Effectiveness of hand hygiene promotional program based on the WHO multimodal hand hygiene improvement strategy, in terms of compliance and decontamination efficacy in an indian tertiary level neonatal surgical intensive care unit

摘要

abstract_textpBackground: The WHO Multimodal Hand Hygiene Improvement Strategy (MHHIS) has been proposed to improve the Hand Hygiene (HH) compliance of the WHO recommendations on HH.Therefore, the current study was planned in our neonatal unit with the objective of evaluating the effectiveness of a Hand Hygiene Promotional Program (HHPP) based on the WHO MHHIS, in terms of compliance and decontamination efficacy among the health-care workers (HCWs) in the unit. Objective: The objective of the study was to evaluate the effectiveness of the WHO MHHIS on HH compliance and decontamination efficacy. Methods: The HHPP was carried out in our neonatal surgical intensive care unit from July to August 2013. A pre-intervention phase consisted of assessment of ward infrastructure, HH knowledge and perception, determination of HH compliance and collection of hand rinse samples from the HCWs before and after handwashing. Intervention phase consisted of changing traditional to elbow-operated taps, display of posters and reminders, placement of soaps in water draining trays, autoclaved single-use paper towels for hand drying, availability of hand rubs and training sessions for health-care providers. In the post-intervention phase, all the assessments and observations of pre-intervention phase were repeated. Results: HHPP resulted in a significant increase in overall HH compliance from 26.6 (95 confidence interval CI 23.9-29.3) to 65.3 (95 CI 62.4-68.2) (P 0.001) and reduction in load of microorganisms (P = 0.013). There was a significant improvement in HH knowledge (P 0.001), and perception surveys revealed high appreciation of each strategy component by the participants. Conclusion: To the best of our knowledge, this is the first study about the effect of implementation of the WHO MHHIS from an Indian hospital. HHPP was found to be effective in terms of HH compliance and decontamination efficacy. Its implementation is highly recommended to promote HH in a developing country like India./p/abstract_text
