ABSTRACT
BACKGROUND: Although the clinical practice guidelines recommend continuous adjustment of asthma treatment and reducing the maintenance drugs when achieving control (step-down), there are few studies of standard clinical practice aimed at collecting information on the factors that determine step-down failure. OBJECTIVE: To determine the factors that determine step-down failure in standard clinical practice of patients with moderate-severe asthma controlled by a combination of inhaled glucocorticoids and long-acting beta agonists. METHODS: A multicentre retrospective study included 374 patients with moderate-severe asthma controlled with inhaled glucocorticoids and long-acting beta agonists for whom the physician indicated a step-down in 2016. RESULTS: The step-down failed in 41.7% of the patients. The following factors were related to failure: greater patient age (P=.006), presence of at least 2 comorbidities (P=.016), greater severity level (severe persistent vs. moderate persistent) (P<.001), greater age at diagnosis (>40 years) (P=.045), the higher the therapeutic step before (P=.003) and after the change (P<.001), the shorter the time of improvement/control prior to the change (P=.019), lower FEV1 (P=.001) and a poorer Asthma Control Test score or Asthma Control Questionnaire score before the step-down (P<.001). The logistic regression analysis showed a higher probability of step-down failure in the more elderly patients (OR, 0.983; 95% CI 0.969-0.997) and those with severe asthma compared to those with moderate asthma (OR, 0.537; 95% CI 0.292-0.985), as well as an increased probability of success if the patients had the disease controlled for more than 6 months (OR, 2.253; 95% CI 1.235-4.112). CONCLUSION: In standard clinical practice conditions, step-down fails in a high percentage of patients, and the suggestion is to indicate step-down when the patient has had more than 6 months of disease control.
ABSTRACT
La economía informal se debe diferenciar de conceptos tales como empleo informal y sector informal, cada uno con sus propias características. Existen varios tipos de trabajadores informales que se agrupan en varias categorías según su labor. Los familiares de estos trabajadores se agrupan dentro del empleo vulnerable, que no se benefician tampoco de coberturas sanitarias. El empleo informal condiciona una gran morbimortalidad que se traduce en pérdidas económicas y gran número de años de vida perdidos por discapacidad, especialmente entre poblaciones jóvenes y mujeres. Son necesarias políticas sanitarias encaminadas a disminuir las desigualdades socioeconómicas, mejorando la capacitación de profesionales sanitarios y la accesibilidad a los servicios sanitarios de estos trabajadores
Informal economy must be differentiated from concepts such as informal employment and the informal sector, each with its own characteristics. There are several types of informal workers that are grouped into several categories according to their work. The families of these workers are grouped into vulnerable job, which is also not beneficial for health coverage. Informal working conditions mean great morbidity resulting in economic losses and a large number of quality-adjusted life year, especially among young populations and women. Health policies are needed to reduce socio-economic inequalities, improve the training of health professionals and the accessibility of health services to these workers
