Design outcomes

Primary

MeasureTime frame
Feasibility outcome: Recruitment and set-up of sites within 6 months of study start measured as confirmation of Capacity & Capability (C&C) from each site

Secondary

MeasureTime frame
1. Implementation of staff education and training at all four participating sites within 3 months of trial start date measured using Theoretical Domains Framework (TDF) to identify barriers and facilitators to implementation of the OHC interventions. 2. Recruitment of participants to work stream 1 (feasibility) within 15 months of trial start date measured as monthly recruitment of 8 participants 3. Retention of consented participants measured as those receiving allocated oral healthcare (OHC) intervention until discharge/repatriation from participating site for a maximum of 3 months from date of stroke symptom-onset and by completion of follow-up (by telephone or face-toface) at 3 months from date of stroke symptom-onset 4. Adherence to allocated OHC treatment measured as those receiving allocated OHC intervention twice-daily until discharge/repatriation from participating site for a maximum of 3 months from date of stroke symptom-onset 5. Measured weekly from 14 days from stroke-onset to maximum 3 months and discharge: 5.1. Swallow status will be measured weekly from 14 days from stroke-onset to maximum 3 months and discharge by capturing the result of any clinical Speech & Language Therapy (SLT) or bedside swallow assessment 5.2. Incident pneumonia based on CDC criteria 5.3. Oral health measured using the Geriatric Oral Health Assessment Index (GOHAI) 6. Condition of the oral cavity will be measured using THROAT score at 7-10 days from stroke-onset 7. Adverse events measured using patient records at 7-10 days from stroke-onset 8. Disability measured using the modified Rankin Scale score at 3 months from stroke-onset
