Declaration on infection prevention and management in global surgery.

Surgeons in their daily practice are at the forefront in preventing and managing infections. However, among surgeons, appropriate measures of infection prevention and management are often disregarded. The lack of awareness of infection and prevention measures has marginalized surgeons from this battle. Together, the Global Alliance for Infections in Surgery (GAIS), the World Society of Emergency Surgery (WSES), the Surgical Infection Society (SIS), the Surgical Infection Society-Europe (SIS-E), the World Surgical Infection Society (WSIS), the American Association for the Surgery of Trauma (AAST), and the Panamerican Trauma Society (PTS) have jointly completed an international declaration, highlighting the threat posed by antimicrobial resistance globally and the need for preventing and managing infections appropriately across the surgical pathway. The authors representing these surgical societies call all surgeons around the world to participate in this global cause by pledging support for this declaration for maintaining the effectiveness of current and future antibiotics.

Are trauma surgeons prepared? A survey of trauma surgeons' disaster preparedness before and during the COVID-19 pandemic.

Objective: US trauma centers (TCs) must remain prepared for mass casualty incidents (MCIs). However, trauma surgeons may lack formal MCI training. The recent COVID-19 pandemic drove multiple patient surges, overloaded Emergency Medical Services (EMS) agencies, and stressed TCs. This survey assessed trauma surgeons' MCI training, experience, and system and personal preparedness before the pandemic compared with the pandemic's third year. Methods: Survey invitations were emailed to all 1544 members of the American Association for the Surgery of Trauma in 2019, and then resent in 2022 to 1575 members with additional questions regarding the pandemic. Questions assessed practice type, TC characteristics, training, experience, beliefs about personal and hospital preparedness, likelihood of MCI scenarios, interventions desired from membership organizations, and pandemic experiences. Results: The response rate was 16.7% in 2019 and 12% in 2022. In 2022, surgeons felt better prepared than their hospitals for pandemic care, mass shootings, and active shooters, but remained feeling less well prepared for cyberattack and hazardous material events, compared with 2019. Only 35% of the respondents had unintentional MCI response experience in 2019 or 2022, and even fewer had experience with intentional MCI. 78% had completed a Stop the Bleed (STB) course and 63% own an STB kit. 57% had engaged in family preparedness activities; less than 40% had a family action plan if they could not come home during an MCI. 100% of the respondents witnessed pandemic-related adverse events, including colleague and coworker illness, patient surges, and resource limitations, and 17% faced colleague or coworker death. Conclusions: Trauma surgeons thought that they became better at pandemic care and rated themselves as better prepared than their hospitals for MCI care, which is an opportunity for them to take greater leadership roles. Opportunities remain to improve surgeons' family and personal MCI preparedness. Surgeons' most desired professional organization interventions include advocacy, national standards for TC preparedness, and online training. Level of evidence: VII, survey of expert opinion.

Developing a National Trauma Research Action Plan: Results from the prehospital and mass casualty research Delphi survey.

BACKGROUND: The National Academies of Sciences, Engineering, and Medicine 2016 trauma system report recommended a National Trauma Research Action Plan to strengthen and guide future trauma research. To address this recommendation, 11 expert panels completed a Delphi survey process to create a comprehensive research agenda, spanning the continuum of trauma care. We describe the gap analysis and high-priority research questions generated from the National Trauma Research Action Plan panel on prehospital and mass casualty trauma care. METHODS: We recruited interdisciplinary national experts to identify gaps in the prehospital and mass casualty trauma evidence base and generate prioritized research questions using a consensus-driven Delphi survey approach. We included military and civilian representatives. Panelists were encouraged to use the Patient/Population, Intervention, Compare/Control, and Outcome format to generate research questions. We conducted four Delphi rounds in which participants generated key research questions and then prioritized the questions on a 9-point Likert scale to low-, medium-, and high-priority items. We defined consensus as ≥60% agreement on the priority category and coded research questions using a taxonomy of 118 research concepts in 9 categories. RESULTS: Thirty-one interdisciplinary subject matter experts generated 490 research questions, of which 433 (88%) reached consensus on priority. The rankings of the 433 questions were as follows: 81 (19%) high priority, 339 (78%) medium priority, and 13 (3%) low priority. Among the 81 high-priority questions, there were 46 taxonomy concepts, including health systems of care (36 questions), interventional clinical trials and comparative effectiveness (32 questions), mortality as an outcome (30 questions), prehospital time/transport mode/level of responder (24 questions), system benchmarks (17 questions), and fluid/blood product resuscitation (17 questions). CONCLUSION: This Delphi gap analysis of prehospital and mass casualty care identified 81 high-priority research questions to guide investigators and funding agencies for future trauma research.

Surgical Infection Society Guidance for Operative and Peri-Operative Care of Adult Patients Infected by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2).

Background: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)-associated viral infection (coronavirus disease 2019, COVID-19) is a virulent, contagious viral pandemic that is affecting populations worldwide. As with any airborne viral respiratory infection, surgical and non-surgical patients may be affected. Methods: Review and synthesis of pertinent English-language literature pertaining to COVID-19 infection among adult patients. Results: COVID-19 disease that requires hospitalization results in critical illness approximately 25% of the time and requires mechanical ventilation with positive airway pressure. Acute kidney injury, a marked hypercoagulable state, and sometimes myocarditis can be features of COVID-19 in addition to the characteristic severe acute lung injury. Even if not among the most seriously afflicted, older patients with medical comorbidities are both predisposed to infection and risk increased morbidity and mortality, however, all persons presenting for surgical intervention should be suspected of infection (and thus transmissibility) even if asymptomatic. Although most elective surgery has been curtailed by administrative or governmental fiat, patients will still need urgent or emergency operative intervention for time-sensitive disease processes such as malignant neoplasia or for true emergencies such as perforated viscus or traumatic injury. It is possible to provide safe surgical care for SARS-CoV-2-positive patients and minimize nosocomial transmission to healthcare workers. Conclusions: This guidance will facilitate appropriate protection of patients and staff, and maintenance of infection control measures to assist surgical personnel and facilities to prepare for COVID-19-infected adult patients requiring urgent or emergent operative intervention and to provide optimal patient care.

Key Ways to Prevent Infection When There Is No "Building": Aspects for the Field.

BACKGROUND: Infection control is a critical aspect in the continuum of surgical care. Much of what is outlined in the literature pertains to hospital-based practice, with only recent attention paid to the more austere environments, particularly those faced during humanitarian or combat operations. OBJECTIVE: This manuscript provides a brief historical review of the development of infection control practices and further identifies and outlines several aspects necessary to successful program applications in austere environments. RESULTS: Hand hygiene remains the simplest form of infection control. Use of alcohol-based hand sanitizer is a logistically reasonable option for most circumstances, mitigating the requirement for clean running water to facilitate more traditional "soap and water" methods of hand disinfection. Environmental decontamination, patient cohorting, and patient isolation based on existing colonization/infection also has demonstrated efficacy in controlling cross-contamination and is feasible in most austere environments. Finally, senior leadership engagement with deliberate planning, antimicrobial stewardship, and vigorous quality and process improvement algorithms have resulted in reduced rates of critical infections in these settings. CONCLUSIONS: Basic tenets of infection control can be achieved even in resource-poor environments. Meticulous attention to adhering to these principles, with support from senior medical and operational leadership, facilitates improvements in infection control outcomes. There remains, however, a need for additional robust outcomes data regarding best practices in these environments.

Short-Course Antimicrobial Therapy Does Not Increase Treatment Failure Rate in Patients with Intra-Abdominal Infection Involving Fungal Organisms.

BACKGROUND: Fungi frequently are isolated in intra-abdominal infections (IAI). The Study to Optimize Peritoneal Infection Therapy (STOP-IT) recently suggested short-course treatment for patients with IAI. It remains unclear whether the presence of fungi in IAI affects the optimal duration of Antimicrobial therapy. We hypothesized that a shorter treatment course in IAI with fungal organisms would be associated with a higher rate of treatment failure. METHODS: Patients enrolled in the STOP-IT trial were stratified according to the presence or absence of a fungal isolate. They were analyzed as a subgroup based on original randomization to either the control group or an experimental group that received a four-day course of Antimicrobial therapy and by comparison with those without a fungal component to their infection. Descriptive comparisons were performed using a χ2, Fisher exact, or Kruskal-Wallis test as appropriate. The primary outcome was a composite of recurrent IAI, surgical site infection, and death. RESULTS: A total of 411 patients in the study (79%) had available culture data, of which 58 (14%) had positive fungal cultures. The most common organisms were Candida albicans and C. glabrata. The treatment failure rate was equivalent in the experimental and control arms (29.6% vs. 22.6%; p = 0.54). Patients with fungal isolates were more likely to have malignant disease (25.9% vs. 9.6%; p = 0.0004) and coronary artery disease (22% vs. 12%; p = 0.04), but were otherwise similar to those without fungal isolates. Patients with fungal isolates had more hospital days (median 10 vs. 7; p < 0.0001) and more days to resumption of enteral intake (median 5 vs. 3; p = 0.0006), but there was no difference in the composite outcome. CONCLUSIONS: Patients with IAI involving fungal organisms randomized to a shorter course of Antimicrobial therapy had no difference in the rate of treatment failure. These results suggest that the presence of fungi in IAI may not indicate independently the need for a longer course of Antimicrobial therapy.

Ethical considerations in embedding a surgeon in a military or civilian tactical team.

Tactical emergency medical services (TEMS) bring immediate medical support to the inner perimeter of special weapons and tactics team activations. While initially envisioned as a role for an individual dually trained as a police officer and paramedic, TEMS is increasingly undertaken by physicians and paramedics who are not police officers. This report explores the ethical underpinnings of embedding a surgeon within a military or civilian tactical team with regard to identity, ethically acceptable actions, triage, responsibility set, training, certification, and potential future refinements of the role of the tactical police surgeon.

The St. Jude Medical cardiac valve prosthesis: long-term follow up of patients having double valve replacement.

BACKGROUND AND AIM OF THE STUDY: Between October 1977 and February 2002, a total of 343 patients (mean age 62 +/- 13 years; range: 19-91 years) underwent double valve replacement (DVR) with the St. Jude Medical (SJM) heart valve. Among the replacements, 337 (98%) were aortic and mitral in nature. Concomitant coronary artery bypass was performed in 73 patients (21%). METHODS: Cardiac Surgical Associates has maintained an independent database of patients undergoing valve replacement with the SJM prosthesis since the valve's first implantation in October 1977. Patients were contacted by questionnaire and/or telephone (94% complete) between November 2002 and June 2003. The patients' hospital course and valve-related events were verified by patient chart review and/or physician contact. RESULTS: Operative mortality was 8% (n = 29); mortality was valve-related in two cases. The mean follow up was 6.5 +/- 6.0 years (range: 1 month to 24 years); total follow up was 2,226 patient-years. Over 25 years, patient freedom from late mortality was 62%, and from valve-related mortality 78%. Freedom from thromboembolic events was 82% (93% from permanent defect), from bleeding events 76%, from endocarditis 98%, from valve thrombosis 99.9%, and from reoperation 98%. Six reoperations were carried out in five patients (2%), valve repair or replacement in five (2%), and suture closure of paravalvular leak in one patient (0.3%). There were no valve structural failures reported. CONCLUSION: The SJM valve has proven to be an effective and durable heart valve prosthesis. Over the long-term, the event rate is low and there is excellent freedom from reoperation in the double valve configuration.

Five-year follow up of the ATS mechanical heart valve.

BACKGROUND AND AIM OF THE STUDY: Between January 1, 1997 and December 31, 2001, a total of 342 patients underwent aortic valve replacement (AVR) or mitral valve replacement (MVR) with the ATS Medical prosthesis. The initial three-year phase of this study took place under a United States Food and Drug Administration-approved investigational device exemption study. The study aim was to determine the incidence of valve-related events in up to five years of follow up after valve implantation, and to assess patient disturbance from valve noise. METHODS: Patients were consecutively enrolled to undergo AVR or MVR with the ATS prosthesis. Follow up studies were conducted by patient questionnaire and/or telephone call. Follow up was 96% complete. AVR was conducted in 246 patients (80 with coronary bypass), and MVR in 96 patients (29 with coronary bypass). RESULTS: The overall operative mortality was 2.6% (n = 9; AVR 3.2%, n = 8; MVR 1.0%, n = 1), with two deaths being valve-related (0.6%). In 878 patient-years (pt-yr) of follow up (613 pt-yr for AVR; 265 pt-yr for MVR) there were an additional 22 deaths. Five deaths (0.6%/pt-yr) were valve-related: two were neuroembolic (both MVR), one from endocarditis (AVR), and two from bleeding events (both AVR). Late valve-related complications (>30 days) included 17 episodes of major bleeding (11 AVR, 1.8%/pt-yr; six MVR, 2.3%/pt-yr), five permanent neuroembolic events (four AVR, 0.7%/pt-yr; one MVR, 0.4%/pt-yr); 16 transient neuroembolic events (10 AVR, 1.6%/pt-yr; six MVR, 2.3%/pt-yr); three transient peripheral emboli (two AVR, 0.3%/pt-yr; one MVR, 0.4%/pt-yr); four paravalvular leaks (two AVR, 0.3%/pt-yr; two MVR, 0.8%/pt-yr); and one episode of valve thrombosis (MVR, 0.4%/pt-yr; AVR, 0%/pt-yr). Reoperation was required in two patients: one AVR (paravalvular leak, 0.2%/pt-yr) and one MVR (replacement due to thrombosis, 0.4%/pt-yr). CONCLUSION: These results indicate that intermediate-term results with the ATS mechanical prosthesis continue to be excellent, though further long-term follow up is warranted.

Opposite trends in coronary artery and valve surgery in a large multisurgeon practice, 1979-1999.

BACKGROUND: Trends in coronary artery bypass (CAB) and valve operations (VO) may help predict the future of cardiac surgery in the context of changing case mix, shifting paradigms, emerging technology, and population demographics. METHODS: We retrospectively reviewed all 30,319 adult CAB and VO in our group from 1979 to 1999 according to specific procedures. RESULTS: Coronary artery bypass volumes peaked in 1996 at 1,895 cases, declining 15.3% to 1,605 cases in 1999 with a decrease in risk profile and percent reoperations and an increase in mean age and percent octogenarians, prior percutaneous coronary interventions (PCI), left internal mammary artery (LIMA) graft usage, off-pump technology usage, and hospital mortality of reoperations. Right internal mammary grafts were employed infrequently and radial artery grafts transiently. Overall VO volumes continued to increase 24.0% since 1996, from 470 to 583 cases with a decreased risk profile, increased mean age, and percent octogenarians and prior PCI. The percentage of mechanical valve implants decreased, while the percentage of various tissue solutions for valve disease increased. Limited access incisions and port-access were employed transiently with CAB and VO. CONCLUSIONS: Coronary artery bypass volumes are decreasing, with an increasing percentage of LIMA grafts and off-pump cases. Valve operation volumes are steadily increasing, with a decreasing percentage of mechanical valve implants, in favor of various tissue solutions.
