DETAILED DESCRIPTION

[0028] Systems and methods described here provide an approach that eliminates inefficiencies in locating a patient and avoids or simplifies any manual effort in keeping location up to date. Systems and methods further reduce errors in location by not relying on medical staff finding time to update systems during their schedule and automatically use location information for meaningful actions such as keeping family members informed or keeping medical staff updated automatically, continuously and in real time.

[0029] Bluetooth Low Energy (BLE) beacon technology is used for patient tracking in medical facilities, such as surgical centers, hospitals and nursing homes. A BLE beacon is attached to the patient wristband, medical chart or gown to track patient location. A preferred location to attach the BLE beacon is on the patient wristband.

[0030] BLE receivers are installed at various places inside the facility to listen to beacon transmits. These BLE receivers relay received beacons and their signal strength to cloud servers. Cloud servers use inputs from some or all BLE receivers inside a facility to determine the location of a particular BLE beacon and hence the patient.

[0031] BLE receivers in conjunction with cloud servers use existing indoor positioning technologies such as angle of arrival information, signal strength or triangulation to locate a beacon. Each beacon is uniquely paired with a single patient therefore finding the position of a beacon means finding the position of the patient paired with that beacon.

[0032] The system updates internal monitors and displays with patient location and status information relevant to medical staff. The system updates waiting room monitors and displays with patient status relevant to family members.

[0033] The system sends automatic SMS messages to family members depending on progress in patient journey. The system allows settings and configurations to specify conditions/trigger points for these automated messages. For example, a surgical center could configure the system to send automated messages to family members when surgery finishes and the patient has been moved to recovery room. Text messages can also be automatically sent when patient enters the operating room or is ready to see family members.

[0034] The system uses display input tablets (or touch screen TVs) where the list of patients shown is based on patient location. For example, tablets in pre-op nursing station show just the patient list in pre-op and a nurse could update status of that patient in just one-click.

[0035] Turning to the figures, FIG. 1 illustrates a high-level view of an entire patient management system provided herein. The system consists of at least one BLE beacon (101) attached to a patient wristband. BLE receiver cells (102a, 102b and 102c) are affixed at various locations inside the medical facility. The system further comprises a location determination server (107) and TV monitors/displays (105a, 105b and 105c) at various locations inside the medical facility as well as tablets (106a, 106b and 106c) installed throughout the facility and desktop (109) set up in the front desk.

[0036] BLE receiver cells 102a-b are affixed at various locations such that there is reliable coverage for locations where the patient may be. For the system to continue working even if a receiver (102a, 102b and 102c) is disconnected, redundant cells (102a, 102b and 102c) are provided at areas of the patient journey. BLE receivers (102a, 102b and 102c) collect beacon identification signals from beacons 101 in the vicinity and send this information to location server (107) along with the beacon MAC address and the signal strength at which the signal was received.

[0037] This information is sent over the public internet or private network over secure and private channels. The location server (107) calculates the beacon position and sends it to an application server (108). The application server (108) communicates to TV screens as well as tablets and computers within the facility and outside the facility. According to a preferred embodiment of the present invention, TV screen (105a) is installed at the surgical center waiting room (WR) and visualizes the patient location and status so patient family and others may learn of patient status by viewing the TV screen (105a) within the waiting room or elsewhere.

[0038] FIG. 2 illustrates a rendering of the waiting room TV screen (105a). The screen displays a list of patients (201) inside the surgical center along with their status (202). Patients names are displayed while meeting HIPPA (Health Insurance Portability and Accountability Act) rules and regulations. In this example, only patient initials (203) are shown. Alternatively, an alphanumeric code may be used as a unique identifier for the patient.

[0039] The status of patient (204) is shown in front of the initials. The patient location within the facility is derived from the information sent by location server (107) to application server (108). When a patient is in the Post-Anesthesia Care Unit (PACU) and the patient is ready to meet with family, a PACU nurse uses tablet (106b) in the PACU area to signal to the waiting room TV (105a) that the patient is awake and able to meet family.

[0040] As illustrated in FIG. 4, when the PACU nurse clicks on patient initials (402), screen (410) appears. By selecting button (408), the nurse can signal patient status on the waiting room TV. The entire row (205) of the waiting room TV with the patient initials and status changes color to green to signal to the family that the patient is ready to meet and that they need to talk to the front desk to be escorted to the PACU area.

[0041] Front desk personnel respond to the signal from the PACU nurse by selecting on “family ready” button (406) from their desktop computer (109) to signal to the PACU nurse that the family is moving to PACU area to meet the patient. Label (406) shows up on tablet (106b) to message to the PACU nurse that the patient family is in front of the PACU entrance or is ready to be picked up from the waiting room. At the same time label (811) illustrated in FIG. 8 appears on TV screens (105b) and (105c) to signal family readiness to see the patient.

[0042] The signaling and visualization scheme provided herein may save the front desk and the PACU nurses time. Personnel need not keep calling each other or walking back and forth between the waiting room and the PACU area to check on patient status and communicate patient information to family and others.

[0043] FIG. 3 illustrates the journey of patient (305) from (1) registration at waiting room (301) to (2) surgery preparation at pre-operative room (302). The patient continues to (3) surgery at operating room (304a) and to PACU room (303) for recovery and discharge.

[0044] FIG. 4 illustrates shows a user interface for a typical tablet (106b) deployed in PACU (303). Patients within the PACU area may be listed in the chronological order of their arrival at the PACU area. Displayed information includes the physician name (401), type of procedure (404), time spent in PACU (405), bed assigned to patient (403), and patient initials (402). To comply with HIPPA and convey information to staff members regarding patient identity, the system may display the patient identifier as full name, initials, first name only or an alphanumeric code.

[0045] Staff may choose how best to display patient information based on the location of the tablet or TV screen within the facility or based on other factor(s). When the PACU nurse selects a patient identifier, he/she is shown screen (410). The nurse is given options to assign a bed to the patient using button (407), to mark the patient as completed recovery and ready to meet family, or to discharge the patient with button (409). When the PACU nurse selects button (408), the patient name (205) on TV screen (105a) in the waiting room turns green.

[0046] Front desk personnel may respond by selecting “family ready” button (901) from desktop computer (109) to signal the readiness of the family to meet the patient in PACU. This causes indicator “family ready” (406) to show up on the tablet informing the PACU nurse that the patient is available in the waiting area or elsewhere. Indicator (811) on the PACU TV (105c) and PreOp TV (105b) may also appear to signal the readiness status of the waiting family.

[0047] FIG. 5 illustrates a user interface for a typical tablet (106a) deployed in the pre-operative area (302). Patients in the pre-operative area (302) may be listed in chronological order of their arrival. Displayed information includes the physician name (501), type of procedure (504), time spent in PreOp (505), bed assigned to patient (503), and patient initials (502). When the PreOp nurse selects a patient identifier, she/he is shown screen (510). The nurse is given the options to assign a bed to the patient using button (507) or button (508) to mark the patient as ready to see physician for OR consultation and interview. This action causes indicator (506) to appear on the tablet and indicators (813) to appear on TV screens (105b) and (105c).

[0048] FIG. 5 also exhibits button (515) that allows for a one-click notification via text messaging to the physician about the patient readiness for consultation in the PreOp area. Once the patient is approved by the physician to have surgery, the nurse selects button (509) to signal patient readiness to move to the operating room (OR) for surgery. This action causes indicator (514) to appear on the tablet and indicator (812) to appear on TV screens (105b) and (105c).

[0049] FIG. 6 depicts a sample user interface for tablet (106c) that is placed in the operating room. When the patient is detected in the OR, tablet (106c) changes from a screen showing icon “waiting for patient” to the user interface illustrated by FIG. 6. The physician name (614) is shown along with a notification bell (615) to allow for notifying the physician manually of the readiness of the patient for surgery.

[0050] Alternatively, when the patient enters the operating room, a text message is sent to the physician notifying the physician of patient readiness. Indicator (814) is simultaneously displayed on screens (105a) and (105b) so personnel involved with the subject surgery are updated about the event “patient entrance to the OR”. The tablet also shows the patient name (612) in full format, as initials, or as a unique alphanumeric identifier based on system settings. The interface also shows procedure type (613) and the duration of surgery (611) measured from the time the patient entered the operating room.

[0051] Actual time (602) is read from the application server (108) and used across the screens deployed within the surgical center as a synchronous common clock for the center. Block (603) represents the time at which the patient entered the operating room.

[0052] As surgery continues, the nurse selects button (609) to signal the start of the “Time Out” event. This event represents a recapitulation and reassurance of accurate patient identity, surgical site, and planned procedure. The status of block (610a) changes to show state (610b). Simultaneously, the state for block (808) depicted in FIG. 8 displayed on screens (105b) and (105c) changes to reflect the new status. Blocks (610a) on tablet (106c) and (808) on TV screens (105b) and (105c) remain synchronized and show the same state as surgery progresses. The nurse may select button (609) a second time to signal the start of the procedure.

[0053] Items labeled (610b-e) are depicted in FIG. 7. The status of block (610a) changes to show “ongoing” state (610c) indicating that the surgery is in progress. After the surgery is completed and “closing” starts, the nurse selects button (609) a third time to signal the start of “closing”. The status of block (610a) changes to show closing state (610d).

[0054] The patient's departure from the operating room is detected through the tracking system. Location server (107) signals the new patient position to application server (108). Block (610a) changes to state (610e) signaling that “room cleaning” event has started. A timer is displayed on the tablet (106c) to estimate turnover time of operating room. The cleaning crew stops the timer as soon as the room is cleaned and ready to receive the next patient. The estimated turnover time is stored in the application server (108) for subsequent evaluation and analysis.

[0055] FIG. 8 illustrates an interface displayed on TV screen (105a) placed in the PreOp area and screens 105(b) placed in the PACU area. Screens (105a-b) typically display the same interface at all times. Block 801 represents the operating room quadrant. The status of the surgery is shown by progress arrows (808). Statuses include “in OR” when patient enters OR, Time Out, Procedure Start and Closing. When the room is vacant it is illustrated by image (809). Inside quadrant (801) the system displays patient initials, doctor name, procedure type and time spent inside the OR.

[0056] The system also keeps a record of procedure events since the patient enters the room. This gives a detailed view of the status of the operating rooms within the surgical center and helps staff members to plan their activities based on patient status visualized live on screens (105a) and (105b). For example, nurses in PACU may rearrange their schedules when they see that patients are being delayed in the operating room.

[0057] Indicator (810) indicates surgery delays or late entries into the operating room. Quadrant (802) shows the list of patients in the waiting room. Quadrant (805) shows the list of patients and their status in the PreOp. Quadrant (806) shows the list of patients and their status in the PACU area. For each patient, the user interface (803) shows doctor name, patient initials, type of surgery, time spent by patient at the subject location.

[0058] FIG. 9 illustrates computer (109) viewable by front desk personnel. Front desk may have the task to register patients to the system and pair tracking beacon (101) with patient name (902). The list view of patients includes patient name, doctor name, procedure type and patient location. Button (901) allows front desk personnel to signal the readiness of patient's family to meet the patient. When button (901) is selected, label (811) appears on TV screens (105b). A beep or a special sound may be simultaneously emitted. Therefore, even when nurses are not looking at the TV screen, they are made aware of a status change. This gives PACU nurses information about family in the waiting room and ready to be accompanied to meet the patient. Button (903) allows front desk assistant to signal the readiness of patients to move to the PreOp.

[0059] When button (903) is selected, label (815) appears on TV screens (105b) signaling to the nurse inside the preOp to come and pick up the patient from the waiting room. This optimizes workflow between waiting room staff and preOp staff. Nurses in preOp can just monitor patient status from TV screens (105b) instead of going back and forth to waiting room or calling front desk to ask about patient readiness. The change of status of the patient may also be accompanied by a beep or special sound that nurses may become accustomed to. By hearing this sound, nurses will know that a patient is ready in preOp.

[0060] As the patient is tracked from waiting room (1001), to preop room (1002) to operating room (1003) to recovery room (1004), FIG. 10 depicts the types of information input performed by desktop (109), preOp tablet (106a), PACU tablet (106b) and OR tablet (106c). FIG. 10 also illustrates visualization parameters displayed on WR TV (105b), preOp TV (105b).

[0061] Input parameters are shown with a circled “I” next to the text in FIG. 9. These include the use of WR computer (109) for patient registration at waiting room (901) and for notifying PACU nurse that the patient family is ready. PreOp tablet (106a) is used to mark patient ready for physician or patient ready for OR. PreOp tablet (106b) is used to mark patient ready to see family or patient discharged. OR tablet (106c) is used to communicate surgery status including Time Out, procedure start, or closing.

[0062] Visualization parameters are shown with a circled “V” next to the text in FIG. 9. WR TV (105a) shows patient location and status as patient moves between different rooms of the surgery center. PreOp TV (105b) also visualizes patient location and status as patient moves between different rooms of the surgery center.

[0063] While the patient is in PreOp, PreOp TV (105b) visualizes patient readiness to see physician and patient readiness to move to the OR. When the patient moves to the OR, the PreOp TV (105b) shows surgery status for patient. When patient is in PACU, PreOp TV (105b) and PACU TV (105b) visualize patient's readiness to meet family.

[0064] FIG. 11 shows tracking the patient by a family member from smart phone (1101). As the patient moves between waiting room (301), to preop room (302) to operating room (304a) to recovery room (303), the phone renders patient journey by communicating with application server (108) and displaying patient status (1105) and the time (1102) of status change. Filled dots (1103) show locations visited by the patient while empty dots (1104) are used to show locations yet to be visited by the patient.
