“…Since 2001, QCC was introduced to medical institutions in China in order to improve the quality of medical services by strengthening medical workers' awareness for discovering and solving medical problems, it is widely used in many aspects of improving medical quality. For example to reduce blood culture contamination rates for department of clinical laboratory (12), improve the intraocular lens power calculation for ophthalmology department (13), improve the hand hygiene compliance (14), reduce the incidence of catheter-associated urinary tract infection for department of nosocomial infection control (15), and so on. However, to our knowledge, no studies have been reported on QCC reducing carbapenem resistance.…”

“…The definition of contamination varied widely amongst the studies included in this review. Nine (15.8%) (26,31,40,43,46,51,63,69,80) studies did not define contamination at all. The majority (34,59.6%) of studies used species-based criteria for the definition of contamination with provisions that a contaminant could be considered a true pathogen if it was found in multiple cultures (6, 13, 20, 22, 24, 25, 28-30, 33, 34, 36-38, 44, 45, 47, 48, 50, 55-59, 61, 65-67, 70, 74-76, 78, 79).…”

Background: Blood culture contamination is a significant problem in acute care settings. Contamination of a blood sample with pathogens not present in the patient's blood leads to increases in length of stay, overuse of antimicrobials, and increases in healthcare cost. Several interventions have been reported in different settings within the literature to decrease the contamination. However, their overall effectiveness is currently unknown. Objective: This systematic review aimed to identify interventions to reduce contamination from peripherally collected blood cultures and to evaluate the effectiveness of these interventions. Design: Systematic review and meta analysis Methods: In March 2019 we performed a systematic search of English language literature from academic databases, registers of clinical trials and grey literature for interventions aimed at reducing blood culture contamination in adult acute care settings. Studies meeting inclusion criteria were reviewed and data were extracted by two independent reviewers. Results: A total of 6,302 articles were retrieved from searches. After removal of duplicates and screening against inclusion criteria 57 studies were included. The majority of the 57 studies had a medium to high risk of bias. These studies identified eight specific interventions (collection packs, dedicated collection teams, education, staff feedback, intervention bundle, sterile procedure, Initial Specimen Diversion Devices, or change of asepsis solution) used in acute care. Thirty-four studies were included in the meta analysis. There was a wide variation in the definition of contamination which precluded many studies from being included in the meta analysis. Dedicated collection teams (RR 0.40, 95%CI 0.21, 0.76, I2 87%, p<0.001) and initial specimen diversion devices (RR 0.43, 95%CI0.31, 0.58, I2 84%, p<0.001) were the most successful at reducing blood culture contamination. Heterogeneity was high across all studies and interventions. Conclusions: The use of dedicated collection teams or initial specimen diversion devices showed the most significant reduction in blood culture contamination; however, other interventions such as intervention bundles, education or feedback, may have benefits in terms of ease of implementation, and have still been shown to lower blood culture contamination.

“…In the activities of the QCC, the x 2 test or t test are often used to evaluate the effect of interventions, 11 which are not rigorous enough in some situations, for example, the data may contain a secular trend before the interventions, therefore exaggerating the effect of interventions. However, interrupted time series analysis (ITSA) can balance the trends of the data before the interventions and examine the real impact of countermeasures.…”

Background: To report a quality control circle (QCC) activity on the theme of reducing the incidence of catheter-associated urinary tract infection (CAUTI), and used an interrupted time series analysis to evaluate the impact of the QCC. Methods: In a general tertiary hospital in Shenzhen, China, we carried out a QCC activity with the theme of reducing CAUTI from April 2017 to December 2017. Before the QCC, we carried out the routine measures; during the QCC, we implemented usual measures and the countermeasures of QCC, and after the QCC, we performed the routine measures and adhered to the core measures of QCC. The interrupted time series analysis method was used to analyze the changes in the CAUTI incidence during the 3 stages. Results: Before, during, and after the QCC activities, the catheter use ratios and mean indwelling time both had a downward trend; meanwhile, the compliance rate of CAUTI prevention measures showed an upward trend. After the interventions, the CAUTI incidence decreased by 1.317% immediately, then gradually decreased by 0.510% per month. After the completion of QCC, the CAUTI incidence increased by 0.266% immediately and increased by 0.070% over time, but the difference was not statistically significant. Conclusions: The CAUTI incidence is reduced through QCC, providing a useful reference for the prevention of CAUTI and the development of medical quality improvement activities.
