Abstract

A computer-based surgical services management system for communicating between sites of a surgical services facility including a computer workstation located at each site of the facility, a server in network communication with each workstation, and a database resident on the network. The database retains patient-specific data maintained temporarily by the workstation located at a site where a patient is located, the patient-specific data moving from site to site with the patient, and site-specific data, maintained at the site where the site-specific data is produced. The database is distributed to and contained within each workstation for editing by a user. A copy of the database is contained in each workstation and is duplicated on the server. The database is of an object-oriented design containing classes for patients, locations, resources, surgeons and anesthesiologists. Methods are assigned to each of the classes for updating information. Methods also are assigned to perform constraint propagation in the network to maintain data structure. The workstations are in a peer-to-peer relationship. A copy of the database being contained on each of the individual workstations is also contained in the server. Changes to data made on each of the workstations are duplicated on the server and are updated to the other workstations periodically.

13. The system of claim 1, wherein the database further comprises:

personnel data for maintaining information regarding personnel, the personnel comprising surgeons, anesthesiologists, and nurses; and

equipment data for maintaining information regarding equipment used in relation to surgical services.

14. The system of claim 1, wherein information is written to text file to generate a transaction register.

15. The system of claim 1, further comprising:

means for inputting bar code information representing data specific to each patient;

means for providing time-of-day information; and

means for running a computer-based application for combining the bar code information and the time-of-day information to track and record residence and procedure times to produce an audit trail relative to a time course and geographic progression of a patient through surgical services, and whereby a transaction receipt is produced representing a written record for each patient of surgical services provided and who provided them.

16. The system of claim 1, further comprising:

utilization screens for locations in surgical services; and

time categories for locations in surgical services and displayed numerically or graphically on the utilization screens, the time categories being selected from the group consisting of;

available time,

scheduled time, and

actual time,

whereby actual utilization=actual time/available time, efficiency of utilization=scheduled time/actual time, and forecast utilization=scheduled time/available time.

17. The system of claim 1, wherein each workstation has a local hard disk memory device.

18. A computer-implemented method of managing data and for tracking, recording and communicating patient movement between site locations of a surgical services facility, the method comprising the steps of:

establishing a set of objects in which all relevant data relevant to an instance of an object exclusively are stored, the set of objects comprising;
