Risk factors for readmission to hospital for asthma in childhood.

摘要: BACKGROUND--Readmissions account for part of the increase in hospital admissions asthma childhood seen many countries. METHODS--This observational study recorded demographic features and severity, treatment management 1034 individual children admitted to over a one year period, followed maximum 33 months. RESULTS--Readmissions were common, with 33% readmitted by six months 51% two years. After controlling wide range variables, factors that significantly increased readmission were: female sex (relative risk (RR) 1.23; 95% confidence interval (CI) 1.03 1.46), young age (age < 5 years RR 1.71; CI 1.41 2.08), number previous (one admission 1.32; two, 1.68; three, 2.00; four or more, 2.80), inpatient intravenous (RR 1.29; 1.08 1.55). Inpatient theophylline was used frequently (98.4%), but associated decreased readmissions 0.51, 0.28 0.92). Factors which did not predict included ethnicity, respiratory pulse rate, medical team, prescribed prophylactic treatment, type follow up, use action plans. CONCLUSIONS--Risk relate characteristics sex), severity condition (intravenous treatment), may reflect behaviour illness. Medical influence readmissions. Strategies reduce high rate need be developed.
