The Burden of Short-Acting β₂-Agonist Use in Asthma: Is There an Italian Case? An Update from SABINA Program.

ABSTRACT:

Introduction

Preliminary results from the SABINA (SABA use IN Asthma) program showed lower overuse of short-acting β₂-agonist (SABA) in Italy compared to other European countries. The aim of the present study was to ascertain whether SABINA's results might have been affected by the Italian National Health System and pharmaceutical market dynamics, by examining patients' characteristics in relation to SABA prescription/purchase habits.

Methods

Multiple approaches were used: (1) a retrospective study using the General Practitioners' (GPs) Italian IQVIA Longitudinal Patient Database (LPD) to assess SABA overuse (more than two canisters/year) and its association with exacerbation risk; (2) a survey conducted across 200 Italian pharmacies to calculate the proportions of SABA purchases without a prescription; (3) a cross-sectional study on the specialists' IQVIA Patient Analyzer database to understand the SABA prescription habits of specialists.

Results

Among SABA users identified through IQVIA LPD, the proportion of patients having more than two SABA canisters/year was 32%. Overall, patients prescribed more than two SABA canisters/year by GPs had 30% higher risk of exacerbations than patients with a maximum of two SABA canisters/year. The joint evaluation of IQVIA LPD and survey's findings revealed that IQVIA LPD tracks three out of four SABA canisters dispensed. The survey showed that, on average, SABA users purchased four canisters/year. Patients prescribed SABA by specialists were more frequently men, younger, thinner, and had higher spirometry values.

Conclusion

SABA overuse is common in Italy, with a share of consumption not regulated by medical prescriptions. Because SABA overuse increases exacerbation risk, changes to national guidelines should be encouraged to ensure implementation of global recommendations.

Project description:BackgroundOver-reliance on short-acting β2-agonists (SABAs) is associated with poor asthma outcomes. However, the extent of SABA use in Turkey is unclear owing to a lack of comprehensive healthcare databases. Here, we describe the demographics, disease characteristics and treatment patterns from the Turkish cohort of the SABA use IN Asthma (SABINA) III study.MethodsThis observational, cross-sectional study included patients aged ≥ 12 years with asthma from 24 centres across Turkey. Data on sociodemographics, disease characteristics and asthma treatments were collected using electronic case report forms. Patients were classified by investigator-defined asthma severity (guided by the 2017 Global Initiative for Asthma [GINA]) and practice type (primary/specialist care). The primary objective was to describe SABA prescription patterns in the 12 months prior to the study visit.ResultsOverall, 579 patients were included (mean age [standard deviation; SD]: 47.4 [16.1] years; 74.3% female), all of whom were treated by specialists. Most patients had moderate-to-severe asthma (82.7%, GINA steps 3-5), were overweight or obese (70.5%), had high school or university/post-graduate education (51.8%) and reported fully reimbursed healthcare (97.1%). The mean (SD) asthma duration was 12.0 (9.9) years. Asthma was partly controlled/uncontrolled in 56.3% of patients, and 46.5% experienced ≥ 1 severe exacerbation in the preceding 12 months. Overall, 23.9% of patients were prescribed ≥ 3 SABA canisters in the previous 12 months (considered over-prescription); 42.9% received no SABA prescriptions. As few patients had mild asthma, only 5.7% were prescribed SABA monotherapy. Therefore, most patients (61.5%) were prescribed SABA in addition to maintenance therapy, with 42.8% receiving ≥ 3 SABA canisters in the previous 12 months. Inhaled corticosteroids (ICS), ICS + a long-acting β-agonist fixed-dose combination and oral corticosteroids were prescribed to 14.5%, 88.3% and 28.5% of all patients, respectively. Additionally, 10.2% of patients purchased SABA over the counter, of whom 27.1% purchased ≥ 3 canisters in the preceding 12 months.ConclusionsDespite all patients being treated by specialists and most receiving fully reimbursed healthcare, nearly a quarter of patients received prescriptions for ≥ 3 SABA canisters in the previous 12 months. This highlights a public health concern and emphasizes the need to align clinical practices with the latest evidence-based recommendations.

Project description:ObjectivesThe SABINA CHINA study aimed to determine prescription data for asthma medication with a focus on SABA and ICS in a representative population of patients with asthma in China.MethodsSABINA China was a multicentre, observational, cross-sectional study with data collected retrospectively from a convenience sample of 25 tertiary centres across China. Patients (age ⩾ 12 years) with ⩾3 consultations/year were enrolled. Data were collected on clinical characteristics, asthma severity, and symptom control (as per GINA 2017), treatment and history of severe exacerbations over the past year. SABA over-prescription was defined as ⩾3 SABA canisters/year. Descriptive statistics are presented.ResultsBetween March and August 2020, 498 patients were included in the outcome analysis. Mean (SD) age was 48.7 (15.0) years, 57.9% were female and 91% had moderate-to-severe asthma (n = 453). Overall, 12.5% (n = 62) and 26.4% (n = 131) of patients had uncontrolled and partly controlled asthma, respectively. SABA add-on was prescribed to 20.3% (n = 101) of patients; one patient with moderate-to-severe asthma was prescribed SABA-alone. SABA over-prescription in the overall population was 4.0% (n = 20; all with moderate-to-severe asthma) and 19.8% (20/101) among those prescribed SABA add-on. In the mild asthma group, 50% (n = 22) were prescribed ICS/LABA and 43.2% (n = 19) were prescribed LTRA. Among those with moderate-to-severe asthma, 97.4% (n = 441) were prescribed ICS/LABA and 55.0% (n = 249) were prescribed LTRA. Approximately 30% of patients (n = 149) experienced ⩾1% and 6.6% (n = 33) ⩾3 severe exacerbations in the preceding year; mean annual number of severe exacerbation/patient was 0.6 (1.2). Among those prescribed SABA add-on, ICS/LABA and LTRA (non-mutually exclusive groups due to overlapping prescriptions), 54.5%, 29.9%, and 35.3% had ⩾1 severe exacerbations, respectively.ConclusionAmong patients with predominantly moderate-to-severe asthma managed in tertiary care and were prescribed SABA, 1 in 5 received ⩾3 canisters/year. Fewer patients who received ICS/LABA prescriptions experienced annual exacerbations than those prescribed SABA add-on.
