Risk Factors Analysis of Surgical Infection Using Artificial Intelligence: A Single Center Study.

Background: Surgical site infections (SSIs) have a major role in the evolution of medical care. Despite centuries of medical progress, the management of surgical infection remains a pressing concern. Nowadays, the SSIs continue to be an important factor able to increase the hospitalization duration, cost, and risk of death, in fact, the SSIs are a leading cause of morbidity and mortality in modern health care. Methods: A study based on statistical test and logistic regression for unveiling the association between SSIs and different risk factors was carried out. Successively, a predictive analysis of SSIs on the basis of risk factors was performed. Results: The obtained data demonstrated that the level of surgery contamination impacts significantly on the infection rate. In addition, data also reveals that the length of postoperative hospital stay increases the rate of surgical infections. Finally, the postoperative length of stay, surgery department and the antibiotic prophylaxis with 2 or more antibiotics are a significant predictor for the development of infection. Conclusions: The data report that the type of surgery department and antibiotic prophylaxis there are a statistically significant predictor of SSIs. Moreover, KNN model better handle the imbalanced dataset (48 infected and 3983 healthy), observing highest accuracy value.

Does delaying surgery for “healthy” hip fracture patients have increased complications and mortality?

IntroductionSurgical delay is one of the risk factors for mortality and morbidity in patients with HF. One of the causes of delay is due to admission on Thursday-Friday, weekends, holidays or previous periods. The final objective of this study is to analyze administrative-organizational delay in complication and mortality rates. Material and methodsA total of 607 cases of surgically operated hip fractures were analyzed. Two groups were established, one of them operated on in < 48 h (ND group) and the other surgically delayed for administrative organizational reasons (AA group). Demographic variables related to treatment and fracture were analyzed in both groups, as well as the rates of surgical wound complications, general complications and mortality rate in the first 30 days, in the first year and more than one year after surgery. ResultsWe observed a surgical wound seroma and staining rate of 15.7% in the AA group and 9.6% in the ND group; and a surgical wound surface infection rate of 1.9% in the AA group and 0.8% in the ND group (p = 0.275). General complications occurred in 34.4% (AA group) and 29% (ND group). The 30-day mortality rate was 4.8% in the AA group and 1.9% in the ND group (p = 0.081). ConclusionWe found no statistically significant differences in patients delayed for administrative reasons in terms of mortality and surgical wound and general complication rates. Although the proportion of surgical wound complications and 30-day mortality was higher in the AA group versus the ND group.

Assessment of MRI and Ultrasound Screening for Tethered Cord Syndrome in Patients Diagnosed With Esophageal Atresia/Tracheoesophageal Fistula

IntroductionInfants with esophageal atresia and/or tracheoesophageal fistula (EA/TEF) undergo screening for tethered cord syndrome (TCS) via ultrasound and magnetic resonance imaging. Existing literature lacks data to guide optimal timing of screening and magnetic resonance imaging (MRI) is often delayed until 3-6 mo of age, when it is frequently forgotten. Detethering surgery has a high rate of success in patients with TCS and is often performed prophylactically due to potential irreversible deficits. This study aims to improve screening procedure for infants with EA/TEF. MethodsA retrospective chart review was done of all EA/TEF patients treated over 6 y (n = 79). The study examined how often each imaging modality was performed and identified a TCS lesion, as well as age of screening/surgical intervention. ResultsScreening for TCS was done with MRI 58% of the time and US 15% of the time. However, 38% of patients did not undergo any screening. Out of the patients with TCS on MRI (n = 19, 41.3%), 73.7% had neurosurgery. Of patients who underwent ultrasound (US) (n = 12), nine patients also had MRI later: two reported TCS lesions and subsequently had neurosurgery. Surgical infection rates and complications were 0/14. ConclusionsMRI demonstrated a higher rate of detecting TCS lesions than US, and patients with TCS frequently had detethering. Patients with ≥3 VACTERL or vertebral anomalies had a higher incidence of TCS on MRI. Patients with vertebral anomalies reported false negative ultrasounds in two cases, suggesting the potential superiority of MRI screening in this subgroup. A third of children did not undergo any imaging and this will require a process improvement.

Antiviral Treatment for Hepatitis C Is Associated With a Reduced Risk of Periprosthetic Joint Infection: A Meta-Analysis of Observational Studies

BackgroundRecently, preoperative antiviral therapies for hepatitis C virus (HCV) have become available for total joint arthroplasty (TJA) patients. The objective of this meta-analysis is to investigate the impact of anti-HCV treatment on the incidence of postoperative complications after primary TJAs. MethodsWe searched PubMed, EMBASE, Scopus, Web of Science, and Cochrane Library databases for relevant studies from inception to March 5, 2022. The pooled odds ratios with 95% CI of the risk of postoperative complications were calculated using the random effects model. Subgroup analyses were conducted on the basis of surgery type, antiviral regimes, and duration of follow-up. ResultsEight retrospective cohort studies fulfilled the inclusion and exclusion criteria, involving 9,703 subjects. Overall, antiviral therapy for HCV was associated with a reduced risk of all-type complications and surgical complications. Moreover, we found that HCV-infected patients without treatment had substantially higher rates of periprosthetic joint infection at any surgery type and follow-up time point. There was a tendency for favoring a lower pooled revision/reoperation rate and mechanical complication rate in treated patients compared with untreated patients, but the differences failed to reach statistical significance. When limiting analysis to patients receiving preoperative direct acting antiviral-based therapy, untreated patients still had a higher surgical complication rate and joint infection rate. ConclusionThis meta-analysis demonstrated that antiviral therapy for HCV appears to be associated with a reduced risk of surgical complications in TJA patients, particularly periprosthetic joint infection. Thus, direct-acting antiviral therapy could be recommended for patients diagnosed with HCV.

The UK Foot and Ankle COVID-19 National Audit – Rate of COVID-19 Infection and 30 Day Mortality in Foot and Ankle Surgery in the UK

Category:Diabetes; OtherIntroduction/Purpose:The primary objective was to determine the incidence of COVID-19 infection and 30-day mortality in patients undergoing foot and ankle surgery during the global pandemic. Secondary objectives were to determine if there was a change in infection and complication profile with changes introduced in practice.Methods:Design: Multicentre retrospective national audit. Setting: UK-based study on foot and ankle patients who underwent surgery between the 13th January to 31st July 2020 - examining time periods pre- UK national lockdown, during lockdown (23rd March to 11th May 2020) and post-lockdown. Participants: All adult patients undergoing foot and ankle surgery in an operating theatre during the study period included from 43 participating centres in England, Scotland, Wales and Northern Ireland. Main Outcome Measures: Variables recorded included demographics, surgical data, comorbidity data, COVID-19 and mortality rates, complications, and infection rates.Results:6644 patients were included. In total 0.52% of operated patients contracted COVID-19 (n=35). The overall all cause 30- day mortality rate was 0.41%, however in patients who contracted COVID-19, the mortality rate was 25.71% (n=9); this was significantly higher for patients undergoing diabetic foot surgery (75%, n=3 deaths). Matching for age, ASA and comorbidities, the OR of mortality with COVID-19 infection was 11.71 (95% CI 1.55 to 88.74, p=0.017). There were no differences in surgical complications or infection rates prior to or after lockdown, and amongst patients with and without COVID-19 infection. After lockdown COVID-19 infection rate was 0.15% and no patient died of COVID-19 infection.Conclusion:COVID-19 infection was rare in foot and ankle patients even at the peak of lockdown. However, there was a significant mortality rate in those who contracted COVID-19. Overall surgical complications and post-operative infection rates remained unchanged during the period of this audit. Patients and treating medical personnel should be aware of the risks to enable informed decisions.

Predisposing Factors for 30-Day Complications Following Leg Amputation

Category:Trauma; Ankle; Diabetes; OtherIntroduction/Purpose:While amputation rates and amputation-related morbidity and mortality have been established for select populations, the impact of general demographic factors on postoperative surgical complications remains little studied. This study aims to analyze the influence of numerous demographic variables on specific surgical complications.Methods:We extracted data from the American College of Surgeons' National Surgical Quality Improvement Program database from 2012 to 2017 and searched for leg amputations using CPT codes 27881, 27882, 27884, and 27886, identifying 4,162 patients. The association of 29 demographic variables with 4 complications (surgical infection, additional service, deep vein thrombosis [DVT], and sepsis) was analyzed using t tests or chi-squared tests. A logistic regression allowed determination of independent risk factors for each outcome, based on results from the bivariate analyses. Variables found to have P < 0.2 on bivariate analysis were subsequently included in the multivariate analysis of the corresponding surgical complication.Results:Preoperative open, 'contaminated,' or 'dirty/infected' wounds, longer intraoperative times, development of sepsis prior to surgery, and admission of patients directly from home or from another hospital's emergency room were found to influence postoperative surgical infection rates. An individual's height, weight, total length of hospital stay, ethnicity, the presence of preoperative open or infected wounds, and wounds classified as 'dirty/infected' preoperatively affected postoperative additional service incidence. Preoperative congestive heart failure and large decreases in body weight, as well as a patient's total length of hospital stay, influenced postoperative DVT rates. A patient's preoperative functional heath status, total length of hospital stay, amputations conducted as emergency cases, as well as preoperative acute renal failure, open or infected wounds, sepsis, 'contaminated' or 'dirty/infected' wounds, impacted postoperative sepsis rates.Conclusion:Understanding these risk factors may allow providers to anticipate and address higher rates of complications in certain patient populations.

Comparing Infection Rates from Using Different Surgical Preparation Solutions and Techniques in Foot &amp; Ankle Elective Surgery

Category:OtherIntroduction/Purpose:Surgical site infection (SSI) after Foot & Ankle surgery ranges from 1.2% to 13.2%, higher than any other elective orthopaedic procedure. Infection is of concern for the patient and expensive for the healthcare system. SSI is multifactorial and can be divided into host-related and perioperative factors. Skin preparation is one of the key peri-operative factors in reducing SSI. The current literature supports a combined chlorhexidine and alcohol preparation technique, although there is some conflicting evidence. Most studies to date have used proxy outcomes such as growth from swabs shortly after skin preparation. There are no large scale studies which have looked at definitive clinical outcomes such as the rate of postoperative SSI.Methods:A retrospective review of data was undertaken for two longitudinal cohorts which were using two different skin preparation solutions and techniques due to a change in hospital protocol. Each cohort was continuous and derived from the same overall populationIn cohort 1, Povidine-Iodine (Betadinetm) followed by Alcoholic Chlorhexidine was used on swabs (Double prep group). In cohort 2, 2 Alcoholic Chlorhexidine was used in a prep stick applicator. Standard criteria for diagnosing surgical site infection were used. All open injuries, procedures for ongoing infection, amputations for osteomyelitis /diabetic foot and COVID- 19 positive cases were excluded.Results:After applying standard exclusion criteria, 919 elective F&A procedures in the Double prep group and 491 procedures were included for the Single prep groupAs these were continuous longitudinal cohorts of large scale from the same population, there is a justifiable presumption of group matchingIn cohort 1 there were 15 superficial infections (1.6%) and 3 deep (0.3%). In cohort 2 there were 18 superfical infections (3.6%) and 1 deep (0.3%). The total infections in cohort 1 were 18 (2%) and 19 in cohort 2 (3.9%)There was an increase in superficial, and therefore total infection rates, in the single prep group compared to the double prep group. These increases were statistically significant; p <0.05 with regards to superficial infection and total infection rates in the single prep group.Conclusion:Double skin preparation, with Povidone-Iodine followed by alcoholic Chlorhexadine, statistically significantly decreases foot and ankle surgical infection rates as compared to a single alcoholic chlorhexidine skin preparation

The Management Outcomes of Maxderm Hydrocolloid Dressing Compared to Povidone Iodine Dressing Post Elective Cesarean Section Operations in Omdurman Maternity Hospital

Background: Dressing of post-surgical procedures was mainly dependent on Povidone iodine and saline gauze dressing, with longer hospital stay and more frequent dressing times which lead to increase surgical sites infection rates. Patient and Methods: This study is an observational prospective comparative cross-sectional hospital-based study, was conducted at Omdurman Maternity Hospital from November 2020 till August 2021. Data were collected by standardized questionnaire and analyzed by using SPSS version 20. Results: A total of 196 patients who satisfied the inclusion criteria were included in the study,(95) patients were undergone a povidone iodine dressing and (101) patients were on Hydrocolloid dressing. The mean age of recruited patients was found to be 31 ± 5.6 SD years; the age range was (15-47) years. The most encountered symptom in day zero and day 7 was abdominal pain (89%), which was more in povidone iodine dressing patients (50%, p value &lt; 0.0001). The most encountered symptom in day two was the abdominal pain (34.5%) similarly; it was more in povidone iodine dressing group (25%, p value &lt; 0.0001). The most encountered sign in day seven and day 14 was surgical site tenderness (40%, 32% respectively), and it found to be more in povidone iodine dressing group in days seven (27%, p value 0.008) and day 14 (24%, p value 0.0001). P value was also scientifically significant in wound exudate and Fever, as Povidone iodine dressing showed higher percentages compared to hydrocolloid dressing. 17% of patients showed complete healing days 0f &lt;6 days, 87% of them were of hydrocolloids dressing type (P value &lt; 0.0001). Sixty percent of Hydrocolloid dressing patients retained their activity within (8-14) days postoperatively with significant satisfaction and 53% of povidone iodine patients retained their more than 2 weeks postoperative (P value &lt; 0.0001). The mean total cost of dressing including the dressing frequency and nurse feasting hydrocolloid dressing ........

SP7.2.1 Simultaneous intestinal surgery does not increase complication or recurrence rates after complex abdominal wall reconstruction

Abstract Aims To compare post-operative outcomes in patients undergoing elective complex abdominal wall reconstruction (CAWR) alone vs. CAWR plus simultaneous intestinal surgery. Methods All patients undergoing elective CAWR over a 10-year period in our unit were identified from a prospectively maintained database and divided into those who had concomitant intestinal surgery (resection, ileoanal-pouch formation, stoma reversal, etc) and those who did not. Simple adhesiolysis, cholecystectomy and gynaecological procedures were not classed as ‘intestinal surgery’. Differences between groups were determined using the paired-t test and the (n-1) Chi-squared test. Results 59 patients underwent elective CAWR, 16 with intestinal surgery and 43 without. The two groups had similar baseline demographics with no significant differences in age, BMI, sex or hernia size. The commonest post-operative complications were pneumonia (33.9%) and wound infections (25.4%) but there were no significant differences in any complication between groups. There was zero 30 and 90 day mortality in either group. The mean operating time in the intestinal group (IG) was significantly longer compared to the CAWR-only group (5.4 +/- 1.3hrs vs 4.1 +/- 1.8hrs, p = &amp;lt;0.05). There was no statistically significant difference between groups in rates of surgical site occurrence (37.5% IG vs 55.81% CAWR-only), mesh infections (0% IG vs 6.98% CAWR-only) or recurrent hernia (6.24% IG vs 9.30% CAWR-only) over a median follow up of 3.0 (0.1-7.8) years. Conclusion Performing simultaneous intestinal surgery during complex abdominal wall repair is safe and does not increase the risk of recurrence or mesh infections in a specialist abdominal reconstruction unit.

980 Technological Innovations in The Management of Pressure Ulcers: A Systematic Review and Discussion

Abstract Aim Pressure ulcers (PUs) affect over 700,000 patients per annum and are associated with an up to fourfold increase in mortality rate in older populations with complex pathologies. NICE guidelines for PU management involve a combination of low-grade technological interventions, including dressings and foam mattresses, while technology-centric therapies are not offered. The aim of this systematic review is to evaluate the effectiveness of any novel and high-grade technological PU interventions. Method The PubMed, Embase (via Ovid), Web of Science and CINAHL databases were electronically searched using free-text and MeSH search strings. Results evaluating the type of technological intervention, outcome measures and wound healing rates, duration of hospital stay, requirement for surgical debridement, infection and mortality rates were methodically assessed. Results An initial search identified 900 articles. Using the PRISMA guidance, 25 studies were included, encompassing 845 patients. 28 novel modalities of high-grade innovations were identified, with distinguished technologies including smart wireless bandages and 3D-printed wound repair scaffolds. Overall, 92.8% of devices demonstrated an improvement in wound healing (P &amp;lt; 0.05). A novel framework was created from the different innovations identified to approach adopting innovation in PU management. Conclusions The majority of high-technology innovations identified in this systematic review significantly improve PU healing, thus offering an additional pathway to standard care. Given the annual cost of PUs (£531 million), it is vital innovative technologies are considered as the NHS transitions into a digital age. Therefore, further studies are essential and recommended to evaluate the potential benefit of the promising, innovative technologies identified.

The evolution of surgical virtual education and telementoring: One surgeon's journey

The first era of the global proliferation of surgical advancements involved surgical infection rate and technique breakthroughs by Lister, Halsted, and others. This was propagated by letters, academic papers, and international visits. While success was achieved, it was at a suboptimal pace. In the current era of minimally invasive surgical approaches, these methods are inadequate. This paper chronicles the development and application of virtual learning and telementoring as force multipliers to speed procedural adoption and proliferation.

891. Is Post-discharge Surveillance of Surgical Patients Really Worth It? Results Observed in Three Years of a Multicenter Study

BackgroundSurgical site infections (SSIs) can account for 25% of all nosocomial infections and contribute significantly to the economic burden resulting from infectious complications. To control this problem, an active surveillance program with the feedback of SSI rates to surgeons can reduce subsequent rates by up to 40%, since 19% to 65% of these infections are diagnosed after patient discharge. However, there is no standard method for conducting surveillance outside the hospital and the best methodology is still unknown. For many hospitals, SSI surveillance has three main objectives: to feedback surgeons with their SSI rates; to evaluate SSI rates over time, identifying outbreaks; and to compare data among different institutions. This study aims to answer the crucial question: is surveillance after patient discharge worthwhile?MethodsProspective surveillance according to the National Healthcare Safety Network (NHSN) protocol of the Centers for Disease Control and Prevention (CDC) at Hospital Lifecenter, Hospital Madre Teresa and Hospital Universitário Ciências Médicas, tertiary care centers, which serve the metropolitan area of Belo Horizonte, Brazil. The data were collected between Jan/2017 and Dec/2019.ResultsIn almost three years of study, the infection rate data were calculated with and without surveillance. The monthly analysis by clinic showed that the inclusion of post-discharge patients in the computed rates increases its value, but not significantly. Of 22.009 patients analyzed, in Lifecenter Hospital, 229(1%) had SSI. This percentage refers to the infection rate with the post-discharge survey, while the rate of surgical infection without vigilance corresponds to 202(0,9%) (Table 1). The surveillance for Madre Teresa, those numbers were: 29.770, 382(1,3%) and 351(1,2%), respectively (Table 2). In Hospital Universitário Ciências Médicas: 20.286, 447 (2,2%) and 215(1,1%) (Table 3).Table 1 - Surgical site infection: data with and without post-discharge surveillance.

Hospital Universitário Ciências Médicas (Jan/ 2017 to Dec/2019): month-by-month analysis. ConclusionSSI post-discharge surveillance is indicated only for specific procedures. However, once the endemic curve with the infection rate did not change with the inclusion of post-discharge SSI, the study strongly suggests that surveillance after the discharge of the surgical patient is not necessary.Graph 1 - Surgical site infection: rates with and without post-discharge surveillance.

888. Improving outcomes with revised preoperative universal decolonization protocol

BackgroundIn order to improve outcomes, including reduced surgical infection rate and costs, a revised universal preoperative decolonization protocol was implemented on a trial basis.MethodsIn a 12 month before and after study at a public teaching hospital in southern California, an alcohol based nasal antiseptic was introduced in place of nasal povidone iodine (PVI) for all surgical patients pre-operatively, paired with chlorhexidine (CHG) bathing which was already in place. All surgical procedures were included, the most common being cholecystectomy, cesarean section and hip fracture. The alcohol nasal antiseptic was selected to replace the PVI nasal antiseptic based on efficacy, staff preference and cost. At the same time, surgical team members began self-application of the alcohol nasal antiseptic each day prior to surgical procedures. This was not mandatory and compliance was not tracked, though informal feedback and observation revealed most surgical team members were applying the nasal antiseptic prior to cases daily.ResultsIn comparison to the 6 month baseline period where there were 27 SSI in 1188 procedures, during the 6 month study period there were 10 SSI in 1253 procedures, representing a 63% reduction (p=.0162) for all types of procedures. We have observed a reduction of 17 SSIs in 2019, compared to the previous year, during the 6 months period. That means a saving of $589,420 during the same period.ConclusionPreoperative universal decolonization with alcohol based nasal antiseptic in place of nasal PVI, paired with CHG bathing, was effective in reducing SSI rate and associated costs. Further study is needed to measure and assess the impact of surgical team member nasal decolonization on patient infection risk and rate.Disclosures All Authors: No reported disclosures

889. Improving patient compliance with preoperative universal decolonization to reduce surgical infection rate and costs

BackgroundIn order to address spine patient non-compliance with preoperative nasal decolonization, a trial was undertaken to replace nasal povidone iodine (PVI) with alcohol based nasal antiseptic paired with chlorhexidine (CHG) bathing for all spine fusion and laminectomy patients for a period of three months.MethodsIn addition to preoperative CHG bathing already in place, an alcohol based nasal antiseptic was applied to the nose of all spine surgery fusion and laminectomy patients within one hour of surgery instead of the PVI nasal antiseptic that had been in use previously.ResultsAfter switching the alcohol based nasal antiseptic, there was a reduction in surgical site infections (SSI) of 64% from 0.58 to 0.21/100 spine fusion procedures and a reduction in SSI of 100% from 0.46 to 0.00/100 laminectomy procedures. This represents an estimated cost avoidance of $127K associated with infections prevented. There was also a $37K cost savings resulting from switching from nasal PVI to alcohol based nasal antiseptic, with patients reporting greater satisfaction.ConclusionUniversal preoperative decolonization for spine fusion and laminectomy patients using an alcohol based nasal antiseptic and CHG bathing resulted in reduced infection rates and associated costs, reduced nasal antiseptic cost and improved patient satisfaction.Disclosures All Authors: No reported disclosures

Incidence of surgical site infection in colon surgery according to RENAVE methodology: Prospective study 2017–2019

BackgroundNavarra Hospital Complex has renovated its healthcare-associated infections surveillance and control methods meeting the requirements of the Spanish National Epidemiologic Surveillance Network. Surgical site infections are one of the most relevant adverse outcomes, being the colon surgery one of the mandatory monitored procedures. This system will ease, not only the yearly estimation of the hospital surgical infection rates, but also its comparison at national and European levels. Methods416 patients underwent surgery between 2017 and 2019. Clinical variables were gathered during the patient hospitalization and up to 30 days from surgery, stratifying the cases by their NHSN (National Health Safety Network) surgical infection risk index. A univariant descriptive analysis was performed and outcome indicators were estimated. ResultsThe cumulative incidence was 10.6%, with 44 cases. The rates were higher among the high-risk subgroups: 25.0% and 42.9%, respectively, for NSHN index categories 2 and 3. ConclusionsThe incidence was similar to the ones found in other studies carried out in analogous conditions. However, the methodologic variability makes it difficult to compare results.

Recommendations for patient management after manual reduction of incarcerated inguinal hernia: a literature review

Introduction: Topic of this review is to provide a systematic overview of the current evidence on the management of patients after manual reduction of an incarcerated inguinal hernia. Methods: Available literature regarding incarcerated or strangulated inguinal hernias published until March 2019 was obtained and reviewed. 32,021 papers were identified, of which only 20 were of a sufficient value to be used in this review. Results: The terms ‘incarcerated’ and ’strangulated’ are used interchangeably in the literature making separate analysis of these two entities almost impossible, although manual reduction is very unlikely to be successful when the hernia has strangulated contents. Following successful manual reduction, mesh repair is generally superior compared to pure tissue repair with regard to recurrence rates. Nevertheless, mesh repair is associated with a significant increase in the surgical site infection (SSI) rate, especially when bowel necrosis is present. The laparoscopic approach provides the benefits of avoiding an unnecessary laparotomy and reducing associated morbidity, but it does require the availability of appropriate equipment and an appropriately skilled surgical team. Conclusion: A mesh repair is generally superior to a pure tissue repair in the surgical management of emergency inguinal hernias, reducing the recurrence rate, but can be associated with an increased risk of SSI depending on the level of contamination. The laparoscopic approach is recommended if an experienced surgical team and necessary equipment are available.
