Conjunction
2015-07-13
Definition: This field indicates that a second TQ1 segment is to follow. Refer To HL7 Table 0472 - TQ Conjunction ID in Chapter 2C, Code Tables, for allowed values.
For continuous or periodic services, the point at which the service is actually stopped is determined by the field TQ1-8 end date/time and TQ1-6 duration, whichever indicates an earlier stopping time. Ordinarily, only one of these fields would be present.

A | Asynchronous(Do the next specification in parallel with this one (unless otherwise constrained by the following fields: TQ1-7-start date/time and TQ1-8-end date/time). The conjunction of "A" specifies two parallel instructions, as are sometimes used in medication, e.g., prednisone given at 1 tab on Monday, Wednesday, Friday, and at 1/2 tab on Tuesday, Thursday, Saturday, Sunday.) |
C | Actuation Time(It will be followed by a completion time for the service. This code allows one to distinguish between the time and priority at which a service should be actuated (e.g., blood should be drawn) and the time and priority at which a service should be completed (e.g., results should be reported).) |
S | Synchronous(Do the next specification after this one (unless otherwise constrained by the following fields: TQ1-7-start date/time and TQ1-8-end date/time). An "S" specification implies that the second timing sequence follows the first, e.g., when a service request is written to measure blood pressure Q15 minutes for the 1st hour, then every 2 hours for the next day.) |
