The Mouth Matters in Mental Health Study

Mental Disorders, Severe Clinical Trial

Official title: A Randomised Feasibility Trial of an Intervention Using Mental Health Support Workers as Link Workers to Improve Dental Visiting in People With Severe Mental Illness: The Mouth in Mind Study

Status Active, not recruiting

Clinical Trial Summary

To investigate the feasibility and acceptability of a link work intervention to increase planned dental care visits for patients with severe mental illness, and through this to improve their oral health.

1. To understand what constitutes best practice when delivering link work around dental visiting.

2. To identify what training needs exist for support workers around link work.

3. To determine whether patients with SMI are willing to be randomised to a trial targeting dental visiting.

4. To understand whether it is feasible to collect clinical outcome and planned dental appointment data in this population.

5. To explore if, and how, patients with severe mental illness engage with a link work intervention.

6. To understand the potential factors impacting (e.g. facilitators and barriers) acceptability and delivery.

Clinical Trial Description

Background and study aims

Severe mental ill health (SMI) affects around 1% of the population. It includes depression, psychosis, and bipolar disorder. People with experience of SMI are more likely to have problems with their teeth and gums. This includes more missing, filled, and decayed teeth than people without SMI. Having poor oral health can impact a lot of everyday activities like eating, speaking and smiling. It can affect how patients see themselves and their mental health.

Dentists can treat many early teeth and gum problems. However, very few people with SMI attend regular dental appointments. Instead, they are more likely to seek help when in crisis and invasive treatments are the only option. Accessing a dentist for people with SMI can be difficult for lots of reasons. People can feel helpless, fearful, or unmotivated to attend. They can have difficulty booking, planning, and getting to appointments. They may struggle to pay for or access free dental care. Unfortunately, existing dental initiatives have not addressed the barriers facing this group. They do not help people with SMI to attend the dentist.

The investigators want to help people with SMI to access dental care. The study will use mental health support workers who are already working in the National Health Service (NHS). They will link people receiving care from mental health teams with dental services. The support workers will help people to book, plan, and attend regular dental appointments. They will support patients to apply for financial support. People call this type of support link work. Research has indicated that link work can increase dental visits in people who might not normally attend. Mental health support workers already do link work for other appointments. Link work has been used to help other vulnerable groups of people (e.g. children) around dental care. However, this will be the first use of link work to help people with SMI to attend the dentist.

Who can participate?

People with a severe mental health difficulties currently accessing secondary care mental health services at the point of referral (e.g. community mental health team, early intervention for psychosis service), but who have not had a routine dental appointment in the past three years.

What does the study involve?

Participants will be randomly allocated to receiving treatment as usual or treatment as usual plus the link work intervention. This will be decided by chance. The investigators will measure how often people in both groups visit the dentist. They will also assess the state of their teeth and gums. They will collect this data when people come into the study and after nine months. The authors will offer interviews to patients and staff involved in the trial to understand how they found their involvement.

What are the possible benefits and risks of participating?

The intervention aims to support people to access dental services. However, it is currently untested, which is the reason for doing the research.

When is the study starting and how long it is expected to run for?

Recruitment for the trial is starting in September 2022 and will run for seven months. The whole project is scheduled to finish in April 2024.

Who is funding the study?

The National Institute of Health Research (NIHR) Health and Social Care Delivery Research (HS&DR) scheme are funding the project. ;
