Clinical Instructions

New UI Visit Encounter (valid RC202109+)

Original Visit Encounter

Track all children ages 3-18 who had an outpatient or ED visit with a diagnosis of pharyngitis and an antibiotic ordered on or three (3) days after the visit. Compliance requires a group A streptococcus (strep) test be administered within the 7-day period from 3 days prior through 3 days after the initial diagnosis. Use either the Test and Procedures section of the encounter, or add the Lab Results - Set 2 to the encounter template; otherwise, enter the appropriate observation to the chart using the Observations chart tab.

Regardless of how the strep test observation is added to the chart, clients will need to ensure that the appropriate observation is configured with LOINC 6559-9.  Clients should search the Observation Codes editor for the Strep observations to determine if multiple observations need to be merged .
