Accurately understanding the knowledge-attitude/belief-practice (KAP) level of nurses in Nyingchi area on blood glucose management is of great significance to the development of blood glucose monitoring management guidance for nurses in this area. Therefore, this study investigated the current status of the management of blood glucose monitoring management standards for clinical nurses in Nyingchi, Tibet. Objective: To investigate and analyze the current situation of clinical nurses in Nyingchi region of Tibet to grasp the regulation of blood glucose monitoring and guide the implementation of the norm of blood glucose monitoring for clinical nurses. <strong>Methods: </strong>The research survey was carried out from March to April 2020. Random sampling method was used to select 134 clinical in-service nurses in Nyingchii, Tibet. The self-designed knowledge-attitude/belief-practice survey questionnaire for clinical nurses’ blood glucose monitoring and management in Tibet was used. Nurses’ blood glucose monitoring management “KAP” scores and related influencing factors are analyzed. <strong>Results: </strong>Blood sugar monitoring and management knowledge score is (36.78 ± 6.80), attitude dimension is (42.48 ± 6.42), practice dimension is (61.87 ± 10.24) and total score is (304.73 ± 36.24). The nurse’s department and whether to participate in diabetes training are the main influencing factors of the blood glucose monitoring management norms, knowledge and behavior (both P < 0.05). <strong>Conclusion: </strong>The standard knowledge of blood glucose monitoring and management of clinical nurses in Nyingchi region of Tibet is at the middle level, positive attitude and unsatisfactory behavior. Nursing managers should conduct standardized training for clinical nurses in blood glucose monitoring, develop the training mode of diabetes specialty nursing talents in Nyingchi area, and construct a complete management system of diabetes specialty nursing.展开更多

Glucose concentration in interstitial fluid is closely related to the blood glucose levels. Minimally invasive continuous blood glucose monitoring technology based on the glucose detection in interstitial fluid develops rapidly and gets more and more attentions from the patients and the doctors,due to its instantaneous real-time display of glucose level,"24/7"coverage,and the ability to characterize glycemic variability. According to the different detection methods,most of the continuous glucose monitoring technology could be divided into two kinds: subcutaneous implantation method and transdermal extraction method. This paper review s the recent development of minimally invasive blood glucose monitoring technology and instruments. The mainly remained challenges and related research directions are presented as well.展开更多

文摘Objective:To evaluate the accuracy of Roche Accu-Chek Performa glucose meters at a low glucose concentration of<5.55 mmol/L(100 mg/dL)over a 9-year period.Methods:The accuracy of the Roche Accu-Chek Performa glucose meters at low glucose concentrations was evaluated using annual comparison data for 9 consecutive years from 2015 to 2023,according to the acceptability criteria specified in International Organization for Standardization(ISO)15197:2013.Blood samples with low glucose concentrations of<5.55 mmol/L were prepared by incubation and glycolysis.The glucose concentration was detected using Roche Accu-Chek Performa glucose meters and a biochemical analyzer in the central laboratory.Results:A total of 2978 pairs of comparison results from 211 glucose meters at a low glucose concentration of<5.55 mmol/L were retrospectively analyzed from 2015 to 2023.The clinical use duration spanned from 1 to 9 years and 40.76%(86 out of 211 glucose meters)had been used for more than 2 years.The correlation coefficient r between glucose meter measurements and laboratory reference values was 0.98(p<0.001).The mean according to Roche Accu-Chek Performa glucose meters was 0.05 mmol/L(0.9 mg/dL)higher than that of the biochemical analyzer(Z=-13.82,p<0.0001).The results showed that 100.00%(211 out of 211)of the Roche Accu-Chek Performa glucose meters met the acceptability criteria specified in ISO 15197:2013.At a low glucose concentration of<5.55 mmol/L,99.90%(2975 out of 2978)of the comparative data pairs in the error distribution fell within the range of±0.83 mmol/L(15 mg/dL).Parkes consensus error grid analysis showed that 100.00%(2978 out of 2978)of comparative data pairs fell within region A.Conclusions:This study demonstrated that Roche Accu-Chek Performa glucose meters successfully met the accuracy standards of ISO 15197:2013 for measuring blood glucose within the hypoglycemic range.Greater attention should be given to the performance of blood glucose monitoring systems in the low glycemic range,especially for patients with diabetes who are prone to hypoglycemia and require precise measurements.
