Surgical site infections (SSI) due to Staphylococcus aureus are associated with substantial mortality rates and morbidity. Hence, various strategies are being investigated to prevent them. We explore time trends and risk factors associated with S. aureus SSI to identify high risk patients who might benefit the most from these strategies. ⋯ Future S.aureus SSI prevention measures should focus on patients with risk profiles identified from this and other similar studies.

Risk Adjustment for Determining Surgical Site Infection in Colon Surgery: Are All Models Created Equal?
Colon surgical site infections (SSIs) are being utilized increasingly as a quality measure for hospital reimbursement and public reporting. The Centers for Medicare and Medicaid Services (CMS) now require reporting of colon SSI, which is entered through the U.S. Centers for Disease Control and Prevention's National Healthcare Safety Network (NHSN). However, the CMS's model for determining expected SSIs uses different risk adjustment variables than does NHSN. We hypothesize that CMS's colon SSI model will predict lower expected infection rates than will NHSN. ⋯ The CMS's current risk-adjustment model using age and ASA classification predicts lower rates of expected colon SSIs than does NHSN. This may lead to financial penalties because of the use of limited risk factors. Further efforts at elucidating appropriate risk adjustment measures without unnecessarily burdening hospitals with expensive data collection are necessary.

ReviewPersistent Inflammation, Immunosuppression, and Catabolism: Evolution of Multiple Organ Dysfunction.
Multiple organ dysfunction (MOD) has plagued intensive care units (ICUs) for more than four decades, and its epidemiology has evolved because more patients are surviving previously lethal insults. Over the years, different predominant phenotypes of MOD have been described, all of which have consumed tremendous healthcare resources and have been associated with prolonged ICU stays and prohibitive mortality rates. ⋯ Unfortunately, as our population ages and peri-operative care improves, PICS will become an insurmountable epidemic. We believe PICS is the next horizon in surgical critical care and have developed a program to study the pathogenesis and novel therapies for this vexing problem.

Multicenter StudySurgical Site Infection Rates in Seven Cities in Vietnam: Findings of the International Nosocomial Infection Control Consortium.
Surgical site infections (SSIs) are the most common healthcare-associated infections (HAI) in lower-income countries. This is the first study to report the results of surveillance on SSI stratified by surgical procedure in seven Vietnamese cities. ⋯ Our SSIs rates were significantly higher for 11 of the 26 types of SPs than for the CDC-NHSN. This study advances our knowledge of SSI epidemiology in Vietnam and will allow us to introduce targeted interventions.

A retrospective study was conducted to investigate the validity and the effectiveness of early empiric antibiotic and de-escalation therapy for the treatment of severe sepsis and septic shock patients in the intensive care unit (ICU). ⋯ Empiric antibiotic therapy was acceptable for severe sepsis and septic shock patients treated in the ICU. The appropriate selection of empiric antibiotics was related to a greater rate of de-escalation and better survival. The risk of multi-drug-resistant bacterial infections was not as high as expected, but will need further attention in the future.
