Dutra KJ, Lazenby GB, Goje O, Soper DE. Cefazolin as the mainstay for antibiotic prophylaxis in patients with a penicillin allergy in obstetrics and gynecology. Am J Obstet Gynecol 2024:S0002-9378(24)00448-4. [PMID: 38527607 DOI: 10.1016/j.ajog.2024.03.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 02/20/2024] [Accepted: 03/13/2024] [Indexed: 03/27/2024]
Abstract
Cefazolin is the most common antibiotic used for prophylaxis in obstetrics and gynecology. Among those with a penicillin allergy, alternative antibiotics are often chosen for prophylaxis, given fears of cross-reactivity between penicillin and cefazolin. Alternative antibiotics in this setting are associated with adverse sequelae, including surgical site infection, induction of bacterial resistance, higher costs to the healthcare system, and possible Clostridium difficile infection. Given the difference in R1 side chains between penicillin and cefazolin, cefazolin use is safe and should be recommended for patients with a penicillin allergy, including those who experience Immunoglobulin E-mediated reactions such as anaphylaxis. Cefazolin should only be avoided in those who experience a history of a severe, life-threatening delayed hypersensitivity reaction manifested as severe cutaneous adverse reactions (Steven-Johnson Syndrome), hepatitis, nephritis, serum sickness, and hemolytic anemia in response to penicillin administration. In addition, >90% of those with a documented penicillin allergy do not have true allergies on skin testing. Increased referral for penicillin allergy testing should be incorporated into routine obstetric care and preoperative assessment to reduce suboptimal antibiotic prophylaxis use. More education is needed among providers surrounding penicillin allergy assessment and cross-reactivity among penicillins and cephalosporins to optimize antibiotic prophylaxis in obstetrics and gynecology.

Surgical Complications and Hospital Costs in Robot-Assisted Versus Conventional Laparoscopic Hysterectomy With Concurrent Sacrocolpopexy: Analysis of the Nationwide Readmissions Database. Female Pelvic Med Reconstr Surg 2022; 28:e142-e148.

Abstract
OBJECTIVES Despite increasing use of robotic technology for minimally invasive hysterectomy with sacrocolpopexy, evidence supporting the benefits of these costly procedures remains inconclusive. This study aimed to compare differences in perioperative complications, 30-day readmissions, and costs between robot-assisted and conventional laparoscopic hysterectomy with concurrent sacrocolpopexy using a large national database. METHODS Using the 2009-2015 Nationwide Readmissions Database and procedure codes, we identified patients who underwent a robot-assisted or conventional laparoscopic hysterectomy with sacrocolpopexy. We measured in-hospital perioperative complications using diagnosis and procedure codes and measured 30-day readmissions based on patient linkages across hospitalizations. Hospital costs were estimated using charges and cost-to-charge ratios. These outcomes were compared between robot-assisted and conventional laparoscopic procedures using bivariate and multivariable regression analysis. RESULTS Our weighted sample included a total of 7,675 patients. Major perioperative complications occurred in 6.7% of robot-assisted and 11.2% of conventional laparoscopic procedures (unadjusted P < 0.001; adjusted odds ratio, 0.69; 95% confidence interval, 0.51-0.93; P = 0.02). Hospital costs were higher in robot-assisted than in conventional laparoscopic procedures (respective median costs, $16,367 vs $13,898; P < 0.001), with an adjusted cost ratio of 1.24 (95% confidence interval, 1.17-1.31; P < 0.001). The risk of 30-day readmission was similar between robot-assisted and conventional laparoscopic procedures. CONCLUSIONS Nationally representative data suggest that, in laparoscopic hysterectomy with sacrocolpopexy, the robot-assisted approach is associated with a lower risk of perioperative complications, despite higher costs, compared with the conventional one. The risk of 30-day readmission was similar between the robot-assisted and conventional laparoscopic approaches.

Assessment of risk and economic burden of surgical site infection (SSI) posthysterectomy using a U.S. longitudinal database. Surgery 2021; 171:1320-1330. [PMID: 34973811 DOI: 10.1016/j.surg.2021.11.034] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2021] [Revised: 11/17/2021] [Accepted: 11/29/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Surgical site infection posthysterectomy has significant impact on patient morbidity, mortality, and health care costs. This study evaluates incidence, risk factors, and total payer costs of surgical site infection after hysterectomy in commercial, Medicare, and Medicaid populations using a nationwide claims database. METHODS IBM MarketScan databases identified women having hysterectomy between 2014 and 2018. Deep-incisional/organ space (DI/OS) and superficial infections were identified over 6 months postoperatively with risk factors and direct infection-associated payments by insurance type over a 24-month postoperative period. RESULTS Analysis identified 141,869 women; 7.8% Medicaid, 5.8% Medicare, and 3.9% commercially insured women developed deep-incisional/organ space surgical site infection, whereas 3.9% Medicaid, 3.2% Medicare, and 2.1% commercially insured women developed superficial infection within 6 months of index procedure. Deep-incisional/organ space risk factors were open approach (hazard ratio, 1.6; 95% confidence interval, 1.5-1.8) and payer type (Medicaid versus commercial [hazard ratio, 1.4; 95% confidence interval, 1.3-1.5]); superficial risk factors were payer type (Medicaid versus commercial [hazard ratio, 1.4; 95% confidence interval, 1.3-1.6]) and solid tumor without metastasis (hazard ratio, 1.4; 95% confidence interval, 1.3-1.6). Highest payments occurred with Medicare ($44,436, 95% confidence interval: $33,967-$56,422) followed by commercial ($27,140, 95% confidence interval: $25,990-$28,317) and Medicaid patients ($17,265, 95% confidence interval: $15,247-$19,426) for deep-incisional/organ space infection at 24-month posthysterectomy. CONCLUSIONS Real-world cost of managing superficial, deep-incisional/organ space infection after hysterectomy was significantly higher than previously reported. Surgical approach, payer type, and comorbid risk factors contributed to increased risk of infection and economic burden. Medicaid patients experienced the highest risk of infection, followed by Medicare patients. The study suggests adoption of a robust evidence-based surgical care bundle to mitigate risk of surgical site infection and economic burden is warranted.

Abstract
BACKGROUND Antiseptic vaginal preparation is recommended before gynecologic surgery; however, there is a lack of data regarding the effectiveness of different agents. OBJECTIVE To compare rates of postoperative infectious complications and hospital utilization with preoperative vaginal preparation using povidone-iodine or chlorhexidine before hysterectomy. STUDY DESIGN This was a retrospective analysis of patients who underwent hysterectomy for gynecologic indications at 70 hospitals in a statewide surgical collaborative between January 2017 and December 2019. The primary outcome was postoperative infectious complications (including urinary tract infection, surgical site infections involving superficial, deep, or organ space tissues, or cellulitis) within 30 days of surgery. To adjust for confounding, propensity score matching, 1:1 without replacement and with a caliper of.005 was performed to create cohorts that had vaginal preparation with either povidone-iodine or chlorhexidine and did not differ in observable characteristics. We compared the rates of infectious morbidity and hospital utilization (emergency department visits, readmission, reoperation) in the matched cohorts. RESULTS In the statewide collaborative, there were 18,184 patients who received povidone-iodine and 3018 who received chlorhexidine. After propensity score matching of 2935 pairs, the povidone-iodine and chlorhexidine groups did not differ in demographics, comorbidities, choice of preoperative antibiotics, benign vs malignant surgical indication, and surgical approach. Povidone-iodine was associated with a lower rate of infectious morbidity (3.0% vs 4.3%; P=.01), urinary tract infection (1.1% vs 1.7%; P=.03) and emergency department visits (7.9% vs 9.7%; P=.01) than with chlorhexidine. There were nonsignificant trends of lower rates of surgical site infection (2.0% vs 2.7%; P=.07) and reoperation (1.6% vs 2.1%; P=.18). CONCLUSION This propensity score matched analysis provides evidence that povidone-iodine is preferable to chlorhexidine for vaginal preparation before hysterectomy because of lower rates of infectious morbidity and fewer emergency department visits. However, the absolute differences in infectious morbidity rates were approximately 1%, and in the event of an iodine allergy, chlorhexidine appears to be a reasonable alternative.

Abstract
OBJECTIVE To evaluate whether a series of quality improvement interventions to promote safe perioperative use of cephalosporins in penicillin-allergic patients improved use of first-line antibiotics and decreased costs. DESIGN Before-and-after trial following several educational interventions. SETTING Academic medical center. PATIENTS This study included patients undergoing a surgical procedure involving receipt of a perioperative antibiotic other than a penicillin or carbapenem between January 1, 2017, and August 31, 2019. Patients with and without a penicillin allergy label in their electronic medical record were compared with respect to the percentage who received a cephalosporin and average antibiotic cost per patient. METHODS A multidisciplinary team from infectious diseases, allergy, anesthesiology, surgery, and pharmacy surveyed anesthesiology providers about their use of perioperative cephalosporins in penicillin-allergic patients. Using findings from that survey, the team designed a decision-support algorithm for safe utilization and provided 2 educational forums to introduce this algorithm, emphasizing the safety of cefazolin or cefuroxime in penicillin-allergic patients without history of a severe delayed hypersensitivity reaction. RESULTS The percentage of penicillin-allergic patients receiving a perioperative cephalosporin improved from ∼34% to >80% following algorithm implementation and the associated educational interventions. This increase in cephalosporin use was associated with a ∼50% reduction in antibiotic cost per penicillin-allergic patient. No significant adverse reactions were reported. CONCLUSIONS An educational antibiotic stewardship intervention produced a significant change in clinician behavior. A simple intervention can have a significant impact, although further study is needed regarding whether this response is sustained and whether an educational intervention is similarly effective in other healthcare systems.

Abstract
PURPOSE OF REVIEW Surgical site infection (SSI) remains one of the most common postoperative surgical complications. Prevention and appropriate treatment remain paramount. RECENT FINDINGS Evidence-based recommendations include recognition and reduction of preoperative risks including hyperglycemia and smoking, treatment of preexisting infections, skin preparation with chlorhexidine gluconate, proper use of preoperative antibiotics, and implementation of prevention bundles. Consideration should be given to the use of dual antibiotic preoperative treatment with cephazolin and metronidazole for all hysterectomies. SUMMARY Despite advancements, SSI in gynecologic surgery remains a major cause of perioperative morbidity and healthcare cost. Modifiable risk factors should be evaluated and patients optimized to the best extent possible prior to surgery. Preoperative risks include obesity, hyperglycemia, smoking, and untreated preexisting infections. Intraoperative risk-reducing strategies include appropriate perioperative antibiotics, correct topical preparation, maintaining normothermia, and minimizing blood loss. Additionally, early recognition and prompt treatment of SSI remain crucial.

Abstract
Surgical site infections (SSIs) negatively affect patients and health care organizations. We conducted a descriptive, correlational study at two hospitals that provide care to rural patients in one Midwestern state. The study purposes were to describe: types of organisms causing reportable organ/space SSIs that occurred within 30 days of an open or a laparoscopic abdominal surgery (N = 20), and commonalities in patient- and care-related factors to provide baseline information for site-level prevention efforts for quality improvement. We identified Escherichia coli in almost half of the SSI cases (n = 9, 45%). Common patient-related factors included ethnicity, smoking, and dirty or contaminated wounds. Common care-related factors included longer surgery times (> 60 minutes), unplanned surgeries, and procedures that involved the colon or small bowel. Personnel can use site-level data to monitor prevalent types of organisms causing SSIs, enabling an evidence-based, interdisciplinary approach to develop and test methods to enhance prevention.

Abstract
STUDY OBJECTIVE To evaluate whether diabetes diagnosis and level of diabetes control as reflected by higher preoperative glycosylated hemoglobin (HbA1c) levels are associated with increased complication rates after hysterectomy and to identify a threshold of preoperative HbA1c level past which we should consider delaying surgery owing to increased risk of complications. DESIGN Retrospective cohort study. SETTING Hospitals in the Michigan Surgical Quality Collaborative between June 4, 2012, and October 17, 2017. PATIENTS Women with and without a diabetes diagnosis. INTERVENTIONS Hysterectomy. MEASUREMENTS AND MAIN RESULTS Data on demographics, preoperative HbA1c values, surgical approach, composite postoperative complications, readmissions, emergency department visits, and reoperations were abstracted. The risk of a postoperative complication when diabetes was stratified by preoperative HbA1c level was evaluated in a sensitivity analysis, and independent associations were identified in a mixed, multivariate logistic regression model. We identified 41 286 hysterectomies performed at 70 hospitals to be included for analysis. The sensitivity analysis identified 4 groups of risk for postoperative complications: group 1: no diabetes diagnosis and no HbA1c value; group 2: no diabetes diagnosis, with HbA1c levels between 4% and 6.5%; group 3: diabetes diagnosis and no HbA1c value or HbA1c levels <9%; and group 4: diabetes diagnosis with HbA1c levels ≥9%. In the adjusted model, there were significant 32% and 34% increased odds of postoperative complications for groups 2 and 3, respectively, compared with group 1. There were more than 2-fold increased odds of complications for women with diabetes and a preoperative HbA1c level ≥9% (group 4) compared with the women in group 1. Diabetes diagnosis with preoperative HbA1c levels ≥9% had increased odds of complications compared with diabetes diagnosis with preoperative HbA1c levels <9%. Patients with well-controlled diabetes seemed to have increased odds of complications with laparoscopic surgery. CONCLUSION Diabetes diagnosis and measurement of preoperative HbA1c levels provide risk stratification for postoperative complications after hysterectomy, with the highest observed effect among patients with diabetes with a preoperative HbA1c level ≥9%.

Abstract
Background Pelvic hematoma is a common finding following hysterectomy which at times may become infected causing substantial morbidity. The aim of this study was to describe the incidence, clinical manifestation and identify risk factors for infected pelvic hematoma. We also attempted to identify specific bacterial pathogens which may cause this phenomenon. Methods We conducted a retrospective cohort study at a tertiary university teaching hospital. Included were all women who underwent hysterectomy and were diagnosed with a pelvic hematoma following surgery from 2013 to 2018. In an attempt to assess possible risk factors for infected pelvic hematoma women with asymptomatic pelvic hematoma were compared to women with an infected pelvic hematoma. Results During the study period 648 women underwent hysterectomy at our medical center. Pelvic hematoma was diagnosed by imaging in 50 women (7.7%) including 41 women who underwent vaginal hysterectomy and 9 women who underwent abdominal hysterectomy. In 14 (2.2%) cases the hematoma became infected resulting in need for readmission and further treatment. Women who underwent vaginal surgery were more likely to return with infected pelvic hematoma compared to women who underwent open abdominal or laparoscopic surgery (4.5% vs. 1.1%, p < 0.05). In 8 women bacterial growth from hematoma culture was noted. Enterococcus faecalis, was the most abundant pathogen to be isolated in this sub-group. Conclusion Vaginal route of hysterectomy is a risk factor for infected pelvic hematoma following hysterectomy. Most of these infections were caused by anaerobic bacteria which may not be sufficiently covered by current antibiotic prophylactic regimens.

Abstract
This is the first Enhanced Recovery After Surgery (ERAS) guideline dedicated to standardizing and optimizing perioperative care for women undergoing minimally invasive gynecologic surgery. The guideline was rigorously formulated by an American Association of Gynecologic Laparoscopists Task Force of US and Canadian gynecologic surgeons with special interest and experience in adapting ERAS practices for patients requiring minimally invasive gynecologic surgery. It builds on the 2016 ERAS Society recommendations for perioperative care in gynecologic/oncologic surgery by serving as a more comprehensive reference for minimally invasive endoscopic and vaginal surgery for both benign and malignant gynecologic conditions. For example, the section on preoperative optimization provides more specific recommendations derived from the ambulatory surgery and anesthesia literature for the management of anemia, hyperglycemia, and obstructive sleep apnea. Recommendations pertaining to multimodal analgesia account for the recent Food and Drug Administration warnings about respiratory depression from gabapentinoids. The guideline focuses on workflows important to high-value care in minimally invasive surgery, such as same-day discharge, and tackles controversial issues in minimally invasive surgery, such as thromboprophylaxis. In these ways, the guideline supports the American Association of Gynecologic Laparoscopists and our collective mission to elevate the quality and safety of healthcare for women through excellence in clinical practice.

Abstract
OBJECTIVE To identify the variation in estimated blood loss at the time of hysterectomy for benign indications and to analyze how blood loss is associated with measures of resource utilization and complications. METHODS We conducted a retrospective cohort study and analyzed hysterectomy for benign indications at hospitals in the Michigan Surgical Quality Collaborative between January 1, 2013, and May 30, 2015. A sensitivity analysis was performed to identify how estimated blood loss was associated with measures of utilization (transfusion, readmission, reoperation, and length of stay) and postoperative complications. A hierarchical logistic regression model was used to identify patient level factors independently associated with estimated blood loss greater than 400 mL and to calculate a risk- and reliability-adjusted rate for each hospital. RESULTS There were 18,033 hysterectomies for benign indications from 61 hospitals included for analysis. The median estimated blood loss was 100 mL, and the 90th percentile estimated blood loss was 400 mL. A sensitivity analysis demonstrated increased risks of transfusion, readmission, reoperation, length of stay, and major postoperative complications with estimated blood loss greater than 400 mL. The proportion of hysterectomies at hospitals in the collaborative with estimated blood loss greater than 400 mL ranged from 3.5% to 16.9% after risk and reliability adjustments. The risk factors with the highest adjusted odds for estimated blood loss greater than 400 mL included abdominal surgery compared with laparoscopic hysterectomy (adjusted odds ratio [aOR] 2.8, CI 2.3-3.5), surgical time longer than 3 hours (aOR 3.9, CI 3.3-4.5), and specimen weight greater than 250 g compared with less than 100 g (aOR 4.8, CI 3.9-5.8). Adhesive disease, low surgeon volume, being younger than 40 years of age, having a body mass index greater than 35, and the need for a preoperative transfusion were also statistically significantly associated with estimated blood loss greater than 400 mL. CONCLUSION There is fivefold variation in the hospital rate of hysterectomies with an estimated blood loss greater than 400 mL (90th percentile)-a threshold associated with significantly higher rates of health care utilization and complications. Avoidance of abdominal hysterectomy when possible may reduce intraoperative blood loss and associated sequelae.

Preoperative cefazolin rather than clindamycin or metronidazole is associated with lower postpartum infection among women with chorioamnionitis delivering by cesarean delivery. Am J Obstet Gynecol MFM 2019; 2:100074. [PMID: 33345988 DOI: 10.1016/j.ajogmf.2019.100074] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2019] [Revised: 11/13/2019] [Accepted: 11/17/2019] [Indexed: 11/21/2022]
Abstract
BACKGROUND The optimal antibiotic regimen to prevent maternal postpartum infection among high-risk women treated for chorioamnionitis delivering by cesarean delivery remains to be defined. Emerging data suggest that cefazolin decreases the risk of cesarean surgical site infection. OBJECTIVE To investigate whether intrapartum antibiotic therapy with cefazolin versus the current standard clindamycin or metronidazole decreases the risk of postpartum infectious morbidity among women delivering by cesarean delivery who were receiving a base regimen of ampicillin or penicillin with gentamicin for chorioamnionitis. MATERIALS AND METHODS A secondary analysis from the Maternal-Fetal Medicine Units Network (MFMU) Cesarean Registry. We included women who delivered by cesarean delivery with presumptive chorioamnionitis (intrapartum fever >100.4°F and receipt of intrapartum antibiotics). All women received a base regimen of penicillin or ampicillin with gentamicin. We compared antibiotic therapy with cefazolin versus clindamycin or metronidazole. The primary outcome was a composite of postpartum maternal infection, including endometritis and surgical site infection. Multivariable logistic regression was used, adjusting for age, parity, race/ethnicity, insurance, body mass index at delivery, tobacco use, pregestational diabetes, American Society of Anesthesiologists classification, trial of labor prior to cesarean delivery, and postpartum antibiotics. RESULTS Among 1105 women with presumptive chorioamnionitis who delivered by cesarean delivery, 22.0% (n = 244) received cefazolin and 77.9% (n = 861) received clindamycin or metronidazole. Most women were in labor prior to cesarean delivery (93.8%) and received postpartum antibiotics (88.4%). Almost one-tenth (9.5%) were diagnosed with a postpartum infection, most commonly endometritis (80.9%), followed by surgical site infection (20.9%) (not mutually exclusive). Women treated with cefazolin rather than clindamycin or metronidazole had lower odds of postpartum infectious morbidity (adjusted odds ratio, 0.49; 95% confidence interval, 0.26-0.90). This association held when the outcome was restricted to surgical site infection (adjusted odds ratio, 0.11; 95% confidence interval, 0.01-0.92) but not endometritis. Similar results were observed with propensity score analysis. CONCLUSION Among women delivering by cesarean delivery who were treated for chorioamnionitis, additional antibiotic therapy with cefazolin decreased the risk of postpartum infection, primarily surgical site infection, compared to the current standard clindamycin or metronidazole.

Abstract
BACKGROUND Penicillin (PCN) allergy is reported in 10% to 20% of the population; studies show that only 1% to 3% of patients have a true allergy. Most patients reporting a PCN allergy receive second-line antibiotic prophylaxis preoperatively, which raises concerns about antimicrobial efficacy. Studies also suggest that second-line antibiotics may increase the rate of surgical site infection (SSI). In this study we aim to analyze the effect of PCN allergy on antibiotic type prescribed and SSI in our total joint arthroplasty population. METHODS A retrospective review of 4,903 primary total hip and total knee arthroplasty performed from January 2015 to June 2017 in a single institution. A detailed chart review was performed to identify reported reactions and antibiotic prescribed. RESULTS Seven hundred ninety-six patients (16.2%) reported a PCN allergy; the reactions were classified into three tiers. Six hundred fifteen patients (12.5%) reported an IgE-mediated allergy, hypersensitivity, or a possible allergy; 89 (1.8%) reported an adverse effect; and 92 (1.9%) had an unknown reaction. Patients reporting a PCN allergy were less likely to receive cefazolin (94.9 versus 6.9%; P < 0.001) and more likely to receive clindamycin (1.1 versus 80.7%; P < 0.001) or vancomycin (4.0 versus 12.4%; P < 0.001). There was no difference in infection rate by reported PCN allergy (0.6 versus 0.4%; P = 0.473) or antibiotic prescribed (0.5 versus 0.6%; P = 0.4817). CONCLUSION No patient with a PCN allergy and given cefazolin experienced a reaction; based on reported reactions, most patients with a PCN allergy can safely receive first-line antibiotic therapy. In this population, PCN allergy and second-line antibiotic therapy did not influence the rate of SSI.

Abstract
Background: Our study sought to describe the incidence of culture-confirmed postsurgical Staphylococcus aureus infection after elective hysterectomy and evaluate patient characteristics, risk factors, and economic consequences associated with Staphylococcus aureus infection. Methods: This was a retrospective cohort study of patients in the United States (≥18 years old; Kaiser Permanente health plan members) who underwent elective hysterectomy from 2007 to 2013. Hysterectomies were categorized by surgical setting (inpatient vs. outpatient) and procedure (abdominal, laparoscopic, or vaginal). We estimated the cumulative incidence of culture-confirmed Staphylococcus aureus infection (90 days post-surgery) and compared healthcare resource utilization and costs (within 120 days post-surgery) among patients with/without Staphylococcus aureus infection or with other infection. Results: Among 30,960 patients identified, 20,675 underwent inpatient hysterectomy (abdominal: 47.8%; laparoscopic: 24.8%; vaginal: 27.3%), and 10,285 underwent outpatient hysterectomy (laparoscopic: 86.1%; vaginal: 13.9%). The incidence of culture-confirmed Staphylococcus aureus infection was 0.8% and 0.4% for inpatient (abdominal: 1.2%; laparoscopic: 0.5%; vaginal: 0.2%) and outpatient (laparoscopic: 0.5%; vaginal: 0.1%) surgery, respectively. Patients with Staphylococcus aureus infection had more emergency department visits, hospitalizations, and re-operations compared with patients without infection or with non-Staphylococcus aureus infection. Mean total costs for patients with Staphylococcus aureus infection were higher (inpatient: $18,261; outpatient: $4,422) compared with patients without infection (inpatient: $6,171; p < 0.0001; outpatient: $905; p = 0.0023) or non-Staphylococcus aureus infection (inpatient: $11,207; p = 0.0117; outpatient: $3,005; p = 0.2117). Conclusions: Culture-confirmed postsurgical Staphylococcus aureus infection incidence was predominately associated with procedure type rather than surgical setting. Patients with post-surgical Staphylococcus aureus infection had higher health care utilization and costs than those without infection or with other infection types. Additional effective infection control strategies are needed to reduce the morbidity and costs associated with Staphylococcus aureus infection.

J Am Coll Surg 2019; 229:487-496.e2. [PMID: 31377412 DOI: 10.1016/j.jamcollsurg.2019.07.011] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2019] [Revised: 07/17/2019] [Accepted: 07/23/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND Surgical site infections (SSIs) represent a significant preventable source of morbidity, mortality, and cost. Prophylactic antibiotics have been shown to decrease SSI rates, and β-lactam antibiotics are recommended by national guidelines. It is currently unclear whether recommended β-lactam and recommended non-β-lactam antibiotic regimens are equivalent with respect to SSI risk reduction in colectomy patients. STUDY DESIGN We conducted a retrospective cohort study of SSI rates between prophylactic intravenously administered recommended β-lactam and non-β-lactam in colectomy patients (25 CPT codes) collected by the Michigan Surgical Quality Collaborative from January 2013 to February 2018. Surgical site infection rates were compared as a dichotomous variable (no SSI vs SSI). Mixed-effects regression was used to compare the association between receiving a β-lactam or non-β-lactam antibiotic and likelihood of having an SSI. RESULTS Of 9,949 patients, 9,411 (94.6%) received β-lactam antibiotics and 538 (5.4%) received non-β-lactam antibiotics. Overall, there were 622 (6.3%) patients with SSIs. Of the patients receiving β-lactam antibiotics, SSIs developed in 571 (6.1%) compared with 51 (9.5%) patients in the non-β-lactam group. After applying mixed-effects logistic regression, prophylactic treatment with a non-β-lactam regimen was associated with significantly higher odds of surgical site infection (odds ratio 1.65; 95% CI 1.20 to 2.26; p < 0.01). CONCLUSIONS Colectomy patients receiving β-lactam antibiotics had a lower likelihood of SSI compared with those receiving non-β-lactam antibiotics, even when antibiotics were compliant with national recommendations. Our findings suggest that surgeons should prescribe β-lactam antibiotics for prophylaxis whenever possible, reserving alternatives for those rare patients with true allergies or clinical indications for non-β-lactam antibiotic prophylaxis.

Abstract
In the past, best practices for perioperative management have been based as much on dogma as science. The creation of optimized perioperative pathways, known as enhanced recovery after surgery, has been shown to simultaneously improve patient outcomes and reduce cost. In this article, we critically review interventions (and omission of interventions) that should be considered by every surgical team to optimize preanesthesia care. This includes patient education, properly managing existing medical comorbidities, optimizing nutrition, and the use of medications before incision that have been shown to reduce surgical stress, opioid requirements, and postoperative complications. Anesthetic techniques, the use of adjunct medications administered after incision, and postoperative management are beyond the scope of this review. When possible, we have relied on randomized trials, meta-analyses, and systematic reviews to support our recommendations. In some instances, we have drawn from the general and colorectal surgery literature if evidence in gynecologic surgery is limited or of poor quality. In particular, hospital systems should aim to adhere to antibiotic and thromboembolic prophylaxis for 100% of patients, the mantra, "nil by mouth after midnight" should be abandoned in favor of adopting a preoperative diet that maintains euvolemia and energy stores to optimize healing, and bowel preparation should be abandoned for patients undergoing gynecologic surgery for benign indications and minimally invasive gynecologic surgery.

Abstract
Objective To examine the association between perioperative Beta ( β ))-lactam versus non- β -lactam antibiotics and cesarean delivery surgical site infection (SSI). Study Design Retrospective cohort of women undergoing cesarean delivery from January 1 to December 31, 2014. All women undergoing cesarean after 34 weeks with a postpartum visit were included. Prevalence of SSI was compared between women receiving β -lactam versus non- β -lactam antibiotics. Bivariate analyses were performed using Pearson's Chi-square, Fisher's exact, or Wilcoxon's rank-sum tests. Logistic regression models were fit controlling for possible confounders. Results Of the 929 women included, 826 (89%) received β -lactam prophylaxis and 103 (11%) received a non- β -lactam. Among the 893 women who reported a non-type I (low risk) allergy, 819 (92%) received β -lactam prophylaxis. SSI occurred in 7% of women who received β -lactam antibiotics versus 15% of women who received a non- β -lactam ( p = 0.004). β -Lactam prophylaxis was associated with lower odds of SSI compared with non- β -lactam antibiotics (odds ratio [OR] = 0.43; 95% confidence interval [CI] = 0.22-0.83; p = 0.01) after controlling for chorioamnionitis in labor, postlabor cesarean, endometritis, tobacco use, and body mass index (BMI). Conclusion β -Lactam perioperative prophylaxis is associated with lower odds of a cesarean delivery surgical site infection compared with non- β -lactam antibiotics.

Abstract
OBJECTIVE Current practice guidelines recommend cefazolin, cefoxitin, cefotetan, or ampicillin-sulbactam as first-line antibiotic prophylaxis in hysterectomy. We undertook this systematic review and meta-analysis of randomized controlled trials (RCTs) to determine whether cefazolin, with limited antianaerobic spectrum, is as effective in preventing surgical site-infection (SSI) as the other first-choice antimicrobials that have more extensive antianaerobic activity. METHODS We searched PubMed, Scopus, Web of Science, Cochrane Central, and EMBASE for relevant randomized controlled trials (RCT) in any language up to January 23, 2018. We only included trials that measured SSI (our primary outcome) defined as superficial, deep, or organ space. We excluded trials of β-lactams no longer in clinical use. RESULTS In terms of SSI incidence, cefazolin use was not inferior to its comparator in 12 of 13 individual RCTs included in the analysis. The meta-analysis summary estimate showed a significantly higher SSI risk with cefazolin versus cefoxitin or cefotetan (risk ratio, 1.7; 95% CI, 1.04-2.77; P = .03). However, most studies included nonstandardized dosing and duration of antimicrobial prophylaxis, had indeterminate or high risk of bias, did not include patients with gynecological malignancies, and/or were older RCTs not reflective of current clinical practices. CONCLUSION Due to inherent limitations associated with old RCTs with limited relevance to contemporary surgery, an RCT of cefazolin versus regimens with significant antianaerobic spectrum is needed to establish the optimal choice for SSI prevention in hysterectomy.

Abstract
Surgical-site infections (SSIs) represent a well-known cause of patient morbidity as well as added health care costs. In gynecologic surgery, particularly hysterectomy, SSIs are often the result of a number of risk factors that may or may not be modifiable. As both the Centers for Medicaid and Medicare Services and the Joint Commission on the Accreditation of Healthcare Organizations have identified SSIs as a patient safety priority, gynecologic surgeons continue to seek out the most effective interventions for SSI prevention. This review studies the epidemiology and pathophysiology of SSIs in gynecologic surgery and evaluates the current literature regarding possible interventions for SSI prevention, both as individual measures and as bundles. Data from the obstetrical and general surgery literature will be reviewed when gynecological data are either unclear or unavailable. Practitioners and hospitals may use this information as they develop strategies for SSI prevention in their own practice.

Abstract
BACKGROUND Organisms that are isolated from vaginal cuff infections and pelvic abscesses after hysterectomy frequently include anaerobic vaginal flora. Metronidazole has outstanding coverage against nearly all anaerobic species, which is superior to both cefazolin and second-generation cephalosporins. Cefazolin plus metronidazole has been demonstrated to reduce infectious morbidity compared with either cefazolin or second-generation cephalosporins in other clean-contaminated procedures, which include both as colorectal surgery and cesarean delivery. OBJECTIVE The purpose of this study was to evaluate whether the combination of cefazolin plus metronidazole before hysterectomy was more effective in the prevention of surgical site infection than existing recommendations of cefazolin or second-generation cephalosporin. STUDY DESIGN This was a retrospective cohort study of patients in the Michigan Surgical Quality Collaborative from July 2012 through February 2015. The primary outcome was surgical site infection. Patients who were >18 years old and who underwent abdominal, vaginal, laparoscopic, or robotic hysterectomy for benign or malignant indications were included if they received 1 of the following prophylactic antibiotic regimens: cefazolin, second-generation cephalosporin, or cefazolin plus metronidazole. Multivariate logistic regression modeling was performed to evaluate the independent effect of an antibiotic regimen, and propensity score matching was used to validate the findings. RESULTS The study included 18,255 hysterectomies. The overall rate of surgical site infection was 1.8% (n=329). The unadjusted rate of surgical site infection was 1.8% (n=267) for cefazolin, 2.1% (n=49) for second-generation cephalosporin, and 1.4% (n=13) for cefazolin plus metronidazole. After adjustment for differences in patient and operative factors among the antibiotic cohorts, compared with cefazolin plus metronidazole, we found the risk of surgical site infection was significantly higher for patients who received cefazolin (odds ratio, 2.30; 95% confidence interval, 1.06-4.99) or second-generation cephalosporin (odds ratio, 2.31; 95% confidence interval, 1.21-4.41). CONCLUSION In this large cohort, the use of prophylactic cefazolin plus metronidazole resulted in lower surgical site infection rates after hysterectomy compared with cefazolin or second-generation cephalosporin.

Abstract
OBJECTIVE Surgical site infections (SSIs) can lead to substantial morbidity, prolonged hospitalization, increased costs, and death in patients undergoing colorectal procedures. We sought to investigate the effect of using an SSI reduction bundle on the rate of SSIs in gynecologic cancer patients undergoing colon surgery. METHODS We identified all gynecologic cancer patients who underwent colon resection at our institution from 2014 to 2016, during which time a service-wide SSI reduction bundle was introduced. The intervention included preoperative oral antibiotics with optional mechanical bowel preparation, skin preparation with antibacterial solution, and the use of a separate surgical closing tray. SSI rates were assessed within 30days post-surgery. RESULTS Of 233 identified patients, 115 had undergone colon surgery prior to (PRE) and 118 after (POST) the implementation of the intervention. A low anterior resection was the most common colon surgery in both cohorts. The incidence of SSI within 30days of surgery was 43/115 (37%) in the PRE and 14/118 (12%) in the POST cohorts (p≤0.001). Wound dehiscence was noted in 30/115 (26%) and 2/118 (2%) patients, respectively (p≤0.001). In patients whose operation took longer than 360min, 30-day SSI rates were 37% (28/76) and 12% (8/67), respectively (p≤0.001). In patients with an estimated blood loss >500cm3, SSI rates were 44% (27/62) and 15% (10/67), respectively (p≤0.001). CONCLUSIONS The implementation of an SSI reduction bundle was associated with a significant reduction in 30-day SSIs in these patients. The intervention remained effective in patients undergoing longer operations and in those with increased blood loss.

Abstract
Surgical site infections are the most common complication of surgery in the United States. Of surgeries in women of reproductive age, hysterectomy is one of the most frequently performed, second only to cesarean birth. Therefore, prevention of surgical site infections in women undergoing gynecologic surgery is an ideal topic for a patient safety bundle. The primary purpose of this safety bundle is to provide recommendations that can be implemented into any surgical environment in an effort to reduce the incidence of surgical site infection. This bundle was developed by a multidisciplinary team convened by the Council on Patient Safety in Women's Health Care. The bundle is organized into four domains: Readiness, Recognition and Prevention, Response, and Reporting and Systems Learning. In addition to recommendations for practice, each of the domains stresses communication and teamwork between all members of the surgical team. Although the bundle components are designed to be adaptable to work in a variety of clinical settings, standardization within institutions is encouraged.

Abstract
PURPOSE The aim of the study was to identify risk factors associated with postoperative urinary tract infections (UTIs) following hysterectomy-based surgical staging in women with endometrial cancer. METHODS This is a retrospective study utilizing an institutional database (2008-2016) of stage I-IV endometrial cancer cases that underwent hysterectomy-based surgery. UTIs occurring within a 30-day time period after surgery were examined and correlated to patient clinico-pathological demographics. RESULTS UTIs were observed in 44 (6.4%, 95% confidence interval 4.6-8.2) out of 687 cases subsequent to the diagnosis of endometrial cancer. UTI cases were significantly associated with obesity, advanced stage, prolonged operative time, hysterectomy type, pelvic lymphadenectomy, non-β-lactam antibiotics, and intraoperative urinary tract injury (all, p < 0.05). On multivariate analysis, three independent risk factors were identified for UTIs: prolonged operative time [odds ratio (OR) 3.36, 95% CI 1.65-6.87, p = 0.001], modified-radical/radical hysterectomy (OR 5.35, 95% CI 1.56-18.4, p = 0.008), and an absence of perioperative β-lactam antibiotics use (OR 3.50, 95% CI 1.46-8.38, p = 0.005). In a predictive model of UTI, the presence of multiple risk factors was associated with significantly increased risk of UTI: 4.1% for the group with no risk factors, 7.3-12.5% (OR 1.85-3.37) for single risk factor group, and 30.0-30.8% (OR 10.1-10.5) for two risk factor group. CONCLUSION Urinary tract infections are common in women following surgical treatment for women with endometrial cancer with risk factors being a prolonged surgical time, radical hysterectomy, and non-guideline perioperative anti-microbial agent use. Consideration of prophylactic anti-microbial agent use in a high-risk group of postoperative urinary tract infection merits further investigation.

Abstract
BACKGROUND Elective hysterectomy is commonly performed for benign gynaecological conditions. Hysterectomy can be performed abdominally, laparoscopically, or vaginally, with or without laparoscopic assistance. Antibiotic prophylaxis consists of administration of antibiotics to reduce the rate of postoperative infection, which otherwise affects 40%-50% of women after vaginal hysterectomy, and more than 20% after abdominal hysterectomy. No Cochrane review has systematically assessed evidence on this topic. OBJECTIVES To determine the effectiveness and safety of antibiotic prophylaxis in women undergoing elective hysterectomy. SEARCH METHODS We searched electronic databases to November 2016 (including the Cochrane Gynaecology and Fertility Group Specialised Register, the Cochrane Central Register of Studies (CRSO), MEDLINE, Embase, PsycINFO, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL), as well as clinical trials registers, conference abstracts, and reference lists of relevant articles. SELECTION CRITERIA All randomised controlled trials (RCTs) comparing use of antibiotics versus placebo or other antibiotics as prophylaxis in women undergoing elective hysterectomy. DATA COLLECTION AND ANALYSIS We used Cochrane standard methodological procedures. MAIN RESULTS We included in this review 37 RCTs, which performed 20 comparisons of various antibiotics versus placebo and versus one another (6079 women). The quality of the evidence ranged from very low to moderate. The main limitations of study findings were risk of bias due to poor reporting of methods, imprecision due to small samples and low event rates, and inadequate reporting of adverse effects. Any antibiotic versus placebo Vaginal hysterectomyModerate-quality evidence shows that women who received antibiotic prophylaxis had fewer total postoperative infections (risk ratio (RR) 0.28, 95% confidence interval (CI) 0.19 to 0.40; five RCTs, N = 610; I2 = 85%), less urinary tract infection (UTI) (RR 0.58, 95% CI 0.43 to 0.77; eight RCTs, N = 1790; I2 = 44%), fewer pelvic infections (RR 0.28, 95% CI 0.20 to 0.39; 11 RCTs, N = 2010; I2 = 57%), and fewer postoperative fevers (RR 0.43, 95% CI 0.34 to 0.54; nine RCTs, N = 1879; I2 = 48%) than women who did not receive such prophylaxis. This suggests that antibiotic prophylaxis reduces the average risk of postoperative infection from about 34% to 7% to 14%. Whether this treatment has led to differences in rates of other serious infection remains unclear (RR 0.20, 95% CI 0.01 to 4.10; one RCT, N = 146; very low-quality evidence).Data were insufficient for comparison of adverse effects. Abdominal hysterectomyWomen who received antibiotic prophylaxis of any class had fewer total postoperative infections (RR 0.16, 95% CI 0.06 to 0.38; one RCT, N = 345; low-quality evidence), abdominal wound infections (RR 0.64, 95% CI 0.45 to 0.92; 11 RCTs, N = 2434; I2 = 0%; moderate-quality evidence), UTIs (RR 0.39, 95% CI 0.29 to 0.51; 11 RCTs, N = 2547; I2 = 26%; moderate-quality evidence), pelvic infections (RR 0.50, 95% CI 0.35 to 0.71; 11 RCTs, N = 1883; I2 = 11%; moderate-quality evidence), and postoperative fevers (RR 0.60, 95% CI 0.51 to 0.70; 11 RCTs, N = 2581; I2 = 51%; moderate-quality evidence) than women who did not receive prophylaxis, suggesting that antibiotic prophylaxis reduces the average risk of postoperative infection from about 16% to 1% to 6%. Whether this treatment has led to differences in rates of other serious infection remains unclear (RR 0.44, 95% CI 0.12 to 1.69; two RCTs, N = 476; I2 = 29%; very low-quality evidence).It is unclear whether rates of adverse effects differed between groups (RR 1.80, 95% CI 0.62 to 5.18; two RCTs, N = 430; I2 = 0%; very low-quality evidence). Head-to-head comparisons between antibiotics Vaginal hysterectomyWe identified four comparisons: cephalosporin versus penicillin (two RCTs, N = 470), cephalosporin versus tetracycline (one RCT, N = 51), antiprotozoal versus lincosamide (one RCT, N = 80), and cephalosporin versus antiprotozoal (one RCT, N = 78). Data show no evidence of differences between groups for any of the primary outcomes, except that fewer cases of total postoperative infection and postoperative fever were reported in women who received cephalosporin than in those who received antiprotozoal.Only one comparison (cephalosporin vs penicillin; two RCTs, N = 451) yielded data on adverse effects and showed no differences between groups. Abdominal hysterectomyWe identified only one comparison: cephalosporin versus penicillin (N = 220). Data show no evidence of differences between groups for any of the primary outcomes. Adverse effects were not reported. Combined antibiotics versus single antibiotics Vaginal hysterectomyWe identified three comparisons: cephalosporin plus antiprotozoal versus cephalosporin (one RCT, N = 78), cephalosporin plus antiprotozoal versus antiprotozoal (one RCT, N = 78), and penicillin plus antiprotozoal versus penicillin (one RCT, N = 230). Data were unavailable for most outcomes, including adverse effects. We found no evidence of differences between groups, except that fewer women receiving cephalosporin with antiprotozoal received a diagnosis of total postoperative infection, UTI, or postoperative fever compared with women receiving antiprotozoal. Abdominal hysterectomyWe identified one comparison (penicillin plus antiprotozoal vs penicillin only; one RCT, N = 230). Whether differences between groups occurred was unclear. Adverse effects were not reported. Comparison of cephalosporins in different regimensSingle small trials addressed dose comparisons and provided no data for most outcomes, including adverse effects. Whether differences between groups occurred was unclear. No trials compared route of administration.The quality of evidence for all head-to-head and dose comparisons was very low owing to very serious imprecision and serious risk of bias related to poor reporting of methods. AUTHORS' CONCLUSIONS Antibiotic prophylaxis appears to be effective in preventing postoperative infection in women undergoing elective vaginal or abdominal hysterectomy, regardless of the dose regimen. However, evidence is insufficient to show whether use of prophylactic antibiotics influences rates of adverse effects. Similarly, evidence is insufficient to show which (if any) individual antibiotic, dose regimen, or route of administration is safest and most effective. The most recent studies included in this review were 14 years old at the time of our search. Thus findings from included studies may not reflect current practice in perioperative and postoperative care and may not show locoregional antimicrobial resistance patterns.

Am J Obstet Gynecol 2017; 216:502.e1-502.e11.

Abstract
BACKGROUND Healthcare teams that frequently follow a bundle of evidence-based processes provide care with lower rates of morbidity. Few process bundles to improve surgical outcomes in hysterectomy have been identified. OBJECTIVE The purpose of this study was to investigate whether a bundle of 4 perioperative care processes is associated with fewer postoperative complications and readmissions for hysterectomies in the Michigan Surgical Quality Collaborative. STUDY DESIGN A bundle of perioperative care process goals was developed retrospectively with 30-day peri- and postoperative outcome data from the Hysterectomy Initiative in Michigan Surgical Quality Collaborative. All benign hysterectomies that had been performed between January 2013 and January 2015 were included. Based on evidence of lower complication rates after benign hysterectomy, the following processes were considered to be the "bundle": use of guideline-appropriate preoperative antibiotics, a minimally invasive surgical approach, operative duration <120 minutes, and avoidance of intraoperative hemostatic agent use. Each process was considered present or absent, and the number of processes was summed for a bundle score that ranged from 0-4. Cases with a score of zero were excluded. Outcomes measured were rates of complications (any and major) and hospital readmissions, all within 30 days of surgery. Postoperative events that were considered a "major complication" included acute renal failure, cardiac arrest that required cardiopulmonary resuscitation, central line infection, cerebral vascular accident, death, deep vein thrombosis, intestinal obstruction, myocardial infarction, pelvic abscess, pulmonary embolism, rectovaginal fistula, sepsis, surgical site infection (deep and organ-space), unplanned intubation, ureteral obstruction, and ureterovaginal and vesicovaginal fistula. The outcome "any complication" included all those events already described in addition to blood transfusion within 72 hours of surgery, urinary tract infection, and superficial surgical site infection. Outcomes were adjusted for patient demographics, surgical factors, and hospital-level clustering effects. RESULTS There were 16,286 benign hysterectomies available for analysis. Among all hysterectomies that were reviewed, 33.6% met criteria for all bundle processes; however, there was wide variation in the rate among the 56 hospitals in the study sample with 9.1% of cases at the lowest quartile and 60.4% at the highest quartile of hospitals that met criteria for all bundle processes. Overall, the rate of any complication was 6.8% and of any major complication was 2.3%. The rate of hospital readmissions was 3.6%. After adjustment for confounders, in cases in which all bundle criterion were met compared with cases in which all bundle criterion were not met, the rate of any complications increased from 4.3-7.8% (P<.001); major complications increased from 1.7-2.6% (P<.001), and readmissions increased from 2.6-4.1% (P<.001). After adjustment for confounders, hospitals with greater rates of meeting all 4 criteria were associated significantly with lower hospital-level rates of postoperative complications (P<.001) and readmissions (P<.001). CONCLUSIONS This multiinstitutional evaluation reveals that reduced morbidity and readmission are associated with rates of bundle compliance. The proposed bundle is a surgical goal, which is not possible in every case, and there is significant variation in the proportion of cases meeting all 4 bundle processes in Michigan hospitals. Implementation of evidence-based process bundles at a healthcare system level are worthy of prospective study to determine whether improvements in patient outcomes are possible.

Abstract
BACKGROUND Preoperative antibiotic prophylaxis and surgical technological advances have greatly reduced, but not totally eliminated surgical site infection (SSI) posthysterectomy. We aimed to identify risk factors for SSI posthysterectomy among women with a high prevalence of gynecologic malignancies, in a tertiary care setting where compliance with the Joint Commission's Surgical Care Improvement Project core measures is excellent. METHODS The study was a matched case-control, 2 controls per case, matched on date of surgery. Study time was January 2, 2012-December 31, 2015. Procedures included abdominal and vaginal hysterectomies (open, laparoscopic, and robotic). SSI (superficial incisional or deep/organ/space) was defined as within 30 days postoperatively, per Centers for Disease Control and Prevention criteria. Statistical analysis included bivariate analysis and conditional logistic regression controlling for demographic and clinical variables, both patient-related and surgery-related, including detailed prophylactic antibiotic exposure. RESULTS Of the total 1,531 hysterectomies performed, we identified 52 SSIs (3%), with 60% being deep incisional or organ/space infections. All case patients received appropriate preoperative antibiotics (timing, choice, and weight-based dosing). Bivariate analysis showed that higher median weight, higher median Charlson comorbidity index, immune suppressed state, American Society of Anesthesiologists score ≥ 3, prior surgery within 60 days, clindamycin/gentamicin prophylaxis, surgery involving the omentum or gastrointestinal tract, longer surgery duration, ≥4 surgeons present in the operating room, higher median blood loss, ≥7 catheters or invasive devices in the operating room, and higher median length of hospital stay increased SSI risk (P < .05 for all). Cefazolin preoperative prophylaxis, robot-assisted surgery, and laparoscopic surgery were protective (P < .05 for all). Duration of surgery was the only independent risk factor for SSI identified on multivariate analysis (odds ratio, 3.45; 95% confidence interval, 1.21-9.76; P = .02). CONCLUSIONS In our population of women with multimorbidity and hysterectomies largely due to underlying gynecologic malignancies, duration of surgery, presumed a marker of surgical complexity, is a significant SSI risk factor. The choice of preoperative antibiotic did not alter SSI risk in our study.
