Association between Health Care Utilization with Asthma Control Levels among a Sample of Adult Patients in Puerto Rico.

OBJECTIVE: Asthma is an important and serious public health problem in Puerto Rico; however, very few studies measuring the association between health care utilization and asthma control levels in adult asthma patients in Puerto Rico have been done. METHODS: This study is secondary analysis of an observational and cross-sectional database generated by the Latin American Asthma Insights and Management (LA AIM) survey. Our sub-sample consisted of adults 18 years or older living with asthma, representing a total of 343 individuals. This study determined the numbers of ambulatory physician visits, emergency visits to a physician or an emergency room, and hospitalizations that took place the 12 months prior to the survey. Patients were characterized as having well-controlled, partly controlled, or uncontrolled asthma. Descriptive and inferential statistics were performed to detect differences in the mean and number of events for physician visits, emergency visits, and hospitalizations by asthma control groups. RESULTS: After adjusting for age, sex, and chronic health conditions (other than asthma), adult asthma patients with controlled asthma had 92.0% fewer physician visits, 82.5% fewer emergency visits, and 92.2% fewer hospitalizations than did those with uncontrolled asthma. CONCLUSION: Interventions geared toward controlling asthma symptoms and clinical manifestations in adults asthma patients-which interventions might include strategies for controlling environmental risk factors, increasing patient and family education with regard to asthma management, and boosting the use of appropriate and effective medications-may have significant potential in terms of reducing the direct and indirect costs of asthma, costs that have a critical impact on the whole health care system.

Medical Costs of Persons with Drug Use Disorders Among Medicaid Managed Care Beneficiaries in Puerto Rico : Comparison of the Direct Services Costs Incurred by Beneficiaries With and Without a Drug Use Disorder.

Drug use disorders (DUDs) can substantially increase the costs of health care, especially when left untreated. Yet, not much is known about the specific types of medical services that give rise to these cost differences. This study aimed to estimate the medical costs of beneficiaries with DUDs enrolled in the Medicaid Managed Care (MMC) program in Puerto Rico using claims data. These were compared to those of a matched group of patients without DUDs. On average, each beneficiary with a DUD incurred in $4539 annually on medical services compared to $2601 in the matched comparison group, a cost differential of $1938. Close to half of these additional medical costs (43.4%) were generated in the physical health services sector. Counts of service claims were also higher for beneficiaries with DUDs than for beneficiaries without DUDs in all service types, except in outpatient and laboratory services for physical health. A host of access strategies and treatment modalities should be tested to assess the extent to which providing adequate access and adequate treatment for a DUD can contribute to cost savings.
