Abstract
Aim
To investigate the inter and intra reliability of using 3D imaging to measure wounds.
Method
20 wound models of 4 different shaped wounds in 5 different colours were created from plastic mouldable beads. 3D images were taken using the BlasterX Senz3D camera and measured using the GPC Wound Measure application (version 3.15.0.0, UK). Intra-user reliability was determined comparing 20 wound measurements of each wound model. Inter-user reliability was determined by 5 different clinicians photographing each model and independently measuring each wound photo. The inter- and intra-rater measurements for wound surface area and volume were compared using the ICC and differences from the overall mean plotted on Bland-Altman graphs.
Results
The interclass co-efficient (ICC) for inter-rater reliability in measuring surface area was 0.958 (95% CI 0.919-0.981, p < 0.005). The intra-rater reliability when measuring wound surface area was 0.996 (95% CI 0.993-0.998, p < 0.005). For wound volume, the ICC for inter-rater reliability was 0.925 (95% CI 0.857-0.967, p < 0.005) and 0.999 (95% CI 0.998-0.999, p < 0.005) for intra-user reliability. 5.5% of measurements were outside 2 SD of the mean for wound volume.
Conclusions
3D imaging offers a quick, reliable, and easy to use solution to measuring wounds. We have shown it is a reliable and reproducible method of measuring wounds between different clinicians.

Abstract
Abstract
Aim
The purpose of this mixed methods feasibility study was to assess the feasibility of delivering ESWT to patients with DFUs. It also aimed to explore any potential clinical effect of ESWT on wound healing and investigate whether ESWT may offer any patient reported benefits.
Method
A single centre mixed methods feasibility study. Patients with a DFU who met the eligibility criteria underwent ESWT 3 times in over 7 days. Primary outcome was feasibility of delivering the intervention. Secondary outcomes included wound size, number of DFU healed at 12 weeks and quality of life. Semi-structured interviews explored participants experience of undergoing ESWT.
Results
22.6% (24/106) of patients screened were recruited. The mean attendance to clinic was 90.9% and 65.1% to follow up. The mean score for acceptability and tolerability was 9.86 (SD 0.48, 95% CI 9.62-10.01) and 9.15 (SD 2.57, 95% CI 7.87-10.42) respectively. There were no serious adverse events or side effects. 45.5% of DFU healed during follow up and quality of life scores improved until 8 weeks. Key themes identified from the qualitative interviews were desire for the fast healing, improved quality of life, new treatments must be flexible and accessible on transport.
Conclusions
This study has shown it is possible to recruit and retain patents into this research. This study supports development of a large randomised control trial to determine the clinical and cost effectiveness of ESWT for DFU healing.
