I was glad to read in the contribution of Arora et al.1 that they found that the inter-rater and intra-rater reliability of measuring wound undermining in people with spinal cord injury was 0.996 and 0.998 with a percent close agreement >90% when the undermining measures >0.5 cm. These findings support the results of similar research we published in 1997 and 1998.2, 3 Our conclusions escaped international attention, probably because they were only published in Dutch. Based on this research, we designed a local wound measurement protocol in which length, width, depth and the greatest undermining were rounded up to 0.5 cm and registered in a graph weekly. Since that time this protocol (working name ‘Decu-stick’ protocol) has been in use for in-patients and out-patients in the spinal unit in Utrecht and several other units in the Netherlands. Data collected in this way gave us the opportunity to design an algorithm for the prediction of wound healing. Details of this way of wound measurement and wound-healing prediction were published in this journal in 2015.4 The use of plain sterile swabs instead of specially designed Decu-sticks is now being tested. An application for digital registration is under construction following the Standards of the International Spinal Cord Injury Skin and Thermoregulation Function Basic Data Set.5 Interested clinicians and researchers are advised to visit the instruction website www.decu-stick.org (English version available) for further information.
