Effect of home-based asthma medication therapy management program on pediatric African Americans with uncontrolled
Insights
A pharmacist-led medication therapy management (MTM) program significantly reduced asthma exacerbations and emergency department visits for African American children. The intervention also improved asthma control, caregiver knowledge, and medication adherence.
Area of Science:
- Pediatric Asthma Management
- Health Services Research
- Pharmacotherapy
Background:
- Asthma exacerbations pose a significant burden on pediatric populations, particularly among African American children in state Medicaid plans.
- Medication Therapy Management (MTM) programs delivered by pharmacists can potentially improve health outcomes and reduce healthcare utilization.
Purpose of the Study:
- To evaluate the impact of a pharmacist-delivered home-based and telephonic MTM program on asthma exacerbations in African American children.
- To assess changes in asthma control, caregiver knowledge, and medication adherence.
Main Methods:
- A quasi-experimental, pre-post prospective study design was employed with patients serving as their own controls over a 12-month intervention period.
- Pharmacist home visits and telephonic outreach were conducted at scheduled intervals.
- Outcomes included emergency department (ED) visits, asthma control assessments, caregiver asthma knowledge, Asthma Control Test scores, and medication adherence.
Main Results:
- A significant reduction in asthma-related ED visits was observed, decreasing from 122 in the year prior to enrollment to 57 after the intervention (P < 0.001).
- Improved asthma control was noted, with pharmacist assessments showing an increase from 58.7% at baseline to 76.8% at the final visit.
- Statistically significant improvements were found in caregiver asthma knowledge (P < 0.05) and medication adherence (P = 0.035).
Conclusions:
- Pharmacist-led MTM programs, incorporating home-based and telephonic interventions, are effective in reducing asthma exacerbations and ED visits in pediatric patients.
- The program demonstrated positive effects on asthma control, caregiver knowledge, and medication adherence, highlighting its value in managing pediatric asthma within a Medicaid population.
Objectives:
To determine the impact of a pharmacist home-based and telephonic medication therapy management (MTM) program for African American children enrolled in a state Medicaid plan with asthma exacerbations. Caregivers' knowledge of asthma is described.
Design:
This study was a quasi-experimental, pre-post prospective study with 2 phases: a pre-phase followed by a 12-month intervention post-phase in which each patient served as their own control. Pharmacists were sent to the patients' homes to provide MTM at weeks 1, 24, and 48 while pharmacy students provided telephonic outreach at weeks 4, 8, 12, and 36.
Setting:
A local Medicaid managed care organization.
Participants:
Pediatric African American patients (4-17 years old) with uncontrolled asthma.
Main Outcome Measures:
Outcomes included emergency department (ED) visits, change in pharmacist assessment of asthma control, change in asthma knowledge test, change in Asthma Control Test, and change in medication adherence score.
Results:
Overall, 366 pediatric patients (4-17 years old) were enrolled in this program over a 1-year period. Among the patients who were enrolled in the program, there were 122 asthma-related ED visits in the year preceding enrollment compared to 57 ED visits after their first home-based visit (P < 0.001). Although only 102 patients completed the study, more patients were assessed by the pharmacists as having well-controlled asthma at the final visit (76.8%) than at baseline (58.7%). Based on the Asthma Control Test, more patients reported uncontrolled asthma at baseline (47.5%) than at the final visit (39%). There was a statistically significant increase in the Asthma Knowledge Test (P < 0.05) and the Medication Adherence Assessment (P = 0.035) among patients compared with baseline.
Conclusion:
Rates of asthma exacerbations requiring an ED visit were substantially lower in the year after the initial pharmacist visit compared with the year preceding enrollment in the medication therapy management program.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
