Disparities in asthma medication dispensing patterns: the case of pediatric asthma in Puerto Rico.

BACKGROUND: Disparities exist in asthma medication dispensing between children with public insurance and those with private insurance under a Managed Care Medicaid system in Puerto Rico. OBJECTIVES: Island-wide medical claims data were used to examine the extent to which differences between the private and public health care sectors affect medication dispensing and health care utilization among asthmatic children. METHODS: Children 3-18 years old with at least one service claim [outpatient, hospitalization, or emergency department (ED) visit] for asthma or reactive airway disease from 2005 to 2006 were selected. Chi-square analyses compared medication dispensing and health care utilization between the public and private sectors. Negative binomial regression identified factors associated with the mean dispensing rate of prescriptions for anti-inflammatory controller medication (CM). RESULTS: Private insurance families (n = 28,088) were dispensed significantly more CM (48.3% vs. 12.0%) and quick relief medication (47.4% vs. 44.6%) than public insurance families (n = 13,220). The dispensing of inhaled corticosteroids (24.4% vs. 6.7%) and leukotriene modifiers and cromolyn (31.4% vs. 5.7%) was dramatically higher in the private sector. In contrast, emergency room use was significantly higher among public insurance children (51.7% vs. 13.8%). Multivariate analysis showed that age, number of ß-agonists, and type of insurance was associated with CM dispensing; private insurance showed the greatest effect. CONCLUSION: Asthmatic Puerto Rican children enrolled in public insurance were significantly less likely to be dispensed CM than children with private insurance; suggesting that under-treatment of public insured children may substantially contribute to increased asthma morbidity in this population as evidenced by significantly higher rates of ED visits. CAPSULE SUMMARY: A disparity exists in asthma medication dispensing between children with public insurance compared with those with private insurance under a Managed Care Medicaid system in Puerto Rico. If asthma disparities in medication dispensing are to be reduced, then a better understanding of the complex ways in which multiple variables related to the health care system policies, socioeconomic factors, family and provider interactions, as well as the relative weight that each one contributes to the observed inequalities is needed.

Barriers to Prescribing Controller Anti Inflammatory Medication among Puerto Rican Asthmatic Children with Public Insurance: Results of National Survey of Pediatricians.

BACKGROUND: There are substantial disparities in dispensing patterns of long term control medications for asthma among children in Puerto Rico with public insurance as compared to those with private insurance. Public health insurance policy in Puerto Rico includes the cost of medications in the capitation paid to the primary care physicians and clinics. METHODS: Survey questionnaires were mailed to all pediatricians enrolled in the Puerto Rico College of Physicians (n=798) in addition to some pediatricians not enrolled in the College (n=25) for a total of 823 pediatricians. Of these, 722 were eligible pediatricians with 458 responding to the survey for a response rate of 63.4%. RESULTS: Most of the respondents expressed being moderately to very familiar with the National Asthma Education and Prevention Program (NAEPP) guidelines (71.7%) and with the NAEPP recommendations for controller asthma medication use (73.5%). Inadequate capitation to cover asthma medication (86.2%) and lack of adequate health insurance coverage of the patient (83.2%) however, were the most frequent barriers reported by pediatricians for prescribing controller asthma medication to children with public health insurance. The most frequent strategies used to provide controller asthma medication to these children were prescription of oral medications (59.5%) and giving away samples (44.7%). CONCLUSIONS: Current public health insurance policy in Puerto Rico creates a disincentive to the appropriate prescription of long term control medication for children with asthma. To improve the quality of asthma care of children in Puerto Rico, revision of this public health insurance policy is necessary.
