ABSTRACT
Objective:To analyze the application of PDCA mode in the management of blood transfusion waiting time.Methods:Using random block design, 98 patients received blood transfusion during January to December 2018 were included into the before improvement; 32 patients received blood transfusion during January to June 2019 were included into the after improvement. Standard process of blood taking and transfusion was applied to the before improvement, while based on standard process, found out the deficiencies in the previous clinical practice, continuously improved the details of the process for the after improvement. Then blood transfusion waiting times were compared between the two groups.Results:The blood transfusion waiting time was (26.95±9.20) min before improvement and (25.59±4.16) min after improvement, with a significantly lower disqualification rate 6.25% (2/32) comparing with 26.53% (26/98) before improvement. The differences were statistically significant ( t value was 3.75, P<0.01; χ2 value was 5.87, P<0.05). Conclusions:The application of PDCA circulation management mode can shorten the blood transfusion waiting time and transfusion can be made within 30 minutes after blood taking so that nursing quality of transfusion in the ward can be improved.
ABSTRACT
Purpose To investigate the imaging features of breast phyllodes tumor on mammography(MG),ultrasound(US) and pathology, correlated with its clinical manifestation.Materials and Methods Twelve cases of pathologically confirmed breast phyllodes tumors were examined by US and MG. The imaging findings were retrospectively analyzed. Results Of the 12 cases of breast phyllodes tumors, 6 were benign, 3 were malignant and 3 were borderline. MG predicted 3 breast phyllodes tumors, 3 breast carcinomas and 6 adenomas. US predicted 2 phyllodes tumors, 8 breast masses and 2 adenomas. Conclusion The imaging findings of phyllodes tumors on MG and US are characteristic but not specific. Combined application of both US and MG are helpful for early detection but can not differentiate its malignancy which is determined by pathology.
