Background:
Despite numerous studies assessing bundled interventions to enhance hand hygiene compliance (HHC), compliance rates persist at suboptimal levels. Our objective was to employ Kotter's Change Model (KCM) to enhance HHC and conduct a comprehensive process evaluation among medical staff within the intensive care unit (ICU).
Methods:
KCM was implemented at the ICU of Zhongnan Hospital of Wuhan University from March 2018 to August 2021, with a 41-month longitudinal monitoring of HHC. The primary outcome focused on the absolute monthly change in HHC. Secondary outcomes encompassed the HHC characteristics across different phases, varying trends in HHC concerning different hand hygiene opportunities and occupations, quarterly incidences of central line-associated bloodstream infections (CLABSI) and catheter-associated urinary tract infections (CAUTI).
Results:
This study included 20,222 hand hygiene actions and 24,195 opportunities. The overall HHC was 83.58 % (95 %CI, 83.11 %-84.04 %). Following the KCM implementation, HHC surged from 35.71 % (95 % CI, 22.99 %-50.83 %) to 87.75 % (95 % CI, 85.53 %-89.67 %), reflecting a notable increase of 145.73 %. The most rapid growth in HHC occurred post-patient contact, elevating from 35.29 % to 89.8 %. Despite escalating patient numbers and treatment complexities annually, the quarterly rates of CLABSI (0 ‰-3.53 ‰) and CAUTI (0.96 ‰-4.26 ‰) remained consistently low.
Conclusion:
Utilizing KCM systematically alters healthcare providers' perception of hand hygiene, fostering an environment that advocates for and sustains improved HHC among ICU personnel.
Implications For Clinical Practice:
The Kotter's change model can be an effective framework for healthcare organizations to systematically improve and maintain hand hygiene compliance among healthcare providers, which can in turn help reduce healthcare-associated infections.
