Oral health self-care behaviours in serious mental illness: A systematic review and meta-analysis

Decreased oral function in Japanese inpatients with schizophrenia

AIM

Oral function in patients with schizophrenia has not been well-characterized. To address this, we performed a cross-sectional study of oral function in Japanese inpatients with schizophrenia.

METHODS

We measured oral function, including occlusal force, tongue-lip motor function, tongue pressure, and masticatory function in 130 Japanese inpatients with schizophrenia. We then compared the frequency of clinical signs of oral hypofunction among 63 non-elderly and 67 elderly inpatients with schizophrenia, as well as data from 98 elderly control participants from a previous Japanese study.

RESULTS

The frequency of reduced occlusal force was significantly higher in the elderly inpatients (76.2%) than in the non-elderly inpatients (43.9%) and elderly controls (43.9%). The frequency of decreased tongue-lip motor function in non-elderly inpatients (96.8%) and elderly inpatients (97.0%) was significantly higher than that in elderly controls (56.1%). The frequency of decreased tongue pressure in non-elderly inpatients (66.1%) and elderly inpatients (80.7%) was significantly higher than that in elderly controls (43.9%). Finally, the frequency of decreased masticatory function was highest in elderly inpatients (76.5%), followed by non-elderly inpatients (54.8%) and elderly controls (15.3%).

CONCLUSION

Oral function was decreased in both non-elderly and elderly Japanese inpatients with schizophrenia compared with elderly controls.

Periodontal disease in people with a history of psychosis: Results from the UK biobank population-based study

OBJECTIVES

To test the hypotheses that: (1) Prevalence of periodontal disease would be higher in people with a history of psychosis when compared to the general population and (2) Demographic, life-style related factors and co-morbid medical conditions would predict periodontal disease in people experiencing psychosis.

METHODS

The authors performed cross-sectional analysis of baseline data from the UK Biobank study (2007-2010), identifying cases with psychosis using clinical diagnosis, antipsychotic medication, and self-report. Demographic (age, gender, ethnicity, socioeconomic status), lifestyle-related(BMI, blood pressure, smoking and alcohol intake, physical activity) and physical co-morbidities (cancer, cardiovascular, respiratory, inflammatory disease and metabolic conditions) were included as potential risk factors for periodontal disease among people with a history of psychosis using logistic regression analyses. The analysis sample included 502,505 participants.

RESULTS

Risk of periodontal disease was higher in people with psychosis, regardless of how cases were identified. Patients with a clinical diagnosis had the highest proportion of periodontal disease compared to the general population (21.3% vs. 14.8%, prevalence ratio 1.40, 95% CI: 1.26-1.56). Older and female cases were more likely to experience periodontal disease. Lifestyle factors (smoking) and comorbidities (cardiovascular, cancer or respiratory disease) were associated with periodontal disease among people with a history of psychosis.

CONCLUSIONS

The findings suggest that periodontal disease is more common in people with a history of psychosis, compared to the general population. Prevention and early diagnosis of periodontal disease should be a priority for oral health promotion programmes, which should also address modifiable risk factors like smoking which also contribute to co-morbid systemic disease.

A two-arm, randomised feasibility trial using link workers to improve dental visiting in people with severe mental illness: a protocol paper

BACKGROUND

People with severe mental illness (e.g. psychosis, bipolar disorder) experience poor oral health compared to the general population as shown by more decayed, missing and filled teeth and a higher prevalence of periodontal disease. Attending dental services allows treatment of oral health problems and support for prevention. However, people with severe mental illness face multiple barriers to attending routine dental appointments and often struggle to access care. Link work interventions use non-clinical support staff to afford vulnerable populations the capacity, opportunity, and motivation to navigate use of services. The authors have co-developed with service users a link work intervention for supporting people with severe mental illness to access routine dental appointments. The Mouth Matters in Mental Health Study aims to explore the feasibility and acceptability of this intervention within the context of a feasibility randomised controlled trial (RCT) measuring outcomes related to the recruitment of participants, completion of assessments, and adherence to the intervention. The trial will closely monitor the safety of the intervention and trial procedures.

METHODS

A feasibility RCT with 1:1 allocation to two arms: treatment as usual (control) or treatment as usual plus a link work intervention (treatment). The intervention consists of six sessions with a link worker over 9 months. Participants will be adults with severe mental illness receiving clinical input from secondary care mental health service and who have not attended a planned dental appointment in the past 3 years. Assessments will take place at baseline and after 9 months. The target recruitment total is 84 participants from across three NHS Trusts. A subset of participants and key stakeholders will complete qualitative interviews to explore the acceptability of the intervention and trial procedures.

DISCUSSION

The link work intervention aims to improve dental access and reduce oral health inequalities in people with severe mental illness. There is a dearth of research relating to interventions that attempt to improve oral health outcomes in people with mental illness and the collected feasibility data will offer insights into this important area.

TRIAL REGISTRATION

The trial was preregistered on ISRCTN (ISRCTN13650779) and ClinicalTrials.gov (NCT05545228).

Nurse-Led Physical Health Interventions for People with Mental Illness: A Scoping Review of International Literature

People with mental illness have a higher prevalence of co-occurring physical health conditions and poor health behaviors, leading a mortality gap of up to 16 years, compared with the general population. Nurses working in mental health settings play an important role in addressing factors influencing sub-optimal physical health. Therefore, this scoping review aimed to identify nurse-led physical health interventions and align interventions to eight recognized physical healthcare priority areas (i.e. Equally Well in Victoria Framework). A systematic search strategy was used to identify relevant literature. Data extraction included alignment to the Equally Well priority areas, research design, and indication of co-design (meaningful and collaborative involvement of consumers and significant others) and recovery-oriented practice (focusing on needs and goals of a consumer's recovery journey). All included papers (n = 74) were aligned to at least one of eight Equally Well priority areas. Papers were predominately quantitative (n = 64, 86%), with the remainder mixed methods (n = 9, 9%) or qualitative (n = 4, 5%). Most papers were aligned to improving metabolic health and support to quit smoking. One study focused on nurse-led intervention designed to reduce falls. Recovery-oriented practice was evident in six papers. No paper described evidence of co-design. A research gap was identified for nurse-led intervention to reduce falls and improve dental/oral care. Relative to mental healthcare policy, there is a need for future nurse-led physical health research to be co-designed and include recovery-oriented practice. Evaluation and description of future nurse-led physical interventions should seek to report perspectives of key stakeholders as these remain relatively unknown.

Mental Disorders and Oral Diseases: Future Research Directions

The poor physical health (including oral health) of people with mental disorders is a global problem. The burden of oral diseases among this group is substantial given their high prevalence and ability to increase the personal, social, and economic impacts of mental disorders. This article summarizes causes of mental disorders and oral diseases, critically reviews current evidence on interventions to reduce the burden of oral diseases in people with mental disorders, and suggests future research directions. The relationship between mental disorders and oral diseases is complex due to the shared social determinants and bidirectional interaction mechanisms that involve interconnected social, psychological, behavioral, and biological processes. Research has, to date, failed to produce effective and scalable interventions to tackle the burden of oral diseases among people with mental disorders. Transformative research and actions informed by a dynamic involvement of biological, behavioral, and social sciences are needed to understand and tackle the complex relationship between mental disorders and oral diseases, as well as inform the design of complex interventions. Examples of future research on complex public health, health service, and social care interventions are provided. The design and testing of these interventions should be carried out in real-world settings, underpinned by the principles of coproduction and systems thinking, and conducted by a transdisciplinary team. We propose this starts with setting research priorities and developing complex intervention theory, which we report to support future research to improve oral health and hence physical and mental health in this disadvantaged group.

A Qualitative Study Exploring the Barriers and Facilitators for Maintaining Oral Health and Using Dental Service in People with Severe Mental Illness: Perspectives from Service Users and Service Providers

People with severe mental illness suffer from a high burden of oral diseases, which can negatively impact their physical and mental well-being. Despite the high burden, they are less likely to engage in oral health care including accessing dental services. We aimed to identify both the service users' and service providers' perspective on the barriers and facilitators for maintaining oral health and dental service use in people with severe mental illness. Qualitative exploration was undertaken using dyadic or one-to-one in-depth interviews with service users in the UK with a diagnosis of schizophrenia, schizoaffective disorder or bipolar disorder. Service providers, including mental health and dental health professionals, and informal carers (people identified as family or friend who are not paid carers) were also interviewed. Thematic analysis of the data revealed three main cross-cutting themes at the personal, inter-personal and systems level: amelioration of the problem, using a tailored approach and provision of comprehensive support. The main barriers identified were impact of mental ill-health, lack of patient involvement and tailored approach, and accessibility and availability of dental services including lack of integration of services. The main facilitators identified were service providers' effective communication skills and further support through the involvement of carers. The findings suggest that the integration of dental and mental health services to provide tailored support for overall health and well-being, including the oral health of the patient, can better support people with severe mental illness regarding their oral health needs.
