Following publication of the original article [1], the Authors identified errors in the COPD-related total costs for prompt and delayed initiators and the associated exponentiated coefficient (95% confidence interval) and p-value in Fig. 8b.

The corrected Fig. 8b is given below: 

These errors also impacted some statements under the “Results” and “Discussion” sections and “Conclusions”. This text has now been amended in this Correction.

Results

HCRU and costs following FF/UMEC/VI initiation.

The text in the penultimate sentence under the heading “HCRU and costs following FF/UMEC/VI initiation” in the “Results” section originally read: Prompt initiators had numerically lower all-cause total costs and significantly lower COPD-related costs per-person-per-year compared with delayed initiators (Fig. 8; COPD-related costs: prompt £742, delayed £801, p = 0.0016).

Corrected sentence: Prompt initiators had numerically lower all-cause total costs and similar COPD-related costs per-person-per-year compared with delayed initiators (Fig. 8).

Discussion

The first sentence of the second “Discussion” paragraph originally read: Prompt initiation of FF/UMEC/VI following the index exacerbation was also associated with fewer all-cause and COPD-related hospital readmissions at all time points assessed, as well as lower COPD-related total costs and COPD-related prescription costs compared with delayed initiation.

Corrected sentence: Prompt initiation of FF/UMEC/VI following the index exacerbation was also associated with fewer all-cause and COPD-related hospital readmissions at all time points assessed, as well as lower COPD-related prescription costs compared with delayed initiation.

Conclusions

Finally, an additional discrepancy in the “Conclusions” section is noted.

The first sentence originally read: Compared with delayed initiation, prompt initiation of FF/UMEC/VI following a moderate/severe exacerbation was associated with fewer subsequent exacerbations, fewer hospital readmissions, and lower COPD-related medical costs.

Corrected sentence: Compared with delayed initiation, prompt initiation of FF/UMEC/VI following a moderate/severe exacerbation was associated with fewer subsequent exacerbations, fewer hospital readmissions, and lower COPD-related prescription costs.

The Authors apologise for these discrepancies and for any inconvenience to the journal and to the readers.
