This study is the descriptive research intended for identifying the reciprocal relationship between the knowledge of nursing and performance of pressure ulcer prevention that registered nurses at the aged care hospital possess. A total of 317 nurses who had been working at the aged care hospital for 4 months from March 1 2014 to June 1 2014 were chosen as research group. The data were collected by means of self-reported questionnaire and data were analyzed with descriptive statistics. The knowledge of nursing on pressure ulcer depending on general characteristics of research group had the significant difference in each item of clinical experience, education program, education time and education frequency(p<.05), In the performance of pressure ulcer prevention only the education frequency among various general characteristics showed significant differences(p=.40). The knowledge of nursing related to pressure ulcer had the low negative correlation with the performance of nursing(rho=-.137, p<.05). Among the factors disturbing nursing performance of pressure ulcer prevention the shortage of nursing staff appeared to be 57.7%. From the result of this study it was revealed that both increasing the education frequency of preventive nursing and managerial consideration concerning the shortage of nursing staff were needed more rather than the knowledgement of preventive nursing to improve the nursing performance of pressure ulcer prevention.

In this article, we reported a single case of ischemic fasciitis in a young woman with a progressive immobilization due to a multifocal demyelinating disease of central nervous system, which appeared on an extensive pressure ulcer of the sacral region treated with 10 days of negative-pressure wound therapy (NPWT). Wound examination revealed a significant nontender brown neoformation (9 cm in length × 10 cm in width × 7 cm in height), fixed to the sacrum, presenting hard consistency, and grown in the central portion of the sacral pressure sore. The histologic examination showed central fibrinoid necrosis, and vascular and atypical fibroblastic proliferations, and a diagnosis of ischemic fasciitis was made. Ischemic fasciitis is a rare benign proliferation of atypical fibroblasts that occurs in physically weak patients with reduced mobility. In the literature, the relationship between the use of NPWT on pressure ulcers and the development of ischemic fasciitis is, to the best of our knowledge, not described yet.

Purpose: This study was done to compare clinical nurses' knowledge and visual differentiation diagnostic ability for the pressure ulcer classification system (PUCS) and incontinence-associated dermatitis (IAD). Methods: A convenience sample of 602 nurses took the pressure ulcer classification system and incontinence-associated dermatitis knowledge test (PUCS & IAD KT) and completed the visual differentiation tool (VDT), consisting of 21 photographs with clinical information. Results: The overall mean score for correct answers was 14.5 (${\pm}3.2$) in PUCS & IAD KT and 11.15 (${\pm}4.9$) in PUCS & IAD VDT. Incorrect responses were most common for statements related to stage III, IAD for PUCS & IAD KT, and suspected deep tissue injury (SDTI), unstageable, and stage III for PUCS & IAD VDT. Significant correlations were found between PUCS & IAD KT and VDT (r=.48, p<.001). Factors affecting scores for PUCS & IAD VDT were PUCS & IAD KT, frequency of pressure ulcer, IAD management and participation in wound care education programs. Conclusion: Results indicate that nurses have an overall understanding of PUCS & IAD, but low visual differentiation ability regarding stage III, SDTI, and unstageable ulcers. Continuing education is needed to further improve knowledge and visual differentiation ability for PUCS & IAD.

Introduction: Pressure ulcers, often found in patients with mobility issues, particularly elderly patients, are increasing in prevalence. Their treatment is complex, with recovery more challenging in advanced stages, and certain factors can delay healing. Case Presentation: An 87-year-old male developed a grade IV pressure ulcer on his left greater trochanter following lumbar fractures and subsequent percutaneous vertebroplasty in 2021. Despite potential surgical recommendations, his treatment consisted of daily wet dressings, acupuncture from July 2021 to February 2022, and Gami-sipjeondaebo-tang beginning August 2021. The ulcer, initially measuring 6 cm×6 cm and showing a red wound without necrosis, healed completely and showed no signs of recurrence as of August 2023. Conclusion: A grade IV pressure ulcer was effectively treated using wet dressing, acupuncture, and Gami-sipjeondaebo-tang, demonstrating no recurrence over a 1.5-year period.

Purpose: An animal model of pressure ulcers was experimentally-induced with the use of greater trochanter of rats. Methods: Twelve male Sprague-Dawley rats were used in this study and they were randomly divided into 4 groups: Group I (n=3, 120 mmHg, 2 hr), Group II (n=3, 120 mmHg, 3 hr), Group III (n=3, 140 mmHg, 3 hr) and Group IV (n=3, 140 mmHg, 4 hr). The rats were anesthetized with 100 mg/kg of ketamine. The pressure ulcers were induced by using a personally-designed pressing apparatus. After 5 days, the wounds were photographed and excised. Results: After 5 days of induced pressure ulcers, it was observed that Group I and Group II responded with Grade I and Grade II, respectively, while Group III and Group IV responded with Grade III. Conclusion: According to the result of this study, it can be concluded that the pressure ulcers were induced the characteristic grades of pressure ulcer classification by adjusting the degree and the duration of compression.

Purpose: A network meta-analysis was conducted to assess the comparative effects and ranks of repositioning for pressure ulcer prevention in adults. Methods: A network meta-analysis was performed in a frequency method, using the "netmeta" package of R software version 4.1. The effects of repositioning intervention were confirmed by the odds ratio. The comparative ranking of the repositioning effects was confirmed using the cumulative probability (P-score). Results: Seven intervention studies were included in this study. Based on the P-score, the use of the repositioning system was ranked as the most effective among all interventions (P-score 78.7%). Next was 3~4-hour repositioning combined with memory foam mattress use (P-score 77.2%), use of wearable sensor (P-Score 61.4%), 2-hour repositioning combined with memory foam mattress use (P-score 59.1%), 2-hour repositioning combined with powered air pressure redistribution mattress use (P-score 18.0%), and 4-hour repositioning combined with powered air pressure redistribution mattress use (P-score 18.0%). Conclusion: This study provides information on the relative comparative value of various repositioning interventions to prevent pressure ulcers using network meta-analysis. This is expected to be useful for nurses' decision-making when applying repositioning interventions in clinical practice

Background Complication rates after flap coverage for pressure ulcers have been high historically. These patients have multiple risk factors associated with poor wound healing and complications including marginal nutritional status, prolonged immobilization, and a high comorbidities index. This study utilizes the National Surgical Quality Improvement Program (NSQIP) to examine perioperative outcomes of flap coverage for pressure ulcers. Methods Data from the NSQIP database (2005-2015) for patient undergoing flap coverage for pressure ulcers was identified. Demographic, perioperative information, and complications were reviewed. One-way analysis of variance and Pearson chi-square were used to assess differences for continuous variables and nominal variables, respectively. Multivariate logistic regression was performed to identify independent risk factors for complications. Results There were 755 cases identified: 365 (48.3%) sacral ulcers, 321 (42.5%) ischial ulcers, and 69 (9.1%) trochanteric ulcers. Most patients were older male, with some degree of dependency, neurosensory impairment, high functional comorbidities score, and American Society of Anesthesiologists class 3 or above. The sacral ulcer group had the highest incidence of septic shock and bleeding, while the trochanteric ulcer group had the highest incidence of superficial surgical site infection. There was an overall complication rate of 25% at 30-day follow-up. There was no statistical difference in overall complication among groups. Total operating time, diabetes, and non-elective case were independent risk factors for overall complications. Conclusions Despite patients with poor baseline functional status, flap coverage for pressure ulcer patients is safe with acceptable postoperative complications. This type of treatment should be considered for properly selected patients.

Background Various surgical management methods have been proposed for ischial sore reconstruction, yet it has the highest recurrence rate of all pressure ulcer types. A novel approach combining the advantages of a perforator-based fasciocutaneous flap and a muscle flap is expected to resolve the disadvantages of previously introduced surgical methods. Methods Fifteen patients with ischial pressure ulcers with chronic osteomyelitis or bursitis, who underwent reconstructive procedures with an inferior gluteal artery perforator (IGAP) fasciocutaneous flap and a split inferior gluteus maximus muscle flap from January 2011 to June 2016, were analyzed retrospectively. The split muscle flap was rotated to obliterate the deep ischial defect, managing the osteomyelitis or bursitis, and the IGAP fasciocutaneous flap was rotated or advanced to cover the superficial layer. The patients' age, sex, presence of bursitis or osteomyelitis, surgical details, complications, follow-up period, and ischial sore recurrence were reviewed. Results All ischial pressure ulcers were successfully reconstructed without any flap loss. The mean duration of follow-up was 12.9 months (range, 3-35 months). Of 15 patients, one had a recurrent ulcer 10 months postoperatively, which was repaired by re-advancing the previously elevated fasciocutaneous flap. Conclusions The dual-flap procedure with an IGAP fasciocutaneous flap and split inferior gluteus maximus muscle flap for ischial pressure ulcer reconstruction is a useful method that combines the useful characteristics of perforator and muscle flaps, providing thick dual padding with sufficient vascularization while minimizing donor morbidity and vascular pedicle injury.
