User-Friendliness Evaluation of Handling pMDI with Various Add-on Devices in Asthmatic Patients
Bibliographic record
Abstract
The objective of this study was to assess the use of pMDI alone and pMDI with different spacers in asthmatic patients and to identify any associations between errors in handling the device for the first time and the sessions needed to reach the correct handling method, considering patient demographics and clinical characteristics. A total of 150 Asthmatic patients were crossed over to handle pMDI alone and with add-on inhalable devices (Aerochamber plus, Tips Haler, Able, Dispozable and Aer-8) randomly, without receiving verbal or demonstrative instruction (baseline assessment). The assessment of the inhaler technique was performed using checklists that had been set beforehand. Subsequently, the proper utilization of the inhaler was exhibited, and the patient's inhaler usage was reassessed. The demonstration was repeated until an optimal technique was attained. The number of counselling attempts required to achieve successful management, together with patient demographics and clinical factors, were documented. The mean percentage of total errors at baseline shows that pMDI alone is significantly higher than pMDI attached to add-on devices (53.90 ± 9.71, 32.54 ± 13.93, 24.53 ± 14.93, 21.6 ± 14.48, 25.14 ± 10.99, 27.47 ± 10.28) for pMDI alone, Aerochamber plus, Tips Haler, Able, Dispozable and Aer-8 respectively at p < 0.01. Able and Tips Haler spacers are significantly lower than other spacers with pMDI and pMDI alone in terms of total sessions needed to attain the complete optimal handling technique at p < 0.01. Weak and very weak correlations were observed between the percentage of total errors at baseline and the total sessions with education years, Montreal Cognitive Assessment, and age as well as some demographics and clinical variables. Handling pMDI can be challenging however the introduction of spacers simplifies this procedure. Different spacers cannot be treated as a homogeneous group due to variations in handling techniques and ease of use. the Able spacer requires the fewest handling steps of any spacer and has the highest percentage of patients who can use it without assistance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
