Risk Factors Leading to Hospital Admission in Iranian Asthmatic Children

Abstract

Background: Asthma is one of the most common chronic diseases in the world, leading to an increased rate of hospitalization. We performed this study to better understand the factors leading to admission among asthmatic children. Methods: We performed a study among asthmatic children in a referral hospital for asthma and allergy in Tehran. Sixty-three cases were selected from asthmatic children admitted to the emergency room (ER) who still had an indication for ward or intensive care unit admission after primary treatment. Our control group was the asthmatic children discharged after primary treatment and patients who were referred to the asthma and allergy clinic (63 patients). Data were obtained by structured questionnaires filled out during clinical interviews. Results: There was a significant difference in mean age (5 years for cases vs. 6 years for controls; p = 0.049), personal and familial allergic history (69.8 and 57.1% for cases vs. 34.9 and 36.5% for controls; p < 0.01 and p = 0.02, respectively), history of recent respiratory infections (79.4% for cases vs. 49.2% for controls; p < 0.01), hospitalization history due to asthma (57.1% for cases vs. 23.8% for controls; p < 0.01) and regular use of inhaled corticosteroid (66.7% for cases vs. 33.3% for controls; p < 0.01). Conclusions: Our findings confirm most previous observations, suggesting that recent respiratory infections, hospitalization, personal or familial allergy, disease severity and lower ages are important factors leading to hospitalization. We also found that regular clinical follow-up, regular use of inhaled corticosteroids, higher IgE levels and O₂ saturation may lower the probability of hospitalization during asthmatic attacks.

Predicting frequent emergency department use among children with epilepsy: A retrospective cohort study using electronic health data from 2 centers

“…Several patient characteristics can predict patterns of care by people with chronic disease, including prior health care utilization, 14,22 demographics, 23 comorbidities, 24 insurance status, 22 family history, 25 social history, 24 medication history, 26 laboratory values, 26 vital signs, 26 disease control, 25 use of specialty care, 27 and patient engagement (ie, missed appointments). 24 For people with epilepsy, several factors are associated with frequent ED use, including care delivery factors (visiting a "low SES clinic"), 11 individual factors (lower knowledge, stigma, and suboptimal self-management), and epilepsy factors (frequent seizures).…”

Prevalence of asthma among Middle Eastern children: A systematic review

“…The disease can impede the academic development and social activities of the children. Children’s asthma is a burden on the health care system due to successive referral to practitioner and hospital which costs a lot (14,15). Due to the lack of a standard method for asthma diagnosis, examining the prevalence of asthma over time (16) was difficult.…”
