Haroon Rashid, Fatima Zafar, Nida Arif

Introduction: Asthma is a serious global health problem. The prevalence of asthma is increasing in most countries, especially among children. The burden of asthma is experienced not only in terms of healthcare costs but also as lost productivity. Objectives of the study: The main objective of the study is to analyze different predictors for acute asthma attack in asthmatic patients. Material and methods: This cross sectional study was conducted in Bahawalpur Victoria Hospital, Bahawalpur during January 2019 to August 2019. In this study we studied one hundred patients who were referred with exacerbation of asthma or other acute asthmatic symptoms and went under treatment in hospitals. Pulse Oximetry was done and documented at arrival and 30, 60, 120 minutes after arrival. PImax and PEmax were measured and documented at arrival and 60, 120 minutes after arrival. Results: Detailed frequencies of exposures in patients both with and without hospital admissions due to asthma exacerbations in the year following admission to the study are shown in Table 1. The majority of these associations are self-explanatory; however, some deserve special attention. Ratio of FEV1/FVC, PEF, PImax, PEmax and FVC with cut-off point 50.4, 2.05, 62.5, 63.5 and 2.7 with 70% sensitivity were capable to forecast the need for hospitalization. Conclusion: It is concluded that FEV1 and PEF that have role in admission criteria, FEV1/FVC at arrival to ED and PEmax after an hour after treatment can also be used to forecast the need for admission.
