Study Description

Brief Summary

The purpose of this research is to develop and evaluate an mHealth communication intervention designed to improve asthma medication adherence amongst rural Latino children in South Carolina.

Asthma	Device: AsthmaMD mobile application Other: Usual care	N/A

Detailed Description

The overall prevalence of asthma is highest in the US south, which has one of the fastest growing Latino populations in the country. In South Carolina, asthma is the leading cause of children's hospitalization and emergency department (ED) visits, with significant direct and indirect costs. Although rates of childhood asthma are lower in Latinos (with the exception of children of Puerto Rican origin) than in whites, Latinos are more likely to have a higher incidence of uncontrolled asthma symptoms, ED visits, repeat hospitalizations, and poorer health in general. Current interventions addressing asthma control include outpatient clinic based and home visitation programs. Rural Latino families have difficulty participating with these types of programs due to work, family, and transportation constraints.

The adaptability of mobile apps holds the potential to target the unique challenges to management experienced by rural Latino children with asthma experience. The goal of this study is to develop and evaluate a patient-centered collaborative intervention between rural Latino children with asthma and their families, school-based nursing, and primary care providers, facilitated by the use of a smart phone based bilingual mobile app. The specific aims are to:

Produce and validate a Spanish translation of an existing asthma management app and evaluate its usability with Latino parents of children with asthma; and
Develop and evaluate a triadic, patient-centered asthma intervention preliminary protocol, facilitated by the bilingual mobile app validated in aim 1.

Outcome Measures

Primary Outcome Measures

Mobile app usability and acceptability [1 week]
Participants with Spanish as first language use the translated app for ease of use and identification of interface problems
Preliminary protocol testing of mobile app-facilitated triadic communication [3 months]
Develop and evaluate a triadic, patient-centered asthma intervention preliminary protocol, facilitated by the Spanish language mobile app. Post-intervention data regarding the experiences of the participants in this collaborative intervention will be obtained through a post-intervention focus group facilitated by the PI with the PCPs and school nurses, and five interviews conducted by a bilingual research assistant with the Latino families.
Investigate the feasibility of the patient-centered asthma intervention [6 months]
Investigate the feasibility of the patient-centered asthma intervention from aim 2 using a wait list randomized control trial (RCT) to investigate the effects of the intervention on school days missed and medication adherence. Anticipated quantitative data includes the information entered into the app, encrypted, and transmitted to the school nurse by the parent/caregiver. These data will include selected NIH/AHRQ standardized asthma outcomes,47 including the primary outcome measures of medication adherence information (asthma medication ratio48 - predictive of childhood asthma ED visits and hospitalizations) and school days missed.

Secondary Outcome Measures

Medication adherence and lung function tests [6 months]
Secondary outcome measures include frequency of rescue inhaler use, as well as asthma exacerbations, outpatient clinic visits, and emergency department visits. Lung capacity will be obtained pre- and post-intervention/bronchodilation using spirometry49 to obtain relevant lung function variables such as FEV1 and FEV1/FVC. Measures from the control group will include medication counts, number of asthma exacerbations, ED/outpatient clinic visits, and spirometry measures on enrollment, during the intervention phase, and again at the end of the intervention.
