Abstract

The present invention provides a workflow for patient scheduling in a Hospital Information System (HIS). While diagnosing a medical problem of a patient, a referring physician may refer a patient for certain exams. The referring physician places a request for ordering the exams with a scheduler that sent to the scheduler in the form of a decision tree. The decision tree includes a first set of exams and additional exams to be performed on a patient. The scheduler orders the exams by scheduling the exams with an acquisition modality and informs the patient about the schedule of the exams. The exams are performed on the patient and medical information from the exams is stored in an archive. The information is also sent to an analyst for analysis. The analyst analyzes the medical images and orders additional exams mentioned in the decision tree based on the results of an exam. The analyst requests additional exams until an end of the decision tree is reached.

supplementary exams to be performed on the patient in case the results of a parent exam match the expected results for the parent exam.

9. The method of claim 1, wherein an end of the decision tree is reached when a parent exam is reached that does not have any child exams which can be ordered by the analyst based on results of the parent exam, in the decision tree.

10. The method of claim 1, wherein the results of all exams are sent by the analyst to the referring physician, who reviews the results and completes the diagnosis of the patient.

4. The method of step 1, wherein ordering the requested exams comprises:

scheduling the requested exams with the acquisition modality; and

informing the patient about the schedule of the scheduled exams.

11. A method for processing a workflow for patient scheduling in a Hospital Information System, the method comprising:

sending a request for ordering exams to be performed on a patient to a scheduler, the request being sent by a referring physician in the form of a decision tree of exams to be performed on the patient, wherein the decision tree comprises;

additional exams to be performed on the patient based on results of exams which were performed on the patient;

exam specifications for all exams mentioned in the decision tree, the exam specifications for an exam specifying a manner in which the exam is to be performed; and

expected results for all exams mentioned in the decision tree;

ordering the requested exams, the order being placed by the scheduler with an acquisition modality, the acquisition modality being a system that can perform the ordered exams;

performing the ordered exams on the patient at the acquisition modality wherein performing the ordered exams comprises;

performing the ordered exams on the patient in accordance with the exam specifications to obtain medical images of the ordered exams;

storing the medical images of the ordered exams in an image archive; and

sending the medical images of the ordered exams to an analyst for analysis;

requesting additional exams to be performed on the patient based on an analysis of results of the ordered exams, the analysis being done by the analyst and the additional exams being requested by the analyst till an end of the decision tree is reached wherein requesting additional exams comprises;

analyzing the medical images to derive results of the ordered exams, the analysis of medical images being done by the analyst;

comparing the results of the ordered exams with the expected results of the ordered exams, the comparison of the results being performed by the analyst; and

requesting additional exams, as mentioned in the decision tree, to be performed on the patient based on the results of the ordered exams, the request for the additional exams being sent by the analyst directly to the scheduler; and

preparing an examination report and sending it to the referring physician, the examination report containing a final analysis of the results of all exams performed on the patient.

12. The method of claim 11 wherein each exam in the decision tree can be a parent exam of zero or more child exams and can also be a child exam of one or more parent exams.

13. The method of claim 11 wherein an end of the decision tree is reached when a parent exam is reached that does not have any child exams, which can be ordered by the analyst based on results of the parent exam, in the decision tree.

14. A method for processing a workflow for patient scheduling in a Hospital Information System, the method comprising the steps of:
