 37.9%. Patients who received ceftriaxone (OR = 2.09, 95% CI = 1.18-3.71, p=0.012) and levofloxacin (OR = 4.63, 95% CI = 1.30-16.53, p=0.018) had significantly higher adherence to treatment guidelines. This study revealed a low adherence rate despite the availability of updated guidelines for antibiotic prescriptions. The findings confer an urgent need to confront antibiotic prescription patterns in such tertiary care centers for tailored interventions to improve adherence to antibiotic guidelines.

Antibiotic Guideline Adherence at the Emergency Department: A Descriptive Study from a Country with a Restrictive Antibiotic Policy.

Denmark has a low level of antimicrobial resistance (AMR). Patients hospitalized with suspected infection often present with unspecific symptoms. This challenges the physician between using narrow-spectrum antibiotics in accordance with guidelines or broad-spectrum antibiotics to compensate for diagnostic uncertainty. The aim of this study was to investigate adherence to a restrictive antibiotic guideline for the most common infection in emergency departments (EDs), namely community-acquired pneumonia (CAP). This multicenter descriptive cross-sectional study included adults admitted to Danish EDs with a suspected infection. Data were collected prospectively from medical records. We included 954 patients in the analysis. The most prescribed antibiotics were penicillin with beta-lactamase inhibitor at 4 h (307 (32.2%)), 48 h (289 (30.3%)), and day 5 after admission (218 (22.9%)). The empirical antibiotic treatment guidelines for CAP were followed for 126 (31.3%) of the CAP patients. At 4 h, antibiotics were administered intravenously to 244 (60.7%) of the CAP patients. At day 5, 218 (54.4%) received oral antibiotics. Adherence to CAP guidelines was poor. In a country with a restrictive antibiotic policy, infections are commonly treated with broad-spectrum antibiotics against recommendations.

The opinions of farm animal veterinarians in Ireland on antibiotic use and their role in antimicrobial stewardship

BackgroundAntibiotic use and resistance in animal production are a concern to public health, and there is an urgent need to reduce antibiotic use in farm animals. To prevent blame shifting, professionals from human medicine, animal medicine and environmental backgrounds must collaborate to tackle this issue. Veterinarians are typically responsible for overseeing and prescribing antibiotic use in animals. There are currently no available studies on the opinions of Irish farm animal veterinarians on antibiotic use, reduction opportunities and their relationships with farmers. A digital survey was developed and sent out to Irish farm animal veterinarians. This paper presents the results of a cross-sectional study of Irish farm animal veterinarians’ attitudes towards antimicrobial stewardship, their prescribing behaviours, antibiotic reduction opportunities and their attitudes for the future of antibiotic use. The veterinarian-farmer relationship is examined and potential interventions to reduce antibiotic use on farms are identified.ResultsIn total, 114 complete questionnaires were received, representing approximately 11 per cent of all farm animal veterinarians in Ireland. Respondents were aware of the problem of antibiotic resistance and recognise their role in the fight against it. They realise what actions they must take to reduce antibiotic use and identify barriers that prevent their farmer clients from implementing their advice. Many of them say that they can reduce antibiotic use on farms in the future, but some remain doubtful. There was no statistical difference between veterinarians that had less experience working than those that had more experience in their attitudes towards future reduction in antibiotic use.ConclusionMost of the respondents seek to use antibiotics as judiciously as they can. The majority agree that antibiotic overuse is the main contributor to antibiotic resistance. Possible solutions to reduce antibiotic use include the development of antibiotic treatment guidelines, assigning one unique practice to each farm and compulsory CPD (Continuous Professional Development) courses.

The impact of antibiotic stewardship interventions and patient related factors on antibiotic prescribing in a vascular surgical department

PurposeThe development of guidelines tailored to the departments’ needs and counselling during ward rounds are important antibiotic stewardship (AS) strategies. The aim was to analyse the impact of AS ward rounds and institutional guidelines as well as patient-related factors on antibiotic use in vascular surgical patients.MethodsA retrospective prescribing-analysis of 3 months (P1, P2) before and after implementing weekly AS ward rounds and antimicrobial treatment guidelines was performed. Choice of systemic antibiotics, days of antibiotic therapy and clinical data were obtained from electronic patient records.ResultsDuring P2, the overall antibiotic consumption as well as the use of last-resort compounds like linezolid and fluoroquinolones decreased distinctly (overall: 47.0 days of therapy (DOT)/100 patient days (PD) vs. 35.3 DOT/100PD, linezolid: 3.7 DOT/100PD vs. 1.0 DOT/100PD, fluoroquinolones: 7.0 DOT/100PD vs. 3.2 DOT/100PD) while narrow-spectrum beta-lactams increased by 48.4%. Courses of antibiotics were de-escalated more often during P2 (30.5% vs. 12.1%, p = 0.011). Only in P2, an antibiotic therapy was initiated in patients suffering from more comorbidities (i.e. higher Charlson Comorbidity Index) more frequently. Other patient factors had no distinct impact on antibiotic prescribing.ConclusionWeekly AS ward rounds improved adherence to institutional antibiotic treatment guidelines and antibiotic prescribing in vascular surgical patients. Clear patient-related determinants affecting choice of antibiotic therapies could not be identified.

Identification of provider and patient characteristics associated with antibiotic prescription in treatment of acute sinusitis.

Inappropriate antibiotic use contributes to the development of antibiotic resistance. Sinusitis is the fifth most common diagnosis responsible for antibiotic use. Appropriate antibiotic prescribing for acute sinusitis treatment is crucial to mitigate antibiotic resistance threats. The purpose of this study was to identify patient and provider characteristics associated with antibiotic prescription and to assess provider adherence to antibiotic prescribing guidelines for acute sinusitis treatment. Retrospective chart review including acute sinusitis cases diagnosed over 12 months, at two express care clinics in the Southwestern United States. Data extraction identified 371 cases meeting inclusion criteria (age >18 years). Descriptive statistical data analyses included Chi square test. A majority of cases received antibiotic prescriptions (90.8%, n = 337). Sociodemographic characteristics significantly associated with antibiotic prescription (p < .05) included race, ethnicity, insurance type, and smoking status. Patient-reported nature of symptoms, sinus tenderness, and erythema/edema nasal turbinates were also significantly associated with antibiotic prescription (p < .05). Antibiotic prescription and watchful waiting for acute sinusitis treatment were significantly associated with provider types (p < .05). A gap exists between current guidelines and clinical practice for acute sinusitis treatment in outpatient settings. Antibiotic prescription occurred, although not indicated, along with incorrect antibiotic choice, dose, and duration of therapy. Outpatient antimicrobial stewardship programs for acute sinusitis treatment with a focus on educational interventions for providers may reduce antibiotic overprescribing for acute sinusitis.

Antimicrobial susceptibility of bacterial isolates from clinical specimens in four Pacific Island countries, 2017–2021

There are limited antimicrobial resistance (AMR) surveillance data from low- and middle-income countries, especially from the Pacific Islands region. AMR surveillance data is essential to inform strategies for AMR pathogen control. We performed a retrospective analysis of antimicrobial susceptibility results from the national microbiology laboratories of four Pacific Island countries - the Cook Islands, Kiribati, Samoa and Tonga - between 2017 and 2021. We focused on four bacteria that have been identified as 'Priority Pathogens' by the World Health Organization: Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa. Following deduplication, a total of 20,902 bacterial isolates was included in the analysis. The most common organism was E.coli (n=8455) followed by S.aureus (n=7830), K.pneumoniae (n=2689) and P.aeruginosa (n=1928). The prevalence of methicillin resistance among S.aureus isolates varied between countries, ranging from 8% to 26% in the Cook Islands and Kiribati, to 43% in both Samoa and Tonga. Ceftriaxone susceptibility remained high to moderate among E.coli (87%-94%) and K.pneumoniae (72%-90%), whereas amoxicillin+clavulanate susceptibility was low against these two organisms (50%-54% and 43%-61%, respectively). High susceptibility was observed for all anti-pseudomonal agents (83%-99%). Despite challenges, these Pacific Island laboratories were able to conduct AMR surveillance. These data provide valuable contemporary estimates of AMR prevalence, which will inform local antibiotic formularies, treatment guidelines, and national priorities for AMR policy.

Gaps in antimicrobial stewardship programmes in Asia: a survey of 10 countries.

To determine antimicrobial stewardship (AMS) programme practices in Asian secondary- and tertiary-care hospitals. AMS programme team members within 349 hospitals from 10 countries (Cambodia, India, Indonesia, Japan, Malaysia, Pakistan, the Philippines, Taiwan, Thailand and Vietnam) completed a questionnaire via a web-based survey link. The survey contained questions as to whether 12 core components deemed essential for AMS programmes were implemented. Overall, 47 (13.5%) hospitals fulfilled all core AMS programme components. There was a mean positive response rate (PRR) of 85.6% for the responding countries in relation to a formal hospital leadership statement of support for AMS activities, but this was not matched by budgeted financial support for AMS activities (mean PRR 57.1%). Mean PRRs were ≥80.0% for the core AMS team comprising a physician or other leader responsible for AMS activities, a pharmacist and infection control and microbiology personnel. Most hospitals had access to a timely and reliable microbiology service (mean PRR 90.4%). Facility-specific antibiotic treatment guidelines for common infections (mean PRR 78.7%) were in place more often than pre-authorization and/or prospective audit and feedback systems (mean PRR 66.5%). In terms of AMS monitoring and reporting, PRRs of monitoring specific antibiotic use, regularly publishing AMS outcome measures, and the existence of a hospital antibiogram were 75.1%, 64.4% and 77.9%, respectively. Most hospitals participating in this survey did not have AMS programmes fulfilling the requirements for gold standard AMS programmes in hospital settings. Urgent action is required to address AMS funding and resourcing deficits.

Maternal Colonization of Extended-spectrum beta-lactamase-producing Enterobacteriaceae during Preterm versus Term Deliveries: A Prospective Study

Maternal carriage of extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E), such as Escherichia coli and Klebsiella pneumoniae, can cause adverse sequelae during pregnancy. E. coli is the second most frequent cause of neonatal sepsis after Group B Streptococcus (GBS) and the most frequent cause in preterm infants. Preterm E. coli isolates have higher rates of ESBL-E phenotype. Clinical guidelines for antibiotic treatment during labor in maternal GBS colonization exist but no guidelines are available for maternal carriage of ESBL-E.

Development of the first edition of African treatment guidelines for common bacterial infections and syndromes.

Standard treatment guidelines (STGs) are an important tool for ensuring high quality clinical care and prudent antimicrobial use (AMU) and stewardship (AMS). In 2018, African Union (AU) member state representatives recognized the lack of STGs as a barrier to AMS at national and facility levels. Previous research reported that only 17 of 55 (31%) member states had STGs that provided disease- or pathogen-specific antimicrobial treatment recommendations, excluding those that covered only treatment of HIV, malaria, and tuberculosis). The Africa Centres for Disease Control and Prevention convened expert panels to develop first edition antibiotic treatment guidelines for priority infectious diseases and clinical syndromes for pediatric and adult patient populations in Africa. The purpose of the guidelines is to provide healthcare workers with treatment guidance by harmonising existing national STGs, filling gaps where existing STGs are not available, and serving as a model for future guidelines. Two expert panels of 28 total clinicians, pharmacists, and other relevant stakeholders from 14 AU member states representing each continental region convened to develop consensus treatment recommendations for select priority bacterial infections and clinical syndromes. In developing recommendations, the panels considered treatment recommendations from existing STGs, drug availability, clinical experience, and available antimicrobial resistance data. The guidelines underwent an external review process where clinical stakeholders who did not serve on either panel were invited to submit feedback prior to their publication. The guidelines provide empiric antibiotic therapy guidelines – including drug selection, route of administration, formulation, dosage, and therapy duration – and principles of stewardship for 28 bacterial infections or clinical syndromes. The first edition guidelines for the treatment of common infectious diseases and clinical syndromes in Africa aims to improve clinical treatment and antimicrobial stewardship and will serve as a template for future regional guidelines.

Surgical antibiotic prophylaxis administration practices.

SETTING:A referral hospital in Kavre, Nepal.OBJECTIVES:To assess 1) compliance with National Antibiotic Treatment Guidelines (NATG), specifically, whether the administration of surgical antibiotic prophylaxis (SAP) (initial dosing and redosing) was in compliance with NATG for patients who were and were not eligible, and 2) development of surgical site infections (SSIs) among patients who underwent surgery in the Department of General Surgery (July–December 2019).DESIGN:This was a retrospective cohort analysis.RESULTS:The analysis included 846 patients, of which 717 (85%) patients were eligible for SAP and 129 (15%) were ineligible. Of those eligible, 708 (99%) received the initial dose; while 65 (50%) of the ineligible did not receive any dose. Of those who received the initial dose, 164 (23%) were eligible for redosing. Of these, only 23 (14%) received at least one redosing and 141 (86%) did not receive it. Overall compliance with NATG was achieved in 75% (632/846) of patients. SSIs occurred in 23 (3%) patients, 8 (35%) of whom did not have SAP administered according to NATG.CONCLUSION:A relatively high overall compliance with NATG for SAP administration was reported. Recommendations were made to improve compliance among those who were ineligible for SAP and those who were eligible for redosing.

Improving Antibiotic Stewardship in Acute Appendicitis through Risk-Based Empiric Treatment Selection.

Background: Empiric antimicrobial treatment selection for management of appendicitis is based on patient risk of infection with drug-resistant pathogens. Per Surgical Infection Society (SIS) guidelines, only high-risk patients should receive extended spectrum antibiotics. After observing substantial use of piperacillin-tazobactam at an academic medical center, a quality improvement initiative was developed targeting standardization of antibiotics for uncomplicated appendicitis. Patients and Methods: A project was performed to improve antibiotic stewardship in acute appendicitis treatment using plan-do-study-act methodology. We designed educational materials to guide risk-based empiric antimicrobial treatment selection for adult patients presenting with appendicitis. Implementation began January 1, 2020. High-risk criteria included presence of sepsis, presence of one or more comorbidities, and health-care-associated appendicitis. Retrospective chart review included adult patients admitted for appendectomy between January 1, 2019 and December 1, 2020. Pre-/post-implementation analysis and run chart analysis were performed. Primary outcome was the proportion of patients receiving the correct antibiotic. Secondary outcomes included antibiotic cost. Patients treated pre-/post-implementation were compared using univariable analysis, with statistical significance set at p < 0.05. Results: Of the 138 patients, 85 patients were in the pre-implementation group and 53 in the implementation group. The implementation group was 19.1% more likely to receive the correct antibiotic (pre = 31.8%; post = 50.9%; p = 0.03). Average cost per patient was reduced $13.25 (pre = $23.68 ± $18.76; post = $10.43 ± $8.45; p ≤ 0.0001). There were no differences in complications (pre = 2.4%; post = 0%; p = 0.26) or re-admissions (pre = 2.34%; post = 1.9%; p = 0.86). Conclusions: After an educational initiative to raise awareness about SIS guidelines for empiric antibiotic treatment for acute appendicitis, we observed an increase in the number of patients receiving the appropriate antibiotic. Prescribing habits were altered with no adverse impact on clinical outcomes. The next phase will address sustainability by incorporating an electronic medical record order set to integrate just-in-time education within the provider workflow.

Rational use of antimicrobials during COVID-19 times in Peru: role of antimicrobial stewardship programs and interventions in terms of infection control

Antimicrobial resistance (AMR) is an additional slow-evolving pandemic that precedes the COVID-19 pandemic and will continue when it ends. However, in countries such as Peru where there is high consumption and inadequate prescription of antibiotics, a more challenging future scenario can be expected. Antimicrobial Stewardship Programs (ASP) are multidisciplinary teams of professionals that aim to contain the emergence of multidrug-resistant organisms through strategies such as audit of antibiotic prescription or creating antibiotic treatment guidelines based on local AMR rates. The difficulty in the timely diagnosis of co-infections or superinfections in the clinical course of COVID-19 leads to inappropriate use of antibiotics, forcing ASP to adapt their strategies in this changing scenario. In Latin America, ASP not only has to promote behavior change in antibiotic prescribers but also fight the epidemic of false information (infodemia) and disinformation campaigns on COVID-19. Furthermore, poor-quality infection prevention and control principles require evaluating strategies to mitigate the subsequent impact on the AMR.

Antibiotic resistance among major pathogens compared to hospital treatment guidelines and antibiotic use in Nordic hospitals 2010–2018

Background The Nordic countries have comparable nationwide antibiotic resistance surveillance systems and individual antibiotic stewardship programmes. The aim of this study was to assess antibiotic resistance among major pathogens in relation to practice guidelines for hospital antibiotic treatment and antibiotic use in Nordic countries 2010–2018. Methods Antibiotic resistance among invasive isolates from 2010–2018 and aggregated antibiotic use were obtained from the European Centre for Disease Prevention and Control. Hospital practice guidelines were obtained from national or regional guidelines. Results Antibiotic resistance levels among Escherichia coli and Klebsiella pneumoniae were similar in all Nordic countries in 2018 and low compared to the European mean. Guidelines for acute pyelonephritis varied; 2nd generation cephalosporin (Finland), 3rd generation cephalosporins (Sweden, Norway), ampicillin with an aminoglycoside or aminoglycoside monotherapy (Denmark, Iceland and Norway). Corresponding guidelines for sepsis of unknown origin were 2nd (Finland) or 3rd (Sweden, Norway, Iceland) generation cephalosporins, carbapenems, (Sweden) combinations of penicillin with an aminoglycoside (Norway, Denmark), or piperacillin-tazobactam (all Nordic countries). Methicillin-resistant Staphylococcus aureus rates were 0–2% and empirical treatment with anti-MRSA antibiotics was not recommended in any country. Rates of penicillin non-susceptibility among Streptococcus pneumoniae were low (<10%) except in Finland and Iceland (<15%), but benzylpenicillin was recommended for community-acquired pneumonia in all countries. Conclusion Despite similar resistance rates among Enterobacteriaceae there were differences in practice guidelines for pyelonephritis and sepsis. National surveillance of antibiotic resistance can be used for comparison and optimization of guidelines and stewardship interventions to preserve the low levels of antibiotic resistance in Nordic countries.

Assessment of adherence to pneumonia guidelines and its determinants in an ambulatory care clinic in Ghana: findings and implications for the future.

BackgroundAdherence to local standard guidelines is seen as a pragmatic way to measure and improve the quality of future prescribing in ambulatory care to reduce morbidity, mortality and healthcare costs.ObjectivesTo evaluate adherence to the Ghana Standard Treatment Guidelines (STGs) for the empirical antibiotic treatment of ambulatory care patients with community-acquired pneumonia (CAP) in a region in Ghana and factors associated with it.MethodsA cross-sectional survey was conducted using a checklist to collect data from the hospital electronic database, which included sociodemographic details, payment type and clinical information of all ambulatory patients attending Keta Municipal Hospital, diagnosed and managed for CAP from September 2018 to January 2019. Prescriptions were assessed for adherence to the Ghana STG based on choice of antibiotics. A χ2 test and multiple logistic regression were subsequently conducted.ResultsA total of 1929 patient records with diagnosis of CAP within the study period at the ambulatory clinic were identified. The overall rate of adherence to the Ghana STG was 32.50% (n = 627). From the patient records collected, 62.50% were female, 41.84% were children (0–12 years), and 97.15% had a valid national health insurance status. Adherence was associated with the duration of antibiotic prescribing, number of additional antibiotics prescribed and some patients’ clinical characteristics.ConclusionsThe rate of adherence to Ghana STG among the study population was low. Efforts must be made to train and encourage prescribers to follow empirical guidelines to reduce inappropriate selection of antibiotics in the ambulatory care settings.

Factors that influence adherence to surgical antimicrobial prophylaxis (SAP) guidelines: a systematic review

BackgroundDespite the extensive research that has been conducted to date, practice often differs from established guidelines and will vary between individuals and organisations. It has been noted that the global uptake of local and international surgical antimicrobial prophylaxis (SAP) guidelines is poor with limited research investigating factors that affect guideline adherence. The purpose of this systematic review was to determine the reported barriers and enablers to the adherence of SAP guidelines.MethodsA search of the literature was performed using four electronic databases (CINAHL, EMBASE, PubMed and SCOPUS) for articles published in the English language from January 1998 to December 2018. Articles were included if they were solely related to SAP and discussed the barriers or enablers to SAP guideline adherence. Articles that assessed the adherence to a range of infection control measures or discussed adherence to antibiotic treatment guidelines rather than SAP guidelines were excluded from this review. Barriers and enablers were mapped to the Theoretical Domains Framework (TDF). The Mixed Methods Appraisal Tool was used to assess the quality of included studies.ResultsA total of 1489 papers were originally retrieved, with 48 papers meeting the eligibility criteria. Barriers and enablers were mapped to 11 out of 14 TDF domains: knowledge, skills, social/professional role and identity, beliefs about capabilities, beliefs about consequences, reinforcement, memory, attention and decision processes, environmental context and resources, social influences, emotion and behavioural regulation. Barriers were further categorised into personal or organisational barriers, while enablers were arranged under commonly trialled interventions.ConclusionsThere are numerous factors that can determine the uptake of SAP guidelines. An identification and understanding of these factors at a local level is required to develop tailored interventions to enhance guideline adherence. Interventions, when used in combination, can be considered as a means of improving guideline use.

Low Adherence to Recommended Guidelines for Open Fracture Antibiotic Prophylaxis.

Prompt administration of antibiotics is a critical component of open fracture treatment. Traditional antibiotic recommendations have been a first-generation cephalosporin for Gustilo Type-I and Type-II open fractures, with the addition of an aminoglycoside for Type-III fractures and penicillin for soil contamination. However, concerns over changing bacterial patterns and the side effects of aminoglycosides have led to interest in other regimens. The purpose of the present study was to describe the adherence to current prophylactic antibiotic guidelines. We evaluated the antibiotic-prescribing practices of 24 centers in the U.S. and Canada that were participating in 2 randomized controlled trials of skin-preparation solutions for open fractures. A total of 1,234 patients were evaluated. All patients received antibiotics on the day of admission. The most commonly prescribed antibiotic regimen was cefazolin monotherapy (53.6%). Among patients with Type-I and Type-II fractures, there was 61.1% compliance with cefazolin monotherapy. In contrast, only 17.2% of patients with Type-III fractures received the recommended cefazolin and aminoglycoside therapy, with an additional 6.7% receiving piperacillin/tazobactam. There is moderate adherence to the traditional antibiotic treatment guidelines for Gustilo Type-I and Type-II fractures and low adherence for Type-III fractures. Given the divergence between current practice patterns and prior recommendations, high-quality studies are needed to determine the most appropriate prophylactic protocol.
