Method for assessing improvement in hand hygiene practices

InactiveUS20070008146A1Easily employedLow costData processing applicationsHealth-index calculationHand partsIntervention program
A method for assessing improvement in hand hygiene practices using sanitation solution dispensers deployed within particular areas of interest in a healthcare facility or the like. Each of the dispensers has a counter associated therewith, with the counter producing a count indicative of actual events of a healthcare worker sanitizing his/her hands. Other data is acquired that impacts the number of anticipated hand sanitation events in this particular area of interest. From this data, a number of anticipated hand sanitation events is determined. Finally, a determination is made, from information obtained through actual observation, of the number of opportunities that healthcare workers will have for hand sanitation in the area of interest over a particular period of time. A performance index, indicative of compliance with hand hygiene protocol, is then obtained by dividing the difference between the actual number of hand sanitizing events and the number of anticipated hand hygiene events by the number of opportunities for such hand hygiene events. This index may then be used to gauge improvement or regression in hand hygiene practices in an area of interest, or to measure the effectiveness of intervention programs, or to compare performance between various areas of interest.

System and method for constraining a graphical hand from penetrating simulated graphical objects

An apparatus, system, method, and computer program and computer program product are provided for constraining the movement of a graphical hand when the physical hand controlling the graphical hand does not have a similar physical constraint. The constraining technique may comprise use and analysis of a revolute-joint-link-spring model. In such a model, an uncompressed/unextended spring position represents the corresponding measured joint angle or link position. In addition to linear springs which follow Hook's Law, i.e., F=k*x, non-linear springs or other non-linear force functions may be employed to obtain the desired result of allowing a graphical joint or link to deviate from what the corresponding measured joint or link provides. In particular, if a graphical hand configuration corresponding to measured joint and link positions causes a portion of the hand to penetrate a simulated graphical solid object, a mathematical determination is used to compute modified joint and link positions such that the graphical hand part will no longer penetrate the graphical solid object. Such a constraint technique may include solving a spring model such that the various joint and link springs compress or extend to produce modified joint and link positions. Such a constraint technique may also be applied to constrain other graphical body parts and graphical inanimate objects, where corresponding physical controlling, i.e., measured, body parts and inanimate objects do not possess a similar constraint or impediment.
