Knowledge, awareness, and attitude towards infection prevention and management among surgeons: identifying the surgeon champion

Phage therapy as a glimmer of hope in the fight against the recurrence or emergence of surgical site bacterial infections

PURPOSE

Over the last decade, surgery rates have risen alarmingly, and surgical-site infections are expanding these concerns. In spite of advances in infection control practices, surgical infections continue to be a significant cause of death, prolonged hospitalization, and morbidity. As well as the presence of bacterial infections and their antibiotic resistance, biofilm formation is one of the challenges in the treatment of surgical wounds.

METHODS

This review article was based on published studies on inpatients and laboratory animals receiving phage therapy for surgical wounds, phage therapy for tissue and bone infections treated with surgery to prevent recurrence, antibiotic-resistant wound infections treated with phage therapy, and biofilm-involved surgical wounds treated with phage therapy which were searched without date restrictions.

RESULTS

It has been shown in this review article that phage therapy can be used to treat surgical-site infections in patients and animals, eliminate biofilms at the surgical site, prevent infection recurrence in wounds that have been operated on, and eradicate antibiotic-resistant infections in surgical wounds, including multi-drug resistance (MDR), extensively drug resistance (XDR), and pan-drug resistance (PDR). A cocktail of phages and antibiotics can also reduce surgical-site infections more effectively than phages alone.

CONCLUSION

In light of these encouraging results, clinical trials and research with phages will continue in the near future to treat surgical-site infections, biofilm removal, and antibiotic-resistant wounds, all of which could be used to prescribe phages as an alternative to antibiotics.

Association Between the Lockdown for SARS-CoV-2 (COVID-19) and Reduced Surgical Site Infections after Vascular Exposure in the Groin at Two Italian Academic Hospitals

BACKGROUND

The aim of this study was to evaluate whether the scrupulous hygiene rules and the restriction of contacts during the lockdown owing to the COVID-19 pandemic affected the rate and severity of surgical site infections (SSI) after vascular exposure in the groin at two Italian University Hospitals.

METHODS

Starting from March 2020, strict hygiene measures for protection of health care workers (HCW) and patients from COVID-19 infection were implemented, and partly lifted in July 2020. The main exposure for analysis purposes was the period in which patients were operated. Accordingly, study subjects were divided into two groups for subsequent comparisons (preCOVID-19 era: March-June 2018-2019 versus COVID-19 era: March-June 2020). The primary endpoint was the occurrence of superficial and/or deep SSI within 30 days after surgery. The Centers for Disease Control and Prevention definitions were used to classify superficial and deep SSI.

RESULTS

A total of 194 consecutive patients who underwent vascular exposure in the groin were retrospectively analyzed. Of those, 60 underwent surgery from April 1, 2018 to June 30 of the same year; 83 from April 1, 2019 to June 30 of the same year; and 51 from April 1, 2020 to June 30 of the same year. The mean age of the study cohort was 75 years and 140 (72%) were males. Patients who were operated in the COVID-19 era were less likely to develop SSI (10% vs. 28%; P = 0.008), including both deep SSI (4% vs. 13%; P = 0.04) and superficial SSI (6% vs. 15%; P = 0.05). After multivariate adjustments, being operated in the COVID-19 era was found to be a negative predictor for development of an SSI (odds ratio [OR] = 0.31; 95% confidence interval [CI] = 0.09-0.76; P < 0.001) or deep SSI (OR = 0.21; 95% CI = 0.03-0.98; P < 0.001). Operative time was also found as independent predictor for the development of deep SSI (OR = 1.21; 95%CI = 1.21-1.52; P = 0.02). Using binary logistic regression, there were no independent predictors of superficial SSI that could be identified.

CONCLUSIONS

Vascular exposure in the groin carries a non-negligible risk of SSI. In this study, we provided important insights that are simple and easily viable precautions (such as the universal use of surgical masks both for patients and health care professionals during wound care, the widespread diffusion of hand sanitizers, and the reduction of the number of visitors in the surgical wards) could be promising and safe tools for SSI risk reduction.

ACOI Surgical Site Infections Management Academy (ACOISSIMA)

Background:

Surgical site infections (SSIs) are the most common cause of healthcare-associated infections in surgical patients. Many SSIs may be preventable if simple measures are respected. Despite evidence supporting the effectiveness of evidence-based practices in Infection Prevention and Control, many surgeons fail to implement them.

Methods:

To clarify the key issues in the prevention of SSIs, an expert panel designated by the board of directors of Associazione Chirurghi Ospedalieri Italiani—Italian Surgical Association (ACOI) convened in Rome, Italy, on 16 December 2021, for a consensus conference.

Results:

The expert panel approved 11 evidence-based statements regarding the prevention of SSIs. A article was drafted and reviewed by the expert panel, finally obtaining this document that represents the executive summary of the consensus.

Conclusions:

The document aims to disseminate best practices among Italian surgeons and summarizes the ACOI recommendations for the prevention of SSIs.

The "Torment" of Surgical Antibiotic Prophylaxis among Surgeons

Surgical antibiotic prophylaxis (SAP) is one of the peri-operative measures for preventing surgical site infections (SSIs). Its goal is to counteract the proliferation of bacteria in the surgical site during intervention in order to reduce the risk of SSIs. SAP should be administered for surgical interventions where the benefit expected (prevention of SSIs) is higher compared to the risk (serious side effects, such as acute kidney injury, Clostridioides difficile infection, and the spread of antimicrobial resistance). In prescribing SAP, surgeons should have both the awareness necessary “to handle antibiotics with care”, and the knowledge required to use them appropriately.

Prospective multicenter study on the incidence of surgical site infection after emergency abdominal surgery in China

There is still a lack of relevant studies on surgical site infection (SSI) after emergency abdominal surgery (EAS) in China. This study aims to understand the incidence of SSI after EAS in China and discuss its risk factors. All adult patients who underwent EAS in 47 hospitals in China from May 1 to 31, 2018, and from May 1 to June 7, 2019, were enrolled in this study. The basic information, perioperative data, and microbial culture results of infected incision were prospectively collected. The primary outcome measure was the incidence of SSI after EAS, and the secondary outcome variables were postoperative length of stay, ICU admission rate, ICU length of stay, 30-day postoperative mortality, and hospitalization cost. Univariate and multivariate logistic regression were used to analyze the risk factors. The results were expressed as the odds ratio and 95% confidence interval. A total of 953 patients [age 48.8 (SD: 17.9), male 51.9%] with EAS were included in this study: 71 patients (7.5%) developed SSI after surgery. The main pathogen of SSI was Escherichia coli (culture positive rate 29.6%). Patients with SSI had significantly longer overall hospital (p < 0.001) and ICU stays (p < 0.001), significantly higher ICU admissions (p < 0.001), and medical costs (p < 0.001) than patients without SSI. Multivariate logistic regression analysis showed that male (P = 0.010), high blood glucose level (P < 0.001), colorectal surgery (P < 0.001), intestinal obstruction (P = 0.045) and surgical duration (P = 0.007) were risk factors for SSI, whereas laparoscopic surgery (P < 0.001) was a protective factor. This study found a high incidence of SSI after EAS in China. The occurrence of SSI prolongs the patient's hospital stay and increases the medical burden. The study also revealed predictors of SSI after EAS and provides a basis for the development of norms for the prevention of surgical site infection after emergency abdominal surgery.

Expert commentary on the challenges and opportunities for surgical site infection prevention through implementation of evidence-based guidelines in the Asia-Pacific Region

INTRODUCTION

Surgical site infections (SSIs) are a significant source of morbidity and mortality in the Asia-Pacific region (APAC), adversely impacting patient quality of life, fiscal productivity and placing a major economic burden on the country's healthcare system. This commentary reports the findings of a two-day meeting that was held in Singapore on July 30-31, 2019, where a series of consensus recommendations were developed by an expert panel composed of infection control, surgical and quality experts from APAC nations in an effort to develop an evidence-based pathway to improving surgical patient outcomes in APAC.

METHODS

The expert panel conducted a literature review targeting four sentinel areas within the APAC region: national and societal guidelines, implementation strategies, postoperative surveillance and clinical outcomes. The panel formulated a series of key questions regarding APAC-specific challenges and opportunities for SSI prevention.

RESULTS

The expert panel identified several challenges for mitigating SSIs in APAC; (a) constraints on human resources, (b) lack of adequate policies and procedures, (c) lack of a strong safety culture, (d) limitation in funding resources, (e) environmental and geographic challenges, (f) cultural diversity, (g) poor patient awareness and (h) limitation in self-responsibility. Corrective strategies for guideline implementation in APAC were proposed that included: (a) institutional ownership of infection prevention strategies, (b) perform baseline assessments, (c) review evidence-based practices within the local context, (d) develop a plan for guideline implementation, (e) assess outcome and stakeholder feedback, and (f) ensure long-term sustainability.

CONCLUSIONS

Reducing the risk of SSIs in APAC region will require: (a) ongoing consultation and collaboration among stakeholders with a high level of clinical staff engagement and (b) a strong institutional and national commitment to alleviate the burden of SSIs by embracing a safety culture and accountability.

Impact of lockdown for SARS-CoV-2 (COVID-19) on surgical site infection rates: a monocentric observational cohort study

Surgical site infections are the most common in-hospital acquired infections. The aim of this study and the primary endpoint is to evaluate how the measures to reduce the SARS-CoV-2 spreading affected the superficial and deep SSI rate. A total of 541 patients were included. Of those, 198 from March to April 2018, 220 from March till April 2019 and 123 in the COVID-19 era from March to April 2020. The primary endpoint occurred in 39 over 541 patients. In COVID-19 era, we reported a lower rate of global SSIs (3.3% vs. 8.4%; p 0.035), few patients developed a superficial SSIs (0.8% vs. 3.4%; p 0.018) and none experienced deep SSIs (0% vs. 3.4%; p 0.025). Comparing the previous two “COVID-19-free” years, no significative differences were reported. At multivariate analysis, the measures to reduce the SARS-CoV-2 spread (OR 0.368; p 0.05) were independently associated with the reduction for total, superficial and deep SSIs. Moreover, the presence of drains (OR 4.99; p 0.009) and a Type III–IV of SWC (OR 1.8; p 0.001) demonstrated a worse effect regarding the primary endpoint. Furthermore, the presence of the drain was not associated with an increased risk of superficial and deep SSIs. In this study, we provided important insights into the superficial and deep SSIs risk assessment for patients who underwent surgery. Simple and easily viable precautions such as wearing surgical masks and the restriction of visitors emerged as promising tools for the reduction of SSIs risk.

Antimicrobial resistance (AMR) is a phenomenon resulting from the natural evolution of microbes. Nonetheless, human activities accelerate the pace at which microorganisms develop and spread resistance. AMR is a complex and multidimensional problem, threatening not only human and animal health, but also regional, national, and global security, and the economy. Inappropriate use of antibiotics, and poor infection prevention and control strategies are contributing to the emergence and dissemination of AMR. All healthcare providers play an important role in preventing the occurrence and spread of AMR. The organization of healthcare systems, availability of diagnostic testing and appropriate antibiotics, infection prevention and control practices, along with prescribing practices (such as over-the-counter availability of antibiotics) differs markedly between high-income countries and low and middle-income countries (LMICs). These differences may affect the implementation of antibiotic prescribing practices in these settings. The strategy to reduce the global burden of AMR includes, among other aspects, an in-depth modification of the use of existing and future antibiotics in all aspects of medical practice. The Global Alliance for Infections in Surgery has instituted an interdisciplinary working group including healthcare professionals from different countries with different backgrounds to assess the need for implementing education and increasing awareness about correct antibiotic prescribing practices across the surgical pathways. This article discusses aspects specific to LMICs, where pre-existing factors make surgeons' compliance with best practices even more important.

Intra-Abdominal Infections by Carbapenemase-Producing Enterobacteriaceae in a Surgical Unit: Counting Mortality, Stay, and Costs

Background: Carbapenemase-producing Enterobacteriaceae (CPE)-related infections are a problem in public health at present, including intra-abdominal infections (IAI) and surgical populations. The aim of this study was to determine mortality and related risk factors, length of stay (LOS,) and costs for CPE-IAI in surgical patients. Patients and Methods: Review of CPE-related IAI acquired during admission in a general surgery department from January 2013 to December 2018. A mortality analysis was performed specifically in patients with CPE-IAI, and a global analysis of IAI including patients with CPE-IAI (cases) and matched patients with IAI by non-resistant bacteria (controls). Results: Forty patients with CPE-IAI were included, OXA-48-producing Klebsiella pneumoniae was present in 85%. Global mortality rate at 30 days for CPE-IAI was 17.5%; mortality-related factors were: solid tumor (p = 0.009), metastatic disease (p = 0.005), immunodeficiency (p = 0.039), blood transfusion (p = 0.009), and septic shock (p = 0.011). Predictors related to mortality for IAI in the global analysis included age (p = 0.046), Charlson index (p = 0.036), CPE isolation (p = 0.003), and septic shock (p < 0.001). Median global LOS was 43 days (IQR 27-64) in patients with CPE-IAI, and 27 days (IQR 18-35) in controls (p < 0.001). Median global cost of admission was $31,671 (IQR 14,006-55,745) for patients with CPE-IAI and $20,306 (IQR 11,974-27,947) for controls (p = 0.064). The most relevant locations of underlying disease for CPE-IAI were: colorectal (32.5%) with 57-day LOS (IQR 34-65) and cost of $42,877 (IQR 18,780-92,607), and pancreas (25%) with 60-day LOS (IQR 32-99) and cost of $56,371 (IQR 32,590-113,979). Conclusion: Carbapenemase-producing Enterobacteriaceae-related IAI is associated with substantial mortality, LOS, and costs. Factors related to CPE-IAI mortality are solid tumor, metastatic disease, immunodeficiency, blood transfusion, and septic shock. Carbapenemase-producing Enterobacteriaceae isolation in IAI implies higher risk of mortality.

From uptake to access: a decade of learning from the ACOG LARC program

The Long-Acting Reversible Contraception (LARC) Program at the American College of Obstetricians and Gynecologists (ACOG) celebrated its 10^th anniversary in 2018. This Viewpoint article reviews opportunities, challenges, and lessons learned by the ACOG LARC Program throughout the last decade. Housed within the largest medical organization representing women's health providers, the LARC Program supports change by developing resources for clinicians, healthcare systems, healthcare organizations, and policy makers. The Program's Postpartum Contraceptive Access Initiative (PCAI) meets specific needs identified by an Expert Work Group using implementation science principles, including improved contraceptive counseling and clinician training, and institution-wide sustainable systems change in billing, coding, pharmacy, and electronic medical record integration. Key lessons learned include the importance of centering patient preferences and autonomy, developing foundational evidence-based guidance, supporting practice change through implementation tools and collaboration with local champions, advocating for insurance and payment policy, and partnering with other health care organizations to develop robust resources to improve patient access to the full range of contraceptive methods.

Influence of national culture and context on healthcare workers' perceptions of infection prevention in Greek neonatal intensive care units

BACKGROUND

Healthcare-associated infections (HAIs) in neonatal intensive care units (NICUs) result in increased morbidity, mortality and healthcare costs. HAI rates in Greek NICUs are among the highest in Europe. There is a need to identify the factors that influence the transmission of HAIs and implementation of prevention interventions in this setting.

AIM

To understand healthcare workers' perceptions about HAI prevention in Greek NICUs.

METHODS

Qualitative interviews were conducted with NICU staff (physicians and nurses) and infection prevention stakeholders (infectious diseases physicians and infection control nurses) working in three hospitals in Athens. Interviews were conducted in Greek, transcribed and translated into English, and analysed using a modified grounded theory approach.

FINDINGS

Interviews were conducted with 37 respondents (20 physicians and 17 nurses). Four main barriers to HAI prevention were identified: (1) resource limitations leading to understaffing and cramped space; (2) poor knowledge about HAI prevention; (3) Greek-specific cultural norms, including hierarchy-driven decisions, a reluctance for public workers to do more than they are paid for, a belief that personal experience trumps evidence-based knowledge, and reactive rather than proactive approaches to societal challenges; and (4) lack of a national infection prevention infrastructure. Respondents believed that these barriers could be overcome through organized initiatives, high-quality HAI performance data, interpersonal interactions to build engagement around HAI prevention, and leveraging the hierarchy to promote change from the 'top down'.

CONCLUSION

Implementing HAI prevention interventions in Greek NICUs will require consideration of contextual features surrounding the delivery of care, with particular attention paid to national culture.

Awareness of Practice and Comparison with Best Evidence in Surgical Site Infection Prevention in Colorectal Surgery

Background: The use of mechanical bowel preparation and prophylaxis with oral antimicrobial agents can prevent surgical site infection (SSI) in colorectal surgical procedures, but routine adoption of these and other practices by surgeons has been limited. The aim of this study was to determine the actual practice and surgeon beliefs about preventative measures in elective colorectal operations and to compare them with established recommendations.

Methods: Web-based survey was sent to colorectal surgeons assessing knowledge, beliefs, and practices regarding the use of preventative measures for SSI.

Results: Of 355 surgeons, 33% had no feedback of SSI rate; 60% believed in evidence for normothermia, wound edge protection, and use of alcohol solution, and reported use of these strategies. There was a discrepancy in the assumed evidence and use of hyperoxia, glove replacement after anastomosis, surgical tools replacement, and saline surgical site lavage. Most of respondents believe that oral antibiotic prophylaxis diminishes infection, but is indicated only by one third of them. Few surgeons believe in MBP, but many actually use it. Most surgeons believe that there is a discrepancy between published guidelines and actual clinical practice. As proper means to implement guidelines, checklists, standardized orders, surveillance, feedback of SSI rates, and educational programs are rated most highly by surgeons, but few of these are in place at their institutions.

Conclusions: Gaps in the translation of evidence into practice remain in the prevention of SSI in colorectal surgical procedures. Several areas for improvement have been identified. Specific implementation strategies should be addressed in colorectal units.

Staff experiences of enhanced recovery after surgery: systematic review of qualitative studies

OBJECTIVES

To conduct a systematic review of qualitative studies which explore health professionals' experiences of and perspectives on the enhanced recovery after surgery (ERAS) pathway.

DESIGN

Systematic review of qualitative literature using a qualitative content analysis. Literature includes the experiences and views of a wide range of multidisciplinary team and allied health professional staff, to incorporate a diverse range of clinical and professional perspectives.

DATA SOURCES

PsycINFO, Medline, CINAHL and PubMed were searched in May 2017.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

The searches included relevant qualitative studies across a range of healthcare contexts. We included studies published from 2000 to 2017, as an appropriate time frame to capture evidence about ERAS after implementation in the late 1990s. Only studies published in the English language were included, and we included studies that explicitly stated that they used qualitative approaches.

DATA EXTRACTION AND SYNTHESIS

Literature searches were conducted by the first author and checked by the second author: both contributed to the extraction and analysis of data. Studies identified as relevant were assessed for eligibility using the Critical Appraisal Skills Programme guidance.

RESULTS

Eight studies were included in the review, including studies in six countries and in four surgical specialties. Included studies focus on health professionals' experiences of ERAS before, during and after implementation in colorectal surgery, gastrointestinal surgery, abdominal hysterectomy and orthopaedics. Five main themes emerged in the analysis: communication and collaboration, resistance to change, role and significance of protocol-based care, and knowledge and expectations. Professionals described the importance of effective multidisciplinary team collaboration and communication, providing thorough education to staff and patients, and appointing a dedicated champion as means to implement and integrate ERAS pathways successfully. Evidence-based guidelines were thought to be useful for improvements to patient care by standardising practices and reducing treatment variations, but were thought to be too open to interpretation at local levels. Setting and managing 'realistic' expectations of staff was seen as a priority. Staff attitudes towards ERAS tend to become more favourable over time, as practices become successfully 'normalised'. Strengths of the review are that it includes a wide range of different studies, a variety of clinical populations, diversity of methodological approaches and local contexts. Its limitation is the inclusion of a small number of studies, although these represent six countries and four surgical specialties, and so our findings are likely to be transferable.

CONCLUSIONS

Staff feel positive about the implementation of ERAS, but find the process is complex and challenging. Challenges can be addressed by ensuring that multidisciplinary teams understand ERAS principles and guidelines, and communicate well with one another and with patients. Provision of comprehensive, coherent and locally relevant information to health professionals is helpful. Identifying and recruiting local ERAS champions is likely to improve the implementation and delivery of ERAS pathways.
