The impact of workload on hygiene compliance in nursing.

The objective of this research was to clarify whether external factors (e.g. ward capacity, level of nursing intensity) had an influence on nursing staff compliance with hand hygiene guidelines. The study was conducted at a German hospital (450 beds). Quantitative data were collected prospectively in six trial phases (E1-E6) starting in June 2007 and ending in May 2008. Included in the study were ten hospital departments: four surgical wards, four internal medicine departments, and two interdisciplinary intensive care units. In six participant observation trials, nursing staff were monitored for the disinfection of hands. Narrative interviews were conducted immediately after the observation with those who did not disinfect their hands in accordance with national guidelines. Observations and interviews were unannounced, taking place at different times. The collected data was analysed on subsequent categorization after summarizing the core statements (content analysis). The statistical relevance of staff compliance to the rate of used ward capacity could be proved using a multifactorial regression model (P=0.011). Workload factors (e.g. maximum ward capacity, severity of patient cases) have an impact on staff compliance with hand hygiene guidelines, even where non-compliance contradicts the personal level of professional training.
