Input: We included three studies involving 470 participants. These trials were of limited comparability evaluating an OHC education training programme, a decontamination gel and a ventilator-associated pneumonia bundle of care augmented with an OHC component by comparing them to a deferred intervention, a placebo gel or standard care respectively. The OHC educational intervention demonstrated a significant reduction in denture plaque scores up to six months (P < 0.00001) after the intervention but not dental plaque. Staff knowledge (P = 0.0008) and attitudes (P = 0.0001) towards oral care also improved. The decontamination gel reduced the incidence of pneumonia amongst the intervention group (P = 0.03). Based on two trials involving a small number of stroke survivors, OHC interventions can improve staff knowledge and attitudes, the cleanliness of patients' dentures and reduce the incidence of pneumonia. Improvements in the cleanliness of patients teeth were not observed. Further evidence relating to staff-led oral care interventions is severely lacking.
Output:

This review of three studies involving 470 participants found little evidence of how this care is best delivered. Information on a small number of nursing home residents who had a stroke (67 participants from a larger trial) showed that training nursing staff improved their knowledge of oral care and resulted in improved oral hygiene in their patients. Another trial demonstrated the beneficial impact of a decontamination gel on the incidence of pneumonia amongst patients in a stroke ward. However, there was no other information on how best to provide oral hygiene and more studies are urgently needed.
