Little is known about the disposition of severe patients prior to treatment escalation. To classify patients by treatment step using pharmacy data and describe their economic and healthcare utilization, insurance status, and sociodemographic characteristics in the year prior to escalation to Global Initiative for Asthma (GINA) steps 4 and 5. ⋯ Prior to escalating treatment to GINA steps 4 and 5, individuals experienced significant annual medical expenditures, healthcare resource utilization and polypharmacy burden, which may reflect poorly controlled asthma and the need to escalate treatment. Medical claims data and utilization-based measures may be helpful in classifying individuals by GINA treatment step.

Concerns have been raised regarding cardiac side effects of continuous high-dose albuterol nebulization in status asthmaticus management. Our study goal was to determine prevalence and potential risk factors for hypotension development during continuous albuterol administration in pediatric patients. ⋯ Diastolic hypotension is a common occurrence among patients who receive continuous albuterol nebulization for status asthmaticus. Total albuterol dose appeared to be directly related to risk of developing diastolic hypotension. Administration of supplemental fluid boluses before continuous nebulized albuterol appeared to provide a significant protective effect. The clinical impact and the significance of diastolic hypotension and the importance of prophylactic administration of intravenous fluid boluses in patients experiencing status asthmaticus are yet to be determined.

Bronchial thermoplasty (BT) is an emerging treatment modality for patients with difficult to treat asthma. It has been shown to be beneficial for symptom control and improves quality of life and reduces frequency of hospitalization. Safety data from the two major trials of BT indicate that patients who undergo these procedures are most likely to experience adverse respiratory events in the first six weeks post treatment. Lung abscess has never been reported as a direct complication of BT. In this case; we report a lung abscess as an immediate complication of BT, which we believe may be the first case. ⋯ It remains unclear why this patient developed a lung abscess so acutely post BT treatment. It is important that safety data continues to be collated and published as the procedure becomes more widely available with further long term follow-up in particular.
