OBJECTIVE To analyze the monitoring performance and testing efficacy and reliability of standardized disposable B-D test pack and standard linen test pack,and summarize the corrective actions based on failure analyses for future reference.METHODS The two different test packs were employed to evaluate the vacuum performance of dynamic air removal sterilizer.RESULTS We enrolled 400 standardized disposable B-D test packs and standard linen test packs respectively.The disposable pack failed 4 cases with the success ratio 99%,while the linen pack failed 30 cases with the success ratio 92.5%.CONCLUSIONS The poor conformity of hand-made linen test pack,variation of steam pressure,sterilizer failure,and unprofessionalism of sterilizer operator contribute as main failure causes in B-D test.Standardized disposable B-D test pack can decrease subjective factors significantly,and the test results are more reliable and standardized.

【Objective】 To evaluate the influence of establishing " blood station-hospital" information management system, based on the concept of Internet, on blood supply and use. 【Methods】 Blood information management system was established in our blood station, and connected to 21 secondary and above hospitals with blood storage function in Maoming to achieve interconnection and timely observation and recording of blood collection, supply and use. The working intensity, blood appointment, incidence of adverse reactions of clinical blood transfusion and satisfaction rate of clinical blood consumption before (April 2017 to March 2018) and after (April 2018 to March 2019) the application of the blood station-hospital information system were compared. 【Results】 In the same period before and after the implementation of blood station-hospital information system, the blood volume (U) collected was 78 249 vs 87 044.5, and the total blood supplied (U) was 225 276.5 vs 249 303, with growth rates at 11.24% and 10.67%, respectively; The average daily working intensity (s) of blood supply staff was 68.68±4.13 vs 41.71±3.76 (P<0.01), and average daily area (m²) was 9.82±3.51 vs 3.31±3.49 (P<0.05). The appointment time of clinical blood by telephone (s) was 110.34±6.79 vs 56.38±4.18 (P< 0.01), by network was 28.55±2.27 vs 13.48±2.76 (P<0.01); The incidence of transfusion adverse reactions was 0.035% (11/31 250) vs 0.012% (5/42 314) P<0.05); The satisfaction rates of clinical blood consumption were 85.71% (18/21) vs 100% (21/21) (P<0.01). 【Conclusion】 The implementation of blood station-hospital information system improved the efficiency of blood collection and supply in blood stations, and reduced the work intensity of blood supply staff. It is beneficial to reduce the incidence of adverse reactions of clinical blood transfusion and improve the satisfaction rate of blood consumption.
