Uncontrolled Asthma in Primary Care: Implementation and Practical Use of ReferID

Abstract

Introduction: real-life evidence shows deficiencies in achieving asthma control goals, with high use of short-acting beta-2 agonists (SABA) and overuse of systemic corticosteroids (SC). Methods: observational, descriptive study, applying the ReferID tool with 4 questions to identify patients with uncontrolled asthma and/or at risk of severe crisis: in the last 12 months [1] Have you received ≥2 cycles of CS and/or used them as maintenance therapy?; [2] Have you had ≥2 emergency visits for asthma?; [3] Have you ever been intubated or admitted to the Intensive Care Unit (ICU) for asthma?; [4] How many SABA inhalers have you used? An affirmative answer to questions 1, 2 or 3, or using ≥3 canisters of SABA, suggests risk of severe attack, need for CS and/or life-threatening risk. In these patients, evaluation by specialists is recommended. Results: 441 patients from 7 institutions in the Metropolitan Area of Buenos Aires were enrolled. An evaluation by specialists was recommended for 60.1% (95% confidence interval [95%CI]: 55.5%-64.7%); 33.8% (95%CI:29.39%-38.21%) received ≥2 cycles of CS and/or used them as maintenance; 36.1% (95%CI:31.62%-40.58%) attended ≥2 times to the emergency department; 41.5% (95%CI:30.06%-38.94%) used ≥3 containers of SABA; 8.8% (95%CI:6.16%-11.44%) had a history of intubation or ICU admission; 37.2% were assisted in public institutions, with significantly higher severity indicators than in private ones. Conclusions: Refer ID is a simple, useful tool to quickly identify asthma patients who are at risk of severe exacerbations and/or may have a diagnosis of severe asthma and would benefit from evaluation by a specialist.
