Surgical site infections and cellulitis after abdominal hysterectomy

Reducing abdominal hysterectomy surgical site infections: A multidisciplinary quality initiative

BACKGROUND

To investigate abdominal hysterectomy surgical site infection (SSI) rates before and after implementation of an SSI care bundle.

METHODS

An SSI bundle for abdominal hysterectomies was introduced in our hospital in April 2014 to reduce the SSI rate. The practices were divided into bundle elements around preoperative, intraoperative, and postoperative care. We conducted a retrospective cohort study around implementation of the SSI care bundle. Women were included if they underwent abdominal hysterectomy between 2012 and 2015. They were then divided into 2 study groups: prebundle and postbundle. The primary study outcome was SSI rate. The superficial SSI rate was the secondary outcome.

RESULTS

The overall SSI rate was 6.18% in the prebundle group, with a median monthly SSI rate of 7.03%. After bundle implementation, the overall SSI rate declined to 2.51% (P = .02). The reduction remained significant after multivariate analysis (adjusted odds ratio 0.38; 95% confidence interval 0.15-0.88; P = .03) indicating a 62% reduction in SSI postbundle as compared to prebundle.When comparing rates based on infection classification, superficial SSIs declined significantly from 3.73% in the prebundle group to 0.90% in the postbundle group (P = 0.02). Patient demographics and pre-existing medical conditions were similar pre- and postbundle. Compliance with bundle elements was high.

CONCLUSIONS

A significant reduction in SSI rate in abdominal hysterectomies was seen following implementation of an infection prevention bundle.

Culture-Confirmed Staphylococcus aureus Infection after Elective Hysterectomy: Burden of Disease and Risk Factors

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.

Peri- and postoperative management and outcomes of morbidly obese patients (BMI > 40 kg/m2) with gynaecological disease

INTRODUCTION

For the last two decades, obesity rates have been increasing in both developed and developing countries, with the number of obese women roughly doubling during this period (Stevens et al. in Popul Health Metr 10(1):33, 2012). Obesity represents one of the biggest epidemics of the 21st century. The aim of this retrospective study is to characterise the outcomes of gynaecologic surgeries in cases of extremely obese women with a body mass index (BMI) over 40 kg/m2.

METHODS

This study is a retrospective case control study in a single-centre setting. Our clinical database was searched for gynaecological operations performed on morbidly obese patients (BMI > 40 kg/m2) between 2009 and 2014 in the Department of Gynaecology and Obstetrics at Hannover Medical School. We matched these results with random patients of normal body weight who had similar surgical procedures and diseases.

RESULTS

We included 97 obese patients in our case group and 99 patients in the control group. We found an association between a strongly elevated BMI and peri- and postoperative morbidity. Both intraoperative and postoperative complications are significantly increased in morbid obesity with a BMI over > 40 kg/m2. We observed intraoperative complications in 55.6% and postoperative complications in 50.5% of patients with extreme obesity. In contrast, the complication rate in the control group with a normal BMI was 11% intraoperatively (p = 0.0001) and 3% postoperatively (p = 0.0001). The data showed that perioperative and postoperative morbidity could be reduced by laparoscopic surgery in many cases, with a significant lower rate of difficulties with closing the wound, a significant shorter duration of surgery and a significant lower rate of infections combined with a significant lower reoperation rate and shorter hospital stay. In gynaecological-oncological diseases, we could demonstrate a reduced radicality during the operative procedure due to extreme obesity.

DISCUSSION

Dealing with the growing number of obese patients is essential, because the problems emerging from obesity are manifold for the treating hospitals as well as the general health system. For this high-risk patient group, it is indispensable to obtain a thorough overview of the patient's overall situation preoperatively to ensure good perioperative care and complications management.

Consensus Bundle on Prevention of Surgical Site Infections After Major Gynecologic Surgery

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.

Risk Factors for Surgical Site Infections Following Adult Spine Operations

OBJECTIVE

To identify risk factors for surgical site infections (SSIs) after spine operations.

DESIGN

Case-control study of SSIs among patients undergoing spine operations.

SETTING

An academic health center.

PATIENTS

We studied patients undergoing spinal fusions or laminectomies at the University of Iowa Hospitals and Clinics from January 1, 2007, through June 30, 2009. We included patients who acquired SSIs meeting the National Healthcare Safety Network definition. We randomly selected controls among patients who had spine operations during the study period and did not meet the SSI definition.

RESULTS

In total, 54 patients acquired SSIs after 2,309 spine operations (2.3 per 100 procedures). SSIs were identified a median of 20 days after spinal fusions and 17 days after laminectomies; 90.7% were identified after discharge and 72.2% were deep incisional or organ-space infections. Staphylococcus aureus caused 53.7% of SSIs. Of patients with SSIs, 64.9% (fusion) and 70.6% (laminectomy) were readmitted and 59.5% (fusion) and 64.7% (laminectomy) underwent reoperation. By multivariable analysis, increased body mass index, Surgical Department A, fusion of 4–8 vertebrae, and operation at a thoracic or lumbar/sacral level were significant risk factors for SSIs after spinal fusions. Lack of private insurance and hypertension were significant risk factors for SSIs after laminectomies. Surgeons from Department A were more likely to use nafcillin or vancomycin for perioperative prophylaxis and to do more multilevel fusions than surgeons from Department B.

CONCLUSIONS

SSIs after spine operations significantly increase utilization of healthcare resources. Possible remediable risk factors include obesity, hypertension, and perioperative antimicrobial prophylaxis.

Hysterectomy for benign disease: clinical practice guidelines from the French College of Obstetrics and Gynecology

OBJECTIVE

The objective of the study was to draw up French College of Obstetrics and Gynecology (CNGOF) clinical practice guidelines based on the best available evidence concerning hysterectomy for benign disease.

METHODS

Each recommendation for practice was allocated a grade, which depends on the level of evidence (clinical practice guidelines).

RESULTS

Hysterectomy should be performed by a high-volume surgeon (>10 hysterectomy procedures per year) (gradeC). Stimulant laxatives taken as a rectal enema are not recommended prior to hysterectomy (gradeC). It is recommended to carry out vaginal disinfection using povidone-iodine solution prior to hysterectomy (grade B). Antibiotic prophylaxis is recommended during hysterectomy, regardless of the surgical approach (grade B). The vaginal or laparoscopic approach is recommended for hysterectomy for benign disease (grade B), even if the uterus is large and/or the patient is obese (gradeC). The choice between these two surgical approaches depends on other parameters, such as the surgeon's experience, the mode of anesthesia, and organizational constraints (duration of surgery and medical economic factors). Vaginal hysterectomy is not contraindicated in nulliparous women (gradeC) or in women with previous cesarean section (gradeC). No specific hemostatic technique is recommended with a view to avoiding urinary tract injury (gradeC). In the absence of ovarian disease and a personal or family history of breast/ovarian carcinoma, the ovaries should be preserved in pre-menopausal women (grade B). Subtotal hysterectomy is not recommended with a view to reducing the risk of peri- or postoperative complications (grade B).

CONCLUSION

The application of these recommendations should minimize risks associated with hysterectomy.

[Urinary, infectious and digestive adverse events related to benign hysterectomy and the associated surgery on the Fallopian tube: Guidelines]

OBJECTIVES

To provide clinical practice guidelines from the French College of Obstetrics and Gynecology (CNGOF) based on the best evidence available, concerning the urinary, infectious and digestive adverse events related to benign hysterectomy and the associated surgery including opportunistic salpingectomy and adnexectomy.

MATERIAL AND METHOD

Review of literature using following keywords: benign hysterectomy; urinary injury; bladder injury; ureteral injury; vesicovaginal fistula; infection; bowel injury; salpingectomy.

RESULTS

Urinary catheter should be removed before 24h following uncomplicated hysterectomy (grade B). In case of urinary catheter during hysterectomy, immediate postoperative removal is possible (grade C). No hemostasis technics can be recommended to avoid urinary injury (grade C). There is not any evidence to recommend to perform a window in the broad ligament or an ureterolysis, to put ureteral stent or a uterine manipulator in order to avoid ureteral injury. An antibiotic prophylaxis by a cephalosporin is always recommended (grade B). Mechanical bowel preparation before hysterectomy is not recommended (grade B). If there is no ovarian cyst/disease and no familial or personal history of ovarian/breast cancer, ovarian conservation is recommended in premenopausal women (grade B). In postmenopausal women, informed consent and surgical approach should be taken in account to perform a salpingo-oophorectomy. Since the association salpingectomy and hysterectomy is not assessed in the prevention of ovarian cancer, systematic bilateral salpingectomy is not recommended (expert consensus).

CONCLUSIONS

Practical application of these guidelines should decrease the prevalence of visceral complications associated with benign hysterectomy.
