The primary health outcomes used in the analysis were observations of new ulcers, deaths and ulcer-free discharges. The measure of days of ulcer free survival was derived from these observed endpoints. The average age of the patients was reported to be approximately the same in the control group and in the intervention group (79.9 and 77.7 respectively). The ulcer risk (Norton score) indicated a greater proportion of high-risk patients in the intervention group, but the difference was not statistically significant (p=0.08). The intervention group contained a greater proportion of males (80%) than the comparison group (less than 50%), and patients in the former group had relatively more chronic conditions than patients in the comparison group.
