Asthma is the most common chronic disease among children worldwide, with 80% of asthma related deaths occurring in low- and middle-income countries (LMICs), such as Peru. While evidence-based guidelines exist for asthma treatment and management, adherence to guideline-based practices is low in high-income country (HIC) and LMIC settings alike. There a clear need for effective, locally-tailored solutions to address the asthma treatment gap in low-income communities in LMICs, such as Peru. This study aims to develop and test a locally-adapted intervention package to improve adoption of self-management practices and utilization of preventive health services for asthma among children in Lima. There is a paucity of research regarding the development and testing of interventions to improve asthma self-management in LMIC settings, which experience unique or exacerbated barriers to receiving evidence-based care. To the investigators' knowledge, no studies have systematically developed and evaluated an asthma management program in Peru. Therefore, the long-term goal of this study is to disseminate locally appropriate asthma management strategies to reduce asthma-related emergency department visits and improve service utilization in LMIC settings. For the current study, the investigators will carry out a randomized controlled trial to test the effectiveness of the intervention package in a group of 110 children with asthma who will be randomized to the intervention (55 children) or no intervention (55 children) arm. Participants in the intervention group will receive case management from a designated nurse manager, who will provide ongoing educational, social, and self-management support during monthly follow-up home visits and text-message based communication. Participants will be followed up every month for data collection over a six-month period. Throughout the follow-up period, the investigators will collect data on asthma control, healthcare utilization, medication adherence, quality of life of children with asthma and the children's caregivers, caregiver mental health, fidelity to the intervention, and acceptability and feasibility. Ultimately, this study will inform the scientific community about effective strategies and treatment programs for asthma in low-income settings.

Children will receive basic asthma education, based on the National Heart, Lung, and Blood Institute "A Breath of Life" asthma education program. Children/caregivers in the intervention arm will also be assigned a designated nurse case manager who will provide home visits and be available via text message and phone-based support throughout follow-up. Intervention components: * Interactive education and support on use of an asthma action plan * Locally adapted patient-provider communication tool * Child-oriented educational materials in comic book format * Modeling and hands-on practice of inhaler technique (written instructions, in person, video) * Education regarding environmental trigger abatement * Patient navigation, home visits, and goal setting support from nurse manager

Change in Asthma Control as assessed by Childhood Asthma Control Test (cACT) Score
cACT (5-11 years of age) will be administered at baseline and monthly during the follow-up period. The cACT is scored by summing the scores for all items. Overall scores ranges from 0 to 27. Lower scores indicate poorer asthma control and higher scores indicate better asthma control. Scores 19 and below suggest impaired asthma control.
Time frame: Baseline, then monthly up to 6 months
Change in Asthma Control as assessed by Asthma Control Test (ACT) Score
ACT (12-17 years of age) will be administered at baseline and monthly during the follow-up period. The ACT is scored by summing the scores for all items. Overall score ranges from 5 to 25. Lower scores indicate poorer asthma control and higher scores indicate better asthma control. Scores 19 and below suggest impaired asthma control.
Time frame: Baseline, then monthly up to 6 months
Number of participants with at least one asthma-related ED or urgent care visit during the six-month follow-up period
Number with asthma-related emergency department (ED) or urgent care visits will be used to assess healthcare utilization.
Time frame: 6 months
Change in Adherence to Refills and Medications Scale-7 (ARMS-7) score
ARMS-7 will administered at baseline and monthly during the follow-up period. Score is calculated by summing the scores for all items. Overall score ranges between 7 and 28. Lower scores indicate better adherence.
Time frame: Baseline, then monthly up to 6 months
Medication adherence as assessed by Dose counter-measured medication use
Number of puffs used divided by the number of puffs indicated to be used over monthly follow-up period.
Time frame: 6 months
Quality of life as assessed by Pediatric Asthma Quality of Life Questionnaire (PAQLQ)-Mini
Measures disease-specific quality of life in children and adolescents with asthma. The PAQLQ-mini has 13 items, each scored on a 7-point Likert scale with "1" indicating severe impairment and "7" indicating no impairment. Score is calculated by taking the average of scores for each item. Higher scores indicate better quality of life. Range: \[1 to 7\].
Time frame: 6 months
Quality of life in caregivers of children and adolescents with asthma as assessed by Pediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ)
Measures quality of life in caregivers of children and adolescents with asthma. The PACQLQ has 13 items, each scored on a 7-point Likert scale with "1" indicating severe impairment and "7" indicating no impairment. Score is calculated by taking the average of scores for each item. Higher scores indicate better quality of life. Range: \[1 to 7\].
Time frame: 6 months
Depression as assessed by Patient Health Questionnaire-9 (PHQ-9)
Measures depressive symptoms. Will be administered to caregivers of children and adolescents with asthma. The PHQ-9 has nine items, each scored on a Likert scale from 0 to 3. Higher scores indicate more evidence of depressive disorder of greater severity of disorder. Scores are calculated by summing the scores for all items. Range: \[0 to 27\].
Time frame: 6 months
Number of participants with asthma-related hospitalizations
Count of participants (children) with at least one asthma-related hospitalization during six-month follow-up period.
Time frame: 6 months
Number of participants with all-cause emergency department (ED) or urgent care visits
Count of participants with at least one all-cause ED or urgent care visit during the six-month follow-up period.
Time frame: 6 months
Number of participants who attend two or more outpatient appointments with healthcare provider for asthma.
Count of participants who attend two or more outpatient appointments with healthcare provider for asthma over six-month follow-up period.
Time frame: 6 months
