Abstract |
Background |
The aim of this survey was to investigate variations of drugs for obstructive airway diseases delivery rates and refunds at a national level which are rarely reported.
Methods |
The French national health data system (56 million, 87% of the population) was used to identify insurance beneficiaries with at least one drug delivery (Anatomical Therapeutic Classification R03) per year between 2012 and 2017.
Results |
At least one drug delivery in 2017 was identified for 7.5 million people (12.9%). High proportions of people with at least one, two or three drug deliveries were observed between the ages of 0 to 2 years (22%, 10%, 5.5%), then decreased between the ages of 18 and 40 years (9.3%, 3.8%, 2.3%) and increased again in people 75 years and older (17.8%, 11.9% 9.9%), with strong variations between years. In 2017, the proportions of people with at least one delivery, either alone or in combination with other drugs, were 68% for inhaled corticosteroids (ICS) (median 1; IQR 1–4), 59% for short-acting beta2-agonists (SABA) (1; 1–3), 42% for long-acting beta2-agonists (LABA) (2; 1–6), 11% for leukotriene receptor antagonists (3; 1–9), and 12% for inhaled anti-cholinergics (4; 1–10). Younger patients more often received SABAs (0–2 years: 84%) and leukotriene receptor antagonists (3–6 years: 14%) and people 75 years and older more often received LABAs (59%) and ICS, either alone or in combination with other drugs (28%).The mean annual refund reimbursed per person decreased from €136 in 2012 to €118 in 2017.
Conclusion |
This study suggests a low level of use for drug classes associated with low delivery rates, suggesting inappropriate prescriptions and poor follow-up. These results highlight the difficulty of identifying these problems if delivery rates variations over several years are not taken into account.
