Investigate Hospitalized Exacerbation Of Bronchial Asthma

Objective: To look for factors in reducing hospitalization and provide theory for clinical prevention, analyze the characteristics of patients with bronchial asthma.Methods: 168 patients with asthma, from the First Affiliated Hospital of Chongqing Medical University, were studied retrospectively from January 2006 to December 2008. It was reviewed that: (1)general situation: age, gender, number of previous hospitalization, course of disease, allergic history; (2) medical care before admission ; (3)details of the current episode of asthma;(4)the situation after hospital admission.Results:(1)General situation: In 168 patients with asthma, there are 103 female patients and 65 male patients. The patients had a average age of 52.6 years old from 20 to 87 years. 168 patients (82.1%) had been suffered from asthma for more than 3 years. 124 patients (73.8%) had received in-patient treatment.50 patients(29.8%) had a clear history of allergy.(2)Medical care before admission: 133 patients(79.2%) received medical care for asthma before hospital admission. Only 8 patients(4.8%) used inhaled corticosteroid(ICS) and only 11 patients(6.5%) used ICS+LABA. 137 patients(81.5%) did not take medicine regularly.(3)Details of the current episode of asthma: 156 cases (92.9%) had a clear risk factor, and 117 patients (75.0%) were suffered from respiratory tract infections. The average time in seeking medical care was 17.2 hours. 136 patients(80.1%) took acting beta-2 agonist and 25 patients (14.9%) did not take medicine before hospital admission.(4)The situation after hospital admission: The patients had an average cost of 5449.0 yuan, stayed in hospital from 1 day to 37 days. The following were considered as possibly preventable factors:①inappropriate preventive treatment(20.8%),②poor compliance(81.5%),③in touch with allergen (22.6%),④suffered from respiratory tract infections (69.6%),⑤not using medicine before the current episode of asthma (14.9%),⑥delay in seeking medical care(19.6%). 97.1% of the patients had at 1east one preventable factor and 75 9% had three or more factors.Conclusions: 1.The constituent ratio with disease in female was higher; 2.The majority of patients had received in-patient treatment; 3.The majority of patients with asthma received a medicine care before hospital admission ; 4.Poor compliance is the considerable causing of asthma; 5.Respiratory infections are the most important predisposing factor that leads to and induces bronchial asthma; 6.Patients were expected to take corresponding measures to reduce the number of future admissions.
