Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Based on the poor situation of residents in German nursing homes with regard to oral health, a cluster-randomized Trial will be carried out in Rhineland-Palatindate, Germany. Dentists investigated residents to identify dental or oral hygiene problems. In the invention group, dentists' recommendations will be reinstructed to the nursing staff by dental assistance.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Introduction: Oral health and oral-health-associated quality-of-life (OHrQL) of residents in German nursing homes are poor. The investigators will develop an evidence-based catalogue of interventions applicable and sustainable ("Oral Health Tool Box"). Based on this, care-accompanying reinstruction and remotivation of nursing staff by dental assistants (DA) will be provided. The investigators hypothesize such complex intervention to significantly improve OHrQL, and daily oral hygiene/care behaviour and its cost-effectiveness.

Methods and analysis: Based on the findings of a rapid systematic review, possible intervention components will be systematized and assessed for their effectiveness. Mixed methods will be used to identify barriers and enablers of oral hygiene and care in German long-term residential care (LRC), and these will be linked with the intervention components using the Theoretical Domains Framework and the Behavior Change Wheel, the result being an "Oral Health Tool Box". A two-arm cluster, randomized-controlled-trial (ratio of 1:1 via block randomization) will be performed in nursing homes in Rhineland-Palatinate, Germany, including residents with moderate to severe care dependency. Each nursing home represents a cluster. Based on a feasibility study, considering clustering and possible attrition, the investigators aim at recruiting 618 residents of 18 cluster. In the intervention group, dentists will identify the specific problems of each resident, and assign one or more intervention components from the box. During follow-up, nursing staff will be reinstructed and remotivated by dental assistants in how to deliver the intervention components in individual intervals. In the control group residents will receive care as usual. The primary outcome, OHrQL, will be measured using the German version of the General Oral Health Assessment Index (GOHAI). Secondary outcomes include pain condition, general health-related quality-of-life, caries increment, oral/prothetic hygiene and gingival status, incidence of dental emergencies and hospitalizations, and cost-utility/effectiveness. The endpoints will be measured at baseline and after 12 months. For the primary outcome, a mixed-linear model will be used within an intention-to-treat analysis. A process evaluation using mixed methods will be conducted alongside the trial.

Due to the pandemic, the number of cases could not be reached despite outstanding commitment in recruitment. An application was made to the funding agency to adapt the project plan.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention group

In the intervention group, a range of clinical parameters are recorded and the dentists prepares an individual oral hygiene and care recommendation, based on the Oral Health Tool Box. The Box is also used for instructing the dental assistants and the nursing staff for each patient individually. It is then determined when and how the dental assistants re-evaluates the oral hygiene and care process and reinstructs and remotivates the nursing staff. If the examination reveals a need for dental treatment (possibly requiring referral and transport), this will be communicated to the nursing staff. The dental assistant will further receive a training in communication, enabling them in reinstruction and remotivation. Dentists and dental assistants will further receive a training in geriatric dentistry by the State Commissioner of the German Society for Geriatric Dentistry.

Control group

In the control group, the residents receive care as usual. This includes the recording of the same parameters are recorded as in intervention group, a standardized form is filled out and handed over to the nursing staff. As in the case of Intervention group, the nursing staff is informed in the event of a need for treatment. No further measures are applied.
