Surgical site infection (SSI) after colorectal procedures represents a measurable quality indicator of a healthcare system. There is an increasing interest in comparing SSI rates between different hospitals and countries: however, the variability of the data regarding the incidence of SSI makes this comparison difficult. For the purposes of evaluation, data collection must be standardized and must include reliable post-discharge surveillance (PDS). ⋯ SSI rates in elective colorectal procedures at VINCat hospitals were inside the higher range of those reported by other national programmes. PDS SSI increased the overall rate of SSI, had a significant clinical impact, and accounted for almost a quarter of SSI. Younger age and laparoscopic procedures were the most relevant risk factors. Standardized multimodal PDS should be implemented for hospitals performing surveillance of colorectal surgery.

Previous studies have suggested that the final outcome of a patient with nosocomial pneumonia (NP) may depend on the patient's illness severity upon admission to the intensive care unit (ICU). ⋯ Developing NP while admitted to the ICU was independently associated with increased mortality. However, the strength of the association decreased as the severity of patient illness upon admission to the ICU increased, not influencing death of patients with severe APACHE II values.

Aspiration of subglottic secretions (ASS) is recommended in patients requiring mechanical ventilation for ≥48h. We assessed the impact of the introduction of ASS routinely in all patients after major heart surgery in an ecological study comparing ventilator-acquired pneumonia (VAP) incidence, days of mechanical ventilation, and cost of antimicrobial agents before and after the implementation of ASS. Before and after the intervention the results (per 1000 days) were: VAP incidence, 23.92 vs 16.46 (P = 0.04); cost of antimicrobials, €71,384 vs €63,446 (P = 0.002); and days of mechanical ventilation, 507.5 vs 377.5 (P = 0.009). From the moment of induction of anaesthesia all patients undergoing major heart surgery should routinely receive ASS.

Handshaking is a known vector for bacterial transmission between individuals. Handwashing has become a major initiative throughout healthcare systems to reduce transmission rates, but as many as 80% of individuals retain some disease-causing bacteria after washing. The fist bump is an alternative to the handshake that has become popular. We have determined that implementing the fist bump in the healthcare setting may further reduce bacterial transmission between healthcare providers by reducing contact time and total surface area exposed when compared with the standard handshake.

Arterial catheter-related bloodstream infection: incidence, pathogenesis, risk factors and prevention.
Arterial catheters are essential in critical care for haemodynamic and blood gas monitoring. The risk of infection remains ill defined. ⋯ In patients in intensive care with cryptogenic sepsis or bacteraemia, arterial catheter-related BSI must also be suspected and excluded. The most common route of infection is extraluminal; as such, novel technologies shown to prevent bloodstream infection with CVCs, such as chlorhexidine for cutaneous antisepsis and chlorhexidine-impregnated dressings, may also be of benefit with arterial catheters.
