BACKGROUND
Field of the Invention
Embodiments of the present invention generally relate to a hygiene monitoring system and methods thereof. More specifically, embodiments of the present invention relate to hygiene monitoring system for monitoring compliance to predetermined protocols related to hygiene.
Description of the Related Art
Many hospital-acquired (nosocomial) and food-borne infections are caused when individuals fail to exercise proper hand hygiene techniques. Infections are prevalent in all service facilities including hospitals, healthcare facilities, restaurants, food preparation facilities, and the like. When individuals fail to exercise proper hand hygiene techniques, they are more likely to carry microorganisms, including bacteria, that may cause infection. To reduce the incidence of these infections, proper hand hygiene techniques have been studied and standard protocols have been developed to reduce the risk of these infections.
Hand hygiene protocols have been designed to reduce the carriage of potential pathogens on the hands and decrease the incidence of preventable healthcare or food preparation infections, leading to a reduction in morbidity and mortality. Hand hygiene protocols may include, for example, a requirement that a user must wash his or her hands for a specified amount of time before and after an event, such as patient or food contact. To improve hand hygiene protocol compliance rates for these users, a need exists for an improved hygiene monitoring system and methods thereof.

In exemplary embodiments, the monitor 404 may comprise a timer that may be set off at the time of initiation of a procedure to improve hygiene. For example, when a sink 402 is turned on, the monitor 404 may begin the timer. In some embodiments, the monitor 404 may automatically initiate the timer. In alternative embodiments, the monitor 404 may be manually activated when the sink is turned on. For example, the monitor 404 may comprise a component either integral with the sink 402 or located in proximity to the sink 402 that detects when the faucet of the sink has been turned on by detecting the presence of water, by detecting the sink valves have been opened, and/or the like.
Although the monitor 404 is depicted in FIG. 4 as a separate apparatus, the monitor 404 may be integrated within a portion of the sink 402, or the like. For example, the monitor 404 may be integrated within the spout of the sink 402. When used in close proximity to a sink 402, the monitor 404 may comprise water-resistant, water repellant, and/or waterproof materials, and may be adapted to substantially prevent damage caused by water or other liquids. In some embodiments, the monitor 404 may be mounted, attached, or otherwise supported in proximity to the sink 402, a soap dispenser, and/or the like. In some embodiments, the monitor 404 may be adapted to monitor the amount of soap, or the like, that has been dispensed from a dispenser, or the like. This monitor may be adapted to notify maintenance staff when soap or hand hygiene materials are nearly exhausted and need replenishment.
In exemplary embodiments, the monitor 404 may provide and/or display an indication of the proper amount of time for scrubbing of hands to provide effective hand washing. In some embodiments, the monitor 404 may be provided with a default countdown time. For example, a default countdown time may be 20, 30, or 45 seconds, or the like. The default time may be adjusted as required by the needs at a specific location. The system 400 may provide an audio signal when hand washing starts and when it is completed. The system 400 may provide a video signal and a countdown of seconds until the completion of the minimum time for hand washing.
In some embodiments, the monitor 404 may be adapted to display information, audio, video, text, images, and/or the like that can be specified by a client. For example, a default video may display and/or demonstrate one or more proper hand washing techniques. The monitor 404 may also be adapted to display real time data, such as stock prices, sport scores, weather information, general advertisements, targeted advertisements, medical educational information, treatment option information, pharmaceutical product information, the number of patients in a hospital or census, the time, and/or the like. The monitor 404 may be adapted to display custom content set up by an administrator. In some embodiments, the custom content may depend upon a compliance rating of the user. For example, if a user has a compliance rating below a selected percentage, a training video, or the like, may be displayed to the user. In some embodiments, a user's compliance rating may comprise a percentage that the user complies with a hand hygiene protocol. In some embodiments, the user may be presented with targeted advertisements based on a user profile set up by the user and/or the administrator. For example, a specialist medical professional may be presented with targeted advertisements related to his or her specialty by the monitor 404.
The monitor 404 may be durable, appropriate for installation in medical locations, food preparation locations, locations wherein heavy use is anticipated, and/or the like. The monitor 404 may be in compliance with safety standards. For example, the monitor 404 may in compliance with the Underwriters Laboratories (UL) standard, and the European Exonomic Area (EEA) CE standards, and/or the like. The monitor 404 may comprise one or more elements that are cleanable and sanatizable. The monitor 404 may be adapted to be hung, mounted, placed, or otherwise displayed near existing sinks, preferably near existing soap dispensers.
In one embodiment, the monitor 404 may be incorporated in the soap dispenser and/or the faucet controlling the water for hand washing. The monitor 404 may comprise a power source. For example, the monitor 404 may be battery powered, and/or solar cell operated, to avoid the need to operate the device on routine grid electric power. In some embodiments, the monitor 404 may be powered by AC power and/or may comprise an AC connection for backup purposes if a battery fails or loses its charge. In some embodiments, the monitor 404 may be wired into the information grid and/or power grid of an end user. In exemplary embodiments, the monitor 404 system may be leased to one or more end users. As part of that lease, an administrator may be responsible for maintaining the functionality of the system 400, including replacement of batteries, maintenance, and/or the like, as needed.
In some embodiments, the monitor 404 may have a video display that may provide a countdown, and may provide other information relevant to the host institution in which the device is placed, or the like. Such information may comprise instructions in hand washing, for example, the 6 required poses for hand washing; other events to be promoted at the host institution; general information that is of interest, as a local weather report; advertising provided by the device supplier or the host institution, and/or the like. In some embodiments, the monitor 404 may connect to the Internet or an intranet wirelessly, to monitor battery life or to change or update information displayed on the device. The monitor 404 may be programmed and/or reprogrammed to update information displayed on the device, to change the number of seconds displayed for hand washing time, and/or to assess the battery life.
The monitor 404 may be adapted to identify the user. For example, the monitor 404 may allow a user to enter a unique identifying code into a keypad, touch screen, and/or the like. The monitor 404 may be adapted to identify a user by scanning a bar code, QR box, a radio frequency identification (RFID) tag on the individual's identification, digital fingerprint recognition and/or the like. The monitor 404 may be adapted to monitor the identified user's compliance with a hygiene protocol, for example, washing hands for a specified time period upon entering or exiting a particular area, at predetermined time intervals, at predetermined times, and/or the like. In some embodiments, every patient may have a unique identifier, such as a bar code, QR box, RFID, or the like, that may be added to existing identification cards. One or more rooms, instruments, and/or pieces of equipment may have similar identification by bar code, QR box or RFID, or the like. The monitor 404 may be communicatively coupled with a network for the collection, saving, and/or analysis of hygiene monitoring data.
The system 400 may provide ability to generate appropriately equipped identification cards on their sites. For example, the system 400 may comprise an ID or unique identifier generation means. The ID and/or unique identifier means may be coupled with a network and/or a central server for collecting and saving data related to each user of the system. For example, data related to each healthcare provider, each patient, each instrument, each room, each event, and/or the like may be collected and stored by the system 400. For every interaction between a healthcare provider and the monitor 404, a unique, time stamped, interaction number may be generated. This number may allow tracking of the hand hygiene episode, the patient, the healthcare provider, and may allow correlation with a specific patient care event. The number may be tracked by the monitor 404 system, and can also be sent to the healthcare provider and to the healthcare insurer, the hospital's data system and any other appropriately interested entity, for example, an accreditation agency. In some embodiments, specific incidents of infection may be tracked and a user that caused the infection may be identified. For example, when a patient experiences an infection and the patient has come into contact with a user that was not in compliance with a hand washing protocol within a period of time, the monitor 404 may indicate that it is likely the user caused the infection. In some embodiments, the monitor 404 may also track the amount of time a user spends on attending to a specific task to facilitate billing of the task.
The identification of an individual by the monitor 404 may allow the host institution to audit the location of hand washing, the timing of hand washing as related to some critical interaction, such as patient care, and or the like. The monitor 404 may perform audits of hand washing, or a remote server may audit hand washing and/or hygiene compliance data collected by the monitor 404. Hygiene audits performed by the system 400 may allow the host institution to better identify the causation of episodes of infection in the facility, and to track infections to specific individuals. The monitor 404 may comprise a camera to monitor hand washing skills. In some embodiments, the system 400 may compare the captured video of a user washing his or her hands with ideal hand washing techniques. For example, a computer vision program implemented in the system 400 may automate the monitoring of quality of hand washing skills.
A monitor 404 camera can be activated by the same action that sets off the hand washing timer or by other motion. The monitor 404 camera can be used to document that the worker under observation has properly used other infection control materials, such as gloves and gowns in hospital settings. The monitor 404 camera can either store the information in the device for later retrieval, or the information can be sent wirelessly via internet or intranet to a central server for analysis.
As the monitor 404 may have a way to identify individuals using the system 400, the monitor 404 can measure the time that an individual spends attending to a specific task or patient in a healthcare setting. This time measurement can facilitate billing activities in which time is measured, and quality assurance activities, and/or the like. When the monitor 404 is strategically located, the interaction of the monitored individual may be documented by the camera in the device, for facilitation of billing activities, quality assurance activities and tracking specific infections.
When the monitor 404 is communicating with a central server, real time assessments of the observed washing activity or other monitored activity may be made. The central server may comprise monitoring software to alert supervisors or interested individuals of lack of compliance with washing or other protocols, or other deviations from expected outcomes. In some embodiments, the central server may initiate automated contact with the responsible individual in the event of lack of compliance. The central server may initiate awards for individuals with predefined levels of compliance with host institution protocols. The award may be in the form of a coupon that may be printed by the monitoring device, or may be generated on the screen of the device for scanning by the observed employee/user, or may be sent by an automated contact to an email account or similar method of contacting the user. The system 400 may also tie compliance with host institution protocols to employee compensation or bonuses.
The transmissions of the device over the internet or intranet may be Health Insurance Portability and Accountability Act (HIPAA) compliant and properly encrypted, in healthcare installations. Healthcare host institutions may generate reports, or the like, of use compliance data using the system 400. The reports may be used to negotiate better reimbursement rates from insurers. Healthcare institutions can use compliance data and/or reports to negotiate better premium rates from malpractice liability providers. Healthcare regulatory agencies may use compliance data and/or reports to monitor infections by individuals and on an institution wide basis. Healthcare providers may license this data and/or reports, to demonstrate to patients and other third parties as a quality indicator. All information may be collected by the monitor 404 and/or the system 400 to be analyzed and to facilitate negotiations of savings as contemplated above, and to provide consultations in compliance in healthcare regulatory authorities.
In embodiments of the present invention, the healthcare provider may carry the monitor 404 device, as a modified smart cell phone. The monitor 404 may respond to RFID chips or other unique patient identification as a bar code, QR box or digital fingerprint, and may communicate with other components of the system 400, such as sink timers, soap dispensers, and/or the like. To help prevent spread of infection, the hand held device/smart phone may be surrounded by a shield that interferes with the growth of bacteria. The shield may comprise copper or silver, or the like.
To help prevent spread of infections, hospital apparel that interferes with the growth of bacteria, containing silver or copper or other suitable material, may be provided along with the monitor 404. The monitor 404 and/or the system 400 may collect and provide subscriptions to hand washing data and time data to insurers, so that they can confirm compliance with standard healthcare practices related to services provided to their insured clients. This system can also be used to prevent healthcare fraud and abuse by closer documentation of the performance of procedures.
The monitor 404 may collect and provide documentation of hand hygiene compliance for large customers (hospitals) and for individual users (doctors), which they may use for advertising or promotional activities. The monitor 404 and system 400 may provide infection consulting information and/or the ability to access services for clients. The monitor 404 may provide information and/or the ability to access consulting services in training staff on hand washing techniques.
In one example the monitor 404 may be adapted to monitor compliance with the World Health Organization's (WHO) five moments for hand hygiene. For example, the monitor 404 may be adapted to monitor compliance with the following procedure: before touching a patient, a healthcare worker may be required to pass by a beacon and/or other reader in a room or at the entrance to a ward, to document the first hand hygiene of the work day; a unique identifier may be placed on a kit to be scanned by smart phone app, or the like, before cleaning or aseptic procedures commence. A unique identifier may be placed inside the kit, or on the back of the kit, or the like, to be scanned at the time of the completion of the procedure. A unique identifier may be placed on patient care items such as intravenous fluid dressings, incontinence briefs or fluid collection bags, to be scanned prior to or after completion of the procedure for the patient. This would allow identification of a moment for hand hygiene at the time of the procedure.
A hand hygiene episode may be required to be recorded before and after a procedure. The hospital can collect this information using the system 400 for audit purposes. Healthcare payors may require this information for payment. For cases done in operating rooms, cards may be prepared and scanned by smart phone app, or the like, by healthcare professionals before and after procedure. Compliance with hand hygiene can be included in the mandated presurgical “time out” or “surgical pause”. The hospital may collect this information for audit purposes. Healthcare payors can require this information for payment. For body fluid exposure and risk of exposure, healthcare professionals may use a smart phone app, or the like, to scan a unique identifier on equipment that carries a risk, such as a Foley urine collection bag or a Jackson Pratt drain, or the like. Alternatively, the healthcare worker may scan a unique identifier posted in a room before and after the time of other services, as patient hygiene activities and toileting, or the like. This information can be used as part of quality control, efficiency of service provision, and for disability claims related to exposures to infectious body fluids. For example, if a healthcare worker could not document an exposure to an infected patient, they would not qualify for occupational disability.
After touching a patient, a specific time period, as thirty minutes, could be specified in which, if a healthcare worker, must complete hand hygiene procedures. If that time period expired, a hand hygiene procedure may be required by the system 400. After touching patient surroundings, a healthcare worker may have to “announce” himself or herself by RFID or unique identifier in a room, leading to a need for a hand hygiene event. The healthcare worker may have to signal going to bathroom or leaving immediate patient care activities, as break time or lunch time, triggering the need for another hand hygiene event. For visitors or vendors or other non-patient related hospital visitors, identification badges may be issued, that may trigger beacons, or the like, with audible beeps, or the like, on entering or leaving patient care areas.
Using the monitor 404 and a specific QR box code, bar code, other code, or the like, a healthcare worker may turn off the requirement for a hand hygiene moment when he or she may have walked by a beacon or stood by the opening to a patient room door without entering. Children visitors may have identifications linked to an adult parent or guardian. The adult may have to verify hand hygiene for the child. Access to the system 400 may be restricted by age. Pediatric patients or patients who are impaired and unable to provide for their hand hygiene may have identification linked to that of an adult parent or guardian. Healthcare workers or adults may have to verify hand hygiene for the child or impaired individual.

For ease, exemplary methods represented in FIG. 4 are described with reference to the client 105, server 115, and system 500 described above. The method 500 may be carried out using other embodiments as well. Many steps of the method 500 may generally be carried out by the system 500. A portion of the system 500 may be stored on a client 105, a server 115, or any other data storage location consistent with the present disclosure. It may be appreciated that the steps of the method 500 may be performed exclusively on the client 105 or partially on the client 105 and partially on the server 115. Any combination of shared computing power for performing the steps of the methods described herein consistent with the present disclosure is contemplated. For example, multiple clients 105 and servers 115 may collaborate to perform the steps of method 500.
The method 500 begins at step 510. At step 520, a monitoring apparatus 404 may be provided. An exemplary monitoring apparatus 404 is described herein with respect to FIG. 4. At step 530, a user may be indetiived by the system 500 and a monitoring process may commence. In some embodiments, the monitoring process may commence when a hygiene process is started. For example, when a sink 402 is turned on, a timer may be started and/or a camera may be activated, or the like. Data may be collected during the hygiene procedure with the monitor 404. The data may be related to a user's compliance with a predetermined hygiene protocol.
At step 540, information, text, video, animation, audio, a presentation, data, and/or the like may be displayed. For example, a countdown timer, a demonstration of a proper hand washing technique, local information, world news, and/or the like may be displayed. In some embodiments, the monitor 404 may not include a display. At step 550, monitoring of the hygiene process/procedure may end. In some embodiments, an indicator, such as a visual or audio indication may signal the end of the monitoring process to the user. At step 560, the monitoring data collected by the monitor 404 may be processed and analyzed by the system 500. In some embodiments, alerts may be generated when a user did not comply with a predetermined hygiene protocol. The alerts may be real-time, accessed on-demand, may be generated at predetermined time intervals, and/or may be indicated on reports generated by the system on predetermined dates. The alerts, or the like, may be printed in a report, displayed on a computer screen via an interface, or the like, transmitted via email, transmitted via text message, and/or stored in a database in accordance with embodiments of the present invention. After the hygiene procedure has concluded, the method 500 ends at step 570.
