Interfacing of Point-of-Care Urinalysis Results and Errors

Supplementary File 1: Data for point-of-care urinalysis results entered into electronic medical record either manually or by electronic interface. The urinalysis analyzer was Clinitek Status Plus (Siemens Healthineers, Cary, NC) using either Multistix 10 SG or Uristix 4 (Siemens Healthineers) urinalysis strips. [Tab A]: Key for classes of errors (used in Tabs C-F) and example of errors for color and specific gravity. [Tab B]: Interfaced data choices for the urinalysis components. [Tab C]: Interfaced data. Urine color and clarity are interpreted by the operator, with the choices selected within the urinalysis instrument software and then transmitted by interface to the EMR. The remaining urinalysis results are read by the instrument and directly interfaced with the EMR electronically. The columns with error type use the number key in Tab A. [Tab D]: “Manual Pre-simplification” – These results are interpreted by the staff performing the test and entered into the EMR by selecting options from a series of drop-down menus. These tests were performed between January 2019 and September 2019. In October 2019, we restricted the number of options available in the provided drop-down menus to simplify data reporting and improve consistency. The columns with error type use the number key in Tab A. [Tab E]: Manual – Post-Simplification” – These data are similar to “manual pre-simplification” but occurred after the restriction in drop down menu options. The columns with error type use the number key in Tab A. [Tab F]: “Enter-Edit” – These results are interpreted by the staff performing the test and then manually entered into the EMR using free text without character restrictions. The following data (when available) were collected and found in Tabs B, C, D, and E: deidentified sample number, order description (either “Multistix 10”, “Uristix 4”, or “individual component"), age at time of testing (90 years or older reported as > 90), legal sex (male, female, or unknown), and urinalysis component data (color, clarity, glucose, bilirubin, ketones, specific gravity, blood, pH, protein, urobilinogen, nitrite, leukocyte esterase). The columns with error type use the number key in Tab A.
