Long-term effectiveness of the midwifery initiated oral health-dental service program on maternal oral health knowledge, preventative dental behaviours and the oral health status of children in Australia.

BACKGROUND: The Midwifery Initiated Oral Health-Dental Service was developed to train midwives to promote maternal oral health, and a large trial showed it substantially improved the oral health, knowledge and behaviours of pregnant women. AIM: Evaluate the long-term effectiveness of the program (post-trial) on maternal oral health knowledge, dental behaviours, and early childhood caries in offspring. METHODS: A prospective cohort study involving 204 women and children 3-4 years (followed after trial) was conducted in Sydney, Australia from 2017 to 2019. RESULTS: The program did not have a significant impact on the study measures. Mothers who received the program did have comparatively better knowledge around preventative behaviours to reduce early childhood caries and significantly more mothers were engaging in a key behaviour of using a cup to feed their child. Overall maternal oral health knowledge and level of education did have a protective effect on the dental decay of children. Higher knowledge and levels of education reduced the odds of having a dmft of one or more by over half (OR 0.473), and almost 80% (OR 0.212) respectively. CONCLUSIONS: Although the MIOH-DS program was not effective, there is still value in exploring other complementary interventions to improve maternal oral health, especially for disadvantaged families. Future research should focus on co-designing an antenatal and postnatal oral health intervention and exploring its long-term impact on the oral health of children.

Economic evaluation of the Midwifery Initiated Oral Health-Dental Service programme in Australia.

OBJECTIVES: To critically evaluate the cost-effectiveness of the Midwifery Initiated Oral Health-Dental Service (MIOH-DS) designed to improve oral health of pregnant Australian women. Previous efficacy and process evaluations of MIOH-DS showed positive outcomes and improvements across various measures. DESIGN AND SETTING: The evaluation used a cost-utility model based on the initial study design of the MIOH-DS trial in Sydney, Australia from the perspective of public healthcare provider for a duration of 3 months to 4 years. PARTICIPANTS: Data were sourced from pregnant women (n=638), midwives (n=17) and dentists (n=3) involved in the MIOH trial and long-term follow-up. COST MEASURES: Data included in analysis were the cost of the time required by midwives and dentists to deliver the intervention and the cost of dental treatment provided. Costs were measured using data on utilisation and unit price of intervention components and obtained from a micro-costing approach. OUTCOME MEASURES: Utility was measured as the number of Disability Adjusted Life Years (DALYs) from health-benefit components of the intervention. Three cost-effectiveness analyses were undertaken using different comparators, thresholds and time scenarios. RESULTS: Compared with current practice, midwives only intervention meets the Australian threshold (A$50 000) of being cost-effective. The midwives and accessible/affordable dentists joint intervention was only 'cost-effective' in 6 months or beyond scenarios. When the midwife only intervention is the comparator, the midwife/dentist programme was 'cost-effective' in all scenarios except at 3 months scenario. CONCLUSIONS: The midwives' only intervention providing oral health education, assessment and referral to existing dental services was cost-effective, and represents a low cost intervention. Midwives' and dentists' combined interventions were cost-effective when the benefits were considered over longer periods. The findings highlight short and long term economic benefits of the programme and support the need for policymakers to consider adding an oral health component into antenatal care Australia wide.

Process evaluation of the midwifery initiated oral health-dental service program: Perceptions of dental professionals.

ISSUE ADDRESSED: All pregnant women should have a comprehensive oral health evaluation. Unfortunately, many pregnant women seldom seek dental care and some dentists are hesitant to treat during pregnancy. To address these issues, the Midwifery Initiated Oral Health Dental Service (MIOH-DS) program was developed in Australia. The aim of this study was to undertake a process evaluation and explore the perceptions of dental professionals involved in the program to determine the acceptability, feasibility and effectiveness of the program if it were to be upscaled. METHODS: A qualitative approach using content analysis was conducted on data from two focus groups involving 12 dental professionals. RESULTS: All participants were supportive of the MIOH-DS program. They thought pregnant women were receptive to their care, and reported markedly improved oral health. The provision of free dental care and the involvement of midwives were cited as major factors that improved the uptake of the program. Some of the challenges encountered were the prevailing misconceptions about the safety of dental treatment and pregnancy-related impairments. CONCLUSIONS: Dental professionals found the MIOH-DS to be acceptable, feasible and effective in improving oral health of pregnant women and their uptake of dental services. However, some challenges need to be addressed as the MIOH-DS program is upscaled into a cost-effective model. SO WHAT?: Dental professionals are important stakeholders in the MIOH-DS model. The process evaluation of the successful dental intervention is necessary to understand how and why such interventions work, and is an important step in scaling up to a population-wide intervention.

Process evaluation of the midwifery initiated oral health-dental service program: Perceptions of midwives in Greater Western Sydney, Australia.

BACKGROUND: Despite links between poor maternal oral health, adverse pregnancy outcomes and early childhood decay there is limited emphasis on maternal oral health in Australia. To address this, the Midwifery Initiated Oral Health Dental Service (MIOH-DS) program was developed in collaboration with the Australian College of Midwives. AIMS: To undertake a process evaluation and explore perceptions of midwives involved in the MIOH-DS program to determine its practicability, acceptability and feasibility if it were to be up-scaled and implemented into clinical practice. METHODS: Qualitative content analysis was undertaken on data from three focus groups with 21 midwives. FINDINGS: Midwives generally found the MIOH-DS to be acceptable and feasible with potential for widespread scalability. The trust women had in midwives was an important factor in gaining women's attention about oral health in pregnancy. The program assisted in increasing midwives' knowledge and awareness, though some felt it was outside their scope of practice. The oral health assessment tool was acceptable to midwives but some concerns were expressed about undertaking a visual oral inspection. Most midwives stated they were now confident with referring individuals to a dentist. Significant barriers to widespread implementation included the cost of dental care and the continued lack of awareness and misconceptions pregnant women had towards oral health. CONCLUSION: Midwives found the MIOH-DS to be acceptable and feasible which are two important barriers to potential implementation at scale. Misconceptions over the importance of oral health by women and cost of accessing dental services still need resolving.
