The current COVID-19 pandemic has heightened the focus on infection prevention in hospitals. We evaluated hand hygiene compliance with alcohol-based hand rub via electronic observation among healthcare workers in an intensive care unit from 2017 to 2020. The COVID-19 pandemic was not associated with an increase in hand hygiene compliance.
This paper describes the methodology adopted at debis humaitá IT Services Latin America, for performing handling analysis commercial vehicles. Its application to an intercity bus with 3 axles is presented. The objective is to improve primary suspension characteristics alone, with respect to both comfort and handling and to study the behavior of the full vehicle with respect to handling and to improve it through the changes of primary suspensions characteristics. The methodology adopted was the development of a complete multibody model of the bus (Figure 4) in ADAMS, considering all the major non-linearities of the actual vehicle, such as air spring and shock absorber curves, suspension bump stops and tire model (Delft). Once having the model, several analyses were carried out including, modal, single lane change, double lane change, steering impulse and sine steering sweep. The results of these analyses were evaluated and modifications to the design were suggested in order to achieve the objectives of this work (to improve the primary suspension characteristics and also the handling behavior of the full vehicle). These modifications were implemented at a physical prototype and measurements have not been carried out yet. However, qualitative impression (not yet quantitative results), indicates an improvement in overall vehicle handling behavior.
Background:
Most hand hygiene (HH) intervention studies use a quasi-experimental design, are primarily uncontrolled before-and-after studies, or are controlled before-and-after studies with a nonequivalent control group. Well-funded studies with improved designs and HH interventions are needed.
Objectives:
To evaluate healthcare worker (HCW) HH compliance with alcohol-based hand rub (ABHR) through direct observation (human observer), 2 electronic technologies, a radio frequency identification (RFID) badge system, and an invasive device sensor.
Methods:
In our controlled experimental study, 2,269 observations were made over a 6-month period from July 1 to December 30, 2020, in a 4-bed intensive care unit. We compared HH compliance between a basic feedback loop system with RFID badges and an enhanced feedback loop system that utilized sensors on invasive devices.
Results:
Real-time feedback by wireless technology connected to a patient’s invasive device (enhanced feedback loop) resulted in a significant increase in HH compliance (69.5% in the enhanced group vs 59.1% in the basic group; P = .0001).
Conclusion:
An enhanced feedback loop system connected to invasive devices, providing real-time alerts to HCWs, is effective in improving HH compliance.
