Relationship between Characteristics of the Wound and Healing Duration among Patients Treated during Home-Visits

In humans, wound healing is a vital but complex process governed by chronological yet overlapping stages, such as hemostasis, inflammation, proliferation, and remodeling. Because of the complexities of wound healing, it is prone to pausing at multiple levels. Wound healing can potentially be influenced by factors that affect cellular functions and physiologic responses. This research aimed to investigate the relationship between wound healing duration and demographic properties and characteristics of wounds among patients treated during home visits in Erbil, Iraq. To this end, a longitudinal correlational quantitative design was employed in the current study. A random sample of about 101 chronic wounds was found in 77 patients of both genders selected from all ages during home visits for around four years in Erbil. The professional nurse applied nursing management according to the nursing plan during home visits until the wound recovered. The total duration of wound healing was calculated and documented for each wound. Seventy-seven patients participated in the current study, with their mean±SD age being 58.02±16.29 years, ranging from 19 to 89. The median age was 60. More than half of the sample (54.5%) were ≥60 years, and 62.3% were males. Less than one-third of patients (31.2%) were of normal weight, 93.5% were married, 37.7% were housewives, and 35.1% were illiterate. Regarding the duration of wound healing, in more than one quarter (26.7%), it was delayed (took more than three months for healing). The longest mean healing time (20.06 weeks) was for pressure ulcers (P<0.001), which was significantly higher than all the mean healing times of other types of wounds. The study showed a significant (P=0.011) association between the mean healing time and the anatomic location of wounds, revealing that the highest mean healing time was for wounds located in the trochanteric area (21.10 weeks) or the sacrum (18.25 weeks). A significant association (P=0.002) was also detected between the mean healing time and the edge of the wound, with the highest mean healing time (18.64 weeks) found in wounds with undermined edges. Furthermore, the mean healing time was significantly higher among those with infected wounds (14.59 weeks) than the mean (6.50 weeks) among those with no infection (P<0.001). In conclusion, wound healing progression is an important but complicated process that healthcare providers use for patients during home visits. It is divided into phases, including hemostasis, inflammation, proliferation, and remodeling. The current study revealed that the healing time was affected by the anatomical site of the wound and took longer in pressure ulcers, undermined edge wounds, and infected wounds.
