Impact of a Hospital Pharmacist's Intervention on FENO (Fractional Exhaled Nitric Oxide) in Asthmatic Patients

24. oktober 2017 opdateret af: Renaud Louis, University of Liege

Study of the Impact of a Hospital Pharmacist's Intervention in Collaboration With Pneumologists on Bronchial Inflammation of Outpatient Asthmatic Patients Seen in University Hospital of Liege

The impact of a pharmacist's intervention on asthma control has now been well demonstrated, but its effect on inflammatory markers of FENO (Fractional exhaled nitric oxide) in asthmatic patients has been little studied in the literature. The aim of this study is to investigate the impact of a pharmacist's intervention on FENO in patients seen in clinical practice by a pneumologist in a secondary university center.

Beskrivelse

Inclusion Criteria:

  • Adult asthmatics (definition of asthma: FEV1 [forced expiratory volume in 1 second] reversibility of at least 12% and 200 mL after 400 mcg of salbutamol and/or PC20M [provocative concentration of methacholine causing a 20% fall in FEV1]<16 mg/mL)
  • unchanged or increased dose of inhaled corticosteroids prescribed by the pneumologist at the visit
  • FENO (fractional exhaled nitric oxide) > or = 25 ppb

Exclusion Criteria:

  • Treatment with oral corticosteroids to treat an asthma exacerbation within 4 weeks before the visit with the pneumologist

Exclusion Criteria during the study:

  • Change of the dose of ICS (inhaled corticosteroids) during the follow-up of 3 months after the pharmacist's intervention
  • Severe asthma exacerbation requiring oral corticosteroids within the 4 weeks before the follow-up visit (3 months after the pharmacist's intervention)

Deltagergruppe / Arm
Intervention / Behandling
Andet: Intervention group
Asthmatic patients with the pharmacist's intervention

Pharmacist's intervention with asthmatic patients:

  • Detailed questionnaire on asthma and treatments (atopy, comorbidities, smoking status, asthma control, adverse effects of treatments, etc.)
  • Explanation of asthma and inflammation
  • Explanation of triggers and how to avoid it
  • Explanation of asthma treatments
  • Explanation of the inhalation technique with a physical demonstration
  • Emphasis on treatment adherence
  • Assessment of comorbidities and their treatment
  • Emphasis on influenza vaccination
Andet: Control group
Asthmatic patients without the pharmacist's intervention (only questionnaires)
- Detailed questionnaire on asthma and treatments (atopy, comorbidities, smoking status, asthma control, adverse effects of treatments, etc.)
