Abstract
» We aimed to determine the cost-effectiveness of different protocols of extended postoperative antibiotic prophylaxis (E-PAP) following adult spinal surgery. » Both stratified (randomized controlled trials only) and nonstratified (all studies) analyses demonstrated that E-PAP has no significant value in reducing the rate of surgical site infection (SSI), deep SSI, or superficial SSI. » Notably, the E-PAP protocols were associated with a significant increase in the length of hospital stay, resulting in an additional expenditure of $244.4 per episode for the E-PAP 72 hours protocol compared with PAP 24 hours and $309.8 per episode for the E-PAP >48 hours protocol compared with PAP <48 hours. » E-PAP does not demonstrate any significant reduction in the rate of SSIs following spine surgery. However, these extended protocols were significantly associated with an increase in the length of hospital stay and higher overall projected costs.

Abstract
Objective Closed-suction drains are commonly placed after thoracolumbar surgery to reduce the risk of post-operative hematoma and neurologic deterioration, and may stay in place for a longer period of time if output remains high. Prolonged maintenance of surgical site drains, however, is associated with an increased risk of surgical site infection (SSI). The present study aims to examine the literature regarding extended duration (≥24 h) prophylactic antibiotic use in patients undergoing posterior thoracolumbar surgery with closed-suction drainage. Methods This systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Relevant studies reporting the use of 24-h post-operative antibiotics compared with extended duration post-operative antibiotics in patients undergoing posterior thoracolumbar surgery with closed-suction drainage were identified from a PubMed database query. Results Six studies were included for statistical analysis, encompassing 1003 patients that received 24 h of post-operative antibiotics and 984 patients that received ≥24 h of post-operative antibiotics. The SSI rate was 5.16 % for the shorter duration group (24 h) and 4.44 % (p = 0.7865) for the longer duration group (≥24 h). Conclusions There is no significant difference in rates of SSI in patients receiving 24 h of post-operative antibiotics compared with patients receiving ≥24 h of post-operative antibiotics. Shorter durations of post-operative antibiotics in patients with thoracolumbar drains have similar outcomes compared to patients receiving longer courses of antibiotics. Shorter durations of antibiotics could potentially help lead to lower overall cost and length of stay for these patients.

Abstract
OBJECTIVE Large language models, such as chat generative pre-trained transformer (ChatGPT), have great potential for streamlining medical processes and assisting physicians in clinical decision-making. This study aimed to assess the potential of ChatGPT's 2 models (GPT-3.5 and GPT-4.0) to support clinical decision-making by comparing its responses for antibiotic prophylaxis in spine surgery to accepted clinical guidelines. METHODS ChatGPT models were prompted with questions from the North American Spine Society (NASS) Evidence-based Clinical Guidelines for Multidisciplinary Spine Care for Antibiotic Prophylaxis in Spine Surgery (2013). Its responses were then compared and assessed for accuracy. RESULTS Of the 16 NASS guideline questions concerning antibiotic prophylaxis, 10 responses (62.5%) were accurate in ChatGPT's GPT-3.5 model and 13 (81%) were accurate in GPT-4.0. Twenty-five percent of GPT-3.5 answers were deemed as overly confident while 62.5% of GPT-4.0 answers directly used the NASS guideline as evidence for its response. CONCLUSION ChatGPT demonstrated an impressive ability to accurately answer clinical questions. GPT-3.5 model's performance was limited by its tendency to give overly confident responses and its inability to identify the most significant elements in its responses. GPT-4.0 model's responses had higher accuracy and cited the NASS guideline as direct evidence many times. While GPT-4.0 is still far from perfect, it has shown an exceptional ability to extract the most relevant research available compared to GPT-3.5. Thus, while ChatGPT has shown far-reaching potential, scrutiny should still be exercised regarding its clinical use at this time.

Abstract
The authors outline a review of preoperative, intraoperative, and postoperative considerations surrounding adult spinal deformity. Preoperative management topics include imaging, hemoglobin A1c levels before spine surgery, osteoporotic management, and prehabilitation. Topics surrounding intraoperative management include the use of antibiotics, liposomal bupivacaine, and Foley catheters. The authors also discuss postoperative questions surrounding analgesia, nausea and vomiting, thromboembolic prophylaxis, and early mobilization. Throughout their discussion, the authors incorporate enhanced recovery after surgery protocols to hopefully lead to future discussions regarding optimizing complex spinal patients.

Abstract
BACKGROUND AND PURPOSE We aimed to determine whether an extended oral antibiotic prophylaxis protocol may reduce the rate of surgical site infection (SSI) in patients undergoing instrumented spinal fusion. PATIENTS AND METHODS This retrospective cohort study comprise 901 consecutive patients subjected to spinal fusion between September 2011 and December 2018 with a minimum 1-year follow-up. 368 patients operated on between September 2011 and August 2014 were administered standard intravenous prophylaxis. 533 patients operated on between September 2014 and December 2018 were administered an extended protocol with 500 mg of oral cefuroxime axetil every 12 hours (clindamycin or levofloxacin in allergic individuals) until the removal of sutures. SSI was defined following the Centers for Disease Control and Prevention criteria. The association between risk factors and the incidence of SSI was evaluated by odds ratio (OR) with a multiple logistic regression model. RESULTS The bivariate analysis showed a statistically significant association between SSI and the type of prophylaxis used ("extended"' = 1.7% vs. "standard" = 6.2%, p= 0.001), with a lower proportion of superficial SSIs with the extended regimen (0.8% vs. 4.1%, p = 0.001). The multiple logistic regression model showed an OR = 0.25 (95% confidence interval [CI] 0.10-0.53) for extended prophylaxis and an OR = 3.5 (CI 1.3-8.1) for non-beta-lactams antibiotics. CONCLUSION Extended antibiotic prophylaxis seems to be associated with a reduction in the incidence of superficial SSI in instrumented spine surgery.

Abstract
OBJECTIVES To describe the association between duration of antimicrobial prophylaxis (AMP) and 30-day surgical site infection (SSI), 7-day acute kidney injury (AKI), 90-day Clostridioides difficile infection (CDI), prolonged hospitalization, and 30-day reoperation after lumbar spine surgery for noninfectious indications, and to report adherence to current guidelines. DESIGN Survey. PARTICIPANTS AND SETTING The study cohort comprised 6,198 patients who underwent lumbar spine surgery for noninfectious indications across 137 Veterans' Health Administration surgery centers between 2016 and 2020. METHODS Used univariate and multivariate logistic regression to determine the association between type and duration of AMP with 30-day SSI, 7-day AKI, 90-day CDI, prolonged hospitalization, and 30-day reoperation. RESULTS Only 1,160 participants (18.7%) received the recommended duration of AMP. On multivariate analysis, the use of multiple prophylactic antimicrobials was associated with increased odds of 90-day CDI (adjusted odds ratio [aOR], 5.5; 95% confidence interval [CI], 1.1-28.2) and 30-day reoperation (aOR, 2.3; 95% CI, 1.2-4.4). Courses of antimicrobials ≥3 days were associated with increased odds of prolonged hospitalization (aOR,1.8; 95% CI, 1.4-2.3) and 30-day reoperation (aOR, 3.5; 95% CI, 2.2-5.7). In univariate analysis, increasing days of AMP was associated with a trend toward increasing odds of 90-day CDI (cOR, 1.4; 95% CI, 1.0-1.8 per additional day; P = .056). CONCLUSIONS Longer courses of AMP after lumbar spine surgery were associated with higher odds of CDI, prolonged hospitalization, and reoperation, but not with lower odds of SSI. However, adherence to the recommended duration of AMP is very low, hinting at a wide evidence-to-practice gap that needs to be addressed by spine surgeons and antimicrobial stewardship programs.

Abstract
Background Surgical site infections (SSI) in instrumented spine surgery remains as a major complication with increased morbidity. Although implementation of surgical safety checklists has been reported to lower the rates of SSI, reproducibility of these remain unclear. Objective The specific aim of this study was to explore the results of implementation of a SSI control protocol in regard to its efficacy in decreasing the rate of SSI. Methods A total of 140 instrumented spinal surgery cases between 2018 and 2021 were divided into two groups as Group 1 (checklist implemented) and Group 2 (control) and these were compared regarding SSI rates, patient rand surgery related factors, laboratory findings and infecting microorganisms. Results Ten SSIs were encountered in Group 1 (20.8%), whereas only nine in Group 2 (9.8%). Although not statistically significant (p > .05), these results highly favor the non-checklist implemented group regarding the development of SSI. A definitive infective microorganism could be identified in five out of 10 SSI in Group 1 and 6 out of nine in Group 2. Whereas only three out of 11 (27.3%) involved Gr (+) agents, rest of eight out of 11 (72.7%) involved Gr (-) agents. Discussion A failure in decreasing the SSI rate through the implementation of a SSI prevention checklist may be due to several factors pertaining to the study design, patient characteristics and the Gr (-) dominance in SSIs in our center. Nevertheless, this suggests that checklist implementation to prevent SSI in instrumented spine surgery may not be effective in all contexts.

Abstract
PURPOSE To determine whether the published literature supports the current practice of utilizing antibiotics postoperatively in spine surgery. METHODS A systematic review from PubMed and Cochrane Central Register of Controlled trials databases was performed. Search terms used: "Antibiotic Prophylaxis"[Mesh], antibiotic*, antibacterial*, "Spine"[Mesh], "Surgical Procedures, Operative"[Mesh]. Only comparative, clinical studies were included. Those studies with surgical site infection (SSI) criteria that were not similar to the CDC definition were excluded. A meta-analysis for overall SSI was performed. A subgroup analysis was also performed to analyze the outcomes specifically on instrumented groups of patients. A random-effects model was used to calculate risk ratios (RR). Forest plots were used to display RR and 95% confidence intervals (CI). RESULTS Thirteen studies were included (four Randomized-Controlled Trials, three prospective cohorts, and six retrospective). Three different perioperative strategies were used in the selected studies: Group 1: preoperative antibiotic administration (PreopAbx) versus PreopAbx and any type of postoperative antibiotic administration (Pre + postopAbx) (n = 6 studies; 7849 patients); Group 2: Pre + postopAbx ≤ 24 h versus Pre + postopAbx > 24 h (n = 6; 1982); and Group 3: Pre + postopAbx ≤ 48 h versus. Pre + postopAbx ≤ 72 h (n = 1; 502). The meta-analysis performed on Groups 1 and 2 did not show significant effects (RR = 1.27, 95% CI = 0.77, 2.09, and RR = 0.97, 95% CI = 0.64, 1.46, respectively). CONCLUSION A meta-analysis and comprehensive review of the literature show that the routine use of postoperative antibiotics in spine surgery may not be effective in preventing surgical site infections.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE The aim of the current investigation was to evaluate the impact of prolonged prophylactic systemic antibiotics (PPSA) on the development of surgical site infection rate (SSIR) in degenerative spine surgery. SUMMARY OF BACKGROUND DATA Surgical drains are utilized postoperatively in posterior spine surgery to help minimize the risk of seroma formation. Prophylactic antibiotics while drains are in place are frequently used to reduce SSIR, though the practice remains controversial. METHODS We performed a single center, retrospective review of all patients that underwent posterior spinal surgery for cervical and lumbar degenerative pathology over a 3.5 year period (January 2016-July 2019). Patients underwent a traditional open posterior midline procedure with postoperative placement of a subfascial surgical drain. Antibiotics were administered for the duration of the drain (PPSA group) or for 24 hours postoperatively (non-PPSA group). The number of surgical site infections, organism, and Clostridium difficile infections was recorded. RESULTS Three hundred thirty six patients were identified, 168 patients in the PPSA group and 168 in the non-PPSA groups. The overall SSIR was 5.36% (18/336). The SSIR for the non-PPSA and PPSA groups were 7.14% (12/168) and 3.57% (6/168), respectively (P = 0.146). While difference of SSIR between the groups was two-fold, it was not statistically significant. For the non-PPSA and PPSA groups, the SSIR for cervical (5.95% [5/84] vs. 2.38% [2/84], P = 0.443) and lumbar (8.33% [7/84], vs. 4.76% [4/84], P = 0.535) regions were not significantly different. C. difficile cases in the PPSA and non-PPSA groups were 1/168 and 0/168 respectively (P = 1.00). CONCLUSION Our series demonstrate a two-fold reduction of SSI with implementation of PPSA regimen. This benefit was demonstrated separately for both cervical and lumbar regions. Randomized trials and increase in sample size are warranted to elucidate the significance of PPSA in posterior spinal surgery.Level of Evidence: 3.

Abstract
OBJECTIVE Despite recommendations to discontinue prophylactic antibiotics after incision closure or <24 hours after surgery, prophylactic antibiotics are continued after discharge by some clinicians. The objective of this study was to determine the prevalence and factors associated with postdischarge prophylactic antibiotic use after spinal fusion. DESIGN Multicenter retrospective cohort study. PATIENTS This study included patients aged ≥18 years undergoing spinal fusion or refusion between July 2011 and June 2015 at 3 sites. Patients with an infection during the surgical admission were excluded. METHODS Prophylactic antibiotics were identified at discharge. Factors associated with postdischarge prophylactic antibiotic use were identified using hierarchical generalized linear models. RESULTS In total, 8,652 spinal fusion admissions were included. Antibiotics were prescribed at discharge in 289 admissions (3.3%). The most commonly prescribed antibiotics were trimethoprim/sulfamethoxazole (22.1%), cephalexin (18.8%), and ciprofloxacin (17.1%). Adjusted for study site, significant factors associated with prophylactic discharge antibiotics included American Society of Anesthesiologists (ASA) class ≥3 (odds ratio [OR], 1.31; 95% CI, 1.00-1.70), lymphoma (OR, 2.57; 95% CI, 1.11-5.98), solid tumor (OR, 3.63; 95% CI, 1.62-8.14), morbid obesity (OR, 1.64; 95% CI, 1.09-2.47), paralysis (OR, 2.38; 95% CI, 1.30-4.37), hematoma/seroma (OR, 2.93; 95% CI, 1.17-7.33), thoracic surgery (OR, 1.39; 95% CI, 1.01-1.93), longer length of stay, and intraoperative antibiotics. CONCLUSIONS Postdischarge prophylactic antibiotics were uncommon after spinal fusion. Patient and perioperative factors were associated with continuation of prophylactic antibiotics after hospital discharge.

Prophylactic postoperative measures to minimize surgical site infections in spine surgery: systematic review and evidence summary. Spine J 2020; 20:435-447. [PMID: 31557586 DOI: 10.1016/j.spinee.2019.09.013] [Citation(s) in RCA: 43] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2019] [Revised: 09/12/2019] [Accepted: 09/13/2019] [Indexed: 02/08/2023]
Abstract
BACKGROUND CONTEXT There are three phases in prophylaxis of surgical site infections (SSI): preoperative, intraoperative and postoperative. There is lack of consensus and paucity of evidence with SSI prophylaxis in the postoperative period. PURPOSE To systematically evaluate the literature, and provide evidence-based summaries on postoperative measures for SSI prophylaxis in spine surgery. STUDY DESIGN Systematic review, meta-analysis, evidence synthesis. METHODS A systematic review conforming to PRIMSA guidelines was performed utilizing PubMed (MEDLINE), EMBASE, and the Cochrane Database from inception to January 2019. The GRADE approach was used for quality appraisal and synthesis of evidence. Six postoperative care domains with associated key questions were identified. Included studies were extracted into evidence tables, data synthesized quantitatively and qualitatively, and evidence appraised per GRADE approach. RESULTS Forty-one studies (nine RCT, 32 cohort studies) were included. In the setting of preincisional antimicrobial prophylaxis (AMP) administration, use of postoperative AMP for SSI reduction has not been found to reduce rate of SSI in lumbosacral spine surgery. Prolonged administration of AMP for more than 48 hours postoperatively does not seem to reduce the rate of SSI in decompression-only or lumbar spine fusion surgery. Utilization of wound drainage systems in lumbosacral spine and adolescent idiopathic scoliosis corrective surgery does not seem to alter the overall rate of SSI in spine surgery. Concomitant administration of AMP in the presence of a wound drain does not seem to reduce the overall rate of SSI, deep SSI, or superficial SSI in thoracolumbar fusion performed for degenerative and deformity spine pathologies, and in adolescent idiopathic scoliosis corrective surgery. Enhanced-recovery after surgery clinical pathways and infection-specific protocols do not seem to reduce rate of SSI in spine surgery. Insufficient evidence exists for other types of spine surgery not mentioned above, and also for non-AMP pharmacological measures, dressing type and duration, suture and staple management, and postoperative nutrition for SSI prophylaxis in spine surgery. CONCLUSIONS Despite the postoperative period being key in SSI prophylaxis, the literature is sparse and without consensus on optimum postoperative care for SSI prevention in spine surgery. The current best evidence is presented with its limitations. High quality studies addressing high risk cohorts such as the elderly, obese, and diabetic populations, and for traumatic and oncological indications are urgently required.

Abstract
BACKGROUND Closed-suction drains are frequently used following posterior spinal surgery. The optimal timing of antibiotic discontinuation in this population may influence infection risk, but there is a paucity of evidence. The aim of this study was to determine whether postoperative antibiotic administration for 72 hours (24 hours after drain removal as drains were removed on the second postoperative day) decreases the incidence of surgical site infection compared with postoperative antibiotic administration for 24 hours. METHODS Patients undergoing posterior thoracolumbar spinal surgery managed with a closed-suction drain were prospectively randomized into 1 of 2 groups of postoperative antibiotic durations: (1) 24 hours, or (2) 24 hours after drain removal (72 hours). Drains were discontinued on the second postoperative day. The duration of antibiotic administration was not blinded. All subjects received a single dose of preoperative antibiotics, as well as intraoperative antibiotics if the surgical procedure lasted >4 hours. The primary outcome was the rate of complicated surgical site infection (deep or organ or space) within 1 year of the surgical procedure. RESULTS The trial was terminated at an interim analysis, when 552 patients were enrolled, for futility with respect to the primary outcome. In this study, 282 patients were randomized to postoperative antibiotics for 24 hours and 270 patients were randomized to postoperative antibiotics for 72 hours. A complicated infection developed in 17 patients (6.0%) in the 24-hour group and in 14 patients (5.2%) in the 72-hour group (p = 0.714). The superficial infection rate did not differ between the groups (p = 0.654): 9.6% in the 24-hour group compared with 8.1% in the 72-hour group. Patients in the 72-hour group had a median hospital stay that was 1 day longer (p < 0.001). At 1 year, patient-rated outcomes including leg and back pain and physical and mental functioning were not different between the groups. CONCLUSIONS The extension of postoperative antibiotics for 72 hours, when a closed-suction drain is required, was not associated with a reduction in the rate of complicated surgical site infection after posterior thoracolumbar spinal surgery.

Abstract
BASICS Postoperative surgical site infections of the spine have been described in up to 20% of patients and can result in serious consequences for the patient and substantial treatment costs. Typical bacteria often arise from skin or fecal flora. Various risk factors for infection have been described, including obesity, diabetes, high ASA scores, as well as intraoperative factors such as heavy blood loss, dural tears, or several revision procedures. Consequently, the prophylaxis with pre- and postoperative risk minimization is of particular importance. TREATMENT When an infection has developed, it is important to carry out early operative revision involving tissue debridement, lavage and acquiring microbiological samples for culture. If the infection presents early, the instrumentation can often be retained. Adjuvant measures such as negative pressure wound treatment may improve the outcome. In late-onset infections, due to the biofilm production on the instrument surface or in cases of implant loosening, one should attempt to remove the instrumentation, and in cases of instability replace it. This article deals with the current literature on the subject and provides an overview of the data with regard to peri- and postoperative infections.

Abstract
Background: Multiple measures prior to spine surgery may reduce the risks of postoperative surgical site infections (SSIs). Methods: The incidence of SSI following spinal surgery (including reoperations and readmissions) may be markedly reduced by performing less extensive procedures and avoiding fusion where feasible. Preoperative testing up to 3 weeks postoperatively should include other studies to limit the perioperative SSI risk; cardiac stress tests (e.g., older patients/cardiac comorbidities), starting tamsulosin in males over 60 (e.g. avoid urinary retention due to benign prostatic hypertrophy), albumin/prealbumin levels (e.g., low levels increase SSI risk), and HBA1C levels to identify new/treat known diabetics (normalize/reduce preoperative levels). Results: Other measures include the timely administration of preoperative antibiotics (e.g., cefazolin 2 g nonpenicillin allergic), one dose of gentamicin (adjusted dose/weight), nasal cultures for methicillin-resistant Staphylococcus aureus (patients/health-care workers), and bathing 2 weeks preoperatively with chlorhexidine gluconate 4% (not just night before/morning of surgery). Additionally, prior to surgery, the following medications that increase the bleeding risk should be stopped (e.g. for varying periods); anticoagulants, antiplatelet therapies (e.g., aspirin for at least 7–10 days), nonsteroidal anti-inflammatories (NSAIDS: timing depends on the drug), vitamin E, and herbal supplements. Additionally, avoiding elective spinal surgery in morbidly obese patients and recognizing other major medical contraindications to spinal surgery should help reduce infection, morbidity, and mortality rates. Conclusions: Appropriate preoperative and intraoperative prophylactic maneuvers may reduce the risk of postoperative spinal SSI. Specific attention to these details may avoid infections and improve outcomes.

Influence of a strictly perioperative antibiotic prophylaxis vs a prolonged postoperative prophylaxis on surgical site infections in maxillofacial surgery. Infection 2017; 46:225-230. [PMID: 29250713 DOI: 10.1007/s15010-017-1110-4] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2017] [Accepted: 12/12/2017] [Indexed: 12/19/2022]
Abstract
PURPOSE The adequate perioperative antibiotic prophylaxis in maxillofacial surgery is still under discussion due to the wide range of hard and soft tissue procedures as well as contaminated, semi-contaminated and clean surgical sides. Perioperative antibiosis is an easy applicable tool that can be used to decrease nosocomial morbidity and mortality by reducing the rate of infections. We compared strictly perioperative antibiosis with an extended postoperative prophylactic antibiosis. MATERIALS AND METHODS In this study, 901 consecutive patients, from a tertiary care maxillofacial surgery department were included and distributed into two groups: The first group received peri- and postoperative antibiotic prophylaxis (PP; n = 365) from the day of operation until the fifth day postoperatively. The second group was treated with single shot prophylaxis with intraoperative repetition as needed (SSP; n = 536) only. Furthermore, the patients were grouped according to their main diagnosis and surgical procedure. For comparison, general anamnestic data, cultured bacteria and resistances, number of surgical site infections and duration of hospitalization were compared. RESULTS There were no statistically significant differences in general diseases or extent of surgery between the groups. There was no statistical difference in the surgical site infections between the groups regardless of their diagnosis. There were significant correlations between tracheotomised patients (p < 0.001) as well as patients with a higher BMI (p = 0.009) and the incidence of surgical site infections. Most common cultured bacteria were staphylococci. CONCLUSION Based on the findings of the study, we believe that a perioperative antibiosis delivers a sufficient prophylaxis for patients undergoing maxillofacial surgery procedures.
