Method for controlling processes in a medical workflow system
View Patent ↗A system is described for managing data and information in a healthcare environment, such as a hospital. A handheld code scanner reads codes and either accepts data, or performs instructions based on the read code. The code scanner wirelessly transmits the codes or data to a central server which acts on the read code to carry out necessary functions. The system is useful for tracking patient data, such as for delivery of medicine. In addition, since the system can carry out instructions, it is useful for allowing healthcare workers to quickly and conveniently perform their duties without the necessity of sitting at a computer terminal.
1. A method of controlling processes in a medical workflow system comprising:
receiving a scanned code into a wireless terminal; and
analyzing said scanned code on said wireless terminal to determine whether said code corresponds to data or an instruction,
wherein if said code corresponds to an instruction, initiating a process, comprising:
(1) determining if said instruction is to be performed locally or on a server;
(2) wherein if said instruction is to be performed locally in said wireless terminal, executing said instruction in said wireless terminal, and wherein if said instruction is to be executed by said server, transmitting said code to said server for execution.
2. The method of claim 1 further comprising wirelessly transmitting said machine readable code to said server.
3. The method of claim 1 further comprising executing said instruction in said server.
4. The method of claim 3 , wherein executing said instruction controls a peripheral device.
5. The method of claim 1 , wherein said scanned code corresponds to a binary number comprising a plurality of bits, and wherein analyzing said scanned code comprises analyzing a value of one bit of said plurality of bits.
6. A method of administering medication to a patient in a medical workflow system comprising:
receiving a scanned code into a wireless terminal, wherein said code corresponds to medication administered to said patient;
initiating a latency timer in said wireless terminal in response to receiving said scanned code;
determining, within said wireless terminal, if a predetermined latency time has elapsed; and
generating an alert on said wireless terminal if said predetermined latency time has elapsed.
7. The method of claim 6 further comprising receiving a second code into said wireless terminal corresponding to patient data.
8. The method of claim 7 wherein said patient data includes at least one of heart rate and pain score.
9. The method of claim 6 , wherein said wireless terminal monitors for an indication of completion of patient lab tests.
10. The method of claim 6 further comprising wirelessly transmitting said scan code to a computer.
11. The method of claim 10 further comprising wirelessly receiving a response from said computer.
12. The method of claim 6 further comprising notifying a user periodically of said alert.
13. The method of claim 6 wherein said alert is a noiseless alert displayed on said wireless terminal.
14. The method of claim 6 wherein said alert is an audible alert.
15. The method of claim 6 further comprising notifying a user to enter additional information.
16. The method of claim 6 wherein said wireless terminal is a handheld device.
17. The method of claim 16 wherein said handheld device is configured to be operated with one hand.
18. A method of controlling processes in a medical workflow system comprising:
receiving a scanned code into a wireless terminal; and
analyzing said scanned code in said wireless terminal to determine whether said code corresponds to a patient vital sign or an instruction, wherein if said code corresponds to a patient vital sign, initiating a process, comprising:
(1) determining whether said patient vital sign is outside of predetermined parameters; and
(2) if said patient vital sign is outside of said predetermined parameters, generating a notification.
19. The method of claim 18 further comprising determining whether to display a warning on said wireless terminal.
20. The method of claim 18 further comprising determining whether to contact a system computer.
21. The method of claim 18 further comprising determining whether to wait for additional data or instruction.
22. The method of claim 18 , wherein said patient vital sign comprises a patient heart rate or a patient pain score.
23. The method of claim 18 , wherein said patient vital sign comprises patient temperature, method of administration of medication or location of administration of medication.
24. The method of claim 18 further comprising determining whether said scanned code corresponds to an approved patient medication.
