- Abstract
Background: The objectives of the study are to investigate the relationship between hand hygiene compliance and hospital-acquired methicillin-resistant Staphylococcus aureus (MRSA) incidence, and to propose a new method for estimating Pearson correlation between pair of rates. Methods: 2011-2014 hand hygiene audit data were linked to hospital-acquired MRSA data in the province of Alberta, Canada. Hand hygiene compliance and hospitalacquired MRSA incidence rates were calculated at the unit, site, zone and provincial levels. Pearson correlation coefficients were calculated for the pairs of the rates. The 95% confidence limits of the Pearson correlation coefficients were estimated based on the information contained in hospital-acquired MRSA incidence rates. Results: Strong longitudinal correlations between hospital-acquired MRSA incidence and hand hygiene compliance were found at the provincial level and for the Calgary Zone and Edmonton Zone (<-0.95). At the site level, a strong correlation was found for the Foothills Medical Centre (-0.88). Conclusion: Combining the traditional Pearson correlation technique with the proposed inference method provides a simple and proper method for detecting the relationship between healthcare-acquired infection and hand hygiene.
