Detailed Description
Pneumonia complicating stroke is very difficult to manage and has a very poor prognosis, leading to a significantly higher risk of death.
Oral opportunistic pathogens have been reported to be associated with the incidence of pneumonia among non-stroke immunocompromised subjects.
Preliminary studies found that patients with stroke had higher carriage rates of oral opportunistic pathogens than healthy subjects.
Therefore, investigators hypothesize that pneumonia complicating stroke is associated with oral opportunistic pathogens, and oral health promotion interventions may reduce the incidence of pneumonia complicating stroke via its effects on the species and relative abundance of oral opportunistic pathogens.
In order to prove this, investigators need to (1) firstly conduct a randomized controlled trial to confirm whether oral health promotion is able to reduce the levels of plaque, and the incidence of pneumonia complicating stroke at clinical level; (2) secondly employ metagenomics analysis to compare oral rinse samples and respiratory samples, and to identify pneumonia-associated "oral opportunistic pathogens group"; (3) finally elucidate how oral health promotion influences the species and relative abundance of oral opportunistic pathogens.
This proposed study will provide evidence for the integration of oral health promotion as part of interdisciplinary stroke rehabilitation.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Advanced oral hygiene care programme
Patients with stroke will receive the advanced oral hygiene care programme (AOHCP) comprising powered tooth brushing and mouth rinsing with chlorhexidine (with a supply of standardized power tooth brushes, mouth rinse, tooth paste and oral hygiene instruction).
|
|
EXPERIMENTAL: Oral hygiene instruction
Patients with stroke will only receive the oral hygiene instruction.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The prevalence of pneumonia complicating stroke
Time Frame: 1 week
|
To calculate and compare the incidence of pneumonia between interventional group and control group, to identify whether the intervention approach could reduce the short-term incidence after the baseline.
|
1 week
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The prevalence of pneumonia complicating stroke
Time Frame: 1 month, 3 months, 6 months
|
To calculate and compare the long-term incidence of pneumonia between interventional group and control group.
|
1 month, 3 months, 6 months
|
Metagenomic
Time Frame: 3 days, 5 days, 7 days, and 1 month, 3 months, 6 months
|
To analyze composition and relative abundance of oral microbiome in oral rinse samples.
|
3 days, 5 days, 7 days, and 1 month, 3 months, 6 months
|
Plaque Index
Time Frame: 1 month, 3 months, 6 months
|
0 = no plaque detected with probe; 1 = plaque not visible by unaided eye but detectable with probe; 2 = moderate amount of plaque; 3 = abundance of plaque
|
1 month, 3 months, 6 months
|
Gingival Bleeding Index
Time Frame: 1 month, 3 months, 6 months
|
0 = no bleeding after probing; 1 = presence of bleeding within 10 seconds after probing.
|
1 month, 3 months, 6 months
|
the Short Form Health Survey 12 (SF-12)
Time Frame: 1 month, 3 months, 6 months
|
The SF-12 consists of 12 items covering eight conceptual domains of health: general health (GH), physical functioning (PF), bodily pain (BP), role-physical (RP), mental health (MH), vitality (VT), social functioning (SF), and role-emotional (RE).
Four items are reversed for scoring (item no.: 1, 8, 9, and 10).
The SF-12 consists of 12 items and each of them has its own physical component summary (PCS) and mental component summary (MCS) regression coefficients.
The response to each item will be multiplied by its PCS regression coefficient and added together with the PCS constant to provide Physical Health summary scores (SF-12 PCS).
Mental Health summary scores (SF-12 MCS) will be calculated likewise.
A higher scores mean a better outcome.
|
1 month, 3 months, 6 months
|
the Oral Health Impact Profile 14 (OHIP-14)
Time Frame: 1 month, 3 months, 6 months
|
0=never, 1=hardly ever, 2=occasionally, 3=fairly often, and 4=very often/all of the time.
Summary OHIP-14 score and domain scores will be derived by summating responses to each item (i.e.
score 2, 3, and 4).
A higher scores mean a worse outcome.
|
1 month, 3 months, 6 months
|
the Geriatric Oral Health Assessment Index (GOHAI)
Time Frame: 1 month, 3 months, 6 months
|
1 = always, 2 = often, 3 = sometimes, 4 = seldom, and 5= never.
Summary GOHAI scores will be derived by summating responses to items after reversing the coding of the three positively worded items (swallowing, appearance, and discomfort when eating).
A higher scores mean a better outcome.
