BACKGROUND: Nurses\' knowledge of pressure injuries causes and risk factors helps to prevent their occurrences and protect the patient.
OBJECTIVE: To assess the level of knowledge of medical device-related pressure injuries and to identify risk factors that affect the knowledge.
METHODS: A cross-sectional design was used in this study considering a convenience sample from critical care nurses. The nurses were invited to complete the Medical Device-Related Pressure Injuries Knowledge Questionnaire.
RESULTS: About 71 nurses participated in the study. The mean score of MDRPI_KQ was 23.28 ± 4.14 out of 36. Mann-Whitney Test did not show statistically significant relationships between the MDRPI_KQ mean score and related variables (p > 0.05). The regression results indicated that the three predictors explained 46.4% of the variance (R2 = 0.215, F(3, 6.114) = 3.75, p = 0.001). It was found that the Frequency of encountering a patient with MDRPIs significantly predicted MDRPI_KQ score, job position, and assuming the care responsibility for MDRPIs in the department.
CONCLUSIONS: Poor knowledge of pressure injuries can negatively affect patient care so training programs and policies should be developed based on the level of knowledge and practices of the staff to be more effective.

OBJECTIVE: The objective of the present study is twofold: to describe the prevalence and incidence of pressure ulcers (PUs) among ICU patients during the COVID-19 pandemic, and to identify the risk factors associated with the development of PUs in this cohort of ICU patients.
METHODS: Retrospective cohort study of adult critical care patients admitted in two general ICUs of two different countries (Sweden and Portugal) between March 1st, 2020, and April 30th, 2021, through the analysis of the electronic health record database. The prevalence and incidence were calculated, and a multivariate logistic-regression model was used to calculate odds ratios (ORs), of possible risk factors of PU development.
RESULTS: The sample consisted of 1717 patients. The overall prevalence of PU was 15.3 %, and the incidence of ICU-acquired PUs was 14.1 %. Most of the pressure ulcers documented in this study were at the anterior part of the body (45.35 %) and regarding classification, Category 2 (38.40 %) and Category 3 (22.71 %) pressure ulcers together accounted for over fifty percent of the cases recorded. In the multivariate logistic regression model for PU, age, having COVID-19 (OR = 1.58, 95 % CI: 1.20-2.09), use of mechanical ventilation (OR = 1.49, 95 % CI: 1.13 = 1.97), use of vasopressors (OR = 1.31, 95 % CI: 1.00-1.70), having a Braden risk score ≤16 at admission (OR = 1.63; 95 % CI: 1.04-2.56), and length of stay (LOS) (OR = 1.43, 95 % CI 1.03-2.00 if LOS 90-260 h, OR = 2.34, 95 % CI: 1.63-3.35 if LOS >260 h) were associated with the likelihood of developing an ICU-acquired PUs.
CONCLUSIONS: When adjusted for covariates patients with COVID-19 had a higher risk for PU development during the ICU stay compared to patients without COVID-19. Health care personnel in ICU may consider incorporating COVID-19, age, use of mechanical ventilation, vasopressors and estimated LOS in addition to a comprehensive risk assessment including both a risk score and clinical assessment.

Pressure ulcers (PUs) represent a burden to the health economy and patients alike. Despite national and international guidelines regarding the management of risk, the incidence and prevalence across England remains high. Detecting early the risk of PUs is paramount, and requires using a valid risk assessment tool alongside clinical judgement and management of associated risk factors. There is a need to implement prevention strategies. Introducing care bundles for pressure ulcers, for example SKIN, SSKIN and most recently aSSKINg, is designed to guide clinicians and reduce variations in care. This article presents a review of the evidence on compliance with guidelines, frameworks, pathways or care bundles within primary and secondary care settings. This article focuses on the literature review that was conducted to inform a subsequent clinical audit of compliance with the aSSKINg framework in a Community NHS Foundation Trust in the South East of England.

Background: Despite available knowledge how to prevent the risk of pressure ulcers, malnutrition, poor oral health and falls among older persons in nursing homes, these risks still frequently occur and cause a major burden for older persons; furthermore, for the health care system, they are extremely costly. One way to combat these risks is to register the prevention process in quality registries. However, the increasing older population worldwide is going to put high demands on those working with this group of people. Objective: To explore how nurse aides, registered nurses and managers in nursing homes experience working with the prevention of pressure ulcers, malnutrition, poor oral health and falls in general and according to the quality register Senior Alert care process. Methods: A qualitative study was conducted in nursing homes in a municipality in southern Sweden. We purposively sampled nurse aides, registered nurses and managers (n = 21) working in nursing homes registered in the quality register Senior Alert, who then participated in one of five focus group semistructured digital interviews held between February and April 2020. The interviews were audio recorded. Data were analysed using reflexive thematic analysis. Results: Our findings explore how nurse aides, registered nurses and managers experience working with the prevention of pressure ulcers, malnutrition, poor oral health and falls in nursing homes both in general and according to Senior Alert. The following four themes were generated during the analysis: (1) is included in the everyday work, (2) requires team effort, (3) requires handling many challenges and (4) requires finding strategies. Conclusion: The prevention of pressure ulcers, malnutrition, poor oral health and falls among older persons in nursing homes is complex. There is a commitment and responsibility among nurse aides, registered nurses and managers regarding preventive work and team effort, and finding useful strategies is necessary for the work to be successful. However, challenges, both at the individual and organizational levels, are involved, which implies that smoother organizational routines facilitating this preventive work are needed. Although nurse aides, registered nurses and managers are good at finding strategies that facilitate this work, one of the main challenges seems to lie in the variety of knowledge found among those working in nursing homes, particularly among nurse aides. This challenge was voiced by all the professionals, which suggests the need for a tailored educational intervention aimed at increasing the related knowledge among those working in nursing homes to enhance preventive work.

BACKGROUND: Each year, millions of Americans develop truncal pressure ulcers (PUs) which can persist for months, years, or until the end of life. Despite the negative impact on quality of life and escalating costs associated with PUs, there is sparse evidence supporting validated and efficacious treatment options. As a result, treatment is based on opinion and extrapolation from other wound etiologies. The ideal reconstructive plan maximizes the patient\'s nutritional status, incorporates the basic tenets of wound bed preparation (debridement, offloading, proper moisture balance, reduction of bacterial burden), and employs diagnostics to guide therapeutic intervention. The use of combination therapies can potentially overcome several of the barriers to wound healing. Negative pressure wound therapy (NPWT), a commonly used modality in the management of PUs, facilitates healing by stimulating the formation of granulation tissue and promoting wound contraction; however, NPWT alone is not always effective. Clinical studies examining microbial bioburden in PUs determined that most ulcers contain bacteria at levels that impede wound healing (>104 CFU/g).
OBJECTIVE: Thus, we hypothesized that adding an anti-microbial agent to decrease both planktonic and biofilm bacteria in the wound would increase the efficacy of NPWT.
METHODS: In this prospective study, twenty patients with recalcitrant PUs that previously failed NPWT were treated with a biofilm-disrupting agent (Blast-X, Next Science, Jacksonville, FL, USA) in combination with NPWT. Fluorescence imaging was used to follow bacterial burden and guide therapy.
RESULTS: In total, 45% of the PUs reduced in size over the course of the four-week study, with a resolution of bacterial fluorescence in the NPWT dressing and wound bed seen in an average of three weeks.
CONCLUSIONS: The combination of an antibiofilm agent and NPWT reduced bacterial levels and improved wound healing in recalcitrant PUs.

BACKGROUND: Sacrococcygeal sinus ulcers are caused by pressure sores, trauma, or surgery. Several surgical techniques have been developed for its treatment; however, studies are ongoing to develop the ideal method. The present study aims to introduce an innovative application of gluteus maximus muscle flaps (GMMFs) packing combined with local random pattern skin flaps (RPSFs) in repairing sacrococcygeal sinus tracts (SSTs).
METHODS: This was a prospective analysis study conducted on the patients (n = 26) with SSTs underwent an innovative repairing surgery in Qilu Hospital of Shandong University, China between December 2015 and December 2020. The repairing surgery was GMMFs combined with RPSFs. The demographic information and the clinical parameters including operative time, postoperative healing time, and recurrence rate were used to evaluate the efficacy of the operation.
RESULTS: Except one case of partial necrosis at the edge of the flap due to severe fibrosis, which was cured after dressing change, all the other cases showed effective healing after the operation.
CONCLUSIONS: The combined application of GMMFs and RPSFs for the treatment of sacrococcygeal sinus tracts gains the advantages of short operative time, quick postoperative recovery, and low postoperative recurrence rate.

OBJECTIVE: To: (1) report on the prevalence of community-acquired pressure injuries (CAPIs) in patients admitted into the acute care setting; (2) examine the socio-economic and home environment associated with CAPIs; and (3) understand the challenges of caring for patients with CAPIs at home.
METHODS: This mixed-method study recruited patients admitted with CAPIs in the acute care hospital between March 2021 to June 2022. The hospital\'s pressure injury (PI) database was used to screen patients admitted with CAPIs. A purposive sample of CAPI patients and their caregivers participated in this study. A cross-sectional survey study was first performed to examine the prevalence of CAPIs and the socio-economic and home environment factors. Semi-structured interviews were conducted to understand the caregivers\' challenges in caring for patients with CAPIs at home.
RESULTS: The CAPI prevalence was reported at 1.1 % during the study period (1039 had CAPIs out of 97 912 patients admitted to the hospital). A total of 70 caregivers and patients consented to participate in the study. The mean age of patients was 84.2 (SD = 10.4) years old; 68.6 % (n = 48) were females. Majority presented with a deep tissue injury (DTI) (37.1 %; n = 26) or unstageable PI (31.4 %; n = 22). More than half of the patients had alternating air mattresses at home (54.3 %; n = 38), and only 10 % (n = 7) had positioning wedges and used a sliding sheet for turning. The mean age of the caregivers was 43.4 years old (SD = 13.1), and 84.3 % (n = 59) were female. Continuous data were summarised using means and standard deviations, and categorical data were summarised using frequencies and percentages. Logistic regression found no significant socio-demographic and clinical predictors of patients having PI stages 2, 3, and 4 compared to patients with DTI and unstageable PI. Challenges to caring for PI at home included high financial burden, physical limitations, and personal challenges in CAPIs management.
CONCLUSIONS: CAPIs are prevalent among older patients admitted to the acute care setting. Understanding the influence of socio-economic factors is crucial for developing comprehensive strategies to mitigate the occurrence and impact of PIs. Ongoing support and education to the caregivers in the community is essential to address the reported challenges in PI care.

The aim of the present study was to compare the therapeutic effects of activated platelet-rich plasma (PRP) prepared from elderly individuals and young adults to treat pressure ulcers (PUs), and to accumulate a theoretical basis for allogeneic PRP treatment of PUs in elderly patients.
Whole blood was extracted from elderly individuals aged >65 y and young adult volunteers for PRP preparation, and platelet concentrations in whole blood and PRP were compared. Growth factors released from activated PRP were assayed using the enzyme-linked immunosorbent assay. C57BL/6 mice were divided into three groups: the control saline, elderly-PRP (Group A), and young adult-PRP (Group B). Ischemia-reperfusion injury-induced PUs were established on the backs of mice. PUs were photographed on days 0, 5, and 10 to assess their sizes. Specimens were collected on day 10 and subjected to hematoxylin and eosin and Masson\'s staining. Immunohistochemical staining for CD31 was conducted to evaluate vascular formation, and cell invasion was assessed using a Transwell assay. The action of PRP on transforming growth factor-beta (TGF-β)-dependent fibroblast activity and epithelial-mesenchymal transition was analyzed using immunofluorescence and Western blotting in vitro.
The platelet concentrations in whole blood and PRP of young adults were significantly higher than that in elderly individuals. The two PRP treatment groups had similar platelet enrichment coefficients of PRP. After activation, PRP from young adults produced significantly higher levels of platelet-derived growth factor, TGF-β, and vascular endothelial growth factor than PRP from elderly individuals (P < 0.05). The concentrations of platelet-derived growth factor, TGF-β, and vascular endothelial growth factor were positively correlated with the platelet concentrations in whole blood and PRP. The effects of PRP in regulating the expressions of TGF-β, α-smooth muscle actin, vimentin, and E-cadherin were observed in vivo and in vitro. The two PRP treatment groups exhibited better wound healing than the control group, as evidenced by more re-epithelialization, higher collagen content, skin fibrosis, and more blood vessel formation over time. Group B exhibited better wound healing than Group A (P < 0.05).
PRP exhibits potent wound healing ability in PU therapy, and PRP from young adults is seemingly superior to that from elderly individuals because of a higher concentration of platelets and increased production of growth factors.

UNASSIGNED: Pressure ulcers remain a worldwide problem.
UNASSIGNED: To introduce an intermittent and feasible wound treatment method for the treatment of pressure ulcers in elderly patients.
UNASSIGNED: This surgical procedure was performed on eight elderly patients suffering from pressure ulcers. Microskin measuring 0.1 × 0.1 centimeters was cut from a small amount of thin skin and then grafted onto the wound surface in conjunction with closed negative pressure therapy.
UNASSIGNED: Seven patients had their wounds closed after a single surgery, while one patient required two surgeries to close the wound.
UNASSIGNED: Autologous microskin implantation for the treatment of pressure ulcers in the elderly is an effective method to close the wound, which can prevent the elderly from living with wounds in their later years and is a viable treatment option.

UNASSIGNED: The pressure ulcer is a complication developed from dementia. The aim of this study is to study the association between the development of pressure ulcers and the use of acupuncture therapy in patients with dementia.
UNASSIGNED: We performed a retrospective 1:1 propensity score-matched cohort study to investigate the association between acupuncture therapy and the risk of pressure ulcers in patients with dementia.
UNASSIGNED: A total of 8,994 patients were identified, 237 patients in the acupuncture cohort and 362 patients in the no-acupuncture cohort developed pressure ulcers. A reduced cumulative incidence of pressure ulcers was observed in the acupuncture cohort (P<0.001). The association between acupuncture and reducing the incidence of pressure ulcers was not affected by sex, age, residence, income, or comorbidities. The variables of etiologies to cause dementia did not change the final result. In the subgroups analyses, the patients without medication for dementia control had a significantly lower rate of pressure ulcers development when they had accepted acupuncture therapy (log-rank test, P<0.001).
UNASSIGNED: Our results revealed the association between acupuncture therapy and a reduced incidence of pressure ulcer development in patients with dementia. This finding offers important ideas for further research.
