Abstract
Introduction: In Mexico it is one of the 10 leading causes of utilization of health services it is estimated that more than 5 million Mexicans suffer from asthma 20.
OBJECTIVE: Analyze exacerbations and associated factors that can help to identify patients at high risk.
METHODS: Retrospective clinical essay of patients aged 1 to 15 years treated at the emergency department of pediatric pulmonology, diagnosed with asthma exacerbations and requiring hospitalization. Demographic, physical, birth related background, respiratory disease severity, exacerbation severity and socioeconomic factors, level of asthma control were described.
RESULTS: 271 patients were reviewed (September 2013 to December 2014), the male dominance 1.25: 1, a median age of 8 years, history of atopy was 72%.The variables that showed an inverse correlation were: time tracking INER (0.007, -0.28 Coef, OR 0.74.), Correct technique of using inhaled medication (0.04, -0.98 Coef, OR 0.37.).In 142 patients (52%) didn´t use salbutamol for treatment of early symptoms of exacerbation. Only 26% were compliance with treatment, and only 28% used properly the inhalation device. Correlations with the primary outcome (exacerbation) the most significant correlation was adherence to treatment (Coef. -0.11), Correct technique in use inhaled medication (Coef. -0.14).
CONCLUSIONS: The most common comorbidity was allergic rhinitis in 83% of cases. Of patients with allergic rhinitis, only 4.4% had treatment.Although only the Moderate-Severe Persistent stadium showed a statistically significant but weak correlation for asthma exacerbations.
