Efficacy of introducing a checklist to reduce central venous line associated bloodstream infections in the ICU caring for adult patients.

BACKGROUND: Central line-associated bloodstream infections (CLABSI) are a major source of sepsis in modern intensive care medicine. Some years ago bundle interventions have been introduced to reduce CLABSI. The use of checklists may be an additional tool to improve the effect of these bundles even in highly specialized institutions. In this study we investigate if the introduction of a checklist reduces the frequency of CLABSI. METHODS: During the study period from October 2011 to September 2012, we investigated the effect of implementing a checklist for the placement of central venous lines (CVL). Patients were allocated either to the checklist group or to the control group, roughly in a 1:2 ratio. The frequency of CLABSI was compared between the two groups. RESULTS: During the study period 4416 CVL were inserted; 1518 in the checklist group and 2898 in the control group. The use of the checklist during CVL placement resulted in a lower CLABSI frequency. The incidence in the checklist group was 3.8 per 1000 catheter days as compared to 5.9 per 1000 catheter days in the control group (IRR = 0.57; p = 0.001). The use of the checklist also reduced the frequency of catheter colonisation significantly, 36.3 per 1000 catheter days in the checklist group vs 21.2 per 1000 catheter days in the control group, respectively (IRR = 0.58; p < 0.001). CONCLUSION: The introduction of a checklist to improve the adherence to hygiene standards while placement of central venous lines reduced the frequency of infections significantly.

Characteristics of skin injuries caused by power drill.

Skin injuries caused by power drills have been rarely reported. A case is described of a 51-year-old woman who was found dead on a motorway after committing suicide by jumping from a bridge. The body showed a total of nine circular/oval penetrating injuries of the chest and abdomen with very regular, smooth margins, and particular features due to the presence of "skin islands" inside the lesion and "short radial linear abrasions" around the margins. These injuries were caused by a power drill, which was later found in the woman's apartment. For comparison, experimental tests were carried out with the same drill and different bits on pig skin, whose appearance resembled those found on the body. Especially skin islands were also reproduced in the experimental tests. The presented case shows the possibility of this rare method of suicide (or suicide attempt) and the typical characteristics of such peculiar skin lesions that pose problems of differential diagnosis with other injuries such as gunshot injuries.
