Evaluating antibiotic prophylaxis adherence: Implications for surgical site infections and wound care management

AimThis study aimed to evaluate adherence to an antibiotic prophylaxis protocol and its impact on incidence of surgical site infection (SSI). Materials and methodA prospective observational cohort study was conducted at a teaching hospital in São Paulo, Brazil, from September to November 2015. The population were adults who underwent surgery with surgical antibiotic prophylaxis. The main outcomes measured were incidence of SSI at 30-days postoperatively, protocol adherence and surgical wound complications. STROBE guidelines were followed. ResultsAmong the 527 participants recruited, a 30-day follow-up was completed by 78.7 % (n = 415). Within this cohort, 57.6 % were females aged over 60 years (36.4 %). The incidence of SSI stood at 9.4 % (n = 39), with dehiscence being the most prevalent complication at 64.1 % (n = 25), followed by increased exudate at 51.3 % (n = 20). Notably, full adherence to the antibiotic prophylaxis protocol was low at 1.7 % (n = 7). The study observed a 60 % increased risk of SSI for every protocol mistake made. Alarmingly, 17.8 % (n = 74) of participants received antibiotic treatment exceeding the stipulated protocol duration. The overall mortality rate stood at 13.5 % (n = 56), with 1 % (n = 4) of these deaths attributed to SSI. ConclusionThere is a pressing global necessity to enhance antibiotic management, as underscored by this study's revelation of low adherence to the antibiotic prophylaxis protocol. This lack of adherence correlated with a notable incidence of SSI and subsequent wound complications. Nearly 20 % of participants received prolonged antibiotic treatment. Adhering strictly to the protocol could substantially impact SSI-related outcomes and enhance global antibiotic management.

Analyzing the Efficacy of Metronidazole as Additional Surgical Site Infection Prophylaxis in Patients Undergoing Hysterectomy [ID 2683482

INTRODUCTION: The American College of Obstetricians and Gynecologists recommends cefazolin for antibiotic surgical prophylaxis for hysterectomy procedures. In 2018, hysterectomy surgical site infection (SSI) data at John Peter Smith Hospital demonstrated a higher proportion of anaerobic growth identified on cultures. The addition of metronidazole with cefazolin became surgical prophylaxis protocol at our institution. The purpose of the study is to compare rates of non-superficial SSI before and after the addition of metronidazole in hysterectomy procedures. METHODS: This was a retrospective cohort study of patients who underwent hysterectomy of any surgical approach from January 2015 to July 2023. The primary exposure of interest was administration of metronidazole with additional covariates including age, body mass index, diabetes, oncology status, and wound class. The association between metronidazole administration and non-superficial SSI was examined using a logistic regression model. Appropriate waiver was received from the institutional IRB. RESULTS: Two thousand five hundred thirty-four hysterectomies were included in our cohort. 1,207 (44%) cases had metronidazole administration, with 98% of those cases occurring after the antibiotic was incorporated into the protocol. Of the patients who did not receive metronidazole, 49 (3.7%) patients had a non-superficial SSI compared to 14 (1.2%) patients that had a non-superficial SSI with metronidazole administration. After adjusting for age and oncology status, patients who did not receive metronidazole had higher odds of having a SSI compared those who did (adjusted odds ratio [aOR]: 3.6; 95% CI: 1.97, 6.3; P≤.0001). CONCLUSION: The results demonstrate potential infection prevention benefit with metronidazole to patients undergoing hysterectomy, supporting the institutional prophylaxis protocol. The findings could have further implications across hospitals with similar patient populations.

Contribution of the patient microbiome to surgical site infection and antibiotic prophylaxis failure in spine surgery.

Despite modern antiseptic techniques, surgical site infection (SSI) remains a leading complication of surgery. However, the origins of SSI and the high rates of antimicrobial resistance observed in these infections are poorly understood. Using instrumented spine surgery as a model of clean (class I) skin incision, we prospectively sampled preoperative microbiomes and postoperative SSI isolates in a cohort of 204 patients. Combining multiple forms of genomic analysis, we correlated the identity, anatomic distribution, and antimicrobial resistance profiles of SSI pathogens with those of preoperative strains obtained from the patient skin microbiome. We found that 86% of SSIs, comprising a broad range of bacterial species, originated endogenously from preoperative strains, with no evidence of common source infection among a superset of 1610 patients. Most SSI isolates (59%) were resistant to the prophylactic antibiotic administered during surgery, and their resistance phenotypes correlated with the patient's preoperative resistome (P = 0.0002). These findings indicate the need for SSI prevention strategies tailored to the preoperative microbiome and resistome present in individual patients.

Surgical Antibiotic Prophylaxis Practices and Occurrence of Surgical Site Infections Among Operated Patients at Dodoma Regional Referral Hospital, Tanzania

This study was conducted to determine association between perioperative antibiotic prophylaxis practices and occurrence of surgical site infections at Dodoma Regional Referral Hospital in Tanzania. Surgical site infections (SSIs) are preventable complications following surgery, but still cause significant burden in terms of patient morbidity, mortality and increased cost of treatment. A prospective cohort study was conducted among 162 operated patients. Patients with different trends of antibiotic prophylaxis were followed up for occurrence SSIs. Analysis of data was done by SPSS version 20 program using frequency tables, chi square test, Kaplan-meier and Cox regression methods. Significance level of < 0.05 was taken to establish associations between variables. It was found that, 60.5% of patients received preoperative antibiotic prophylaxis, the overall surgical site infections rate was 14.8%. There was no significant difference in occurrence of surgical site infections between patients who received and those who did not receive preoperative antibiotic prophylaxis (p=0.88). The study concluded that SSIs are significant complications. Perioperative antibiotic prophylaxis is commonly practiced. Establishment of local protocol on antibiotic prophylaxis and adherence to infection prevention can improve the prevailing situation.

Antibioprophylaxie chirurgicale et medicale courte de l’enfant

Antibiotic prophylaxis aims to counteract bacterial proliferation in order to reduce the risk of infection in a patient. The emergence of multi-resistant bacteria, which can lead to therapeutic impasses, has prompted the international medical community to regularly propose programs to optimize the use of antibiotics. In collaboration with the SFAR (Société Française d'Anesthésie Réanimation), the GPIP has updated its recommendations for good practice in surgical antibiotic prophylaxis in children, and for short antibiotic prophylaxis in medicine. These recommendations provide a general framework based on the analysis of national and international data, and more often than not on expert opinion, and are intended to support the implementation of local antibiotic prophylaxis protocols specific to each team.

Candida spp. Deep Sternal Wound Infections: A Consequence of Antibiotic use?

A cluster of deep sternal wound infections caused by Candida spp. occurred at our institution. Investigation did not disclose a common environmental source. We postulate that broad-spectrum antibiotic surgical prophylaxis and liberal use of antibiotics contributed to these infections.

An overview of risk factors, management and prevention of cochlear implant infections.

With cochlear implantation becoming increasingly performed worldwide, an understanding of the risk factors, preventive measures, and management of cochlear implant (CI) infection remains important given the significant morbidity and cost it conveys. At the turn of the 21st century there was a decrease in rates of CI infection, particularly meningitis, following the discontinuation of positioner use for CI. However, in more recent years rates of CI infection have remained largely static. Recently, studies evaluating preventive measures such as pneumococcal vaccination, S. aureus decolonization and surgical antibiotic prophylaxis have emerged in the literature. Prompt recognition of CI infection and appropriate investigation and management are key, however at present treatment is largely informed by cohort and case-control studies and expert opinion. Preventive measures including pneumococcal vaccination, S. aureus decolonization and preoperative antibiotic prophylaxis play a role in reducing rates of CI infection. However, there remains a need for well designed clinical trials to provide higher level evidence to better guide preventive measures for, and management decisions of, CI infections in the future.

O162: A Surgically Led Quality Improvement Initiative in Surgical Antibiotic Prophylaxis (SAP): A One-year Review of Practice and Change in an Irish Context

Abstract Introduction Amongst growing concerns of antimicrobial resistance, surgical site infection (SSI) remains one of the most common healthcare associated infections. Optimal use of Surgical Antibiotic Prophylaxis (SAP) is critical. Quality Improvement (QI) in this area is often led by pharmacists or infection specialists. Methods A two-year, surgically led QI initiative was established in two Irish hospitals in July 2022. Baseline level of compliance with local guidelines with regard four aspects of SAP (indication, agent, timing, and duration) was audited. Change interventions aimed at specific aspects of compliance were trialled. Interventions included; guideline education for prescribers, process changes (editing the sign in/time out sheet) and the application of prescribing nudges (antibiotic duration sticker in post-operative drug chart). Results A total of 620 patient records were audited over one year. Pre-intervention compliance with all four aspects of SAP was observed in only 72/303 patients (23.7%). Educational interventions with surgical prescribers led to improved compliance with agent choice (43.5% (71/165) to 65.3% (94/144)). Education of anaesthetists showed improved timing of administration with 10.8% (14/129) of SAP administered post-incision post-intervention compared to 18.9% (21/111) pre-intervention. Application of the SAP duration sticker showed an overall decrease in mean SAP duration from 70.4 hours to 28.2 hours in those patients requiring more than a single SAP dose. Overall compliance levels have improved, thus far, from 23.7% to 39.8%. Conclusion Increasing compliance with SAP guidance is a challenge. A multi-faceted, institution specific, surgically led approach grounded in QI methodology shows promise.

Differences in microorganisms causing infection after cranial and spinal surgeries.

The primary aim of this retrospective study was to assess differences in the pathogens causing surgical site infections (SSIs) following craniectomies/craniotomies and open spinal surgery. The secondary aim was to assess differences in rates of SSI among these operative procedures. ANOVA tests with Bonferroni correction and incidence risk ratios (RRs) were used to identify differences in pathogens by surgical site and procedure using retrospective, de-identified records of 19,993 postneurosurgical patients treated between 2007 and 2020. The overall infection rates for craniotomy/craniectomy, laminectomy, and fusion were 2.1%, 1.1%, and 1.5%, respectively, and overall infection rates for cervical, thoracic, and lumbar spine surgery were 0.3%, 1.6%, and 1.9%, respectively. Craniotomy/craniectomy was more likely to result in an SSI than spine surgery (RR 1.8, 95% CI 1.4-2.2, p < 0.0001). Cutibacterium acnes (RR 24.2, 95% CI 7.3-80.0, p < 0.0001); coagulase-negative staphylococci (CoNS) (methicillin-susceptible CoNS: RR 2.9, 95% CI 1.6-5.4, p = 0.0006; methicillin-resistant CoNS: RR 5.6, 95% CI 1.4-22.3, p = 0.02); Klebsiella aerogenes (RR 6.5, 95% CI 1.7-25.1, p = 0.0003); Serratia marcescens (RR 2.4, 95% CI 1.1-7.1, p = 0.01); Enterobacter cloacae (RR 3.1, 95% CI 1.2-8.1, p = 0.02); and Candida albicans (RR 3.9, 95% CI 1.2-12.3, p = 0.02) were more commonly associated with craniotomy/craniectomy cases than fusion or laminectomy SSIs. Pseudomonas aeruginosa was more commonly associated with fusion SSIs than craniotomy SSIs (RR 4.4, 95% CI 1.3-14.8, p = 0.02), whereas Escherichia coli was nonsignificantly associated with fusion SSIs compared to craniotomy SSIs (RR 4.1, 95% CI 0.9-18.1, p = 0.06). Infections with E. coli and P. aeruginosa occurred primarily in the lumbar spine (p = 0.0003 and p = 0.0001, respectively). SSIs due to typical gastrointestinal or genitourinary gram-negative bacteria occur most commonly following lumbar surgery, particularly fusion, and are likely to be due to contamination of the surgical bed with microbial flora in the perianal area and genitourinary tract. Cutibacterium acnes in the skin flora of the head and neck increases risk of infection due to this microbe following surgical interventions in these body sites. The types of gram-negative bacteria associated with craniotomy/craniectomy SSIs suggest potential environmental sources of these pathogens. Based on the authors' findings, neurosurgeons should consider using a two-step skin preparation with benzoyl peroxide, in addition to a standard antiseptic such as alcoholic chlorhexidine for cranial, cervical, and upper thoracic surgeries. Additionally, broader gram-negative bacterial coverage, such as use of a third-generation cephalosporin, should be considered for lumbar/lumbosacral fusion surgical antibiotic prophylaxis.

Surgical Antibiotic Prophylaxis: A Proposal for a Global Evidence-Based Bundle.

In the multimodal strategy context, to implement healthcare-associated infection prevention, bundles are one of the most commonly used methods to adapt guidelines in the local context and transfer best practices into routine clinical care. One of the most important measures to prevent surgical site infections is surgical antibiotic prophylaxis (SAP). This narrative review aims to present a bundle for the correct SAP administration and evaluate the evidence supporting it. Surgical site infection (SSI) prevention guidelines published by the WHO, CDC, NICE, and SHEA/IDSA/APIC/AHA, and the clinical practice guidelines for SAP by ASHP/IDSA/SIS/SHEA, were reviewed. Subsequently, comprehensive searches were also conducted using the PubMed®/MEDLINE and Google Scholar databases, in order to identify further supporting evidence-based documentation. The bundle includes five different measures that may affect proper SAP administration. The measures included may be easily implemented in all hospitals worldwide and are based on minimal drug pharmacokinetics and pharmacodynamics knowledge, which all surgeons should know. Antibiotics for SAP should be prescribed for surgical procedures at high risk for SSIs, such as clean-contaminated and contaminated surgical procedures or for clean surgical procedures where SSIs, even if unlikely, may have devastating consequences, such as in procedures with prosthetic implants. SAP should generally be administered within 60 min before the surgical incision for most antibiotics (including cefazolin). SAP redosing is indicated for surgical procedures exceeding two antibiotic half-lives or for procedures significantly associated with blood loss. In principle, SAP should be discontinued after the surgical procedure. Hospital-based antimicrobial stewardship programmes can optimise the treatment of infections and reduce adverse events associated with antibiotics. In the context of a collaborative and interdisciplinary approach, it is essential to encourage an institutional safety culture in which surgeons are persuaded, rather than compelled, to respect antibiotic prescribing practices. In that context, the proposed bundle contains a set of evidence-based interventions for SAP administration. It is easy to apply, promotes collaboration, and includes measures that can be adequately followed and evaluated in all hospitals worldwide.

Factors Contributing to the Misuse of Antimicrobial Prophylaxis in Preventing Pediatric Surgical Site Infections

Surgical site infections (SSIs) can disturb the healthcare systems, patients, and their families. In the pediatric population, adequate preventive measures, including appropriate surgical antibiotic prophylaxis (SAP), are essential to avoid the social, economic, and health concerns related to these infections. To describe the causes of inappropriate usage of SAP among pediatric patients, we used two databases, PubMed and Google Scholar, to conduct this review. We also manually screened the references of the articles reporting SSIs and SAP. The included articles were related to microorganisms associated with pediatric SSIs, causes of inappropriate SAP, and recommendations to improve their use. We excluded articles published in languages other than English and those beyond the scope of our review. Common causative microorganisms of pediatric SSIs are bacteria, mainly Staphylococcus aureus, and fungi, mainly Candida albicans. The appropriate use of SAP was based on three aspects: time and duration of administration, dose, and chosen antibiotics. The unavailability of international guidelines and fear of infectious factors force healthcare providers to administer SAP inappropriately. Other factors were related to the type of surgical operation, surgical wound classification, and weight of pediatric patients. Continuing education on guidelines for using antibiotics correctly and support from healthcare institutions by adopting adequate preventive measures can help ensure the appropriate use of SAP.

Exploring Effective Alternatives to Beta-Lactam Antibiotics for Surgical Prophylaxis: A Comprehensive Investigation

Introduction: The significance of administering preventive antibiotics before a surgical procedure is firmly established,moreover the aim of antibiotic prophylaxis is to limit surgical site infections in surgical patients, based essentially on the use of betalactamines, Individuals with a beta-lactam allergy may experience adverse reactions to antibiotics within this class, such as penicillins and cephalosporins, it leeds to life-threatening symptoms that require immediate medical attention, the aim of our study is to evaluate the surgical antibiotic prophylaxis practices by our staff Material and methods: we carried out a survey using a questionnaire aimed at anesthesia-intensive care staff working in different operating rooms of different types of surgeries. to assess antibiotic prophylaxis practices in the case of allergy to betalactam antibiotics (essentially the alternative antibiotic molecules used). The study lasted 3 months and involved 40 anesthesia-intensive care staff. Once the data had been collected from the questionnaires, they were processed using Excel, then presented in the form of tables and figures, reflecting the results obtained in relation to the aim of the study. Results: the results of antibiotic prophylaxis showed that the use of betalactam antibiotics represented 96% of practices and that the antibiotic molecule chosen as an alternative in case of betalactam allergy was compliant in 84.44% of practices in relation to SFAR 2018 recommendations. Conclusion: Antibiotic prophylaxis practices for patients allergic to betalactamines require major caution in order to limit surgical site infections and reduce hospitalization costs.

1000 Surgical antibiotic prophylaxis among patients treated for intraamniotic infection

A review of the practice of surgical antibiotic prophylaxis

Background: Surgical Antibiotic Prophylaxis (SAP) is defined as the use of antibiotics to prevent infections at a surgical site. The appropriate use of SAP is an effective and efficient modality of preventing surgical site infections. Main body: The practice of SAP is however fraught with several challenges e.g., diverse opinions among surgeons regarding the duration of surgical prophylaxis, a dearth of institutional guidelines, and poor compliance with existing guidelines. Unfortunately, the inappropriate use of SAP results in adverse clinical (e.g., increased length of hospitalization, occurrence of surgical site infections, morbidity, etc.) and economic consequences (e.g., increased healthcare costs) in surgical patients. Conclusion: This review article discusses the practice of SAP and the challenges regarding SAP. Finally, some recommendations to overcome the challenges are discussed.

What Is the Ideal Duration for Surgical Antibiotic Prophylaxis?

Background: Surgical antibiotic prophylaxis practice became common in the 1970s and has since become almost universal. The earliest articles used three doses over 12 hours with the first being administered before the start of the operation. Conclusions: The duration of prophylaxis has varied widely in practice over time, but an increasing body of evidence has supported shorter durations, most recently with recommendations in influential guidelines to avoid administration after the incision is closed.

Optimizing prophylactic antibiotic use among surgery patients in Ethiopian hospitals

BackgroundSince 2018, the Ethiopian Ministry of Health (MOH) has been working to institutionalize antimicrobial stewardship (AMS) programs across the country. The US Agency for International Development Medicines, Technologies, and Pharmaceutical Services Program supported Ethiopia’s multipronged One Health approach to combat AMR. The objective of this paper was to evaluate the effect of a quality improvement intervention to optimize the use of antimicrobials for surgical prophylaxis. MethodsBasic AMS interventions were introduced in five hospitals from January to May 2023. The AMS committees and multidisciplinary teams working at the surgical wards were trained and provided on-site support to implement surgical antibiotic prophylaxis (SAP) interventions. A before-after comparison was made for 206 medical records at baseline and 213 during the intervention phase. Qualitative data were gathered through discussions during experience-sharing workshops to supplement the quantitative results. ResultThere were improvements in the presurgery dose of the prophylactic antibiotic and its timing: the doses within the recommended range increased from 11.2 % to 61.0 % (p < 0.001) and the optimal timing increased from 68 % to 82.6 % (p < 0.001). The hospitals also demonstrated some nonsignificant improvement in the duration of prophylactic antibiotic use (from 35 % to 44.6 % [p = 0.106]), with change in practice hampered by practitioners' resistance to early discontinuation for fear of infection due to perceived weaknesses in infection prevention and control practices. Nonavailability of the recommended antibiotic of choice for surgical prophylaxis was another major challenge in addressing all the elements of SAP. The intervention demonstrated a significant antibiotic-related average cost saving, 51.8 Ethiopian birr (∼1 US dollar) per patient (p = 0.028). ConclusionShort-term investments with basic AMS interventions can help to improve SAP use in surgical wards. However, comprehensive success requires complementing AMS interventions with concurrent attention to proper supply chain and infection prevention and control.

Impact of the Five-Year Intervention of an Antimicrobial Stewardship Program on the Optimal Selection of Surgical Prophylaxis in a Hospital without Antibiotic Prescription Restrictions in Costa Rica: A Retrospective Study.

This study aims to characterize the impact of the implementation of an antimicrobial stewardship program (AMS) on the optimal selection of surgical antibiotic prophylaxis in adult patients. This is a retrospective quasi-experimental study that compared the selection and duration of antibiotics for all surgical prophylaxis prescriptions over six months, both before (pre-AMS) and after a five-year intervention of AMS (post-AMS). In addition, data related to the consumption of antibiotics, adverse drug reactions, and surgical site infections throughout the years of the intervention were analyzed. The rate of appropriate selection of antibiotic prophylaxis in surgical procedures improved to 80% during the post-AMS period. The percentage of optimal duration increased from 69.1% (N = 1598) in the pre-AMS period to 78.0% (N = 841) in the post-AMS period (p < 0.001). The consumption of ceftriaxone significantly decreased, while the use of cefazolin increased more than nine times. No severe adverse reactions or increases in surgical site infections were detected after the intervention. The implementation of an AMS in the surgical ward demonstrated a trend towards a positive overall impact on the selection and duration of prophylactic antibiotics for surgery, with positive results also observed in other variables associated with the prescription of these antibiotics.

Enhancing Surgical Outcomes: A Critical Review of Antibiotic Prophylaxis in Orthopedic Surgery.

The postoperative burden remains significant due to the possibility of prolonged hospitalization, escalated healthcare costs, and patient distress caused by postorthopedic surgicalsite infections (SSIs). Orthopedic surgery is likewise faced with a significant challenge posed by these conditions. A positive association has been observed between the presence of postorthopedic SSIs and heightened susceptibility to adverse health outcomes, along with elevated rates of morbidity and mortality. Systemic antibiotic prophylaxis (SAP) reduces the risk of acquiring an SSI. Closed fractures, open fractures, arthroplasty, and percutaneous fixation each possess distinct attributes that impact the data and antimicrobial therapy. When implementing SAP, it is crucial to strike a delicate equilibrium between maintaining effective antibiotic stewardship protocols and preventing the occurrence of SSIs. This practice effectively prevents both the incidence of negative consequences and the emergence of antibiotic resistance. The objective of this study was to examine the existing literature on the use of surgical antibiotic prophylaxis in orthopedic surgery and explore the potential consequences associated with the inappropriate administration of antibiotics.

Appropriateness of acute-care antibiotic prescriptions for community-acquired infections and surgical antibiotic prophylaxis in England: analysis of 2016 national point prevalence survey data

Estimates of inappropriate prescribing can highlight key target areas for antimicrobial stewardship (AMS) and inform national targets. To (1) define and (2) produce estimates of inappropriate antibiotic prescribing levels within acute hospital trusts in England. The 2016 national Healthcare-Associated Infections (HAI), Antimicrobial Use (AMU) and AMS point prevalence survey (PPS) was used to derive estimates of inappropriate prescribing, focusing on the four most reported community-acquired antibiotic indications (CAIs) in the PPS and surgical prophylaxis. Definitions of appropriate antibiotic therapy for each indication were developed through the compilation of national treatment guidelines. A Likert-scale system of appropriateness coding was validated and refined through a two-stage expert review process. Antimicrobial usage prevalence data were collected for 25,741 individual antibiotic prescriptions, representing 17,884 patients and 213 hospitals in England. 30.4% of prescriptions for the four CAIs of interest were estimated to be inappropriate (2054 prescriptions). The highest percentage of inappropriate prescribing occurred in uncomplicated cystitis prescriptions (62.5%), followed by bronchitis (48%). For surgical prophylaxis, 30.8% of prescriptions were inappropriate in terms of dose number, and 21.3% in terms of excess prophylaxis duration. The 2016 prevalence of inappropriate antibiotic prescribing in hospitals in England was approximated to be 30.4%; this establishes a baseline prevalence and provided indication of where AMS interventions should be prioritized. Our definitions appraised antibiotic choice, treatment duration and dose number (surgical prophylaxis only); however, they did not consider other aspects of appropriateness, such as combination therapy - this is an important area for future work.

A Self-Sustaining Antibiotic Prophylaxis Program to Reduce Surgical Site Infections.

Background: Our multi-institutional healthcare system had a higher-than-expected surgical site infection (SSI) rate. We aimed to improve our peri-operative antibiotic administration process. Gap analysis identified three opportunities for process improvement: standardized antibiotic selection, standardized second-line antibiotic agents for patients with allergies, and feedback regarding antibiotic administration compliance. Hypothesis: Implementation of a multifaceted quality improvement initiative including a near-real-time pre-operative antibiotic compliance feedback tool will improve compliance with antibiotic administration protocols, subsequently lowering SSI rate. Methods: A compliance feedback tool designed to provide monthly reports to all anesthesia and surgical personnel was implemented at two facilities, in September 2017 and December 2018. Internal case data were tracked for antibiotic compliance through June 2021, and these data were merged with American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) data at the case level to provide process and outcome measures for SSIs. Implementation success was evaluated by comparing protocol compliance and risk-adjusted rates of superficial and deep SSI before and after the quality improvement implementation. Results: A total of 20,385 patients were included in this study; 11,548 patients in the pre-implementation and 8,837 in the post-implementation groups. Baseline patient and operative characteristics were similar between groups, except the post-implementation group had a higher median expected SSI rate (2.2% vs. 1.6%). Post-implementation, antibiotic protocol compliance increased from 86.3% to 97.6%, and superficial and deep SSIs decreased from 2.8% to 1.9% (p < 0.001). The odds of superficial and deep SSI in patients in the post-implementation group was 0.69 (0.57, 0.83) times the odds of superficial and deep SSI in pre-implementation patients while adjusting for age, gender, diabetes mellitus, American Society of Anesthesiologists Physical Status (ASA) classification, wound class, smoking, and chronic obstructive pulmonary disease (COPD). Observed-to-expected ratios of superficial and deep SSI decreased from 0.82 to 0.48 after the intervention. Conclusions: Surgical antibiotic prophylaxis standardization and providing near-real-time individualized feedback resulted in sustained improvement in peri-operative antibiotic compliance rates and reduced superficial and deep SSIs.
