A missed primary care appointment correlates with a subsequent emergency department visit among children with asthma.

OBJECTIVE: Since the Affordable Care Act's implementation, emergency department (ED) visits have increased. Poor asthma control increases the risk of acute exacerbations and preventable ED visits. The Centers for Medicare and Medicaid Services support the reduction of preventable ED visits to reduce healthcare spending. Implementation of interventions to avoid preventable ED visits has become a priority for many healthcare systems yet little data exist examining children's missed asthma management primary care (PC) appointments and subsequent ED visits.

METHODS: Longitudinal, retrospective review at a children's hospital was conducted for children with diagnosed asthma (ICD-9 493.xx), ages 2-18 years, scheduled for a PC visit between January 1, 2010, and June 30, 2012 (N = 3895). Records were cross-referenced with all asthma-related ED visits from January 1, 2010 to December 31, 2012. Logistic regression with maximum likelihood estimation was conducted.

RESULTS: None of the children who completed a PC appointment experienced an ED visit in the subsequent 6 months whereas 2.7% of those with missed PC appointments had an ED visit (χ2 = 64.28, p <.0001). Males were significantly more likely to have an ED visit following a missed PC appointment than females (χ2 = 34.37, p <.0001). There was a statistically significant interaction of sex × age. Younger children (<12 years) made more visits than older children.

CONCLUSIONS: The importance of adherence to PC appointments for children with asthma as one mechanism for preventing ED visits was demonstrated. Interventions targeting missed visits could decrease asthma-related morbidity, preventable ED visits, and healthcare costs.
