ReviewColonization and bloodstream infection with single- versus multi-lumen central venous catheters: a quantitative systematic review.
There is a controversy as to whether the number of lumens in the central venous catheters may impact the incidence of catheter-related bloodstream infection. We performed a systematic search (MEDLINE, PREMEDLINE, Cochrane Library, EMBASE, BIOSIS Previews, CINAHL, HealthSTAR/Ovid healthstar, bibliographies, any language, to April, 2003) for full reports on randomized comparisons of single-lumen and multi-lumen catheters. Trials had to report on dichotomous data of catheter colonization or bloodstream infection. ⋯ For every 20 single-lumen catheters inserted, one bloodstream infection will be avoided that would have occurred had multi-lumen catheters been used. The risk of catheter colonization is not decreased. Although these conclusions are based on limited data, single-lumen catheters should be used whenever feasible.

Clinical TrialA restrictive use of both autologous donation and recombinant human erythropoietin is an efficient policy for primary total hip or knee arthroplasty.
A limitation of preoperative autologous blood donation (PABD) in nonanemics and the use of recombinant human erythropoietin (EPO) in anemics (baseline hematocrit [Hct] < or = 39%) could be an efficient approach of the cost-benefit ratio of transfusion during primary total hip (THA) or knee (TKA) arthroplasties. We evaluated the consequences on transfusion rates and costs of two different applications of a transfusion policy based on personal requirements during primary THA or TKA. This quality assurance observational study compared two prospective successive time periods; each included successive patients treated by the same medical team and standardized care. ⋯ This novel care induced a marked decrease in transfusion rates (respectively, from 41% to 7%, P < 0.0002, in nonanemics; from 58% to 27%, P < 0.003, in anemics; and from 43% to 12%, P < 0.0001, overall), with no change in allogeneic transfusion (10%) and discharge Hct, and a 39% financial savings. This saving effect is a result of the suppression of PABD in nonanemics, who represent 75% of this surgical population. Although erythropoietin is expensive, it can be used with cost savings in selected patients because the overall cost of transfusion is reduced.
