In 88 of 1046 (8.4%) comparisons the a priori defined acceptable difference between POCT and the laboratory was exceeded occurring more often in epoc® (10.7% 95%CI:8.1,13.3%) compared with i-STAT® (6.1% 95%CI:4.1,8.2%)( p = 0.007). There were no instances of the laboratory reporting a critical value when POCT did not. In 4 of 646 (0.6%) comparisons, POCT reported a critical value but the laboratory did not with no statistically significant ( p = 0.323) difference between i-STAT® (0.9% 95%CI:0.0,1.9%) compared with epoc® (0.3% 95%CI:0.0,0.9%). Participants had a mean age of 58.7 years (SD16.3) 49% were female. Of 1649 episodes of care screened for enrollment, 174 required a blood draw, with 108 episodes (62.1%) enrolled from 73 participants.
Usability was analysed by survey of CP experience, a linear mixed effects model of Systems Usability Scale (SUS) adjusted for CP clinical and POCT experience, an expert heuristic evaluation of devices, a review of device-logged errors, and coded observations of POCT use during quality control testing. The difference of proportion of discrepant results between POCT and laboratory was compared using a two sample proportion test. In a CP programme responding to 6000 annual patient care events, a split sample validation of POCT against traditional laboratory analysis for seven analytes (sodium, potassium, chloride, creatinine, hemoglobin, hematocrit, and glucose) was conducted on a consecutive sample of patients. The purpose of this study was to compare the validity of two devices (Abbott i-STAT® and Alere epoc®) by CPs in the community. Point of care testing (POCT), as opposed to laboratory analysis, may offer a solution, but limited research exists on CP POCT.
