Sustainable Inhaler Prescribing in Intermediate Care Units (INHAVERD)
Potential of Intermediate Care Units to Reduce Environmental Impact Through Sustainable Inhaler Prescribing: a Quasi-experimental Study of a Multidisciplinary Clinical Intervention
The goal of this clinical trial is to learn if a multidisciplinary review of inhaler treatment can increase the use of inhalers with a lower environmental impact in adults admitted to intermediate care units who use inhalers. The main questions it aims to answer are:
- Does the intervention change the percentage of each type of inhaler prescribed (pressurized metered-dose inhalers, dry powder inhalers, and soft mist inhalers) between admission and discharge?
- Does the intervention improve treatment adherence and inhaler technique, reduce the use of rescue inhalers, and reduce carbon dioxide (CO2) emissions? Researchers will compare patients cared for by physicians who apply the intervention with patients cared for by physicians who do not yet apply it, to see if more patients switch to inhalers with a lower environmental impact.
Participants will:
- Have their inhaler prescription reviewed by a physician, who may change it when clinically appropriate, taking environmental impact into account
- Have their adherence and inhaler technique assessed by a healthcare professional
- Receive individual education on how to use their inhalers, if needed

Gedetailleerde beschrijving
The health sector generates about 5% of global greenhouse gas emissions, and pressurized metered-dose inhalers (pMDIs), which contain propellants with a high global warming potential, are a relevant part of this footprint. Dry powder inhalers (DPIs) and soft mist inhalers (SMIs) are more sustainable alternatives. In 2025, the Spanish Ministry of Health issued recommendations on sustainable inhaler prescribing that include reviewing the indication, optimizing inhaler technique and adherence, and switching to lower-impact devices when appropriate.
This quasi-experimental study with two arms and stepped implementation over three periods will be conducted in the intermediate care units of Hospital Sant Antoni Abat. Allocation is determined by the treating geriatrician: patients of two of the four geriatricians form group 1 and those of the other two form group 2. In period 1 (3 months, retrospective data), neither group receives the intervention; in period 2 (about 6 months), only group 2 receives it; in period 3 (about 3 months), both groups receive it.
The intervention, delivered within one week of inclusion, consists of: (1) a physician review of the inhaled therapy prescription in the electronic prescription system, with changes if needed, also considering environmental criteria; (2) assessment of adherence with the Test of Adherence to Inhalers (TAI), classifying adherence (good, intermediate, poor) and type of non-adherence (erratic, deliberate, unwitting); (3) assessment of inhaler technique with device-specific checklists (GINA, UK Inhaler Group); and (4) individualized education and, if the device is not suitable or rescue inhaler use is excessive, a switch to a lower-impact inhaler.
The primary analysis will compare, in period 2, the percentage of prescriptions of each inhaler type at admission and at discharge. Assuming a switch from pMDI to DPI in 5% of the control group and 20% of the intervention group, 50 patients per group are needed for period 2 (two-sided alpha 0.05, power above 80%), with an expected 10% loss to follow-up. CO2 emissions will be estimated from the Spanish database on the environmental impact of inhalers. Analysts will be blinded to the study period.

Ander: delayed intervention
Patients of two geriatricians; usual care in periods 1 and 2, multidisciplinary inhaler intervention in period 3 |
Within one week of admision, a physician reviews the inhaled therapy prescription (indication, duration) and changes it if needed, also considering environmental impact. A healthcare professional assesses adherence with the Test of Adherence to Inhalers (TAI) and inhaler technique with device-specific checklists (GINA, UK Inhaler Group), and provides individualized education. If the device is not suitable or rescue inhaler use is excessive, the physician considers switching to a lower-impact inhaler (dry powder or soft mist inhaler). |
