Insights
This study analyzed allergy/immunology (A/I) inpatient consultations from 1987-2001. Adverse drug reactions and asthma were most common, while immunodeficiency and anaphylaxis referrals remained stable, guiding A/I fellowship training.
Area of Science:
- Medical Specialties
- Clinical Immunology
- Allergy Medicine
Background:
- Limited research exists on referral patterns for allergy/immunology (A/I) inpatient consultations.
- Understanding these patterns is crucial for optimizing A/I fellowship training and patient care.
Purpose of the Study:
- To investigate the primary reasons for A/I inpatient consultations.
- To analyze trends in A/I consultations over a 15-year period.
- To inform and improve A/I fellowship educational curricula.
Main Methods:
- Retrospective chart review of all A/I inpatient consults from July 1, 1987, to June 30, 2001.
- Analysis of primary reasons for consultation.
- Comparison of A/I consultation trends with total hospital admissions and average daily patient load.
Main Results:
- Adverse drug reactions (36%) were the most frequent reason for A/I consults, followed by asthma (21%) and miscellaneous reasons (21%).
- Referrals for immunodeficiency (8%) and anaphylaxis (6%) remained stable over the study period.
- A decrease in asthma and adverse drug reaction consults was observed, correlating with a fall in total hospital admissions, though the ratio of A/I consults to average daily patient load increased.
Conclusions:
- Identifying common consultation reasons aids in educating A/I fellows and residents.
- Inpatient consultations are vital for A/I training, offering opportunities to manage severe, life-threatening conditions.
- Stable consultation trends for immunodeficiency and anaphylaxis highlight the allergist/immunologist's essential role in inpatient care.
Background:
Few studies examine the referral patterns for allergy/immunology (A/I) inpatient consultation.
Objective:
The purpose of this study was to examine the primary reason and trends for A/I inpatient consultation to improve fellowship training.
Methods:
We performed a retrospective chart review of all inpatient A/I consults from July 1, 1987 to June 30, 2001 to determine the primary reason for consultation. We also reviewed trends in the total admissions and the average daily patient load compared with A/I consultation.
Results:
A total of 1,284 A/I inpatient consults were reviewed. Thirty-six percent (460 of 1,284) of inpatient consults were for evaluation of adverse drug reactions, 21% (270 of 1,284) asthma, 21% (272 of 1,284) miscellaneous reasons, 8% (109 of 1,284) possible immunodeficiency, 7% (93 of 1,284) angioedema/urticaria, and 6% (80 of 1,284) anaphylaxis. Our results demonstrated a fall in inpatient consults that correlated with a similar fall in total hospital admissions. The ratio of A/I inpatient consults to total admissions remained constant. Additionally, the ratio of A/I consults to average daily patient load increased over the study period. There was a decrease in asthma and adverse drug reaction consults, whereas immunodeficiency and anaphylaxis referrals remained stable.
Conclusions:
Identifying the most common reasons for inpatient consultation provides a guide for the education of A/I fellows and primary care residents. Inpatient consultation continues to play a crucial role in A/I training as it provides unique opportunities to evaluate serious life threatening diseases. An unchanged trend of consultation for immunodeficiency and anaphylaxis reaffirms the importance of the allergist/immunologist as a valuable resource for inpatient consultation.
