Assessment of 105 Patients with Angiotensin Converting Enzyme-Inhibitor Induced Angioedema

Table 3

Data regarding hospital admissions and Emergency Department visits. Data was unknown regarding admissions in two patients. Three patients were admitted, but the number of admissions was unknown. Thus, they count as one admission each, even though some might have been admitted more than once; therefore, the number of hospitalizations is an approximated minimum. In five patients, the duration of admission was unknown. Diagnostic codes are from the International Classification of Diseases, Tenth Edition (ICD-10).
