Determinants of Tooth Loss in a Medicaid Adult Population

BACKGROUND

The objective of this retrospective cohort study is to examine the determinants of tooth loss in a Medicaid-enrolled population using claims data from 2016 to 2018.

METHODS

Deidentified administrative claims data for Medicaid-enrolled adults between the ages of 50 and 90 y in 2016 to 2018 were examined using the IBM Watson MarketScan Medicaid Database. The sample size was 91,468. The entire sample was divided into 2 cohorts: no tooth loss cohort (n = 54,786) and tooth loss cohort (n = 36,682). The tooth loss cohort was further divided into 2 groups: 1 to 5 teeth lost (n = 29,141) and 6 or more teeth lost (n = 7,541). Tooth loss was described by age, gender, race, number of commodities, and if periodontal treatment was performed. Logistic regression models were conducted to examine factors associated with tooth loss.

RESULTS

Within the tooth loss cohort, the patients who had periodontal treatment had higher odds of losing at least 1 tooth (odds ratio [OR], 1.15; confidence interval [CI], 1.10-1.20) and lower odds of losing 6 or more teeth (OR, 0.25; CI, 0.22-0.29). In the regression analysis, the predictive margins of tooth loss for 1 tooth and 6 or more teeth follow a linear path. Compared to no comorbidities, the odds of losing 6 or more teeth increased with 1, 2, or 3+ comorbidities.

KNOWLEDGE TRANSFER STATEMENT

This study provides significant information about the quantification of comorbidities and its direct correlation with the increased odds of tooth loss. This study also highlighted the protective effect of periodontal treatment on tooth loss. This knowledge can be useful to dental care providers to understand the risk of tooth loss in their patient population.

The Effect of Continuous Versus Pregnancy-Only Medicaid Eligibility on Routine Postpartum Care in Wisconsin, 2011-2015

OBJECTIVE

To compare patterns of routine postpartum health care utilization for women in Wisconsin with continuous Medicaid eligibility versus pregnancy-only Medicaid METHODS: This analysis used Medicaid records and linked infant birth certificates for Medicaid paid births in Wisconsin during 2011-2015 (n = 105,718). We determined if women had continuous or pregnancy-only eligibility from the Medicaid eligibility file. We used a standard list of billing codes to identify if women received routine postpartum care. We examined maternal characteristics and receipt of postpartum care overall and by Medicaid eligibility category. Finally, we used a binomial model to calculate the relationship between Medicaid eligibility category and receipt of postpartum care, adjusted for maternal characteristics.

RESULTS

Women with continuous Medicaid had profiles more consistent with low postpartum visit attendance rates (e.g., younger, more likely to use tobacco) than women with pregnancy-only Medicaid. However, after adjusting for maternal characteristics, women with continuous Medicaid eligibility had a postpartum visit rate that was 6 percentage points higher than the rate for women with pregnancy-only Medicaid (RD: 6.27, 95% CI 5.72, 6.82).

CONCLUSIONS FOR PRACTICE

Women with pregnancy-only Medicaid were less likely to have received routine postpartum care than women with continuous Medicaid. Medicaid coverage beyond the current guaranteed 60 days postpartum could help provide more women access to postpartum care.

Long-acting reversible contraceptive utilization after policy change increasing device reimbursement to wholesale acquisition cost in Louisiana

BACKGROUND

Unintended pregnancies, occurring in nearly 1 out of every 2 (45%) pregnancies in the United States, are associated with adverse health and social outcomes for the infant and the mother. The risk of unintended pregnancies is significantly reduced when women use long-acting reversible contraceptives, namely intrauterine devices and implants. Inadequate reimbursement for long-acting reversible contraceptive devices may be an access barrier to long-acting reversible contraceptive uptake. In 2014, the Louisiana Department of Health Bureau of Health Services Financing implemented a policy change that increased the Medicaid reimbursement rates for acquiring long-acting reversible contraceptive devices to the wholesale acquisition cost.

OBJECTIVE

To examine the association of a Medicaid policy change that increased the long-acting reversible contraceptive device reimbursement rate to the wholesale acquisition cost (ie, price set by the manufacturers) on long-acting reversible contraceptive uptake among women at risk for unintended pregnancy.

MATERIALS AND METHODS

This retrospective, repeated cross-sectional study used 2013-2015 Louisiana Medicaid claims data and contraceptive provision measures to assess associations between patient (age, race, urban/rural residence, postpartum status) and provider (urban/rural location, specialty) characteristics and long-acting reversible contraceptive uptake among contraceptive users (N = 193,623) using bivariate and logistic regression analyses.

RESULTS

After long-acting reversible contraceptive reimbursement increased, there was a 2-fold likelihood increase in use in 2015 vs 2013 (odds ratio, 2.08; 95% confidence interval, 1.69-2.55). Long-acting reversible contraceptive uptake was more likely across all patient and provider subgroups in 2015 vs 2013 but notably among patients receiving contraceptive care from family planning clinics (odds ratio, 3.93; 95% confidence interval, 2.34-6.62).

CONCLUSION

Removal of a provider-level financial barrier to long-acting reversible contraceptive provision was associated with increased long-acting reversible contraceptive uptake among women at risk for unintended pregnancy. Efforts to improve long-acting reversible contraceptive access should focus on equitable healthcare reimbursement for healthcare providers of reproductive-aged women.

Uncovering Longitudinal Health Care Behaviors for Millions of Medicaid Enrollees: A Multistate Comparison of Pediatric Asthma Utilization

BACKGROUND

This study introduces a framework for analyzing and visualizing health care utilization for millions of children, with a focus on pediatric asthma, one of the major chronic respiratory conditions.

METHODS

The data source is the 2005 to 2012 Medicaid Analytic Extract claims for 10 Southeast states. The study population consists of Medicaid-enrolled children with persistent asthma. We translate multiyear, individual-level medical claims into sequences of discrete utilization events, which are modeled using Markov renewal processes and model-based clustering. Network analysis is used to visualize utilization profiles. The method is general, allowing the study of other chronic conditions.

RESULTS

The study population consists of 1.5 million children with persistent asthma. All states have profiles with high probability of asthma controller medication, as large as 60.6% to 90.2% of the state study population. The probability of consecutive asthma controller prescriptions ranges between 0.75 and 0.95. All states have utilization profiles with uncontrolled asthma with 4.5% to 22.9% of the state study population. The probability for controller medication is larger than for short-term medication after a physician visit but not after an emergency department (ED) visit or hospitalization. Transitions from ED or hospitalization generally have a lower probability into physician office (between 0.11 and 0.38) than into ED or hospitalization (between 0.20 and 0.59).

CONCLUSIONS

In most profiles, children who take asthma controller medication do so regularly. Follow-up physician office visits after an ED encounter or hospitalization are observed at a low rate across all states. Finally, all states have a proportion of children who have uncontrolled asthma, meaning they do not take controller medication while they have severe outcomes.

Comparative persistence on β-blockers versus calcium channel blockers for ventricular rate control in nonelderly patients with atrial fibrillation

BACKGROUND

For patients with atrial fibrillation (AF), early treatment is essential to prevent serious complications such as stroke. Several randomized clinical trials have shown that rate-control may be as effective as rhythm-control medications, whereas the latter have serious side effects. Little evidence exists, however, about which class of rate-control medication-β-blockers (BBs) or calcium channel blockers (CCBs)-may be superior.

OBJECTIVE

The objective was to compare the long-term persistence on BBs versus CCBs in nonelderly adult patients with AF.

METHODS

A longitudinal retrospective cohort study for patients 40 to 60 years old with newly diagnosed AF (identified by ICD-9 code 427.31) was performed using data from Ohio Medicaid physician, institutional, and pharmacy claims from January 2006 through June 2011. A Cox proportional hazard regression, with time to change out of rate-control therapy as the dependent variable, was estimated to compare persistence on (proxy for effectiveness of) rate-control medication across drug classes. A propensity-score analysis was used to control for selection bias. Additional covariates included age, development of heart failure, and medication adherence.

RESULTS

Out of 1239 patients included in the cohort, 1016 received a BB; 223 received a CCB. Over time, patients on CCBs were significantly more likely to switch out of rate-control therapy (hazard ratio = 1.89; 95% CI = 1.14-3.09) than patients on BBs.

CONCLUSIONS

Evidence suggests that nonelderly AF patients, when prescribed rate-control therapy, persist longer on BBs than CCBs. Because this is the first long-term study comparing the 2 drug classes in the nonelderly population, further research is suggested.
