About Me

  • I'm a Ph.D. student in Architecture at Georgia Tech, specializing in the area, ACB (Architecture, Culture, and Behavior). I got my Bachelor's degree in architectural engineering and had some time for practice back in Korea and came here at Tech for the professional degree in Architecture. Currently I'm very intersted in the role of physical environment such as addressing the needs of care model & process and then, involving in enhancing process and quality of care.
  • I'm also a mother of 16 months old boy! He is a very healthy and happy boy! I can't imagine being in a hospital with him... Just imagining that is quite terrifying... It would be out of imagination being actually in a hospital with the little one... I hope I can really understand their (families and children) feelings and needs and can reflect those into the design of the pediatric health center.

Research related to handwashing

Environmental intervention

  • Hand washing is improved by increasing the ratio of the number of sinks or hand-cleaner dispensers to beds (Cohen et al, 2003; Kaplan & McGuckin, 1986; Vernon et al, 2003)
  • Providing automated water/soap sinks appears not to increase hand washing rates compared to traditional non-automated sinks (Larson et al, 1991; 1997)
  • Pittet et al (2000)

They found that a combination of bedside antiseptic hand-rub dispensers and posters to remind staff to clean their hands substantially increased compliance.

  • Muto et al (2000)

They reported that placing alcohol-gel dispensers next to the doors of patient rooms did not increase adherence.

Organizational and technological intervention

  • McGuckin (2006)

The effect of random voice hand hygiene messeages delivered by medical, nursing, and infection control staff on hand hygiene compliance in intensive care

- They found that using random voice message increased handwashing compliance. 
- Twelve voice messages on Handwashing compliance facts 
  such as "hand hygiene should occur before and after patient contact," 
  and so on were installed to deliver prompts to 2 amplified external speakers.
- They measured product usage (soap and sanitizer)and bed-days. 
  During the 6-week baseline period, 18,000 ml soap and 9940 ml 
  sanitizer were used versus 21,000 ml soap and 15,496 ml sanitizer 
  during the intervention.
