Following the publication of this article [1], the authors reported a number of errors which are given below.

The published article contained a discrepancy in Table 3 between the PDF and HTML versions of the article. In the PDF version Table 3 was missing a row as shown below:

Table 3

Data collected for process evaluation

Aspect of process evaluation	Data collection method	Data collected and data type
Delivery to the clusters	1. Collation of registers from QuIP meetings (30 meetings in total across 93 hospitals)2. Collation of VLE usage logs	1. Free text responses regarding the positive and negative aspects of the programme2. Observations and interviews with key staff in the 6 ethnographic sites
Delivery at the site level – QI intervention	1. Online exit questionnaire.	1. Whether a stakeholder meeting was held (QI strategy 1)2. run-charts were used (QI strategy 4)5. Whether the patient pathway was segmented (QI strategy 5)6. Whether the PDSA approach was used (QI strategy 6)
Response of the sites / individuals	1. Online exit questionnaire.2. Ethnographic data	1. Free text responses to 2 reflective questions:If you were to be involved in EPOCH again, a) ‘what would you continue doing’ and b) ‘what would you do differently’?2. Observations and interviews with key staff in the 6 ethnographic sites

Table 3 should in fact contain four rows as in the HTML version:

Furthermore, Fig. 4 was condensed upon submission, which resulted in half the data lines losing their legends in both the HTML and PDF version. Figure 4 originally appeared as follows:

Fig. 4

Clinical processes focussed on by hospital teams during EPOCH. Legend: CT, computer-aided tomography; WHO, World Health Organization; VTE, venous thrombo-embolism

The correct version of Fig. 4 is:

Fig. 4

Clinical processes focussed on by hospital teams during EPOCH. Legend: CT, computer-aided tomography; WHO, World Health Organization; VTE, venous thrombo-embolism

Furthermore, the names of several members of the EPOCH trial group were not processed correctly and should have been processed as follows (Given Name, Family Name):

Mike Bradburn

Fiona McMenemie

Jason Cupitt

Robert Thompson

Nick Harper

Simon Sleight

Belinda Cornforth
