Objective: Antimicrobial prophylaxis is administered perioperatively to prevent surgical site infections. However, in patients who have already received antibiotics for the treatment of active infections prior to surgery, the risks and benefits of administering prophylactic antibiotics are unknown. We aimed to assess the necessity of perioperative prophylactic antibiotic administration in patients receiving antibiotic treatment for active infections. Method: This was a retrospective, chart-review cohort study. Between January 2018 to May 2018, adult patients who underwent inpatient surgery at the University of Illinois Hospital and Health Sciences System, and were prescribed prophylactic antibiotics based on institutional protocol, while receiving antibiotic treatment within 48 hours prior to surgery, were included in the study. The primary endpoint was the rate of duplicative antibiotic therapy, which was defined as the administered prophylactic antibiotic (1) exhibiting similar or narrower bacterial coverage as the treatment antibiotic(s), and (2) given within the dose interval of the treatment antibiotic(s). Results: A total of 158 patients were included in the study, of which 70 (44.3%) received duplicative antibiotic therapy, whereas 88 (55.7%) did not. Differences in the incidence of acute kidney injury, C. difficile infection, and surgery site infections were not statistically significant between the two groups. Conclusion We found that it was common for patients receiving therapeutic systematic antibiotics to perioperatively be prescribed additional prophylactic antibiotics at our institution. However, additional prophylactic antibiotics can be unnecessary in decreasing the incidence of surgical site infections.

The Impact

<p>Surgical site infections (SSIs) are a subset of a larger group of infections that are known as hospital acquired infections (HAis). SSIs are a huge financial burden, costing billions of dollars in excess hospital charges every year. There is a considerable amount of evidence-based practice recommendations that can help reduce the incidence of SSIs. Research has supported the efficacy of preoperative antibiotic prophylaxis when appropriately selected and timed according to published guidelines. In addition to these measures, re-dosing of antibiotics must occur for those procedures that last more than four hours in order to continue to maintain tissue perfusion throughout the surgical procedure. The purpose of this study was to evaluate the timely administration, appropriate selection, and dosage of preoperative prophylactic antibiotics in surgical patients in one community hospital. A retrospective research design was used to obtain information on 100 randomly selected colon, hysterectomy, total hip and knee arthroplasty cases. Data were collected on those surgical procedures that occurred between October 1, 2010 and March 31 , 2011. During this time period, there were eight documented SSIs, three involving an organ space, and five that were superficial. In more than half of the colon and hysterectomy cases, the prophylactic antibiotic was administered less than 30 minutes before surgical incision, and in more than half of the total hip and total knee arthroplasty cases, antibiotic administration was between 30-60 minutes. All the procedures met the SCIP recommendations for timing and selection of prophylactic antibiotic. This study suggests that to ensure adequate tissue perfusion prior to surgical incision, the antibiotic should be administered in the preoperative holding unit, immediately prior to transfer to the operating room. This would assure that the antibiotic is given 30-60 minute timeframe, thus reducing the potential for the development of a SSI. Recommendations for further research and advanced nursing practice are discussed.</p>

OBJECTIVE Guidelines recommend antimicrobial prophylaxis (AMP) preoperatively for "clean" spinal and cranial surgeries, while dose and timing remain controversial. The use of multiple-dose AMP for such surgeries is under debate in the pediatric context. In this clinical study, the authors aimed to compare single-dose with multiple-dose prophylactic antibiotic usage in cranial and spinal neurosurgical interventions of pediatric patients. METHODS All neurosurgical patients aged 28 days to 18 years who underwent surgery at a single tertiary center were assessed. Three cohorts (noninstrumented clean spinal, noninstrumented cranial, and instrumented cranial interventions), each of which comprised two 50-patient arms (i.e., single-dose AMP and multiple-dose AMP), were included after propensity score–matched retrospective sampling and power analysis. Records were examined for surgical site infections. Using a previously published meta-analysis as the prior and 80% acceptance of equivalence (margin of OR 0.88–1.13), logistic regression was carried out for the total cohort and each subcohort and adjusted for etiology by consideration of multiple-dose AMP as reference. RESULTS The overall sample included 300 age- and sex-matched patients who were evenly distributed in 3 bi-arm cohorts. There was no statistical intercohort difference based on etiology or type of operation (p < 0.05). Equivalence analysis revealed nondiscriminating results for the total cohort (adjusted OR 0.65, 95% CI 0.27–1.57) and each of the subcohorts (noninstrumented clean spinal, adjusted OR 0.65, 95% CI 0.12–3.44; noninstrumented cranial, adjusted OR 0.52, 95% CI 0.14–2.73; and instrumented cranial, adjusted OR 0.68, 95% CI 0.13–3.31). CONCLUSIONS No significant benefit for multiple-dose compared with single-dose AMPs in any of the pediatric neurosurgery settings could be detected. Since unnecessary antibiotic use should be avoided as much as possible, it seems that usage of single-dose AMP is indicated.

Hip And Knee Arthroplasty

Abstract Background Following concerns regarding the emergence of Clostridium difficile infection in 2010, we changed antibiotic prophylaxis in patients undergoing primary hip and knee arthroplasty from cefuroxime to flucloxacillin and single-dose (SD) gentamicin. A subsequent perceived increase in the incidence of post-operative acute kidney injury (AKI) led us to evaluate the AKI incidence between different prophylactic antibiotic regimes used at our centre. Methods We examined the incidence of AKI as defined by Kidney Disease: Improving Global Outcomes criteria in 1588 patients undergoing primary hip or knee arthroplasty from January 2010 to January 2015. Patients received the following prophylactic antibiotic regimes: 8 g flucloxacillin in four divided doses and SD gentamicin 1.5 mg/kg ideal body weight (IBW; maximum dose 120 mg; n = 400), 8 g flucloxacillin alone in four divided doses (n = 400), SD cefuroxime (n = 400), triple-dose (TD) cefuroxime (n = 188) and teicoplanin with SD gentamicin 1.5 mg/kg IBW (n = 200). Results The incidence of AKI was as follows: flucloxacillin and gentamicin (13%); flucloxacillin alone (8.5%); SD cefuroxime (2%); TD cefuroxime (0.5%); and teicoplanin and gentamicin (3%). Of the six patients who developed Stage 3 AKI, all were in the flucloxacillin and gentamicin group. The odds ratio for the development of AKI derived from a binary logistic regression model was highest in the flucloxacillin and gentamicin group [7.79 (95% confidence interval 3.54–17.14), P &lt; 0.0001]. Conclusions Our findings suggest that the use of prophylactic high-dose flucloxacillin and gentamicin should be used with caution in patients undergoing primary hip or knee arthroplasty without a clear advantage in reducing surgical site infections given the association with increased rates of AKI.

Animal Bites

There is controversy regarding the timing of repair and the use of prophylactic antibiotics in patients with animal bites to the head and neck. In this paper we review our experience with such wounds, and address surgical management and the use of prophylactic antibiotic therapy. A retrospective review of the medical records of 29 patients with animal bites to the head and neck was conducted. All patients were seen and treated at a large teaching hospital in Houston, Texas over an 18-month period. Seventy-six percent of our patients were 12 years old or younger. Most came to the emergency room soon after sustaining their injuries, and their wounds were repaired primarily with favorable results. There were no cases of wound infection. Ninety percent were treated with prophylactic antibiotics. The wounds of the 10% of patients who did receive antibiotics were similar to those of the other patients and healed well without infection. Wounds resulting from animal bites to the head and neck can be repaired primarily when treated shortly after injury. Further prospective, randomized studies are recommended to evaluate the effectiveness and necessity of prophylactic antibiotic therapy in this patient population.

Background Surgical site infections (SSIs) are the leading cause of hospital-acquired infections and are associated with substantial health care costs, with increased morbidity and death. The Surgical Care Improvement Project (SCIP) contains standards that are nationally reported with the aim of improving patient outcomes after surgery. Our institution's standards for antimicrobial prophylaxis in the perioperative period are more stringent than these measures and may be considered “beyond SCIP.” The 4 elements of appropriate antimicrobial prophylaxis are timing, antibiotic selection, dosing, and intraoperative redosing. Objective To quantify antimicrobial SSI prophylaxis compliance in accordance with institutional standards and to identify potential opportunities for improvement. Methods Patients aged 18 years or older were included if they had an SSI between January 1, 2009, and June 30, 2010, according to the database maintained prospectively by the Infection Prevention and Control Unit. Adherence to our institution's practice standards was assessed through analysis of antibiotics administered—timing in relation to the incision, closure, and tourniquet inflation times for the procedure and antibiotic selection, dose, and redosing. Results Overall noncompliance with all 4 elements of antimicrobial prophylaxis was 75.4% among the 760 cases. Repeat dosing had the greatest noncompliance (45.1%); antibiotic selection had the lowest incidence of noncompliance (10.8%). Conclusions Noncompliance existed in each element of antimicrobial SSI prophylaxis, with antibiotic redosing leading in noncompliance. With the implementation of tools to assist the surgical team in following institutional standards, noncompliance will likely decline and additional research opportunities will exist.

Abstract Background Although sepsis is a major health problem, data on sepsis epidemiology are scarce. The aim of this study was to assess the incidence of sepsis, based on clinical findings in all adult patients treated with intravenous antibiotic in all parts of all hospitals in an entire population. Methods This is a retrospective chart review of patients ≥18 years, living in 2 regions in Sweden, who were started on an intravenous antibiotic therapy on 4 dates, evenly distributed over the year of 2015. The main outcome was the incidence of sepsis with organ dysfunction. The mean population ≥18 years at 2015 in the regions was 1275753. Five hundred sixty-three patients living in the regions were started on intravenous antibiotic treatment on the dates of the survey. Patients who had ongoing intravenous antibiotic therapy preceding the inclusion dates were excluded, if sepsis was already present. Results Four hundred eighty-two patients were included in the study; 339 had a diagnosed infection, of those, 96 had severe sepsis according to the 1991/2001 sepsis definitions, and 109 had sepsis according to the sepsis-3. This is equivalent to an annual incidence of traditional severe sepsis of 687/100000 persons (95% confidence interval [CI], 549–824) or according to the sepsis-3 definition of 780/100000 persons (95% CI, 633–926). Seventy-four patients had sepsis according to both definitions. Conclusions The incidence of sepsis with organ dysfunction is higher than most previous estimates independent of definition. The inclusion of all inpatients started on intravenous antibiotic treatment of sepsis in a population makes an accurate assessment of sepsis incidence possible.

Object Infection represents the most common serious complication of shunt surgery, and typically its incidence ranges between 5 and 15%, despite the use of systemic antibiotic agents. Because systemic antibiotic medications generally penetrate the cerebrospinal fluid (CSF) poorly, the authors investigated, in a controlled study, whether the addition of intraventricular antibiotic treatment decreases the incidence of perioperative infection in adult patients. Methods Data pertaining to all CSF shunt procedures conducted at the authors’ institution during an 11-year period were reviewed. Perioperative infection was defined as culture-positive CSF and the clinical presence of infection-related symptoms occurring within 90 days of surgery. All patients underwent intraoperative systemic antistaphylococcal antibiotic therapy. Before May 16, 1999, the senior author (R.H.S.) also administered 4 mg of gentamicin intraventricularly at surgery (Group I); thereafter, 10 mg of vancomycin was additionally administered (Group II). Other neurosurgeons at this institution did not use intraventricular antibiotic therapy, and their patients served as additional controls in identical time periods (Groups III and IV). A total of 802 shunt procedures were performed in 534 patients. Control infection rates were 5.4% (eight of 147) in Group I; 6.2% (nine of 145) in Group III; and 6.7% (18 of 267) in Group IV. With the combination of systemic antibiotic and intraventricular gentamicin and vancomycin (Group II), the infection rate fell significantly to 0.4% (one of 243). No complications were noted in association with intraventricular antibiotic administration. Conclusions The combination of intraventricular gentamicin and vancomycin with systemic antibiotic therapy significantly decreased the incidence of perioperative shunt infection. It is presumed that intraventricular antibiotic therapy extends prophylactic antibiotic coverage into the CSF and prevents bacterial seeding.

Abstract Introduction According to the Centers for Disease Control’s 2015 Hospital Acquired Infection Hospital Prevalence Survey, 1 in 31 hospital patients was infected with at least one nosocomial pathogen while being treated for unrelated issues. Many studies associate antibiotic administration with nosocomial infection occurrence. However, to our knowledge, there is little to no direct evidence of antibiotic administration selecting for nosocomial opportunistic pathogens. Aim This study aims to confirm gut microbiota shifts in an animal model of antibiotic treatment to determine whether antibiotic use favors pathogenic bacteria. Methodology We utilized next-generation sequencing and in-house metagenomic assembly and taxonomic assignment pipelines on the fecal microbiota of a urinary tract infection mouse model with and without antibiotic treatment. Results Antibiotic therapy decreased the number of detectable species of bacteria by at least 20-fold. Furthermore, the gut microbiota of antibiotic treated mice had a significant increase of opportunistic pathogens that have been implicated in nosocomial infections, like Acinetobacter calcoaceticus/baumannii complex, Chlamydia abortus, Bacteroides fragilis, and Bacteroides thetaiotaomicron. Moreover, antibiotic treatment selected for antibiotic resistant gene enriched subpopulations for many of these opportunistic pathogens. Conclusions Oral antibiotic therapy may select for common opportunistic pathogens responsible for nosocomial infections. In this study opportunistic pathogens present after antibiotic therapy harbored more antibiotic resistant genes than populations of opportunistic pathogens before treatment. Our results demonstrate the effects of antibiotic therapy on induced dysbiosis and expansion of opportunistic pathogen populations and antibiotic resistant subpopulations of those pathogens. Follow-up studies with larger samples sizes and potentially controlled clinical investigations should be performed to confirm our findings.

Abstract Background: Venous congestion in transplanted or replanted tissues remains a common and challenging complication of plastic and reconstructive surgery. The local application of medicinal leeches is effective in reducing postoperative venous congestion in skin flaps and restoring normal blood flow. However, leech therapy is associated with a number of risks, including infections; in order to digest blood, leeches have a symbiotic relationship with Aeromonas species in their gut. Aeromonas infections are associated with a dramatic decrease in flap salvage rates. This is why prophylactic antibiotic treatment and external decontamination of the leeches are widely recommended. Methods: We performed a single retrospective study of patients having undergone leech therapy between January 1st, 2010, and December 31st, 2018, at Amiens-Picardie University Hospital, France. Each patient’s medical history, clinical data, laboratory results, prophylactic antibiotic use, and complications were recorded.Results: A total of 37 patients (mean age: 47) had undergone leech therapy after reconstructive surgery. Antimicrobial prophylaxis was documented in 32 (84.6%) patients. However, there are no guidelines on the choice of prophylactic antibiotic treatment. Twenty-four of the 37 (64.8 %) patients had anemia (mean hemoglobin level: 8.5 (6-11.1) g/dL), and 13 of the 24 (54%) required a transfusion. Thirteen of the 37 patients (35.1%) had a post-operative infection mainly due to Aeromonas spp. (76.9%). Leech therapy was effective in 23 of the 37 patients (62%) overall and in 2 of the 10 patients (20%) with an Aeromonas infection. The association between Aeromonas infection and flap salvage failure was highly significant (p = 0.005).Conclusions: The results of the study emphasized that clinical bacteriologists and surgeons should be aware that leeches are potential sources of infection.

Surgical site infection after thyroid surgery is a less common incidence. Prophylactic antibiotic before surgery and empirical antibiotic therapy after surgery is a common practice in our country. But international guidelines do not suggest antibiotic in clean surgical procedure. Aim: To compare the incidence of surgical site infection after thyroid surgery with and without empirical antibiotic therapy. Method: It was a cross sectional study, done from July 2010 to December 2010 in 3 medical college hospitals in Dhaka city. Total 100 cases were included in this study, 50 cases for study in which only single prophylactic antibiotic used half an hour before operation, 50 cases for control in which 7 days antibiotic used per orally in addition to prophylaxis. Result: Among 100 cases male were 24 & female 76 (M: F= 1:3.2). Oldest patient was 56 yrs & youngest 21yrs. 47% patient operated for solitary thyroid nodule, 35% multinodular goiter & only 6% diffuse goiter. 47% patient was done hemithyroidectomy & only 7% total thyroidectomy. All the operations were completed within 2 hours where 40% within one hour. No surgical site infections were found in both study and control cases. Conclusion: There is no statistical difference between routine antibiotic use and no use of antibiotic after thyroid surgery. Bangladesh J Otorhinolaryngol; April 2016; 22(1): 15-20
