Definitions

  • HAIs Healthcare-Associated Infections
  • a good personal protective equipment practice is important to reduce transmission of pathogenic microorganisms to patients and to protect workers (e.g., pursuant to Occupational Safety and Health Administration (OSHA) standards).
  • healthcare providers may wear various types of personal protective equipment, such as any one, any combination, or all of: gloves, mask, gown, or protective eyewear.
  • the personal protective equipment is placed outside of a patient's room for the healthcare provider to wear.
  • HH hand hygiene
  • PPE patient protective equipment
  • Example steps include any one, any combination, or all of: taking hand cleaning agent (e.g., taking hand sanitizer); taking PPE (e.g., opening a drawer or cabinet containing gloves, masks, etc.); performing one or more hand movements and/or the one or more hand movements in a sequence (e.g., performing hand rubbing for at least 20 seconds; upon entrance to a patient area, first cleaning hands prior to donning PPE; etc.).
  • hand cleaning agent e.g., taking hand sanitizer
  • PPE e.g., opening a drawer or cabinet containing gloves, masks, etc.

  • PPE e.g., opening a drawer or cabinet containing gloves, masks, etc.
  • taking sanitizer from a dispenser may comprise a HH action and may be a trigger identifying a HH action.
  • opening a drawer that contains gloves may comprise a hygiene action and may be a trigger identifying a PPE action.
  • the trigger for the hygiene action may comprise a predicate step (such as an initial step) in order for the healthcare provider to comply with the protocol (e.g., the healthcare provider performing the predicate step of taking sanitizer in preparation for rubbing hands to comply with the HH protocol; the healthcare provider performing the predicate step of opening the drawer containing gloves in preparation for putting on the gloves in order to comply with the PPE protocol).
  • the hygiene opportunity may comprise an opportunity for practicing proper hygiene with a patient that may be identified based on identifying behavior indicative of patient interaction associated with one or more hygiene opportunities.
  • a hygiene action comprises an event for performing proper hygiene.
  • the hygiene action may be detected in one of several ways, such as by sensing one or more of the acts for complying with the hygiene action, including by: detecting sanitizer being dispensed from a dispenser; detecting opening/taking of PPE from a PPE container.
  • a healthcare worker may potentially have dozens or hundreds of interactions with others in the course of a single day.
  • a subset of those interaction are identified as being hygiene opportunities, which may be those interactions where guidelines, such as the WHO guidelines, are to be followed.
  • the hygiene actions, with the various steps following those guidelines, may, in turn, be used to determine compliance.
  • reminders may be generated for healthcare workers according to any one, any combination, or all of the following: responsive to identifying a hygiene opportunity; responsive to identifying a hygiene action; responsive to identifying both a hygiene opportunity and a hygiene action; responsive to detecting a hygiene opportunity and responsive to a determination of compliance or non-compliance with the hygiene opportunity (e.g., providing a reminder as feedback indicating non-compliance (e.g., failure to take sanitizer), indicating partial compliance (e.g., taking sanitizer but failing to perform the requisite 20 seconds of hand rubbing required by the HH protocol); and/or indicating full compliance (e.g., full compliance with one or both HH protocol or PPE protocol); or responsive to detecting a hygiene action and responsive to a determination of compliance or non-compliance with the hygiene action.

Responsive to identifying the opportunity (and before any determination of partial or full compliance), an output may be generated to remind the healthcare worker as to the hygiene protocol associated with the area.
  • the area may have a changing hygiene protocol (e.g., the hygiene protocol(s) associated with the patient room change based on the diagnosis of the patient assigned to the patient room).
  • a reminder may be output as to the changing hygiene protocol (e.g., responsive to identifying the healthcare worker exiting the patient room, generating an output as to the HH protocol to use soap/water to clean hands (the HH protocol associated with the patient room due to a diagnosis of the patient in the patient room)).

  • a failure to detect the predicate step within a certain time period of identifying the HH opportunity results in generating an output indicative of a reminder to perform the predicate step (e.g., an output indicative to "take sanitizer").
  • an output may be generated (e.g., failure to detect hand rubbing for at least 20 seconds required by the hand hygiene protocol results in an output being generated indicative to the healthcare provider to rub for at least 20 seconds; failure to detect a certain hand rubbing motion required by the hand hygiene protocol results in an output being generated indicative to the healthcare provider to perform the certain hand rubbing motion; failure to detect a proper sequence (e.g., failure to perform hand sanitizing/PPE in proper sequence); etc.).
  • the output may be generated on a mobile electronic device associated with the healthcare provider (e.g., a wristband) and/or on a stationary controller associated with the patient area, as discussed further below.
