ABSTRACT
Objective To compare and study the two kinds of quality control methodologies related to intelligent quality management system ( iQM) and traditional quality control , and the quality control performance of iQM equivalent to traditional quality control were evaluated , ensuring the accuracy of the results of blood gas testing.Methods Beijing Chaoyang Hospital of Capital Medical University , Beijing Tiantan Hospital of Capital Medical University , Shanghai Longhua Hospital of Shanghai University of Chinese Medicine, and Sichuan Provincial People′s Hospital, these 4 medical institutions were selected to implement this study.During the period from June 2016 to December 2016, in the routine detection of total 3 712 specimen, the iQM and traditional quality control modes were used simultaneously to calculate the mean values of all blood gas parameters quality controls , SD, CV (%) and Sigma values, to evaluate the quality control performance and difference of the two quality control modes .Results During the process of testing blood gas samples from 3 712 specimen in 4 hospitals, iQM process control solution ( PCS) A, B, C ran 1 089, 7 678 and 154 quality control samples respectively , and 732 external quality control samples were run by traditional quality control mode .Considering the most sensitive parameters of blood gas testing pO 2, iQM PCS A, B, C′s Sigma value are higher than 8, however, the traditional quality control′s Sigma value are less than 6; For parameters pCO2, pO2and Na+, there exists significant difference between two quality control methods (P＝0.004 8,P＝0.000 1,P＝0.004 4,P＜0.01), other parameters pH, K+, Ca ++, Glu, Lac and Hct, there exists no significant difference between two quality control methods (P＝0.250 6, P＝0.062 3,P＝0.034 0,P＝0.346 9,P＝0.186 3,P＝0.823 1,P＞0.01).Totally 22 errors detected by iQM, includes 14 micro-clots and 8 interferences samples, which were not detected by traditional quality control .Conclusions The error in blood gas analysis mainly comes from the pre-analytical phase.iQM enhanced specimen inspection capabilities and make up for the inability of traditional quality control to monitor the quality of specimens , enabling full-scale, real-time, and dynamic monitoring of each specimen , powerful error detection capabilities , and automatic error correction capabilities . Besides, automatic documentation saves staff much time.The system can effectively ensure the accuracy of blood gas test results, meet the quality requirements of related laws and regulations and related industry standards , and also can meet the clinical intended use , providing new ideas for POCT quality management and improvement.
ABSTRACT
objective To evaluate effect of the Yishen-Tiaodu moxibustion combined with bladder training to treat neurogenic bladder after spinal cord injury operation.Methods 72 patients met the inclusion criteria of neurogenic bladder were divided into two groups according to random number table: a control group was treated with bladder training, and a treatment group on the basis of the control group was treated withYishen-Tiaodu moxibustion therapy. Both groups were treated for 3 months. The urodynamics as well as the change of urinalysis and kidney function were observed in both groups.Results The original bladder feeling (90.2 ± 6.9 mlvs. 53.1 ± 6.9 ml,t=22.812)、maximum urinary output(302.1 ± 37.8 mlvs. 207.7 ± 40.9 ml, t=10.170), the maximum bladder capacity (399.8 ± 74.1 mlvs. 330.9 ± 50.2 ml,t=4.619) in the treatment group were higher than the control group after treatment (P<0.01). Residual urine volume (82.9 ± 32.9 mlvs. 109.8 ± 51.8 ml,t=2.630) in the treatment group was lower than the control group (P<0.01); the 24h urinary protein (70.8 ± 9.1 mgvs. 96.3 ± 14.9 mg,t=8.763), Urea (5.7 ± 2.1 mmol/Lvs. 9.3 ± 2.9 mmol/L,t=6.033), Scr (100.8 ± 19.6μmol/Lvs. 119.2 ± 19.7μmol/L,t=3.973), BUN (5.2 ± 1.8 mmol/Lvs. 6.7 ± 2.4 mmol/L,t=3.000) in the treatment group were significantly decreased than the control group(P<0.01).Conclusions Yishen-Tiaodu moxibustion combined with bladder training could effectively improve urodynamics for the neurogenic bladder in patients with SCI, and decrease the incidence of urinary tract infections.
