Perspectives and experiences of Thai adults using wheelchairs regarding barriers of access to dental services: a mixed methods study

Effectiveness of an individually tailored oral hygiene intervention in improving gingival health among community-dwelling adults with physical disabilities in Thailand

AIMS

Persons with physical disabilities require specific methods for sustaining good oral health. This study aimed to evaluate an individually tailored oral hygiene intervention program (IT-OHI) for improving gingival health among adults with disabilities.

METHODS AND RESULTS

A single group, quasi-experimental design with pre- and post-tests, conducted at a community club for disabled people in Thailand. This study included 145 adults with disabilities, aged 18-74 years. Trained caregivers provided IT-OHI program to all participants. Calibrated dentists assessed the gingival bleeding and dental plaque at baseline/pre-intervention (T0) and at 6 (T1) and 12 (T2) weeks post-intervention. The outcomes were analyzed using the Friedman test, Cochran's Q test, and Binary logistic regression. There were significant decreases in bleeding on probing scores (P < .001) and plaque control record scores (P < .001) throughout the study. However, considering the individual periods, values between T1 and T2 did not improve. Additionally, the IT-OHI program's protective effect was more substantial among the male participants at 12 weeks post-intervention (odds ratio = 0.094, P = .027) than among the females.

CONCLUSION

The IT-OHI program had partial effectiveness in improving gingival health and reducing dental plaque accumulation in a group of Thai people with physical disabilities; however, the long-term impact remains unclear.

Barriers to accessing primary healthcare services for people with disabilities in low and middle-income countries, a Meta-synthesis of qualitative studies

METHODS

Six electronic databases were searched for relevant studies from 2000 to 2019. Forty-one eligible studies were identified.

RESULTS

Findings suggest that the people with disabilities' choice to seek healthcare services or not, as well as the quality of intervention provided by primary healthcare providers, are influenced by three types of barriers: cultural beliefs or attitudinal barriers, informational barriers, and practical or logistical barriers.

CONCLUSION

In order to achieve full health coverage at acceptable quality for people with disabilities, it is necessary not only to consider the different barriers, but also their combined effect on people with disabilities and their households. It is only then that more nuanced and effective interventions to improve access to primary healthcare, systematically addressing barriers, can be designed and implemented.IMPLICATIONS FOR REHABILITATIONPeople with disabilities in both high income and low- and middle-income country settings are more likely to experience poorer general health than people without disabilities.Barriers to accessing primary healthcare services for people with disabilities result from a complex and dynamic interacting system between attitudinal and belief system barriers, informational barriers, and practical and logistical barriers.Given primary healthcare is often the initial point of contact for referral to specialty care and rehabilitation services, it is crucial for people with disabilities to access primary healthcare services in order to get appropriate referrals for such services, specifically rehabilitation as appropriate.To achieve full health coverage at acceptable quality for people with disabilities, starting with primary healthcare, it is necessary for healthcare stakeholders, including rehabilitation professionals, to consider the combined and cumulative effects of the various barriers to healthcare on people with disabilities and their families and develop an understanding of how healthcare decisions are made by people with disabilities at the personal and the household level.

Validation of Thai version of the Health Literacy in Dentistry scale: Validation among Thai adults with physical disabilities

AIM

To validate the Thai version of the Health Literacy in Dentistry scale (HeLD-Th) among Thai adults with physical disabilities.

METHODS

The original Health Literacy in Dentistry (HeLD) was translated into Thai (HeLD-Th). The final version of the HeLD-Th was evaluated through a cross-sectional study of 160 participants in Thailand. Interview questionnaires and oral examination were performed. The reliability and validity of the HeLD-Th were determined.

RESULTS

The internal consistency was acceptable, with an overall Cronbach's alpha of 0.76. The face and content validity were confirmed. Sufficient construct validity was revealed by exploratory factor analysis. The convergent validity (P ≤ .013) and discriminant validity (P = .017) were estimated. The concurrent validity and predictive validity were confirmed by significantly higher HeLD-Th scores (P < .001). Multiple linear regression analyses indicated that approximately 60% of the variation in the HeLD-Th scores was explained by the final model.

CONCLUSION

The HeLD-Th has sufficient psychometric properties to assess the oral health literacy of Thai adults with mild to moderate disabilities. There are some limitations of the study due to the small sample size, and the results are specific to Thai adults with disabilities. Future studies using the HeLD-Th scale are recommended.
