A Program to Change the Approach to Care of Children with Asthma in the Primary Care Setting Did Not Reduce Rates of Hospital Admissions: Lessons Learned from a Descriptive Study

Asthma is a critical global health issue. It affects people of all ages in countries throughout the world. The prevalence of asthma is increasing in most countries among young children who also represent the greatest proportion of health care utilization. Outpatient asthma-treatment programs managed by chest physicians or allergists have reduced hospitalizations, yet programs in pediatric offices have not successfully impacted hospitalizations. The Community Asthma Program (CAP) was designed to support pediatrician use of clinical guidelines in their everyday office practice. The goal was to reduce asthma hospitalizations by 15 percent from selected pediatric practices. A study was done in 4 pediatric practices closely associated with St. Louis Children’s Hospital. The program included a continuous quality improvement process quarterly

Sickle cell disease: Wheeze or asthma?

Sickle cell disease (SCD) is the most common life-limiting genetic disease among African Americans, affecting more than 100,000 people in the United States. Respiratory disorders in patients with sickle cell disease have been associated with increased morbidity and mortality. Associations between asthma and pain, acute chest syndrome (ACS), and even death have long been reported. More recently wheezing, even in the absence of an asthma diagnosis, has gained attention as a possible marker of SCD severity. Several challenges exist with regards to making the diagnosis of asthma in patients with SCD, including the high prevalence of wheezing, evidence of airway obstruction on pulmonary function testing, and/or airway hyperresponsiveness among patients with SCD. These features often occur in isolation, in the absence of other clinical criteria necessary for an asthma diagnosis. In this review we will summarize: 1) Our current understanding of the epidemiology of asthma, wheezing, airway obstruction, and airway responsiveness among patients with SCD; 2) The evidence supporting associations with SCD morbidity; 3) Our understanding of the pathophysiology of airway inflammation in SCD; 4) Current approaches to diagnosis and management of asthma in SCD; and 5) Future directions
