Community Health Workers in Home Visits and Asthma Outcomes.

BACKGROUND: The Community Asthma Initiative (CAI) was included in the New England Asthma Innovations Collaborative, which received a Centers for Medicare and Medicaid Services (CMS) Innovation grant. Under this grant, CAI transitioned from a mixed community health worker and nurse model to a nurse-supervised community health worker model. CMS limited enrollment to patients with Medicaid and encouraged 3 home visits per family. METHODS: A total of 389 patients enrolled under the CMS grant at Boston Children's Hospital from 2013 to 2015 (CMS group) were compared with 733 CAI patients with Medicaid enrolled from 2005 to 2012 (comparison group). Changes in 5 asthma-related measures (emergency department visits, hospitalizations, physical activity limitations, missed school days, and parent and/or guardian missed workdays) were compared between baseline and 6 and 12 months postenrollment. Measures were analyzed as dichotomous variables using logistic regression. Numbers of occurrences were analyzed as continuous variables. Changes in quality of life (QoL) among the CMS group were examined through a 13-question survey with activity and emotional health subscales. RESULTS: Although patients in both groups exhibited improvement in all measures, the CMS group had greater odds of decreased hospitalizations (odds ratio 3.13 [95% confidence interval 1.49-6.59]), missed school days (1.91 [1.09-3.36]), and parent and/or guardian missed workdays (2.72 [1.15-6.41]) compared to the comparison group. Twelve months postenrollment, the CMS group experienced improvement in all QoL questions and subscales (all P values <.01). CONCLUSIONS: The CMS group showed improved outcomes for hospitalizations and missed school and workdays compared to the comparison group. The CMS group also exhibited significant improvement in QoL.

Adherence to adding inhaled corticosteroids to rescue therapy in a pragmatic trial with adults with asthma: A pilot study.

BACKGROUND: Underuse of guideline-recommended inhaled corticosteroids (ICS) controller therapy is a risk factor for greater asthma burden. ICS concomitantly used with rescue inhalers (Patient-Activated Reliever-Triggered ICS ['PARTICS']) reduced asthma exacerbations in efficacy trials, but whether PARTICS is effective in pragmatic trials is unknown. OBJECTIVE: We conducted this pilot to determine the feasibility of executing a large-scale pragmatic PARTICS trial and to improve study protocols. METHODS: Four sites recruited 33 Hispanic or black adults with persistent asthma, randomized them approximately 3:1 to intervention or usual care, and followed them for 12 weeks. All participants received asthma guideline-based educational videos; intervention participants received video-based instructions on implementing PARTICS plus usual medications. The study involved 1 randomization visit and monthly questionnaires. Timely questionnaire responses (±2 weeks) were monitored. Participants underwent qualitative phone interviews to assess self-reported adherence to PARTICS and understand barriers to completing study procedures. RESULTS: Timely questionnaire response rates were 61%, 64%, and 70% at 4, 8, and 12 weeks, respectively. Self-reported adherence to PARTICS was 76% (95% confidence interval [CI], 58%-94% [n = 21]), 88% (95%CI, 72%-100% [n = 16]), and 62% (95%CI, 36%-88% [n = 13]) at weeks 1, 6, and 12, respectively. Barriers to completing study procedures included difficulties with questionnaire access, remembering to use ICS and rescue inhalers together, and obtaining refills. Only 22% of participants recognized their short-acting bronchodilator as "reliever" or "rescue." CONCLUSION: Recruitment was feasible within the allocated period. Adherence to PARTICS was incomplete, questionnaire completion was suboptimal, and common rescue inhaler nomenclature usage was limited. We have modified the full study protocol to attempt to improve adherence to PARTICS and minimize barriers to study procedures. CLINICAL TRIALS REGISTRATION: pilot study for 'PeRson EmPowered Asthma Relief' (PREPARE, NCT02995733).

Community Asthma Initiative to Improve Health Outcomes and Reduce Disparities Among Children with Asthma.

Black and Hispanic children are hospitalized with complications of asthma at much higher rates than white children. The Boston Children's Hospital Community Asthma Initiative (CAI) provides asthma case management and home visits for children from low-income neighborhoods in Boston, Massachusetts, to address racial/ethnic health disparities in pediatric asthma outcomes. CAI objectives were to evaluate 1) case management data by parent/guardian report for health outcomes and 2) hospital administrative data for comparison between intervention and comparison groups. Data from parent/guardian reports indicate that CAI decreased the number of children with any (one or more) asthma-related hospitalizations (decrease of 79% at 12 months) and any asthma-related emergency department visits (decrease of 56% at 12 months) among children served, most of whom were non-Hispanic black or Hispanic. Hospital administrative data also indicate that the number of asthma-related hospitalizations per child significantly decreased among CAI participants compared with a comparison group. The CAI model has been replicated in other cities and states with adaptations to local cultural and systems variations. Health outcome and cost data have been used to contribute to a business case to educate legislators and insurers about outcomes and costs for this enhanced approach to care. Strong partnerships with public health, community, and housing agencies have allowed CAI to leverage its outcomes to expand systemic changes locally and statewide to reduce asthma morbidity.
