Introduction: Pressure injuries (PI) and diabetic ulcers (DU) are common wounds in home healthcare (HH) facilities with PI prevalence rate reaches up to 25%, and diabetic ulcers are difficult to heal, with potential complications of infections and/or amputations. Nonetheless, there is a lack of data on healing durations for which HH facilities can compare their cases healing trajectory to it. HH facilities, in recent year, have resorted to using digital wound care systems (DWCS) to support standardized documentation. In this study, we compared healing at HH that adopted DWCS between two years, looked at wounds that healed within three months versus those that needed more time, and reviewed size changes in wounds that were not healed yet but improved.  


Methods: This retrospective descriptive study used anonymous data from 50+ HH agencies using DWCS during 2022 and 2023. Analyses included healing duration over time and trends in wounds healing in < three months versus > three months ulcers. For non-healed but improved wounds, we assessed area reduction and the time to first measurable improvement. T-tests and ANOVA were applied.  


Results: The use of DWCS was linked to shorter healing times in both ulcers. For PIs, a total of 10,209 wounds were healed and the average healing time decreased from 79.6 - 50.3 days in 2022 vs 2023. Average healing of wounds that took > three months was 73.2 days. Further,  
non-healed but improved PIs showed a 25.4% faster reduction time. Larger PIs ( >4 cm²) showed greater reductions, with time to improvement decreasing by 35.5 days  
 
DUs showed similar results, with healing time decreasing from 98.9 to 68.1 days (p< 0.001). The proportion of healing within three months also rose by 5.3%. Area reduction and time to improvement improved as well, particularly for wounds over 2 cm².  


Discussion: Regular use of the DWCS was linked to faster healing and earlier signs of improvement in both PIs and DUs even among the larger wounds, which are the most difficult to handle. The results indicate that regular use of DWCS can support everyday care and track wound healing over time.
