New asthma guidelines needed
TORONTO – Children with asthma who have a comorbid diagnosis of anxiety or depression are significantly more likely to make asthma-related visits to the emergency department, compared with their peers who do not have a mental health condition, results from a large administrative data analysis showed.
“There has been a fair bit of research on how comorbid mental health conditions can affect health care utilization for asthma in adults, but few studies have examined how comorbid mental health conditions like anxiety or depression can affect children with asthma,” one of the study authors, Caroline Neel, said in an interview in advance of the Pediatric Academic Societies meeting.

In all, the researchers identified 71,326 patients with asthma, with an overall rate of 16.3 ED visits per 100 child-years. Among these, children with a diagnosis of depression had significantly higher rates of ED visits (21.5 visits per 100 child-years; P less than .01), as did those with a diagnosis of anxiety (19.5 ED visits per 100 child-years; P less than .01). Being enrolled in a Medicaid managed care plan or Medicaid fee-for-service plan also increased the rates of asthma-related ED visits (20.3 and 21.5 ED visits per 100 child-years, respectively; P less than .01 for both associations.)
“We were surprised to see that anxiety and depression seemed to increase asthma emergency department visits as much as other medical chronic illnesses like cystic fibrosis or sickle cell disease, and that kids on Medicaid, who tend to be our poorer kids, also had an independent risk of going to the emergency department,” Ms. Neel said. “Having Medicaid as well as anxiety or depression were independently related to going to the emergency room for asthma, so the study suggests that some of our highest-risk kids for asthma have multiple different contributors to getting sick and needing to go to the emergency room for an asthma attack.”
She acknowledged certain limitations of the analysis, including its reliance on administrative claims data to identify whether or not children had a diagnosis of anxiety or depression. “This doesn’t necessarily identify all the kids who may have these mental health conditions, since sometimes providers are less likely to document a diagnosis of a mental health conditions for children,” she said. “However, we still saw a significant association between a comorbid mental health condition and emergency department use for asthma, despite the potential that mental health conditions may have been under reported.”
