Effectiveness of preventive dental treatments by physicians for young Medicaid enrollees.

ABSTRACT:

Objective

To estimate the effectiveness of a medical office-based preventive dental program (Into the Mouths of Babes [IMB]), which included fluoride varnish application, in reducing treatments related to dental caries.

Methods

We used longitudinal claims and enrollment data for all children aged 72 months or younger enrolled in North Carolina Medicaid from 2000 through 2006. Regression analyses compared subgroups of children who received up to 6 IMB visits at ages 6 to 35 months with children who received no IMB visits. Analyses were adjusted for child and area characteristics.

Results

Children enrolled in North Carolina Medicaid with ? 4 IMB visits experienced, on average, a 17% reduction in dental-caries-related treatments up to 6 years of age compared with children with no IMB visits. When we simulated data for initial IMB visits at 12 and 15 months of age, there was a cumulative 49% reduction in caries-related treatments at 17 months of age. The cumulative effectiveness declined because of an increase in treatments from 24 to 36 months, an increase in referrals for dental caries occurred with increasing time since fluoride application, and emergence of teeth not initially treated with fluoride.

Conclusions

North Carolina's IMB program was effective in reducing caries-related treatments for children with ? 4 IMB visits. Multiple applications of fluoride at the time of primary tooth emergence seem to be most beneficial. Referrals to dentists for treatment of existing disease detected by physicians during IMB implementation limited the cumulative reductions in caries-related treatments, but also contributed to improved oral health.

Project description:ObjectiveThe goal of this study was to use claims data linked with community-level measures to evaluate the impact of preventive services on the time to subsequent restorative, advanced restorative, and complex dental treatment among children enrolled in the Virginia Medicaid program.MethodsFour data sources were used (dental claims, eligibility files, American Community Survey, and Area Health Resource Files) for fiscal years 2011 to 2018. The outcomes of interest were time to first treatment services from birth. The treatment outcomes were basic restorative treatment, advanced restorative treatment, or complex treatment. The independent variable was a preventive service prior to a treatment service. Time-to-event curves were estimated and compared using a log-rank test. Propensity score-matched univariate and multivariate Cox proportional hazards frailty models with an inverse probability censoring weighting correction estimated hazard ratios (HRs) for treatment outcomes comparing use of preventive services while controlling for patient demographic, geospatial, and county-level socioeconomic status measures.ResultsThe analysis included 430,594 children (10,204,182 claims). A log-rank test showed significant differences (P < 0.001) between the times to treatment of those who had a preventive service and those who did not have a preventive service prior to a treatment service. Both Kaplan-Meier curves and the adjusted HR (1.88; 95% confidence interval [CI], 1.46-2.15) indicated that children without preventive services were more likely to have basic restorative treatment at an earlier age along with advanced restorative treatment (HR, 1.52; 95% CI, 1.28-1.80) and complex treatment (HR, 2.13; 95% CI, 1.68-2.61).ConclusionsIn a population of Medicaid-enrolled children, children who did not receive preventive services were significantly more likely to have treatment at an earlier age than those who did receive preventive services.Knowledge transfer statementThis study examines the impact of the utilization of preventive dental services since birth and the subsequent dental treatment for children enrolled in a dental Medicaid program. This study also examines the influence of preventive care on dental complexity of treatment for these children. Findings can inform federal and state policy planning of dental Medicaid programs as well as interventions to improve referral systems for the early use of preventive dental services and the establishment of a dental home.

Project description:ImportanceDental surgery under general anesthesia (DGA) is an ineffective, costly treatment for caries. Interventions to reduce the need for DGA are challenging because children's parents may not seek care until surgery is required. Community water fluoridation (CWF) effectively prevents early childhood caries, but its effectiveness in reducing severe early childhood caries is unknown.ObjectiveTo determine whether access to CWF is associated with the prevalence of DGA.Design, setting, and participantsThis is a cross-sectional analysis of Medicaid claims data from 2011 to 2012. Deidentified data were derived from Medicaid claims and enrollee files for Massachusetts, Texas, Connecticut, Illinois, and Florida for children aged 9 years and younger enrolled in either a fee-for-service or managed care plan through their state's Medicaid program. Linear regression models tested for associations between CWF and covariates. Multivariable linear regression models tested for associations between CWF and outcomes. Regression models included clustered SEs at the county level. Data analysis was performed from December 2018 to March 2020.ExposuresAccess to CWF was determined by estimating the proportion of a county's total population that had access to a fluoridated public water system.Main outcomes and measuresThe main outcome was county-level DGA prevalence. Other outcomes were caries-related visit prevalence and patient quality indicators (asthma and diabetes). Covariates included county-level demographic, socioeconomic, and dental practitioner variables.ResultsA total of 436 counties within 5 states per year (872 county-year observations), were included in the analysis. Adjusted analysis revealed that a 10% increase in the proportion of county's population access to CWF was associated with lower caries-related visit prevalence (-0.45 percentage points; 95% CI, -0.59 to -0.31 percentage points; P < .001). Increasing CWF access in 10% increments was associated with decreased DGA prevalence in unadjusted analysis (-0.39 percentage points; 95% CI, -0.67 to -0.12 percentage points; P = .006) but not in adjusted analysis (-0.23 percentage points; 95% CI, -0.49 to 0.02 percentage points; P = .07). Increasing the proportion of county's access to CWF by 10% was not associated with the prevalence of asthma-related exacerbations (-0.02 percentage points; 95% CI, -0.10 to 0.05 percentage points; P = .53) or diabetes-related exacerbations (-0.0003 percentage points; 95% CI, -0.0014 to 0.0009 percentage points; P = .66).Conclusions and relevanceThis study extends our understanding of CWF's benefits for children's oral health. Specifically, these findings suggest that increasing a population's access to CWF's is associated with decreased caries-related visits and may also be associated with use of dental surgical services within high-risk populations.
