BACKGROUND: POCT urinalysis (UA) and urine pregnancy tests (UPT) are routinely performed in obstetrics and gynecology (Ob/Gyn) clinics by dipstick and pregnancy test kit methods respectively. In this study, we compared the time, efficiency and accuracy of these tests using manual, visually read methods and a semi-automated analyzer that was not interfaced to the EMR. METHODS: We prospectively enrolled 2525 patients at five Ob/Gyn clinics. Urine samples were tested using three different dipsticks for UA (2, 7 and 10 test pads) and the Sure-Vue™ urine pregnancy test kit. The samples were analyzed on the CLINITEK Status® Connect System and results compared for time taken and errors in results' transcription. RESULTS: Using the CLINITEK Status Connect System, average test time and average total test time for UA dipsticks 7 and 10 test pads was significantly less than the manual, visually read method (0.77 and 0.64 min, respectively; p < 0.001). The average test time for manual, visually read Chem 2 was significantly less than the CLINITEK Status Connect System (0.09 min; p = 0.005), but not the average total test time (0.08 min; p = 0.33). Average test time for a negative UPT using the CLINITEK Status Connect System was significantly greater (0.87 min; p < 0.001). We found a transcription error rate of 0.3-1.7% for UA results and none for UPT. About 8% of UA and 12% of UPT results were not documented in EMR. CONCLUSION: The CLINITEK Status Connect System was more efficient than the manual, visually read process and if interfaced with the EMR would eliminate errors and non-documentation of results.
