Does the presence of oral health teams influence the incidence of ventilator-associated pneumonia and mortality of patients in intensive care units? Systematic review
Abstract
AIMS
To verify whether oral health teams influence the oral health status, ventilator-associated pneumonia incidence and mortality rate of patients in Intensive Care Units (ICU).
MATERIALS AND METHODS
Bibliographic searches were performed in PubMed, Scopus, Web of Science, Lilacs, Embase, Livivo, Open Grey, Academic Google, and Cochrane databases. The assessment of the methodological quality and risk of bias of the included studies and a random-effects meta-analysis to summarize relative risk data for ventilator-associated pneumonia (VAP) and mortality were performed. An analysis of the certainty of the evidence was performed for the main outcomes analyzed.
RESULTS
Records of 518 studies were analyzed by reading titles and abstracts. Five studies were included according to eligibility criteria. The meta-analysis showed that ICU patients undergoing dental care by an oral health team had a lower incidence of VAP (OR = 0.33; 95% CI: 014-0.76) but did not lower mortality rates (OR = 0.46 95% CI: 0.16-1.32). The certainty of the evidence was considered very low.
CONCLUSION
Dental care provided by oral health teams in a hospital environment did not influence oral health status or mortality, although it contributed to a reduction in VAP of patients admitted to the ICU.
How strong is the evidence?
Evidence Hub reads this as a systematic review, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid.
