This assignment analyzes a nursing research study investigating the impact of a new hand hygiene protocol on reducing hospital-acquired infections (HAIs) among critically ill patients in an ICU setting. The study employed a pre-experimental design with a quantitative approach, utilizing data collected through interviews and statistical analysis to assess the effectiveness of the intervention. The researchers found that the new protocol significantly improved hand-washing compliance among nurses, leading to a reduction in HAIs. This study provides valuable evidence for nursing practice and highlights the importance of implementing effective infection control measures.
