The document discusses quality improvement for reducing diarrhea cases through a handwashing program. It proposes using the FADE model and microsystems approach to design the program. Measurement tools would quantitatively and qualitatively assess handwashing rates, diarrhea incidence, and impact. Ethical considerations include informed consent, confidentiality, and balancing risk of spreading infection against the duty to protect patients. Overall the program aims to determine if handwashing increases and diarrhea cases decrease.
