Factors related to poor asthma control in Latvian asthma patients between 2013 and 2015

Abstract

ObjectivesTo investigate whether beliefs about asthma medication, cognitive and emotional factors are related to poor asthma control in a sample of Latvian asthma patients in 2015.DesignCross-sectional, self-administered survey.SubjectsThree hundred and fifty two asthma patients (mean age 57.5 years) attending outpatient pulmonologist consultations in Riga, Latvia during September 2013 to December 2015. The sample size was calculated to detect a prevalence of poor asthma control of 50% with a margin of error of 5% and a power of 95%.Main outcome measuresThe validated Beliefs about Medication Questionnaire (BMQ) and the Brief Illness Perception Questionnaire (brief IPQ) were used. Good asthma control was assessed using the asthma control test (ACT), a validated five-item scale that reliably assesses asthma control over a recall period of four weeks. Logistic regression models were used to predict poor asthma control.ResultsPatients who had a good control of asthma medication (OR 0.70; 95% CI 0.61–0.79) or were confident that their asthma medication improves illness (OR 0.84; 95% CI 0.74–0.95) had a reduced risk of poor asthma control. The more symptoms (OR 1.63; 95% CI 1.44–1.84) the asthma patients perceived or the more their illness affects their life, the higher the probability of poor asthma control (OR 1.47; 95% CI 1.31–1.65). Some beliefs of necessity and concerns of asthma medication were also statistically significantly related to poor asthma control.ConclusionsBeliefs of necessity of asthma medication, cognitive and emotional illness perception factors correlate well with poor asthma control in Latvian patients.

The correlation between self-related adherence, asthma-related quality of life and control of asthma in adult patients

“…Therefore, outcomes assessment based on patient-oriented assessment has been widely recognised in the last decades. Compliance in medication, asthma control and quality of life (QoL) have emerged as vital outcomes for improving asthma management and communication tools between patients and their healthcare professionals [5][6][7][8].…”

Investigating the validity and reliability of the traditional checklist for assessment of specific inhalation techniques with pressurized metered-dose inhalers using the Aerosol Inhalation Monitor

“…An aerosol inhalation monitor (AIM) [21][22][23] quanti es key inhalation steps and identi es whether the actuation is coordinated with inspiration of MDIs, which can serve as an objective tool to assess inhalation techniques [24]. It can validly and reliably assess patient inhaler technique.…”

Conductas de adherencia al tratamiento y control del asma: El rol de la percepción del tratamiento

“…Siguiendo esta lógica, entonces se puede iden ficar en qué medida la percepción del tratamiento se asocia con la adherencia y el control de la enfermedad. Un modelo que apoya al entendimiento de este proceso es el Necessity-Concerns Framework (NCF; Horne, Weinman, & Hankins, 1999), el cual explica las conductas de adherencia en función de variables perceptuales, en este caso, la percepción de necesidad del tratamiento y la preocupación por efectos adversos del mismo; sin embargo, no se ha corroborado del todo el vínculo con el control de la enfermedad (Chapman et al, 2017;Kosse, Koster, Kaptein, de Vries, & Bouvy, 2019;Smits, Brigis, Pavare, Maurina, & Barengo, 2017).…”
