RATIONALE: The National Hospital Discharge Survey Database for the years 1995 to 2002 showed decreases in both asthma hospitalization and mortality rates during the study period. The purpose of our study was to examine the primary reason and trends for A/I inpatient consultation especially for asthma at Washington University in St. Louis School of Medicine during the past ten years. METHODS: We performed a retrospective chart review of all inpatient A/I consults from 1/19/94 to 8/11/05 to determine the primary reason for consultation and frequencies of different consults were recorded. RESULTS: A total of 1,238 A/I inpatient consults were reviewed. Patient ages ranged from 18-93 years and 62% of consults were for women and 38% were for men. During the past ten years, the total number of consults has declined. Asthma consults peaked in 1998 with seventeen consults and decreased to fewer than two consults per year since 2001. Consults for Allergic Bronchopulmonary Aspergillosis (ABPA) have also decreased; no consults were called in the last two years. Penicillin allergy was the most common reason for consult every year. Cephalosporin and sulfa allergy consults were the second and third most common allergy consults respectively. Consults for rash peaked in 1998-2000 and have subsequently decreased. Immunodeficiency and anaphylaxis consults were consistently rare. CONCLUSIONS: At our institution, we have found that the total numbers of allergy and immunology consults have declined in the past ten years especially for asthma. This may be largely due to better outpatient care of asthmatics with potent inhaled steroids.
