“…Arterial samples compared with capillary samples. Some ICU studies using arterial samples measured with the POC device show acceptable agreement with capillary blood (70,71). A recent abstract found that with newer POC devices in ICU patients, arterial samples had greater accuracy than capillary whole-blood compared with the central whole-blood method (72).…”

“…Although POC devices for glucose testing are calibrated for use with capillary fingerstick blood, clinicians often obtain blood for POC testing from indwelling arterial or central venous catheters (CVCs). Despite the frequency of this practice, few clinical studies [4][5][6][7][8][9][10] have been done to evaluate the performance of POC glucose devices with blood from indwelling catheters. Several of the studies had serious methodological problems, including small sample size, 4 poorly described methods, 5,9,10 and inappropriate statistical analysis.…”

“…Several of the studies had serious methodological problems, including small sample size, 4 poorly described methods, 5,9,10 and inappropriate statistical analysis. 5,6,10 differences occurred between the reference glucose value (laboratory glucose) and the POC glucose values (CVC and fingerstick blood). Differences (bias) and limits of agreement (precision) between the POC glucose meter (CVC and fingerstick) and reference standard glucose values were calculated and graphed by using the Bland-Altman method.…”

“…[4][5][6][7][8]10,[19][20][21][22][23][24][25][26][27] In most of those studies, however, POC glucose testing was done with fingerstick blood; blood was obtained from an existing catheter device (arterial catheters) and appropriate statistical analysis was done in only 2 studies. 7,8 Our study extends the findings of significant differences between POC and laboratory glucose analysis to CVC blood.…”

Background Blood for glucose analysis is often obtained interchangeably from indwelling catheters and fingersticks. Objectives To determine the level of agreement between glucose values obtained by laboratory analysis and with a pointof-care device for blood from 2 different sources: fingerstick and a central venous catheter. Methods A method-comparison design was used. Point-of-care values for blood from fingersticks and catheters were compared with laboratory values for blood from catheters in a convenience sample of 67 critically ill patients. The effects of hematocrit level and finger edema on differences in glucose values between the 2 methods were also evaluated. A t test was used to determine differences in glucose values obtained via the 2 methods. Differences and limits of agreement were also calculated. Results Laboratory glucose values for blood from a catheter differed significantly from point-of-care values for blood from the catheter (t 1,66 = -9.18; P < .001) and from a fingerstick (t 1,66 = 6.53; P < .001). Glucose values for the 2 methods differed by 20 mg/dL or more for 1 of 6 patients (15%) for catheter samples and for 1 of 5 (21%) for fingerstick samples. Point-of-care glucose values for fingerstick and catheter samples did not differ (P = .98). Hematocrit level significantly explained the difference in glucose values between the 2 methods for both catheter (R 2 = 0.288; P < .001) and fingerstick (R 2 = 0.280; P = .02) samples. Conclusions Notice to CE enrollees:A closed-book, multiple-choice examination following this article tests your under standing of the following objectives: 1. Describe the relationship of euglycemic glucose levels to outcomes for critically ill patients. 2. Understand the importance of differences between point-of-care (POC) glucose testing and laboratory glucose testing used with critically ill patients. 3. Recognize the relationship between hemoglobin levels and the accuracy of POC test values for blood glucose.

Background Blood for point-of-care analysis of glucose levels is often obtained from different sources (fingerstick, arterial or central venous catheter). Objectives To examine agreement between point-of-care and laboratory glucose values and to determine effects of hematocrit, serum carbon dioxide, and mean arterial pressure on the accuracy of point-of-care values. Methods Point-of-care values were compared with laboratory values. In 49 critically ill patients, blood was obtained first from a catheter for laboratory testing and then from the catheter and via fingerstick for point-of-care testing. Bias, precision, and root-mean-square differences were calculated to quantify differences in values between the 2 methods. A t test was used to determine differences in values between each point-of-care blood source and the laboratory value. Multiple regression analysis was used to determine if serum level of carbon dioxide, hematocrit, and/or mean arterial pressure significantly contributed to the difference in bias and precision for the point-of-care blood sources. Results Mean laboratory glucose level was 135 (SEM 5.3, range 58–265) mg/dL. In point-of-care testing, bias ± precision and root-mean-square differences were 2.1 ± 12.3 and 12.35, respectively, for fingerstick blood and 0.6 ± 10.6 and 10.46 for catheter blood. Values for point-of-care and laboratory tests did not differ significantly. For catheter samples, hematocrit and serum carbon dioxide contributed significantly to difference scores between point-of-care and laboratory values (P < .001). Conclusions Glucose values for point-of-care samples did not differ significantly from laboratory values. For catheter samples, hematocrit and serum carbon dioxide levels accounted for the difference between point-of-care and laboratory glucose values.
