## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority under 35 U.S.C. §119(a)-(d) or (f) to prior-filed, co-pending Indian patent application serial number 90/CHE/2009, filed on Jan. 12, 2009, which is hereby incorporated by reference in its entirety.
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to management of various healthcare resources and healthcare facilities in a healthcare environment, and more particularly to, a method and system for facilitating automated navigation in a healthcare environment. The invention is particularly useful in assisting patients in navigating in a healthcare facility.
2. Description of Related Art
Currently, a healthcare environment includes various healthcare resources, departments, healthcare facilities, clinicians etc located at different locations in the healthcare environment. For example, diagnostic labs, diagnostic equipments, emergency patient care room, admission and discharge section, billing facility, clinicians etc may be scattered at different parts of a hospital. Many times, in a healthcare environment such as hospital, the patient or the caretaker has to move from one locality to another, multiple times.
Mostly, the patient or the caretaker will consult a hospital staff to navigate to a desired destination. In a healthcare facility, there may be signboards indicating direction to various departments. But these signs boards give the patients or the caretaker an obtuse or vague navigation information and the patient may miss his way, as the intuitive details are not available.
Some of the hospitals have maps displayed indicating locations of various healthcare facility and resources. However if the patient is new to the hospital or if not able to understand the map or instructions provided along with it, the display of maps will not be helpful.
Further, the signboards and maps displayed are difficult to update and many times the maps or displays convey wrong navigation information to the patient, as they may not have been updated periodically.
Some of the solutions suggest, providing tracking devices with the patient as well as at the destination location. This will help, if the patient is in trauma and needs to locate a destination urgently. The tracking devices communicate with each other and the patient is navigated to the destination automatically. However, this requires providing tracking devices with the patient as well as at the destination and a server for managing the communication between them. Since the tracking devices are expensive and the information from both the tracking devices are required to navigate the patient efficiently, the process become more complicated and expensive. Thus it will be beneficial to have a simple and cost effective method for navigating in a healthcare environment.
Thus there exists a need to provide an improved method and system for navigating in a healthcare environment.

It should be understood that the various embodiments are not limited to the arrangements and instrumentality shown in the drawings.
Embodiments of the present invention assist a patient in navigating in a healthcare environment. To achieve this, an exemplary embodiment of the present invention utilizes a method of providing an identification device to the patient. The identification device communicates with a server or a healthcare information system (HIS) and obtains the navigation information corresponding to its destination. The identification device is provided only with the patients and is configured to convey the current location of the patient.
In an embodiment, an interactive healthcare facility map is generated with the details of healthcare facility and healthcare resources. This map is sent to the identification device and the same is stored in the identification device so that in the event of loosing communication with the hospital information system, the map can be retrieved by the identification device.
FIG. 1 is a block diagram of an automated navigation system as described in an embodiment of the invention. The system comprises a healthcare information system (HIS) 110 and an identification device 120. The HIS 110 is configured to receive patient information, healthcare facility information, healthcare resource information etc. Using the healthcare facility information and healthcare resource information, the HIS 110 may generate an interactive healthcare facility map. This map includes spatial direction and location to various healthcare facility and resources and also can have distance co-ordinate map of different locations. The HIS 110 may generate and store the map in a database. Alternately, an administrator may collect all the location information of healthcare resources, healthcare facility and generate a healthcare facility map and store it in HIS 110.
In an exemplary embodiment HIS maybe a server associated with a database and a processor as shown in FIG. 2.
In an embodiment, an identification device 120 is provided with each patient in the healthcare facility. The identification device 120 is configured to communicate with the HIS 110 in assisting patient in navigating within the healthcare facility. The identification device 120 communicates with the HIS 110 for obtaining navigation information corresponding to a destination.
In an embodiment, the identification device 120 includes a tracking device 122 operating based on tracking techniques such Radio frequency identification tag (RFID) based tracking device, Global positioning system (GPS) based tracking device, Infrared (IR) based tracking device, barcode based tracking device etc. The identification device 120 further comprises a communication interface 124, a memory 126 and a display 128. The tracking device 122 is configured to identify the current location of the patient and communicate the same to HIS 110 through the communication interface 124. Also, the identification device 120 may be provided with destination information. The destination information indicates, a desired destination facility or the resource to which the patient needs to navigate. An administrator may provide this information to the identification device 120. Alternately, the administrator may communicate patient information along with the destination to the HIS 110.
Each patient in the healthcare facility may be provided with an identification device 120. Before assigning it to each patient, the identification device 120 is configured using the patient identification information for that patient. In an example, a unique ID identifies each identification device 120 and the unique ID can be formatted using patient information. This unique ID may be provided with HIS 110 to identify the patient.
In the hospital or healthcare environment, a communication network is established for facilitating communication among various resources present in the healthcare facility. The HIS 110 may directly interact with the identification device 110 or may communicate through a server (not shown). If both identification device 120 and the HIS 110 are in the same communication network, they may establish communication through a wireless communication link 130 either directly or through a server. Once the communication is established, the identification device 120 communicates the current location of the patient along with the destination. Alternately, the destination may be sent to HIS 110 by an administrator separately, while giving the destination information to the patient.
In an embodiment, the destination information may be given to the identification device 120 by an administrator or by patient. The destination information along with the patient information may be conveyed to the HIS 110. The HIS 110 may verify the unique ID of the identification device 120 before establishing communication among them. Upon establishing the communication, the HIS 110 may send the facility map to the identification device 120, and the identification device 120 may store the same in its memory 126. The identification device 120 tracks the current location of the patient and sends it to the HIS 110. The HIS 110 with the help of the facility map and the current patient location and destination, navigation information corresponding to the destination is derived. In an embodiment, the navigation information may include the direction and distance to the desired location from the current patient location.
In an embodiment, upon getting the knowledge about the destination, the HIS 110 may forward information relevant to the destination to the patient. For example, if a patient is going to a dental clinic, relevant information such as nearest follow up center near to patient's residence, nearest pharmacy shop etc may be communicated to the patient. Also HIS 110 may communicate some general information such as location of nearest emergency room, restrooms etc on the way to the destination. Additionally, HIS 110 may communicate, some promotional articles related to the destination to the patient. For example, if a patient is moving to an ENT department, dental care promotions may be send to the patient.
In an embodiment, the navigation information is conveyed to the patient through the display 128. The display 128 may be visual and/or audio display. The navigation information may be displayed in a visual display such as a monitor, LED, display, CRT screen etc, but examples of display need not be limited to this. Alternately, the navigation information may be conveyed to patient in an audio display. The display 128 may be a speaker and the navigation information may be announced through the speaker to the patient. This will help to assist the patients who are not able to read and understand the navigation information from the display 128.
Once the destination is arrived, the identification device 120 may beep or vibrate.
Further, the identification device 120 and the HIS 110 may exchange the current location and navigation information continuously or at a preset interval. Optionally, as and when the patient get stuck somewhere, the patient may communicate with HIS 110 to obtain the navigation information. Also, the patient may query HIS for some relevant information from HIS.
Further more, to provide additional security, the identification device 120 may be provided with a password. The password may be formatted using patient specific information such as his blood group, biometric information, date of birth etc. However the password may be set at the patient's convenience. In case of establishing an initial communication or re establishing a communication with the HIS 110, the HIS 110 may ask for the password and verify the same before establishing the communication. Also the HIS 110 may verify the password periodically, to prevent misuse of the identification device 120.
In an embodiment, the patient may be faced with an emergency situation on the way to the destination. The patient may communicate this to the HIS 110. In an example the identification device 120 may be provided with an emergency button (not shown) and in case of an emergency, the patient can communicate with the HIS 110 by pressing the emergency button. Once the emergency button is pressed, the identification device 120 communicates the current patient location with an emergency signal to the HIS 110. The HIS 110 will identify the nearest emergency patient care room and communicate the patient location and patient information to the identified emergency room. The nearest emergency room location may be conveyed to the patient. The emergency room may establish a communication with the patient and a clinician may talk to the patient.
Additionally, the identification device 120 may be provided with a configurable button, configured to achieve different functionality. Alternately, the emergency button may be configured to perform different functions. The buttons may be programmable or can have different keys or touch panel to type in different queries and send it to the HIS 110.
In an exemplary embodiment, the identification device 120 may be associated with a patient moving device (not shown) such as wheelchair, patient table etc and the location information may be given to the patient moving device directly and the patient may be moved automatically to the desired destination.
In an embodiment, the HIS 110 may be provided with traffic information towards a healthcare facility. For example, in the event of patient heading towards an ENT department, the HIS 110 may communicate to the patient about the waiting information. This is achieved by providing the patient flow in the ENT department in real time to the HIS 110.
In an embodiment, an administrator may communicate with the patient through the HIS. In case administrator wanted to communicate to the patient urgently who is on his way to destination, the administrator may interact with the HIS and communicate the information that need to be conveyed to the patient to the HIS. The HIS may communicate this to the patient.
In an embodiment, any changes in the facility information or the resource information, it may be communicated to the HIS. If the information is relating to change in the location of the resource or facility, the same is updated in the interactive healthcare facility map. The updated map is communicated to the identification device 120. The update may be done in real time. The information might also include other relevant information relating to the resource and the facility. For example, if a resource is not operational or busy, the HIS may convey that to the patient and may suggest any other alternatives, if possible.
In an embodiment HIS 110 is any server in a healthcare environment, to which the identification device 120 can communicate wirelessly. The server might be associated with a database and a processor. The details are explained with reference to FIG. 2.

FIG. 3 is a flowchart illustrating an automatic navigation method as described in an embodiment of the invention. At step 310, an identification device is provided to each patient in the healthcare facility. The identification device is a configurable device and could be configured with a unique identification number derived from the patient information. The identification device identifies the current location of the patient. The identification device may communicate the current location of the patient to a healthcare information system (HIS). The identification device could also be protected using a password. In an example, the HIS could include a server associated with a database and a processor. At step 320, navigation information to a destination is generated with reference to the current patient location. The destination indicates the destination to which the patient needs to be navigated. This could be provided by the identification device or by an administrator. The server may access a database having patient information, healthcare resource information, and healthcare facility information. The server may also have an interactive healthcare facility map indicating the location of various resources and healthcare facility. This may be communicated to the identification device by the server, upon establishing communication between the server and the identification device. In an embodiment, the navigation information may be generated by a processor associated with the server, if the identification device is in communication with the server. Alternately, the identification device itself may generate the navigation information. For this the identification device uses the interactive facility map stored in its memory. Using the map and based on the current patient location, which is identified by the identification device, the identification device may generate the navigation information. At step 330, the navigation information is communicated to the patient. If the server is generating the navigation information such as distance and direction to the destination, the same may be communicated to the identification device. The identification device has various displaying method using which, the navigation information may be displayed to the patient.
FIG. 4 is a detailed flowchart illustrating a method of facilitating automated navigation in a healthcare environment as described in an embodiment of the invention. At step 405, an interactive healthcare facility map is prepared. This could be done by a healthcare information system or could be done by an administrator. At step 410, the interactive healthcare facility map is stored with the HIS. At step 415, an identification device is configured using patient information and a password. This will ensure that the identification device is configured with a unique identification number corresponding to the patient. In an embodiment, the administrator may also provide a destination to the identification device. At step 420, the configured identification device is provided to the patient. The identification device is configured to track the current position of the patient. At step 425, the identification device communicates the current location of the patient and the destination to the HIS. At step 430, HIS communicates the interactive healthcare facility map to the identification device. The healthcare facility map indicates details of healthcare facility along with the location of various healthcare resources. This may also have directional details. The identification device is configured to store this map in its memory as shown at step 435. At step 440, the identification device communicates the patient's current location and destination to the HIS. The HIS generates navigation information of the destination with reference to the current patient location, as at step 445. The navigation information such as the distance and direction to the destination from the patient's current location is being communicated to the identification device, as step 450. At step 455, the navigation information is displayed in the identification device. This may be displayed in audio or visual format. At step, 460, a check is made to ensure that the HIS and the identification device are still communicating. If they are still communicating, a check is made at step 465, to check whether the patient reached the destination. If not, the steps from 440-460 have been repeated until the patient reaches his destination. If the patient reached his destination, the identification device indicates the same as at step 495. However if the communication between the identification device and the HIS is lost, then the patient will be navigated with the help of the identification device. This illustrated in step 470-495. At step 470, a password is entered to the identification device, to ensure the proper usage of the identification device by the authorized person only. At step 475, the identification device confirms the password provided by the patient. At step 480, the healthcare facility map is being retrieved from the memory of the identification device. The navigation information calculated by the identification device or the map retrieved from the memory might be displayed to the patient as at step 485. A check is made to confirm whether the patient arrived his destination and if not, the process may repeat the steps from 470 to 490. Upon arriving the destination, the identification device indicates that the patient has reached the destination as at step 495.
