The use of adequate charts for “AHR consumption process” (Poisson charts) showed numerous “positive special causes” during the intervention period. As it has been previously reported, a positive special cause was detected particularly during the 2009 novel H1N1 influenza outbreak [21]. This fact corroborates the validity of our data and clearly illustrates how powerful self-protection is for HCWs [17]. Finally, our data have showed a small but significant decrease in MRSA rate in a low endemic setting through a PEWMA chart (that fits well when very few events are present) despite a significant increase in the use of antibiotics in general and of fluoroquinolones in particular. However, some caution is warranted as to attribute the observed results to the intervention in the absence of a controlled set-up or interrupted time series [56] analysis (which may not be appropriate when there are very few events, as in our case).detecting “non-random” variations (special causes) of the process over time.Future researchFuture multicenter studies are needed in order to corroborate the external validity of our improvement quality project.Supporting InformationText S1 Deciding on the Best control chart (StatisticalProcess Control).

The first confirmed case of novel influenza A (H1N1) in Korea was registered on May 1, 2009 [1], and 225 deaths had been reported by January 1, 2010 [2]. Soon after the first death was documented on August 15, 2009, the SKF-96365 (hydrochloride) manufacturer Korean Health Authority revised the national guidelines so that confirmed tests would no longer be required, and general and prompt treatm.Ties [6].
