Author, journal, date | Type of studies included | Population | Type of intervention | Major conclusion |
|---|---|---|---|---|
Azarpazhooh A. et al., J Periodontol, 2006 [37] | Systematic Review (7 RCT, 3 control trials) | Elderly adults living in nursing homes, ICU patients and patients from a general hospital | Professional dental care, mouthrinse with 0.12 % CHX, application of 0.2% CHX gel, 1% PVI scrubbing of pharynx, topical application of a non-absorbable antibiotic solution and topical antimicrobial prophylaxis | Oral care reduces incidence of pneumonia |
Sjorgen P. et al., J Am Geriatr Soc, 2008 [36] | Systematic Review (5 RCT, 1 systematic review, 3 case–control trials, 5 cross-sectional trials, 1 retrospective trial) | Dependent elderly people | 0.12% CHX oral rinse, tooth-brushing, 1% PVI scrubbing of pharynx or professional mechanical oral health care weekly | Oral care prevents pneumonia, respiratory tract infection and death from pneumonia |
Kaneoka A. et al., Infect Control Hosp Epidemiol, 2015 [34] | Systematic Review (4 RCT) and Meta-analysis (5 RCT) | Hospitalized non-ventilated patients and patients living in nursing homes | 0.2% CHX application, 0.12% CHX gargle, tooth brushing performed by dental professionals, ± 1% PVI scrubbing of pharynx | Oral care prevents pneumonia and fatal pneumonia in non-ventilated patients |
El-Rabbany M. et al., Int J Nurs Stud, 2015 [35] | Systematic Review (28 RCT) | Elderly adults living in nursing homes and ICU patients | Professional dental care, sodium bicarbonate mouthrinse, toothbrushing, 0.12% and 0.2% CHX, topical application of a non-absorbable antibiotic solution and PVI swab | Oral care was suggested to be associated with a reduction in the risk for HAP and VAP in high-risk patients |
