Abstract

A system automatically updates a patient medication administration schedule in response to a healthcare worker entering data into an information system identifying a time at which a medication was administered to the patient. A medication administration information system comprises a processor for maintaining a schedule identifying a first nominal time for administering a first medication to a patient. The first medication is scheduled for administration to the patient subsequent to administration of a second medication to the patient. The processor updates the schedule by re-calculating the first nominal time for administering the first medication to the patient to provide a re-calculated time in response to received information identifying at least one of, (a) a late administration of the second medication to the patient and (b) an early administration of the second medication to the patient. The late and early administration being relative to a second scheduled nominal time for administering the second medication to the patient. A display generator initiates generation of data representing at least one display image including the re-calculated time for administering the first medication to the patient.

Claims

1. A medication administration information system, comprising:

a processor for,

maintaining a schedule identifying a first nominal time for administering a first medication to a patient, said first medication being scheduled for administration to said patient subsequent to administration of a second medication to said patient and

updating said schedule by re-calculating said first nominal time for administering said first medication to said patient to provide a re-calculated time in response to received information identifying at least one of, (a) a late administration of said second medication to said patient and (b) an early administration of said second medication to said patient, said late and early administration being relative to a second scheduled nominal time for administering said second medication to said patient; and

a display generator for initiating generation of data representing at least one display image including said re-calculated time for administering said first medication to said patient.

2. A system according to claim 1, wherein

said processor re-calculates said first nominal time for administering medication to said patient by shifting a scheduled administration time of said first medication by at least one of, (a) a period substantially comprising a time duration of said late administration of said second medication to said patient and (b) a period substantially comprising a time duration of said early administration of said second medication to said patient.

3. A system according to claim 1, wherein

said processor re-calculates said first nominal time for administering said first medication to said patient by shifting a scheduled medication administration time and approximating a shifted time to a predetermined interval boundary time.

4. A system according to claim 3, wherein

said predetermined interval boundary time is a time occurring at an interval boundary comprising at least one of, (a) a 5 minute interval boundary, (b) a 10 minute interval boundary, (c) a 15 minute interval boundary, (d) a 30 minute interval boundary, (e) a one minute interval boundary and (f) a 1 hour interval boundary.

5. A system according to claim 1, wherein

said processor determines a value substantially representing a time difference between said second nominal time for administering said second medication and at least one of, (a) a time of said late administration of said second medication and (b) a time of said early administration of said second medication and

said processor re-calculates said first nominal time if said value exceeds a first predetermined threshold value.

6. A system according to claim 5, wherein

said processor re-calculates said first nominal time if said value is less than a second predetermined threshold value.

7. A system according to claim 1, including

a message generator for generating a message for communication to a remote system, said message indicating said schedule is updated with said re-calculated time.

8. A system according to claim 7, including

said message is usable by a medication management information system to indicate a change in time for preparation of a medication.

9. A system according to claim 7, wherein

said message is communicated to update a medication order processing system to indicate said re-calculated time for administering said first medication.

10. A system according to claim 7, including

said message is usable by a medication management information system to adjust time for distribution of a prepared medication.

11. A system according to claim 7, including

said message is used in preparing a label for use on a prepared medication.

12. A system according to claim 1, wherein

said processor inhibits update of said schedule in response to a determination of at least one of, (a) an order for administration of said first medication has been discontinued, (b) an order for administration of said first medication has reached its stop date, (c) an order for administration of said first medication requires repeated separate administration operations, (d) an order for administration of said first medication has been revised, (e) an order for administration of said first medication indicates no further administration is required and (f) an order for administration of said first medication initiates administration after said recalculated time.

13. A system according to claim 1, including

an inventory manager for updating a medication inventory in response to said updated medication administration schedule.

14. A system according to claim 1, wherein

said medication comprises at least one of, (a) an IV infusion fluid, (b) an orally administered medication, (c) an injected medication and (d) a medication applied externally to a patient'"'"'s body.

15. A system according to claim 1, wherein

said first medication and said second medication are separately scheduled doses of the same medication.

16. A system according to claim 1, wherein

said first medication and said second medication are separately scheduled doses of different medications.

17. A medication administration information system, comprising:

a processor for,

maintaining a schedule identifying a first nominal time for administering a first medication to a patient, said first medication being scheduled for administration to said patient subsequent to administration of a second medication to said patient and

updating said schedule by re-calculating said first nominal time for administering said first medication to said patient to provide a re-calculated time in response to received information identifying at least one of, (a) a late administration of said second medication to said patient and (b) an early administration of said second medication to said patient, said late and early administration being relative to a second scheduled nominal time for administering said second medication to said patient; and

a task manager for updating a record indicating a task sequence to be performed by a healthcare worker in response to said updated schedule.

18. A system according to claim 17, wherein

said processor initiates a clinical safety check, substantially at said re-calculated time, said clinical safety check being for determining safety of administering said first medication to said patient.

19. A system according to claim 18, wherein

said clinical safety check comprises at least one of, (a) a determination whether said patient is allergic to said first medication, (b) a determination whether said first medication interacts with another medication taken by said patient and (c) a determination whether said first medication conflicts with another medication taken by said patient.

20. A system according to claim 17, wherein

said received information is derived from data comprising a bar code scan of a second medication identifier and a bar code scan of a patient identifier.

21. A system according to claim 20 wherein

said received information is derived from a user entered time of second medication administration.

22. A method for monitoring medication administration, comprising the activities of:

maintaining a schedule identifying a first nominal time for administering a first medication to a patient, said first medication being scheduled for administration to said patient subsequent to administration of a second medication to said patient;

updating said schedule by re-calculating said first nominal time for administering said first medication to said patient to provide a re-calculated time in response to received information identifying at least one of, (a) a late administration of said second medication to said patient and (b) an early administration of said second medication to said patient, said late and early administration being relative to a second scheduled nominal time for administering said second medication to said patient; and
