| Abstract |
Up to 70-80% of patients use inhalers incorrectly. Dry-powder inhalers (DPIs) require forceful inhalation for optimal delivery, and approximately 40% of Global Initiative for Asthma (GINA)-defined Step-3+ patients inhale corticosteroid and long-acting beta-agonist through DPIs. The CRITIKAL study (Price et al. in J Allergy Clin Immunol Pract 5:1071-e9-1081-e9, 2017) found a statistically significant association between 'insufficient inspiratory effort' error and increased risk of uncontrolled asthma and hospitalisation-requiring exacerbations. This paper explores the cost-effectiveness of an error-targeted intervention. A probabilistic Markov cost-utility model simulated patients transitioning between controlled and uncontrolled health states over one year. Odds ratios (ORs, from the CRITIKAL study) of a patient having uncontrolled asthma conditional on making the error were applied to baseline transition probabilities sourced from the literature, both indirectly via an adjustment formula (Zhang et al. in JAMA 280:1690-1691, 1998) and directly by assuming OR approximates relative risk (RR). The analysis explored complete/partial eradication of the error when the intervention was priced to match comparators, as well as impact of indirect costs based on lost/reduced productivity. The intervention dominated both DPI comparators over one year, with direct cost savings of £45/£86 with 0.0053/0.0102 additional quality-adjusted life years (QALYs), and had the highest probability of being cost-effective at a £20,000/QALY threshold. Key factors driving variance were weekly utilities per state and RR of moving to an uncontrolled state. The analysis demonstrated the economic and societal costs of 'insufficient inspiratory effort' and potential economic benefits of introducing an effective intervention to reduce/eradicate this error. Further research should assess the economic impact of other handling errors. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 November 2018.
All research outputs
#17,292,294
of 25,382,440 outputs
Outputs from HEPAC Health Economics in Prevention and Care
#919
of 1,303 outputs
Outputs of similar age
#219,215
of 339,299 outputs
Outputs of similar age from HEPAC Health Economics in Prevention and Care
#11
of 19 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,303 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.7. This one is in the 22nd percentile – i.e., 22% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 339,299 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 19 others from the same source and published within six weeks on either side of this one. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
