Highlights: 

  • The risk of infection after spine surgery has increased due to aging of society.
  • An infection control team (ICT) manages infected cases at our hospital.
  • The ICT guided use of antibiotics in 30 cases and investigated infection in 10.
  • The bacteria detection rate was 88% (35/40 patients) in cases treated by the ICT.
  • Early assistance from the ICT is a key to preventing onset of MRSA infection.

Barriers, perceptions, and adherence: Hand hygiene in the operating room and endoscopy suite

Pederson, L. et al. American Journal of Infection Control. Published online: 8 February 2017

11576-2

Highlights: 

  • Barriers and perceptions of nonsurgical scrubbed hand hygiene were examined.
  • Hand hygiene role modeling by health care workers is poor.
  • Self-awareness of hand hygiene practices is inadequate.

Azithromycin Prophylaxis for Cesarean Delivery

Rothaus, C. The New England Journal of Medicine. Published online: September 29th 2016

Cesarean delivery is the most common major surgical procedure and is associated with a rate of surgical-site infection (including endometritis and wound infection) that is 5 to 10 times the rate for vaginal delivery. Tita et al. assessed whether the addition of azithromycin to standard antibiotic prophylaxis before skin incision would reduce the incidence of infection after cesarean section among women who were undergoing nonelective cesarean delivery during labor or after membrane rupture. In this new Original Article involving women who received standard antibiotic prophylaxis for nonelective cesarean section, the risk of infection after surgery was lower with the addition of azithromycin than with placebo.

Clinical Pearl

• How does pregnancy-associated infection rank as a cause of maternal death in the United States?

Globally, pregnancy-associated infection is a major cause of maternal death and is the fourth most common cause in the United States.

Clinical Pearl

• How often do postoperative infections occur after nonelective cesarean delivery?

Despite routine use of antibiotic prophylaxis (commonly, a cephalosporin given before skin incision), infection after cesarean section remains an important concern, particularly among women who undergo nonelective procedures (i.e., unscheduled cesarean section during labor, after membrane rupture, or for maternal or fetal emergencies). As many as 60 to 70% of all cesarean deliveries are nonelective; postoperative infections occur in up to 12% of women undergoing nonelective cesarean delivery with standard preincision prophylaxis.#

Cardiac surgery, nosocomial infection, and the built environment

Sommerstein, R. et al.Journal of Hospital Infection. Published online: 10 May 2016

Heater‒cooler units (HCUs) have received considerable attention from an infection prevention viewpoint in the last two years, as their water reservoir has been linked to healthcare-associated outbreaks. Ten cases of Mycobacterium chimaera infection associated with contaminated HCUs have been described in the literature and the suspected transmission pathway by air was recently substantiated.2,3 Götting et al. now report on the difficulties of physically separating the HCU in order to divert contaminated HCU exhaust air from the surgical field and how they relied on non-fermenters as surrogate micro-organism ‒ despite their unknown significance.

Surgical site infections surveillance

Public Health England has published Surgical site infections in NHS hospitals in England 2014/15. This annual report covers surgical site infection (SSI) data collected by NHS hospitals and independent sector NHS treatment centres.  Data includes information on the number of operations performed, data quality, benchmarks, trends and risk factors. SSIs are also recorded by surgical category for each NHS Trusts in England.

Significant decrease in the incidence of orthopedic MRSA SSIs

  • A prevention bundle was implemented for orthopedic MRSA SSIs.
  • The bundle reinforced contact precaution and AMP stewardship.
  • The MRSA SSI rate correlated negatively with cefazolin AUD.
  • Prolonged AMP may increase the risk of MRSA SSI.
  • The bundle was associated with the decrease in the incidence of MRSA SSIs.

Model for Improvement reduced surgical site infections

An improvement collaborative implemented a care bundle to reduce surgical site infections amongst children. Over a two year period they used the Model for Improvement to develop and implement change. Organisations were encouraged to adopt all or part of the bundle. Support was provided through webinars, discussion boards, targeted messages to leaders and in-person training. Within six months, 97% of organisations were using the bundle reliably. There was a 21% reduction in surgical site infection rates, from an average of 2.5 per 100 procedures to 1.8 per 100 procedures. The reduction was sustained over the 15 month follow-up period.
