Evaluating the healing status of pressure injuries is important to planning medical and nursing care.
Purpose: A descriptive, retrospective study was conducted to determine the healing status of pressure injuries among critically ill immobile patients.
Methods: Data were obtained via medical record review of all patients admitted to a Turkish university hospital's anesthesiology intensive care unit (ICU) between January 2008 and December 2015. Demographic (age, gender), medical (comorbidities, diagnosis, length of ICU stay), and pressure injury characteristics (number, location, stage, healing status, length, width, exudate amount, tissue type) were evaluated along with Pressure Ulcer Scale for Healing (PUSH) Tool scores. Data from all patients >18 years of age with an ICU stay >24 hours who had a pressure injury and whose records were complete were included in the study. Data were expressed as number, percentage, and mean and median values. Wilcoxon test, Spearman's correlation analysis, and chi-square test were performed as appropriate. Pressure injuries were considered healed when the PUSH score equaled zero.
Results: The study sample comprised 359 patients (60.97 ± 19.31 [range 19-95] years, 217 men, median length of stay 25 [range 1-363] days) with 672 pressure injuries. Most pressure injuries were located on the coccyx (278 [41.4%]), and 153 (22.8%) healed during ICU stay. Older age (r = 0.167; P = .002) and length of ICU stay (r = 0.238; P = .0001) were significantly correlated with having multiple pressure injuries. There was a statistically significant relationship between pressure injury location and stage and healing status (χ2 = 28.993, P = .0001; and χ2 = 60.200, P = .001, respectively). The lowest percentage of injuries healed were on the coccyx and were stage 4 and unstageable. Overall, the mean first PUSH score was significantly higher than the last assessment score (8.99 ± 3.82 to 7.28 ± 5.22, respectively; z = -10.807; P = .0001).
Conclusion: Many immobile ICU patients had multiple pressure injuries, especially patients who were older and who had a longer length of stay. Healing scores for pressure injuries were better at discharge or transfer and 22% of injuries were healed. Prospective studies comparing all factors that may contribute to pressure injury healing are warranted. .
