Health Literacy Impact on Patient-Provider Interactions Involving the Treatment of Dental Problems

Exploring associations between oral health measures and oral health-impacted daily performances in 12–14-year-old schoolchildren

Background

Oral health-related quality of life, a prominent topic in dentistry, has been studied extensively. However, the comparison between various self-perceived and clinical oral health measures still needs to be explored. The purpose of the current study is; first, to report the self-perceived and clinically examined oral health measures that are associated with the oral impacts on daily performances. Second, to identify the oral health measure that best predicts greater oral impact scores. Third, to investigate the difference in findings related to the disease experience measures and the treatment measures.

Methods

A cross-sectional study was carried out on children aged 12–14 years. The prevalence, frequency, and oral impact scores of each daily performance were calculated. Thirteen self-perceived OH conditions were assessed. Clinically examined oral health measures included gingival health, oral hygiene status, DMFT, DT, MT, and FT scores and, one or more decay (1 + D), missing (1 + M) and filled (1 + F) teeth. Simple linear and multiple linear regressions were carried out to report the associations.

Results

At least one oral health impacted daily performance was reported by 40% of the total sample of schoolchildren (N = 700). Based on the magnitude and precision of adjusted regression coefficients (RC), decay severity (DT) was identified as a better predictor of a greater oral impact score with regression coefficient values ranging between 0.3 (social contact) and 2.4 (1 + performance). Contrariwise, MT and FT components of DMFT were associated with lower oral impact scores. The self-perceived measures were also associated with oral impact scores and presented similar findings to that of the clinical oral health measures.

Conclusions

Untreated decay significantly impacted daily performances, especially eating, sleeping, studying, and social contact. The findings are of importance to public health practitioners for reporting, treating, and preventing oral health problems in children, and eventually contributing to better oral health-related quality of life.

Effect of oral health literacy on self-reported tooth loss: A multiple mediation analysis

BACKGROUND

This study aims to investigate the mediating pathways of oral health literacy (OHL) and oral health-related behaviours on the relationship between education and self-reported tooth loss among Australian adults.

METHODS

Data used for studying the effects of mediating pathways are from the National Dental Telephone Interview Survey 2013, a random sample survey of Australian adults aged 18+ years. To study the mediating effects, we use counterfactual-based analysis. To decompose the effect of multiple mediator's alternate, to natural effect, methods such as interventional effects have been proposed. In this paper, we use these approaches to decompose the effect between education, OHL and oral health-related behaviours on self-reported tooth loss. Sensitivity analysis was performed for unmeasured confounding with multiple mediators.

RESULTS

Data were available for 2936 Australian adults. The prevalence of persons with ≥12 self-reported tooth loss was approximately 15%. The average total causal effect from the low education group was nearly 150%, and the interventional indirect effect through OHL and the dependence of oral health-related behaviours on OHL to more than 12 missing teeth were 20% and 120%, respectively, higher than in the high education group. Sensitivity analysis indicated if the difference in the prevalence of unmeasured confounder is as big as 6% the direct effect and the indirect effect remains as observed.

CONCLUSIONS

An additional two-fifths reduction on having more than 12 missing teeth for Australian adults with lower education level could be achieved if the proportion of lower OHL was decreased and optimal dental behaviours were increased.

Predictors of Unmet Dental Health Needs in US Adults in 2018: A Cross-Sectional Analysis

OBJECTIVE

To identify predictors of unmet dental needs for adults 18 y of age or older in the United States.

METHOD

Using the Aday and Andersen framework and data from the 2018 Behavioral Risk Factor Surveillance System (BRFSS), we ran logistic regression to estimate predictors for adults of not having a dental visit within 5 y and having lost any teeth using a national sample of 155,060 survey respondents.

RESULTS

Results showed that predisposing factors (age, race/ethnicity, gender, and educational attainment) and enabling factors (income and health insurance status) are important predictors for losing teeth due to decay or gum disease. Men, the elderly, and less educated and low-income residents were less likely to have seen a dentist within the past 5 y and more likely to have lost their permanent teeth. Compared to non-Hispanic White adults, Hispanics adults were more likely to have had a dental visit within the past 5 y. Unmet dental needs varied across states. People living in states with extensive Medicaid dental care benefit coverage were less likely to lose their teeth and more likely to have had a dental visit within the past 5 y.

CONCLUSION

Efforts to improve oral health should address unmet dental needs of men and adults with low socioeconomic status. Studying the variation between state oral health care programs could further our understanding of how public policy can improve population oral health.

KNOWLEDGE TRANSFER STATEMENT

Men, non-Hispanic Blacks, mixed and other race minorities, and low socioeconomic status adults are most at risk of unmet dental needs. States can address these needs by expanding Medicaid coverage for adults.

Which patient and doctor behaviours make a medical consultation more effective from a patient point of view. Results from a European multicentre study in 31 countries

OBJECTIVE

To assess European patients' preferences regarding seven aspects of doctor-patient communication.

METHODS

6049 patients from 31 European countries evaluated 21 doctor and 12 patient behaviours, through a patient-generated questionnaire (PCVq). Multilevel models explored the effects of patient characteristics, contextual and cultural dimensions on preferences.

RESULTS

Patients attributed more responsibility to doctors, by giving greater importance to doctor than to patient factors, in particular to Treating the patient as a partner and as a person and Continuity of care. Gender, age, education, the presence of chronic illness and two of Hofstede's cultural dimensions, Individualism and Indulgence, showed differential evaluations among patients. Women gave greater importance to all seven communication aspects, older patients to being prepared for the consultation, lower educated patients to Treating patient as a person and Thoughtful planning. Patients from countries with an indulgent background rated all seven communication aspects of greater importance. A more individualistic orientation was related to lower importance regarding the four doctor's factors and the patient factor Open and Honest.

CONCLUSIONS

Treating the patient as a person and providing continuity of care emerged as universal values.

PRACTICE IMPLICATIONS

The findings should represent a landmark for the adaptation of patient-generated communication guidelines and programs in Europe.

Comprehension of Japanese oral care-related terms among caregivers and nurses, as assessed using a newly developed instrument

OBJECTIVES

(i) To assess comprehension of oral care-related terms among caregivers and nurses working at long-term care facilities, using a newly developed test; (ii) to analyse the effect of participant characteristics on their comprehension.

BACKGROUND

Effective mutual communication between dental professionals and caregivers/nurses is essential for providing information on daily oral care for institutionalised elders.

METHODS

A 36-item word-knowledge test in Japanese was developed to assess comprehension of oral care-related terms. The test was administered to a convenience sample of 236 nursing staff (198 caregivers and 38 nurses) at six long-term care facilities in Niigata City, Japan, and its reliability and validity were verified. Associations of participant characteristics with their responses were investigated by multiple regression analysis.

RESULTS

Mean percentage of correct responses (accuracy rate) for nursing staff was approximately 62% (highest for oral care products and lowest for prosthodontic terms). Test internal reliability was high (Cronbach's alpha >0.8). Concurrent validity (test ability to distinguish between characteristically different groups) was confirmed. Mean accuracy rate was significantly higher among nurses (78.5 ± 19.3%) than among caregivers (58.7 ± 22.8%), and among respondents with interest in oral care (64.2 ± 21.1%) than among those with no such interest (51.5 ± 28.9%).

CONCLUSION

The word-knowledge test was valid and reliable for nursing staff of six long-term care facilities in Niigata City. Their comprehension was low for perioral and intraoral structures, related symptom and disease names, and prosthodontics terms related to oral care. Understanding of oral care-related terms among the nursing staff was related to their occupation and interest in oral care.

A pilot study to assess oral health literacy by comparing a word recognition and comprehension tool

Background

Oral health literacy is important to oral health outcomes. Very little has been established on comparing word recognition to comprehension in oral health literacy especially in older adults. Our goal was to compare methods to measure oral health literacy in older adults by using the Rapid Estimate of Literacy in Dentistry (REALD-30) tool including word recognition and comprehension and by assessing comprehension of a brochure about dry mouth.

Methods

75 males and 75 females were recruited from the University of Connecticut Dental practice. Participants were English speakers and at least 50 years of age. They were asked to read the REALD-30 words out loud (word recognition) and then define them (comprehension). Each correctly-pronounced and defined word was scored 1 for total REALD-30 word recognition and REALD-30 comprehension scores of 0–30. Participants then read the National Institute of Dental and Craniofacial Research brochure “Dry Mouth” and answered three questions defining dry mouth, causes and treatment. Participants also completed a survey on dental behavior.

Results

Participants scored higher on REALD-30 word recognition with a mean of 22.98 (SD = 5.1) compared to REALD-30 comprehension with a mean of 16.1 (SD = 4.3). The mean score on the brochure comprehension was 5.1 of a possible total of 7 (SD = 1.6). Pearson correlations demonstrated significant associations among the three measures. Multivariate regression showed that females and those with higher education had significantly higher scores on REALD-30 word-recognition, and dry mouth brochure questions. Being white was significantly related to higher REALD-30 recognition and comprehension scores but not to the scores on the brochure.

Conclusions

This pilot study demonstrates the feasibility of using the REALD-30 and a brochure to assess literacy in a University setting among older adults. Participants had higher scores on the word recognition than on comprehension agreeing with other studies that recognition does not imply understanding.

Health literacy: a pathway to better oral health

OBJECTIVES

We examined whether health literacy was associated with self-rated oral health status and whether the relationship was mediated by patient-dentist communication and dental care patterns.

METHODS

We tested a path model with data collected from 2 waves of telephone surveys (baseline, 2009-2010; follow-up, 2011) of individuals residing in 36 rural census tracts in northern Florida (final sample size n = 1799).

RESULTS

Higher levels of health literacy were associated with better self-rated oral health status (B = 0.091; P < .001). In addition, higher levels of health literacy were associated with better patient-dentist communication, which in turn corresponded with patterns of regular dental care and better self-rated oral health (B = 0.003; P = .01).

CONCLUSIONS

Our study showed that, beyond the often-reported effects of gender, race, education, financial status, and access to dental care, it is also important to consider the influence of health literacy and quality of patient-dentist communication on oral health status. Improved patient-dentist communication is needed as an initial step in improving the population's oral health.
