Cerner Community Works EMR Tip Sheet August 2023 LAB Orders and Timed Studies
Lab Orders are dependent on the Collection (Start) Date/Time, Priority, Frequency, and Duration selected. Collection (Start) Date/Time initiates the order, for example an order with a specific start date/time would not be initiated until that date/time. It does NOT mean an order will be scheduled for that exact time – unless it is a ONE time order (ONCE Frequency). TIMED STUDIES are for labs that need to be collected at a precise time. Priority tells the Lab system WHEN Add On, Expedite (Now), and STAT Orders should only be used with ONCE Frequency (For example: you CANNOT have an Add On, Expedite, or STAT Order now and then q8hrs- it is no longer STAT) Routine & Timed Study Priority can be used with ONCE Orders or with a SERIES ( q4hr , q6hr(Sch), etc)
Frequency tells the Lab system HOW OFTEN There are 3 types: Once Frequency, Regular Frequency (NO sch), and Scheduled (sch) Frequency (1) Once (single order) – One time at Collection Date/Time Entered – the current date/time is the default but can be adjusted as needed. Once Frequency should always be used with Add Ons, Expedites, and STATs (2) Regular series frequencies (NO sch) will pick up the schedule the first time the scheduling job runs after the start date/time. The tests are scheduled at the chosen intervals. (3) SCH frequencies with (sch) behind the hr, such as every 4 hr (sch) – functions just like a ROUTINE Lab – scheduled draw times will be adjusted to a preset specific LAB Schedule after the start time.
Examples of Timed Studies :
Scheduled (sch) Frequency for every 3 hr (sch) – will convert to preset specific LAB Collect times. Every 3 hr (sch) Lab schedule is set for 15:00; 18:00; 21:00; etc. If you miss these specific times by even 1 minute the Lab system will not pick up your order until the next 3 hour scheduled (sch) runtime.
Example of a Timed Study Frequency (no sch) for every 3 hours; placed at 13:10 start time – scheduled for 13:10; 16:10; 19:10; 22:10; etc…. THIS IS WHAT YOU WANT FOR PRECISE TIMES
It is very important that you communicate with LAB anytime critical tests are needed and you are not sure if the system is scheduling the test correctly. Remember “ sch ” will mean Lab ’ s Routine times .
