Background: The authors describe a multifaceted cross-infection control program that was implemented to contain an epidemic of multidrug-resistant microorganisms (MRO) (carbapenem resistant Pseudomonas aeruginosa and Acinetobacter baumannii; extended spectrum β-lactamase producing Klebsiella pneumoniae, Escherichia coli, Enterobacter Cloacae, and Proteus mirabilis; and ‎methicillin-resistant Staphylococcus aureus and Candida species). 

Objectives: To assess the effect of a control program on the incidence of cross-infection with MRO.

Methods: Clinical criteria triaged patients into a high-risk wing (HRW) or a low-risk wing (LRW). Strict infection control measures were enforced; violations led to group discussions (not recorded). Frequent cultures were obtained, and use of antibiotics was limited. Each quarter, the incidence of MRO isolation was reported to all staff members. 

Results: Over a 6 year period, 1028 of 3113 patients were placed in the HRW. The incidence of MRO isolation within 48 hours of admission was 8.7% (HRW) vs. 1.91% (LRW) (P < 0.001). Acquired MRO infection density was 30.4 (HRW) vs. 15.6 (LRW) (P < 0.009). After the second year, the incidence of group discussions dropped from once or twice a month to once or twice a year.

Conclusions: These measures contained epidemics. Clinical criteria successfully triaged HRW from LRW patients and reduced cross-infection between the medical center wings. The quarterly reports of culture data were associated with improved staff compliance. MRO epidemic control with limited resources is feasible. 

 

Background: Percutaneous tracheostomy has largely replaced surgical tracheostomy in the intensive care unit setting. Although it seems logical that surgeons continue to do tracheostomies, anesthesiologists and intensive care specialists are familiar with airway control and guide wire techniques and could replace surgeons in the performance of PDT.

Objectives: To assess the safety and effectiveness of bedside PDT[1] in the ICU[2].

Methods: We conducted a retrospective chart review of 207 patients in the ICU who underwent PDT by an intensive care physician.

Results: Subcutaneous emphysema without pneumothorax occurred in one patient. Four patients underwent surgical revision following PDT. Early bleeding (during the first 48 hours following the procedure) was the indication in two patients and late bleeding, on the 10th post-PDT day, in one. In one case PDT was converted to surgical tracheostomy due to inadvertent early decannulation. There was one death directly related to the procedure, due to an unrecognized paratracheal insertion of the tracheostomy tube followed by mechanical ventilation, which led to bilateral pneumothorax, pneumomediastinum and cardio-circulatory collapse. No infectious complications were seen at the stoma site or surrounding tissues.

Conclusions: PDT by intensive care physicians appears to be safe and should be included in the curriculum of intensive care residency.
